Incongruent vaccination rates have been found in multiple US cities, one cause possibly being misleading information that is easily available on the internet through text and videos. Health care providers should be aware of the extent and content of online health information available to patients and their guardians to enhance the effectiveness of patient-physician communication. This study obtained data on vaccine-related YouTube videos and analyzed the videos' content. When misleading information was found in a video, the timing and specific type of misleading information was noted. More than two thirds of the YouTube videos contained some type of unreliable information regarding vaccine safety and effectiveness. Much of the information accessible to patients and parents vaccinating their children is misleading to a potentially dangerous extent. Health care providers should be aware of and able to provide clear counter-evidence to misleading information on YouTube in light of the findings.Glioblastoma is the most aggressive brain tumor characterized by diffuse infiltration into the normal brain parenchyma. Neural stem cells (NSCs) are known to possess the tumor-tropic migratory capacity and thus can be used as cellular vehicles for targeted delivery of therapeutic agents. In the present study, we evaluated the efficacy of herpes simplex virus thymidine kinase (HSV-TK) suicide gene therapy for glioblastoma using neural stem/progenitor cells (NS/PCs) derived from human induced pluripotent stem cells (hiPSCs). Although transduction of hiPSCs is preferable for a safe and stable supply in the clinical setting, high-level and/or constitutive HSV-TK expression was highly cytotoxic to hiPSCs. To overcome this problem, we used the tetracycline-inducible system to control the expression of HSV-TK. hiPSC-derived NS/PCs expressing HSV-TK were transplanted in an orthotopic xenograft mouse model of human glioblastoma. Glioblastoma cell growth in mice was dramatically inhibited following ganciclovir (GCV) administration. Survival of the mice was significantly prolonged with administration of GCV compared with control groups. Time-lapse imaging of organotypic brain slice cultures first demonstrated the directional migration of NS/PCs toward glioblastoma cells and the bystander killing effect upon GCV treatment. hiPSC-derived NS/PCs with HSV-TK/GCV suicide gene system may have considerable therapeutic potential for the treatment of glioblastoma.We have previously produced viral vectors (lentiviral vector, adenoviral vector and AAV) in small and in commercial scale in adherent cells using PALL's fixed-bed iCELLis® bioreactor. Recently, a company called Univercells has launched a new fixed-bed bioreactor with the same cell growth surface matrix material but with different fixed-bed structure than is used in iCELLis bioreactor. We sought to compare the new scale-X™ hydro bioreactor (2.4m) in order to see if the difference has any effect on cell growth or lentiviral vector and adenoviral vector productivity. Runs were performed using parameters optimized for viral vector production in iCELLis Nano bioreactor. Cell growth was monitored by counting nuclei, as well as by following glucose consumption and lactate production. In both bioreactor systems cells grew well, and the cell distribution was found quite homogeneous in scale-X bioreactor. Univercells scale-X bioreactor was proven to be at least equally efficient or even improved in both lentiviral vector and adeno viral vector production. Based on the results, the same protocol and parameters used in viral vector production in iCELLis bioreactor can also be successfully used for the production in scale-X bioreactor system.Phenomenon This study explores professional identity formation during a final year of medical school designed to ease the transition from student to practitioner. Although still part of the undergraduate curriculum, this "transitional year" gives trainees more clinical responsibilities than in earlier rotations. Trainees are no longer regarded as regular clerks but work in a unique position as "semi-physicians," performing similar tasks as a junior resident during extended rotations. Approach We analyzed transcripts from interviews with 21 transitional-year medical trainees at University Medical Center Utrecht about workplace experiences that affect the development of professional identity. We used Social Identity Approach as a lens for analysis. This is a theoretical approach from social psychology that explores how group memberships constitute an important component of individual self-concepts in a process called 'social identification.' The transcripts were analyzed using thematic analysis, with a focus onrvisors who could confirm their fit with the group, giving them a sense of belonging (i.e., in-group ties). Insights Using the three-dimension model of social identification revealed how students come to identify with the social group of practitioners in the context of a transitional year with extended rotations, increased clinical responsibilities, and being in the position of a "semi-physician." These findings shed light on the identity transition from student to practitioner within such a curricular structure.In the 1980s and early 1990s, Dr. Barrie Carter served as the Chief of the Laboratory of Molecular and Cellular Biology, in the National Institute of Diabetes and Digestive and Kidney Diseases, at the National Institutes of Health. During that time, his group performed seminal work in Adeno-Associated Virus Type 2 (AAV2) biology, including creating one of the first infectious clones of AAV2 and some of the first packaged