PURPOSE Specular images of the tear film in the central cornea were examined in patients with nasolacrimal duct obstruction to observe changes before and after dacryocystorhinostomy (DCR). METHODS We observed the specular images in 4 patients (5 eyes) by a noncontact observation device and recording system. Observed patterns were classified into five grades. The specular images and tear menis...

BACKGROUND Laser lipolysis allows the removal of small volumes of fat with concurrent sub-dermal tissue contraction. However, the physiologic consequences of this procedure are not well documented. The possible effects on serum lipids are not well established. OBJECTIVE This study was undertaken to determine what changes, if any, occurred in serum lipid profiles at different intervals (1 day,...

Highly curved bilayer lipid membranes make up the shell of many intra- and extracellular compartments, including organelles and vesicles. Using all-atom molecular dynamics simulations, we show that increasing the density of lipids in the bilayer membrane can induce the membrane to form a curved shape.

objective(s) this study was conducted to evaluate the effects of niacin on glucocorticoid-induced dyslipidemia and fatty liver in rats. materials and methods twenty four adult male rats were divided randomly into four equal groups: 1- normal saline (control), 2- dexamathasone 0.125 mg/kg/day, i.m., 3- dexamathasone + niacin 200 mg/kg/day, oral gavages, 4- niacin. after 2 weeks, serum total chol...

Cognitive abilities rise steeply from infancy to young adulthood and then are either maintained or decline to old age, depending on the specific ability. This pattern suggests corresponding continuities of mechanism and process, but it is striking that the fields of cognitive development and cognitive aging make little contact with each other's methods and theories. In this review we examine re...

The present study was conducted to test the effect of Origanum Majoranum Extract (OME) of leaves on alterations induced in a model of type 2 diabetic rats. Adult male Wistar rats were fed high fat diet for 3 weeks and injected a single dose of streptozotocin (35 mg/kg) intraperitoneally to induce type 2 diabetic rats. Diabetic rats were given aqueous extract of OME in a dose of 20 mg/kg orally ...

We studied the developmental trends of temperament and character in a longitudinal population-based sample of Finnish men and women aged 20-45 years using the Temperament and Character Inventory model of personality. Personality was assessed in 1997, 2001, and 2007 (n = 2,104, 2,095, and 2,056, respectively). Mean-level changes demonstrated qualitatively distinct developmental patterns for char...
