The influence of giant fibres on utility for production of massaged products of porcine muscle longissimus dorsi

Musculus longissimus dorsi (L) originating from 6 genotype groups of pigs was examined. Three among these were parental lines: Pietrain (Pi), Duroc (D), Polish Large White × Polish Landrace (PLW × PL), the other three crossbreeds obtained by crossing the aforementioned parental lines: (PLW × PL) × Pi, (PLW × PL) × (Pi × D) and (PLW × PL) × (D × Pi). It was found that there exists a variety of numbers and sizes of giant fibres and sizes of muscle fibres in the L muscle of the groups of animals, which results in a diversity of quality and susceptibility to massaging. The largest number of giant fibres and the greatest sizes of normal and giant fibres, along with the largest losses after heat treatment, the highest hardness, shear force, the lowest juiciness and attractiveness were found in the L muscle of Pi. Muscle of this breed was characterised by the least change in quality indicators during massaging. The decrease of Pi breed genes in the crossbreed genotype, resulted in reduction in the quantity of giant fibres and fibre sizes in comparison with pure Pi breed, which increased quality of crossbreeds’ muscles and their susceptibility to massaging.     

A review of meat protein hydrolysates and hypertension

We tested the hypothesis that meat is a source of peptides that are effective at preventing and reducing chronic lifestyle-related diseases (CLSRDs) such as hypertension. This analysis reflects the importance of empowering hypertensive people in quality versus quantity of life issues, and in offering nutritional treatment options rather than medical alternatives. For both hypertensive and normotensive individuals, chemically based medications may have harmful side effects. Functional food rich in antioxidant vitamins, and proteins or biologically active peptides, can lower blood pressure in persons with essential hypertension, possibly by preventing an underlying cause of the condition. Deficiency in consumption of crucial nutrients such as proteins from meat origins, along with abnormalities in carbohydrate and fat metabolism, may underlie the etiology of the clinical course of hypertension. Food derived from meat rich in nutrients may provide physiologically functional peptides, as well as improve digestion, and the metabolism of carbohydrate and fats, thus lowering blood pressure, and normalizing associated biochemical and histopathological changes.     

鱼类保活运输及其对肌肉和血液生理生化指标影响研究进展

随着水产品冷链物流技术的发展,作为其重要组成部分,保活运输的关键点已不仅是成活率和生理生化指标,运输过程对水产动物营养和品质的影响也至关重要.本文通过综述不同鱼类在有水保活和无水保活运输方法下,运输条件对鱼肉蛋白质、脂肪、糖原、pH的影响机制以及保活运输前后鱼体内主要生理生化指标的变化,发现温度对保活运输鱼类存活的影响...     

针刺运动疗法、温针灸结合康复治疗中风后上肢肌痉挛30例

摘 要:目的 探讨针刺运动疗法、温针灸结合康复治疗改善中风后患侧上肢肌痉挛的临床疗效。方法 将60例中风后上肢肌痉挛的患者按随机数字表法分为对照组与治疗组。对照组以常规针刺和康复治疗;治疗组给予温针灸、针刺运动疗法和康复治疗,观察两组患者治疗前后患侧上肢肌痉挛程度改善情况,比较两组患者治疗前后MAS、FMMS、ADL评分。结果 经治疗,治疗组总有效率为90%,对照组总有效率为80%,差异有统计学意义（P<0.05）;治疗后,两组患者患侧上肢痉挛程度、MAS、FMMS、ADL量表评分较治疗前均有改善,且治疗组疗效明显高于对照组（P<0.05）。结论 针刺运动疗法、温针灸结合康复治疗能有效降低中风患者患侧上肢肌张力,改善肢体运动功能,促进日常生活能力的恢复。     

辅助老年人行走的智能安全内衣设计

为设计一款辅助老年人行走的智能安全内衣,首先应用模糊理论对50名60~80岁的行走不便的老年人进行调研,确定智能安全内衣的4个设计要素,包括尺寸合体、面料安全、智能元件、造型款式与工艺。阐述智能电子肌肉元件的设计原理,并结合人体工程学和中医学,确定辅助老年人行走及减轻腰腿疼痛的关键部位。然后采用嵌入式工艺将柔性智能电子肌肉元件置于人体阔背肌、髋骨肌、臀中肌、股四头肌部位,并从时尚性、安全性、智能性相结合的角度,介绍辅助老年人行走的智能安全内衣的款式设计、色彩设计和面料设计。设计开发的智能安全内衣具有增强肌肉紧度、促进血液流通、提高直立和行走稳定性的功能,而且美观、安全、舒适。
