[Ab] Abstract:OBJECTIVES: Findings regarding the benefits of fruit and vegetables (FV) on weight control are inconsistent and little is known among Chinese populations. Therefore, we examined the relationship between change in FV consumption, weight, and change in body mass index (BMI) among Chinese adults, participants of the China Health and Nutrition Survey (CHNS). STUDY DESIGN: A prospective cohort study. METHODS: Two waves of CHNS conducted in 2006 and 2011 were used. Continuous FV consumption increase was considered as the exposure and changes in weight and BMI as outcomes. Change in FV consumption was categorized into quintiles. Analysis of covariance and multiple linear regression models, after controlling for potential confounders such as energy intake, physical activity, and smoking, were used to describe the relationship between change in FV consumption and change in weight and BMI. RESULTS: A total of 4357 participants aged 18-65 years were included in this study. The respective weight and BMI gains in male individuals were 1.81 kg and 0.73 kg/m in the fifth quintile of FV change relative to individuals in the first quintile (3.67 kg for weight gain and 1.48 kg/m for BMI gain). An increase in FV consumption by 100 g was associated with a 211 g weight loss (B = -2.11; 95% confidence interval [CI], -3.34, -0.89, P < 0.001) and a decrease in BMI by 0.94 kg/m (B = -0.94; 95% CI, -1.36, -0.46, P < 0.001) in men; and a 140 g weight loss (B = -0.14; 95% CI, -0.97, 0.69, P = 0.74) and a decrease in BMI by 0.29 kg/m BMI (B = -0.29; 95% CI, -0.63, 0.06, P = 0.11) in women. CONCLUSIONS: Increase in FV consumption was associated with statistically significant weight loss and decrease in BMI among Chinese men, and, although suggested, weight loss among women was not significant. Considering the protective effect of FV on human health, increasing FV consumption in the Chinese population is recommended.

[Ti] Title:Resveratrol promotes the arcuate nucleus architecture remodeling to produce more anorexigenic neurons in high-fat-diet-fed mice.

[Ab] Abstract:OBJECTIVE: Adult hypothalamic neurogenesis has been considered a central regulator of energy balance. Resveratrol (RSV), a natural polyphenol, influences the body fat mass and reduces the amount of adipose tissue. The present study was designed to evaluate the effect of RSV on dynamic of hypothalamic neurons in a diet-induced obesity model of mice. METHODS: Apoptosis, neurogenesis, the expression of the main trophic factors, and the fate of newborn cells were evaluated in the hypothalamus of adult male C57 BL/6 J mice fed a normal diet, a high-fat (HF) diet, or an HF diet supplemented with 400 mg/kg RSV (HF + RSV) for 6 wk. RESULTS: The HF diet caused an increase in neuronal apoptosis in the hypothalamus, which coincided with an increase in the number of newborn cells in the arcuate nucleus, suggesting that compensatory mechanisms developed to overcome deleterious effects of the HF diet. Addition of RSV to the HF diet enhanced the production of newborn cells in all studied regions of the hypothalamus. These changes were paralleled by enhancement of the expression of ciliary neurotrophic factor. Interestingly, a considerable proportion of newborn cells expressed neuropeptide Y in the arcuate nucleus of the HF group, and conversely, most of them differentiated to proopiomelanocortin neurons in HF + RSV mice. CONCLUSIONS: Diets rich in fat changed hypothalamic neuronal balance toward orexigenic versus anorexigenic neurons. Administration of RSV to the HF diet reversed this balance toward generation of anorexigenic neurons. These data point to the potential for RSV in regulation of body weight, possibly via modulation of hypothalamic neurogenesis.

[Ti] Title:Calpeptin is neuroprotective against acrylamide-induced neuropathy in rats.

[Ab] Abstract:The aim of this study is to explore the potent neuroprotective effect of calpeptin (CP) on neuron damage induced by acrylamide (ACR) and its mechanism. Behavioural indicators such as hind limb splay, rota-rod performance, and gait analysis were assessed weekly to evaluate neurobehavioural changes after ACR and/or CP administration. The histopathological alterations and the changes of µ-calpain, m-calpain, microtubule-associated protein 2 (MAP2), and α-tubulin and ß-tubulin protein levels in spinal cord were determined. Results showed that after administration of 30 mg/kg ACR, decreased body weight, attenuated neurobehavioural function, injury of motor neuron, increased protein levels of m-calpain and ß-tubulin, suppressed MAP2 protein level, and no significant changes of µ-calpain and α-tubulin protein levels were observed compared with the control group rats. After administration of 200 µg/kg CP, partially restored body weight and neurobehavioural function, improvement of motor neuron injury, decreased protein levels of m- calpain and ß-tubulin, and reversed effects of MAP2 protein level were observed compared with the ACR group rats. Our results suggested that CP alleviates neuropathy induced by ACR in rats. The calpain's overactivation causes the degrading of MAP2 and eventually leads to the destruction of microtubules (MTs), which may be one of the mechanisms of cytoskeletal damage induced by ACR.

