Resistance of tumor cells to retinoic acid (RA), a promising therapeutic agent, is the major factor limiting the use of RA in clinical practice. The mechanisms of resistance to RA are still poorly understood. Cellular Retinoic Acid Binding Proteins, CRABP1 and CRABP2, are essential mediators of RA signaling, but role of the two CRABP homologs in regulating cellular sensitivity to RA has not been well studied.

Clinicians often lack time, incentives, and opportunities to pause and fully consider the perspective of older adults, especially those with mental illness. As a result, clinicians might infantilize older adults and pathologize or dismiss their preferences, values, and capacity for growth.

Since EVs have been found in almost all body fluids, there are currently active attempts for their application in liquid diagnostics. Blood is the most commonly used source of EVs for the screening of cancer markers, although the percentage of tumor-derived EVs in the blood is extremely low.

Constant expression of the viral oncoproteins, E6 and E7, is required for maintenance of the malignant phenotype of tumor cells. The exact mechanism of regulation of viral oncogenes expression in tumor cells is not fully elucidated.

We sought to address this by implementing an early clinical experience service learning program for medical students in the initial years of their medical education.
Methods: Medical students at Stony Brook University initiated, designed, and facilitated the volunteer program, which provides students a framework to learn magic therapy and engage with pediatric patients.
Objectives: The purpose of this study was to compare the biomechanical attributes of patella fracture fixation with either anterior plating utilizing two parallel, longitudinal 2.0 mm plates technique versus a cannulated screw tension band technique.
Methods: Five matched pairs (ten specimens) of fresh frozen cadavers were utilized.
Objectives: Hospitalization generates increased psychological discomfort for children and their caregivers. This anxiety can affect the patient-caretaker response to the health care team and the course of treatment. We aim to evaluate the impacts of a magic therapy program, organized and facilitated by medical students, on alleviating pediatric inpatient and caregiver anxiety.

Specimens from underwater archaeological excavations have rarely been analysed by Raman spectroscopy probably due to the problems associated with the presence of water and the use of alternative techniques. The discovery of the remains of the Royal Navy warship HMS Swift off the coast of Patagonia, South America, which was wrecked in 1770 while undertaking a survey from its base in the Falkland/Malvinas Islands, has afforded the opportunity for a first-pass Raman spectroscopic study of the contents of several glass jars from a wooden chest, some of which had suffered deterioration of their contents owing to leakage through their stoppers. From the Raman spectroscopic data, it was possible to identify organic compounds such as anthraquinone and copal resin, which were empirically used as materia medica in the eighteenth century to treat shipboard diseases; it seems very likely, therefore, that the wooden chest belonged to the barber-surgeon on the ship.

We compared affective responses to dyspnea 1) in COPD patients vs. healthy volunteers (HV) undergoing the same laboratory stimulus; 2) in COPD during laboratory dyspnea vs.

Design And Setting: Multivariable regression analysis of 485 cases in which tribunals found doctors guilty of professional misconduct. The cases came from four Australian states (New South Wales, Victoria, Queensland and Western Australia) and New Zealand and were decided over a 10-year period (1 January 2000 - 30 September 2009).
Objective: This pilot study examined whether methylphenidate (MPH) was effective in enhancing cognitive performance and attention for children with sickle cell disease (SCD) with cerebrovascular complications who evidence attention problems.
Methods: In this multisite, pilot study, we evaluated 2 separate double-blind controlled clinical trials, including a laboratory trial of the short-term efficacy of MPH, with the second study a 3-week home/school crossover trial evaluating the efficacy of MPH. The laboratory trial included 14 participants between the age of 7 and 16 years.
Objectives: To describe professional discipline cases in Australia and New Zealand in which doctors were found guilty of professional misconduct, and to develop a typology for describing the misconduct.
Design And Setting: A retrospective analysis of disciplinary cases adjudicated in five jurisdictions (New South Wales, Victoria, Queensland, Western Australia and New Zealand) in 2000-2009.
Main Outcome Measures: Characteristics of the cases (setting, misconduct type, patient outcomes, disciplinary measure imposed), characteristics of the doctors involved (sex, specialty, years since qualification) and population-level case rates (by doctor characteristics).
Results of experimental and clinical evaluation of the method of nonspecific hemosorption obtained in the Laboratory of Clinical Immunology and Republican Centre for Application of Extracorporeal Therapies, Research Institute of Physical and Clinical Medicine, since 1985 are presented. Analysis of these and literature data on the efficiency of hemosorption in non-toxicological practice allows for the conclusion of socio-medical and economic feasibility of more extensive application of the method.

The purpose of this study is to describe a new dynamic external fixator (EF) to be applied after knee dislocation, in combination with posterior cruciate ligament (PCL) reconstruction. This approach permits an immediate postoperative mobilization of the joint, with the possibility to perform a delayed ACL reconstruction and eventually reducing the complication rate related to multiple ligament surgery.

In the current study we sought to confirm these findings by examining the OBs of adult zebrafish for choline acetyltransferase (ChAT) immunoreactivity. We observed a diffuse network of varicose ChAT-positive fibers associated with the nervus terminalis ganglion innervating the mitral cell/glomerular layer (MC/GL).

A total of 21 residents in the unsubsidized group (32%) and 24 residents in the subsidized group (96%) owned a PDA. Medical residents who were provided with PDAs perceived them to be less useful than residents who were not provided with them.
