Therefore, sulfoglycolipid IG20 may become a pharmacological tool for investigating the role of the lipid environment on neuronal excitability, ion channels, neurotransmitter release, synaptic efficacy, and neuronal plasticity. It may also inspire the synthesis of druggable sulfoglycolipids aimed at increasing synaptic plasticity and efficacy in neurodegenerative diseases and traumatic brain-spinal cord injury. The novel synthetic sulfoglycolipid IG20 mimics several physiological effects of endogenous lipids such as regulation of ion channels, Ca(2+) signaling, and exocytosis. This profile may eventually drive enhanced synaptic plasticity and efficacy.
The term "ponticulus posticus" refers to a partial or complete bony arch over the vertebral artery as it crosses the superolateral surface of the posterior arch of the atlas. This anatomical modification is linked to different symptoms, ranging from neckache to headache and migraine. This bony arch may also be incorrectly assessed during orthopaedic surgery for fixation of C1-C2, with consequent risk of damaging the vertebral artery. Its frequency in the general population has been widely analysed by literature in different geographic contexts, but an analysis of the prevalence of such feature in the Italian population is still missing.

A Northern Italian orthodontic sample was analysed to assess the prevalence of ponticulus posticus. Lateral teleradiographies of 221 patients were examined. All the patients underwent lateral cephalometry for odontoiatric purposes and none of them was affected by congenital diseases or skeletal deformities.

In the analysed sample, ponticulus posticus had a prevalence of 7.7% for the complete form, and 9.0% for the incomplete form. Complete and partial forms were observed, respectively, in 8.8 and 11.0% of males, and in 6.9 and 7.7% of females, without statistically significant differences.

The current investigation provided the first data concerning the frequency of ponticulus posticus in Italy further studies are needed to widen the sample, verify possible regional variations and improve the analysis by more advanced radiological examinations such as CT and cone beam CT scans.

A recent study indicated no evidence of the involvement of this variant in Parkinson's disease (PD). Here, we used the genetic and expression data to reinvestigate the potential association between TREM2 and PD susceptibility. In stage 1, using 10 independent studies (N = 89,157; 8787 cases and 80,370 controls), we conducted a subgroup meta-analysis. We identified a significant association between rs75932628 and PD (P = 3.10E-03, odds ratio (OR) = 3.88, 95 % confidence interval (CI) 1.58-9.54) in No-Northern Europe subgroup, and significantly increased PD risks (P = 0.01 for Mann-Whitney test) in No-Northern Europe subgroup than in Northern Europe subgroup. In stage 2, we used the summary results from a large-scale PD genome-wide association study (GWAS; N = 108,990; 13,708 cases and 95,282 controls) to search for other TREM2 variants contributing to PD susceptibility. We identified 14 single-nucleotide polymorphisms (SNPs) associated with PD within 50-kb upstream and downstream range of TREM2. In stage 3, using two brain expression GWAS datasets (N = 773), we identified 6 of the 14 SNPs regulating increased expression of TREM2. In stage 4, using the whole human genome microarray data (N = 50), we further identified significantly increased expression of TREM2 in PD cases compared with controls in human prefrontal cortex. In summary, convergent genetic and expression datasets demonstrate that TREM2 is a potent risk factor for PD and may be a therapeutic target in PD and other neurodegenerative diseases.
Bronchofiberoscopy (BF) is a key tool used in the management of patients with respiratory diseases. Describing factors that contribute to patient anxiety surrounding BF has the potential to influence patient management and willingness to undergo the procedure again in the future if needed.

This study sought to understand what factors influence anxiety and satisfaction experienced by patients undergoing BF under conscious sedation.

This study had a prospective observational character and evaluated 463 consecutive patients undergoing BF. Participants were divided into two groups, those undergoing BF for the first time and those who had undergone the procedure at least once in the past. Data were collected from three questionnaires prepared by the research team.

Patients who had undergone multiple bronchoscopies were more satisfied with their physician's explanation of the procedure (P < 0.0001), had a better understanding of the indications (P < 0.0001) and potential complications (P < 0.0001) of BF and knew what specific procedure was planned (P < 0.001). Patients undergoing BF for the first time experienced anxiety before the procedure more frequently (P < 0.001). No significant difference in satisfaction was observed between patient groups and 89% would agree to BF in the future.

Patients who had previously undergone BF were better prepared for their procedure; however, satisfaction levels after the procedure were similar in both groups. Results suggest that medical staff should target patients who have not undergone BF previously to relieve anxiety.

