Guanylyl cyclase C (GC-C) is a member of a family of enzymes that metabolize GTP to cGMP and was first identified as a receptor for heat-stable enterotoxin. Guanylin (GNY) has since been identified as an endogenous ligand for GC-C in the intestine of several mammalian species. The GNY/GC-C system regulates ion transportation and pH in the mucosa. Recently, it was reported that GC-C and GNY are involved in lipid metabolism in rat mesenteric adipose tissue macrophages. To examine the role of GC-C and GNY in lipid metabolism in cattle, we used a bovine mesenteric adipocyte primary culture system and a coculture system for bovine adipocytes and GNY-/GC-C-expressing macrophages. Fat droplets were observed to accumulate in bovine mesenteric adipocytes cultured alone, whereas few fat droplets accumulated in adipocytes indirectly cocultured with macrophages. We also observed that GC-C was present in bovine mesenteric adipose tissue, and that fat droplet accumulation decreased after in vitro GNY ...

N2 - The examination of lymph nodes in colorectal cancer is a critical procedure for determining the stage, which determines prognosis and need for adjuvant therapy. The current recommendation is to harvest at least 12 lymph nodes by conventional manual node dissection (MND). Recent studies have suggested that all lymph nodes in mesenteric tissue should be retrieved using a special method such as the entire submission of residual mesenteric tissue (ESMT) after MND. We investigated the efficacy of ESMT with its potential impact on the pN stage. After an MND in 48 consecutive ...

Below the level of the upper part of the duodenum the ventral mensentery is wanting; only the dorsal mesentery occurs. So long as the intestine is a straight tube the length of the intestinal edge of this mesentery is practically equal to that of its dorsal attached edge. The intestine, however, increasing in length much more rapidly than the abdominal walls, the intestinal edge of the mesentery soon becomes very much longer than the attached edge, and when the intestine grows out into the umbilical ccelom the mesentery accompanies it (Fig. 198). As the coils of the intestine develop, the intestinal edge of the mesentery is thrown, into corresponding folds, and on the return of the intestine to the abdominal cavity the mesentery is thrown into a somewhat funnel-like form by the twisting of the intestine to form its primary loop (Fig. 199). All that portion of the mesentery which is attached to the part of the intestine which will later become the jejunum, ileum, ascending and transverse colon, ...

Mesentery: Mesentery, a continuous folded band of membranous tissue (peritoneum) that is attached to the wall of the abdomen and encloses the viscera. In humans, the mesentery wraps around the pancreas and the small intestine and extends down around the colon and the upper portion of the rectum. One of its

Plasma membranes from pig mesenteric lymph-node lymphocytes contain a large number of polypeptide chains ranging in molecular weight from 20,000 to greater than 470,000, with a major component of 46,000. There are approx. 12-15 glycoproteins. The membranes contain immunoglobulin G, which comprises 0.6% of the total protein. Immunoglobulin M is also detected, but has not been accurately quantified for technical reasons. Possible origins of the membrane-associated immunoglobulin are briefly discussed. It is concluded that the immunoglobulin is probably associated with the plasma membrane in the intact cell.. ...

A 73-year-old man presented with gastrointestinal hemorrhage. After bleeding for three days and receiving 15 units of blood, he underwent a laparotomy. A mass of tumor was found in the root of the small bowel mesentery, which had eroded into the duodenojejunal flexure. Tumor was found encasing the superior mesenteric artery. He underwent resection of the tumor and the involved intestine. The tumour proved to be renal cell in origin - the patient had undergone a left nephrectomy 15 years earlier. He is alive and well three years later. The pathological specimen shows deposits of renal cell tumor in the mesentery of the jejunum ...

Mathematicians and biologists at Harvard explain why vertebrate intestines are so predictably loopy. Between conception and birth, the human gut grows more than two meters long, looping and coiling within the tiny abdomen. Within a given species, the developing vertebrate gut always loops into the same formationhowever, until now, it has not been clear why.. Using a combination of experimental observations, biological and biophysical manipulations, theory, and computation, researchers at Harvard have shown that a simple balance of forces determines the form of the gut.. The finding may shed light on how the gut has been able to evolve to accommodate changes in diet.. The interdisciplinary research, published in the August 4th issue of Nature, demonstrates that differences in growth rates between the gut tube and the neighboring mesenteric tissue force the tube to coil, regardless of the space constraints.. One might think that the gut tube coils because it is restricted by the size of the ...

