Dendrimers: Advancing Therapeutic Strategies for Dementia.

Dementia, characterized by a progressive decline in cognitive function, poses a significant challenge to global healthcare systems, with current therapeutic approaches offering limited efficacy. The development of nanotechnology-based drug delivery systems has introduced promising avenues for enhancing the treatment of neurodegenerative disorders such as Alzheimer's disease. Dendrimers, with their highly branched, nanoscale structure, provide an innovative platform for targeted drug delivery to the brain.

Mitochondrial Dysfunction in Cardiac Diseases: Insights into Pathophysiology and Clinical Outcomes.

Mitochondrial dysfunction plays a crucial role in the pathogenesis of various cardiac diseases, including heart failure, ischemic cardiomyopathy, and drug-induced cardiotoxicity. Mitochondria are essential for cellular energy production, calcium homeostasis, redox balance, and apoptotic regulation, making their proper function vital for cardiac health. Dysfunctional mitochondria contribute to excessive reactive oxygen species (ROS) production, impaired ATP synthesis, and disruption of mitochondrial dynamics, leading to cardiomyocyte damage and cell death.

Modulation of Angiotensin-II and Angiotensin 1-7 Levels Influences Cardiac Function in Myocardial Ischemia-reperfusion Injury.

The angiotensin-converting enzyme-2 (ACE-2) alters the pathophysiology of various fatal cardiovascular diseases, including ischemic heart disease, whereas angiotensin 1-7 (Ang 1-7) exerts a wide range of actions. The effects of ischemia-reperfusion (IR) injury include damage to myocardial tissue that initiates protease action, causing cardiac cell death. Angiotensin- II (Ang-II) contributes through the renin-angiotensin system (RAS) to the IR injury, whereas Ang 1-7 paradoxically exerts a protective effect through the same.

Role of Vitamin D in Management of Diabetes and Unresolved Cardiovascular Diseases.

Background: Vitamin D deficiency is becoming a widely recognized global health issue. Serum values of 25-(OH) vitamin D (<20 ng/ml) are used to identify vitamin D deficiency. By prompting vascular endothelial cells to activate their nuclear receptor in cardio-myocytes, Vitamin D regulates obesity, Renin-angiotensin system (RAS), energy consumption, and pancreatic cell function.

Consequence of Dementia and Cognitive Impairment by Primary Nucleation Pathway.

An acquired loss of cognition in several cognitive domains that is severe enough to interfere with social or professional functioning is called dementia. As well as a moderately in-depth mental status examination by a clinician to identify impairments in memory, language, attention, visuospatial cognition, such as spatial orientation, executive function, and mood, the diagnosis of dementia requires a history evaluating for cognitive decline and impairment in daily activities, with confirmation from a close friend or family member. The start and organization of the cognitive assessment can be helped by short screening tests for cognitive impairment.

Repurposing of Drugs for Cardiometabolic Disorders: An Out and Out Cumulation.

Cardiometabolic disorders (CMD) is a constellation of metabolic predisposing factors for atherosclerosis such as insulin resistance (IR) or diabetes mellitus (DM), systemic hypertension, central obesity, and dyslipidemia. Cardiometabolic diseases (CMDs) continue to be the leading cause of mortality in both developed and developing nations, accounting for over 32% of all fatalities globally each year. Furthermore, dyslipidemia, angina, arrhythmia, heart failure, myocardial infarction (MI), and diabetes mellitus are the major causes of death, accounting for an estimated 19 million deaths in 2012.

Pleiotropic Benefits of Statins in Cardiovascular Diseases.

In 1976, Japanese microbiologist Akira Endo discovered the first statin as a product of the fungus that inhibited the activity of 3-hydroxy-3-methylglutaryl coenzyme A reductase. Their primary mode of action is to lower the blood cholesterol by decreasing hepatic cholesterol production, which upregulates hepatic low-density lipoprotein (LDL) receptors and increases LDL-cholesterol clearance. In addition to cholesterol lowering, statins inhibit other downstream products of the mevalonate pathway, causing the so-called pleiotropic effects.

An inquest into regulatory mechanism of caveolin by ischemic preconditioning against orchidectomy-challenged rat heart.

Lower level of testosterone in men is related to major risks of cardiovascular diseases. This risk may increase due to the opening of mitochondrial permeability transition pore (mPTP). The mPTP is also regulated by ischemic preconditioning (IPC) and a membrane protein known as caveolin.

Caveolins; An Assailant or An Ally of Various Cellular Disorders.

Caveolae have impressive morphological highlights of the cytomembrane of mammalian cells which involve in wide diversity of cellular functions involving signaling pathways and cholesterol hastening. Caveolin proteins possess a 'scaffolding' domain which for caveolin-1 and caveolin-3 appear to act a dominant role in signal regulation through caveolae. Caveolin-1 is treated to be protein in the cytomembrane entrapped with caveolae in endothelial cells and vascular smooth muscle cells which diminish nitric oxide (NO) by fill up the calcium/calmodulin (Ca/CaM) confining point of endothelial nitric oxide synthase (eNOS), decrease NO generation produce endothelial dysfunction and atherosclerotic injury development.

Cyanosomes: A pilot study.

Cyanobacteria are the most primitive, oxygen-evolving prokaryotic organism. Several, conspicuous investigations have been done around lipids from cyanobacteria. However, to date and to the best of our knowledge, no study was conducted to formulate and evaluate liposomal vesicles prepared from cyanobacterial lipid.

Mechanistic Pathways of ATP Sensitive Potassium Channels Referring to Cardio-Protective Effects and Cellular Functions.

A study of potassium channels correlates the fundamentals of mechanistic pathways and various physiological functions. The knowledge of these pathways provides the background, how to determine unit cell functions and to affect cardio protection. ATP sensitive potassium channels adjust excitability of membrane and functions as per metabolic status of cell.

An Insight on Silk Protein Sericin: From Processing to Biomedical Application.

Silks are naturally occurring polymers that have been used clinically as sutures for hundreds of years. It's so for obtained from insects or worms, silk consists of a filament core protein, termed fibroin, and a glue-like coating made up of sericin proteins. An important component of silk has an extended history of being discarded as a waste in the course of silk processing.

Bromelain capped gold nanoparticles as the novel drug delivery carriers to aggrandize effect of the antibiotic levofloxacin.

To develop bromelain capped gold nanoparticles (BRN capped Au-NPs) as the effective drug delivery carriers of the antibiotic levofloxacin (LvN) and evaluate antibacterial potential of its bioconjugated form compared to pure LvN. BRN capped Au-NPs were synthesized by method and bioconjugated to LvN using 1-ethyl-3-(3-dimethylamino-propyl)-carbodiimide as activator to form Au-BRN-LvN-NPs. These were characterized for mean particle size by dynamic light scattering analysis, zeta potential by Zetasizer nanosystem analysis and transmission electron microscopy (TEM) on carbon coated TEM copper grids by TEM respectively.
