Opis:
High doses of synthetic antioxidative vitamins: A, E, C and β-carotene are often used on long-term basis in numerous preventive and therapeutic medical applications. Instead of expected health effects, the use of those vitamins may however lead to cases of hypervitaminosis and even to intoxication. The article points out main principles of safety which are to be observed during supplementation with antioxidative vitamins. Toxic effects resulting from erroneous administration of high doses of those substances on organs and systems of the organism are also discussed. Attention is drawn to interactions of antioxidative vitamins with concomitantly used drugs, as well as intensification of adverse effects caused by various exogenous chemical factors. Moreover, the article presents the evaluation of supplementation with these vitamins, which was performed in large studies.

Celem pracy była ocena stężenia witamin A, E i C w osoczu krwi osób starszych, >65 roku życia, przed i po 30-to dniowej suplementacji witaminowej. Do badań zakwalifikowano 22 zdrowe osoby. Oznaczenia badanych witamin wykonano przy użyciu spektrofotometru dwuwiązkowego UV/Vis Lambda 14p (Perkin Elmer). Przed suplementacją stwierdzono obniżone wartości badanych witamin w surowicy. Zastosowana 30 dniowa suplementacja wpłynęła na zwiększenie zawartości badanych witamin u 15% badanych.
The aim of the work was the estimation of the vitamins A, E and C concentration in the plasma of 22 healthy elder persons, before and after 30 days of additional supplementation. Vitamins were determined with double beam spectrophotometer UV/Vis Lambda 14p (Perkin Elmer). Before additional supplementation the lower content of vitamins was observed. The 30 days diet supplementation by vitamins caused increase of their content in the serum in 15% adults.

Opis:
Rapidly growing commercial poultry production generates large amounts of waste. Waste that accumulates during the poultry slaughter process often remains unprocessed, becoming a serious threat to people’s health and the natural environment. Poultry production waste constitutes problems odour threat and dangerous sanitary threat. The aim of this study was to determine the population size of Escherichia coli and Clostridium perfringens in poultry waste and in successive stages of waste composting. Research material consisted of raw feathers collected immediately after the slaughter, samples of biological sludge from the centrifuge, mixture of straw, feathers and lime and processed compost. Microbiological analyses were conducted with the use of spread plate count method and the substrate was used in accordance with research standards. The size of population of microorganisms in the samples analyzed corresponded to the waste processing stage and group of microbes. The presence of C. perfringens strains was ascertained in all samples, whereas E. coli strains were identified only in raw feathers and centrifuge sludge, being most numerous in unprocessed material. A reverse trend was observed in case of C. perfringens with the highest population density in centrifuge sludge and least density in raw feathers.
Intensywnie rozwijająca się produkcja drobiarska wiąże się z generowaniem dużej ilości odpadów. Powstające produkty uboczne podczas uboju pozostawione w stanie surowym stają się poważnym zagrożeniem dla środowiska naturalnego i zdrowia ludzi. Mogą stwarzać problemy odorotwórcze oraz istotnie groźne zanieczyszczenie sanitarne. Celem przeprowadzonych badań było określenie liczebności E. coli i C. perfringens w odpadach drobiarskich oraz kolejnych etapach ich kompostowania. Materiał badawczy stanowiły świeże pióra bezpośrednio po uboju, osad biologiczny z wirówki, mieszanina słomy, pierza i wapna oraz kompost przerobiony. Analizy mikrobiologiczne wykonano metodą płytkową, wykorzystując wybiórcze podłoża zgodne z normami. Liczebność mikroorganizmów w badanych próbach zależała od fazy przerobu odpadu i analizowanej grupy drobnoustrojów. Obecność bakterii C. perfringens stwierdzono we wszystkich próbach, natomiast bakterie E. coli tylko w piórach surowych i osadzie z wirówki, przy czym najliczniej występowały w materiale nieprzetworzonym. Odwrotną tendencję zaobserwowano w przypadku C. perfringens, które najliczniej zasiedlały osad z wirówki, natomiast ich mniejszą liczebność stwierdzono w piórach surowych.

