Differential cadmium translocation and accumulation between Nicotiana tabacum L. and Nicotiana rustica L. by transcriptome combined with chemical form analyses.

Cadmium (Cd) is a severely toxic and carcinogenic heavy metal. Cigarette smoking is one of the major source of Cd exposure in humans. Nicotiana tabacum is primarily a leaf Cd accumulator, while Nicotiana rustica is a root Cd accumulator among Nicotiana species.

Chloride salinity in a chloride-sensitive plant: Focusing on photosynthesis, hormone synthesis and transduction in tobacco.

Chloride (Cl) is a micronutrient and a beneficial ion for plant growth, but excess Cl easily leads to Cl salinity. As a species sensitive to Cl, tobacco experiences serious damage when encountering excessive Cl. However, the molecular mechanism by which excess Cl delays plant growth and development remain largely unknown.

Combination of β-Aminobutyric Acid and Ca Alleviates Chilling Stress in Tobacco ( L.).

Chilling is a major abiotic factor limiting the growth, development, and productivity of plants. β-aminobutyric acid (BABA), a new environmentally friendly agent, is widely used to induce plant resistance to biotic and abiotic stress. Calcium, as a signaling substance, participates in various physiological activities in cells and plays a positive role in plant defense against cold conditions.

Serum cholinesterase: a potential assistant biomarker for hand, foot, and mouth disease caused by enterovirus 71 infection.

Background: Hand, foot, and mouth disease (HFMD) caused by enterovirus 71 (EV71) is a potentially life-threatening infectious disease that commonly occurs in children. Diagnosis of HFMD caused by EV71 largely depends on clinical manifestations and rare serological biomarkers used to identify children suffering from HFMD. Serum cholinesterase (SChE) activity has frequently been reported as a potential biomarker for solid central nervous system tumors, chronic heart failure, and liver cirrhosis.

[Spatial and temporal characteristics of flue-cured tobacco water requirement and irrigation requirement index in Yunnan Province, China].

Based on the daily meteorological data of 124 agricultural meteorological sites during 1977-2010 in Yunnan Province, using recommended Penman-Monteith formula by FAO, water requirement and irrigation requirement index in the growth period of flue-cured tobacco were calculated to analyze their spatial and temporal characteristics and change patterns. The results showed that water requirements of flue-cured tobacco in root extending, vigorous, mature periods and field growth period during 1977-2010 were 76.73-174.

P53 Arg72Pro polymorphism and bladder cancer risk--meta-analysis evidence for a link in Asians but not Caucasians.

Objective: Individual studies of the associations between P53 codon 72 polymorphism (rs1042522) and bladder cancer susceptibility have shown inconclusive results. To derive a more precise estimation of the relationship, we performed this systemic review and meta-analysis based on 15 publications.

Methods: We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association.

[Differential expression of ubiquitin C-terminal hydrolase L-1 in the rat testis following exposure to di-n-butyl phthalate in utero].

Objective: To identify and analyze the differential expression of ubiquitin C-terminal hydrolase L-1 (UCHL1) in the testis of rat offspring after maternal exposure to di-n-butyl phthalate (DBP).

Methods: Forty pregnant rats were randomly divided into two groups and given DBP by gastric intubation at the dose of 800 mg/(kg x d) or none from the 14-18th day of pregnancy. Testes were harvested from the fetal and neonatal rats of the normal and exposed groups respectively at GD19 and PND22.

[Distribution characters of sulfur in flue-cured tobacco leaf and available sulfur in soil in hunan tobacco-growing areas].

Through field survey and laboratory analysis, this paper studied the distribution characters and interrelationships of sulfur in flue-cured tobacco leaf and available sulfur in soil in Hunan tobacco-growing areas of China. The results indicated that in Hunan tobacco-growing areas, the sulfur content in flue-cured tobacco leaf was relatively high as compared with other tobacco-growing areas in China, which ranged from 0.34% to 1.

[Study on integrative point of traditional and western medicine--from "integrative disease and syndrome" to "integrative pathological process and syndrome"].

The clinical thinking modes of "integrative disease and Syndrome" and "integrative macroscopical Syndrome-differentiation and microscopical Syndrome-differentiation" formed in the past half century were merely the primary train of thought and methodology of integrative traditional Chinese and Western medicine. In order to develop them to a higher level, stress should be put on the unity and holism of disordered organism and unity of function, structure and metabolism. It has long been ignored that a parallel and correlated relationship exists between the TCM Syndrome and pathological process of Western medicine, which is a common, set-formed and regular pathophysiological changes with certain development phase, presented in various diseases.
