Texte intégralRésumé :
Context: Whereas researchers have provided estimates for the number of head impacts sustained within a youth football season, less is known about the number of plays across which such impact exposure occurs.Objective: To estimate the number of plays in which youth football players participated during the 2013 season and to estimate injury incidence through play-based injury rates.Design: Descriptive epidemiology study.Setting: Youth football.Patients or Other Participants: Youth football players (N = 2098; age range, 5−15 years) from 105 teams in 12 recreational leagues across 6 states.Main Outcome Measure(s): We calculated the average number of athlete-plays per season and per game using independent-samples t tests to compare age groups (5–10 years old versus 11–15 years old) and squad sizes (<20 versus ≥20 players); game injury rates per 1000 athlete-exposures (AEs) and per 10 000 athlete-plays; and injury rate ratios (IRRs) with 95% confidence intervals (CIs) to compare age groups.Results: On average, youth football players participated in 333.9 ± 178.5 plays per season and 43.9 ± 24.0 plays per game. Age groups (5- to 10-year-olds versus 11- to 15-year-olds) did not differ in the average number of plays per season (335.8 versus 332.3, respectively; t2086.4 = 0.45, P = .65) or per game (44.1 versus 43.7, respectively; t2092.3 = 0.38, P = .71). However, players from smaller teams participated in more plays per season (373.7 versus 308.0; t1611.4 = 8.15, P < .001) and per game (47.7 versus 41.4; t1523.5 = 5.67, P < .001). Older players had a greater game injury rate than younger players when injury rates were calculated per 1000 AEs (23.03 versus 17.86/1000 AEs; IRR = 1.29; 95% CI = 1.04, 1.60) or per 10 000 athlete-plays (5.30 versus 4.18/10 000 athlete-plays; IRR = 1.27; 95% CI = 1.02, 1.57).Conclusions: A larger squad size was associated with a lower average number of plays per season and per game. Increasing youth football squad sizes may help reduce head-impact exposure for individual players. The AE-based injury rates yielded effect estimates similar to those of play-based injury rates.

Texte intégralRésumé :
Oryza sativa japonica (ofada rice) is largely grown in Aramoko, Abakaliki and Ofada are communities and consumed by both the poor and rich in Nigeria. A total of twenty ofada rice farmlands were identified in each study area and rice samples were randomly collected, thoroughly mixed to make a representative sample from each farmland. Soil samples were collected in each farm to a depth of 5-15cm from at least eight different points and thoroughly mixed together to form a representative sample. The samples were thereafter taken to the laboratory for preparation and spectroscopic analysis. A well-calibrated NaI(Tl) gamma-ray detector was used in spectrometric analysis of the samples and descriptive statistics was used to analyze the results.
The respective mean 40K, 238U and 232Th activity concentrations in the rice were 261.8±52.5Bq/kg, 9.6±1.2Bq/kg and 8.7±1.0Bq/kg (Ofada); 257.3±39.0Bq/kg, 9.3±1.1Bq/kg and 7.8±1.8Bq/kg (Abakaliki); and 248.2±54.8Bq/kg, 9.3±0.9Bq/kg and 7.6±1.5Bq/kg (Aramoko). The respective mean 40K, 238U and 232Th activity concentrations in the soils were 333.9±62.8Bq/kg, 11.1±1.1Bq/kg and 11.0±1.4Bq/kg (Ofada); 306.8±36.0Bq/kg, 10.7±0.8Bq/kg and 9.4±1.8 Bq/kg (Abakaliki) and 321.8±42.4Bq/kg, 10.9±0.5Bq/kg and 9.5±0.6Bq/kg (Aramoko). The highest mean ingestion dose of 106.0±8.0µSv/y and outdoor effective dose of 32.4±3.40µSv/y were recorded in Ofada community. The highest mean ingestion cancer risk of (0.33±0.004) x10-3was recorded in Aramoko. The results indicated significantly lower radionuclide ingestion dose than the world limit value of 290µSv/y and lower cancer risks than the UNSCEAR recommended limit of 0.29x10-3, therefore consumption of ofada rice from the areas may not pose any serious health impact.

