Artemisia campestris (Asteraceae) is widely used in traditional medicine in Southern Tunisia as a decoction for its antivenom, anti-inflammatory, antirheumatic, and antimicrobial activities. A. campestris essential oil (ACEO) was obtained by hydrodistillation from the aerial parts, since it has beneficial and therapeutic effects. Deltamethrin is a synthetic pyrethroid with broad spectrum activities against acaricides and insects and widely used for veterinary and agricultural purposes. Exposure to deltamethrin leads to nephrotoxic and neurotoxic side effects for human and many species including birds and fish...

PURPOSE: Bevacizumab is an active anti-angiogenic agent in the treatment of recurrent glioblastoma. Temozolomide can prolong survival in patients with newly diagnosed glioblastoma. At recurrence, alternate dosing of temozolomide has shown to further deplete methyl-guanine-methyltransferase (MGMT) conferring added activity for patients who have progressed on the standard dosing regimen. In this study, bevacizumab plus biweekly temozolomide was evaluated for efficacy in adult patients with recurrent glioblastoma...

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been considered as a valuable approach in treatment of numerous malignant and none malignant hematologic disorders. However, relapse and poor graft function (PGF) after allo-SCT remain to be controversial issues which may affect the transplantation outcome. Relevant articles were searched in MEDLINE database (2000-2016) using keywords and phrases: donor lymphocyte infusions, allogeneic stem cells transplantation, relapsed hematologic malignancies, booster schedules, cell dose, laboratory monitoring protocols and technical aspects of apheresis...

Chalcones have been shown to exhibit anti-cancer properties by targeting multiple molecular pathways. It was, therefore, of interest to investigate flavokawain C (FKC), a naturally occurring chalcone, which can be isolated from Kava (Piper methysticum Forst) root extract. The aim of this study was to investigate the inhibitory effect of FKC on the growth of HT-29 cells and its underlying mechanism of action. Cell viability of HT-29 cells was assessed by Sulforhodamine B assay after FKC treatment. Induction of apoptosis was examined by established morphological and biochemical assays...

PURPOSE: Malnutrition after mini-gastric bypass (MGB) is a rare and dreaded complication with few data available regarding its surgical management. We aim to report the feasibility, safety, and results of laparoscopic reversal of MGB to normal anatomy (RMGB) in case of severe and refractory malnutrition syndrome after intensive nutritional support (SRMS). METHODS: A 10-year retrospective chart review was performed on patients who underwent RMGB (video included) for SRMS following MGB...

Although cascading effects of top predators can help structure communities, their influence may vary across habitats that differentially protect prey. Therefore, to understand how and to what degree habitat complexity can affect trophic interactions in adjacent habitats, we used a combination of a broad regional-scale survey, manipulative field trials, and an outdoor mesocosm experiment to quantify predator-prey interaction strengths across four trophic levels. Within estuaries of the southeastern USA, bonnethead sharks (Sphyrna tiburo) hunt blue crabs on mudflats and adjacent oyster reefs, two habitats with vastly different aboveground structure...

INTRODUCTION: We sought to assess the impact of surgical wait time (SWT) to robot-assisted radical prostatectomy (RARP) on final pathological outcome. METHODS: A retrospective review of RARP patient records operated between 2006 and 2015 was conducted. SWT was defined as period from prostate biopsy to surgery. Primary outcome was the impact on postoperative Cancer of the Prostate Risk Assessment (CAPRA-S) score. Patients were stratified according to D'Amico risk categories...

Diabetic retinopathy (DR) is a complication secondary to diabetes and is the number one cause of blindness among working age individuals worldwide. Despite recent therapeutic breakthroughs using pharmacotherapy, a cure for DR has yet to be realized. Several clinical trials have highlighted the vital role dyslipidemia plays in the progression of DR. Additionally, it has recently been shown that activation of Liver X receptor (LXRα/LXRβ) prevents DR in diabetic animal models. LXRs are nuclear receptors that play key roles in regulating cholesterol metabolism, fatty acid metabolism and inflammation...

The powder of an Al7075 alloy was prepared by gas atomization. A combination of cellular, columnar, and equiaxed dendritic-like morphology was observed in individual powder particles with continuous layers of intermetallic phases along boundaries. The cells are separated predominantly by high-angle boundaries, the areas with dendritic-like morphology usually have a similar crystallographic orientation. Spark plasma sintering resulted in a fully dense material with a microstructure similar to that of the powder material...

Ti-35Nb-2Zr-0.5O (wt%) alloy was prepared via a powder metallurgy process (cold isostatic pressing of blended elemental powders and subsequent sintering) with the primary aim of using it as a material for bio-applications. Sintered specimens were swaged and subsequently the influence of annealing temperature on the mechanical and structural properties was studied. Specimens were annealed at 800, 850, 900, 950, and 1000°C for 0.5h and water quenched. Significant changes in microstructure (i.e. precipitate dissolution or grain coarsening) were observed in relation to increasing annealing temperature...

OBJECTIVE: This study aimed to evaluate long-term efficacy of low dose cyclosporine A (CsA) in the treatment of resistant proliferative lupus nephritis. METHODS: In this retrospective study, patients with biopsy proven proliferative lupus nephritis who were unresponsive to combination therapy with steroid plus mycophenolate mofetil (MMF) or cyclophosphamide (CYC) and had been treated with CsA were included. Efficacy monitoring was based on the systemic lupus erythematosus (SLE) disease activity index, dose of prednisolone, serum complement, anti-double stranded DNA (anti-dsDNA) titration, urine analysis, proteinuria, creatinine clearance, remission of the renal disease, renal survival and involvement of other organs...

METHODS: This is a cross-sectional study conducted among diabetic patients referring to Ardabil diabetes clinic in Northwest of Iran. Information on sleep quality was collected using Pittsburg Sleep Quality Index (PSQI). A questionnaire was used to collect data on sociodemographic lifestyle factors and psychological distress. This questionnaire was completed through an interview, and clinical information was extracted from patient's record...

Quantitative real-time reverse transcription polymerase chain reaction (RT-PCR) represents a benchmark technology in the detection and quantification of mRNA. Yet, accurate results cannot be realized without proper statistical analysis of RT-PCR data. Here we examine some of the issues concerning RT-PCR experiments that would benefit from rigorous statistical treatment including normalization, quantification, efficiency estimation, and sample size calculations. Examples are used to illustrate the methods.

In this study, we proposed that administration of hippocampal growth hormone in ageing animals with growth hormone deficiency can compensate long-term potentiation and synaptic plasticity in nucleus basalis magnocellularis (NBM)-lesioned rats. Aged male Wistar rats were randomly divided into six groups (seven in each) of sham-operated healthy rats (Cont); NBM-lesioned rats (L); NBM-lesioned rats and intrahippocampal injection of growth hormone vehicle (L + Veh); NBM-lesioned and intrahippocampal injection of growth hormone (10, 20 and 40 µg...

BACKGROUND: Cancer survivors transfused with blood products before reliable screening for hepatitis C virus (HCV) are at risk for infection. This study examined the impact of HCV on neurocognitive function and health-related quality of life (HRQOL) among adult survivors of childhood cancer. METHODS: Neurocognitive testing was conducted for 836 adult survivors of childhood cancer (mean age, 35 years [standard deviation, 7.4 years]; time since diagnosis, 29 years [standard deviation, 6...
