White Capsule: A Comprehensive Overview
Biodegradable Double Emulsion Capsules from Hen Egg White
Formation and Stability
Recent research has demonstrated the potential of using hen egg white proteins to create biodegradable double emulsion capsules through a process involving directed self-assembly at oil-water interfaces and acoustic denaturation. The formation of these capsules is highly dependent on the pH of the aqueous phase. At a pH of 5.5, capsules form easily, whereas at a pH of 8.5, formation is more challenging and occurs only at high concentrations and in low quantities. This difference in stability is attributed to competitive stabilization forces at the oil-water interface, which vary with pH levels.
Biodegradability
These capsules are biodegradable and can be completely digested by trypsin, leaving behind small protein aggregates. This property makes them suitable for various applications where biodegradability is essential.
Color-Tunable White-Light-Emitting Capsules
Fabrication and Applications
Innovative methodologies have been developed to create color-tunable white-light-emitting materials using liquid-filled capsules and thermally responsive dyes. This approach allows for the direct transfer of luminescent properties from solution to solid state, facilitating the rational design of miniaturized white-light-emitting materials. These materials are particularly useful in artificial lighting, sensing, and imaging applications.
Color Tunability
By incorporating thermally responsive chromophores, these capsules offer ample modulation of emitted color and enable precise control over white light emission at desired temperatures and excitation wavelengths.
Internal Capsule White-Matter Infarcts and Insomnia
Motor Deficits in Rats
A new model of focal white-matter infarction in the internal capsule of rats has been developed to mimic the lasting neurologic deficits observed in stroke patients. This model uses endothelin-1 to induce highly focal ischemic infarcts, resulting in severe axonal and myelin loss. Rats injected with endothelin-1 at specific posterior locations exhibited robust and persistent pure-motor deficits, making this model suitable for studying neurologic recovery and rehabilitation after white-matter injury.
Insomnia and White Matter Microstructure
Studies have consistently shown altered white matter microstructure in the anterior limb of the internal capsule in individuals with insomnia disorder. Lower fractional anisotropy (FA) values in this region have been associated with insomnia severity, suggesting that the internal capsule plays a role in the neural mechanisms underlying insomnia.
Chemical Analysis of Controlled Substance Analogues
Identification and Classification
In a notable case, four capsules containing white powders were analyzed and found to contain 4-methylmethcathinone, 2-fluoromethamphetamine, alpha-phthalimidopropiophenone, and N-ethylcathinone. These substances were not listed within South Australian controlled substance regulations at the time. The study provided detailed chemical analysis and discussed the implications of classifying these chemicals as controlled substance analogues.
White Blood Cell Classification Using Capsule Networks
Deep Learning Approach
Capsule networks, a new deep learning method, have been successfully used to classify white blood cells (WBCs) into five categories using a small dataset. This approach overcame the limitations of traditional machine learning methods, which require extensive pre-processing and large datasets. Capsule networks achieved a high accuracy of 96.86% on test data, outperforming other deep learning models like convolutional neural networks (CNN) and transfer learning (TL) models.
Colon Capsule Endoscopy
Clinical Applications
Second-generation colon capsule endoscopy (CCE2) has been approved for use in patients with incomplete colonoscopies and those unwilling to undergo conventional colonoscopies. CCE2 has shown significant improvements in diagnostic yield and is particularly beneficial for assessing mucosal inflammation in patients with ulcerative colitis. Comparative studies have highlighted its potential as a cost-effective clinical service for colorectal cancer screening.
Smartphone-Based Multimodal Tethered Capsule Endoscopy
Low-Cost Imaging Solution
A smartphone-based, low-cost, reusable tethered capsule endoscopic platform has been developed for white-light, narrow-band, and fluorescence/autofluorescence imaging of the esophagus. This device, costing approximately 12-42 euros depending on the imaging mode, offers a viable solution for esophageal imaging in underprivileged areas. It has been tested successfully in ex-vivo studies, demonstrating its efficacy and potential for widespread use.
Gentian Violet for Anterior Capsule Staining
Visualization Technique
Gentian violet solutions at concentrations of 0.01% and 0.001% have been used to stain the anterior capsule during continuous curvilinear capsulorhexis (CCC) in human eyes with white mature cataract. This technique improved visualization of the anterior capsule and had no significant toxic effects, although mild corneal edema and inflammatory reactions were observed postoperatively.
Conclusion
The research on white capsules spans a diverse range of applications, from biodegradable emulsion capsules and color-tunable light-emitting materials to medical imaging and drug analysis. These studies highlight the innovative approaches and significant advancements in the field, offering promising solutions for various scientific and clinical challenges.
