M2U-Net: Effective and Efficient Retinal Vessel Segmentation for Resource-Constrained Environments [PDF]

arXiv, 2018
In this paper, we present a novel neural network architecture for retinal vessel segmentation that improves over the state of the art on two benchmark datasets, is the first to run in real time on high resolution images, and its small memory and processing requirements make it deployable in mobile and embedded systems.

Microsurgical Robotic System for Myringoplasty: Feasibility Study

Laryngoscope Investigative Otolaryngology, Volume 10, Issue 3, June 2025.
We evaluated a prototype of a new microsurgical robot designed for use in otology. The system was tested in a rabbit myringoplasty procedure, demonstrating its capability to perform microsurgery in narrow and deep regions. ABSTRACT Objective Otological surgery requires exceptional precision and advanced surgical skills, particularly for procedures ...

Bioprinting Perfusable and Vascularized Skeletal Muscle Flaps for the Treatment of Volumetric Muscle Loss

Advanced Healthcare Materials, Volume 14, Issue 13, May 16, 2025.
Volumetric muscle loss (VML) due to trauma or surgery, often leads to physical impairments. Traditional treatments rely on autologous flaps, limited by muscle availability often leading to donor site morbidity. This study presents multimodal bioprinting as an innovative approach for fabricating vascularized muscle flaps with 3D‐printed macrovessels ...

Motor‐Free Soft Robots for Cancer Detection, Surgery, and In Situ Bioprinting

Advanced Healthcare Materials, Volume 14, Issue 14, May 28, 2025.
Novel motor‐free soft robots for cancer detection, surgery, and in situ bioprinting–are presented. This master‐slave system is constructed from soft fibrous syringe architectures, removing the need for electrical motors and complex control mechanisms, while reducing the physical tremors.

Rapid Blood Clot Removal via Remote Delamination and Magnetization of Clot Debris

Advanced Science, Volume 12, Issue 17, May 8, 2025.
A programmable colloidal microswarm is developed to quickly detach blood clots and enable rapid recanalization, with the detached debris functioning as a magnetic “debris‐robot” that can be efficiently propelled and retrieved via catheter suction, which could significantly save time compared to the critical “Golden 6 hours” window for ischemic stroke ...

Drain Fluid Amylase as an Early Negative Predictor of Salivary Fistula Following Free Flap Reconstruction

Microsurgery, Volume 45, Issue 4, May 2025.
ABSTRACT Objectives Salivary fistula is a known complication following head and neck free flap reconstruction involving the aerodigestive tract. We sought to examine the association between surgical drain fluid amylase and salivary fistula formation during postoperative hospitalization. Methods Eighty patients who underwent head and neck reconstruction

Does socioeconomic status influence the choice of surgical technique in abdominal rectal cancer surgery?

Colorectal Disease, Volume 27, Issue 5, May 2025.
Abstract Aim This study aimed to estimate the impact of socioeconomic status on the probability of receiving open (OPEN) or minimally invasive surgery (MIS) for curative abdominal rectal cancer resection. Methods All patients diagnosed with rectal cancer clinical Stage I–III during the period 2010–2021 who underwent curative abdominal resection surgery,

A pectin acetyl‐transferase facilitates secondary plasmodesmata formation and RNA silencing movement between plant cells

The Plant Journal, Volume 122, Issue 3, May 2025.
SUMMARY Some silencing small (s)RNAs, comprising micro (mi)RNAs and small‐interfering (si)RNAs, move between plant cells to orchestrate gene expression and defense. Besides possible redundancy or embryo lethality, a prevalent challenge in genetic studies of mobile silencing is to discriminate bona fide alterations to sRNA movement from impaired cell ...
