Isolation and characterization of medicinal plant-based extracellular vesicles as nano delivery systems for ascorbic acid.

Aim: Plant-derived extracellular vesicles (EVs) are natural nanovesicles for drug delivery. This study isolated and characterised EVs from medicinal plants as delivery vehicles.

Methods: Precipitation method was employed for the isolation and characterised using DLS, SEM, and TEM.

Factors Associated with the Outcome of 2023 Diphtheria Outbreak in Jigawa State, Nigeria: A Retrospective Review of the Surveillance Data.

Objective: The objective of this study was to identify the factors associated with the outcome of the 2023 diphtheria outbreak in Jigawa State, Nigeria.

Methods: A descriptive cross-sectional study was conducted amongst all line-listed diphtheria cases reported from Jigawa State, Nigeria, using the 2023 Integrated Disease and Surveillance Response line list of cases that met the World Health Organization case definition of diphtheria. A total of 245 line-listed cases from January 2023 to December 2023 met the criteria for inclusion in the study.

Antioxidant-based neuroprotective effect of dimethylsulfoxide against induced traumatic brain injury in a rats model.

Traumatic brain injury (TBI) has been the result of neurological deficit and oxidative stress. This study evaluated the antioxidative neuroprotective property and learning and memory-enhancing effects of dimethyl sulfoxide (DMSO) in a rat model after the induction of TBI. 21 albino rats with 7 rats per group were used in this study.

Efficacy of stem cell secretome in the treatment of traumatic brain injury: A systematic review and meta-analysis of preclinical studies.

Traumatic brain injury (TBI) remains a public health challenge and represents one of the major contributors to disability and mortality worldwide among all trauma-related injuries. This study aimed to determine a precise effect size of secretome intervention in TBI. We performed a systematic literature search through Cochrane, MEDLINE Complete, PubMed and Scopus databases for articles published until June 2021.

A systematic review with meta-analysis on the antihypertensive efficacy of Nigerian medicinal plants.

Ethnopharmacological Relevance: Despite the promising effects of herbal preparations in lowering blood pressure (BP), hypertension remains a major clinical challenge in Nigeria. The BP-lowering effects of medicinal plants are due to the presence of bioactive compounds.

Aim Of The Study: This meta-analysis presents a precise estimate of the therapeutic benefits of medicinal plants utilized in Nigeria for the management of hypertension in animals and humans.

Effect of natron administration on the antioxidant status and lipid profile of rats.

Natron consumption has been implicated in the pathogenesis of peripartum cardiomyopathy. This work evaluates the effect of natron on the antioxidant status and lipid profile of postpartum rats administered graded doses of natron for four consecutive weeks. After treatment, the rats were assessed for antioxidant status, malondialdehyde level, and lipid profile.

Therapeutic efficacy of mesenchymal stromal cells and secretome in pulmonary arterial hypertension: A systematic review and meta-analysis.

Mesenchymal stromal cells (MSCs) and secretome are promising therapies for pulmonary arterial hypertension (PAH). This meta-analysis aimed to provide a precise estimate and compare the therapeutic efficacy of MSC and secretome in PAH. We searched six databases (CINAHL, Cochrane, Ovid Medline, PubMed, Science Direct and Scopus) until December 2018 using search terms related to MSCs, secretome and PAH.

Biochemical and histological changes in the heart of post-partum rats exposed to Natron.

Background: The customary puerperal practice of Natron consumption has been identified as one of the predisposing factors in the etiology of peripartum cardiomyopathy (PPCM). This study was designed to investigate the effect of Natron in postpartum Wistar albino rats.

Methods: A total of 30 postpartum Wistar rats were exposed to different doses (50mg/kg, 100mg/kg, 200mg/kg and 300mg/kg) of Natron for 28days.

In vitro screening for protein tyrosine phosphatase 1B and dipeptidyl peptidase IV inhibitors from selected Nigerian medicinal plants.

Background/aim: Protein tyrosine phosphatase 1B (PTP 1B) and dipeptidyl peptidase IV (DPP IV) have been identified as one of the drug targets for the treatment of Type-2 diabetes. This study was designed to screen for PTP 1B and DPP-IV inhibitors from some Nigerian medicinal plants.

Materials And Methods: PTP 1B and DPP-IV drug discovery kits from Enzo Life Sciences were used to investigate in vitro inhibitory effect of crude methanolic extract of 10 plants; , , , , , , , , , and .

Effects of α-tocopherol and ascorbic acid in the severity and management of traumatic brain injury in albino rats.

Background: Traumatic brain injury (TBI) is accompanied by substantial accumulation of biomarkers of oxidative stress and depletion of antioxidants reserve which initiate chain reactions that damage brain cells. The present study investigated the role of ascorbic acid and α-tocopherol on the severity and management of TBI in rats.

Materials And Methods: Wistar rats were subjected to closed head injury using an accelerated impact device.

Serum levels of antioxidant vitamins and mineral elements of human immunodeficiency virus positive subjects in Sokoto, Nigeria.

Background: Undernourishment and micronutrient deficiencies exacerbate immunosuppression, oxidative stress, acceleration of human immunodeficiency virus (HIV) replication and CD4 T-cell depletion in HIV-infected individuals.

Materials And Methods: The current work reports the serum levels of antioxidant vitamins (vitamins A, C and E) and minerals (Zn, Fe, Cu) in 90 HIV positive subjects attending the Usmanu Danfodiyo University Teaching Hospital (UDUTH), Sokoto, Nigeria. The serum levels of the micronutrients were correlated with the CD4 count of the subjects.
