Abstract:

Abstract Mine drainage waters are often characterized by high concentrations of sulphates and metals as a consequence of the mining industry of sulphide minerals. The aims of this work are to prove some biological-chemical processes utilization for the mine drainage water treatment. The studied principles of contamination elimination from these waters include sulphate reduction and metal bioprecipitation by the application of sulphate-reducing bacteria (SRB). Other studied process was metal sorption by prepared biogenic sorbent. Mine drainage waters from Slovak localities Banská Štiavnica and Smolník were used to the pollution removal examination. In Banská Štiavnica water, sulphates decreased below the legislative limit. The elimination of zinc by sorption experiments achieved 84 % and 65 %, respectively.

Abstract:

The paper presents the results of the investigation of zinc leach residue (ZLR) processing by sulphatizing roasting with iron sulphates FeSO4 and Fe2(SO4)3 followed by water leaching. The elemental and phase compositions of ZLR of JSC "Chelyabinsk Zinc Plant" were studied. Based on the thermodynamic calculations using HSC Chemistry 9.9 software, the temperature ranges of the sulphatizing roasting and the required amounts of iron sulphate additives for the sulphation of zinc and copper were determined. Subsequent experiments showed that recovery rates of zinc and copper reached 99.5% and 89.1% respectively, while iron remained in the leached residue. The results have indicated a high efficiency of sulphatizing roasting to transform zinc and copper contained in ZLR from ferrite to water-soluble sulphate.

Abstract:

Redissolution of cemented cobalt from zinc sulphate solution occurs, and is a well known problem among zinc producers. A variety of mechanism of cobalt redisisolution have been proposed in the literatures, however, it is still not very well understood. The influencing factors of cobalt redissolution such as detention time, oxidation, particle size of zinc dust and copper ion have been investigated in this paper. The redissolution does not occur when very large particles are used but the redissolution of cobalt is significant from small zinc particles. The redissolution is obvious with copper ion added, while the redissolution is not occurred from the zinc sulphated solution without copper ion added. The redissolution mechanism of cobalt is obtained.

Abstract:

Morphology of Zinc Oxide (ZnO) is an important parameter to enhance the efficiency of optoelectronic devices. Morphology also plays a significant role in gas sensing properties of ZnO. In this research work, different morphologies of Zinc Oxide including nanorods, disks and flakes were obtained using Zinc Acetate, Sodium Dodecyl Sulphate and Trisodium Citrate as additives to a parent solution of Zinc nitrate hexahydrate (Zn(NO3)2·6H2O) and Hexamethylenetetramine (HMTA, (CH2)6N4) for hydrothermal growth. Use of Zinc Acetate as an additive has been rarely reported. This work presents the ability of Zinc Acetate to transform the morphology of ZnO nanorods to nanoneedles. Furthermore, in this study addition of Sodium Dodecyl Sulphate and Trisodium Citrate to the parent solution has shown potential for growing continuous granular films by the low cost and low temperature hydrothermal technique. Variation in crystallite size and band gap values with increasing concentration of Zinc Acetate, Sodium Dodecyl Sulphate and Trisodium Sulphate has been studied. Films with crystallite sizes of 7.48 nm and 6.77 nm were achieved with 5 mM Sodium Dodecyl Sulphate and 5 mM Trisodium Citrate respectively. The band gap of films produced with 5 mM Sodium Dodecyl Sulphate and with 5 mM Trisodium Citrate were 3.43 eV and 3.45 eV respectively. Therefore hydrothermal growth with Sodium Dodecyl Sulphate or Trisodium Citrate is a potential technique for obtaining granular ZnO films.

Abstract:

An extreme thermophilic, iron-sulphur oxidising bacterial culture was isolated and adapted to tolerate high metal and solids concentrations at 70?C. Following isolation and adaptation, the culture was used in a batch bioleach test employing a 5-l glass standard magnetic agitated and aerated reactor, for the bioleaching of a copper-lead-zinc collective concentrate. The culture exhibited stable leach performance over the period of leach operation and overall copper and zinc extractions higher than 97%. Lead sulphide is transformed into lead sulphate remaining in the bioleach residue due to the low solubility in sulphate media. Brine leaching of bioleach residue yields 95% lead extraction.

