Irisin, a recently identified hormone secreted by skeletal muscle in response to exercise, exhibits anabolic effects on the skeleton primarily through the stimulation of bone formation. However, the mechanism underlying the irisin-stimulated anabolic response remains largely unknown. To uncover the underlying mechanism, we biosynthesized recombinant irisin (r-irisin) using an Escherichia coli expression system and used it to treat several osteoblast cell types. Our synthesized r-irisin could promote proliferation and differentiation of osteoblasts as evidenced by enhanced expression of osteoblast-specific transcriptional factors, including Runt-related transcription factor-2 (Runx2), Oster (Osx), as well as early osteoblastic differentiation markers such as alkaline phosphatase (Alp) and collagen type I alpha 1 (Col1a1)...

BACKGROUND: We aim to examine the effect of genetic syndromes and extracardiac anomalies (GS/EC) on single ventricle (SV) palliation with focus on hospital death, interstage mortality, and progression towards subsequent palliation stages. METHODS: 530 neonates with SV underwent first-stage palliation: Norwood (n=284,53%), shunt (n=173,33%), band (n=73,14%). Outcomes were compared between those with GS/EC (n=121,23%) and without GS/EC (n=409,77%). Regression analyses were adjusted for other risk factors (age, gender, prematurity, weight, SV anomaly, first-stage palliation surgery)...

BACKGROUND: We examined the association of pre-operative cell count abnormalities, which have been shown to be associated with outcomes in adult cardiac patients, with morbidity and mortality following surgery for congenital heart disease (CHD) in children. METHODS: We performed a retrospective cohort study on 4865 children undergoing cardiac surgery from 2004- 2014. Our exposures of interest were presence of pre-operative lymphopenia (lymphocyte count ≤ 3000 cells/μL), thrombocytopenia (platelet count < 150 x103 / μL), and neutrophilia (neutrophil count ≥ 7000 cells/ μL)...

REVIEW
Björn Lemmer, Henrik Oster
PURPOSE OF THE REVIEW: Cellular circadian clocks regulate physiological functions during day and night. It has been convincingly demonstrated that hypertension in patients suffering from diabetes mellitus or metabolic syndrome is characterized in most cases by a disturbed 24-h profile resulting in a nondipper pattern. We consider possible correlation between biological clocks and symptoms of the metabolic syndrome. RECENT FINDINGS: Changes in circadian clock function have been linked to metabolic disorders in genome-wide association studies...

REVIEW
Marike Visser, Seth C Oster
Lack of species-specific pharmacokinetic and pharmacodynamic data is a challenge for pharmaceutical and dose selection. If available, dose extrapolation can be accomplished via basic equations. If unavailable, several methods have been described. Linear scaling uses an established milligrams per kilograms dose based on weight. This does not allow for differences in species drug metabolism, sometimes resulting in toxicity. Allometric scaling correlates body weight and metabolic rate but fails for drugs with significant hepatic metabolism and cannot be extrapolated to avians or reptiles...

BACKGROUND Gelsolin amyloidosis is a very rare systemic disease presenting with a pathognomonic triad of corneal lattice dystrophy, cutis laxa, and polyneuropathy. The disease is mostly restricted to a Finnish population with known mutations (G654A, G654T) in exon 4 of the gelsolin gene. The mutations lead to errors in protein processing and folding, and ultimately leads to deposition of an amyloidogenic fragment in the extracellular space, causing the symptoms of disease. CASE REPORT We present a case of gelsolin amyloidosis in a male of African descent with an atypical clinical presentation including fevers, skin rash, polyneuropathy, and anemia...

REVIEW
Mariana Astiz, Henrik Oster
An intact communication between circadian clocks and the stress system is important for maintaining physiological homeostasis under resting conditions and in response to external stimuli. There is accumulating evidence for a reciprocal interaction between both-from the systemic to the molecular level. Disruption of this interaction by external factors such as shiftwork, jetlag, or chronic stress increases the risk of developing metabolic, immune, or mood disorders. From experiments in rodents, we know that both systems maturate during the perinatal period...

