Relationship between insulin, glucose, non-esterified fatty acid and indices of insuliresistance in obese cows during the dry period and early lactation

© 2019, University of Veterinary and Pharmaceutical Sciences. All rights reserved. The aim of this study was to determine to relationship between glucose, insulin, non-esterified fatty acid (NEFA) and indices of insulin resistance in the dry period (DP) and early lactation (EL). The importance of this study was in determining the relation between insulin sensitivity in DP and insulin resistance in EL. A total of 30 normally fed Holstein-Friesian cows with a high body condition score (> 3.75) were included in the study. Blood samples were collected in DP (weeks 5–7 ante partum) and EL (weeks 1–2 post partum). Cows in EL showed higher insulin resistance in comparison to DP due to a lower concentration of glucose and insulin, higher concentration of NEFA, lower value of revised quantitative insulin sensitivity check index and higher values of glucose:insulin and NEFA:insulin ratios (lower pancreas responsivnes to glucose and antilipolytic effect of insulin). Higher concentrations of insulin and glucose in the DP lead to a decrease in their concentrations and an increase in glucose:insulin and NEFA:insulin ratios in the EL. The revised quantitative insulin sensitivity check index in DP negatively correlates with the same index in EL, while positively correlating with the NEFA and NEFA:insulin ratio in EL. The EL revised quantitative insulin sensitivity check index value was influenced by dynamic changes (DP minus EL) in the insulin, NEFA, and glucose concentrations. The relationship between the indicators shows that higher insulin sensitivity in the DP increases resistance in EL in normally fed obese dairy cows

Comparison of macromolecular interactions in the cell walls of hardwood, softwood and maize by fluorescence and FTIR spectroscopy, differential polarization laser scanning microscopy and X-ray diffraction

Interactions between macromolecules in the cell walls of different plant origin were compared, namely spruce wood (Picea omorika (PaniA double dagger) PurkiAe) as an example of softwood, maple wood (Acer platanoides L.) as a hardwood and maize stems (Zea mays L.) as a herbaceous plant from the grass family and widely used agricultural plant. Interactions of macromolecules in isolated cell walls from the three species were compared by using Fourier transform infrared spectroscopy, X-ray diffraction and fluorescence spectroscopy. Linear dichroism of the cell walls was observed by using differential polarization laser scanning microscope (DP-LSM), which provides information of macromolecular order. This method has not previously been used for comparison of the cell walls of various plant origins. It was shown that the maize cell walls have higher amount of hydrogen bonds that lead to more regular packing of cellulose molecules, simpler structure of lignin, and a higher crystallinity of the cell wall in relation to the walls of woody plants. DP-LSM and fluorescence spectroscopy results indicate that maize has simpler and more ordered structure than both woody species. The results of this work provide new data for comparison of the cell wall properties that may be important for selection of appropriate plant for possible applications as a source of biomass. This may be a contribution to the development of efficient deconstruction and separation technologies that enable release of sugar and aromatic compounds from the cell wall macromolecular structure

White Book on Physical and Rehabilitation Medicine (PRM) in Europe. Chapter 3. A primary medical specialty: the fundamentals of PRM

In the context of the White Book of Physical and Rehabilitation Medicine (PRM) in Europe, this paper deals with the core concepts at the base of the PRM specialty. These are the essential constituents that make PRM a primary medical specialty, different from all the other medical specialties, and PRM physician the primary medical specialist among the rehabilitation professionals. The core concepts that will be discussed in this Section include: - PRM is a person/functioning oriented specialty, and this makes the specialty different from the organ/disease oriented, or treatment/age specific medical specialties. - PRM physicians have medical responsibilities, like all the other medical specialists, but with an additional specificity of making a functional assessment. - Like the other specialists, PRM physicians provide direct treatments, but they also work leading the multi-professional rehabilitation team, that works in a collaborative way with other professionals and medical specialists. - Due to its function oriented approach, PRM has a multimodal approach including a wide variety of treatment tools (frequently provided by other rehabilitation professionals) and manages all persons' morbidities (health conditions), since it focuses on decreasing impairments and activity limitations to allow the best possible participation of patients. - As PRM bases its work on functioning, it has a transversal role to other specialties: it overlaps with several of them, sharing part of their knowledge, but it is also totally independent from all of them, since it is based on a different and transversal body of knowledge. - PRM is focused on the person and neither on the disease nor on the setting; in fact, PRM is not only transversal to specialties, but also to the settings of care, and PRM physicians should know these different realities: persons with disabilities and those with long-term health conditions in fact move inside the national health systems between various facilities to obtain the best possible functioning and participation through an appropriate rehabilitation process

