Skeletal muscle is mainly composed of myofibers and intramuscular connective tissue. Bundles composed of many myofibers, with each myofiber sheathed in connective tissue called the endomysium, are packed in the perimysium, which occupies the vast bulk of the intramuscular connective tissue. The perimysium is a major determination factor for muscle texture. Some studies have reported that collag...

We investigated the expression and function of laminin and type IV collagen (COL-4) in the human endometrial epithelium throughout the menstrual cycle. Their expression was demonstrated by immunohistochemistry, while cytological analysis of the human endometrial epithelial cell line HHUA cultured on laminin- or COL-4-coated plates provided information on their roles in cell proliferation, struc...

Damage to cartilage causes a loss of type II collagen (Col-II) and glycosaminoglycans (GAG). To restore the original cartilage architecture, cell factors that stimulate Col-II and GAG production are needed. Insulin-like growth factor I (IGF-I) and transcription factor SOX9are essential for the synthesis of cartilage matrix, chondrocyte proliferation, and phenotype maintenance. We evaluated the ...

Bovine colostrum (COL) has been advocated as a nutritional countermeasure to exercise-induced immune dysfunction. The aims of this study were to identify the effects of 4 weeks of COL supplementation on neutrophil responses and mucosal immunity following prolonged exercise. In a randomized double-blind, parallel group design, participants [age 28 ± 8 years; body mass 79 ± 7 kg; height 182 ± 6 c...

T cell-mediated autoimmunity to collagen V (col-V), a sequestered yet immunogenic self-protein, can induce chronic lung allograft rejection in rodent models. In this study we characterized the role of CD4+ CD25+ regulatory T cells (Tregs) in regulating col-V autoimmunity in human lung transplant (LT) recipients. LT recipients revealed a high frequency of col-V-reactive, IL-10-producing CD4+ T c...

The aim of this research is to explore the effect of miR-200b-3p targeting DNMT3A on the proliferation and apoptosis of osteoarthritis (OA) cartilage cells. Quantitative RT-PCR was performed to analyse the expression of miR-200b-3p, DNMT3A, MMP1, MMP3, MMP9, MMP13 and COL II in normal and OA cartilage tissues. The dual-luciferase reporter assay and Western blot assay were conducted to confirm t...

Whereas the segmental nature of the insect head is well established, relatively little is known about the genetic and molecular mechanisms governing this process. In this paper, we report the phenotypic analysis of mutations in collier (col), which encodes the Drosophila member of the COE family of HLH transcription factors and is activated at the blastoderm stage in a region overlapping a para...

The College of Letters (COL) is a three-year interdisciplinary major for the study of European literature, history, and philosophy, from antiquity to the present. During these three years, students participate as a cohort in a series of five colloquia in which they read and discuss (in English) major literary, philosophical, and historical texts and concepts drawn from the three disciplinary fi...

This paper demonstrates the demand of elearning that needs to cope with and possible technology introduction through Bangladesh Open University as a lone government agency of distance education in Bangladesh for its learners who are doing Commonwealth Executive MBA (CEMBA)/Commonwealth Executive MPA (CEMPA) offered in cooperation with Commonwealth of Learning (COL) and MBA program of its own. W...

PURPOSE The purpose of this research was to assess the feasibility of administering Col-3, an oral chemically modified tetracycline derivative with potent inhibitory effects on matrix metalloproteinase activity and production, and recommend a dose on an uninterrupted once-daily schedule. The study also sought to characterize the pharmacokinetic behavior of Col-3 and seek evidence of anticancer ...
