Amyotrophic lateral sclerosis(ALS)is a progressive neurodegenerative disorder characterized by the degeneration of motor neurons in the brain and spinal cord,leading to muscle weakness,paralysis,and ultimately death(Cleveland and Rothstein,2001).Frontotemporal lobar degeneration(FTLD)is a neurodegenerative disease affecting the frontal and temporal lobes of the brain,leading to changes in behavior,personality,and language(Van Langenhove et al.,2012).Both ALS and FTLD are classified as proteinopathies in which abnormal protein aggregation and accumulation in neurons contribute to the disease *** in sarcoma(FUS)is a DNA/RNA-binding protein involved in various cellular processes,including transcriptional regulation,RNA splicing,and DNA *** in the FUS gene have been linked to familial ALS,highlighting the importance of FUS in the disease pathogenesis(Vance et al.,2009).In ALS and FTLD,aberrant post-translational modifications(PTMs)of FUS,such as phosphorylation,acetylation,and methylation,have been implicated in the promotion of FUS aggregation and neurotoxicity(Choi et al.,2023).Therefore,understanding the regulatory mechanisms of FUS PTMs is crucial for developing targeted therapies against these diseases.

The cingulum is the neural fiber bundle that connects the basal forebrain and medial temporal lobe. The cingulum contains the medial cholinergic pathway, which originates from the basalis nucleus of Meynert in the basal forebrain. Therefore, it is important for memory function （Malykhin et al., 2008; Hong and Jang, 2010）. In the past, identification of the cingulum on conventional brain MRI has been impossible because it cannot discern the cingulum from other adjacent structures. Diffusion tensor tractography （DTT）, derived from diffusion tensor imaging （DTI）, allows three-dimensional visualization and estimation of the cingulum （Malykhin et al., 2008）.

Three types of water-based condensational growth systems, which can enable particles to grow in size to facilitate sampling and subsequent chemical analysis, were evaluated. The first one is a mixing type growth system where aerosols are mixed with saturated water vapor, the second one is a thermal diffusive growth system where warm flow enters cold-walled tube, and the third one is a laminar flow type where cold flow enters a warm wet-wall tube. Hygroscopic sodium chloride （NaCl）, ammonium sulfate （（NH4）2SO4） and ammonium nitrate （NH4N03）, and non-hygroscopic polystyrene latex （PSL） particles, in the size range of 50-400 nm, were used to determine their growth factors through the growth systems. Our data showed that the third-type growth system could enable particles to grow most efficiently regardless of their hygroscopic property. Collection efficiency of particles in the size range of 0.05-2.5 μm, in a continuous aerosol sampler after they passed through the third-type growth system was about 100%, suggesting that the third-type growth system would he the most useful among the tested growth systems for sampling and subsequent chemical analysis of fine and ultrafine particles.

Recently, it has been suggested that the guideline for adjuvant radiotherapy （ART） following radical prostatectomy （RP） sponsored by the American Urological Association and American Society for Radiation Oncology （AUA/ASTRO） may result in a significant overtreatment. Thus, the objective of the present study was to refine the AUA/ASTRO guideline for ART in patients at risk for biochemical recurrence （BCR） after RP. To this end, we reviewed our prospectively maintained database and selected 193 patients who met the AUA/ASTRO ART criteria. With a median follow-up of 24.0 months, BCR rate was 17.6% （34/193）. When stratified by the Gleason score, BCR rate in men with Gleason score 6 was 6.8%. There was no significant association between BCR-free survival and surgical margin （P= 0.690） and pathologic stage （P= 0.353） in patients with the Gleason score 6. However, in patients with positive surgical margins （PSMs）/pathologic stage ≥T3, there was a significant difference in BCR-free survival according to Gleason score （≤7 vs8-10, P= 0.047）. Multivariate Cox regression analysis demonstrated that pathologic stage ≥T3 （HR = 2.106; P = 0.018）, PSMs （HR = 2.411; P = 0.003）, and pathologic Gleason score 8-10 （HR = 4.715; P 〈 0.001） were independent predictors of BCR after RP. Therefore, in addition to pathologic stage 〉T3 and PSMs, Gleason score 8-10 predicts 8CR after RP. In patients with Gleason score 6, observation rather than ART may be more appropriate regardless of stage and surgical margin status.
