Epidemiological analysis of Leishmania tropica strains and giemsa-stained smears from Syrian and Turkish leishmaniasis patients using multilocus microsatellite typing (MLMT).

Turkey is located in an important geographical location, in terms of the epidemiology of vector-borne diseases, linking Asia and Europe. Cutaneous leishmaniasis (CL) is one of the endemic diseases in a Turkey and according to the Ministry Health of Turkey, 45% of CL patients originate from Şanlıurfa province located in southeastern Turkey. Herein, the epidemiological status of CL, caused by L.

Involvement of heparanase in the pathogenesis of acute kidney injury: nephroprotective effect of PG545.

Despite the high prevalence of acute kidney injury (AKI) and its association with increased morbidity and mortality, therapeutic approaches for AKI are disappointing. This is largely attributed to poor understanding of the pathogenesis of AKI. Heparanase, an endoglycosidase that cleaves heparan sulfate, is involved in extracellular matrix turnover, inflammation, kidney dysfunction, diabetes, fibrosis, angiogenesis and cancer progression.

Oral Administration of β-Glucosylceramide for the Treatment of Insulin Resistance and Nonalcoholic Steatohepatitis: Results of a Double-Blind, Placebo-Controlled Trial.

β-glucosylceramide (GC) is a naturally occurring glycosphingolipid that was shown to improve hepatic steatosis, steatohepatitis, and insulin resistance in animal models of nonalcoholic fatty liver disease. In this study, we evaluated the safety and efficacy of oral administration of GC in subjects with nonalcoholic steatohepatitis (NASH). Twenty-three patients with biopsy proven NASH were enrolled in a double-blind, placebo-controlled trial.

Impaired liver regeneration is associated with reduced cyclin B1 in natural killer T cell-deficient mice.

Background: It has been shown that the proportion of natural killer T cells is markedly elevated during liver regeneration and their activation under different conditions can modulate this process. As natural killer T cells and liver injury are central in liver regeneration, elucidating their role is important.

Methods: The aim of the current study is to explore the role of natural killer T cells in impaired liver regeneration.

Features of Patients With Hereditary Mixed Polyposis Syndrome Caused by Duplication of GREM1 and Implications for Screening and Surveillance.

Hereditary mixed polyposis syndrome is a rare colon cancer predisposition syndrome caused by a duplication of a noncoding sequence near the gremlin 1, DAN family BMP antagonist gene (GREM1) originally described in Ashkenazi Jews. Few families with GREM1 duplications have been described, so there are many questions about detection and management. We report 4 extended families with the duplication near GREM1 previously found in Ashkenazi Jews; 3 families were identified at cancer genetic clinics in Israel and 1 family was identified in a cohort of patients with familial colorectal cancer.

Oncotype Dx recurrence score among BRCA1/2 germline mutation carriers with hormone receptors positive breast cancer.

Gene expression assays are widely used to predict risk of recurrence in early breast cancer (BC). We report the 21-gene expression assay (Oncotype Dx) recurrence score (RS) distribution of 27 BRCA carriers with estrogen receptor (ER) positive BCs, identified at Hadassah Medical Center, combined with 2 previous studies. Treatment decision and outcomes of the 27 BRCA carriers were compared with an Israeli cohort of 1594 patients published recently.

Porphyromonas gingivalis Promotes Unrestrained Type I Interferon Production by Dysregulating TAM Signaling via MYD88 Degradation.

Whereas type I interferons (IFNs-I) were proposed to be elevated in human periodontitis, their role in the disease remains elusive. Using a bacterial-induced model of murine periodontitis, we revealed a prolonged elevation in IFN-I expression. This was due to the downregulation of TAM signaling, a major negative regulator of IFN-I.

Analysis of Leukocytes in Oral Mucosal Tissues.

The oral mucosa is constantly exposed to an immense amount of microorganisms, while some colonize the various anatomical niches existing in the oral cavity. To deal with such a complex challenge, the oral mucosal immune system must tolerate commensal microorganisms but prevent invasion of pathogens. Such activity is likely to be achieved by a wide range of mechanisms that could be similar or different to those employed by other mucosal tissues.

Recurrent TP53 missense mutation in cancer patients of Arab descent.

Hereditary cancer comprises more than 10% of all breast cancer cases. Identification of germinal mutations enables the initiation of a preventive program that can include early detection or preventive treatment and may also have a major impact on cancer therapy. Several recurrent mutations were identified in the BRCA1/2 genes in Jewish populations however, in other ethnic groups in Israel, no recurrent mutations were identified to date.

Liver involvement in Gaucher disease - Review and clinical approach.

Gaucher disease (GD), one of the most prevalent lysosomal storage diseases, is associated with glucocerebroside accumulation in cells of the monocyte-macrophage system in various organs, including the liver. Evaluating and managing liver disease in patients with Gaucher disease may be challenging. While hepatic involvement is common in Gaucher disease, its severity, and clinical significance span a wide spectrum, ranging from sub-clinical involvement to liver cirrhosis with its associated complications including portal hypertension.

The gut-kidney axis in chronic renal failure: A new potential target for therapy.

Evidence is accumulating to consider the gut microbiome as a central player in the gut-kidney axis. Microbiome products, such as advanced glycation end products, phenols, and indoles, are absorbed into the circulation but are cleared by normal-functioning kidneys. These products then become toxic and contribute to the uremic load and to the progression of chronic kidney failure.

