Background: The efficacy of deep brain stimulation (DBS) in treating tremor symptoms in cerebellar disorders remains unclear.
Case Presentation: A 47-year-old woman presented with neck and arm tremor and ataxic speech/gait after four days of >40 °C fever due to septic shock attributed to lithiasis-pyelonephritis. Left ventral intermediate nucleus thalamus DBS alleviated contralateral postural arm tremor, although the action tremor and terminal oscillation remained unchanged.
This study aimed at understanding the background concentration level of tritium in precipitation in southern Japan, where precipitation samples were collected monthly in 2022 in Okinawa and Kagoshima. Tritium concentration in monthly precipitation collected in Okinawa since 2014 ranged from 0.05 to 0.

- The article investigates tritium levels in monthly rainfall in Hiroshima City for 2021, showing fluctuations between 0.16 to 0.78 Bq L-1.
- It also examines stable hydrogen and oxygen isotopes and ionic species to better understand precipitation characteristics and compares these trends with historical data from other areas in Japan.
- The findings indicate that while overall precipitation characteristics are similar to other regions, Hiroshima's tritium levels differ from expected patterns, suggesting potential influences from continental sources.
The functionalization approach for nanomaterials is of great importance for their application in drug delivery systems. Herein, an approach based on block copolymer installation into polymer nanogels was newly developed. Poly(vinyl alcohol)-incorporated polymer nanogels were prepared by a two-step dispersion/precipitation polymerization.

Case Presentation: A Japanese elderly man in his 80s with rheumatoid arthritis on methotrexate was admitted to our hospital complaining persistent pharyngeal pain. Laboratory tests revealed severe pancytopenia, elevated C-reactive protein, and increased creatinine levels.
