Homocysteine (HCY) has recently been linked to fragility fractures. Moreover, HCY activates osteoclasts. Little is known about the effect of HCY on activity of human osteoblasts (OBs). We hypothesized that HCY decreases the activity of OBs. Osteoblasts obtained from trabecular human bone specimens of eight donors were cultured with conditioned medium. Culture medium was adjusted to 0, 100, 500,...

Objective. This study assessed T1ρ relaxation dispersion, measured by magnetic resonance imaging (MRI), as a tool to noninvasively evaluate cartilage material and biochemical properties. The specific objective was to answer two questions: (1) does cartilage initial elastic modulus (E 0 ) correlate with T1ρ dispersion effects and (2) does collagen or proteoglycan content correlate with T1ρ dispe...

A majority of oral cancers is squamous cell carcinoma and tongue carcinomas comprise 30% of all oral cancers. Phytochemicals, herbal and dietary antioxidants have been reported to prevent cancers. A nutrient mixture containing, ascorbic acid, lysine, proline and green tea extract, among other nutrients, has previously been shown to exhibit a broad spectrum chemo preventative and therapeutic ant...

Background Salvia officinalisL. has been used since ancient times but there are little data about effects of this herb on normal reproductive cells. Objective To investigate the toxicity effects of Salvia officinalis L. on granulosa cells (GCs) and maturation of oocytes. Materials and Methods GCs and oocytes were extracted from superovulated ovaries of immature mice. The cells were treated ...

The aim of this study was to assess the teratogenicity of the herbicide glyphosate-Roundup (as commercialized in Brazil) to Wistar rats. Dams were treated orally with water or 500, 750 or 1000 mg/kg glyphosate from day 6 to 15 of pregnancy. Cesarean sections were performed on day 21 of pregnancy, and number of corpora lutea, implantation sites, living and dead fetuses, and resorptions were reco...

UNLABELLED Studies have reported compatibility between hearing and electrophysiological thresholds in the auditory brainstem response (ABR) with tone burst stimuli. AIMS to verify waves I, III, V and their latency times for tone bursts at 500, 1000, 2000 and 4000 Hz and at 80 dB HL, and to compare tone burst electrophysiological thresholds with those obtained from audiological and psychoacous...

Materials and methods: Th is is a prospective, open-label, single-centre study. Th e study involved 86 consecutive patients with nonulcer dyspepsia. All patients were randomly assigned into 2 study groups at a 2:1 ratio using random sampling numbers. Th e fi rst group of patients were administered a sequential treatment: pantoprazole 2 × 40 mg and amoxicillin 2 × 1000 mg for the fi rst 7 days a...
