Acoustic Radiation Force Optical Coherence Elastography of the Crystalline Lens: Safety.
Transl Vis Sci Technol
December 2024
Department of Biomedical Engineering, University of Houston, Houston, TX, USA.
Purpose: To assess the safety of acoustic radiation force optical coherence elastography in the crystalline lens in situ.
Methods: Acoustic radiation force (ARF) produced by an immersion single-element ultrasound transducer (nominal frequency = 3.5 MHz) was characterized using a needle hydrophone and used for optical coherence elastography (OCE) of the crystalline lens.
Metabolic Characteristics of Sclera in Lens-Induced Myopic Guinea Pigs.
Invest Ophthalmol Vis Sci
November 2024
Shanghai Institute of Infectious Disease and Biosecurity, Zhongshan Hospital, Fudan University, Shanghai, China.
Article Synopsis
- Myopia in guinea pigs was induced using special lenses, and researchers investigated the metabolic changes in the sclera, focusing particularly on amino acid levels.
- Metabolomic analyses revealed significant alterations in metabolic pathways linked to myopia, highlighting reductions in specific amino acids in the affected sclera.
- Supplementing with glycine was found to counteract some effects of myopia, increasing collagen levels, inhibiting eye elongation, and reversing changes in certain proteins associated with this condition.
Intrastromal graft of anterior lens capsule. A substitute for Bowman layer graft transplantation for keratoconus.
PLoS One
November 2024
Escuela Superior de Oftalmologia, Instituto Barraquer de America, Bogota, Colombia.
Article Synopsis
- A study was conducted to assess the effectiveness of using porcine anterior lens capsules as a substitute for Bowman layer grafts in rabbits with keratoconus, due to a shortage of donor corneas.
- The research involved transplanting the lens capsules into the corneal stroma of rabbits and monitoring changes in corneal transparency, thickness, and shape at various time points.
- Results indicated that the transplanted lens capsules preserved corneal transparency and structural integrity without any negative effects, suggesting they could be viable alternatives to Bowman layer grafts in corneal surgeries.
Comparison of Subdural and Intracortical Recordings of Somatosensory Evoked Responses.
Sensors (Basel)
October 2024
Center for Neuroplasticity and Pain, Department of Health Science and Technology, Aalborg University, Selma Lagerløfs Vej 249, 9260 Aalborg, Denmark.
Micro-electrocorticography (µECoG) electrodes have emerged to balance the trade-off between invasiveness and signal quality in brain recordings. However, its large-scale applicability is still hindered by a lack of comparative studies assessing the relationship between ECoG and traditional recording methods such as penetrating electrodes. This study aimed to compare somatosensory evoked potentials (SEPs) through the lenses of a µECoG and an intracortical microelectrode array (MEA).

Nutrients
September 2024
Department of Pharmacy-Drug Sciences, University Aldo Moro-Bari, 70126 Bari, Italy.
Article Synopsis
- Researchers examined lentil seed coats for their health benefits, particularly in managing inflammatory bowel diseases (IBDs).
- They used both traditional and microwave-assisted extraction methods to obtain extracts, finding the microwave method with ethyl acetate the most effective for anti-inflammatory and spasmolytic activity.
- The study concluded that this extract could support intestinal health, indicating its potential as a dietary supplement to help treat intestinal issues.