Abstract:

Mining effluents are major contributors to mineralization of receiving waters and can be toxic to man, animals and plants due to unacceptably high concentrations of heavy metals. A biological sulphate removal process has been developed for the treatment of sulphate-rich industrial effluents, where sulphate is converted via sulphide to sulphur in an anaerobic single-stage reactor. Ethanol is used as carbon and energy source. Sulphate was removed from acid mine water over a period of 95 days from 3000 mg/l down to less than 200 mg/l and the formed sulphides to less than 200 mg/l. The VSS value in the reactor varied between 3 and 4 g/l, resulting in a specific sulphate removal rate from 0.47 to 2.47 g SO4/(g VSS.d), while the volumetric rate was 2.5 and 8.4g SO4/(2.d) at HRT of 18 to 4.3 h. The experimental COD/sulphate ratio was between 0.55 and 0.84, which is in accordance with the theoretical value of 0.67. The experimental sulphide/sulphate ratio was less than the theoretical value of 0.33 due to the conversion of sulphate to sulphur and due to metal sulphide precipitation. Iron and copper were removed completely and aluminium, manganese and zinc to less than 4 mg/l.

Abstract:

Introduction. COVID-19 has rapidly emerged as a pandemic infection that has caused significant mortality and economic losses. Potential therapies and prophylaxis against COVID-19 are urgently needed to combat this novel infection. As a result of in vitro evidence suggesting zinc sulphate may be efficacious against COVID-19, our hospitals began using zinc sulphate as add-on therapy to hydroxychloroquine and azithromycin. Aim. To compare outcomes among hospitalized COVID-19 patients ordered to receive hydroxychloroquine and azithromycin plus zinc sulphate versus hydroxychloroquine and azithromycin alone. Methodology. This was a retrospective observational study. Data was collected from medical records for all patients with admission dates ranging from 2 March 2020 through to 11 April 2020. Initial clinical characteristics on presentation, medications given during the hospitalization, and hospital outcomes were recorded. The study included patients admitted to any of four acute care NYU Langone Health Hospitals in New York City. Patients included were admitted to the hospital with at least one positive COVID-19 test and had completed their hospitalization. Patients were excluded from the study if they were never admitted to the hospital or if there was an order for other investigational therapies for COVID-19. Results. Patients taking zinc sulphate in addition to hydroxychloroquine and azithromycin (n=411) and patients taking hydroxychloroquine and azithromycin alone (n=521) did not differ in age, race, sex, tobacco use or relevant comorbidities. The addition of zinc sulphate did not impact the length of hospitalization, duration of ventilation or intensive care unit (ICU) duration. In univariate analyses, zinc sulphate increased the frequency of patients being discharged home, and decreased the need for ventilation, admission to the ICU and mortality or transfer to hospice for patients who were never admitted to the ICU. After adjusting for the time at which zinc sulphate was added to our protocol, an increased frequency of being discharged home (OR 1.53, 95 % CI 1.12–2.09) and reduction in mortality or transfer to hospice among patients who did not require ICU level of care remained significant (OR 0.449, 95 % CI 0.271–0.744). Conclusion. This study provides the first in vivo evidence that zinc sulphate may play a role in therapeutic management for COVID-19.

Abstract:

Abstract The zinc deposition reaction onto metallic zinc has been investigated at the single particle level through the electrode-particle collision method in neutral solutions, and in respect of its dependence on the applied potential and the ionic strength of a sulphate-containing solution. Depending on the concentration of sulphate ions in solution, different amounts of metallic zinc were deposited on the single Zn nanoparticles. Specifically, insights into the electron transfer kinetics at the single particles were obtained, indicating an electrically early reactant-like transition state, which is consistent with the rate-determining partial de-hydration/de-complexation process. Such information on the reaction kinetics at the nanoscale is of vital importance for the development of more efficient and long-lasting nanostructured Zn-based negative electrodes for Zn-ion battery applications.

