Ecological factors associated with fox feces density in an endemic zone in Japan.

Introduction: Human alveolar echinococcosis caused by is an important zoonotic disease in the northern hemisphere. The life cycle of is maintained primarily in wild animals and requires an intermediate host (mainly small mammals). Human can become an intermediate host through accidental ingestion of eggs.

Single-cell profiling of transcriptomic changes during maturation of human oocytes.

Purpose: maturation (IVM) of human oocytes offers an invaluable opportunity for infertility treatment. However, matured oocytes often show lower developmental abilities than their counterparts, and molecular mechanisms underlying successful maturation remain unclear. In this study, we investigated gene expression profiles of matured oocytes at the single-cell level to gain mechanistic insight into IVM of human oocytes.

Effect of the Management Tool for Daily Life Performance on Patients with Cardiovascular Disease: A Randomized Controlled Trial.

Objective: Cardiovascular diseases cause psychological symptoms, such as depression and anxiety. Symptoms of depression have a major effect on patients and worsen prognosis as a result of reduced quality of life and decreased levels of physical activity. Because cardiac rehabilitation (CR) has physical, mental, and secondary preventative effects, it is necessary to evaluate the psychological factors of patients and to provide patients with psychological support based on the results.

A Case of Sjögren's Syndrome Complicated with Interstitial Nephritis and Delayed Onset Autoimmune Hepatitis.

A 61-year-old woman was admitted to our hospital because of muscle paralysis and was found to have severe hypokalemia. A gallium-67 scintigram revealed a positive accumulation in the bilateral salivary glands, and a labial minor salivary gland biopsy demonstrated a massive lymphocyte infiltrate around the salivary ducts. She was diagnosed with Sjögren's syndrome (SS) associated with renal tubular acidosis.

Warfarin use and incidence of stroke in Japanese hemodialysis patients with atrial fibrillation.

Atrial fibrillation (AF) is one of the major risk factor for ischemic stroke, and oral anticoagulation is generally indicated for prevention of stroke. However, the utility of oral anticoagulation for AF in dialysis patients remains controversial. In this single-center, retrospective, observational study, data from 1120 patients on maintenance hemodialysis were analyzed.

IgA nephropathy and psoriatic arthritis that improved with steroid pulse therapy and mizoribine in combination with treatment for chronic tonsillitis and epipharyngitis.

A 65-year-old man was admitted to our hospital with edema and renal dysfunction. He had received a diagnosis of psoriatic arthritis at 50 years of age. As a renal biopsy showed IgA nephropathy (IgAN), bilateral tonsillectomy was performed, and one course of steroid pulse therapy with an oral steroid and mizoribine were subsequently administered.

Glomerular capillary and endothelial cell injury is associated with the formation of necrotizing and crescentic lesions in crescentic glomerulonephritis.

Background: The associations of glomerular capillary and endothelial injury with the formation of necrotizing and crescentic lesions in cases of crescentic glomerulonephritis (GN) have not been evaluated in detail.

Methods: Glomerular capillary and endothelial cell injury were assessed in renal biopsy specimens of crescentic GN, including those from patients with anti-neutrophil cytoplasmic autoantibodies (ANCA) -associated GN (n=45), anti-glomerular basement membrane (GBM) GN (n=7), lupus GN (n=21), and purpura GN (n=45) with light and electron microscopy and immunostaining for CD34.

Results: In ANCA-associated GN, anti-GBM GN, lupus GN, and purpura GN, almost all active necrotizing glomerular lesions began as a loss of individual CD34-positive endothelial cells in glomerular capillaries, with or without leukocyte infiltration.

Acute graft-versus-host disease of the kidney in allogeneic rat bone marrow transplantation.

Allogeneic hematopoietic cell or bone marrow transplantation (BMT) causes graft-versus-host-disease (GVHD). However, the involvement of the kidney in acute GVHD is not well-understood. Acute GVHD was induced in Lewis rats (RT1l) by transplantation of Dark Agouti (DA) rat (RT1(a)) bone marrow cells (6.

A case of secondary focal segmental glomerulosclerosis associated with malignant hypertension.

Focal segmental glomerulosclerosis (FSGS) is associated with various clinicopathological conditions, including hypertension. We report here a case of secondary FSGS associated with malignant hypertension. A 33-year-old man with a 1-month history of visual impairment and headache visited the Department of Ophthalmology at our hospital and was found to have hypertensive retinopathy and severe hypertension (230/160 mmHg).

Renal thrombotic microangiopathy associated with chronic graft-versus-host disease after allogeneic hematopoietic stem cell transplantation.

Thrombotic microangiopathy (TMA) is a major complication after hematopoietic stem cell transplantation (HSCT). In this study, we examined the clinical and pathologic features of 2 patients and 5 autopsy cases with HSCT-associated renal TMA to clarify the association between graft-versus-host disease (GVHD) and renal TMA. The median interval between HSCT and renal biopsy or autopsy was 7 months (range 3-42 months).

[Two cases of rapidly progressive nephritic syndrome complicated with alcoholic liver cirrhosis].

It has been reported that glomerulosclerosis with IgA deposition is likely to be complicated with alcoholic liver cirrhosis. On the other hand, it is said that complications of nephrotic syndrome or rapidly progressive glomerulonephritis (RPGN) are relatively rare. We experienced two patients with alcoholic liver cirrhosis complicated with RPGN syndrome who had obtained favorable outcomes through the use of steroids and immune system suppressors.

Selectivity enhancement for trans-2-(2,3-anthracenedicarboximido)-cyclohexane-derived diastereomers in HPLC by using an ordered organic stationary phase.

2-(2,3-anthracenedicarboximido)cyclohexane derivatives (AC) have been known as the evolutionary diastereomerizing reagents for enantiomer discrimination in HPLC with ODS. However, a substantial separation of diastereomers can be observed only at lower temperatures, such as -40 degrees C. Therefore, in this work, poly(octadecyl acrylate)-grafted silica, ODAn was applied as an alternative stationary phase to ODS for the separation of AC-derived diastereomers.

Enhancement of molecular-shape selectivity in high-performance liquid chromatography through multi-anchoring of comb-shaped polymer on silica.

Poly(octadecylacrylate) having plural trimethoxysilyl groups in the side chain (co-ODA(n)) was newly synthesized and immobilized onto silica through these groups. The liquid chromatographic behavior of silica-supported co-ODA(n) (Sil-co-ODA(n)) was investigated and compared with that of Sil-ODA(n), in which poly(octadecylacrylate) was immobilized through a terminal trimethoxy group at one side of the polymer main chain. Sil-co-ODA(n) showed higher selectivity for molecular shape, especially molecular planarity of PAHs than Sil-ODA(n).

Conformational effect of silica-supported poly(octadecyl acrylate) on molecular-shape selectivity of polycyclic aromatic hydrocarbons in RP-HPLC.

Poly(octadecyl acrylate) with a terminal reactive group was synthesized by radical telomerization in various solvents. The polymers were grafted onto porous silica for use in RP-HPLC, and the molecular recognition ability was investigated along with the selectivity for the structural isomers of polycyclic aromatic hydrocarbons. The mechanism of selectivity was also investigated with differential scanning calorimetry and NMR spectroscopic observations.
