IntroductionUndernutrition is a major risk factor for tuberculosis (TB), which is estimated to be responsible for 1.9 million TB cases per year globally. The effectiveness of micronutrient supplementation on TB treatment outcomes and its prognostic markers (sputum conversion, serum zinc, retinol and haemoglobin levels) has been poorly understood. This study aimed to determine the effect of zinc and vitamin A supplementation on prognostic markers and TB treatment outcomes among adults with sputum-positive pulmonary TB.MethodsA systematic literature search for randomised controlled trials (RCTs) was performed in PubMed, Embase and Scopus databases. Meta-analysis with a random effect model was performed to estimate risk ratio (RR) and mean difference (MD), with a 95% CI, for dichotomous and continuous outcomes, respectively.ResultsOur search identified 2195 records. Of these, nine RCTs consisting of 1375 participants were included in the final analyses. Among adults with pulmonary TB, zinc (RR: 0.94, 95% CI: 0.86 to 1.03), vitamin A (RR: 0.90, 95% CI: 0.80 to 1.01) and combined zinc and vitamin A (RR: 0.98, 95% CI: 0.89 to 1.08) supplementation were not significantly associated with TB treatment success. Combined zinc and vitamin A supplementation was significantly associated with increased sputum smear conversion at 2 months (RR: 1.16, 95% CI: 1.03 to 1.32), serum zinc levels at 2 months (MD: 0.86 μmol/L, 95% CI: 0.14 to 1.57), serum retinol levels at 2 months (MD: 0.06 μmol/L, 95% CI: 0.04 to 0.08) and 6 months (MD: 0.12 μmol/L, 95% CI: 0.10 to 0.14) and serum haemoglobin level at 6 months (MD: 0.29 μg/dL, 95% CI: 0.08 to 0.51), among adults with pulmonary TB.ConclusionsProviding zinc and vitamin A supplementation to adults with sputum-positive pulmonary TB during treatment may increase early sputum smear conversion, serum zinc, retinol and haemoglobin levels. However, the use of zinc, vitamin A or both was not associated with TB treatment success.PROSPERO registration numberCRD42021248548.

Background:The abundance of transcripts arising fromMycobacterium tuberculosis(MTB) in sputum pre-chemotherapy may enhance our understanding of factors influencing treatment response. We hypothesized that differences in the prevalence of pre-existing slowly metabolizing MTB in sputum may be partially responsible for differences in the rate of sputum clearance during treatment.Methods:Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to characterize a selected limited transcription profile of MTB in sputum pre-chemotherapy and assess inter-individual variation. The difference in cycle threshold (Ct) per gene, normalized to 16S, between exponential/stationary phase culture and sputum was calculated and stratified by 2-month culture converter status.Results:HIV-1 uninfected patients with rifampicin-susceptible tuberculosis provided sputum pre-chemotherapy; 11 patients were negative for MTB culture after two months of therapy and 8 remained culture-positive.Increasedicl1andprpDandrpsN2:rpsN1in sputum relative to culture suggested cholesterol utilization and a low-zinc environment respectively. IncreasedhspXand decreasedatpAandnuoGrelative to exponential culture suggested a slowly metabolizing subpopulation of MTB. While the thehspXhiatpAlonuoGlosignal varied, we did not observe statistically significant enrichment of this phenotype in the non-converter population nor an association with MTB-lineage.Conclusion:Differential abundance of selected informative transcripts suggested a metabolically less-active subpopulation with a prevalence that varied between individual untreated patients.

ABSTRACT Sputum and serum from patients with active pulmonary tuberculosis (TB), healthy purified protein derivative-positive adults, and patients with bacterial pneumonia were collected to simultaneously assess local immunity in the lungs and peripheral blood. To determine whether cytokine profiles in sputum from TB patients and control subjects were a reflection of its cellular composition, cytospin slides were prepared in parallel and assessed for the presence of relative proportions of epithelial cells, neutrophils, macrophages, and T cells. Gamma interferon (IFN-γ) in sputum from TB patients was markedly elevated over levels for both control groups. With anti-TB therapy, IFN-γ levels in sputum from TB patients decreased rapidly and by week 4 of treatment were comparable to those in sputum from controls. Further, IFN-γ levels in sputum closely followed mycobacterial clearance. Although detected at fourfold-lower levels, IFN-γ immunoreactivities in serum followed kinetics in sputum. TNF-α, interleukin 8 (IL-8) and IL-6 also were readily detected in sputum from TB patients at baseline and responded to anti-TB therapy. In contrast to IFN-γ, however, TNF-α and IL-8 levels also were elevated in sputum from pneumonia controls. These data indicate that sputum cytokines correlate with disease activity during active TB of the lung and may serve as potential early markers for sputum conversion and response to anti-TB therapy.

