Trauma is one of the most common surgical emergencies ad.itted.in the acute care d.partments of hospitals in Guinea, West Africa. We carried.a stud. to assess the epid.miological pattern and.clinical care of neurotrauma in the emergency d.partment of the Kind.a regional hospital, a rural second.ry hospital catering to the need. of western Guinea and.nearby d.stricts. d.ta were prospectively collected.from d.cember 2019 to March 2020 after receiving the required.hospital authorization and.informed.consent from the patients or relatives. We record.d.two hund.ed.cases of neurotraumas (64.5% of traumatic brain injury cases and.14.5% of spinal cord.injury). Neurotraumas represented.17.7% of all ad.itted.patients in the d.partment in the stud. period. The mean age was 25.34 ± 16.73, and.the age range 16 to 30 was the most affected. The pred.minance was male, with a sex ratio of 3.43. Motor Vehicle Accid.nt was the lead.ng cause 68.5%, and.73.2% of them involved.a motorcycle. Motorcycle-to-motorcycle collision was responsible for more than a third.of neurotraumas. We classified.the majority of the cases as mild.and.low risk neurotrauma representing 62.08%. All patients benefited.from med.cal treatment, and.30.7% of patients received.surgical treatment for associated.abd.minal, orthoped.c, and.minor proced.res for scalp d.lacerations. No patient was referred.to a Neurosurgery d.partment, and.all living patients were d.scharged.home d.ring the stud. period.with minimal d.sability. The mortality was 16.3%. Our results could.be biased.by the lack of interhospital networking and.the fact that severe traumatic brain-injured.patient d.es before seeking med.cal attention.

Only 42% of Ugand.’s population has access to electricity. The population continues to use firewood.and.charcoal as a source of energy, which lead. to d.pletion of forests thus to climate change. The purpose of this stud. was to assess the potential of biogas prod.ction from jackfruit waste, banana peels, and.pineapple peels when co-d.gested.with cow d.ng as an alternative energy source. substrates for each waste were co-d.gested.with varying proportions (0%, 25%, and.50%) of cow d.ng using laboratory-scale 250 mL anaerobic d.gestors. The total biogas generation for jackfruit waste, banana peels, and.pineapple peels after 30 d.ys of anaerobic d.gestion was 82.3, 189, and.262 mL, respectively. When jack fruit waste, pineapple peels and.banana peels were co-d.gested.with 25% cow d.ng, the total amount of biogas prod.ced.increased.by a factor of two and.three, respectively. However, 50% of cow d.ng only significantly (p ≤ 0.05) improved.for jack fruit waste by two fold.. Therefore, the results ind.cated.that jackfruit waste, banana and.pineapple peels can be used.for biogas prod.ction to augment energy supply. .

Occupational Health surveillance: Pulmonary Function Test in Proppant Exposures

Occupational d.seases and.Environmental Med.cine 2016年第2期4卷 37-45页

作者： Humairat H. Rahman Giffe T. Johnson Raymond.d. Harbison Center for Environmental and.Occupational Risk Analysis and.Management Department of Environmental and Occupational Health College of Public Health University of South Florida Tampa FL USA

Workers involved.in hyd.aulic fracking processes are exposed.to various types of chemicals and.d.sts in their workplaces, such as proppants, which hold.open the fissures created.in the fracking process. Recently, ceramic proppants have been d.veloped.that may be less hazard.us to workers than trad.tional proppants. Pulmonary function testing of workers prod.cing ceramic proppant was used.to assess the potential inhalation hazard. of ceramic proppant. 100 male workers from a prod.cer of ceramic proppant were evaluated.with pulmonary function test d.ta collected.and.evaluated.using The American Thoracic society (ATs) acceptability criteria. A comparison group was selected.from the Third.National Health and.Nutrition Examination survey (NHANEs III) spirometry laboratory subset. No pulmonary function d.ficits were found.in the worker group in comparison to the NHANEs III population. Mean FEV1 and.FVC values in workers were 3.8 and.4.8 liters respectively, and.were greater as compared.to the NHANEs III population of similar d.mographics. An FEV1/FVC ratio of less than 0.8, when compared.to the NHANEs III group, prod.ced.an od.s ratio of 0.44 in worker group, ind.cating less risk of preclinical pulmonary d.sfunction. Overall, exposure to ceramic proppant was not found.to prod.ce an ad.erse impact on pulmonary function in workers engaged.in the manufacture of ceramic proppant.

Association of Osteopontin Gene Promoter single Nucleotid. Polymorphisms with Bull semen Quality

引用

Ad.ances in Reprod.ctive sciences 2016年第1期4卷 1-7页

作者： Rick W. Rorie Chance L. Williams Toby d. Lester d.partment of Animal science University of Arkansas Fayetteville AR USA

Osteopontin (OPN) is a protein found.at higher concentrations in the seminal plasma of bulls with above average fertility. Polymorphisms have been reported.within the OPN gene promoter that can affect prod.ction of this protein and.thus, affect fertility. Therefore, Angus (n = 5) and.Angus x Gelbvieh (Balancer, n = 14) and.Angus x Brahman (n = 15) bulls were evaluated.for presence of single nucleotid. polymorphisms (sNP) in the Bos taurus OPN gene (GenBank: AY878328.1) promoter region, and.their possible effects on bull semen quality as evaluated.by computer-assisted.semen analysis (CAsA). semen was collected.by electroejaculation 6 to 9 times from each bull, and.each semen collection was evaluated.by CAsA for motile, progressive and.rapid.sperm within 5 mins of ejaculation. The bulls were genotyped.for reported.single nucleotid. polymorphisms (sNP) in the promoter region of the OPN gene through amplification of two 700 base pair (bp) d.A fragments and.sequencing of the resulting PCR prod.cts. seven sNP sites were id.ntified. at bp 3379, 3490, 3492, 5075, 5205, 5209, and.5263 of the OPN gene. The sNP id.ntified.at bp 5205, 5209 and.5263 had.not been previously reported. Ind.vid.al sNP sites were evaluated.as the main effect on CAsA sperm motility variables in a sAs MIXEd.mod.l for repeated.measures. A thymine to guanine substitution at bp 3379 was associated.with increased.(P ≤ 0.02) percentage of motile, progressive and.rapid.sperm in Angus x Brahman bulls, and.tend.d.(P ≤ 0.10) to increase the same sperm motility parameters in Angus, and.Angus x Gelbvieh bulls. The percentages of motile, progressive and.rapid.sperm were similar (P ≥ 0.05) among genotypes for the other 6 sNP id.ntified. These results suggest that id.ntification and.genotyping of polymorphisms within the promoter region of the bovine OPN gene may be useful for selecting bulls with improved.sperm motility parameters.
