TL;DR: Electron microscopic observation revealed that BDA-labeled boutons form asymmetric synapses mainly with small dendrites and dendritic spines that formed in the rat using the biotinylated dextran amine anterograde tracing method.

TL;DR: Sph-1-P, rather than LPA, is a major bioactive lysophospholipid that is released from platelets and interacts with endothelial cells, under the conditions in which critical platelet-endothelial interactions occur.

TL;DR: Skin cells represent a true target for the products of the serotoninergic/melatoninergic cutaneous pathway with their actions modulating cell proliferation or viability, according to cell type and culture conditions.
Abstract: We tested the expression of genes coding receptors of a cutaneous serotoninergic/melatoninergic system in whole human skin and in normal and pathologic cultured skin cells. Evaluation of serotonin (5HT), melatonin (MT), and melatonin-related receptors (MRR) showed expression of the isoforms 5HT2B, 5HT7, and MT1 genes in almost all the tested samples. Expression of other isoforms was less prevalent; 5HT2C, MRR, and MT2 were rarely detected. We also found novel isoforms for MT2, MRR, and 5HT2B and documented the process of RNA editing for 5HT2C. Testing for functional activity of these receptors with serotonin and melatonin (10(-14) to 10(-10) M) showed variable effects depending on cell type and culture conditions. Thus, serotonin stimulated proliferation of melanocytes in medium deprived of growth factors, while inhibiting cell growth in the presence of growth factors. Melatonin inhibited both apoptosis of HaCaT keratinocytes incubated in serum-free media, and proliferation of cells cultured in medium supplemented with serum. Melatonin also increased the numbers of viable fibroblasts incubated in serum free medium. N-acetylserotonin (NAS) and 5 methoxytryptamine (5MTT) were generally without effect on cell proliferation, with the exception of an inhibition of melanocyte proliferation at the higher 5MTT concentration of 10(-10) M. Thus, skin cells represent a true target for the products of the serotoninergic/melatoninergic cutaneous pathway with their actions modulating cell proliferation or viability.

TL;DR: The absence of significant myelosuppression and encouraging clinical responses suggest compellingly that irinotecan be further evaluated in children using the (qd x 5) x 2 schedule, beginning at a dose of 20 mg/m(2).
Abstract: PURPOSE: In a preclinical model of neuroblastoma, administration of irinotecan daily 5 days per week for 2 consecutive weeks ([qd × 5] × 2) resulted in greater antitumor activity than did a single 5-day course with the same total dose. We evaluated this protracted schedule in children. PATIENTS AND METHODS: Twenty-three children with refractory solid tumors were enrolled onto a phase I study. Cohorts received irinotecan by 1-hour intravenous infusion at 20, 24, or 29 mg/m2 (qd × 5) × 2 every 21 days. RESULTS: The 23 children (median age, 14.1 years; median prior regimens, two) received 84 courses. Predominant diagnoses were neuroblastoma (n = 5), osteosarcoma (n = 5), and rhabdomyosarcoma (n = 4). The dose-limiting toxicity was grade 3/4 diarrhea and/or abdominal cramps in six of 12 patients treated at 24 mg/m2, despite aggressive use of loperamide. The maximum-tolerated dose (MTD) on this schedule was 20 mg/m2/d. Five patients had partial responses and 16 had disease stabilization. On day 1, the median s...

TL;DR: Results indicate that PLGA-CUR NPs efficiently internalize in prostate cancer cells and release biologically active CUR in cytosolic compartment of cells for effective therapeutic activity and can significantly accumulate and exhibit superior anticancer activity in prostatecancer.