Opis:
The effect of vitamins E, C and ß -carotene supplementation in sows on the parameters of antioxidative/oxidative status during the postpartum period was investigated. Twenty four primiparous sows, divided into two groups (experimental and control), were included in the study. After the half-way point of pregnancy until farrowing, each experimental sow received feed supplemented twice a week with 200 mg of vitamin E and 1000 mg of vitamin C, and additionally, 70 mg of ß-carotene were administered via intramuscular injection, on day 14 and day 7 before farrowing. The control group was not supplemented. Blood samples were collected before supplementation (gestational day 57-58), 48 hours and 7 days after parturition. The following antioxidative and oxidative parameters were measured using spectrophotometric methods: glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT), vitamin C, vitamin E, thiobarbituric acid reactive substances (TBARS), and sulfhydryl groups (SH groups). In supplemented sows the erythrocyte activity of GSH-Px and CAT was found to be significantly higher on day 7 after farrowing and the activity of SOD was significantly higher at 48 hours postpartum, compared to the control group. The concentration of vitamins C and E in plasma of the supplemented group was found to be significantly higher and the content of TBARS was found significantly lower at both postpartum measurement points, compared to the control group. The content of SH groups was significantly higher on day 7 postpartum, compared to the control group. The study findings indicate that supplementation of pregnant sows with vitamins E, C and ß-carotene in the second half of pregnancy has beneficial effects on the antioxidative/oxidative balance in the postpartum period by increasing the antioxidative potential and reducing lipid and protein peroxidation.

Opis:
Background. Antioxidant vitamins such as alpha-tocopherol (vitamin E), ascorbic acid (vitamin C), and beta-carotene (provitamin A), play a significant role in protecting the body from an excess of free radicals. The vitamin content of the diet is thus very important. Objective. To assess whether the dietary intake of vitamins A, C and E is adequate in a selected group of adolescents living in Warsaw. Material and methods. The mean vitamin consumption was estimated using three-day dietary records whilst vitamin contents of selected foodstuffs were obtained from Food Composition Tables. Both were related to Polish nutrition standards applied to adolescents; i.e. EAR (Estimated Average Requirement) for vitamins A and C and AI (Adequate Intake) for vitamin E. Results. Dietary vitamin C in adolescents and vitamin E in girls were around 18-25% lower than that recommended. Diets that were deficient in vitamins C and E were recorded in 47% to 67% adolescents. Conclusions. It is therefore necessary to increase the consumption of vegetables and fruit which provide a valuable dietary source for these vitamins.
Wprowadzenie. Witaminy antyoksydacyjne – alfa-tokoferol (witamina E), kwas askorbinowy (witamina C) i beta-karoten (prowitamina A) pełnią istotną rolę w ochronie organizmu przed wolnymi rodnikami, dlatego odpowiednia zawartość tych witamin w diecie ma istotne znaczenie. Cel. Celem badań była ocena poziomu spożycia witamin A, C i E z produktami spożywczymi w wybranej grupie młodzieży zamieszkałej na terenie Warszawy. Materiał i metody. Średnie spożycie witamin oszacowano na podstawie badań przeprowadzonych metodą trzydniowego bieżącego notowania spożycia produktów spożywczych oraz przy zastosowaniu tabel wartości odżywczej produktów spożywczych i odniesiono do polskich norm dla młodzieży ustalonych na poziomie średniego zapotrzebowania (EAR) dla witamin A i C oraz na poziomie wystarczającego spożycia (AI) dla witaminy E. Wyniki. Zawartość witaminy C w diecie młodzieży oraz witaminy E w diecie dziewcząt była o około 18-25% niższa od zalecanej. Diety ubogie w witaminę C i E spożywało około 47-67% młodych osób. Wnioski. Istnieje potrzeba zwiększenia spożycia warzyw i owoców, jako ważnych źródeł tych witamin w diecie.

