Published: May 2024

Personal Learning Environment (PLE) enables a knowledge-based, learner-centered lifelong learning which could be successfully integrated with formal education when taking educators’ supervision into consideration. But do learners’ preferred Learning Styles matter in PLE? To investigate the relationship among learners’ Learning Styles, learning outcomes and satisfaction towards the PLE platform, the study constructed and applied a supervised-PLE-IELTS platform. 57 sophomores majored in Business in Wenzhou University took part in a 16-week project. Data were collected by Honey and Mumford’s Learning Styles questionnaire for the Learning Styles, post-test of IELTS reading, listening and vocabulary for the cognitive learning outcomes, and Distance Education Learning Environments Survey (DELES) for the satisfaction towards the PLE platform. The results showed: (1) Learning Styles have positive relationship with the cognitive learning achievements in PLE; (2) Learning Styles had no direct effect on satisfaction, and learners of all Learning Styles enjoyed PLE-IELTS platform; and (3) learners who spent more time on PLE platform achieved better cognitive learning outcomes. The paper shed light on the future construction of supervised-PLEs.

The control group comprised 40 fertile men, aged 25 to 45 years, who had experienced both primary and secondary fecundity for at least twelve months. The Patients Cases group, consisting of sixty infertile males aged between 22 and 46 years, was categorized into two subgroups based on the type of infertility. There were forty-six guys who were classified as main infertility. There were a total of fourteen men who experienced secondary infertility. Male participants who are reproductive age, normal seminal analysis which is healthy and have a child as a Control group (Fertile men). Name of patient, sample number, Age (years), Education, housing area, Type of work, height, weight, Smoking, chronic diseases, History of surgery, Primary infertility, Secondary infertility, Sperm count, Sperm motility and Sperm morphology. Detection of CMV in semen plasma by CMV ELISA kit and detection of HHV 6 in semen plasma by HHV 6 ELISA kit. Result; The results showed that there was no statistical significance in age between the two groups. They also showed that there was statistical significance in smoking, type of infertility, and duration of infertility. The results showed statistical significance in the results for herpes and cytomegalovirus. There is also no statistical significance regarding the number of cases of cytomegalovirus infection according to age. On the contrary, there was statistical significance regarding age in herpes. The results also indicated that there was statistical evidence in the sperm analysis between the two groups. Conclusions; The statistical evidence between the two groups in the number of infection cases for all groups or by age indicates the role of viral infections in causing infertility in men.

Published: June 2024

The current study aimed to determine the prevalence of intestinal parasites among children from newborns to ten years of age in different areas affiliated with the Shatra district in Dhi Qar Governorate in southern Iraq, as these areas suffer from poor health and living services in addition to a lack of awareness and interest in personal and health hygiene. The study was designed by taking 100 A random sample from different areas. The results were 25% of healthy children, while 75% were infected. The widespread infections were with the parasites Giardia lamblia and Entamoeba histolytica.
The results confirmed that most of the infected children were between two and four years of age, in addition to the fact that the most common infections were the combined infections of the Entamoeba parasite and Giardia for the same infected people, with a very high rate of up to 56%, while the infection of children with the Entamoeba parasite alone was 18.7% and Giardia alone was 25.3% in addition. The percentage of females is 65% while the percentage of males is 35% in parasitic infections and The infection rate in the countryside was higher than the infection rate in cities, as the infection rate in the countryside was (55%) and in the cities (45%).
Kirjailijan todistus juutalaisten joukkomurhista Kiovassa 1941–1943
Authors: Laitila Teuvo 
Published: June 2024

