Obesity is a global health concern with numerous comorbidities, including cardiovascular diseases, type 2 diabetes, and certain cancers. Carotenoids, found in a variety of natural sources like fruits and vegetables, are known for their potential health benefits. Emerging research suggests that certain carotenoids may play a major role in combating obesity through mechanisms involving inflammation, oxidative stress, and lipid metabolism. Understanding the influence of carotenoids on metabolic health could offer valuable revelation about obesity management strategies. To summarize the main findings on carotenoids that help in the management and prevention of obesity, exploring their potential benefits in weight management, metabolic health, and overall well-being. An extensive literature survey was done on the management of obesity using PubMed, Elsevier, ScienceDirect, and Springer. The results were then filtered based on the titles, abstracts, and accessibility of the complete texts. The search engine Google Scholar was accessed for the literature data mining. This review highlights the diverse functions of carotenoids, such as their antioxidant properties, anti-inflammatory effects, and regulation of lipid metabolism, which contribute to their potential role in combating obesity. Studies suggest that carotenoids may help reduce adiposity, lipid accumulation, improve insulin sensitivity, and promote overall metabolic health, making them promising candidates for obesity management. Obesity is synonymous with the appearance of major diseases and an overall decline in physical and mental performance. Overall, the findings of this review endorse the possible application of carotenoids as a nutritional supplement for the management and prevention of obesity. Further research is needed to clarify the mechanisms underlying the beneficial impacts of carotenoids on obesity-related consequences and to optimize their utilization in clinical practice and public health campaigns.

Introduction: Colorectal cancer is a complex condition influenced by genetic mutations and environmental factors. Due to its intricate nature, the diagnosis and treatment of this condition require a comprehensive approach that considers individual circumstances. The study aimed to identify genes linked with colorectal cancer and their therapeutic agents from natural bioactive compounds.

Methods: The significantly prognostic differentially expressed genes (DEGs) were screened out from NCBI Gene Expression Omnibus (GEO) datasets. A protein-protein interaction network was constructed using STRING Database, and key genes were identified using Network Analyzer and CytoNCA plugins within Cytoscape. Further analysis involved functional annotations, and biological pathways analysis, SRC mechanism to uncover the role of SRC in CRC. Additionally, we performed virtual screening and molecular docking, Physiochemical property analysis along with MD simulation study to propose suitable natural compounds for promising therapeutic targets.

Results: The study conducted differential gene expression analysis, identifying 3621 statistically significant genes, with 1467 upregulated and 2154 downregulated. The top ten genes with the highest degree, betweenness centrality, and closeness centrality in the PPI network were selected as key genes. The SRC gene was found to have the highest degree and closeness centrality. Functional annotation and pathway analysis of key genes with a specific focus on the SRC mechanism revealed that the SRC's role in activating the RAS-RAF-MEK-ERK and Wnt/β-catenin pathways in CRC cells, promoting proliferation and invasion. Molecular modelling of SRC led to the screening of phyto-compounds from tropical fruits, with Rutinexhibiting a higher docking score compared to FDA-approved anticancer drugs. MD simulations over 100 ns and the post-MD analysis i.e. RMSD, SASA, RMSF, FEL, RG, Hydrogen bond, PCA, and MMPBSA, comprehended the stable and robust interactions of a protein-ligand complex. These findings suggest Rutin's potential as a potent natural molecule for treating CRC. The study concludes that SRC plays a pivotal role in CRC, influencing cellular processes critical to cancer development and Rutin has been found to be a promising SRC inhibitor, suggesting a potential alternative therapeutic strategy for CRC. The consistent molecular interactions of Rutin necessitate further validation through wet lab experiments, offering hope for individuals affected by CRC.

Background: Distillery vinasse is one of the promising bio-fertilizers, as it contains significant amounts of essential chemical elements, allied with sorghum that is widely used in the diet of ruminant animals and has been considered as an alternative to the production of other cereals or forages. This study aimed to evaluate saccharin sorghum silage from fertilization with vinasse.

Methods: The research was conducted using the BRS-511, CR-1339, and CR-1342 geno-types. The silage was held for 170 days after sowing, with experimental design in blocks with triple factorial (genotypes x fertilization x inoculation) totaling 54 installments. At 95 days, the silos were opened for sample collection and analysis bromatological analysis.

Results: The results indicate the primary source of variation was genotype, characterizing them with different potentials in productivity and better results for BRS-511, CR-1339, and CR-1342. The bromatological results indicate good quality for CR-1339 and CR-1342 hybrids, however, better digestability for BRS-511. There was no observable difference between the factors of fertilization. The inoculation additive assists in the reduction of lignin appears to be high. PCA analysis showed differences between cultivars (BRS-511, CR-1339, and CR-1342) and fertili-zation. However, the PCAs showed the genotypes show similar results with conventional ferti-lization and sugarcane vinasse.

Conclusion: The study reflected the possibility of producing sweet sorghum silage with soil sugarcane vinasse fertilization as fertilizer.