Opis:
The purpose of this investigation was to find out the level of lung reduced glutathione (GSH) and ascorbic acid in rats exposed to ozone (980±390 µg/m3, five weeks, eight hours a day ) under condition of different diet with vitamins E and C. The control rats were fed with commercial standard diet and were exposed to air. GSH was assayed by a spectrofluorimetric method and ascorbic acid was determinated by 2,4-dinitrophenylhydrazine method. The study revealed no statistically significant increase in pulmonary GSH and ascorbic acid in rats exposed to ozone which were fed commercial standard diet. When different diets of vitamins E and C were applied separately and together, the increase in lung ascorbic acid in the animals exposed to ozone was greater and statistically significant compared with respective control groups. Also, in the case of separate supplementation with vitamins E and C, the statistically significant increase of dose-dependent GSH was observed. When vitamins E and C were supplemented together, no changes in GSH level were noted. The observed increases in GSH and ascorbic acid may reflect the mobilization of these antioxidants to the lung under ozone-induced oxidative stress.
Celem pracy była ocena zawartości witaminy C i zredukowanego glutationu w tkance płucnej u szczurów żywionych paszą standardową oraz paszą standardową wzbogaconą wzrastającymi dawkami witaminy E i C w warunkach poddania ich przewlekłemu narażeniu na oddychanie powietrzem o zwiększonej koncentracji ozonu (980 µg/m3, 5 tygodni, 8 godzin dziennie). Grupy kontrolne stanowiły zwierzęta oddychające zwykłym powietrzem atmosferycznym i żywione paszą standardową. Przeprowadzone badania wykazały statystycznie nieistotny wzrost poziomu zredukowanego glutationu i kwasu askorbinowego w grupach zwierząt żywionych paszą standardową i poddanych ekspozycji na ozon. W grupach ozonowanych zwierząt żywionych paszą standardową wzbogaconą w sposób łączny bądź oddzielny witaminami E i C obserwowany wzrost poziomu witaminy C był wyższy oraz statystycznie istotny w stosunku do grup kontrolnych. Podobnie w grupach ozonowanych zwierząt żywionych paszą standardową wzbogaconą w sposób oddzielny witaminą E i C stwierdzono, statystycznie istotny i zależny od dawki odpowiedniej witaminy, wzrost poziomu zredukowanego glutationu w tkance płucnej. Zjawiska tego nie stwierdzono u ozonowanych zwierząt żywionych paszą standardową wzbogaconą w sposób łączny witaminami E i C.

Opis:
Chromium (Cr) is a very common element. It occurs in 2 oxidation states, Cr(III) and Cr(VI). Although Cr(III) is not considered an element essential for mammals, it raises lots of controversy due to its role in the body. While Cr(III) action should be considered an effect of pharmacological action, Cr(VI) is included in the first group of carcinogens for humans. Moreover, it induces numerous pathological changes in the respiratory, urinary, reproductive and digestive systems. In addition, Cr(VI) is used in many industry branches, causing millions of workers all over the world to be exposed to Cr(VI) compounds. A considerable number of the occupationally exposed individuals are in favor of a deep analysis of the mechanisms of Cr(VI) action and a search for a way to reduce its negative impact on the human body. Numerous reactive oxygen species inducing oxidative stress and causing various damage are produced during Cr(VI) reduction in the cells. A good balance between antioxidants and pro-oxidants can reduce Cr(VI)-induced damage. The influence of vitamins and microelements on the adverse Cr(VI) effects has no systematic research results summary. Therefore, this work focuses on the role of dietary antioxidants such as vitamins and microelements in the prevention of Cr(VI) adverse health effects. Numerous studies have revealed a protective influence of vitamins (mainly vitamins E and C) as well as microelements (especially selenium) on the reduction of Cr(VI)-induced adverse changes. A potential protective effect of these ingredients may be useful in occupational groups that are particularly exposed to Cr(VI). However, more research in this area is required.

Opis:
The paper deals with the trend for Penman- Monteith reference evapotranspiration and climatic water deficit during the first decade of the 21st century in Southern Romania vs the 20th century. For the first half of the year the monthly evapotranspiration values were higher for the first decade of the 21st century vs the means of the 20th century. However, the trend reverses for the second half of the year, but for the whole year the totals were higher for the first decade of the 21st century vs the totals of the 20th century. The yearly temperature means in the first decade of the XXI century showed an increase in the three locations studied, respectively, vs century XX. This warming is responsible to a great extent for the increase in evapotranspiration, and the relationship between evapotranspiration and temperature was highly significant. Water deficit decreased in Constanta and Pitesti, but there was a slight increase in water deficit in the same period in Bucharest-Baneasa. Water deficit increased in the first half of the year and decreased in the second half during the first decade of century XXI in all the three locations investigated vs century XX.

