Idiopathic infantile hypercalcemia (IIH) is characterized by hypercalcemia, nephrocalcinosis, vomiting, dehydration, and failure to thrive. It is caused by the presence of biallelic loss-of-function variants in the locus. Although hypercalcemia has been linked to the consumption of vitamin D-fortified milk, no reports have documented its role in triggering IIH in patients with variants.

Metabolic dysfunction-associated steatohepatitis (MASH, previously termed non-alcoholic steatohepatitis (NASH)), is a major complication of obesity that promotes fatty liver disease. MASH is characterized by progressive tissue fibrosis and sterile liver inflammation that can lead to liver cirrhosis, cancer, and death. The molecular mechanisms of fibrosis in MASH and its systemic control remain poorly understood.

Background: Because patients often already have coronary artery disease (CAD) at the time of a coronary artery computed tomography angiography (CCTA) examination, we examined the medications prescribed by medical doctors for lifestyle-related diseases and investigated what possible role pharmacists can play in prescribing.

Methods: Patients (n = 1357) who underwent CCTA examination were divided into two groups according to the presence or absence of lifestyle-related diseases [hypertension (HTN), dyslipidemia (DL) and diabetes mellitus (DM)], and the relationship between the presence or absence of CAD was examined.

Results: The rate of CAD was significantly higher in patients with HTN, DL or DM than in patients without these diseases.

Sarcopenia is prevalent among 11-25% of adult cancer survivors, depending on the cancer type, although the available data on post-treatment survivors in Japan are limited. If cancer patients develop cachexia, they may experience sustained weight loss as a result, ultimately leading to sarcopenia. Conversely, some patients experience post-treatment weight gain, resulting in sarcopenic obesity.

  • - Early weaning (EW) in mice leads to increased anxiety and stress responses in adulthood, affecting both behavior and immune function.
  • - Mice subjected to EW showed significant differences in behavior tests compared to normally weaned (NW) mice, along with notable changes in their gut microbiome composition, specifically reduced Erysipelotrichaceae.
  • - Germ-free mice colonized with gut microbiota from EW mice exhibited higher depressive behaviors and altered immune cell profiles, indicating that changes in gut microbiota due to EW can influence mood and immunity.

The chytrid fungus Batrachochytrium salamandrivorans [Bsal] is causing declines in the amphibian populations. After a decade of mapping the pathogen in Europe, where it is causing dramatic outbreaks, and North America, where its arrival would affect to the salamander's biodiversity hotspot, little is known about its current status in Asia, from presumably is native. Japan has several species considered as potential carriers, but no regulation is implemented against Bsal spreading.

Titanium (Ti) is an attractive material, abundant in nature and possessing superior mechanical and chemical properties. However, its widespread use is significantly hampered by the strong affinity between titanium and oxygen (O), resulting in elevated manufacturing costs during the refining, melting, and casting processes. The current work introduces a high-throughput technique that effectively reduces the oxygen content in molten titanium to a level suitable for structural material applications (1000 mass ppm, equivalent to 0.

Article Synopsis
  • Genomic anomalies pose significant challenges for the safe use of induced pluripotent stem cells (iPSCs), and their origins and developmental processes are not fully understood.
  • Whole genome sequencing (WGS) analysis reveals that the mutations in iPSCs are mainly new occurrences and highlights that regions like CpG sequences and retrotransposons, especially the AluY subfamily, are particularly mutation-prone.
  • The study suggests that both the deamination of cytosine and the demethylation of methylated cytosine contribute to mutations during iPSC creation, indicating that these factors influence genome reprogramming.
