Three-dimensional reconstruction of the rat nephron.

This study gives a three-dimensional (3D) structural analysis of rat nephrons and their connections to collecting ducts. Approximately 4,500 2.5-μm-thick serial sections from the renal surface to the papillary tip were obtained from each of 3 kidneys of Wistar rats.

The role of the RAS in programming of adult hypertension.

The aetiology of cardiovascular disease originally included two components: a genetic component and an environmental or lifestyle component. Increasing epidemiologic evidence has been accumulating during the last decades indicating the importance of a third component: the influence of the environment during foetal development. Poor living conditions resulted in a high infant mortality and influenced the incidence of cardiovascular diseases in adulthood despite better living conditions (A.

Destructive, granulating lesion in the temporal bone after elevated plasma homocysteine.

Objective: This is a presentation of a seemingly new otolaryngologic disease.

Setting: This study was conducted at a tertiary referral center.

Case Report: A 38-year-old healthy man developed left-sided sudden deafness with vertigo and temporary left facial palsy.

Brothers with Chudley-McCullough syndrome: sensorineural deafness, agenesis of the corpus callosum, and other structural brain abnormalities.

We describe two brothers with Chudley-McCullough syndrome who are 5 and 17 years old. They were born to healthy consanguineous parents of Pakistani descent. They had severe sensorineural deafness and neuroimaging showed corpus callosum agenesis and other structural brain abnormalities.

Nitric oxide synthase expression and enzymatic activity in human brain tumors.

Nitric oxide (NO) is synthesized by NO synthases (NOS), existing in 3 isoforms. NO influences a great variety of vital functions including vascular tone and neurotransmission. Under conditions of excessive formation, NO emerges as an important mediator of neurotoxicity in a variety of disorders of the central nervous system (CNS).
