Opis:
Human papillomavirus (HPV) is widely accepted as a causative agent of cervical cancer. The distribution and prevalence of HPV types depend on geographic region and demographic factors. The aim of this study was to investigate the relationship between the presence of various HPV types and the outcome of cytological examination. Cervical smears were obtained from 125 women from southern Poland: low grade squamous intraepithelial lesions (LSIL) - 44, high grade squamous intraepithelial lesions (HSIL) - 12, cervical carcinoma - 27 and 42 women without abnormality in cytology as a control group. DNA was extracted from the smears and broad-spectrum HPV DNA amplification and genotyping was performed with the SPF 10 primer set and reverse hybridisation line probe assay (INNO-LiPA HPV Genotyping, Innogenetics). HPV DNA was detected in approximately 72% cases, more frequently in women with squamous intraepithelial lesions and cervical carcinoma than in the control group (P < 0.0005). The most frequent type found was HPV 16 (37%), followed by HPV 51 (28%) and HPV 52 (17%). A single HPV type was detected in 51% positive cases, more frequently in cervical cancer specimens. Multiple HPV infection was dominant in women with LSIL and normal cytology. Prevalence of HPV 16 increased with the severity of cervical smear abnormality. For women HPV 16 positive, the relative risk (odds ratio) of the occurrence of HSIL and cervical cancer versus LSIL was 14.4 (95% CI, 3.0-69.2; P=0.001) and 49.4 (95% CI, 6.5-372.8; P < 0.001), respectively. Genotyping of HPV will allow better classification of women with cervical abnormalities into different risk groups and could be useful in therapy.

Opis:
The purpose of this study was to compare hybrid capture assay with PCRs using different primers for the L1, E6-E7 regions for the detection of human papillomavirus (HPV) genome. One hundred twenty-five cervical smears with normal (n = 42) and abnormal (n = 83) cytology were investigated. Those at high-risk for HPV were studied by hybridization antibody capture assay and PCR with the pU-1M/pU-2R primers. Target DNA from the HPV L1 region was amplified by SPF10 primer set and home-PCR with MY09/MY11 primers. The presence of HPV DNA in cervical smears was detected by SPF10 (in 72% of cases), MY09/MY11 (58%), hybrid capture (55%) and pU-1M/pU-2R (39%). Results obtained with the SPF10 and MY09/MY11 consensus primer sets as well as hybrid capture and pU-1M/pU-2R specific for high-risk types differed significantly (χ2, P < 0.0005). The correlation between assays with the use of SPF10 and MY09/MY11 was 86% and between hybrid capture and the pU-1M/pU2R technique - 78%. In 49% of samples HPV DNA was detected by the four methods, whereas in 12% only by the SPF10 primers. The most sensitive technique was found to be PCR with the use of SPF10 primers, while the most specific - the MY09/11 PCR method. It seems that home-PCR with MY09/MY11 primers could be applied in screening tests.

The purpose of this investigation was to indicate the most effective method of revitalizing degraded forest area. The different modifications of wood chips were used as a substitute for humus layer. The mites (Acari), and moss mites (Oribatida) as the bio-indicators of soil succession changes were used. The study began 2 years after planting of Scots pine seedlings on the land devastated by military activity, at the former military training ground (GPS: 53.156943N, 17.986440E). The soil on this area was in the type of rusty soils and subtype of the rusty algae soils. Scots pine seedlings were planted in spring 2011, in a distance 1.5×0.8 m. In one-factor experiment four soil mulching treatments were tested: 1. uncovered soil – control (C), 2. soil mulched with wood chips (W), 3. W + mycorrhizal preparation (WM), 4. W + forest litter (WL). Three replicates of microplots arrangement was applied. Each microplot was 5 m long with 3 rows of Scots pine. Each replication covers 10 rows. Mulching with wood chips was carried out on April 12, 2012. On October 25, 2012, the wood chips on the WM microplots were inoculated with the mycorrhizal biopreparation, and on the WL microplots, a 10% addition of fresh forest litter from the ripe fresh coniferous forest was applied. After the end of the growing season of 2012, 2013 and 2014, the measurement of the plants was carried out (the height, the root neck diameter, the length of one-year increments in the last whorl, the number of one-year increments of the last whorl and the lengths of one-year increments of the last whorl). The samples for acarological tests were collected four times. In total, 40 substrate samples with a volume of 50 cm3 each were collected from each treatment. Mites extraction was carried out for 7 days in Tullgren apparatus. Mites were identified to the order, and moss mites to the species or genus, including juvenile stages. Calculated: the average density of mites, the dominance index, the species richness, the diversity of moss mites, the average number of species, and the Shannon general species diversity index. The use of soil mulching with the Scots pine wood chips did not significantly affect the growth and developmental characteristics of the Scots pine plants. After mulching with wood chips, the total number of mites increased many times, and moss mites began to dominate among micro-arthropods. Mulching treatments increased the number and the species diversity of moss mites in the substrate. The number of moss mites increased the most in wood chips without additives. The highest species diversity was observed in the wood chips with the addition of forest litter. Among moss mites Tectocepheus velatus visibly dominated in all study treatments. Oppiella nova and Scutovertex sculptus also constituted numerous mites populations. The study shows that the wood chips are very useful for use in the regeneration of the devastated and degraded forest soils.