Opis:
This study investigated the phytochemical composition and antimicrobial activities of ethanol and methanol leaf extracts of Lantana camara Linn against some clinical pathogens. The ethanol and methanol extracts were obtained by soaking each of the powdered leaf in each solvent. The soaked powdered leaf was allowed to stand for four days at room temperature and later filtered using Whatman filter paper. The filtrate was further concentrated using rotary evaporator and then freeze-dried. The minimum inhibitory concentration (MIC) of the ethanol and methanol leaf extracts was carried out using agar well diffusion method. The phytochemical analysis was done using standard techniques. Data were analysed using Analysis of Variance (ANOVA) to test for significance. Means were separated using Duncan’s Multiple Range Test (DMRT). The results of the antimicrobial activity revealed that V. cholerae was the most susceptible while E. coli was the most resistant to plant extracts. The phytochemicals present in the plant leaf had antimicrobial properties and may serve as a good substitute for resistant human pathogens.

Opis:
In maize plant breeding aimed at producing a hybrid, it is necessary to characterize the parents and hybrids by their agronomic aspects and grain quality so that the processing industry may offer consumers a quality product and also improve its efficiency. This study evaluated the viscoelastic parameters of masa and the chemical and texture properties of tortillas obtained from parent lines (M-54, M55, and CML-242), two single crosses (M54xM55 and M55xM54), and one hybrid (H-70). The morpho- logy of the maize grains and tortillas was analyzed using scanning electron microscopy. The firmness of masa obtained from CML-242 and H-70 maize was higher than that from the other maize genotypes. M-54 tortillas showed the lowest crude fiber content. Otherwise, tortillas obtained from the M55xM54 hard grain had the lowest fat content and extensibility, while H-70 tortillas showed an intermediate breaking point and extensibility. M-54 and M54xM55 tortillas were softer due to their more swollen starch granules. In contrast, rigid tortillas were obtained from CML-242 and H-70. Grain hardness causes different morphology in starch and tortilla of maize genotypes. However, grain hardness did not influence the characteristics of texture in tortillas.

Opis:
Developmental mode and proximal structures are commonly accepted as the best for the recognition of high−level taxonomic categories within the Graptoloidea. The petalolithids and retiolitids are unique in possessing a virgellar ancora and in the latter, distal ancora development. The ancora structures are considered homologous, and the ancorate petalolithids are considered to be the direct ancestors to the retiolitids. The Retiolitidae are unique among the diplograptoids in possessing (1) outer, lateral, ancora sleeve walls (derived from distal extension of the ancora), and (2) a skeletal framework of bandaged lists between which are a succession of very thin and rarely preserved fusellar layers. Retiolitids possess different kinds of thecal profiles and two types of micro−ornamentation on the lists, and these have served to distinguish between the subfamilies Retiolitinae and Plectograptinae. Complete retiolitid morphological terminology is clarified and explained. Cladistic analysis of the retiolitids provides some measure of a better understanding of retiolitid evolution, but adds only modest support for the retention of the two subfamily categories.

Opis:
The aim of this study was to evaluate the efficacy of electroacupuncture in acute and chronic phases of radial and ulnar nerve injuries in histopathological, immunohistochemical and biochemical aspects. In the study, the rabbits were divided into four groups namely acute nerve injury (ANI) group, chronic nerve injury (CNI) group, positive control (PC) group and negative control (NC) group. In the ANI, CNI and PC groups, damage was created on the nervus radialis and nervus ulnaris by applying pressure for 60 seconds using a hemostatic forceps under anesthesia. No damage was created in the NC group. Fifteen sessions of electroacupuncture were applied to the rabbits in the ANI, CNI, and NC groups every other day using LI-4 (Large Intestine Meridian-4, He Gu), LI-10 (Large Intestine Meridian-10, Shou San Li), LR-3 (Liver Meridian-3, Tai Chong), and ST-36 (Stomach Meridian-36, Zusanli) electroacupuncture points. Electroacupuncture was not applied to the rabbits in the PC group. Decapitation was performed under general anesthesia at the end of electroacupuncture applications. After the euthanasia procedure, the samples obtained were evaluated for histopathological, immunohistochemical and biochemical parameters. In conclusion, degenerative foci in the treatment groups were found to be fewer than in the PC group whereas NGF and S-100 immunoreactivity were higher in the treatment groups than in the PC group. Whereas no statistically significant difference was observed between the treatment groups and the NC group in terms of oxidative stress factors, there was a statistically significant difference between the treatment groups and the PC group. In light of all these data, we have concluded that electroacupuncture is an effective treatment method for peripheral nerve injuries.