AAV2 vectors. This work contributed substantially to the development of AAVs as gene therapy vectors. Part of the success of the group was due to Dr. Carter's ability to attract and manage a diverse team of talented individuals who synergized into a collaborative group that was more than the sum of its parts. This review describes some of the promising practices employed by the Carter group, which allowed such a diverse group to function so well. These practices included promoting a culture of co-mentoring, open communication, and respectful questioning.Arterial stiffness is a major independent risk factor for cardiovascular complications causing isolated systolic hypertension and increased pulse pressure in the microvasculature of target organs. Stiffening of the arterial wall is determined by common mechanisms including reduced elastin/collagen ratio, production of elastin cross-linking, reactive oxygen species-induced inflammation, calcification, vascular smooth muscle cell stiffness, and endothelial dysfunction. This brief review will discuss current biological mechanisms by which other cardiovascular risk factors (eg. aging, hypertension, diabetes mellitus, and chronic kidney disease) cause arterial stiffness, with a particular focus on recent advances regarding nuclear mechanotransduction, mitochondrial oxidative stress, metabolism and dyslipidemia, genome mutations, and epigenetics. Targeting these different molecular pathways at different time of cardiovascular risk factor exposure may be a novel approach for discovering drugs to reduce arterial stiffening without affecting artery strength and normal remodeling.It is estimated that >2 million patients are living with an amputation in the United States. Peripheral artery disease (PAD) and diabetes mellitus account for the majority of nontraumatic amputations. The standard measurement to diagnose PAD is the ankle-brachial index, which integrates all occlusive disease in the limb to create a summary value of limb artery occlusive disease. Despite its accuracy, ankle-brachial index fails to well predict limb outcomes. There is an emerging body of literature that implicates microvascular disease (MVD; ie, retinopathy, nephropathy, neuropathy) as a systemic phenomenon where diagnosis of MVD in one capillary bed implicates microvascular dysfunction systemically. MVD independently associates with lower limb outcomes, regardless of diabetic or PAD status. The presence of PAD and concomitant MVD phenotype reveal a synergistic, rather than simply additive, effect. The higher risk of amputation in patients with MVD, PAD, and concomitant MVD and PAD should prompt aggressive foot surveillance and diagnosis of both conditions to maintain ambulation and prevent amputation in older patients.OBJECTIVE Vascular progenitor cells (VPCs), which are able to differentiate into both endothelial cells and smooth muscle cells, have the potential for treatment of ischemic diseases. Generated by pluripotent stem cells, VPCs carry the risk of tumorigenicity in clinical application. This issue could be resolved by direct lineage conversion, the induction of functional cells from another lineage by using only lineage-restricted transcription factors. Here, we show that induced VPCs (iVPCs) can be generated from fibroblasts by ETS (E-twenty six) transcription factors, Etv2 and Fli1. Approach and Results Mouse fibroblasts were infected with lentivirus encoding Etv2 and Fli1. Cell colonies appeared in Fli1- and Etv2/Fli1-infected groups and were mechanically picked. The identity of cell colonies was confirmed by proliferation assay and reverse-transcription polymerase chain reaction with vascular markers. Etv2/Fli1- infected cell colonies were sorted by CD144 (CDH5, VE-cadherin). We defined that CD144-positive iVPCs maintained its own population and expanded stably at multiple passages. iVPCs could differentiate into functional endothelial cells and smooth muscle cells by a defined medium. The functionalities of iVPC-derived endothelial cells and smooth muscle cells were confirmed by analyzing LDL (low-density lipoprotein) uptake, carbachol-induced contraction, and tube formation in vitro. this website Transplantation of iVPCs into the ischemic hindlimb model enhanced blood flow without tumor formation in vivo. Human iVPCs were generated by ETV2 and FLI1. CONCLUSIONS We demonstrate that ischemic disease curable iVPCs, which have self-renewal and bipotency, can be generated from mouse fibroblasts by enforced ETS family transcription factors, Etv2 and Fli1 expression. Our simple strategy opens insights into stem cell-based ischemic disease therapy.OBJECTIVE HuR (human antigen R)-an RNA-binding protein-is involved in regulating mRNA stability by binding adenylate-uridylate-rich elements. This study explores the role of HuR in the regulation of smooth muscle contraction and blood pressure. Approach and Results Vascular HuRSMKO (smooth muscle-specific HuR knockout) mice were generated by crossbreeding HuRflox/flox mice with α-SMA (α-smooth muscle actin)-Cre mice. As compared with CTR (control) mice, HuRSMKO mice showed hypertension and cardiac hypertrophy. HuR levels were decreased in aortas from hypertensive patients and SHRs (spontaneously hypertensive rats), and overexpression of HuR could lower the blood pressure of SHRs. Contractile response to vasoconstrictors was increased in mesenteric artery segments isolated from HuRSMKO mice. The functional abnormalities in HuRSMKO mice were attributed to decreased mRNA and protein levels of RGS (regulator of G-protein signaling) protein(s) RGS2, RGS4, and RGS5, which resulted in increased intracellular calcium increase.