Pseudomonal Biofilm Topographic Distribution on Tympanostomy Tubes: An In Vitro Model.

In vitro growth of Pseudomonas aeruginosa biofilm on tympanostomy tubes showed that in Armstrong T-tubes, biofilm colonies were mainly located in the perpendicular junction between the body and the flanges, but in Paparella-type tube, they concentrated on the round rims. These "weakness" zones can be the future target areas for geometry changes, and can be specifically coated with antibiofilm materials.

Ischemic Gastropathic Ulcer Mimics Gastric Cancer.

Gastric ulcer due to mesenteric ischemia is a rare clinical finding. As a result, few reports of ischemic gastric ulcers have been reported in the literature. The diagnosis of ischemic gastropathy is seldom considered in patients presenting with abdominal pain and gastric ulcers.

Protection by Nitric Oxide Donors of Isolated Rat Hearts Is Associated with Activation of Redox Metabolism and Ferritin Accumulation.

Preconditioning (PC) procedures (ischemic or pharmacological) are powerful procedures used for attaining protection against prolonged ischemia and reperfusion (I/R) injury, in a variety of organs, including the heart. The detailed molecular mechanisms underlying the protection by PC are however, complex and only partially understood. Recently, an 'iron-based mechanism' (IBM), that includes de novo ferritin synthesis and accumulation, was proposed to explain the specific steps in cardioprotection generated by IPC.

Associations of socioeconomic position in childhood and young adulthood with cardiometabolic risk factors: the Jerusalem Perinatal Family Follow-Up Study.

Background: Several stages in the life course have been identified as important to the development of cardiovascular disease. This study aimed to assess the associations of childhood and adulthood socioeconomic position (SEP) and social mobility with cardiometabolic risk factors (CMRs) later in life.

Methods: We conducted follow-up examinations of 1132 offspring, aged 32, within a population-based cohort of all births in Jerusalem from 1974 to 1976.

Bi-functional prodrugs of 5-aminolevulinic acid and butyric acid increase erythropoiesis in anemic mice in an erythropoietin-independent manner.

Anemia is a major cause of morbidity and mortality worldwide resulting from a wide variety of pathological conditions. In severe cases it is treated by blood transfusions or injection of erythroid stimulating agents, e.g.

Oral immune therapy: targeting the systemic immune system via the gut immune system for the treatment of inflammatory bowel disease.

Inflammatory bowel diseases (IBD) are associated with an altered systemic immune response leading to inflammation-mediated damage to the gut and other organs. Oral immune therapy is a method of systemic immune modulation via alteration of the gut immune system. It uses the inherit ability of the innate system of the gut to redirect the systemic innate and adaptive immune responses.

RNF20 Links Histone H2B Ubiquitylation with Inflammation and Inflammation-Associated Cancer.

Factors linking inflammation and cancer are of great interest. We now report that the chromatin-targeting E3 ubiquitin ligase RNF20/RNF40, driving histone H2B monoubiquitylation (H2Bub1), modulates inflammation and inflammation-associated cancer in mice and humans. Downregulation of RNF20 and H2Bub1 favors recruitment of p65-containing nuclear factor κB (NF-κB) dimers over repressive p50 homodimers and decreases the heterochromatin mark H3K9me3 on a subset of NF-κB target genes to augment their transcription.

The Complex Role of Anticoagulation in Cirrhosis: An Updated Review of Where We Are and Where We Are Going.

Venous thromboembolism (VTE) in cirrhotic patients is an increasingly encountered problem in the daily clinical practice; there is still a debate on the ideal measures to be followed for prophylaxis and treatment of VTE among this population. Although traditionally, liver cirrhosis has been considered a disease with hypocoagulability state and increasing bleeding tendency due to severe homeostatic disruption in liver disease, until recently there is increasing awareness and evidence that cirrhotic patients are not completely protected from thrombotic events although they have an elevated international normalized ratio and auto anticoagulation. Furthermore, hypercoagulability is now an increasingly recognized aspect of chronic liver disease (CLD), and the bleeding risk of VTE prophylaxis and treatment remains unclear.

microRNAs and Endometrial Pathophysiology.

Embryo implantation requires a reciprocal interaction between the blastocyst and endometrium and is associated with complex regulatory mechanisms. Since their discovery, microRNAs became prominent candidates providing missing links for many biological pathways. In recent years, microRNAs were implicated as one of the important players in regulation of various biological and physiological endometrial related processes.

Sleep Disorders in Postmenopausal Women.

One of the core symptoms of the menopausal transition is sleep disturbance. Peri-menopausal women often complain of difficulties initiating and/or maintaining sleep with frequent nocturnal and early morning awakenings. Factors that may play a role in this type of insomnia include vasomotor symptoms, changing reproductive hormone levels, circadian rhythm abnormalities, mood disorders, coexistent medical conditions, and lifestyle.

Parent-of-Origin Effects of the APOB Gene on Adiposity in Young Adults.

Loci identified in genome-wide association studies (GWAS) of cardio-metabolic traits account for a small proportion of the traits' heritability. To date, most association studies have not considered parent-of-origin effects (POEs). Here we report investigation of POEs on adiposity and glycemic traits in young adults.