Abstract:

SUMMARYField experiments were conducted in a zinc-deficient flood plain alluvial soil to study the effect of amounts, methods and sources of zinc application on the yield and uptake of zinc by wheat. Zinc was applied at 0, 5 and 10 kg Zn/ha as zinc sulphate and zinc oxide either broadcast and mixed in the soil or drilled below the seed. Spray application of zinc was also tested. Irrespective of the source, grain yield and zinc uptake significantly increased up to 10 kg Zn/ha. Soil-applied zinc was highly correlated with yield and zinc uptake in the two field experiments. Grain yield was also found to be significantly correlated with zinc content of grain (r = 0·78), straw (r = 0·72) and flag leaf (r = 0·66). When applied at the rate of 10 kg Zn/ha, broadcasting of zinc sulphate and drilling of ZnO below the seed were equally effective in increasing grain yield of wheat. Foliar spray of zinc sulphate was an effective emergency method, but in highly zinc-deficient soils it did not compare well with soil application of zinc.

Abstract:

An upflow fixed-bed sulphate-reducing reactor has been set up and monitored for the treatment of metal-bearing wastewater. Zinc has been chosen as the target metal to be sequestered from influent water stream at initial concentrations ranging from 50 to 400 mg/l and initial pH values ranging from 3 to 5. Main operating parameters of the reactor, such as the composition and content of electron donor, electron acceptor, sulphate and metal removal capacity, have been monitored during ten months of continuous operation. The results obtained have shown that the reactor has a considerable capacity of completely reducing sulphates for initial concentrations up to 7,200 mg/l, completely removing soluble zinc for initial concentrations up to 400 mg/l and completely removing Total Organic Carbon (TOC), for initial concentrations up to 1,500 mg/l.

Abstract:

The purpose of this study was to assess the toxic effects of heavy metal compoundsÂ like Cadmium chloride (CdCl2) and Zinc sulphate (ZnSo4) on respiratoryÂ metabolism of the freshwater mussel Lamellidens consobrinus.The effectÂ was observed for 24, 48, 72 and 96 h exposure. On exposure of musselsÂ to toxic concentrations the respiratory metabolic rate was found profoundlyÂ decreased after two hours of intoxication in Cadmium chloride (0.0863 Â±Â 0.0032 mg/gm/l/h) and Zinc sulphate (0.1517 Â± .0018 mg/gm/l/h). The oxygenÂ consumption was continuously decreased up to 96 h in CdCl2 (0.0303 Â±Â 0.0019 mg/gm/l/h) and ZnSo4 (0.0746. Â± 0.0019 mg/gm/l/h).The decrease inÂ metabolic rate was more prominent in cadmium chloride than zinc sulphate.Â This impact may be due to inhibition of enzymatic pathways and osmoregulatoryÂ response which depends on the time of exposure to heavy metal compoundsÂ used for experimental work.

Abstract:

Depriving homing pigeons of olfactory information by applying a local anaesthetic, gingicain, to their olfactory epithelium results in systemic effects. Furthermore, anosmia persists reliably for only an hour. In contrast, intra-nasal irrigation with 18 % zinc sulphate solution results in anosmia that persists for at least 5 days. No systemic effects of zinc sulphate on anosmic pigeons could be detected while monitoring their olfactory capabilities using the orienting response. To compare the orientation and homing of definitely anosmic, zinc-sulphatetreated pigeons with those of controls, I made releases from two different distances (9–24km, 63–70km). At shorter distances, pigeons treated with zinc sulphate showed no directional preference in their vanishing bearings, whereas both groups of control birds (sham-treated controls and untreated super controls) were well oriented. At the longer distances, the situation was more complex: pigeons treated with zinc sulphate were oriented but the chosen direction did not correspond with the home direction. The control groups did not show any directional preference. In all cases, fewer anosmic pigeons homed and they did so more slowly than did the controls

Abstract:

Long term lab-scale and bench-scale experiments were performed to investigate the feasibility of the anaerobic process to treat wastewater from a pulp and viscose fibre industry. Anaerobic wastewater treatment enables an advantageous combination of COD, sulphate and zinc removal from viscose wastewater. The aim of the investigations was to evaluate the influence of the free sulphide concentration on COD and sulphate removal efficiency and on the substrate competition between sulphate reducing and methanogenic bacteria. Since the wastewater did not contain enough COD for complete sulphate removal it was of major interest to determine favourable process conditions to steer the substrate competition in favour of sulphate reduction. Further experiments at bench-scale permitted us to evaluate applicable COD-loading rates and gain fundamental information about process stability and optimization for large-scale implementation. The present work will deal with the most relevant experimental results achieved and with important technological aspects of anaerobic treatment of viscose wastewater.

