Comparison of Visual and Refractive Outcomes of Keratorefractive Lenticule Extraction for Compound Myopic Astigmatism Between VisuMax and VISUMAX 800.

Purpose: To evaluate the visual outcomes of keratorefractive lenticule extraction using a new version of a femtosecond laser platform with semi-automated cyclotorsion compensation in comparison to the previous generation without cyclotorsion control.

Methods: This was an ambispective study of consecutive eyes treated by SMILE with the VisuMax and VISUMAX 800 femtosecond lasers at the Uma Eye clinic, Chennai, India between June 2022 and July 2023. Inclusion criteria were myopia up to -10 D and astigmatism between 1.

Genome-Scale Metabolic Model Reconstruction and Investigation into the Fluxome of the Fast-Growing Cyanobacterium sp. PCC 11901.

The ability to convert atmospheric CO and light into biomass and value-added chemicals makes cyanobacteria a promising resource microbial host for biotechnological applications. A newly discovered fastest-growing cyanobacterial strain, sp. PCC 11901, has been reported to have the highest biomass accumulation rate, making it a preferred target host for producing renewable fuels, value-added biochemicals, and natural products.

Biomanufacturing of value-added chemicals from lignin.

Lignin valorization faces persistent biomanufacturing challenges due to the heterogeneous and toxic carbon substrates derived from lignin depolymerization. To address the heterogeneous nature of aromatic feedstocks, plant cell wall engineering and 'lignin first' pretreatment methods have recently emerged. Next, to convert the resulting aromatic substrates into value-added chemicals, diverse microbial host systems also continue to be developed.

Levator Labii Superioris Alaeque Nasi Targeted Botulinum Toxin Injection for Treatment of Perinasal Facial Discomfort and Snarling.

Botulinum toxin has been increasingly studied and used for varying conditions, most notably, cosmetics. However, it has been shown that botulinum toxin demonstrates a high efficacy in treating spasticity disorders throughout the body, including the face. Facial spasms vary in pathophysiology, region, and severity.

Assessing the surgical competency of novice surgeons by using a three-dimensional heads-up display microscope.

Purpose: To evaluate the surgical performance of novice surgeons operating on a three-dimensional (3D) heads-up display system compared to those using a traditional microscope (TM).

Methods: Prospective study design in a private practice setting. Twenty novice surgeons with similar experiences in cataract surgery were selected.
