Variação da ecogenicidade difusa em parênquima hepático homogêneo relacionada aos achados bioquímicos e hematológicos em cães

The present study evaluated the liver with homogeneous parenchyma in dogs, with diffuse reduced echogenicity (G1), increased echogenicity (G2) and normal echogenicity (G3) by ultrasound examination associating the findings on animal profile, liver size and hematology and biochemistry results. Blood samples obtained by cephalic or jugular venipunture were submitted for hemogram and ALT, ALP, total proteins, albumin, globulin, urea and creatinine analysis. Among the 30 dogs in G1, 30 (100%) presented portal venous and gall bladder wall clarity, 23 (76.67%) presented normal liver size and edges, 15 (50%) were from 1 to 6 years old and 8 (26.67%) belonged to the lhasa apso breed. No predispositions were found according to gender, as well as no significant alterations in biochemical and hematological exams were observed in G1. The most prevalent disease found in this group was gastroenteritis (43.33%). Among the 30 dogs in G2, 27 (90%) presented hepatomegaly and rounded hepatic edges, 18 (60%) were over 9 years old, 16 (53.33%) were female and 9 (30%) belonged to the poodle breed. The laboratorial findings related to this group were increased ALT and ALP serum activity, decreased levels of total protein, albumin, globulin, erythrocytes and hematocrit, as well as leukocytosis with neutrophilia and a left shift, eosinopenia, lymphopenia and monocytosis. The most prevalent diseases found in this group were metabolic disorders (54%), such as diabetes mellitus and hyperadrenocorticism, and chronic hepatopathies (17%) due to prolonged and continuous use of corticoid and anticonvulsive drugs. Among the 30 dogs in the control group (G3), normal liver size and edges were presented in 22 (73.33%). In this group, no alterations were seen in laboratorial exams.

Feed type for induced molting of commercial layer hens

An experiment employing three hundred and twenty 81-week-old Lohmann LSL commercial-breed hens was conducted to compare alternative induced-molting methods with the conventional method (fasting). Induced molting lasted 28 days at most, production and quality being monitored for four periods of 28 days thereafter. A completely randomized experimental design with five treatments, eight replicates of eight birds each per plot was adopted. The following experimental treatments were applied until a loss of 26% of body weight was reached: T1 - fasting, T2 - wheat bran ad libitum, T3 - rice bran ad libitum, T4 - cracked rice ad libitum, T5 - ground alfalfa ad libitum. Birds were then fed production diet ad libitum, except for those on treatment T1 (fasting) which received 30, 60 and 100 g/bird/day and then feed ad libitum. During induced molting the birds were exposed to a natural photoperiod and at day 28 that period was increased by 30 minutes/week until reaching 16 hours of light/day. The characteristics evaluated during induced molting were: feed intake, body weight changes and laying percentage. In the post-molt period, performance (feed intake, laying percentage, egg weight, egg mass, feed conversion ratio per dozen and per egg mass and percentage of broken eggs) and egg quality (specific gravity, eggshell breaking strength, percentages of eggshell, yolk, and albumen, eggshell thickness, yolk color and Haugh unit) were evaluated. Every 28 days one egg was collected from each repetition for three consecutive days for quality assessment. The use of rice bran and wheat bran is viable as molting inducers since the birds given those treatments display performance and egg quality similar to those fasted during the induced molting and also because these ingredients promote easier handling, eliminates the need for grinding and feed-mixing equipment and, being less aggressive, provide greater bird welfare.

Isolation, Culture and Differentiation of Buffaloes Bone Marrow Mesenchymal Stem Cells Obtained from the Coxal Tuberosity

Currently, much attention has been devoted to the renewal of knowledge about Stem Cells and Cell Therapy in domestic species. In this sense, the present work aimed to develop a methodology for collecting, processing and cultivation of mesenchymal stem cells obtained from bone marrow of coxal tuberosity in buffaloes. The collection was performed using a Komiyashiki needle, which was introduced in the coxal tuberosity and the bone marrow aspirated into a heparinized syringe with the aid of negative pressure. Directly after collection samples were processed at the laboratory at FMVZ - UNESP. The samples took approximately 32 days to reach 80% confluence, when the first passage and differentiation was performed. To confirm the mesenchymal origin, cells were induced to differentiate into adipogenic and osteogenic lineages. Samples showed morphological changes during differentiation protocol, but not all presented production of extracellular deposits of calcium or intracellular fat droplets, observed after staining with Alizarin Red and Oil Red respectively. Compared with the material obtained from other species and processed in the same laboratory, the primary culture was longer. Therefore, more studies are needed to standardize the age of animals used and to test other inducers of cell differentiation.

Environrnental issues are in focus lately, mainly due to climate change that have been registered in recent decades. Some of these changes are attributed to the increased atmospheric concentration of greenhouse gases induce, main1y due to anthropogenic emissions. These gases act by absorbing heat in the form of electromagnetic radiation emitted by the planet, and after a time interval, reissuing such radiation in various directions, including back to the surface, causing overheating of the same. Projections indicate that climate change wiIl tend to increase even more. Because of this, in recent years a number of studies are being conducted on the dynamics of inducers of greenhouse gases, especially C02, because that is primarily responsible for the development of that phenomenon. To better understand the flow of C02 are studied specific areas, as regions bordering the forests, soils that are under preparation for agriculture, urban areas, among others. Forests are an important sink for C02, because during the process of photosynthesis, this molecule is captured and used to obtain glucose. Thus, studies of the regions bordering the forests contribute enough to the understanding of the dynamics of C02. Because it requires a large amount of factors, the concentration of CO2 in a given location is very variable and this makes it much more difficult to understand their dynamics and, consequently, the action of the enhanced greenhouse effect. Being a relatively new area of study, there are many controversies about the consequences of the greenhouse effect, so that the community does not believe that climate change resulting from human action. According to them, such changes are merely natural phenomena and periodicals