Pregnant Hereford cows (n = 99) and heifers (n = 98) whose ration contained 10 mg Cu kg−1 DM and 20 mg Zn kg−1 DM were assigned to two treatments. The water supply (sulphated water) for one group contained 500 mg S L−1 as sulphates. The sulphates in the water (desulphated) for the other group had been decreased to 42 mg S L−1 by reverse osmosis. Changes in plasma and liver copper and zinc concentrations were monitored in the cows and their calves during the winter drylot and pasture periods. The initial plasma and liver copper concentrations in all cows indicated a deficient status. At calving, the plasma copper concentration had declined in both groups. The greatest decrease was evident in the cows on sulphated water. At calving, the liver copper concentration had declined in both water treatment groups but was lowest in the cattle on the sulphated water. After calving, plasma and liver copper concentrations in both groups increased; this increase was greatest in the cows drinking the desulphated water. Water treatment had no effect on the copper status of the nursing calves. Water purification had a positive effect on the body weights of first and second calf heifers. Although the zinc status was normal, the plasma zinc declined and liver zinc increased in the cows at calving. These changes were independent of water treatment. When the sulphur in the drinking water was decreased to 42 mg L−1 by reverse osmosis there was a positive effect on the copper status of beef cows. Further research is required into higher dietary copper intakes, as 10 mg Cu kg−1 DM was not adequate in improving the deficient copper status of these cattle.

Abstract:

ABSTRACT Mechanical damage of seeds due to harvest, handling and other process is an important factor that affects the quality and quaintly of seeds. Seed damage results in lower grain value, storability problem, and reduces seed germination and seedling vigor and subsequent yield of crops. The objectives were to determine the effect of different levels of zinc sulphate fertilization on the breakage susceptibility of three irrigated wheat varieties (Bahar, Shiraz and Pyshtaz). An experiment was conduct at the Experimental research station of Lorestan University, Iran. A factorial experiment was conducted with three replicates in a completely randomized block design (CRBD). Factors included three levels of zinc sulphate. Zinc sulphate treatments were combinations of three fertilization rates (0 - control, 25 and 50 kg/ha) at three replicates. The harvested seeds were subjected to impact energies of 0.05 and 0.1 J at constant moisture contents of 9.8, 15 and 20% using an impact test apparatus. The analysis of variance showed that wheat variety, fertilization level of zinc sulphate and moisture content significantly influenced breakage susceptibility of wheat seeds at the 1% probability level. Resistance to the breakage of wheat seeds for all varieties increased, as polynomial functions, with increase in the zinc sulphate rate. The average values of percentage breakage of seeds decreased from 37.07 to 27.80% as the fertilization level of zinc sulphate increased from 0 to 50 kg/ha. Bahar variety exhibited the highest resistance to breakage than other varieties. As the moisture content increased from 9.8 to 20% the percentage breakage of seeds decreased from 36.58 to 30.03%. Increasing the impact energy from 0.05 to 0.1 J caused an increase in the percentage breakage of seeds from 16.19 to 50.47%.