The two mesothelial layers are separated by a thick layer of mesodermal cells in which blood and lymph vessels to the gut and their derivatives develop. Nerves also reach these structures through the mesentery. The splenic primordium originates from the mesodermal cells in the dorsal mesentery in the region of the primitive stomach. The mesentery is named according to the structure it suspends (e.g., mesoesophagus, mesogastrium and mesoduodenum ...

Idiopathic sclerosing mesenteritis (ISM) or mesenteric panniculitus is a rare disease of the small intestine, characterized by chronic inflammation and eventual fibrosis of the mesentery. It has also been called mesenteric lipodystrophy, or retractile mesenteritis. Sclerosing mesenteritis may present with no or nearly no signs or symptoms, but many people have chronic and severe pain in the abdomen as the most common chief complaint. Other people have chronic problems with bowel movements, resulting in diarrhea, bloating, gas, and cramping which can range from severe to mild. The disorder is identified by histopathology showing fat necrosis, fibrosis and chronic inflammation of the small intestine. Examination of the mesentery may indicate a solitary mass, but diffuse mesentery thickening is common. It often mimics other abdominal diseases such as pancreatic or disseminated cancer. CT scanning is important for making the initial diagnosis. Several causes of sclerosing mesenteritis have been ...

Background Diet plays a role on the development of the immune system, and polyunsaturated fatty acids can modulate the expression of a variety of genes. Human milk contains conjugated linoleic acid (CLA), a fatty acid that seems to contribute to immune development. Indeed, recent studies carried out in our group in suckling animals have shown that the immune function is enhanced after feeding them with an 80:20 isomer mix composed of c9,t11 and t10,c12 CLA. However, little work has been done on the effects of CLA on gene expression, and even less regarding immune system development in early life. Results The expression profile of mesenteric lymph nodes from animals supplemented with CLA during gestation and suckling through dams milk (Group A) or by oral gavage (Group B), supplemented just during suckling (Group C) and control animals (Group D) was determined with the aid of the specific GeneChip® Rat Genome 230 2.0 (Affymettrix). Bioinformatics analyses were performed using the GeneSpring GX ...

Sclerosing mesenteritis (SM) is sometimes used as an umbrella-term for idiopathic inflammatory conditions in the mesentery. Mesenteric panniculitis (MP) is a radiological finding and its relation to clinical SM is not fully understood. The aims of this study were to determine whether any correlation could be found between the radiological findings and the clinical disease course. Patients observed due to idiopathic inflammation of the mesentery were identified. If SM could be verified histologically or MP radiologically, the patients were included in this descriptive retro perspective study. Typical radiological changes were observed in 27 patients. A majority (23/27) of these patients had mild to moderate symptoms. This group with typical radiology was labelled MP. Four patients were included due to histologically verified disease but had uncharacteristic radiology involving multiple compartments of the abdomen. All four had marked systemic inflammation, fever and fluctuating radiologic findings. Three

In the present study, to investigate diagnosis and treatment of strangulated intestinal obstruction caused by mesentery vein thrombosis on account of portal hypertension, the data in twelve patients with this disease from 1998 to 2008 were analyzed. All patients presented abdominal pain and vomiting and were confirmed strangulated intestinal obstruction caused by mesentery thrombosis with operation. In this group, nine patients underwent part of small intestine excision, and three patients underwent open-closed operation because of the whole small intestine necrosis caused by intensive mesentery thrombosis. Five patients died after operation. The diagnosis of strangulated intestinal obstruction caused by mesentery thrombosis was difficult because of the slow disease processes and severe outcomes. It is necessary to take some measures to get over the dangers duration after operation.

Summary. Mesenteric panniculits, also known as sclerosing mesenteritis, belongs to a spectrum of rare diseases of the fatty (adipose) tissue of the mesentery. Mesenteric panniculitis is characterized by fat degeneration and necrosis, chronic inflammation, and at times, scarring and fibrosis of fatty tissue within the mesentery. This inflammatory and at times progressive condition is most likely on the spectrum of autoimmune disorders.. The mesentery is a fold of tissue within the peritoneum that supports and attaches the small and large intestines to the walls of the abdomen. The mesentery contains fat, blood vessels, lymphatic tissue, lymphatic vessels and other forms of connective tissue. The peritoneum is a membrane that lines the abdominal cavity and covers the abdominal organs. The mesentery of the small intestine is most often affected in mesenteric panniculitis. Although the exact cause of mesenteric panniculitis remains unknown, the disease has been associated with a variety of other ...

