...ant lipid inclusions and collagen fibers are also found in the cytoplasm of these cells. These cells are found associated with the spermatogonia type B, pachytene spermatocytes and Sertoli cells. The results from this study show that there are basic similarities in the Leydig cells of the vervet compared to other mammals, humans and nonhuman primates, however, there also seem to be species differences among the mammalian group. The association of these cells w...

...stepwise digestion by XI collagenase and trypsin was used to isolate MDSCs and were purified by differential attachment technique. Cell morphology were observed using an inverted microscope, and MDSCs proliferation pattern were determined through growth curve analyses. MDSCs were identified by immunofluorescence and RT-PCR, and the immunofluorescence antibody invoved Sca-1, CD34, CD144, Desmin and CD45 which are the makers of MDSCs. Finally, MDSCs were induced...

The detection of neuronal apoptosis was measured by TUNEL assay. Using immunofluorescence, the expression of claudin-5, ZO-1 and VE-cadherin was detected. The expression of DNA methyltransferase 3b (DNMT3b) and Matrix metalloproteinase-9 (MMP-9) was ...

...roliferation and reduced collagen deposition as measured by CCK-8 assay, Sircol assay, qPCR and western blot. MSCCM also reduced the expression of the pro-fibrotic TGF-β1 and increased the expression of anti-fibrotic IFN-γ at both mRNA and protein levels. Furthermore, we found that MSCCM inhibited the activation of NF-κB signaling pathway induced by irradiation as well. Our data suggest that MSCCM could reduce irradiation-induced TGF-β1 p...

... proline residues in the collagen chain. The α subunit (P4Hα) of the P4H α2β2 tetramer contains the catalytic site, whereas the β subunit (PDI) maintains the solubility and activity of the α subunit. In this study, two plasmids were used to produce an active human P4H tetramer (rhP4H) in Pichia pastoris. The P4Hα was cloned into pPICZαA, and PDI was cloned into PHIL. Real-time PCR showed that the P4H gene wa...

A significant difference was determined between the CRF group and the control group with regard to heart rate, blood pressure, serum creatinine, BUN, LDH, cytokines and urinary electrolyte levels. Furthermore, monocyte and neutrophil apoptosis, tissue luminol, lucigenin, malondialdehyde and collagen

Thus, the present study provokes the need for quantitative histological and histo-chemical studies on the non-contractile proteins of Uromastix smooth muscle.

AGE EFFECT ON THE MECHANICAL PROPERTIES OF HIP JOINT BONE: AN EXPERIMENTAL INVESTIGATION
...s matrix binder and soft collagen as reinforcing fibers. As bone supports all the organs of a body so its
mechanical behavior is of prime importance. The mechanical properties of bone varies with age. In this paper, the
effect of age on various mechanical properties of hip joint bone was investigated experimentally. For this purpose
hip joint bone specimens of male bovine of different age groups were tested for fracture toughness, young mo...

The results indicated that the oral administration of elastin peptide greatly improved the skin elasticity, accompanying with significantly upregulated expression of hyaluronic acid and hydroxyproline. In addition, the contents of collagen in animal skin were also significantly increased, especially Type III and IV
