Visceral Leishmaniasis (VL), also known as kala-azar in Asian countries, is one of the most significant forms of VL, along with Cutaneous Leishmaniasis (CL) and Mucocutaneous Leishmaniasis (ML). Management of this condition typically entails the use of chemotherapy as the sole therapeutic option.

Most chronic liver diseases progress to liver fibrosis, which, when left untreated, can lead to cirrhosis and hepatocellular carcinoma. MicroRNA (miRNA)-targeted therapeutics have become attractive approaches to treat diseases. In this study, we investigated the therapeutic effect of miR-155 inhibition in the bile duct ligation (BDL) mouse model of liver fibrosis and evaluated the role of miR-155 in chronic liver fibrosis using miR-155-deficient (miR-155 knockout [KO]) mice.

Aim And Objective: To investigate the effect of dental environment stressors and coping mechanisms on perceived stress in postgraduate dental students.
Materials And Methods: This cross-sectional study enrolled 250 postgraduate students from four dental colleges. Modified dental environment stress (DES) questionnaire was used to study the dental environment-related stressors, perceived stress score (PSS) to measure the extent of stress perception, and brief COPE (BC) scale to measure the use of various coping strategies deployed to combat stress.

microRNAs (miRs) are small regulatory RNAs that are frequently deregulated in liver disease. Liver fibrosis is characterized by excessive scarring caused by chronic inflammatory processes. In this study, we determined the functional role of miR-132 using a locked nucleic acid (LNA)-anti-miR approach in liver fibrosis.

In this study we tested the hypothesis that miR-155 is an important regulator of steatohepatitis and fibrosis pathways.

The miR-34 family is thought to play a role in tumor suppression, but the exact mechanism of their action in HNSCC is not well understood. Moreover, the impact of chromosomal changes and mutation status on miR-34a expression remains unknown.

Here we generate a humanized (Hu)-mouse melanoma model by injecting fetal liver-derived CD34 cells and implanting autologous thymus in immune-deficient NOD-scid IL2Rγ (NSG) mice. Reconstituted Hu-mice are challenged with HLA-matched melanomas and treated with anti-PD-1, which results in restricted tumor growth but not complete regression.

In this study, we demonstrate a new role of microRNA (miR)-208a in ALI. ALI was induced in wild-type (WT) and miR-208a knockout (KO) mice by CCl administration.

Because autophagy and exosome biogenesis share common elements, we hypothesized that increased exosome production in ALD may be linked to disruption of autophagic function. We found impaired autophagy both in ALD and alcoholic hepatitis (AH) mouse models and human livers with ALD as indicated by increased hepatic p62 and LC3-II levels.

Although it has been shown that EVs can play an active role in cellular communication and different stages of cancer progression, the role of EVs in oral squamous cell carcinoma (OSCC) cancer pathogenesis, especially in the crosstalk of cancer cells with immune cells is unknown. Here, we present a detailed analysis of findings regarding the profile of EVs in OSCC and the role of EVs and associated miRNAs in the crosstalk of malignant cells with monocytes.

They act by regulating the expression of multiple immune genes, thus, are the important elements to the complex immune regulatory network. Deregulated expression of specific miRNAs can lead to potential autoimmunity, immune tolerance, hyper-inflammatory phenotype, and cancer initiation and progression.

Gingival enlargement is a very common side effect associated with the administration of several drugs, mainly anticonvulsants, calcium channel blockers (CCBs), and immunosuppressants. Amlodipine (a CCB) is a safe antihypertensive drug with a longer duration of action. Gingival enlargement induced by amlodipine is less prevalent among CCBs.
