BACKGROUND: Off-pump coronary artery bypass grafting (OPCAB) helps reduce systemic inflammatory changes by maintaining native pulsatile flow. This analysis evaluates the outcomes of OPCAB at a Veterans Affairs Medical Center (VAMC) and evaluates the use of beating heart on-pump (BHOP) bypass grafting as an empiric therapy for high-risk patients. METHODS: We performed a retrospective analysis of 756 patients who underwent coronary bypass grafting between 2004-2015 at a single VAMC...

BACKGROUND: We performed a meta-analysis to assess the presence of a day-of-week rhythmic variability of acute aortic rupture or dissection (AARD) onset. METHODS: Eligible studies were observational studies enrolling patients with AARD and reporting day-of-week variation of AARD. Study-specific estimates, i.e. day-of-week incidence of AARD, were combined using the random-effects model. Chronobiological analysis was performed by applying a partial Fourier series to pooled day-of-week incidence by using the inverse-variance weighted least-squares method...

The role of Phospholipase D (PLD) in cancer development and management has been a major area of interest for researchers. The purpose of this mini-review is to explore PLD and its distinct role during chemotherapy including anti-apoptotic function. PLD is an enzyme that belongs to the phospholipase super family and is found in a broad range of organisms such as viruses, yeast, bacteria, animals, and plants. The function and activity of PLD are widely dependent on and regulated by neurotransmitters, hormones, small monomeric GTPases, and lipids...

Levels of maturation-promoting factor (MPF) in oocytes decline after vitrification, and this decline has been suggested as one of the main causes of low developmental competence resulting from cryoinjury. Here, we evaluated MPF activity in vitrified mouse eggs following treatment with caffeine, a known stimulator of MPF activity, and/or the proteasome inhibitor MG132. Collected MII oocytes were vitrified and divided into four groups: untreated, 10 mM caffeine (CA), 10 μM MG132 (MG), and 10 mM caffeine +10 μM MG132 (CA+MG)...

Impairment of wound healing is a common problem in individuals with diabetes. Adiponectin, an adipocyte-derived cytokine, has many beneficial effects on metabolic disorders such as diabetes, obesity, hypertension, and dyslipidemia. C1q/TNF-Related Protein 9 (CTRP9), the closest paralog of adiponectin, has been reported to have beneficial effects on wound healing. In the current study, we demonstrate that CTRP9 regulates growth, differentiation, and apoptosis of HaCaT human keratinocytes. We found that CTRP9 augmented expression of transforming growth factor beta 1 (TGFβ1) by transcription factor activator protein 1 (AP-1) binding activity and phosphorylation of p38 in a dosedependent manner...

The origin of hypogonadism, a condition including both symptoms and biochemical criteria of androgen deficiency, in type 2 diabetes is poorly known. In a cross-sectional study of 267 unselected patients, we analyzed the potential correlation of several clinical and biochemical variables as well as chronic micro- and macrovascular diabetic complications with hypogonadism. Hypogonadism was present in 46 patients (17.2%) using a cutoff of total testosterone 10.4 nmol/L and in 31 (11.6%) with a cutoff of 8 nmol/L...

OBJECTIVE: To identify candidate microRNAs that potentially regulate the initiation and progression of osteoarthritis. METHODS: Osteoarthritis was induced in 10-12 week old male wild-type C57BL6 mice and in mice resistant to aggrecanase cleavage (Acan p.374ALGS→374NVYS) by destabilization of the medial meniscus (DMM). Osteoarthritis pathology was scored histologically. RNA from cartilage and subchondral bone were harvested in parallel by laser micro-dissection at 1 and 6 weeks post-surgery...

Sickle cell disease (SCD)-associated priapism is characterized by decreased nitric oxide (NO) signaling and downregulated phosphodiesterase (PDE)5 protein expression and activity in the penis. Priapism is also associated with testosterone deficiency, but molecular mechanisms underlying testosterone effects in the penis in SCD are not known. Given the critical role of androgens in erection physiology and NO synthase (NOS)/PDE5 expression, we hypothesized that testosterone replacement to eugonadal testosterone levels reduces priapism by reversing impaired endothelial (e)NOS activity and molecular abnormalities involving PDE5...

Microcirculation impairment and related vasculopathy is a hallmark of systemic sclerosis. Digital ulcers are second only to Raynaud's phenomenon as a vascular complication occurring in scleroderma patients. Digital ulcers are painful and generate disability. Furthermore, patients may develop recurrent digital ulcers and one may ask whether the outcomes of such patients might be different to those of unaffected ones. Recently several registries have provided relevant information about digital ulcers. Male sex and severe skin disease seem to be the main associated factors observed in several registries...

