Initiation of combined antiretroviral therapy confers suboptimal beneficial effects on neurovascular function in people with HIV.

Introduction: Due to advances in combined anti-retroviral treatment (cART), there is an increased burden of age-related cerebrovascular disease (CBVD), in people living with HIV (PWH). The underlying CNS injury can be assessed by measuring cerebral blood flow (CBF) and cerebrovascular reactivity (CVR).

Methods: 35 treatment-naïve PWH and 53 HIV negative controls (HC) were enrolled in this study.

Sulforaphane prevents the reactivation of HIV-1 by suppressing NFκB signaling.

Despite more than 20 years of combination antiretroviral therapy (cART), complete eradication of HIV remains a daunting task. While cART has been very effective in limiting new cycles of infection and keeping viral load below detectable levels with partial restoration of immune functions, it cannot provide a cure. Evidently, the interruption of cART leads to a quick rebound of the viral load within a few weeks.

Efficacy and Safety of Molnupiravir in Mild COVID-19 Patients in India.

Background At the peak of the coronavirus disease 2019 (COVID-19) pandemic, the need for an orally administered agent to prevent the progression of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection became increasingly evident, which was the impetus behind our investigations with molnupiravir. Molnupiravir has been shown to be effective in preventing hospitalizations and/or clinical complications in patients with mild-to-moderate COVID-19. In this study, we evaluate the efficacy and safety of molnupiravir in Indian patients with mild SARS-CoV-2 infection and at least one risk factor for disease progression (CTRI/2021/05/033739).

To Assess the Effect of Dsme on Hba1c Levels in Diabetic Patients.

Unlabelled: Diabetes mellitus (DM) is a chronic metabolic disease with debilitating complications. Diabetic Patients should follow self-care activities like healthy diet, physical activity, self-monitoring of blood glucose, treatment compliance in order to achieve good glycaemic control, control the progression of the disease, reduce complications, and quality of life improvement. We aimed to assess the effect of diabetes self-management education program on HbA1c levels in patients with diabetes.

Human immunodeficiency virus-1 Tat exerts its neurotoxic effects by downregulating Sonic hedgehog signaling.

We previously showed that HIV-1 can alter the expression of tight junction proteins by downregulating Sonic hedgehog (Shh) signaling, thereby disrupting blood-brain barrier (BBB) integrity. In this study, we employed a conditional, CNS specific, Tat transgenic murine model to investigate if HIV-Tat exerts its neurotoxic effects by downregulating Shh signaling. Results indicate that Tat + mice exhibit significantly reduced expression of Shh and Gli1.

Methods: Patients' health-related data including age, gender, symptomatology, associated co-morbidities, laboratory test results and HRCT results were collected.

Results: The radiologic findings showed ground glass opacities (GGOs) was the most common manifestation.

Complete Blood-count-based Inflammatory Score (CBCS) of COVID-19 Patients at Tertiary Care Center.

Context: Inflammation is a significant factor driving the rise of multiple cases of viral pneumonia, including COVID-19 infection. Peripheral white blood cells (WBCs), the neutrophil (NEU)-to-lymphocyte (LYM) ratio (NLR), the platelet-to-lymphocyte (PLR) ratio, and hemoglobin (Hb) are markers of systematic inflammatory reaction and often predict disease severity.

Objective: The current study intended to examine the prognostic importance of hemoglobin (Hb), total leukocyte count (TLC), absolute neutrophile count (ANC), absolute lymphocyte count (ALC), NLR, d-NLR [derived NLR = ANC/(WBC-ANC)], absolute platelet count (APC), and PLR, based on complete blood counts (CBCs) for COVID-19 patients.

Spectroscopic Signatures and the Cation-π Interaction in Conformational Preferences of the Neurotransmitter Dopamine in Aqueous Solution.

The precise determination of the neurotransmitter dopamine's conformational preferences in aqueous solution is crucial for understanding its neurobiological function. The first principle Møller-Plesset perturbation theory (MP2) and dispersion corrected density functional theory (DFT-D3) methods, employing the basis set aug-cc-pVDZ(/pVTZ), are used to reinvestigate the nine lowest-energy (isolated) structures of protonated dopamine (DAH) in both gas and aqueous phases. DAH trans isomer is found higher in energy than lowest-energy gauche isomer (g + 1) by 6.

Novel Mechanism of Microvesicle Regulation by the Antiviral Protein Tetherin During HIV Infection.

