RESUMEN
Accompanied by the rapid growth of the global population and increasing public awareness of protein-rich foods, the market demand for protein-derived products is booming. Utilizing available technologies to make full use of meat by-products, such as scraps, trimmings, etc., to produce restructured meat products and explore emerging proteins to produce meat analogues can be conducive to alleviating the pressure on supply ends of the market. The present review summarizes diversified techniques (such as high-pressure processing, ultrasonic treatment, edible polysaccharides modification, enzymatic restructuring, etc.) that have been involved in restructuring meat protein-derived products as well as preparing meat analogues identified so far and classifying them into three main categories (physical, chemical and enzymatic). The target systems, processing conditions, effects, advantages, etc., of the included techniques, are comprehensively and systemically summarized and discussed, and their existing problems or developing trends are also briefly prospected. It can be concluded that a better quality of restructured products can be obtained by the combination of different restructuring technologies. This review provides a valuable reference both for the research and industrial production of restructured meat protein-derived products and analogues.
RESUMEN
BACKGROUND AND OBJECTIVES: As a well-known phenomenon with significant social, biological, and psychological impacts, burnout syndrome has been viewed and treated from different therapeutic perspectives. However, few studies have evaluated interventions to prevent and alleviate teacher burnout. DESIGN: This study comprised a randomized controlled trial (RCT) of a group-based cognitive-behavioral therapy (CBT) program for teacher burnout, with assessments at pre-treatment, post-treatment, and 6-month follow-up. METHODS: The Maslach Burnout Inventory-Educators Survey (MBI-ES) was administered to 242 English language teachers with diverse professional profiles in Iran. Of these, 62 teachers with burnout symptoms were randomly assigned to either a group-based eight-week CBT treatment program or a waiting list control condition. RESULTS: The results of a series of mixed factorial ANOVAs demonstrated significantly greater improvements for the treatment compared to the control condition on the total score and three subscales of the MBI-ES (teachers' emotional exhaustion, depersonalization, and reduced personal accomplishment) at post-treatment, with treatment effects maintained at 6-month follow-up. CONCLUSIONS: This CBT intervention has promise for supporting teachers in stressful occupational conditions and reducing their burnout.
