Acute pancreatitis (AP) is an inflammatory disease presenting from mild localized inflammation to severe infected necrotic pancreatic tissue. In the literature, there are a few cases of hypothermia-induced AP. However, the association between hypothermia and AP is still a myth. Generally, mortality from acute pancreatitis is nearly 3-6%. Here, we present a 40-year-old chronic alcoholic female who presented with acute pancreatitis induced by transient hypothermia. A 40-year-old chronic alcoholic female was hypothermic at 81°F on arrival which was improved to 91...

BACKGROUND: Measurement standardization of the catalytic concentration of α-amylase in serum is based on 3 pillars: the primary reference measurement procedure (PRMP), reference laboratories, and suitable certified reference materials (CRMs). Commutability is a prerequisite when using a CRM for calibration and trueness control of routine methods or for value transfer from the PRMP to end-user calibrators of routine methods through a calibration hierarchy. METHODS: We performed a commutability study with 30 serum pools and 5 candidate reference materials (RMs) for pancreatic α-amylase using an automated version of the PRMP and 5 different routine methods...

José R Valverde, Sonia Gullón, Rafael P Mellado
BACKGROUND: Streptomyces lividans has demonstrated its value as an efficient host for protein production due to its ability to secrete functional proteins directly to the media. Secretory proteins that use the major Sec route need to be properly folded outside the cell, whereas secretory proteins using the Tat route appear outside the cell correctly folded. This feature makes the Tat system very attractive for the production of natural or engineered Tat secretory proteins. S. lividans cells are known to respond differently to overproduction and secretion of Tat versus Sec proteins...

Plant proteins are often characterized by low solubilities and impaired functionalities e.g. emulsifying properties. In products like milk substitutes, these protein properties are of great importance to ensure good product quality. In this study proteolytic enzymes were used as a tool to increase protein solubility and alter their properties gently. A plant-based milk substitute based on quinoa was produced and treated with different enzymes. One α-amylase and three commercial proteases were selected: Hitempase 2XP, Profix 100L, Bioprotease N100L, and Flavourzyme 1000L...

Nano-fibrillated cellulose (NFC) is of interest in several fields due to its unique physical properties derived from its nanoscale dimensions. NFC has potential use in food systems as a dietary fiber that increases viscosity and limit diffusion of glucose. This study focused on the effects of added NFC on solution viscosity, starch digestion and glucose absorption. NFC did not affect α-amylase and α-glucosidase activity, but significantly retarded glucose diffusion, delayed amylolysis and reduced the amount of glucose released during in vitro digestion of starch...

Acute pancreatitis (AP) is a common acute abdominal disease accompanied by systemic inflammatory response syndrome, and could even be complicated by multiple-organ damage. This study aimed to examine whether calycosin, an isoflavone isolated from Radix astragali with antioxidant and anti-inflammatory activity, could protect against AP induced by cerulein. To this end, Balb/C mice were injected with cerulein (50 μg/kg) to establish the animal model of AP. Calycosin (25 and 50 mg/kg, p.o.) was administered 1 h prior to the first cerulein injection...

Naturally air-dried chestnut is a type of traditionally processed chestnut in North China which has a pleasant flavor. After air drying at room temperature and low-air humidity for two wk, the moisture, total starch content and starch relative crystallinity decreased, while the content of water-soluble sugar and amylose increased because of the dehydration and the hydrolysis of endogenous amylase. The Fourier transform infrared (FTIR) spectroscopy ratio of 1047/1022 cm-1 and the relative area of the Raman spectrum peak at 480/865 cm-1 of air-dried chestnut starch decreased in the first two wk and then increased, while the full width at half-maximum height (FWHH) of the Raman spectrum peak at 480 cm-1 showed the opposite tendency...
