abstract: methylenetetrahydrofolate reductase (mthfr) is a key enzyme regulating folate metabolism, which affects dna methylation and synthesis. one of the most important polymorphisms identified in the mthfr gene is c677t. mthfr activity is lowered in individuals with 677tt genotype. using pyrosequencing, we analyzed the mthfr genotypes in 118 colorectal cancer patients and 189 normal matched ...

We present the first-year data set of high-cadence, long-duration observations bright millisecond pulsar J0437?4715 obtained in Argentine Institute Radioastronomy (IAR). Using two single-dish 30 m radio antennas, we gather more than 700 hr good-quality with timing precision better 1 ?s. characterize white and red noise IAR’s observations, quantify effects scintillation, perform single-pulsar se...

conclusions association with sex, genotype and clinical symptoms revealed that the pre-s1 orf deletion occurred in 40% , 40%,and 20% of genotypes b,c, and d respectively, and 80% of the female population, of which all but one were diagnosed with chronic hepatitis b. additionally, several mutations were found in the bcp region with the following incidence rate; c1653 t (8.6%), a1752 g (10.8%),17...
