There are generally four recognized classes of japonica rice cultivars grown in the lower region of the Yangtze River valley. The geographical distribution of the four classes is latitude-dependent. Variation for heading date (HD) among 29 japonica rice cultivars grown in the lower region of the Yangtze River valley and belonging to the four classes was characterized, and their sensitivity to v...

We derive an approximate intrapixel sensitivity variation (IPSV) of the IR-1 detector of WFC3 from ground-test imagery. The purpose was to assess whether additional testing of this sort should be performed in Thermal Vacuum 3 (TV3) testing, scheduled to commence in February 2008. Whereas NICMOS exhibits IPSV as large as 40%, peak to valley, in the photometry of stars observed in J band with the...

conclusions due to the increasing resistance of pathogens to usual empirical antibiotics, it is reasonable to stress upon preventive measures, so that a minimum number of neonates develop sepsis. results coagulase-negative staphylococci (cons) were the most prevalent pathogens isolated from blood specimens in early and late-onset disease. escherichia coli and klebsiella were the most causative ...

conclusions in conclusion, these results suggested a need for a switch to second line therapy regimens for treatment of infected patients in the iranian population. results helicobacter pylori infection was detected in 22 patients (22.92%). identity of the isolates was confirmed by pcr using glmm primers. chronic gastritis, duodenitis, intestinal metaplasia, dysplasia and cancer were detected a...

abstract background and aim: oral infections and dental caries are considered as two serious public health problems, which inflict a costly burden on health care services worldwide, especially in the developing countries. the aim of this study was to evaluate the antibacterial activity of iranian licorice aqueous root extract on lactobacillus acidophilus in comparison with chlorhexidine. materi...

visceral leishmaniasis (vl) is a zoonotic disease caused by leishmania species. dogs are considered to be the main reservoir of vl. a number of methods and antigen-based assays are used for the diagnosis of leishmaniasis. however, currently available methods are mainly based on direct examination of tissues for the presence of parasites, which is highly invasive. a variety of serological tests ...

the aim of the study was to determine the resistance patterns of pseudomonas aeruginosa isolates recovered from patients with surgical wounds in hospitals and also to investigate their epidemiological relatedness using molecular typing techniques. twenty pseudomonas sp. isolated from surgical wounds were subjected to antibiotic susceptibility testing by disk diffusion, plasmid profile, sds-page...

fasciolosis diagnosis, due to low sensitivity of coprological diagnostic method has been challenging for a long period. in this study, dot-elisa, one of the simplest and the most sensitive tests in this regard, was evaluated using excretory-secretory antigens of fasciola hepatica to diagnose human fasciolosis three groups consisting of patients infected with fasciolosis (n= 95), patients with o...

introduction: p. aeruginosa is an important multi-drug resistant (mdr) opportunistic pathogen in hospital-acquired infections. several methods based on dna analysis have been used for investigating genetic diversity of p. aeruginosa isolates. among them, rep‑pcr typing has been introduced as a rapid, low cost method with high discriminatory power. the aims of this study were to investigate geno...
