This study investigated the effects of highland barley’s germination time(24,48,and 72 h)on the thermomechanical,pasting,fermentation,dynamic rheological,molecular mobility,and protein structural properties of oat-wheat composite flour *** significantly reduced flour water absorption,freezable water,melting enthalpy,and increased protein weakening compared with native barley(NB)*** addition,germination decreased bound and immobilized water and increased the free water compared to the NB-composite flour dough samples,according to the results of a low-field nuclear magnetic resonance spectrometer(LF-NMR).Germination also increased the protein’s extractability and surface hydrophobicity while negatively impacting the starch-protein network;however,it decreased bread-specific *** for 24 h,on the other hand,had minor effects on dough and bread samples compared to 48 and 72 *** a result,germination for 24 h under controlled conditions could be used to improve the rheological qualities of highland barley and avoid the adverse rheological effects of the prolonged germination period.

Long-term Consumption of Highland Barley Tea Promotes Healthy Aging of Skeletal Muscle

引用

Food Science and Human Wellness 2024年

作者： Li Yan Chenzhipeng Nie Qingwei Zheng Mingcong Fan waleed al-ansi Haifeng Qian Li Wang State Key Laboratory of Food Science and Technology， School of Food Science and Technology， Jiangnan University

Highland barley tea (HBT) is made from roasted barley seeds and is abundant in β-glucan， amino acids， minerals， phenolics， and other natural active ingredients. These natural compounds found in whole grains have been shown to slow aging and positively affect skeletal muscle function. As a result， studying the effects of HBT on the skeletal muscle health of the elderly population is critical from a scientific and societal standpoint for improving their health status and reducing the medical burden on society. The antioxidant activity and the content of natural active substances were used as indicators to screen the optimal process of HBT brewing. The effects of long-term HBT consumption on aging in mice were investigated by using HBT as a substitute for drinking water in naturally aging mice for a 5-month intervention. Afterward， various factors were measured， such as basic physiological indices， inflammation， plasma metabolites， skeletal muscle function， and exercise capacity， to evaluate the effects of HBT on aging in mice. Long-term consumption of HBT reduced body and spleen weight， increased body weight percentage of skeletal muscle， and reduced plasma inflammation levels in aging mice. Metabolomic results showed increased plasma levels of the mitochondrial marker short-chain acylcarnitine and some amino acids. Additionally， there was a decrease in bile and long-chain acylcarnitine. The level of fibrosis in the gastrocnemius muscle of aging mice was suppressed， and the percentage of type I muscle fibers was increased， improving the endurance of the mice. Thus， long-term consumption of HBT may reduce body weight and increase skeletal muscle mitochondrial activity and exercise capacity in aging mice by reducing inflammation levels and alleviating mitochondrial damage.

Severe autoimmune hepatitis triggered by varicella zoster infection

引用

World Journal of Gastroenterology 2009年第8期15卷 1004-1006页

作者： waleed K al-Hamoudi Gastroenterology and Hepatology Unit (59) Department of Medicine King Saud University PO Box 2925 Riyadh 11461 Saudi Arabia

Autoimmune hepatitis (AIH) is a chronic disease of unknown etiology that is characterized by the presence of circulatory autoantibodies and inflammatory histological changes in the liver. although the pathogenesis of AIH is not known, it is thought that, in a genetically predisposed individual, environmental factors such as viruses can trigger the autoimmune process. Herpes simplex virus, Epstein-Barr virus, measles virus, and hepatitis viruses are thought to play a role in the etiology of AIH. Proteins belonging to these viruses may be similar to the amino acid chains of different autoantigens in the liver, this causes immune cross reactions and liver tissue damage. We report a case of severe AIH following varicella zoster infection in a 23-year-old man, and speculate that, based on the molecular mimicry hypothesis, the liver damage was caused by an immune cross reaction to the viral proteins. Varicella-zoster-induced AIH has not been reported previously.

Let D be the open unit disk in the complex plane C. For a〉 -1, let dAa（z）=（1 ＋a）（1 -｜z}^2） ^a da（z）be the weighted Lebesgue measure on ]D. For a positive function ω ∈ L^1（D,dAa）, the generalized weighted Bergman-Orlicz spaceA^ψω（D,dAa）is｜｜f｜｜ω^ψ=∫Dψ｜F（z）｜ω（z）dA^（z）〈 ∞,where q; is a strictly convex Orlicz function that satisfies other technical hypotheses. Let G be a measurable subset of D, we say G satisfies the reverse Carleson condition for A^ψω （D, dAa） if there exists a positive constant C such that ∫Gψ（f（z））ω（z）dAa（z）≥C∫Dψ（｜f（z）dAa（z）.for all f ∈ .A^ψω （D,dAa）. Let μ be a positive Borel measure, we say μ satisfies the direct Carleson condition if there exists a positive constant M such that for all f∈Aψ^ω （D,dAa）,∫Dψ（｜f（z）｜）dμ（z）≤M∫Dψ（｜f（z）｜）ω（z）dAa（a）.In this paper, we study the direct and reverse Carleson condition on the generalized weighted Bergman-Orlicz space Aω^ψ（D,dAa）.We present conditions on the set G such that＇the reverse Carleson condition＇holds. ＂Moreover, we give a sufficient condition for the finite positive Borel measure μ to satisfy the direct carleson condition on the generalized weighted Bergman-Orlicz spaces.
