The concentration and fate of persistent organochlorine pesticides (OCPs) in estuarine surface sediments in Erh-jen and Lan-yang rivers, Taiwan were investigated using headspace solid-phase microextraction (HSSPME) method to evaluate the possible pollution potential and guideline for OCP concentrations in Taiwan. The HSSPME method exhibits a good analytical performance with low detection limits...

BACKGROUND Using magnetic resonance imaging (MRI) to relate cardiovascular structures to surface anatomy in a population relevant to cardiac arrest victims, relate the external thoracic anterior-posterior (AP) diameter (APEXTERNAL) and blood-filled structures to recommended chest compression depths, and define an optimal compression point (OCP). METHODS MRI axial scans of referred patients we...

To test the hypothesis that progesterone, independent of estrogen, decreases the plasma osmotic threshold for arginine vasopressin (AVP) release and thirst onset, we compared AVP and thirst responses to hypertonic saline infusion (HSI) during administration of oral contraceptives (OCs) containing progesterone (OCP) with responses to infusion of OCs containing progesterone and estrogen (OCEP). E...

Una de las causas la disminución visión es catarata. El tratamiento extracción del cristalino opaco con reemplazo por un lente intraocular (LIO). La opacidad cápsula posterior (OCP) una complicación frecuente a largo plazo. Las modificaciones en el diseño LIO tanto material y forma tienen mayor importancia para prevenir OCP. Como está capsulotomía neodimio YAG láser. Objetivo: identificar OCP r...

BACKGROUND Steroid pre-treatments may be useful to program GnRH antagonist IVF/ICSI cycles. This prospective study assessed hormonal and ultrasound data collected during the free period after the discontinuation of three different pre-treatments to provide information on the optimal time interval required before starting stimulation. METHODS Women were randomized to receive oral contraceptive...

Corrosion of orthodontic miniscrews or temporary anchorage devices (TADs) has been proposed as a contributor to inflammation, which in turn is a factor in the clinical success of miniscrews. The purpose of this study was to measure the electrochemical properties of orthodontic miniscrews in artificial saliva with and without fluoride. The corrosion properties of three miniscrew products (Vector...

AIMS Ocular cicatricial pemphigoid (OCP) is a severe, potentially sight threatening systemic disease that sometimes requires systemic immunosuppression. This study assessed the clinical outcome of patients with OCP treated with sulphapyridine, a sulphonamide with an anti-inflammatory and immunosuppressive action but few side effects. METHODS A prospective, single armed, unmasked clinical tria...

Anorexia nervosa (AN) and obsessive-compulsive disorder (OCD) are highly comorbid, and appear to share a common neurophysiological dysfunction that contributes to the obsessional thoughts and compulsive behaviours seen in both disorders. Obsessive-compulsive personality (OCP) traits are also important risk factors for AN. Since excessive exercise has also been associated with greater obsessiona...

CONTEXT Researchers have recommended certain ultrasound treatment parameters for deep heating; however, we observed different parameters in the clinical setting. OBJECTIVE To compare the treatment effect of using observed clinical parameters (OCP) from 8 clinicians to the treatment effect of using the recommended parameters (RP) sited in research. DESIGN 2 x 2 repeated measures design. SE...
