The present study reports a high-throughput screening method for the salt formation of amine-containing active pharmaceutical ingredients (APIs) based on fluorescence measurements. A free form amine API was alkynylated by a solid-vapor reaction using propargyl bromide, and a fluorescent compound was produced by a subsequent reaction using 9-azidomethylanthracene. In contrast, salts were inert to propargyl bromide; thus, no fluorescence was observed. Samples for salt screening were prepared by grinding haloperidol with various counter acids, and these mixtures were derivatized in a 96-well microplate to determine whether the salt formation had occurred between haloperidol and the counter acids...

BACKGROUND: Immune thrombocytopenic purpura (ITP) is commonly treated with intravenous immunoglobulin (IVIG). METHODS: We retrospectively evaluated whether pretreatment clinical and laboratory findings could predict the short- and long-term response to IVIG. RESULTS: Short-term response was estimated by platelet counts 2 weeks after IVIG, and long-term response was assessed by thrombocytopenia-free survival (TFS). TFS was defined as the probability of survival without treatment failure after initial IVIG, such as relapse, requiring additional therapeutic interventions, or progressing to chronic ITP...

Whereas evidence has accumulated that nonhuman animals have access to the strength of their memory trace, it is unclear whether such metamemory contains components, as proposed by Hampton (2005). We assessed whether capuchin monkeys could recognize details of memorized items using a delayed matching-to-sample task. We used compound stimuli separable into 2 dimensions, "what" and "where." Two monkeys were trained to memorize both "what" and "where" a sample was and answer both/either "what" and/or "where" the sample was depending on each task after a delay...

PURPOSE: We evaluated the utility of arterial spin labeling (ASL) imaging of tumor blood flow (TBF) for grading non-enhancing astrocytic tumors. MATERIALS AND METHODS: Thirteen non-enhancing astrocytomas were divided into high-grade (n = 7) and low-grade (n = 6) groups. Both ASL and conventional sequences were acquired using the same magnetic resonance machine. Intratumoral absolute maximum TBF (TBFmax), absolute mean TBF (TBFmean), and corresponding values normalized to cerebral blood flow (TBFmax and TBFmean ratios) were measured...

Human dental pulp cells (DPCs), adherent cells derived from dental pulp tissues, are potential tools for cell transplantation therapy. However, little work has been done to optimize such transplantation. In this study, DPCs were treated with fibroblast growth factor-2 (FGF2) for 5-6 consecutive serial passages and were transplanted into the injury site immediately after complete transection of the rat spinal cord. FGF2 priming facilitated the DPCs to promote axonal regeneration and to improve locomotor function in the rat with spinal cord injury (SCI)...

We found that the orally administered thermolysin digest of β-conglycinin exhibits antidepressant-like effects in tail suspension and forced swim tests in mice. A comprehensive peptide analysis of the digest using liquid chromatography/mass spectrometry was performed, and LSSTQAQQSY emerged as a candidate antidepressant-like peptide. Orally administered synthetic LSSTQAQQSY exhibited antidepressant-like effects at a dose of 0.3 mg/kg; therefore, we named the decapeptide soy-deprestatin. In contrast, intraperitoneally administered soy-deprestatin was ineffective...

Dengue fever remains underreported in Africa due to lack of awareness among healthcare providers, the presence of other febrile illnesses, and insufficient laboratory testing. We present a case of imported dengue fever from Burkina Faso to Japan, where an outbreak of dengue was reported on October 18, 2016. The phylogenetic analysis revealed that the isolate from our patient belonged to a distinct of sylvatic dengue viruses, suggesting that dengue viruses have been maintained in the mosquitoes and human cycles in Burkina Faso for more than 30 years...

BACKGROUND: Emerging techniques such as brain hypo-fractionated radiotherapy (HF-RT) involve complex cases with limited guidelines for plan quality and normal tissue tolerances. The purpose of the present study was to statistically parameterize irradiated volume independently of dose prescription, or margin to determine what spread in achievable irradiated volume one may expect for a given case. METHODS: We defined EXT as the total tissue within the external contour of the patient (including the target) and we defined BMP as the contour of the brain minus PTV...

Background: Yokukansan (YKS), a Japanese traditional herbal medicine for neurosis and insomnia, is speculated to be useful for perioperative psychiatric symptoms in cancer patients, but there exists little empirical evidence. This study provides preliminary data about the efficacy, feasibility, and side effects of YKS for the treatment of preoperative anxiety and postoperative delirium in cancer patients. Methods: We retrospectively reviewed the medical records of colorectal cancer patients who took YKS for preoperative anxiety, evaluating the following: (1) patient characteristics, (2) feasibility of taking YKS, (3) changes in preoperative anxiety based on the Clinical Global Impression (CGI) scale and Edmonton Symptom Assessment System-revised (ESAS-r-anxiety), (4) incidence of postoperative delirium and (5) YKS-related side effects...

Quantitative control of histones and histone variants during cell cycle is relevant to their epigenetic functions. We found that the level of yeast histone variant H2A.Z in the G2/M-phase is actively kept low by the ubiquitin proteasome system and SUMO-targeted ubiquitin ligases. Overexpression of H2A.Z induced defects in mitotic progression, suggesting functional importance of this quantitative control.
