The pulmonary vasculature plays a pivotal role in the development and progress of chronic lung diseases. Due to limitations of conventional two-dimensional histological methods, the complexity and the detailed anatomy of the lung blood circulation might be overlooked. In this study, we demonstrate the practical use of optical serial block face imaging (SBFI), ex vivo microcomputed tomography (micro-CT), and nondestructive optical tomography for visualization and quantification of the pulmonary circulation's 3D architecture from macro- to micro-structural levels in murine lung samples.

Cryopreservation, the preservation of tissues at subzero temperatures, is a mainstay of brain banking that allows for the storage of brain tissue without the use of chemical fixatives. This is particularly important for molecular studies that are incompatible with tissue fixation. However, brain tissue is vulnerable to various forms of damage during the cryopreservation process, in particular due to the phase transition of water from a liquid to a solid state with the formation of ice crystals, which can disrupt cellular morphology.

Bubble-microplastic (MP) interaction is a significant process that changes the routes of MP circulation in marine environment and thereby determines the risk of MPs, which could be strongly influenced by natural organic matter (NOM) in oceans. However, the quantitative interaction mechanisms between bubbles and MPs under the effect of NOM remain elusive. Herein, bubble-MP interactions in simulated seawater were quantified at nanoscale based on atomic force microscope coupled with the Stokes-Reynold-Young-Laplace model.

Background: The gold standard for crystal arthritis diagnosis relies on the identification of either monosodium urate (MSU) or calcium pyrophosphate (CPP) crystals in synovial fluid. With the goal of enhanced crystal detection, we adapted a standard compensated polarized light microscope (CPLM) with a polarized digital camera and multi-focal depth imaging capabilities to create digital images from synovial fluid mounted on microscope slides. Using this single-shot computational polarized light microscopy (SCPLM) method, we compared rates of crystal detection and raters' preference for image.

Objective: To investigate the physiological characteristics of subspecies (Bti) with double mutations of and genes and to assess the activity of Bti against larvae of under different external factors, so as to provide the theoretical evidence for the use of engineered bacteria of Bti for effective mosquito control.
Methods: wild-type strain Bt-59 and Bt-59 strain with mutation [Bt-59 (Δ)] were cultured in nutrient broth media for 24 hours, and Bt-59 strains with mutation [Bt-59 (Δ)] and double mutations of and [Bt-59 (Δ)] were cultured in nutrient broth media for 48 hours. Then, 5 μL of culture media were transferred to glass sides, and cell morphology and mother cell lysis were observed under an optical microscope.