Opis:
Biogas plants are one of the most stable sources of renewable energy. Currently, there is a noticeable increase in the amount of post-production residues from agricultural production and agri-food processing (fruit and vegetable processing, fermentation, beet pulp, or lignocellulosic waste), which, can be used for biogas production after appropriate pretreatment. The aim of this study was to examine the possibility of using the biomass produced during the cultivation of grapes on a selected farm as a substrate for a biogas plant, taking into account the production process. The research was carried out in 2018-2020 in a vineyard located in the Sandomierz Upland in the south-eastern part of Poland. Own rooted vines were grown as a single continuous string with a trunk height of 40 cm and a length of one fixed arm approx. 0.9 m, on which six pivots were left every year after applying a short cut, from which 12-16 fruit shoots were derived, the so-called grapevines. Leaves were collected at random from three locations on the fruiting shoot, a total of 30 leaves in each replicate. Each sample consisted of 1/3 of the leaves collected at the bottom, 1/3 in the middle, and 1/3 at the top of the canopy. Leaf area was estimated with a model 3100 area meter on a sample of 30 leaves from each replicate. Both the quantity and quality of the obtained material as a substrate for methane fermentation were evaluated. Biogas yield tests in optimal conditions for mesophilic bacteria were conducted on three substrate samples referred to as ‘Regent’, ‘Seyval Blanc’, and ‘Solaris’. The yields of the tested material ranged from 51.0 to 59.0 Nm3 biogas per Mg of biomass.

Objectives The purpose of the study was to estimate training energy expenditure (TEE) and daily energy expenditure (DEE) in the Polish elite athletes engaged in endurance sports and power sports, and to compare their levels with the Polish energy intake standards. Material and Methods The study sample consisted of 30 athletes (15 women and 15 men) whose energy expenditure was estimated based on heart rate monitoring. Results The mean values of DEE obtained for women engaged in endurance sports (WE – women endurance) and power sports (WP – women power) were 3201±533 kcal and 3217±554 kcal, respectively. In the group of male athletes, the respective values were 4518±717 kcal for endurance athletes (ME – men endurance) and 4459±837 kcal for power athletes (MP – men power). The mean values of TEE for female athletes were 819±240 kcal (WE) and 1047±248 kcal (WP). Those obtained for male athletes were significantly higher: 1440±675 kcal (ME) and 1337±331 kcal (MP). Conclusions Unlike the demands of particular sport disciplines, an athlete’s sex proved to be a factor causing significant differences between the TEE and DEE of athletes representing different sport disciplines. Individual athletes were found to differ significantly in their demand for energy, which in some cases was considerably different from what energy intake standards propose.

