A blueprint for the next generation of ELSI research, training, and outreach in regenerative medicine.

Regenerative medicine has attracted the interest of scientists, physicians, and patient communities, and as well as policy-makers and the broader public given related ethical, legal, and social implications. Here we examine past initiatives in the ethical, legal and social implications arena in regenerative medicine, and offer our views on actionable priorities for the future in six key areas: capacity building, policy, engagement with industry, resaerch ethics, communication, and community building.

New advances in CNS immunity against viral infection.

The central nervous system (CNS) is an immunologically specialized organ where restrictive barrier structures protect the parenchyma from inflammation and infection. This protection is important in preventing damage to non-renewable resident cell populations, such as neurons, responsible for functions ranging from executive to autonomic. Despite these barriers, the CNS can be infected through several entry portals, giving rise to meningitis and encephalitis.

Nerve Bundle Hydrodissection and Sexual Function after Robot Prostatectomy.

Background And Objectives: Loss of erectile function is common after prostatectomy, and surgeons have long sought techniques that reduce this adverse outcome. This study was conducted to assess erectile function after robot-assisted laparoscopic prostatectomy, with and without hydrodissection (HD) of the neurovascular bundles (NVBs).

Methods: Using a database of 335 consecutive RALP procedures conducted by 2 surgeons, we identified all nerve-sparing surgeries performed by HD or standard dissection (SD).

UVC radiation as an effective disinfectant method to inactivate human papillomaviruses.

Endocavitary ultrasound probes are part of a commonly used procedure in the clinical arena. The cavities examined, vaginal canal and cervix, anal canal, and oral cavity are all areas commonly infected with the human papillomavirus (HPV), thus making them susceptible to contamination by HPV. It has been demonstrated that these probes can remain contaminated with high-risk HPV even when approved disinfection protocols have been performed.

5'-methylschweinfurthin G reduces chondrosarcoma tumor growth .

New treatment options are urgently required in the field of chondrosarcoma, particularly of chondrosarcomas with a well-differentiated hyaline cartilage-like extracellular matrix (e.g., collagen II and proteoglycan-rich) phenotype, notoriously resistant to drug penetration, and having potential of progression towards higher grade.

Improvements of transmit efficiency and receive sensitivity with ultrahigh dielectric constant (uHDC) ceramics at 1.5 T and 3 T.

Purpose: Incorporating high dielectric constant (HDC) materials into radiofrequency (RF) coils has been shown to effectively improve RF coil performance at 7 and 3 T because of the induced displacement current in the high dielectric constant materials. The displacement current is proportional to the RF field frequency and permittivity of the material. The aim of this paper is to investigate the effect of high dielectric constant materials with even greater permittivity on the RF field at 1.

A Case of Tracheobronchomalacia Mimicking Acute Pulmonary Embolism.

BACKGROUND Pulmonary embolism is a common acute postoperative complication and is associated with 100,000 deaths per year in the USA. Tracheobronchomalacia is an uncommon condition, which presents with similar symptoms to pulmonary embolism, including hypoxemia, tachycardia, and shortness of breath. We describe a case of a patient who presented with postoperative pulmonary symptoms that were initially thought to be due to pulmonary embolism.

Ligand-mediated cytoplasmic retention of the Ah receptor inhibits macrophage-mediated acute inflammatory responses.

The Ah receptor (AHR) has been shown to exhibit both inflammatory and anti-inflammatory activity in a context-specific manner. In vivo macrophage-driven acute inflammation models were utilized here to test whether the selective Ah receptor modulator 1-allyl-7-trifluoromethyl-1H-indazol-3-yl]-4-methoxyphenol (SGA360) would reduce inflammation. Exposure to SGA360 was capable of significantly inhibiting lipopolysaccharide (LPS)-mediated endotoxic shock in a mouse model, both in terms of lethality and attenuating inflammatory signaling in tissues.

Brain Metal Distribution and Neuro-Inflammatory Profiles after Chronic Vanadium Administration and Withdrawal in Mice.

Vanadium is a potentially toxic environmental pollutant and induces oxidative damage in biological systems including the central nervous system (CNS). Its deposition in brain tissue may be involved in the pathogenesis of certain neurological disorders which after prolonged exposure can culminate into more severe pathology. Most studies on vanadium neurotoxicity have been done after acute exposure but in reality some populations are exposed for a lifetime.