Texte intégralRésumé :
Polyphenol-rich plant extracts might alleviate the negative impact of oxidative stress and inflammation, but careful phytochemical standardisation and evaluation of various mechanisms are required to fully understand their effects. In this context, flower extracts of Sorbus aucuparia L.—a traditional medicinal plant—were investigated in the present work. The LC-MS/MS profiling of the extracts, obtained by fractionated extraction, led to the identification of 66 constituents, mostly flavonols (quercetin and sexangularetin glycosides with dominating isoquercitrin), pseudodepsides of quinic and shikimic acids (prevailing isomers of chlorogenic acid and cynarin), and flavanols (catechins and proanthocyanidins). Minor extract components of possible chemotaxonomic value were flavalignans (cinchonain I isomers) and phenylamides (spermidine derivatives). As assessed by HPLC-PDA and UV-spectrophotometric studies, the extracts were polyphenol-abundant, with the contents up to 597.6 mg/g dry weight (dw), 333.9 mg/g dw, 382.0 mg/g dw, and 169.0 mg/g dw of total phenolics, flavonoids, proanthocyanidins, and caffeoylquinic acids, respectively. Their biological in vitro effects were phenolic-dependent and the strongest for diethyl ether, ethyl acetate, and n-butanol fractions of the methanol-water (7 : 3, v/v) extract. The extracts showed significant, concentration-dependent ability to scavenge in vivo-relevant radical/oxidant agents (O2∙−, OH∙, H2O2, ONOO–, NO∙, and HClO) with the strongest effects towards OH∙, ONOO–, HClO, and O2∙− (compared to ascorbic acid). Moreover, the extracts efficiently inhibited lipoxygenase and hyaluronidase (compared to indomethacin) but were inactive towards xanthine oxidase. At in vivo-relevant levels (1-5 μg/mL), they also effectively protected human plasma components (proteins and lipids) against ONOO–-induced oxidative damage (reduced the levels of 3-nitrotyrosine, lipid hydroperoxides, and thiobarbituric acid-reactive substances) and normalised/enhanced the total nonenzymatic antioxidant capacity of plasma. In cytotoxicity tests, the extracts did not affect the viability of human PBMCs and might be regarded as safe. The results support the application of the extracts in the treatment of oxidative stress-related pathologies cross-linked with inflammatory changes.

Texte intégralRésumé :
Abstract Background Pituitary cysts (PCs) may be related to the development of diminished growth hormone secretion because they may limit the proliferation of somatotrophs. This study seeks to investigate the mass effect of PCs on the pituitary function. Methods Patients aged 6-18 with cysts and follow-ups between 2007–21 were compared to normal controls (NCs) aged 6-18 from a neuroradiology center. Pituitary volume (PV) is the volume of the pituitary gland including the cyst, while net pituitary volume (netPV) is the volume of the pituitary gland excluding the cyst. Since NCs did not have PCs, only PV was utilized. PVs and netPVs are reported in mm3. Data were stratified into prepubertal (age < 11 yrs) and pubertal (age > 11 yrs). The Kruskal-Wallis One Way ANOVA on Ranks was utilized to compare multiple means, and the Kruskal-Wallis Multiple-Comparison Z Value test (with Bonferroni adjustment) was utilized for pairwise comparisons. Results The mean and median PVs of prepubertal GHD (n=37), ISS (n=5), and NCs (n=58) were 290.2 ± 109.7 and 305.0, 314.4 ± 100.8 and 299.8, and 246.8 ± 63.7 and 241.6, respectively. The difference between mean PVs of prepubertal GHD, ISS, and NCs was not significant. The mean and median PVs of pubertal GHD (n=58), ISS (n=33), and NCs (n=112) were 391.5 ± 163.5 and 370.2, 409.2 ± 215.8 and 382.9, and 424.2 ± 138.9 and 402.7, respectively. The difference between mean PVs of pubertal GHD, ISS, and NCs was not significant. For netPV, the mean and median values for prepubertal GHD and ISS patients were 252.2 ± 83.3 and 272.2, and 245.2 ± 85.7 and 244.9, respectively. The difference between mean netPVs of prepubertal GHD, ISS, and NCs was not significant. For netPV, the mean and median values for pubertal GHD and ISS patients were 332.7 ± 121.3 and 346.4, and 333.9 ± 146.1 and 330.7, respectively. The mean netPVs of pubertal GHD and ISS patients were both significantly lower than the mean PV of pubertal NCs. The mean and median PVs for cyst patients were 364.8 ± 170.0 and 347.8 which was not significantly different from the NCs. The mean and median netPVs for cyst patients were 307.3 ± 122.9 and 289.0 which was significantly different from the NCs (p<0.001). Conclusion When considering the functional component of the pituitary gland, cyst volume should be subtracted from the overall pituitary gland. Presentation: Sunday, June 12, 2022 12:36 p.m. - 12:41 p.m., Monday, June 13, 2022 12:30 p.m. - 2:30 p.m.

