AI Article Synopsis
- - A 75-year-old female with lung metastasis from head and neck squamous cell carcinoma exhibited a mass in the right lung area, alongside unusual 18-FDG uptake, without visible lung abnormalities on a CT scan.
- - Initial thoughts leaned towards lymphangitic spread of the cancer, indicating spread through lymphatic vessels.
- - However, follow-up imaging revealed a mass invading the right inferior pulmonary vein and significant decreased blood flow in specific lung lobes, leading to a diagnosis of right pulmonary venous occlusion instead.
Article Abstract
A 75-year-old nonsmoker and nonalcoholic female, known to have squamous cell carcinoma of the head and neck metastasized to the lungs, was found to have a mass at the right hilar/infra-hilar region and an unusual pattern of increased mild diffuse 18-fluorodeoxyglucose (18-FDG) uptake at the right mid-lower lobe location without any lung parenchymal abnormalities (confirmed by low dose CT scan of PET-CT). It was suspected to be the lymphangitic spread of the neoplasm; however, spectral detector CT (SDCT) imaging performed later not only confirmed the presence of a mass invading the right inferior pulmonary vein but showed a large area of significantly decreased perfusion in the right middle and lower lung lobes, leading to a change in the diagnosis to right pulmonary venous occlusion.

From a taxonomic point of view, Hymenoptera are subclassified into families: Apidae, including honeybees (Apis mellifera) and bumblebees (Bombus), and Vespidae, which, in turn, are divided into the subfamilies of Vespinae (wasps, including hornets, vespules, dolichovespules) and Polistinae (paper wasp). Hypersensitivity to Hymenoptera venom can be linked to immunological (IgE-mediated or non-IgE-mediated) and non-immunological mechanisms. Reactions are classified into local reactions, large local reactions, systemic reactions, toxic reactions, and unusual reactions.

A critical goal of vision is to detect changes in light intensity, even when these changes are blurred by the spatial resolution of the eye and the motion of the animal. Here, we describe a recurrent neural circuit in Drosophila that compensates for blur and thereby selectively enhances the perceived contrast of moving edges. Using in vivo, two-photon voltage imaging, we measured the temporal response properties of L1 and L2, two cell types that receive direct synaptic input from photoreceptors.

Ringed (Pusa hispida), bearded (Erignathus barbatus), spotted (Phoca largha), and ribbon (Histriophoca fasciata) seals are ice-associated seals that are important subsistence resources for coastal Alaska Native people. These seals are also mid- to upper trophic level Arctic predators and primary prey of polar bears (Ursus maritimus). We analyzed concentrations of 19 trace elements in seal liver, kidney, muscle, and blubber, including arsenic, cadmium, lead, mercury, and vanadium due to their potential toxicity.

SEASONAL VARIATION OF BLOOD ANALYTES ASSOCIATED WITH SKIN HEALTH IN ALASKAN ICE SEALS.
J Zoo Wildl Med
December 2024
Alaska SeaLife Center, Seward, AK 99664.
Recent unusual mortality events involving skin pathology in bearded (), ringed (), and spotted seals () in Alaska highlight the potential sensitivity of ice-associated species to the complex effects of climate change. The regulation of thyroid hormones, cortisol, and vitamin A have been shown to play essential roles in skin health and seasonal molt in some pinnipeds. Unfortunately, the lack of available reference data for healthy Alaskan ice seals has prevented the adequate evaluation of these factors in cases associated with mortality events.