Patient Handoff Education: Are Medical Schools Catching Up?

Communication errors during shift-to-shift handoffs are a leading cause of preventable adverse events. Nevertheless, handoff skills are variably taught at medical schools. The authors administered questionnaires on handoffs to interns during orientation.

Surgical treatment of displaced pediatric lateral condyle fractures of the humerus by the posterior approach.

The surgical approach for open reduction and internal fixation of lateral condyle fractures in children is controversial. Some authors recommend the lateral approach to the elbow over the posterior approach because of theoretical concern for injury to the vascular supply of the distal humerus and potential avascular necrosis (AVN). The purpose of this retrospective case series study is to report the outcomes of open reduction and internal fixation of displaced lateral condyle fractures of the humerus by the posterior approach.

Role of Computed Tomography in the Classification of Pediatric Pelvic Fractures-Revisited.

Objectives: To determine the need for computerized tomography (CT) scans in the assessment of pediatric pelvic fractures.

Design: Retrospective Chart Review.

Setting: Level-1 Pediatric Trauma Center.

Salve and Burdock: A Safe, Effective Amish Remedy for Treatment of Traumatic Wounds?

Background: Amish patients show a demonstrated preference for traditional, herbal remedies over modern medical interventions such as skin grafting. One such remedy is a mixture of Burn & Wound Ointment (B & W Ointment; Holistic Acres, LLC; Newcomerstown, Ohio) and steeped burdock leaves. Although both have demonstrated some antimicrobial and wound healing properties, burdock and/or the combination of B & W Ointment and burdock has never been studied to determine its purported ability to reduce pain, prevent infection, and accelerate wound healing.

Review of key concepts in magnetic resonance physics.

MR physics can be a challenging subject for practicing pediatric radiologists. Although many excellent texts provide very comprehensive reviews of the field of MR physics at various levels of understanding, the authors of this paper explain several key concepts in MR physics that are germane to clinical practice in a non-rigorous but practical fashion. With the basic understanding of these key concepts, practicing pediatric radiologists can build on their knowledge of current clinical MR techniques and future advances in MR applications.

Trends in cataract surgery training curricula.

Purpose: To evaluate trends in cataract surgery training curricula and factors affecting timing of resident participation as a primary surgeon.

Setting: Pennsylvania State College of Medicine, Hershey, Pennsylvania, USA.

Design: Cross-sectional study of anonymous survey results.

Evolution and Cryo-electron Microscopy Capsid Structure of a North American Bat Adenovirus and Its Relationship to Other Mastadenoviruses.

Unlabelled: Since the first description of adenoviruses in bats in 2006, a number of micro- and megabat species in Europe, Africa, and Asia have been shown to carry a wide diversity of adenoviruses. Here, we report on the evolutionary, biological, and structural characterization of a novel bat adenovirus (BtAdV) recovered from a Rafinesque's big-eared bat (Corynorhinus rafinesquii) in Kentucky, USA, which is the first adenovirus isolated from North American bats. This virus (BtAdV 250-A) exhibits a close phylogenetic relationship with Canine mastadenovirus A (CAdV A), as previously observed with other BtAdVs.

WDR5 high expression and its effect on tumorigenesis in leukemia.

WD repeat domain 5 (WDR5) plays an important role in various biological functions through the epigenetic regulation of gene transcription. However, the oncogenic effect of WDR5 in leukemia remains largely unknown. Here, we found WDR5 expression is increased in leukemia patients.

Chronic odorant exposure upregulates acquisition of functional properties in cultured embryonic chick olfactory sensory neurons.

Neuronal development and differentiation is modulated by activity-dependent mechanisms that stimulate endogenous neurogenesis and differentiation to promote adaptive survival of the organism. Studies on bird odor imprinting have shown how sensory stimuli or environmental influences can affect neonatal behavior, presumably by remodeling the developing nervous system. It is unclear whether these changes originate from the sensory neurons themselves or from the brain.

Does body mass index or weight perception affect contraceptive use?

Objective: Overweight and obese women may avoid contraceptive methods they believe are associated with weight gain. The objective of this study was to examine the role of weight and weight perception on contraceptive use.

Study Design: Using cross-sectional data from the MyNewOptions study, we analyzed contraceptive use among 987 privately insured, sexually active women aged 18-40 years.
