Effects of almond consumption compared with the consumption of traditional isocaloric cereal/pulse-based snacks on glycaemic control and gut health in adults with pre-diabetes in rural India: protocol for a 16-week, parallel-arm, cluster randomised controlled trial.

Introduction: Almonds have prebiotic potential to maintain gut health and regulate glycaemia. Western studies have shown their positive effects on preventing non-communicable diseases like diabetes and cardiovascular diseases. However, there is a lack of research involving Asian Indians, who have a higher predisposition to diabetes due to their unique 'Asian phenotype'.

Early immune factors associated with the development of post-acute sequelae of SARS-CoV-2 infection in hospitalized and non-hospitalized individuals.

Background: Infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to post-acute sequelae of SARS-CoV-2 (PASC) that can persist for weeks to years following initial viral infection. Clinical manifestations of PASC are heterogeneous and often involve multiple organs. While many hypotheses have been made on the mechanisms of PASC and its associated symptoms, the acute biological drivers of PASC are still unknown.

The safety and efficacy of systemic delivery of a new liver-de-targeted TGFβ signaling inhibiting adenovirus in an immunocompetent triple negative mouse mammary tumor model.

Aberrant TGFβ signaling is linked to metastasis and tumor immune escape of many cancers including metastatic triple negative breast cancer (mTNBC). Previously, we have found that oncolytic adenoviruses expressing a TGFβ signaling inhibitory protein (sTGFβRIIFc) induced immune activation in a mouse TNBC (4T1) immunocompetent subcutaneous model with intratumoral injection. Systemic administration of adenoviruses can be a superior route to treat mTNBC but faces the challenges of increased toxicity and viral clearance.

Competitive inhibition of nicotine acetylcholine receptors using microneedles of nicotine and varenicline for smoking withdrawal therapy.

Current strategies for smoking withdrawal conditions involve monotherapy of nicotine and combinational therapy of nicotine with varenicline or bupropion as per the CDC and FDA. The available dosage forms for nicotine are patches, gums, inhalers and nasal sprays, bupropion and varenicline are available in tablet form. This research work focused on developing a microneedle delivery system to deliver combination drug for overcoming the obstacles encountered by oral route of administration of varenicline such as severe side effects (mood swings, agitation, depressed behaviour, seizures, etc), and nicotine therapy challenges such as short half-life, repeated dosing, nausea, and vomiting.

Bimatoprost-loaded lipidic nanoformulation development using quality by design: liposomes versus solid lipid nanoparticles in intraocular pressure reduction.

Bimatoprost is a drug used to lower intraocular pressure in the treatment of glaucoma. Conventional eye drops have the limitations of repeated dosing, drug loss due to tear outflow and hence poor availability for action. Using a systematic quality by design approach, liposomes and solid lipid nanoparticles were formulated and further encapsulated in thermo-sensitive hydrogel.

Distinct temporal trajectories and risk factors for Post-acute sequelae of SARS-CoV-2 infection.

Fragmented antibodies in non-small cell lung cancer: A novel nano-engineered delivery system for detection and treatment of cancer.

Non-small cell lung cancer (NSCLC) has a long history of defying traditional cytotoxic treatment. Significant advancements in biotechnology, cancer biology, and immunotherapy have provided new insights that have altered the landscape for the management of NSCLC, clearing the way for a new era of pharmaceuticals in the form of monoclonal antibodies and their fragments. Antibody fragments are superior to monoclonal antibodies because of their small size, which allows them to penetrate cells and tissues effectively.

Design and Characterization of Nanoflowers-based Biosensor for Estimation of Bilirubin in Jaundice.

Nanoflowers (NFs) are flower-shaped nanoparticulate systems with a higher surface-to-volume ratio and good surface adsorption. Jaundice indicates yellow discoloration of skin, sclera, and mucus membrane and is a clinical indication of bilirubin accumulation in the blood which occurs as a consequence of the incapability of the liver to excrete bilirubin in the biliary tree or conjugate bilirubin and higher production of bilirubin in the body. Several methods have been developed so far for bilirubin estimation in jaundice like the spectrophotometric method, chemiluminescence method, etc.

A systems biology investigation of curcumin potency against TGF-β-induced EMT signaling in lung cancer.

Unlabelled: Curcumin (diferuloylmethane) is bioactive phenolic compound which exerts diverse antimetastatic effect. Several studies have reported the antimetastatic effect of curcumin by its ability to modulate the epithelial-to-mesenchymal transition (EMT) process in different cancers, but underlying molecular mechanism is poorly understood. EMT is a highly conserved biological process in which epithelial cells acquire mesenchymal-like characteristics by losing their cell-cell junctions and polarity.
