background: this study was designed to develop a new co-culture system, assess the effect of luteinizing hormone (lh) using sequential media to promote development and increase the quality of 2-cell murine embryos through the 8-16 cell stage to morula and blastocyst stages. materials and methods: monolayers for co-culture were prepared from ovine oviduct epithelial cells (ooec) in dmem/f12 medi...

BACKGROUND/AIM Inflammation plays a key role in the physiopathology of arteriosclerosis. C-reactive protein (CRP) and common carotid artery intima-media thickness are independent predictors of cardiovascular events and diabetes mellitus in apparently healthy men, but relationship between them is not fully elucidated. The aim of the study was to assess the cross-sectional relationship between CR...

OBJECTIVES/HYPOTHESIS Despite the advancement of concurrent chemoradiotherapy, inner ear symptoms such as hearing loss, tinnitus, or vertigo/dizziness are still experienced in irradiated nasopharyngeal carcinoma (NPC) survivors. This study utilized an inner ear test battery to assess the causes and sequence of inner ear deficits in irradiated NPC survivors with a mean interval of 10 years after...

OBJECTIVE Vascular adhesion protein-1 is an endothelial enzyme that regulates leukocyte traffic and contributes to vascular damage in animal models. The relations of soluble vascular adhesion protein-1 (sVAP-1) with cardiovascular risk factors and markers of subclinical atherosclerosis at a population level have not been studied. METHODS AND RESULTS We developed a new high-throughput method a...

Traditional and modern mass media – such as television, newspapers, magazines, and Internet sites – typically derive the bulk of their revenues from advertisements rather than subscriptions. We present a simple model that explains this phenomenon.  2000 Elsevier Science S.A. All rights reserved.

background: a hemangioma is a rather common benign soft tissue tumor that rarely originates from both the pectoralis muscle and the breast. vascular tumors of the breast, such as benign hemangiomas, are rarely seen in men. case presentation: a 40-year-old man presented with a non-tender palpable right breast mass since 6 months ago. on physical examination, a hard lump was detected in the centr...

Modern snakes probably originated as habitat specialists, but it controversial unclear whether they were ancestrally terrestrial burrowers or marine swimmers. We used x-ray virtual models of the inner ear to predict the habit of Dinilysia patagonica, a stem snake closely related to the origin of modern snakes. Previous work has shown that modern snakes perceive substrate vibrations via their in...
