Prediction of Multimorbidity in Brazil: Latest Fifth of a Century Population Study.

Background: Multimorbidity is characterized by the co-occurrence of 2 or more chronic diseases and has been a focus of the health care sector and health policy makers due to its severe adverse effects.

Objective: This paper aims to use the latest 2 decades of national health data in Brazil to analyze the effects of demographic factors and predict the impact of various risk factors on multimorbidity.

Methods: Data analysis methods include descriptive analysis, logistic regression, and nomogram prediction.

How fall dormancy benefits alfalfa winter-survival? Physiologic and transcriptomic analyses of dormancy process.

Background: Fall dormancy and freezing tolerance characterized as two important phenotypic traits, have great effects on productivity and persistence of alfalfa (Medicago sativa L.). Despite the fact that one of the most limiting traits for alfalfa freezing tolerance in winter is fall dormancy, the interplay between fall dormancy and cold acclimation processes of alfalfa remains largely unknown.

Pollution characteristics of metal pollutants in PM and comparison of risk on human health in heating and non-heating seasons in Baoding, China.

PM particles were collected to study the distribution, accumulation and health risk assessment of metal pollutants. The concentrations of 11 kinds of metal elements in PM during heating period and non-heating period were analyzed. Based on the American health risk assessment model as well as the human exposure parameters in China, the human health risk was assessed.

[Effects of pomegranate varieties on the development and fecundity of Assara inouei Yamanaka (Lepidoptera: Pyralidae)].

Assara inouei Yanmanaka is an important pest of pomegranate fruits in Yunnan Province. To examine the effects of different pomegranate varieties on the development and reproduction of A. inouei, the biological characteristics, such as the developmental duration, the survival rate and reproduction of this pest feeding on five pomegranate varieties including Tianlvzi, Houpitianshazi, Tianguangyan, Suanlvzi and Suanshazi were observed respectively, and the life table parameters were established under the laboratory conditions of (25±1) ℃, RH (70±10)% and a photoperiod of 15 L:9 D.

[Effects of mowing and grazing on soil nutrients and soil microbes in rhizosphere and bulk soil of Stipa grandis in a typical steppe].

This study conducted experiments using Stipa grandis, the dominant species of the typical steppe in Inner Mongolia. The research explored the different effects of mowing and grazing on organic carbon, total nitrogen, available nitrogen, total phosphorus and available phosphorus in rhizosphere and bulk soil. The results showed that: Both mowing and grazing inhibited assemble and storage capacity of rhizosphere, and decreased the organic carbon, total nitrogen, and available nitrogen contents in rhizosphere soil.

[Effect of acupuncture on heroin cue-induced functional magnetic resonance images in heroin-addicted human subjects].

Objective: To observe heroin cue-induced changes of cerebral functional magnetic resonance images (fMRI) and the effect of acupuncture of Zusanli (ST 36) on them under craving state in heroin-addicted volunteers.

Methods: Fourteen male volunteer heroin addicts were recruited in the present study. Brain images were acquired before, during (2 min) and after visualizing heroin (placed in a transparent glass mug) and acupuncture of Zusanli (ST 36) on a 1.
