Micronutrients Importance in Cancer Prevention-Minerals.

Cancer, a non-communicable disease with diverse kinds is one of the major global problems with high incidence and no proven method to prevent or treat. Minerals including trace elements are significant micronutrients for preserving the body's typical physiological function. In contrast to extremely processed industrial food, they are rich in natural sources of food and frequently included in nutritional supplements. The daily intake, storage capacities, and homeostasis of micronutrients depend on specific dietary practices in contemporary civilization and can be disturbed by various malignancies. Varied minerals have different effects on the status of cancer depending on how they affect these pathways. The outcomes could differ depending on the mineral such as calcium's supply and the cancer's location. A mineral called zinc helps the immune system function better and aids in wound healing. On the other hand, selenium exhibits anti-oxidant functions and has a dose-response relationship with many cancer types. However, this component can make the patient's condition worse. Although the body produces free radicals when iron is deficient, anaemia affects a patient's quality of life and ability to receive therapy. This chapter compiles the knowledge of minerals connected to unusual accumulation or depletion states in various malignancies.

Dietary Pattern and Cancer.

Diet play an important role in the development of cancer. A lot of research has been done on the role of individual nutrients or phytochemicals and cancer risk. Both harmful and beneficial associations of this nutrient have been observed with cancer. However, there is an interaction of individual dietary constituents to influence disease risk. On the other hand, examining the diet as a whole as is done in dietary patterns research may produce more accurate estimates and data that can be more easily translated into dietary recommendations. Dietary patterns and cancer research are becoming increasingly common in the epidemiology literature, and novel dietary patterns are being generated at a rapid pace. However, major issues remain over whether one general "healthy" dietary pattern can be suggested for cancer prevention or whether several diets should be advocated for different forms of cancer protection. It is challenging to study typical human diet in animal model that is appropriate for cancer prevention. Some dietary patterns, such as the ketogenic diet or macronutrient composition alteration, have been investigated more extensively in animal models than in humans in terms of cancer prevention, and bigger human observational studies are now needed to advise dietary guidelines. The question of whether to adapt nutritional guidelines to population subgroups based on susceptibility factors (for example, family history, sex, age, other lifestyle factors or comorbidities, metabolomics signatures, or microbiota-based profiles) is still open and will be crucial in moving the field forward.

Polyphenolic characterization and biological assessment of Acacia nilotica (L.) wild. Ex delilie: An In vitro and In vivo appraisal of wound healing potential.

ETHNOPHARMACOLOGICAL RELEVANCE: Acacia nilotica (L.) Wild. Ex Delilie is a shrub with significant ethnomedicinal stature. Therefore, in the undertaken study, its wound healing attributes are determined. AIM OF THE STUDY: The current study provided evidence of the traditional use of A. nilotica species and conferred A. nilotica bark extract as a potent candidate for wound healing agents. MATERIALS & METHODS: A. nilotica leaves extract (ANL-E); A. nilotica bark extract (ANB-E), and A. nilotica stem extract (ANS-E) were prepared using methanol-chloroform (1:1). Phytochemical analysis was performed using gallic acid equivalent (GAE) total phenolic content (TPC), quercetin equivalent (QE) total flavonoid content (TFC) assays and High-performance liquid chromatography (HPLC). In vitro antioxidant potential (free radical scavenging activity (FRSA), total antioxidant capacity (TAC), and ferric reducing antioxidant power (FRAP) assay), antibacterial activity (broth microdilution method) and hemolytic analysis was carried out. Wound healing proficiency of ANB-E was determined by wound excision model followed by estimating hydroxyproline content and endogenous antioxidant markers. RESULTS: Maximum phenolic and flavonoid content were depicted by ANB-E i.e., 50.9 ± 0.34 µg gallic acid equivalent/mg extract and 28.7 ± 0.13 µg quercetin equivalent/mg extract, respectively. HPLC analysis unraveled the presence of a significant amount of catechin in ANL-E, ANB-E and ANS-E (54.66 ± 0.02, 44.9 ± 0.004 and 31.36 ± 0.02 µg/mg extract) respectively. Highest percent free radical scavenging activity, total antioxidant capacity, and ferric reducing action power (i.e., 93.3 ± 0.42 %, 222.10 ± 0.76, and 222.86 ± 0.54 µg ascorbic acid equivalent/mg extract) were exhibited by ANB-E. Maximum antibacterial potential against Staphylococcus aureus was exhibited by ANB-E (MIC 12.5 µg/ml). Two of the extracts i.e., ANL-E and ANB-E were found biocompatible with less than 5 % hemolytic potential. Based upon findings of in vitro analysis, ANB-E (10, 5, and 2.5 % w/w, C1, C2, and C3, respectively) was selected for evaluating its in vivo wound healing potential. Maximum contraction of wound area and fastest epithelization i.e., 98 ± 0.05 % and 11.2 ± 1.00 (day) was exhibited by C1. Maximum hydroxyproline content, glutathione, catalase, and peroxidase were demonstrated by C1 i.e., 15.9 ± 0.52 µg/mg, 9.3 ± 0.17 mmol/mg, 7.2 ± 0.17 and 6.2 ± 0.14 U/mg, respectively. Maximal curbed lipid peroxidation i.e., 0.7 ± 0.15 mmol/mg was also depicted by C1. CONCLUSIONS: In a nutshell, the current investigation endorsed the wound healing potential of ANB-E suggesting it to be an excellent candidate for future studies.

