Opis:: Introduction and aim. Smoking widely affect oral health, including its role in the development of periodontitis. Saliva contains an antioxidant system and various enzymes. The study was designed to evaluate the activity of salivary alpha amylase among individuals who smoke and have periodontitis. Material and methods. A total of 100 participants were included, with 50 cases (cigarette smokers with periodontitis) and the remaining 50 nonsmokers with healthy periodontium as the control group. Saliva samples were collected to measure salivary alpha amylase activity. Results. Smokers with periodontitis had significantly higher levels of salivary alpha amylase compared to the control group(177.96±14.5 vs 94.04±19.6 IU/mL, p<0.001). Additionally, there was a weak negative correlation between the level of alpha amylase and the age of the patients (p=0.01, r=0.376). However, no correlation was found between the level of alpha amylase and the duration of smoking (p=0.584, r=0.079). Conclusion. There is a significant increase in salivary alpha amylase levels among smokers with periodontitis. No correlation was found between age and salivary alpha amylase levels. However, a weak positive correlation was observed between the duration of smoking and salivary alpha amylase activity.

Opis:: This study investigated the possibility of producing juice by hydrolyzing acha starch using crude amylase from germinated maize. Planted maize was monitored for seven days to determine germinative capacity and amylase activity of the seed. Extracted acha starch was hydrolysed using wet homogenised maize seedlings in an incubator at 62-68 °C for 6-8 hours. Colour, pH, titratable acidity (TTA), °Brix and sensory attribute of the juice were determined using standard method. A commercial malt beverage was used as reference. The maize sample had a mean capacity of 95% while its maximum amylase activity occurred at day 4. The pH, TTA, and °Brix of the juice were obtained as 4.5, 0.85 and 10 respectively. Colour values for L*, a*, and b* were 37.64, 7.6, and 15.3 respectively. Sensory analysis showed no significant difference between the juice and reference sample in terms of taste and colour. However, significant differences were observed in aroma and overall acceptability. Hence, malt beverages can be produced using this method but requires certain additives to impart prevalent aroma associated with malt beverages.

Opis:: The aim of this study was to investigate the impact of feed supplements with alfa-amylase and beta-glucanase (Optipartum C+ 200) on ingestive-related behaviour biomarkers registered with real-time sensors: rumination behaviours and reticulorumen parameters (pH and temperature). Cows (n=20) in the treatment group (TG) were fed with Optipartum C+ 200 (Enzymes feed supplement: Alfa-Amylase 57 Units; Beta-Glucanase 107 Units) from 21 days before calving until 30 days after calving with a feeding rate of 200 g/cow/day. Cows (n=22) in the control group (CG) were fed a feed ration without feed supplement. Measurements started from 6 days before calving and continued until 21 days after calving. The following indicators were registered: with the RumiWatch System: Rumination time; Eating time; Drinking time; Rumination chews; Eating chews; Drinking gulps; Bolus; Chews per minute; Chews per bolus. With the SmaXtec system: the temperature, pH of the contents of the cows’ reticulorumens, and cows’ walking activity. According to our results, feed supplementation with alfa-amylase and beta-glucanase (Optipartum C+ 200) in the TG group resulted in increases in the following parameters: 9% rumination time and eating time, 19% drinking time, 11% rumination chews, 16% eating chews, 13% number of boluses per rumination, 5% chews per minute and 16% chews per bolus. The rumination time showed a strong, positive relation with rumination chews and bolus indicators in both groups (TG and CG) (p<0.001); while the rumination time in both groups of cows showed an opposite direction and was negatively related to eating time and eating chews (p<0.05). We found a 1.28 % lower reticulorumen pH and a 0.64 % lower reticulorumen temperature in cows fed with the supplement compared with cows in the control group. Cows in TG were 8.80% more active than those in the CG group. For improvement of ingestive-related behaviour we suggest adding a feed supplement with alfa-amylase and beta-glucanase (Optipartum C+ 200).

Opis:: As polycarbonate is frequently used in many products, its accumulation in landfills is absolutely harmful to the environment. The aims of this study were the screening and isolation of polycarbonate-degrading bacteria (PDB) and the assessment of their ability in the degradation of polycarbonate (PC) polymers. Nine-month buried- -PC films were used for PDB isolation and identification. The biodegradation ability of the isolates was determined by growth curve, clear zone formation, lipase and amylase production, AFM and FTIR. Bacillus cereus and Bacillus megaterium were identified and considered as PDB. The degradation ability of B. megaterium was significantly higher than that of B. cereus. Both were lipase and amylase positive. AFM and FTIR results showed the initiation of bacterial attachment. The PC biodegradation ability of isolates can be very efficient. Finding such efficient isolates (which was less studied before) will promise a decrease in plastic contamination in the future.

