Cerebellar herniation after lumbar puncture in galactosemic newborn.

Cerebral edema resulting in elevated intracranial pressure is a well-known complication of galactosemia. Lumbar puncture was performed for the diagnosis of clinically suspected bacterial meningitis. Herniation of cerebral tissue through the foramen magnum is not a common problem in neonatal intensive care units because of the open fontanelle in infants.

Assessment of red cell distribution width (RDW) in patients with coronary artery ectasia.

Objectives: Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries. Red cell distribution width (RDW) is a measure of heterogeneity in the size of red blood cell. In this study, we aimed to investigate RDW levels in patients with CAE.

Impaired aortic elastic properties in patients with chronic graft-versus-host disease.

Objectives: Graft-versus-host disease (GVHD), which develops as a result of the immunologic response that donor T-lymphocytes generate against host tissue following hematopoietic stem cell transplantation (HSCT), is the leading cause of morbidity and mortality in these patients. The aim of this study is the investigate relation between aortic wall stiffness and duration of the disease in patients with chronic GVHD.

Methods: The study population included 32 patients (18 men; mean age, 36.

The association of serum uric acid levels on coronary flow in patients with STEMI undergoing primary PCI.

Objective: Uric acid has been shown as a predictor and an independent risk factor for coronary heart disease, but little is known regarding the association of uric acid levels with coronary blood flow in STEMI. We hypothesized that elevated uric acid levels would be associated with impaired flow and perfusion in the setting of STEMI treated with primary PCI.

Methods: Two hundred and eighty nine patients with STEMI who treated primary PCI were enrolled to study.

Penicillin induced epileptiform activity and EEG spectrum analysis of BDNF heterozygous mice: an in vivo electrophysiological study.

Brain-derived neurotrophic factor (BDNF) heterozygous mice (BDNF (+/-)) kindle slowly and have a higher seizure threshold. However, BDNF (+/-) mice exhibit reduced cortical inhibition and disrupted balance of excitation/inhibition synaptic transmission. We investigated penicillin-induced focal cortical epileptiform activity and electroencephalogram (EEG) spectral power of BDNF (+/-) mice, by using electrocorticogram (ECoG) recordings.

Hematologic parameters and angiographic progression of coronary atherosclerosis.

Hematologic parameters have prognostic importance in cardiovascular disease. However, the relation between atherosclerosis progression and hematologic parameters is not well defined. A total of 394 patients requiring repeat coronary angiography were included in the study.

Porous coordination polymer hybrid device with quartz oscillator: effect of crystal size on sorption kinetics.

A new strategy to synthesize monodispersed porous coordination polymer (PCP) nanocrystals at room temperature was developed and utilized for the formation of PCP thin films on gold substrates with fine control over the crystal sizes using the coordination modulation method. Hybridization of these PCP thin films with an environment-controlled quartz crystal microbalance system allowed determining the adsorption properties for organic vapors (methanol and hexane). In the case of high sensitivity (at the low-concentration dosing of analytes), the sensor response depended on the crystal size but not on the type of analyte.

Diagnosis and treatment of depression in older community-dwelling adults: 1992-2005.

Objective: To examine evolving patterns of depression diagnosis and treatment in older U.S. adults in the era of newer-generation antidepressants.

Fundamental and functional aspects of mesoscopic architectures with examples in physics, cell biology, and chemistry.

How small can a macroscopic object be made without losing its intended function? Obviously, the smallest possible size is determined by the size of an atom, but it is not so obvious how many atoms are required to assemble an object so small, and yet that performs the same function as its macroscopic counterpart. In this review, we are concerned with objects of intermediate nature, lying between the microscopic and the macroscopic world. In physics and chemistry literature, this regime in-between is often called mesoscopic, and is known to bear interesting and counterintuitive features.

Aortic and coronary artery dissection during percutaneous coronary intervention: a case report and review article.

Coronary artery dissection is an uncommon but potentially serious complication in percutaneous coronary interventions. We treated a 53-year-old female patient with right coronary spasm, which was misdiagnosed as a coronary lesion. The coronary spasm resolved with nitrate administration, but proximal coronary dissection developed during angiography.

Design: Annual cross-sectional analysis of merged resident assessment data from the Minimum Data Set (MDS) and facility characteristics from the Online Survey Certification and Reporting data.

Setting: Nursing homes in eight states (5,445 facilities).

Design of neo-glycoconjugates that target the mannose receptor and enhance TLR-independent cross-presentation and Th1 polarization.

Cross-presentation is an important mechanism by which DCs present exogenous antigens on MHC-I molecules, and activate CD8(+) T cells, cells that are crucial for the elimination of tumors. We investigated the feasibility of exploiting the capacity of the mannose receptor (MR) to improve both cross-presentation of tumor antigens and Th polarization, processes that are pivotal for the anti-tumor potency of cytotoxic T cells. To this end, we selected two glycan ligands of the MR, 3-sulfo-Lewis(A) and tri-GlcNAc (N-acetylglucosamine), to conjugate to the model antigen OVA and assessed in vitro the effect on antigen presentation and Th differentiation.

