Fen eğitimi alanında, kimya önemli bir yer tutmaktadır. Özellikle dersi kapsamında pek çok soyut ve zor kavram içeren konuların olması, öğrenci zihninde yanılgılarının yaygın olarak oluşmasına sebep olabilmektedir. Bu bağlamda, görsel üç boyutlu öğrenme son derece büyük öneme sahiptir. amaca yönelik olarak, eğitimine hizmet etmek adına mobil uygulama geliştirilmiştir. araştırmanın amacı, Apple ...

Purpose. To evaluate the effect of polydextrose (PDX) on Ca bioavailability and prevention of loss of bone mass. Methods. Twenty-four two-month-old ovariectomized rats were fed three isocaloric diets only varied in fiber source and content up to 60 days (FOS group, a commercial mixture of short- and long-chain fructooligosaccharide, OVX group fed AIN 93 diet, and PDX group). A SHAM group was in...

I. The object was to investigate the importance of urea as a source of ammonia in the large intestine of herbivores. Urea was present in small intestinal contents of slaughtered horses in concentrations similar to those in blood but, in the small intestine of slaughtered sheep, the urea was less than in blood. 2. There was little ammonia in small intestinal contents of slaughtered horses but co...

Coccidiosis is a parasitic disease with major economic impact, one of whose main causative agents is Eimeria tenella. Chicken breeds display variable natural resistance to this disease. Unravelling the genetic bases of such variations could provide new clues for protection strategies. Transcriptomic experiments were conducted comparing resistant (Fayoumi) and susceptible (Leghorn) lines. Caecum...

Intestinal adaptation (small intestinal weight and length, weight of the caecum and of the residual colon) to feeding different doses (0-5-50-500 mg/kg bw) of the absorbable, competitive a-glucosidase inhibitors BAY m 1099 and BAY o 1248 for three, seven, or 28 days was studied in rats. With the highest dose of either inhibitor, a significant and time dependent growth of the caecum was observed...

It has been considered that hepatic caecum of amphioxus is precursor of vertebrate liver. Alpha 2 macroglobulin (A2m) ancient native immune factors are mainly synthesized in liver in vertebrate and is essential for liver formation in fish. In this study, the developmental expression patterns of A2m in amphioxus Branchiostoma japonicum were examined to seek some embryonic functionally evidence f...
