This study was carried out to determine the phytochemical profile and antioxidant activity of the carob. The results of preliminary phytochemical assessed showed that the alkaloid bases and salts, flavones aglycones, reducing compounds, fatty acids, polyterpenes, catechin tannins, volatile oils, cardiac glycosides, flavonoids, sterol glycosides and terpenes, amino acids and saponins are classes of chemical groups present in the pods of Ceratonia siliqua . The pods are characterized by 87 ± 1.0 % dry matter, 55 ± 0.2 % total sugars, 4 ± 0.1 % proteins, 7 ± 0.4 % lipids, 4 ± 0.3 ash.

Shoots, of pistachio trees sprayed with Epi–epibrassinolid and spermine, with three replicates. The hormonal treatments consisted of, 0.5 and 1 ppm Epi–Br and 100 and 200 ppm Spm and their combination. Some yield traits including inflorescence and fruit abscission were studied. Fruit abscission diminished significantly in all treatments in comparison with untreated hormonal trees. Epibrassinolid and spermine treatments decreased fruit blankness percentage and ethylene emission in compared with control. Simlutanouse application of epibrassinolid and spermine effectively raised split percentage in compared to each hormonal treatment alone. Chlorophyll content and carbohydrate content significantly increased by spermine 100 and 200 ppm, epibrassinolid 0.5 ppm and combination of spermine and epibrassinolid 0.5 in compared with the control. According to the results, it seems that spermine, epibrassinolid and combination of these hormones could significantly reduce fruit abscission and improve some of the physiological parameters in pistachio trees, probably through the antagonistic effects on ethylene production.

Genetic distances were estimated using three different molecular marker techniques including: start codon targeted (SCoT), conserved DNA–Derived Polymorphism (CDDP) and directly amplified minisatellite DNA (DAMD). According to the results, the average polymorphism information content was 0.37, 0.36, and 0.36 for SCoT, CDDP and DAMD markers, respectively indicating that the studied marker types were equal in terms of assessing diversity. Cluster analysis using SCoT and CDDP divided the varieties to four distinct clusters whereas DAMD markers data, grouped the varieties into three clusters. There was a positive significant correlation (r=0.92, p<0.01) between similarity matrix obtained by SCoT and CDDP. Results suggested that the efficiency of SCOT, CDDP and DAMD markers had a relatively same efficiency in fingerprinting of varieties. This is the first time that the efficiency of the three molecular markers have been compared with each other in a set of rose samples. The results showed that the studied markers had an appropriate polymorphism and thus were suitable for the study of genetic diversity in rose.

Regulations on the legally accepted amounts of heavy metals in food and in the body are very precise. The purpose of this paper was to evaluate the level of heavy metals in cow milk from different localities in the Baia Mare area, considered a very polluted area. The physical–chemical parameters and heavy metals in milk were determined. The determination of heavy metals in milk was performed by inductively coupled plasma mass spectrometry or ICP– MS used to identify and quantify the Pb, Cd, Cu, and Zn elements. The highest concentrations of Pb were observed in samples collected in Firiza locality with an average value of (43.22±0.62) (μg/L) and the lowest concentrations are for the samples analyzed in Săcălăşeni (11.53±0.33) (mg/L) (μg/L). Cd in milk did not show very large variations between localities, so the lowest concentrations were recorded in Săcălăşeni (4.32±0.13) and the highest ones were observed in the locality Firiza (10.93±0.39) (μg/L). The highest concentrations were observed for the Zn in milk, with an interval between (2255.20±7.14) (μg/L) in Săcălăşeni and (3855.80±5.11) (μg/L) for the analyzed samples from Firiza.

This research was conducted in the laboratory complexes in the school of pharmacy of Islamic Azad University Damghan Branch. Soil samples were collected from 3 different regions. Streaking plate was done and 9 colonies were selected on the basis of appearance. To identify isolates, biochemical tests were performed. 16SrRNA gene duplicated with PCR and sent to Sinagene Company for sequencing. All isolates were oxidase–negative and catalase–positive. The ONPG tests were negative. 16SrRNA analysis showed that the isolated bacteria belonged to genus Bacillus. The results confirmed that four bacterial isolates had alkaline protease production capacity.
