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 ...

Purpose: The aim of this research forum article was to describe a feasible web-based solution for improving the quality of life of persons with hearing problems, such as hearing loss or tinnitus. The online platform was developed at the Department of Behavioural Sciences and Learning at Linköping University, Sweden, and has been running for a number of years and used in numerous studies and tre...

The number of people suffering from metabolic diseases is dramatically increasing worldwide. This stresses the need for new therapeutic strategies to combat this growing epidemic of metabolic diseases. A reduced mitochondrial function is one of the characteristics of metabolic diseases and therefore a target for intervention. Here we review the evidence that mitochondrial function may act as a ...

c) (The advantage of the statistical formulation is that makes the assumptions explicit. We will now challenge some of these.) Assume that instead of a fixed variance σ we now have a variance that depends on the sample point, i.e. zi = f(xi, θ) + ǫi, (3) where ǫi ∼ N (0, σ i ). This means that our sample is independent but no longer identically distributed. It also means that we have different ...

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...

Exposure of Atlantic salmon smolts to estrogenic compounds is shown to compromise several aspects of smolt development. We sought to determine the underlying endocrine mechanisms of estrogen impacts on the growth hormone (GH)/insulin-like growth factor I (IGF-I) axis. Smolts in freshwater (FW) were either injected 3 times over 10 days with 2 μgg(-1) 17β-estradiol (E2) or 150μgg(-1) 4-nonylpheno...

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...
