A 14-years-old squirrel monkey was euthanized due to weakness. Histopathological examination revealed multifocal growth of oval cells with severe atypia in the liver, spleen, and bone marrow. The neoplastic cells were positive for histiocytic markers (Iba1, HLA-DR, CD204).

Herein, aggregation-induced room-temperature phosphorescence (RTP) is observed from the crystals of trinuclear Au(I) complexes. The RTP is highly sensitive to the crystal structure, with a slight difference in the alkyl side chains causing not only a change in the crystal structure but also a shift in the RTP maximum.

The phosphorescence is emitted at room temperature and in the presence of air from crystals of trinuclear Au(I) complexes, accompanied by an extremely large Stokes shift of 2.2 × 10 cm (450 nm).

The Met1-linked linear ubiquitin chain, which is generated by linear ubiquitin chain assembly complex (LUBAC), is important for regulating NF-κB activation. This process occurs through the linear ubiquitination of NF-κB essential modulator, a regulatory subunit of the canonical inhibitor of the NF-κB kinase complex.

Methods: We performed a placebo-controlled double-blind crossover study involving 41 schizophrenia patients in which D-cycloserine 50 mg/day was added-on, and the influence of the onset age and association with white matter integrity on MR diffusion tensor imaging were investigated for the first time. The patients were evaluated using the Positive and Negative Syndrome Scale (PANSS), Scale for the Assessment of Negative Symptoms (SANS), Brief Assessment of Cognition in Schizophrenia (BACS), and other scales.
Autism spectrum disorder (ASD) is highly heritable and encompasses a various set of neuropsychiatric disorders with a wide-ranging presentation. HPC-1/syntaxin1A (STX1A) encodes a neuronal plasma membrane protein that regulates the secretion of neurotransmitters and neuromodulators. STX1A gene ablated mice (null and heterozygote mutant) exhibit abnormal behavioral profiles similar to human autistic symptoms, accompanied by reduction of monoamine secretion.

Recently it has been reported the Gln/Glu ratio is the most useful index, quantifying neuronal-glial interactions and the balance of glutamatergic metabolites In this MRS study, we elucidated the abnormalities of metabolites in a larger sample of patients with BD with a high-field MRI system.
Methods: Sixty-two subjects (31 patients with BD and 31 healthy controls [HC]) underwent 3T proton MRS (1H-MRS) of the anterior cingulate cortex (ACC) and left basal ganglia (ltBG) using a stimulated echo acquisition mode (STEAM) sequence.
Objective: Refeeding in patients with anorexia nervosa (AN) is associated with a risk of refeeding syndrome, which is a disruption in metabolism with a variety of features including hypophosphatemia. We evaluated the risk factors for refeeding hypophosphatemia (RH) during nutritional replenishment in Japanese patients with AN.
Methods: We retrospectively examined clinical data for 99 female inpatients (mean age 30.
Morphological and genetic analyses were performed on four avian species of the subfamily Capillariinae (Nematoda: Trichuridae), i.e., Capillaria anatis from chickens (Gallus gallus domesticus) in Japan and the Philippines, Baruscapillaria obsignata from chickens and captive swans (Cygnus olor and Cygnus atratus) in Japan, Capillaria pudendotecta from captive swans in Japan, and Capillaria madseni from carrion and jungle crows (Corvus corone and Corvus macrorhynchos) in Japan.

As a fundamental carrier for plasmid DNA or nucleic acids, we developed a liposomal nanoparticle (multifunctional envelope-type nano device [MEND]) containing a proton-ionizable amino lipid (YSK-MEND). Here we report on the impact of apolipoprotein E (ApoE) modification on the function of YSK-MEND in terms of targeting brain cells.

These NaFePO4 polymorphs assume orthorhombic frameworks (space group No. 62, Pnma), built from FeO6 octahedral and PO4 tetrahedral units having corner-sharing and edge-sharing arrangements.

The development of insulin resistance in hyperthyroidism has been documented. We investigated the relationship between IL-18 and insulin resistance in patients with hyperthyroid Graves' disease and in experimental hyperthyroid mice.

The extended π-system of the fused BODIPY induces near-infrared (NIR) absorption and strong π-π interactions in the solid state. These features are beneficial for the application of the dye as a functional material.

We developed a new method for measurement of the antioxidative activity of foods using the occurrence frequency of AP sites on DNA. Combined with the electron spin resonance (ESR) method as a standard method, we examined whether fish and soy sauces including puffer fish [Takifugu rubripes (Temminck et Schlegel)] sauce could protect DNA from damage caused by hydroxyl radicals.

The X-ray diffraction measurement has revealed that the crystals are oriented with the crystallographic c axis perpendicular to the field. The anisotropic diamagnetic susceptibility arising from the benzene rings has been estimated for the crystals along the principal magnetic chi 1, chi 2, and chi 3 axes.

We investigated serum total interleukin-12 (IL-12) levels in patients with Graves' disease and Hashimoto's thyroiditis. The serum IL-12 levels in Graves' disease were significantly increased in the hyperthyroid state, and were decreased during treatment with methimazole or propylthiouracil in accordance with the decline of free tri-iodothyronine (T(3)) levels, free thyroxine levels and thyroid-binding inhibiting immunoglobulin (TBII) levels. When T(3) was administered orally to normal subjects, serum IL-12 levels were slightly increased.

The lower classic PKC activity on pretreatment with phorbol ester (phorbol 12-myristate 13-acetate (PMA)) for 24 h markedly decreased IL-1beta-induced E-selectin mRNA expression in the presence of fetal calf serum and basic fibroblast growth factor, although the induction of ICAM-1 mRNA expression was only influenced a little by the PKC down-regulation. On the other hand, tumor necrosis factor-alpha (TNFalpha)-induced gene expression of these adhesion molecules was unaffected by such PKC modulation.

To isolate the interferon-inducible protein 10 (IP-10) receptor gene, we searched for cells that respond to IP-10. Among several human and murine T cell lines, only CTLL2 cells ( a murine cytotoxic T cell line) responded to IP-10 with transient elevation of intracellular Ca2+. The murine IP-10 receptor gene has been cloned from cDNA derived from CTLL2 cells using the reverse transcriptase-polymerase chain reaction protocol with two degenerate primers corresponding to conserved regions of chemokine receptors.
