SUMMARYThe current study investigated the effect of offering concentrate supplement to ewes in late pregnancy on twin- and triplet-born lamb heat production at 24–36 h old and performance from birth until lactation day 94 (L94). Twin- (n=40) and triplet-bearing (n=28) ewes were grazed on a 60 mm sward height from day 70 of pregnancy (P70) until L94. From P100, half of the ewes from each litter size were offered 400 g/ewe/day of concentrate sheep pellets. Ewe liveweight and body condition were recorded on P50, 100, 130, 135 and 140. Ewe blood samples were also collected on P130, 135 and 140, and ewe herbage intake was estimated from P133–136 using the n-alkane method. Lamb measurements included liveweight and body size at birth, production of heat using indirect open-circuit calorimetry at 24–36 h old and liveweight at L94. Blood samples were also collected from lambs at 24–36 h old and directly before and after calorimetry measurements. While estimates of ewe herbage intake suggested that substitution of herbage for concentrate did not occur, offering concentrate supplement failed to improve ewe liveweight gain, or birth weight of lambs. Offering concentrate supplement, however, did have a positive effect (P<0·05) on the maximal amount of heat a triplet-born lamb can produce on a per kg of body weight basis (concentrate 21±1·3 W/kg, non-concentrate 17±0·6 W/kg). It also had a positive effect (P<0·05) on lamb square-root-transformed plasma gamma-glutamyl transferase (GGT) concentrations, an indicator of colostrum uptake (concentrate 46±3·1 U/l, non-concentrate 38±2·9 U/l). Irrespective of lamb birth rank, offering concentrate supplement had a positive effect (P<0·01) on liveweight gain per day from birth until L94 (concentrate 261±5·7 g/day, non-concentrate 239±5·8 g/day), although there was no effect on the total weight of lamb reared/ewe. Supplementation with concentrate resulted in triplet-born lambs that produced more heat which may have positive effects on the ability of the newborn lamb to deal with cold stress and potentially its survival. Offering concentrate supplement also produced greater lamb growth in twin- and triplet-born lambs.

Abstract The aim of this study was to determine zootechnical and health performance of Girolando calves born with high or low birth weight, and compare metabolic parameters between groups. The study was carried out on a commercial dairy farm located in Passos, Minas Gerais, Brazil. In this sense, a hundred Girolando calves were divided into 2 groups: Control, which consisted of calves that were born weighing ≤ 35 kg; and HBW, calves that were born weighing > 35 kg. Calves were monitored for zootechnical parameters; epidemiological indexes such as morbidity, mortality, recurrence of diarrhea, pneumonia; as well as serum concentrations of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, cholesterol, triglycerides, paraoxonase1, albumin, urea and globulin). Calves from the HBW group had a higher mortality rate as well as a tendency to more cases of pneumonia, but no effect on zootechnical performance was seen. The reasons for the differences in mortality need to be clarified since our study found no changes in biochemical parameters between the groups. The results allow us to conclude that Girolando calves from in vitro fertilization that are born heavier have a greater chance of clinical complications and a higher mortality rate, but the birth weight does not influence the zootechnical performance.

Background: Stryphnodendron fissuratum is a tree from the Brazilian Cerrado. Its fruit is toxic to cattle and can cause clinical digestive signs, hepatogenous photosensitization, and abortion. Cases of poisoning in cattle, goats and guinea pigs have been experimentally reproduced; however, photosensitization could not be reproduced. The aim of this work was to describe an outbreak of natural poisoning and experimental reproduction in cattle, both with hepatogenous photosensitization.Materials, Methods & Results: Its described and natural outbreak and an experimental poisoning. In the outbreak, three bovines in the acute phase and three in the chronic phase were examined. Blood samples were collected from all of these animals in order to measure serum levels of aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), urea, and creatinine. The first three animals underwent necropsy and histopathological evaluation. The experiment was conducted with two nine-month-old calves that received an oral paste made with crushed S. fissuratum fruits mixed with water. These fruits were collected at a farm at which cattle poisoning cases had occurred. Blood samples were collected in order to measure serum levels of AST, GGT, urea, and creatinine, before plant administration and then daily during the experimental period. Skin biopsies were taken before plant administration and new one after the first signs of skin lesions. The natural outbreak affected 52 of 160 bovine (31 calves and 21 cows) in the lot. Two calves and 14 cows died. Clinical signs consisted of depression, ataxia, incoordination, behavioral changes, decubitus, and death. One animal that died and 36 others that recovered had photodermatitis. Necropsy findings in the animals consisted of bad corporal condition, pale kidneys, evidence of liver lobular pattern, dry rumen contents, and full bladder. In two animals, fruit seeds were found in the rumen, and one animal had ulcers and transmural edema in the abomasum. Microscopically, mild to moderate renal tubular distension, accumulation of proteinaceous material in lumen with mild to moderate swelling, and epithelial necrosis. In the liver, swelling of hepatocytes and moderate bile stasis was detected. Enzymes values in all evaluated bovines were higher than those considered normal for the species. Experimentally, both calves became ill and one died. The clinical signs were apathy, inappetence, wobbling, weight loss, and goosebumps. One of them had jaundice, tearing, photophobia, ear skin detachment, and ulcers at the muzzle, nostrils and ventral face of the tongue. This animal was euthanized in extremis, and the necropsy findings showed generalized jaundice, evidence of increased liver lobular pattern, thick bile, pale kidneys, and esophageal, tongue, and epiglottal ulcers. Microscopically, the lesions were similar to those described during the natural outbreak. The skin biopsy from the calf that recovered showed perivascular edema and mild eosinophilia.Discussion: The diagnosis was made based on clinical signs, necropsy findings, histopathological lesions, and epidemiological analysis. Experimentally, the plant was toxic at the administered doses. Photosensitization was the most common clinical sign during the natural outbreak and until now, has never been experimentally reproduced. Based on histopathological lesions observed in this study, we can consider that is from hepatogenous origin. The results showed that the kidney lesions have an important role during the pathogenesis caused by this poisoning and during disease evolution.

