Application of Structured-Light 3-D Scanning to the Documentation of Plastic Fingerprint Impressions: A Quality Comparison with Traditional Photography.

Plastic fingerprint impressions found at crime scenes are often too delicate for collection, leaving photography as the best option for documentation. However, traditional photography techniques can be inadequate in documenting minute 3-D details due to limitations of the camera and lighting conditions. This study investigated the feasibility of applying commercially available structured-light 3-D scanners in the documentation of plastic prints.

[Effects of acupuncture in Siguan points on man-machine counteraction in respiratory failure patients during mechanical ventilation].

Objective: To investigate the value of applying acupuncture in patients with respiratory failure Sixty (RF) during mechanical ventilation (MV) when there happened man-machine counteraction.

Methods: RF patients with nonsynchronous spontaneous breath (SB) during mechanical ventilation were divided into two groups randomly, 30 in each group. The control group treated with intravenous midazolam injection, and the treated group with acupuncture in Siguan points combined intravenous midazolam injection to maintain synchronized SB and MV, and to calm patients.
