Rose E Ruther, Kevin A Hays, Seong Jin An, Jianlin Li, David L Wood, Jagjit Nanda
Silicon-graphite composites are under development for the next generation of high-capacity lithium-ion anodes, and vibrational spectroscopy is a powerful tool to identify the different mechanisms that contribute to performance loss. With alloy anodes, the underlying causes of cell failure are significantly different in half-cells with lithium metal counter electrodes compared to full cells with standard cathodes. However, most studies which take advantage of vibrational spectroscopy have only examined half-cells...

BACKGROUND: Intracranial aneurysms are common, occurring in about 1-2% of the population. Saccular aneurysm is a pouch-like pathological dilatation of an intracranial artery that develops when the cerebral artery wall becomes too weak to resist hemodynamic pressure and distends. OBJECTIVES: The aim of this study was to determine whether the development of intracranial aneurysms and subarachnoid hemorrhage (SAH) affects neuronal phospholipid metabolism, and what influence different invasive treatments have on brain free radical phospholipid metabolism...

Background: Ulcerative colitis (UC) patients who undergo proctocolectomy with ileal pouch-anal anastomosis (IPAA) may develop pouchitis, a poorly understood inflammatory condition. There is controversy over whether tobacco use can protect against pouchitis. We undertook this investigation to further evaluate whether smoking reduces the risk of developing pouchitis and to determine whether other previously associated clinical factors change the risk for pouchitis. Methods: We performed a retrospective analysis using a consented inflammatory bowel disease (IBD) natural history registry between the years 1995-2015 from a single tertiary care referral center...

Ileal pouch-anal anastomosis, or J pouch, surgery has become the procedure of choice for treatment of medically refractory ulcerative colitis and familial adenomatous polyposis. Overall, this operation is associated with a low rate of postoperative morbidity and good long-term function. However, when complications develop, there is a heavy reliance on imaging to facilitate an accurate diagnosis. Reported postoperative complication rates range from 5% to 35%. Complications generally can be categorized as structural, inflammatory, or neoplastic conditions...

Background: In symptomatic patients with an ileal pouch, stool studies are often sent to diagnose enteric pathogens. Aim of this study is to find the value of routine stool studies in the evaluation of symptomatic patients and the clinical implications of such pathogens in patients with ileal pouches. Methods: Consecutive ileal pouch-anal anastomosis (IPAA) patients who had stool tests out of a 2283-case registry from 2002 to 2015 were included in the study. Patients with positive stool cultures were compared with controls (symptomatic without positive stool culture) in a 1:4 ratio...

LIM-domain containing transcription factors (LIM-TFs) are conserved factors important for embryogenesis. The specificity of these factors in transcriptional regulation is conferred by the complexes they form with other proteins such as LIM-domain-binding (Ldb) proteins and LIM-domain only (LMO) proteins. Unlike LIM-TF, these proteins do not bind DNA directly. LMO are negative regulators of LIM-TF and they function by competing with LIM-TFs for binding to Ldbs. Although the LIM-TF Lmx1a is expressed in the developing mouse hindbrain, which provides many of the extrinsic signals for inner ear formation, conditional knockout embryos of both sexes show that the inner ear source of Lmx1a is the major contributor of ear patterning...

INTRODUCTION: It is well established that ileoanal pouch-related septic complications (PRSC) increase the risk of pouch failure. There are a number of publications that describe the management of early PRSC in ulcerative colitis (UC) in small series. This article aims to systematically review and summarise the relevant contemporary data on this subject and provide an algorithm for the management of early PRSC. METHOD: A systematic review was undertaken in accordance with PRISMA guidelines...

A 72-year-old male with end-stage renal disease underwent a computed tomography scan to assess renal function. An oval-shaped mass, 50 mm × 60 mm in size, was discovered incidentally in his recto-vesical pouch. Because it was suspected to be a teratoma, which could be an impediment for future renal transplantation, surgery was performed. It revealed a giant peritoneal loose body, a rare entity, that has not been reported before in patients with renal chronic insufficiency.

Decimal reduction time ( D-value) was calculated for six non-O157 Shiga toxin-producing Escherichia coli (STEC) in a laboratory medium and ground beef. For the laboratory medium, an overnight culture of each strain of STEC was divided into 10-mL sample bags and heated in a water bath for a specific time on the basis of the temperatures. Survival curves were generated by plotting the surviving bacterial population against time, and a linear-log primary model was used to estimate the D-values from survival curves...

Oesophageal atresia with trachea-oesophageal fistula is a rare foregut malformation that requires surgery soon after birth. Prenatal ultrasound diagnosis is based on the presence of polyhydramnios, a small or non-visible fetal stomach and the blind ending oesophagus, called the upper pouch (1). Neonates present with salivation, coughing, choking and attacks of cyanosis. A diagnosis of oesophageal atresia is confirmed by inserting a nasogastric tube and a thoraco-abdominal X-ray.

BACKGROUND: Mesenchymal stem cells (MSCs) are a heterogeneous subset of stromal cells currently tested for multiple therapeutic purposes. Their potential to home into tumors, to secrete trophic/vasculogenic factors, and to suppress immune response raises questions regarding their biosafety. Our aim was to evaluate whether systemically administered allogeneic MSCs modify the natural progression of precancerous lesions and whether their putative effect depends on cancer stage and/or cell dose...

Gonadotrophin-releasing hormone agonists that induce a reversible contraceptive state in several marsupials have the potential to be used to synchronize estrus. We used a model macropod, the tammar wallaby (Notamacropus eugenii), to investigate whether Lucrin Depot (AbbVie), a GnRH agonist microsphere preparation, could (1) inhibit follicular development and estrus in a cycle reactivated by removal of pouch young (RPY) and (2) facilitate a synchronous return to estrus. Our results show that females reactivated with bromocriptine and RPY in early seasonal quiescence (July 2015) were inhibited by Lucrin Depot (0...

Infection with the intravascular diecious trematode Schistosoma spp . remains a serious tropical disease and public health problem in the developing world, affecting over 258 million people worldwide. During chronic Schistosoma mansoni infection, complex immune responses to tissue-entrapped parasite eggs provoke granulomatous inflammation which leads to serious damage of the liver and intestine. The suppression of protective host immune mechanisms by helminths promotes parasite survival and benefits the host by reducing tissue damage...
