Validating the nutraceutical and neuroprotective pharmacodynamics of flavones.

Neurodegenerative disorders are generally characterized by progressive neuronal loss and cognitive decline, with underlying mechanisms involving oxidative stress, protein aggregation, neuroinflammation, and synaptic dysfunction. Currently, the available treatment options only improve the symptoms of the disease but do not stop disease progression; neurodegeneration. This underscores the urgent need for novel therapeutic strategies targeting multiple neurodegenerative pathways alongside the conventional therapeutic strategies available.

Assessing effects of Cannabis on various neuropathologies: A systematic review.

Natural bioactives possess a wide range of chemical structures that can exert a plethora of pharmacological and toxicological actions, resulting in neuroprotection or neurotoxicity. These pharmacodynamic properties can positively or negatively impact human and animal global healthcare. Remarkably, Ayurvedic botanical Cannabis has been used worldwide by different ethnicities and religions for spiritual, commercial, recreational, nutraceutical, cosmeceutical, and medicinal purposes for centuries.

Production of tannase from a newly isolated yeast, using agro-residues.

With an aim of producing commercially important tannase enzyme using cheap and readily available agro-residues, leaves of Indian Gooseberry () and Jamun (), peels of Lemon (), and Pomegranate () were screened. Newly isolated was utilized for the study. Preliminary studies indicated that tannase titer obtained is not proportional to the tannin content of the agro-residues and solid state fermentation superior compared to submerged fermentation.

A total of 22 AS patients were analyzed and compared against 10 healthy subjects.

Chandamarutha Chenduram, an Indian traditional Siddha preparation attenuated the neuronal degeneration in ischemic mice through ameliorating cytokines and oxy-radicals mediated EAAT-2 dysfunction.

Ethnopharmacological Relevance: Chandamarutha Chenduram (CC), an Indian traditional Siddha preparation officially recorded in the Siddha formulary of India and its composition are widely used in the Siddha practice of neurological disorders like stroke/paralysis in India. However, the scientific validation and mechanistic evidence is lacking and yet to be elucidated.

Aim Of The Study: To establish the scientific evidences and to explore the possible neuroprotective mechanism of CC in cerebral ischemia.

Hypoxia stimulates angiogenesis and a metabolic switch in human parathyroid adenoma cells.

Hypoxia, a primary stimulus for angiogenesis, is important for tumour proliferation and survival. The effects of hypoxia on parathyroid tumour cells, which may also be important for parathyroid autotransplantation in patients, are, however, unknown. We, therefore, assessed the effects of hypoxia on gene expression in parathyroid adenoma (PA) cells from patients with primary hyperparathyroidism.

Cumin Prevents 17β-Estradiol-Associated Breast Cancer in ACI Rats.

Breast cancer (BC) is a leading cause of cancer deaths in women in less developed countries and the second leading cause of cancer death in women in the U.S. In this study, we report the inhibition of E2-mediated mammary tumorigenesis by (cumin) administered via the diet as cumin powder, as well as dried ethanolic extract.

Minutes of PPAR-γ agonism and neuroprotection.

Peroxisome proliferator-activated receptor gamma (PPAR-γ) is one of the ligand-activated transcription factors which regulates a number of central events and considered as a promising target for various neurodegenerative disease conditions. Numerous reports implicate that PPAR-γ agonists have shown neuroprotective effects by regulating genes transcription associated with the pathogenesis of neurodegeneration. In regards, this review critically appraises the recent knowledge of PPAR-γ receptors in neuroprotection in order to hypothesize potential neuroprotective mechanism of PPAR-γ agonism in chronic neurological conditions.

Chemoprevention of Colorectal Cancer by Anthocyanidins and Mitigation of Metabolic Shifts Induced by Dysbiosis of the Gut Microbiome.

Diets rich in fat, smoking, as well as exposure to environmental pollutants and dysbiosis of gut microbiota, increase the risk of developing colorectal cancer. Much progress has been made in combating colorectal cancer. However, options for chemoprevention from environmental insult and dysbiosis of gut microbiota remain elusive.

