Melatonin (ML) is an indolamine that regulates a wide range of physiological processes as growth roots and shoots, antioxidant enzyme activity, seed germination, photosynthetic efficiency promoting stress tolerance in plants, mitigating the harmful effects abiotic stress. Effects pretreatment soybean (Glycine max (L.) Merr.) seeds with 10, 30, 60 90 μM ML were evaluated seedlings under osmotic...

Until now it has been impractical to observe protein folding in silico for proteins larger than 50 residues. Limitations of both force field accuracy and computational efficiency make the folding problem very challenging. Here we employ discrete molecular dynamics (DMD) simulations with an all-atom force field to fold fast-folding proteins. We extend the DMD force field by introducing long-rang...

2 Fiber type and metabolic characteristics of lion (Panthera leo), caracal (Caracal caracal) and 3 human skeletal muscle 4 5 ABSTRACT 26 Lion (Panthera leo) and caracal (Caracal caracal) skeletal muscle samples from Vastus lateralis, 27 Longissimus dorsi and Gluteus medius were analyzed for fiber type and citrate synthase (CS), 3-28 hydroxyacyl Co A dehydrogenase (3HAD), phopshofructokinase (PF...

this study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mm nacl + cacl2 in 5:1 molar ratio) using four cvs, one british (madison) and three iranian cvs (7233-p12, 7233-p21 and 7233-p29). the plants were grown in a controlled greenhouse environment for about 18 weeks. a...

BACKGROUND Active surveillance (AS) is commonly used for men with low-risk prostate cancer (PCa). When life expectancy becomes too short for curative treatment to be beneficial, a change from AS to watchful waiting (WW) follows. Little is known about this change since it is rarely documented in medical records. OBJECTIVE To model transition from AS to WW and how this is affected by age and co...

The present study investigated the accumulation and depuration of two heavy metals Cd and Pb in the freshwater clam  (Corbicula fluminea) under laboratory conditions. Treated clams were exposed to single and combined treatments of Cd and Pb at the concentration of 5 mg L-1 and 10.5 mg L-1 for 10 days, respectively. The animals were then placed in metal free water for the following 5 days for de...

Phenotypic variances for linear and transformed weight traits were partitioned into residual, direct genetic (D) and maternal genetic (M) components using REML techniques with American Simmental Association data from calves born 1969 to 1985. Variance components were estimated separately from subclasses defined by sex (male, female) and percent Simmental (50, greater than or equal to 75). The m...
