Twenty one dogs, distributed into four groups, were trained pre-operatively in differentiation of auditory location or frequency cues. In each group instrumental responses, reinforced by food consisted in placing by the animal its right paw on the side levers. The first differentiation, go-left, go-right task with two location cues, required the animal to(More)
Based on seedling resistance tests, five resistance genes (Lr10, Lr3, Lr13, Lr14a and Lr37) against leaf rust (Puccinia triticina) were identified in 16 cultivars of European winter wheat. STS and SCAR markers were used to verify the presence of the resistance genes Lr37 and Lr10 against leaf rust in cultivars, near-isogenic lines and segregating(More)
Genotyping of 98 wheat cultivars/lines was carried out with molecular markers that are linked to the Pm1 locus: two bi-allelic (dominant) markers: the sequence-tagged site Xsts638-7A and the amplified fragment length polymorphism XE39M58-77-7A; and the multi-allelic simple sequence repeat marker Xgwm344-7A. Employing segregation data recorded in the(More)
In 20 dogs the manipulatory go left – go right differentiation to acoustic directional cues was elaborated. All dogs received total prefrontal, or dorsolateral (total or partial) or medial (total or partial) cortical ablations. All total ablations markedly affected performance of the task, whereas the partial removals produced moderate or no impairment.(More)
The authors describe a 7-year-old boy with severe epilepsy cured by means of two-stage hemispherectomy. Epileptic seizures occurred in the left extremities and recurred several tens of times daily despite intensive pharmacological treatment. EEG investigations demonstrated seizure activity in the right motor-parietal-temporal area. Stereotaxic destruction(More)
In our clinic at the Medical Academy in Warsaw 282 patients with temporal lobe epilepsy were treated surgically. The causes of the illness were trauma in 43.2%, including birth trauma in 19.5%, infections diseases in early life in 19.8%, and microtumours in 6.8%. In 30% the aetiology was unknown. Fifty per cent had fits before 10 years and 75% before 20(More)
The authors report a statistical analysis of the levels of phenobarbital (PH) and diphenylhydantoin (DPH) in a group of 100 patients with different types of epilepsy mostly resistant to pharmacological treatment. The mean values of PH and DPH were compared with the types of epilepsy, duration of the disease, additional treatment, EEG changes and therapeutic(More)
