Abstract:

The Agrobacterium tumefaciens zinc uptake regulator (Zur) was shown to negatively regulate the zinc uptake genes znuABC, encoding a zinc transport system belonging to the ATP-binding cassette (ABC) transporter family, and zinT, which encodes a periplasmic zinc-binding protein. The expression of znuABC and zinT was inducible when cells were grown in medium containing a metal chelator (EDTA), and this induction was shown to be specific for zinc depletion. The expression of znuABC was reduced in response to increased zinc in a dose-dependent manner, and zinT had a less pronounced but similar pattern of zinc-regulated expression. The inactivation of zur led to constitutively high expression of znuABC and zinT. In addition, a zur mutant had an increased total zinc content compared to the WT NTL4 strain, whereas the inactivation of zinT caused a reduction in the total zinc content. The zinT gene is shown to play a dominant role and to be more important than znuA and znuB for A. tumefaciens survival under zinc deprivation. ZinT can function even when ZnuABC is inactivated. However, mutations in zur, znuA, znuB or zinT did not affect the virulence of A. tumefaciens.

Abstract:

ABSTRACT The pathways ensuring the efficient uptake of zinc are crucial for the ability of bacteria to multiply in the infected host. To better understand bacterial responses to zinc deficiency, we have investigated the role of the periplasmic protein ZinT in Salmonella enterica serovar Typhimurium. We have found that zinT expression is regulated by Zur and parallels that of ZnuA, the periplasmic component of the zinc transporter ZnuABC. Despite the fact that ZinT contributes to Salmonella growth in media containing little zinc, disruption of zinT does not significantly affect virulence in mice. The role of ZinT became clear using strains expressing a mutated form of ZnuA lacking a characteristic histidine-rich domain. In fact, Salmonella strains producing this modified form of ZnuA exhibited a ZinT-dependent capability to import zinc either in vitro or in infected mice, suggesting that ZinT and the histidine-rich region of ZnuA have redundant function. The hypothesis that ZinT and ZnuA cooperate in the process of zinc recruitment is supported by the observation that they form a stable binary complex in vitro. Although the presence of ZinT is not strictly required to ensure the functionality of the ZnuABC transporter, our data suggest that ZinT facilitates metal acquisition during severe zinc shortage.

Abstract:

ABSTRACTAgrobacterium tumefacienshas a cluster of genes (Atu3178, Atu3179, and Atu3180) encoding an ABC-type transporter, here namedtroA,troB, andtroC, respectively, which is shown here to be a zinc-specific uptake system. Reverse transcription (RT)-PCR analysis confirmed thattroA,troB, andtroCare cotranscribed, withtroCas the first gene of the operon. TheyciC(Atu3181) gene is transcribed in the opposite orientation to that of thetroCBAoperon and belongs to a metal-binding GTPase family. Expression oftroCBAandyciCwas inducible under zinc-limiting conditions and was controlled by the zinc uptake regulator, Zur. Compared to the wild type, the mutant strain lackingtroCwas hypersensitive to a metal chelator, EDTA, and the phenotype could be rescued by the addition of zinc, while the strain with a singleyciCmutation showed no phenotype. However,yciCwas important for survival under zinc limitation when eithertroCorzinTwas inactivated. The periplasmic zinc-binding protein, ZinT, could not function when TroC was inactivated, suggesting that ZinT may interact with TroCBA in zinc uptake. Unlike many other bacteria, the ABC-type transporter ZnuABC was not the major zinc uptake system inA. tumefaciens. However, the important role ofA. tumefaciensZnuABC was revealed when TroCBA was impaired. The strain containing double mutations in theznuAandtroCgenes exhibited a growth defect in minimal medium.A. tumefaciensrequires cooperation of zinc uptake systems and zinc chaperones, including TroCBA, ZnuABC, ZinT, and YciC, for survival under a wide range of zinc-limiting conditions.IMPORTANCEBoth host and pathogen battle over access to essential metals, including zinc. In low-zinc environments, physiological responses that make it possible to acquire enough zinc are important for bacterial survival and could determine the outcome of host-pathogen interactions.A. tumefacienswas found to operate a novel pathway for zinc uptake in which ZinT functions in concert with the high-affinity zinc importer TroCBA.