Background Microvesicles are cell membrane-derived vesicles that have been shown to augment inflammation. Specifically, monocyte-derived microvesicles (MDMVs), which can express the coagulation protein tissue factor, contribute to thrombus formation and cardiovascular disease. People living with HIV experience higher prevalence of cardiovascular disease and also exhibit increased levels of plasma microvesicles.

Cognitive Improvement by Vorinostat through Modulation of Endoplasmic Reticulum Stress in a Corticosterone-Induced Chronic Stress Model in Mice.

Chronic stress is the leading cause of memory impairment today. Various stress-based models are being developed for studying cognitive impairment. Repurposing of existing drugs in a new pharmacology class is the safest and cheapest option for treatment instead of new drug discovery.

Monocytes complexed to platelets differentiate into functionally deficient dendritic cells.

In addition to their role in hemostasis, platelets store numerous immunoregulatory molecules such as CD40L, TGFβ, β2-microglobulin, and IL-1β and release them upon activation. Previous studies indicate that activated platelets form transient complexes with monocytes, especially in HIV infected individuals and induce a proinflammatory monocyte phenotype. Because monocytes can act as precursors of dendritic cells (DCs) during infection/inflammation as well as for generation of DC-based vaccine therapies, we evaluated the impact of activated platelets on monocyte differentiation into DCs.

Inhibition of Tropomyosin Receptor Kinase A Signaling Negatively Regulates Megakaryopoiesis and induces Thrombopoiesis.

Neurotrophin signaling modulates the differentiation and function of mature blood cells. The expression of neurotrophin receptors and ligands by hematopoietic and stromal cells of the bone marrow indicates that neurotrophins have the potential to regulate hematopoietic cell fate decisions. This study investigates the role of neurotrophins and Tropomyosin receptor kinases (Trk) in the development of megakaryocytes (MKs) and their progeny cells, platelets.

Mild Cognitive Impairment in Young Type 1 Diabetes Mellitus Patients and Correlation with Diabetes Control, Lipid Profile, and High-sensitivity C-reactive Protein.

Background: It has been an established fact that diabetes mellitus (DM) is associated with lower levels of cognitive function and may be a risk factor for the development of mild cognitive impairment (MCI) and dementia. Most of these studies involved elderly diabetes patients and aging itself may contribute to cognitive impairment. Since a majority of the individuals with DM are between the ages of 40 and 59 years, it is crucial to determine the factors that contribute to cognitive impairment in these patients.

This phase II / III clinical trial was conducted to evaluate the immunogenicity and safety of the Tetravalent Influenza vaccine (Split virion) I.P. (TetIV) developed indigenously in the country for the first time by M/s Cadila Healthcare Limited, India containing two influenza A and two influenza B strains, one of each, Yamagata (B/Phuket) and Victoria (B/Brisbane) lineage and also compare it to that of an licensed seasonal Trivalent Influenza vaccine (TriIV) of Sanofi Pasteur India Private Limited, containing the two influenza A and only the Yamagata lineage (B/Phuket) strain.

Sonic Hedgehog mimetic prevents leukocyte infiltration into the CNS during acute HIV infection.

Infiltration of infected leukocytes culminates in establishment of a brain niche for Human Immunodeficiency Virus (HIV) during acute phase of infection, initiating an ongoing cascade of persistent viral replication and inflammation, that causes irreversible neuronal injury and HIV associated neurocognitive disease (HAND). In this study, humanized mice were treated with Smoothened Agonist (SAG), a Sonic Hedgehog (Shh) mimetic in order to fortify blood brain barrier (BBB) and dampen leukocyte extravasation into CNS during AHI. Results indicate that SAG treatment reduced viral burden in the CNS immediately after HIV transmission, but also conferred extended neuroprotection via increased BBB integrity (elevated levels of tight-junction protein, Claudin 5, and reduced S100B levels in periphery).

Blocked transcription through KvDMR1 results in absence of methylation and gene silencing resembling Beckwith-Wiedemann syndrome.

The maternally methylated KvDMR1 ICR regulates imprinted expression of a cluster of maternally expressed genes on human chromosome 11p15.5. Disruption of imprinting leads to Beckwith-Wiedemann syndrome (BWS), an overgrowth and cancer predisposition condition.

Preventive and therapeutic challenges in combating Zika virus infection: are we getting any closer?

The neuroteratogenic nature of Zika Virus (ZIKV) infection has converted what would have been a tropical disease into a global threat. Zika is transmitted vertically via infected placental cells especially in the first and second trimesters. In the developing central nervous system (CNS), ZIKV can infect and induce apoptosis of neural progenitor cells subsequently causing microcephaly as well as other neuronal complications in infants.
