In organisms ranging from vertebrates to plants, major components of centromeres are rapidly evolving repeat sequences, such as tandem repeats (TRs) and transposable elements (TEs), which harbour centromere-specific histone H3 (CENH3). Complete centromere structures recently determined in human and Arabidopsis suggest frequent integration and purging of retrotransposons within the TR regions of centromeres. Despite the high impact of 'centrophilic' retrotransposons on the paradox of rapid centromere evolution, the mechanisms involved in centromere targeting remain poorly understood in any organism.

Article Synopsis
  • - The study examined the outcomes of laparoscopic retroperitoneal lymph node dissection (RPLND) in post-chemotherapy patients with nonseminomatous testicular germ-cell tumors at Kyushu University Hospital between 2016 and 2024.
  • - A total of 13 patients participated, with median tumor sizes of 11 mm, and the procedure showed low median blood loss (27 mL) and no severe complications.
  • - The results indicate that laparoscopic RPLND is a safe and effective minimally invasive option for selected patients, with no recurrence noted during a median follow-up of 18.6 months.

Article Synopsis
  • * Researchers enrolled patients who underwent robotic prostate surgery, categorizing tumor locations based on pathology and imaging results, and assessed the effectiveness of side-specific lymph node removal.
  • * Results showed high detection accuracy for positive lymph nodes with a targeted approach, suggesting that tumor location-guided surgical strategies may lower the need for more extensive procedures while maintaining acceptable risk levels.

[Purpose] This study aimed to clarify the association between phase angle (PhA) and the level of independence in daily living among institutionalized super older females requiring nursing care. [Participants and Methods] This three-facility cross-sectional study enrolled 173 nursing home residents (mean age 91.0 years, standard deviation 4.

Various methods have been developed for measuring the surface tension of liquids, and the present study proposes a new method for measuring the surface tension of liquids. A small (9 mm diameter) round liquid surface was excited by sound waves with a common speaker. Nine liquids possessing various physical properties and functional groups were employed, and three resonance frequencies () were observed for each liquid in a frequency range of 20-180 Hz.
