D-aspartate stimulates growth hormone secretion in wethers.

Growth hormone (GH) is an essential factor in enhancing the productivity of animals. In ruminants, L-aspartate (L-Asp) stimulates the secretion of GH; however, the effect of D-Asp on GH remains unknown. Here, we examined the effect of D-Asp on GH secretion in wethers.

Impact of the endoscopic surgical skill qualification system on conversion to laparotomy after low anterior resection for rectal cancer in Japan (a secondary analysis of the EnSSURE study).

Background And Aims: Conversion to laparotomy is among the serious intraoperative complications and carries an increased risk of postoperative complications. In this cohort study, we investigated whether or not the Endoscopic Surgical Skill Qualification System (ESSQS) affects the conversion rate among patients undergoing laparoscopic surgery for rectal cancer.

Methods: We performed a retrospective secondary analysis of data collected from patients undergoing laparoscopic surgery for cStage II and III rectal cancer from 2014 to 2016 across 56 institutions affiliated with the Japan Society of Laparoscopic Colorectal Surgery.

Development of active jejunal glucose absorption in broiler chickens.

Growth in chickens, especially meat-type chickens (broilers), is extremely rapid, but studies on the regulatory mechanism of intestinal glucose absorption with growth are few, contradictory, and unclear. Here, we investigated the regulation of intestinal glucose absorption with growth in broiler chickens using oral glucose gavage, intestinal Evans blue transit, intestinal glucose absorption, scanning electron microscopy, and glucose absorption- and cell junction-related gene expression analyses. Peak blood glucose levels after oral glucose gavage occurred at 10 and 50 min in chickens at 1 wk (C1W) and 5 wk (C5W) of age, respectively.

Circadian rhythm in hypothalamic leptin receptor (Ob-Rb) mRNA expressions and cerebrospinal fluid and circulating glucose and leptin levels in lactating rats.

In lactating animals, the food consumption increases several-fold for milk supply to the pups. The present study was conducted to clarify the relationship between the hyperphagia during lactation and hypothalamic leptin receptor (Ob-Rb) mRNA expression, cerebrospinal fluid (CSF) and circulating leptin and glucose levels. Food intakes significantly higher in lactation than in non-lactation at all time points (3 points: light phase, 4 points: dark phase) of the day.

[Case of Gastric Malignant Lymphoma Invading Other Organs with Bleeding Treated by Surgery].

A female in her late 50s experienced dyspnea and was transported by an ambulance. Her hemoglobin score was low, and CT imaging showed a giant tumor in her stomach. The tumor perforated her liver and invaded the abdominal wall and duodenum around the Treitz ligament.

Age-related Regulation of Active Amino Acid Transport in the Ileum of Broiler Chickens.

Broiler chickens grow rapidly within a short period; in this regard, our group had previously reported a decrease in the active transport of glucose in the intestines of broiler chickens with their growth. Therefore, in this study, we compared the active transport process of amino acids in the intestines between 1- and 5-week-old broilers using everted sac, Ussing chamber techniques, and real-time quantitative polymerase chain reaction (RT-PCR). The everted sac experiment showed that amino acids were absorbed from all segments of the small intestine in both age groups.

Advanced treatment technique for swine wastewater using two agents: Thermally polymerized amorphous silica and hydrated lime for color and phosphorus removal and sulfur for nitrogen removal.

The efficacy of advanced treatment of swine wastewater using thermally polymerized, modified amorphous silica and hydrated lime (M-CSH-lime) for color and phosphorus removal and sulfur for nitrogen removal was examined with a demonstration-scale treatment plant. The color removal rate was approximately 78% at M-CSH-lime addition rates of > 0.055 wt/v%.

"Hook and roll technique" using an articulating hook cautery to provide a critical view during single-incision laparoscopic cholecystectomy.

We describe a new simple and easy technique called the "Hook and roll technique" (HRT) that uses an articulating hook cautery to provide a critical view during single incision laparoscopic cholecystectomy (SILC). A 2-cm incision is made at the umbilicus to insert three 5-mm trocars or a multichannel port. After dissection of the serosa of the dorsal and ventral sides of the gall bladder, including Calot's triangle, the angled tip of the hook cautery is inserted between the cystic artery and duct with its tip placed dorsally.

The mechanism underlying the central glucagon-induced hyperglycemia and anorexia in chicks.

We investigated the mechanism underlying central glucagon-induced hyperglycemia and anorexia in chicks. Male 8-day-old chicks (Gallus gallus) were used in all experiments. Intracerebroventricular administration of glucagon in chicks induced hyperglycemia and anorexia from 30 min after administration.

Hormonal differences in peripheral blood and gene profiling in the liver and lymphocytes in Japanese black cattle with growth retardation.

