Objective: To compare follicular fluid and serum concentrations of anti-Mullerian hormone (AMH) as predictors of the outcome of assisted reproduction.
Study Design: This observational study enrolled 58 women who were undergoing IVF or ICSI treatment with the long stimulation protocol. Patients diagnosed as having PCOS were excluded.
We report on an 8-year-old boy with non-paraneoplastic anti-NMDA receptor (NMDAR) encephalitis, who presented with psychotic symptoms and involuntary movement following an intractable seizure. His serum and CSF tested positive for anti-NMDAR antibodies. He received an initial immunotherapy consisting of methylprednisolone pulse therapy (mPSL) and intravenous immunoglobulin therapy (IVIg), without any clinical improvement.

The phosphate-terminated branch of PEG was synthesized via a substitution reaction of the hydroxyl end groups using phosphoryl chloride. The gelation and gel properties including rheological properties can be tuned by the careful selection of metal ions, branch numbers, and temperature.

One year later, her primary symptom changed to bloody diarrhea. The colonoscopic and histological findings were consistent with the characteristics of cap polyposis.

In the human thrombopoietin receptor (TpoR), a unique amphipathic RWQFP motif separates the transmembrane (TM) and intracellular domains. Using a combination of mutagenesis, spectroscopy, and biochemical assays, we show that W515 of this motif impairs dimerization of the upstream TpoR TM helix.

Evidence for the role of these regions in the mechanism of receptor dimerization and activation is provided by TM-JM peptides corresponding to the Neu (or rat ErbB2) receptor. Solid-state NMR and fluorescence spectroscopy show that there are tight interactions of the JM sequence with negatively charged lipids, including phosphatidylinositol 4,5-bisphosphate, in TM-JM peptides corresponding to the wild-type receptor sequence.

An anion complex composed of (H2O)6(-) and benzene, Bz·(H2O)6(-), is formed via the reaction of (H2O)6(-)Arm with benzene. The reaction proceeds as an Ar-mediated association process such that a rapid energy dissipation by sequential Ar evaporation efficiently suppresses the thermionic emission of e(-), H2O, or both, giving rise to the formation of Bz·(H2O)6(-).

Thus, IL-10- and M-CSF-rich conditions in colonic tissues seem to contribute to the improvement of pathological conditions in patients with inflammatory bowel diseases (IBD). We have already reported that ulinastatin, a serine protease inhibitor, increases M-CSF production during granulocyte/monocyte (GM) adsorption to cellulose acetate (CA) beads (carriers for Adacolumn therapy).

This multicolor pump-probe scheme can provide us with a powerful experimental tool for investigating a variety of wave packets evolving with a time scale of ~20 fs.

The recent discovery of MLL2 as a causative gene of Kabuki syndrome has enabled the extreme end of the phenotype to be explored. We herein report on two patients with striking visible congenital staphyloma at birth.

In this study, the proliferative patterns and kinetics of donor-derived GFRα1-positive spermatogonia containing potential SSCs were examined during early colonization following spermatogonial transplantation.
Results: Donor-derived GFRα1-positive cells frequently formed several aggregates of A(al(aligned)) /morula-like structures in a single spermatogenic cell patch before and on day 14 post-transplant, indicating a possible involvement in the formation of a stable spermatogenic colony at 21 days post-transplant.
This article reports the first case of a Japanese girl with molecularly confirmed Myhre syndrome (MS). The patient was 9 years old at her first visit, and she had been diagnosed with unknown skeletal dysplasia. Her phenotype fulfilled the clinical and radiological criteria for MS, such as typical facies with prognathism, hearing impairment, short stature, square body shape, and limited joint mobility.

β-1,4-Galactosyltransferase (β-1,4-GalT) V - whose human and mouse genes were cloned by us - has been suggested to be involved in the biosyntheses of N-glycans, O-glycans, and lactosylceramide by in vitro studies. Our recent study showed that β-1,4-GalT V-knockout mice are embryonic lethal, suggesting the importance of the glycans synthesized by β-1,4-GalT V for embryonic development. A subsequent study showed that murine β-1,4-GalT V is involved in the biosynthesis of lactosylceramide.

The crystal form of Pt(12F(2)PPy)acac was successfully determined to be triclinic by single-crystal X-ray structural analysis. The molecules were parallelly aligned in the unit cell.

The principal sources of these outbreaks are contaminated growth hormone (226 cases) and dura mater grafts (228 cases) derived from human cadavers with undiagnosed CJD infections; a small number of additional cases are caused by neurosurgical instrument contamination, corneal grafts, gonadotrophic hormone, and secondary infection with variant CJD transmitted by transfusion of blood products. No new sources of disease have been identified, and current practices, which combine improved recognition of potentially infected persons with new disinfection methods for fragile surgical instruments and biological products, should continue to minimize the risk for iatrogenic disease until a blood screening test for the detection of preclinical infection is validated for human use.

Aim: In Japan, it is rare for patients to confirm their intentions regarding terminal care treatment in hospital by signature. To maintain respect for the autonomy of elderly patients, we encouraged confirmation by signature regarding terminal care treatment in elderly patients, after repeated discussions. The purpose of this study was to clarify the status of confirmation of intention by signature.

Aims: Patients with intractable disease require long-term treatment and experience repeated bouts of progressive symptoms and resolutions, which cause them severe suffering. The aim of this study was to elucidate the concepts of self-transcendence and subjective well-being in patients with intractable disease.
Methods: Forty-four patients with intractable disease (men/women: 22/22) participated.
Background And Aims: In mammalian spermatogenesis, glial cell line-derived neurotrophic factor (GDNF) is one of the major Sertoli cell-derived factors which regulates the maintenance of undifferentiated spermatogonia including spermatogonial stem cells (SSCs) through GDNF family receptor α1 (GFRα1). It remains unclear as to when, where and how GDNF molecules are produced and exposed to the GFRα1-positive spermatogonia in vivo.
Methodology And Principal Findings: Here we show the cyclical and patch-like distribution of immunoreactive GDNF-positive signals and their close co-localization with a subpopulation of GFRα1-positive spermatogonia along the basal surface of Sertoli cells in mice and hamsters.

The purpose of this study is to suggest a numerical model for postural control ability variations in children, young adults and the elderlies. Three sensors were attached to the subjects' bodies at the vertex, the iliospinale and the mid-patellar to measure three-dimensional acceleration at each point while subjects maintained a standing posture for two minutes. Variations in acceleration at the vertex differed among the three age groups.

Thus, M-CSF-rich conditions in colonic tissues seem to contribute to the improvement of pathological conditions in patients with inflammatory bowel diseases (IBD). However, it has not been clarified whether current therapies for IBD, including granulocyte/monocyte adsorptive apheresis using an Adacolumn, and ulinastatin, a serine protease inhibitor, affect the production of M-CSF.

By calculating the excitation spectrum and potential energy surface, we found that the PIPT of TTF-CA crystal may proceed through the angle change of the molecular planes. We also found that the CT excitation of one TTF-CA pair helps other neighboring TTF-CA pairs to become excited.
