Neem seed oil ameliorates diabetic phenotype by suppressing redox imbalance, dyslipidaemia and pro-inflammatory mediators in a rodent model of type 2 diabetes.

The neem plant () has popular ethnomedicinal applications. The anti-diabetic potential and mechanism of neem seed oil (NSO) in a rodent model of type 2 diabetes mellitus was evaluated in the present study. Experimentally-induced diabetic animals were administered NSO (200 and 400 mg/kg) or metformin (150 mg/kg) orally for 30 days, with some animals serving as positive and negative controls.

CXC Chemokines in the Pathogenesis of Pulmonary Disease and Pharmacological Relevance.

Chemokines and their receptors play important roles in the pathophysiology of many diseases by regulating the cellular migration of major inflammatory and immune players. The CXC motif chemokine subfamily is the second largest family, and it is further subdivided into ELR motif CXC (ELR+) and non-ELR motif (ELR-) CXC chemokines, which are effective chemoattractants for neutrophils and lymphocytes/monocytes, respectively. These chemokines and their receptors are expected to have a significant impact on a wide range of lung diseases, many of which have inflammatory or immunological underpinnings.

Coronavirus Disease 2019 and Herbal Therapy: Pertinent Issues Relating to Toxicity and Standardization of Phytopharmaceuticals.

Unlabelled: Coronavirus disease 2019 (COVID-19) is a virulent viral disease that has now become a public health emergency of global significance and still without an approved treatment regimen or cure. In the absence of curative drugs and with vaccines development still in progress, alternative approaches to stem the tide of the pandemic are being considered. The potential of a phytotherapeutic approach in the management of the dreaded disease has gained attention, especially in developing countries, with several claims of the development of anti-COVID-19 herbal formulations.

Nutritional benefits, phytochemical constituents, ethnomedicinal uses and biological properties of Miracle fruit plant ( Shumach. & Thonn. Daniell).

Miracle fruit plant or Miracle berry plant () is a peculiar medicinal plant because of the unique taste-modifying property of its fruit which is due to the presence of the glycoprotein, miraculin. This property has been known for centuries to the people of tropical Western and Central Africa who also employ different parts of the plant in the management of various ailments. Scientific investigations have unravelled several pharmacological properties of the plant which include antidiabetic, blood cholesterol-lowering, anti-hyperuricaemia, antioxidant, anticonvulsant and anticancer properties.

Prevalence of COVID-19 Diagnostic Output with Chest Computed Tomography: A Systematic Review and Meta-Analysis.

Background: The pooled prevalence of chest computed tomography (CT) abnormalities and other detailed analysis related to patients' biodata like gender and different age groups have not been previously described for patients with coronavirus disease 2019 (COVID-19), thus necessitating this study. Objectives To perform a meta-analysis to evaluate the diagnostic performance of chest CT, common CT morphological abnormalities, disease prevalence, biodata information, and gender prevalence of patients.

Methods: Studies were identified by searching PubMed and Science Direct libraries from 1 January 2020 to 30 April 2020.

Angiotensin-1-converting enzyme inhibition, antioxidant activity, and modulation of cerebral Na+/K+ ATPase by free phenolics of African locust bean (Parkia biglobosa).

Aims: To investigate the antioxidant activities and effects of free phenols (FPPB) and bound phenols (BPPB) of Parkia biglobosa leaves on some enzymes of neuro-cardiovascular relevance.

Methods And Results: HPLC-DAD fingerprinting of FPPB and BPPB, and the antihemolytic, radical (1,1-diphenyl-2 picrylhydrazyl, DPPH; 2,2-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid), ABTS) scavenging and ferric reducing antioxidant properties of extracts, were assessed. In addition, the effects of the phenolics on angiotensin-1-converting enzyme (ACE), cerebral acetylcholinesterase/butyrylcholinesterase (AChE/BuChE), and Na/KATPase were determined in vitro.

Antioxidant activity and protective effects of cocoa and kola nut mistletoe (Globimetula cupulata) against ischemia/reperfusion injury in Langendorff-perfused rat hearts.

Protection against cardiomyocyte damage following ischemia/reperfusion (I/R) injury is highly desirable in patients with ischemic heart disease. Hydromethanol extracts of Globimetula cupulata (mistletoe) growing on cocoa (CGCE) and kola nut (KGCE) trees were assessed for antioxidant content and cardioprotective potential against I/R. Graded concentrations (1-50 μg/mL) of CGCE or KGCE were tested on Langendorff-perfused rat hearts to evaluate the effects on the flow rate, heart rate, and force of cardiac contraction, while another set of hearts were subjected to biochemical analyses.

Effect of homopterocarpin, an isoflavonoid from Pterocarpus erinaceus, on indices of liver injury and oxidative stress in acetaminophen-provoked hepatotoxicity.

Background: Novel hepatoprotectives are needed to address the increasing cases of liver problems worldwide. Pterocarpus erinaceus Poir (Fabaceae) ethanol stem bark extract (PE) and its constituent flavonoid, homopterocarpin (HP), were investigated for their protective property in acetaminophen-induced oxidative stress and liver damage.

Methods: Adult male albino rats were divided into nine groups.

Protective effects of Parinari curatellifolia flavonoids against acetaminophen-induced hepatic necrosis in rats.

In the present study, we investigated the hepatoprotective potential of Parinari curatellifolia Planch (Chrysobalanaceae) in experimental rats in order to ascertain the validity of folkloric claims of its effectiveness in the treatment of hepatic-related disorders. Flavonoid extract of P. curatellifolia seed, PCF (10-, 20- or 30 mg/kg body weight) or silymarin (25 mg/kg), dissolved in corn oil, was administered by gavage to experimental animals once daily for 14 consecutive days before liver damage was chemically induced through the administration of acetaminophen (2 g/kg p.

Parkia biglobosa improves mitochondrial functioning and protects against neurotoxic agents in rat brain hippocampal slices.

Objective: Methanolic leaf extracts of Parkia biglobosa, PBE, and one of its major polyphenolic constituents, catechin, were investigated for their protective effects against neurotoxicity induced by different agents on rat brain hippocampal slices and isolated mitochondria.

Methods: Hippocampal slices were preincubated with PBE (25, 50, 100, or 200 µg/mL) or catechin (1, 5, or 10 µg/mL) for 30 min followed by further incubation with 300 µM H2O2, 300 µM SNP, or 200 µM PbCl2 for 1 h. Effects of PBE and catechin on SNP- or CaCl2-induced brain mitochondrial ROS formation and mitochondrial membrane potential (ΔΨm) were also determined.

In vitro antioxidant activity and effect of Parkia biglobosa bark extract on mitochondrial redox status.

Aqueous-methanolic extract of Parkia biglobosa bark (PBB) was screened for its polyphenolic constituents, in vitro antioxidant activity, and effect on mitochondria redox status. The in vitro antioxidant activity was assessed by using the scavenging abilities and the reducing powers of 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) diammonium salt radical cation against Fe(3+). Subsequently, the ability of PBB to inhibit lipid peroxidation induced by FeSO(4) (10 μm) and its metal-chelating potential were investigated.
