The gut microbiota in chicken has long been studied, mostly from the perspective of growth performance. However, there are some immunological studies regarding gut homeostasis in chicken. Although CD4+ CD25+ T cells are reported to act as regulatory T cells (Tregs) in chicken, there have been no studies showing the relationship between gut microbiota and Tregs. Therefore, we established a model for 'antibiotics (ABX)-treated chickens' through administration of an antibiotic cocktail consisting of ampicillin, gentamycin, neomycin, metronidazole, and vancomycin in water for 7 days...

Theories of cross-linguistic phonetic category perception posit that listeners perceive foreign sounds by mapping them onto their native phonetic categories, but, until now, no way to effectively implement this mapping has been proposed. In this paper, Automatic Speech Recognition systems trained on continuous speech corpora are used to provide a fully specified mapping between foreign sounds and native categories. The authors show how the machine ABX evaluation method can be used to compare predictions from the resulting quantitative models with empirically attested effects in human cross-linguistic phonetic category perception...

BACKGROUND: Parenteral nutrition (PN) leads to decreased production of Paneth cell-derived antimicrobial peptides and is accompanied by dysbiosis of the gut. The role of gut microbiota in regulating Paneth cell function during PN is unknown. METHODS: Male C57BL/6 mice received either an antibiotic cocktail (Abx) or nothing (Normal) in their drinking water for 2 weeks before being fed either standard laboratory chow (Abx-Chow and Normal-Chow) or a continuous infusion of PN solution (Abx-PN and Normal-PN) for 7 days...

Inflammation in chronic obstructive pulmonary disease (COPD) is often corticosteroid resistant and, thus, alternative anti-inflammatory approaches are needed. Since it is still not clear whether blocking specific pro-inflammatory factors may provide clinical benefit in COPD, we have performed a meta-analysis to quantify the impact of monoclonal antibodies (mABs) targeting the cytokine/chemokine-mediated inflammation in COPD. A pairwise and network meta-analyses were performed by extracting data from randomized clicnial trials on COPD concerning the impact of mABs vs...

Although the outcome of flavivirus infection can vary from asymptomatic to lethal, environmental factors modulating disease severity are poorly defined. Here, we observed increased susceptibility of mice to severe West Nile (WNV), Dengue, and Zika virus infections after treatment with oral antibiotics (Abx) that depleted the gut microbiota. Abx treatment impaired the development of optimal T cell responses, with decreased levels of WNV-specific CD8+ T cells associated with increased infection and immunopathology...

Cardiac implantable electronic device (CIED) infections are associated with significant morbidity in the pediatric device population, with a tenfold higher risk of infection in children compared to adults. The 2010 American Heart Association (AHA) guidelines recommend a single dose of systemic antibiotic (ABX) prophylaxis prior to CIED implantation and no post-operative (OP) ABX. However, there is limited data regarding adherence to this recommendation among the pediatric community. To assess current clinical practices for CIED ABX prophylaxis in pediatrics; whether the AHA guidelines are being followed; and if not, the reasons for non-adherence...

Organic-inorganic hybrid perovskites, with the formula ABX3 (A=organic cation, B=metal cation, and X=halide; for example, CH3 NH3 PbI3 ), have diverse and intriguing physical properties, such as semiconduction, phase transitions, and optical properties. Herein, a new ABX3 -type semiconducting perovskite-like hybrid, (hexamethyleneimine)PbBr3 (1), consisting of one-dimensional inorganic frameworks and cyclic organic cations, is reported. Notably, the inorganic moiety of 1 adopts a perovskite-like architecture and forms infinite columns composed of face-sharing PbBr6 octahedra...

Background & objectives: : Immune complexes (ICs) play a crucial role which can either be beneficial or pathological to the host. Involvement of circulating immune complexes (CICs) has been shown in tuberculosis (TB) cases (adults and neonates form), but its immunomodulatory effect has not been studied in vivo. Hence, this study was carried out to understand and explore the prognostic therapeutic potential of CICs on the host immune system in guinea pigs animal TB model. Methods: In this study, the guinea pigs (group I) were immunized with in vitro synthesized antigen excess IC (AgX-IC), group II with antibody excess IC (AbX-IC) and group III with phosphate-buffered saline...

Peptidoglycan recognition proteins (PGRPs) and commensal microbes mediate pathogen infection outcomes in insect disease vectors. Although PGRP-LD is retained in multiple vectors, its role in host defense remains elusive. Here we report that Anopheles stephensi PGRP-LD protects the vector from malaria parasite infection by regulating gut homeostasis. Specifically, knock down of PGRP-LD (dsLD) increased susceptibility to Plasmodium berghei infection, decreased the abundance of gut microbiota and changed their spatial distribution...

BACKGROUND: Atopic dermatitis (AD) is primarily treated with topical therapies, systemic immunosuppressants, or adjunctive therapies. OBJECTIVE: As novel treatment approaches for AD emerge, we characterize AD treatment and examine trends in treatment over time. METHODS: Visits for AD were identified in the 2003-2012 National Ambulatory Medical Care Survey (NAMCS). We identified topical corticosteroids (TCS), antibiotics (Abx), antihistamines (AH), topical calcineurin inhibitors (TCI), and systemic immunosuppressants (SI) prescribed at AD visits...

Vitamin D, 25hydroxyvitamin D (25D), and 24,25dihydroxyvitamin D (24,25D) were measured before and after broad spectrum antibiotic (Abx) treatment for 2 wks. Abx treatments increased 25D and 24,25D levels suggesting that the microbiota or Abx were altering vitamin D metabolism. Increased 25D, but not 24,25D, following Abx treatments were found to be dependent on toll like receptor signaling. Conversely, the effects of Abx on 24,25D levels required that the vitamin D receptor (VDR) be expressed in tissues outside of the hematopoietic system (kidney) and not the immune system...
