Bronchopulmonary dysplasia (BPD) is a chronic lung injury characterized by impaired alveologenesis that may persist into adulthood. Rat models of BPD using varying degrees of hyperoxia to produce injury either cause early mortality or spontaneously recover following removal of the inciting stimulus, thus limiting clinical relevance. We sought to refine an established rat model induced by exposure to 60% O2 from birth by following hyperoxia with intermittent hypoxia (IH). Rats exposed from birth to air or 60% O2 until day 14 were recovered in air with or without IH (FiO2 = 0...

BACKGROUND: There is little data on the incidence of diabetes complications in young onset type 1 diabetes (T1DM) and type 2 diabetes (T2DM) in non European populations. METHODS: From a tertiary diabetes centre, Chennai, India, we recruited 108 T1DM (defined by abrupt onset of symptoms or diabetic ketoacidosis, absent insulin reserve requiring insulin treatment) and 90 T2DM participants (defined by absence of ketosis, good beta-cell reserve, and good response to oral agents) who were diagnosed between the ages of 10 and 25years, and without any evidence of diabetes complications at diagnosis...

OBJECTIVES: All patients with lower extremity peripheral arterial disease (LE-PAD) should benefit from recommended pharmacologic therapies including antiplatelet agents, angiotensin converting enzyme (ACE) inhibitors or Angiotensin receptor blockers (ARBs), and HMG-CoA-reductase inhibitors (statins). In the present study, this triple therapy was defined as the best medical treatment. This study was designed to determine the number of patients who received best medical treatment at admission and at discharge from a vascular surgery department...

OBJECTIVES: We aimed to assess the outcome of a large Takayasu arteritis (TAK) cohort using the vasculitis damage index (VDI) and quality of life (QoL) scale, tools which have been validated for vasculitis. METHODS: Disease activity, damage and QoL were cross-sectionally evaluated in 165 TAK patients from 6 centres. SF-36 were applied to 51 age-matched healthy controls (HC). Persistent activity for ≥6 months was considered as treatment resistance (r-TAK). The correlation between VDI, clinical characteristics and mental (MCS)/physical (PCS) component scores of SF-36 were analysed...

PURPOSE OF REVIEW: Primary hypertension is characterized by Na excess and K deficit in the body, which together are key to its pathogenesis. These derangements work jointly in the brain and the peripheral vascular wall to establish hypertension. In this review, we highlight recent evidence describing the central mechanisms through which Na surfeit and K deficit enhance sympathetic nerve activity, thereby raising peripheral vascular resistance and generating hypertension. RECENT FINDINGS: Animal studies point to a small increase in plasma and cerebrospinal fluid (CSF) [Na], a small decrease in CSF [K], and increased levels of circulating angiotensin II, aldosterone, and endogenous ouabain as the central signals evoking hypertension...

BACKGROUND: Administration of radiocontrast during endovascular procedures for peripheral arterial disease may cause acute kidney injury, which generally recovers with supportive treatment. Long-term effects of endovascular procedures on renal function remain to be investigated. METHOD: This retrospective observational cohort study includes all patients who newly presented to the vascular surgery outpatient clinic with rutherford class II or III peripheral arterial disease and who were treated with either supervised exercise therapy or endovascular interventions...

Cytomegaloviruses (CMVs) establish persistent, systemic infections and cause disease by maternal-fetal transfer, suggesting that their dissemination is a key target for anti-viral intervention. Late clinical presentation has meant that human CMV dissemination is not well understood. Murine CMV provides a tractable model. Whole mouse imaging of virus-expressed luciferase has proved a useful way to track systemic infections. MCMV, in which the abundant lytic gene M78 was luciferase tagged via a self-cleaving peptide (M78-LUC), allowed serial, unbiased imaging of systemic and peripheral infection without significant virus attenuation...

BACKGROUND: Diabetic hyperglycemia damages peripheral nerves by triggering ischemia, oxidative stress, and inflammation. Alpha-lipoic acid (ALA) and methylcobalamin (MC) are known to improve signs of diabetic peripheral neuropathy (DPN), possibly by enhancing neural and vascular endothelial cell metabolism and antioxidant capacity. We evaluated differences in efficacy following short-term MC or ALA treatment on DPN symptoms to guide clinical drug selection. METHODS: Forty DPN patients were randomly divided into MC and ALA treatment groups (n=20/20) and assessed by the Toronto Clinical Neuropathy Scoring System (TCSS), total symptom score (TSS), visual analog scale (VAS) of positive symptoms, and easy sensory test (EST) for negative symptoms before and after 2 weeks of treatment...

