Peroxidases are a group of heterogeneous family of enzyme that plays diverse biological functions. Ascorbate peroxidase is a redox enzyme that is reduced by trypanothione, which plays a central role in the redox defence system of Leishmania. In view of developing new and novel therapeutics, we have performed in silico studies in order to search for ligand library and identification of new drug candidates and its physiological role against promastigotes and intracellular amastigotes of Leishmania donovani. Our results demonstrated that the selected inhibitor ZINC96021026 has significant anti-leishmanial effect and effectively killed both free and intracellular forms of the parasite. ZINC96021026 was found to be identical to ML-240, a selective inhibitor of Valosin-containing protein (VCP) or p97, a member of AAA-ATPase protein family which was derived from the scaffold of DBeQ, targeting the D2-ATPase domain of the enzyme. ZINC96021026 (ML-240) thus have broad range of cellular functions, thought to be derived from its ability to unfold proteins or disassemble protein complexes besides inhibiting the ascorbate peroxidase activity. ML-240 may inhibits the parasite's ascorbate peroxidase leading to extensive apoptosis and inducing generation of reactive oxygen species. Taken together, our results demonstrated that ML-240 could be an attractive therapeutic option for treatment against leishmaniasis.

Earlier genetic and inhibitor studies have shown that epigenetic regulation of gene expression is critical for malaria parasite survival in multiple life stages and a promising target for new anti-malarials. We therefore evaluated the activity of 350 diverse epigenetic inhibitors against multiple stages of Plasmodium falciparum. We observed ≥90% inhibition at 10 μM for 28% of compounds against asexual blood stages and early gametocytes, of which a third retained ≥90% inhibition at 1 μM.

Cyclophilins play a key role in the lifecycle of coronaviruses. Alisporivir (Debio 025) is a non-immunosuppressive analogue of cyclosporin A with potent cyclophilin inhibition properties. Alisporivir reduced SARS-CoV-2 RNA production in a dose-dependent manner in VeroE6 cell line, with an EC₅₀ of 0.46±0.04 μM. Alisporivir inhibited a post-entry step of the SARS-CoV-2 lifecycle. These results justify that a proof-of-concept Phase 2 trial be rapidly conducted with alisporivir in patients with SARS-CoV-2 infection.

Google has made it easier to join the company's Advanced Protection Program, which is designed to stop the most sophisticated hackers from breaking into your Gmail account. Before you needed two security keys to enroll. Now you just need a smartphone.

The FBI seizes the internet domain to WeLeakInfo.com, a site that was cataloging billions of records, such as email addresses and passwords, from more than 10,300 data breaches at various companies and service providers.

The stunning allegation reportedly comes from a forensic analysis Amazon CEO Jeff Bezos commissioned to determine the culprit behind the hack, which resulted in his private photos ending up in the hands of the National Enquirer.

The records involved conversation logs between Microsoft support agents and customers across the globe, dating back to 2005. Most of the records were redacted of customer contact information, but not all.

On Tuesday, Avast responded to a PCMag-Motherboard investigation into the company's browser history collection practices, saying it was entirely legal. Avast users should expect to see a prompt from the antivirus products, asking them to consent to the data harvesting.

BACKGROUND:

The ability of the decades-old Boston and Philadelphia criteria to accurately identify infants at low risk for serious bacterial infections has not been recently reevaluated.

BACKGROUND:

Approximately 25% of children with concussion have persistent postconcussive symptoms (PPCS) with resultant significant impacts on quality of life. Melatonin has significant neuroprotective properties, and promising preclinical data suggest its potential to improve outcomes after traumatic brain injury. We hypothesized that treatment with melatonin would result in a greater decrease in PPCS symptoms when compared with a placebo.

BACKGROUND:

The association of dietary fat distribution with markers of subclinical atherosclerosis during early life is unknown. We examined whether success in achieving the main target of an infancy-onset dietary intervention based on the distribution of dietary fat was associated with aortic and carotid intima-media thickness (IMT) and distensibility from childhood to young adulthood.

BACKGROUND:

In the United States, transgender youth are at especially high risk for HIV infection. Literature regarding HIV prevention strategies for this vulnerable, often-hidden population is scant. Before effective, population-based HIV prevention strategies may be adequately developed, it is necessary to first enhance the contextual understanding of transgender youth HIV risk and experiences with HIV preventive services.

OBJECTIVES:

Infantile hemangiomas (IHs) are common; some cases require timely referral and treatment to prevent complications. We developed and validated a reliable instrument for timely and adequate referral of patients with IH to experts by nonexpert primary physicians.
