Dried Saliva Spot (DSS) as a Convenient and Reliable Sampling for Bioanalysis: An Application for the Diagnosis of Diabetes Mellitus.

This paper proposes the dried saliva spot (DSS) as a convenient sampling technique for bioanalysis. The analytical method with the DSS was used for the determination of D,L-lactic acid (D,L-LA) and the D/L ratio of diabetic patients and prediabetic persons for the simple screening of the disease. The D,L-LA in the DSS was labeled with a chiral reagent (DMT-3(S)-Apy) for carboxylic acids and determined by UPLC-ESI-MS/MS.

A novel approach for LC-MS/MS-based chiral metabolomics fingerprinting and chiral metabolomics extraction using a pair of enantiomers of chiral derivatization reagents.

Chiral metabolites are found in a wide variety of living organisms and some of them are understood to be physiologically active compounds and biomarkers. However, the overall analysis of chiral metabolomics is quite difficult due to the high number of metabolites, the significant diversity in their physicochemical properties, and concentration range from metabolite-to-metabolite. To solve this difficulty, we developed a novel approach for chiral metabolomics fingerprinting and chiral metabolomics extraction, which is based on the labeling of a pair of enantiomers of chiral derivatization reagents (i.

Profiling of chiral and achiral carboxylic acid metabolomics: synthesis and evaluation of triazine-type chiral derivatization reagents for carboxylic acids by LC-ESI-MS/MS and the application to saliva of healthy volunteers and diabetic patients.

Novel triazine-type chiral derivatization reagents, i.e., (S)-1-(4,6-dimethoxy-1,3,5-triazin-2-yl)pyrrolidin-3-amine (DMT-3(S)-Apy) and (S)-4,6-dimethoxy-N-(pyrrolidin-3-yl)-1,3,5-triazin-2-amine (DMT-1(S)-Apy), were developed for the highly sensitive and selective detection of chiral carboxylic acids by UPLC-MS/MS analysis.

Determination of acetone in saliva by reversed-phase liquid chromatography with fluorescence detection and the monitoring of diabetes mellitus patients with ketoacidosis.

Background: In diabetes mellitus (DM) patients with ketoacidosis, ketone bodies, i.e., acetone, acetoacetic acid (AA) and β-hydroxybutyric acid (HA), are increased in the blood and urine.

Changes in compliance with Japanese antiemetic guideline for chemotherapy-induced nausea and vomiting: a nationwide survey using a distributed research network.

Objective: Prophylaxis of chemotherapy (CT)-induced nausea and vomiting (CINV) is important for patient's quality of life and adherence to CT. Neurokinin receptor antagonist (NK1 antagonist) was marketed in Japan in December 2009 and the first guideline for antiemetics for CINV was released in May 2010 from Japan Society of Clinical Oncology (JSCO). We assessed changes in compliance with the JSCO guideline during the first 18 months from the launch of NK1 antagonist in Japan.

Infiltration of M1 macrophages into adipose tissue of ddY-H mice preceding spontaneous appearances of insulin resistance.

We have isolated insulin resistant mice (ddY-H mice) which are spontaneously induced at 12-weeks of age even if fed with the standard chow pellets. Since accumulated evidences have suggested that an appearance of insulin resistance is associated with obesity and a state of inflammation in adipose tissue, the present study investigated an appearance of macrophages in adipose tissue of ddY-H mice. Although ddY-H mice were fed the standard chow pellets ad libitam, increases in body weight, adipose tissue mass, and fat cell size were observed.

Simultaneous determination of DL-lactic acid and DL-3-hydroxybutyric acid enantiomers in saliva of diabetes mellitus patients by high-throughput LC-ESI-MS/MS.

A simultaneous determination method for the enantiomers of chiral carboxylic acids by the combination of ultraperformance liquid chromatography and mass spectrometry (UPLC-MS/MS) has been developed. (S)(+)-1-(2-Pyrrolidinylmethyl)-pyrrolidine (S-PMP) was used as the derivatization reagent for the high-throughput determination of biological chiral carboxylic acids, i.e.

A new diabetic mouse model derived from the ddY strain.

Selective breeding was used to isolate hyperglycemic (ddY-H) or normoglycemic (ddY-L) mice that had been induced by fasting and refeeding. Serum glucose levels 12 h after 48 h-fasting were high in male ddY-H mice, but relatively low in male ddY-L mice compared with control ddY mice. Glucose tolerance was impaired in ddY-H mice maintained with standard chow pellets ad libitum at 12 weeks of age, and serum glucose and insulin levels were significantly increased after overnight fasting at 15 weeks of age.

Combined antitumor effect of cyclophosphamide and bromodeoxyuridine in BDF1 mice bearing L1210 ascites tumors.

We investigated the combined effect of cyclophosphamide (CPA) and 5-bromo-2'-deoxyuridine (BrdUrd) both in mice bearing L1210 ascites tumors and in L1210 leukemic cells in vitro. Administration of BrdUrd (100 mg/kg) for 5 consecutive days before a single dose (80 mg/kg) of CPA significantly extended the survival of mice by 158%, compared with CPA alone. BrdUrd administered at daily doses of 100 or 200 mg/kg for 5 consecutive days did not extended the survival of mice.

[Roles of the hospital pharmacist and the cooperation between hospital pharmacy and insurance pharmacy in the introduction of home parenteral nutrition].

In the introduction of home parenteral nutrition (HPN), roles of the pharmacist are important from the viewpoint of drug therapy. In our hospital, patients are to be shifted to home medical care under the adequate guidance and proper adjustment by the cooperation between the clinical pharmacists and home medical care pharmacists. We are also enhancing the cooperation with the pharmacists in insurance pharmacies.
