RESUMO

BACKGROUND: Cyanidin-3-O-glucoside (C3G), is an anthocyanin mainly found in berries, and can also be produced by microorganisms. It has been traditionally used as a natural coloring agent for decades. Recently, it has been investigated for its high antioxidant activity and anti-cancer attributes. C3G has low bioavailability and is sensitive to oxidation and gastric pH; therefore, it is encapsulated in nanoliposomes to enhance its bio-availability, targeted delivery- and efficacy against chronic disease. SCOPE AND APPROACH: In this review, the role of C3G nanoliposomes against major chronic diseases has been discussed. The focus was on research findings and the mechanism of action to affect the proliferation of cancer, neuro disease and cardiovascular problems. It also discussed the formulation of nanoliposomes, their role in nutraceutical delivery and enhancement in C3G bioavailability. KEY FINDINGS AND CONCLUSIONS: Data suggested that nanoliposomes safeguard C3G, enhance bioavailability, and ensure safe, adequate and targeted delivery. It can reduce the impact of cancer and inflammation by inhibiting the ß-catenin/O6-methylguanine-DNA methyltransferase (MGMT) pathway and upregulating miR-214-5p. Formation of C3G nanoliposomes significantly enhances the nutraceutical efficacy of C3G against major chronic disease therefore, C3G nanoliposomes might be a future-based nutraceutical to treat major chronic diseases, including cancer, neuro problems and CVD, but challenges remain in finding correct dose and techniques to maximize its efficacy.

RESUMO

The emergence of multidrug-resistant ESKAPE infections has emerged as a serious public health threat. Nosocomial infections are most often caused by ESKAPE bacteria. To combat multidrug-resistant ESKAPE, the research team used Valeriana Wallichii extracts and nanoparticles. The well diffusion technique was used to test antimicrobial activity on Muller Hinton agar medium. The FTIR, SEM and XRD techniques were used to characterize the nanoparticles synthesized in an environmentally benign manner. Both NPs performed better than extracts made with methanol and water in this investigation. The smallest zones of inhibition were shown against A. baumannii and Enterobacter cloacae, whereas the largest zones of inhibition were seen against E. faecium. However, NPs synthesized from shoot extracts exhibited remarkable effects against all MDR ESKAPE infections, with zones of inhibition of 23, 20, 12, 18, 22 and 14mm, respectively. Although E. faecium. had the largest inhibitory zone in both methanolic root and shoot extracts (19mm and 22mm, respectively), K. pneumonia and E. cloacae had the smallest zones when tested with these solvents. Water-based extracts inactivated multidrug-resistant bacteria. Our research show that extracts and nanoparticles have stronger antibacterial efficiency because biologically active substances including Terpenoids, Alkaloids, Phenol and Pholobutannins affect people and microbe.

RESUMO

Cirrhosis and liver cancer are both caused by hepatitis C virus (HCV) infection of the liver. Patients with HCV cirrhosis may be treated with one of many antiviral medications, depending on their specific genotype. Samples of cirrhotic HCV were obtained from 190 people at the Khyber Teaching Hospital and the Hayatabad Medical Complex in Peshawar, Pakistan. Multiplex and real-time PCR were used to assess the genotypes and viral loads of the samples, respectively. Sixty patients were given sofosbuvir plus daclatasvir with ribavirin, while the remaining 56 patients were given sofosbuvir with ribavirin for a period of 12-24 weeks. LFTs were also tracked both before and after therapy. Group I (sofosbuvir + daclatasvir) had a sustained virological response of 82.70 percent. Group II (sofosbuvir + daclatasvir with ribavirin) had an 86% sustained virological response, whereas group III (84% sustained virological response) received only ribavirin. When compared to other genotypes, genotype 3 showed the most impressive sustained virologic response (SVR) to the antiviral medicines. Based on the results of this trial, we propose sofosbuvir + daclatasvir ribavirin for the treatment of cirrhotic patients with various HCV genotypes since it produces the greatest sustained virological response.

RESUMO

High-intensity ultrasound (HIU) is considered one of the promising non-chemical eco-friendly techniques used in food processing. Recently (HIU) is known to enhance food quality, extraction of bioactive compounds and formulation of emulsions. Various foods are treated with ultrasound, including fats, bioactive compounds, and proteins. Regarding proteins, HIU induces acoustic cavitation and bubble formation, causing the unfolding and exposure of hydrophobic regions, resulting in functional, bioactive, and structural enhancement. This review briefly portrays the impact of HIU on the bioavailability and bioactive properties of proteins; the effect of HIU on protein allergenicity and anti-nutritional factors has also been discussed. HIU can enhance bioavailability and bioactive attributes in plants and animal-based proteins, such as antioxidant activity, antimicrobial activity, and peptide release. Moreover, numerous studies revealed that HIU treatment could enhance functional properties, increase the release of short-chain peptides, and decrease allergenicity. HIU could replace the chemical and heat treatments used to enhance protein bioactivity and digestibility; however, its applications are still on research and small scale, and its usage in industries is yet to be implemented.

RESUMO

Recently protein has gained eminence due to awareness and demand for healthy food. Potato proteins are extracted from potato fruit juice and industrial potato waste; its nutritional and functional values have been found more significant than other vegetables and cereal proteins. Potato proteins can be easily extracted by various separation techniques, including an ion exchange (IEX) and expanded bed adsorption (EBA), and their functional properties can be modified for desire purposes. It contains many essential amino acids necessary for the human body, with an amino acid score (AAS) of 65%. Recent research on potato proteins resulted in several descriptions of new technologies to produce food-grade potato protein. It has recently drawn more attention as a protein source for human consumption, especially as an allergy free protein source and selective activity against cancer cells. Growing shreds of evidence have highlighted that potato protein can be used in many upcoming nutraceuticals and allergy-free food products. Therefore it is gaining more attention from nutritionists and food scientists. This review has summarized the recent knowledge on the nutritional and functional aspects of potato proteins, especially its non-allergic properties, enhancement in functional properties, and possible future-based products.
