OBJECTIVES: To evaluate the differences in arterial flow after flow diverter placement using quantitative flow measurements based on digital subtraction angiography (DSA). METHODS: Between November 2013 and November 2015, all patients who had flow diverters placed for distal internal carotid artery (ICA) aneurysms were reviewed. Patients in whom the stent was placed across the ostia of the ophthalmic artery (OphA) and anterior choroidal artery (AChA) were enrolled...

Adult neurogenesis within the dentate gyrus (DG) of the hippocampus can be increased by voluntary exercise but is suppressed under stress, such as with corticosterone (CORT). However, the effects of exercise and CORT on the cell proliferation of the other traditional neurogenic site, the subventricular zone (SVZ), have been reported with controversial results. In addition, the cotreatment effects of voluntary exercise and CORT have not been investigated. This study aims to determine whether CORT can suppress cell proliferation in the SVZ and whether this can be reversed by voluntary exercise...

Umbilical cord blood-derived mononuclear cell (UCB-MNC) transplants improve recovery in animal spinal cord injury (SCI) models. We transplanted UCB-MNCs into 28 patients with chronic complete SCI in Hong Kong (HK) and Kunming (KM). Stemcyte Inc. donated UCB-MNCs isolated from human leukocyte antigen (HLA 4:6)-matched UCB units. In HK, four patients received four 4-l injections (1.6 million cells) into dorsal entry zones above and below the injury site, and another four received 8-l injections (3.2 million cells)...

Obesity is associated with structural and functional changes in the perivascular adipose tissue (PVAT), favoring the release of reactive oxygen species (ROS), vasoconstrictor and proinflammatory factors. Tumor necrosis factor alpha (TNF-α) induces vascular dysfunction and is produced by the PVAT. We tested the hypothesis that obesity-associated PVAT dysfunction is mediated by augmented mitochondrial ROS (mROS) generation due to increased TNF-α production in this tissue. Aortae from high fat diet (HFD)-fed obese mice displayed increased contractions to phenylephrine (PE) and loss of PVAT anticontractile effect...

Over activity of cannabinoid receptor type 1 (CB1R) plays a key role in increasing the incidence of obesity-induced nonalcoholic fatty liver disease. Tissue proteome analysis has been applied to investigate the bioinformatics regarding the mode of action and therapeutic mechanism. The aim of this study was to explore the potential pathways altered with CB1R in obesity-induced fatty liver. Male C57BL/6 mice were fed either a standard chow diet (STD) or a high-fat diet (HFD) with or without 1-week treatment of CB1R inverse agonist AM251 at 5 mg/kg...

The pacific islands of Micronesia have experienced several outbreaks of mosquito-borne diseases over the past decade. In outbreaks on small islands, the susceptible population is usually well defined, and there is no co-circulation of pathogens. Because of this, analysing such outbreaks can be useful for understanding the transmission dynamics of the pathogens involved, and particularly so for yet understudied pathogens such as Zika virus. Here, we compared three outbreaks of dengue and Zika virus in two different island settings in Micronesia, the Yap Main Islands and Fais, using a mathematical model of transmission dynamics and making full use of commonalities in disease and setting between the outbreaks...

Tumor therapy needs new approaches in order to improve efficacy and reduce toxicity of the current treatments. The acidic microenvironment and the expression of high levels of endogenous non-telomerase reverse transcriptase (RT) are common features of malignant tumor cells. The anti-acidic proton pump inhibitor Lansoprazole (LAN) and the non-nucleoside RT inhibitor Efavirenz (EFV) have shown independent antitumor efficacy. LAN has shown to counteract drug tumor resistance. We tested the hypothesis that combination of LAN and EFV may improve the overall antitumor effects...

PURPOSE: Pterygium is a common ocular surface disorder. Conjunctival autografting (CAG) following pterygium resection is the gold standard treatment. CAGs without Tenon's tissue provide better results but are more technically difficult to achieve. In this study, we evaluated the feasibility and reproducibility of femtosecond laser (FSL)-assisted CAG preparation. METHODS: Fifteen porcine globes were fixed in a suction holder and CAGs of different diameters were created by 1) an experienced consultant and 2) a less experienced fellow using the Ziemer LDV Z8...

Chronic expanding hematoma is a rare pathology, which has not been previously described as a complication of gunshot injury with retained bullet fragments. Because of the similar characteristics of chronic expanding hematoma to malignancy, it can present a diagnostic challenge for clinicians. Imaging and biopsy evaluation is needed to reach a conclusive diagnosis and implement appropriate treatment. In this case report, we will discuss the development, diagnosis, and management of a chronic superficial cervicothoracic mass in a patient who presented 30 years post-gunshot injury with retained bullet fragments...

This paper describes the method development for sulfadimethoxine (SDM) and ormetoprim (OMP) quantitation in fish feed and fish fillet employing LC-MS/MS. In order to assess the reliability of the analytical method, valuation was undertaken as recommended by guidelines proposed by the Brazilian Ministry of Agriculture. The calibration curve for quantification of both drugs in feed showed adequate linearity (r > 0.99), precision (CV < 12%) and trueness ranging from 97 to 100%. The method for the determination of SDM and OMP residues in fish fillet involving a simple sample preparation procedure which had adequate linearity (r > 0...

Previously, we reported that GPR30 activation by the receptor-specific, non-estrogenic ligand G-1 inhibited in vitro and in vivo growth of prostate cancer (PCa) cells via sustained Erk1/2 activation. Mechanism underlying the sustained Erk1/2 activation for PCa cell growth inhibition remains unclear. Here we report that G-1, through GPR30, activated Gαi1 proteins to sustain Erk1/2 activation but failed to activate adenylyl cyclase (AC) for cAMP production in PCa cells. The chemical-induced activation of AC-cAMP-PKA signaling attenuated Erk1/2 activity and blocked the cell growth inhibitory effects of G-1...

Myofibroblasts play a central role in renal fibrosis although the origin of these cells remains controversial. We recently reported that bone marrow-derived macrophages can give rise to myofibroblasts through macrophage to myofibroblast transition (MMT). However, several important issues remain to be addressed, including whether MMT occurs in human kidney disease and verification of the MMT process through lineage tracing. Biopsies from a cohort of 58 patients with various forms of kidney disease were examined for MMT cells that co-express macrophage (CD68) and myofibroblast (α-smooth muscle actin, α-SMA) markers...

BACKGROUND: Femoroacetabular impingement (FAI) is common with an estimated prevalence of 10-15% among young active individuals. The natural history of the disorder is progression to early osteoarthritis. Hip arthroscopy is recommended if conservative treatments fail; however, outcomes are unclear, particularly in highly active populations. AIM: To evaluate the functional and vocational outcome of hip arthroscopy, as part of an evidence-based rehabilitation hip pain pathway, for the treatment of FAI in an active military population...

Post-transplant lymphoproliferative disorder (PTLD) is associated with a variety of clinical presentations, but rarely involves the skin. We herein report a case of PTLD presenting with skin ulceration in a renal transplant recipient. A biopsy of the ulcer confirmed the diagnosis of diffuse large B-cell lymphoma. The patient was initially treated with immunosuppression reduction, but the skin ulcer persisted. He was then treated with two courses of chemotherapy, but his condition was complicated with cryptococcal infection...
