Feedlot performance, carcass characteristics and meat quality of Nellore and Canchim bulls fed diets supplemented with vitamins D and E

O experimento foi conduzido no setor de confinamento da Unesp, campus de Botucatu, com o objetivo de avaliar a influência da suplementação das vitaminas D e E sobre o desempenho animal, características de carcaça e qualidade de carne de bovinos jovens confinados. Foram utilizados 36 machos inteiros, 18 Nelore (NEL) e 18 Canchim (CAC), de sete meses de idade com peso vivo inicial médio de 234,53 ± 22,15 e 248,13 ± 34,67 kg, respectivamente, os quais foram confinados por 126 dias. Nove animais NEL e nove CAC foram suplementados diariamente com 1300 UI de vitamina E e 7,5x10(6) UI de vitamina D3 durante 67 e dez dias antes do abate, respectivamente. Um dia antes do abate foram coletadas amostras de sangue para avaliação do cálcio plasmático. Na desossa, foram colhidas amostras do músculo Longissimus (LM) para análises como força de cisalhamento, índice de fragmentação miofibrilar, lipídeos totais, concentração de vitaminas D e E e tempo de prateleira. Foi observado aumento (p < 0,01) do nível de cálcio plasmático pela suplementação, o que indica atuação da vitamina D no organismo animal. No entanto, não houve efeito (p > 0,05) da suplementação de vitaminas D e E sobre o desempenho, características de carcaça e qualidade da carne.

Sistema de Aquisição de Baixo Custo para um Dinamômetro Biomédico

Objective: to create a purchasing system for optimizing a low cost device fabrication itself. Method: For this purpose was designed a system which is powered by a 12V battery center. The full bridge of "Wheatstone" is powered by the central battery set to 9V. Results: The sign of the strain has a range of 0 to 30 mV which is amplified filtered by a signal conditioner own manufacturing using an LM 324. The electrical signal then passes to vary from 0 to5V which will be processed in an analog input of PIC microcontroller. Tests for the registration and interpretation of data are through software MyOpenLab. Conclusion: The work is in progress and initial results suggest that the system will be able to measure muscular strength accurately and cost-effective.

Achados radiográficos e ultrassonográficos em equinos com doença do navicular

The distal sesamoid bone, also known as navicular bone, is located inside the hoof, palmar (thoracic limbs) or plantar (pelvic limbs) to distal interphalangeal joint. Its extremities are fixed by collateral medial and lateral sesamoidean ligament and distal impar sesamoidean ligament. Navicular disease diagnostic is made through a thorough clinical exam, nerve blocks and imaging exams. Even though imaging exams are not conclusive, they are essential to evaluate the extension of soft tissue lesions. Radiographic projections used to evaluate navicular bone are lateromedial (LM); dorsoproximal-palmaro/plantarodistal oblíqua (D30Pr-PaDiO); dorsoproximal-palmaro/plantarodistal oblíqua (D60Pr-PaDiO) e a palmaro/plantaroproximal-palmaro/plantarodistal oblíqua (PaPr-PaDiO). This exam allows to identify number and shape alterations of synovial invaginations on the distal (foramem nutricio) in the distal margin of distal sesamoid, osteophytes, enthesophytes and periarticular lesions. There are four ultrasonographic accesses described in literature to evaluate podotroclear apparatus, they are: palmar or plantar distal do the pastern, through the heel bulbs, through coronary band and transcuneal. These images allow a beeter the evaluation of soft tissue next to the distal sesamoid, because it is more sensitive than radiographic exam to evaluate acute lesions in soft tissues and perioesteum

Effect of caffeine on larval mortality of Aedes aegypti: efficiency related to solution concentration and age

In two experiments, the duration of the effect of caffeine (CAF) solutions on larval mortality (LM) of Aedes aegypti was analyzed. In the first, LM was studied using solutions at 0.2, 0.5, 1.0 and 2.0 mg/mL aged from zero to five days in artificial breeding sites exposed to the laboratory environment (LE). In the second, the solutions aged at 1.0, 2.0 and 2.5 mg/mL closed flasks were stored in LE or in the refrigerator (R), and the effect on LM was tested in the experimental breeding sites at 30 days interval. In the first, the duration of the effect increased with the solution age in each CAF concentration. CAF at 1.0 and 2.0 mg/mL, without addition of food, produced 100% LM until 25 days after preparation; with food, at 11 and 18 days, respectively. In the second the effectiveness of CAF solutions lasted up to the seventh month, irrespective of whether they were stored in R or in LE. No adult emerged at any of the CAF concentrations used in second experiment.

Potential utility of melatonin as an antioxidant therapy in the management of sickle cell anemia

This study aimed to assess antioxidant effects of melatonintreatment compared to N-acetylcysteine (NAC) and to their combination in asickle cell suspension. Sickle erythrocytes were suspended in phosphate-buffered saline, pH 7.4, composing external control group. They were alsosuspended and incubated at 37°C either in the absence (experimental controlgroup) or in the presence of NAC, melatonin and their combination atconcentrations of 100 pM, 100 nM and 100 lM for 1 hr (treatment groups).The melatonin influences were evaluated by spectrophotometric [hemolysisdegree, catalase (CAT), glutathione S-transferase (GST), glutathioneperoxidase (GPx), glutathione reductase (GR), glucose-6-phosphatedehydrogenase (G6PDH), and superoxide dismutase (SOD) activities] andchromatographic methods [glutathione (GSH) and malondialdehyde (MDA)levels]. Incubation period was able to cause a rise about 64% on hemolysisdegree as well as practically doubled the lipid peroxidation levels (P < 0.01).However, almost all antioxidants tested treatments neutralized this incubationeffect observed in MDA levels. Among the antioxidant biomarkers evaluated,we observed a modulating effect of combined treatment on GPx and SODactivities (P < 0.01), which showed ~25% decrease in their activities. Inaddition, we found an antioxidant dose-dependent effect for melatonin onlipid peroxidation (r = 0.29; P = 0.03) and for combined antioxidanttreatments also on MDA levels (r = 0.37; P = 0.01) and on SOD activity(r = 0.54; P < 0.01). Hence, these findings contribute with important insightthat melatonin individually or in combination with NAC may be useful forsickle cell anemia management.