Abstract:

The aim of this study was to compare the effects of organic dietary zinc (Zn) sources and zinc sulphate on mineral deposition, activity of total superoxide dismutase (SOD) and copper/zinc SOD in tissues of broiler chickens. The performance indicators and lipid peroxidation by measuring the contents of thiobarbituric acid reactive substances (TBARS) in tissues and plasma were also evaluated. Broilers were assigned to 4 treatment groups, each replicated × 6, with 9 birds per replicate. The control group was fed conventional basal diet (BD); the three other groups received identical BD supplemented with 120 mg Zn/kg in the form of zinc sulphate, zinc chelate of glycine hydrate (Zn-Gly), and zinc proteinate (Zn-Pro), respectively. After 5 weeks of dietary treatment, feed supplementation with Zn sulphate resulted in significantly higher average daily weight gain and final body weight, as well as improved feed conversion ratio compared to the Zn-Gly group. Intake of Zn-Pro significantly increased SOD activity (P < 0.05) in erythrocytes and lipid peroxidation (P < 0.01) in plasma. Activities of total SOD and Cu/Zn SOD in liver and kidney were not affected by Zn supplementation. Addition of Zn supplements to broiler diets did not influence concentrations of zinc, manganese and copper in plasma, liver, kidney or breast muscle, with the exception of Zn deposition in the liver being significantly higher (P < 0.05) in the Zn-Pro supplemented group. Results of our study show that organic zinc sources have effects comparable to inorganic zinc sulphate in broilers fed diets containing a higher Zn content.

Abstract:

Mineral deficiencies for livestock are reported from almost all world regions. Deficiency can be caused by inadequate intake or by the presence of antagonists in the diet. Traditionally, inorganic salts, such as oxides and sulphates have been added to the diet to meet the requirements of the animal. More recently, there has been increasing interest in mineral chelates. Studies by Rojas et al. (1995) and Ward et al. (1996) have reported that the copper and zinc availability in copper and zinc chelates is greater than in the traditional inorganic salts. Other studies by Kegley et al. (1994) and Schell et al. (1996) reported contradictory results. In this study, two separate trials were carried out to compare the effects of Bioplex copper and Bioplex zinc with the effects of copper and zinc sulphate on plasma copper and zinc levels in adult Texel sheep.

Abstract:

BACKGROUND Acne vulgaris is a chronic inflammatory condition of the pilosebaceous unit which occurs in adolescent age groups. Physical and psychological scars can create social issues in the family, school and workplace. The disorder is multifactorial. There are plenty of recovery choices but are not satisfactory. We wanted to investigate the serum zinc levels and the therapeutic utility of oral zinc supplementation in acne vulgaris patients. METHODS This is a prospective study conducted over a period of one and a half years among one hundred acne patients who reported to the outpatient clinic of the Department of Dermatology, Venereology and Leprology with untreated patients of acne vulgaris. RESULTS Males were 65 % and females were 35 % with male : female ratio of 6.5 : 3.5. Most of the patients were students occupying 71 % of the study. Family history was observed in 46 % of patients, either in the siblings or in the parents. Premenstrual flare-up of acne lesions was noted in 71.42 % of female patients indicating a pivotal role of hormones in the pathogenesis of acne. Aggravation of lesions in summer was noted in 45 % of patients. Aggravation of acne lesions with different types of diet like non-vegetarian food, oily food and chocolates was noticed in 69 % of the study. History of usage of different types of cosmetics available in the market was noted in 76 % of the patients. In the present study, 62 % had lower than normal serum zinc levels and 38 % had normal serum zinc levels. Thus, serum zinc levels were found to be lower in both male and female acne patients in the majority (62 %) of the study patients and also normal healthy controls. The fasting serum zinc levels in the 62 patients before and after oral zinc sulphate were estimated after completion of 3 months treatment. Normal serum zinc levels were observed in all 62 patients treated. CONCLUSIONS Oral zinc sulphate is an effective, safe and economic remedy in the treatment of acne vulgaris. The extra advantage with oral zinc sulphate is that it is devoid of many adverse reactions commonly seen after prolonged use of systemic antibiotics. KEYWORDS Oral Zinc Sulphate, Acne Vulgaris

Abstract:

