Influences and Failure Analysis of the Interaction Between Melt and Gas on Double-Layer Gas-Assisted Extrusion Molding of Polymer Micro-Catheters
Published on 2025-02-15 by Zhong Ren, Xiaozhen Deng, Haibo Ji @MDPI
Abstract: Although the extrudate swelling, melt fracture, and extrusion deformation of polymer micro-catheters in traditional extrusion molding can be eliminated via the double-layer gas-assisted extrusion (DL-GAE) method, some failure problems are generated under unreasonable process conditions. To ascertain the reasons for failure in DL-GAE molding of polymer micro-catheters, the influences of the interaction between the melt and double assisted gas on the DL-GAE molding of polymer micro-catheters were [...]

Detection of Surgical Instruments Based on Synthetic Training Data
Published on 2025-02-15 by Leon Wiese, Lennart Hinz, Eduard Reithmeier, Philippe Korn, Michael Neuhaus @MDPI
Abstract: Due to a significant shortage of healthcare staff, medical facilities are increasingly challenged by the need to deploy current staff more intensively, which can lead to significant complications for patients and staff. Digital surgical assistance systems that track all instruments used in procedures can make a significant contribution to relieving the load on staff, increasing efficiency, avoiding errors and improving hygiene. Due to data safety concerns, laborious data annotation and the compl[...]
Our summary: Detection of Surgical Instruments using synthetic data improves object detection accuracy and generalization capabilities in OR settings. Key findings emphasize the importance of object visibility, occlusion, and inclusion of occlusion objects for enhancing detection performance.

Expression of Neuronal Nicotinic Acetylcholine Receptor and Early Oxidative DNA Damage in Aging Rat Brain—The Effects of Memantine
Published on 2025-02-14 by Ma?gorzata Anna Lewandowska, Agata Ró?ycka, Teresa Grzelak, Bartosz Kempisty, Pawe? Piotr Jagodzi?ski, Margarita Lianeri, Jolanta Dorszewska @MDPI
Abstract: Aging and age-related neurodegenerative disorders are characterized by the dysfunction or loss of brain nicotinic acetylcholine receptors (nAChRs), and these changes may be related to other senescence markers, such as oxidative stress and DNA repair dysfunction. However, the mechanism of nAChR loss in the aging brain and the modification of this process by drugs (e.g., memantine, Mem) are not yet fully understood. To study whether the differences in nAChR expression in the rat brain occur due to[...]
Our summary: Expression of nAChR and early oxidative DNA damage in aging rat brain, effects of Mem, protective antioxidative mechanisms.

Biofunctionalization of Collagen Barrier Membranes with Bone-Conditioned Medium, as a Natural Source of Growth Factors, Enhances Osteoblastic Cell Behavior
Published on 2025-02-13 by Harshitha Ashoka Sreeja, Emilio Couso-Queiruga, Clemens Raabe, Vivianne Chappuis, Maria B. Asparuhova @MDPI
Abstract: A key principle of guided bone regeneration (GBR) is the use of a barrier membrane to prevent cells from non-osteogenic tissues from interfering with bone regeneration in patients with hard tissue deficiencies. The aim of the study was to investigate whether the osteoinductive properties of bone-conditioned medium (BCM) obtained from cortical bone chips harvested at the surgical site can be transferred to a native bilayer collagen membrane (nbCM). BCM extracted within 20 or 40 min, which corresp[...]
Our summary: Biofunctionalization of collagen barrier membranes with bone-conditioned medium enhances osteoblastic cell behavior by transferring osteoinductive properties and promoting osteogenesis.

Modified Dynamic Movement Primitive-Based Closed Ankle Reduction Technique Learning and Variable Impedance Control for a Redundant Parallel Bone-Setting Robot
Published on 2025-02-13 by Zhao Tan, Yahui Zhang, Jiahui Yuan, Xu Song, Jialong Zhang, Guilin Wen, Xiaoyan Hu, Hanfeng Yin @MDPI
Abstract: Traditional fracture reduction relies heavily on the surgeon’s experience, which hinders the transmission of skills. This specialization bottleneck, coupled with the high demands on physical strength, significantly limits the efficiency of daily treatments in trauma orthopedics. Currently, most fracture surgery robots focus on open or minimally invasive reduction techniques, which inherently carry the risk of iatrogenic damage due to surgical incisions or bone pin insertions. Howev[...]
