A 30-year-old white man reported a 10-year history of itchy, scaly fingernails that chipped and fell off easily. The nails were pitted but not painful. All of his fingernails, but none of his toenails, were affected. He also had patches of dry, scaly skin on his scalp, low...

Myofibrillar, mitochondrial, and microsomal fractions were prepared from normal and dystrophic mouse limb muscle by differential centrifugation and analyzed for phospholipids and cholesterol. Fatty acids and aldehydes of neutral lipids and of phospholipids from whole muscle and particulate fractions were also determined. Normal microsomes contained more lecithin and less total ethanolamine phos...

To examine how rod and cone function are differentially affected during retinal degeneration, and after subretinal cell grafting, we obtained light- and dark-adaptation curves by recording threshold multiunit responses from the superior colliculus of anesthetized rats. Unoperated RCS dystrophic and non-dystrophic rats were used and the effects of subretinal grafting in dystrophic rats of cells ...

The term "parrot beak nail" describes a morphologic change of the nail plate characterized by excessive forward curvature. It may be associated with systemic disease or, most commonly, occurs as an idiopathic finding complicated by delayed nail plate trimming. The characteristics of parrot beak nails in ten men are described, and the features of this acquired nail deformity are reviewed. Of the...

OBJECTIVE A new, novel product, Cynatine HNS, was evaluated for its effects as a supplement for improving various aspects of hair and nails in a randomized, double-blind, placebo-controlled clinical trial. METHODS A total of 50 females were included and randomized into two groups. The active group (n = 25) received 2 capsules containing Cynatine HNS, comprised of Cynatine brand keratin (500 m...

AIMS To investigate the cause of retinal ganglion cell (RGC) loss in dystrophic aged Royal College of Surgeons (RCS) rats. METHODS RCS-p+ (dystrophic) female rats of postnatal times (P365, P450 and P540) and age-matched RCS-p1 rdy+ (non-dystrophic) rats were used. In whole-mounted retinas, RGCs were doubly labelled with Fluorogold (FG) retrogradely transported from the superior colliculi and ...

Because standard femoral supracondylar nails have certain disadvantages, they are often replaced by traditional femoral or tibial locked nails. The purpose of this study was to make a biomechanical comparison between both types of traditional locked nails to determine which technique was more suitable for treating unstable femoral supracondylar fractures. Fourteen left Sawbones femurs (Pacific ...

Due to the existence of different races and ethnicities and their different life styles, anatomical structure of people vary from one region of the world to another. The goal of this study is to determine the anterior femoral bowing to length ratio, which can be useful for planning major medical and therapeutic projects as well as designing medical equipment (including nails, orthoses and prost...

Intracellular microelectrode recordings from chick dystrophic myotubes in cell culture reveal a capability for innervation by neurones from either dystrophic or normal embryos. Neither neuronal class differentially affects the incidence of synapse formation at neuromuscular junctions (about 75%) or at neural junctions (about 85%), the PSP frequency (about 10/sec), the maximum quantal content at...
