Non-homogeneous distribution of steroids in fecal pellets: An example in brown brocket deer (Mazama gouazoubira) with progesterone metabolites.

Measuring reproductive hormones in feces has become an important tool in the endocrine characterization of wild animals' reproduction. However, several factors may influence its success, such as fecal collection and storage techniques, knowledge of steroid hormone metabolism, the extraction procedure, immunoassay selection, inherent factors, and the distribution of steroid hormones in the feces. It is known that the distribution of these hormones in the feces is not homogeneous, and prior to the extraction of the steroidal metabolites, homogenization of the feces is recommended.

Detection of Fine Radiographic Progression in Finger Joint Space Narrowing Beyond Human Eyes: Phantom Experiment and Clinical Study with Rheumatoid Arthritis Patients.

The visual assessment of joint space narrowing (JSN) on radiographs of rheumatoid arthritis (RA) patients such as the Genant-modified Sharp score (GSS) is widely accepted but limited by its subjectivity and insufficient sensitivity. We developed a software application which can assess JSN quantitatively using a temporal subtraction technique for radiographs, in which the chronological change in JSN between two radiographs was defined as the joint space difference index (JSDI). The aim of this study is to prove the superiority of the software in terms of detecting fine radiographic progression in finger JSN over human observers.

Cytokinesis D is Mediated by Cortical Flow of Dividing Cells Instead of Chemotaxis.

Cytokinesis D is known as the midwife mechanism in which neighboring cells facilitate cell division by crossing the cleavage furrow of dividing cells. Cytokinesis D is thought to be mediated by chemotaxis, where midwife cells migrate toward dividing cells by sensing an unknown chemoattractant secreted from the cleavage furrow. In this study, to validate this chemotaxis model, we aspirated the fluid from the vicinity of the cleavage furrow of a dividing cell and discharged it onto a neighboring cell using a microcapillary.

Quantitative power Doppler signal assessment in the subchondral bone region of the metacarpophalangeal joint is an effective predictor of radiographic progression in the hand of rheumatoid arthritis: a pilot study.

Ultrasonography is useful for assessment of synovitis in the hand of rheumatoid arthritis (RA) patients. The aim of this study was to investigate the predictive value of the quantitative power Doppler (PD) signal assessment in the subchondral bone region of the metacarpophalangeal (MCP) joint in patients with RA showing radiographic progression of the hand by comparing with those of previously reported scoring systems. Twenty-two patients (20 women) with RA who underwent power Doppler ultrasonography (PDUS) of the bilateral one to five MCP joints at baseline were included in the study.

Phosphorylation-dependent Regnase-1 release from endoplasmic reticulum is critical in IL-17 response.

Regnase-1 (also known as Zc3h12a or MCPIP-1) is an endoribonuclease involved in mRNA degradation of inflammation-associated genes. Regnase-1 is inactivated in response to external stimuli through post-translational modifications including phosphorylation, yet the precise role of phosphorylation remains unknown. Here, we demonstrate that interleukin (IL)-17 induces phosphorylation of Regnase-1 in an Act1-TBK1/IKKi-dependent manner, especially in nonhematopoietic cells.

Quantitative assay of targeted proteome in tomato trichome glandular cells using a large-scale selected reaction monitoring strategy.

Background: Glandular trichomes found in vascular plants are called natural cell factories because they synthesize and store secondary metabolites in glandular cells. To systematically understand the metabolic processes in glandular cells, it is indispensable to analyze cellular proteome dynamics. The conventional proteomics methods based on mass spectrometry have enabled large-scale protein analysis, but require a large number of trichome samples for in-depth analysis and are not suitable for rapid and sensitive quantification of targeted proteins.

Correction of Mass Spectrometric Interferences for Rapid and Precise Isotope Ratio Measurements of Calcium from Biological Samples Using ICP-Mass Spectrometry.

Stable isotope compositions of calcium (Ca) provide useful information concerning metabolic alterations of Ca in human and animal bodies. For the measurements of Ca isotope ratio, great care must be taken for the mass spectrometric interferences on Ca isotopes (Ca, Ca, and Ca) from doubly charged strontium (Sr) ions (Sr, Sr, and Sr). To obtain reliable stable isotope data of Ca, we developed a new correction technique for the mass spectrometric interferences by Sr ions based on standard addition method.

Body Weight Reduction of 5% Improved Blood Pressure and Lipid Profiles in Obese Men and Blood Glucose in Obese Women: A Four-Year Follow-up Observational Study.

Body weight reduction (BWR) of at least 3% in obese Japanese individuals through lifestyle interventions has improved the risk factors for cardiovascular disease (CVD). We aimed to assess the relation between body weight change (BWC) and CVD risk change and to identify lifestyle improvement related to BWR in obese Japanese individuals. Subjects were 2579 health checkup examinees without medicated diabetes, hypertension or dyslipidemia, and a body mass index ≥25 kg/m who completed lifestyle questionnaires in 2008 and 2012.

Bleeding Risk of Warfarin and Direct Oral Anticoagulants in Younger Population: A Historical Cohort Study Using a Japanese Claims Database.

A historical cohort analysis of the Japan medical data center (JMDC) claims databases was performed to compare the incidence rates of bleeding events with warfarin (WF) versus direct oral anticoagulant (DOAC) treatment in patients with non-valvular atrial fibrillation. The aim of this study is to clarify the risk factors for bleeding events in younger patients newly treated with WF or DOAC in clinical practice setting. Patients who newly initiated WF or DOAC treatment from April 2012 to March 2015 were selected from the JMDC claims database.

