Middle East respiratory syndrome coronavirus (MERS-CoV) is a lineage C betacoronavirus that since its emergence in 2012 has caused outbreaks in human populations with case-fatality rates of ∼36%. As in other coronaviruses, the spike (S) glycoprotein of MERS-CoV mediates receptor recognition and membrane fusion and is the primary target of the humoral immune response during infection. Here we use structure-based design to develop a generalizable strategy for retaining coronavirus S proteins in the antigenically optimal prefusion conformation and demonstrate that our engineered immunogen is able to elicit high neutralizing antibody titers against MERS-CoV...

The purpose of this study is to examine whether water and air pollutants have a relationship with an increase in the genetic disorders Turner syndrome and Down syndrome, which are caused by congenital chromosomal abnormalities, and to generate a hypothesis about the genetic health effects of environmental pollutants. A panel regression based on random effect was conducted on South Korea's metropolitan councils from 2012 to 2014. The dependent variable was the number of Turner syndrome and Down syndrome cases, and the main independent variables were those regarding the water and air pollution...

BACKGROUND: Turner syndrome (TS) is associated with an increased risk of cardiovascular disease. Non-high-density lipoprotein cholesterol (non-HDL-C) is a convenient measure of atherogenicity (normal concentration <120 mg/dL) but has not been investigated in TS. We aim to evaluate non-HDL-C patterns in a cohort of pediatric and young adult females with TS. METHODS: A retrospective chart review was used to obtain demographics, body composition, genetic reports, and lipid profiles in females with TS...

While white-nose syndrome (WNS) has decimated hibernating bat populations in the Nearctic, species from the Palearctic appear to cope better with the fungal skin infection causing WNS. This has encouraged multiple hypotheses on the mechanisms leading to differential survival of species exposed to the same pathogen. To facilitate intercontinental comparisons, we proposed a novel pathogenesis-based grading scheme consistent with WNS diagnosis histopathology criteria. UV light-guided collection was used to obtain single biopsies from Nearctic and Palearctic bat wing membranes non-lethally...

A 55-year-old man with large B-cell lymphoma developed atraumatic left shoulder pain. F-FDG PET/CT revealed new left supraspinatus and infraspinatus muscle uptake while the initial disease resolved. Given the discrepancy between initial disease treatment response and new left shoulder findings, an MRI scan was performed. This demonstrated diffuse supraspinatus and infraspinatus muscle edema and enhancement with no focal lesion. Muscle biopsy was negative for lymphoma, but features of muscle denervation were seen...

BACKGROUND: The aim of the study was to assess health-related quality of life (HR-QoL) in children with Turner syndrome in comparison with controls. METHODS: We prospectively recruited 16 female girls with Turner syndrome (mean age 15.2±2.6 years) and 78 female controls (mean age 12.7±2.8 years) in randomly selected schools. We used the PedsQL, a generic HR-QoL questionnaire (self and parents' versions). RESULTS: Global HR-QoL scores in Turner syndrome were lower than controls for self-reports (respectively, 74...

OBJECTIVES: Turner syndrome (TS), resulting from complete/partial X chromosomal monosomy, is associated with multiple co-morbidities and increased mortality. Although multidisciplinary management is recommended, TS women's health care is sub-optimal. This study evaluates a multidisciplinary adult TS service. METHODS: Retrospective cohort study of 82 patients attending the quarterly TS clinic from December 2003 to December 2014. Evaluation included (1) demographics, (2) TS standardized co-morbidity screening, and (3) estrogen therapy use...

Parsonage-Turner syndrome (PTS) is a rare neuropathy that commonly presents as unexpected severe shoulder and arm pain that eventually subsides while weakness or paralysis ensues. During exceptions to this classic presentation, confirming PTS can be challenging. Alternative causes of upper extremity pain may confound the diagnostic algorithm. Moreover, objective findings from necessary diagnostic tests depend on when those tests are performed. We present an atypical onset of PTS, whereby the initial presentation of severe neuropathic pain was preceded by mild shoulder pain that should decrease one's clinical suspicion for PTS...