The number of cancer patients in Brazil is increasing and part of the patients are submitted to brachytherapy treatment using iridium-192 wire and iodine-125 radioactive seeds. The Nuclear Energy Research Institute established a programme to produce iridium-192 wire and iodine-125 radioactive seeds. With the purpose of settling a laboratory for iridium-192 sources production, a wire activation method was developed and a hot cell for the wire manipulation, quality assurance and packaging was built. The iodine-125 seeds consist of a welded titanium capsule containing iodine-125 adsorbed onto a silver rod. Concerning the setup of the local production, the following activities were carried out: superficial treatment of the silver rod, development of a process to absorb the iodine in the silver rod, welding methodology to seal the seeds, leakage and contamination test and source activity measurement.

Opis:
The expected effect of ultrasonic disintegration of excess sludge is particle dispergation and cell lysis i.e. the elimination of sludge microorganisms and the release of the contents of dead cells into the sludge liquid which results in an increase in chemical oxygen demand. Sonolysis also formed the basis for the intensification of volatile fatty acids production during the acid fermentation of excess sludge treated ultrasonically. In this study the investigations into the direct effects of excess sludge ultrasonic treatment revealed an increase in volatile fatty acid concentration directly (without fermentation process) after the ultrasonic treatment which is closely related to sonolysis.

Opis:
In offshore industry activities, the suitable onboard provision of assets location and geospatial marine information during operations is essential. Currently, most companies use its own data structures, resulting in incompatibility between processes. In order to promote the data exchange, oil and gas industry associations have pursued initiatives to standardize spatial information. In turn, the IMO - International Maritime Organization - started the implementation of e-Navigation policy, which is the standardization of technologies and protocols applied to maritime information and navigation. This paper shows relationship and integration points between maritime activities of oil and gas industry and e-Navigation technologies and processes, highlighting geospatial information. This paper also preludes out an initiative for a suitable product specification for the offshore oil and gas industry, compliant with e-Navigation and IHO S-100 international standards.

Opis:
Caviidae is one of the groups of rodents with the greatest ecomorphological disparity, and with currently three known lineages: Caviinae (cuises), Dolichotinae (maras), and Hydrochoerinae (capybaras). Caviinae include small caviids represented by three extant genera (Microcavia, Cavia, and Galea) and three fossils forms (Dolicavia, Palaeocavia, and Neocavia). In Argentina, the fossil record of Caviinae is continuous and abundant since the late Miocene. Neocavia, specifically, is represented by different species recorded in the late Miocene–Pliocene. Here, we describe a new species of Neocavia from the late Miocene–early Pliocene of the Cerro Azul Formation (La Pampa Province, Argentina), and provide a re-description of already known species (Neocavia lozanoi and “Neocavia depressidens”). Also, we perform a more comprehensive review of the genus and include the Neocavia species in a phylogenetic context within Caviinae. We analyze the main patterns of the evolution of the tympanic bullae within Caviidae, and infer about a possible occasional fossorial habit of Neocavia. The morphological and phylogenetic analyses indicate that Neocavia is more closely related to Dolicavia and Microcavia than to the other Caviinae, and confirm the monophyly of the genus, with at least two clearly differentiable species. Since this study cannot confirm the systematic position and validity of “N. depressidens”, we suggest not to use this taxon as a biostratigraphic indicator.

Opis:
This study aimed at the simultaneous treatment of wastewater obtained from swine and generation of bioenergy in form of electricity from the energy stored in the organic component of the wastewater. The Open circuit voltage, current, power density and microbiological and physicochemical parameters were monitored. An initial Open circuit voltage of 516mV, Current of 0.29mA, and Power density of 32.74mW/m2 were recorded, which increased to give maximum Open Circuit Voltages of 836mV, Current of 0.49mA, and Power density of 88.45mW/m2. The results revealed that The Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Organic carbon, Total Soluble solids (TSS), Ammonia, Ammonium and Ammonium-Nitrogen all showed percentage decrease of 85.92%, 51.74%, 78.16%, 98.87%, 55.87%, 55.79% and 55.90% respectively while parameters such as Total Dissolved Solids (TDS), Nitrate, Nitrate-Nitrogen, Phosphates, Phosphorus and Orthophosphates however increased after treatment to give a percentage increase of -273.60%, -131.65%, -134.85%, -168.77%, -159.26%, and -157.03% respectively. Bacteria isolates identified at the biofilms on the anode were Corynebacterium specie, Bacillus specie, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Streptococcus faecalis. The results from this study further exacerbate the Bioelectricity production as well as wastewater treatment potentials of the Microbial Fuel Cell technology.