A GH family 28 endo-polygalacturonase from the brown-rot fungus Fomitopsis palustris: Purification, gene cloning, enzymatic characterization and effects of oxalate.

Brown-rot fungi are the wood-decay basidiomycetes and have ability to break down plant cell wall carbohydrates. It has been suggested that degradation of pectin is important for the initial stages of brown rot. We purified an endo-polygalacturonase (FpPG28A) from the brown-rot fungus Fomitopsis palustris, analysis of the predicted amino acid sequence indicated that FpPG28A belongs to GH family 28.

: To explore the relevance of citrullinated proteins and anti-citrullinated protein antibodies (ACPA) via protein arginine deiminase (PAD) inhibition in peptide glucose-6-phosphate isomerase-induced arthritis (pGIA).: Cl-amidine, a PAD inhibitor, was injected into pGIA. Clinical scores and histopathological findings of ankle joints were assessed.

NEDD4 Is Involved in Inflammation Development during Keloid Formation.

Keloids mark a chronic inflammatory disease characterized by a fibroproliferative disorder of the skin. A genome-wide association study showed that single-nucleotide polymorphism rs8032158 in the neural precursor cell-expressed NEDD4 gene, which has six protein-coding transcript variants (TVs), is genetically linked to keloids. Here, we show that the high frequency of risk allele C in rs8032158 in keloid patients is associated with a selectively higher expression of TV3 of NEDD4 to activate the NF-κB pathway.

Impact of deep ocean mixing on the climatic mean state in the Southern Ocean.

The Southern Ocean is of great importance for the global stratification and biological carbon storage because it is connected to the global ocean conveyor by which atmospheric information absorbed in the Southern Ocean is redistributed globally and buffered over centuries. Therefore, understanding what controls the Southern Ocean climate, the global ocean conveyor, and links between them is a key to quantifying uncertainties in future climate projections. Based on a set of climate model experiments, here we show that the tide-induced micro-scale mixing in the Pacific deep ocean has significant impacts on the wintertime Southern Ocean climate through basin-scale reorganization of ocean stratification and resultant response of the global ocean conveyor.

Bmi1 Regulates IκBα Degradation via Association with the SCF Complex.

Bmi1 is a polycomb group protein and regulator that stabilizes the ubiquitination complex PRC1 in the nucleus with no evidently direct link to the NF-κB pathway. In this study, we report a novel function of Bmi1: its regulation of IκBα ubiquitination in the cytoplasm. A deficiency of Bmi1 inhibited NF-κB-mediated gene expression in vitro and a NF-κB-mediated mouse model of arthritis in vivo.

Presenilin 1 Regulates NF-κB Activation via Association with Breakpoint Cluster Region and Casein Kinase II.

We recently reported that NF-κB-mediated inflammation caused by breakpoint cluster region (BCR) is dependent on the α subunit of casein kinase II (CK2α) complex. In the current study, we demonstrate that presenilin 1 (Psen1), which is a catalytic component of the γ-secretase complex and the mutations of which are known to cause familial Alzheimer disease, acts as a scaffold of the BCR-CK2α-p65 complex to induce NF-κB activation. Indeed, Psen1 deficiency in mouse endothelial cells showed a significant reduction of NF-κB p65 recruitment to target gene promoters.

Eco-friendly synthesis of ionic helical polymers and their chemical properties and reactivity.

Reaction of -(2,4-dinitrophenyl)pyridinium chloride (salt(Cl)) with sodium dicyanamide (Na(CN)N) resulted in anion exchange between Cl and (CN)N to yield a new Zincke salt, salt((CN)N). Reactions of salt((CN)N) with piperazine, specifically ()-(-)- or ()-(+)-2-methylpiperazine under eco-friendly conditions, such as in aqueous solution, in the absence of a catalyst, and at room temperature, resulted in pyridinium ring opening to yield ionic high-molecular-weight polymers with 5-2,4-dienylideneammonium dicyanamide units or chiral 5-(2-methylpiperazinium)-2,4-dienylideneammonium dicyanamide units, namely, polymer(H;(CN)N), polymer(-Me;(CN)N), and polymer(-Me;(CN)N). UV-Vis measurements revealed that the π-conjugation system expanded along the polymer chain due to the orbital interaction between the electrons on the two nitrogen atoms of the piperazinium ring.

Development of a novel immunoproteasome digestion assay for synthetic long peptide vaccine design.

Recently, many autologous tumor antigens have been examined for their potential use in cancer immunotherapy. However, the success of cancer vaccines in clinical trials has been limited, partly because of the limitations of using single, short peptides in most attempts. With this in mind, we aimed to develop multivalent synthetic long peptide (SLP) vaccines containing multiple cytotoxic T-lymphocyte (CTL) epitopes.

Cerebral oximetry for cardiac surgery: a preoperative comparison of device characteristics and pitfalls in interpretation.

Regional cerebral oximetry using near-infrared spectroscopy devices is commonly used for detecting cerebral ischemia during cardiopulmonary bypass, and aim to avoid poor cerebral perfusion which may result in perioperative neurological impairment. Today, several devices that can detect cerebral ischemia are commercially available. Although these devices operate on the same measurement principles, their algorithms for detecting and calculating cerebral ischemia are different and no criteria for directly comparing values measured by such different devices exist.
