The genetics behind predisposition to small intestinal neuroendocrine tumors (SI-NETs) is largely unknown, but there is growing awareness of a familial form of the disease. We aimed to identify germline mutations involved in the carcinogenesis of SI-NETs. The strategy included next-generation sequencing of exome- and/or whole-genome of blood DNA, and in selected cases tumor DNA, from 24 patients from 15 families with the history of SI-NETs. We identified seven candidate mutations in six genes that were further studied using 215 sporadic SI-NET patients...

PURPOSE: This article examines feature-based nodule description for the purpose of nodule classification in chest computed tomography scanning. METHODS: Three features based on (i) Gabor filter, (ii) multi-resolution local binary pattern (LBP) texture features and (iii) signed distance fused with LBP which generates a combinational shape and texture feature are utilized to provide feature descriptors of malignant and benign nodules and non-nodule regions of interest...

Fetal bovine serum (FBS) is the most commonly used supplement for ex vivo expansion of human mesenchymal stem cells (hMSCs) for bone tissue engineering applications. However, from a clinical standpoint, it is important to substitute animal-derived products according to current Good Manufacturing Practice (cGMP) guidelines. Humanized alternatives to FBS include three categories of products: human serum (HS), human platelet-derivatives (HPD) - including platelet lysate (PL) or releasate (PR), produced by freeze-/thawing or chemical activation of platelet concentrates, respectively; and chemically-defined media (CDM)...

BACKGROUND: Glycoprotein IIb IIIa inhibitors improved short- and long-term outcome when added to primary percutaneous coronary intervention (PPCI) in patients with ST-segment-elevation myocardial infarction (STEMI). We hypothesized that intracoronary eptifibatide infusion via a perfusion catheter improves angiographic and clinical outcome of patients with STEMI undergoing PPCI, versus conventional intracoronary bolus injection. METHODS: Prospectively, we enrolled 80 patients with acute STEMI and thrombolysis in myocardial infarction (TIMI) thrombus grade ≥ 2...

OBJECTIVE: The D prostanoid receptor 1 (DP1), a receptor for prostaglandin D2 (PGD2 ), plays important roles in inflammation and cartilage metabolism. However, its role in the pathogenesis of osteoarthritis (OA) remains unknown. We undertook this study to explore the roles of DP1 in the development of OA and to evaluate the efficacy of a DP1 selective agonist in the treatment of OA. METHODS: We compared the development of aging-associated OA and destabilization of the medial meniscus (DMM)-induced OA in DP1-deficient (DP1-/-) and wild-type (WT) mice...

AIM: To determine the true prevalence of thrombocytosis in children less than 2 years of age with bronchiolitis, its association with risk factors, disease severity and thromboembolic complications. METHODS: A retrospective observational medical chart review of 305 infants aged two years or less hospitalized for bronchiolitis. Clinical outcomes included disease severity, duration of hospital stay, admission to pediatric intensive care unit, or death. They also included complications of thrombocytosis, including thromboembolic complications such as cerebrovascular accident, acute coronary syndrome, deep venous thrombosis, pulmonary embolus, mesenteric thrombosis and arterial thrombosis and also hemorrhagic complications such as bleeding (spontaneous hemorrhage in the skin, mucous membranes, gastrointestinal, respiratory, or genitourinary tracts)...

In this study, transdermal etodolac-loaded cubosomes were developed in order to relieve patient pain and joints stiffness by providing stable etodolac concentration at the targeting sites through controlled drug delivery via the noninvasive skin route with more sustaining and less frequent dosing. Different ratios and percentages of poloxamer 407 and monoolein were used to formulate the cubosomes using emulsification and homogenization processes. The etodolac-loaded cubosomes showed particle size values ranging from 135...

Background: Egypt has the largest hepatitis C virus (HCV) epidemic worldwide. Sofosbuvir is an antiviral drug acting by inhibition of the HCV NS5B polymerase. It has shown high efficacy in combination with several other drugs and has a low reported rate of side effects. Objective: The aim of this prospective cohort study was to assess the safety of sofosbuvir-based treatment regimens used to treat chronic hepatitis C infections and to detect any side effects of sofosbuvir not previously reported. Methods: We studied treatment side effects in 3,000 patients with chronic HCV infection treated with sofosbuvir and ribavirin for 24 weeks or treated by pegylated interferon, sofosbuvir, and ribavirin triple therapy for 12 weeks...

A comparative force degradation high performance thin layer chromatography (HPTLC) method was developed and validated for some H2-receptor antagonists. The studied H2-receptor antagonists were ranitidine (RAN), nizatidine (NIZ) and famotidine (FAM). The degradation behaviors of the studied H2-receptor antagonists were studied under different stress conditions (hydrolytic, thermal and oxidative) conditions as well as storage conditions according to International Conference on Harmonization (ICH) recommendations...

The fabrication of hydroxyapatite-Co-ferrite nanocomposite coatings was performed on stainless steel by chronoamperometry technique. HA-CoFe2O4 nanocomposite films were characterized using X-ray diffraction, scanning electron microscopy, and vibrating sample magnetometer (VSM). The results reveal that CoFe2O4 nanoparticles dispersed within the HA matrix have flake and strip shapes. The magnetic property of the nanocomposite was increased by increasing the concentration of CoFe2O4 and a good saturation magnetization value was found to be 20...

In this study, synthesis, molecular docking and anticancer screening of new series of substituted heterocycles with trimethoxy phenyl scaffold as Combretastatin analogues were described. Substituted pyridines were synthesized via reaction of (E)-3-(dimethylamino)-1-(3,4,5-trimethoxyphenyl)prop-2-en-1-one (2)with active methylene reagents. Substituted pyrimidines were prepared by the reaction of the enaminone (2) with heterocyclic amines and 6-amino thiouracil. Furthermore, a series of pyrazoles substituted with trimethoxyphenyl scaffold were prepared by reaction of the enaminone 2, with selected examples of hydrazonoyl halides...

Hepatitis B virus (HBV) infection is a global health problem. The mechanisms of immune tolerance in HBV infection are still unclear. The host immune response plays a critical role in determining the outcome of HBV infection. Human leukocyte antigen-G (HLA-G) is involved in immunotolerogenic process and infectious diseases. The present study aimed to explore the implication of soluble HLA-G (sHLA-G) and its isoforms in HBV infection. Total sHLA-G (including shedding HLA-G1 and HLA-G5) was analysed by ELISA in 95 chronic HBV patients, 83 spontaneously resolvers and 100 healthy controls...