A previous study involving a proteomic screen of induced sputum from smokers and patients with chronic obstructive pulmonary disease (COPD) demonstrated elevated levels of bactericidal/permeability-increasing fold-containing protein B1 (BPIFB1). The aim of the present study was to further evaluate the association of sputum BPIFB1 levels with smoking and longitudinal changes in lung function in smokers with COPD. Sputum BPIFB1 was characterized by two-dimensional gel electrophoresis and mass spectrometry. The expression of BPIFB1 in COPD was investigated by immunoblotting and immunohistochemistry using sputum and lung tissue samples. BPIFB1 levels were also assessed in induced sputum from nonsmokers ( n = 31), smokers ( n = 169), and patients with COPD ( n = 52) via an ELISA-based method. The longitudinal changes in lung function during the 4-year follow-up period were compared with the baseline sputum BPIFB1 levels. In lung tissue samples, BPIFB1 was localized to regions of goblet cell metaplasia. Secreted and glycosylated BPIFB1 was significantly elevated in the sputum of patients with COPD compared with that of smokers and nonsmokers. Sputum BPIFB1 levels correlated with pack-years and lung function as measured by forced expiratory volume in 1 s (FEV1) % predicted and FEV1/FVC (forced vital capacity) at baseline and after the 4-year follow-up in all participants. The changes in lung function over 4 years were significantly associated with BPIFB1 levels in current smokers with COPD. In conclusion, higher sputum concentrations of BPIFB1 were associated with changes of lung function over time, especially in current smokers with COPD. BPIFB1 may be involved in the pathogenesis of smoking-related lung diseases.

Background: Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis, can affect almost all organs of the body with the most locations in the lungs. Immunity and high nutrients such as vitamin C, zinc and other antioxidants have shown good effects for infections, including tuberculosis. One effort to help accelerate sputum conversion of people with pulmonary tuberculosis is by supplementation of Zinc Sulphate and Omega 3.Objective: Analyze the role of Zinc Sulphate and Omega 3 on sputum conversion acceleration in patients with pulmonary tuberculosis at Surabaya Paru Hospital 2015.Method: This research use Randomized Pre Post Test Post Control Group Design design. In patients with pulmonary tuberculosis with Zinc Sulphate and Omega 3 in the treatment and placebo group in the control group. A sample of 20 patients consisting of 10 treatment patients and 10 control patients. Statistical test using paired T-Test, Friedman test and Mann whitney.Results: Friedman test showed that in the treatment group showed significant difference in the number of BTA between before and after supplementation (p=0,001), while in the control group significance of 0.141. Mann-Whitney test showed no significant difference in the amount of reduction of BTA between the treatment group and the control group (p = 0.080). This means that statistically does not show any significant difference.Conclusions: Zinc Sulphate and Omega 3 play a role in accelerating sputum smear conversion of respondents. The results of smear test in pulmonary TB patients with Zinc Sulphate and Omega 3 supplementation showed positive results

Forty-four patients with allergic (ABA) and non-allergic (NABA) variants of bronchial asthma (BA) were examined to evaluate levels of key adipokines (leptin, resistin, adiponectin) in sputum in different variants of BA. Adipokines in sputum and blood plasma were measured by Enzyme-Linked Immunosorbent Assay (ELISA). The indices that reflect the percentage of adipokines in sputum regarding adipokines in plasma of the same patients were worked out to evaluate the ratio of levels of corresponding adipokines in plasma and sputum in patients with BA. Two regularities are clearly seen in the study: the first - levels of proinflammatory adipokines (leptin, resistin) in sputum in ABA correlate directly with indicators of respiratory function but levels of anti-inflammatory adipokines (adiponectin) in sputum correlate inversely with indicators of respiratory function; the second -correlation of levels of the studied adipokines with indicators of respiratory function are almost not revealed in NABA. The first regularity reflects the important fact that the content of adipokines in bronchial secretion is to a certain extent one of regulating local mechanisms in target organ controlled system levels of corresponding adipokines in exacerbation of BA.

