Bitewing Radiography Semantic Segmentation Base on Conditional Generative Adversarial Nets [PDF]

open access: yesarXiv, 2018
Currently, Segmentation of bitewing radiograpy images is a very challenging task. The focus of the study is to segment it into caries, enamel, dentin, pulp, crowns, restoration and root canal treatments. The main method of semantic segmentation of bitewing radiograpy images at this stage is the U-shaped deep convolution neural network, but its accuracy

scHeteroNet: A Heterophily‐Aware Graph Neural Network for Accurate Cell Type Annotation and Novel Cell Detection

open access: yesAdvanced Science, EarlyView.
scHeteroNet) is a novel graph neural network model that explicitly addresses heterophily in single‐cell sequencing data enabling accurate cell type annotation and novel cell type discovery. By leveraging heterophily‐aware message passing and novelty propagation mechanisms, scHeteroNet achieves superior performance in both cell annotation and detection ...

Bruton tyrosine kinase inhibitors in the management of Waldenström macroglobulinemia

open access: yesAmerican Journal of Hematology, Volume 98, Issue 2, Page 338-347, February 2023., 2023
Abstract Bruton tyrosine kinase (BTK) inhibitors have taken a central role in the management of patients with Waldenström macroglobulinemia and are the only agents approved by the Food and Drug Administration (FDA) to treat these patients. Although associated with high rates of durable responses, unmet needs with BTK inhibitor therapy include ...

Understanding the Dynamics of Inflammatory Cytokines in Endodontic Diagnosis: A Systematic Review

open access: yesDiagnostics
The primary aim of this literature review is to delineate the key inflammatory cytokines involved in the pathophysiology of pulp inflammation. By elucidating the roles of these cytokines, a deeper comprehension of the distinct stages of inflamed pulp can

A Molecularly Defined Medullary Network for Control of Respiratory Homeostasis

open access: yesAdvanced Science, EarlyView.
The dynamic interplay between central respiratory chemoreceptors and the respiratory central pattern generator is essential for maintaining stable respiratory rhythm and patterns, particularly during sleep. This study offers novel insights into the anatomical, molecular, and functional characteristics of a medullary network involving the nucleus ...

Economic impacts and nutritional outcomes of the 2017 floods in Bangladeshi Shodagor fishing families

open access: yesAmerican Journal of Human Biology, Volume 35, Issue 1, January 2023., 2023
Abstract Objectives As climate change continues to increase the frequency and severity of flooding in Bangladesh and globally, it becomes increasingly critical to understand the pathways through which flooding influences health outcomes, particularly in lower‐income and subsistence‐based communities.

Dissecting the Spatial and Single‐Cell Transcriptomic Architecture of Cancer Stem Cell Niche Driving Tumor Progression in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
A single‐cell and spatial transcriptional atlas reveals the architecture of human gastric cancer stem cell (CSC) niche and the developmental trajectory of CSCs. These CSCs interact with immunosuppressive immune cells thereby constructing immune‐suppressive niche, and inflammatory cancer‐associated fibroblast (iCAFs) to enhance stemness through ...

PPY‐Induced iCAFs Cultivate an Immunosuppressive Microenvironment in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
Pancreatic ductal adenocarcinoma features abundant stromal components that hinder therapy efficacy. Single‐cell RNA sequencing analysis combined with experiments identified PPY, a gastrointestinal hormone, as a novel inducer of immunosuppressive iCAFs. Mechanistic studies revealed that PPY activates the non‐canonical NF‐κB pathway via EGFR.

Some factors involved in mechanical instrumentation in the root canal of a permanent tooth [PDF]

open access: yes, 1969
Endodontics can best be defined in the words of the preface of the Bulletin on Endodontics prepared by the University of Toronto Dental School, This states that "endodontics is the union of two Greek words 'endo' within and 'odontos' a tooth.

Extracellular Vesicle‐Packaged Linc‐ZNF25‐1 from Pancreatic Cancer Cell Promotes Pancreatic Stellate Cell Uptake of Asparagine to Advance Chemoresistance

open access: yesAdvanced Science, EarlyView.
This study explores the role of gemcitabine (GEM)‐resistant pancreatic cancer‐derived extracellular vesicles (EVs) in activating pancreatic stellate cells (PSCs) and promoting extracellular matrix production. GEM‐resistant cells release higher levels of asparagine (Asn), which triggers PSC activation. Long noncoding RNA sequencing identified linc‐ZNF25‐