DC-SIGN mediated antigen-targeting using glycan-modified liposomes: formulation considerations.

Dendritic cells (DCs) are key antigen presenting cells that have the unique ability to present antigens on MHC molecules, which can lead to either priming or suppression of T cell mediated immune responses. C-type lectin receptors expressed by DCs are involved in antigen uptake and presentation through recognition of carbohydrate structures on antigens. Here we have explored the feasibility of modification of liposomes with glycans for targeting purposes to boost immune responses.

The relationship between renal functions and thrombolysis in myocardial infarction frame count in patients with slow coronary flow.

We investigated the relationship between renal function and coronary thrombolysis in myocardial infarction frame count (TFC) in patients with slow coronary flow (SCF). The patient group was composed of 34 patients with SCF. The control group was made up of 34 well-matched individuals who have normal SCF in their coronary arteries.

Incidence, clinical characteristics, and 4-year follow-up of patients with isolated myocardial bridge: a retrospective, single-center, epidemiologic, coronary arteriographic follow-up study in southern Turkey.

Introduction: Myocardial bridge is a rare coronary anomaly that is generally considered to be benign. The true incidence and long-term prognosis are still under debate. Therefore, we investigated the prevalence and prognosis of patients with isolated myocardial bridge in our center.

Two-year outcome of Turkish patients treated with Zotarolimus versus Paclitaxel eluting stents in an unselected population with coronary artery disease in the real world: a prospective non-randomized registry in southern Turkey.

Background: Our purpose was to investigate the clinical outcomes of Zotarolimus- and Paclitaxel-eluting stents in Turkish patients with coronary artery disease (CAD). In general, the outcome of drug-eluting stent (DES) placement has a proven efficacy in randomized trials. However, the difference in efficacy between the Zotarolimus and Paclitaxel-eluting stents in unselected Turkish patients is controversial.

Left ventricular strain and strain rate echocardiography analysis in patients with total and subtotal occlusion in the infarct-related left anterior descending artery.

Background: Numerous studies show that percutaneous coronary intervention has no clinical benefit in patients with total occlusion. Both regional and global left ventricle (LV) functions may be evaluated in detail by strain (S) and strain rate (SR) echocardiography. The purpose of this study is to evaluate whether S and SR echocardiography may be used to determine the total occlusion.

Nomadic enhancers: tissue-specific cis-regulatory elements of yellow have divergent genomic positions among Drosophila species.

cis-regulatory DNA sequences known as enhancers control gene expression in space and time. They are central to metazoan development and are often responsible for changes in gene regulation that contribute to phenotypic evolution. Here, we examine the sequence, function, and genomic location of enhancers controlling tissue- and cell-type specific expression of the yellow gene in six Drosophila species.

Acute effects of passive smoking on left ventricular systolic and diastolic function in healthy volunteers.

Background: The aim of this study was to investigate the acute effects of passive smoking on left ventricular (LV) function in healthy volunteers.

Methods: Sixty-one healthy nonsmoking volunteers were enrolled in this study. LV M-mode, two-dimensional, conventional Doppler, and color tissue Doppler echocardiography were performed, and carboxyhemoglobin (COHb) levels were obtained from subjects before and immediately after exposure to passive smoking for 30 min in a smoking room.

Effect of long-term and high-dose allopurinol therapy on endothelial function in normotensive diabetic patients.

Objectives: Endothelial dysfunction is a well known risk factor for atherosclerosis. Uric acid levels are associated with endothelial dysfunction and atherosclerosis even if in physiological range. Xanthine oxidase inhibition with allopurinol decreases uric acid levels and oxidative stress and improves endothelial function.

CEP152 is a genome maintenance protein disrupted in Seckel syndrome.

Functional impairment of DNA damage response pathways leads to increased genomic instability. Here we describe the centrosomal protein CEP152 as a new regulator of genomic integrity and cellular response to DNA damage. Using homozygosity mapping and exome sequencing, we identified CEP152 mutations in Seckel syndrome and showed that impaired CEP152 function leads to accumulation of genomic defects resulting from replicative stress through enhanced activation of ATM signaling and increased H2AX phosphorylation.

Intravenous N-acetylcysteine plus high-dose hydration versus high-dose hydration and standard hydration for the prevention of contrast-induced nephropathy: CASIS--a multicenter prospective controlled trial.

Background: Contrast-induced nephropathy (CIN) is a leading cause of acute renal failure and affects mortality and morbidity. We investigated the efficacy of prophylactic intravenous (IV) N-acetylcysteine (NAC) and hydration for the prevention of CIN in patients with mild to moderate renal dysfunction who are undergoing coronary angiography and/or percutaneous coronary intervention (PCI).

Methods: A total of 220 patients who had mild to moderate renal dysfunction with serum creatinine (SCr) ≥ 1.
