TA-Net: Topology-Aware Network for Gland Segmentation [PDF]

arXiv, 2021
Gland segmentation is a critical step to quantitatively assess the morphology of glands in histopathology image analysis. However, it is challenging to separate densely clustered glands accurately. Existing deep learning-based approaches attempted to use contour-based techniques to alleviate this issue but only achieved limited success. To address this

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

Advanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Regulation of Prolactin Release at the End Stage of Chicken Embryogenesis

The Journal of Poultry Science, 2022
Difference of onset of increase of PRL content in the anterior pituitary gland and plasma PRL concentration during the late stage of chicken embryogenesis is well known. To investigate the disagreement, changes in PRL content and PRL mRNA levels, and the

“Therapies Through Gut:” Targeted Drug Delivery for Non‐Gastrointestinal Diseases by Oral Administration

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach

Coordinated Role of Autophagy and ERAD in Maintaining Neuroendocrine Function by Preventing Prohormone Aggregation

Advanced Science, EarlyView.
By studying the maturation mechanisms of vasopressin (AVP), this manuscript identifies FAM134B‐mediated ER‐phagy as a critical pathway for degrading both aggregated proAVP and the key ERAD component, HRD1. HRD1 induction mitigates proAVP aggregation and support AVP neuron function in the absence of autophagy.

Cellular and molecular specificity of pituitary gland physiology.

Physiological Reviews, 2012
The anterior pituitary gland has the ability to respond to complex signals derived from central and peripheral systems. Perception of these signals and their integration are mediated by cell interactions and cross-talk of multiple signaling transduction ...

Morphology-inspired Unsupervised Gland Segmentation via Selective Semantic Grouping [PDF]

arXiv, 2023
Designing deep learning algorithms for gland segmentation is crucial for automatic cancer diagnosis and prognosis, yet the expensive annotation cost hinders the development and application of this technology. In this paper, we make a first attempt to explore a deep learning method for unsupervised gland segmentation, where no manual annotations are ...
