The sowing date is an important factor for expanding the cultivated area of rapeseed and affects seed yield, oil content, and fatty acid compounds. Micronutrient elements play an important role in improving the vegetative and reproductive growth of the plant, especially under conditions of biological and environmental stresses. A two-year experiment (2014-2016) was performed to study the response of rapeseed genotypes to foliar application of micronutrients on different sowing dates. The treatments were arranged as a factorial-split plot in a randomized complete block design with three replicates. Three sowing dates of 7 (well-timed sowing date), 17, and 27 (delayed sowing dates) October and two levels of foliar application with pure water (control), selenium (1.5%), zinc (1.5%), and selenium+zinc (1.5%) were factorial in the main plots and five genotypes of SW102, Ahmadi, GKH2624, GK-Gabriella, and Okapi were randomized in the subplots (a total of 30 treatments). Seed yield, oil yield and content, oleic acid, and linoleic acid were reduced when rapeseeds were cultivated on 17 and 27 October, while the contents in palmitic, linolenic, and erucic acids, and glucosinolate increased (p < 0.01). a selenium+zinc treatment improved seed yield, oil content and yield (p < 0.01). The oil quality increased due to increased contents of oleic and linoleic acids under the selenium+zinc treatment (p < 0.01). The GK-Gabriella and GKH2624 genotypes are recommended to be sown on well-timed (7 October) and delayed sowing dates (17 and 27 October) and treated with selenium+zinc due to the higher oil yield, linoleic and oleic acids.

According to World Health Organization (WHO) approximately four million children less than 5 years of age in Asia, Africa, and Latin America die annually from diarrhea; and 80% of these deaths occur in the first year of life. Objective: To see how a zinc supplement influences the severity of acute diarrhea in children under the age of five. Methods: In current study, we analyze the effect of zinc on diarrheal patients. Zinc was randomly assigned to diarrheal patients in different concentration 5 mg, 10 mg, 15 mg and 20 mg. There were two groups in our study, treatment and control group. Results: The results are presented in the form of descriptive and inferential statistics. In T1 (Treatment Group) number of Diarrhea patients < 1 Year of age were 16, 2-4 years of age were 45, 4-5 years of age and maximum no of patients in T1 < 2 year of age were 57. Number of male patients were 84 while female patients were 67 in T1.In T2 (Control Group) number of male patients were 92 while female patients were In T1 number of patients residing in urban area were 51 while rural were 100. In T2 number of urban were 69 while rural were 82.Number of patients stay in the hospital for one day were 67 ,15 for Four days and only 1 for seven days in T1. In T2 number of patients stay in the hospital for one day were 29, 17 for four days and only 6 for seven days. In T1 number of Patients with watery diarrhea were 87, Mucoid consistency of stool were 31,soft consistency of stool were 23 and formed consistency of stool were 9.In T2 watery diarrhea were 92,Mucoid consistency of stool were 25,soft consistency of stool were 31 and formed consistency of stool were 4. Frequency of stool significantly reduced (P<0.005) at 7th day of zinc treatment while consistency of stool was significantly improved (P<0.005) at day 3 and day 5 of zinc treatment. Children who received zinc supplements showed a marked improvement in all outcome measures, suggesting that this deficiency is amenable to correction by replacement.

In diabetic patients, medial vascular calcification is common and associated with increased cardiovascular mortality. Excessive glucose concentrations can activate the nuclear factor kappa-light-chain-enhancer of activated B-cells (NF-kB) and trigger pro-calcific effects in vascular smooth muscle cells (VSMCs), which may actively augment vascular calcification. Zinc is able to mitigate phosphate-induced VSMC calcification. Reduced serum zinc levels have been reported in diabetes mellitus. Therefore, in this study the effects of zinc supplementation were investigated in primary human aortic VSMCs exposed to excessive glucose concentrations. Zinc treatment was found to abrogate the stimulating effects of high glucose on VSMC calcification. Furthermore, zinc was found to blunt the increased expression of osteogenic and chondrogenic markers in high glucose-treated VSMCs. High glucose exposure was shown to activate NF-kB in VSMCs, an effect that was blunted by additional zinc treatment. Zinc was further found to increase the expression of TNFα-induced protein 3 (TNFAIP3) in high glucose-treated VSMCs. The silencing of TNFAIP3 was shown to abolish the protective effects of zinc on high glucose-induced NF-kB-dependent transcriptional activation, osteogenic marker expression, and the calcification of VSMCs. Silencing of the zinc-sensing receptor G protein-coupled receptor 39 (GPR39) was shown to abolish zinc-induced TNFAIP3 expression and the effects of zinc on high glucose-induced osteogenic marker expression. These observations indicate that zinc may be a protective factor during vascular calcification in hyperglycemic conditions.