However, recent research suggests that single-center trials are likely to overestimate treatment effects. There are notable examples in neonatology where results from multi-center trials have contradicted results of single-center studies. In this paper we discuss issues around external generalizability of single-center studies, and methodological issues that may cause bias.
Individuals in recovery from alcohol use disorders (AUDs) frequently continue to smoke cigarettes. The purpose of this study was to examine the relationship between cigarette smoking status and risk of AUD relapse in adults with remitted AUDs among adults in the United States.

Data were drawn from Wave 1 (2001 to 2002) and Wave 2 (2004 to 2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. Analyses included the subsample of respondents who completed both waves of data collection reported a history of alcohol abuse and/or dependence prior to Wave 1 (N=9,134). Relationships between Wave 1 cigarette smoking status (nonsmoker, daily cigarette smoker, and nondaily cigarette smoker) and Wave 2 alcohol use, abuse, and dependence were examined using logistic regression analyses. Analyses were adjusted for Wave 1 demographics; mood, anxiety, and substance use disorders; nicotine dependence; and AUD severity.

Both daily and nondaily cigarette smoking at Wave 1 were significantly associat negative consequences of both substances.
Early detection of cancer is critical and is expected to contribute significantly to the success of cancer therapy and improvement of patient survival rates.

A biocompatible, reconstituted, high-density lipoprotein (rHDL)-based nano-system containing calcium carbonate and near-infrared fluorescence dye (NIRF), methylene blue (MB), was fabricated and characterized by particle size, zeta potential, and morphology observation. The safety profile was confirmed by bovine serum albumin (BSA) challenge assay, hemolysis test, MTT assay, and in vivo long-term toxicity assay. The tumor targetability was assessed by cellular uptake, competitive inhibition experiments, and in vivo imaging assay.

The self-assembled rHDL/MB/CCPs exhibited desirable and homogenous particle size, neutral surface charges, high bovine serum albumin stability, low hemolytic activity, and negligible cytotoxicity in vitro. The results obtained from confocal scanning laser microscopy and flow cytometry indicated that SR-BI coating exerted tumor-targeting function, which induced high and specific cellular uptake of rHDL/MB/CCPs. In vivo investigation in an A549 tumor xenografts-bearing mouse model revealed that rHDL/MB/CCPs possessed strong tumor targetability.

rHDL/MB/CCPs could be a safe tumor-targeting probe for cancer detection.

Limited data are currently available on I nutrition and thyroid disease in lactating women and their breast-fed infants with different I intakes. This study aimed to evaluate I nutrition in both lactating women and their infants and the prevalence of thyroid disease in areas with different levels of I in water. From January to June 2014, a total of 343 healthy lactating women (excluding those taking anti-thyroid drugs or I supplements within a year of the study, consuming seafood at the time of the study or those diagnosed with congenital thyroid disease) from Beihai in Guangxi province and Jiajiazhuang, Yangcheng, Jicun and Pingyao townships in Shanxi province were selected. Compared with the I-sufficient group, median urinary I concentrations in both lactating women and infants as well as breast milk I levels were significantly lower in the I-deficient group (P less then 0·001). The prevalence of thyroid disease in lactating women, particularly subclinical hypothyroidism, was higher in the I-excess group than in the I-sufficient group (P less then 0·05). In areas with excessive water I content, high thyroid peroxidase antibody and high thyroglobulin levels were risk factors for abnormal thyroid-stimulating hormone levels. Our data collectively suggest that excessive I intake potentially causes subclinical hypothyroidism in lactating women. Moreover, enhanced monitoring of I status is important to avoid adverse effects of I deficiency or excess, particularly in susceptible populations such as pregnant or lactating women and infants.An expansion of the distribution of Ostreopsis cf. ovata, a dinoflagellate which produces palytoxin-like compounds, has been reported in recent years. Economical and social interests are affected by blooms, as they are responsible for respiratory and skin problems in humans and may cause damage to marine organisms. FDA approved Drug Library In order to identify the most influential environmental factors that trigger proliferations of O. cf. ovata in the area of the adjacent shallow rocky coast of the Ebro Delta (NW Mediterranean Sea) a three-year survey was performed on the metaphytic microalgae community growing on the macrophytes Jania rubens and Corallina elongata. Small-size diatoms were more abundant than dinoflagellates; O. cf. ovata was identified as the only species present from the genus. Seawater temperature was the primary driver defining the ecological niche of O. cf. ovata. Freshwater and groundwater fluxes were more pronounced in southern than in northern sites, which may have resulted in a distinct O. cf. ovata spatial distribution, with the highest records of abundance and more frequent blooms in the north.
