High-throughput sequencing (HTS) has resulted in data for a number of herpes simplex virus (HSV) laboratory strains and clinical isolates. The knowledge of these sequences has been critical for investigating viral pathogenicity. However, the assembly of complete herpesviral genomes, including HSV, is complicated due to the existence of large repeat regions and arrays of smaller reiterated sequences that are commonly found in these genomes. In addition, the inherent genetic variation in populations of isolates for viruses and other microorganisms presents an additional challenge to many existing HTS sequence assembly pipelines...

PURPOSE: Birth acidemia is associated with short- and long-term morbidity in the child. Optimal intrapartum surveillance and timely interventions may reduce the incidence of these outcomes. Knowledge about conditions which increase the risks might be beneficial for optimal care. The aim with this study was to identify factors which increased the risk for lactacidemia in fetal scalp blood. MATERIALS AND METHODS: A secondary analysis of a cohort study performed at Karolinska University Hospital Stockholm Sweden between February 2009 and February 2011...

This study investigates gender-specific changes in the total financial return to education among persons of prime working ages (35-44 years) using U.S. Census data from 1990 and 2000, and the 2009-2011 American Community Survey. We define the total financial return to education as the family standard of living as measured by family income adjusted for family size. Our results indicate that women experienced significant progress in educational attainment and labor market outcomes over this time period. Ironically, married women's progress in education and personal earnings has led to greater improvement in the family standard of living for married men than for women themselves...

Many therapeutically-relevant protein-protein interactions (PPIs) have been reported that feature a helix and helix-binding cleft at the interface. Given this, different approaches to disrupting such PPIs have been developed. While short peptides (<15 amino acids) typically do not fold into a stable helix, researchers have reported chemical approaches to constraining helix structure. However, these approaches rely on laborious, and often expensive, chemical synthesis and purification. Our premise is that protein-based solutions that stabilize a therapeutically-relevant helix offer a number of advantages...

BACKGROUND: Genetically modified crops (GM crops) have been developed to improve the agricultural traits of modern crop cultivars. Safety assessments of GM crops are of paramount importance in research at developmental stages and before releasing transgenic plants into the marketplace. Sequencing technology is developing rapidly, with higher output and labor efficiencies, and will eventually replace existing methods for the molecular characterization of genetically modified organisms...

Obesity, a worldwide epidemic, has become a major health burden because it is usually accompanied by an increased risk for insulin resistance, diabetes, hypertension, cardiovascular diseases, and even some kinds of cancer. It also results in associated increases in healthcare expenditures and labor and economic consequences. There are also other fields of medicine and biology where obesity or being overweight play a major role, such as high-altitude illnesses (acute mountain sickness, hypoxic pulmonary hypertension, and chronic mountain sickness), where an increasing relationship among these two morbid statuses has been demonstrated...

We report a case of spontaneous pneumomediastinum with unusual clinical presentation. The most common symptoms of spontaneous mediastinum are chest pain and shortness of breath. Our patient presented with neck swelling and change in voice, an unusual presentation for spontaneous pneumothorax. A 30-year-old previously healthy man presented with complaints of neck swelling and hoarseness of voice beginning after an intense coughing spell. He had no other complaints. He denied any trauma to the chest, nausea, vomiting, recent air travel, scuba diving or recreational drug use...

There is a widespread consensus that it is important to involve patient in their own care, both for the reasons of quality and safety in healthcare and for the sake of the patients' individual rights. The appreciation of patient participation and related notions such as patient empowerment, patient centered care, patient involvement, patient as co-producers of health et cetera, indicate that the role of the patient have changed over the last decades. It has changed from being a passive recipient of treatment to becoming an active and responsible agent...

Shailesh Kumar, Hui Li
In the past few years, small peptides having anticancer properties have emerged as a potential avenue for cancer therapy. Compared to current anti-cancer chemotherapeutic drugs (or small molecules), anticancer peptides (ACPs) have numerous advantageous properties, such as high specificity, low production cost, high tumor penetration, ease of synthesis and modification. However, in wet lab setups, identification and characterization of novel ACPs is a time-consuming and labor-intensive process. Therefore, in silico designing of anticancer peptides is beneficial, prior to their synthesis and characterization...

INTRODUCTION: Pregnancies in women with spinal cord injury (SCI) are at greater risk of morbidity and mortality. Although pregnancy after SCI is well elaborated in the literature, SCI occurring during pregnancy is rarely reported. Abrupt changes in the body physiology because of SCI and the resulting disability add a risk to maternal and fetal well-being. Not only is the burden of care increased but there is also a higher risk of developing pressure ulcers, urinary tract infections, autonomic instability, intrauterine growth retardation and venous thromboembolism...

Many patients under the age of majority present to emergency departments (EDs) without parents or guardians. This may create concern in regard to evaluation of these patients without formal consent to treat. The Emergency Medical Treatment and Labor Act mandates that all patients presenting to EDs receive a medical screening examination and does not exclude these minors. Standards for who can provide consent for a patient vary from state to state and address important issues such as consent by parent surrogates, as well as adolescent emancipation, reproductive health, mental health, and substance use...

Cell reprogramming requires efficient delivery of reprogramming transcription factors into the cell nucleus. Here, we compared the robustness and workload of two protein delivery methods that avoid the risk of genomic integration. The first method is based on fusion of the protein of interest to a protein transduction domain (PTD) for delivery across the membranes of target cells. The second method relies on de novo synthesis of the protein of interest inside the target cells utilizing synthetic mRNA (syn-mRNA) as a template...

REVIEW
Adrian A Smith, Jürgen Liebig
A reproductive division of labor is a definitive characteristic of eusocial insect societies and it requires a means through which colony members can assess the presence and productivity of reproductive individuals. Cuticular hydrocarbons are the primary means of doing so across eusocial hymenopterans. However, recent experimental work presents conflicting views on how these chemical signals function, are interpreted by workers, and evolve. These recent advances include demonstrations of hydrocarbons as evolutionarily conserved 'queen pheromones' and as species-divergent 'fertility signals' used by both queens and workers...

OBJECTIVE: We present prenatal diagnosis and molecular cytogenetic characterization of a small supernumerary marker chromosome (sSMC) derived from chromosome 16. CASE REPORT: A 28-year-old woman underwent amniocentesis at 17 weeks of gestation because of abnormal maternal serum screening for Down syndrome. Amniocentesis revealed a karyotype of 47,XY,+mar[5]/46,XY[9]. Parental karyotypes were normal. Prenatal ultrasound findings were unremarkable. Array comparative genomic hybridization (aCGH) analysis of cultured amniocytes revealed a de novo 16% gene dosage increase of 16q11...

Quantifying behavior is a challenge for scientists studying neuroscience, ethology, psychology, pathology, etc. Until now, behavior was mostly considered as qualitative descriptions of postures or labor intensive counting of bouts of individual movements. Many prominent behavioral scientists conducted studies describing postures of mice and rats, depicting step by step eating, grooming, courting, and other behaviors. Automated video assessment technologies permit scientists to quantify daily behavioral patterns/routines, social interactions, and postural changes in an unbiased manner...
