Magnetic behaviour of non-interacting colloidal iron oxide nanoparticles in physiological solutions

Magnetic properties of colloidal nanoparticles (NPs) depend on various parameters, such as size, size distribution, interparticle distance, shape, condition of synthesis and stabilizing surfactants. Nowadays, those magnetic nanoparticles (MNPs) are preferably produced in hydrophobic organic solvents, while biomedical applications need hydrophilic properties. Thus, a major challenge is the hydrophilization of the particles, while avoiding destabilization and aggregation. Here we present magnetic characteristics of non-interacting, highly crystalline iron oxide NPs in physiological solutions that are coated with modified polyacrylic acid. The magnetic analysis comprised both static and dynamic magnetic behaviour of 4 nm NPs. The NPs have been further characterized by transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX)

Attitudes towards breastfeeding among mothers of children treated at the University Children's Hospital in Lublin

Introduction According to the current state of knowledge, breastfeeding is the best method of feeding newborns, infants and young children. World organizations and associations and authorities of the medical world recommend breast milk as the most suitable for the proper development of the child. Natural feeding brings many important health benefits, both for the mother and the child, and promotes the formation of emotional ties. It is also economical and convenient to use. The purpose of the studywas to assess the attitudes of women towards breastfeeding and the state of their knowledge on the subject. Material and methods The study group consisted of 96 mothers of children treated in the Department of Neonate and Infant Pathology at the University Children's Hospital in Lublin. The study used the method of a diagnostic survey using a questionnaire constructed by the authors. The obtained results were analyzed using the STATISTICA 12.5 program. Results 53.9% of respondents gave a positive answer to the question about breastfeeding their own child. As the main reasons for its interruption were given most often too little food (36.6%) and child's illness (26.8%). 79.8% of women replied that the help of health care workers in breastfeeding training is needed, but only 56.2% of respondents believe that the information obtained was sufficient. Only 41.6% of respondents knew that lactation affects fertility and the possibility of becoming pregnant. In the question whether breastfeeding allows a better relationship between the mother and the child, 95.5% gave a positive answer. 98.9% emphasized the positive impact of breastfeeding on the relationship between parents. As many as 60.7% of women intended to give up natural feeding after returning to work. Conclusions A surprisingly high percentage of women resign from natural feeding, despite relatively good knowledge about the benefits resulting from it. Advice from healthcare professionals is an important source of information for women. Breastfeeding after returning to work is an important problem

Effect of surfactant for magnetic properties of iron oxide nanoparticles

For different medical applications nanoparticles (NPs) with well-defined magnetic properties have to be used. Coating ligand can change the magnetic moment on the surface of nanostructures and therefore the magnetic behavior of the system. Here we investigated magnetic NPs in a size of 13 nm conjugated with four different kinds of surfactants. The surface anisotropy and the magnetic moment of the system were changed due to the presence of the surfactant on the surface of iron oxide NPs

How do occupational therapy curricula align with priorities identified by occupational therapists to prepare graduates for working in mental health?

All professional preparation programs need to ensure that university curricula remain reflective of current practice, and also prepare graduates for practice in the future. Upon formation, the Australia and New Zealand Occupational Therapy Mental Health Academics (ANZOTMHA) network identified that there was insufficient or poorly organised information available about how well current occupational therapy curricula prepared students for practice in the field of mental health. One of the first priorities established by ANZOTMHA was to undertake a program of research to examine this issue. The aim of this report is to summarise and integrate the outcomes of two inter-related studies to explore the extent to which current occupational therapy university curricula in Australia and New Zealand match educational priorities identified by practising occupational therapists in mental health

Protection of antique cemeteries. Legal and organizational problems.

"Praca traktuje o problematyce ochrony cmentarzy zabytkowych na terenach Polski. Zawarte są w niej informacje na temat regulacji prawnych, organizacji całych kompleksów i wartościach jakie posiadają zabytkowe nekropolie. Pisze w niej również o drzewostanie, czy problemach rewitalizacji pojedynczych nagrobków jak i całych kompleksów cmentarnych. "The work deals with the issues of protection of historic cemeteries on Polish territory. It contains information on the legal regulations, the organization of entire complexes and values which have historic cemeteries. It also writes about revitalization problems of individual graves and whole complexes of cemetery
