Background: Acute leukemia is the prevalent malignancy in pediatrics. One of the most important causing factors of acute lymphoblastic leukemia is mutations of proto oncogenes and their chang in to oncogenes. Activation of N-RAS proto-oncogene due to point mutations plays a major role in ALL malignancy. Since there was no report on the frequency of N-RAS gene mutation in Iranian pediatric AL...
ABSTRACT We report the first detection in JK = 10–00 rotational transition line of CH3D towards three Class 0/I proto-brown dwarfs (proto-BDs) from IRAM 30-m observations. Assuming a temperature 25 K, abundances (relative to H2) are range (2.3–14.5) × 10−7. The CH4 derived and assuming DCO+/HCO+ ratios (0.05–4.8) 10−5. gas-phase formation via CH2D+ is enhanced at high densities 108–1010 cm−3 ou...
It is often claimed that Kripke (1980) and Putnam (1975) established that many predicates, most importantly natural kind predicates, are like proper names in being rigid designators. This insight is generally regarded as having important consequences in the theory of necessary truths: the rigidity of terms such as 'Hesperus', 'Phosphorus', 'water' and 'H 2 O' is used in explaining why identity ...
A total 7 species and 13 genera of marine gastropod assemblages are reported for the first time from the Varehh Zard section (Asmari Formation), north of Pole Dokhtar, Lorestan Basin. The section under study, the Asmari Formation, lies between the Shahbazam Formation at the base and Gachsaran Formation at the top. According to the distribution of index foraminifera, the Asmari Formation is Earl...
