AGD also did not correlate overall with mean fecal androgen metabolites in MMUs. However, AGD was correlated with dominance rank in MMUs, demonstrating that higher-ranking males in these multimale units had longer AGDs. Body size did not show the same relationship with dominance rank, suggesting that male rank was not just a reflection of absolute male size. Our findings indicate that AGD predicts male competitive ability in this species and that it may be a useful correlate throughout the non-human primates. These results also support the idea that prenatal androgen exposure increases the likelihood of the expression of behaviors that maintain high dominance rank. © 2020 Wiley Periodicals, Inc.Citizen science-based research has been used effectively to estimate animal abundance and breeding patterns, to monitor animal movement, and for biodiversity conservation and education. Here, we evaluate the feasibility of using social media observations to assess the distribution of small apes in Peninsular Malaysia. We searched for reports of small ape observations in Peninsular Malaysia on social media (e.g., blogs, Facebook, Instagram, Twitter, YouTube, iNaturalist, etc.), and also used online, radio, print messaging, and word of mouth to invite citizen scientists such as birders, amateur naturalists, hikers, and other members of the public to provide information about small ape observations made during their activities. These reports provided new information about the occurrence of all three species of small apes (Hylobates agilis, Hylobates lar, and Symphalangus syndactylus) in Peninsular Malaysia. Social media users reported observations of small apes in almost every state. Despite the fact that small cals, Inc.CXXC5 is a member of the CXXC-type zinc finger epigenetic regulators. Various hematopoietic and nonhematopoietic roles have been assigned to CXXC5. In the present study, the role of Cxxc5 in myelopoiesis was studied using overexpression and short hairpin RNA-mediated knockdown in mouse early stem and progenitor cells defined as Lineage- Sca-1+ c-Kit+ (LSK) cells. Knockdown of Cxxc5 in mouse progenitor cells reduced monocyte and increased granulocyte development in ex vivo culture systems. In addition, ex vivo differentiation and proliferation experiments demonstrated that the expression of Cxxc5 affects the cell cycle in stem/progenitor cells and myeloid cells. Flow cytometry-based analyses revealed that down-regulation of Cxxc5 leads to an increase in the percentage of cells in the S phase, whereas overexpression results in a decrease in the percentage of cells in the S phase. Progenitor cells proliferate more after Cxxc5 knockdown, and RNA sequencing of LSK cells, and single-cell RNA sequencing of differentiating myeloid cells showed up-regulation of genes involved in the regulation of cell cycle after Cxxc5 knockdown. These results provide novel insights into the physiologic function of Cxxc5 during hematopoiesis, and demonstrate for the first time that it plays a role in monocyte development. ©2020 Society for Leukocyte Biology.Enzyme replacement therapy (ERT) with recombinant α-galactosidase A (r-αGAL A) for the treatment of Fabry disease has been available for over 15 years. Long-term treatment may slow down disease progression, but cardiac, renal, and cerebral complications still develop in most patients. In addition, lifelong intravenous treatment is burdensome. Therefore, several new treatment approaches have been explored over the past decade. Chaperone therapy (Migalastat; 1-deoxygalactonojirimycin) is the only other currently approved therapy for Fabry disease. This oral small molecule aims to improve enzyme activity of mutated α-galactosidase A and can only be used in patients with specific mutations. Treatments currently under evaluation in (pre)clinical trials are second generation enzyme replacement therapies (Pegunigalsidase-alfa, Moss-aGal), substrate reduction therapies (Venglustat and Lucerastat), mRNA- and gene-based therapy. This review summarises the knowledge on currently available and potential future options for the treatment of Fabry disease. © 2020 The Authors.

More recently, NTBC has been used to halt homogentisic acid accumulation in alkaptonuria (AKU) with evidence suggesting its efficacy as a disease modifying agent. [https://www.selleckchem.com/products/Trichostatin-A.html read more] NTBC-induced hypertyrosinaemia has been associated with cognitive impairment and potentially sight-threatening keratopathy. In the context of a non-lethal condition (ie, AKU), these serious risks call for an evaluation of the wider impact of NTBC on the tyrosine pathway. We hypothesised that NTBC increases the tyrosine pool size and concentrations in tissues. In AKU mice tyrosine concentrations of tissue homogenates were measured before and after treatment with NTBC. In humans, pulse injection with l-[13 C9 ]tyrosine and l-[d8 ]phenylalanine was used along with compartmental modelling to estimate the size of tyrosine pools before and after treatment with NTBC. We found that NTBC increased tyrosine concentrations in murine tissues by five to nine folds. It also significantly increased the tyrosine pool size in humans (P  less then  .001), suggesting that NTBC increases tyrosine not just in serum but also in tissues (ie, acquired tyrosinosis). This study provides, for the first time, the experimental proof for the magnitude of NTBC-related acquired tyrosinosis which should be overcome to ensure the safe use of NTBC in AKU. © 2020 SSIEM.Last December 2019, a new virus, named novel Coronavirus (COVID-2019) causing many cases of severe pneumonia was reported in Wuhan, China. The virus knowledge is limited and especially about COVID-2019 pathogenesis. The Open Reading Frame 1ab (ORF1ab) of