Abstract: The world experienced the outbreak of a new pandemic disease in 2019, known as coronavirus (CoV) disease 2019 (COVID-19), which is caused by the novel severe acute respiratory syndrome-CoV-2 (SARS-CoV-2). The respiratory system is the organ system most commonly affected by COVID-19 however, several other organ systems have been reported to be affected. The SARS-CoV-2 RNA found in infected stub s les can cause lung contagion by binding to the angiotensin-converting enzyme-2 (ACE-2) receptor of the alveolar epithelial cells. The gut microbiota (GM) promote immunity, indicating that the alignment of the microbiota and corresponding metabolic processes in COVID-19 can help to identify novel biomarkers and new therapeutic targets for this disease. The cause of kidney damage in COVID-19 patients is possibly multifactorial, involving a complex mechanism that involves complement dysregulation and thrombotic microangiopathy, as well as the occurrence of a “cytokine storm” syndrome, which are immune responses that are abandoned and dysfunctional with unfavorable prognosis in severe COVID-19 cases. Furthermore, COVID-19 involves a continuous proliferation and activation of macrophages and lymphocytes. SARS-CoV-2 can also bind to the ACE-2 receptor expressed in the cerebral capillary endothelial cells that can invade the blood-brain wall, to penetrate the brain parenchyma. However, in the ongoing pandemic, there has been a surge in studies on a wide range of topics, including causes of respiratory failure, asymptomatic patients, intensive care patients, and survivors. This review briefly describes the damaging effects of COVID-19 on vital human organs and the inhibitory function of the ACE-2 receptor on the GM, which causes gut dysbiosis, and thus, this review discusses topics that have an opportunity for further investigation.

Abstract: The critical limit for zinc (Zn) varies from 0.38 to 2 µg/g soil depending on the crop and soil type. However, the critical limit for Zn was not explored recently for rice and potato cultivation in the floodplain soils of Bangladesh. A pot experiment was conducted to determine the critical limits of Zn in soil and plants for rice and potato cultivation in two agro-ecological zones (AEZs) of Bangladesh. The soil s les were collected from 20 different locations of Old Brahmaputra and Active Ganges Floodplains with low ( .9 µg/g), medium (0.91–1.80 µg/g) and high ( .80 µg/g) Zn status. The experiment was laid out in a factorial and completely randomized design with two levels of Zn (Zn0 and Zn1 (0 and 4.87 kg/ha as Zn sulphate)) applied to 20 different soil s les for rice and potato cultivation using three replications. The critical limit of Zn was determined through a graphical and statistical approach and crops were harvested at the stem elongation (for rice) and tuber filling (for potato) stage. The critical limit of Zn in soil for rice was found to be 0.8 and 0.85 µg/g by graphical and statistical methods, respectively, and both methods revealed the same value (0.73 µg/g) for potato. The critical limit of Zn in rice plants was 23.9 and 24.32 µg/g, whereas in potato plants it was 27.1 and 26.61 µg/g, determined by graphical and statistical methods, respectively. The added Zn supply in soil significantly increased the dry matter accumulation in rice (by 5.6%) and potato (by 10%) compared to no Zn supply. Therefore, a significant positive response to added Zn could be observed on crop growth and yield when the Zn concentration remained below the mentioned critical level for rice and potato cultivation in floodplain soils of Bangladesh.

Abstract: Background/Objectives: Moringa (Moringa oleifera) is a multi-purpose tree with valuable nutritional density found in the leaves and pods. Both seasonal and year-round cultivars are available and consumed in Bangladesh. This study evaluated the qualitative and quantitative morphological characteristics and nutritional content in leaves and pods of moringa cultivars from two major ecological locations in Bangladesh. Methodology: The selected local varieties used were seasonal production (SP: V1) and year-round production (YP: V2) cultivars from the two ecological regions Chapai Nawabganj (L1) and Pabna (L2). Findings: Flowering and fruiting occurred once per year in seasonal cultivar (SP) and three times per year in year-round cultivar (YP). Flowers are zygomorphic and tripinnate and pinnately compound leaves in both cultivars. The average yield of pods over two years of production for V1 was 45-62 kg/year lant and 27-38 kg lant/year for V2. Leaves contained more than two times higher protein (29-36%) compared to pods (11-15%). Similarly, nutrients including calcium and iron were significantly higher in leaves (2314-3487 ppm and 276-418 ppm, respectively) than pods (2017-2032 ppm and 61-68 ppm, respectively). There were no significant differences in potassium content of both cultivars in both location, but pod contained more than four times higher phosphorus (1.5- 1.7%) than leaves (0.34-0.38%). The highest amounts of magnesium (1768-1861 ppm) and sodium (496-535 ppm) were found in pods. Applications: Cultivar and plant part (e.g leaves) can be considered when promoting and utilizing moringa micronutrient for nutritional security. It demands for policies and development actions for production and intensification of moringa in dry parts of the country. Keywords: Moringa cultivars leaves pods morphology nutritional security
