INTRODUCTION: Research in animal models and preliminary clinical studies in humans support the use of pravastatin for the prevention of preeclampsia. However, its use during pregnancy is still controversial due to limited data about its effect on the human placenta and fetus. METHODS: In the present study, human placental cotyledons were perfused in the absence or presence of pravastatin in the maternal reservoir (PraM). In addition, placental explants were treated with pravastatin for 5, 24 and 72 h under normoxia and hypoxia...

The effect of lattice fluctuations and electronic excitations on the radiative rate is demonstrated in CdSe/CdS core/shell spherical quantum dots (QDs).Using a combination of time-resolved photoluminescence spectroscopy and atomistic simulations, we show that lattice fluctuations can change the radiative rate over the temperature range from 78 K to 300 K. We posit that the presence of the core/shell interface plays a significant role in dictating this behavior. We show that the other major factor that underpins the change in radiative rate with temperature is the presence of higher energy states corresponding to electron excitation into the shell...

Despite the increasing use of functional connectivity (FC) studies in fundamental and clinical research, the link between FC and behavior is still poorly understood. To test the hypothesis that artificial modulation of FC correlates with changes in behavior in a quantitative manner, we performed behavioral and resting state fMRI experiments in monkeys while perturbing, offline, the frontal eye fields (FEF) using unilateral continuous theta burst transcranial magnetic stimulation (FEF-cTBS). Stimulation of left and right FEF caused remarkably specific decreases in FC, which were symmetric for intra-hemispheric and asymmetric for inter-hemispheric FC...

SETTING: Patients who initiated treatment for multidrug-resistant tuberculosis (MDR-TB) at 15 Programmatic Management of Drug-resistant Tuberculosis (PMDT) health facilities in the Philippines between July and December 2012. OBJECTIVES: To describe patients' views of current interventions, and suggest changes likely to reduce MDR-TB loss to follow-up. METHODS: In-depth interviews were conducted between April and July 2014 with MDR-TB patients who were undergoing treatment, had finished treatment at the time of the interview (controls), or had been lost to follow-up (LTFU)...

This paper reports on a simple and environmentally friendly photochemical process capable of generating nano-layers (8-22 nm) of silver nanostructures directly onto glass surfaces. This approach opens the way to large-scale functionalized surfaces with plasmonic properties through a single light-induced processing. Thus, Ag nanostructures top-coated were obtained through photo-reduction, at room temperature, of a photosensitive formulation containing a metal precursor, free from extra toxic stabilizers or reducing agents...

Structural defects in the molybdenum disulfide (MoS2) monolayer are widely known for strongly altering its properties. Therefore, a deep understanding of these structural defects and how they affect MoS2 electronic properties is of fundamental importance. Here, we report on the incorporation of atomic hydrogen in monolayered MoS2 to tune its structural defects. We demonstrate that the electronic properties of single layer MoS2 can be tuned from the intrinsic electron (n) to hole (p) doping via controlled exposure to atomic hydrogen at room temperature...

BACKGROUND/AIMS: Similar autonomic innervation of the esophagus and left atrium with sympathovagal imbalance seems to explain the association between non-valvular atrial fibrillation (AF) and gastroesophageal reflux disease (GERD). We aimed to assess this association via parameters of heart rate variability in time (SDNN) and frequency (low-frequency (LF)/high-frequency (HF) ratio) domains by 24-hour electrocardiographic (ECG) Holter monitoring. MATERIALS AND METHODS: One hundred thirty-five patients were prospectively included by a joint team consisting of a gastroenterologist and a cardiologist on the basis of the patients' complaints...

INTRODUCTION: Pre-operative testosterone use in hypospadias surgery is known to increase penile dimensions and vascularity, which should facilitate tension-less formation of the urethral tube and tissue healing. However, androgens can have a negative effect on wound healing. There are very few randomized studies on postoperative results after androgen use, and this study attempted to understand the utility of pre-operative testosterone in distal hypospadias. OBJECTIVE: To study the effect of parenteral testosterone in children undergoing single stage urethroplasty for distal hypospadias, especially the occurrence of urethrocutaneous fistula and wound dehiscence...

OBJECTIVE: Low ejection fraction (EF < 40%) portends adverse outcomes in patients undergoing valvular heart surgery. The role of traditional median sternotomy aortic valve replacement (SAVR) compared with minimally invasive aortic valve replacement (MIAVR) in this cohort remains incompletely understood. METHODS: A multi-institutional retrospective review of 1503 patients who underwent SAVR (n = 815) and MIAVR via right anterior thoracotomy (n = 688) from 2011 to 2014 was performed...