[Ab] Abstract:BACKGROUND: Airway type 2 inflammation is usually corticosteroid sensitive, but the role of type 2 inflammation as a mechanism of asthma in patients on high dose inhaled corticosteroids (ICS) is uncertain. OBJECTIVE: To determine if airway type 2 inflammation persists in patients treated with ICS and to evaluate the clinical features of patients with steroid resistant airway type-2 inflammation. METHODS: We used qPCR to generate a composite metric of type-2 cytokine gene expression (type 2 Gene Mean, "T2GM") in induced sputum cells from healthy controls, severe asthma patients on ICS (n=174), and non-severe asthma patients on ICS (n=85). We explored relationships between asthma outcomes and the T2GM, and the utility of non-invasive biomarkers of the airway T2GM. RESULTS: The sputum cell T2GM in asthma subjects was significantly increased in asthma subjects and remained high following treatment with intramuscular triamcinolone. We used the median value for the T2GM as a cutoff to classify "steroid-treated type 2-low" (stT2-low) and "steroid-resistant type 2-high" (srT2-high) subgroups. Compared to patients with stT2-low asthma, those with srT2-high asthma were older age and had more severe asthma. Blood eosinophil cell counts predicted srT2-high asthma when BMI was < 40, but not when it was ≥40, whereas, blood IgE strongly predicted srT2-high asthma when age was < 34 years but not when it was ≥34. CONCLUSION: Despite ICS therapy many asthmatics have persistent airway type 2 inflammation, (srT2-high asthma) and these patients are older and have more severe disease. Body weight and age modify the performance of blood-based biomarkers of airway type-2 inflammation.

[Ti] Title:MiR-223/Pknox1 axis protects mice from CVB3-induced viral myocarditis by modulating macrophage polarization.

[Ab] Abstract:Macrophage polarization plays a crucial role in regulating myocardial inflammation and injuries of coxsackievirus B3 (CVB3)-induced viral myocarditis (VM). It has been reported that miR-223 is a potent regulator of inflammatory responses that involved in macrophage polarization. However, the functional roles of miR-223 in CVB3-induced VM still remain unknown. Here, we found that miR-223 expression was significantly down-regulated in heart tissues and heart-infiltrating macrophages of CVB3-infected mice. Up-regulation of miR-223 in vivo protected the mice against CVB3-induced myocardial injuries characterized by the increased body weight and survival, enhanced left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS), relieved inflammation, depressed creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH) and aspartate transaminase (AST) levels, reduced production of interferon (IFN)-γ, interleukin (IL)-6 as well as increased IL-10. We subsequently found that miR-233 up-regulation significantly suppressed the expression of M1 markers (iNOS, TNF-α and CD 86), and promoted the expression of M2 markers (Arginase-1, Fizz-1 and CD 206) in vivo and in vitro. Furthermore, we confirmed that miR-223 directly targeted Pknox1 to inhibit its expression, and the expression of Pknox1 was inversely correlated with miR-223 expression in heart tissues and heart-infiltrating macrophages of CVB3-infected mice. Gain-of-function analyses indicated that Pknox1 overexpression partially reversed the polarization phenotypes regulated by miR-223 overexpression. Taken together, the data suggest that miR-223 protects against CVB3-induced inflammation and myocardial damage, which may partly attribute to the regulation of macrophage polarization via targeting Pknox1.

[Ab] Abstract:Objective: To evaluate the effect of patient characteristics on popliteal aortic contrast enhancement at lower extremity CT angiography (LE-CTA) scanning. Materials and Methods: Prior informed consent to participate was obtained from all 158 patients. All were examined using a routine protocol; the scanning parameters were tube voltage 100 kVp, tube current 100 mA to 770 mA (noise index 12), 0.5-second rotation, 1.25-mm detector row width, 0.516 beam pitch, and 41.2-mm table movement, and the contrast material was 85.0 mL. Cardiac output (CO) was measured with a portable electrical velocimeter within 5 minutes of starting the CT scan. To evaluate the effects of age, sex, body size, CO, and scan delay on the CT number of popliteal artery, the researchers used multivariate regression analysis. Results: A significant positive correlation was seen between the CT number of the popliteal artery and the patient age ( = 0.39, < 0.01). A significant inverse correlation was observed between the CT number of the popliteal artery and the height ( = -0.48), total body weight ( = -0.52), body mass index ( = -0.33), body surface area (BSA) ( = -0.56), lean body weight ( = -0.56), and CO ( = -0.35) ( < 0.001 for all). There was no significant correlation between the enhancement and the scan delay ( = 0.06, = 0.47). The BSA, CO, and age had significant effects on the CT number (standardized regression: BSA -0.42, CO -0.22, age 0.15; < 0.05, respectively). Conclusion: The BSA, CO, and age are significantly correlated with the CT number of the popliteal artery on LE-CTA.

