Lead affects multiple organ systems including testis. We investigated the effects of ferulic acid (FA) on lead-induced oxidative stress and spermatogenesis suppression in rats. Animals received lead acetate (500 mg/L in drinking water) and/or FA (50 mg/kg, i.g.) for eight weeks. Lead increased testicular malondialdehyde (MDA) and nitrite levels and decreased glutathione (GSH) content and catalase (CAT) activity. Lead decreased testis weight and testosterone level. Sperm parameters decreased in lead group...

Numerous food supplements contain phytochemical compounds as active ingredients. Though such supplements are often perceived by consumers as being risk-free, the safety of many of them is currently uncertain. The present review provides two examples for risk assessment for phytochemical ingredients which are used in certain supplements marketed for sportspeople - synephrine (extracted from fruits of Citrus aurantium) and hydroxycitric acid (HCA, isolated from fruits of Garcinia cambogia). Animal and human studies as well as case reports provide evidence for cardiovascular effects due to ingestion of high synephrine doses, especially in combination with caffeine and physical exertion...

Zika virus (ZIKV) is an emerging mosquito-borne flavivirus that has recently been found to cause fetal infection and neonatal abnormalities, including microcephaly and neurological dysfunction. ZIKV persists in the semen months after the acute viremic phase in humans. To further understand the consequences of ZIKV persistence in males, we infected Ifnar1(-/-) mice via subcutaneous injection of a pathogenic but nonlethal ZIKV strain. ZIKV replication persists within the testes even after clearance from the blood, with interstitial, testosterone-producing Leydig cells supporting virus replication...

INTRODUCTION: Redness of the nail plate-erythronychia-is a common condition involving one or multiple digits. It may affect the entire nail or present as longitudinal red bands that extend from the proximal nail fold to the distal tip of the nail plate. Rarely, red bands may traverse the nail bed horizontally. Although erythronychia is often idiopathic, it has also been associated with amyloidosis, Darier's disease, lichen planus, and various other cutaneous conditions. We describe the clinical features of a 64-year-old Caucasian man who presented with transverse and longitudinal erythronychia affecting his fingernails...

The aim of this study was to identify potential changes that could occur during histological evaluations of CLAWN miniature swine, with potential consequences for subsequent experiments. The systemic organs from male and female CLAWN miniature swine (16.3-42.3 months old) that had been used in long-term studies of coronary stent implantation were examined histologically. Commonly observed histopathological findings were testicular/epididymal atrophy, cyst-like follicles in the ovaries, hemosiderin deposition in the spleen, lipofuscin deposition in the proximal tubular epithelia and presence of eosinophilic globules in the Bowman's space and the lumen of the proximal tubules in the kidneys, and cellular infiltration in several organs, including the eyelids, respiratory organs, and digestive tract...

We report a novel syndromic disorder of sex development observed in three male siblings, presenting with the association of micropenis without hypospadias, cryptorchidism, very low level of antimüllerian hormone in the neonatal period, and no persistent müllerian duct structures, suggesting a progressive regression of testicular function. The patients described here showed a striking neurological involvement including bilateral periventricular cysts observed in the anterior part of the frontal horns prenatally and increasing in size and number over time, associated with infra and supratentorial parenchymal atrophy, dilated ventricular system, corpus callosum hypoplasia, severe intellectual disability, and epilepsy...

Mitochondrial DNA (mtDNA) mutations are thought to have a causative role in age-related pathologies. We have shown previously that mitochondrial mutator mice (PolgD257A/D257A), harboring a proofreading-deficient version of the mtDNA polymerase gamma (POLG), accumulate mtDNA mutations in multiple tissues and display several features of accelerated aging. Calorie restriction (CR) is known to delay the onset of age-related diseases and to extend the lifespan of a variety of species, including rodents. In the current study we investigated the effects of CR on the lifespan and healthspan of mitochondrial mutator mice...

Chang Il Choi, Kyung Chae Park, Tae Ho Lee, Young Kwon Hong
BACKGROUND/PURPOSE: The purpose of the study was to determine if testicular delivery during microsurgical subinguinal varicocelectomy (MSV) reduces varicocele recurrence rates in pediatric patients. Testicular delivery during MSV enables ligation of the gubernacular veins, which is thought to reduce the likelihood of varicocele recurrence. However, recent studies have suggested that testicular delivery during MSV does not offer any beneficial effect and, therefore, may be optional or unnecessary...

Sulfur mustard (SM) is a chemical warfare agent which is cytotoxic in nature, and at the molecular level, SM acts as DNA alkylating agent leading to genotoxic and reproductive effects. Mostly, the exposed areas of the body are the main targets for SM; however, it also adversely affects various tissues of the body and ultimately exhibits long-term complications including genotoxic and reproductive effects, even in the next generations. The effect of SM on reproductive system is the reason behind male infertility...

PURPOSE: Laparoscopy is being increasingly applied to pediatric inguinal hernia repair. In younger children, however, open repair remains preferred due to concerns related to anesthesia and technical challenges. We sought to assess outcomes after laparoscopic and open inguinal hernia repair in children less than or equal to 3 years. METHODS: A prospective, single-blind, parallel group randomized controlled trial was conducted at three clinical sites. Children ≤3 years of age with reducible unilateral or bilateral inguinal hernias were randomized to laparoscopic herniorrhaphy (LH) or open herniorrhaphy (OH)...
