High Pressure Compression-Molding of α-Cellulose and Effects of Operating Conditions

Commercial α-cellulose was compression-molded to produce 1A dog-bone specimens under various operating conditions without any additive. The resulting agromaterials exhibited a smooth, plastic-like surface, and constituted a suitable target as replacement for plastic materials. Tensile and three-points bending tests were conducted according to ISO standards related to the evaluation of plastic materials. The specimens had strengths comparable to classical petroleum-based thermoplastics. They also exhibited high moduli, which is characteristic of brittle materials. A higher temperature and higher pressure rate produced specimens with higher mechanical properties while low moisture content produced weaker specimens. Generally, the strong specimen had higher specific gravity and lower moisture content. However, some parameters did not follow the general trend e.g., thinner specimen showed much higher Young’s Modulus, although their specific gravity and moisture content remained similar to control, revealing a marked skin-effect which was confirmed by SEM observations.     

Natural infection in Pampas fox (Lycalopex gymnocercus) by Lagochilascaris major Leiper, 1910 (Nematoda: Ascarididae) in Buenos Aires,Argentina

Parasitology Research - Lagochilascariosis is an emerging parasitic disease limited to the American continent, caused by nematodes of the genus Lagochilascaris. Its life cycle is heteroxenous,...     

CXCL1 can be regulated by IL-6 and promotes granulocyte adhesion to brain capillaries during bacterial toxin exposure and encephalomyelitis

Background  

Granulocytes generally exert protective roles in the central nervous system (CNS), but recent studies suggest that they can be detrimental in experimental autoimmune encephalomyelitis (EAE), the most common model of multiple sclerosis. While the cytokines and adhesion molecules involved in granulocyte adhesion to the brain vasculature have started to be elucidated, the required chemokines remain undetermined.     

Behavioural phenotype of a patient with a de novo 1.2 Mb chromosome 4q25 microdeletion

A female patient, 20 years of age, is reported with a history characterized by developmental and psychomotor delay, and during grammar-school period increasing learning problems, ritualistic behaviours and social withdrawal. Subsequently, challenging and autistic-like behaviours became prominent. The patient showed mild facial dysmorphisms, long thin fingers with bilateral mild short V metacarpals, and hyperlaxity of the joints. Neuropsychiatric examination disclosed obsessive, ritualistic behaviours and vague ideas of reference. Neuropsychological assessment demonstrated mild intellectual disability, mental inflexibility and incongruent affect. MRI-scanning of the brain showed no relevant abnormalities. Genome wide SNP array analysis revealed a 1.2 Mb de novo interstitial microdeletion in 4q25 comprising 11 genes, that was considered to be causative for the developmental delay, perseverative cognitive phenotype and dysmorphisms.To the authors knowledge, this is the first report of a de novo 4q25 microdeletion that presents with a specific behavioural phenotype.     

Measuring social participation: reliability of the LIFE-H in older adults with disabilities

Purpose: Much more attention should be paid to instruments documenting social participation as this area is increasingly considered a pivotal outcome of a successful rehabilitation. The purpose of this study was to document the reliability of a participation measure, the Assessment of Life Habits (LIFE-H), in older adults with functional limitations.

Methods: Eighty-four individuals with physical disabilities living in three different environments were assessed twice with the LIFE-H, an instrument that documents the quality of social participation by assessing a person's performance in daily activities and social roles (life habits).

Results: The intraclass correlation coefficients (ICC) computed for intrarater reliability exceeded 0.75 for seven out of the 10 life habits categories. For interrater reliability, the total score and daily activities subscore are highly reliable (ICC ??0.89), and the social roles subscore is moderately reliable (ICC?=?0.64). ‘Personal care’ is the category with the highest ICC, and for five other categories ICCs are moderate to high (<?0.60).

Conclusion: LIFE-H is a valuable addition to instruments that mostly emphasize the concepts of function or functional independence. It is particularly meaningful to evaluate the participation of older adults in significant social role domains such as recreation and community life. It may be considered among the instruments having the best fit with the ICF definition of participation (the person's involvement in a life situation) and a majority of its related domains.     

Comparison of user groups' perspectives of barriers and facilitators to implementing electronic health records: a systematic review

Background  

Electronic health record (EHR) implementation is currently underway in Canada, as in many other countries. These ambitious projects involve many stakeholders with unique perceptions of the implementation process. EHR users have an important role to play as they must integrate the EHR system into their work environments and use it in their everyday activities. Users hold valuable, first-hand knowledge of what can limit or contribute to the success of EHR implementation projects. A comprehensive synthesis of EHR users' perceptions is key to successful future implementation. This systematic literature review was aimed to synthesize current knowledge of the barriers and facilitators influencing shared EHR implementation among its various users.
