Article Abstract
Purpose: This study aimed to evaluate the association between cholecystectomy and colonic bubble formation during colonoscopy, METHODS: A single-center retrospective cohort study was conducted at Staten Island University Hospital. Researchers reviewed 348 colonoscopy reports, comparing patients with (n = 56) and without (n = 292) a history of cholecystectomy. Colonic bubble formation was assessed using a 0-3 scale (0 = no bubbles, 3 = severe bubbles). Secondary endpoints included polyp and adenoma detection, withdrawal and procedure times, bowel preparation quality, and repeat procedures. Statistical analysis included t-tests, Mann-Whitney U tests, and χ tests.
Results: Patients with prior cholecystectomy had significantly higher incidence of severe bubble formation (score 3; 28.6% vs. 12%, p = 0.001), longer withdrawal times (18 ± 8 vs. 15 ± 5 min, p = 0.024), and increased need for repeat colonoscopies (10.7% vs. 2.1%, p = 0.001). No significant differences were found in adenoma detection, polyp detection, or bowel preparation quality between the two groups.
Conclusion: Cholecystectomy is associated with increased colonic bubble formation during colonoscopy, leading to longer withdrawal times and higher rates of repeat procedures. While this study did not find a difference in adenoma detection rates, the impaired visualization caused by bubbles may necessitate tailored bowel preparation strategies for patients with a history of cholecystectomy to optimize colonoscopy effectiveness.

Flow fields (FFs) play multifaceted roles in direct methanol fuel cells (DMFC) by facilitating the transport and distribution of species, removal of products, support to the membrane electrode assembly (MEA), electrical conductivity, water, and thermal management. Therefore, the performance of DMFC is directly related to the pattern and geometry of the FF. DMFCs can generate power density of up to ≈100-300 mW cm; however, their performance is impeded by cathode flooding, CO gas bubbles formation, and mass transfer limitations.

In this study, the effects of operating temperature on pore-scale gas bubble transport in a carbon-based anode porous transport layer (PTL) of a polymer electrolyte membrane (PEM) electrolyzer is revealed using operando X-ray computed tomography (CT). Higher temperature operation (80 °C compared to 40 °C) led to a lower total gas bubble volume fraction in the PTL (0.25 to 0.

A nanosecond pulse transient plasma is employed to initiate and control the exothermic decomposition of ionic liquids, namely, a mixture of hydroxylammonium nitrate (HAN) and 1-ethyl-3-methylimidazolium ethyl sulfate [EMIM]/[EtSO], as well as some noncombustible ionic liquids. Here, the plasma is discharged in a cylindrical geometry with a coaxial center wire electrode. High voltage (20 kV) nanosecond pulses (20 ns) at various frequencies up to 10 kHz produce a plasma discharge in the ionic liquid that initiates its nonthermal decomposition.

The increasing presence of nanoplastics (NPs) and synthetic antioxidants like 3-tert -Butyl-4-hydroxyanisole (3-BHA) in the environment has attracted widespread attention about their combined toxicological effects on human health, particularly on renal function. This study explored to the combined impacts of NPs and 3-BHA at environmentally relevant concentrations on sub-chronic kidney injury in mice. Firstly, our results confirmed that the accumulation of 80 nm NPs in renal tissues, leading to structural abnormalities such as reduced mitochondrial cristae and increased empty bubbles in mice by transmission electron microscope (TEM) analysis.

Closed capsules, such as lipid vesicles, soap bubbles, and emulsion droplets, are ubiquitous throughout biology, engineered matter, and everyday life. Their creation and disintegration are defined by a singularity that separates a topologically distinct extended liquid film from a boundary-free closed shell. Such topology-changing processes are of fundamental interest.
