Synovial macrophages are crucial in the development of joint inflammation and bone damage; however, the pathways that control macrophage remodeling in inflammatory M1 cells or bone-eroding osteoclasts are not fully understood. We determined that elevated IL-7R/CD127 expression is the hallmark of rheumatoid arthritis (RA) M1 macrophages and that these cells are highly responsive to interleukin-7 (IL-7)-driven osteoclastogenesis. We established that lipopolysaccharide (LPS), interferon-γ (IFNγ), and tumor necrosis factor-α (TNFα), the classic M1 macrophage mediators, enhance IL-7R expression in RA and murine macrophages.

The frequency and genotype diversity of aMPV in Turkish broiler flocks is not known at present. The aim of this study was to report the first molecular identification and phylogeny of aMPV, which is circulating in Turkish broiler flocks.

Here, we investigate whether accumulation of infection/injury-induced CCSCs due to impaired autophagy influences colon cancer development and progression. When mice were infected with (CR; 10CFUs), we discovered presence of autophagosomes with increases in Beclin-1, LC3B and p62 staining during crypt hyperplasia.

CELF2 is an RNA binding protein that modulates mRNA stability and translation. Since IR induces autophagy, we hypothesized that CELF2 regulates autophagy-mediated colorectal cancer (CRC) cell death.

Commercial bCPAP brands are expensive in Nigeria and this has driven Nigerian paediatricians to use potentially risky improvised devices (IbCPAP). : This study aimed to design, produce and trial an appropriate low-cost bCPAP machine which is functionally effective and safe.

Primary BAs play critical roles in cholesterol metabolism, lipid digestion, and host⁻microbe interaction. Although BAs are reabsorbed via enterohepatic circulation, primary BAs serve as substrates for bacterial biotransformation to secondary BAs in the colon.

Management of GERD is individualized for each patient depending on severity of symptoms, complications of GERD and patient/physician preference. The different management options include life style modification, pharmacological therapy, minimally invasive procedures and surgery.

Nocturnal GERD symptoms may be associated with sleep disturbances, which in turn can drastically affect well-being and fatigue levels. We hypothesized that GERD symptoms would be associated with poorer sleep in patients with SSc.

A dearth of preclinical models that recapitulate the metastatic microenvironment has impeded the development of therapeutic agents that are effective against metastatic disease. Because the majority of solid tumors metastasize to the lung, we developed a multicellular lung organoid that mimics the lung microenvironment with air sac-like structures and production of lung surfactant protein.

Objective: To evaluate a project that integrated essential primary health-care services into the oral polio vaccine programme in hard-to-reach, underserved communities in northern Nigeria.
Methods: In 2013, Nigeria's polio emergency operation centre adopted a new approach to rapidly raise polio immunity and reduce newborn, child and maternal morbidity and mortality. We identified, trained and equipped eighty-four mobile health teams to provide free vaccination and primary-care services in 3176 hard-to-reach settlements.
Background: Nomadic populations have a considerably higher risk of contracting a number of diseases but, despite the magnitude of the public health risks involved, they are mostly underserved with few health policies or plans to target them. Nomadic population movements are shown to be a niche for the transmission of diseases, including poliomyelitis. The nomadic routes traverse the northern states of Nigeria to other countries in the Lake Chad subregion.

Aims: Evaluate the outcomes of gastrointestinal endoscopy (GIE) in patients hospitalized with AIS and GIH.
Purpose Of Review: The trillions of microbes collectively referred to as the human microbiota, inhabit the human body and establish a beneficial relationship with the host. It is clear however that dysbiosis impacting microbial diversity in the gut, may lead to development of inflammatory and malignant gastrointestinal diseases including colorectal cancer (CRC). We provide a literature review of the recent influx of information related to the alterations in gut microbiota composition that influences CRC incidence and progression.

We showed previously that Citrobacter rodentium (CR)-induced colonic crypt hyperplasia and/or colitis is regulated by a functional cross-talk between the Notch and Wnt/β-catenin pathways. In the current study, mucus analysis in the colons of CR-infected (108 CFUs) and Notch blocker Dibenzazepine (DBZ, i.

Since most of the biological actions of E2 are mediated through the classical estrogen receptors alpha (ERα) and/or beta (ERβ), and both these receptors are present in the heart, we examined the role of ERα and ERβ in the rescue action of E2 against HF.
Methods: Severe HF was induced in male mice by transverse aortic constriction-induced pressure overload.
Avian avulaviruses serotype 1 (abbreviated as APMV-1 for the historical name avian paramyxovirus 1) are capable of infecting a wide spectrum of avian species with variable clinical symptoms and outcomes. Ease of transmission has allowed the virus to spread worldwide with varying degrees of virulence depending upon the virus strain and host species. The emergence of new virulent genotypes from global epizootics, and the year-to-year genomic changes in low and high virulence APMV-1 imply that distinct genotypes of APMV-1 are simultaneously evolving at different geographic locations across the globe.

However, audit and feedback tools can only be effective if the targeted health professionals access and actively review their data. Email is used by Cancer Care Ontario, a provincial cancer agency, to promote access to a Web-based audit and feedback tool called the Screening Activity Report (SAR); however, current emails that lack behavior change content have been ineffective at encouraging log-in to the SAR.
