SNCA and mTOR Pathway Single Nucleotide Polymorphisms Interact to Modulate the Age at Onset of Parkinson's Disease

Single nucleotide polymorphisms (SNPs) in the α‐synuclein (SNCA) gene are associated with differential risk and age at onset (AAO) of both idiopathic and Leucine‐rich repeat kinase 2 (LRRK2)‐associated Parkinson's disease (PD). Yet potential combinatory or synergistic effects among several modulatory SNPs for PD risk or AAO remain largely underexplored.
A Comparison of Quadriceps Tendon Autograft With Bone-Patellar Tendon-Bone Autograft and Hamstring Tendon Autograft for Primary Anterior Cruciate Ligament Reconstruction: A Systematic Review and Quantitative Synthesis

Objective: There is growing enthusiasm for the increased use of quadriceps tendon (QT) autograft for primary anterior cruciate ligament reconstruction (ACLR). The purpose of this analysis was to synthesize and quantitatively assess the available evidence comparing QT autograft with hamstring tendon (HT) and bone-patellar tendon-bone (BPTB) autografts, regarding functional outcomes, knee stability, anterior knee pain, and revision rates. Data Sources: A search in MEDLINE, EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials for eligible studies up to May 2018 was conducted. Two reviewers selected studies based on inclusion criteria and assessed methodological quality. Outcomes analyzed were anterior knee pain, graft failure rates, knee stability, functional outcomes, and adverse events. Pooled analyses were performed for continuous and dichotomous variables where appropriate. Main Results: Ten studies (1 randomized trial and 9 nonrandomized cohorts) met our inclusion criteria, which included 1398 patients. The analysis showed no statistical difference in anterior knee pain when comparing QT and HT autografts, but a significant difference between QT and BPTB autografts [odds ratio, 0.15 (95% confidence interval, 0.08-0.27); P < 0.001]. There were no differences between all 3 autografts in revision rates, knee stability, and patient-reported functional outcomes. Conclusions: Quadriceps tendon autograft is a suitable graft alternative for primary ACLR, as it achieves good clinical outcomes with a low incidence of anterior knee pain. Given the limited quality of the included studies, there is a need for a well-designed multicenter randomized control trial comparing QT autograft with other primary ACL autografts to confirm our findings. Level of Evidence: Level IV systematic review.
Metabolic Syndrome in Arab Adults with Low Bone Mineral Density

There are discrepancies in the reports on the association of metabolic syndrome (MetS) and its components with bone mineral density (BMD) and hence more population-based studies on this subject are needed. In this context, this observational study was aimed to investigate the association between T-scores of BMD at lumbar L1–L4 and full MetS and its individual components. A total of 1587 participants (84.7% females), >35 years and with risk factors associated with bone loss were recruited from February 2013 to August 2016. BMD was done at L1–L4 using dual-energy X-ray absorptiometry (DXA). T-Scores were calculated. Fasting blood samples and anthropometrics were done at recruitment. Fasting lipid profile and glucose were measured. Screening for full MetS and its components was done according to the National Cholesterol Education Programme Adult Treatment Panel III (NCEP ATP III) criteria. Logistic regression analysis revealed that the odds of having full MetS increased significantly from the lowest T-score tertile to the highest one in both sexes (OR, odd ratio (95% CI, confidence interval) of tertile 2 and 3 at 1.49 (0.8 to 2.8) and 2.46 (1.3 to 4.7), p = 0.02 in males and 1.35 (1.0 to 1.7) and 1.45 (1.1 to1.9), p < 0.01 in females). The odds remained significant even after adjustments with age, body mass index (BMI), and other risk factors associated with bone loss. Among the components of MetS, only central obesity showed a significant positive association with T-score. The study suggests a significant positive association of T-score (spine) with full MetS irrespective of sex, and among the components of MetS this positive association was seen specifically with central obesity.
The Quality and Readability of English Wikipedia Anatomy Articles

