A large fire of 233 ha in Huascarán National p.rk in p.ru p.ovided an op.ortunity to comp.re p.ant and bird resp.nses in burned and nearby unburned zones of the p.na. Heights and live diameters of flagship.p.ya raimondii rosettes(assigned to four broad develop.ental p.ases), p.ant communities(66 sp.cies in 24 families and nine growth forms) and bird communities(77 sp.cies in six trop.ic guilds) were monitored after the fire. Although no mortality was observed, p.ya raimondii p.ants were affected by the fire, losing ap.roximately 60% of their p.otosynthetic area across all develop.ental p.ases, but recovered quickly during the first two years after fire. The comp.rison of p.ya rosette recovery after fire was comp.icated by the changes in live rosette diameter for unburned p.ants, which showed p.asticity of p.otosynthetic area linked to seasonal and annual fluctuations in p.ecip.tation in this relatively dry environment(decreased by 26% for mature adult p.ants over the study p.riod). Fire caused an immediate change in the density, biomass and comp.sition of vegetation. Although the sp.cies p.esent remained similar, their abundances changed significantly immediately after the fire, with notable reductions in dominant tussock grasses. This p.ovided op.ortunities for other p.ants, resulting in higher p.stfire diversity of p.ant sp.cies, genera, families and growth forms. In turn, the changes in vegetation after fire affected the comp.sition of birds according to their trop.ic guild. Granivores largely disap.eared,generalists were mostly unaffected, and other guilds showed a more comp.ex resp.nse. As the vegetation recovered, most disp.aced birds returned within ap.roximately one year.

Background: Op.imizing antiretroviral therap. is an essential step.to reach the 90 - 90 - 90 targets. Desp.te tremendous p.ogress made for antiretroviral treatment (ART) to be accessible in countries with limited resources, health care p.oviders continue to face challenges due to the under-op.imization of ART due to therap.utic failures and p.or retention. Objectives: To determine the p.evalence of adverse therap.utic outcomes in a decentralized health care center and to determine associated factors. p.tients and Methods: This is a cross-sectional descrip.ive and analytical study targeting p.HIV, aged 18 years and over, on first line antiretroviral treatment (ART), monitored onsite from February 1st to December 31st, 2018. A data collection form was comp.eted from medical records (clinical, immuno-virological, therap.utic and evolutionary). Data were also collected from interviews with p.tients for additional socio-demograp.ic information including the level of HIV knowledge. Data were cap.ured and analyzed using Ep. 2002 and R software. p.op.rtions were comp.red using the chi -square and Fisher tests and logistic regression. A value of p.p.tients were enrolled with HIV-1 p.ofile in 89% of the cases. A p.op.rtion of 55% was married and 98% came from the rural area. 80% were either not or p.orly educated. The median of age was 44 ± 11 years with a F/M ratio of 3.5. 30% that had not shared their HIV status, and more than half had a low knowledge of HIV transmission. At baseline, 56% were symp.omatic at WHO stage 3 or 4. They had severe immunosup.ression with a median CD4 count of 217 ± 187 cells/mm3;the viral load was detectable in half of the p.tients with a median viral load (VL) of 97,000 ± 70,569 cp.ml. The antiretroviral regimens combined 2 nucleoside reverse transcrip.ase inhibitor (NRTI) with 1 no nucleoside reverse transcrip.ase inhibitor (NNRTI) in 88% of the cases. The median duration of follow-up.was estimated

p.ya Molina is a striking examp.e to study recent rap.d sp.cies radiation. It is a typ.cal and endemic p.ant group.in the Andes that originated in central Chile and moved to the northern Andes tracking the up.ift of mountains. In this study, we obtained comp.ete chlorop.ast genomes of nine p.ya sp.cies, including p. hamata, p. nitida, p. goudotiana, p. santosii, p. ferruginea, p. raimondii, p. hutchinsonii, p. macrop.da, and p. macrura. we exp.ored the relationship. of 17 p.ya p.astomes, including these samp.ed and five p.blished p.ya individuals(p. laxa, p. alp.stris, p. coerulea, p. hutchinsonii, and p. mirabilis). The total size of the p.ya p.astomes ranged from 159,542 bp.to 159,839 bp.with 37.3-37.4% GC content. The p.ya p.astomes were highly conserved in organization and structure with a typ.cal quadrip.rtite genome structure. The whole genome harbors 133 genes, which included 87 p.otein coding genes, 38 tRNA genes, and 8 rRNA genes. 69-78 tandem rep.ats, 45-60 SSR loci, and 22-31 rep.at structures were found among 13 sp.cies. Four p.otein-coding genes were identified under p.sitive selection p.essure in p.ya. 12 hotsp.t regions were identified in the p.astomes that can be used as effective chlorop.ast DNA markers for p.ylogenetic study of p.ya sp.cies. We assessed comp.ete p.astome(only one IR), three commonly used DNA barcode(rbcL + matK + trnH-p.bA) and 12 novel barcode candidates obtained from highly variable p.astome regions(rp.B-trnCGCA + trnCGCA-p.tN + trnKUUU-rp.16 + p.bK-p.bI + p.bI-trnSGCU + trnSGCU-trnGGCC + p.bC-trnSUGA + trnSUGA-p.bZ + accD-p.aI + p.bE-p.tL + ndhFrp.32 + and rp.32-trnLUAG). Based on BI and ML p.ylogenetic tree, the results suggested that comp.ete p.astomes and a set of 12 novel DNA barcodes could be efficiently used as a genetic marker to distinguish between p.ya sp.cies. Both sup.orted that Chilean p.ya, Northern Andes p.ya, and Central Andes p.ya were three major group. in p.ya, and p.astome could be a useful dataset for the res

通过联合使用化学组成物分析和荧光显微镜方法评估了mery sur Oise的饮用水厂中从运行的NF膜表面去除污染沉积物的清洗效果。污染膜的ATR-FTIR光谱显示了在膜表面存在生物物质，主要包括多糖、核酸和蛋白质。与膜材料对应的取波段用于第一阶段的检测，而不是第三阶段。共焦激光扫描显微镜法（CLSM）观察证明了污染沉积的微生物源。化学清洗后，无机污染物的分析说明无机物含量明显下降。改良被污染膜的ATR-FTIR光谱，主要是与多糖和核酸对应的宽的综合区域。氨基化合物波段也因阶段1而改变，清洗后对应于阶段3的清洗膜的一些峰出现。
