background and objectives: a single reactive igg anti-dengue virus elisa test in the absence of igm antibodies or ns1 antigen may denote current infection or past exposure to the virus. to determine whether igg index value can be used to identify true current dengue infection we conducted a prospective observational study. materials and methods: suspected dengue patients (n =1745) were tested i...

Cigarette smoke exposure has been associated with a variety of diseases, including emphysema. The current study evaluated the interaction of cell density and cigarette smoke extract (CSE) on fibroblast contraction of collagen gels. Protein levels of transforming growth factor (TGF)-beta1, fibronectin, PGE(2), and TGF-beta1 mRNA were quantified. Although both 5 and 10% CSE inhibited contraction ...

introduction: low level laser therapy (lllt) also known as photobiomodulation, is a treatment that uses low-level lasers or light-emitting diodes (leds) to change cellular function and is a clinically well accepted tool in regenerative medicine and dentistry. considering the variety of laser, exposure, cells and study types, the exact effects of low level laser therapy seems to be unclear. the ...

In the present study, we investigated the effects of chronic exposure (14 and 28 days) to a 0.5 mT 50 Hz extremely low-frequency magnetic field (ELM) on the dendritic spine density and shape in the superficial layers of the medial entorhinal cortex (MEC). We performed Golgi staining to reveal the dendritic spines of the principal neurons in rats. The results showed that ELM exposure induced a d...

Rainbow trout, Oncorhynchus mykiss (Walbaum), were exposed continuously to infectious pancreatic necrosis virus (IPNV) at 0, 10(1), 10(3) or 10(5) plaque forming units (pfu) L(-1) of water to estimate the effects of chronic IPNV exposure on early life stages. Fish density averaged 35 fish L(-1) (low density) or 140 fish L(-1) (high density), and the tank flow rate was 250 mL(-1) min. Virus expo...

in this study, effect of two genotype imputation strategies, relatedness between reference panel and test populations and minor allele frequency on imputation error rate were examined with using a stochastic simulated population. reference panel and test populations were composed of 1,000 and 500 individuals, respectively. individuals in the reference panel were genotyped with using a high and ...
