The essential oils, isolated by hydrodistillation from the leaves, seeds and rhizomes of Heracleum sprengelianum (Wight and Arnott), collected from the Western Ghats of Peninsula India, were analyzed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GC–MS). The antioxidant property of these oils was tested, with and without peroxidation inducer, through the egg yol...

OBJECTIVE To compare the efficacy of two doses (250 microg vs. 500 microg) of r-hCG for oocyte maturation in obese women with a body mass index (BMI) > or = 30 and undergoing assisted reproduction techniques. MATERIALS AND METHODS A Prospective, randomized, clinical study of seventy two patients undergoing IVF/ intracytoplasmic sperm injection cycles with BMI > or = 30 kg/m2. Patients with hi...

BACKGROUND The rate of non-compliance with vitamin D supplementation is as high as 45%. This is why randomised controlled trials are needed to analyse the response to low doses of vitamin D3. OBJECTIVE (1) To compare supplementation with 250 versus 500 units of vitamin D3 and (2) to analyse sun exposure time/ultraviolet B (UVB) exposure during the first 6 weeks of life. DESIGN 40 breastfed ...

the residual activity and air-borne efficacy of etofenprox (trebon 20% wp) were studied on different surfaces in hut scale trial, in kazeroun south of iran, in 1992. the bio-assay contact mortality tests with trebon against anopheles stephensi showed similar responses on pluster, cement and mud surfaces (except wooden surfaces), i.e. at 250, 400 and 500 mg/m2, trebon had residual activity for a...

A total of 2259 urine samples were assayed for lysergic acid diethylamide (LSD) using radioimmunoassay (RIA, Coat-a-Count, Diagnostics Products) and a premarket cloned enzyme donor immunoassay (CEDIA, Boehringer Mannheim). Urine samples were obtained from patients admitted to the emergency room, patients in drug rehabilitation programs, and adults and juveniles in criminal probation programs. A...

Onpi-to, an herbal medicine composed of five crude drugs (Rhei Rhizoma, Glycyrrhizae Radix, Ginseng Radix, Zingiberis Rhizoma and Aconiti Tuber), was administered orally to rats. Onpi-to includes 1.240% of total potential rhein derived from sennoside A, sennoside B, rhein 8-O-glucopyranoside and rhein. Plasma, urinary and biliary levels of rhein were determined by an HPLC-UV method. The plasma ...

Analysis of both pulse timing and pulse shape variations of the isolated pulsar PSR B1828-11 shows highly correlated and strong Fourier power at periods ≃ 1000, 500, 250, and 167 d (Stairs et al. 2000). The only description based on a free precession of star’s rigid crust coupled to the magnetic dipole torque, explains the 500component, as the fundamental Fourier frequency, with its harmonic 25...

BACKGROUND AND AIM Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in children. We tested whether dietary supplementation with docosahexaenoic acid (DHA) can decrease liver fat content in children with NAFLD. METHODS AND RESULTS We performed a randomized controlled trial of DHA supplementation (250 mg/day and 500 mg/day) vs. placebo in 60 children with NAFLD (20 chi...
