purpose: to compare visual outcomes after deep anterior lamellar keratoplasty (dalk) between eyes with and without successful big-bubble formation. methods: in this retrospective comparative study, a total of 290 consecutive eyes from 257 keratoconus-affected patients underwent dalk with the big-bubble technique were enrolled. in cases where the big bubble could not be accomplished, manual stro...

BACKGROUND When acute aortic dissection is complicated with acute myocardial infarction, the diagnosis of dissection can be problematic. In these cases, patients might be treated with primary percutaneous coronary intervention (PCI) and suffer acatastrophic outcome. However, there are few reports or algorithm to facilitate the accurate management of this clinical situation. METHODS We evaluat...

A mechanically sound and compliant biomaterial with superior cell adhesion and remodeling capabilities would be an ideal tissue engineering scaffold. Although processed ex vivo tissues have many of these desired qualities they have seen limited use primarily due to the lack of physical uniformity and tediousness, time consuming preparation methodologies. In this investigation, a novel method fo...

DEEP ANTERIOR LAMELLAR KERATOPLASTY: A NEW MANUAL TECHNIQUE Rama et al report visual outcomes in 288 eyes undergoing deep anterior lamellar keratoplasty with a new manual dissection technique. A deep corneal incision was obtained with a calibrated diamond knife to reach a pre-Descemet plane. At the 2-year postoperative follow-up, the mean logarithm of the minimum angle of resolution best specta...

PURPOSE This study was designed to evaluate the efficacy of a fat clearing technique for accurate nodal staging of rectal cancer patients after preoperative chemoradiotherapy (CRT). METHODS A total of 19 patients with rectal cancer within 10 cm from anal verge were divided into two groups: non-CRT group (n = 10) and CRT group (n = 9). For pathologic assessment, lymph node (LN) harvest was per...

BACKGROUND Ultrasonic scalpel (UC) and monopolar electrocautery (ME) are common tools for soft tissue dissection. However, morphological data on the related tissue alteration are discordant. We developed an automatic device for standardized sample excision and compared quality and depth of morphological changes caused by UC and ME in a pig model. METHODS 100 tissue samples (5 × 3 cm) of the a...

Spinal manipulation usually represents a widely used and effective method for physicians in order to relieve acute patient pain and muscular dysbalance. Although life-threatening complications (e.g. pneumothorax, vertebral artery dissection, stroke) after manual treatment are reported with regard to actual medical literature millions of patients undergo manual treatment to manage thoracolumbar ...

Tetrad analysis is a valuable tool for yeast genetics, but the laborious manual nature of the process has hindered its application on large scales. Barcode Enabled Sequencing of Tetrads (BEST)1 replaces the manual processes of isolating, disrupting and spacing tetrads. BEST isolates tetrads by virtue of a sporulation-specific GFP fusion protein that permits fluorescence-activated cell sorting o...