Opis:: Amaranthus caudatus L. seed germination was studied under different levels of water deficit induced by PEG 6000 in laboratory conditions. PEG at osmotic potentials -0.2 to -0.3 MPa at 24°C in darkness delayed germination and reduced final germination percentage. PEG solutions at osmotic potential lower than -0.3 MPa almost totally blocked seed germination. Ethephon was much more effective than GA3 in reversing PEG-caused inhibition of A. caudatus seed germination. PEG decreased α-amylase activity after 14 h incubation. It decreased β-amylase activity after 14 and 20 h, and caused an increase in total dehydrogenase activity only after 20 h of incubation. Unlike GA3, ethephon increased α-amylase activity in seeds after 12 and 14 h of incubation under water deficit. After 20 h of incubation there was no difference in α-amylase activity in any of the treatments. Neither ethephon nor GA3 affected the activity of β-amylase and dehydrogenase.

Wykazano zmienność zawartości białka ogółem, białka rozpuszczalnego w soli sodowej siarczanu dodecylu (SDS), gluteniny wysokocząsteczkowej oraz białka nierozpuszczalnego. Stwierdzono, że mąka badanych odmian różniła się aktywnością enzymów proteolitycznych i a-amylazy, mierzonej liczbą opadania. Wykazano skorelowanie liczby opadania z zawartością białka ogółem i zawartością pentozanów rozpuszczalnych. Pentozany rozpuszczalne w większym stopniu różnicowały odmiany pszenicy niż pentozany nierozpuszczalne i zawartość pentozanów ogółem. Odmiany pszenicy różniły się zawartością skrobi w mące. Zawartość skrobi była istotnie skorelowana z zawartością białka ogółem i białka nierozpuszczalnego.
he test material were 11 cultivars of winter wheat harvested in the years 1994-1996 (Begra, Panda, Olcha, Almari, Gama, Wilga, Emika, Kobra, Roma, Jawa, Juma), coming from the Strain Test Station at Tarnów Śląski. In the cultivars tested there was found a variability in the contents of total protein, SDS - soluble and insoluble protein, as well as of high-molecular glutenin. Their flour appeared to differ in the activity of proteolytic enzymes and alpha-amylase measured by the falling number. The falling number was proved to have been correlated with the contents of total protein and soluble pentosans. The wheat cultivars were more differentiated by soluble pentosans than by the insoluble and total ones. Different, too, was the content of starch in them, the latter having been significantly correlated with total and insoluble protein contents.

Opis:: The clinical assessment of autonomic nervous system (ANS) functioning, enabling the diagnosis of autonomic neuropathy present in the course of many diseases, is currently based on performing simple cardiovascular reflexes (Ewing tests), analyzing heart rate variability (HRV) or heart rate turbulence (HRT), examining skin sweating or recording neurophysiological tests (e.g. microneurography). Laboratory assessment of ANS function is very scarce and practically only includes the plasma assessment of noradrenaline as a surrogate for the biochemical indicator of sympathetic activity. Recently, the possibility of evaluation of selected compounds present in saliva as laboratory markers of not only oral diseases but also systemic diseases has been raised. This work focuses on a brief description of the anatomy and physiology of the salivary glands and describes the formation of saliva, its composition and the use of this bodily fluid in laboratory diagnostics. In addition, the paper specifically discusses the possibility of determining selected compounds that are considered to reflect autonomic activity. A review of the literature indicates primarily four proteomics: two neuropeptides (vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) that are co-transmitters in autonomic fibers, chromogranin A, a synaptic vesicle protein and α-amylase, a hydrolytic enzyme pre-digesting carbohydrates in the oral cavity. These are currently the most widely investigated agents for their usefulness as laboratory markers of ANS activity.

