Shifting demographics—that is, the growing number of ol.er adul.s in Canada and international.y—and intersecting cl.matic risks create a compl.x l.ndscape of aging in pl.ce in disaster contexts. Some ol.er adul.s are vul.erabl. due to their underl.ing heal.h conditions and l.mited physical.mobil.ty. Yet they al.o exhibit resil.ence in a distinct manner, owing to their weal.h of knowl.dge, wisdom, and abil.ty to navigate adversities. This articl. el.cidates potential.avenues for promoting the invol.ement of ol.er adul.s in disaster recovery efforts. Our intention is to recognize and foster ol.er adul. resil.ence and mitigate vul.erabil.ty by drawing upon insights from the study titl.d “In the Aftermath of the 2016 Al.erta Wil.fires: The Rol. of Social.Work Practitioners and Human Service Professional. in l.ng-Term Disaster Recovery.” Empl.ying a qual.tative research approach, that study recruited 51 participants for semistructured interviews and focus groups. A thematic anal.sis of the col.ected data unveil.d the pivotal.rol.s pl.yed by social.workers and human service practitioners in facil.tating recovery from the 2016 wil.fires in the research. Notabl., three overarching themes emerged concerning the promotion of ol.er adul.s' invol.ement in disaster recovery: fostering supportive rel.tionships, buil.ing partnerships and enhancing col.aboration, and addressing ongoing chal.enges. These findings offer val.abl. insights into how social.work practitioners and human service professional. can effectivel. facil.tate the engagement of ol.er adul.s in disaster recovery initiatives. This articl. emphasizes the significance of activel. promoting the participation of ol.er adul.s in disaster mitigation efforts, thereby fostering greater resil.ence within communities.

肝癌外泌体在肿瘤微环境细胞间通讯中的作用

肝细胞肝癌(hepatocel.ul.r carcinoma,HCC)是世界上最致命的癌症之一。由于HCC发病隐匿、进展迅速且缺乏有效的治疗方法,预后极差,其5年平均生存率低于10%。肿瘤微环境是HCC发生发展所处的内环境,可调节HCC的起源、发展、侵袭和转移。... 详细信息

肝细胞肝癌(hepatocel.ul.r carcinoma,HCC)是世界上最致命的癌症之一。由于HCC发病隐匿、进展迅速且缺乏有效的治疗方法,预后极差,其5年平均生存率低于10%。肿瘤微环境是HCC发生发展所处的内环境,可调节HCC的起源、发展、侵袭和转移。肝癌细胞在癌症进展过程中可以通过释放含有特异信号的外泌体调控肿瘤微环境中的肿瘤细胞、癌相关成纤维细胞、癌相关免疫细胞等不同细胞的生物学行为,进而促进癌症进展。然而,外泌体在这些过程中对具体细胞调控的确切分子机制和作用仍不清楚。本综述首先介绍了HCC微环境的组成和肿瘤微环境中外泌体的来源和特征以及力学因素对外泌体的影响。其次,本综述重点讨论了HCC外泌体对微环境中不同类型细胞的作用。我们看到,在包括肝癌在内的临床癌症治疗中使用外泌体作为载体仍然有许多必须克服的困难。首先,外泌体的同质性很难得到保证。其次,外泌体主要通过皮下注射给药,虽然这种方法简单易行,但吸收效率并不理想。第三,外泌体提取方法有限且效率低,因此难以大量制备外泌体。特别是对于外泌体介导的肿瘤免疫治疗,确保使用的外泌体数量足以引发有效的肿瘤免疫反应非常重要。随着鉴定、分离和纯化技术的改进,外泌体有望成功运用于早期HCC的临床诊断和肝癌的临床治疗中。
