Article Synopsis
  • The study aimed to determine whether low-dose rituximab treatment impacts the development of herpes zoster (shingles) in patients who received living kidney transplants.
  • A total of 103 kidney transplant recipients were analyzed, with 50 having received rituximab; the incidence of herpes zoster was compared between those who did and did not receive the treatment.
  • Results showed no significant difference in herpes zoster rates between the two groups, indicating that rituximab therapy does not affect herpes zoster development, while prior vaccination against varicella zoster may help prevent it.

Article Synopsis
  • ERK5 plays a key role in cellular functions like survival and proliferation, and its expression was studied in clear cell renal cell carcinoma (ccRCC) patients to understand its impact on cancer outcomes.
  • Research methods included analyzing ERK5 and miR-143 levels through various techniques, along with pharmacological interventions and animal models to assess ERK5's role in ccRCC.
  • Findings showed that high ERK5 expression was linked to better survival and lower recurrence rates, and inhibiting ERK5 reduced cell growth and enhanced the effectiveness of treatments, suggesting that targeting ERK5 could be beneficial in ccRCC therapy.
