Case report: Imaging findings of true thymic hyperplasia at 18F-FDG PET/CT in an infant

Frontiers in Oncology, 2023
True thymic hyperplasia (TTH) in children is rare and difficult to distinguish from other thymic tumors such as thymoma and thymic carcinoma. A 3‐year‐old girl underwent an 18F‐fluorodeoxyglucose (18F‐FDG) positron emission tomography (PET)/computed ...

The Difference in Maximum Standardized Uptake Value among Lung Adenocarcinomas Located at the Upper and Lower Zone on PET/CT [PDF]

Respiration, 2015
<b><i>Background:</i></b> Findings on ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) are surrogate markers of malignancy in lung adenocarcinoma. Breathing during PET/CT can substantially reduce the maximum standardized uptake value (maxSUV) of lung tumors when they are ...

Quantitative pretreatment VOI analysis of liver metastases 99mTc-MAA SPECT/CT and FDG PET/CT in relation with treatment response to SIRT [PDF]

, 2013
Using quantitive VOI analysis, the percentage Tc-99m-MAA uptake and SUVmax and mean values of liver metastases obtained prior to SIRT were related to treatment response using both a lesion-based and clinical dichotomous approach. Based on the VOI % of Tc-

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

The maximum standardized uptake value of ¹⁸ F-FDG PET scan to determine prognosis of hormone-receptor positive metastatic breast cancer

BMC Cancer, 2013
Background Whether PET scan maximum standard uptake value (SUVmax) could differentiate luminal A from luminal B and help predict the survival of metastatic breast cancer (MBC) patients with luminal subtype is still unknown and need to be investigated ...

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

Molecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

Relations between the standardized uptake value of 18F-FDG-PET/CT and demographic, clinical, pathological, and radiological factors in lung cancer

Egyptian Journal of Chest Disease and Tuberculosis
Background FDG-PET/CT is considered a noninvasive method for mediastinal staging and functional assessment of lung cancer. Standardized uptake value maximum (SUVmax) estimates the activity of the tumor and its aggressiveness.

18F-FDG-PET/CT can be used to predict distant metastasis in hypopharyngeal squamous cell carcinoma

Journal of Otolaryngology - Head and Neck Surgery, 2022
Background Hypopharyngeal squamous cell carcinoma (HPSCC) has a high rate of distant metastasis, resulting in poor prognosis. The role of the maximum standardized uptake value (SUVmax), which was assessed via pretreatment 18-fluorodeoxyglucose positron ...

Genetic distance predicts trait differentiation at the subpopulation but not the individual level in eelgrass, Zostera marina. [PDF]

, 2018
Ecological studies often assume that genetically similar individuals will be more similar in phenotypic traits, such that genetic diversity can serve as a proxy for trait diversity.
