Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance

Advanced Materials, EarlyView.
This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

Laparoscopic anatomical liver resection after complex blunt liver trauma: a case report

Surgical Case Reports, 2018
Background Various minimally invasive therapies are important adjuncts to management of hepatic injuries. However, there is a certain subset of patients who will benefit from liver resection, but there are no reports in the literature on laparoscopic ...

A multi-scale pyramid of 3D fully convolutional networks for abdominal multi-organ segmentation [PDF]

arXiv, 2018
Recent advances in deep learning, like 3D fully convolutional networks (FCNs), have improved the state-of-the-art in dense semantic segmentation of medical images. However, most network architectures require severely downsampling or cropping the images to meet the memory limitations of today's GPU cards while still considering enough context in the ...

Predictors of postoperative hypocalcemia occurring after a total thyroidectomy: results of prospective multicenter study

BMC Surgery, 2018
Background Thyroid surgeries are among the most common operations performed in the world. Hypocalcemia following total thyroidectomy is a common complication that is sometimes difficult to correct.

Homogenization of oxygen transport in biological tissues [PDF]

arXiv, 2014
In this paper, we extend previous work on the mathematical modeling of oxygen transport in biological tissues (Matzavinos et al., 2009). Specifically, we include in the modeling process the arterial and venous microstructure within the tissue by means of homogenization techniques.

The CRL7FBXW8 Complex Controls the Mammary Stem Cell Compartment through Regulation of NUMB Levels

Advanced Science, EarlyView.
In breast cancer (BC), NUMB loss of function (LOF) is common and mainly driven by protein hyper‐degradation. The CRL7FBXW8 complex is the E3 ligase responsible for NUMB degradation. Inhibition of CRL7FBXW8 in NUMB‐LOF BC cells restores NUMB levels, and decreases the number of cancer stem cells and tumorigenic ability in vivo. Targeting CRL7FBXW8 offers

AAVR Expression is Essential for AAV Vector Transduction in Sensory Hair Cells

Advanced Science, EarlyView.
Decreased sensitivity to AAV vector transduction in the outer hair cells (OHCs) of adult mice is primarily attributed to reduction of AAVR (Kiaa0319l; Au040320). Knockout of AAVR reduces AAV vector transduction efficiency in both inner hair cells (IHCs) and OHCs in neonatal mice.