Forty years have passed since it was first recognized that patients with autoimmune rheumatic disease have an increased risk of fatal and non-fatal cardiovascular (CV) events (1) Although initial reports focused on rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), similar findings were verified subsequently in patients with psoriasis (Ps) and/or psoriatic arthritis (PsA) and spondyloarthritis. An early feature of the atherosclerotic lesion is infiltration with inflammatory cells, particularly monocytes/macrophages, and the presence of these cells in mature plaque elevates the risk of plaque rupture and thrombosis (2)...

Promoters play a pivotal role in integrating and processing the signals related to transcription initiation. Strong natural viral promoters, such as hCMV or SV40E, have been routinely employed to achieve a high rate of gene expression in ubiquitously used Chinese hamster ovary (CHO) cells. However, viral promoters are susceptible to epigenetic silencing and lack precise regulation levers. This has paved the way to more sensible control elements: endogenous, inducible and synthetic promoters. In this review we summarise and discuss the use of natural viral, mammalian and endogenous promoters, as well as recent advances in synthetic promoters and inducible systems for protein expression in CHO cells...

BACKGROUND: Preterm infants have low plasma levels of erythropoietin (EPO), providing a rationale for the use of erythropoiesis-stimulating agents (ESAs) to prevent or treat anaemia and to provide neuro protection and protection against necrotising enterocolitis (NEC). Darbepoetin (Darbe) and EPO are currently available ESAs. OBJECTIVES: To assess the effectiveness and safety of ESAs (erythropoietin (EPO) and/or Darbe) initiated early (before eight days after birth) compared with placebo or no intervention in reducing red blood cell (RBC) transfusions, adverse neurological outcomes, and feeding intolerance including necrotising enterocolitis (NEC) in preterm and/or low birth weight infants...

Different tail enigneered resorcinarenes have been examined towards the insulin fibrillation via experimental and computational studies. The resorcinarene showed a promising effect on the inhibition of insulin fibrillalition via ThT assay, CD spectra, and AFM images. Both ThT assay and computational results indicate the tail from the resorcinarene has an impact on insulin fibrillation by either inhibition or promotion because of the resident position on insulin. These observations have significant biological implications in the design of lead drug molecules as well as the development of potential therapeutic strategies...

Primary intraocular lymphomas are rare tumours that can be further subdivided into primary vitreoretinal and the even rarer primary uveal lymphoma. The incidence of primary vitreoretinal lymphoma (PVRL) has increased during the last few decades. Differential diagnostic distinction between lymphoma and posterior uveitis is often difficult, so that adequate diagnosis and treatment is often delayed. This is fatal, because PVRL is often associated with primary central nervous lymphoma. To confirm the diagnosis, prior treatment of cytological or histological detection of lymphoma cells is the gold standard...

Optical coherence tomography (OCT) enables noninvasive high-resolution 3D imaging of the human retina, and thus plays a fundamental role in ophthalmology. Via OCT examination, even subtle retinal changes can be captured, which occur in very early stages of different diseases (e.g., glaucoma, diabetes mellitus, or age-related macular degeneration). Yet, analyzing the resulting data is challenging. Conventionally, OCT data are strongly aggregated via automated methods. While this reduces the amount of information to be analyzed, it also makes it difficult, if not impossible, to identify small and localized retinal changes...

Effects of early and permanent footwear use are not well understood. The aim of this study was to investigate the effects of habituation to footwear on foot strike patterns of children and adolescents. Healthy habitually barefoot and shod participants (aged 6-18 years) from South Africa (n=288) and Germany (n=390) performed multiple 20-m jogging and running trials with and without shoes. Each foot strike was captured using a high-speed camera to determine a rearfoot or non-rearfoot strike. The probability of a rearfoot strike in both cohorts and each age was analyzed by using a mixed-effects logistic regression adjusted for possible confounders...

Introduction In patients with localised renal cell carcinoma, the only curative treatment option is surgical tumour excision. Current national and European guidelines recommend partial nephrectomy in the form of an open or minimally-invasive procedure in case of small tumours. The aim of this study was to examine the use of radical (RN) or partial (PN) nephrectomy performed as open or minimally-invasive procedures in patients with pT1 /pT2 renal cell carcinoma at a tertiary referral centre. Patients and Methods This retrospective study included a total of 758 patients with localised renal cell carcinoma (pT1/pT2), who underwent PN or RN between 01/2008 and 10/2014...

Previous studies have evidenced that inflammation and endothelial dysfunction have a crucial role in erectile dysfunction (ED). Increased monocyte count or activity and lower high-density lipoprotein cholesterol (HDL-C) levels have been associated with inflammation. The monocyte to HDL-C ratio (MHR) is a recently emerged indicator of inflammation. We aimed to investigate the relationship between MHR and ED. In this retrospective study, a total of 120 patients were enrolled, 60 of them having ED and 60 having a normal erectile function...
