Article Abstract
Background: Pneumatic injections of non-cross-linked hyaluronic acid are effective in skin rejuvenation, however, the associated biophysical parameters and appearance have not been evaluated.
Objectives: To determine the changes in skin biophysical parameters after facial pneumatic injections of non-cross-linked hyaluronic acid.
Patients And Methods: Twenty-eight healthy female volunteers received pneumatic injections of non-cross-linked hyaluronic acid into the face for consecutive 5 weeks. Skin biophysical parameter assessment and clinical evaluation were performed using the CK Multi-Probe Adapter and Visia system. Five of the volunteers also underwent retroauricular skin biopsy before and after the last treatment. The skin tissues were all stained with Masson-trichrome, Verhoeff-van Gieson stain, and hematoxylin-eosin to evaluate the changes in collagen, elastic fibers, and the epidermis, before and after the last treatment.
Results: Transepidermal water loss was significantly lower in week 4 (18.46 ± 4.70 g/h/m) than at the baseline (22.03 ± 7.15 g/h/m, p < 0.05). Skin texture was better in week 4 (599.29 ± 354.32) than at the baseline (668.43 ± 342.55, p < 0.05). Skin pores also improved significantly at week 4 (934.07 ± 458.78) compared to the baseline (1024.57 ± 415.31, p < 0.05). Skin wrinkles were improved at the 3-month follow-up (29.29 ± 11.11) compared to the baseline (35.83 ± 16.05, p < 0.05).
Conclusion: Pneumatic injections of non-cross-linked hyaluronic acid improved skin TEWL, texture, pores, and wrinkles.

Stereotactic neurointervention is a common procedure for biopsy, injection, ablation, and implantation of electrodes for deep brain stimulation. Guided by preoperative imaging, conventional approaches are mostly performed manually, lacking operation stability and interactive feedback. The intraoperative magnetic resonance imaging (MRI) guidance enables both structural and functional assessment during operation, permitting interactive adaptation to tissue deformation and avoidance of critical anatomical regions.

Achalasia is an esophageal motility disorder with symptoms like regurgitation, dysphagia, anorexia, and chronic cough. Effective treatments include pneumatic dilatation and myotomy. This study evaluated the combined use of botulinum toxin (Botox) injection and esophageal balloon dilation versus balloon dilation alone, analyzing recovery rates for gastrointestinal and non-gastrointestinal symptoms.

Background: To assess hemolysis potential, blood pump developers frequently perform in vitro testing in accordance with the ASTM F1841 standard. However, options in test parameters such as blood species, anticoagulant, and blood collection and preparation methods can lead to inconsistent hemolysis results.
Methods: To improve in vitro hemolysis test sensitivity and characterize the impact of species and hematocrit (HCT) on flow-induced hemolysis, a pressure-driven, single-pass micro-nozzle test system with short blood exposure times was developed.
To our knowledge, a novel experimental method is proposed to remotely measure the droplet concentration in a water spray using a short-range elastic backscatter lidar. A specific calibration technique is proposed to determine the lidar radiometric constant, enabling the conversion of lidar signals into attenuated backscatter signals and, ultimately, into aerosol properties, including average volume concentration. To our knowledge, a new formulation for the lidar constant is proposed, using the total spray transmittance and the particle size distribution of the water droplets, measured using the established laser diffraction technique.