Artikkelissa tarkastellaan holokaustin ja antisemitismin käsitteen tulkin-toja Anatoli Kuznetsovin romaanissa Babi Jar. Teoksen sensuroitu versio ilmestyi Neuvostoliitossa vuonna 1967. Sensuroimaton versio julkaistiin kolme vuotta myöhemmin englanniksi ja venäjäksi. Kirjailija oli tuolloin jo loikannut Britanniaan. Neuvostoliitossa holokausti yhdistettiin neuvostokansalaisten surmaamiseen toisessa maailmansodassa.Natsi-Saksa ei tulkinnan mukaan pyrkinyt surmaamaan juutalaisia vaan sosialistisen valtion siviilejä. Luokkayhteiskunnan lakkauttaneessa Neuvostoliitossa ei valtion väitteen mukaan ollut antisemitismiä, koska se oli kapitalistiseen yhteiskuntaan kuuluvan luokkavihan muoto. Kuznetsovin sensuroimattoman version keskeinen idea oli verrata Babi Jarin rotkossa Kiovassa tapahtunutta juutalaisten joukkomurhaa, holokaustin osaa, Stalinin 1930-luvulla aiheuttamaan nälänhätään, holodomoriin, sekä poliittisiin ”puhdistuksiin”. Tavoitteena oli osoittaa, että Neuvostoliitto ja Saksa olivat molemmat diktatuurisia ”tappa-misjärjestelmiä”. Sensuuri poisti tämän vertailevan ulottuvuuden ja korosti siten Babi Jarin joukkomurhia juutalaisten, ei neuvostokansalaisten, tappamisena. Antisemitismi, jokaneuvostotulkinnassa irrotettiin holokaustista, jäi molemmissa teoksen versioissa vähälle huomiolle. Sensuuri ja Kuznetsov olivat näin uskollisia Marxille, joka harvoissa aihetta käsitelleissä teksteissään yhdisti juutalaisuuden ja kapitalismin ja määritteli antisemitismin antikapitalismiksi
Implementing intersectoral alcohol policies at the local level: A case study from Santiago, Chile, 2014-2017
Authors: Peña Sebastián , Espinoza Francisco , Sierralta Paula 
Published: May 2024

Background. Local governments have a crucial role to play in alcohol control policies. However, there is a lack of descriptions of comprehensive intersectoral alcohol control strategies led by them. The study describes the experience of developing and implementing an intersectoral alcohol strategy in the Municipality of Santiago, Chile, between 2014-2017.

Methods. We used a case study design. We used data from municipal documents, including reports from fee agreements, official sources of information, municipal service calls and police records, georeferenced data on alcohol outlets and photographs of storefront signs. We used data from interviews with community stakeholders and municipal workers conducted during the study period.

Results. The first stage (2014-2015) consisted of using local evidence to build political will. The main activities were introducing screening and brief alcohol interventions in high schools, supporting a public consultation on reducing the opening hours of liquor stores, and introducing economic incentives to reduce street-level alcohol marketing. The second stage (2015-2017) included a community-action pilot plan and the development and implementation of an intersectoral alcohol control plan involving twelve municipal departments. Activities aimed at reducing the number of alcohol outlets, enhancing transparency on alcohol licensing procedures, and improving the quality of brief interventions. The strategy implemented actions in nine out of ten WHO Alcohol Policy domains.

Conclusions. The experience of Santiago demonstrates the untapped potential for alcohol control at the local level. Political will, local evidence, sharing common goals and medium-term budget frameworks are important facilitators of comprehensive intersectoral alcohol interventions.
Autism and cancer risk
Authors: Crespi B. 
Published: August 2011

AbstractA literature review was conducted on the genetic and developmental bases of autism in relation to genes and pathways associated with cancer risk. Convergent lines of evidence from four types of analysis: (1) recent theoretical studies on the causes of autism, (2) epidemiological studies, (3) genetic analyses linking autism with mutations in tumor suppressor genes and other cancer‐associated genes and pathways, and (4) contrasts with schizophrenia, Parkinson's, and Alzheimer's disease indicate that autism may involve altered cancer risk. This evidence should motivate further epidemiological studies, and it provides useful insights into the nature of the genetic, epigenetic, and environmental factors underlying the etiologies of autism, other neurological conditions, and carcinogenesis.

Published: August 2011

AbstractThis article presents a Matlab‐based educational software developed at Aristotle University of Thessaloniki in Greece, in order to familiarize students and young engineers with fundamental concepts of structural dynamics and, in particular, soil–structure interaction problems. This user‐friendly educational tool aims to assist the students in comprehending the nature of this complex phenomenon and the role played by the physical parameters involved, while increasing their awareness of the potential impact of neglecting soil flexibility during seismic design of reinforced concrete (RC) buildings. This software is also used as a case study for teaching the development of civil engineering‐oriented applications in Matlab within a course where all the relevant material is provided online. Two demonstration examples are comparatively assessed to illustrate the applicability of the software and justify the necessity of its implementation in class, while the integration of the software in the curriculum as well as students' feedback is also discussed. © 2011 Wiley Periodicals, Inc.

