In order to understand the three-dimensional gross anatomy of the heart, it is important to observe the inner structures of the chambers and the spatial relation between the valves and the ventricles. In our dissecting laboratory, we designed a guide to dissection of the heart according to the following procedures. First, we observe the surface anatomy of the heart in the pericardial cavity, remove the heart and then identify the coronary vessels, open the four chambers and observe the intra-cardiac structures. Next, we remove the atria from the ventricles and examine the relation between the valves and the chambers. Our guide is useful for learning the three-dimensional gross anatomy which is fundamental to understanding the normal function and disease of the heart.

: Chagas disease is a neglected tropical disease caused by infection with the parasite . Benznidazole and nifurtimox are the only approved drugs for treating this condition, but their low aqueous solubility may lead to erratic bioavailability. This work aimed for the first time to formulate tablets of nifurtimox by hot melt extrusion coupled with 3D printing as a strategy to increase drug dissolution and the production of tablets with dosage on demand.

Purpose: There is no established method for visualizing the three-dimensional (3D) structure of the aqueous humor outflow tract. This study attempted to visualize the 3D structures of porcine and human ocular tissues, particularly the aqueous humor outflow tract using a transparency reagent composed of 2, 2-thiodiethanol.

Purpose: Digital 3D exoscopes are promising tools for microneurosurgery. The results of exoscope-assisted resection of intracranial meningiomas have only been addressed in few case reports. We retrospectively compared the results of exoscope and microscope-assisted surgery of falx and parasagittal meningiomas.

Urban overheating significantly affects thermal comfort and livability, making it essential to understand the relationship between urban form and land surface temperature (LST). While the horizontal dimensions of urban form have been widely studied, the vertical structures and their impact on LST remain underexplored. This study investigates the influence of three-dimensional urban form characteristics on LST, using ECOSTRESS sensor data and four machine learning models.

ConspectusProtein higher-order structure (HOS) is key to biological function because the mechanisms of protein machinery are encoded in protein three-dimensional structures. Mass spectrometry (MS)-based protein footprinting is advancing protein structure characterization by mapping solvent-accessible regions of proteins and changes in H-bonding, thereby providing higher order structural information. Footprinting provides insights into protein dynamics, conformational changes, and interactions, and when conducted in a differential way, can readily reveal those regions that undergo conformational change in response to perturbations such as ligand binding, mutation, thermal stress, or aggregation.
