Estimation of inheritance of some agronomical characters in common wheat by diallel cross analysis [Ekmeklik bugdayda diallel melez analizi ile bazi tarimsal karakterlerin kalitiminin belirlenmesi]

This study was conducted to determine the genetic structure of a population which included six common wheat cultivars or lines and crosses of half diallel cultivars or lines. It was concluded that the epistatic effect was significant for a weight of 1000 grains and yield per plant, while the additive effect was significant for period of maturity, the number of spikelets per head, and the number of kernels per hear. The dominance effect was found in yield per plant. A partial dominance effect was found in other characters. It was found that at least 4 pairs of genes were effective on the number of spikelets per head; 2 pairs of genes were effective on yield per plant. It could not be determined how many genus played a role in other characters

Neurological symptoms at pediatric acute lymphoblastic leukemia [Çukurova bölgesindeki çocukluk akut lenfoblastik lösemili olgularda nörolojik bulgularin degerlendirilmesi]

A retrospective study was performed involving 93 patients, identified central nervous system (CNS) infiltration and/or had neurological symptoms and/or signs, of 501 patients with acute lymphoblastic leukemia (ALL) at University of Çukurova, Balcali Hospital over nine years period. The purpose of this study was to determine the frequency of neurological complications occurred during malignant diseases. In patients with ALL, headache (38.7%) was the most common symptom and altered level of consciousness (28%) was the most common signs of physical examination. 25 (26.8%) patients with ALL had a cranial nerve paralysis. Of the patients with cranial nerve paralysis, 21 had facial nerve paralysis. The period of time, between at the time of initial diagnosis and at the time occurred first neurological sign, was mean 11.84±25.62 months. The period of time, between at the time of initial diagnosis and at the time determined CNS infiltration, also, was 16.14±16.9 months. In conclusion, it is necessary that the risk factors of CNS involvement are considered for the purpose of the treatment planning of the patients with ALL for whom CNS involvement have just kept on by an important problem and so the presymptomatic CNS therapy should be put into practice far more carely. The current therapies of ALL is, anyway, planned by considering to the risk factors of CNS infiltration

The results of treatment with idarubicin in childhood acute nonlymphoblastic leukemia

PubMedID: 15074372Anthracycline and cytosine arabinoside are used in combination as the standard therapy for remission induction of acute nonlymphoblastic leukemia. Idarubicin, a synthetic daunorubicin analogue, shows an improved spectrum activity and diminishes acute or chronic toxicity when compared with the other anthracyclines. This study has been carried out in our clinic in order to evaluate the efficiency of the acute nonlymphoblastic leukemia protocol which includes idarubicin. Thirty-eight patients admitted to our Department between 1992-1999 and diagnosed as acute nonlymphoblastic leukemia (ANLL) were included in the study. Their median age was 7 years 6 months (range, 8 months to 14 years). Induction therapy consisted of idarubicin plus cytosine arabinoside and etoposide. Consolidation therapy consisted of two courses, followed by maintenance therapy with thioguanine, cytosine arabinoside, vincristine and cyclophoshamide. The complete remission rate was found to be 71%. The overall survival estimate was found to be 40% for one year and 23% for three years. We established that the protocol with idarubicin reached a higher remission ratio when compared with the other protocols with anthracycline. However, the degree of the hematologic toxicity ratios related to the therapy increased the complication ratios, which affected the long-term life analyses directly. Therefore this protocol may be revised according to socioeconomical conditions, especially in the developing countries

Preservice science teachers' belief systems about teaching a socioscientific issue

We investigated the belief system of Turkish preservice science teachers (PSTs) about teaching a socioscientific issue (GM Foods) using a belief system model. This model includes three belief pools: content beliefs (CBs), core pedagogical beliefs (CPBs) and pedagogy of content beliefs (PCBs). Based on this model, we developed a questionnaire in order to see interrelationships among three belief pools about teaching GM Foods. For content beliefs, we selected content knowledge, risk perceptions, moral beliefs and religious beliefs. For pedagogy of content beliefs, we selected teaching efficacy, preferred teaching methods and preferred teacher's roles. We administered the questionnaire to 423 PSTs. Using correlation analysis, multinomical logistic regression and structural equation modelling we tried to understand the relationships between CBs and PCBs and to make interpertations about possible CPBs working as a filter between CBs and PCBs. The results show that PSTs are relatively knowledgeable, hold high risk perceptions and certain moral and religious beliefs about GM Foods. They possess high teaching efficacy beliefs, choose the teaching role of Neutral Impartiality and prefer large class discussion and computer-assisted teaching. As core pedagogical beliefs (CPBs), they may have traditional epistemologies, moral and religiously-based teaching goals. © ISSN:1304-6020
