OBJECTIVE To compare the clinical features of primary vs secondary retinal vasoproliferative tumors (VPTs). METHODS Retrospective case series of 334 tumors in 295 eyes of 275 patients. RESULTS Of 275 patients with VPT, 41% (n = 113) were male and 59% (n = 162) were female, with a mean age of 44 years at presentation. Primary VPT occurred in 80% (n = 219) and secondary VPT, in 20% (n = 56) o...

Sedentary behavior is associated with an attenuated thermogenic response to beta-adrenergic receptor (beta-AR) stimulation, an important regulator of energy expenditure (EE) in humans. Chronic stimulation of beta-ARs, via heightened activity of the sympathoadrenal system, leads to diminished beta-AR function. We have investigated the hypothesis that the thermogenic response of sedentary adults ...

conclusions both l-prp and l-prf could be used to effectively promote the healing of articular cartilage defects of the knee. results mean macroscopic scores of the treated defects were higher than the controls at all sampling times with significant differences (p < 0.05) observed between l-prf treated and control defects (10.13 vs. 8.37) and l-prp treated and control defects (10 vs. 8.5) at 4 ...

Newborn piglets were used to study body protein preservation because it is critical to the survival of premature infants. Quantitative estimates of endogenous fuel use were obtained from 12 to 72 h of age in male piglets. Of the 40 piglets used (1300 +/- 205 g, mean +/- SD), 16 served as a 12-h-old body composition reference (R), 16 were starved (S) and received water only, and 8 received suppl...

The therapeutic efficacy of the combination of cyproheptadine and bromocriptine was studied in 15 patients with active acromegaly showing incomplete GH suppression in response to bromocriptine therapy alone. The mean basal plasma GH was 31.3±5.5 µg/L, and it decreased to 19.0±3.9 µg/L during the single bromocriptine therapy (10-20 mg for 2 to 21 months). When cyproheptadine (12 to 16 mg for 8 t...

Aim To investigate new bone (NB) formation by using bone-block substitute materials with/without recombinant human morphogenetic protein-2 (rhBMP-2). Materials and Methods Three synthetic [biphasic calcium phosphate (BCP); nanostructured hydroxyapatite (NH); 3D-printed tricalcium phosphate/hydroxyapatite (3DP)] one xenogeneic deproteinized bovine mineral (DBBM) block were affixed to rabbit calv...
