PURPOSE Ultrasound activation of phacoemulsification (phaco) tips can create considerable thermal energy that may increase the risk of tissue damage during cataract surgery. The purpose of this study was to define the thermal profiles of three phaco tip designs in simulated surgical conditions. METHODS In this laboratory investigation, sleeved phaco tips (mini-flared Kelman(®) tip with aspira...

OBJECTIVE To verify if mini-implant mobility is affected by the presence of periodontopathogens, frequently associated with peri-implantitis. MATERIALS AND METHODS The surfaces of 31 mini-implants used for skeletal anchorage in orthodontic patients were evaluated. Polymerase chain reaction was used for identification of the presence of DNA from three different periodontopathogens ( P. interme...

By using a binary vector system, we examined the requirements for border sequences in T-DNA transformation of plant genomes. Mini-T plasmids consisting of small replicons with different extents of pTiT37 T-DNA were tested for plant tumor-inducing ability in Agrobacterium tumefaciens strain LBA4404 containing helper plasmid pAL4404 (which encodes virulence genes needed for T-DNA transfer). Assay...

COMPARISON OF HEMILAMINECTOMY AND MINI-HEMILAMINECTOMY IN DOGS WITH THORACOLUMBAR INTERVERTEBRAL DISC EXTRUSION USING COMPUTED TOMOGRAPHY AND MAGNETIC RESONANCE IMAGING: AN ANATOMICAL AND RADIOLOGICAL STUDY Jonathan Huska Co-Advisor: Luis Gaitero University of Guelph, 2012 Co-Advisor: Brigitte Brisson This thesis is an investigation of the access provided to the vertebral canal in dogs by the h...

In this paper I have reduced the US model to a smaller size. This version, called “US mini,” is a good approximation to the overall US model in a number of important respects, although a number of features have been left out. The income side has been substantially reduced; there is no labor sector; and there is no wage-price sector, just a price equation. US mini is thus not a replacement for t...

BACKGROUND AND OBJECTIVE This study compares hospital costs and clinical outcomes for conventional laparoscopic, single-port, and mini-laparoscopic cholecystectomy from US hospitals. METHODS Eligible patients were aged ≥18 years and undergoing laparoscopic cholecystectomy with records in the Premier Hospital Database from 2009 through the second quarter of 2010. Patients were categorized into...

the aim of this study was to examine factors affecting adoption of mini-tuber seed potato. survey research design was used in this study. a sample of 100 potato growers who were informed about mini-tuber was selected and divided into adopter and non-adopter groups. questionnaire was used as the instrument for data collection and was validated by a panel of experts. a pilot study was conducted f...

Objective: This study was designed to assess the deformation and fracture of orthodontic miniimplants of different commercial brands by submitting them to loads perpendicularly applied along their lengths. Materials and Methods: A total of 75 mini-implants were divided into five groups (n=15): M (Mondeal, Tuttlingen, Germany), N (Neodent, Curitiba, Brasil), I (INP, São Paulo, Brazil), S (SIN, S...

OBJECTIVE Blood biochemistry, ascites tests, and imaging examinations have low sensitivities in abdominal neoplasm diagnoses. In addition, exploratory laparotomy is not suitable for final stage patients. Mini-laparoscopy has recently emerged as a new diagnostic technology for abdominal disease. The aim of this research was to evaluate the value of mini-laparoscopy in diagnosing abdominal neopla...

INTRODUCTION Orthodontic mini-implants are a potential source of metallic ions to the human body because of the corrosion of titanium (Ti) alloy in body fluids. The purpose of this study was to gauge the concentration of Ti, aluminum (Al), and vanadium (V), as a function of time, in the kidneys, livers, and lungs of rabbits that had Ti-6Al-4V alloy orthodontic mini-implants placed in their tibi...
