Radionuclide and thermographic studies using 67Ga-citrate and 111In-bleomycin were performed in 129 patients with laryngeal cancer, chemodectoma of the neck, retinoblastoma, rhabdomyosarcoma of the orbital and facial soft tissues and cancer of the tongue. Elevated amounts of the radiopharmaceutical drug were found in patients with tumors. In thermographic studies higher thermogenic activity corresponding to the tumor was noted. Radionuclide thermographic studies extend diagnostic opportunities for head and neck tumors.

Breast cancer is one of the leading causes of death for women worldwide, and early detection can help reduce the death rate. Infrared thermography has gained popularity as a non-invasive and rapid method for detecting this pathology and can be further enhanced by applying neural networks to extract spatial and even temporal data derived from breast thermographic images if they are acquired sequentially. In this study, we evaluated hybrid convolutional-recurrent neural network (CNN-RNN) models based on five state-of-the-art pre-trained CNN architectures coupled with three RNNs to discern tumor abnormalities in dynamic breast thermographic images.

Glioblastoma (GBM) is a highly aggressive malignant brain tumour which presents a significant challenge due to the limited effectiveness of current surgical and chemotherapeutic approaches. In this study, we have developed TMZ16e and gold nanoparticles coencapsulated thermosensitive liposomes modified with anti-EphA3 (anti-EphA3-TMZ16e-GNPs-TSL) delivered via the intranasal route to achieve photothermal chemotherapy (PCT) for improving the therapeutic effects of GBM. The prepared anti-EphA3-TMZ16e-GNPs-TSL were spherical with a particle size of 173.

Medical thermography is a non-invasive technique that allows the measurement of the temperature of the human body surface, exploiting the heat emitted by the body through the skin in the form of infrared electromagnetic radiation. Recently, smartphone-based thermography (ST) has drawn considerable attention. This scoping review (SR) aims to describe its current applications and reliability based on currently available research findings, also taking into account the medico-legal implications linked to its use.

Introduction: In December, it is common to enjoy mulled wine, often believed to warm the body. While alcohol can cause peripheral vasodilation, it remains unclear whether it truly increases body warmth or is merely a subjective sensation. This study aimed to evaluate the warming effect of mulled wine using thermography.
