Article Synopsis
  • Equol, a compound similar to estrogen produced by gut bacteria from soybean isoflavones, may have beneficial effects on metabolism, but its relationship to type 2 diabetes is not well understood.* -
  • A study with 147 type 2 diabetes patients and 147 matched controls revealed that those with diabetes had lower urinary equol levels and a lower proportion of equol producers compared to non-diabetic participants.* -
  • In women, the proportion of equol producers was significantly lower in those with diabetes, and female equol producers showed a lower incidence of dyslipidemia compared to non-producers; no significant differences were noted in men.*

Objectives: We aimed to validate a newly developed antigen-detecting rapid diagnostic test (Ag-RDT) for SARS-CoV-2 using anterior nasal specimens.

Methods: Between February 12 and September 30, 2021, 16 patients (age range, <1 month-76 years) were enrolled, and samples were collected simultaneously from anterior nasal and nasopharyngeal sites continuously during hospitalization. The primary end points were the diagnostic accuracy of the Ag-RDT and utility of anterior nasal specimens.

Bone growth is most remarkable during puberty. This study aimed to clarify the effects of physique and physical strength on bone mineral density and bone metabolism markers during puberty to help improve bone growth during puberty and prevent future osteoporosis. There were 277 pubertal participants (125 boys and 152 girls) in this survey from 2009 to 2015, all aged 10/11 and 14/15 years.

Telomere (TL) is a biomarker of biological aging, and its shortening is associated with major risk factors for cardiovascular diseases (CVD). This study aimed to identify whether TL is associated with arterial stiffness as reflected by brachial-ankle pulse wave velocity (baPWV). This population-based cross-sectional study involved 1065 individuals in the Iwaki area, Japan.

Introduction: Digital immunoassays are generally regarded as superior tests for the detection of infectious disease pathogens, but there have been insufficient data concerning SARS-CoV-2 immunoassays.

Methods: We prospectively evaluated a novel digital immunoassay (RapidTesta SARS-CoV-2). Two nasopharyngeal samples were simultaneously collected for antigen tests and Real-time RT-PCR.

It is known that clinic blood pressure (BP), gender, cigarette smoking, dyslipidemia, anemia and thiazolidenediones (TZD) treatment are predictors for clinically significant diabetic macula edema (CSDME). We examined a most risky factor for CSDME in Japanese patients with type 2 diabetes mellitus (T2DM) and diabetic retinopathy (DR) confirmed using optical coherence tomography by multiple regression analysis (MRA). As the risk factors, wakening-up BP was added to such factors.

The exact role of cyclooxygenase-2 (COX-2) in neurodegeneration of retinal ganglion cells (RGCs) in vivo following ischemia-reperfusion injury of the retina was unknown. We made transgenic mice in which the Thy-1.2 promoter drives the expression of EGFP cDNA (Thy-1-EGFP) in RGCs to monitor RGC survival and death in retinal whole mount preparations and in live animals.