Abstract:

Background In children, most idiopathic nephrotic syndrome (NS) is a minimal lesion, which responds well to steroids. Hyperhomocysteinemia is pathologic and worsens NS by causing chronic inflammation, leading to glomerular sclerosis. Zinc metalloenzymes are involved in homocysteine metabolism. Objective To assess for a possible relationship between serum zinc and homocysteine in children with NS. Methods A cross-sectional study was conducted in children with NS aged 1-18 years, who were admitted to Hasan Sadikin Hospital from November 2017 - January 2018. Subjects were selected consecutively. Serum zinc and homocysteine were measured in all subjects. Statistical analysis was done with Pearson’s correlation test. If the distribution was not linear, the analysis was continued with non-linear regression. Results There were 23 children who met the inclusion criteria. Mean serum homocysteine and zinc levels were 10.37 (SD 4.11) µmol/L and 51.13 (SD 29.69) µg/dL, respectively. Pearson’s correlation analysis showed no linear correlation between them (r coefficient -0.173; P=0.430). However, after adjusting for age and serum albumin level, multiple regression analysis suggested a cubical relationship between serum homocysteine and zinc, using the equation: homocysteine = -4.572 + 0.735 x zinc - 0.0012 x zinc2 + 0.00005 x zinc3 x age (months) (R2 multiple=53.2%; P=0.012). This equation indicates that 53.2% of homocysteine variation was influenced by serum zinc concentration. Conclusion In childhood NS, homocysteine is not correlated linearly with zinc, but related with cubical model.

Abstract:

Objective: Investigate the correlation between dietary intake of zinc, preeclampsia and blood zinc levels. Methods: This study, which compared pregnant women in the third trimester at the Wahidin Sudirohusodo Hospital and the educational network hospital with and without preeclampsia, used a Cross Sectional methodology. Zinc level testing was carried out at Prodia using ICP-MS method. Mann Whitney, Kruskal Wallis, and chi square tests were used to examine the data. Results: Preeclampsia group (n=38) and control group (n=40) were two groups made up of a total of 78 pregnant women. Zn level of severe preeclampsia (47.73 ± 11.23 ng/mL) was lower than preeclampsia (50.50 ± 13.59 ng/mL) and non-preeclampsia (50.58 ± 10.12ng/mL), but not significantly. Lower zinc rich-food consumption was a significant effect on zinc deficiency (p< 0.05), and was no significant effect on preeclampsia (p > 0.05). Conclusion: Low intake of zinc-rich foods and occasionally exposure to cigarette smoke are the causes of zinc insufficiency in third trimester pregnancy, but has little impact on the occurrence of preeclampsia.

Abstract:

A field experiment was conducted to study the efficiency of different sources of zinc in sorghum-wheat crop rotation on calcareous vertisol of Parbhani. Zinc application 4kg Zn/ha through zincated superphosphate proved its superiority over other zine sources in producing grain and fodder yield of sorghum. Among the zine snurces, the residual effect of zincated superphosphate was significantly higher in producing grain and straw yield of wheat followed by farm yard manure and zinc sulphate. Zinc application @ 4kg Za/ha through different Zinc sources significantly increased uptake of Zn.N and P by wheat crop. Highest uptake of nutrients was recorded with zincated superphosphate in both the crop.

Abstract:

Distribution of different forms of zinc in seven profiles of base unsaturated soils of Karnataka and their relation to soil characters were studied. The results showed that more than 82.7 per cent of total zinc occurred as residual zinc, whereas exchangeable zine occurred only 1.1 per cent of total zine content. Soils contained exchangeable Zn from 0.04 to 2.3 µg g', organically bound Zn from 0.07 to 6.44 ug g', manganese oxide bound from 0.1 to 4.3 ug gl amorphous iron oxide bound Zn from 0.5 to 7.7 Hg g, crystalline iron oxide bound from 0.5 to 8.2 µg g', residual zinc from 9 to 109 ug g'. Although the exchangeable pool was very low in all the soils when compared to other fractions, still it is very important from the plant availability point of view. Amorphous iron oxide bound form of zinc is the seat for zinc adsorption because of its high specific surface area. Crystalline iron oxide bound form of zinc dominated when compared to exchangeable, organically bound, manganese oxide bound and amorphous iron oxide bound zinc fractions.

