OBJECTIVES To test the self-determination model of health-related behavior by examining whether the degree to which adolescents experience an appeal to not smoke as autonomy supportive would affect their autonomous motivation for not smoking and, in turn, their behavior of either refraining from smoking or smoking less, and to validate the measures of perceived autonomy support and autonomous m...

A retrospective case-control study was conducted to determine why some infants born full-term without obstetric intervention to hepatitis B e antigen (HBeAg)-seropositive mothers become infected by hepatitis B virus (HBV) despite having received passive-active immunoprophylaxis. Cases and controls comprised 12 hepatitis B surface antigen (HBsAg)-seropositive infants and 22 HBsAg-seronegative in...

BACKGROUND The objective was to assess the use of physician-prescribed special diets, food preferences, and daily and occasional drug use by elderly participants in a Title III-C Nutrition Program. METHODS Data were collected by nonrandom interviews of congregate and meals-on-wheels clients. Chi-square was used to assess whether food and drug behaviors were related to six population variables...

Introduction Nephropathic cystinosis is a rare autosomal recessive disorder caused by a mutation in the CTNS gene, which encodes for cystinosin. It is characterized by the lysosomal accumulation of cystine, which leads to the formation of cystine crystals within various organs, including kidneys, brain, cornea, intestine and bone marrow. The exact role of intralysosomal cystine crystals accumul...

Nominalizations are expressions that are particularly challenging philosophically in that they help form singular terms that seem to refer to abstract or derived objects often considered controversial. The three standard views about the semantics of nominalizations are [1] that they map mere meanings onto objects, [2] that they refer to implicit arguments, and [3] that they introduce new object...

Objectives This study applied self-determination theory (SDT) to investigate the relationship between students' autonomous motivation and tutors' autonomy support in medical students' academic achievement. Methods This was a cross-sectional study. Out of 204 students in a fundamental medical science course, 199 participated in the study. Data was collected using two questionnaires: the Learni...

The aim of this study was to determine whether the changes in myocardial activation pattern resulting from acute stretching during ventricular fibrillation can be counteracted by administering a compound that blocks receptors sensitive to stretch. The study involved 16 isolated rabbit hearts, in which refractoriness and activation frequency during ventricular fibrillation were measured before, ...

UNLABELLED Our purpose was to evaluate changes in cadaveric donor factors between 1993 and 2004 and their impact on the short- and long-term outcomes of renal transplants in a single center. PATIENTS AND METHODS Cadaveric renal transplants performed in our unit between 1993 and 2004 were divided in two groups of identical length: A (n = 455; 1993-1998) and B (n = 465; 1999-2004). Major differ...

BACKGROUND Sinus mucosa abnormalities on image studies, which is the major diagnostic measure for sinusitis, were investigated in patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT). METHODS A retrospective review of the MRIs for patients with NPC was conducted. Sinus mucosa abnormalities were staged by the Lund-Mackay system. RESULTS A total of 94 pat...

This study prospectively examined the incidence and severity of large joint contractures after burn injury and determined predictors of contracture development. Data were collected prospectively from 1993 to 2002 for consecutive adult burn survivors admitted to a regional burn center. Demographic and medical data were collected on each subject. The primary outcome measures included the presence...
