Exercise training is now recognized as an interesting therapeutic strategy in managing obesity and its related disorders. However, there is still a lack of knowledge about its impact on obesity-induced chronic kidney disease (CKD). Here, we investigated the effects of a delayed protocol of endurance exercise training (EET) as well as the underlying mechanism in obese mice presenting CKD. Mice fed a high-fat diet (HFD) or a low-fat diet (LFD) for 12 weeks were subsequently submitted to an 8-weeks EET protocol. Delayed treatment with EET in obese mice prevented body weight gain associated with a reduced calorie intake. EET intervention counteracted obesity-related disorders including glucose intolerance, insulin resistance, dyslipidaemia and hepatic steatosis. Moreover, our data demonstrated for the first time the beneficial effects of EET on obesity-induced CKD as evidenced by an improvement of obesity-related glomerulopathy, tubulo-interstitial fibrosis, inflammation and oxidative stress. EET also prevented renal lipid depositions in the proximal tubule. These results were associated with an improvement of the AMPK pathway by EET in renal tissue. AMPK-mediated phosphorylation of ACC and ULK-1 were particularly enhanced leading to increased fatty acid oxidation and autophagy improvement with EET in obese mice. 相似文献

Advanced medical treatments involving drug delivery require fully biocompatible materials with the ability to release functional drugs in a time-prolonged way. Ideally, the delivered molecules should be self-contained as chemically homogenous entities to prevent the use of potentially toxic scaffolds or hold matrices. In nature, peptidic hormones are self-stored in protein-only secretory granules formed by the reversible coordination of Zn2+ and histidine residues. Inspired by this concept, an in vitro transversal procedure is developed, analyzed, and comparatively applied for the fabrication of protein-only secretory granules at the microscale. These materials can be produced from any polyhistidine-tagged protein using physiological concentrations of Zn2+ as a potent and versatile glue-like agent. The screening of granules formed by 12 engineered and nonengineered proteins at different Zn2+ concentrations revealed optimal fabrication conditions and the consequent release profiles. Moreover, the functional and structural properties of the delivered protein are fully validated using a drug-targeting protein platform in a mouse model of human colorectal cancer. In summary, short histidine tags allow the packaging of structurally and functionally dissimilar polypeptides, which supports the proposed fabrication method as a powerful protocol extensible to diverse clinical scenarios in which slow protein drug delivery is required. 相似文献

ABSTRACTThe relationship between gender and water, sanitation and hygiene (WASH) services is an issue for many developing states. This scoping review demonstrates that in Nepal, women bear the major social burden of inadequate WASH services and are under-represented in WASH-related policies and programmes. Four themes emerge: gender and water projects; lack of equal female participation in WASH policy development and implementation; women’s access to water; and menstruation and menstrual hygiene. Major cultural barriers embedded in Nepali society limit women’s access, agency and participation in WASH-related policy and practice. 相似文献

Assessment of Escherichia coli O157:H7-specific bacteriophages e11/2 and e4/1c in model broth and hide environments 总被引:1,自引:0,他引:1

The efficacy of bacteriophages e11/2 and e4/1c as potential biocontrol agents for Escherichia coli O157:H7 in food applications was assessed under conditions relevant to the food chain environment. The stability of each phage was determined following exposure to varying environmental conditions (pH, temperature, water activity, and sodium chloride) and the ability of each phage to infect and reduce E. coli O157:H7 numbers under selected conditions was also examined. Both e11/2 and e4/1c significantly (p < 0.05) reduced numbers of E. coli O157:H7 when exposed to pH values ranging from pH > 4 to pH 9, temperatures from 4 °C to 37 °C, water activity values of 0.87 or 0.91 to 1.00 and NaCl concentrations of 1% to 2.5%. Subsequently, a cocktail of both phages was used (e11/2 and e4/1c) to assess reduction of E. coli O157:H7 on cattle hide pieces. This involved inoculating pieces of hide (20 × 20 cm) with E. coli O157:H7 (approximately 106 cfu/cm2) which were subsequently treated with either a suspension of a phage cocktail, consisting of e11/2 and e4/1c (multiplicity of infection of 1000 and 10,000, respectively) or water or not treated. Two different investigations were carried out; immediately or 1 h after treatment application was performed in different experiments. Swab samples taken immediately after phage treatment showed no significant (p > 0.05) reduction of E. coli O157:H7 numbers compared to the water treated or untreated samples. However, an extended exposure time of 1 h following phage application revealed a significant reduction (p < 0.05) (1.5 log10 cfu/cm2 reduction) in E. coli O157:H7 numbers compared to the numbers recovered on samples treated with water only. These findings demonstrate the potential use of e11/2 and e4/1c phages as a biocontrol agent for E. coli O157:H7 within various stages of the food chain, including on cattle hide. 相似文献

Studied the proportion of therapy clients who report mystical experiences, the diagnostic attitudes of their therapists, and the influence of personal and professional factors on attitudes toward these clients by analyzing the survey responses of 285 32–82 yr old psychotherapists (primarily males). Of the 20,670 clients seen during a 12-mo period, 4.5% reported a mystical experience; 67% of Ss had seen at least one such client during that period. Psychodynamic and behavioral therapists attributed significantly more pathology to such clients than did humanistic/existential therapists. Responses suggested that some therapists were biased in their diagnostic attitudes toward clients reporting mystical experiences. 50% of Ss said they had personally had a mystical experience.

Psychologists regularly struggle with boundary issues and multiple relationships. Knowing which boundary crossings are acceptable, when a behavior becomes a boundary violation, and which multiple relationships are acceptable and which are not can present great challenges for practicing psychologists. Furthermore, for those who work with diverse populations, these challenges may become even more pronounced. A rational approach to addressing boundaries and multiple relationships is presented along with 4 expert commentaries that further elucidate these issues. Special attention is paid to the role of culture and other diversity factors as they affect how psychologists address boundaries and multiple relationships. Recommendations for ethical and effective practice that incorporate rational decision making and attention to individual differences are made.

Most child psychologists would agree that treating anxiety disorders in children is extremely challenging at times but also rewarding. This article provides an updated look at assessment strategies and promising psychosocial treatment techniques for children with 3 common anxiety disorders: separation anxiety disorder, social phobia, and generalized anxiety disorder. The need for comprehensive diagnostic evaluations is highlighted through information on the wide range of assessment procedures and instruments available to practicing psychologists interested in treating anxious youth. In addition, a treatment approach shown to be empirically efficacious for treating anxious children, cognitive-behavioral therapy, is described. We provide practical examples of assessment and treatment techniques for clinical practice. Tables are included that can serve as useful quick references for the 3 areas covered.
