background and purpose: the fact that who is more qualified to teach the emp (english for medical purposes) courses has long been the cause of argument between the heads of language departments (lds) on one side and those of discipline-specific departments(dsds) on the other side. this research was conducted to study the views of both sides as well as those of students in some emp english class...

Wireless sensor network used Clustering techniques to extend the lifetime of the network. LEACH is the one from these clustering techniques to maintain the energy efficiency of sensors. The technique of selecting nodes with highest residual energy as cluster heads with the assumption that energy consumption distribute periodically between the nodes. Cluster heads collect information from the su...

There is currently concern and controversy in the shrimp industries of the Americas about the risk posed by the importation and reprocessing of shrimp infected with white spot syndrome virus (WSSV) and yellow head virus (YHV). To further understand the risk, more knowledge concerning the quantitative virus load of infected shrimp is needed. The present study was carried out to better define, us...

The aim of this study is to reveal the morphology of the lyssa in the cat and dog. Eight heads of adult healthy cats and eight heads of dogs of both sexes were used as materials. In the cat the lyssa, yellow coloured, had a helical appearance and its edge facing the oral cavity became sharp; in the dog the lyssa, pinkish white coloured, was more or less J-shaped. The whole body of the cat’s lys...

Glutathione S-transferase (GST) activity pattern was determined in tolerant (cv. Sumai#3) and susceptible (cv. Falat) wheat heads inoculated with Fusarium graminearum, the causal agent of head scab disease (FHB), during various developmental stages. GST specific activity exhibited a transient pattern in Sumai#3 reaching a maximum level at the milk stage and declining thereafter. GST level in Su...

OBJECTIVE To determine the distribution of lesions and extent of tissues infected with Mycobacterium bovis in a captive population of white-tailed deer. DESIGN Cross-sectional study. ANIMALS 116 captive white-tailed deer. PROCEDURE Deer were euthanatized, and postmortem examinations were performed. Tissues with gross lesions suggestive of tuberculosis were collected for microscopic analys...

BACKGROUND To observe micro lesions on the cartilage of the rabbit femoral head using phase-contrast imaging with synchrotron hard X-ray and to prove that this method can be useful in the study of the degeneration of cartilage. METHODS New Zealand white rabbits were used in a micro lesion model of rabbit femoral head cartilage. Bilateral femoral heads were excised from rabbits, and micro lesi...

There are some indications that seizure activity promotes the development of stroke-like episodes, or vice versa, in patients with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome or other syndromic mitochondrial disorders. A 41-year-old Caucasian female with MELAS syndrome, presenting with short stature, microcytic anaemia, increased blood-sedimentation r...

This study was undertaken to elucidate detailed event of early embryogenesis in chicken embryos using a noninvasive egg retrieval technique before oviposition. White Leghorn intrauterine eggs were retrieved from 95 cyclic hens aged up to 54-56 weeks and morphogenetic observation was made under both bright field and fluorescent image in a time course manner. Differing from mammals, asymmetric cl...
