概括

在火葬前对心脏植入式电子设备 (CIED) 进行手术,这是标准的做法. 这项研究发现,较小的CIED可以安全地在现场进行火葬,而较大的设备则存在风险.

科学领域:

医疗器械安全医疗器械安全
法医科学法医科学法医科学
材料科学材料科学材料科学

背景情况:

用心脏植入式电子设备 (CIED) 的患者的火葬通常需要进行手术,以防止爆炸.
爆炸可能与宗教或个人信仰相冲突,并构成职业危险.

研究的目的:

开发一个ex vivo模型来评估CIED在火葬过程中的行为.
评估与火葬CIED相关的风险.

主要方法:

七个CIED受到弹子/声音测试,冲击测试和气体分析.
高速摄像机和麦克风记录了热失效事件.
气色谱-质谱识别了释放的气体.

主要成果:

像植入式循环记录器和无心脏起器这样的较小设备显示出最小的动能和冲击风险.
较大的设备 (起器,植入式心脏除器) 在500°C以下爆炸,产生>120 dB的声音和破坏结构.
在职业限制范围内检测到微量和化.

结论:

所有测试的CIED在低于标准火葬温度的温度下爆炸.
较小的CIED可以安全地在现场焚烧,因为风险最小.
较大的CIED存在动能释放,损伤和爆炸的风险,需要在全尺寸火葬室进行进一步的尸体研究.

Bacterial Signaling

Bacterial Signaling

Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
