Gibberellic acid (GA) promotes seed germination, elongation growth, and flowering time in plants. GA responses are repressed by DELLA proteins, which contain an N-terminal DELLA domain essential for GA-dependent proteasomal degradation of DELLA repressors. Mutations of or within the DELLA domain of DELLA repressors have been described for species including Arabidopsis thaliana, wheat (Triticum ...

Cyclodextrin-inclusion complexes (CD-ICs) possess great prominence in food and pharmaceutical industries due to their enhanced ability for stabilization of active compounds during processing, storage and usage. Here, CD-IC of gallic acid (GA) with hydroxypropyl-beta-cyclodextrin (GA/HPβCD-IC) was prepared and then incorporated into polylactic acid (PLA) nanofibers (PLA/GA/HPβCD-IC-NF) using ele...

اغلب لندفرم های سطح زمین به آرامی و طی هزاران یا میلیون ها سال تکامل می یابند. از آن جا که تغییرات لندفرم ها در مقیاس عمر بشر قابل تشخیص نمی باشند، ارزیابی شواهد ژئومورفولوژیک می تواند نقش مهمّی در شناسایی حرکات تکتونیکی مناطق ایفا کند. رودخانه ها و شبکه زهکشی از جمله مهم ترین عوارضی هستند که نسبت به تغییرات زمین ساختی بسیار حسّاس می باشند. جهت بررسی تأثیر تکتونیک های فعّال بر مورفومتری شبکه زهکشی...

The triblock 18β-glycyrrhetinic acid-poly(ethylene glycol)18β-glycyrrhetinic acid conjugates (GA-PEG-GA) based self-assembled micelles were synthesized and characterized by FTIR, NMR, transmission electron microscopy, and particle size analysis. The GA-PEG-GA conjugates having the critical micelle concentration of 6 × 10(-5) M were used to form nanosized micelles, with mean diameters of 159.21 ...

Gibberellins (GAs) are plant hormones that promote a wide range of developmental processes. While GA signalling is well understood, little is known about how GA is transported or how GA distribution is regulated. Here we utilize fluorescently labelled GAs (GA-Fl) to screen for Arabidopsis mutants deficient in GA transport. We show that the NPF3 transporter efficiently transports GA across cell ...

GENE_ARCH is an evolution-based Generative Design System that uses adaptation to shape energy-efficient and sustainable architectural solutions. The system applies goal-oriented design, combining a Genetic Algorithm (GA) as the search engine, with DOE2.1E building simulation software as the evaluation module. The GA can work either as a standard GA or as a Pareto GA, for multicriteria optimizat...

AIM To determine the possibility that diabetes mellitus promotes pancreatic ductal adenocarcinoma via glyceraldehyde (GA)-derived advanced glycation-end products (GA-AGEs). METHODS PANC-1, a human pancreatic cancer cell line, was treated with 1-4 mmol/L GA for 24 h. The cell viability and intracellular GA-AGEs were measured by WST-8 assay and slot blotting. Moreover, immunostaining of PANC-1 ...

Hydrogen plays an essential role during the in situ assembly of tailored catalytic materials, and serves as key ingredient in multifarious chemical reactions promoted by these catalysts. Despite intensive debate for several decades, the existence and nature of hydrogen-involved mechanisms - such as hydrogen-spillover, surface migration - have not been unambiguously proven and elucidated up to d...

Barley endosperm halves release acid phosphatase in response to several gibberellins and gibberellin precursors. Seed halves incubated with 10(-7)m GA(3) at 29 degrees begin to release phosphatase after 11 hr and release it for another 26 hr in response to GA(3). After 37 hr, the rate of release slows to that of seed halves incubated without GA(3). GA(3) is active at 10(-10)m and maximally acti...

We report on electrical measurements of the effective density of states in the ferromagnetic semiconductor material (Ga,Mn)As. By analyzing the conductivity correction to an enhanced electron-electron interaction the electrical diffusion constant was extracted for (Ga,Mn)As samples of different dimensionality. Using the Einstein relation allows us to deduce the effective density of states of (G...