The main purpose of the work reported in this thesis was to investigate and characterise the deep levels in zinc selenide crystals grown from the vapour phase at Durham, and by the CVD technique at AWRE, Aldermaston. The methods of TSC, TSL and DLTS were applied to samples of Durham-grown and CVD ZnSe. The study revealed the presence of traps at 0.14-0.16,0.23, 0.26, 0.30-0.31, 0.45, -0.60 and 0.70 eV in Durham-grown material, whereas the CVD material was found to contain trapping levels at 0.10, 0.20 and 0.27-0.28 eV. The 0.10 eV level in CVD ZnSe is ascribed to the Na acceptor. The traps occurring at 0.26-0.31 eV in both materials are thought to be due to a vacancy-impurity complex. Examination of the CVD material using the EBIC technique in an SEM revealed that the conductivity was limited by electrically-active grain boundaries which were shown to obey a simple potential barrier model. Cathodoluminescence studies showed that the emission bands at 465 nm (edge emission) and 630 nm (copper-red) were quenched at the grain boundaries. A relationship between the absorption coefficient at 10.6 ym and the intensity of the copper-red emission was demonstrated, which has important implications in the production of low absorption zinc selenide for laseroptics.

Experiments were carried out to examine the value of CCS (copper chaperone for CuZn superoxide dismutase) as a novel biomarker of zinc-induced mild copper deficiency and to evaluate the changes in expression of zinc transporters in response to graded levels of moderately high dietary zinc. Weanling male Wistar rats were fed graded levels of zinc (30, 60, 120 and 240 mg zinc/kg diet) for 5 weeks. Results showed a dose-dependent decrease in copper content and an increase in CCS expression in tissues of rats fed the Zn-60 and Zn-120 diets. Surprisingly, rats fed the Zn-240 diet showed better copper status than rats fed the Zn-120 diet. Expression of zinc transporters was significantly upregulated in the small intestine of Zn-240 rats. Collectively, these data show that CCS is responsive to zinc-induced mild copper deficiency, and can serve as a sensitive biomarker of mild copper deficiency. The increased expression of intestinal zinc transporters expression may account for the better copper status of Zn-240 rats.

Heavy metal contamination in food is a worldwide concern. Man-made ponds are domestic sites in the production of Procambarus clarkii and Procambarus zonangulus, two edible species of crayfish. Ponds may be constructed in former sugar cane or rice fields. Crayfish farming is an ancillary seasonal business within the rice-growing season. The use of products to control insects, pests, and weeds in rice and sugar cane production, may cause an accumulation of heavy metals in the crayfish tail within pond structures. Arsenic, cadmium, copper, and zinc are heavy metals that are absorbed through the roots of and distributed through rice products. Metabolites associated with rice products are absorbed in the human body. Research suggests that metabolites associated with heavy metals cause disease in animals and humans.

High levels of Cu and Zn application to agricultural soils are considered to pose a potential hazard to plants and animals. The levels of Cu and Zn which can be safely added to cropland have yet to be established. This study was conducted on a Davidson silty clay (Rhodic Paleudult) to determine the response of corn (Zea mays L.) to cumulative application of up to 469 kg Cu and 1032 kg Zn ha⁻¹ as sulfates over the 22-year period from 1967 through 1988. Neither corn grain nor silage yield was affected by the metal additions even though the cumulative amount of Cu and Zn added exceeded the maximum allowable Cu and Zn loading rates based on the U.S. Environmental Protection Agency guidelines (i.e., 250 kg Cu and 560 kg Zn ha⁻¹) for this soil. The twenty-first annual application of Cu as CuSO₄, increased Cu concentrations in ear leaves. However, Cu concentrations in ear leaves were unaffected by the twenty-second year of Cu application. Concentrations of Zn in ear leaves were increased by the high level of Zn application during the two years of the study. Twenty-first year Cu and Zn concentrations in com grain were not increased by the high levels of Cu and Zn sulfates. All grain and ear leaf Cu and Zn concentrations were within the normal ranges from the high amount of metal application. The DTPA extractable Cu and Zn in the soil increased with an increase in level of applied Cu and Zn. More Cu and Zn were extracted from the soil by the Mehlich-3 method than by the DTPA method. This higher rate of extraction was attributed to the ethylenediaminetetraacetic acid (EDTA) in the Mehlich-3 solution.

Copper and Zn deficiencies of crop plants occur in various areas throughout the world. The sulfate forms of Cu and Zn are generally used to correct these micronutrient deficiencies. In agricultural practices, Cu and Zn are applied to soils not only as a fertilizer but also as manures, pesticides and waste materials such as sewage sludge. High levels of Cu and Zn application to agricultural soils are considered to pose a potential hazard to plants and animals. Research findings have not established Cu and Zn levels that either injure plants or increase Cu and Zn concentrations in edible plant portions to undesirably high levels. Published data on the fate of applied Cu and Zn indicate that there is little, if any, downward movement of these micronutrients in soils and that, with time, applied Cu and Zn revert to plant unavailable forms in soils.