White Book on Physical and Rehabilitation Medicine (PRM) in Europe. Chapter 4. History of the specialty: where PRM comes from

In the context of the White Book of Physical and Rehabilitation Medicine (PRM) in Europe, this paper deals with the history of the PRM medical specialty. The specialty evolved in different European countries, and sometimes also into the single countries, from different medical streams that finally joined. These included among others: balneology, gymnastic, use of physical agents (water, heat, cold, massage, joint manipulations, physical exercise, etc.). Another important role has been played by the increasing number of people experiencing or likely to experience disability due to improvement of medicine and consequent survivals from wars, accidents and/or big infective epidemics (like polio); these evolutions happened in strict relationship with other specialties like cardiology, neurology, orthopaedics, pneumology, rheumatology, traumatology, creating a knowledge transversal to all of them. Consequently, the PRM specialty has been gradually introduced in the different European countries, however with no uniformity. Subsequently, European Organizations were created for its diffusion and coordination at the level of medical competences and patient care as well as medical teaching and research: The European Federation of Physical Medicine and Rehabilitation - later European Society (ESPRM), The Académie Médicale Européenne de Médecine de Réadaptation (EARME), The PRM Section of the European Union of Medical Specialists and the European College of PRM (served by the UEMS-PRM Board), were created and work today regarding these general aims. Nowadays a uniform definition of the specialty exists in Europe, which is concordant with the internationally accepted description of PRM (based on the ICF-model). Moreover, research in PRM has been mainly improved during recent decades in Europe due to some external as well as internal scientific influences, thus increasing its scientific importance, together with a parallel increase in rehabilitation journals, many of them indexed and some with impact factor (Cr, EJPRM, JRM, among others), as well as a parallel increase in scientific congresses and courses. Last but not least, the recent creation of the Cochrane Rehabilitation field will also give a great boost to this primary medical specialty, as well as the discovery on new physical agents and technologies that diminish activity limitation and participation restriction of disable persons

White Book on Physical and Rehabilitation Medicine (PRM) in Europe. Chapter 8. The PRM specialty in the healthcare system and society

In the context of the White Book of Physical and Rehabilitation Medicine (PRM) in Europe, this paper deals with a global overview of the role of PRM in healthcare systems in Europe. Several documents and reports by WHO and the UN call for the worldwide strengthening of rehabilitation as a key health strategy of the 21st century. Therefore, further implementation of PRM in healthcare systems is crucial. Many aspects need to be considered when implementing PRM in a health system. Since PRM should be provided along the whole continuum of care, a specific phase model has been developed. Those phases depend on patients' functional needs as well as on temporal aspects of a health condition: it can be congenital or acquired, and the disorder can have an acute onset or a progressive or degenerative course. The following phases are described in the paper: habilitation, prehabilitation, PRM in acute settings, in post-acute and in long-term settings. Regular triage and reassessment to assign the patient to the appropriate level and setting of rehabilitation care is mandatory. Therefore, rehabilitation services should be stratified and organized in networks, in order to allow for the best possible care adapted to the individual's needs and goals, over the continuum of care. Providing correct PRM services requires good planning of service delivery, capacity building and resource allocation. The needed resources are human (with complex multi-professional teams), technical (diagnostic and therapeutic equipment, equipment for performing complementary diagnostic means, rehabilitation technology and assistive devices), and financial. Decisions on the allocation of the usually limited resources require a reasoned process and clear and fair criteria. Principles of clinical governance must be respected, and appropriate competencies are required. Disease prevention (primary, secondary and tertiary), health maintenance and support in chronic conditions as well as global health promotion are gaining growing importance in PRM. They include encouraging physical activity and promoting healthy behavior aiming at the maintenance of maximum function and avoiding complications in disabling or progressive conditions. This is discussed in the paper together with some ethical reflections on the choices PRM physicians continuously have to make during service delivery