Abstract:

Zinc is a nutrient that affects cell growth, helps the body's metabolism, activates T cells (T lymphocytes), cell regeneration, and repairs body tissues. Zinc in the body undergoes a process of excretion every day, therefore daily intake of zinc needs to be considered to maintain the amount of zinc in the body in a normal amount. This study aimed to obtain information on the application of the Inductively coupled plasma-mass spectrometry (ICP-MS) method to determine the concentration of zinc in the serum of pregnant women. The application of Inductively coupled plasma-mass spectrometry (ICP-MS) method in zinc analysis provided the advantages of a minimal sample volume requirement with higher instrument sensitivity, fast retention time and had a concentration detection limit of up to parts per billion (ppb). Analysis of the zinc concentration in the serum of pregnant women using the ICP-MS method showed 80% serum with a concentration below the reference value, 13.3% normal and 6.7% a concentration higher than the WHO reference value.Keywords: defisiensi zink, inductively coupled plasma-mass spectrometry (icp-ms), zinkABSTRAKAplikasi Metode Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) Dalam Analisis ZinkZink adalah salah satu jenis zat gizi yang sangat berpengaruh terhadap pertumbuhan sel, mengaktifkan sel T (limfosit T), regenerasi sel, dan membantu metabolisme tubuh.

Abstract:

Zinc is a micromineral present in the body tissues and fluids. Zinc is absorbed from the duodenum and stored in the form of metallothionine in the liver and excreted through sweat. Zinc plays a vital role in protein biosynthesis, gene expression; it also acts as an antioxidant and is used in the growth of the fungus. Due to the deficiency of zinc, a patient will be suffering from poor wound healing, lesions of skin, impaired spermatogenesis, hyperkeratosis, dermatitis and alopecia.An unprecedented COVID-19 pandemic caused by a novel corona virus called SARS-CoV-2, produces severe acute respiratory distress syndrome (ARDS). Zinc is used to treat COVID 19 because it improves the immunity. As the COVID patients are susceptible to zinc deficiency, they are prescribed with zinc supplements. Intake of zinc more than1000mg/day causes Zinc toxicity. Fungus utilises zinc for its growth. Mucormycosis caused by fungus Rhizopus species seen in most of the post COVID patients. Since, Zinc has assumed importance in this COVID 19 pandemic, this review article unfathoms the explicit roles of Zinc in humans.

Zinc adsorption in sixteen surface soil samples of Vertisol and Inceptisol was studied over a wide range of zinc solution concentrations (2.5 to 200 ppm). The zinc adsorption data conformed to Freundlich equation for the entire range of concentration tested. The Freundlich constants 'k' and 'n' were derived for zinc in these soils. The 'k' values ranged from 0.28 to 1.78 mg Zn/g with a mean value of 0.83 mg Zn/g soil. The 'k' values were significantly related to clay, CEC, silt, ex. calcium and free CaCO3. Multiple regression analysis revealed that zine adsorption can be predicted with good precisions from the above soil properties.

Abstract:

Crambe (Crambe abyssinica) é uma cultura promissora para a produção de biodiesel. No entanto, não há muita informação disponível sobre as técnicas e pesquisas sobre o melhor desempenho em diferentes regiões para explorar o seu potencial. Objetivou-se avaliar o efeito de cobre e zinco no acúmulo e distribuição destes elementos nesta planta. O estudo foi realizado em casa de vegetação e constou de dois experimentos independentes, em delineamento experimental inteiramente casualizado, com três repetições. Em um deles, os tratamentos consistiram em cinco doses de cobre, ou seja, 0, 10, 15, 20 e 25 mg kg-1 e no outro , cinco doses de zinco, 0, 20, 30, 40 e 50 mg kg-1. Após 100 dias de germinação as plantas foram colhidas e avaliadas os níveis de cobre e zinco em tecidos de plantas. Os dados foram submetidos à análise de variância e comparação de médias pelo teste de Tukey a 1 e 5% de significância. Os teores de cobre e zinco aumentaram significativamente na fitomassa do crambe em função da aplicação destes elementos no solo. Os acúmulos de cobre e zinco nas plantas de crambe obedeceram às seguintes ordens, respectivamente: raiz > parte aérea; parte aérea > raiz. O índice de translocação do zinco foi maior que a do cobre nas plantas de crambe.Content and translocation of copper and zinc in plant Crambe abyssinicaAbstract: Crambe is a promising crop for biodiesel production. However, there is no much information available about techniques and research regarding the best performance in different regions to explore its potential. The objective of this study was to evaluate the effect of copper and zinc in the accumulation and distribution of these elements in this plant. The study was carried out in a greenhouse and it consisted of two independent experiments in completely randomized design, with three replications. Two metals with five levels were applied: 0, 10, 15, 20 and 25 mg∙kg−1 for copper and 0, 20, 30, 40 and 50 mg∙kg−1 for zinc. After 100 days of germination the plants were harvested and assessed the levels of copper and zinc in plant tissues. Data were subjected to analysis of variance and comparison of means by Tukey test at 1 and 5% significance. Copper and zinc content increased significantly in the biomass of crambe due to the application of these elements in the soil. Copper and zinc accumulation in crambe plants followed the following orders, respectively: root> shoot; shoot> root. The zinc translocation ratio was higher than that of copper in crambe plants.

