Uticaj količine i oblika azota na produktivnost ozime pšenice

This paper examined the influence of the quantity and form of nitrogen on the important parameters of productivity of winter wheat. Field microexperiments were conducted in agroecological conditions of Central Serbia and loam soil type (vertisol). The results showed significant differences in the spike length, number of spikelets, grain yield and hectoliter weight between examined quantities of nitrogen. On the contrary, a form of nitrogen had not a significant effect on the observed parameters of productivity of wheat.U ovom radu je ispitivan uticaj količine i oblika azota na važnije parametre produktivnosti ozime pšenice. Poljski mikroogled je postavljen u agroekološkim uslovima centralne Srbije i na zemljištu tipa smonica (vertisol). Dobijeni rezultati su pokazali značajne razlike u dužini klasa, broju klasića, prinosu zrna i hektolitarskoj masi između ispitivanih količina azota. Suprotno tome, oblik azota nije ispoljio značajan uticaj na posmatrane parametre produktivnosti pšenice

METABOLIC ISSUES IN PSYCHOTIC DISORDERS WITH THE FOCUS ON FIRST-EPISODE PATIENTS: A REVIEW

Before the onset of the illness, future schizophrenia patients do not weigh more comparing to their peers. However, during the later course of the illness, obesity is twice as prevalent as in general public, afflicting the half of schizophrenia patient population. There is a list of potential factors that contribute to this, including lifestyle, dietary habits, unsatisfactory monitoring of physical health etc, but nowadays side effects of antipsychotic medication become the most prominent concern when weight gain and metabolic issues in psychosis are addressed. The fact is that second generation antipsychotics (SGA) are associated with weight gain and metabolic syndrome, but that might be the case with the first generation antipsychotics (FGA) too. Besides, obesity might be evident in patients before any exposure to medications, and all that bring lot of dilemmas into the field. This paper critically reviews available data on metabolic problems in patients with psychotic disorders, raging from genetic to molecular and environmental factors, and highlights the necessity of screening for the early signs of metabolic disturbances, as well as of multidisciplinary assessment of psychiatric and medical conditions from the first psychotic episode

Soluble ST2 levels and left ventricular structure and function in patients with metabolic syndrome

Background: A biomarker that is of great interest in relation to adverse cardiovascular events is soluble ST2 (sST2), a member of the interleukin family. Considering that metabolic syndrome (MetS) is accompanied by a proinflammatory state, we aimed to assess the relationship between sST2 and left ventricular (LV) structure and function in patients with MetS. Methods: A multicentric, cross-sectional study was conducted on180 MetS subjects with normal LV ejection fraction as determined by echocardiography. LV hypertrophy (LVH) was defined as an LV mass index greater than the gender-specific upper limit of normal as determined by echocardiography. LV diastolic dysfunction (DD) was assessed by pulse-wave and tissue Doppler imaging. sST2 was measured by using a quantitative monoclonal ELISA assay. Results: LV mass index (β=0.337, P<0 .001, linear regression) was independently associated with sST2 concentrations. Increased sST2 was associated with an increased likelihood of LVH [Exp (B)=2.20, P=0.048, logistic regression] and increased systolic blood pressure [Exp (B)=1.02, P=0.05, logistic regression]. Comparing mean sST2 concentrations (adjusted for age, body mass index, gender) between different LV remodeling patterns, we found the greatest sST2 level in the group with concentric hypertrophy. There were no differences in sST2 concentration between groups with and without LV DD. Conclusions: Increased sST2 concentration in patients with MetS was associated with a greater likelihood of exhibiting LVH. Our results suggest that inflammation could be one of the principal triggering mechanisms for LV remodeling in MetS

Varijabilnost prinosa različitih sorti ozimog ječma

This paper presents the results of winter barley cultivars (Rekord, Grand, NS 565 and Nonijus). Varieties were grown in the experimental field of Agro-chemical school "Dr. Djordje Radic"-Kraljevo during two growing seasons. By examining the physical properties of grain, Nonijus was achieved the highest average yield in both growing seasons (4.140 t ha-1, 5.706 t ha-1). The significant difference in the significance between the impact of the year on grain quality in the examined barley varieties was significant for grain yield. The established differences in significance from the point of view of the genotype to the average values of grain yield were statistically not significant.U radu su prikazani rezultati ispitivanja ozimih sorti ječma (Rekord, Grand, NS 565 i Nonijus).