Unlocking the interaction of organophosphorus pesticide residues with ecosystem: Toxicity and bioremediation.

Organophosphorus adulteration in the environment creates terrestrial and aquatic pollution. It causes acute and subacute toxicity in plants, humans, insects, and animals. Due to the excessive use of organophosphorus pesticides, there is a need to develop environmentally friendly, economical, and bio-based strategies. The microbiomes, that exist in the soil, can reduce the devastating effects of organophosphates. The use of cell-free enzymes and yeast is also an advanced method for the degradation of organophosphates. Plant-friendly bacterial strains, that exist in the soil, can help to degrade these contaminants by oxidation-reduction reactions, enzymatic breakdown, and adsorption. The bacterial strains mostly from the genus Bacillus, Pseudomonas, Acinetobacter, Agrobacterium, and Rhizobium have the ability to hydrolyze the bonds of organophosphate compounds like profenofos, quinalphos, malathion, methyl-parathion, and chlorpyrifos. The native bacterial strains also promote the growth abilities of plants and help in detoxification of organophosphate residues. This bioremediation technique is easy to use, relatively cost-effective, very efficient, and ensures the safety of the environment. This review covers the literature gap by describing the major effects of organophosphates on the ecosystem and their bioremediation by using native bacterial strains.

A comprehensive review of discovery and development of drugs discovered from 2020-2022.

To fully evaluate and define the new drug molecule for its pharmacological characteristics and toxicity profile, pre-clinical and clinical studies are conducted as part of the drug research and development process. The average time required for all drug development processes to finish various regulatory evaluations ranges from 11.4 to 13.5 years, and the expense of drug development is rising quickly. The development in the discovery of newer novel treatments is, however, largely due to the growing need for new medications. Methods to identify Hits and discovery of lead compounds along with pre-clinical studies have advanced, and one example is the introduction of computer-aided drug design (CADD), which has greatly shortened the time needed for the drug to go through the drug discovery phases. The pharmaceutical industry will hopefully be able to address the present and future issues and will continue to produce novel molecular entities (NMEs) to satisfy the expanding unmet medical requirements of the patients as the success rate of the drug development processes is increasing. Several heterocyclic moieties have been developed and tested against many targets and proved to be very effective. In-depth discussion of the drug design approaches of newly found drugs from 2020 to 2022, including their pharmacokinetic and pharmacodynamic profiles and in-vitro and in-vivo assessments, is the main goal of this review. Considering the many stages these drugs are going through in their clinical trials, this investigation is especially pertinent. It should be noted that synthetic strategies are not discussed in this review; instead, they will be in a future publication.
