Adverse reactions and effects on renal function of COVID-19 vaccines in patients with IgA nephropathy.

Background: Although vaccination has been reported to reduce the morbidity and severity of COVID-19 infection in patients with kidney disease, gross hematuria is frequently reported following vaccination in patients with IgA nephropathy. We investigated the frequency of gross hematuria following COVID-19 vaccination and its effect on renal function in IgA nephropathy patients.

Methods: Adverse reactions after two or more COVID-19 vaccine doses were investigated in 295 IgA nephropathy patients attending Osaka Cty general hospital from September 2021 to November 2022.

Genomic analysis of the appearance of ovarian mast cells in neonatal MRL/MpJ mice.

In MRL/MpJ mice, ovarian mast cells (OMCs) are more abundant than in other mouse strains, and tend to distribute beneath the ovarian surface epithelium at birth. This study investigated the factors regulating the appearance of neonatal OMCs in progeny of the cross between MRL/MpJ and C57BL/6N strains. F1 neonates had less than half the number of OMCs than MRL/MpJ.

Relationship between numerous mast cells and early follicular development in neonatal MRL/MpJ mouse ovaries.

In the neonatal mouse ovary, clusters of oocytes called nests break into smaller cysts and subsequently form individual follicles. During this period, we found numerous mast cells in the ovary of MRL/MpJ mice and investigated their appearance and morphology with follicular development. The ovarian mast cells, which were already present at postnatal day 0, tended to localize adjacent to the surface epithelium.

[Anesthetic management of a patient with transfusion-related acute lung injury (TRALI)].

Transfusion-related acute lung injury (TRALI) is characterized by pulmonary edema and hypoxemia within 6 hours of transfusion in the absence of other causes of acute lung injury or circulatory overload and is now considered the leading cause of transfusion-related death. We report a female patient who showed hypoxemia after transfusion without any other causes of acute lung injury. The patient is a 43-year-old woman, who received emergency transurethral hemostasis for bladder hemorrhage with hematuria and low hemoglobin concentration (3.

Synthesis and glycosidase inhibitory activity of some N-substituted 5a-carba-beta-fuco- and beta-galactopyranosylamines, and selected derivatives.

In the course of chemical modification of alpha-fucosidase inhibitors of 5a-carba-fucopyranosylamine type, an N-dodecyl derivative of the enantiomer 6-deoxy-5a-carba-beta-D-galactopyranosylamine demonstrated very strong inhibition of beta-galactosidase and beta-glucosidase. This finding led us to synthesize corresponding 6-hydroxy compounds, in order to elucidate structure-activity relationships for inhibitors of this type. Among four N-alkyl-5a-carba-beta-D-galactopyranosylamines prepared, the N-octyl derivative could be demonstrated to possess moderate activity toward alpha- and beta-galactosidases, and beta-glucosidase.

[The effect of radiotherapy on patients with prostate specific antigen failure after radical prostatectomy].

We studied the effect of radiotherapy on patients with re-elevation of prostate specific antigen (PSA) after radical prostatectomy. Radiotherapy was performed on 8 patients with re-elevated PSA after radical prostatectomy without any previous treatment. Pathological stages were B in 2 patients, and C in 6 patients.

Renal lymphoma associated with Castleman's disease.

We report the second case in the literature of a renal lymphoma associated with multicentric Castleman's disease.

Convenient synthesis and evaluation of glycosidase inhibitory activity of alpha- and beta-galactose-type valienamines, and some N-alkyl derivatives.

Valienamine analogues having alpha- and beta-galactose-type structures were synthesized by racemic modification from (1SR,2RS,3SR)-6-methylenecyclohex-4-ene-1,2,3-triol. Four N-alkyl derivatives of the beta-anomer were readily prepared selectively by treatment of key intermediate 2,6-di-O-acetyl-3,4-O-isopropylidene-5a-carba-alpha- and beta-l-arabino-hex-5(5a)-enopyranosyl bromides with alkyl amines. All compounds were assayed for inhibitory activity against six glycosidases, and the N-dodecyl derivative was shown to be a very strong inhibitor of beta-galactosidase (IC(50) 0.

