Neurodegenerative disorders: Mechanisms of degeneration and therapeutic approaches with their clinical relevance.

Neurodegenerative disorders (NDs) are expected to pose a significant challenge for both medicine and public health in the upcoming years due to global demographic changes. NDs are mainly represented by degeneration/loss of neurons, which is primarily accountable for severe mental illness. This neuronal degeneration leads to many neuropsychiatric problems and permanent disability in an individual.

Potential biomaterials and experimental animal models for inventing new drug delivery approaches in the neurodegenerative disorder: Multiple sclerosis.

The tight junction of endothelial cells in the central nervous system (CNS) has an ideal characteristic, acting as a biological barrier that can securely regulate the movement of molecules in the brain. Tightly closed astrocyte cell junctions on blood capillaries are the blood-brain barrier (BBB). This biological barrier prohibits the entry of polar drugs, cells, and ions, which protect the brain from harmful toxins.

Comparative docking analysis of tyrosine kinase inhibitors with HER2 and HER4 receptors.

Tyrosine kinase receptors promote the growth and differentiation of normal breast and malignant human breast cancer cells, known as ERBB receptors. Various ERBB receptors are EGFR/ErbB1 and ErbB2/neu, which get over expressed in different solid tumors that activate upon binding of ligand to the extra cellular domain of these receptors. Of note, the epidermal growth factor receptor (EGFR) is a prime contributor to cancer through the involvement of four receptor tyrosine kinases (RTKs), namely, HER1, HER2, HER3, and HER4.

Hepatoprotective activity of Balsamodendron mukul extract against Paracetamol-induced liver toxicity in rats: In vivo pharmacological and toxicological evaluation.

Overuse of the antipyretic agent Paracetamol (PCM) is linked to hepatotoxicity, which limits its clinical use. The goal of this investigation was to find out how well Balsamodendron mukul (B. mukul) extract protects the liver from acute PCM poisoning.

Nose-to-brain delivery of octreotide acetate in situ gel for pituitary adenoma: Pharmacological and in vitro cytotoxicity studies.

Octreotide acetate (OA), a potent octapeptide, is used in the treatment of pituitary adenoma. An approach has been made in the present research to formulate an OA-loaded intranasal in situ gel (OA-ISG) to target pituitary adenoma. To achieve the objective of the present work, OA-ISG was fabricated using cold method, and further optimization was done by 3 factorial design.

Nose-to-brain delivery of paliperidone palmitate poloxamer-guar gum nanogel: Formulation, optimization and pharmacological studies in rats.

Oral delivery of paliperidone palmitate (PPD), a potent antipsychotic agent, has been reported with a potential risk of very serious drug-induced adverse events such as tachycardia, hyperprolactinemia, sexual dysfunction, and neutropenia. Alternatively, the potential of nasal delivery has also been explored to treat CNS complications by delivering the medicines directly to the brain bypassing the blood-brain barrier. Hence, the objectives of current work were to formulate, design, optimize, and investigate the therapeutic potency of PPD-loaded intranasal in-situ gel (PPGISG) in the treatment of schizophrenia.