Forty anatomy articles were sampled from English Wikipedia and assessed quantitatively and qualitatively. Quantitatively, each article’s edit history was analyzed by Wikipedia X‐tools, references and media were counted manually, and two readability indices were used to evaluate article readability. This analysis revealed that each article was updated 8.3 ± 6.8 times per month, and referenced with 33.5 ± 24.3 sources, such as journal articles and textbooks. Each article contained on average 14.0 ± 7.6 media items. The readability indices including: (1) Flesch–Kincaid Grade Level Readability Test and (2) Flesch Reading Ease Readability Formula demonstrated that the articles had low readability and were more appropriate for college students and above. Qualitatively, the sampled articles were evaluated by experts using a modified DISCERN survey. According to the modified DISCERN, 13 articles (32.5%), 24 articles (60%), 3 articles (7.5%), were rated as “good,” “moderate,” and “poor,” respectively. There were positive correlations between the DISCERN score and the number of edits (r = 0.537), number of editors (r = 0.560), and article length (r = 0.536). Strengths reported by the panel included completeness and coverage in 11 articles (27.5%), anatomical details in 10 articles (25%), and clinical details in 5 articles (12.5%). The panel also noted areas which could be improved, such as providing missing information in 28 articles (70%), inaccuracies in 10 articles (25%), and lack or poor use of images in 17 articles (42.5%). In conclusion, this study revealed that many Wikipedia anatomy articles were difficult to read. Each article’s quality was dependent on edit frequency and article length. Learners and students should be cautious when using Wikipedia articles for anatomy education due to these limitations.
Characteristics of nursing interventions that improve the quality of life of people with chronic diseases. A systematic review with meta-analysis

Purpose The objective of this systematic review was to determine the characteristics of the interventions conducted by nurses that attempt to improve the health related quality of life (HRQoL) of people over 18 years of age with chronic diseases. Methods This systematic review with meta-analysis summarizes 24 studies, conducted in 10 countries, that evaluated HRQoL through the Short-Form Health Survey (SF). Five databases were accessed to find the available studies from December 31st, 2000 to May 22sd, 2017. Selected studies were coded according to the characteristics of the sample and the intervention. A model of random effects was adopted for the overall estimation and to explain the heterogeneity. Results Twenty-four studies were included in the systematic review and meta-analysis providing a sample of 4324 chronic patients aged 63.4 years. Among the 8 subscales and two summary measures that comprise the SF-36, only an overall significant effect size (ES) index was found in the Mental Health Component summary score (ES = 0.14; 95% CI:0.03 − 0.26; I2 = 44.6, p = 0.042) and the Mental Health subscale. This improvement on HRQoL was associated to interventions on “Case Management” and “Treatments and Procedures”, which were based on a theory, were of shorter duration, and had a follow-up period. Conclusions Interventions targeting people with chronic diseases resulted in a slight increase in the HRQoL that was not always significant, which suggests that there is a need for their continuous improvement.
(−)-Epicatechin mitigates radiation-induced intestinal injury and promotes intestinal regeneration via suppressing oxidative stress

Abstract The high radiosensitivity of the intestinal epithelium limits the survival of victims by nuclear accidents or terrorism and limits effective radiotherapy against abdominal malignancies. Recently, we reported that (−)-epicatechin (EC) modulates oxidative stress and exerts neuroprotection. Here, we investigate the protective effects of EC against intestinal damage induced by radiation. The established model is acute moderate but reversible intestinal injury damage. We also set up the injured model of “minigut” ex vivo, which mimic the process of intestinal regeneration in vivo. We found that EC can repress oxidative stress by regulating SOD and MDA levels in serum and intestine tissue. Correspondingly, EC can decrease apoptosis of crypt cells in Lgr5-EGFP-IRES-creERT2 mice after radiation. Further studies demonstrated that EC can promote Nrf2 translocation from cytoplasm to nuclear and then activate the expression of HO1 and NQO1. Interestingly, EC can enhance the activity of intestine stem cells labelled by Lgr5 and promote intestinal epithelium regeneration determined by HE and immunofluorescence staining in vivo and in vitro. We also found that EC can activate the Wnt/β-catenin signal pathway confirmed by TCF/LEF luciferase reporter assay. Together, EC can provide the protective effect on intestine and promote intestinal regeneration after radiation through Nrf2 and Wnt/β-catenin signal pathway.
The Role of Adipose Tissue in the Pathogenesis and Therapeutic Outcomes of Inflammatory Bowel Disease

