Immunoinhibitory effects of anti-tuberculosis therapy induce the host vulnerability to tuberculosis recurrence.

The host immune responses play a pivotal role in the establishment of long-term memory responses, which effectively aids in infection clearance. However, the prevailing anti-tuberculosis therapy, while aiming to combat tuberculosis (TB), also debilitates innate and adaptive immune components of the host. In this study, we explored how the front-line anti-TB drugs impact the host immune cells by modulating multiple signaling pathways and subsequently leading to disease relapse.

Antibacterial activity of medicinal plants against ESKAPE: An update.

Antibiotic resistance has emerged as a threat to global health, food security, and development today. Antibiotic resistance can occur naturally but mainly due to misuse or overuse of antibiotics, which results in recalcitrant infections and Antimicrobial Resistance (AMR) among bacterial pathogens. These mainly include the MDR strains (multi-drug resistant) of ESKAPE (, , , , , and species).

Inositol hexa phosphoric acid (phytic acid), a nutraceuticals, attenuates iron-induced oxidative stress and alleviates liver injury in iron overloaded mice.

Inositol hexa phosphoric acid (IP6) or Phytic acid, a natural antioxidant of some leguminous plants, known to act as a protective agent for seed storage in plants by suppressing iron catalyzed oxidative process. Following the same mechanism, we have tested the effect of IP6 on iron overloaded in vitro oxidative stress, and studied it's in vivo hepatoprotective ability in iron-dextran (injection)-induced iron overloaded liver injury in mice (intraperitoneal). Our results showed that IP6 had in vitro iron chelation (IC 38.

Synthesis of multi ring-fused imidazo [1,2- a]isoquinoline-based fluorescent scaffold as anti-Herpetic agent.

Background: Natural product-inspired synthesis is a key incorporation in modern diversity-oriented synthesis to yield biologically novel scaffold. Inspired by β-carboline fused system, we have designed molecules with multi ring fused scaffold by modifying the tricyclic pyrido[3,4- b]indole ring with imidazo[1,2- a]isoquinoline.

Methods: A highly convergent approach with new C-N and C-C bond formation to synthesize multiring fused complex scaffold imidazo[1,2- a]isoquinolinies as fluorophores.

Prevalence of hepatitis E virus infection in West Bengal, India: a hospital-based study.

India is an endemic zone for hepatitis E virus (HEV), which is associated with both epidemic and sporadic infections. In West Bengal, only two hepatitis E outbreaks have been studied to date. However, sporadic cases of HEV infection also occur during inter-epidemic periods.

An indole alkaloid from a tribal folklore inhibits immediate early event in HSV-2 infected cells with therapeutic efficacy in vaginally infected mice.

Herpes genitalis, caused by HSV-2, is an incurable genital ulcerative disease transmitted by sexual intercourse. The virus establishes life-long latency in sacral root ganglia and reported to have synergistic relationship with HIV-1 transmission. Till date no effective vaccine is available, while the existing therapy frequently yielded drug resistance, toxicity and treatment failure.

Phylogenetic analysis of hepatitis e virus in northwest India.

Genotyping and subtyping are important to understand epidemiology of the hepatitis E virus so as to improve control measures to prevent transmission of virus in the community. Hence, the aim of the current study was to identify the prevalent HEV genotypes in Rajasthan in acute sporadic hepatitis E cases with varying degree of liver failure. We studied hepatitis E virus (HEV) isolates from hospitalized patients in Rajasthan, western India.

Contribution of hepatitis E virus in acute sporadic hepatitis in north western India.

Background & Objectives: Hepatitis E virus (HEV) causes acute viral hepatitis. Majority of the documented studies on hepatitis E have been focused on the incidence of this disease in northern and south central India. Limited data are available on HEV infection among acute sporadic hepatitis cases in north western India.

Dynamics of HEV viremia, fecal shedding and its relationship with transaminases and antibody response in patients with sporadic acute hepatitis E.

Background: There is paucity of data regarding duration of fecal excretion and viremia on sequential samples from individual patients and its correlation with serum transaminases and antibody responses in patients with acute hepatitis E. This prospective study was undertaken at a tertiary care center in Northern India over 15 months. Only those patients of sporadic acute hepatitis E who were in their first week of illness and followed up weekly for liver function tests, IgM anti HEV antibody and HEV RNA in sera and stool were included.
