Estrogen and estrogen receptors (ERs) are known to play important roles in the pathophysiology of osteoarthritis (OA). To investigate ER-alpha gene polymorphisms for its associations with primary knee OA, we conducted a case-control association study in patients with primary knee OA (n = 151) and healthy individuals (n = 397) in the Korean population. Haplotyping analysis was used to determine ...

Converter-connected resources, such as electric vehicles and stationary batteries, are being recognized by grid operators contributors to frequency stability. Their fast-response potential makes them ideal candidates provide fast control. In this paper we discuss present evidence on what kind of dynamics a power system experiences when using Initially, method assess balance deriving so called r...

Transport of Bose-Einstein condensates in magnetic microtraps, controllable by external parameters such as wire currents or radio-frequency fields, is studied within the framework of optimal control theory (OCT). We derive from the Gross–Pitaevskii equation the optimality system for the OCT fields that allow to efficiently channel the condensate between given initial and desired states. For a v...

introduction: acoustic transient cavitation is the primary mechanism of sonochemical reaction and has potential use for tumor treatment. in this study, the in vivo anti-tumor effect of simultaneous dual-frequency ultrasound at low-level intensity (isata < 6 w/cm2) was investigated in a spontaneous murine model of breast adenocarcinoma in balb/c mice. materials and methods: forty tumor bearing m...

objectives: implant primary stability is one of the important factors in achieving implant success. the osteotome technique may improve primary stability in patients with poor bone quality. the aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. materials and methods: in this controlled randomi...

In India, mutations in Cytochrome P450 (CYP1B1) are a predominant cause of not only primary congenital glaucoma (PCG) but also involved in primary open angle glaucoma (POAG) and juvenile onset glaucoma (JOAG). After ethical clearance, 100 POAG patients, 30 primary angle closure glaucoma (PACG) patients and 130 ethnically matched controls were recruited in this study. Genomic DNA was is...