Abstract:

Introduction: Zinc is a vital trace element, which regulates metabolism of a prostate gland. It has been established that a low plasma zinc level in men increases the risk of chronic prostatitis and vice versa, chronic prostatitis is often accompanied by zinc deficiency in the prostate gland. The purpose of this study is to research the features and possible correlations of zinc metabolism disorders at systemic (in blood) and local (in prostatic fluid) levels in healthy men and patients with chronic bacterial prostatitis (CBP). Materials and methods: Ninety patients with CBP (main group) and thirty healthy men (control group) were randomized by age (mean age 38.5±2.9 years) and examined. In addition to standard examinations, the zinc levels in blood serum and prostatic fluid were determined, and the oxidative status of the prostate gland was assessed (the level of reactive oxygen species (ROS), conjugated dienes, malondialdehyde, superoxide dismutase (SOD) activity in the prostatic fluid) according to standard methods. Results and discussion: In patients with CBP, the absolute deficiency of plasma and prostatic zinc was detected 2.89 and 2.5 times more often, respectively, than in healthy men (p < 0.05). At the same time, both the patients with CBP and healthy men had significant correlations between plasma zinc and zinc in prostatic fluid (r = 0.345; n = 37; p = 0.001 and r = 0.156; n = 30; p = 0.001; respectively). A significant positive correlation between the zinc level and the activity of SOD in prostatic fluid was revealed only in the patients with CBP (r = 0.389; n = 90; p = 0.001). Conclusion: Zinc concentration in blood plasma does not objectively reflect zinc metabolism disorders in the prostate gland, and therefore the determination of zinc in prostatic fluid is the most reliable and sensitive method for assessing zink disorders in patients with CBP.

Abstract:

ABSTRACT An R-plasmid-mediated metallo-β-lactamase was found inKlebsiella pneumoniae DK4 isolated in Japan in 1991. The nucleotide sequence of its structural gene revealed that the β-lactamase termed DK4 was identical to the IMP-1 metallo-β-lactamase which was mediated by a chromosomal gene ofSerratia marcescens TN9106 isolated in Japan in 1991 (E. Osano et al., Antimicrob. Agents Chemother. 38:71–78, 1994). The dose effect of DK4 β-lactamase production on the resistance levels indicated a significant contribution of the enzyme to bacterial resistance to all the β-lactams except monobactams. The enzymatic characteristics of the DK4 β-lactamase and its kinetic parameters for nine β-lactams were examined. The DK4 β-lactamase was confirmed to contain 2 mol of zinc per mol of enzyme protein. The apoenzyme that lacked the two zincs was structurally unstable, and the activities of only 30% of the apoenzyme molecules could be restored by the addition of 1 mM zinc sulfate. The substitution of five conserved histidines (His28, His86, His88, His149, His210) and a cysteine (Cys168) for an alanine indicated that His86, His88, and His149 served as ligands to one of the zincs and that Cys168 played a role as a ligand to the second zinc. Both zinc molecules contribute to the enzymatic process. Mutant enzymes that lack only one of these retained some activity. Additionally, a conserved aspartic acid at position 90 was replaced by asparagine. This mutant enzyme showed an approximately 1,000 times lower k cat value for cephalothin than that of the wild-type enzyme but retained the two zincs even after dialysis against zinc-free buffer. The observed effect of pH on the activity suggested that Asp90 functions as a general base in the enzymatic process.

