BACKGROUND Despite interest from both radiation oncology residents and program directors, many residency training programs lack a formalized introductory curriculum to orient incoming radiation oncology residents to the specialty. METHODS Using the 6-step model for medical education curriculum development, a structured introductory radiation oncology curriculum (IROC) was created for incoming PGY-2 radiation oncology residents to address foundational concepts including patient simulation, contouring, and plan evaluation. The curriculum was distributed to 55 training programs across the US and Canada at the start of the 2018-2019 and 2019-2020 academic years. Feasibility of curriculum dissemination was assessed via a survey of participating program directors. Curriculum effectiveness was assessed using an anonymous survey of participating residents administered pre-and post-curriculum and consisting of both subjective and objective knowledge-based questions. RESULTS A total of 236 residents participated in IROnd standardize radiation oncology educational initiatives across training programs. Inflammation and activation of the immune system are key molecular and cellular events in the pathogenesis of cardiovascular diseases, including atherosclerosis, hypertension-induced target-organ damage, and abdominal aortic aneurysm. Angiotensin II (Ang-II) is the main effector peptide hormone of the renin-angiotensin system. Beyond its role as a potent vasoconstrictor and regulator of blood pressure and fluid homeostasis, Ang-II is intimately involved in the development of vascular lesions in cardiovascular diseases through the activation of different immune cells. The migration of leukocytes from circulation to the arterial subendothelial space is a crucial immune response in lesion development that is mediated through a sequential and coordinated cascade of leukocyte-endothelial cell adhesive interactions involving an array of cell adhesion molecules present on target leukocytes and endothelial cells and the generation and release of chemoattractants that activate and guide leukocytes to sites of emigration. In this review, we outline the key events of Ang-II participation in the leukocyte recruitment cascade, the underlying mechanisms implicated, and the corresponding redox-signaling pathways. We also address the use of inhibitor drugs targeting the effects of Ang-II in the context of leukocyte infiltration in these cardiovascular pathologies, and examine the clinical data supporting the relevance of blocking Ang-II-induced vascular inflammation. PURPOSE High concentrations of oxygen administered to newborn infants with respiratory failure increases oxidant stress and leads to lung injury, characterized by decreased alveolar and capillary development. Cathelicidin belongs to an important group of human antimicrobial peptides that exhibit antioxidant activity; its overexpression reduces hyperoxia-induced oxidative stress. This study evaluated the therapeutic effects of cathelicidin in hyperoxia-induced lung injury in newborn rats. METHODS AND MATERIALS Sprague Dawley rat pups were reared in either room air (RA) or hyperoxia (85% O2) and then randomly treated with low-dose (4 mg/kg) and high-dose (8 mg/kg) cathelicidin in 0.05 mL of normal saline (NS) administered intraperitoneally on postnatal days 1-6. The following six groups were obtained RA + NS, RA + low-dose cathelicidin, RA + high-dose cathelicidin, O2 + NS, O2 + low-dose cathelicidin, and O2 + high-dose cathelicidin. Lungs were harvested for Western blot and histological analyses on postnatal day 7. RESULTS Compared with the RA-reared rats, the hyperoxia-reared rats exhibited significantly lower body weights, higher mean linear intercept (MLI), lung injury score, interleukin-6, and oxidative stress marker 8-hydroxy-2'-deoxyguanosine (8-OHdG) expression but lower superoxide dismutase 1 (SOD1) and vascular endothelial growth factor (VEGF) protein expression and vascular density. Cathelicidin treatment attenuated hyperoxia-induced lung injury as demonstrated by lower MLI and injury score and higher VEGF expression and vascular density. CONCLUSIONS Cathelicidin attenuated hyperoxia-induced lung injury and caused a decrease in 8-OHdG and SOD1 protein expression, most likely by inhibiting oxidative stress in the lung. Hyperbranched polymers (HBPs) have found use in a wide range of applications, such as optical, electronic and magnetic materials, coatings, additives, supramolecular chemistry, and biomedicine. HBPs have gained attention for the development of drug delivery systems due to the presence of internal cavities in their three-dimensional globular structure that can be used to encapsulate drugs and their facile synthesis as compared to dendrimers. The composition, topology, and functionality of HBPs have been tuned to design drug carriers with better efficacies. Recent advances have been reported to introduce functional groups to enhance targeting tumor cells. HBPs have been modified to promote passive and active targeting. This review article will describe the different routes to synthesize hyperbranched polymer, their use as drug carriers for targeted drug delivery, and their functionalization with ligands for active targeting through various synthesis strategies to give the reader an extended overview of the progresses accomplished in this field. selleckchem The modification of HBPs with ligands such as peptides, oligonucleotides, and folic acid have been demonstrated to enhance the accumulation of the drug selectively at the tumor sites. The potential uses and developments of HBPs as nanoobjects for theranostics for example are discussed as perspectives. PURPOSE To evaluate the feasibility of arthroscopic reduction percutaneous fixation (ARPF) in the treatment of isolated medial malleolar fracture and to compare the results with those of conventional open reduction internal fixation (ORIF). METHODS This prospective study enrolled 77 patients with isolated medial malleolar fracture between November 2011 and February 2016. The patients were assigned to the ARPF (n = 34) and ORIF (n = 43) groups. The Olerud-Molander Ankle Score (OMAS), ankle range of motion (ROM), visual analog scale, and radiographic evaluation were determined at the scheduled follow-up. RESULTS In the ARPF group, 11 of 34 (32.4%) patients had chondral lesions. Tears of the deltoid ligament and anterior inferior tibiofibular ligament were noted in 3 (8.8%) and 15 (44.1%) patients, respectively. The mean follow-up was 5 years. The mean OMAS was higher in the ARPF group than in the ORIF group. The differences were statistically significant at 6 months (80.2 ± 4.0 for ARPF vs. 77.2 ± 4.1 for ORIF, P = 0.
