A Mathematical Model of Cellular Aggregation Predicts Patterns of Tau Accumulation in Neurodegenerative Disease

open access: yesAdvanced Science, EarlyView.
A minimal computational model of cellular aggregate formation in neurodegenerative disease, encompassing two competing processes: cell‐autonomous and cell‐to‐cell triggers of aggregation, is presented. Despite its simplicity, the model can reproduce the aggregate patterns observed in post‐mortem brain images from the primary tauopathy Progressive ...

Positron Escape from Type Ia Supernovae

open access: yes, 1999
We generate bolometric light curves for a variety of type Ia supernova models at late times, simulating gamma-ray and positron transport for various assumptions about the magnetic field and ionization of the ejecta.

Micro/Nanorobots for Combating Brain Disorders: Challenges, Advances, and Perspectives

open access: yesAdvanced Science, EarlyView.
Micro/nanorobots (MNRs) offer a transformative approach for precision therapy in brain disorders. By overcoming biological barriers and enabling controlled propulsion, targeted delivery, and real‐time imaging/tracking, MNRs pave the way toward effective, minimally invasive treatments. This review outlines the interplay between brain disease challenges,

Defect Engineering in Semiconductor Photocatalysts: Enhancing Photocatalytic Activity for Green Energy Production

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
By creating anion and cation vacancies, scientists fine‐tune semiconductor bandgaps and extend light absorption, boosting charge separation in photocatalysts. Surface defects enhance reactant adsorption and carrier transport, while controlled bulk defects curb recombination.

Discrepancy Between Radiographic and Pathological Response Assessment in Neoadjuvant Treatment for Pancreatic Cancer: A Comparison Between Neoadjuvant Chemotherapy and Neoadjuvant Chemoradiotherapy

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study investigated the association between radiographic and pathological response assessments among patients with pancreatic cancer receiving neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy. The present study revealed that discrepancies between radiographic and histological responses may differ according to the type of therapy ...

Prognostic Significance of GLIM‐Defined Malnutrition in Patients With Resectable Pancreatic Adenocarcinoma Following Upfront Surgery

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The GLIM criteria are effective prognostic predictors in patients with resectable PDAC undergoing upfront surgery. Preoperative nutritional assessment using these criteria may contribute to determining treatment plans for resectable PDAC. ABSTRACT Aim Regarding the resectability of pancreatic adenocarcinoma (PDAC), not only anatomical factors but also ...

Outcomes of Resected Cases of Pancreatic Ductal Adenocarcinoma Patients With Unexpected Postoperative Uncovering Noncurative Factors: A Multicenter Retrospective Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
We aimed to refine treatment strategies for resected cases of pancreatic ductal adenocarcinoma in patients with unexpectedly uncovered postoperative noncurative factors. Cases with unexpected postoperative uncovering noncurative factors had significantly poorer prognoses than those without such factors.

Learning Curve Effect in Reducing Local Recurrence Rate After Resection of Pancreatic Cancer With Arterial Abutment: A Single‐Center Retrospective Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Pancreatectomy for pancreatic ductal adenocarcinoma (PDAC) with arterial abutment is a complex, high‐risk surgery. We aimed to investigate the clinicopathological features, risk factors, and learning curve for local recurrence after pancreatectomy for PDAC with arterial abutment.
