The dynamics of topographic changes in the intestines of quails in terms of age has been investigated. For the study, quail of the day-old, 10-day-old and 30-day age of the Texas breed were selected. In the course of the study, it was found that with age, the intestines of quails increase in size, which is a determining factor in the topography of this organ in the abdominal cavity. It was also found that a Meckel diverticulum appears in the place of a rudimentary yolk sac in quails and an increased development of adipose tissue accumulations occurs.

Meckel Diverticulum

Meckel's diverticulum, according to various statistics, is found in cases of celiac disease in approximately 0.1-1.0% of patients. PN Yurovskaya observed 14 cases of Meckel diverticulum among 1126 patients who underwent laparotomy. During gluttony, the specified diverticulum comes across not only as an accidental find, but often turns out to be the cause of catastrophes in the abdominal cavity: intestinal obstruction, peritonitis, intestinal bleeding, etc. T.

Visceral Adipose

Visceral adipose tissue (VAT)—fat stored deep in the abdominal cavity that surrounds vital organs—is associated with a variety of chronic health conditions. Computed tomography and magnetic resonance imaging are the gold standards to quantify VAT. However, the high cost, limited accessibility, and potential exposure to radiation limit the use of these imaging modalities. In this commentary, we review the application of a previously validated regression equation that estimates anthropometrically predicted VAT (apVAT) to explain variance in blood-based biomarkers and predict mortality in a large sample of adults. In our first study (Brown et al. 2018 Eur J Nutr; doi:10.1007/s00394-016-1308-8), apVAT accounted for more variance in biomarkers of glucose homeostasis, inflammation, and lipid metabolism, than body mass index (BMI), waist circumference (WC), or the combination of BMI + WC. In our second study (Brown et al. 2017 Am J Hum Biol; doi:10.1002/ajhb.22898), compared with BMI, WC, and BMI + WC, apVAT more accurately predicted mortality from all causes, cardiovascular disease, and cancer. These studies demonstrate that apVAT can be used in clinical practice and in clinical nutrition and metabolism research when imaging modalities to quantify VAT may not be feasible.

Assisted reproduction techniques have improved agricultural breeding in the bovine. However, important development steps may differ from the situation in vivo and there is a high mortality rate during the first trimester of gestation. To better understand these events, we investigated the development of embryos and fetal membranes following fixed-time AI (FTAI), IVF and nuclear transfer (NT). The onset of yolk-sac development was not normal in cloned embryos. Later steps differed from conditions in vivo in all three groups; the yolk-sac was yellowish and juxtaposed with the amniotic membrane. Vascularisation of the chorioallantoic membrane was relatively late and low in NT gestations, but normal in the others. The overall development of the embryos was normal, as indicated by morphology and regression analysis of growth rate. However, NT conceptuses were significantly smaller, with the livers in some embryos occupying the abdominal cavity and others exhibiting heart abnormalities. In conclusion, the yolk-sac and the cardiovascular system seem to be vulnerable to morphogenetic alterations. Future studies will focus on gene expression and early vascularisation processes to investigate whether these changes may be responsible for the high incidence of intrauterine mortality, especially in clones.

Due to problems such as unbalanced intake of nutrients or excessive intake of energy, cultured fish accumulate fat in places such as the abdominal cavity, liver, and muscle, resulting in fatty liver, reducing the quality of fish meat, and even causing many fish deaths, resulting in losses to aquaculture production. Therefore, research on lipid metabolism in fish is important and has attracted increasing attention. The detection of fish body fat distribution and content is a key to such research. The existing methods for detecting fat distribution and content in fish have limitations, such as cumbersome procedures and damage to fish tissues, and thus, is imperative to develop a simple, fast, nondestructive fat detection technology. Taking zebrafish as the research material, this study established an imaging technology for the rapid and nondestructive detection of the fat distribution and content of fish by micro-computed tomography (micro-CT), optimized the fat CT-scanning method, determined the steps of fat quantitation in the CTAn data processing software, and constructed a three-dimensional (3D) model of zebrafish adipose tissue. This technology reveals the distribution of fish adipose tissue in an all-round way, and thus, it will play an important role in the study of lipid metabolism in fish.

Possible Cause

The distribution of fat in the human body is related to hemodynamic and metabolic homeostasis. Brown fat is inversely related to body mass index and is associated with a lower probability of developing diabetes. Beige adipose tissue shares some functional characteristics with brown adipose tissue. White adipose tissue constitutes the majority of the fatty tissue and is mainly distributed in the subcutaneous and abdominal cavity. Intra-abdominal white fat has gained prominence in recent years for its association with cardiovascular risk factors and higher cardiovascular mortality. This review article discusses the human adaptation in the environment, a sympathovagal and hypothalamic-pituitary-adrenal imbalance as a possible cause of increased visceral adiposity and its consequences on cardiometabolism.

The Masses

A testicular yolk sac carcinoma (YSCA) was diagnosed in a 28-day-old male Japanese black calf. Macroscopically, the abdominal cavity was filled with reddish gelatinous masses of various sizes. There were no testes in the scrotum or pelvic cavity. Histologically, the masses consisted of the tissues showing a variety of patterns; loose reticular network, pseudopapillary arrangement, festoon, solid nest, and labyrinthine pattern. Tumor cells were round to oval, with single central or polar nuclei with sharply defined nuclear borders and deeply basophilic chromatin. Tumor cells sometimes had glycogen granules, periodic acid–Schiff (PAS)-positive inclusions, or sudanophilic droplets in their cytoplasm. Hyaline matrices were found in extracellular areas and were intensely PAS positive. Immunohistochemically, most of the tumor cells and hyaline matrices had positive reactivity to anti-alpha-fetoprotein and anti-placental-alkaline-phosphatase antibodies. Positive reaction to anti-laminin antibody appeared only in hyaline matrices. This is the first case of a tumor in a domestic animal with histologic and immunohistochemical features analogous to those of human YSCA, endodermal sinus type.

Abstract Objecitve: To investigate the feasibility ofxenotransplant leukemia model using by zebrafish, and lay the foundation for the study of acute myeloid leukemia and the screening of the drugs for targeting therapy of acute myeloid leukemia. Methods: Acute myeloid leukemia cell line KG1a was labeled with red fluorescent dye-MitoRed, then, the labeled cells was injected into the yolk sac of zebrafish embryos. Morphology observation, cell counting and histopathological detection were used to analysis the infiltration and metastasis of KG-1a cells in zebrafish. Results: KG1a cells could proliferate and gradually spread to the entire abdominal cavity of the zebrafish After KG1a cells were injected into the yolk sac during 1-7 dpi, the results of cell counting in vitro also proved a signification proliferation of KG1a cells in zebrafish, suggesting that the implanted leukemia stem cells could survive, proliferate and spread in zebrafish. Further study detected the implanted cells could transfered to the liver of zebrafish, these cells showed the signature of KG1a cells by hematoxy -lin -eosin(HE) staining. Conclusions: Human acute myeloid leukemia cells KG1a could survive, proliferate and migrate in zebrafish, suggesting xenotransplant leukemia model using by zebrafish is feasible. This model may provide benefit for the study of acute myeloid leukemia and the screening of the drugs for targeting therapy of acute myeloid leukemia.