Japanese Black cattle occasionally demonstrate growth retardation despite sufficient nutrient intake. To clarify hormonal and transcriptional characteristics, we investigated differences in blood components, including hormones, and differences in exhaustive gene expressions in the liver and peripheral lymphocytes of six cattle with growth retardation (GR cattle) and eight control cattle of the same age and pedigree with normal growth. Hematocrit values and concentrations of hemoglobin, serum albumin, total cholesterol, insulin-like growth factor 1 (IGF-1), thyroxine and insulin in GR cattle were significantly lower than those in controls.

[A case of duodenal gastrointestinal stromal tumor treated by pancreas-sparing partial duodenectomy].

An 79-year-old man admitted our hospital for abdominal mass. Computed tomography showed a tumor measuring about 10 cm in diameter without any metastasis lesion and any sings of local infiltration. Gastroduodenal endoscopy revealed the presence of a submucosal tumor in the third portion of the duodenum, and biopsy revealed tumor cells stained positive for c-kit.

[A long-term survival case of bilateral ovarian metastasis of progressive gastric cancer treated by chemotherapy].

We report a long-term survival case treated by chemotherapy with new anticancer drugs such as S-1, CPT-11 and docetaxel after bilateral overiectomy for bilateral ovarian metastases of progressive gastric cancer. A 68-year-old female, who had undergone total gastrectomy with D2 lymphadenectomy for scirrhous gastric cancer of Stage IIIA, was admitted because of ovarian metastasis. Laparoscopic bilateral ovariectomy was performed for ovarian metastases of the gastric cancer (Krukenberg tumor) 6 months after gastrectomy.

The differences in feeding-inhibitory responses to peripheral and central leptin between non-lactating and lactating rats.

This study was conducted to examine the contributions of central and peripheral leptin to hyperphagia in lactation. Lactating rats were mated at 7-8 weeks of age and housed singly with their litters. In experiment 1, food intakes were significantly (P<0.

Effects of central administration of glucagon on feed intake and endocrine responses in sheep.

This study was conducted to investigate effects of glucagon intracerebroventricularly administered on feed intake and endocrine changes in sheep. Four male sheep (48-55 kg BW) were used. The animals were acclimatized to be fed alfalfa hay cubes at 12.

Ghrelin differentially modulates glucose-induced insulin secretion according to feeding status in sheep.

The present study was conducted to investigate roles of ghrelin in glucose-induced insulin secretion in fasting- and meal-fed state in sheep. Castrated Suffolk rams were fed a maintenance diet of alfalfa hay cubes once a day. Hyperglycemic clamp (HGC) was carried out to examine glucose-induced insulin response from 48 to 53 h (fasting state) and from 3 to 8 h (meal-fed state) after feeding in Experiment 1 and 2 respectively.

New laparoscopic double-stapling technique.

Background: Laparoscopic surgery for colon cancer has been shown by several randomized, controlled trials to be an acceptable alternative to open surgery; however, laparoscopic rectal surgery has not been evaluated in a randomized trial. One of the most serious problems associated with laparoscopic rectal surgery are bowel clamping, irrigation, and transection of the rectum, and laparoscopic rectal surgery has not been as reliable as open rectal surgery.

Materials And Methods: We present our new technique, the laparoscopic double-stapling technique, which eliminates these problems.

Central administration of glucagon suppresses food intake in chicks.

Food intake in chickens is regulated in a manner similar to that in mammals. Corticotropin-releasing factor (CRF), which increases the plasma corticosterone concentration, plays an important role as a mediator of many appetite-suppressive peptides in the central nervous system in both species. Central administration of glucagon suppresses food intake in rats.

Effects of central infusion of ghrelin on food intake and plasma levels of growth hormone, luteinizing hormone, prolactin, and cortisol secretion in sheep.

Ghrelin is an endogenous ligand for the GH secretagogue/ghrelin receptor (GHS-R) and stimulates feeding behavior and GH levels in rodents and humans. A preprandial increase in plasma ghrelin levels is seen in sheep on programmed feeding, followed by a postprandial rise in plasma GH levels, but effects on food intake and endocrine function are not defined in this ruminant species. We administered ghrelin to female sheep in various modes and measured effects on voluntary food intake (VFI) and plasma levels of GH, LH, prolactin, and cortisol.

Involvement of cholinergic neurons in the regulation of the ghrelin secretory response to feeding in sheep.

We previously demonstrated that a transient surge in plasma levels of ghrelin occurs just prior to a scheduled meal and that this surge is modified by the feeding regimen. This suggests that the ghrelin secretion is regulated by the autonomic nervous system, especially the cholinergic projections to the stomach. To test this hypothesis, we investigated changes in plasma ghrelin levels at feeding time in rams by administering cholinergic blockers (atropine and hexamethonium) and a cholinergic accelerator (metoclopramide).