Opis:: The tomato leaf miner, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), is one of the most destructive pest of solanaceae and it prefers tomato (Solanum lycopersicum L.). The aim of the current study was to investigate the effects of a wide range of seed proteinaceous extracts from different plant families against T. absoluta α-amylase activity. The effect of pH on the inhibitory activity of seed extracts showed that seed extracts of amaranth along with a wheat cultivar (Alvand, Aflak, Sarvdasht, Alborz, and Kavir) produced more than a 50% inhibition of the insect amylase. Aflak wheat seed extract at 10 μg, inhibited 81% of the insect amylase. This percent was the highest inhibition achieved. The other proteinaceous seed extracts had a lower effect on the enzymatic activity. Probit analysis showed that Aflak, Kavir, Alborz, Alvand, Sarvdasht, and amaranth inhibited the amylase activity with an I50 of 1.94, 3.24, 3.46, 3.31, 4.97, and 15.39 μg, respectively. The effect of pH on the inhibition of the α-amylase showed the highest inhibition of Amaranth and wheat, at a pH value of 8.0, which corresponds to the pH of the insect’s gut. Gel electrophoresis assays confirmed the spectrophotometric assays showing that the α-amylase of the insect gut was affected by the presence of the seed extracts. In the gel assay, a high concentration (14 μg protein) of amaranth proteinaceous seed extract greatly decreased the intensity of the α-amylase band. A high concentration of the Aflak wheat cultivar (10 μg protein) caused the disappearance of the amylase band in the gel. Thus, it is concluded that the physiochemical environment of the insect gut affects the interaction between digestive α-amylase and the metabolites. The experiments showed that seed proteinaceous extracts from non-host plant species, produced more inhibition of the insect amylase when compared to the host plant species. It appears that with evolution, adaptation took place so that insect/s could overcome the plant metabolites.

Opis:: Single and double-gene Rhtl, Rht2, Rht3, Rht1 + Rht2 and Rht3 + Rht2 isogenic lines of wheat in four parental rht varieties were grown in drilled yield trials at four sites in 1989. The same lines were also grown in 1988 together with hybrid genotypes from CHA (chemical hybridising agent) F₁ production plots. In the inbred lines shorter than one metre, Rht alleles reduced total shoot biomass by shortening the straw; mass of straw per unit plant height was unaffected. Highest grain yield was obtained from plant heights between 70 and 100 cm. The Rht genotype achieving this stature varied according to parent varietal height. The hybrids grown allowed comparisons between intra- and inter-varietal crosses over a range of Rht genotypes. In F₁ hybrids positive heterosis was observed for plant height, grain yield and mean grain weight. Highest yields were obtained from inter-varietal hybrids carrying one, two or three doses of Rht1 or Rht2 or one dose of Rht3. An Rht3lrht hybrid showed resistance to premature α-amylase production during grain ripening.

Opis:: The influence of different factors on amylolytic activity Bacillus cereus (2 strains) and Bacillus mycoides (2 strains), isolated from soil samples and water of Turawa Lake has been studied. Effect of physiological (pH of reaction mixture in the range of 4.0–8.0, temperature of reaction from 30 to 60 oC) and nutritional parameters (the carbon sources and they concentration in medium) were examined spectophotometricaly for their effect on amylase production. The results obtained showed, that in view of all studied factors the least favorable value of pH was 5.0, while in most cases the most favourable for the process of amylase production were following values 7.0 and 8.0. Moreover, it has been stated that the lowest amount of amylase was noted at 30 oC, and the highest at 60 oC. In case of amylolytic activity, in view of all temperatures the most effective strain was B. mycoides A134 whereas the least B. mycoides G3. The best results of amylase production have been achieved for all remaining strains in two cases – on maltose and glucose medium at all tested temperatures. Additionally, soil occurring strains preferred lower concentration of potato starch (ie 1 %) when compared with water strains which favoured higher concentration (5 %).
Celem badań była ocena wpływu różnych czynników na aktywność amylolityczną Bacillus cereus (2 szczepy) i Bacillus mycoides (2 szczepy) wyizolowanych z gleby i Jeziora Turawskiego. Metodą spektrofotometryczną badano wpływ pH mieszaniny reakcyjnej w zakresie od 5.0 do 8.0 i temperatury w zakresie od 30 oC do 60 oC oraz źródła węgla i jego koncentracji w podłożu na poziom produkowanych amylaz. Stwierdzono, iż najgorszą wartością pH do syntezy amylaz było 5.0, natomiast najlepszą, w większości przypadków pH 7.0. Uwzględniając zakres badanych temperatur, najwyższą aktywność uzyskano w temp. 60 oC, natomiast najniższą w temp. 30 oC dla wszystkich testowanych szczepów. Najbardziej aktywnym szczepem był B. mycoides A 134, natomiast najmniej B. mycoides G3.

