We herein report familial defects in the molecular structure of luteinizing hormone (LH). The propositus was a 29-year-old women with repeated abortion in whom the serum LH concentration was extremely low determined by an immunoradiometric assay utilizing two monoclonal antibodies for the intact LH dimer and beta-subunit of LH (SPAC-S kit). Further studies on the serum LH concentration in this ...
We have developed a xylose-dependent expression system for tight and modulated expression of cloned genes in Bacillus subtilis. The expression system is contained on plasmid pSWEET for integration at the amyE locus of B. subtilis and incorporates components of the well-characterized, divergently transcribed xylose utilization operon. The system contains the xylose repressor encoded by xylR, the...
A global mechanism of catabolite repression of the genus Bacillus comprises negative regulation exerted through the binding of the CcpA protein to the catabolite-responsive elements (cres) of the target genes. We searched for cre sequences in the Bacillus subtilis genome using a query sequence, WTGNAANCGNWNNCW (N and W stand for any base and A or T, respectively), picking out 126 putative and k...
Despite the impact of DEC-MDPs over the past decade, scaling to large problem domains has been difficult to achieve. The scale-up problem is exacerbated in DEC-MDPs with continuous states, which are critical in domains involving time; the latest algorithm (M-DPFP) does not scale-up beyond two agents and a handful of unordered tasks per agent. This paper is focused on meeting this challenge in c...
the purpose of this study was to examine the status of supervision on departments’ heads at ferdowsi university of mashhad (fum) and realize some applied themes to provide a fit model for supervising departments’ heads in fum. the method was case study under a research category aimed for applied one. using purposive sampling, interviews were conducted with top fum managers, head departments, an...
the following question poped up: is there any relationship between iranian high school efl learners reading comprehension and listening comprehension? then the following null hypothesis (ho) was developed to the test the above, mentioned question. "there is no relationship between high school efl learners reading comprehension and listening comprehension. for nearly 16 weeks, the experimental g...
Understanding plant water stress (PWS) in the soil-plant-atmosphere-continuum (SPAC) that connects supply from soil, demand atmosphere, and self-regulation is a prerequisite for efficient irrigation response to scarcity. Currently, PWS can be defined various ways, example, based on environmental factors and/or plant-centric metrics. The environment-based metrics usually do not take plants into ...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...

we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
