Preference Signaling in the Radiology Residency Match: National Survey of Applicants.

Objective: Two-tiered preference signaling has been implemented in the radiology residency application system to reduce congestion in the setting of high-volume applications. Signals are an indicator of strong interest that an applicant can transmit to a limited number of programs. This study assessed the impact of program signaling on interview invitations, how applicants strategically used signals based on their application's competitiveness, and applicants' attitudes toward the current signaling system.

Use of vitreous phenotype as a key clinical marker to identify Ocular-only Stickler syndrome in a family with Marfan syndrome.

This clinical report describes a family with both Marfan and ocular-only Stickler syndromes. We report 2 cases of ocular-only Stickler syndrome and 2 cases of Marfan syndrome concurrent with ocular-only Stickler syndrome. Type 1 Stickler syndrome and Marfan syndrome share many clinical similarities, and it can be difficult to differentiate them solely based on clinical presentation.

Enhanced cellulose nanofiber mechanical stability through ionic crosslinking and interpretation of adsorption data using machine learning.

Herein we report the fabrication of cationic functionalized cellulose nanofibers (c-CNF) having 0.13 mmol.g ammonium content and its ionic crosslinking via the pad-batch process.

Highly targeted electrochemical disruption of microbes with minimal disruption to pulp cells.

Introduction: Pulpitis results from the infiltration of mixed populations of bacteria which trigger inflammation in the dental pulp, causing significant disruption to these tissues. Clinically, pulpitis frequently leads to devitalization or extraction, as disinfection of the dental pulp while maintaining its vitality is extremely difficult. Here we describe the use of an electrocatalytic titanium dioxide (TiO)-based apparatus adapted from water purification technology, which can efficiently deliver anti-microbial oxidants (e.

Modelling and synthesis of Magnéli Phases in ordered titanium oxide nanotubes with preserved morphology.

The presence of Magnéli phases in titanium oxide nanotubes (NTs) can open up frontiers in many applications owing to their electrical and optical properties. Synthesis of NTs with Magnéli phases have posed a challenge due to the degradation and loss of morphology in NTs upon high-temperature treatments (>600 °C) in a reducing environment. This study reports on the synthesis of anodically formed NTs containing Magnéli phases through a double annealing route: oxygen (O) annealing followed by annealing in 2% hydrogen with a nitrogen balance (2%H-N).

Axillary Artery Injury In Blunt Shoulder Trauma - An Uncommon Association With Proximal Humerus Fracture.

Axillary artery injury along with proximal humerus fracture as a result of blunt trauma is a rare incidence. We present a 65-year-old male with a pulseless cold hand, who had blunt trauma 3 days ago, leading to fracture of proximal end of humerus along with axillary artery injury. Surgical intervention revealed contusion of axillary artery with intravascular thrombosis causing complete occlusion.

Electrochemical Detection of O157:H7 in Water after Electrocatalytic and Ultraviolet Treatments Using a Polyguanine-Labeled Secondary Bead Sensor.

The availability of clean drinking water is a significant problem worldwide. Many technologies exist for purifying drinking water, however, many of these methods require chemicals or use simple methods, such as boiling and filtering, which may or may not be effective in removing waterborne pathogens. Present methods for detecting pathogens in point-of-use (POU) sterilized water are typically time prohibitive or have limited ability differentiating between active and inactive cells.

Removal of lead from aqueous solution using polyacrylonitrile/magnetite nanofibers.

Lead is known for its toxic and non-biodegradable behavior. The consumption of lead-contaminated water is one of the major threat the world is facing nowadays. In this study, polyacrylonitrile (PAN) and magnetite (FeO) composite nanofiber adsorbent was developed for Pb removal in batch mode.

Three-dimensional printing in surgery: a review of current surgical applications.

Background: Three-dimensional printing (3DP) is gaining increasing recognition as a technique that will transform the landscape of surgical practice. It allows for the rapid conversion of anatomic images into physical objects, which are being used across a variety of surgical specialties. It has been unclear which groups are leading the way in coming up with novel ways of using the technology and what specifically the technology is being used for.

Treatment of ureteric calculi--use of Holmium: YAG laser lithotripsy versus pneumatic lithoclast.

Objective: To compare the efficacy of Holmium: YAG laser and pneumatic lithoclast in treating ureteric calculi.

Methods: The study included total of 100 patients divided into two equal groups of laser lithotripsy (LL) and pneumatic lithoclast (PL). Study was conducted between September 2006 and February 2007.

Comparison of holmium: Yag laser and pneumatic lithoclast in percutaneous nephrolithotomy.

Objective: To compare holmium Yag laser with lithoclast in patients with renal stones undergoing percutaneous nephrolithotomy (PCNL).

Methods: A comparative cross sectional study was performed on 60 patients undergoing PCNL. Patients with a 2.

Soft tissue neck symptoms following high-energy road traffic accidents.

Study Design: A single-blinded prospective study was performed into the occurrence and frequency of soft tissue neck symptoms of patients involved in high-energy road traffic accidents.

Objectives: We studied the occurrence of incidental soft tissue neck symptoms in victims of high energy (defined as those severe enough to cause major trauma leading to an injury severity score >16) vehicular collisions causing significant musculoskeletal trauma requiring operative intervention.

Summary Background Data: Whiplash is considered to be a soft tissue injury of the neck sustained by occupants of motor vehicles.

Interactions of "ultra-low" doses of naltrexone and morphine in mature and young male and female rats.

Sex and age influence morphine analgesia in humans and animals. Mature rats show greater morphine analgesia in males than in females. Ultra-low doses of naltrexone enhance morphine analgesia.
