Routine treatment of burns with cultured skin substitutes (CSS) has been limited by poor engraftment and by scarring. Hypothetically, topical application of essential nutrients and/or growth factors may support epithelial survival temporarily during graft vascularization. CSS, composed of human epidermal keratinocytes and dermal fibroblasts attached to collagen-glycosaminoglycan substrates, wer...

Effective management of limited water resources in the North China Plain requires reliable calculation of historical groundwater balances at local, sub-watershed scales. These calculations typically are hindered by poorly constrained recharge estimates. Using a simple soil-water balance model, we independently calculated annual recharge from irrigated cropland to unconfined alluvial aquifers un...

On marginal lands in the Mediterranean basin, giant reed (Arundo donax L.) represents one of most interesting perennial crops due to high levels biomass production. Considering periodic water shortage during summer months this area, reuse treated wastewater (TWW) would seem be a good opportunity for growth species. The aim study was assess medium-term effects irrigation using freshwater (FW) an...

Malaria vector Anopheles and other mosquitoes (Diptera: Culicidae) were monitored for 12 months during 1994-95 in villages of Lower Moshi irrigation area (37 degrees 20' E, 3 degrees 21' S; approximately 700 m a.s.l.) south of Mount Kilimanjaro in northern Tanzania. Adult mosquito populations were sampled fortnightly by five methods: human bait collection indoors (18.00-06.00 hours) and outdoor...

Success in endodontics depends largely on the activity of the irrigation solutions used during canal cleaning and shaping. Sometimes the irrigation solutions should act deep within the dentin, particularly in cases of chronic infectious lesions, in which it has been found that germs can lodge in the depths of the dentinal tubules. The aim of this study was to compare the penetration of methylen...
