Candida glabrata is reported as the second most prevalent human opportunistic fungal pathogen in North America and is threatening patients all over the world. Its incidence is rising, while it has developed resistance to the most widely used antifungal drugs, necessitating new approaches based on better insight into the biology of the organism. Despite its close phylogenetic relationship with Saccharomyces cerevisiae, generating precise genomic alterations in this species is problematic. Previously we have shown that deletion of LIG4, which encodes an enzyme involved in Non-Homologous End Joining (NHEJ), strongly enhances the probability of obtaining correctly modified transformants...

INTRODUCTION: Infiltration and extravasation account for 23-78 % of the complications stemming from peripheral venous perfusions in neonatal intensive care units. Their consequences, sometimes dramatic, can be pain, infections, or even loss of skin, which can lead to nerve and/or muscle damage, particularly severe for preterm neonates. Today there are no recommendations on the care of these lesions, which can lead to an erroneous choice or to a delay in the possible treatments. OBJECTIVE: This review of the literature aims to explore and propose elements of therapeutic care collected in the scientific literature...

The placenta plays a major role in embryo-fetal defects and intrauterine growth retardation after maternal alcohol consumption. Our aims were to determine the oxidative status and cellular and molecular oxidative stress effects on uterine myometrium and trophoblast-decidual tissue following perigestational alcohol intake at early organogenesis. CF-1 female mice were administered with 10% alcohol in drinking water for 17 days prior to and up to day 10 of gestation. Control females received ethanol-free water...

It is increasingly recognized that the abnormal physiologic consequences of pulmonary hypertension (PH) may contribute to poor cardiopulmonary health in premature babies. Conflicting literature has led to clinical uncertainty, pathological misinterpretation and variability in treatment approaches among practitioners. There are several disorders with overlapping and interrelated presentations and other disorders with a similar clinical phenotype but diverse pathophysiological contributors. In this review, we provide a diagnostic approach for acute HRF in the preterm neonate, outline the pathophysiological conditions that may present as acute PH and discuss the implications of high pulmonary vascular resistance (PVR) on the cardiovascular system...

Whale tracking tags often penetrate semi-rigid blubber, with intramuscular sharp tips and toggling barbs under the subdermal sheath to reduce premature shedding. Tag sites can show persistent regional swellings or depressions. Fibroelastic blubber grips a tag, so if muscle shears relative to blubber during locomotion, the tag tip could cavitate the muscle within overall shearing distance. We modelled shearing of blubber relative to muscle, within the dorsal-ventral peduncular movement range of four common dolphin (Delphinus delphis) cadavers (mean length 186 cm)...

BACKGROUND: The purpose of this study was to show whether and how levels, trends and patterns obtained from estimates of premature deaths from adverse effects (AEs) of medical treatment depended on the deprivation level in England over the 24-year period, 1990-2013. We provide a report to inform decision-making strategies to reduce the burden of disease arising from AEs of medical treatment in the most deprived areas of the country. METHODS: Comparative analysis was driven by a single cause-of-injury category-AEs of medical treatment-from the Global Burden of Disease 2013 study...

Bronchopulmonary dysplasia (BPD) is characterized by impaired alveolar secondary septation and vascular growth. Exposure to high concentrations of oxygen (hyperoxia) contributes to the development of BPD. Male sex is considered an independent risk factor for the development of BPD. The reasons underlying sexually dimorphic outcomes in premature neonates are not known. We hypothesized that sex-specific modulation of biological processes in the lung under hyperoxic conditions, contributes to sex-based differences...

In climates that experience short growing seasons due to drought, heat or end-of-season frost, early flowering is a highly desirable trait for chickpeas. In this study, we mapped, sequenced and characterized Efl1, an ortholog of Arabidopsis ELF3 that confers early flowering in chickpea. In a RIL population derived from a cross between CDC Frontier and ICCV 96029, this gene was mapped to the site of a QTL on Ca5 that explained 59% of flowering time variation under SD. Sequencing of ELF3 in ICCV 96029 revealed an 11-bp deletion in the first exon that was predicted to result in a premature stop codon...

Ultraviolet (UV) radiation has adverse effects on extracellular matrix (ECM) proteins, leading to formation of wrinkles a hallmark of premature skin aging. The adverse effects of UV radiation are associated with induction of matrix metalloproteinases (MMPs) expression and degradation of collagen and elastin. The present study investigated anti-wrinkle effects of chlorogenic acid (CGA), pyrocatechol (PC) and 3,4,5-tricaffeoyl quinic acid (TCQ), isolated from beans of Coffea arabica, against UV-B stimulated mouse fibroblast cells (CCRF) by measuring expression levels of MMP-1, 3, 9, and type-I procollagen...

REVIEW
Hany Aly, Mohamed A Mohamed, Jen-Tien Wung
The discovery of surfactant was one of the most significant research events to occur in the history of neonatology. Certainly, surfactant saved lives for premature infants who were otherwise considered non-viable. However, the prevention of chronic lung disease did not progress and it became clear that a significant portion of the help surfactant provides to the premature lung is counteracted by mechanical ventilation. A dilemma exists over the priorities in premature management to intubate and administer surfactant or not to intubate and support these infants non-invasively with the use of continuous positive airway pressure...