Objectives: The objective of this work was to determine the dynamics of maximal anaerobic power (MAP) of the lower limbs, following a single whole body cryostimulation treatment (WBC), in relation to the temperature of thigh muscles. Materials and Methods: The subjects included 15 men and 15 women with an average age (±SD) of 21.6±1.2 years. To evaluate the level of anaerobic power, the Wingate test was applied. The subjects were submitted to 6 WBC treatments at -130°C once a day. After each session they performed a single Wingate test in the 15, 30, 45, 60, 75 and 90th min after leaving the cryogenic chamber. The order of the test was randomized. All Wingate tests were preceded by an evaluation of thigh surface temperature with the use of a thermovisual camera. Results: The average thigh surface temperature $(\text{T}_\text{av})$ in both men and women dropped significantly after the whole body cryostimulation treatment, and next increased gradually. In women $\text{T}_\text{av}$ remained decreased for 75 min, whereas in men it did not return to the basal level until 90th min. A statistically insignificant decrease in MAP was observed in women after WBC. On the contrary, a non-significant increase in MAP was observed in men. The course of changes in MAP following the treatment was similar in both sexes to the changes in thigh surface temperature, with the exception of the period between 15th and 30th min. The shorter time to obtain MAP was observed in women till 90th min and in men till 45 min after WBC compared to the initial level. Conclusions: A single whole body cryostimulation may have a minor influence on short-term physical performance of supramaximal intensity, but it leads to improvement of velocity during the start as evidenced by shorter time required to obtain MAP.

The aim of this study was to analyse the correlation between a new multiplex qPCR assay and a reference qPCR assay for assessment of the human papillomavirus (HPV16) load and the viral genome status. The study was performed on 100 HPV16 positive samples containing premalignant lesions and carcinomas. HPV16 E2 and E6 gene loads were assessed by two PCR methods. The load of E2 and E6 was normalized to the cell number by qPCR targeting the RNase P open reading frame. The physical state of the viral genome was determined as a ratio of E2/E6 copies number per cell. Among 100 samples analysed, there were no statistically significant differences in the E2 and E6 viral load evaluated by multiplex qPCR and qPCR, the correlation coefficients were 0.98 and 0.97, respectively. There were 19% of samples with the integrated, 73% with mixed and 8% with episomal state of viral genome detected by multiplex qPCR and 17%, 79%, 4%, respectively, found by qPCR. Prevalence of integrated and episomal forms estimated by multiplex qPCR was higher than the one obtained by qPCR (Chi2, p < 0.0001), but in samples with premalignant and malignant diagnoses no significant differences were demonstrated regardless of the methods used. Sensitivity and specificity of multiplex qPCR were 93.7% and 100% as compared with qPCR, the positive predictive value was 100%. In summary, the multiplex qPCR assay in respect of HPV16 load and the frequency of viral genome status was shown to be a sensitive and specific reference method. Simultaneous estimation of E2 and E6 genes in one reaction tube reduces the cost of testing.

Opis:
The aim of this study was to estimate the water needs of grapevines (Vitis vinifera L.) in the different regions of Poland. The requirements of grapevines water, considered as the crop evapotranspiration, were determined using the plant coefficient method. The grapevine plants crop evapotranspiration was measured using the reference evapotranspiration and plant coefficients. The plant coefficients were adapted to the reference evapotranspiration that was calculated using the Blaney‑Criddle’s formula, modified for Polish conditions by Żakowicz. The water needs of grapevines were determined for five agro‑climatic regions of Poland with the representative meteorological stations. The calculations of grapevines water requirements were carried out for the thirty‑year period determined from 1981 to 2010. The study was based on the six‑month growing season established from May 1 to October 31. Four months, including May, June, July and August, were considered as the irrigation period. The highest grapevines water requirements (440 mm) during the growing season, were observed in the north‑west and central‑east region of Poland. In turn, the lowest water requirements were revealed in the south‑east (414 mm) and north‑east (415 mm) region of the country. During the irrigation period, the highest grapevines water needs occurred in the central‑north‑west (355 mm) and central‑east (353 mm) region of Poland, while the lowest (329 mm) – in the south‑east region of the country. The upward time trend of the grapevines water requirements was observed both in the growing season and in the irrigation period. With the exception of the central‑north‑west region, this time trend was significant throughout Poland. The highest increase in the water needs of grapevines during the growing season (by 6.9 mm in each subsequent ten‑year period) occurred in the central‑east and south‑east region of Poland. In the irrigation period, the highest rise of grapevines water requirements was noted in the south‑west (7.4 mm decade ‑1) and south‑east (7.6 mm decade ‑1) region of the country. The highest rainfall deficit was observed in the central‑north‑west region of Poland; 125 mm during the growing season, and 117 mm in the irrigation period.

