Effects of Melatonin on Diabetic Neuropathy and Retinopathy

Diabetes mellitus (DM) leads to complications, the majority of which are nephropathy, retinopathy, and neuropathy. Redox imbalance and inflammation are important components of the pathophysiology of these complications. Many studies have been conducted to find a specific treatment for these neural complications, and some of them have investigated the therapeutic potential of melatonin (MEL), an anti-inflammatory agent and powerful antioxidant. In the present article, we review studies published over the past 21 years on the therapeutic efficacy of MEL in the treatment of DM-induced neural complications. Reports suggest that there is a real prospect of using MEL as an adjuvant treatment for hypoglycemic agents. However, analysis shows that there is a wide range of approaches regarding the doses used, duration of treatment, and treatment times in relation to the temporal course of DM. This wide range hinders an objective analysis of advances and prospective vision of the paths to be followed for the unequivocal establishment of parameters to be used in an eventual therapeutic validation of MEL in neural complications of DM.

Effects of Curcumin in Management of Endometriosis a Hormonal Disorder Disease in Female

A disorder in which endometrial tissues develop outer side the uterus or uterine cavity is called as endometriosis. It affects mainly females in their reproductive years, and is an oestrogen-dependent condition. Endometriosis a gynaecological disease or disorders, occurs in about 10% of female in reproductive age and in upto 50% of females with in-fertility. It is serious type of Hormonal disease or disorders in female which is caused due to hormonal imbalance these diseases totally change the quality of womens life. Decreased quality of life is the most significant predictor of direct health care and total costs so avoid this next step greater way to take care “Prevention is always better than cure”. Curcumin is a natural polyphenolic compound extracted from the spice, turmeric and has been reported to evidence anti-inflammatory (agent which reduce inflammation), antioxidant (the agent which reduce oxidation), and anti-proliferative properties via the modulation of multiple cellular. However, it remains to be determined whether effect of curcumin affects in the management of process of endometriosis. Turmeric contain especially its most active compound Curcumin have many scientifically proven health benefits, it’s a potent Anti-inflammatory and antioxidant and may also help improve symptoms of endometrosis.

Cytotoxic Effect of Pterocarpus santalinus and stevia-based Mouthwash - A Lab-based Analysis

Introduction: Red sandalwood called as Pterocarpus santalinus is esteemed for the rich red colour of its wood. Pterocarpus santalinus used as astringent, analgesic and anti-inflammatory agent. Also helpful in treating skin illness, fistula, haemorrhage and ulcers. Stevia rebaudina is a food additive with lingering flavor. The wood isn't aromatic. The tree isn't to be mistaken for the fragrant Santalum sandalwood trees that fill locally in South India. In the present study we have prepared Pterocarpus santalinus and stevia-based mouthwash and evaluated its cytotoxic activity. Materials and Methods: 1g of Pterocarpus santalinus and stevia were measured and 50 ml of distilled water were measured. Both were mixed together to make the aqueous extract. To that 10 nauplii were slowly added and the cytotoxic activity is analysed by the number of live nauplii counts. Results: First day, Nauplii were grown in the medium and it hatches out after 24 hours. Second day, Mouthwash was added according to the concentration. Nauplii were collected and for each concentration 10 nauplii were added. After adding the nauplii, cytotoxicity well as undisturbed for one full day to analyze the inhibition of growth. Third day, nauplii were counted and cytotoxicity of mouthwash was evaluated. Statistical analysis showed significant reduction in the nauplii count (P<0.05). Conclusion: Medicinal plants cure many severe diseases. Application of medicinal plants in the field of medicine should be improved. Based on the results recorded in the present study, it is concluded that Pterocarpus santalinus has a potential cytotoxicity activity. Hence the present study findings provide a beautiful base for some of the medicinal uses of Pterocarpus santalinus.

The role of K-channels in the formation of a nociceptive signal in the rat trigeminal nerve

The central problem of this work is to elucidate the mechanisms of pain in migraine and to establish the role of Kv channels in regulating the excitability of meningeal afferents of the trigeminal nerve that form a pain signal in migraine. The study was conducted on a preparation of an isolated rat skull. It was found that Kv-channel inhibitors 4-aminopyridine (100 microns and 1 mM) and tetraethylammonium (5mm) lead to an increase in the excitability of trigeminal nerve afferents, at the same time, this effect was partially removed by a nonsteroidal anti–inflammatory agent - naproxen, and was not sensitive to sumatriptan, a classic anti-migraine drug. Key words: migraine, K-channels, trigeminal nerve, 4-aminopyridine, tetraethylammonium, naproxen, sumatriptan.

5-Dodecanolide, a Compound Isolated from Pig Lard, Presents Powerful Anti-Inflammatory Properties

Background: Pork lard (PL) is traditionally used as an anti-inflammatory agent. We propose to demonstrate the anti-inflammatory properties of PL, and elucidate which compounds could be responsible for the anti-inflammatory effects. Methods: The anti-inflammatory effects of PL were tested in a rat model of zymosan-induced hind paw inflammation. Further, the hydroalcoholic extract from PL was obtained, the composition analyzed, and the anti-inflammatory activity of the extracts and isolated components assayed using immune cells stimulated with lipopolysaccharide (LPS). Results: Applying the ointment on the inflamed rat feet reduced the foot diameter, foot weight, and activities of antioxidant enzymes and inflammatory markers of circulating neutrophils. The main components of the hydroalcoholic extract were 5-dodecanolide, oleamide, hexadecanoic acid, 9-octadecenoic acid, hexadecanamide, and resolvin D1. Conclusions: PL reduces the immune response in an animal model stimulated with zymosan. Hydroalcoholic PL extract and its components (5-Dodecanolide, Oleamide, and Resolvin D1) exerted an anti-inflammatory effect on LPS-stimulated neutrophils and peripheral mononuclear cells reducing the capability to produce TNFα, as well as the activities of antioxidant and pro-inflammatory enzymes. These effects are attributable to 5-dodecanolide, although the effects of this compound alone do not reach the magnitude of the anti-inflammatory effects observed by the complete hydroalcoholic extract.

A new p65 isoform that bind the glucocorticoid hormone and is expressed in inflammation liver diseases and COVID-19

Inflammation is a physiological process whose deregulation causes some diseases including cancer. Nuclear Factor kB (NF-kB) is a family of ubiquitous and inducible transcription factors, in which the p65/p50 heterodimer is the most abundant complex, that play critical roles mainly in inflammation. Glucocorticoid Receptor (GR) is a ligand-activated transcription factor and acts as an anti-inflammatory agent and immunosuppressant. Thus, NF-kB and GR are physiological antagonists in the inflammation process. Here we show that in mice and humans there is a spliced variant of p65, named p65 iso5, which binds the corticosteroid hormone dexamethasone amplifying the effect of the glucocorticoid receptor and is expressed in the liver of patients with hepatic cirrhosis and hepatocellular carcinoma (HCC). Furthermore, we have quantified the gene expression level of p65 and p65 iso5 in the PBMC of patients affected by SARS-CoV-2 disease. The results showed that in these patients the p65 and p65 iso5 mRNA levels are higher than in healthy subjects. The ability of p65 iso5 to bind dexamethasone and the regulation of the glucocorticoid (GC) response in the opposite way of the wild type improves our knowledge and understanding of the anti-inflammatory response and identifies it as a new therapeutic target to control inflammation and related diseases.
