A hypoxia-responsive TRAF6-ATM-H2AX signalling axis promotes HIF1α activation, tumorigenesis and metastasis.

The understanding of how hypoxia stabilizes and activates HIF1α in the nucleus with related oncogenic signals could revolutionize targeted therapy for cancers. Here, we find that histone H2AX displays oncogenic activity by serving as a crucial regulator of HIF1α signalling. H2AX interacts with HIF1α to prevent its degradation and nuclear export in order to allow successful VHL-independent HIF1α transcriptional activation.

PROBING IIb3: LIGAND INTERACTIONS BY DYNAMIC FORCE SPECTROSCOPY AND SURFACE PLASMON RESONANCE.

The interaction between platelet integrin IIb3 and fibrin(ogen) plays a key role in blood clot formation and stability. Integrin antagonists, a class of pharmaceuticals used to prevent and treat cardiovascular disease, are designed to competitively interfere with this process. However, the energetics of the integrin-drug binding are not fully understood, potentially hampering further development of this class of pharmaceuticals.

Primary cardiac lymphoma diagnosed by multiphase-gated cardiac CT and CT-guided percutaneous trans-sternal biopsy.

We present a case of a primary cardiac B-cell lymphoma where a multiphase-gated cardiac CT exam helped to successfully guide trans-sternal needle biopsy to establish a tissue diagnosis.

Hyperbaric oxygen for stroke treatment.

This is an editorial for the inauguration of the Medical Gas Research and addresses a particular issue of using hyperbaric oxygen for stroke treatment.

Medical students' attitudes toward underserved patients: a longitudinal comparison of problem-based and traditional medical curricula.

Medical education has been shown to negatively influence student attitudes toward certain types of patient populations. Past research does not inform current educational practice because today's medical school environment is different from when most of the published research was conducted. There are more female students, curricular innovations such as problem-based learning have changed the framework for educational delivery, and longitudinal studies, which could inform when interventions may be needed, are uncommon.

Severity of emotional and behavioral problems among poor and typical readers.

The purpose of this study was to examine the severity of behavioral and emotional problems among adolescents with poor and typical single word reading ability (N = 188) recruited from public schools and followed for a median of 2.4 years. Youth and parents were repeatedly assessed to obtain information regarding the severity and course of symptoms (depression, anxiety, somatic complaints.

Ultrasound of nerve and muscle.

Over the last two decades, ultrasound has developed into a useful technology for the evaluation of diseases of nerve and muscle. Since it is currently not used at by the majority of clinicians involved in diagnosis or care of patients with neuromuscular disorders, this review briefly describes the technical aspects of ultrasound and its physical principles. It relates normal muscle anatomy and movement to ultrasound images in the axial and sagittal planes and follows with a discussion of ultrasound findings in chronic muscle disease.

The Lown Symposium: The Field of DNA Minor Groove Binders Celebrates the Career of Professor J. William Lown.

Abstract A symposium co-organized by Professor William H. Gmeiner of Wake Forest University School of Medicine and Professor Moses Lee of Furman University was held March 30 and 31, 2001 on the campus of Wake Forest University School of Medicine. The Symposium was attended by many distinguished colleagues, friends and co-workers of Professor Lown who share his enthusiasm and passion for targeting DNA for treatment of human disease.
