INTRODUCTION: The non-invasive vulvar Paget's disease is an intra-epidermal carcinoma with glandular characteristics. It appears like an erythematous plaque. The main symptoms are pruritus and pain. The standard treatment is surgical excision in depth. This treatment is complicated with a severe morbidity and photodynamic therapy can be an alternative choice. However, the pain experienced during the photodynamic treatment of vulvar lesion is intense and leads to a premature interruption of the treatment...

We characterized the expression profile of angiogenesis-related genes (ARG) and matrix metalloproteinase (MMP) genes in preterm infants, with and without bronchopulmonary dysplasia (BPD). We reanalyzed a gene expression dataset for preterm infants from the Gene Expression Omnibus database using the Gene-Cloud of Biotechnology Information platform. A total of 1,652 genes were differentially (1.2-fold change) expressed: 811 were highly expressed in infants with BPD, and 841 were highly expressed in those without BPD...

Folate deficiency during pregnancy has been related to low birth weight, preterm (PT) birth and other health risks in the offspring; however, it is unknown whether prematurity is related to low folate transport through the placenta due to altered expression of specific folate transporters. We determined placental expression (mRNA and protein concentrations by RT-qPCR and WB respectively) of specific folate transporters: RFC, PCFT/HCP1 and FOLR1 in chorionic (fetal) and basal (maternal) plates of placentas of PT pregnancies (PT, 32-36 weeks, n = 51)...

Primaquine (PQ) is the only drug used to prevent relapse of malaria due to P. vivax and P. ovale, by eradicating the dormant liver form of the parasite (hypnozoites). The side effects associated with PQ limits is uses in treatment of malaria. To overcome the premature oxidative deamination and to increase the life span of drug in the biological system the novel glyco-conjugates of PQ were synthesized by coupling of primaquine with hexoses in phosphate buffer. The saccharide part of the hybrid molecules thought to be direct the drug to the liver, where hypnozoites resides...

BACKGROUND: Cystic fibrosis is a common life-shortening genetic disorder in the Caucasian population (less common in other ethnic groups) caused by the mutation of a single gene that codes for the production of the cystic fibrosis transmembrane conductance regulator protein. This protein coordinates the transport of salt (and bicarbonate) across cell surfaces and the mutation most notably affects the airways. In the lungs of people with cystic fibrosis, defective protein results in a dehydrated surface liquid and compromised mucociliary clearance...

The increasing prevalence of hypertension, a significant cause of disability and premature death throughout the world, is a major public health concern. This is especially true for the subset of patients who suffer from resistant hypertension, which is associated with a fourfold greater risk of cardiovascular events as compared to those hypertensive patients able to achieve target blood pressure. Though quite daunting in number and ill effect, hypertension remains the most common and the most important modifiable risk factor for coronary heart disease, congestive heart failure, peripheral vascular disease, stroke, and chronic kidney disease...

Arf/p53 pathway protects the cells against DNA damage induced by acute stress. This characteristic is the responsible for its tumor suppressor activity. Moreover, it regulates the chronic type of stress associated with aging. This is the basis of its anti-aging activity. Indeed, increased gene dosage of Arf/p53 displays elongated longevity and delayed aging. At a cellular level, it has been recently shown that increased dosage of Arf/p53 delays age-associated stem cell exhaustion and the subsequent decline in tissue homeostasis and regeneration...

BACKGROUND: The developmental origin of health and disease concept identifies the brain, cardiovascular, liver, and kidney systems as targets of fetal adverse programming with adult consequences. As the limits of viability in premature infants have been pushed to lower gestational ages, the long-term impact of prematurity on kidneys still remains a significant burden during hospital stay and beyond. OBJECTIVES: The purpose of this study is to summarize available evidence, mechanisms, and short- and long-term renal consequences of prematurity and identify nephroprotective strategies and areas of uncertainty...

PURPOSE: Off-label (OL) use of drugs for hospitalized children is very common. OL use occurs especially in the youngest patients, neonates. This study focused on the OL use of antimicrobials in neonates. To our knowledge, only few studies have focused on the prevalence of OL use of antimicrobials in neonates. METHODS: We investigated the OL use of antimicrobials in neonates in a tertiary children's hospital. First, we investigated what were the most consumed OL antimicrobials in defined daily doses according to hospital's registry data from neonatal intensive care unit (NICU) during 2009-2014...

Isolated left subclavian artery is one of the rarer aortic arch anomalies. It has been associated with other congenital heart diseases, typically tetralogy of Fallot, double-outlet right ventricle, and atrial and ventricular septal defects. Its significant clinical implications include a left-to-right shunt from the vertebrobasilar system, which causes pulmonary overcirculation and subclavian steal. We present an unusual case of a premature infant who was diagnosed prenatally with congenital complete atrioventricular block and tricuspid atresia and was found to have an isolated left subclavian artery postnatally...

Atrioventricular septal defects represent a class of congenital cardiac malformations that vary in presentation and management strategy depending upon the severity of the particular lesions present. We present the case of a premature neonate who had a partial atrioventricular septal defect and an accessory mitral (or left atrioventricular) valve leaflet. The latter caused severe left ventricular outflow tract obstruction and severely depressed left ventricular function. We found only one other report of this atrioventricular valve abnormality in association with atrioventricular septal defect...

Duplication of the centrosomes is a tightly regulated process. Abnormal centrosome numbers can impair cell division and cause changes in how cells migrate. Duplicated centrosomes are held together by a proteinaceous linker made up of rootletin filaments anchored to the centrioles by C-NAP1. This linker is removed in a NEK2A kinase-dependent manner as mitosis begins. To explore C-NAP1 activities in regulating centrosome activities, we used genome editing to ablate it. C-NAP1 null cells were viable and had an increased frequency of premature centriole separation, accompanied by reduced density of the centriolar satellites, with re-expression of C-NAP1 rescuing both these phenotypes...

The production of haploid gametes during meiosis is dependent on the homology-driven processes of pairing, synapsis, and recombination. On the mammalian heterogametic sex chromosomes, these key meiotic activities are confined to the pseudoautosomal region (PAR), a short region of near-perfect sequence homology between the X and Y chromosomes. Despite its established importance for meiosis, the PAR is rapidly evolving, raising the question of how proper X/Y segregation is buffered against the accumulation of homology-disrupting mutations...

With the development of treatment, the survival rate of premature infants has significantly increased, especially extremely premature infants and very low birth weight infants. This has led to an increase in incidence of bronchopulmonary dysplasia (BPD) year by year. BPD has been one of the most common respiratory system diseases in premature infants, especially the small premature infants. Arrested alveolar development is an important cause of BPD. Therefore, the mechanism of arrested alveolar development and the intervention measures for promoting alveolar development are the focuses of research on BPD...