The paper presents the morphology, topography and corrosion behavior of epoxy resin/zinc hybrid coatings obtained by electrodeposition from zinc sulphate electrolyte. The effect of current density and mean diameter size of polymer particles used for electrodeposition of the epoxy resin/zinc coatings on the morphology, topography and roughness of the surfaces were investigated by Scanning Electron Microscopy and Atomic Force Microscopy. The corrosion behavior of the hybrid coatings in 0.5 M sodium chloride solution was evaluated using electrochemical methods. For microbiological corrosion, the effect of sulphate reducing bacteria (SRB) on the surfaces was evaluated using epifluorescence microscopy. The surface roughness before and after bacteria attachment was evaluated using Atomic force microscopy. Polymer particles provide an influence in restricting the growth of zinc crystals as well as a catalytic role in nucleation sites increase. The results of electrochemical tests indicate a very good corrosion resistance of hybrid coatings comparing with zinc coatings. Epifluorescence images demonstrate that hybrid coating surfaces are slightly attacked by sulphate reducing bacteria.

Abstract:

Bioleaching treatment of complex multi-metallic Cu-Zn-Pb-Ag-Au mineral concentrates leds to the formation, besides easily soluble zinc and cooper sulphates, of hardly soluble lead (II) sulfate (PbSO4) sludge. To determine the leaching parameters of PbSO4 with NaCl in the bioleaching residue, lead sulphate solution was synthetically prepared. The effect of process parameters, namely NaCl concentration, solid:liquid phase ratio, processing time, temperature and Cl ions was examined. It was found that 100% Pb by leaching can be achieved with NaCl concentration of 250 g/dm3, time 20 min, temperature 353 K and solid:liquid phase ratio =1:20.

Abstract:

AbstractForty-eight pigs, weaned at 27 days of age at an average body weight of 7·55 kg were used in a 19-day experiment to investigate the influence of microbial phytase on zinc utilization and to calculate equivalency values of zinc as sulphate for microbial phytase. Eight experimental diets were formulated: a maize-soya-bean meal basal diet containing 30 mg of zinc per kg supplemented with 10, 25, 40 or 100 mg of zinc from sulphate (ZnSO4, 7H2O) per kg or with 100, 250, 500 or 750 units (U) of microbial phytase (3- phytase from Aspergillus niger, Natuphos ®) per kg. The dietary supplies of calcium and phosphorus were adjusted accounting for the release of these elements by microbial phytase. The copper concentration in the diets was 11 mg/kg. Pigs were given the basal diet for a 7-day adjustment period prior to the 19-day experimental period. At the end of the experiment, bone ash, phosphorus and calcium concentrations as well as plasma and liver copper concentrations were independent of the diet (P> 0·10). The zinc status of piglets was assessed through plasma alkaline phosphatase activity (APA) and zinc concentration, bone zinc concentration and liver zinc concentration. Plasma zinc, plasma APA and bone zinc increased linearly (P< 0·001) and quadratically (P< 0·01,P< 0·001 andP< 0·001, respectively) with zinc added. These parameters also increased linearly (P< 0·001) and quadratically (P< 0·05,P< 0·001 andP< 0·05, respectively) with phytase added. Liver zinc increased quadratically (P< 0·05) with zinc added and tended to increase linearly with phytase added (P= 0·077). Linear and non-linear response equations of indicators of zinc status to zinc added and phytase added were developed and used to calculate zinc equivalency values of phytase. Non-linear models were linear plateau models for zinc added and exponential models for phytase added. Plasma APA, plasma zinc and bone zinc were maximized when zinc added reached 43, 54 and 56 mg/kg of diet, respectively. The mean function of equivalency of zinc as sulphate (Zn, mg/kg of diet) for microbial phytase (Phyt, U per kg of diet) was Zn = 49·9 − 58·3 e−0·00233Phyt. From this equation it is calculated that 250, 500, and 750 U of 3-phytase from Aspergillus niger can avoid the addition of 17, 32 and 40 mg of zinc as sulphate in a piglet diet. Zinc ingested and, in turn, zinc excreted, may be proportionately reduced by almost 0·30 by replacing 30 mg of zinc as sulphate by 500 U of phytase as Natuphos ® in a piglet maize and soya-bean meal diet formulated to contain 100 mg of zinc per kg.