Abstract
Triclosan has been commonly used as an antimicrobial and disinfectant agent. Distribution between water and sediment plays a key role in its occurrence, transfer, and fate in the aquatic environment. Sorption of triclosan onto sediments and the effect of the biosurfactant rhamnolipid on distribution were studied in the present work. Batch equilibrium experiments were performed on three different sediments, with a wide triclosan concentration range. S-shaped equations can be used to describe the sorption behavior when triclosan concentration is relative high (50–250 µg · g−1). The Pearl River, China (PR), sediment, which has the largest cumulative volume of pores, appeared to have great capability for continuously capturing triclosan. In the lower concentration range (10–150 µg · g−1) assays, linear and Freundlich equations fitted the sorption isotherm data well. The pH value of sediment appeared to have a significant influence on sorption of low triclosan concentrations. Formation of rhamnolipid micelle remarkably decreased the sediment–water distribution ratio, Kd*. Evaluation of the distribution efficiency, E, suggested that pores of sediment might have played a role in triclosan distribution, whereas sediment organic matter bound triclosan and reduced solubilization of triclosan. Rhamnolipid appears to be a good sorbent for triclosan. The findings of the present study suggest that, to understand the sorption and distribution of triclosan fully, studies should be carried out over a relatively broad concentration range. Environ.

Eicosapentaenoic Acid and Docosahexaenoic Acid Regulate Modified LDL Uptake and Macropinocytosis in Human Macrophages

Published: August 2011

AbstractThere is evidence that long chain n‐3 PUFA (such as from fish oils) provide atheroprotection through, in part, changes in macrophage function although it has not been fully determined whether these n‐3 PUFA target cellular mechanisms that control macrophage foam cell formation. Therefore, we investigated whether the n‐3 PUFA, EPA and DHA, modulate modified low‐density lipoprotein (LDL) uptake by human macrophages. The uptake of fluorophore labeled acetylated LDL (AcLDL) and/or oxidized LDL (OxLDL) by THP‐1 macrophages and primary human monocyte‐derived macrophages were measured by flow cytometry following co‐incubation with EPA or DHA in vitro. DHA inhibited both AcLDL and OxLDL uptake in human macrophages whilst EPA reduced AcLDL and increased OxLDL uptake. These effects were only partly explained by changes in the mRNA and protein expression of key scavenger receptors, such as CD36 and scavenger receptor‐A, in these cells suggesting the involvement of a scavenger receptor‐independent mechanism. EPA and DHA inhibited macropinocytosis, as measured by Lucifer Yellow uptake, in human macrophages and attenuated the expression of Syndecan‐4, which has been implicated in the uptake of other modified forms of LDL. EPA and DHA reduced modified LDL uptake by human macrophages through a mechanism that is in part scavenger receptor‐independent and may involve inhibition of macropinocytosis and Syndecan‐4 expression. This suggests that both EPA and DHA are capable of regulating macrophage foam cell formation and adds to the evidence describing an atheroprotective role for n‐3 PUFA, implicating them as potential therapeutic agents for the treatment of clinical atherosclerosis.

AbstractCetyl octanoate, a wax ester of 24 carbons, is widely used in the cosmetic industry as a base oil. The current work focuses on lipase‐catalyzed synthesis of cetyl octanoate in supercritical carbon dioxide (SC‐CO2) by esterification of cetyl alcohol and octanoic acid. Three immobilized lipases were screened, and 15 reaction conditions were tested in order to find the combination for maximal yield. The results showed that Novozym® 435 was the best catalyst for the synthesis, and a reaction time of 20 min was adequate for a maximal yield. Response surface methodology (RSM) with a 3‐factor‐3‐level Box‐Behnken design was employed to evaluate the effects of synthesis parameters, including reaction temperature (35–75 °C), pressure (8.27–12.41 MPa), and enzyme amount (5–15% wt of cetyl alcohol). A model for the synthesis was developed and the optimum conditions could be predicted to be reaction pressure of 10.22 MPa, reaction temperature of 63.70 °C, and enzyme amount of 11.20%. An experiment was performed under this optimum condition and a yield of 99.5% was obtained. This experimental yield correlated well with the predicted value of yield (97.6%). We concluded that, in a SC‐CO2 system, nearly 100% molar conversion of cetyl octanoate could be obtained by immobilized Novozym® 435 in a short reaction time (20 min) under the predicted optimal conditions.

