Neu-Laxova syndrome is a rare autosomal recessive disorder characterized by ichthyosis, intrauterine growth retardation, microcephaly, short neck, central nervous system abnormalities, hypoplastic or atelectatic lungs, limb deformities, edema, polyhydramnios, and short umbilical cord. Abnormal facial features include sloping forehead, hypertelorism, severe ectropion, proptosis, malformed ears, flat nose, and micrognathia. A necropsy study of a male infant with Neu-Laxova syndrome is described. Cleft palate and ambiguous external genitalia were present in addition to anomalies characteristic of Neu-Laxova syndrome. The clinical manifestations are compared with those of the 40 previously reported cases.

Background: Recent research has indicated that short term administration of glycine propionyl-L-carnitine (GPLC) significantly elevates levels of nitric oxide metabolites at rest and in response to reactive hyperaemia. However, no scientific evidence exists that suggests such supplementation enhances exercise performance in healthy, trained individuals. The purpose of this study was to examine the effects of GPLC on the performance of repeated high intensity stationary cycle sprints with limited recovery periods in resistance trained male subjects.

Normal fetal and newborn prostates were studied to evaluate growth patterns, histogenesis, and secretory activity. Whole cross-sectioned prostates harvested from 107 necropsies of fetuses and newborns ages 20 weeks gestation to 1 month of age were used. Development of the prostate occurred in three stages: bud stage (20-30 weeks gestation), bud-tubule stage (31-36 weeks gestation), and acinotubular stage (37-42 weeks gestation). Squamous metaplasia often appeared in the urethra, utricle, and primary lobular ducts, and occasional microcysts were noted. PAS and alcian blue-PAS positive secretion were present in 65% of the specimens by 20-30 weeks gestation and in over 87% of the specimens by 37 or more weeks gestation. Secretory activity was most prominent in the lateral regions of the peripheral zone. Prostate-specific antigen was only weakly detected throughout the prenatal period and was not related to secretory activity as evidenced by the PAS technique.
