The efficiency of venturi versus peristaltic based phacoemulsification in femtosecond laser cataract surgery: Venturi vs peristaltic based phacoemulsification for cataract.

Purpose: To compare the efficiency of peristaltic vs venturi vacuum platforms when applied to the femtosecond treated cataract.

Setting: Outpatient Eye Center, Mercy Health System, Springfield, MO, USA.

Design: This is a prospective randomized controlled trial of 111 patients with moderate nuclear sclerosis scheduled for bilateral routine laser cataract surgery (clinicaltrials.

Trees First Inhibit Then Promote Litter Decomposition in the Subarctic.

Trees affect organic matter decomposition through allocation of recently fixed carbon belowground, but the magnitude and direction of this effect may depend on substrate type and decomposition stage. Here, we followed mass loss, chemical composition and fungal colonisation of leaf and root litters incubated in mountain birch forests over 4 years, in plots where belowground carbon allocation was severed by tree girdling or in control plots. Initially, girdling stimulated leaf and root litter mass loss by 12% and 22%, respectively, suggesting competitive release of saprotrophic decomposition when tree-mediated competition by ectomycorrhizal fungi was eliminated (Gadgil effect).

TiCT MXene Thin Films and Intercalated Species Characterized by IR-to-UV Broadband Ellipsometry.

MXenes are two-dimensional (2D) materials with versatile applications in optoelectronics, batteries, and catalysis. To unlock their full potential, it is crucial to characterize MXene interfaces and intercalated species in more detail than is currently possible with conventional optical spectroscopies. Here, we combine ultra-broadband ellipsometry and transmission spectroscopy from the mid-infrared (IR) to the deep-ultraviolet (UV) to probe quantitatively the composition, structure, transport, and optical properties of spray-coated TiCT MXene thin films with varying material properties.

Short- and Medium-Term Outcomes Assessment of Urethral Prostatic Lift (UroLift) as a Minimally Invasive Treatment for Benign Prostatic Hyperplasia in a Tertiary Care Centre.

Introduction And Aim:  Benign prostatic hyperplasia (BPH) is the enlargement and overgrowth of the prostate leading to the compression of the urethra and resulting in obstruction to the outflow of urine. Prostatic urethral lift (UroLift) is a budding minimally invasive technique that utilises mechanical manipulation of the prostate tissue so that the urethra is free from compression, thereby creating a channel for the outflow of urine. The aim of the audit was to assess the short- to medium-term outcomes in our centre in terms of improvement in symptoms, quality of life (QoL) and complication rates.

Indoor carbon monoxide exposures in a retail occupancy.

In a two-story retail mall in the Southeastern United States, employees within Store A (located on the second level) began to feel headaches and general unease and discussed the symptoms among themselves. Approximately 1.5 hr later, an employee called 9-1-1.
