Curcumin, a compound belonging to the group of polyphenols with a characteristic yellow-orange color, is the most active ingredient of the long-leaved Curcuma longa L. and the ingredient of seasoning mixes, including curry spices. Due to its antioxidant, anti-inflammatory and anti-cancer properties, it has a wide range of therapeutic effects and has been studied for many years. Curcumin has enormous potential in preventing many diseases due to the widely described benefits of its use, it is non-toxic and additionally. Therapy with curcumin is low cost. Currently, many studies focus on the anti-glycation activity of curcumin, which could be used as an active inhibitor of glycation, i.e. a non-enzymatic process of combining a keto or aldehyde group of sugar with a free amino group of a protein. Finally, heterogeneous end products of advanced glycation are formed in the multistage and complicated glycation reaction. Formation of glycation products is intensified with age, as well as in various disease states, including diabetes or neurodegenerative diseases. Many literature data describe the role of curcumin in the prevention and treatment of diabetes. It is known that polyphenol has beneficial effects on hyperglycemia, insulin resistance and regeneration of secretory cells of pancreatic islets. It seems that addition of curcumin, the main ingredient of curry spice, to food could help people prevent the development of lifestyle diseases, including diabetes and its complications. The article presents the current state of knowledge on the curcumin anti-glycation properties in vitro as well as in vivo.

Neurodegenerative disorders have emerged as a serious health issue in the current era. The most common neurodegenerative disorders are Alzheimer’s disease (AD), Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis (ALS). These diseases involve progressive impairment of neurodegeneration and memory impairment. A wide range of compounds have been identified as potential neuroprotective agents against different models of neurodegeneration both in vivo and in vitro. Hesperetin, a flavanone class of citrus flavonoid, is a derivative of hesperidin found in citrus fruits such as oranges, grapes, and lemons. It has been extensively reported that hesperetin exerts neuroprotective effects in experimental models of neurodegenerative diseases. In this systematic review, we have compiled all the studies conducted on hesperetin in both in vivo and in vitro models of neurodegeneration. Here, we have used an approach to lessen the bias in each study, providing a least biased, broad understanding of findings and impartial conclusions of the strength of evidence and the reliability of findings. In this review, we collected different papers from a wide range of journals describing the beneficial effects of hesperetin on animal models of neurodegeneration. Our results demonstrated consistent neuroprotective effects of hesperetin against different models of neurodegeneration. In addition, we have summarized its underlying mechanisms. This study provides the foundations for future studies and recommendations of further mechanistic approaches to conduct preclinical studies on hesperetin in different models.

As the major cause of female anovulatory infertility, polycystic ovary syndrome (PCOS) affects a great proportion of women at childbearing age. Although glucagon-like peptide 1 receptor agonists (GLP-IRAs) show therapeutic effects for PCOS, its target and underlying mechanism remains elusive. In the present study, we identified that, both in vivo and in vitro, GLP-1 functioned as the regulator of proliferation and antiapoptosis of MGCs of follicle in PCOS mouse ovary. Furthermore, forkhead box protein O1 (FoxO1) plays an important role in the courses. Regarding the importance of granulosa cells (GCs) in oocyte development and function, the results from the current study could provide a more detailed illustration on the already known beneficial effects of GLP-1RAs on PCOS and support the future efforts to develop more efficient GLP-1RAs for PCOS treatment.

Resveratrol (RES) is a naturally occurring triphenolic phytoalexin compound exerting numerous beneficial effects in the organism. It has a wide range of biological activities in vitro as well as in vivo, such as anti-cancer, antioxidant, anti-inflammatory and beneficial cardiovascular effects. But, its low solubility in water led to its poor absorption in vivo and low bioavailability. Bovine serum album (BSA) nanoparticles have emerged as versatile desired carrier systems due to its ready availability, biodegradability, lack of toxicity and immunogenicity with fast development of nano technology. In this study, RES-BSANPS were prepared by a desolvation method and chemical cross-linking with glutaraldehyde successfully. Results controlled conditions (concentration of BSA, 10 mg/ml; pH = 9.0; volume of ethanol, 6 ml; volume of 0.25 % glutaraldehyde, 100 µl; amount of RES, 6.7 mg; cross-linking time, 24 h at room temperature (1 ml/min)) for entrapment efficiency, loading efficiency, mean particle size and zeta potential, were found to be 88.7 %, 39.4 %, 175.4 ± 0.5 nm, -35.93 ± 0.79 mV, respectively.

Clinical Potential

Exosomes are extracellular vesicles (EVs) belonging to the nanovesicles family that function as signaling molecules between cells. After their first description in the late 1960s, interest in their potential as a research target has steadily increased. They are small secreted organelles with a single membrane that are well enriched in lipids, proteins, nucleic acids, and glycoconjugates. Exosomes take part in a larger communication network in which cells communicate between one another by DNA shuttling, proteins, RNA, and membrane-bound factors. The machinery of protein quality control occurs through the process termed “exosome biogenesis”. Furthermore, the pathway involved in intercellular movement of vesicles is vital in various aspects of human health and diseases. Due to their inherent properties, exosomes are currently being developed as potential therapeutic agents in a wide range of diseases including infectious and non-infectious diseases. Exosomes and other EVs sourced from Mesenchymal stem cells (MSCs) have been shown in different studies to possess therapeutic effects in diverse disease models either in vivo or in vitro. Some mechanisms and/or pathways that MSC-derived exosomes use to illustrate their therapeutic effect against some diseases have also been summarized. This review aims to highlight the recent findings and potential therapeutic application of exosomes in different diseases such as autoimmune, cardiovascular, obesity, neural, soft tissues, bone, and cartilage.

Beneficial Effects

Curcumin ((1E,6E)-1,7-Bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione), the yellow biphenolic pigment isolated from turmeric (Curcuma longa), has various medicinal benefits through antioxidation, anti-inflammation, cardiovascular protection, immunomodulation, enhancing of the apoptotic process, and antiangiogenic property. We explored the effects of curcuminin vitro(10−5 M to 10−8 M) andin vivo(340 and 170 mg/kg b.w., oral) on Na+/K+ATPase (NKA), Na+/H+exchanger (NHE) activity, and membrane lipid hydroperoxides (ROOH) in control and experimental oxidative stress erythrocytes of Wistar rats. As a result, we found that curcumin potently modulated the membrane transporters activity with protecting membrane lipids against hydro-peroxidation in control as well as oxidatively challenged erythrocytes evidenced by stimulation of NKA, downregulation of NHE, and reduction of ROOH in the membrane. The observed results corroborate membrane transporters activity with susceptibility of erythrocyte membrane towards oxidative damage. Results explain the protective mechanism of curcumin against oxidative stress mediated impairment in ions-transporters activity and health beneficial effects.
