Although studies examining the biological roots of human behavior have been conducted since the seminal work Kahneman and Tversky, crises and panics have not disappeared. The frequent occurrence of various types of crises has led some economists to the conviction that financial markets occasionally praise irrational judgments and that market crashes cannot be avoided a priori (Sornette 2009; Sm...

What can we learn about aesthetics by studying the creative process of art-making? Much research has focused on the viewer’s relationship with the art-object. Analyzing this experience provides a quantitative approach, but such an approach, as Chatterjee (2011) describes, runs the risk of “looking for the dropped coin under the lamp because that is where things are visible. . . ” In this paper,...

Since the 1970s, after the seminal work of Rossmann and Argos (1978) comparing binding sites of known enzyme structures, the comparison and alignment of protein structures has come to be a fundamental and widely used task in computational structure biology. Three main steps are needed for comparing two protein structures: first, the detection of their common similarities; second, the alignment ...

The effect of neighbouring plants on crop root system architecture may directly interfere with water and nutrient acquisition, yet this important and interesting aspect of competition remains poorly understood. Here, the effect of the weed blackgrass (Alopecurus myosuroides Huds.) on wheat (Triticum aestivum L.) roots was tested, since a low density of this species (25 plants m-2) can lead to a...

the objective of this study was to investigate aspartate-amino-transferase (ast), γ-glutamyl-transferase(ggt), alkaline phosphatase (alp), lactate-dehydrogenase (ldh) and acid phosphatase (acp) activities andsemen parameters (volume, ph, concentration, total sperm number (tsn), progressive motility, dead sperm,total morphological defect (tmd) and hypo-osmotic swelling test (host)) in seminal pl...

two experiments were designed to examine the effects of crude seminal plasma (csp) exposure ofejaculated and epididymal spermatozoa before freezing. experiment 1, two consecutive ejaculates werecollected (n=4) within 5 min, the second one was carried out in a tube containing fiser extender (coatedspermatozoa); by centrifugation, seminal plasma was removed from coated ejaculates. the pellets wer...

Background: Vajikarana herbs from Ayurveda are known to enhance the sexual performance in folklore. The objective is to evaluate their effect by molecular and pharmacological screening. Materials and Methods: In the present study, the effect of four Vajikaran Rasayana herbs on penile erection, sperm count, seminal fructose content in vivo and nitric oxide (NO) release in vitro was assessed. Pen...

In order to determine calcium (Ca), magnesium (Mg) content and total antioxidant capacity (TAC) of seminal plasma in buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls; semen quality was evaluated, seminal plasma was then harvested by centrifugation and its Ca and Mg content were estimated and its TAC determined. The Ca ...