Coexistence of renal replacement lipomatosis with xanthogranulomatous pyelonephritis.

We report on a case of coexistence of replacement lipomatosis with xanthogranulomatous pyelonephritis (XGP) in the same kidney associated with staghorn calculi. A 63-year-old man was admitted to hospital complaining of a right abdominal mass. Computed tomography (CT) showed renal parenchymal atrophy with extremely increased perirenal fat.

Chemical chaperone therapy for brain pathology in G(M1)-gangliosidosis.

We synthesized a galactose derivative, N-octyl-4-epi-beta-valienamine (NOEV), for a molecular therapy (chemical chaperone therapy) of a human neurogenetic disease, beta-galactosidosis (GM1-gangliosidosis and Morquio B disease). It is a potent inhibitor of lysosomal beta-galactosidase in vitro. Addition of NOEV in the culture medium restored mutant enzyme activity in cultured human or murine fibroblasts at low intracellular concentrations, resulting in a marked decrease of intracellular substrate storage.

[Laparoscopic cholecystectomy under general anesthesia for a woman in the 28th week of gestation].

Anesthesia for laparoscopic cholecystectomy under hypobaric pneumoperitoneum was given to a pregnant woman in 28th week of gestation. Anesthesia was induced by administering thiopental(5 mg.kg-1) and vecuronium (0.

[Treatment results of radical prostatectomy in clinical stage B and C prostate cancer: comparison of the neoadjuvant therapy group versus the surgery group; retrospective analysis of 80 cases].

Between 1994 and 2001, 80 patients underwent radical prostatectomy without adjuvant therapy for clinical stage B and C prostate cancer. The patients were not treated with adjuvant therapy before biochemical prostate specific antigen (PSA) failure. Of all 80 patients, 35 patients (43.

Synthesis and glycosidase inhibitory activity of some N-substituted 6-deoxy-5a-carba-beta-DL- and L-galactopyranosylamines.

Chemical modification of 5a-carba-beta-DL-fucopyranosylamine (3) generated six N-substituted derivatives 9a-f, among which N-octyl 9b, decyl 9c, and phenylbutyl ones 9f were found to be very strong beta-galactosidase as well as beta-glucosidase inhibitors. The inhibitory activity appeared attributable to D-enantiomers from biological assays of prepared L-enantiomers. Therefore, 6-deoxy-5a-carba-beta-D-galactopyranosylamine (D-3) might be a promising lead compound for further design of new carba sugar-type beta-galactosidase inhibitors.

[Successful treatment for renal cell carcinoma with lung metastases by interleukin-2 and interferon-alfa: a case report].

We report a case in which a regimen of interleukin-2 (IL-2) and interferon alfa (IFN-alpha) was effective against renal cell carcinoma with lung metastases. A 69-year-old man diagnosed with right renal tumor had not received treatment for 28 months. He was admitted to our hospital for treatment.

Pheochromocytoma of the urinary bladder without typical symptoms.

Pheochromocytoma of the urinary bladder is an unusual tumor that typically presents with hypertensive crises related to micturition. We report, herein, the case of a 62-year-old woman with bladder pheochromocytoma. The patient presented with a bladder tumor that was incidentally found by computed tomography (CT) without the triad of sustained hypertension, hematuria and postmicturitional syncope.

Convenient synthesis and evaluation of enzyme inhibitory activity of several N-alkyl-, N-phenylalkyl, and cyclic isourea derivatives of 5a-carba-alpha-DL-fucopyranosylamine.

Convenient synthesis and chemical modification of the potent alpha-L-fucosidase inhibitor, 5a-carba-alpha-DL-fucopyranosylamine (1), are described. Among seven N-substituted and three cyclic isourea derivatives newly prepared, the N-octyl derivative was found to be the strongest inhibitor of alpha-L-fucosidase (bovine kidney) more potent (K(i)=0.016 microM) than deoxyfuconojirimycin (K(i)=0.
