The amygdala has a pivotal role in processing traumatic stress; hence, gaining control over its activity could facilitate adaptive mechanism and recovery. To date, amygdala volitional regulation could be obtained only via real-time functional magnetic resonance imaging (fMRI), a highly inaccessible procedure. The current article presents high-impact neurobehavioral implications of a novel imagi...
Evidence is presented that the regulation of the cytochrome P-450(C17 alpha) of the steroid-17 alpha-monooxygenase and of the cytochrome P-450(cscc) of the cholesterol-monooxygenase by human choriogonadotropin (hCG) in vivo is mediated by differential mechanisms in the adult rat testis. An initial down-regulation of the cytochrome P-450(C17 alpha) but not of the P-450(cscc) can be demonstrated....
The present issue focuses on the classic question of early vs. late selection and evaluates the current status of the perceptual load theory that has been offered as an intermediate solution. Several of the papers compare or contrast perceptual load with an alternative explanationperceptual dilution. The first group of papers report evidence that is inconsistent with the perceptual load theory ...
This study sought to compare the role of family functioning in self-worth and happiness of slow-paced individuals with Down syndrome in Tehran and Baku. The present research had a causal-comparative (ex post facto) design. The research population was comprised of adults with Down syndrome some of whom had the Alzheimer’s disease. Purposive sampling method was utilized and 40 adults with Down sy...
In Drosophila melanogaster, the process of oogenesis is initiated with the asymmetric division of a germline stem cell. This division results in the self-renewal of the stem cell and the generation of a daughter cell that undergoes four successive mitotic divisions to produce a germline cyst of 16 cells. Here, we show that shut-down is essential for the normal function of the germline stem cell...
A tree transformation is sensible if the size of each output tree is uniformly bounded by a linear function in the size of the corresponding input tree. Every sensible tree transformation computed by an arbitrary weighted extended top-down tree transducer can also be computed by a weighted multi bottom-up tree transducer. This further motivates weighted multi bottom-up tree transducers as suita...
materials and methods: in order to achieve this, recombinant plasmid harboring antisense sequences targeting both of pta and acka was assembled, after transfecting to the cells, its effects on the cell growth and acetate accumulation in the minimal media was assessed and compared with the control, the plasmid without antisense cassette, in presence and absence of iptg in escherichia coli bl21 (...
a significant portion of gross domestic production (gdp) in any country belongs to the transportation system. transportation equipment, in the other hand, is supposed to be great consumer of oil products. many attempts have been assigned to the vehicles to cut down greenhouse gas (ghg). in this paper a novel heuristic algorithm based on clark and wright algorithm called green clark and wright (...
