To ascertain whether used and re-refined lubricant oil absorbed through the skin can produce a genotoxic effect or cytotoxicity in mouse bone marrow cells, we examined the induction of micronucleated erythrocytes of peripheral blood after cutaneous application. Both re-refined and used lubricant oils showed a weak but signific.. Read More»

Transforming growth factor-β1 (TGF-β1) is a member of the TGF-β superfamily, and plays an important role in promoting various stages of intramembranous and endochondral bone formation. It is one of the major growth factors that influence new bone formation in the distraction gap during distraction osteogenesis (.. Read More»

Porcine ear size is an important characteristic for distinguishing among pig breeds. In a previous genome-wide association study of porcine ear size, LEM domain-containing 3 (LEMD3), methionine sulfoxide reductase B3 (MSRB3), high mobility group AT-hook 2 (HMGA2), and Wnt inhibitory factor 1 (WIF1) were implicated as important..

Sacral nerve stimulation (SNS) is an alternative surgical approach to alleviate fecal incontinence and constipation. This study aimed to explore the effects and underlying mechanisms of SNS with acupuncture on gut transit time and colon c-kit protein expression in rats with slow transit constipation (STC). Fifty Sprague-Dawley rats were randomly divided i.. Read More»

Inflammation plays an important role in cerebral ischemia reperfusion, which can cause severe damage to the brain and may lead to cerebral hemorrhage transformation. p38-mitogen-activated protein kinase (p38mapk) has been implicated in the etiology of a number of diseases because it is a cause of inflammation, but comparatively little research has been ca..

A comparative study of holocentric chromosomes in the triatomine species Panstrongylus megistus, Rhodnius pallescens and Triatoma infestans was carried out in order to characterize heterochromatin, rDNA active sites and nucleolar proteins. Cytological preparations of seminiferous tubules were stained by silver impregnation, C .. Read More»

Toxoplasma gondii is an obligate intracellular parasite that is able to infect almost all mammalian species, and may lead to toxoplasmosis of the host. In the present study, we examined sequence variation in rhoptry protein 38 (ROP38) genes among T. gondii isolates collected from different hosts and geographi.. Read More»

Molecular identification is very useful in cases where morphology-based species identification is not possible. Examples for its application in cetaceans include the identification of carcasses of stranded animals in advanced state of decomposition and body parts that are illegally traded. One DNA region that is often used for.. Read More»

Sphyraena (barracudas) represents the only genus of the Sphyraenidae family and includes 27 species distributed into the tropical and subtropical oceanic regions. These pelagic predators can reach large sizes and, thus, attracting significant interest from commercial and sport fishing. Evolutionary data for this fish group, as.. Read More»

The corticotrophin-releasing hormone (CRH) and proopiomelanocortin (POMC) genes are considered to play an important role in the growth and development of mammals. In this study, the bovine CRH and POMC genes were characterized to detect genetic variation at these loci in relation to economic traits in Korean cattle (Hanwoo). Nine single nucleotide polymor..