The massive and uncontrolled use of petroleum-based plastic food packaging has resulted in serious environmental problems. As a result, the food packaging industry should improve packaging materials based on biodegradable polymers, such as chitosan. Edible food coating maintains and improves the shelf life and condition of packaged foods. Researchers have widely investigated the potential applications of biodegradable natural polymers, such as chitosan, cellulose, starch, whey protein, and gelatin in the food packaging industry. Among the natural biodegradable materials available, chitosan and its derivatives have attracted great interest because they have antimicrobial, antifungal, and metal-chelating properties. They are biodegradable polysaccharides and are non-toxic; therefore, they are considered perfect materials for food coating. Adding other active materials, such as fruit extracts, phenolic compounds, and essential oils, can significantly enhance the antimicrobial and antioxidant capacity of chitosan-based packaging materials. Thus, this article investigates the recent updates in food packaging applications based on chitosan essential oil composites.

Background: Sewage sludge is a by-product of urbanization that poses environmental and health challenges. However, it can also be a valuable source of organic matter and nutrients for agriculture.

Results: The results showed that the organic fertilizers significantly improved the wheat performance in terms of plant height, biomass accumulation, chlorophyll content, leaf area and other yield parameters. Furthermore, the fertilizers ameliorated soil physicochemical attributes and augmented the availability of macro- and micronutrients. Importantly, levels of heavy metals in soil and wheat grains remained within permissible limits, affirming the safety and appropriateness of these fertilizers for wheat cultivation.

Conclusion: This study underscores the efficient utilization of treated Ganga sludge as a valuable organic fertilizer source, proposing a sustainable and ecologically sound approach for sewage sludge management and enhancement of agricultural productivity.

Introduction: Bio-cellulose is a type of cellulose that is produced by some particular group of bacteria, for example, Komagataeibacter (previously known as Acetobacter), due to their natural ability to synthesize exopolysaccharide as a byproduct. Gluconacetobacter xylinus is mostly employed for the production of bio-cellulose throughout the world. Therefore, exploring other commonly available strains, such as Komagataeibacter aceti (Acetobacter aceti), is needed for cellulose production.

Methods: Bio-cellulose is one of the most reliable biomaterials in the limelight because it is highly pure, crystalline, and biocompatible. Hence, it is necessary to enhance the industrial manufacturing of bio-cellulose with low costs. Different media such as fruit waste, milk whey, coconut water, sugarcane juice, mannitol broth, and H&S (Hestrin and Schramm's) broth were utilized as a medium for culture growth. Other factors like temperature, pH, and time were also optimized to achieve the highest yield of bio-cellulose. Moreover, after the synthesis of biocellulose, its physicochemical and structural properties were evaluated.

Results: The results depicted that the highest yield of bio-cellulose (45.735 mg/mL) was found at 30 °C, pH 5, and on the 7th day of incubation. Though every culture media experimented with synthesized bio-cellulose, the maximum production (90.25 mg/mL) was reported in fruit waste media. The results also indicated that bio-cellulose has high water-holding capacity and moisture content. XRD results showed that bio-cellulose is highly crystalline in nature (54.825% crystallinity). SEM micrograph demonstrated that bio-cellulose exhibited rod-shaped, highly porous fibers. The FTIR results demonstrated characteristic and broad peaks for O-H at 3336.25 cm^-1, which indicated strong O-H bonding. The thermal tests, such as DSC and TGA, indicated that bio-cellulose is a thermally stable material that can withstand temperatures even beyond 500 °C.

Conclusion: The findings demonstrated that the peel of fruits could be utilized as a substrate for synthesizing bio-cellulose by a rather cheap and easily available strain, Komagataeibacter (Acetobacter aceti MTCC 3347). This alternative culture media reduces environmental pollution, promotes economic advantages, and initiates research on sustainable science.

Vegetables and fruits are highly perishable agricultural commodities cultivated all over the world. However, inadequate handling practices have led to significant postharvest losses of these agricultural commodities, as well as the wastage of valuable resources, such as time and money. Hence, it can be observed that cultivators often experience significant financial setbacks as a result of inadequate comprehension regarding the nature and origins of these losses, insufficient preservation practices, and ineffective approaches to transportation and marketing. In addition, the utilization of suitable chemical agents during both the pre- and postharvest phases has the potential to prolong the shelf life of agricultural products. This preservation technique safeguards vegetables and fruits from pathogenic organisms and other forms of environmental harm, thereby enabling their availability for an extended duration. Therefore, this review proposes a methodology for managing fruits and vegetables postharvest to minimize losses and optimize returns.

In recent years, the growing demand for herbal-based formulations, including functional foods, has acquired significant attention. This study highlights historical, botanical, ecological, and phytochemical descriptions and different extraction mechanisms of Ocimum sanctum utilized in its processing. Besides this, it explores the utilization of Ocimum sanctum as a functional food ingredient in various food products such as bakery products (biscuits, bread), dairy products (herbal milk, cheese), and beverages (tea, juice, wine) while focusing on their evaluation parameters, preparation techniques, and pharmacological activities. In terms of other pharmacological properties, Ocimum sanctum-infused functional foods exhibited cognitiveenhancing properties, adaptogenic qualities, anti-obesity effects, gastroprotective, antiinflammatory, hypoglycemic, and immuno-modulatory effects. Thus, the diverse properties of Ocimum sanctum offer exciting opportunities for the development of functional foods that can promote specific health issues, so future research should focus on developing and analyzing novel Ocimum sanctum-based functional foods to meet the growing demand of the functional food industry.
