xanthan gum is an extracellular polysaccharide produced by various xanthomonas species such as x. campestris . the objective of present study was to investigate the influence of different carbon and nitrogen sources on xanthan gum production by x. campestris . using an experimental response surface methodology (rsm) complemented with a central composite design (ccd), the impact of peptone, lact...

Background: Genistein (GEN), a naturally occurring flavonoid present in soy bean, has attracted scientific interest for its possible benefits in cancer. Objective: The potential immunomodulatory effects of genistein on the immune system and against TC-1 tumor cell line were evaluated in adult female C57BL/6 mice. Methods: Mice were treated with GEN 10 days before to 10 days after the tumor indu...

This engineering brief describes HULTI-GEN (Huddersfield Universal Listening Test Interface Generator), a Cycling ‘74 Max-based tool. HULTI-GEN is a user-customisable environment, which takes user-defined parameters (e.g. the number of trials, stimuli and scale settings) and automatically constructs an interface for comparing auditory stimuli, whilst also randomising the stimuli and trial order...

fraction of the corresponding mean frequency. For the different individuals the amount of deviation is about the same. The critical termal increment, ,u, is in this case 12,200 calories. This agrees quantitatively with the increment for a number of other activities among arthropods' in which "nerve center" activity may be presumed to be the determining phenomenon. Our purpose now, however, is n...

  Abstract  Introduction: Intracerebroventricular (ICV) injection of streptozotocin (STZ) causes cognitive impairment in rats. The beneficial effect of genistein (GEN) was investigated on ICV STZ-induced learning, memory, and cognitive impairment in male rats. Methods: For this purpose, rats were injected with ICV STZ bilaterally, on days 1 and 3 (3 mg/kg). The STZ-injected rats received GEN (1...

‎in this paper we introduce the concept of order difference interval graph $gamma_{odi}(g)$ of a group $g$‎. ‎it is a graph $gamma_{odi}(g)$ with $v(gamma_{odi}(g)) = g$ and two vertices $a$ and $b$ are adjacent in $gamma_{odi}(g)$ if and only if $o(b)-o(a) in [o(a)‎, ‎o(b)]$‎. ‎without loss of generality‎, ‎we assume that $o(a) leq o(b)$‎. ‎in this paper we obtain several properties of $gamma_...
