Tissue-resident macrophages specifically express Lactotransferrin and Vegfc during ear pinna regeneration in spiny mice.

The details of how macrophages control different healing trajectories (regeneration vs. scar formation) remain poorly defined. Spiny mice (Acomys spp.

Choosing an appropriate size valve for transcatheter pulmonary valve implantation in a native right ventricle outflow tract.

Introduction: Transcatheter pulmonary valve implantation has been an effective treatment for dysfuntional right ventricular tract outflow tract (RVOT). Defining a landing zone before the intervention is crucial in patients with native RVOT. Improper sizing and undefined landing zone will lead to embolization.

Reliability, validity, and responsiveness of the lower extremity measure for patients with a hip fracture.

Background: The purpose of this study was to determine whether currently published outcome measures of physical function would be suitable for use for older adults with a hip fracture. The measures that were considered were the Musculoskeletal Function Assessment (MFA) Instrument, the Older Americans' Resources and Services (OARS) Multidimensional Functional Assessment Questionnaire physical function subscale, the Toronto Extremity Salvage Score (TESS), and the Short Form-36 (SF-36). Following suggestions by an expert panel and patient interviews, the MFA was not tested further.

Antianginal efficacy and safety of controlled-delivery diltiazem QD versus an equivalent dose of immediate-release diltiazem TID.

Controlled-delivery once-daily diltiazem (qd), 180 mg and 360 mg, was assessed in two multicenter, randomized, double-blind, placebo-controlled trials using a 3 x 3 Latin square design. Both studies compared the controlled-delivery dosage form to the same total daily dose of immediate-release diltiazem administered three times daily (tid) and to placebo. The primary measure of efficacy was the time to termination of the exercise tolerance test (ETT) at 2, 8, and 24 hours after the morning dose.

Diltiazem pharmacokinetics in elderly volunteers after single and multiple doses.

In young healthy volunteers diltiazem does not have linear kinetics between single and multiple doses. Elimination half-life increases and gives AUC's and Cmax higher than those predicted from single dose data. Kinetics of diltiazem were assessed in 16 healthy elderly after a single 60 mg dose and in 24 healthy elderly after 60 mg every 8 h for 7 days.

Early nonhemorrhagic cardiac tamponade complicating acute myocardial infarction: a case report and review of the literature.

Pericarditis and small pericardial effusions frequently occur following acute myocardial infarction (AMI). A case is reported in which nonhemorrhagic cardiac tamponade complicated AMI within three days of the acute event. In such cases the placement of a pericardial drainage catheter may obviate the need for repeated pericardiocentesis.

Two-dimensional echocardiographic detection of left pulmonary artery aneurysm following Potts' anastomosis.

The two-dimensional echocardiographic detection of left pulmonary artery aneurysm following a Pott's anastomosis in a patient with tetralogy of Fallot is described. The diagnosis was confirmed at angiography and surgery.

Pharmacokinetic and pharmacodynamic studies with prazosin in chronic heart failure.

The correlation between the plasma concentration of prazosin and the effects on supine and standing systemic blood pressure and heart rate was examined at 1/2, 1, 2, 4, and 8 hr after single oral doses of 0.5, 1, 2, and 4 mg in 8 patients with severe refractory heart failure due to coronary heart disease. Despite wide between-patient and within-patient variation in the plasma concentration, the grouped results showed a significant linear relationship between dose, peak concentration, and area under the time-concentration curve.
