Fms-like tyrosine kinase 3 (FLT3) performs a vital role in the pathogenesis of hematopoietic malignancies. Therefore in recent times, the focus of several studies was on use of FLT3 as a prognostic marker. The present study investigated the molecular characterization and incidence of FLT3 mutations in acute leukemia patients in Pakistan. A total of 55 patients were studied, of which 25 were suffering from acute lymphoblastic leukemia (ALL) and 30 were suffering from acute myeloid leukemia (AML). The polymerase chain reaction demonstrated FLT3/ITD mutations in 1 (4%) of 25 ALL patients, a male with the L2 subtype. In AML cases the rate was 4 (13.3%) of 30, three males and one female. The AML-M4 subtype was found in three and the AML M2 subtype in the other. In the AML cases, a statistically significant (p=0.009) relationship was found between WBC (109/L) and FLT3/ITD positivity. However, no significant relationship was found with other clinical parameters (p>0.05). In acute myeloid leukemia (AML) $FLT3/ITD^+$ mutation was more prevalent in elderly patients 31-40 age groups, 21-30 and 51-60 age groups respectively. In acute lymphoblastic leukemia (ALL) statistically no significant relationship was found between clinical features and FLT3/ITD positivity (p>0.05). However, in acute lymphoblastic leukemia (ALL) $FLT3/ITD^+$ mutation was more commonly found in age groups of 21-30.

Plant growth and productivity are greatly affected by environmental stresses such as dehydration, high salinity, low temperature and pathogen infection. Plant adaptation to these environmental stresses is controlled by cascades of molecular networks. The dehydration-responsive element-binding (DREB) transcription factors play an important role in the response of plants to environmental stresses by controlling the expression of many stress-related genes. They specifically interact with C-repeat/DRE (A/ GCCGAC) sequences present in the promoter regions of target genes. One of the DREB1 cDNA was previously cloned and overexpressed in transgenic potato plants. These transgenic plants displayed an improved tolerance to high salinity and drought stresses. The StDREB1 factor belongs to A-4 group that seem to be involved in biotic stress response. This report investigates the effect of Fusarium solani infection on the StDREB1 transgenic lines. Since a number of pathogenesis-related (PR) proteins are considered as DREB1 target genes, the expression of PR2, PR9 and PR3 genes were tested under biotic stress conditions. The β-1,3-glucanase (PR2) was specifically induced upon infection, whereas the chitinase and the peroxydase were expressed constitutively. The data also show that high levels of DREB1 transcripts accumulated rapidly when wild-type and transgenic plants were infected by F. solani. DREB1 transgenic potato plants accumulated higher levels of pathogenesis-related gene transcripts, such as PR2. These results showed that StDREB1 plays an important role in response to fungal attack in potato.
Comedia sin titulo de Garcia Lorca: ensayo dramatizado para una didactica inconclusa

Este articulo supone el analisis de Comedia sin titulo -una de las piezas inacabadas de Federico Garcia Lorca-, obra en la que observamos lenguajes ideologicos con los que el autor expresa su vision de la vida tanto dentro como fuera de la escena. El dramaturgo, en este auto alegorico de la revolucion, comparte sus didascalias con los lectores/espectadores mediante un ensayo dramatico: Lorca(maestro) comunica a su audiencia(discipulos) una didactica pronunciada, principalmente, a traves de las palabras de AUTOR. Comedia sin titulo articula las instrucciones para la comprension de la nueva verdad; asimismo, con este alegato liturgico, creemos que Lorca investiga sobre las nuevas tendencias escenicas y manifiesta su deseo de renovacion social.

This paper presents a fast Time Difference of Arrival (TDOA) estimation for sound source localization. TDOA is the time difference between the arrival times of a signal at two sensors. We propose a partial cross correlation method to increase the speed of TDOA estimation for sound source localization. We do this by predicting which part of the cross correlation function contains the required TDOA value with the help of the signal energies, and then we compute the cross correlation function in that direction only. Experiments show approximately 50% reduction in the cross correlation computation time thereby increasing the speed of TDOA computation. This makes it very relevant for real world surveillance.

The reduction in atmospheric inputs of SO42- as a result of stricter regulations of sulfur emission and the depletion in sulfur reserves following the intensification of agricultural production has caused a serious decrease in soil S-concentration. This would markedly affect growth and quality of numerous economically important plants. Foeniculum vulgare or fennel is one of the most cultivated aromatic and medicinal plants, mostly used for their powerful therapeutic effects. Being one of the cultivated species, Foeniculum vulgare could be affected by environmental disturbances like sulfur deficiency. In this work, the poor sulfur supply had a serious impact on the therapeutic quality of fennel seed extracts. At the application of sulfur deficiency, total phenolic compounds of fennel seeds extract decreased by 30% and their total antioxidant activity decreased by 21%. Sulfur starvation also reduced the antibacterial activity of fennel seeds against Staphylococcus aureus, Enterococcus faecalis, and Pseudomonas aeruginosa by increasing the MIC of seed extracts.

We present a novel process to fabricate three-dimensional (3D) metallic patterns from 3D printed polymeric structures utilizing different hygroscopic swelling behavior of two different polymeric materials. 3D patterns are printed with two different polymers as cube shape. The surface of the 3D printed polymeric structures is plated with nickel by an electroless plating method. The nickel patterns on the surface of the 3D printed cube shape structure are formed by removing sacrificial layers using the difference in the rate of hygroscopic swelling between two printing polymer materials. The hygroscopic behavior on the interfaced structure was modeled with COMSOL Multiphysics. The surface and electrical properties of the fabricated three-dimensional patterns were analyzed and characterized.
