Resveratrol, a polyphenolic plant antitoxin, has a wide range of pharmacological activities. In this study, we systematically evaluated the effects of resveratrol dry suspension (RDS) on immune function in piglets that were treated with different doses of RDS for 2 weeks. The results showed that the RDS has significant effects on the development, maturation, proliferation, and transformation of...

Respondent-driven sampling (RDS) is a link-tracing sampling method that is especially suitable for sampling hidden populations. RDS combines an efficient snowball-type sampling scheme with inferential procedures that yield unbiased population estimates under some assumptions about the sampling procedure and population structure. Several seed individuals are typically used to initiate RDS recrui...

background: there is an assumption that fetus with restricted growth with an inappropriate intrauterine environment lies under stress. although small-for-gestational-age (sga) infants have higher mortality, difference in the outcome of sga and appropriate-for-gestational-age (aga) infants regarding respiratory morbidity is controversial. it seems that respiratory morbidities in sga neonates is ...

It is commonly assumed that photoreceptor (PR) outer segment (OS) morphogenesis is reliant upon the presence of peripherin/rds, hereafter termed Rds. In this study, we demonstrate a differential requirement of Rds during rod and cone OS morphogenesis. In the absence of this PR-specific protein, rods do not form OSs and enter apoptosis, whereas cone PRs develop atypical OSs and are viable. Such ...

The aim was to investigate the surfactant protein B (SP-B) expression in the bronchoalveolar lavage fluid (BALF) of full-term neonates with respiratory distress syndrome (RDS). The enzyme-linked immunosorbent assay was performed to assess SP-B expression in BALF of 60 full-term neonates with RDS and 23 healthy neonates and correlation of SP-B level with RDS classification according to chest x-r...

In many countries, HIV/AIDS infections are concentrated in 3 high-risk groups: injection drug users, sex workers, and men who have sex with men. Accurate information about disease prevalence and risk behaviors in these groups is therefore critical for designing and evaluating HIV prevention programs. Respondent-driven sampling (RDS) is a relatively new method that allows researchers to collect ...

PURPOSE Rod photoreceptor outer segment (OS) morphogenesis, structural integrity, and proper signal transduction rely on critical proteins found in the different OS membrane domains (e.g., plasma, disc, and disc rim membrane). Among these key elements are retinal degeneration slow (RDS, also known as peripherin-2), rhodopsin, and the beta subunit of the cyclic nucleotide gated channel (CNGB1a),...

A novel DC-free binary convolutional coding scheme is presented. The proposed scheme achieves the DC-free and error correcting capability simultaneously. The scheme has a simple cascaded structure of the RDS(running digital sum) control encoder and the conventional convolutional encoder. A given sequence becomes DC-free if and only if the absolute RDS value of the sequence is bounded by a const...

BACKGROUND One of the key assumptions in respondent-driven sampling (RDS) analysis, called "random selection assumption," is that respondents randomly recruit their peers from their personal networks. The objective of this study was to verify this assumption in the empirical data of egocentric networks. METHODS We conducted an egocentric network study among young drug users in China, in which...