Opis:
Proterochampsians are a South American endemic group of non-archosaurian archosauriforms with morphological characteristics recollecting Recent crocodilians, and therefore have been proposed as aquatic species. However, this has not been based on careful examination of anatomical and histological features. We provide a review of the morphological and histological evidence present in the skeleton of proterochampsids and discuss its implications for inferring the lifestyles of these organisms. Anatomical features such as a secondary palate, marginal dentition, palatine teeth, morphology of the tail, limb modification, and dermal armor are reviewed, and details of histological structures are described based on bone thin sections. Histological examination reveals a predominance of fibrolamellar bone tissue, suggesting rapid periosteal osteogenesis and therefore overall fast bone growth. The existence of discontinuities (LAGs) demonstrates that these animals responded to changes in their environment. Ecomorphological features do not provide definitive evidence for the lifestyles of proterochampsids, but allow us to propose a terrestrial/amphibious condition. The same is true of the histological features, particularly compactness of the bone.

The obtained results demonstrated that the sintering temperature is an efficient and simple tool for controlling the size of crystallite particles, thus affecting the resulting magnetic properties. Straightforward relationship between the sintering temperature and the size of crystallites was found, meanwhile no other crystalline phases than the spinel one were detected by two independent analytic methods.

Opis:
Background. Vitamin C is one of the most important water-soluble vitamins. It is responsible for many important functions in the body, including: it has a positive effect on maintaining immunity, protects the body against free radicals, and also participates in the synthesis of hormones. Juices can be a good source of this vitamin. Most of the juices available on the market are processed products. Untreated juices, which do not contain added preservatives, sugar and are not pasteurized, constitute a smaller group on the market. Therefore, this group of juices can be a valuable product in human nutrition. Objective. The aim of the study was to analyze the content of ascorbic acid (AA), dehydroascorbic acid (DHAA) and vitamin C (TAA) in non-preserved juices, depending on their type and storage time. Material and methods. The analysis of TAA, AA and DHAA content in juices was carried out in ten types of non- preserved juices from two companies (A and B), purchased in a chain of retail outlets. The analyzed juices in company A were: sauerkraut and carrot, grapefruit, orange, apple and mandarin, while in company B: orange, apple, apple and quince, grapefruit and mandarin. In test 1, the first ten juices were analyzed, in test 2 - another ten juices after one month, in test 3 - juices from test 2 were used, and three days after opening the package and storing the juices in standard refrigeration conditions, the stability test of AA was analyzed. The AA and TAA contents were determined using the high performance liquid chromatography (HPLC) method. The DHAA content was calculated by subtracting the AA content from the TAA content. Results. The highest TAA content was found in citrus juices, i.e. grapefruit, orange and mandarin, and the lowest in sauerkraut and carrot juices and apple juice. Moreover, ascorbic acid in apple juice was characterized by the lowest durability. Conclusions. In the production of non-preserved apple juice, consideration should be given to the natural protection of ascorbic acid by the addition of citrus or other fruit juice, vegetable juice or by using a mild technology in the production process.

Opis:
The capacity of Microbial fuel cells (MFCs) to produce voltage and concurrently treat abattoir waste water was investigated in MFCs that used 0.1M potassium ferricyanide (K3[Fe(CN)6] as catholytes. Physicochemical, electrochemical and Microbiological properties of the MFCs were monitored. The open circuit voltage (OCV) readings were taken at 3 hours interval and maximum OCV of 965mV was recorded. Also, The physicochemical characteristics of the MFCs revealed that the pH decreased by 0.2 after treatment; Chemical Oxygen demand, biochemical oxygen demand, total suspended solids, ammonia, and total nitrogen reduced by 88.4%, 65.56%, 43.88%, 60% and 60% respectively. However, Phosphate increased by 54%. The bacterial isolates from the raw abattoir wastewater were Staphylococcus aureus, Bacillus cereus, Bacillus subtilis, Enterococcus faecalis, Enterobacter aerogenes, Escherichia coli and Micrococcus luteus while Enterococcus faecalis, Bacillus cereus and Escherichia coli were isolated from the biofilms on the anode. Microbial fuel cells therefore have capacities for simultaneous waste water treatment and electricity generation.

