Pancreatic Well-Differentiated Neuroendocrine Tumors are Frequently Undergraded on Endoscopic Ultrasound-Guided Fine Needle Biopsy Sampling: A Single Institutional Experience.

. To determine the accuracy of grading pancreatic well-differentiated neuroendocrine tumors (PanNETs) on endoscopic ultrasound-guided fine needle biopsy (EUS-FNB). .

Impact of declared wildfire disasters on survival of lung cancer patients undergoing radiation.

Purpose: Oncological treatments, such as radiotherapy, which requires consistent electricity, the presence of specialized clinical teams, and daily patient access to treatment facilities, are frequently disrupted by extreme weather events, posing several health hazards to patients. This study explores the association between declared wildfire disasters during radiotherapy and overall survival among patients with non-small cell lung cancer (NSCLC).

Methods: The study population consisted of 202,935 adults with inoperable Stage III NSCLC, who initiated radiotherapy from 2004 through 2019.

Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the transatlantic slave trade.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

Clinicopathologic findings in a cohort of metastases to the stomach.

Aims: Metastatic tumors to the stomach can mimic primary gastric adenocarcinoma or be subtle and difficult to identify. The current study aimed to characterize the clinicopathology of metastases to the stomach to aid in diagnosis.

Methods And Results: Forty-three metastatic tumors and 30 primary gastric adenocarcinoma cases were reviewed.

Insights into the methodology of acetyl-CoA carboxylase inhibition.

Acetyl-CoA carboxylase catalyzes the first committed and regulated step in fatty acid synthesis in all animals, plants and bacteria. In most Gram-positive and Gram-negative bacteria, the enzyme is composed of three proteins: biotin carboxylase, biotin carboxyl carrier protein and carboxyltransferase. The reaction consists of two half-reactions.
