Background: The knowledge about the relationship between health-related activities on the Internet (i.e. informed citizens) and individuals' control over their own experiences of health or illness (i.e. empowered citizens) is valuable but scarce. In this paper, we investigate the correlation between four ways of using the Internet for information on health or illness and citizens attitudes and behaviours toward health professionals and health systems and establish the profile of empowered eHealth citizens in Europe. Methods. Data was collected during April and May 2007 (N = 7022), through computer-assisted telephone interviews (CATI). Respondents from Denmark, Germany, Greece, Latvia, Norway, Poland and Portugal participated in the survey. The profiles were generated using logistic regressions and are based on: a) socio-demographic and health information, b) the level of use of health-related online services, c) the level of use of the Internet to get health information to decide whether to consult a health professional, prepare for a medical appointment and assess its outcome, and d) the impact of online health information on citizens' attitudes and behavior towards health professionals and health systems. Results: Citizens using the Internet to decide whether to consult a health professional or to get a second opinion are likely to be frequent visitors of health sites, active participants of online health forums and recurrent buyers of medicines and other health related products online, while only infrequent epatients, visiting doctors they have never met face-to-face. Participation in online health communities seems to be related with more inquisitive and autonomous patients. Conclusions: The profiles of empowered eHealth citizens in Europe are situational and country dependent. The number of Europeans using the Internet to get health information to help them deal with a consultation is raising and having access to online health information seems to be associated with growing number of inquisitive and self-reliant patients. Doctors are increasingly likely to experience consultations with knowledgeable and empowered patients, who will challenge them in various ways. © 2011 Santana et al; licensee BioMed Central Ltd.

Background: Because terminal sugars of α-1-acid glycoprotein (AGP) are reported to be involved in anti-inflammatory and immunomodulatory processes, their expressions might have an influence on the proper function of immune system of newborns. Here, relative amounts of sialylated and fucosylated glycotopes on human milk AGP over normal lactation were investigated. Materials and Methods: AGP concentration and relative amounts of its sialylated and fucosylated glycovariants were analyzed in early colostrum, colostrum, and transitional and mature milk samples of 127 healthy mothers by lectin-AGP enzyme-linked immunosorbent assay using α2,3-and α2,6-sialic acid and α1,2-, α1,3-, and α1,6-fucose specific biotinylated Maackia amurensis, Sambucus nigra, Ulex europaeus, Tetragonolobus purpureus, and Lens culinaris lectins, respectively. Results: AGP concentration in human milk was about 30 times lower than in plasma of lactating mothers and decreased gradually over lactation. Milk AGP showed significantly higher expression of sialylated and fucosylated glycotopes in comparison with those of plasma AGP. Milk AGP glycovariants containing α2,6-sialylated and α1,6-and α1,2-fucosylated glycotopes showed the highest relative amounts in early colostrums. With progression of lactation, the expressions of glycotopes α1,2-fucosylated decreased starting from Day 4 and those of α2,6-sialylated and α1,6-fucosylated from Day 8 of lactation, whereas the level of α2,3-sialyl-glycotope was almost constant over 45 days of lactation. In contrast, the expression of α1,3-linked fucose on AGP was low in colostrums and significantly higher in transitional and mature milk. Conclusions: The relative amounts of sialylated and fucosylated glycovariants of human hindmilk AGP significantly varied between Days 2 and 45 of normal lactation. © Copyright 2014, Mary Ann Liebert, Inc. 2014.

Visible-range circular dichroism titrations were used to study Cu(II) binding properties of Multimetal Binding Site (MBS) of Human Serum Albumin (HSA). The formation of ternary MBS-Cu(II)-Buffer complexes at pH 7.4 was positively verified for sodium phosphate, Tris, and Hepes, the three most common biochemical buffers. The phosphate > Hepes > Tris order of affinities, together with strong spectral changes induced specifically by Tris, indicates the presence of both Buffer-Cu(II) and Buffer-HSA interactions. All complexes are strong enough to yield a nearly 100 ternary complex formation in 0.5mM HSA dissolved in 100mM solutions of respective buffers. The effects of warfarin and ibuprofen, specific ligands of hydrophobic pockets I and II in HSA on the Cu(II) binding to MBS were also investigated. The effects of ibuprofen were negligible, but warfarin diminished the MBS affinity for Cu(II) by a factor of 20, as a result of indirect conformational effects. These results indicate that metal binding properties of MBS can be modulated directly and indirectly by small molecules. Copyright © 2010 Magdalena Sokołowska et al. Source

Objective: Vipera berus is the only naturally occurring venomous snake in Poland. Its venom is primarily vasculotoxic and evokes both local and systemic findings. The aim of the study was to review a series of clinical cases of V berus bites occurring in southwest Poland. Methods: The charts of 26 patients (age range, 1666 years; mean, 42 years) hospitalized with V berus bites were retrospectively analyzed using a data collection tool. Demographic and clinical data were extracted. Results: The most common local findings of envenomation were edema of the bitten limb with associated extravasations observed in 24 (92.3%) patients, but in only 1 (3.8%) case did the edema spread to the trunk. In 22 (84.6%) cases edema disappeared within 2 weeks after the bite. Systemic disturbances observed in the patients were: shock (1 case), mild transient hypotension (1 case), prolonged hypotension (3 cases), bronchospasm and laryngeal edema (1 case), diarrhea (1 case), transient supraventricular arrhythmias (2 cases), neutrophilic hyperleukocytosis (2 cases), and thrombocytopenia below 50 000 cells/μL (5 cases). In 16 patients (61.5%) the envenomation was classified as moderate and this type was predominant. Six cases were classified as severe. No fatal case was reported. Treatment included the administration of specific antivenom in 14 cases (in all severe and half of moderate cases) and symptomatic treatment applied in all cases. Conclusions: Moderate envenomation prevailed among the patients analyzed in the study. Antivenom treatment is primarily necessary in cases of severe (grade 3) and in some cases of moderate (grade 2) envenomation, especially in patients with persistent or recurring hypotension. © 2010 Wilderness Medical Society.

SDS-agarose FN immunoblotting of 257 normal and pathological human plasma samples revealed the ladder pattern of multiple plasma FN bands which corresponded to FN monomer and dimer, and 5 FN-fibrin bands with increasing molecular masses. The FN-fibrin bands of about 750 kDa, 1000 kDa, 1300 kDa, 1600 kDa, and 1900 kDa appeared more frequently and in significantly higher relative amounts in the pathological samples (P < 0.000) than in relatively healthy individuals. The revealing of high-molecular FN-fibrin complexes by SDS-agarose FN immunobloting might have the potential to become a laboratory biomarker of some diseases in which the coagulation system is triggered. © 2014 Taylor and Francis Group, LLC.