Limited research has examined the effects that plant-based diets have on copper (Cu) and Zinc (Zn) absorption and utilization in rainbow trout. Few studies have been conducted to determine if interactions exist in the utilization of Cu when increasing levels of supplementary Zn were offered. The objectives of this research were to: first determine what effect protein source (plant vs. animal based), Cu source (complex vs. inorganic) and concentrations of Cu (0, 5, 10, 15, 20 ppm) in the diet had on rate and efficiency of gain and Cu tissue levels in rainbow trout. The second experiment was to determine if interactions occur due to increasing diet content of Zn (0, 30, 300, 1500 ppm) and Cu provided at two levels (0 or 10 ppm) on tissue levels of Cu in rainbow trout. From experiment one, trout fed plant-based diet had higher (P < 0.05) ADG and improved (P < 0.05) FCR in comparison to fishmeal fed trout. Highest (P < 0.05) hepatic Cu concentrations were also observed in trout fed plant-based diets. No differences (P >0.05) were observed in growth or hepatic concentrations due to Cu source. From experiment two, no antagonistic interactions were observed between increasing levels of dietary Zn and Cu. Trout fed the two highest levels of dietary Zn (300 and 1500 ppm) had the greatest (P < 0.05) weight gains. Dietary Zn supplementation increased (P < 0.05) whole body Cu at 12 wks. With increasing dietary Zn supplementation, resulted in increased (P < 0.05) whole body Zn. Cataracts and tail rot were observed at 12 wks in trout fed the Cu and Zn deficient diet. In conclusion, plant-based diets enhanced Cu bioavailability indicated by higher weight gains and hepatic Cu concentrations in experiment one, compared to trout fed fishmeal-based diets. Cu supplementation is required in a plant-based in order to achieve optimal growth in trout. Results of the second study indicate rainbow trout fed plant-based diets require Zn supplementation to obtain sufficient growth. The highest levels of Zn supplementation did not impair Cu uptake in rainbow trout.

It is hypothesized that exposing endothelial cells to steady or non-reversing pulsatile shear stress produces a healthy, anti-atherogenic endothelium, whereas a reversing pulsatile shear stress promotes an unhealthy, pro-atherogenic endothelium. To further investigate this hypothesis, a novel parallel plate flow chamber system was used to expose human endothelial cells to a pro-atherogenic reversing shear stress waveform designed to simulate the wall shear stress at the carotid sinus, a region prone to atherosclerosis. Cells exposed to this reversing shear stress were compared to cells exposed to high levels of steady shear stress (15 dynes/cm²), low steady shear stress (1 dyne/cm², the time-average of the carotid shear stress), and static culture conditions. Functional analysis confirmed previous findings that reversing shear stress increases cell proliferation and monocyte adhesion. Microarray results indicate that although there are unique sets of genes controlled by both low average shear stress and by reversing flow, more genes were controlled by low average shear stress. We propose that low-time average shear stress, and not fluid reversal/oscillation, may be the more significant mechanical force. The reversing shear stress system was also used to investigate two shear stress-responsive genes, CYP1A1 and CYP1B1. Both were maximally up-regulated at arterial steady shear stresses of at least 15 dynes/cm² and reversing pulsatile shear stress attenuated expression of both genes. Furthermore, AhR nuclear localization and CYP1A1 protein expression correlate with the flow patterns in the mouse aortic arch. The data strongly suggest that the AhR/CYP1 pathway promotes an anti-atherogenic phenotype in the endothelium. Changes in free zinc were measured under different shear stresses. High steady shear stress dramatically increases the levels of free zinc in endothelial cells as compared to cells grown in static culture. This increase in free zinc is attenuated under reversing shear stress and low steady shear stress, which correlates with an increase in zinc-binding metallothinein proteins and zinc exporter Znt-1. Overall, the findings provide further insight into endothelial responses to mechanical forces and may be important in understanding mechanisms of atherosclerotic development and localization to regions of disturbed flow.