BACKGROUND: In monogastric animals, phosphorus (P) homeostasis is maintained by regulating intestinal absorption, bone mobilization, and renal excretion. Since P is a non-renewable resource, a shortage is imminent due to widespread over-usage in the farming and animal husbandry industries. As a consequence, P efficiency should be improved in pig production. We sought to characterize the transcriptional response in re-/absorbing and excreting tissues in pigs to diets varying in calcium: phosphorus ratios...

Restrictive practices continue to be used in mental health care despite increasing recognition of their harms and an international effort to reduce and ultimately eliminate their use. The aim of this qualitative study was to explore mental health nurses' views of the potential elimination of these practices. Nine focus groups were conducted with 44 mental health nurses across Australia, and the data analysed using thematic analysis. Overall, the nurses expressed significant fear about the potential elimination of restrictive practices and saw themselves as being blamed for both the use of these practices and the consequences should they be eliminated...

Respiratory syncytial virus (RSV) infection is the most common cause of lower respiratory tract infection and the leading cause of hospitalization among young children, incurring high annual costs among US children under the age of 5 years. Palivizumab has been found to be effective in reducing hospitalization and preventing serious lower respiratory tract infections in high-risk infants. This paper presents a systematic review of the cost-effectiveness studies of palivizumab and describes the main highlights of a round table discussion with clinical, payer, economic, research method, and other experts...

Primary effusion lymphoma (PEL) is a distinct clinicopathologic entity usually characterized by presentation as a lymphomatous body cavity effusion in the absence of solid tumor mass or dissemination during its clinical course. PEL can also rarely occur as a solid lymphoma involving nodal and extranodal sites and is referred to as extracavitary PEL. Here we report a unique case of extracavitary PEL in a 49year-old HIV-seropositive patient, who presented with vague abdominal pain and 20 pound weight loss. Esophagogastroduodenoscopy and colonoscopy revealed >100 broad based intestinal polyps ranging from 2 mm to 3cm in size, spreading from the duodenum to the rectum as a typical impression of "intestinal polyposis syndrome"...

The order Phyllachorales ( Pezizomycotina , Ascomycota ) is a group of biotrophic, obligate plant parasitic fungi with a tropical distribution and high host specificity. Traditionally two families are recognised within this order: Phyllachoraceae and Phaeochoraceae , based mostly on morphological and host characteristics. Currently, the position of the order within the class Sordariomycetes is inconclusive, as well as the monophyly of the order, and its internal phylogenetic structure. Here we present a phylogeny of the order Phyllachorales based on sequence data of 29 species with a broad host range resulting from a wide geographical sampling...

In 2014, persons aged 13-29 years represented 23% of the U.S. population, yet accounted for 40% of diagnoses of human immunodeficiency virus (HIV) infection during the same year (1). During 2010-2014, the rates of diagnosis of HIV infection decreased among persons aged 15-19 years, were stable among persons aged 20-24 years, and increased among persons aged 25-29 years (1). However, these 5-year age groups encompass multiple developmental stages and potentially mask trends associated with the rapid psychosocial changes during adolescence through young adulthood...

INTRODUCTION: Prophylactic intra-aortic balloon counterpulsation (pIABC) is recommended for high-risk patients undergoing coronary artery bypass grafting (CABG) surgery. Criteria for high-risk patients benefiting from pIABC are unclear. This study aimed to specifically describe the effect of pIABC on outcomes of patients with acute myocardial infarction (AMI) undergoing CABG. METHODS: In 178 of 484 AMI patients (non-ST-segment elevation myocardial infarction [NSTEMI] or ST-segment elevation myocardial infarction [STEMI] ≤5 days before surgery) without cardiogenic shock who underwent CABG between 2008 and 2013, pIABC was initiated preoperatively...
