Fruit extracts have natural bioactive molecules that are known to possess significant therapeutic potential. Traditionally, metallic nanoparticles were synthesized via chemical methods, in which the chemical act as the reducing agent. Later, these traditional metallic nanoparticles emerged as the biological risk, which prompted researchers to explore an eco-friendly approach. There are different eco-friendly methods employed for synthesizing these metallic nanoparticles via the usage of microbes and plants, primarily via fruit extract. These explorations have paved the way for using fruit extracts for developing nanoparticles, as they eliminate the usage of reducing and stabilizing agents. Metallic nanoparticles have gained significant attention, and are used for diverse biological applications. The present review discusses the potential activities of phytochemicals, and it intends to summarize the different metallic nanoparticles synthesized using fruit extracts and their associated pharmacological activities like anti-cancerous, antimicrobial, antioxidant and catalytic efficiency.
Cancer is a serious and significantly progressive disease. Next to cardiovascular disease, cancer has become the most common cause of mortality in the entire world. Several factors, such as environmental factors, habitual activities, genetic factors, etc., are responsible for cancer. Many cancer patients seek alternative and/or complementary treatments because of the high death rate linked with cancer and the adverse side effects of chemotherapy and radiation therapy. Traditional medicine has a long history that begins with the hunt for botanicals to heal various diseases, including cancer. In the traditional medicinal system, several plants used to treat diseases have many bioactive compounds with curative capability, thereby also helping in disease prevention. Plants also significantly contributed to the modern pharmaceutical industry throughout the world. In the present review, we have listed 33 medicinal plants with active and significant anticancer activity, as well as their anticancer compounds. This article will provide a basic set of information for researchers interested in developing a safe and nontoxic active medicinal plant-based treatment for cancer. The research will give a scientific foundation for the traditional usage of these medicinal herbs to treat cancer.
The tree Rhododendron arboreum belongs to the Ericaceae family, which harbours the entire Himalayan range. In this study, flowers and leaves of R. arboreum were selected from the Mussoorie area in the district of Dehradun (Uttarakhand). Plant extracts were obtained by using hexane, distilled water, acetone, 80% methanol and ethyl acetate solvents in an orbital shaker. The activity of the extracts against Bacillus cereus, Shigella spp., Staphylococcus aureus, and Escherichia coli was investigated using an agar well diffusion procedure, and the synergistic interaction of the extracts with conventional antibiotics, including norfloxacin and ciprofloxacin, was examined. Phytochemicals of R. arboreum were obtained from PubChem, and a target protein was rebuilt using the RCSB protein data bank. The docking approach was carried out via AutoDock vina software with penicillin binding protein (3VSL) to validate the microbe interactions and bioactive molecules, whereas Molinspiration and Swiss ADME servers were used to determine the Lipinski rule of 5 and perform drug-likeness analysis, respectively. Protox II and AdmetSAR tools were used to screen phytoconstituent toxicity. Flower and leaf extracts exhibited the highest yields (3.06 ± 0.9% and 2.53 ± 1.01%, respectively) in methanol. Phenolics, alkaloids, carbohydrates, flavonoids, steroids, amino acids, cardiac glycosides, tannin, protein, and saponin were qualitatively found. Synergistic activity against B. cereus and E. coli was observed for aqueous leaf extracts, while methanol, ethyl acetate and aqueous extracts of flowers and leaves exhibited synergism against Shigella and S. aureus. Ethyl acetate extracts of flowers and leaves are the best synergistic enhancer. According to in silico data obtained from an in silico study, the best phytocompounds and prospective antibacterial agents are epifriedelanol and campanulin.
Microorganisms and microbial products have become increasingly important research topics because of the sustainability benefits of their industrially important products. Enzymes formed by fungus and bacteria are mainly used in industry to produce different types of products. Microbes are ubiquitous in nature and present with various strains. Detecting and isolating the best strain and achieving efficient product separation are required to achieve an economically viable process. Advancing microbial screening techniques requires a multidisciplinary approach, with input from chemists, engineers, and microbiologists. This paper provides an overview of industrially important microbes such as fungi, yeasts, and bacteria. It also focuses on microbial collection, selection strategies and techniques, culture storage, screening methods for microbial products, and future potential.
The quality and safety of fermented milk products, which make up a sizeable portion of human nutrition, are greatly influenced by both the milk itself and the starting cultures employed to ferment it.Lactic acid bacteria (LAB) create a variety of metabolites throughout the fermentation process, altering the organoleptic properties of the substrates.The final product's nutritional value and digestibility are enhanced by fermentation of the raw materials, which also adds vitamins, vital amino acids, and fatty acids.The quality and safety of fermented milk products, which make up a sizeable portion of human nutrition, are greatly influenced by both the milk itself and the starting cultures employed to ferment it.The inhibition of the growth of pathogenic microbes, which lowers the likelihood of the emergence of foodborne diseases, is another crucial function of LAB.A variety of pathogenic bacteria are frequently present in raw (unpasteurized) milk, and other raw materials; these pathogenic bacteria should be removed during the fermentation process.As a result, a variety of LAB metabolites, such as hydrogen peroxide, organic acids, and bacteriocins, function as bio preservative agents, enhancing food safety and lengthening the shelf life of the finished products.
Nanoparticles (NPs) have uniform chemical composition, size, and morphology. Microorganisms are of great interest in Nanoparticle synthesis. The green production of nanomaterials occurs either intracellularly or extracellularly. Gold and silver nanoparticles are mostly synthesised by the enzymatic degradation of metal ions. The produced NPs are characterized by different instruments such as ultraviolet visible, dynamic light scattering, x-ray diffraction, scanning electron microscope, transmission electron microscope, etc. Our review discusses the various biomedical applications of gold and silver nanoparticles synthesized by microbes via intracellular and extracellular mechanisms.

Acute kidney infection (AKI) occurred by tubular necrosis and glomerular dysfunction caused by many factors. SARS CoV-2 infection identified to cause fatal AKI. This paper aims to review the effect of covid-19 infection on the failure of the kidney and its mechanism. It identified that the SARS-CoV-2 received by the targeted cell by Angiotensin-converting enzyme 2 (ACE2). After the virus received by the target cells, it induces the production of pro-inflammatory cytokines such as tumor necrosis factor (TNF), interleukin (IL)-1, and interferons (IFN) by immune cells and causes cytokine storm. The pro-inflammatory cytokines are again responsible to induce the secretion of cyclooxygenase‑2 (COX‑2), which causes inflammation and pain as well it stimulates the iNOS enzyme to produce NO which allows the vasodilation of renal arteries. The increased production of NO by iNO enhanced the vasodilation of arteries, and allows the adhesion of neutrophils to the artery, and causes damage to glomerulus and tubules. Hence, the most likely sustainable intervention could be the application of angiotensin-converting enzyme 2 (ACE2) inhibition by the receptors of the target cells in these vital organs to reduce sever destruction during treatment at the early stage of infection.
