Commensal bacteria play an important role in formation of the immune system, but the mechanisms involved are incompletely understood. In this study, we analyze CD1d-restricted invariant NKT (iNKT) cells in germfree mice and in two colonies of C57BL/6 mice termed conventional flora and restricted flora (RF), stably bearing commensal microbial communities of diverse but distinct composition. In g...
We measured physiological functionalities, including antihypertensive angiotensin I-converting enzyme inhibitory activity and immun-stimulating β-glucan content for sixty kinds of Makgeolli that is commercially available from the market. As a result, we selected R-12 commercial raw Makgeolli, with a high content of immuno-stimulating β-glucan, and R-14 commercial raw Makgeolli, exhibiting high ...
Chronic inflammation associated with cigarette smoke fosters malignant transformation and tumor cell proliferation and promotes certain nonneoplastic pulmonary diseases. The question arises as to whether chronic inflammation and/or colonization of the airway can be attributed, at least in part, to tobacco-associated microbes (bacteria, fungi, and spores) and/or microbial toxins (endotoxins and ...
Life in desert soil is marked by episodic pulses of water and nutrients followed by long periods of drought. While the desert flora and fauna flourish after rainfall the response of soil microorganisms remains unclear and understudied. We provide the first systematic study of the role of soil aqueous habitat dynamics in shaping microbial community composition and diversity. Detailed monitoring ...
Growing research on the human microbiome, even beyond the gastrointestinal area, is not surprising mainly due to significant advances in study methods. Current reporting in this area is so intensive that clinicians are changing the unsuitable "bacterial flora" expression for more appropriate terms such as "microbiota" (the entire microbial community colonizing an ecologic niche), "microbiome" (...
Most periapical lesions resolve after root canal treatment of teeth with primary infections. Over the last decade there has been a renewed focus on post-treatment apical periodontitis and its etiology. This review describes the microbiota associated with persistent post-treatment infection, including microbial identification, ecology, and environmental selection. Compared with untreated teeth, ...
Regulation of intestinal inflammation by microbiota following allogeneic bone marrow transplantation
Despite a growing understanding of the link between intestinal inflammation and resident gut microbes, longitudinal studies of human flora before initial onset of intestinal inflammation have not been reported. Here, we demonstrate in murine and human recipients of allogeneic bone marrow transplantation (BMT) that intestinal inflammation secondary to graft-versus-host disease (GVHD) is associat...
Sigara içen 145 kişi ve sigara içmeyen 114 kişi olmak üzere toplam 259 kişi çalışmaya alındı. Sigara içen olguların 113’ü erkek, 32’si kadın; sigara içmeyen olguların ise 54’ü erkek, 60’ı kadındı. Olguların burun vestibül cildi %0.5 alkol-klorheksidin solusyonu ile silindi ve ilave kontaminasyonları önlemek için vestibulum nasi steril spekulum kullanılarak açıldı. Killian nazal spekulum kullanı...
AIM The objective of the present study was to identify the microbial flora within root canals of teeth with failed root-canal treatment and to determine the association of the various species with clinical features. METHODOLOGY Sixty root-filled teeth with persisting periapical lesions were selected for this study. During nonsurgical endodontic re-treatment, the root-filling material was remo...
Sutures under selective host/environmental factors can potentiate postoperative surgical site infection (SSI). The present investigation characterized microbial recovery and biofilm formation from explanted absorbable (AB) and nonabsorbable (NAB) sutures from infected and noninfected sites. AB and NAB sutures were harvested from noninfected (70.9%) and infected (29.1%) sites in 158 patients. At...
