Yasushi Shimada, Laurence Chow, Shozo Takagi, Junji Tagami
A previously reported, premixed calcium phosphate cements (CPC) forms hydroxyapatite (HA) as the only product, but had a setting time greater than 60 min. This study investigated properties of fast-hardening HA-forming premixed CPCs. All cements consisted

Extracellular and Intracellular Chorismate Mutases From Mycobacterium tuberculosis H 37 R v : Characterization of the Hypothetical Gene Products Rv1885c and Rv0948c

Two ORFs Rv1885c and Rv0948c from the genome of Mycobacterium tuberculsosis H37Rv were identified as putative chorismate mutases. We reported earlier that Rv1885c is indeed a chorismate mutase (CM) with a 33 amino acid cleavable signal sequence in a

Abstract Observational and experimental studies report associations between gestational phthalate exposure and fetal development, yet few data exist to characterize phthalate effects on head circumference (HC) or to estimate the impact of race or sex. To