Background: Methotrexate (MTX) is one of the frequently used chemotherapeutic agents, especially in hematological malignancies and solid tumors. Objectives: MTX hepatotoxicity symptoms range from elevations in serum aminotransferases to hepatocyte necrosis and fibrosis. The time of medication administration significantly impacts treatment outcomes. Hence this study evaluated the protective effect of time-modulated cimetidine (CT) against MTX-induced hepatotoxicity in albino rats. Methods: Thirty-six adult male albino rats were randomized into 6 groups. Group A (control) was injected intraperitoneally (IP) with normal saline (0.2 mL) for 24 h. Group B received CT (20 mg/kg IP) for 24 h. Group C was treated IP with MTX (20 mg/kg) for 24 h. Group C (pre-treatment) was injected IP with CT one hour before MTX administration for 24 h. Group E (co-treatment group) was co-treated IP with CT and MTX for 24 h. Group F (post-treatment group) was treated IP with one dose of MTX one hour before CT injection for 24 h. After treatments, the rats were weighed and euthanized. Blood samples were collected and their blood samples were evaluated for serum liver function markers, also liver samples were excised and used for biochemical and histological studies. Results: The liver of MTX-treated rats was characterized by hepatocyte necrosis. Aminotransferases, gamma-glutamyl transferase, lactate dehydrogenase, alkaline phosphatase, conjugated bilirubin, total bilirubin, and malondialdehyde activities were significantly (P<0.001) up-regulated in MTX-treated rats. However, glutathione, catalase, superoxide dismutase, and glutathione peroxidase activities were significantly (P<0.001) down-regulated in MTX-treated rats. The above hepatotoxic changes were significantly attenuated in rats pre-treated (P<0.001), co-treated (P<0.01), and post-treated (P<0.05) with CT when compared to MTX group.  Conclusion: However, pre-treatment with CT was most effective, hence it may be clinically useful for MTX-induced hepatotoxicity.

Forty lightweight calves (206.4±3.2 kg) were randomly distributed to four treatments: (Control) low nutritive value pasture and hay plus 1 kg d−1of rolled barley; (Pasture) management intensive pasture; (Haylage) timothy haylage; and (Kale) 50% timothy haylage −50% kale pasture. Blood samples were analysed for thyroid hormones, liver enzymes, glucose, cholesterol, total proteins (TP), albumin, globulins, and urea-N. At the end of the trial, the Pasture group was the heaviest with323.6±4.2 kg BW and 1.54 kg ADG. Final BW and ADG were similar for the Kale and Haylage groups. Blood T3was higher for Kale than for the other groups. The T3/T4ratio was greater for Control at the end of the experiment. There were no treatment differences for T4, aspartate aminotransferase (AST), gamma glutamyl transferase (GGT), glutamate dehydrogenase (GLDH), cholesterol, and glucose. Blood urea-N was lower for Kale and higher for Pasture; however albumin concentrations were greater for Pasture and similar for other treatments. Except for the Control group, calves had a lower concentration of circulating globulins at the end than at the beginning of the experiment. This study showed that Kale could be fed to backgrounding calves without detrimental effects on performance.

In a study of 3 658 drunken drivers, it was found that eight percent reported daily drinking of alcohol, 82% reported no daily drinking, and 10% gave no information about drinking frequency. Measurements of gamma glutamyl-transferase (a biological marker for heavy drinking) in a selection of blood samples from drunken drivers reporting daily drinking, indicated that the majority of these drivers were heavy drinkers. The drunken drivers who reported daily drinking, had higher blood alcohol concentrations, were responsible for a larger number of previously detected drunken driving offences, and were more prone to being arrested for drunken driving during working days and during daylight hours than other drunken drivers. Among the repeating offenders, it was estimated that 13% would report daily drinking, and 74% would not.