Though historically regarded as an inert energy store, adipose tissue is a complex endocrine organ, which is increasingly implicated in the pathogenesis of inflammatory bowel disease (IBD). Accumulating evidence points to visceral adipose tissue and specifically to its mesenteric component, or “creeping fat” as impacting on the disease course through its immunomodulatory properties. On the one hand, mesenteric fat acts as a physical barrier to inflammation and is involved in controlling host immune response to translocation of gut bacteria. On the other hand, however, there exists a strong link between visceral fat and complicated course of the disease with unfavorable therapeutic outcomes. Furthermore, “creeping fat” appears to play different roles in different IBD phenotypes, with the greatest pathogenetic contribution probably to an ileal form of Crohn’s disease. In this review, we summarize and discuss the existing literature on the subject and identify high-priority areas for future research. It may be that a better understanding of the role of mesenteric fat in IBD will determine new therapeutic targets and translate into improved clinical outcomes.
The amino acid transporter SLC-36.1 cooperates with PtdIns3P 5-kinase to control phagocytic lysosome reformation

How lysosomes reform following phagolysosomal digestion of apoptotic cells is poorly understood. Gan et al. reveal that the amino acid transporter SLC-36.1 cooperates with PtdIns3P 5-kinase to control phagocygtic lysosome reformation in Caenorhabditis elegans embryos and autophagic lysosome reformation in adult animals.
Gallbladder interstitial Cajal-like cells and gallbladder contractility in patients with cholelithiasis: a prospective study.

INTRODUCTION A reduced number of interstitial Cajal-like cells (ICLCs) in the gallbladder have been proposed to play a role in the pathogenesis of cholelithiasis. Therefore, this prospective study was conducted to investigate the relationship between gallbladder contractility and the number of gallbladder ICLCs in patients with cholelithiasis. MATERIAL AND METHODS Patients admitted to the Department of Hepatobiliary Surgery for cholecystectomy were divided into the cholelithiasis (n = 18) and non-cholelithiasis (n = 8) groups based on their clinical data. Patients' clinical data were collected on admission, and B-mode ultrasonography was performed to assess their gallbladder contractility. The resected gallbladder specimens were fixed, paraffin sections mounted on slides, and the immunofluorescence staining with the anti-human CD-117 and anti-human tryptase antibodies was performed to identify ICLSs and mast cells, respectively. The number of ICLCs was counted in 10 high-power fields (HPFs) randomly. RESULTS Independent sample t-tests revealed differences between the cholelithiasis and non-cholelithiasis groups in the number of ICLCs (mean ± standard deviation: 88.61 ± 28.22 vs. 115.89 ± 27.87 per HPFs, P = 0.032) and gallbladder contractility (43.94% ± 18.50% vs. 61.00% ± 20.50%, P = 0.046). Pearson and Spearman correlation analyses revealed no significant correlation between the number of ICLCs and gallbladder contractility. CONCLUSION The results suggest that the number of gallbladder ICLCs in the wall of the gallbladder of patients with or without cholelithiasis is not a decisive factor affecting gallbladder contractility.
Invasive breast cancer among Alaska Native women in Alaska

ABSTRACT Female breast cancer is the most common cancer diagnosed among Alaska Native (AN) women. We examined characteristics of and trends for female breast cancer among AN women. We assessed descriptive statistics, incidence trends (1969–2014), and cause-specific survival for female breast cancers recorded in the Alaska Native Tumor Registry. Results indicated that the majority of breast cancers among AN were diagnosed among women aged over 50 years, at local stage, and with Hormone receptor (HR)+/Human Epidermal Growth Factor (HER) 2− subtype. Five-year average incidence (95% CI) in the most recent time-period (2009–2014) was 145.0/100,000 (130.4, 159.5)); this was not statistically different from the previous time-period. Survival from breast cancer was high and varied by stage and cancer subtype. Hazard of death was greater among those diagnosed with regional/distant/unknown disease, relative to local disease (HR (95%CI): 4.65 (1.66, 12.98)), and higher among those with HER2−/HR− cancers, relative to those with HER2-/HR+ cancers (HR (95%CI): 6.59 (2.23, 19.49)). This study provides a comprehensive description of breast cancer among AN women, providing new and updated information on clinical and demographic factors, cancer incidence trends, regional variations and breast cancer survival.

