Chemical Profile and Potential Application of Agri-food Waste Products for Counteracting Diabetes Induced Neuropathy in Rats.

This study aimed to prepare defatted ethanol extract of Abelmoschus esculentus leaves, Morus nigra leaves and Punica granatum peel, to identify the chemical composition of these extracts and to explore their efficacy in counteracting diabetic neuropathy. LC-ESI-MS spectrometry was the hyphenated tool for component identification of these extracts. Behavioral, biochemical, and histopathological investigations were carried out after treatments of diabetic rats.

Molecular Mechanisms Underlying the Anti-Breast Cancer Stem Cell Activity of Pterocladia capillacea and Corallina officinalis Polysaccharides.

Objective: This study aimed to appraise the activity of Pterocladia capillacea and Corallina officinalis polysaccharides against Breast Cancer Stem Cells (BCSCs). P. capillacea and C.

Crosslink among phosphatidylinositol-3 kinase/Akt, PTEN and STAT-5A signaling pathways post liposomal galactomannan hepatocellular carcinoma therapy.

Liposomal drug-delivery systems (LDDs) provide a promising opportunity to precisely target organs, improve drug bioavailability and reduce systemic toxicity. On the other hand, PIK/Akt signaling pathways control various intracellular functions including apoptosis, invasion and cell growth. Hyper activation of PI3K and Akt is detected in some types of cancer that posses defect in PTEN.

Cubic liquid crystalline nanoparticles containing a polysaccharide with potent antihyperlipidaemic activity.

The present study involves the preparation of cubic liquid crystalline nanoparticles (cubsomes) for liver targeting to assess the potential of a formulated bioactive polysaccharide isolated from the hot aqueous extract of as an alternative natural agent with anti-hyperlipidaemic activity. Cubosomal nanoparticles were prepared by disrupting the cubic gel phase of the polysaccharide and water in the presence of a surfactant. Different lipid matrices and stabilizers were tested.

Regulation of apoptotic and inflammatory signaling pathways in hepatocellular carcinoma via Caesalpinia gilliesii galactomannan.

A polysaccharide characterized as galactomannan (GMann) with a molecular weight of 117.76 kDa was isolated from the aqueous extract of Caesalpinia gilliesii (C. gilliesii) seeds then assessed for antiproliferative potential against human hepatocellular carcinoma cell line (HepG2).

Exploiting bilosomes for delivering bioactive polysaccharide isolated from Enteromorpha intestinalis for hacking hepatocellular carcinoma.

Bile salts containing vesicles (bilosomes) represent a portentous vesicular carrier that showed prosperous results in delivering active moieties in the gastrointestinal tract (GIT). In this study, bilosomes were exploited to deliver sulfated polysaccharide-protein complexes of Enteromorpha intestinalis (EHEM) and enhance its activity against hepatocellular carcinoma as well as resist harsh GIT conditions. Bilosomes were prepared using the sodium salt of three different bile acids (cholic, deoxycholic, taurodeoxycholic) and two different nonionic surfactants (Span 40 and 65).

Therapeutic impact of grape leaves polyphenols on certain biochemical and neurological markers in AlCl-induced Alzheimer's disease.

Alzheimer's disease (AD) is a grave and prevailing neurodegenerative disease, characterized by slow and progressive neurodegeneration in different brain regions. Aluminum (Al) is a potent and widely distributed neurotoxic metal, implicated in the neuropathogenesis of AD. This study aimed to evaluate the possible neurorestorative potential of Vitis vinifera Leaves Polyphenolic (VLP) extract in alleviating aluminum chloride (AlCl)-induced neurotoxicity in male rats.

Influence of bioactive sulfated polysaccharide-protein complexes on hepatocarcinogenesis, angiogenesis and immunomodulatory activities.

Objective: To explore the in vivo anticancer, anti-angiogenesis and immunomodulatory efficacies of the bioactive polysaccharide isolated from cold aqueous extract of Jania rubens (JCEM) and Pterocladia capillacea (PCEM) as well as hot aqueous extract of Enteromorpha intestinalis (EHEM) against hepatocellular carcinoma rat model (HCC) and to study their chemical composition.

Methods: The sugars and amino acids composition of the bioactive polysaccharides of JCEM, PCEM and EHEM were determined using gas liquid chromatography and amino acid analyzer, respectively. These polysaccharide extracts (20 mg/kg b.

Assessment of anti-inflammatory, antinociceptive, immunomodulatory, and antioxidant activities of Cajanus cajan L. seeds cultivated in Egypt and its phytochemical composition.

Context: Cajanus cajan L. (Fabaceae), a food crop, is widely used in traditional medicine.

Objectives: The phytochemical composition of C.

Anti-HIV-1 and cytotoxicity of the alkaloids of Erythrina abyssinica Lam. growing in Sudan.

Erythrina abyssinica Lam. is an important medicinal plant growing in Sudan; its seeds were investigated for the first time for their alkaloidal constituents and biological activity. The in vitro cytotoxicity of the crude alkaloidal fraction (CAF) against the cell lines HeLa, Hep-G2, HEP-2, HCT116, MCF-7 and HFB4 showed promising activity, with IC₅₀ values of 13.

Cytotoxic xenicane diterpenes from the brown alga Padina pavonia (L.) Gaill.

Column chromatography of the hexane fraction of a methanol extract of Padina pavonia (L.) Gaill. collected from the Red Sea at Hurghada, Egypt yielded 18,19-epoxyxenic-19-methoxy-18-hydroxy-4-acetoxy-6,9,13-triene (1) and 18,19-epoxyxenic-18,19-dimethoxy-4-hydroxy-6,9,13-triene (2).
