Biochar immobilized plant growth-promoting rhizobacteria enhanced the physicochemical properties, agronomic characters and microbial communities during lettuce seedling.

Spent mushroom substrate (SMS) is the by-products of mushroom production, which is mainly composed of disintegrated lignocellulosic biomass, mushroom mycelia and some minerals. The huge output and the lack of effective utilization methods make SMS becoming a serious environmental problem. In order to improve the application of SMS and SMS derived biochar (SBC), composted SMS (CSMS), SBC, combined plant growth-promoting rhizobacteria (PGPR, BUABN-01 and BUAYN-122) and SBC immobilized PGPR (BCP) were applied in the lettuce seedling.

Quantitative proteomic analyses reveal that energy metabolism and protein biosynthesis reinitiation are responsible for the initiation of bolting induced by high temperature in lettuce (Lactuca sativa L.).

Background: Lettuce (Lactuca sativa L.), one of the most economically important leaf vegetables, exhibits early bolting under high-temperature conditions. Early bolting leads to loss of commodity value and edibility, leading to considerable loss and waste of resources.

Quantitative Proteomics Analysis of Lettuce ( L.) Reveals Molecular Basis-Associated Auxin and Photosynthesis with Bolting Induced by High Temperature.

Bolting is a key process in the growth and development of lettuce ( L.). A high temperature can induce early bolting, which decreases both the quality and production of lettuce.

Beneficial Phytochemicals with Anti-Tumor Potential Revealed through Metabolic Profiling of New Red Pigmented Lettuces (Lactuca sativa L.).

The present study aimed to compare polyphenols among red lettuce cultivars and identify suitable cultivars for the development and utilization of healthy vegetables. Polyphenols, mineral elements, and antioxidant activity were analyzed in the leaves of six red pigmented lettuce ( L.) cultivars; thereafter, we assessed the anti-tumor effects of cultivar B-2, which displayed the highest antioxidant activity.

Association of down-regulation of calcitonin gene-related peptide and substance P with increase of myocardial vulnerability in diabetic neuropathic rats.

Diabetic patients present high co-morbidities of neuropathy and severer consequences of coronary heart disease. But the pathological mechanism is still unclear. Here we investigated a potential association of diabetic impairment of sensory nerves with increase of vulnerability of myocardium in acute myocardial ischemia/reperfusion.

[Effects of temperature on leaf lettuce vernalization.].

To investigate the effects of different temperatures on the vernalization of leaf lettuce, and declare their type, two easy bolting leaf lettuce varieties of GB-30 and GB-31 were selected as material, which were treated by 4 ℃, 20 ℃ and 25 ℃ for 20 d respectively and afterwards treated by high temperature stress. The process of flower bud differentiation was observed by using paraffin section technology, and combined the condition of bolting and flowering to estimate whether or not it underwent vernalization, and defined its vernalization type. The results showed that, two varieties of GB-30 and GB-31 appeared bolting to different degrees at the 8 day under high temperature stress after temperature treatments in the early stage.

Preservation of CGRP in myocardium attenuates development of cardiac dysfunction in diabetic rats.

Background: Calcitonin gene-related peptide (CGRP) plays an important role in cardiovascular regulation, which was found reduced in serum of diabetic patients. To test the hypothesis that lack of CGRP in myocardium is associated with diabetic cardiac dysfunction, which may be improved by preservation of CGRP in diabetic rats.

Methods And Results: Diabetes was induced in male Sprague-Dawley rats by streptozotocin (50mg/kg).

Correlates of unequal access to preventive care in China: a multilevel analysis of national data from the 2011 China Health and Nutrition Survey.

Background: Preventive care has an essential role in reducing income-related health inequalities. Despite a general consensus of the need of shifting focus from disease treatment to wellness and prevention, little is known about inequalities in access to preventive care in China. Our study aimed to explore the inequalities in preventive care usage and factors that were associated with such inequalities among Chinese adults.

[Salt stress tolerance of cucumber-grafted rootstocks].

Taking 4 different Cucurbita maxima x C. moschata rootstocks for cucumber (Cucumis sativus) as test materials, a solution culture experiment was conducted to study their growth and antioxidative enzyme activities under the stresses of Ca(NO3)2 and NaCl, with the salt stress tolerance of the rootstocks evaluated by subordinate function. At 30 mmol x L(-1) of Ca (NO3)2 or 45 mmol x L(-1) of NaCl, the growth of the rootstock seedlings was improved; but at 60 and 120 mmol x L(-1) of Ca(NO3)2 or 90 and 180 mmol x L(-1) of NaCl, the growth and the antioxidative systems of the seedlings were inhibited, and the salt injury index of 'Qingzhen No.

[Assessing quality of life in an urban population in Chengdu using the SF-12].

Objective: To assess the health-related quality of life in an urban population in Chengdu China using the SF-12.

Methods: A random sampling strategy stratified by age and sex was adopted to select the participants in Chengdu. A total of 1365 respondents with an age of older than 18 years completed the interviewer-administered SF-12 survey.

[Culture and quality of life assessment in Chinese populations].

Objective: To investigate the impact of cultural factors on quality of life (QOL) and to identify appropriate ways of dividing sub-populations for population norm-based quality of life assessment.

Methods: The WHOQOL-BREF was used as a QOL instrument. Another questionnaire was developed to assess cultural values.

Associations between poor health and school-related behavior problems at the child and family levels: a cross-sectional study of migrant children and adolescents in southwest urban China.

Background: Due to urbanization in China, the numbers of migrant children and adolescents in urban environments have increased. Previous studies have indicated that children and adolescents are more likely to suffer from health problems and poor school achievement. The present study identified associations between poor health and school-related behavior problems (ie, learning attitudes and learning disabilities [LL], antisocial behavior and risk behavior [AR], and social adaptation and role function [SR]) at the child and family levels.

Quality of life and hostile mentality trend of patients with HIV/AIDS in China.

Objective: To assess the quality of life (QOL) and hostile mentality trend (HMT) of patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in China, and to identify their major concerns.

Study Design And Methods: Short Form-36 (SF-36) was used to assess QOL, and seven items were developed to assess the HMT. In-depth interviews were conducted with patients and health workers.

[Quantitative assessment of risks for coronary heart diseases in urban residents in Sichuan].

Objective: To set a quantitative criteria for determining risk for coronary heart disease (CHD) so that potential risk of an individual dying from CHD can be identified and to lay a foundation for predicting individual risk of CHD.

Methods: Data of case-control and cohort studies published during 1978 to 2002, as well as data of surveillance of behavior exposure in Sichuan province, were collected by retrieval of literatures. Pooled odds ratios (OR) and relative risks (RR) of all risk factors for CHD were estimated using various statistical models with software for meta-analysis, and attributable risk fractions of varied levels of risk factors could be converted.
