Background: Sex differences significantly affect many laboratory test results. However, sex differences in the serum and urine levels of the major vascular endothelial growth factor-A (VEGF-A) isoforms, VEGF-A and VEGF-A, remain unclear. This study aimed to assess these sex-based profiles using a newly developed assay system.

Many biobanks store biological samples and use them for various analyses, including proteomics. Therefore, it is necessary to consider the denaturation of target proteins during long-term storage. We analyzed 16-year-old cryopreserved serum samples using the SomaScan platform, a novel proteomic assay, to determine whether adiponectin and resistin concentrations were consistent with those measured in our previous studies using a different platform.

The number of individuals with age-related mild cognitive impairment and subsequent dementia has inevitably increased with the rise in population aging. It is important to maintain cognitive function or decelerate declines in cognitive function. However, the evidence on lifestyle-based factors associated with this decline is lacking.

With the increase in life expectancy in Japan, the proportion of older adults requiring medical assistance continues to increase. Hence, the Japanese government proposed the establishment of a community-based integrated care system, aimed at ensuring housing, medical care, long-term care, prevention, and lifestyle support in a comprehensive manner by 2025. To achieve this paradigm shift, pharmacies must collaborate with their respective medical providers.

A T217M heterozygous mutation in the SLC22A12 gene caused renal hypouricemia; this patient with IgA nephropathy had no findings other than IgA nephropathy on renal biopsy. Hypouricemia was susceptible to oxidative stress, but IgA nephropathy in the patient with hypouricemia could be treated with steroid pulse therapy without adverse events.

Article Synopsis
  • Gout is caused by the buildup of monosodium urate due to high uric acid levels (hyperuricemia), but most people with high uric acid levels don’t show symptoms.
  • A study involving genetic and metabolomic analysis was conducted with 33 gout patients and 9 asymptomatic individuals to identify potential biomarkers distinguishing the two groups; however, certain genetic markers did not show significant differences.
  • The study found that levels of specific metabolites, particularly urinary nicotinate and citrate cycle intermediates, differed significantly between gout patients and those with asymptomatic hyperuricemia, suggesting other factors may also influence the development of gout.

  • Indonesian care staff in Japan are increasing, but there's no assessment tool in their language to evaluate their dementia care practices.
  • This study translated the Person-centered Care Assessment Tool (P-CAT) into Indonesian and tested its reliability and validity with 218 care staff members through various analyses.
  • The findings suggest that the Indonesian P-CAT is a valid and reliable measure for assessing person-centered care among these staff, with promising implications for improving care practices.

Multidimensional assessments are important in evaluating the overall health of older adults. The comprehensive geriatric assessment (CGA) is a representative framework; however, the burden associated with the CGA has led to the development of simplified multidimensional tools. Comparing these tools to the CGA can help utilize them effectively.

Two-thirds of urate is excreted via the renal pathway and the remaining one-third via the extra-renal pathway, the latter mainly via the intestine in healthy individuals. ABCG2, a urate exporter, is expressed in various tissues including the kidney and intestine, and its dysfunction leads to hyperuricemia and gout. ABCG2 is regarded as being responsible for most of the extra-renal urate excretion.

Tannins (TAs) are an anti-nutritional substance commonly used as a natural feed additive for livestock. However, our previous study described the dose-dependent adverse effects of TA on immune responses and growth in chickens. In this study, we evaluated the protective effects of a probiotic preparation (BT) consisting of three different bacteria ( and ) against TA-induced immunosuppression in chickens.

Renal hypouricemia is a disease caused by the dysfunction of renal urate transporters. This disease is known to cause exercise-induced acute kidney injury, but its mechanism has not yet been established. To analyze the mechanism by which hypouricemia causes renal failure, we conducted a semi-ischemic forearm exercise stress test to mimic exercise conditions in five healthy subjects, six patients with renal hypouricemia, and one patient with xanthinuria and analyzed the changes in purine metabolites.

Article Synopsis
  • The study investigates the potential link between asymptomatic hyperuricemia (high uric acid levels without symptoms) and kidney function decline, particularly focusing on the role of the ABCG2 transporter, which is responsible for urate excretion.
  • Conducted among 1,885 Japanese adults with normal kidney function, the research finds that asymptomatic hyperuricemia is generally not associated with a decline in kidney function, except for those with lower ABCG2 function categories, where a significant association was observed.
  • The results suggest that individuals with high uric acid levels and less effective ABCG2 function experience a faster decline in kidney function, highlighting the importance of monitoring uric acid

The thymus is a primary lymphoid organ where the primary T cell repertoire is generated. Thymus atrophy is induced by various conditions, including infectious diseases, glucocorticoid treatment, and poor breeding management. Cattle with thymus atrophy tend to exhibit weak calf syndrome, a condition in which approximately half of neonates die shortly after birth.

Hypouricemia in kidney transplant (KT) recipients is rare since they usually have subnormal kidney function which raises serum uric acid level. Recently, interests in pathogenesis of hypouricemia have been increasing due to the understanding of the role of uric acid transporter in renal hypouricemia (RHUC). We herein report the case of RHUC consequently developed in a KT recipient from a living donor with RHUC diagnosed by the detailed urinary and genetic test.

Flowering is the developmental transition from the vegetative to the reproductive phase. FLOWERING LOCUS T (FT), SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1), and LEAFY (LFY) are floral integrators. These genes are repressed by several floral repressors including EARLY FLOWERING3 (ELF3), SHORT VEGETATIVE PHASE (SVP), TEMPRANILLO1 (TEM1), and TEM2.

Background: Homecare nurses play an important role in end-of-life care. A protocol is needed for the remote verification of expected deaths using information and communication technologies (ICT), that is consistent with Japanese guidelines.

Aim: To clarify the processes that nurses use to verify deaths and to develop a tentative nursing protocol for verifying expected deaths, using home-based ICT.

Single cell arrays provide an accurate classification of analyte cells through an image-based analysis of cellular phenotypes. Light-guided cell retrieval from a single cell array is a promising approach for the rapid and simple sorting of difficult to distinguish cells. In this study, we developed a single cell array enclosed with a photodegradable hydrogel in microwells to enable both comprehensive image-based single cell analysis and light-guided cell retrieval.

Dysfunctional variants of ATP-binding cassette transporter subfamily G member 2 (ABCG2), a urate transporter in the kidney and intestine, are the major causes of hyperuricemia and gout. A recent study found that ABCG2 is a major transporter of uremic toxins; however, few studies have investigated the relationship between ABCG2 gene polymorphisms and mortality. This prospective cohort study of 1214 hemodialysis patients investigated the association between serum uric acid levels and ABCG2 genotype and mortality.
