Syringe-dispensed omega-3 lipid injectable emulsions should be stored under airtight refrigeration: A proposal for the efficient supply of unapproved precious lipid resources.

Background: Both fish-oil lipid injectable emulsion (FO-ILE) and mixed-oil lipid injectable emulsion (MO-ILE) are key components of parenteral nutrition and require importation into Japan, and they are easily oxidized after opening. Given the small daily volumes of these lipids dispensed in infants and children with intestinal failure (IF), the purpose of the study was to identify the optimal storage method.

Methods: Lipids were prepared in polypropylene syringes in the following manner: air-sealing and photoprotection, air-sealing only, photoprotection only, and uncovered.

High-Trough Plasma Concentration of Afatinib Is Associated with Dose Reduction.

Afatinib is used to treat non-small-cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutation as a second-generation EGFR-tyrosine kinase inhibitor (TKI). Early prediction of adverse effects based on the pharmacokinetics of afatinib enables support for quality of life (QOL) in patients with no change in efficacy. We examined the pharmacokinetic relationship between trough plasma concentration and adverse effects and evaluated the utility of measuring the trough plasma concentration of afatinib as the first EGFR-TKI treatment for NSCLC in a prospective multicenter study.

Nutritional Effect of Oral Supplement Enriched in ω-3 Fatty Acids, Arginine, RNA on Immune Response and Leukocyte-platelet Aggregate Formation in Patients Undergoing Cardiac Surgery.

The aim of the present study was to investigate the influence of a supplement enriched in ω-3 fatty acids on immune responses and platelet-leukocyte complex formation in patients undergoing cardiac surgery. Patients in the supplement group (n = 7) took a supplement enriched in ω-3 fatty acids (Impact(®)) in addition to a hospital diet for five successive days before surgery; those in the control group (n = 7) took only hospital diet and did not take Impact(®). Blood samples in both groups were collected at same time points.

Enhanced platelet responsiveness due to chilling and its relation to CD40 ligand level and platelet-leukocyte aggregate formation.

To investigate platelet responsiveness during cold storage of whole blood, we examined platelet aggregation, expression of CD40 ligand (CD40L) on platelets, the plasma levels of soluble form of CD40L (sCD40L) as well as platelet-leukocyte aggregates. Flow cytometry analysis was performed to investigate platelet-leukocyte aggregate formation using antibodies against CD42b and CD45 and platelet activation using antibodies against P-selectin and PAC-1. Blood samples were collected from healthy volunteers, patients with cardiovascular diseases, or both.

Thymidine phosphorylase inhibits the expression of proapoptotic protein BNIP3.

An angiogenic factor, thymidine phosphorylase (TP), confers resistance to apoptosis induced by hypoxia. We investigated the molecular basis for the suppressive effect of TP on hypoxia-induced apoptosis using Jurkat cells transfected with TP cDNA, Jurkat/TP, and a mock transfectant, Jurkat/CV. TP and 2-deoxy-d-ribose, a degradation product of thymidine generated by TP enzymatic activity, suppressed hypoxia-induced apoptosis.

Lovastatin inhibits bronchial hyperresponsiveness by reducing RhoA signaling in rat allergic asthma.

Recent studies revealed an importance of a monomeric GTP-binding protein, RhoA, in contraction of bronchial smooth muscle (BSM). RhoA and its downstream have been proposed as a new target for the treatment of airway hyperresponsiveness in asthma. Statins are known to inhibit the functional activation of RhoA via the depletion of geranylgeranylpyrophosphate.

Effects of atorvastatin and aspirin combined therapy on inflammatory responses in patients undergoing coronary artery bypass grafting.

This study was conducted to compare the effects of atorvastatin plus aspirin combined therapy on inflammatory responses, endothelial cell function, and blood coagulation system in patients undergoing coronary artery bypass grafting (CABG) to aspirin monotherapy. The patients were randomized into atorvastatin plus aspirin combined therapy group and aspirin monotherapy group. Reduced total cholesterol in the combined therapy group was found in a short term of medication for 14 days.

Evaluation of anti-platelet aggregatory effects of aspirin, cilostazol and ramatroban on platelet-rich plasma and whole blood.

To compare property in anti-platelet effects of aspirin (a cyclooxygenase inhibitor), cilostazol (a phosphodiesterase III inhibitor) and ramatroban (a specific thromboxane A2 receptor antagonist), we measured human platelet-rich plasma (PRP) aggregation induced by adenosine diphosphate (ADP), collagen and arachidonic acid, and whole blood (WB) aggregation induced by ADP. The release of P-selectin, transforming growth factor-beta 1, and the formation of thromboxane A2 in response to agonists were also investigated. Inhibitory effects of 100 micromol/l aspirin, 10 micromol/l cilostazol and 1 micromol/l ramatroban on 5 micromol/l ADP-induced PRP aggregation were similar.
