Gait Acquisition with a Quadrilateral Socket after Ultra-short Transfemoral Amputation because of Staphylococcal Toxic Shock Syndrome.

Background: Streptococcal toxic shock syndrome (STSS) is a notifiable disease under Japan's Infectious Disease Control Law and has become a pandemic following COVID-19. STSS often leads to necrotizing fasciitis, with a mortality rate exceeding 30%. Even in surviving patients, limb amputations are common.

Neutrophil extracellular traps (NETs), transfusion requirements and clinical outcomes in orthotopic liver transplantation.

Inflammatory phenomena have a direct impact on the prognosis of orthotopic liver transplantation (OLT). Neutrophil extracellular traps (NETs) contribute to OLT inflammation and hemostasis imbalance in OLT. The association between NETosis, clinical outcomes and transfusion requirements is not determined.

Recombinant lectin Gg for brain imaging of glycan structure and formation in the CNS node of Ranvier.

The nodes of Ranvier are unmyelinated gaps in the axon, important for the efficient transmission of action potentials. Despite the identification of several glycoproteins involved in node formation and maintenance, glycans' structure and formation in the node remain unclear. Previously, we developed a recombinant lectin from the Clostridium botulinum neurotoxin complex, specific to the galactose and N-acetylgalactosamine terminal epitopes (Gg).

Molecular Characteristics and Antimicrobial Resistance of Serovar Schwarzengrund from Chicken Meat in Japan.

Our previous study revealed that serovar Schwarzengrund-contaminated areas of broiler chickens have expanded from West Japan to East Japan. The present study investigated the antimicrobial resistance and molecular characteristics of 124 Schwarzengrund isolates obtained from chicken meat produced in East and West Japan from 2008 to 2019.

Salmonella was isolated from 143 samples (59.

Formation of α-synuclein aggregates in aqueous ethylammonium nitrate solutions.

The effect of adding ethylammonium nitrate (EAN), which is an ionic liquid (IL), on the aggregate formation of α-synuclein (α-Syn) in aqueous solution has been investigated. FTIR and Raman spectroscopy were used to investigate changes in the secondary structure of α-Syn and in the states of water molecules and EAN. The results presented here show that the addition of EAN to α-Syn causes the formation of an intermolecular β-sheet structure in the following manner: native disordered state → polyproline II (PPII)-helix → intermolecular β-sheet (α-Syn amyloid-like aggregates: α-SynA).

Risk Factors for Transfusion after Orthotopic Liver Transplantation.

Background: Transfusion of blood products during orthotopic liver transplantation (OLT) is associated with increased morbidity and mortality. Although risk factors associated with intraoperative transfusion requirements have been widely assessed, published data on the prediction of postoperative transfusion requirements are sparse.

Objectives: The aim of this study was to evaluate risk factors for postoperative allogeneic transfusion requirements in OLT.

Compatibility Evaluation of Non-Woven Sheet Composite of Silk Fibroin and Polyurethane in the Wet State.

SF/polyurethane composite non-woven sheet was fabricated to evaluate the cardiovascular tissue engineering materials in the wet state. The compatibility and microstructure analyses were carried out on the fabricated SF/polyurethane composite non-woven sheet by thermal analysis and solid-state NMR analysis in the wet state. To evaluate the modulus of elasticity, a tensile test was performed and supported with dynamic viscoelasticity and mechanical analysis.

Structural connectivity in spatial attention network: reconstruction from left hemispatial neglect.

Left hemispatial neglect (neglect) is an impaired state of spatial attention. We aimed to reconstruct structural connectivity in the spatial attention network and to identify disconnection patterns underlying neglect. We enrolled 59 right-handed patients who had their first-ever infarction in the right hemisphere and classified them into neglect group (34 patients with neglect) and control group (25 patients without neglect).

Right hand predominant constructional apraxia due to right hemisphere infarction without corpus callosum lesions.

A 74-year-old right-handed woman without cognitive impairment suddenly developed nonfluent aphasia. Brain MRI showed acute infarction in the right frontal lobe and insula without involvement of the corpus callosum. A neurological examination demonstrated not only transcortical motor aphasia, but also ideomotor apraxia and right hand predominant constructional apraxia (CA).

The GSTP1 gene is a susceptibility gene for childhood asthma and the GSTM1 gene is a modifier of the GSTP1 gene.

Background: Bronchial asthma is a chronic airway disorder characterized by bronchial inflammation. Oxidative stress is a key component of inflammation. Glutathione S-transferase P1 (GSTP1), the abundant isoform of glutathione S-transferases (GSTs) in lung epithelium, plays a key role in cellular protection against oxidative stress.

Monocyte chemoattractant protein 1 mediates retinal detachment-induced photoreceptor apoptosis.

Photoreceptor apoptosis is a major cause of visual loss in retinal detachment (RD) and several other visual disorders, but the underlying mechanisms remain elusive. Recently, increased expression of monocyte chemoattractant protein 1 (MCP-1) was reported in vitreous humor samples of patients with RD and diabetic retinopathy as well as in the brain tissues of patients with neurodegenerative diseases, including Alzheimer's disease and multiple sclerosis. Here we report that MCP-1 plays a critical role in mediating photoreceptor apoptosis in an experimental model of RD.

Tumor necrosis factor-alpha mediates oligodendrocyte death and delayed retinal ganglion cell loss in a mouse model of glaucoma.

Glaucoma is a widespread ocular disease characterized by a progressive loss of retinal ganglion cells (RGCs). Previous studies suggest that the cytokine tumor necrosis factor-alpha (TNF-alpha) may contribute to the disease process, although its role in vivo and its mechanism of action are unclear. To investigate pathophysiological mechanisms in glaucoma, we induced ocular hypertension (OH) in mice by angle closure via laser irradiation.

Effects of Ibuprofen and High-Voltage Electric Stimulation on Acute Edema Formation After Blunt Trauma to Limbs of Rats.

Context: Ibuprofen is widely used to manage pain and inflammation after orthopaedic trauma, but its effect on acute swelling has not been investigated. Cathodal high-voltage pulsed current (CHVPC) at 120 pulses per second and 90% of visible motor threshold is known to curb edema formation after blunt trauma to the hind limbs of rats.Objective: To examine the effects of ibuprofen, continuous CHVPC, and simultaneous ibuprofen and CHVPC on acute edema formation after blunt trauma to the hind limbs of rats.

Linkage and association of childhood asthma with the chromosome 12 genes.

Several studies have shown linkage of chromosome region 12q13-24 to bronchial asthma and related phenotypes in ethnically diverse populations. In the Japanese population, a genome-wide study failed to show strong evidence of linkage of this region. Chromosome 12 genes that showed association with the disease in at least one report include: the signal transducer and activator of transcription 6 gene ( STAT6), the nitrogen oxide synthetase 1 gene ( NOS1), the interferon gamma gene ( IFNG), and the activation-induced cytidine deaminase gene ( AICDA).

[Erythropoietin Receptor-Mediated Proliferative Signal Transduction in Leukemic Cell Line KOCL-33].

In order to investigate the expression of erythropoietin receptor(EPOR) in leukemic cell line and clarify the mechanism of proliferative signal transduction mediated by EPOR in the leukemic cell line KOCL-33, biotinylated EPO and flow cytometry were used for detection of EPOR expression, (3)H-TdR incoporation for cell proliferation, immunoprecipitation and Western blot analysis were used to investigate the tyrosine phosphorylation of signal transduction proteins as the causation of enhanced proliferation of KOCL-33 cells.