The relevance of the research is due to the need to develop technologies for phytoremediation of the devastated lands in the mining and metallurgical regions of Ukraine and the world. In this regard, the creation of tree plantations adapted to the ecological conditions of such territories is considered by many experts as the most promising option for innovative technologies. However, the development of artificial woodlands requires knowledge of the pedogeochemical character- istics of devastated lands. The aim of the work was to carry out a comparative analysis of the macronutrients and heavy metals gross forms content in the soils of the devastated lands of the Kryvyi Rih mining and metallurgical region. The field studies focused on five contrasting monitoring sites of the Petrovsky dump (Central Kryvorizhzhya), which has a typical age and composition of rocks for the region. Soil sampling, drying, sieving, and sample preparation (sintering in a muffle furnace) were done in accordance with classical techniques. The concentrations of macronutrients (potassium, sodium, calcium, magnesium, sulfur, and phosphorus) and heavy metals (iron, manganese, zinc, copper, lead, and cadmium) were determined using an Inductively Coupled Plasma Mass Spectrometry (ICP- MS) X-Series 2 (Thermo Fisher Scientific, USA). The analytical part of our research was carried out on the basis of the laboratory of the Institute of Biosciences, Freiberg University of Technology and Mining Academy (Freiberg, Germany). At monitoring sites, significant differences were found in the content of macronutrients gross forms, and their variation relative to the control values as well. Potassium and sodium concentrations generally differed slightly or were close to control levels. The results of determining the content of calcium, magnesium and phosphorus indicate a significant deficiency or excess of these macronutrients in the soils of the devastated lands. An increased sulfur content was found in the soils of all monitoring sites, in some cases 4 times higher than the control level. The measured content of gross forms of iron, manganese, copper, cadmium and, partially, zinc in the soils of different monitoring sites exceeded the control values by 5.5 – 5.9 times. Thus, the analysis of the research results made it possible to establish that the soils of the devastated lands of the Petrovsky dump are characterized by unfavorable properties for the growth of most species of woody plants.

Citrus, like many other tropical and subtropical fruit are sensitive to chilling temperatures. However, application of a pre-storage temperature conditioning (CD) treatment at 16°C for 7 d or of a hot water brushing (HWB) treatment at 60°C for 20 sec remarkably enhances chilling tolerance and reduces the development of chilling injuries (CI) upon storage at 5°C. In the current research, we proposed to identify and characterize grapefruit genes that are induced by CD, and may contribute to the acquisition of fruit chilling tolerance, by two different molecular approaches: cDNA array analysis and PCR cDNA subtraction. In addition, following the recent development and commercialization of the new Affymetrix Citrus Genome Array, we further performed genome-wide transcript profiling analysis following exposure to CD and chilling treatments. To conduct the cDNA array analysis, we constructed cDNA libraries from the peel tissue of CD- and HWB-treated grapefruit, and performed an EST sequencing project including sequencing of 3,456 cDNAs from each library. Based on the obtained sequence information, we chose 70 stress-responsive and chilling-related genes and spotted them on nylon membranes. Following hybridization the constructed cDNA arrays with RNA probes from control and CD-treated fruit and detailed confirmations by RT-PCR analysis, we found that six genes: lipid-transfer protein, metallothionein-like protein, catalase, GTP-binding protein, Lea5, and stress-responsive zinc finger protein, showed higher transcript levels in flavedo of conditioned than in non-conditioned fruit stored at 5 ᵒC. The transcript levels of another four genes: galactinol synthase, ACC oxidase, temperature-induced lipocalin, and chilling-inducible oxygenase, increased only in control untreated fruit but not in chilling-tolerant CD-treated fruit. By PCR cDNA subtraction analysis we identified 17 new chilling-responsive and HWB- and CD-induced genes. Overall, characterization of the expression patterns of these genes as well as of 11 more stress-related genes by RNA gel blot hybridizations revealed that the HWB treatment activated mainly the expression of stress-related genes(HSP19-I, HSP19-II, dehydrin, universal stress protein, EIN2, 1,3;4-β-D-glucanase, and SOD), whereas the CD treatment activated mainly the expression of lipid modification enzymes, including fatty acid disaturase2 (FAD2) and lipid transfer protein (LTP). Genome wide transcriptional profiling analysis using the newly developed Affymetrix Citrus GeneChip® microarray (including 30,171 citrus probe sets) revealed the identification of three different chilling-related regulons: 1,345 probe sets were significantly affected by chilling in both control and CD-treated fruits (chilling-response regulon), 509 probe sets were unique to the CD-treated fruits (chilling tolerance regulon), and 417 probe sets were unique to the chilling-sensitive control fruits (chilling stress regulon). Overall, exposure to chilling led to expression governed arrest of general cellular metabolic activity, including concretive down-regulation of cell wall, pathogen defense, photosynthesis, respiration, and protein, nucleic acid and secondary metabolism. On the other hand, chilling enhanced various adaptation processes, such as changes in the expression levels of transcripts related to membranes, lipid, sterol and carbohydrate metabolism, stress stimuli, hormone biosynthesis, and modifications in DNA binding and transcription factors.