We studied the temperature and concentration dependence of the POPC/C$\text{}_{12}$EO$\text{}_{2}$/water ternary system and identified and characterized the different phases occurring. The thermal behaviour is slightly dependent on the surfactant to lipid molar ratio R$\text{}_{s}\text{}_{/}\text{}_{l}$ . At low surfactant content the behaviour is similar to the binary lipid/water system. Similarly at low lipid contents the system behaves similarly to the surfactant/water mixture. However, at molar ratios R$\text{}_{s}\text{}_{/}\text{}_{l}$ between 2 and 3 a new hexagonal phase forms which is peculiar to the mixture. $\text{}^{2}$H NMR measurements indicated the existence of a lamellar phase containing also curved surfaces additional to the flat ones. The surface area per surfactant molecule was calculated to 0.23 nm$\text{}^{2}$ which is in good agreement with the cross-section of a paraffinic chain.

The effects of feeding, fasting, and re-feeding on the ruminal profile of growing cattle were studied. Ruminal fluid and urine samples were obtained from 12 crossbred steers weighing approximately 300 kg during the following periods: 11 h of normal feeding (postprandial period), 48 consecutive hours of fasting, and followed by 48 h of re-feeding. Fasting promotes changes in the ruminal profile, such as an increase in ruminal pH, reduction in the number of rumen protozoa and bacteria, and decrease in the urinary excretion of allantoin; however, it does not change the urinary uric acid excretion rate. The overall mean ruminal pH was higher during fasting (7.53±0.27) in comparison to those at normal feeding (6.72±0.25) and re-feeding (6.62±0.31) (p<0.05). During re-feeding, the ruminal profile returned to normal, except for the protozoa count, which despite a slight increase only after 48 h of re-feeding, did not recover to baseline values.

Opis:
This study aimed to investigate antioxidant and anti-inflammatory activities of a commercial product of noni (Morinda citrifolia) juice. Carrageenan-induced rat paw edema was employed as inflammatory model. One control and three experimental groups were formed. Experimental groups were administered noni juice alone, noni juice+carrageenan, and carrageenan alone. Oxidant and antioxidant capacity were determined by d-ROMs test and BAP test, respectively. Plasma concentrations of endothelin-1 and leptin were measured by ELISA. Measurements were performed at zero time and 2nd hour of inflammation. Oxidant capacity decreased in noni-received groups at 2nd hour (p=0.019). Antioxidant capacity of the group which received noni alone was found to be higher at 2nd hour (p=0.036). Plasma concentrations of endothelin-1 and leptin were notably lower in noni-received groups (p=0.001 and p=0.021, respectively). The results show that the commercial noni juice investigated has pronounced antioxidant and anti-inflammatory activities.

Opis:
In cultural-heritage-related indoor environments, biological particles represent a hazard not only for cultural property, but also for operators and visitors. Reliable environmental monitoring methods are essential for examining each situation and assessing the effectiveness of preventive measures. We propose an integrated approach to the study of biological pollution in indoor environments such as libraries and archives. This approach includes microbial air and surface sampling, as well as an investigation of allergens and pollens. Part of this monitoring plan has been applied at the Palatina Library in Parma, Italy. However, wider collections of data are needed to fully understand the phenomena related with biological contamination, define reliable contamination threshold values, and implement appropriate preventive measures.

Opis:
The protein kinase c-erbB-2 belongs to the family of receptor tyrosine kinase and is involved in oncogenesis. The present study predicts different phosphorylation sites of HER2/c-erbB-2 which are important in preventing or developing cancer, especially breast cancer. Sequence homology showed highest homology (77%) with epidermal growth factor receptor kinase domain. According to PROSITE search result, active sites of c-erbB-2 are N-lobe (glycine rich phosphate binding loop). Catalytic loop with presumptive catalytically active of Asp108 is phosphorylated by tyrosine protein kinase. A-loop, activation loop, becomes phosphorylated and activates the substrate binding. The study strengthens our knowledge regarding HER2 signaling by the detection of uncharacterized signaling proteins, establishing phosphorylation of an activation loop and helps us to make assumptions about the role of such previously unidentified proteins. On the basis of importance of HER2 in breast cancer as well as in other diseases, this study provides fruitful information for designing new therapeutic strategies.