[Ab] Abstract:The normal physiological loads from muscles experienced by the spine are largely unknown due to a lack of data. The aim of this study is to investigate the effects of varying muscle directions on the outcomes predicted from finite element models of human lumbar spine. A nonlinear finite element model of L3-L5 was employed. The force of the erector spinae muscle, the force of the rectus abdominis muscle, follower loads, and upper body weight were applied. The model was fixed in a neural standing position and the direction of the force of the erector spinae muscle and rectus abdominis muscle was varied in three directions. The intradiscal pressure, reaction moments, and intervertebral rotations were calculated. The intradiscal pressure of L4-L5 was 0.56-0.57 MPa, which agrees with the pressure of 0.5 MPa from the literatures. The models with the erector spinae muscle loaded in anterior-oblique direction showed the smallest reaction moments (less than 0.6 Nm) and intervertebral rotations of L3-L4 and L4-L5 (less than 0.2 degrees). In comparison with loading in the vertical direction and posterior-oblique direction, the erector spinae muscle loaded in the anterior-oblique direction required lower external force or moment to keep the lumbar spine in the neutral position.

[Ab] Abstract:Available data indicate that dietary sodium (as salt) relates directly to blood pressure (BP). Most of these findings are from studies lacking dietary data; hence, it is unclear whether this sodium-BP relationship is modulated by other dietary factors. With control for multiple nondietary factors, but not body mass index, there were direct relations to BP of 24-hour urinary sodium excretion and the urinary sodium/potassium ratio among 4680 men and women 40 to 59 years of age (17 population samples in China, Japan, United Kingdom, and United States) in the INTERMAP (International Study on Macro/Micronutrients and Blood Pressure), and among its 2195 American participants, for example, 2 SD higher 24-hour urinary sodium excretion (118.7 mmol) associated with systolic BP 3.7 mm Hg higher. These sodium-BP relations persisted with control for 13 macronutrients, 12 vitamins, 7 minerals, and 18 amino acids, for both sex, older and younger, blacks, Hispanics, whites, and socioeconomic strata. With control for body mass index, sodium-BP-but not sodium/potassium-BP-relations were attenuated. Normal weight and obese participants manifested significant positive relations to BP of urinary sodium; relations were weaker for overweight people. At lower but not higher levels of 24-hour sodium excretion, potassium intake blunted the sodium-BP relation. The adverse association of dietary sodium with BP is minimally attenuated by other dietary constituents; these findings underscore the importance of reducing salt intake for the prevention and control of prehypertension and hypertension.

[Ab] Abstract:Malaria is a harmful disease affecting both tropical and subtropical countries and causing sometimes fatal complications. The effects of malaria-related complications on the intestine have been relatively neglected, and the reasons for the intestinal damage caused by malaria infection are not yet clear. The present study aims to evaluate the influence of intestinal vitamin D receptor on host-pathogen interactions during malaria induced in mice by Plasmodium chabaudi. To induce the infection, animals were infected with 10 P. chabaudi-parasitized erythrocytes. Mice were sacrificed on day 8 post-infection. The infected mice experienced a significant body weight loss and parasitaemia affecting about 46% of RBCs. Infection caused marked pathological changes in the intestinal tissue indicated by shortening of the intestine and villi. Moreover, the phagocytic activity of macrophages increased significantly (P < 0.01) in the infected villi compared to the non-infected ones. Infection by the parasite also induced marked upregulation of nuclear factor-kappa B, inducible nitric oxide synthase, Vitamin D Receptor, interleukin-1ß, tumour necrosis factor alpha and interferon gamma-mRNA. It can be implied from this that vitamin D receptor has a role in regulating malarial infection.

[Ab] Abstract:People with obesity often struggle to maintain their weight loss after a weight loss period. Furthermore, the effect of weight loss on appetite and food preferences remains unclear. Hence this study investigated the effect of weight loss on subjective appetite and food preferences in healthy, overweight and obese volunteers. A subgroup of adult participants (n = 123) from the Diet Obesity and Genes (DiOGenes) study (subgroup A) was recruited from across six European countries. Participants lost ≥8% of initial body weight during an 8-week low calorie diet (LCD). Subjective appetite and food preferences were measured before and after the LCD, in response to a standardized meal test, using visual analogue rating scales (VAS) and the Leeds Food Choice Questionnaire (FCQ). After the LCD, participants reported increased fullness (p < 0.05), decreased desire to eat (p < 0.05) and decreased prospective consumption (p < 0.05) after consuming the test meal. An interaction effect (visit x time) was found for hunger ratings (p < 0.05). Area under the curve (AUC) for hunger, desire to eat and prospective consumption was decreased by 18.1%, 20.2% and 21.1% respectively whereas AUC for fullness increased by 13.9%. Preference for low-energy products measured by the Food Preference Checklist (FPC) decreased by 1.9% before the test meal and by 13.5% after the test meal (p < 0.05). High-carbohydrate and high-fat preference decreased by 11.4% and 16.2% before the test meal and by 17.4% and 22.7% after the meal (p < 0.05). No other effects were observed. These results suggest that LCD induced weight loss decreases the appetite perceptions of overweight volunteers whilst decreasing their preference for high-fat-, high-carbohydrate-, and low-energy products.
