Dianne Pulte, Lina Jansen, Hermann Brenner
BACKGROUND: Rectal cancer (RC) is a common malignancy with a substantial mortality but good survival for patients with optimally treated nonmetastatic disease. Lack of insurance may compromise access to care and therefore compromise survival. Here, we examine RC survival by insurance type. METHODS: Data from the Surveillance, Epidemiology, and End Results database were used to determine 1- to 3-year survival for patients with RC by insurance type (Medicaid, uninsured, other insurance)...

Rationale: Familial sinus node and atrioventricular (AV) conduction dysfunction is a rare disorder that leads to paroxysmal dizziness, fatigue and syncope due to a temporarily or permanent reduced heart rate. To date, only a few genes for familial sinus and/or AV conduction dysfunction are known and the majority of cases remain etiologically unresolved. Objective: We aim to identify the disease gene in a large three-generation family (n=25) with autosomal dominant sinus node dysfunction (SND) and AV block (AVB) and to characterise the mutation-related pathomechanisms in familial SND+AVB...

Mycobacterium tuberculosis can interfere with host immune response and escape clearance through its specific antigens. M. tuberculosis Rv1987 encoded by region of difference (RD)-2 gene is a secretory protein with immunogenic potency. Here, we investigated the impact of Rv1987 on host cytokine responses and T cell polarization in mouse aerosol model. A recombinant M. smegmatis mc(2)155 strain that overexpressed Rv1987 protein (named MS1987) was constructed and used to infect C57BL/6 mice. The mc(2)155 harbored the empty vector (named MSVec) was as a control...

BACKGROUND: We recently constructed a Bacillus subtilis strain (CCTCC M 2016536) from which we had deleted the srfC, spoIIAC, nprE, aprE and amyE genes. This strain is capable of robust recombinant protein production and amenable to high-cell-density fermentation. Because the promoter is among the factors that influence the production of target proteins, optimization of the initial promoter, PamyQ from Bacillus amyloliquefaciens, should improve protein expression using this strain. This study was undertaken to develop a new, high-level expression system in B...

This review aims to empower general neurologists to provide better informed person-centred advice on sudden unexpected death in epilepsy (SUDEP) to people with epilepsy in order to help keep them safe. Past and present evidence is consolidated in order to inform readers about SUDEP, and up-to-date insights into the epidemiology, diagnostic classification, pathophysiology, risk factors, influence of co-morbidity, and importance of sensitive person-centred communication are outlined. This review provides "fingertip" information to the practicing neurologist with regards to identifying and communicating risks for SUDEP and suggests practical measures for managing these risks in partnership with the patient...

NLRC (the nucleotide-oligomerization domain (NOD)-like receptor subfamily C) consists of teleost-specific NLRs (NOD-like receptors) and plays pivotal roles in microbial recognition and regulation of innate immune response. In this study, we cloned and characterized a NLRC3-like gene (MamNLRC3-like) from blunt snout bream (Megalobrama amblycephala) by using the quantitative real-time PCR method, and analyzed the correlation between its polymorphisms and resistance to Aeromonas hydrophila infection. The full length cDNA of MamNLRC3-like was 2863 bp, with a 5'-UTR of 169 bp, ORF of 2301 bp and 3'-UTR of 393 bp, encoding 766 amino acid residues...

Primary angle-closure glaucoma (PACG) is a severe chronic neurodegenerative disease in Asia. Identification of important metabolites associated with PACG is crucial for early intervention and advancing knowledge of the disease mechanism. We applied gas chromatography-mass spectrometry (GC-MS) for targeted metabolomic analysis on serum samples from thirty-eight newly diagnosed PACG patients and forty-eight controls. Palmitoleic acid (PA), linoleic acid (LA), gamma-linolenic acid (GLA) and arachidonic acid (ARA) were identified as important metabolites associated with PACG...

Low adherence to secondary prevention medications (ATM) of patients after acute coronary syndrome (ACS) is associated with poor clinical outcomes. However, literature provides limited data on assessment of ATM and risks associated with poor in Chinese patients with ACS. In the current work, ATM was assessed in consecutively recruited patients with ACS in Tongji Hospital from November 5, 2013 to December 31, 2014. A total of 2126 patients were classified under low adherence (proportion of days covered (PDC) C< 50%) and high adherence (PDC>50%) groups based on their performance after discharge...

