Differential Diagnostic Value of Parathyroid 99mTc-MIBI SPECT/CT in MIBI Uptake Lesion

, 2020
Abstract Background: To investigate the role of parathyroid technetium-99m-hexakis2-methoxy-2-methylpropylisonitrile (99mTc-MIBI) single photon emission computed tomography/ computed tomography (SPECT/CT) combined with the serum calcium (Ca) and serum parathyroid hormone (PTH) in the differential diagnosis of MIBI uptake lesion.

Post‐Translational Regulation of CD8+ T Cell Fate and Dysfunction in Tumor Immunity

Advanced Science, Volume 13, Issue 21, 13 April 2026.
This review delineates how post‐translational modifications (PTMs) function as a central regulatory interface governing CD8+ T cell activation, differentiation, persistence, and exhaustion in antitumor immunity. By integrating antigenic, metabolic, and microenvironmental cues, diverse PTM programs coordinate transcriptional and chromatin states that ...

Hyper-Rayleigh scattering in centrosymmetric systems [PDF]

, 2015
Hyper-Rayleigh scattering (HRS) is an incoherent mechanism for optical second harmonic generation. The frequency-doubled light that emerges from this mechanism is not emitted in a laser-like manner, in the forward direction; it is scattered in all ...

The Potential Role of Baseline FT3/FT4 Ratio as a Prognostic Biomarker for Patients With Ischemic Non‐Obstructive Coronary Artery Disease

Clinical Cardiology, Volume 49, Issue 4, April 2026.
A low FT3/FT4 ratio indicates a significant increase in the risk of major adverse cardiovascular events in INOCA patients, or a novel biomarker for prognosis. ABSTRACT Background Ischemia with non‐obstructive coronary artery disease (INOCA) is associated with an increased risk of major adverse cardiovascular events (MACE).

CCL2 and Lactate from Chemotherapeutics-Treated Fibroblasts Drive Malignant Traits by Metabolic Rewiring in Low-Migrating Breast Cancer Cell Lines

Antioxidants
While cytostatic chemotherapy targeting DNA is known to induce genotoxicity, leading to cell cycle arrest and cytokine secretion, the impact of these drugs on fibroblast–epithelial cancer cell communication and metabolism remains understudied.

Diagnostic capabilities of I-131, TI-201, and Tc-99m-MIBI scintigraphy for metastatic differentiated thyroid carcinoma after total thyroidectomy. [PDF]

, 2005
We investigated the diagnostic capabilities of I-131, Tl-201, and Tc-99m-MIBI (hexakis-2-methoxyisobutyl- isonitrile) scintigraphy for thyroid cancer metastases after total thyroidectomy over the entire body and for every locus before and after thyroid ...

Adventitial Niches, Complement and Inflammation in Pulmonary Vascular Disease: Current Status and Future Directions

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Local complement production by pulmonary artery adventitial fibroblasts, activated intracellularly by CFD and CFB and extracellularly by GZMK+ CD8 T cells, and its secretion in soluble form and within EVs promotes macrophage and T cell chemotaxis and activation.