Although there have been reported associations between zinc and bone mineral density (BMD), no reports exist on the effect of zinc treatment in osteoporotic patients. Therefore, we investigated the efficacy and safety of zinc pharmacotherapy in Japanese elderly patients. The present investigation included 122 osteoporotic patients with zinc deficiency, aged ≥65 years, who completed 12 months of follow-up. In addition to standard therapy for osteoporosis in a clinical setting, the subjects received oral administration of 25 mg zinc (NOBELZIN®, an only approved drug for zinc deficiency in Japan) twice a day. BMD and laboratory data including bone turnover markers were collected at 0 (baseline), 6, and 12 months of zinc treatment. Neither serious adverse effects nor incident fractures were seen during the observation period. Serum zinc levels were successfully elevated by zinc administration. BMD increased significantly from baseline at 6 and 12 months of zinc treatment. Percentage changes of serum zinc showed significantly positive associations with those of BMD. Bone formation markers rose markedly from the baseline values, whereas bone resorption markers displayed moderate or no characteristic changes. Additive zinc supplementation may contribute to BMD augmentation ensuing the prevention of fracture occurrence in elderly osteoporotic patients with zinc deficiency.

A review of modern scientific publications in the field of methods for preparing the surface of aluminum alloys for electroplating is presented. It is shown that the most widely used methods of preparation are: zinc treatment, high-porosity anodic oxidation and immersion nickel plating. A number of combined methods for preparing the surface of aluminum alloys for electroplating are given. Methods of direct application of electroplating coatings on aluminum and its alloys without the use of a sublayer, both by electrolytic and chemical methods, are considered.

Angiogenesis is a precise process mediated by a variety of signals and the environmental niche. Although the essential trace element zinc and its homeostasis are essential for maintaining proper cellular functions, whether zinc plays a role in angiogenesis is currently unknown. Using zebrafish embryos as a model system, we found that zinc treatment significantly increased the expression of the slc39a5 gene, which encodes the zinc transporter Slc39a5. Moreover, knocking down slc39a5 expression using either a morpholino or CRISPR/Cas9-mediated gene editing led to cardiac ischaemia and an accumulation of red blood cells in the caudal vein plexus (CVP), as well as delayed venous sprouting and fewer vascular loops in the CVP region during early development. Further analysis revealed significantly reduced proliferation and delayed cell migration in the caudal vein of slc39a5 morphants. At the mechanistic level, we found increased levels of systemic zinc in slc39a5 -deficient embryos, and chelating zinc restored CVP development. In addition, we found that zinc overload in wild-type embryos leads to impaired CVP formation. Taken together, these results indicate that Slc39a5 plays a critical role in endothelial sprouting and migration in venous angiogenesis by regulating zinc homeostasis.

Abstract The clinical data of safety and efficacy of a combined treatment with dimercaptosuccinic acid (DMSA) and Zinc with 2 years’ follow-up in 60 neurological Wilson’s disease (WD) patients was retrospectively analyzed. All the patients included in the present study were newly diagnosed and initialized with D-penicillamine (DPA) treatment but were found to have either neurological deterioration or allergy, and their treatment was switched to a combined treatment of DMSA and Zinc. Fifty-one patients (85%) had the neurological symptoms improved 1 and 2 years after treatment, 7 (11.67%) experienced a stable neurological condition, and 2 (3.33%) suffered deterioration of neurological symptoms. No early neurological deterioration was observed in all patients. Twenty-five percent patients experienced mild adverse reactions which did not require a discontinuation of the DMSA and Zinc treatment. Our study confirmed the safety and efficacy of the combined DMSA and Zinc therapy as an initial and probably long-term treatment in neurological WD patients.
