Recent Advances in Immunotherapy for the Treatment of Malignant Melanoma.

Malignant melanoma is one of the most worrisome malignancies due to its fast dissemination and early formation of metastases in multiple sites throughout the body. Despite the intensive efforts made in the last decades, the use of standard therapeutic strategies, including chemotherapy and radiotherapy, has not led to a substantial improvement in clinical outcomes, mainly because of the intrinsic resistance of melanomas to these treatment modalities. Therefore, in recent years, numerous studies have focused on the possibility of boosting the clinical responses of melanoma patients by using novel immunotherapeutic agents.

STAT signaling as a target for intervention: from cancer inflammation and angiogenesis to non-coding RNAs modulation.

As a landmark, scientific investigation in cytokine signaling and interferon-related anti-viral activity, signal transducer and activator of transcription (STAT) family of proteins was first discovered in the 1990s. Today, we know that the STAT family consists of several transcription factors which regulate various molecular and cellular processes, including proliferation, angiogenesis, and differentiation in human carcinoma. STAT family members play an active role in transducing signals from cell membrane to nucleus through intracellular signaling and thus activating gene transcription.

Electrochemical Multiplexed Paper Nanosensor for Specific Dengue Serotype Detection Predicting Pervasiveness of DHF/DSS.

The serotype-specific early detection of dengue fever is very effective in predicting the pervasiveness of fatal infections such as dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). This fever results from reinfection (secondary) with a serotype of the dengue virus, which is different from the serotype involved in primary infection. Hence, the present work was aimed to develop a multiplexed electrochemical paper-based analytical device (ePAD) consisting of graphene oxide-silicon dioxide (GO-SiO) nanocomposites to detect the specific type of dengue virus (DENV).

Epidemiology, diagnosis & treatment of non-tuberculous mycobacterial diseases.

Non-tuberculous mycobacteria (NTM) are ubiquitously present in the environment, but NTM diseases occur infrequently. NTM are generally considered to be less virulent than Mycobacterium tuberculosis, however, these organisms can cause diseases in both immunocompromised and immunocompetent hosts. As compared to tuberculosis, person-to-person transmission does not occur except with M.

Involvement of the toll-like receptors-2/nuclear factor-kappa B signaling pathway in atherosclerosis induced by high-fat diet and zymosan A in C57BL/6 mice.

Objective: Accumulated evidence reported a link between the immune system, microbial infection, and the development of atherosclerosis. Excess intake of high-fat diet (HFD) increases blood lipid levels and induces inflammatory pathways whereas zymosan A (Zym), a microbial component, mediates inflammatory response through the stimulation of specific ligand of toll-like receptors (TLRs) of the immune system. The current research work was aimed to evaluate the mechanism behind atherosclerosis mediated by HFD and Zym in C57BL/6 mice.