Opis:
The literature contains few studies on the effect of temporary soil drought on the development and productivity of pea (Pisum sativum L.) pods in relation to their position in the fruiting part of the stem. The aim of this study was to evaluate pod productivity of various pea cultivars in relation to varied weather conditions. Differences in precipitation during two growing seasons resulted in a decrease in yield of 0.62 t ha−1 in a dry year in comparison to a year with better water availability. Pisum sativum ‘Tarchalska’ proved to be the most stable in terms of the number of pods produced, whilst ‘Prophet’ was the least. Weather conditions and cultivars were the determinants of pod production. Pea pods were distinguished by their position on the productive node. Larger and more productive pods were found on the lowest four productive nodes (which had a longer period of nutrient accumulation) resulting in higher seed mass. Productivity increased in the year with favorable weather conditions, as more of the upper nodes were reproductive. The first four nodes produced 45–91% of the yield. The number of seeds in the first three nodes was significantly cultivar-dependent, whereas the number of seeds in pods at all nodes was determined by weather conditions. Significantly more seeds were formed from each node in the wetter year. Pisum sativum ‘Audit’ was not sensitive to weather conditions, producing the same yield in the both years of the study.
W piśmiennictwie spotyka się mało pozycji literatury dotyczącej wpływu okresowej suszy i posuchy na rozwój i produkcyjność strąków grochu w zależności od biosocjalnego położenia w części owocującej pędu. Dlatego celem przeprowadzonych badań była ocena produktywności różnych odmian grochu na tle zróżnicowanych warunków pogody. Zróżnicowanie opadów w sezonach wegetacyjnych skutkowało zmniejszeniem plonowania w roku suchym o 0.62 t ha−1. Najbardziej stabilna w ilości wykształcanych strąków była odmiana ‘Tarchalska’, a najmniej odmiana ‘Prophet’. Warunki pogody miały wpływ na biosocjalne położenie strąków na pędzie, a w konsekwencji na potencjał produkcyjny strąków. Cztery pierwsze okółki zapewniały od 45 do 91% plonu. Właściwości botaniczno-rolnicze odmian decydowały o liczbie nasion pochodzących z dolnych okółków (1–4). Liczba nasion w strąkach zawiązanych z kwiatów wyższych okółków była determinowana warunkami pogody. W roku bardziej wilgotnym formowało się istotnie więcej nasion z każdego okółka. Odmiana ‘Audit’ odznaczała się wysoką stabilnością plonowania w latach badań.

Opis:
The ash-leaved maple (Acer negundo L.) has low habitat requirements, which is why this species is often used in the reclamation of industrial areas. The development of the reclamation plantings depends on the optimal water soil conditions that can be controlled by watering treatments. However, the use of irrigation requires determining the water needs of the cultivated species. The objective of the study was to evaluate the water needs of the ash-leaved maple in the reclamation plantings, in the period of over three years after planting. The water needs of the ash-leaved maple were determined using the crop coefficients method. Potential evapotranspiration was calculated using the Blaney-Criddle’s formula that was modified for the Polish conditions by Żakowicz. The water needs of the ash-leaved maple were assessed for five agro-climatic regions of Poland, in the years 1981-2010. The water needs of the ash-leaved maple in the growing period (April-October) were the highest in the C-E (638 mm) and C-N-W (637 mm) regions, and the lowest in the N-E (598 mm) and S-E (601 mm) regions. In July, the highest water needs were noted in the C-N-W region (149 mm) and the lowest in the S-W region (129 mm). In the studied thirty-years period, there was a significant upward trend in the water needs of the ash-leaved maple both during the growing season (except for the C-N-W region) and in July, in all the considered regions.

The aim of this study was to analyse the correlation between HPV16 E6 variants and the physical status of viral genome (integrated, mixed, episomal) among patients with cervical cancer (n=40) and low-grade squamous intraepithelial lesions - LSIL (n=40). The study was performed on 80 HPV16 positive samples. HPV16 E6 variants were identified using PCR and DNA sequencing. Nucleotide sequences of E6 were compared with the prototype sequence (EUR-350T). The physical state of HPV DNA was determined as the ratio of E2/E6 copy number per cell. Twelve different intratypic variants were identified as belonging to European (in 77 samples) and North-American 1 (in 3 samples) sublineages. The most prevalent non-synonymous variant was EUR-350G, which occurred with similar frequency in cervical cancer and LSIL. The frequencies of additional mutations in variants with EUR-350T or EUR-350G sequences differed significantly. For the first time, missense mutations G122A, C153T and G188A were discovered in EUR-350G variant. The integrated viral genome was predominant in women with cervical cancer. The EUR-350T prototype and EUR-350G without additional mutations variants were prevalent in cervical cancer samples with the HPV16 characterized by integrated DNA. In summary, European variants of HPV16 E6 dominated in both cancer and LSIL group. The presence of EUR-350G favoured the occurrence of additional nucleotide changes. We showed that nucleotide changes occur significantly more often in the mixed form of viral DNA and in LSIL group and that the variants without additional mutations may promote integration of HPV16 genome.