Abstract:

Abstract Ciprofloxacin bioavailability may be reduced when ciprofloxacin is co-administered with metallic ion containing preparations. In our previous study, physicochemical interaction between ciprofloxacin and ferrous sulphate was successfully simulated in vitro. In the present work, comparative in vitro ciprofloxacin solubility and dissolution studies were performed in the reactive media containing aluminium hydroxide, calcium carbonate or zinc sulphate. Solid phases collected from the dissolution vessel with aluminium hydroxide, calcium carbonate and zinc sulphate were investigated for their properties. The results obtained indicate that different types of adducts may form and retard ciprofloxacin solubility and dissolution. In the case of aluminium, no phase changes were observed. The solid phase generated in the presence of calcium carbonate was identified as hydrated ciprofloxacin base. Similarly to iron, a new complex consistent with Zn(SO4)2(Cl)2(ciprofloxacin)2 × nH2O stoichiometry was generated in the presence of relatively high concentrations of ciprofloxacin hydrochloride and zinc sulphate, indicating that small volume dissolution experiments can be useful for biorelevant dissolution tests.

Abstract:

The importance of atmospheric odours for homing pigeon navigation in a desert environment was tested using birds from two lofts located in the Sonoran desert near Tucson, Arizona, USA. When released from a familiar training site, experienced control pigeons and pigeons given intranasal injections of zinc sulphate to produce anosmia both displayed good homeward orientation and homed rapidly. When released from two unfamiliar locations, in contrast, the controls continued to display good homing performance while the zinc-sulphate-treated pigeons homed poorly. Significant differences in vanishing bearings, homing time and homing success were recorded. When a group of control and a group of zinc-sulphate-treated inexperienced pigeons were released from two unfamiliar locations, both groups homed poorly. Nonetheless, the controls still outperformed the zinc-sulphate-treated birds, the most notable result being a significant difference in homing success. Taken together, these results highlight the importance of atmospheric odours for the operation of the navigational map of the homing pigeon in a desert environment and, together with previous experiments, demonstrate that the role of atmospheric odours in homing does not seem to vary in any salient way with ambient climatic conditions. <P>

Abstract:

Passive transfer of immunity in dairy calves is routinely monitored in North America. This study analyzes such type of biochemistry monitoring in 591 calves (Holstein, Fleckvieh) from 19 large farms in the Czech Republic. All calves, aged 1–6 days, were blood sampled once. Serum concentrations of total protein, albumin, zinc sulphate turbidity units and γ-glutamyltransferase activity were analysed by photometry methods. The samples were divided according to concentrations of total protein and zinc sulphate turbidity units, and the age of calves. These groups were compared using nonparametric tests. The samples had good mean values (total protein 63.5 g·l-1, albumin 30.5 g·l-1, zinc sulphate turbidity 11.5 U, γ-glutamyltransferase 10.7 μkat·l-1) but 41% and 54% of calves had low total protein (< 60 g·l-1) and zinc sulphate turbidity (< 12 U), respectively. The calves with low total protein showed markedly worse values in all indicators (P < 0.001). The groups according to zinc sulphate turbidity (thresholds 5, 10, 15 U) demonstrated gradual differences (P < 0.001) in all indicators except albumin. Only γ-glutamyltransferase showed very distinct age-sensitive differences; the highest activity was in 1-day-old calves (18.3 μkat·l-1); calves aged 3–6 days had significantly lower activity. It is newly suggested that samples be taken from calves 1–3 days old for γ-glutamyltransferase analysis and traditionally anytime during the first week of life for all other indicators. This first extensive analysis of passive transfer in Central Europe shows that there are widespread deficiencies in the feeding of colostrum to calves.

