Effects of konjac glucomannan as a freeze-denaturation inhibitor or binder on the physiochemical properties of heat-induced gel of freeze-dried duck blood.

During freeze-drying, the degradation or eutectic melting of duck blood proteins can reduce the quality of duck blood gels. However, the interaction between proteins and polysaccharides during drying can improve protein-based gel quality. Therefore, here, we investigated the physicochemical properties of heat-induced gels of freeze-dried duck blood (FDB) and FDB with different proportions of the polysaccharide konjac glucomannan (KG), which serves as a freeze-denaturation inhibitor agent (FDA) or binder (BG).

Ruptured Gastroduodenal Artery Pseudoaneurysms as a Complication of Pancreatitis.

Visceral artery pseudoaneurysms is a known vascular complication of pancreatitis that can lead to life-threatening hemorrhages with a high mortality rate if left untreated. We present a case of ruptured gastroduodenal artery pseudoaneurysm in a 68-year-old male with acute pancreatitis presenting with fatal gastrointestinal and retroperitoneal bleeding that was successfully managed with endovascular coil embolization of the involved vasculature. Patients with hemorrhagic pancreatitis or those presenting with unexplained retroperitoneal or gastrointestinal bleeding in the setting of pancreatitis with an unexplained drop in hematocrit or sudden expansion of pancreatic fluid collection should be screened in a timely manner for pseudoaneurysm using CT angiogram of the abdomen, which is the gold standard imaging modality to identify pseudoaneurysms.

When Meals Turn Into a Medical Mystery: A Case Report of Sigmoid Colon Impaction by a Chicken Bone.

The presence of foreign objects in the digestive system can lead to various complications within the gastrointestinal (GI) tract. In certain cases, ingesting foreign objects can pose a significant dilemma for surgical teams, primarily because they can lead to blockages or punctures in the upper or lower sections of the GI tract. On occasion, foreign objects located in the lower regions of the digestive tract, such as the colon and rectum, might have entered via the anal pathway, thereby carrying the potential risk of causing perforations in the rectum or sigmoid colon.

Healable Anti-Corrosive and Wear-Resistant Silicone-Oil-Impregnated Porous Oxide Layer of Aluminum Alloy by Plasma Electrolytic Oxidation.

Lubricant (or oil)-impregnated porous surface has been considered as a promising surface treatment to realize multifunctionality. In this study, silicone oil was impregnated into a hard porous oxide layer created by the plasma electrolytic oxidation (PEO) of aluminum (Al) alloys. The monolayer of polydimethylsiloxane (PDMS) from silicone oil is formed on a porous oxide layer; thus, a water-repellent slippery oil-impregnated surface is realized on Al alloy, showing a low contact angle hysteresis of less than 5°.

Astrocytic FoxO1 in the hypothalamus regulates metabolic homeostasis by coordinating neuropeptide Y neuron activity.

The forkhead box transcription factor O1 (FoxO1) is expressed ubiquitously throughout the central nervous system, including in astrocytes, the most prevalent glial cell type in the brain. While the role of FoxO1 in hypothalamic neurons in controlling food intake and energy balance is well-established, the contribution of astrocytic FoxO1 in regulating energy homeostasis has not yet been determined. In the current study, we demonstrate the essential role of hypothalamic astrocytic FoxO1 in maintaining normal neuronal activity in the hypothalamus and whole-body glucose metabolism.

Gastric Metastasis 5 Years after Primary Invasive Lobular Adenocarcinoma of the Breast.

Breast cancers metastasize most commonly to the bone, brain, liver, and lungs, but rarely to the gastrointestinal tract. Although metastatic breast carcinomas in the stomach can be confused with primary gastric cancers due to their nonspecific presentation and rare incidence, it is important to differentiate the two since the treatment is different. Clinical suspicion is imperative for a prompt endoscopic evaluation and a definitive diagnosis that will lead to appropriate treatment.

Development of meat spread with omega-3 fatty acids derived from flaxseed oil for the elderly: Physicochemical, textural, and rheological properties.
