Introduction. In contemporary society increased access to and dependence on digital technology has produced richer possibilities for outsourcing memory to external systems, an issue that becomes especially tangible in educational settings. The aim of this paper is to make visible how the changing relations between searching for and memorizing information is formed in the context of elementary scho

The objective of this study was to assess erysipelas incidence before and after liposuction treatment for patients suffering from post-mastectomy lymphedema. A prospective cohort study of 130 patients at Skåne University Hospital in Malmö, Sweden with postmastectomy arm lymphedema, who had poor outcomes from prior conservative treatment and clinical signs of subcutaneous adipose tissue hypertrophy

In this study, we assess how the Scania Green Score (SGS5), and the five distinct perceived neighbourhood green dimensions within this area-aggregated index (1 km2 squares), is associated with self-reported physical activity and general health, and if perceived safety and social coherence has a moderating effect. Two independent surveys, both conducted in Scania, Sweden, was used for data on SGS5

We investigated the effects of β-amyloid (Aβ) peptides on cholinergic synaptosomes isolated from the electric organ of the Japanese marine ray Narke japonica. Fresh and pre-incubated solutions of Aβ(1-42) inhibited acetylcholine (ACh) release from the synaptosomes evoked by high [K+] depolarization when incubated with synaptosomes for 10 min before the depolarizing stimulus. A freshly prepared sol

Extracellular signal-regulated kinase 2 (ERK2) is located in the cytoplasm of resting cells and translocates into the nucleus upon extracellular stimuli by active transport of a dimer. Passive transport of an ERK2 monomer through the nuclear pore is also reported to coexist. We attempted to characterize the cytoplasmic retention and nuclear translocation of fusion proteins between deletion and sit

Embryonic ventral mesencephalic tissue from the pig is a potential alternative donor tissue for neural transplantation to Parkinson's disease patients. For stable graft survival, the host immune response has to be prevented. This study was performed in order to analyze the mechanisms and dynamics of neural xenograft rejection, as well as neurobiological properties of the donor tissue. Adult normal

BACKGROUND: Embryonic xenogeneic neural tissue is an alternative for transplantation in Parkinson's disease, but immune responses limit the application. The aims of this study were to enhance the in vitro viability rates by donor tissue pretreatment; to compare the efficacy of cyclosporine A (CsA) and tacrolimus (FK) in inhibiting xenograft rejection in rats; to evaluate additional inductive thera

Transplantation of embryonic porcine neurons may restore neurological function in patients with Parkinson's disease, if immunological rejection could be prevented. This study was performed to investigate the role of natural killer cells (NK cells) and NK1.1+ T cells (NK T cells) in the rejection of neural xenografts. A cell suspension was prepared from the ventral mesencephalon of 26-27-day-old pi

Neural transplantation may become an important treatment alternative for focal brain disorders. To date, the most successful grafts have been obtained in patients with Parkinson's disease. Completely normalized dopamine production and reduction of Parkinsonian symptoms have been demonstrated 10 years after grafting. However, the allogeneic donor tissue has to be obtained from induced abortions, an

Neural transplantation holds promise for focal CNS repair. Owing to the shortage of human donor material, which is derived from aborted embryos, and ethical concerns over its use, animal donor tissue is now considered an appropriate alternative. In the USA, individuals suffering from Parkinson's disease, Huntington's disease, focal epilepsy or stroke have already received neural grafts from pig em

Transplantation of neural tissue is an effective therapeutical approach in Parkinson's disease, but the method is constrained by the lack of suitable donor material. Embryonic neural tissue from pigs, xenografts, is considered as an alternative source of donor tissue. The attitudes towards neural tissue grafting in general and xenografts in particular were investigated by interviewing a group of p

Transplantation of neural tissue from other species has the potential to improve function in patients with neurodegenerative disorders. We investigated the functional effects of embryonic porcine dopaminergic neurons transplanted in a rat model of Parkinson's disease and the immune responses to the grafts in immunosuppressed and nonimmunosuppressed hosts. Twenty-three rats with unilateral 6-hydrox

Embryonic allografted human tissue in patients with Parkinson's disease has been shown to survive and ameliorate many of the symptoms of this disease. Despite this success, the practical problems of using this tissue coupled to the ethical restrictions of using aborted human fetal tissue have lead to an exploration for alternative sources of suitable material for grafting, including xenogeneic emb

Intracerebral transplantation of porcine embryonic dopamine-producing neurons has been suggested as a method to treat patients with Parkinson's disease. Even though the brain is an immunologically privileged site, neuronal xenografts are usually rejected within a few weeks. T cells are important for this process, but the exact cellular events leading to rejection are poorly characterized. Brain ce

BACKGROUND: The immune response against discordant xenografts in the brain is incompletely understood and remains a major obstacle for future clinical applications of xenogeneic neural tissue transplants in neurodegenerative disorders. To determine the role of antibodies in the rejection process, we compared graft survival and immune reactions between immunoglobulin deficient (IgKO) and normal mic

The causes of death of transplanted neurons are not known in detail, but apoptotic mechanisms involving caspase activation are likely to play a role. We examined whether overexpression of the anti-apoptotic protein Bcl-2 may enhance the survival of dopaminergic [tyrosine hydroxylase (TH)-immunoreactive] grafted neurons. For this purpose, we prepared cells from embryonic day 13 ventral mesencephalo

Transplantation of porcine embryonic brain cells, including dopaminergic neurons, from ventral mesencephalon (VM) is considered a potential treatment for patients with Parkinson's disease. In the present study, we characterized the distribution among VM cells of the major porcine endothelial xenoantigen, the Galalpha1,3Gal epitope, and evaluated the cytotoxic effect of anti-Galalpha1,3Gal antibody
