Development of and evaluation of mucoadhesive in-situ gel for intranasal delivery of vinpocetine.

Alzheimer's disease (AD), which is marked by gradual neuronal decline and subsequent loss of cognitive functions and memory, poses significant treatment challenges. The present study involved the development, , and evaluation of a novel intranasal mucoadhesive in-situ gel of vinpocetine (VIN) with the aim to target the brain. An innovative gel formulation composed of poloxamer 407, HPMC E15 LV, and citric acid as a solubilizer was developed by 2 Factorial Design.

Biofabricated zinc oxide nanoparticles mitigate acrylamide-induced immune toxicity and modulate immune-related genes and microRNA in rats.

This study evaluated the potential efficacy of eco-friendly biofabricated zinc oxide nanoparticles (GS-ZnONP) (10 mg/kg b.wt) to reduce the impacts of long-term oral acrylamide (ALD) exposure (20 mg/kg b.wt) on the blood cells, immune components, splenic oxidative status, and expression of CD20, CD3, CD4, CD8, TNF-α, caspase-3, microRNA-181a-5p, and microRNA-125-5p in rats in a 60-day experiment.

The interplay of oxidative stress, apoptotic signaling, and impaired mitochondrial function in the pyrethroid-induced cardiac injury: Alleviative role of curcumin-loaded chitosan nanoparticle.

This study assessed the consequence of exposure to a pyrethroid insecticide, fenpropathrin (FPN), on the heart and the probable underlying mechanisms in rats. Moreover, the probable protective effect of curcumin-loaded chitosan nanoparticles (CMN-CNP) was evaluated. Forty male Sprague Dawley rats were distributed into four groups orally given corn oil, CMN-CNP (50 mg/kg b.

Chitosan/siRNA nanoparticles targeting PARP-1 attenuate Neuroinflammation and apoptosis in hyperglycemia-induced oxidative stress in Neuro2a cells.

Hyperglycemia induces an excessive production of superoxide by the mitochondria's electron-transport chain triggers several pathways of injury contributing to the development of diabetic complications. This increase in oxidative and nitrosative stress triggers the activation of PARP-1, a nuclear enzyme, through mechanisms such as DNA damage. siRNA-chitosan nanoparticles were formed based on electrostatic interaction, their particle size, zeta potential, STEM, and cellular uptake were characterized.

Role of Doxofylline, Low Dose Theophylline, and Dexamethasone in Mice (BALB/C) Model of Corticosteroid Resistant Asthma: A Comparative Study.

Objective: This study was designed to determine the comparative efficacy of Doxofylline (DOXO) compared to low-dose theophylline (LDT) in treating corticosteroid-resistant asthma.

Methods: This study was conducted on 56 adult BALB/C mice aged six to eight weeks old with an average weight of 20-25 g. They were divided into seven groups: control group, ovalbumin (OVA)+lipopolysaccharide (LPS) group, OVA+LPS+dexamethasone (DEXA) group, OVA+LPS+LDT group, OVA+LPS+ group, OVA+LPS+DEXA+LDT group, and OVA +LPS+DEXA+DOXO group.

Prevalence, demographic, socio-economic, and lifestyle factors associated with cigarette, e-cigarette, and dual use: evidence from the 2017-2021 Scottish Health Survey.

Understanding the correlation between demographic, socio-economic, and lifestyle factors with e-cigarette use, cigarette smoking, and dual use is essential for targeted public health interventions. This study examines the prevalence of these behaviors in Scotland and identifies the associated factors. We conducted a repeated cross-sectional analysis of the Scottish Health Survey data from 2017 to 2021, leveraging data from 12,644 participants aged 16 and older: 2271 cigarette smokers, 687 e-cigarette users, 428 dual users, and 9258 never users.

Challenges of therapeutic applications and regenerative capacities of urine based stem cells in oral, and maxillofacial reconstruction.

Urine-derived stem cells (USCs) have gained the attention of researchers in the biomedical field in the past few years . Regarding the several varieties of cells that have been used for this purpose, USCs have demonstrated mesenchymal stem cell-like properties, such as differentiation and immunomodulation. Furthermore, they could be differentiated into several lineages.

Detection of Adverse Drug Reactions in COVID-19 Hospitalized Patients in Saudi Arabia: A Retrospective Study by ADR Prompt Indicators.

Seeking an alternative approach for detecting adverse drug reactions (ADRs) in coronavirus patients (COVID-19) and enhancing drug safety, a retrospective study of six months was conducted utilizing an electronic medical record (EMR) database to detect ADRs in hospitalized patients for COVID-19, using "ADR prompt indicators" (APIs). Consequently, confirmed ADRs were subjected to multifaceted analyses, such as demographic attribution, relationship with specific drugs and implication for organs and systems of the body, incidence rate, type, severity, and preventability of ADR. The incidence rate of ADRs is 37%, the predisposition of organs and systems to ADR is observed remarkably in the hepatobiliary and gastrointestinal systems at 41.

Mental Health Issues Associated With COVID-19 Among the Elderly Population: A Narrative Review.

Since its discovery in December 2019, coronavirus disease 2019 (COVID-19) has been affecting humanity in economic, social, physical, and psychological manner. During COVID-19, the older population needs special consideration since they have a greater risk of developing serious illnesses. We used a narrative review approach to identify the relevant articles.
