BACKGROUND Androgenetic alopecia is a common condition, with severe attendant psychosocial implications, and for which it is difficult to obtain a satisfactory degree of clinical improvement. OBJECTIVE To explore the possible clinical benefit of injecting platelet-derived growth factors into the scalp of patients using a specific autologous blood(More)
Nine clinically healthy men, 41-47 yr of age, served as subjects in a 24-hr study conducted at the Edward Hines Jr Veterans Administration Hospital in the Chicago area in May 1988. Physiologic measurements, and blood and urine samples were collected at 3-hr intervals over a single 24-hr period beginning at 1900. The number of variables measured or(More)
In prior studies, we have shown that the antikaliuretic drugs, triamterene and amiloride, through a direct cardiac effect reduce the loss of cardiac potassium induced by the administration of digitalis. Since loss of myocardial potassium is thought to underlie digitalis arrhythmias, this study was performed to determine whether triamterene and amiloride(More)
BACKGROUND Hyaluronic acid and onabotulinumtoxinA combination therapy has been shown to have greater clinical effectiveness than hyaluronic acid alone for glabellar furrowing, but this is not well documented for melomental fold rhytides. OBJECTIVE To compare the efficacy of intradermal cross-linked hyaluronic acid (HA) and onabotulinumtoxinA combination(More)
At 3-hr intervals over a 24-hr span, 36 systemic, serologic and urinary variables were examined in 7 men in their mid 20's in the Spring of 1969, and again in the same 7 men in the Spring of 1979 under a similar chronobiologic protocol, using the same chemical and numerical analytical procedures. The variables examined for rhythms by cosinor were: vital(More)
BACKGROUND Poor growth has been reported after densely packed megasessions. These reports have been fairly consistent. Despite these statements, excellent growth is seen in the majority of their cases. The author's have theorized that iatrogenic trauma from inappropriate graft handling is one etiology that substantially contributes to poor growth. (More)
Long-acting natriuretic peptide (LANP), vessel dilator (VSDL), and atrial natriuretic factor (ANF) consisting of amino acids (aa) 1 to 30, 31 to 67, and 99 to 126, respectively, of the 126-aa ANF prohormone circulate in humans. Among the biologic properties of these peptides is the ability of ANF to decrease intracellular calcium concentrations. To(More)
Long-acting natriuretic peptide (LANP), vessel dilator (VSDL), and atrial natriuretic factor (ANF) consisting of amino acids 1-30, 31-67, and 99-126 of the 126 amino acid ANF prohormone, respectively, circulate in humans and have potent natriuretic properties. To determine whether these peptides have a direct relationship to serum Na and/or Cl, we examined(More)
Circadian variation in the circulating concentrations of the N-terminal and C-terminal portions of the atrial natriuretic factor prohormone (pro ANF) was evaluated in 8 men, ages 41-47, who have been followed for 19 years with respect to circadian variation in physiological variables including blood pressure and clinical chemistries. The N-terminus of the(More)
STUDY DESIGN To determine whether the normovolemic hemodilution (NH) technique would limit postoperative homologous blood transfusion requirements in 68 patients having multilevel lumbar laminectomies (3-6 levels) with predominant 1- or 2-level instrumented fusions. OBJECTIVE In this setting, to define postoperative homologous blood transfusion(More)