AbstractObjectiveTo study the efficacy and safety of phosphatidylserine (PS) containing Omega3 long-chain polyunsaturated fatty acids attached to its backbone (PS-Omega3) in reducing attention-deficit/ hyperactivity disorder (ADHD) symptoms in children.MethodA 15-week, double-blind, placebo-controlled phase followed by an open-label extension of additional 15 weeks. Two hundred ADHD children were randomized to receive either PS-Omega3 or placebo, out of them, 150 children continued into the extension. Efficacy was assessed using Conners’ parent and teacher rating scales (CRS-P,T), Strengths and Difficulties Questionnaire (SDQ), and Child Health Questionnaire (CHQ). Safety evaluation included adverse events monitoring.ResultsThe key finding of the double-blind phase was the significant reduction in the Global:Restless/impulsive subscale of CRS-P and the significant improvement in Parent impact-emotional (PE) subscale of the CHQ, both in the PS-Omega3 group. Exploratory subgroup analysis of children with a more pronounced hyperactive/impulsive behavior, as well as mood and behavior-dysregulation, revealed a significant reduction in the ADHD-Index and hyperactive components. Data from the open-label extension indicated sustained efficacy for children who continued to receive PS-Omega3. Children that switched to PS-Omega3 treatment from placebo showed a significant reduction in subscales scores of both CRS-P and the CRS-T, as compare to baseline scores. The treatment was well tolerated.ConclusionsThe results of this 30-week study suggest that PS-Omega3 may reduce ADHD symptoms in children. Preliminary analysis suggests that this treatment may be especially effective in a subgroup of hyperactive-impulsive, emotionally and behaviorally-dysregulated ADHD children.
Reliability of an Upper-Limb Assessment Tool for Acute Neurological Patients
Authors: Downie Sharon 
Published: August 2011

Objective Occupational therapists working within acute neurosciences assume a primary role in the identification of upper-limb impairments, and to achieve this, they require measurement tools, which are sensitive to small changes in patient function. The purpose of this study was to examine the psychometric properties of a newly developed upper-limb assessment tool (ULAT) for acute neurological patients. Methods Using a prospective study design, 30 patients with a confirmed neurological diagnosis completed the ULAT. Nonparametric statistics were then completed to examine the ULAT's reliability. Results The ULAT exhibited strong intra- and inter-rater reliability and acceptable internal consistency across patients with various neurological diagnoses. Conclusion Evidence of the ULAT's robust reliability supports its ongoing refinement and potential use in acute care neurological settings by occupational therapists.

Published: August 2011

AbstractMany paleoclimate and landscape change studies in the American Midwest have focused on the Late Glacial and early Holocene time periods (~ 16–11 ka), but little work has addressed landscape change in this area between the Last Glacial Maximum and the Late Glacial (~ 22–16 ka). Sediment cores were collected from 29 new lake and bog sites in Ohio and Indiana to address this gap. The basal radiocarbon dates from these cores show that initial ice retreat from the maximal last-glacial ice extent occurred by 22 ka, and numerous sites that are ~ 100 km inside this limit were exposed by 18.9 ka. Post-glacial environmental changes were identified as stratigraphic or biologic changes in select cores. The strongest signal occurs between 18.5 and 14.6 ka. These Midwestern events correspond with evidence to the northeast, suggesting that initial deglaciation of the ice sheet, and ensuing environmental changes, were episodic and rapid. Significantly, these changes predate the onset of the Bølling postglacial warming (14.8 ka) as recorded by the Greenland ice cores. Thus, deglaciation and landscape change around the southern margins of the Laurentide Ice Sheet happened ~ 7 ka before postglacial changes were felt in central Greenland.

Published: August 2011

AbstractMotivation: Motifs in DNA sequences often appear in degenerate form, so there has been an increased interest in computational algorithms for weak motif discovery. Probabilistic algorithms are unable to detect weak motifs while exact methods have been able to detect only short weak motifs. This article proposes an exact tree-based motif detection (TreeMotif) algorithm capable of discovering longer and weaker motifs than by the existing methods.Results: TreeMotif converts the graphical representation of motifs into a tree-structured representation in which a tree that branches with nodes from every sequence represents motif instances. The method of tree construction is novel to motif discovery based on graphical representation. TreeMotif is more efficient and scalable in handling longer and weaker motifs than the existing algorithms in terms of accuracy and execution time. The performances of TreeMotif were demonstrated on synthetic data as well as on real biological data.Availability: https://sites.google.com/site/shqssw/treemotifContact: sunh0013@e.ntu.edu.sgSupplementary information: Supplementary data are available at Bioinformatics online.
