Anthocyanins as potent inhibitors of pentosidine synthesis: Antioxidant-mediated effects.

Pentosidine (PEN), an advanced glycation end product (AGE), is associated with various age-related diseases and schizophrenia. This study aimed to identify the natural compounds that inhibit PEN synthesis from glucuronic acid using an in vitro system. A screening of 93 natural compounds revealed 47 that reduced PEN synthesis by > 50 %, with eight inhibiting it by > 80 %.

Human iPSC-derived renal collecting duct organoid model cystogenesis in ADPKD.

In autosomal dominant polycystic kidney disease (ADPKD), renal cyst lesions predominantly arise from collecting ducts (CDs). However, relevant CD cyst models using human cells are lacking. Although previous reports have generated in vitro renal tubule cyst models from human induced pluripotent stem cells (hiPSCs), therapeutic drug candidates for ADPKD have not been identified.

Effectiveness of weight-loss prevention with continual nutrition counseling in postoperative outpatients with stage IA and IB gastric cancer.

Outpatient nutritional counseling by a registered dietitian is often performed to prevent weight loss, but evidence supporting this practice is insufficient. In this study, we aimed to clarify the effectiveness of four-time outpatient nutritional counseling in weight-loss prevention compared with conventional intervention limited to one-time nutritional counseling. This study was designed as a retrospective cohort study.

High masticatory ability attenuates psychosocial stress: A cross-sectional study.

Mastication interventions have previously been shown to alleviate acute stress. However, the relationship between masticatory performance and stress response among individuals remains unclear. This study aimed to examine the relationship between masticatory ability and stress response in young women by measuring the autonomic nerve function and salivary α-amylase activity during psychosocial stress.

Characteristics of patients who developed glucose intolerance in the early period after partial pancreatectomy.

Background: New-onset diabetes mellitus (DM) often develops after partial pancreatectomy. Little is known regarding how soon patients develop glucose intolerance after partial pancreatectomy. We investigated the incidence of and factors contributing to the development of glucose intolerance during hospitalization after partial pancreatectomy.

Expansion of Human iPSC-Derived Ureteric Bud Organoids with Repeated Branching Potential.

Ureteric bud (UB) is the embryonic kidney progenitor tissue that gives rise to the collecting duct and lower urinary tract. UB-like structures generated from human pluripotent stem cells by previously reported methods show limited developmental ability and limited branching. Here we report a method to generate UB organoids that possess epithelial polarity and tubular lumen and repeat branching morphogenesis.

Masked type 1 diabetes mellitus (T1DM) unveiled by glucocorticoid replacement: a case of simultaneous development of T1DM and hypophysitis in an elderly woman.

As a rare condition characterized by inflammation of the pituitary gland, hypophysitis usually results in hypopituitarism and pituitary enlargement. The most critical outcome of hypopituitarism is caused by secondary adrenal insufficiency. Glucocorticoid deficiency is a life-threatening condition, and patients who develop this deficiency require prompt diagnosis and treatment.

VISCERAL AND SUBCUTANEOUS FAT INCREASED AFTER TREATMENT OF GRAVES DISEASE.

Patients with Graves disease (GD) tend to gain weight after treatment, but it remains unknown if weight gain is associated with an increase in the visceral and/or subcutaneous fat areas (VFA, SFA). We enrolled 25 newly diagnosed GD patients (22 females, median age 33.0 years) and studied their clinical parameters, and VFA and SFA measured by a dual bioelectric impedance analysis.

HYPOTHYROIDISM COULD BE A POTENTIAL FACTOR TO PROLONG SUBCUTANEOUS NODULES OF EXENATIDE ONCE WEEKLY: A CASE REPORT.

Objective: Exenatide once weekly (ExeOW) is one of the long-acting glucagon-like peptide 1 receptor agonists. Embedding exenatide in poly(D,L-lactide-co-glycolide) microspheres enables the once-weekly subcutaneous injection of exenatide as a treatment for diabetes. We report a case of a patient with type 2 diabetes and hypothyroidism who developed long-standing subcutaneous nodules after treatment by ExeOW injection.

