Oral ingestion of Shiikuwasha extract suppresses diabetes progression in mice by preserving β-cell mass.

Introduction: Nobiletin is a polymethoxyflavonoid abundant in citrus peels and has been reported to have various bioactive effects. We have previously reported that nobiletin inhibits endoplasmic reticulum stress-induced apoptosis in the pancreatic β-cell line INS-1 and that continuous subcutaneous administration of nobiletin suppresses the progression of diabetes by protecting β-cells in type 2 diabetic mice. In the present study, we investigated effects of oral ingestion of Shiikuwasha extract rich in nobiletin on the pathogenesis of type 2 diabetes in mice.

Nanoparticle-based delivery systems as emerging therapy in retinoblastoma: recent advances, challenges and prospects.

Retinoblastoma is the most common intraocular malignancy in children. The treatment of this rare disease is still challenging in developing countries due to delayed diagnosis. The current therapies comprise mainly surgery, radiotherapy and chemotherapy.

Apigenin Alleviates Endoplasmic Reticulum Stress-Mediated Apoptosis in INS-1 β-Cells.

The improvement of type 2 diabetes mellitus induced by naturally occurring polyphenols, known as flavonoids, has received considerable attention. However, there is a dearth of information regarding the effect of the trihydroxyflavone apigenin on pancreatic β-cell function. In the present study, the anti-diabetic effect of apigenin on pancreatic β-cell insulin secretion, apoptosis, and the mechanism underlying its anti-diabetic effects, were investigated in the INS-ID β-cell line.

Bioactive compounds by microalgae and potentials for the management of some human disease conditions.

Microalgae biomasses are excellent sources of diverse bioactive compounds such as lipids, polysaccharides, carotenoids, vitamins, phenolics and phycobiliproteins. Large-scale production of these bioactive substances would require microalgae cultivation either in open-culture systems or closed-culture systems. Some of these bioactive compounds (such as polysaccharides, phycobiliproteins and lipids) are produced during their active growth phase.

Nanotechnology based drug delivery systems for the treatment of anterior segment eye diseases.

Diseases affecting the anterior segment of the eye are the primary causes of vision impairment and blindness globally. Drug administration through the topical ocular route is widely accepted because of its user/patient friendliness - ease of administration and convenience. However, it remains a significant challenge to efficiently deliver drugs to the eye through this route because of various structural and physiological constraints that restrict the distribution of therapeutic molecules into the ocular tissues.

Interleukin-18 cytokine in immunity, inflammation, and autoimmunity: Biological role in induction, regulation, and treatment.

Interleukin-18 (IL-18) is a potent pro-inflammatory cytokine involved in host defense against infections and regulates the innate and acquired immune response. IL-18 is produced by both hematopoietic and non-hematopoietic cells, including monocytes, macrophages, keratinocytes and mesenchymal cell. IL-18 could potentially induce inflammatory and cytotoxic immune cell activities leading to autoimmunity.

Evaluation of anti-malarial potency of new pyrazole-hydrazine coupled to Schiff base derivatives.

Background: The search for pharmacologically effective agents among molecules bearing multiple functionalities is commonly practiced. In continuation of the search for new anti-malarial agents, new pyrazole-hydrazine coupled Schiff-base derivatives previously synthesized were screened for anti-malarial property.

Methods: Here, in vivo prophylactic and curative activities of the compounds were assessed while their binding affinity for falcipain-2, a crucial enzyme in Plasmodium survival, was done using computational techniques.

Alzheimer's Disease: Pathogenesis and Therapeutic Interventions.

Background: Alzheimer's Disease (AD) is the most common cause of dementia. Genetics, excessive exposure to environmental pollutants, as well as unhealthy lifestyle practices are often linked to the development of AD. No therapeutic approach has achieved complete success in treating AD; however, early detection and management with appropriate drugs are key to improving prognosis.

Influence of Nigerian Jelly Ear Culinary-Medicinal Mushroom, Auricularia auricula-judae (Agaricomycetes), on Humoral and Cellular Immunity.

The fruiting body of Auricularia auricula-judae has received attention in folk medicine due to its possible medicinal values. Therefore, this study evaluated the immunomodulatory effects of the hot aqueous extract (AAAJ) and the β-D-glucan-rich polysaccharide fraction of A. auricula-judae (BGPA) on specific and nonspecific humoral and cell mediated immune responses in immunocompetent and immunosuppressed mice.

Immunomodulatory and immunorestorative activities of β-D-glucan-rich extract and polysaccharide fraction of mushroom, Pleurutus tuberregium.

Context: Some edible mushrooms are reputed to possess useful medicinal properties which are related to their ability to modulate the protective responses of the immune system.

Objective: This study explored the immunomodulatory and immunorestorative properties of a hot aqueous extract (APTR) and of a β-d-glucan-enriched polysaccharide fraction (BGP) of a local oyster mushroom Pleurutus tuberregium (Fr.) Singer (Pleurotaceae).

Hepato- and nephroprotective activities of a Nigerian local king tuber oyster mushroom, Pleurotus tuberregium (higher Basidiomycetes), in chemically induced organ toxicities in rats.

Chronic kidney disease, end-stage renal failure, and liver diseases are increasing worldwide and constitute a huge burden on health care costs, with attendant high morbidity and debility. Despite advances in modern medicine, there are still no licensed drugs that satisfactorily restore lost kidney or hepatic functions. In this study the chemoprotective effects of the hot aqueous extract of a local edible oyster mushroom, Pleurotus tuberregium (APTR), was evaluated in experimental liver and kidney toxicities.