Texte intégralRésumé :
Macroalgae have evolved different strategies to mitigate the damaging effects of solar ultraviolet radiation (UVR), including accumulation of photoprotective compounds such as mycosporine-like amino acids (MAAs). MAAs are secondary metabolites, synthesized by a large variety of organisms including macroalgae, phytoplanktons, cyanobacteria, lichen, fungi and some marine animals. MAAs act as photoprotectants and antioxidants. In the present investigation, MAAs profile of methanolic extracts of two marine red algae Gelidium sp. and Ceramium sp., collected from their natural environment, was studied. High-performance liquid chromatography (HPLC) and UV-Vis spectrometry analyses were used to reveal different MAAs profile in the extracts obtained from these two red algae. The MAAs isolated by HPLC were identified as shinorine (λmax= 333.5 nm), porphyra-334 (λmax=332.3 nm) and palythine (λmax=317.9 nm) having retention times (RT) 1.26, 2.12 and 3.64 min, respectively, in the extract obtained from Gelidium sp. Similarly, shinorine (λmax=332.3 nm), porphyra-334 (λmax=333.5 nm) and palythinol (λmax=332.5 nm) with RT 1.27, 2.13 and 4.61 min, respectively, were identified in the extract obtained from Ceramium sp. This study revealed that Gelidium sp. and Ceramium sp. could serve as potential source for economical exploration of MAAs in pharmaceutical sciences.Int. J. Appl. Sci. Biotechnol. Vol 5(1): 12-21

Texte intégralRésumé :
Summary The diffusing capacity for carbon monoxide (dlco) and the functional residual capacity (frc) of the lung were measured in 5 healthy Thoroughbreds before and after instillation of autologous blood into their lungs, in an attempt to develop a method to quantitate extravascular blood in the lungs of horses with exercise-induced pulmonary hemorrhage. Mean (± SD) baseline values of dlco and frc were 333.8 ± 61.9 ml/min/mm of Hg and 21.464 ± 4.156 L, respectively. Blood instillation resulted in decreases in dlco and frc. The paradoxic decrease in dlco (we were expecting to find an increase owing to blood in the airspaces, as has been reported in people) appears to be associated with the bronchoscopic procedure and with presence of blood in the airways. We concluded that rebreathing dlco measurements were not effective for detecting blood introduced bronchoscopically into the lungs of horses.

Texte intégralRésumé :
India is the second largest populous country in the world and more than half of its population lives in rural areas. This leads to widespread unemployment, low standard of living, inadequate productive skills and malnutrition in the country. In the developing countries especially like India, rural development is always been an important issue related to country’s economic progress. The rural development programmes are the key devices for the development of the rural areas in the country. As we know that, the people of rural area have seen difficulties from the time immemorial, the time has come to give them their deserving rights. India cannot shine without the shinning of the Rural India. National Development is almost synonymous with the Rural Development. This paper makes an attempt to measure actual performance and Government’s initiatives to accelerate the process of rural development through rural development programme in India and would be dealing with the changing life of the vulnerable people. The study reveals that the target number of houses to be constructed by the year 2021–2022, is 2.95 crore. The target set is to be achieved in phases and in the 1st phase 1 crore houses have been taken up for construction and in the 2nd phase 1.95 crore houses are being taken up for construction. 35.27 lakh houses have been constructed during 2020–2021 under Pradhan Mantri Awaas Yojana (PMAY-G) scheme. The pace of construction of PMGSY roads a nine years high of 135 kms per day in 2018–2019 as against an average of 73 kms during the period 2011 to 2014. Hence, the pace of construction has increased by 93%. Under PMGSY about 6, 26,910 Km road length completed where as 41000 Km road length constructed by using green technology and 14312 Km road length constructed by using plastic waste. MGNREGA has provided employment to 6.9 crore households by generating more than 305.71 crore person-days of wage employment covering 74.74 lakh works during financial year 2020–2021 and 5 crore works completed since inception. During COVID-19 pandemic, migrant workers were allowed to work under the scheme by being applying for job card. Approximately 1.44 crore Job Cards have been issued in FY 2020–2021. Total person-days generated in FY 2020–2021 have been 305.71 crore against approved LB for FY 2020–2021 of 333.09 crore. There has been 47% increase in person-days generated in comparison to FY 2019–2020. Further, the paper will give an idea how it will be beneficial for our country and how this little effort to rebuild the rural life and livelihood will make our country from developing to the developed country.