Abstract:

Zinc fortification is considered a potentially useful strategy for the control of zinc deficiency, but the success of such intervention programs depends on the population’s access to and consumption of zinc-fortified foods and adequate absorption of zinc from these foods. The latter issue has been assessed by a variety of studies that applied zinc isotopic tracers to assess zinc uptake from zinc-fortified foods. These studies show that the additional zinc provided by zinc fortification decreases fractional absorption of zinc, but increases total zinc absorption from these foods. Available studies show no significant difference in zinc absorption from foods fortified with either zinc oxide or zinc sulfate, which are the two cheapest chemical forms of zinc that are generally recognized as safe for human consumption. It appears that high-phytate meals depress zinc absorption from zinc-fortified foods, although total zinc absorption from such foods is still likely to be greater than if the foods were not fortified with zinc. With the possible exception of Na2EDTA, putative enhancers of zinc absorption do not seem to confer major benefits for zinc absorption from zinc-fortified foods. There is little information on the effect of fortification with other micronutrients on zinc absorption from co-fortified foods, and zinc fortification does not seem to suppress iron absorption from iron-fortified foods in most studies.

Abstract:

Os aços galvanizados são utilizados em grande número, principalmente nas indústrias automotivas, pela sua resistência à corrosão e baixo custo. A soldagem destes materiais, neste setor industrial, normalmente é realizada através do processo de soldagem a ponto. Em função dos aços galvanizados apresentarem uma camada de cobertura à base de zinco, normalmente utiliza-se durante soldagem, uma técnica denominada burn zinc (queima do zinco), para minimizar os efeitos prejudiciais do zinco neste material, durante o ciclo de soldagem. Neste contexto, este trabalho estudou um método não destrutivo, com o objetivo de encontrar uma adequada remoção desta camada de zinco, considerando para isto, os sinais gerados por um sensor que registra o deslocamento do eletrodo durante as fases do processo de solda a ponto, utilizando como base a leitura da expansão térmica da chapa de aço galvanizado. Assim, experimentos de simulação física foram feitos, variando a corrente e o tempo de ciclo da fase de preaquecimento. As respostas de burn zinc geradas pelo sensor e as análises visuais por atributo, foram mostradas em gráficos através de um envelope operacional. Evidências mostraram que o sinal de deslocamento do eletrodo, mostrou ser um eficiente método não destrutivo para a determinação de parâmetros adequados de burn zinc no processo de solda a ponto para chapas de aço galvanizadas.

Abstract:

Unlike iron, zinc absorption is influenced by dietary zinc intake, not zinc status. As dietary zinc increases, the total amount of absorbed zinc increases while the percent absorbed declines. The gastrointestinal tract maintains whole-body zinc homeostasis by adjusting endogenous zinc losses to the amount absorbed. At intakes below about 9 mg/day, zinc absorption occurs primarily by a saturable (carrier) process involving ZIP4, ZnT1, and other transporters. There is no evidence that past zinc intakes, or status, influences zinc absorption. Instead, current zinc intake is the chief determinant of zinc absorption. Supplemental zinc taken with water in the post-absorptive state initially is absorbed more efficiently than food zinc, but absorption efficiency declines within 24 hours presumably due to down-regulation of the zinc transporters. More research is needed to understand the effect of physiological state on zinc absorption.

Foram revisados 14 estudos de delineamento observacional. Dos estudos tipo coorte (dois), um indicou associação estatística entre o estado nutricional de ferro e o déficit de estatura; o outro apontou associação estatística entre as concentrações de ferritina sérica e o ganho de estatura. Dez estudos transversais investigaram a associação estatística entre as deficiências de micronutrientes e o déficit de estatura, resultando três deles na associação para o ferro, dois para a vitamina A e nenhum para o zinco. O esclarecimento sobre a associação entre o déficit de estatura e as deficiências de ferro, vitamina A e zinco dificulta-se por fatores de caráter biológico e relacionados à magnitude das deficiências, o que sugere a importância da padronização metodológica dos estudos.

<div>¿Qué tienen en común una pintura de Van Gogh, el latón, el galvanizado de metales, el ántrax y el proceso de digestión dentro de nuestro organismo? Aunque sin aparente relación, todo esto tiene en común al zinc. Este metal blanquecino es un elemento indispensable para un gran número de procesos biológicos, además de jugar un papel industrial muy importante (Emsley, 1998). La versatilidad de usos del zinc se debe a su relativa abundancia en nuestro planeta, así como a su estabilidad tanto en el estado natural (es decir zinc metálico) como en su estado de oxidación dos. Los yacimientos más importantes de zinc se encuentran en Norteamérica, principalmente en Canadá, seguidos de la antigua Unión Soviética, Australia, Perú y China.</div><div> </div>
