[Effects of daytime sub-high temperature on greenhouse tomato growth, development, yield and quality].
Zhang J, Li T, Xu J.Author information JieKey Laboratory of Protected Horticulture of Liaoning Province, Department of Horticulture, Shenyang Agricultural University, Shenyang 110161, China. zhangjie20020317@163.comAbstractThe study on the effects of daytime sub-high temperature (30 and 35 degrees C) in spring and autumn on the growth, development, yield and quality of greenhouse tomato in northeast China showed that compared with the plant growing under feasible temperature 25 degrees C, three days' daytime sub-high temperature increased the relative growth significantly, and made the plant spindling. Seven days or more sub-high temperature made the plant grow fast, with thinner leaves and presenility. Under sub-high temperature, the harvest time was earlier, the fruit weight and the 2nd and 3rd inflorescence lessened, the quality of fruit decreased, and the yield decreased significantly. Sub-high temperature had a strong influence on the normal growth and development of greenhouse tomato. The longer the plant suffered sub-high temperature from flower bud differentiation to fruit maturing, the worse the fruit quality, and the lower the yield would be.

Presenility of granulocytes in Down syndrome individuals.
Yasui K, Shinozaki K, Nakazawa T, Agematsu K, Komiyama A.Author information Department of Pediatrics, Shinshu University School of Medicine, Matsumoto, Japan. koyasui@gipac.shinshu-u.ac.jpAbstractNeutrophil function defects occur in individuals with Down syndrome (DS). We examined apoptosis of granulocytes (neutrophils and eosinophils) in DS individuals and control healthy subjects. Granulocyte survival was shortened in DS individuals, and the percentage of apoptotic granulocytes from DS during incubation was significantly higher than that from healthy subjects. The difference was time-dependent, and that between DS and healthy subjects was nearly 30% after longer periods of incubation. In control granulocytes, both granulocyte-macrophage colony-stimulating factor (10 ng/ml) and interleukin-5 (5 ng/ml) counteracted the programmed cell death and delayed the apoptosis caused by anti-Fas antibodies, whereas those inflammatory cytokines were not able to completely prevent cellular apoptosis in DS patients. Apoptosis and functional impairment of granulocytes may contribute to the risk of infections underlying pathological conditions of DS, and accelerated apoptosis of granulocytes may be a factor to prevent chronic airway inflammation and bronchial asthma in DS individuals.

Improvement of the DNA repair capacity of human fibroblasts by autolysates of Lactobacillus gasseri.
Weirich-Schwaiger H, Weirich HG, Kludas M, Hirsch-Kauffmann M.Author information Institut für Medizinische Biologie und Genetik der Universität Innsbruck, Austria.AbstractAutolysates of Lactobacillus gasseri were tested for their ability to improve repair capacity in cultured human fibroblasts. In the course of this research on molecular mechanisms of hereditary DNA repair deficiencies and presenility syndromes, a significant and reproducible effect on repair capacity in these cells by an autolysate of the gram-positive bacterium Lactobacillus gasseri was found.
