Striated muscle contraction is initiated when, following membrane depolarization, Ca(2+) binds to the low-affinity Ca(2+) binding sites of troponin C (TnC). The Ca(2+) activation of this protein results in a rearrangement of the components (troponin I, troponin T, and tropomyosin) of the thin filament, resulting in increased interaction between actin and myosin and the formation of cross bridge...

BACKGROUND AND PURPOSE Detection of underlying tumor in patients with unknown-origin acute ICH may be difficult because acute hematoma may mask enhancement of tumor on postcontrast CT. We intended to investigate the clinical utility of DECT in differentiating tumor bleeding from pure ICH. MATERIALS AND METHODS Using a dual-source CT scanner, we obtained TNC single-energy and postcontrast DECT...

We investigate the impacts of spatial pricing for ride-sourcing services in a Stackelberg framework considering traffic congestion. In lower level, we use combined distribution and assignment approaches to explicitly capture interactions between drivers’ relocation, riders’ mode choice, all travelers’ routing decisions. upper single transportation network company (TNC) determines strategies min...

The effects of neocortical spreading depression (SD) on the expression of immunoreactive c-fos protein were examined within the superficial laminae of trigeminal nucleus caudalis (TNC), a brainstem region processing nociceptive information. KCl was microinjected into the left parietal cortex at 9 min intervals over 1 hr, and SD was detected by a shift in interstitial DC potential within adjacen...

This paper presents problems and solutions in developing Thai National Corpus (TNC). TNC is designed to be a comparable corpus of British National Corpus. The project aims to collect eighty million words. Since 2006, the project can now collect only fourteen million words. The data is accessible from the TNC Web. Delay in creating the TNC is mainly caused from obtaining authorization of copyrig...

The complete amino acid sequence of rabbit skeletal muscle troponin C (TnC) was determined from studies on overlapping peptides isolated from cyanogen bromide and tryptic digests. TnC was found to be a single polypeptide chain of 159 amino acid residues, including 2 residues of tyrosine and 1 each of cysteine, histidine, and proline. The amino end is acetylated, the calculated net charge at pH ...

Under optimal partitioning theory (OPT), plants preferentially allocate biomass to acquire the resource that most limits growth. Within this framework, higher root mass under low nutrients is often assumed to reflect an allocation response to build more absorptive surface. However, higher root mass also could result from increased storage of total nonstructural carbohydrates (TNC) without an in...