Conscientious Objection to Animal Testing: A Preliminary Survey Among Italian Medical and Veterinary Students

The use of animals for educational and research purposes is common in both veterinary and human medicine degree courses, and one that involves important ethical considerations. The aim of this study was to assess the extent of differences between the knowledge and attitudes of veterinary students and medical students on animal bioethics, on alternative strategies and on their right to conscientiously object to animal experimentation. To this end, a questionnaire was completed by 733 students (384 human medicine students (HMS) and 349 veterinary medicine students (VMS)). VMS were more aware than HMS (72.2% and 59.6%, respectively) of the existence of an Italian law on the right to conscientiously object to animal experimentation. However, very few of them had exercised this right. Many VMS (43.3%) felt that animal bioethics courses should be mandatory (only 17.4% of HMS felt the same way). More VMS than HMS (81.7% and 59.1%, respectively) expressed an interest in attending a course on alternatives to animal experimentation. The data suggest the need for appropriate educational interventions, in order to allow students to make choices based on ethical principles. Fostering close collaborations between departments of human medicine and veterinary medicine, for example, through shared study modules, could promote the development of ethical competence as a basic skill of students of both veterinary and human medicine courses.
Characterization of Retinal Structure in ATF6-Associated Achromatopsia

Purpose Mutations in six genes have been associated with achromatopsia (ACHM): CNGA3, CNGB3, PDE6H, PDE6C, GNAT2, and ATF6. ATF6 is the most recent gene to be identified, though thorough phenotyping of this genetic subtype is lacking. Here, we sought to test the hypothesis that ATF6-associated ACHM is a structurally distinct form of congenital ACHM. Methods Seven genetically confirmed subjects from five nonconsanguineous families were recruited. Foveal hypoplasia and the integrity of the ellipsoid zone (EZ) band (a.k.a., IS/OS) were graded from optical coherence tomography (OCT) images. Images of the photoreceptor mosaic were acquired using confocal and nonconfocal split-detection adaptive optics scanning light ophthalmoscopy (AOSLO). Parafoveal cone and rod density values were calculated and compared to published normative data as well as data from two subjects harboring CNGA3 or CNGB3 mutations who were recruited for comparative purposes. Additionally, nonconfocal dark-field AOSLO images of the retinal pigment epithelium were obtained, with quantitative analysis performed in one subject with ATF6-ACHM. Results Foveal hypoplasia was observed in all subjects with ATF6 mutations. Absence of the EZ band within the foveal region (grade 3) or appearance of a hyporeflective zone (grade 4) was seen in all subjects with ATF6 using OCT. There was no evidence of remnant foveal cone structure using confocal AOSLO, although sporadic cone-like structures were seen in nonconfocal split-detection AOSLO. There was a lack of cone structure in the parafovea, in direct contrast to previous reports. Conclusions Our data demonstrate a near absence of cone structure in subjects harboring ATF6 mutations. This implicates ATF6 as having a major role in cone development and suggests that at least a subset of subjects with ATF6-ACHM have markedly fewer cellular targets for cone-directed gene therapies than do subjects with CNGA3- or CNGB3-ACHM.
Endothelin-1-Induced Microvascular ROS and Contractility in Angiotensin-II-Infused Mice Depend on COX and TP Receptors

