Obstructive nephropathy constitutes a major cause of pediatric renal progressive disease. The mechanisms leading to disease progression are still poorly understood. Kidney fibrotic lesions are reproduced using a model of partial unilateral ureteral obstruction (pUUO) in newborn mice. Based on data showing significant mast cell (MC) infiltration in patients, we investigated the role of MC and murine MCPT4, a MC-released chymase, in pUUO using MC- (W(sh/sh)), MCPT4-deficient (Mcpt4(-/-)), and wild-type (WT) mice...

PURPOSE: To examine the effects of autophagy deficiency induced by RPE-specific deletion of Atg5 or Atg7 in mice as a function of age. METHODS: Conditional knockout mice with a floxed allele of Atg5 or Atg7 were crossed with inducible VMD2-rtTA/Cre transgenic mice. VMD2-directed RPE-specific Cre recombinase expression was induced with doxycycline feeding in the resulting mice. Cre-mediated deletion of floxed Atg5 or Atg7 resulted in RPE-specific inactivation of the Atg5 or Atg7 gene...

Injuries and diseases that occur in the nervous system are common and have few effective treatments. Previous studies have shown that quercetin has a therapeutic effect on nervous system injuries, but its potential effects on and mechanisms of action related to behavioral recovery and axonal regrowth have not been investigated. Here, we showed that quercetin administration promotes behavioral recovery following sciatic nerve-crush injury in mice. Long-term evaluation showed that mice administered 20 mg·kg(-1)·day(-1) quercetin for 35 days had a greater sensorimotor recovery compared with all other treatment groups...

INTRODUCTION: The etiology of preeclampsia is unclear. Fetal DNA is present in higher concentrations in the plasma of pregnant women suffering from preeclampsia than in the plasma of healthy pregnant women. A previously published study has shown that human fetal DNA injected into pregnant mice induces preeclampsia-like symptoms when administered between gestation days 10-14. The aim of our experiment was to determine whether or not similar effects would be induced by administration of human and mouse fetal DNA, as well as mouse adult DNA and lipopolysaccharide during late pregnancy in the mouse...

Malformations of the rectum and urinary tract frequently coexist, and the prevalence of urogenital defects in patients with a rectal defect ranges from 20 to 54%. In most patients, anorectal malformations are diagnosed and treated surgically in early childhood. In this report, we present a case of a 52-year-old male with a history of urological operations in infancy due to a congenital urethral malformation and multiple recurrent episodes of perineal abscesses with urinary retention. Anorectal endosonography and magnetic resonance imaging revealed the presence of a large cystic lesion adjacent to the rectal wall which became smaller at the level of the puborectalis...

Severe and prolonged stress is the main environmental factor that precipitates depression, anxiety and cognitive dysfunctions. On the other hand, exposure to environmental enrichment (EE) has been shown to induce progressive plasticity in the brain and improve learning and memory in various neurological and psychiatric disorders. It is not known whether exposure to enriched environment could ameliorate chronic immobilisation stress-induced cognitive deficits and altered molecular markers. Hence, in the present study we aimed to evaluate the effect of enriched environment on chronic immobilisation stress (CIS) associated changes in spatial learning and memory, behavioural measures of anxiety, depression and molecular markers as well as structural alterations...

Myogenesis mainly involves several steps including myoblast proliferation, differentiation, apoptosis and fusion. Except for muscle specific regulators, few miRNAs were proved to coordinate this complex process. Here, we reported that miR-16 inhibited myoblast proliferation and promoted myoblast apoptosis by directly targeting Bcl2 and FOXO1. The expression level of miR-16 was significantly decreased in the hypertrophic pectoral muscle compared to the normal pectoral muscle in chicken. In vitro, elevating miR-16 significantly inhibited myoblast proliferation and promoted myoblast apoptosis, resulting in about 11...

Tauopathies include a variety of neurodegenerative diseases associated with the pathological aggregation of hyperphosphorylated tau, resulting in progressive cognitive decline and motor impairment. The underlying mechanism for motor deficits related to tauopathy is not yet fully understood. Here, we use a novel transgenic tau mouse line, Tau 58/4, with enhanced neuron-specific expression of P301S mutant tau to investigate the motor abnormalities in association with the peripheral nervous system. Using stationary beam, gait, and rotarod tests, motor deficits were found in Tau 58/4 mice already 3 months after birth, which deteriorated during aging...

Alterations in GFER gene have been associated with progressive mitochondrial myopathy, congenital cataracts, hearing loss, developmental delay, lactic acidosis and respiratory chain deficiency in 3 siblings born to consanguineous Moroccan parents by homozygosity mapping and candidate gene approach (OMIM#613076). Next generation sequencing recently confirmed this association by the finding of compound heterozygous variants in 19-year-old girl with a strikingly similar phenotype, but this ultra-rare entity remains however unknown from most of the scientific community...

Obesity and related metabolic diseases are associated with increased risk of cardiovascular disease. We have previously shown the beneficial effects of dietary magnesium (Mg) supplementation on cardiovascular disease in rats. Therefore, we aimed to examine the effect of an Mg-deficient or supplemented diet on adipose tissue cellularity changes during aging, and on blood pressure (BP), in rats. Male rats received for one (young adult) or 22 months (old), an Mg-deficient (Def) (150 mg/kg), standard (Std) (800 mg/kg) or Mg-supplemented (Sup) (3200 mg/kg) diet...

White adipose tissue expansion is associated with both hypertrophy and hyperplasia of adipocytes. Exercise training results in adipocyte hypotrophy by activating lipolysis, but it is poorly understood whether exercise regulates adipogenesis by altering adipogenic gene expression. The purpose of this study was to evaluate the effect of a single bout of swimming exercise on adipogenic gene expression in white adipose tissue (WAT). Male C57BL/6J mice were divided into two groups: a sedentary control group and a 120-minute swimming exercise group...

We present the case of two patients aged 12 years and 7 years who were referred to our hospital for factor VII deficiency inherited in an autosomal recessive pattern, who had suffered from previous multiple joint haemarthroses. They presented with fine motor symptoms and difficulty in walking. During physical examination we observed neurological symptoms (general hypotonia, muscular hypotrophy, exaggerated tendon reflexes, pes cavus, and spastic gait). Given that the symptoms were not justified by the deficiency of coagulation factor VII and on suspicion of hereditary spastic paraplegia (HSP), tests were carried out...

BACKGROUND: Mixed vascular nevus (or nevus vascularis mixtus) represents an admixture of cutaneous vascular malformations of the telangiectatic type and angiospastic spots of nevus anemicus. It can occur as an purely cutaneous trait or as a hallmark of a neurocutaneous phenotype (mixed vascular nevus syndrome) characterised by the combination of: (I) paired vascular (telangiectatic and anemic) twin nevi and brain abnormalities of the Dyke-Davidoff-Masson type (i.e., crossed cerebral/cerebellar hemiatrophy with hypoplasia of the ipsilateral cerebral vessels and homolateral hypertrophy of the skull and sinuses (hyperpneumatisation) with contralateral hemispheric hypertrophy); or (II) paired vascular twin nevi and brain malformations of the Dyke-Davidoff-Masson type in association with systemic abnormalities consisting in facial asymmetry, skeletal anomalies (i...
