The mechanisms underlying the neurodevelopmental deficits associated with CHARGE syndrome, which include cerebellar hypoplasia, developmental delay, coordination problems, and autistic features, have not been identified. CHARGE syndrome has been associated with mutations in the gene encoding the ATP-dependent chromatin remodeler CHD7. CHD7 is expressed in neural stem and progenitor cells, but its role in neurogenesis during brain development remains unknown. Here we have shown that deletion of Chd7 from cerebellar granule cell progenitors (GCps) results in reduced GCp proliferation, cerebellar hypoplasia, developmental delay, and motor deficits in mice...

BACKGROUND: Testicular examination and the recognition of common scrotal swellings is a key clinical skill that is difficult to teach undergraduates because of its intimate nature. A novel approach for this topic was prompted by the description of handmade models in the medical literature to teach anatomical knowledge and clinical skills. METHODS: Affordable low-cost materials were purchased and assembled to form six models replicating key scrotal pathologies: epididymal cyst, epididymitis, hydrocoele, inguinoscrotal hernia, testicular tumour and varicocoele...

OBJECTIVE: Benefits of adding a second arterial graft in coronary bypass are well documented. In patients requiring mulitvessel grafting robotic totally endoscopic coronary bypass (TECAB) has allowed for routine harvesting and use of the right internal mammary artery (RIMA). We retrospectively reviewed the technical considerations and target choice in 140 cases of beating heart TECAB where a RIMA graft was used. METHODS: In 2008, we introduced beating heart TECAB with anastomotic connectors into our practice, first with single IMA and then with bilateral internal mammary artery...

BACKGROUND: The cardiovascular risk of angiogenesis inhibitors is not well-quantified. We hypothesized that, compared to direct vascular endothelial growth factor (VEGF) inhibitors (anti-VEGF antibodies or decoy receptors), small molecule agents have higher risk due to their less specific mechanism. METHODS: We searched the MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials for phase III randomised controlled trials comparing angiogenesis inhibitor-based therapy to other systemic therapy...

We have systematically changed the number of atomic layers stacked in 2D SnO nanosheet anodes and studied their sodium ion battery (SIB) performance. The results indicate that as the number of atomic SnO layers in a sheet decreases, both the capacity and cycling stability of the Na ion battery improve. The thinnest SnO nanosheet anodes (two to six SnO monolayers) exhibited the best performance. Specifically, an initial discharge and charge capacity of 1072 and 848 mAh g(-1) were observed, respectively, at 0...

Efficient water splitting requires highly active, earth-abundant, and robust catalysts. Monometallic phosphides such as Ni2P have been shown to be active toward water splitting. Our theoretical analysis has suggested that their performance can be further enhanced by substitution with extrinsic metals, though very little work has been conducted in this area. Here we present for the first time a novel PH3 plasma-assisted approach to convert NiCo hydroxides into ternary NiCoP. The obtained NiCoP nanostructure supported on Ni foam shows superior catalytic activity toward the hydrogen evolution reaction (HER) with a low overpotential of 32 mV at -10 mA cm(-2) in alkaline media...

Vitamin D, a molecular precursor of the potent steroid hormone calcitriol, has a crucial functions and roles in physiology and pathophysiology. Tellingly, Calcitriol has been shown to regulate various cellular signalling networks and cascades that have crucial role in cancer biology and diagnostics. Mounting lines of evidences from previous clinical and preclinical investigations indicate that the deficiency of vitamin D may contribute to the carcinogenesis risk. Concomitantly, recent reports suggested that significant reduction in the cancer occurrence and progression is more likely to appear after vitamin D supplementation...

Exposure to war and ongoing political violence increases mental health risks among children, especially in terms of posttraumatic stress disorder (PTSD), and depressive or somatic symptoms. However, an exclusive focus on negative functioning can lead to underestimating the coping abilities and natural potential for adjusting to trauma of war-affected children at different developmental phases. Using structural equation modelling, we tested the extent to which data gathered in a predominantly nonclinical sample of Palestinian children (N=1276) living in refugee camps supported a conceptual model in which the relationship between subjective wellbeing and the effects of trauma is mainly top-down in direction...

Inguinal hernia is the most common seen groin hernias which mostly contain bowel. The incidence of vermiform appendix in an inguinal hernia is seen in 1% of all inguinal hernia. This is known as Amyand's hernia. Appendix within a hernia can be normal or complicated by appendicitis. Most of these cases are not diagnosed preoperatively and managed during surgery. Preoperative diagnosis of these cases is so rare. Very few cases have been reported so far. In our case, we diagnosed an inflamed appendix in a 49 years old female within right inguinal hernia by using ultrasound and confirmed it by CT scan...

In view of the known vasodilatory effects of GLP-1, and exenatide, we investigated the effects of exenatide on vasoactive factors. We analyzed blood samples and mononuclear cells (MNC) from a previous study collected after a single dose and following 12 weeks of exenatide or placebo treatment on a series of 24 patients with T2DM. Following exenatide, plasma concentrations of ANP, cGMP, cAMP increased significantly at 12 weeks. Plasma cGMP and adenylate cyclase expression in MNC increased significantly following single dose...

We solve numerically the Boltzmann transport equations of the phonons and electrons to understand the thermoelectric response in heterostructures of M2CO2 (M: Ti, Zr, Hf) MXenes with transition metal dichalcogenide monolayers. Low frequency optical phonons are found to occur as a consequence of the van der Waals bonding, contribute significantly to the thermal transport, and compensate for the reduced contributions of the acoustic phonons (increased scattering cross-sections in heterostructures), such that the thermal conductivities turn out to be similar to those of the bare MXenes...

Fertility relies on a series of time dependent events, which are largely regulated by hormones. Concentration and function of these hormones can be altered by exposure of consumed and environmental toxins. It is of important to consider the dose and timing of toxin exposures in assessing the impact of them on reproductive health, however the utility of laboratory assessment in this regard is not well established. General laboratory assessment of reproduction and infertility includes hormone evaluation (hCG, prolactin, TSH, free thyroxin, FSH, LH and androgens among others) and treatment is via various assisted reproductive technologies...

A biosensor platform based on Au/MXene nanocomposite for sensitive enzymatic glucose detection is reported. The biosensor leverages the unique electrocatalytic properties and synergistic effects between Au nanoparticles and MXene sheets. An amperometric glucose biosensor is fabricated by the immobilization of glucose oxidase (GOx) enzyme on Nafion solubilized Au/ MXene nanocomposite over glassy carbon electrode (GCE). The biomediated Au nanoparticles play a significant role in facilitating the electron exchange between the electroactive center of GOx and the electrode...

PURPOSE: MRI may cause brain tissue around deep brain stimulation (DBS) electrodes to become excessively hot, causing lesions. The presence of extracranial loops in the DBS lead trajectory has been shown to affect the specific absorption rate (SAR) of the radiofrequency energy at the electrode tip, but experimental studies have reported controversial results. The goal of this study was to perform a systematic numerical study to provide a better understanding of the effects of extracranial loops in DBS leads on the local SAR during MRI at 64 and 127 MHz...

Background. Approximately, one-third of patients with epilepsy are refractory to pharmacological treatment which mandates extensive medical care and imposes significant economic burden on patients and their societies. This study intends to assess the impact of the treatment with ketogenic diet (KD) on reducing seizure-related emergency room visits and hospitalizations in children with refractory epilepsy. Methods. This is a retrospective review of children treated with the KD in one tertiary center. We compared a 12 months' period prior to KD with 12 months after the diet was started in regard to the number of emergency department (ED) visits, hospitalizations, and hospital days as well as their associated charges...