Opis:
The therapeutic application of magnetic fi elds has experienced signifi cant growth in recent years. A small number of contraindications, as well as the lack of side effects makes both permanent magnets and alternating magnetic fi elds frequently used in physical therapy practice. In a signifi cant number of clinical studies the effi cacy of this physical factor as both an independent method, as well as supporting treatment programs has been confi rmed. In the last few years, a lot of emphasis is put on the fact that all therapeutic methods should have a scientifi c basis and their usage should meet the evidence based medicine criteria (EBM). Therefore, this work will focus on comparison of the use of permanent magnets and alternating low-frequency magnetic fi eld on the basis of the available literature, including mainly, a randomized double-blind trial. Analysis of the available literature on permanent magnet usage has shown clinical effi cacy in many diseases, however, placebo-controlled studies confi rm mainly the analgesic effect in patients after liposuction surgery, with diabetic neuropathy and with chronic pelvic pain. The use of the alternating low-frequency magnetic fi eld also leaves many questions to which scientists have still not found the answer. Randomized double-blind trial proved its therapeutic effi cacy in patients after knee arthroscopy, fractures and delayed bone unions, knee and cervical spine osteoarthritis as well as in case of leg ulceration. Alternating magnetic fi eld application has a wider therapeutic range in comparison to permanent magnets and its effectiveness is much better documented, both in clinical studies as well as randomized double-blind trials.

Terapeutyczne zastosowanie pól magnetycznych wykazuje w ostatnich latach znaczący rozwój. Niewielka liczba przeciwwskazań, jak również brak działań ubocznych przyczyniają się do częstego stosowania tych zabiegów w praktyce fizykoterapeutycznej. W znacznej liczbie prac klinicznych potwierdzono skuteczność tego czynnika fizykalnego zarówno jako samodzielnej metody, jak i wspomagającej w programach terapeutycznych. W terapii stosuje się zarówno magnesy stałe, jak i zmienne pola magnetyczne. W ostatnich latach kładzie się coraz większy nacisk na to, aby wszelkiego rodzaju metody lecznicze miały podstawy naukowe, a ich zastosowanie spełniało kryteria medycyny opartej na faktach (evidence based medicine). Autorzy niniejszej pracy skupią się zatem na omówieniu zastosowania magnesów stałych i zmiennego pola magnetycznego niskiej częstotliwości na podstawie dostępnej literatury obejmującej randomizowane badania na podwójnie ślepej próbie. Analiza dostępnej literatury dotyczącej stosowania magnesów stałych wykazała ich skuteczność kliniczną w wielu schorzeniach, badania z grupą placebo potwierdziły natomiast działanie głównie przeciwbólowe u pacjentów po zabiegach liposukcji, u osób z neuropatią cukrzycową oraz u pacjentek z przewlekłym bólem miednicznym. Zastosowanie zmiennych pól elektromagnetycznych niskiej częstotliwości również pozostawia wiele pytań, na które jak do tej pory naukowcy nie znaleźli odpowiedzi. W badaniach na podwójnie ślepej próbie udowodniono skuteczność terapeutyczną u pacjentów po artroskopii stawu kolanowego, złamaniach i opóźnionym zrostem kostnym, u osób ze zmianami zwyrodnieniowymi stawów kolanowych i kręgosłupa szyjnego, a także w przypadku owrzodzeń podudzi. Działanie pól zmiennych ma w porównaniu z magnesami stałymi znacznie większy zakres terapeutyczny, a skuteczność ich działania jest o wiele lepiej udokumentowana zarówno w badaniach klinicznych, jak i randomizowanych na podwójnie ślepej próbie.