RENAL FUNCTION AND PLASMA RENIN ACTIVITY AS POTENTIAL FACTORS CAUSING HYPERKALEMIA IN PATIENTS WITH THYROID CARCINOMA UNDERGOING THYROID HORMONE WITHDRAWAL FOR RADIOACTIVE IODINE THERAPY.

Hypothyroidism is not commonly considered a cause of hyperkalemia. We previously reported that hyperkalemia was observed mainly in elderly patients treated with renin-angiotensin-aldosterone system (RAS) inhibitors when levothyroxine treatment was withdrawn for the thyroidectomized patients with thyroid carcinoma to undergo radioactive iodine treatment. Here, we investigated whether acute hypothyroidism causes hyperkalemia in patients who were not treated with RAS inhibitors.

Impaired early-phase suppression of glucagon secretion after glucose load is associated with insulin requirement during pregnancy in gestational diabetes.

Aims/introduction: The role of glucagon abnormality has recently been reported in type 2 diabetes; however, its role in gestational diabetes mellitus (GDM) is still unknown. The glucose intolerance in GDM is heterogeneous, and not all patients require insulin treatment during pregnancy. Here, we investigated whether glucagon abnormality is associated with the requirement for insulin treatment during pregnancy.

Predictive factors of efficacy of combination therapy with basal insulin and liraglutide in type 2 diabetes when switched from longstanding basal-bolus insulin: Association between the responses of β- and α-cells to GLP-1 stimulation and the glycaemic control at 6 months after switching therapy.

Aims: To evaluate the glycaemic control of combination therapy with basal insulin and liraglutide, and to explore the factors predictive of efficacy in patients with type 2 diabetes when switched from longstanding basal-bolus insulin therapy.

Methods: We studied 41 patients who switched from basal-bolus insulin therapy of more than 3 years to basal insulin/liraglutide combination therapy. Glycaemic control was evaluated at 6 months after switching therapy and used to subdivide the patients into good-responders (HbA1c <7.

Sex differences in insulin and glucagon responses for glucose homeostasis in young healthy Japanese adults.

It has been reported that glucose responses during the oral glucose tolerance test differ between healthy women and men. However, it remains unknown what factors contribute to these differences between the sexes. The present study analyzed the insulin and glucagon responses during the oral glucose tolerance test in 25 female and 38 male healthy young adults aged 22-30 years.

Relation between change in treatment for central diabetes insipidus and body weight loss.

Background: Patients with central diabetes insipidus (CDI) are known to lose weight because their polydipsia interferes with their nutritional intake. We retrospectively examined weight changes in CDI patients when they switched from nasal to oral desmopressin.

Methods: Twenty-three patients with CDI were included.

Dynamic visual responses of accommodation and vergence to electro-holographic images.

Electro-holography can display images without inducing fatigue and three-dimensional (3D) sickness, i.e., visual discomfort due to viewing a stereoscopic display.

Interaction properties of human TRAMP-like proteins and their role in pre-rRNA 5'ETS turnover.

In yeast, the Trf4/5-Air1/2-Mtr4 polyadenylation (TRAMP) complex acts as a cofactor for the nuclear exosome to promote degradation of various RNAs. However, the corresponding machinery in mammals is less characterized. We analyzed the interactions of the human TRAMP-like proteins, PAPD5, ZCCHC7, and MTR4, with the nuclear exosome.

Quality of life in the patients with central diabetes insipidus assessed by Nagasaki Diabetes Insipidus Questionnaire.

Central diabetes insipidus (CDI) is characterized by polyuria and polydipsia due to a deficiency of vasopressin. Currently, the treatment goal for CDI is improvement of quality of life (QOL) by desmopressin (DDAVP) without developing hyponatremia. However, there is no reliable measure for QOL in CDI patients.

Deoxycorticosterone-producing adenoma concomitant with aldosterone-producing microadenoma: a challenging combination.

Objective: To describe the challenging case of a 59-year-old male with a deoxycorticosterone (DOC)-producing adrenal adenoma concomitant with an aldosterone-producing microadenoma.

Methods: We measured the patient's aldosterone and progesterone levels during adrenal venous sampling (AVS). The steroidogenic enzyme expression was studied with in situ hybridization (ISH).
