BACKGROUND: Contemporary data regarding pregnancy outcomes in US patients with primary glomerular diseases are lacking. We aimed to report fetal and maternal outcomes among women with biopsy-proven primary glomerular disease who received obstetric care at a single large academic US center. METHODS: All women with a biopsy-confirmed primary glomerular disease diagnosis and without end-stage kidney disease who received obstetric care at the University of North Carolina (UNC) Hospitals (1996-2015) were identified using the Glomerular Disease Collaborative Network registry and the UNC Hospitals Perinatal Database...

Stimulation of β-adrenergic receptors (βAR) provides the most efficient physiological mechanism to enhance contraction and relaxation of the heart. Activation of βAR allows rapid enhancement of myocardial function in order to fuel the muscles for running and fighting in a fight-or-flight response. Likewise, βAR get activated during cardiovascular disease in an attempt to counteract the restrictions of cardiac output. However, long-term stimulation of βAR increases the likelihood of cardiac arrhythmias, adverse ventricular remodelling, decline of cardiac performance and premature death, thereby limiting the use of βAR agonists in the treatment of heart failure...

Nonsense-mediated mRNA decay, or NMD, is a quality control mechanism that identifies cytoplasmic mRNAs containing translational termination (stop) codons in specific contexts - either premature termination codons or unusually long 3΄ untranslated regions - and targets them for degradation. In recent studies, researchers in different labs have knocked out important genes involved in NMD, Upf2 and Upf3a, and one component of chromatoid bodies, Tdrd6, and examined the consequences for spermatogenesis. Disruption of Upf2 during early stages of spermatogenesis resulted in disappearance of nearly all spermatogenic cells through loss of NMD...

Background: Cardiovascular diseases are the leading cause of mortality and long-term disability worldwide. Various studies have suggested a protective effect of lactation in reducing the risk of cardiovascular diseases. Objective: This study was designed to assess the effects of pregnancy and lactation on the vulnerability of the myocardium to an ischemic insult. Methods: Eighteen female rats were randomly divided into three groups: ischemia-reperfusion (IR), in which the hearts of virgin rats underwent IR (n = 6); lactating, in which the rats nursed their pups for 3 weeks and the maternal hearts were then submitted to IR (n = 6); and non-lactating, in which the pups were separated after birth and the maternal hearts were submitted to IR (n = 6)...

OBJECTIVE: Many women experience premature menopause following cancer treatment, accompanied by psychological distress, and poor health-related quality of life. In this qualitative study, we examined how women construct their gendered subjectivities - their sense of self as a woman - in the context of premature menopause after cancer. DESIGN: We analysed data from open-ended survey items and semi-structured interviews with women who had experienced cancer. Six hundred and ninety-five women completed the online survey and 61 took part in a semi-structured interview...

BACKGROUND: The causes of death have changed with regard to the epidemiological and demographic events in society. There is no evidence of prior research into the epidemiological transition in Turkey. This transition in Turkey should be observed starting with the Ottoman Empire Period (19th to early 20th century). However, information about the Ottoman Empire is quite limited. AIMS: Our aim is to discuss the epidemiological and demographic transitions in Turkey, using demographic, educational and urbanization data in our present study...

REVIEW
Javaid Y Bhat, Gabriel Thieulin-Pardo, F Ulrich Hartl, Manajit Hayer-Hartl
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), the key enzyme of the Calvin-Benson-Bassham cycle of photosynthesis, requires conformational repair by Rubisco activase for efficient function. Rubisco mediates the fixation of atmospheric CO2 by catalyzing the carboxylation of the five-carbon sugar ribulose-1,5-bisphosphate (RuBP). It is a remarkably inefficient enzyme, and efforts to increase crop yields by bioengineering Rubisco remain unsuccessful. This is due in part to the complex cellular machinery required for Rubisco biogenesis and metabolic maintenance...

OBJECTIVE: Lung cancer is one of the leading cancers and major causes of cancer mortality worldwide. The economic burden associated with the high mortality of lung cancer is high, which accounts for nearly $180 billion on a global scale in 2008. This paper aims to understand the economic burden of lung cancer in terms of disability adjusted life years (DALY) in Australia, the Philippines, and Singapore. METHODS: The years of life lost (YLL) and years lost due to disability (YLD) were calculated using the formula developed by Murray and Lopez in 1996 as part of a comprehensive assessment of mortality and disability for diseases, injuries and risk factors in 1990 and projected to 2020...

Contrary to the known benefits from a moderate dietary reduction during adulthood on life span and health, maternal nutrient reduction during pregnancy is supposed to affect the developing brain, probably resulting in impaired brain structure and function throughout life. Decreased fetal nutrition delivery is widespread in both developing and developed countries, caused by poverty and natural disasters, but also due to maternal dieting, teenage pregnancy, pregnancy in women over 35 years of age, placental insufficiency, or multiples...

Road traffic is a major source of urban air pollution responsible for substantial premature mortality. Until recently, attention has focussed primarily on exhaust emissions of particulate matter from traffic as a causal factor. From analysis of air quality measurement data from the UK and France, we demonstrate that road traffic exhaust has a far greater impact on concentrations of nitrogen dioxide than of PM2.5. PM2.5 and carbonaceous particle concentrations have been declining appreciably since 2010/11 due to the use of diesel particle filters, but little change is seen in nitrogen dioxide over the period from 1995 to 2015...

BACKGROUND AND OBJECTIVES: Adoption of clinical respiratory scoring as a quality improvement (QI) tool in bronchiolitis has been temporally associated with decreased bronchodilator usage. We sought to determine whether documented use of a clinical respiratory score at the patient level was associated with a decrease in either the physician prescription of any dose of bronchodilator or the number of doses, if prescribed, in a multisite QI collaborative. METHODS: We performed a secondary analysis of data from a QI collaborative involving 22 hospitals...

The Neuronal ceroid lipofuscinoses (NCLs) are a group of recessive disorders of childhood with overlapping symptoms including vision loss, ataxia, cognitive regression and premature death. 14 different genes have been linked to NCLs (CLN1-CLN14), but the functions of the proteins encoded by the majority of these genes have not been fully elucidated. Mutations in the CLN5 gene are responsible for the Finnish variant late-infantile form of NCL (Finnish vLINCL). CLN5 is translated as a 407 amino acid transmembrane domain containing protein that is heavily glycosylated, and subsequently cleaved into a mature soluble protein...

BACKGROUND: Fructose is an abundant sugar in plants as it is a breakdown product of both major sucrose-cleaving enzymes. To enter metabolism, fructose is phosphorylated by a fructokinase (FRK). Known FRKs are members of a diverse family of carbohydrate/purine kinases known as the phosphofructokinase B (pfkB) family. The complete complement of active fructokinases has not been reported for any plant species. RESULTS: Protein sequence analysis of the 22 Arabidopsis thaliana pfkB members identified eight highly related predicted proteins, including one with previously demonstrated FRK activity...

A premature newborn was first transported via helicopter from place of birth to a specialty nursery 50 years ago. Since that time, the care of high-risk and premature newborns has evolved, but specialized services are not always available at the birth site. As a result, the demand for newborn transfer continues to grow. Today, neonates are transported to tertiary centers via ground ambulances, helicopters, and airplanes by highly trained personnel using sophisticated incubators and equipment.
