Acrylamide (ACR) is neurotoxic to experimental animals and humans. The literature on its neurotoxic effect in the mature animals is huge, but the effect of acrylamide on the immature is relatively less understood. The present study was carried out to investigate the hematological, biochemical, neurological and histopathological effects of acrylamide (15 mg/kg b.wt.) in immature and mature male and female rats as well as mature male and female rats at (50 mg/kg b. wt.). As could be shown histopathological alteration in the structures of treated liver, kidney, brain, testis and ovary which resulted following ACR administration. In conclusion, the present study showed that, acrylamide induced hematological, biochemical, neurological and histopathological disorders in the immature and mature male and female rats. So, we recommended that it must be eat a balanced diet, rich in fruits and vegetables and avoid fast or junk foods. Key

A crop breeding programs amid to increasing plant productivity requires consideration not only for yield but also of its components which have direct or indirect contribution on yield. Several methods of selection can be used in segregating generation after crossing in self pollinated crops. The information for each of the method of selection as well as the relationship between these methods of selection and yield would help in determining the best method of selection for breeding program to follow for high yielding varieties of wheat and applied this method in the following breeding program.

Chlamydia pneumoniae is a major cause of acute respiratory tract diseases in human and has been responsible for both endemic and epidemic pneumonia. In addition, this organism is thought to play some roles in other clinical manifestations, like coronary artery diseases, asthma and sarcoidosis. This is the first Saudi Arabian study that investigates the prevalence of this organism in Saudi Arabia, its pathogenesis and immunological response. The study employed a wide range of advanced techniques and methods, including culturing, detection by immunoflourescence, polymerase chain reaction (PCR), electron microscopy, antichlamydial activity assays and the most recent advanced technique of microarray technology.
