By the end of 2001, an estimated 40 million people worldwide—2.7 million under age 15—were living with HIV/AIDS. More than 70 percent of these people (28.1 million) live in Sub-Saharan Africa. Another killer, malaria, is responsible for as many as half the deaths of African children under the age of five. The disease kills more than one million children each year—2,800 per day—in Africa alone. ...

Su ürünleri yetiştiriciliğinde 2-fenoksietanol, MS-222 ve benzokain gibi sentetik anestetikler yaygın olarak kullanılmaktadır. Amerika İngiltere'de yemeklik balıklarda kullanılmasına yasal izin verilen tek anestetik madde MS-222’dir. İlaç Gıda Örgütü (FDA) tarafından MS-222’nin balık vücudundan atılma süresi su sıcaklığına göre farklılık göstermekle birlikte ortalama 21 gün belirtilmiştir. Bu d...

The phytohormone ethylene is essential for senescence in many fruits and flowers. In the biosynthesis of ethylene in plants, the conversion of S-adenosyl methionine (SAM) to 1-aminocyclopropane1-carboxylic acid (ACC) and the conversion of ACC to ethylene are catalyzed by ACC synthase (ACS) and ACC oxidase (ACO), respectively (Adams and Yang, 1979). Using a cDNA clone representing carnation ACO ...

The main goal of this paper is to construct three sets of road safety performance indicators, which are regional road safety performance indicators, urban road safety performance indicators and highway safety performance indicators, respectively. Fuzzy Delphi Method and Grey Delphi Method are applied to quantify experts’ attitudes to regional road safety, urban road safety and highway safety. C...

The present study aimed at evaluating the in vitro antimicrobial activity of methanolic extracts of some medicinal plants against Escherichia coli, Salmonella Typhimurium, Staphylococcus aureus and Enterococcus sp. The methanolic extract of Caryophyllus aromaticus presented the highest anti-S. aureus activity and was effective against all bacterial strains tested.

Doubled haploids of carnation (Dianthus caryophyllus L.) were obtained by pseudofertilized ovule culture. Emasculated ̄ower buds of carnation were pollinated with pollen inactivated by Xray irradiation. After 2±3 weeks, the ovaries were explanted and were cultured on solid MS medium containing 2 mM NAA, 2 mM BAP and 6% sucrose. Regenerated plants(R0) were morphologically different from the moth...