BACKGROUND: To evaluate the ability of community-based exercise programmes to facilitate public participation in exercise and hence improved cardiovascular health, we assessed the respective impacts of: a continuously monitored exercise programme based within our university (study 1); a Valleys Regional Park-facilitated community-based outdoor exercise programme (study 2); a Wales National Exercise Referral Scheme-delivered exercise-referral programme (study 3). METHODS: Biomolecular (monocytic PPARγ target gene expression), vascular haemodynamic (central/peripheral blood pressure, arterial stiffness), clinical (insulin sensitivity, blood lipids) and anthropometric (body mass index, waist circumference, heart rate) parameters were investigated using RT-PCR, applanation tonometry, chemical analysis and standard anthropometric techniques...

The scalp is the most frequent site of occurrence of malignant tumors. As an area that is generally neglected by the patient and not closely monitored during physical examinations, scalp tumors can go unnoticed until they become malignant. The present study reports 3 cases of rare giant malignant tumors of the scalp, namely a peripheral nerve sheath tumor, a fibrous tumor and a malignant proliferating trichilemmal tumor, that were treated at The First Bethune Hospital of Jilin University (Changchun, China)...

Hypertension is an important risk factor for premature death as it increases the probability of stroke, myocardial infarction, and heart failure. Antihypertensive drugs can decrease cardiovascular (CV) morbidity and mortality. The majority of hypertensive patients need more than one antihypertensive agent to attain blood pressure (BP) targets. Monotherapy can effectively reduce BP only in 20%-40% of patients. Multiple mechanisms including increased peripheral vascular resistance, increased cardiac work, and hypervolemia are involved in the pathogenesis of hypertension...

Progressive myoclonus epilepsy of Unverricht-Lundborg type (EPM1) is an autosomal recessively inherited childhood-onset neurodegenerative disorder, characterized by myoclonus, seizures, and ataxia. Mutations in the cystatin B gene (CSTB) underlie EPM1. The CSTB-deficient (Cstb (-/-) ) mouse model recapitulates key features of EPM1, including myoclonic seizures. The mice show early microglial activation that precedes seizure onset and neuronal loss and leads to neuroinflammation. We here characterized the inflammatory phenotype of Cstb (-/-) mice in more detail...

The purpose of this study was to clarify the recognizable computed tomography (CT) features of small cell lung carcinoma (SCLC).Contrast enhanced CT scans were reviewed retrospectively for mass location, mediastinal extension, and other concomitant findings in 142 patients with pathologically proven SCLC. SCLC was classified into hilar mass only (type I), hilar mass with ipsilateral mediastinal extension (type II), hilar mass with bilateral mediastinal extension (type III), and peripheral mass (type IV). When mediastinal lymphadenopathy (m-LAP) was indistinguishable from a hilar mass, we defined it as a mediastinal conglomerate mass (m-CM)...

BACKGROUND: Cellular therapies for immunomodulation in vascularized composite allotransplantation (VCA) have gained importance due to their potential minimization of immunosuppression. Adipose-derived mesenchymal stem cells (AD-MSCs) especially have shown encouraging potential. We investigated the influence of timing and frequency of AD-MSC-treatment on immunologic and graft survival as well as graft vasculopathy (GV) outcomes after VCA. METHODS: Lewis (LEW) rats received full-mismatched Brown Norway (BN) rat hindlimb transplants...

Cardiovascular diseases are the leading cause of death worldwide. Literature data indicate that, due to these diseases, approximately 17.5 million people died in 2012. Types of cardiovascular disease include ischemic heart disease, cerebrovascular disease, peripheral vascular disease, congenital heart disease, rheumatic heart disease, cardiomyopathy and arrhythmia. Proper nutrition is an important factor in reducing the risk of cardiovascular events. An interesting element of our diets is spices. For thousands of years, they have been used in the treatment of many diseases: bacterial infections, coughs, colds, and liver diseases...