Opis:
A new hydrochoerine rodent, Cardiatherium calingastaense sp. nov. (Caviidae), is described based on the specimen INGEO-PV 87. It was recovered from the late Miocene Las Flores Formation, cropping out at the Puchuzum locality, San Juan Province, Argentina. The new species is based on a particular combination of characters, among which the following can be highlighted: p4 with internal fissures equally deep as in Cardiatherium paranense, secondary external fissure as in Cardiatherium patagonicum, and lacking the fifth internal fissure and supernumerary internal fissure, as in C. paranense; m3 with a conspicuous labial column in the posterior ramus of the second prism; very deep primary and secondary external fissures in upper cheek teeth, the former producing a labial strong step-shaped profile in M2; sagittal crest on the parietals; bullae small in ventral view; scars of the origin of the masseter medialis muscle with an anterior projection up to the level of the incisive foramen and the maxilla-premaxilla suture. The phylogenetic analysis supports the taxonomic proposal of creating a new species of Cardiatherium and shows C. calingastaense sp. nov. as the sister group of the other species of the genus. The lineage leading to the clade Cardiatherium + largest capybaras would have originated at least during the Chasicoan SALMA (early late Miocene). Cardiatherium calingastaense sp. nov. adds to the previous record of Cardiatherium chasicoense and Cardiatherium paranense in the late Miocene of San Juan and Mendoza provinces, respectively, thus increasing the diversity of capybaras in central-west Argentina.

Wprowadzenie i cel pracy. Wirusowe zapalenie wątroby typu C ze względu na bezobjawowy przebieg oraz brak skutecznej szczepionki zostało uznane przez Światową Organizację Zdrowia za jedno z największych zagrożeń epidemiologicznych. Celem pracy jest analiza źródeł wiedzy na temat wirusowego zapalenia wątroby typu C, poznanie wiedzy grupy badanych na temat możliwości wykrycia wirusa HCV w organizmie oraz poznanie opinii ankietowanych na temat poziomu poinformowania populacji polskiej na temat tej choroby. Materiał i metody. Badanie ankietowe zostało przeprowadzone wśród 115 osób zamieszkałych na terenie województwa lubelskiego w wieku od 32 do 55 lat. Uzyskane wyniki badań zostały poddane analizie statystycznej z wykorzystaniem testu chi-kwadrat oraz współczynnika korelacji V Cramera. Wyniki. Zdecydowana większość badanych ma wiedzę dotyczącą możliwości wykonywania badań diagnostycznych w kierunku zakażenia HCV. Wyniki badań wykazały, iż głównym obecnym źródłem wiedzy badanej grupy na temat wirusowego zapalenia wątroby typu C jest telewizja. Natomiast, za wiarygodne źródło informacji respondenci uznali lekarza rodzinnego, od którego chcieliby uzyskać informacje na ten temat. Jednocześnie ponad 80% ankietowanych przyznało, że niewiele wie o wirusowym zapaleniu wątroby typu C. Wnioski. Badana grupa posiada wiedzę na temat badań diagnostycznych wykrywających zakażenie HCV. Respondenci przyznali, że ich wiedza na temat wirusowego zapalenia wątroby typu C jest niewielka oraz chcieliby dowiedzieć się na ten temat więcej. Analiza opinii ankietowanych ustaliła, że wiarygodnym źródłem wiedzy na temat tej choroby jest personel medyczny.
Introduction and aim. Hepatitis C has been recognized by the World Health Organization as one of the largest epidemiological risks because of its asymptomatic course and lack of an effective vaccine. The aim of this study is to analyze the sources of knowledge about hepatitis C and methods of diagnostics of the hepatitis C virus, and to identify the opinions of respondents on the level of the information about the disease in the Polish population. Material and methods. A survey was conducted among 115 people living in the Lublin province, aged 32–55 years. The obtained results were statistically analyzed using the Chi-2 and Cramer›s V correlation coefficient. Results. The great majority of respondents had knowledge of the ability to perform diagnostic tests for HCV. The results showed that the main source of current knowledge about hepatitis C in respondents is television. However, respondents considered the family doctor a reliable source of information about the disease. At the same time, more than 80% of respondents stated that they had insufficient knowledge about hepatitis C. Conclusions. The study group is aware of the diagnostic tests for the detection of HCV infection. Respondents admitted that their knowledge about hepatitis C is small and would like to learn more about it. Analysis surveyed agreed that a reliable source of knowledge about the disease is the medical staff.
