SARS-CoV-2 Persistent Viral Shedding in the Context of Hydroxychloroquine-Azithromycin Treatment.

SARS-CoV-2 nasopharyngeal shedding contributes to the spread of the COVID-19 epidemic. Among 3271 COVID-19 patients treated at the Hospital University Institute Méditerranée Infection, Marseille, France from 3 March to 27 April 2020, tested at least twice by qRT-PCR, the median SARS-CoV-2 nasopharyngeal shedding duration was 6 days (range 2-54 days). Compared with short shedders (qRT-PCR positivity < 10 days), 34 (1.04%) persistent shedders (qRT-PCR positivity ≥ 17 days; mean ± SD: 23.3 ± 3.8 days) were significantly older, with associated comorbidities, exhibiting lymphopenia, eosinopenia, in

Crosstalk between hypoxic cellular micro-environment and the immune system: a potential therapeutic target for infectious diseases.

There are overwhelming reports on the promotional effect of hypoxia on the malignant behavior of various forms of cancer cells. This has been proposed and tested exhaustively in the light of cancer immunotherapy. However, there could be more interesting functions of a hypoxic cellular micro-environment than malignancy. There is a highly intricate crosstalk between hypoxia inducible factor (HIF), a transcriptional factor produced during hypoxia, and nuclear factor kappa B (NF-κB) which has been well characterized in various immune cell types. This important crosstalk shares common activating an

Nucleotide Metabolism in Health and Disease.

Nucleotide metabolism is a fundamental biochemical process, providing the building blocks for DNA and RNA synthesis while driving critical cellular functions like energy transfer, signal transduction, and coenzyme synthesis. The precise regulation of nucleotide de novo synthesis, salvage, and degradation pathways is imperative for maintaining genomic stability and tissue homeostasis. Aberrations in these networks are increasingly recognized as primary drivers in various pathologies; notably, cancer cells exploit metabolic-functional reprogramming to enable rapid proliferation and therapeutic r

PURPOSE: This systematic review was performed to assess the potential influence of medication-induced salivary changes on the development of medication-related osteonecrosis of the jaw (MRONJ). METHODS: An electronic search was conducted using PubMed, Web of Science, Cochrane, and Embase databases for articles published up to June 2023. A risk of bias assessment was performed according to the modified Newcastle-Ottawa Scale (NOS). Due to the heterogeneity of the selected studies in relation to the type of medications and outcomes evaluated, a meta-analysis could not be performed. RESULTS: Th

Decoding the molecular mechanisms of pyroptosis and its therapeutic development prospects.

Pyroptosis is an emerging form of inflammatory programmed cell death primarily mediated by the gasdermin protein family, characterized by cell swelling, membrane pore formation, and the release of pro-inflammatory cytokines such as IL-1β and IL-18. This mode of cell death has garnered significant attention due to its critical involvement in a variety of diseases, including cancer, cardiovascular disorders, autoimmune diseases, and metabolic syndromes, positioning it as a promising therapeutic target. Despite advances, the complexity of pyroptosis regulation and its dual roles in disease pathog

Targeting phosphatidylinositol-3-kinase pathway for the treatment of Philadelphia-negative myeloproliferative neoplasms.

Myeloproliferative neoplasms (MPN) are a diverse group of chronic hematological disorders that involve unregulated clonal proliferation of white blood cells. Sevearl of them are associated with mutations in receptor tyrosine kinases or cytokine receptor associated tyrosine kinases rendering them independent of cytokine-mediated regulation. Classically they have been broadly divided into BCR-ABL1 fusion + ve (Ph + ve) or -ve (Ph-ve) MPNs. Identification of BCR-ABL1 tyrosine kinase as a driver of chronic myeloid leukemia (CML) and successful application of small molecule inhibitors of the tyrosi