Opis:: The albino Wistar rats were used to investigate the effect of thyroxine administration on the activity of citric acid, α-Amylase, creatine phosphokinase (CPK), creatinine, cholesterol and triglycerides level in blood serum and citric acid in liver and kidney. Two groups of rats were taken for the experiment. One group was injected subcutaneously with 200 μl of thyroxine/50 g of body weight, the other group served as control. The animals were vivisected with anesthesia after intervals of 24, 48, 72 and 96 hours α-Amylase and CPK levels in blood; citric acid level in liver and kidney of control and thyroxine treated rats. The results showed that the α-Amylase activity remained unaltered (100 g/h/l) throughout the experiment. However, citric acid level found to be 460 mg in the liver and 415 mg in kidney of control rats. The values slightly increased to 480 and 680 mg in respective tissues of thyroxine treated animals for 24 hr. The values decreased in 48 and 72 hours of treatment. Further the values found to be increased after 96 hours of treatment. Although the thyroxine treatment altered citric acid, Creatinine, Cholesterol, Triglycerides and CPK levels in the tissues, the serum α-Amylase was not influenced by the thyroxine. The study suggests that the thyroxine acts as a regulator all the above parameters in the cellular level.

Opis:: One of the most health- and sometimes also life-threatening symptoms of bulimia nervosa is vomiting. It may lead to severe complications, e.g. electrolyte imbalance, metabolic alkalosis, hyperchloremia, hypokalemia, metabolic disturbances, heart arrhythmia, vitamin deficit, damage of posterior wall of pharynx and oesophagus, erosion of dental enamel. Detection of a specific predictor of unfavourable consequences of the disease might help to define a group of patients more at risk of developing uncontrollable vomiting in the course of bulimia nervosa, as well as to provide a means of monitoring frequency of vomiting in non-cooperative patients. The aim of this study was to explore correlations between frequency of vomiting in the course of bulimia nervosa and selected variables, e.g. symptoms of depression, anxiety, hostility, dissatisfaction with own body image and elevated levels of amylase in serum and urine. Using a specially designed questionnaire, Hamilton Depression Scale, Hamilton Anxiety Scale, Buss-Durkee Hostility Inventory and Body Image Questionnaire, we studied 55 patients (54 females and 1 male) with a diagnosis of bulimia nervosa (acc. to ICD-10), treated at the out-patients clinic (52 persons) and institutionalised (3 persons) since 2003 thru 2005. Each participant of the study was tested for serum and urine amylase level. Study protocol has been approved by Bioethical Committee. In the study group we noticed a significant positive correlation between frequency of vomiting and severity of anxiety and hostility and amylase level in serum and urine. Furthermore, a significant positive correlation was noticed between amplitude of body mass fluctuations, severity of hostility and amylase level in serum and urine. No associations were found between frequency of vomiting, presence of depression and dissatisfaction with own body.
Jednym z najbardziej niebezpiecznych dla zdrowia, a często i dla życia objawów żarłoczności psychicznej (ZP) są wymioty. Mogą one prowadzić do poważnych powikłań, takich jak: zaburzenia elektrolitowe, zasadowica metaboliczna, hiperchloremia, hipokaliemia, zaburzenia metaboliczne, zaburzenia rytmu serca, niedobory witamin, uszkodzenie tylnej ściany gardła i przełyku, erozja szkliwa zębów. Znalezienie predyktora niekorzystnych konsekwencji choroby mogłoby pomóc w wyodrębnieniu pacjentek bardziej zagrożonych ryzykiem wymiotów w przebiegu ZP, a także dałoby szansę monitorowania częstości wymiotów u pacjentek niewspółpracujących. Celem badania było ustalenie związku pomiędzy częstością wymiotów w przebiegu ZP a wybranymi zmiennymi, takimi jak: obecność objawów depresji, lęku, wrogości, niezadowolenia z obrazu własnego ciała oraz podwyższonych stężeń amylazy w surowicy krwi i moczu. Za pomocą specjalnie opracowanego kwestionariusza oraz Skali Depresji Hamiltona, Skali Lęku Hamiltona, Kwestionariusza Wrogości Bussa-Durkee, Kwestionariusza Obrazu Ciała przebadano 55 pacjentów (54 kobiety i 1 mężczyznę) z rozpoznaniem ZP (wg ICD-10), leczonych w poradni (52 osób) oraz w oddziale (3 osoby) w latach 2003-2005. U każdego uczestnika badania oznaczono stężenia amylazy we krwi i w moczu. Na przeprowadzenie badania uzyskano zgodę Komisji Bioetycznej. W grupie badanej stwierdzono istotną dodatnią korelację pomiędzy częstością wymiotów a nasileniem objawów lęku oraz wrogości oraz stężeniem amylazy w surowicy i moczu. Ustalono także występowanie istotnej dodatniej korelacji pomiędzy wielkością zmian/wahań masy ciała a nasileniem wrogości oraz stężeniem amylazy w surowicy i moczu. Nie obserwowano związku między częstością wymiotów a obecnością depresji oraz niezadowolenia z własnego ciała.
