RESUMO

Medicinal plants with active ingredients have shown great potential as natural and sustainable additives in livestock and poultry diets as growth promoters, performance, feed conversion ratio, digestibility of nutrient enhancers, and antioxidants and immune system modulators. Among active ingredients, phytosterols, which are plant-based bio-factors that may be found in seeds, fruits, grains, vegetables and legumes, are thought to be involved in the aforementioned activities but are also widely known in human medicine due to their efficacy in treating diabetes, coronary heart disease, and tumors. Nevertheless, phytosterols can also promote carcinogens production, angiogenesis inhibition, metastasis, infiltration, and cancer cells proliferation. This review focuses on the deepening of the biological role and health benefits of phytosterols and their new potential application in poultry and livestock nutrition.

RESUMO

The SARS-CoV-2 virus targets the antigen converting enzyme 2 (ACE2) receptor, thus resulting in elevated morbidity and an increased risk of severe and fatal COVID-19 infection in individuals with hypertension and diabetes mellitus. Objectives: This study aimed to identify the association between increased susceptibility and severity in order to evaluate their impact in hypertensive COVID-19 patients using in vitro and in silico models. Methods: We identified 80 miRNA binding sites on ACE2 (for different miRNAs) as well as various 30 SNPs in the miRNA binding sites of the 3' untranslated region (3' UTR) in the ACE2 gene using different online software and tools. From August 2020 to August 2021, a total of 200 nasopharyngeal/mouth swabs samples were collected from Multan, Pakistan. In order to quantify the cDNA of ACE2 and miR-3658 genes, we used Rotor Gene qRT-PCR on hypertensive patients with COVID-19 as well as healthy controls. Results: Interestingly, the binding site of miR-3658 corresponding to the 3' UTR of ACE2 featured three SNPs (rs1457913029, C>T; rs960535757, A>C, G; rs1423809569, C>T), and its genomic sequence featured a single SNP (rs1024225815, C>T) with the same nucleotide variation (rs1457913029, C>T) which potentially increases the severity of COVID-19. Similarly, three other SNPs (rs1557852115, C>G; rs770335293, A>G; rs1024225815, C>T) were also found on the first binding site positions of miR-3658. Our in vitro study found that ACE2 gene expression had an effect on miR-3658 in COVID-19 patients who also had hypertension. In both cases, our analysis demonstrated that the in silico model captured the same biological mechanisms as the in vitro system. Conclusion: The identified SNPs could represent potential informative signatures owing to their position in the splicing site of the ACE2 gene.

RESUMO

Since ancient times, the Cucurbitaceae family is used as a therapeutic option in human medicine. This family has around 130 genera and 800 species. Researchers have studied the various plants of this family including Lagenaria siceraria due to their medicinal potential. Various properties are beneficial for human health, that have been attributed to L. siceraria like antioxidant, hypolipidemic, diuretic, laxative, hepatoprotective, analgesic, antihypertensive, cardioprotective, central nervous system stimulant, anthelmintic, free radical scavenging, immunosuppressive, and adaptogenic. The fruit of this plant is commonly used as a vegetable that has a low-calorie value. The species possess a diverse set of biological compounds like flavonoids, sterols, saponins, and terpenoids. Vitamins, choline, flavonoids, minerals, proteins, terpenoids, and other phytochemicals are also found in the edible parts of this plant. Besides 17 different amino acids, many minerals are reported to be present in the seeds of L. siceraria. According to the USDA nutritional database per 100 g of L. siceraria contains 14 Kcal energy, 3.39 g carbohydrates, 0.62 g protein, 0.2 g fat, and 0.5 g fiber. L. siceraria performs a wide range of pharmacological and physiological actions. The literature reviewed from various sources including PubMed, Science Direct, Google scholar, etc. shows the remarkable potential to treat various human and animal illnesses due to its' potent bioactive chemicals. The key objective of this thorough analysis is to present a summary of the data about the beneficial and harmful effects of L. siceraria intake on human health, as well as in veterinary fields.

RESUMO

This review was focused on global data analysis and risk factors associated with morbidity and mortality of coronavirus disease 2019 from different countries, including Bangladesh, Brazil, China, Central Eastern Europe, Egypt, India, Iran, Pakistan, and South Asia, Africa, Turkey and UAE. Male showed higher confirmed and death cases compared to females in most of the countries. In addition, the case fatality ratio (CFR) for males was higher than for females. This gender variation in COVID-19 cases may be due to males' cultural activities, but similar variations in the number of COVID-19 affected males and females globally. Variations in the immune system can illustrate this divergent risk comparatively higher in males than females. The female immune system may have an edge to detect pathogens slightly earlier. In addition, women show comparatively higher innate and adaptive immune responses than men, which might be explained by the high density of immune-related genes in the X chromosome. Furthermore, SARS-CoV-2 viruses use angiotensin-converting enzyme 2 (ACE2) to enter the host cell, and men contain higher ACE2 than females. Therefore, males may be more vulnerable to COVID-19 than females. In addition, smoking habit also makes men susceptible to COVID-19. Considering the age-wise distribution, children and older adults were less infected than other age groups and the death rate. On the contrary, more death in the older group may be associated with less immune system function. In addition, most of these group have comorbidities like diabetes, high pressure, low lungs and kidney function, and other chronic diseases. Due to the substantial economic losses and the numerous infected people and deaths, research examining the features of the COVID-19 epidemic is essential to gain insight into mitigating its impact in the future and preparedness for any future epidemics.
