Clinical and laboratory identification of the underlying risk of respiratory illness in athletes has proved problematic. The aim of this study was to determine whether clinical data, combined with immune responses to standardised exercise protocols and genetic cytokine polymorphism status, could identify the risk of respiratory illness (symptoms) in a cohort of highly-trained athletes. Male endurance athletes (n=16; VO2max 66.5 ± 5.1 mL.kg-1.min-1) underwent a clinical evaluation of known risk factors by a physician and comprehensive laboratory analysis of immune responses both at rest and after two cycling ergometer tests: 60 min at 65% VO2max (LONG); and 6 x 3 min intervals at 90% VO2max (INTENSE)...

The β-1, 3 (D)-glucan (β-glucan) present in the cell wall of Candida albicans induces epigenetic changes in human monocytes resulting in primed macrophages exhibiting increased cytokine responsiveness to reinfection. This phenomenon is referred to as trained immunity or innate immune memory. However, whether β-glucan can reprogram murine monocytes in vitro or induce lasting effects in vivo has yet to be elucidated. Thus purified murine spleen-derived monocytes were primed with β-glucan in vitro and assessed for markers of differentiation and survival...

Viral infections continuously challenge and shape our immune system. Due to their fine antigen recognition ability, adaptive lymphocytes protect against pathogen reencounter by generating specific immunological memory. Innate cells such as macrophages also adapt to pathogen challenge and mount resistance to reinfection, a phenomenon termed trained immunity. As part of the innate immunity, natural killer (NK) cells can display rapid effector functions and play a crucial role in the control of viral infections, especially by the β-herpesvirus cytomegalovirus (CMV)...

In the past, numerous methods have been developed to predict MHC class II binders or T-helper epitopes for designing the epitope-based vaccines against pathogens. In contrast, limited attempts have been made to develop methods for predicting T-helper epitopes/peptides that can induce a specific type of cytokine. This paper describes a method, developed for predicting interleukin-10 (IL-10) inducing peptides, a cytokine responsible for suppressing the immune system. All models were trained and tested on experimentally validated 394 IL-10 inducing and 848 non-inducing peptides...

BACKGROUND: Health literacy (HL) helps individuals to make effective use of available health services. In low-income countries such as Bangladesh, the less than optimum use of services could be due to low levels of HL. Bangladesh's health service delivery is pluralistic with a mix of public, private and informally trained healthcare providers. Emphasis on HL has been inadequate. Thus, it is important to assess the levels of HL and service utilization patterns. The findings from this study aim to bridge the knowledge gap...

BACKGROUND: People's participation in health, enshrined in the 1978 Alma Ata declaration, seeks to tap into community capability for better health and empowerment. One mechanism to promote participation in health is through participatory action research (PAR) methods. Beginning in 1994, the Bangladeshi research organization ICDDR,B implemented a project "self-help for health," to work with existing rural self-help organizations (SHOs). SHOs are organizations formed by villagers for their well-being through their own initiatives without external material help...

The promotion of change and growth within medical education is oftentimes the result of a complex mix of societal, cultural and economic forces. Graduate medical education in internal medicine is not immune to these forces. Several entities and organizations can be identified as having a major influence on internal medicine training and graduate medical education as a whole. We have reviewed how this is effectively accomplished through these entities and organizations. The result is a constantly changing and dynamic landscape for internal medicine training...

Acquired energetic resources allocated to a particular trait cannot then be re-allocated to a different trait. This often results in a trade-off between survival and reproduction for the adults of many species, but such a trade-off may be manifested differently in juveniles not yet capable of reproduction. Whereas adults may allocate resources to current and/or future reproduction, juveniles can only allocate to future reproduction. Thus, juveniles should allocate resources toward traits that increase survival and their chances of future reproductive success...

Sub-visible particles in therapeutic protein formulations are an increasing manufacturing and regulatory concern due to their potential to cause adverse immune responses. Flow imaging microscopy is used extensively to detect sub-visible particles and investigate product deviations, typically by comparing imaging data using histograms of particle descriptors. Such an approach discards much information, and requires effort to interpret differences, which is problematic when comparing many data sets. We propose to compare imaging data by using the Kullback-Leibler divergence, an information theoretic measure of the difference of distributions...

Although originally developed for predicting transfusion outcomes of serologically incompatible blood, the monocyte monolayer assay (MMA) is a highly versatile in vitro assay that can be modified to examine different aspects of antibody and Fcγ receptor (FcγR)-mediated phagocytosis in both research and clinical settings. The assay utilizes adherent monocytes from peripheral blood mononuclear cells isolated from mammalian whole blood. MMA has been described for use in both human and murine investigations. These monocytes express FcγRs (e...

Recent scientific advances have significantly contributed to our understanding of the complex connection between the microbiome and cancer. Our bodies are continuously exposed to microbial cells, both resident and transient, as well as their byproducts, including toxic metabolites. Circulation of toxic metabolites may contribute to cancer onset or progression at locations distant from where a particular microbe resides. Moreover, microbes may migrate to other locations in the human body and become associated with tumor development...

Activation of resident and infiltrating immune cells is a central event in training adaptation and other contexts of skeletal muscle repair and regeneration. A precise orchestration of inflammatory events in muscle fibers and immune cells is required after recurrent contraction-relaxation cycles. However, the mechanistic aspects of this important regulation remain largely unknown. We now demonstrate that besides a dominant role in controlling cellular metabolism, the peroxisome proliferator-activated receptor γ co-activator 1α (PGC-1α) also has a profound effect on cytokine expression in muscle tissue...

MOTIVATION: Somatic DNA recombination, the hallmark of vertebrate adaptive immunity, has the potential to generate a vast diversity of antigen receptor sequences. How this diversity captures antigen specificity remains incompletely understood. In this study we use high throughput sequencing to compare the global changes in T cell receptor β chain complementarity determining region 3 (CDR3β) sequences following immunization with ovalbumin administered with complete Freund's adjuvant (CFA) or CFA alone...

BACKGROUND AND OBJECTIVE: Epigenetics contributes to the outcome of chronic hepatitis B virus (HBV) infection. However, the role of methyl-CpG binding domain (MBD) family in the natural history of chronic hepatitis B (CHB) has not been demonstrated. It is aimed to investigate the dynamic expression of MBD family and assess the potential association of MBD family in the progression of CHB. METHODS: Quantitative real-time polymerase chain reaction (RT-PCR) was used to determine the mRNA levels of MBD family in peripheral blood mononuclear cells (PBMCs) from 223 patients with CHB as training cohort, 146 patients with CHB as validation cohort [immune-tolerant (IT), immune clearance (IC), non/low-replicative (LR) and HBeAg negative hepatitis (ENH)], and 14 healthy controls (HCs)...