Intra-erythrocytic growth of malaria parasite is known to induce redox stress. In addition to haem degradation which generates reactive oxygen species (ROS), the parasite is also thought to efflux redox active homocysteine. To understand the basis underlying accumulation of homocysteine, we have examined the transsulphuration (TS) pathway in the parasite, which is known to convert homocysteine to cysteine in higher eukaryotes. Our bioinformatic analysis revealed absence of key enzymes in the biosynthesis of cysteine namely cystathionine-β-synthase and cystathionine-γ-lyase in the parasite...

INTRODUCTION: We review outcomes after management of meatal balanitis xerotica obliterans (BXO). The primary outcome was recurrent meatal BXO. METHODS: A database comprising mostly hypospadias patients was queried for meatal BXO. The disease was confirmed histologically in all cases. Management included topical steroids and/or immunosuppressants, and/or surgical excision of BXO with two-stage oral mucosa graft circumferential replacement urethroplasty. RESULTS: A total of 12 patients had meatal BXO (8 boys and 4 adults)...

BACKGROUND: Circumcision has been found to be an effective strategy for lowering the transmission of HIV in Africa. The Luke Commission, a mobile hospital outreach program, has used this information to decrease the rate of HIV in Swaziland by performing voluntary male medical circumcisions throughout the country. During many of these circumcisions, genital medical conditions and penile abnormalities are simultaneously discovered and corrected. PURPOSE: The goal of our study was to evaluate the prevalence of penile abnormalities discovered and treated during voluntary male medical circumcisions performed by The Luke Commission (TLC) throughout rural Swaziland...

Involvement of the gamma-aminobutyric acid (GABA)-ergic system in schizophrenia pathogenesis through disrupted neurodevelopment has been highlighted in numerous studies. However, the function of common genetic variants of this system in determining schizophrenia risk is unknown. We therefore tested the association of 375 tagged SNPs in genes derived from the GABAergic system, such as GABAA receptor subunit genes, and GABA related genes (glutamate decarboxylase genes, GABAergic-marker gene, genes involved in GABA receptor trafficking and scaffolding) in Japanese schizophrenia case-control samples (n=2926; 1415 cases and 1511 controls)...

INTRODUCTION: Over 27,000 circumcisions were performed in England in 2012-13. The complication rate is generally perceived to be low, although published figures vary widely. Balanitis xerotica obliterans, more correctly termed Lichen Sclerosus et atrophicus (LS), is one of the commonest indications for medical circumcision. To test the hypothesis that children undergoing circumcision for LS have a higher rate of postoperative bleeding than those undergoing the procedure for other reasons, we retrospectively reviewed records for patients undergoing circumcision...

REVIEW

Immunotherapy using dendritic cell (DC)-based vaccination is an approved approach for harnessing the potential of a patient's own immune system to eliminate tumor cells in metastatic hormone-refractory cancer. Overall, although many DC vaccines have been tested in the clinic and proven to be immunogenic, and in some cases associated with clinical outcome, there remains no consensus on how to manufacture DC vaccines. In this review we will discuss what has been learned thus far about human DC biology from clinical studies, and how current approaches to apply DC vaccines in the clinic could be improved to enhance anti-tumor immunity...

Distinguishing between benign and malign adenopathies remains a challenge and could represent a source of error in a diagnosis. We report a case of right laterocervical adenopathy in a 17-year-old teenager admitted to hospital with an episode of fever associated with dysphagia, congested pharynx, and pultaceous deposits. Initially the adenopathy was considered to be secondary to a coinfection with Streptococcus B-hemolytic and Epstein-Barr virus, as suggested by the positive bacteriological and serological tests...

Wound healing is a complex cellular process involving various mechanisms making it intricate for designing a scaffold for therapeutic use. This study deals with the designing and development of coaxial electrospun Chitosan-Polycaprolactone nanofiber wound dressings for efficient simultaneous drug delivery. Ferulic acid and resveratrol were chosen for incorporation into core-shell nanofibers for their efficacy in anti-inflammatory and pro-angiogenic activities respectively. Structural and physico-chemical characterization of the scaffold confirmed the encapsulation of both the molecules...
