The somatostatin (SS), the SS mRNA, and the SS receptor contents were measured and compared in 25 human meningiomas. The SS tissue content, measured with radioimmunoassay, amounted to 2.89 +/- 0.82 pg/mg tissue (mean +/- SEM). The SS mRNA levels visualized by in situ hybridization using a 32P-labeled synthetic oligonucleotide probe were undetectable in all cases. SS receptors were measured with...

BACKGROUND Child physical abuse is an important cause of morbidity and mortality in young children. The skeletal survey (SS) is considered a mandatory part of the evaluation for suspected physical abuse in young children. Literature suggests that a follow-up SS performed 10 to 21 days after the initial SS can provide important additional information, but previous studies evaluating the follow-u...

Several CGHC motif-containing disulfide isomerases support thrombosis. We here report that endoplasmic reticulum protein 72 (ERp72), with 3 CGHC redox-active sites (ao, a, and a'), supports thrombosis. We generated a new conditional knockout mouse model and found that Tie2-Cre/ERp72fl/fl mice with blood and endothelial cells lacking ERp72 had prolonged tail bleeding times and decreased platelet...

To evaluate the clinical potential of high nitrogen nickel-free austenitic stainless steel (HNNF SS), we have compared the cellular and molecular responses of human umbilical artery smooth muscle cells (HUASMCs) to HNNF SS and 316L SS (nickel-containing austenitic 316L stainless steel). CCK-8 analysis and flow cytometric analysis were used to assess the cellular responses (proliferation, apopto...

Somatostatin (SS) and its analogs exert inhibitory effects on secretive and proliferative processes of various cells via high affinity SS receptors (SS-R). SS analogs bind with different affinity to the five cloned SS-R subtypes. Octreotide, an octapeptide SS analog, binds with high affinity to the SS-R subtype 2 (sst2). SS-R have been demonstrated in vivo and in vitro on cells from endocrine a...

The stimulatory effect of potassium depolarization upon somatostatin (SS) mRNA levels in primary cultures of fetal cerebrocortical cells was analyzed. Depolarizing stimuli, such as 56 mM K+ exposure for 30 min, elicited an increase in immunoreactive somatostatin (IR-SS) release to the media and decreased SS mRNA levels. These were increased when exposure to depolarization stimuli was prolonged ...

It is well known that TCP does not fully utilize the available bandwidth in fast long-distance networks. This paper proposes S-shaped TCP (SS-TCP). The window growth function of SS-TCP is, in the steady state condition, S-shaped, and it can be divided into three regions. In region I, the window growth rate of SS-TCP is the same as that of standard TCP (STD-TCP). In region II, the window of SS-T...