Continuum models of the lymphatic system are scarce. As mentioned previously, Macdonald et al. [45] refined Reddys mathematical model by including two terms in the transmural pressure equation: a tension term and a damping term. Moreover, spatial averages of the pressure were not assumed, thus retaining the continuum nature of the governing equations. Two notable differences are that the contraction of the vessel wall was modelled by a change in Youngs modulus rather than an active stress added to the stress state of the material, and it was assumed that lymphangions do not have a refractory period, as in the work by Reddy et al. [75]. Data for parameters such as the Young modulus and damping were derived by experiments on bovine mesenteric lymphatics, although the properties measured had a very large variation owing to uncertainties in vessel diameter and wall thickness measurements.4 The Young modulus was found to be 1.2 ± 0.7 kPa; a quite large variation, possibly even larger than the ...

Cytokines (IL-6, IL-10 and TNF-α) are increased after exhaustive exercise in the rat retroperitoneal (RPAT) and mesenteric adipose tissue (MEAT) pads. On the other hand, these cytokines show decreased expression in these depots in response to a chronic exercise protocol. However, the effect of exercise with overload combined with a short recovery period on pro- and anti-inflammatory cytokine expression is unknown. In the present study, we investigated the regulation of cytokine production in the adipose tissue of rats after an overtraining-inducing exercise protocol. Male Wistar rats were divided into four groups: Control (C), Trained (Tr), Overtrained (OT) and recovered overtrained (R). Cytokines (IL-6, TNF-α and IL-10) levels and Toll Like Receptor 4 (TLR4), Nuclear Factor kBp65 (NF-kBp65), Hormone Sensitive Lipase (HSL) and, Perilipin protein expression were assessed in the adipose tissue. Furthermore, we analysed plasma lipid profile, insulin, testosterone, corticosterone and endotoxin levels, and

IL-17-expressing CD4+ T lymphocytes (Th17 cells) naturally reside in the intestine where specific cytokines and microbiota, such as segmented filamentous bacteria (SFB), promote their differentiation. Intestinal Th17 cells are thought to initially differentiate in the GALT and/or mesenteric lymph nodes upon Ag encounter and subsequently home to the lamina propria (LP) where they mediate effector functions. However, whether GALT and/or mesenteric lymph nodes are required for intestinal Th17 differentiation as well as how microbiota containing SFB regulate Ag-specific intestinal Th17 cells remain poorly defined. In this study, we observed that naive CD4+ T cells were abundant in the intestinal LP prior to weaning and that the accumulation of Th17 cells in response to microbiota containing SFB occurred in the absence of lymphotoxin-dependent lymphoid structures and the spleen. Furthermore, the differentiation of intestinal Th17 cells in the presence of microbiota containing SFB was dependent on MHC ...

Immune tissues are known to be innervated by the sympathetic nervous system, but little is known of what directs the innervation to specific tissue compartments. This report examines the sympathetic innervation of immune tissues in transgenic mice that overexpress nerve growth factor (NGF) in skin and other epithelial structures. NGF transgenic mice exhibited dramatic hyperinnervation in the splenic marginal zone, and the medulla and capsule of peripheral lymph nodes. In contrast, the transgenic mesenteric lymph nodes showed no hyperinnervation. This difference correlated with the location of these nodes; peripheral lymph nodes drain skin where the transgene was expressed while mesenteric lymph nodes drain non-transgene-expressing structures. In addition, the level of innervation correlated with the level of NGF peptide content as assayed by ELISA (3- and 13-fold increase in transgenic spleen and axillary lymph nodes, respectively; no increase in mesenteric nodes) and immunocytochemistry. RT-PCR ...

Protein kinase G (PKG) is activated by nitric oxide (NO)-induced cGMP binding or alternatively by oxidant-induced interprotein disulfide formation. We found preactivation with cGMP attenuated PKG oxidation. 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) blockade of cGMP production increased disulfide PKG to 13±2% and 29±4% of total in aorta and mesenteries, respectively. This was potentially anomalous, because we observed 2.7-fold higher NO levels in aorta than mesenteries; consequently, we had anticipated that ODQ would induce more disulfide in the conduit vessel. ODQ also constricted aorta, whereas it had no effect on mesenteries. Thus, mesenteries, but not aorta, can compensate for loss of NO-cGMP by recruiting disulfide activation of PKG. Mechanistically, this is explained by loss of cGMP allowing disulfide formation in response to basal oxidant production. Why aorta treated with ODQ generated less PKG disulfide that is insufficient to induce vasoconstriction was unclear. One potential ...
