Oligoclonal band versus chitinase-3-like protein-1 in CSF of newly diagnosed relapsing remitting multiple sclerosis.

Multiple sclerosis (MS) is a chronic autoimmune-mediated demyelinating disease of the central nervous system (CNS) that is usually associated with varying degrees of progressive disability. Chitinase-3-like protein-1 (CHI3L1) has attracted growing attention as a marker of ongoing inflammation and oncogenic transformation. The aim of this work was to assess the diagnostic accuracy of CHI3L1 versus IgG oligoclonal bands (OCBs) in the cerebrospinal fluid (CSF) of newly diagnosed relapsing remitting MS (RRMS) patients to throw light on a new simpler non subjective potential diagnostic marker in MS.

Prognostic Value of PD-L1 Immunohistochemical Marker in Gastric Carcinoma and Its Correlation with HER2 Status.

Objective: Programmed death-ligand 1 (PD-L1) and human epidermal growth factor receptor 2 (HER2) are currently considered as prognostic markers and therapeutic targets in many human cancers. This study aims to evaluate immunohistochemical (IHC) expression of PD-L1 in gastric cancer (GC) and explore its prognostic role in terms of association with HER2 expression, different clinico-pathological variables, in particular density and cluster designation (CD)8 positivity in tumor infiltrating lymphocytes (TILs) and with patients' disease-free and overall survival (DFS, OS).

Methods: This retrospective cohort study included 111 diagnosed primary GC patients who underwent surgical resection at the Gastrointestinal Surgery Center (GISC), Faculty of Medicine, Mansoura University, Egypt.

Subtyping of high grade serous ovarian carcinoma: histopathological and immunohistochemical approach.

Background: High-grade serous ovarian carcinoma (HGSOC) is classified into four molecular subtypes; mesenchymal, proliferative, immunoreactive, and differentiated, with suggested different prognosis. Addressing the presence of histopathological and immunohistochemical differences in HGSOC that parallel the molecular subtypes can help in tailoring the management protocol to improve therapeutic response and patient outcome.

Methods: This retrospective study was conducted on 85 specimens for cases of HGSOC.

Sex dichotomy in the course of experimental latent toxoplasmosis.

Toxoplasma gondii is an opportunistic zoonotic protozoan that exceeds neurological and congenital impact sequence to reactivating latent toxoplasmosis especially under immunosuppression. Sex-associated hormones influence the severity of Toxoplasma infection. Thus, our study aimed to compare toxoplasmosis associated morbidity in both male and female mice and to monitor the response to anti-Toxoplasma therapeutics fortified with sex hormones in comparison to presently used drugs.

The role of mesenchymal stem cells in chemotherapy-induced gonadotoxicity.

Background: The therapeutic potential of bone marrow-derived mesenchymal stem cells (BM-MSCs) against cisplatin-induced nephrotoxicity has been reported, however, its efficacy in gonadotoxicity still has not been addressed.

Glypican-3 (GPC3) is a member of the membrane-bound heparin sulfate proteoglycans. E-cadherin is an adhesive receptor that is believed to act as a tumor suppressor gene. Many studies had investigated E-cadherin expressions in colorectal carcinoma (CRC) while only one study had investigated GPC3 expression in CRC.

Cisplatin-induced testicular toxicity in rats: the protective effect of arjunolic acid.

In the present study, the effect of arjunolic acid on testicular damage induced by intraperitoneal injection of rats with 7 mg/kg cisplatin was studied. Cisplatin induced a significant reduction in testicular weights, plasma testosterone, and testicular reduced glutathione levels in addition to a significant elevation of testicular malondialdehyde levels and testicular gene expressions of inducible nitric oxide synthase (iNOS), tumor necrosis factor-α (TNF-α), and p38 mitogen-activated protein kinase (MAPK) when compared with the control group (p < 0.05).

Valproate-induced liver injury: modulation by the omega-3 fatty acid DHA proposes a novel anticonvulsant regimen.

Background: The polyunsaturated, ω-3 fatty acid, docosahexaenoic acid (DHA), claims diverse cytoprotective potentials, although via largely undefined triggers. Thus, we currently first tested the ability of DHA to ameliorate valproate (VPA)-evoked hepatotoxicity, to modulate its anticonvulsant effects, then sought the cellular and molecular basis of such actions. Lastly, we also verified whether DHA may kinetically alter plasma levels/clearance rate of VPA.

Matrix metalloproteinase-13 expression in the progression of colorectal adenoma to carcinoma : Matrix metalloproteinase-13 expression in the colorectal adenoma and carcinoma.

Most colorectal carcinomas (CRCs) are considered to arise from conventional adenoma based on the concept of the adenoma-carcinoma sequence. Matrix metalloproteinases (MMPs) are known to be overexpressed as normal mucosa progresses to adenomas and carcinomas. There has been little previous investigation about MMP-13 expression in adenoma-carcinoma sequence.