Congenital heart disease (CHD) is present in approximately 50% of patients with trisomy 21 (T21) and Turner syndrome (TS). According to the American Academy of Pediatrics, every patient with these genetic disorders should have a postnatal echocardiogram. T21 is usually associated with atrioventricular (30%-60%), atrial (16%-21%), or ventricular septal defects (14%-27%). TS is usually associated with left-sided heart disease. However, the spectrum of CHD in these genetic disorders is wider than those mentioned lesions...

Turner syndrome (TS) is a chromosomal disorder that affects 1:2,000 females. It results from either the complete or partial loss of the X chromosome as well as other aberrations. Clinical features of TS include short stature, delayed puberty, and congenital cardiac malformations. TS children also have an increased prevalence of cardiometabolic risk factors, which predisposes them to complications like coronary artery disease, cerebrovascular-related deaths, and aortic dissection. Early cardiac imaging, such as echocardiography and cardiac magnetic resonance imaging, are recommended to detect underlying aortic pathology...

BACKGROUND: Intestinal failure-associated liver disease (IFALD) causes significant morbidity in neonates with short bowel syndrome (SBS) dependent on parenteral nutrition (PN). Resected ileum, with loss of the ileocecal valve (ICV), is the most common anatomy in SBS, yet its impact on IFALD has not been adequately studied. METHODS: Neonatal piglets were randomized to 75% intestinal resection with jejunocolic anastomosis (JC, n = 12), 75% resection with jejunoileal anastomosis and intact ICV (JI, n = 13), PN-fed sham (sham, n = 14), or sow-fed control (SF, n = 8)...

Neurofibromatosis type 1 (NF1) is classically defined by the presence of multiple café-au-lait macules as one of the diagnostic criteria. Turner syndrome (TS) can also present with café-au-lait macules along with short stature. Our patient is the fifth reported with both NF1 and TS and the first who has been on growth hormone for short stature associated with TS.

Turner syndrome affects 25-50 per 100,000 females and can involve multiple organs through all stages of life, necessitating multidisciplinary approach to care. Previous guidelines have highlighted this, but numerous important advances have been noted recently. These advances cover all specialty fields involved in the care of girls and women with TS. This paper is based on an international effort that started with exploratory meetings in 2014 in both Europe and the USA, and culminated with a Consensus Meeting held in Cincinnati, Ohio, USA in July 2016...

BACKGROUND: While the main role of growth hormone (GH) replacement therapy in children is to promote linear growth, GH has also an effect on lipids and body composition. There is an ongoing discussion whether discontinuation of GH treatment is associated with deterioration of lipids. METHODS: We analyzed weight status [as body mass index-standard deviation score (BMI-SDS)], insulin like growth factor (IGF)-1, triglycerides, total, low-density liporptoein (LDL)- and high-density lipoprotein (HDL)-cholesterol at the end of GH treatment and in mean 6 months later in 90 adolescents (53 with GH deficiency, 16 with Turner syndrome [TS] and 21 born small-for-gestational age [SGA])...

We report 15 individuals with de novo pathogenic variants in WDR26. Eleven of the individuals carry loss-of-function mutations, and four harbor missense substitutions. These 15 individuals comprise ten females and five males, and all have intellectual disability with delayed speech, a history of febrile and/or non-febrile seizures, and a wide-based, spastic, and/or stiff-legged gait. These subjects share a set of common facial features that include a prominent maxilla and upper lip that readily reveal the upper gingiva, widely spaced teeth, and a broad nasal tip...

Genetic mouse model (39,XO) for human Turner Syndrome (45,XO) harboring either a single maternally inherited (Xm) or paternally inherited (Xp) chromosome show a pronounced difference in survival rate at term. However, a detailed comparison of XmO and XpO placentas to explain this difference is lacking. We aimed to investigate the morphological and molecular differences between XmO and XpO term mouse placentas. We observed that XpO placentas at term contained a significantly larger area of glycogen cells (GCs) in their outer zone, compared to XmO, XX, and XY placentas...