(1) Background: Angiotensin II (Ang II) and endothelin 1 (ET-1) generate reactive oxygen species (ROS) that can activate cyclooxygenase (COX). However, thromboxane prostanoid receptors (TPRs) are required to increase systemic markers of ROS during Ang II infusion in mice. We hypothesized that COX and TPRs are upstream requirements for the generation of vascular ROS by ET-1. (2) Methods: ET-1-induced vascular contractions and ROS were assessed in mesenteric arterioles from wild type (+/+) and knockout (−/−) of COX1 or TPR mice infused with Ang II (400 ng/kg/min × 14 days) or a vehicle. (3) Results: Ang II infusion appeared to increase microvascular protein expression of endothelin type A receptors (ETARs), TPRs, and COX1 and 2 in COX1 and TPR +/+ mice but not in −/− mice. Ang II infusion increased ET-1-induced vascular contractions and ROS, which were prevented by a blockade of COX1 and 2 in TPR −/− mice. ET-1 increased the activity of aortic nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and decreased superoxide dismutase (SOD) 1, 2, and 3 in Ang-II-infused mice, which were prevented by a blockade of TPRs. (4) Conclusion: Activation of vascular TPRs by COX products are required for ET-1 to increase vascular contractions and ROS generation from NADPH oxidase and reduce ROS metabolism by SOD. These effects require an increase in these systems by prior infusion of Ang II.
Candida yunnanensis sp. nov. and Candida parablackwelliae sp. nov., two yeast species in the Candida albicans/Lodderomyces clade.

During studies on the yeast communities associated with rotting wood in the Xishuangbanna Tropical Rainforest in PR China, four novel yeast strains were found. Phylogenetic analysis based on the concatenated sequences of the D1/D2 domains of the large subunit rRNA gene and the ITS regions showed that these strains represented two novel species in the Candida albicans/Lodderomyces clade. The novel species, represented by strains NYNU 17948 and NYNU 17981, formed a clade with Candida maltosa and Candida baotianmanensis, with 1-1.8% sequence divergence in the D1/D2 domains and 8.9-10% sequence divergence in the ITS regions. The other novel species, represented by NYNU 17105 and NYNU 17763, is most closely related to Candida blackwelliae with 0.7 % sequence divergence in the D1/D2 domains and 6.9 % sequence divergence in the ITS regions. The two novel species could be distinguished from their closest described species in terms of physiological traits. The two novel species are described as Candida yunnanensis sp. nov. (holotype NYNU 17948) and Candida parablackwelliae sp. nov. (holotype NYNU 17763).
User-Centric Solutions for Scholarly Research in the Library

In recent years, the behavior of library users has been undergoing change, as they rely increasingly on web search engines and internet services, rather than libraries, to fulfill their information needs. This paper describes the expectations of such users when looking for information and presents an optimized approach that enables research libraries to provide their patrons with an up-to-date user experience while capitalizing on the unique advantages offered by libraries. Ways of integrating the new solution with the current library environment are discussed, as well as future directions. The Primo discovery and delivery system from Ex Libris serves as an example of such solutions.
Neuroprotective effect of L-arginine in a neonatal rat model of hypoxic-ischemia

Abstract Aim: The aim of the present study is to investigate the neuroprotective effects of l-Arginine (l-arg) in the seven-day-old rat hypoxia-ischemia model. Materials and methods: L-Arginine (n = 10) or saline (n = 8) was administered intraperitoneally to seven-day-old rats before hypoxia-ischemia. In addition, 18 seven-day-old rats were given l-Arginine (n = 10) or saline (n = 8) after hypoxic-ischemic insult. Neuronal apoptosis was investigated by terminal dUDP-biotin nick end-labeling (TUNEL) following three days of recovery. The ratios of right side numerical density to the sum of right and left sides’ numerical densities (right apoptosis index) were calculated for every brain region in rats receiving l-arginine and they were compared with the vehicle groups. Results: Right side apoptosis indexes of the hippocampus (mean ± SD; 35.0 ± 16.1) and striatum (41.9 ± 16.0) were significantly decreased in the l-Arginine post-treatment groups when compared to vehicles (61.0 ± 17.0 and 62.4 ± 27.0 respectively) (p < 0.05). There was no significant difference in the right apoptosis indexes of the cortex between l-Arginine post-treated group and the vehicle group. There were also no significant differences between the right side apoptosis indexes of the l-Arginine pretreatment groups and those of the vehicle group in any of the three regions (p > 0.05). Conclusions: It is concluded that neuronal apoptosis due to hypoxic–ischemic injury may likely to be reduced by post-treatment of l-Arginine in the neonatal rat model and l-Arginine provides a new possibility for neuroprotective strategies based on NO production.
