Resveratrol (3,4,5-trihydroxystilbene) is a member of natural and plant-derived chemicals, which is known as polyphenols and it is getting more consideration because of its various health assistances. Largely in the case of neurological problems, cardiovascular disease, antiviral, cancer, antiaging. Although in the past few years, it has been shown that the families of enzymes Sirtuins, particularly situin1 (SIRT1), have an antiaging action. Thus, the natural compound resveratrol shows a very strong activation of SIRT1 and also shows antioxidant properties. The antioxidant effect mainly elicited by the inhibition of important pathways like the NF-ĸβ pathway. This review highlights the antiviral mechanism of resveratrol in human and animal viral infections. And also, information about cancer-related like colorectum cancer, skin cancer and lung cancer are also mentioned. Resveratrol also gives additional cardioprotective and vasoprotective properties, which include antiatherosclerotic action. Overall observation shows that resveratrol has a high therapeutic potential in the treatment of cardiovascular disease, anti-aging, antiviral and in the treatment of cancer.

The aim of the present work was to compare the wound healing efficacy of different topical dosage forms such as β cyclodextrin complex gel, liposomal gel, and ointment on the rat model. Simvastatin was used as a drug, β cyclodextrin was used as a complexing agent to enhance solubility, L α Phosphatidylcholine as a phospholipid, and cholesterol as a stabilizing agent. Liposomes were prepared by thin-film hydration method, β cyclodextrin complexes of simvastatin were prepared by spray drying technique, and the ointment was prepared in simple method. Beta cyclodextrin gels and liposomal gels were prepared by direct incorporation of spray-dried products and lyophilized liposomes into Carbopol gel. The gel was evaluated for drug content, particle size, viscosity, spreadability, surface morphology, in-vitro drug release studies, skin irritation study, and wound healing activity studies. FTIR and DSC studies showed no chemical interaction between the drug and excipients. The particle size of β cyclodextrin complexes was in the range of 0.5 μm to 2.5 μm and for liposomes 163 nm to 725 nm. The in-vitro drug release was 96.7 % at the end of the sixth hour for β cyclodextrin gel, 29.7 % at the end of the sixth hour for liposomal gel, and 96.2 % at the end of 3 hours for ointment. Wound healing activity studies were carried out for 21 days on albino wrister rats, a period of epithelization, and rate of wound contraction was measured on 4, 8, 14, 16, and 21 days. Simvastatin ointment showed a significant effect on wound healing in the rat model compared to β-cyclodextrin gel and liposomal gel. Hence, Simvastatin ointment could be a potential dosage form for clinical utility on wound healing.

The research aimed to formulate and prepare hydrogel of low molecular weight chitosan nanoparticles with the help of antifungal agents such as clotrimazole and Nystatin for the topical application. Using the ionic gelation process, placebo and nanoparticles containing drugs were prepared. By cationic interaction is suitable for pH, and gel sodium tripolyphosphate is used as a crosslinker which cross-links the chitosan particles to form the gel, interaction between drug and polymer was observed during the formulation development. Formulated nanoparticle with chitosan and nystatin and clotrimazole showed the mean diameter 273.7nm, 983nm, and 501nm. Clotrimazole and Nystatin had encapsulation capacity was about 74.6% and 63.0%, respectively. In vitro drug release at pH 4.7 chitosan molecules are examined for the version of clotrimazole and nystatin.it has noticed that both the formulation shows sustained drug release about 12 hours. Using SEM, nanoparticles are directed for surface morphology character; it shows that nanoparticles are smooth and spherical in structure. Chitosan itself has the antimicrobial property; it was carried out for the antifungal activity against the fungus Candida Albicans along with the prepared formulations drugs for the comparative study. And the result showed that clotrimazole had maximum fungal growth inhibition next followed by the nystatin and chitosan is least. This inhibitory effect was due to the parameter such as zeta potential and particle size of chitosan nanoparticles. And it shows the least antifungal activity of nanoparticles, which are formulated from the TMC. Hence CTZ and Chitosan were formulated and applied as a natural antifungal agent into nanoparticle to increase the fungal activity. According to the ICH Q1A (R2) guidelines, stability studies are conducted to prove no degradation of the drug. The prepared formulation of chitosan nanoparticles based hydrogel incorporated with clotrimazole and nystatin are promising and significant properties for the efficient treatment of topical fungal infections

Measurement of arterial oxygen saturation (SpO 2 ), end-tidal carbon dioxide (E T CO 2 ) and pH are linked in this article as they all can be measured by photometric methods. The underlying physical principles, Beer–Lambert law, and other methods of measurement of pH are outlined including advantages and limitations of these techniques.

Even though Meckel's diverticulum is the most common anomaly of the gastrointestinal tract, it is asymptomatic in the majority of cases. With life time complication rate of 4%, it is an uncommon cause of intestinal obstruction in adult. We report a case of Meckel's diverticulum attached to undescended testis presenting as acute abdomen in an adult with intestinal obstruction. The patient a 36-year-old man presented with acute abdominal pain, vomiting and distension. On examination, there was distension of the abdomen with tenderness and guarding rigidity and absence of testis in right scrotum. Erect X-ray of abdomen showed multiple air fluid levels suggestive of intestinal obstruction. A diagnosis of acute intestinal obstruction was made and the patient was resuscitated and taken to the operation theater after adequate hydration and antibiotic cover. On exploration, it was found that Meckel's diverticulum attached to undescended testis with diverticular band forming an entangled mass, which caused complete obstruction of the bowel. It was treated successfully with resection of diverticulum and the band followed by a bowel anastomoses and orchidectomy. We conclude that it is indeed rare for two different congenital anomalies coexisting together to cause intestinal obstruction in an adult patient. High clinical suspicion is required to diagnose such rare congenital abnormality which if followed promptly by surgical intervention would lead to a satisfactory outcome.