The aim of the current study was to assess the antioxidative effects of the dietary supplementation of olive leaf extract (OLE) in different concentrations compared to those of vitamin E in piglets under conditions of dietary n-3 PUFA-induced oxidative stress. Forty-eight castrated male piglets (10.6 ± 0.99 kg) were fed the following experimental diets: Cont− (low-fat diet, no supplement), Cont+ (high linseed oil diet, no supplement), Vit-E (as Cont+, 105 IU vitamin E/day), OLE-1 (as Cont+, 3.84 mg hydroxytyrosol equivalents (HEQs)/day), OLE-2 (as Cont+, 38.4 mg HEQ/day), and OLE-3 (as Cont+, 96 mg HEQ/day). After 21 days of feeding, the experimental diets, blood and urine samples were collected to assess the extent of the oxidative stress. Results indicated that diet OLE-1 lowered the activity of gamma-glutamyl transferase, protected DNA (measured as DNA tail %) and altered urinary 8-hydroxy-2’-deoxyguanosine (8-OHdG). Dietary vitamin E lowered the levels of urinary F2-isoprostanes, as well as of plasma malondialdehyde and γ-tocopherol, but raised the plasmatic α-tocopherol and altered the level of urinary 8-OHdG. In conclusion, only minor positive effects of dietary OLE on the oxidative stress parameters were observed. Additionally, OLE did not show concentration dependence.

Digitalization is a megatrend, but there is relatively little knowledge about its consequences for service work in general and specifically in knowledge-intensive business services (KIBS). We studied the impact of digitalization on psychological consequences for employees in tax consultancies as a special case of KIBS. We compare two tax consulting jobs with very different job demands, those of tax consultants (TCs) and assistant tax consultants (ATCs). The results show that the extent of digitalization at the workplace level for ATCs correlates significantly positively with their job satisfaction. For TCs, the same variable correlates positively with their work engagement. These positive effects of digitalization are mediated in the case of ATCs by the impact on important job characteristics. In the case of TCs, which already have very good working conditions, the impact is mediated by the positive effect on self-efficacy. Theoretical and practical consequences of these results are discussed.

Light chain deposition disease (LCDD) is a rare multisystemic disorder associated with plasma cell proliferation. It mainly affects the kidney, but liver and heart involvement may occur, sometimes mimicking the picture of systemic amyloidosis. Liver disease in LCDD is usually asymptomatic and exceptionally manifests with severe cholestatic hepatitis. We report the case of a 66-year-old female with κ-LCDD and cast nephropathy in the setting of symptomatic multiple myeloma who, after a first cycle of bortezomib-dexamethasone chemotherapy, developed severe and rapidly worsening intrahepatic cholestasis secondary to liver κ-light chain deposition. Intrahepatic cholestasis was attributed to LCDD on the basis of the liver histology and exclusion of possible diagnoses. Chemotherapy was maintained and resulted in progressive resolution of cholestasis. We report here an uncommon presentation of LCDD, with prominent liver involvement that fully recovered with bortezomib-based chemotherapy, and briefly review the relevant literature.

Objective: To assess the potential hematobiochemical alterations in healthy dromedary camel during the different stages of lactation. Design: Randomized controlled study. Animals: Fifteen healthy female dromedary camels, with mean body weight of 499.6 kg and mean age of 20 years. Procedures: Camels were categorized into 3 groups' according to their stage of lactation: group 1, early lactation (1-3 months), group 2, mid-lactation (four-6 months) and group3, late lactation (≥ 7 months). Blood samples were collected from every animals for hematological and biochemical evaluation. Results: Total erythrocyte count (TEC), hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), total leukocytes (TLC), lymphocytes, neutrophils, monocytes, Calcium, glucose, aspartate aminotransferase (AST), alanine transaminase (ALT), gamma glutamyl transferase (GGT) and alkaline phosphatase (ALP) confirmed significant (p < 0.05) variation between different stages of lactation. However, non-notable (p > 0.05) dissimilarity were located in packed cell volume (PCV), mean corpuscular hemoglobin concentration (MCHC), in organic phosphorus (P), magnesium (Mg), cholesterol, total protein (TP), albumen, globulin, blood urea nitrogen (BUN) and creatinine kinase (CK) in the course of different ranges of lactation, Conclusion and clinical relevance: The results of this investigation may be useful as reference guide for dromedary camel to evaluate the metabolic health status at different stages of lactation.

This in vitro study analyses the biochemical interaction between saliva and three types of dental composite resins (a direct resin, an indirect resin and a dual-cure resin used for cementation of indirect dental restorations). The resin samples were obtained following a specific protocol and in line with the producers� recommendations; the resin samples were incubated with saliva samples collected from 19 healthy volunteers. The obtained results showed that the tested composite resins did not produce significant changes in oxidative stress parameters that were analysed (albumin, uric acid, GGT / gamma glutamyl transferase, OXSR-1 / oxidative stress responsive kinase 1) and do not influence the inflammatory salivary status reflected by the levels of IL-6 - an inflammatory marker.
