During the growth of five of ten primary tumors that were induced by 3-methylcholanthrene in BALB/cMk and BALB/cMk x C57BL/6 F mice, leukemoid reactions, char acterized by increase in number of granulocytes in periph eral blood, and splenomegaly were observed. However, no such reactions occurred in five C57BL/6 mice bearing primary tumors induced by 3-methylcholanthrene. The results of leukemoi...

Ordered mesoporous carbons (OMCs), obtained by nanocasting using ordered mesoporous silicas (OMSs) as hard templates, exhibit unique arrangements of ordered regular nanopore/nanowire mesostructures. Here, we used nanocasting combined with hot-pressing to prepare 10 wt% OMC/OMS/SiO2 ternary composites possessing various carbon mesostructure configurations of different dimensionalities (1D isolat...

BACKGROUND AND PURPOSE We examined the effects of a caspase-1 inhibitor, N-Ac-Tyr-Val-Ala-Asp-chloromethyl ketone (Ac-YVAD-CMK), on neurogenic pulmonary edema in the endovascular perforation model of subarachnoid hemorrhage (SAH) in mice. METHODS Ninety-seven mice were assigned to sham, SAH+vehicle, SAH+Ac-YVAD-CMK (6 or 10 mg/kg), and SAH+Z-Val-Ala-Asp-fluoromethylketone (Z-VAD-FMK, 6 mg/kg)...

Ordered mesoporous carbon (CMK-3) with different surface modifications is applied as a support for Fe-based catalysts in the Fischer-Tropsch to olefins synthesis (FTO) with and without sodium and sulfur promoters. Different concentrations of functional groups do not affect the size (3-5 nm) of Fe particles in the fresh catalysts but iron (carbide) supported on N-enriched CMK-3 and a support wit...

The crystal structure of Staphylococcus aureus cytidine monophosphate kinase (CMK) in complex with cytidine 5'-monophosphate (CMP) has been determined at 2.3 angstroms resolution. The active site reveals novel features when compared with two orthologues of known structure. Compared with the Streptococcus pneumoniae CMK solution structure of the enzyme alone, S. aureus CMK adopts a more closed c...

To utilize the high specific capacity of SnO2 as an anode material in lithium-ion batteries, one has to overcome its poor cycling performance and rate capability, which result from large volume expansion (∼300%) of SnO2 during charging-discharging cycles. Hence, to accommodate the volume change during cycling, SnO2 nanoparticles of 6 nm diameter were synthesized specifically only on the outer s...

A gene encoding a polypeptide of 25 kDa is located immediately upstream of the gene for ribosomal protein S1, rpsA. In high gene copy number, this gene, mssA, was previously found to suppress defects in smbA, which is now known to be identical to pyrH, encoding UMP kinase. We show here that the 25-kDa polypeptide comprises CMP kinase and propose that the gene be designated cmk. In a strain dele...

Through encounters with predators, competitors, and noxious stimuli, animals have evolved defensive responses that minimize injury and are essential for survival. Physiological adaptation modulates the stimulus intensities that trigger such nocifensive behaviors, but the molecular networks that define their operating range are largely unknown. Here, we identify a gain-of-function allele of the ...