Mice with a Brd4 Mutation Represent a New Model of Nephrocalcinosis.

Nephrolithiasis (NL) and nephrocalcinosis (NC), which comprise renal calcification of the collecting system and parenchyma, respectively, have a multifactorial etiology with environmental and genetic determinants and affect ∼10% of adults by age 70 years. Studies of families with hereditary NL and NC have identified >30 causative genes that have increased our understanding of extracellular calcium homeostasis and renal tubular transport of calcium. However, these account for <20% of the likely genes that are involved, and to identify novel genes for renal calcification disorders, we investigated 1745 12-month-old progeny from a male mouse that had been treated with the chemical mutagen N-ethyl-N-nitrosourea (ENU) for radiological renal opacities.

Milk exosomes - Natural nanoparticles for siRNA delivery.

Gene-silencing with targeted siRNAs has great potential as a therapeutic approach for various diseases including cancer. However, intracellular delivery of siRNA is challenging. We used bovine milk exosomes as a novel system for siRNA delivery.

An N-Ethyl-N-Nitrosourea (ENU)-Induced Tyr265Stop Mutation of the DNA Polymerase Accessory Subunit Gamma 2 (Polg2) Is Associated With Renal Calcification in Mice.

Renal calcification (RCALC) resulting in nephrolithiasis and nephrocalcinosis, which affects ∼10% of adults by 70 years of age, involves environmental and genetic etiologies. Thus, nephrolithiasis and nephrocalcinosis occurs as an inherited disorder in ∼65% of patients, and may be associated with endocrine and metabolic disorders including: primary hyperparathyroidism, hypercalciuria, renal tubular acidosis, cystinuria, and hyperoxaluria. Investigations of families with nephrolithiasis and nephrocalcinosis have identified some causative genes, but further progress is limited as large families are unavailable for genetic studies.

Development of a goat model for evaluation of withaferin A: Cervical implants for the treatment of cervical intraepithelial neoplasia.

Cervical cancer is caused by human papillomavirus (HPV). The disease develops over many years through a series of precancerous lesions. Cervical cancer can be prevented by HPV-vaccination, screening and treatment of precancer before development of cervical cancer.

Exosomes for the Enhanced Tissue Bioavailability and Efficacy of Curcumin.

Exosomes are extracellular microvesicles with a particle size of 30-100 nm and carry a cargo of proteins, lipids, RNA, and DNA. Their properties of shuttling in-and-out of the cells suggest that these particles can be exploited as a nano drug carrier. In this manuscript, we show that curcumin can be delivered effectively using milk-derived exosomes.

Exosomal delivery of berry anthocyanidins for the management of ovarian cancer.

Despite optimal diagnosis and early therapeutic interventions, the prognosis for ovarian cancer patients remains dismal because the efficacy of chemotherapy is limited by the development of resistance and off-site toxicity. Berry bioactives indicate preventive and therapeutic activities against various cancer types. Here, we examined the antiproliferative activity of berry anthocyanidins (Anthos) against drug-sensitive (A2780) and drug-resistant (A2780/CP70, OVCA432 and OVCA433) ovarian cancer cells.

Milk-derived exosomes for oral delivery of paclitaxel.

In this report milk-derived exosomes have been investigated for oral delivery of the chemotherapeutic drug paclitaxel (PAC) as an alternative to conventional i.v. therapy for improved efficacy and reduced toxicity.

Mice deleted for cell division cycle 73 gene develop parathyroid and uterine tumours: model for the hyperparathyroidism-jaw tumour syndrome.

The hyperparathyroidism-jaw tumour (HPT-JT) syndrome is an autosomal dominant disorder characterized by occurrence of parathyroid tumours, often atypical adenomas and carcinomas, ossifying jaw fibromas, renal tumours and uterine benign and malignant neoplasms. HPT-JT is caused by mutations of the cell division cycle 73 (CDC73) gene, located on chromosome 1q31.2 and encodes a 531 amino acid protein, parafibromin.
