Extensive expts. over a number of years revealed that pp. DDT (0.1-0.2%) and gamma BHC (50-100 ppm.) without As were ineffective against ticks (except blue tick Boophilus decoloratus) and that such solns. deteriorate rapidly, especially solns. of...

Baumgart, D.C.; Wiedenmann, B.; Dignass, A.U., 2003: Biologische Therapie chronisch-entzuendlicher Darmerkrankungen. Biological therapies in inflammatory bowel disease reflect the exponential advancement in understanding the human intestinal immune system and particularly the biology of intestinal inflammation during the past decade. The better understanding of...

Jin, R.; Huang, X.; Li, H.; Yuan, Y.; Li, B.; Cheng, C.; Li, Q., 2014: Laser therapy for prevention and treatment of pathologic excessive scars. The management of hypertrophic scars and keloids remains a therapeutic challenge. Treatment regimens are currently based on clinical experience rather than substantiated evidence. Laser therapy is an emerging minimally invasive treatment that has...

Sugimoto, M.; Yasuda, T., 1983: Asymmetric (differential) cell division of thymic lymphocytes by means of cytoplasmic polarization: possible biological meanings. A series of morphological studies at the light- and electron-microscopical levels have led to the conclusion that a significant proportion of immature thymic lymphocytes would undergo asymmetric (differential) cell division: at the telophase of su...

Benchimol-Barbosa, P.Roberto., 2008: Comments on the article by Chen-Scarabelli and Scarabelli: history of medicine in the 'hidden world' and relevant articles in systematic reviews. When writing a review manuscript, choosing among potentially citable references is an arduous task. Decisions are commonly based on several aspects, ranging from obvious content relevance, passing through impact factor of the journal in which a pr...

Hölker, U.; Dohse, J.; Höfer, M., 2002: Extracellular laccases in ascomycetes Trichoderma atroviride and Trichoderma harzianum. Laccase activity in T. harzianum and in our own isolate of T. atroviride was correlated with the production of the green pigment in conidial spores. The laccases of the two fungal species showed comparable kinetic parameters, pH optima, and therma...

Patil, J.D., 2002: Crop life saving measures in dryland agriculture. This chapter focuses on the various practices to increase or stabilize the yield of dryland crops: (1) early sowing of rabi crops; (2) dust mulching and/or mulching of organic materials; (3) timely control of weeds; (4) adjustment in crop density;...

Causton, A.S.; Sherman, J.C., 1999: Design of proteins using rigid organic macrocycles as scaffolds. We have designed and synthesized new three-helix template-assembled synthetic proteins (TASPs) 1a-c. The template was the rigid cyclotribenzylene (CTB) macrocycle 2, which has C3 symmetry. Thiol moieties on the CTB template were used to link cyste...