Abstract:

Introduction: Diabetes Mellitus is a common metabolic syndrome characterized by persistently elevated blood glucose levels. Canagliflozin is an SGLT-2 inhibitor that controls hyperglycemia by reducing the reabsorption of filtered glucose and excreting it in the urine. Zinc sulphate exhibits some beneficial role in diabetes mellitus but has not been compared to canagliflozin individually and in combination. Aims & Objectives: To observe the effects of treatment with canagliflozin and zinc sulphate on pancreatic histology in streptozotocin induced type-2 diabetic rat model. Place and duration of study: The study was conducted in the Department of Pharmacology, KEMU and PGMI, Lahore for the period of two months. Material & Methods: It was an animal experimental study of eight weeks duration in which 48 adult healthy albino rats of male gender were divided into six groups and were provided the high fat diet throughout the study period. Groups A and B were maintained as healthy and diseased controls respectively. Groups B, C, D, E and F were administered single I/P dose streptozotocin (35mg/kg) at day 22 for inducing diabetes. Upon confirmation of diabetes after a week the rats were further treated as per group designation orally for 4 weeks , individually or in combination with full or half doses of canagliflozin (10 mg /kg/day, 5mg/kg/day ) and zinc sulphate (30mg/kg/day, 15mg/kg/day) . All animals were euthanized at the completion of study duration. The pancreatic tissue was taken out and examined for the histopathological changes (size and number of pancreatic islets, karyolysis and ballooning degeneration). Results: There was a marked improvement in the size and number of islets as well as the inflammatory changes in the combined treatment group (with canagliflozin in full as well as half dose of zinc sulphate) as compared to the groups given zinc sulphate and canagliflozin separately. Conclusion: Combined treatment with canagliflozin and zinc sulphate has a better protective effect on the pancreatic tissue in diabetes than either of them used alone.

Abstract:

SummaryA field experiment on an alkali soil (ESP 94) studied the effect of gypsum applied at 0, 2·5, 5 and 10t/ha and zinc sulphate applied at 0, 10, 20, 30 and 40 kg/ha on the growth, yield and chemical composition of rice. The effects of gypsum and zinc applications were additive. Optimum response of rice was to 10 kg zinc sulphate/ha at the 5 and 10 t/ha gypsum levels. At low levels of gypsum, plant growth was poor owing to toxicity of Na and/or deficiency of Ca, and higher levels of zinc sulphate gave a yield response. Zinc-deficient plants had significantly lower Zn concentration but higher concentrations of Fe, Mn, Cu, Ca and Mg than the healthy plants. Application of gypsum decreased the concentration of Na, Fe and Zn in rice plants and increased the concentration of Ca, K, Mn and Cu. in plots not treated with gypsum, the Zn concentration of plants was higher but grain yield was lower than that of gypsum-treated plots. Application of zinc increased the DTPA-extractable Zn but gypsum decreased the soil sodicity and DTPA-extractable Zn in alkali soils.

Full text

Abstract:

Zinc supplied as a fulvic-based Zn compound was absorbed and retranslocated to unsprayed new growth as effectively as zinc sulphate in apple seedlings of low Zn status grown hydroponically in the greenhouse. Similarly, fulvic- and humic-based compounds were as effective as zinc sulphate at improving short-term growth and Zn uptake into new tissues in Zn-deficient apple seedlings, with the best growth occurring at spray concentrations of Zn at 500 mg·L-1. Under field conditions, Zn concentration of peeled and washed `Jonagold' apples at harvest was increased, without phytotoxicity, by two or four postbloom sprays of fulvic Zn. It is therefore possible to use this material safely as an effective Zn-source after bloom. However the mobility of the foliar-applied Zn is limited and any yield response by treated apple orchards of marginal Zn nutrition is unlikely to occur in the short term (within two growing seasons).

Abstract:

Abstract Uptake of acridine orange resulting from increased eggshell permeability is a reliable predictor of hatching for Globodera rostochiensis eggs. We conducted laboratory experiments to determine whether fluorescence of Heterodera glycines eggs stained with acridine orange correlated with hatching. Heterodera glycines eggs were incubated in sterile distilled water, zinc sulphate or soybean root diffusate and were stained with acridine orange 24 h prior to assessing fluorescence. Fluorescence of mature eggs positively correlated with hatching in zinc sulphate. Correlations in soybean root diffusate were positive, negative or non-existent, depending on the concentration of the diffusate. Although there were some significant correlations between hatching and fluorescence of H. glycines eggs in zinc sulphate, the relationships were not sufficiently consistent for this technique to be used reliably to predict H. glycines hatching in soybean root diffusate.
