New Concepts of Mechanisms of Intestinal Cholesterol Absorption
The small intestine is a unique organ providing dietary and reabsorbed biliary cholesterol to the body. However, the molecular mechanisms whereby cholesterol is absorbed have not yet been fully understood.

Automatic breast cancer grading in lymph nodes using a deep neural network [PDF]
The progression of breast cancer can be quantified in lymph node whole-slide images (WSIs). We describe a novel method for effectively performing classification of whole-slide images and patient level breast cancer grading. Our method utilises a deep neural network.

Combining mammaglobin and carcinoembryonic mRNA markers for early detection of micrometastases from breast cancers - a molecular study of 59 patients [PDF]
Introduction: As many as 30% of node-negative breast cancer patients relapse within five years, suggesting that current histological detection methods are inadequate for identifying metastatic disease. Detecting small number of cancer cells in the breast

Establishment and biological characterization of radioresistant colorectal cancer cell lines
Under ionizing radiation exposure, radiation‐sensitive cancer cells exhibit oxidative stress and DNA damage, while radiation‐resistant cancer cells exhibit strong antioxidant properties and DNA damage repair. Radiotherapy resistance is a major cause of recurrence and metastasis in colorectal cancer (CRC).

The surface coat of chylomicrons: lipid chemistry
Chylomicrons from the thoracic duct lymph of dogs fed corn oil were isolated by centrifugation and disrupted by either freezing and thawing or rotary evaporation and rehydration.

Enhancement of rat lymphatic lipid transport by glucose or amino acids ingestion
To elucidate the effect of simultaneously fed carbohydrate or protein on lipid absorption, lymphatic lipid transports in the rat intestine were observed with or without simultaneous feeding of glucose or amino acids. A lipid emulsion containing 40 μmol/h

Cluster-Based Learning from Weakly Labeled Bags in Digital Pathology [PDF]
To alleviate the burden of gathering detailed expert annotations when training deep neural networks, we propose a weakly supervised learning approach to recognize metastases in microscopic images of breast lymph nodes. We describe an alternative training loss which clusters weakly labeled bags in latent space to inform relevance of patch-instances ...

The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.