COVID-2019 has been analyzed to evidence the presence of mutation caused by selective pressure on the virus. For selective pressure analysis fast-unconstrained Bayesian approximation (FUBAR) was used. Homology modelling has been performed by SwissModel and HHPred servers. The presence of transmembrane helical segments in Coronavirus ORF1ab non structural protein 2 (nsp2) and nsp3 was tested by TMHMM, MEMSAT, and MEMPACK tools. Three-dimensional structures have been analyzed and displayed using PyMOL. FUBAR analysis revealed the presence of potential sites under positive selective pressure (P  less then  .05). Position 723 in the COVID-2019 has a serine instead a glycine residue, while at aminoacidic position 1010 a proline instead an isoleucine. Significant (P  less then  .05) pervasive negative selection in 2416 sites (55%) was found. The positive selective pressure could account for some clinical features of this virus compared with severe acute respiratory syndrome (SARS) and Bat SARS-like CoV. The stabilizing mutation falling in the endosome-associated-protein-like domain of the nsp2 protein could account for COVID-2019 high ability of contagious, while the destabilizing mutation in nsp3 proteins could suggest a potential mechanism differentiating COVID-2019 from SARS. These data could be helpful for further investigation aimed to identify potential therapeutic targets or vaccine strategy, especially in the actual moment when the epidemic is ongoing and the scientific community is trying to enrich knowledge about this new viral pathogen. © 2020 Wiley Periodicals, Inc.BACKGROUND AND AIM The aim of this study was to identify factors affecting persistent gastric regenerating atypia and determine the effect of Helicobacter pylori eradication on the course of this lesion. METHODS In cross-sectional setting, comprehensive health check-up subjects who underwent both endoscopy and H.&nbsp;pylori test from 2001 to 2009 were included. The association between H.&nbsp;pylori and gastric regenerating atypia was evaluated. In cohort setting, patients with regenerating atypia who underwent H.&nbsp;pylori test from 2001 to 2013 were included. Factors affecting positive pathology (persistent regenerating atypia or new development of neoplasm) in patients with regenerating atypia at baseline were investigated. RESULTS In cross-sectional setting, regenerating atypia was observed in 1.1% (241/22&nbsp;133). H.&nbsp;pylori infection was associated with gastric regenerating atypia (adjusted odds ratio, 1.47; 95% confidence interval [CI], 1.12-1.91). In cohort setting, 310 patients with regenerating atypia were finally eligible. Positive pathology rate during follow up was 16.1% (15/93) in the persistent infection group, 2.8% (3/106) in successful eradication group, and 4.5% (5/111) in baseline H.&nbsp;pylori-negative group. Persistent H.&nbsp;pylori infection increased the risk of positive pathology (adjusted risk ratio [RR], 7.18; 95% CI, 1.95-26.48) compared to H.&nbsp;pylori eradication group. Persistent H.&nbsp;pylori infection increased the risk of regenerative atypia (adjusted RR, 5.70; 95% CI, 1.46-22.17) and new neoplasm (adjusted RR, 10.74; 95% CI, 1.10-105.17) compared to baseline negative H.&nbsp;pylori. CONCLUSIONS H.&nbsp;pylori infection is an independent risk factor for gastric regenerating atypia. Eradication of H.&nbsp;pylori seems helpful for regression of regenerating atypia. © 2020 Journal of Gastroenterology and Hepatology Foundation and John Wiley &amp; Sons Australia, Ltd.in English, Spanish ANTECEDENTES La cirugía antirreflujo (antireflux surgery, ARS) se realiza con frecuencia en niños, aunque la evidencia sobre su eficacia es limitada. Nos propusimos determinar la eficacia de la ARS con respecto a medidas objetivas de calidad de vida (quality of life, QoL) y la utilidad de las exploraciones del tracto gastrointestinal superior en niños con funciones neurológicas normales (neurologically normal, NN) y con discapacidad neurológica (neurologically impaired, NI). MÉTODOS Se llevó a cabo una revisión sistemática (de acuerdo con la normativa PRISMA) de artículos que describiesen series de niños sometidos a ARS en los que se realizaron pruebas objetivas preoperatorias y postoperatorias. Principalmente, se efectuó una búsqueda en EMBASE, CINAHL, Medline y Pubmed desde un comienzo hasta 04/19. La calidad de los artículos se evaluó siguiendo los criterios MINORS. RESULTADOS De 789 artículos, 14 reunían los criterios de elegibilidad - 12 estudios observacionales prospectivos y 2 estud NN y niños NI. A pesar de que la ARS es una cirugía electiva habitual, es llamativa la falta de evaluaciones preoperatorias y postoperatorias rigurosas en la mayoría de los estudios de pacientes.BACKGROUND Methods to identify patients at risk for incomplete physical recovery after intensive care unit (ICU) stay are lacking. Our aim was to develop a method for prediction of new-onset physical disability at ICU discharge. METHODS Multinational prospective cohort study in 10 general ICUs in Sweden, Denmark, and the Netherlands. Adult patients with an ICU stay&nbsp;≥12&nbsp;hours were eligible for inclusion. Sixteen candidate predictors were analyzed with logistic regression for associations with the primary outcome; new-onset physical disability 3&nbsp;months post-ICU, defined as a&nbsp;≥10 score reduction in the Barthel Index (BI) compared to baseline. RESULTS Of the 572 included patients, follow-up data are available on 78% of patients alive at follow-up. The incidence of new-onset physical disability was 19%. Univariable and multivariable modeling rendered one sole predictor for the outcome physical status at ICU discharge, assessed with the five first items of the Chelsea critical care physical assessment tool (CPAx) (odds ratio 0.
