background mesenchymal stem cells (mscs) are ideal candidates for treatment of diseases. amniotic membranes are an inexpensive source of mscs (am-msc) without any donor site morbidity in cell therapy. adipose tissue derived stem cells (ascs) are also suitable cells for cell therapy. there is discrepancy in cd271 expression among mscs from different sources. in this study, the characteristics of...

P75NTR (or CD271) is a member of the Tumor Necrosis Factor receptor (TNFR) super family of transmembrane proteins that share significant homology in their extracellular domains. Subsets of TNF receptors, including CD271, have a cytoplasmic death domain, although CD271 has unique intracellular structure and downstream signaling partners. CD271 is also differentiated from other members of the TNF...

Melanoma is one of the most dangerous and lethal skin cancers, with a considerable metastatic potential and drug resistance. It involves a malignant transformation of melanocytes. The exact course of events in which melanocytes become melanoma cells remains unclear. Nevertheless, this process is said to be dependent on the occurrence of cells with the phenotype of progenitor cells - cells chara...

Cd(2+) causes damages to several human tissues. Although the toxicological and carcinogenetic mechanisms of Cd(2+) have been previously established, some basic questions on this toxicant remain unclear. In this study, we constructed Met-cad 1.57, a new fluorescent resonance energy transfer (FRET)-based Cd(2+) indicator, which contains a portion of a Cd(2+)-binding protein (CadR) obtained from P...

Corn (Zea mays L.) stover is a primary biofuel feedstock and its expanded use could help reduce reliance on fossil fuels and net CO2 emissions. Excessive stover removal may, however, negatively impact near-surface soil properties within a short period after removal. We assessed changes in soil crust strength, bulk density (rb), and water content over a 1-yr period following a systematic removal...

High levels of genetic diversity exist among natural isolates of the bacterium Pseudomonas fluorescens, and are especially elevated around the replication terminus of the genome, where strain-specific genes are found. In an effort to understand the role of genetic variation in the evolution of Pseudomonas, we analyzed 31,106 base substitutions from 45 mutation accumulation lines of P. fluoresce...

Study Objectives: The obstructive sleep apnea hypopnea syndrome (OSAHS) is a disorder characterized by repetitive closure and reopening of the upper airway during sleep. Upper airway luminal patency is influenced by the surface tension (γ) acting within the liquid layer lining the upper airway. The aim of the present study was to examine the γ of upper airway mucosal lining liquid (UAL) in both...

tor for STDs among adolescents and young adults, especially if they fail to use condoms correctly and consistently. Most teenagers do not have multiple concurrent sexual partners; however, because many adolescent relationships are of short duration, teenagers often have multiple sequential partners. Previous research has demonstrated that adolescents are more likely than adults to report having...

strain energy is smaller on (101)/(104) planes than on the (003) plane, which might determine the more favorable crystal growth on (101)/(104) planes in our film. Only micro-Raman spectroscopy has been useful to identify LiCoO2 film patterning. In addition to the strong and sharp bands around 730 and 380 cm of the spectrum from the PTFE membrane in Figure 3b, two Raman active vibrational modes ...