BACKGROUND: The trans-frontal-sinus-subcranial approach (TFSSA) allows for direct exposure and removal of olfactory groove meningiomas (OGMs), without any brain retraction. Compared to other skull base approaches (like fronto-orbito-basal, transbasal, subcranial, fronto-orbito-zygomatic and one-and-half approach), it could offer the same advantages but it is less invasive. OBJECT: We report the results in a series of 21 consecutive patients harboring OGMs and operated through TFSSA, in order to propose a viable alternative approach...

Survival for patients with acute myeloblastic leukemia (AML) has increased during the past two decades. However, socioeconomic disparities may affect survival for some patient populations. We examine survival by insurance type for patients with AML. Using data from the Surveillance, Epidemiology, and End Results database we estimated survival according to insurance status (no insurance, Medicaid, and other insurance) for patients diagnosed with AML in the United States in 2007-2013. One, 3-, and 5-year survival was lower for patients with no insurance and Medicaid than for patients with other insurance...

PURPOSE OF REVIEW: Wnt signaling plays a crucial role during embryogenesis. In an adult, Wnt is mainly associated to cellular proliferation and differentiation mechanisms. Recent data suggest that Wnt signaling is involved in the pathophysiology of atherosclerosis. However, the roles of Wnt signaling pathways in the vessel wall are poorly understood. This review outlines recent discoveries in understanding the role of Wnt pathways in healthy and atherosclerotic vessels. RECENT FINDINGS: In the last years, the involvement of both canonical and noncanonical Wnt pathways in the development of atherosclerotic lesions has been recognized...

Here we present the results of a multiple organizational level analysis conceived to identify acclimative/adaptive strategies exhibited by the seagrass Posidonia oceanica to the daily fluctuations in the light environment, at contrasting depths. We assessed changes in photophysiological parameters, leaf respiration, pigments, and protein and mRNA expression levels. The results show that the diel oscillations of P. oceanica photophysiological and respiratory responses were related to transcripts and proteins expression of the genes involved in those processes and that there was a response asynchrony between shallow and deep plants probably caused by the strong differences in the light environment...

OBJECTIVE: Circulating microparticles (cMPs) are phospholipid-rich vesicles released from cells when activated or injured, and contribute to the formation of intracoronary thrombi. Tissue factor (TF, CD142) is the main trigger of fibrin formation and TF-carrying cMPs are considered one of the most procoagulant cMPs. Similar types of atherosclerotic lesions may lead to different types of AMI, although the mechanisms behind are unresolved. Therefore, we aimed to investigate the phenotype of cMPs found in plasma of ACS patients and its relation to AMI severity and thrombotic burden...

DNA oxidation damage has been regarded as one of the possible mechanisms for the hepatic carcinogenesis of dioxin-like compounds (DLCs). In this study, we evaluated the toxic equivalency factor (TEF) from the standpoint of induced DNA oxidation products and their relationship to toxicity and carcinogenicity. Nine DNA oxidation products were analyzed in the liver of female Sprague-Dawley rats exposed to 2,3,7,8-tetrachlorodibenzo-pdioxin (TCDD) alone or the tertiary mixture of TCDD, 3,3',4,4',5-pentachlorobiphenyl (PCB 126), and 2,3,4,7,8-pentachlorodibenzofuran (PeCDF) by gavage for 14, 31, and 53 weeks (5 days/week) by LC-MS/MS: 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dGuo); 1,N(6)-etheno-2'-deoxyadenosine (1,N(6)-εdAdo); N(2),3-ethenoguanine (N(2),3-εG); 7-(2-oxoethly)guanine (7-OEG); 1,N(2)-etheno-2'-deoxyguanosine (1,N(2)-εdGuo); malondialdehyde (M1dGuo); acrolein (AcrdGuo); crotonaldehyde (CrdGuo); and 4-hydroxynonenal (HNEdGuo) derived 2'-deoxyguanosine adducts...

Inhalational general anesthetics, such as sevoflurane and isoflurane, modulate a subset of brain Kv1 potassium channels. However, the Kv1.2 channel is resistant to propofol, a commonly used intravenous alkylphenol anesthetic. We hypothesize that propofol binds to a presumed pocket involving the channel's S4-S5 linker, but functional transduction is poor and, therefore, propofol efficacy is low. To test this hypothesis, we used a photoactive propofol analog (meta-aziPropofol = AziPm) to directly probe binding and electrophysiological and mutational analyses in Xenopus oocytes to probe function...
