Background: In Japan, hospitalization for the assessment of mentally disordered offenders under the Act on Medical Care and Treatment for the Persons Who Had Caused Serious Cases under the Condition of Insanity (the Medical Treatment and Supervision Act, or the MTS Act) has yet to be standardized.

Methods: We conducted a written survey that included a questionnaire regarding hospitalization for assessment; the questionnaire consisted of 335 options with 9 grades of validity for 60 clinical situations. The survey was mailed to 50 Japanese forensic mental health experts, and 42 responses were received.

In this study, two successive field trials were conducted during the non-breeding season to investigate various factors affecting on fertility of Suffolk ewes after intrauterine insemination with frozen-thawed semen. In the first year (Experiment 1), three sperm numbers per insemination dose (0.25, 0.

Objective: To investigate the mid-term effect of uterine artery embolization (UAE) on fertility after bilateral UAE with either tris-acryl gelatin microspheres (TAGM) or gelatin particles (GP).

Materials And Methods: Fertility was compared in 6 ewes that underwent UAE with TAGM, 6 ewes that underwent UAE with GP, and 6 control ewes. All ewes were artificially inseminated or naturally bred for 2 consecutive breeding seasons after UAE.

Objective: To investigate the influence of uterine artery embolization (UAE) on fertility after bilateral UAE with either tris-acryl gelatin microspheres (TAGM) or gelatin particles (GP).

Materials And Methods: Six ewes that underwent UAE with TAGM, 6 ewes that underwent UAE with GP, and 6 control ewes were compared. After hormonal synchronization of the menstrual cycle, artificial insemination (AI) was performed.

The aim of this study was to investigate the effects of the presence and the numbers of corpora lutea (CL) in porcine ovaries on in vitro oocyte maturation and embryonic development following intracytoplasmic sperm injection (ICSI). At oocyte collection, the ovaries of non-delivered and delivered pigs were classified into four groups by CL presence. The effect of the number of CL was also investigated following re-division of the non-delivered groups into four groups.

Article Synopsis
  • New environmental standards for zinc in Japan's surface waters were established in 2003, setting a target concentration of 0.03 mg/L to protect aquatic life.
  • A study conducted in 2005 aimed to assess zinc concentrations in wastewater effluent, finding that conventional treatment methods struggle to remove dissolved zinc, particularly when influent zinc levels are low.
  • As a result of the study, in 2006, effluent standards for wastewater treatment plants and industrial discharges were aligned at 2 mg/L to better control zinc pollution in public water bodies.

Two types of thermotropic smectic phase and of anisotropic ion conduction were observed in an amphiphilic ionic liquid, N-ethyl-N'-dodecylimidazolium dodecyl sulfonate/lithium tetrafluoroborate mixture.

We first succeeded in synthesizing ionic liquids from 20 natural amino acids. Amino acid ionic liquids dissolved native amino acids, despite water-free conditions. Furthermore, these ionic liquids are soluble in various organic solvents, such as chloroform.

Novel binary ionic liquids based on zwitterionic liquid and HTFSI for anhydrous proton transport were prepared and showed ionic conductivity of about 10(-2) S cm(-1) at 150 degrees C and a zwitterionic liquid content of 60 mol%.

We describe the behavior of the conductivity, viscosity, and vapor pressure of various binary liquid systems in which proton transfer occurs between neat Brönsted acids and bases to form salts with melting points below ambient. Such liquids form an important subgroup of the ionic liquid (IL) class of reaction media and electrolytes on which so much attention is currently being focused. Such "protic ionic liquids" exhibit a wide range of thermal stabilities.

A flexible self-standing film with layered nanostructures was obtained by in situ photopolymerization of a new smectic liquid-crystalline monomer containing a tetra(oxyethylene) moiety, which forms a macroscopically oriented complex with lithium salts. The resultant films show two-dimensional ionic conductivity.
