Evidence that lysis of the modified erythrocytes was complement-mediated was provided by the chelation and subsequent restoration of calcium in the plasma. Thus, such modified human erythrocytes could be used as an alternative to animal-derived erythrocytes in haemolysis assays, in order to evaluate complement activity in human plasma during, for example, the screening of patients for complement deficiencies and other abnormalities in a clinical setting.The fate of experimental animals represents an ethical dilemma and a public concern. In the EU, Directive 2010/63/EU allows the rehoming of former experimental animals instead of euthanasia. However, to our knowledge, there are no previous reports of rehoming Beagles in Finland. This study aimed to describe the process behind the first rehoming of laboratory Beagles at the University of Helsinki and evaluate its success. In total, 16 former laboratory Beagles were rehomed in collaboration with animal protection organisations and the University of Helsinki. The dogs had participated in animal cognition studies and had undergone minor procedures during the development of a veterinary drug. While the dogs were still in the laboratory, a socialisation training programme lasting several months was undertaken. Through surveying of the adoptive owners, and interviewing the various stakeholders involved (researchers, animal protection organisations and animal caretakers), the overall process was evaluated, including the socialisation training programme; the comparative success of rehoming younger compared to older animals; the criteria that were used for the selection of the adoptive owners; and the eventual success of rehoming the dogs with the new owners. The majority of the dogs adjusted well to their new home environment. Euthanasia at the end of their experimental use would have been unnecessary and possibly against the objectives of European directives.High-fat diet (HFD) leads to systemic low-grade inflammation, which has been involved in the pathogenesis of diverse metabolic and inflammatory diseases. Colon is thought to be the first organ suffering from inflammation under HFD conditions due to the pro-inflammatory macrophages infiltration, however, the mechanisms concerning the induction of pro-inflammatory phenotype of colonic macrophages remains unclear. Molidustat clinical trial In this study, we show that HFD increased the percentage of gram-positive bacteria, especially genus Clostridium, and resulted in the significant increment of fecal deoxycholic acid (DCA), a gut microbial metabolite produced by bacteria mainly restricted to genus Clostridium. Notably, reducing gram-positive bacteria with vancomycin diminished fecal DCA and profoundly alleviated pro-inflammatory macrophage infiltration in colon, whereas DCA-supplemented feedings to vancomycin-treated mice provoked obvious pro-inflammatory macrophage infiltration and colonic inflammation. Meanwhile, intra-peritoneal administration of DCA also elicited considerable recruitment of macrophages with pro-inflammatory phenotype. Mechanistically, DCA dose-dependently promoted M1 macrophage polarization and pro-inflammatory cytokines production at least partially through toll-like receptor 2 (TLR2) transactivated by M2 muscarinic acetylcholine receptor (M2-mAchR)/Src pathway. In addition, M2-mAchR mediated increase of TLR2 transcription was mainly achieved via targeting AP-1 transcription factor. Moreover, NF-κB/ERK/JNK signalings downstream of TLR2 are involved in the DCA-induced macrophage polarization. In conclusion, our findings revealed that high level DCA induced by HFD may serve as an initiator to activate macrophages and drive colonic inflammation, thus offer a mechanistic basis that modulation of gut microbiota or intervening specific bile acid receptor signaling could be potential therapeutic approaches for HFD-related inflammatory diseases.

To compare systemic exposure to levonorgestrel (LNG) released from commercially available intrauterine systems (IUSs), a subdermal implant, and oral contraceptives.

An integrated population pharmacokinetic (popPK) analysis of data from over 3400 individuals in ten clinical studies with six different LNG-releasing contraceptives (four long-acting reversible contraceptives [LARCs LNG-IUS 8, 12, and 20, initially releasing LNG 14, 17.5, and 20 μg/day, a subdermal implant initially releasing LNG 100 μg/day according to label]; progestin-only pill [POP LNG 30 μg/day]; and combined oral contraceptive [COC] pill [LNG 100 μg/day and ethinylestradiol 20 μg/day]), was conducted to generate a popPK model. LNG release rates, and total and unbound serum/plasma LNG concentrations with LARCs were estimated over the indicated period of use; maximum (C

) and average (C

) serum LNG concentrations were estimated at steady state for oral contraceptives. Influence of body weight on LNG PK was also investigated.

Serum LNG concentration with LARCs increased with increasing daily LNG release rate, being lowest with LNG-IUS 8, higher with LNG-IUS 12 and LNG-IUS 20, and highest with the subdermal implant (1.7-2.1-times that with LNG-IUS 20). Compared with early serum LNG concentrations with LNG-IUS 20, C

and C

were 1.7- and 4.5-fold higher with POP, and 8.6- and 18-fold higher with COC. Total LNG bioavailability was >97% for the LNG-IUSs and 66-80% with other contraceptives. Serum/plasma LNG concentrations decreased with increasing body weight.

Among the contraceptives examined, COC had the highest and LNG-IUSs the lowest systemic exposure to LNG. Systemic LNG concentration was inversely correlated to body weight.

Among the contraceptives examined, COC had the highest and LNG-IUSs the lowest systemic exposure to LNG. Systemic LNG concentration was inversely correlated to body weight.Intimate partner violence (IPV)-defined as physical, psychological, sexual, and/or economic violence typically experienced by women at home and perpetrated by their partners or expartners-is a pervasive form of violence that destroys women's feelings of love, trust, and self-esteem, with important negative consequences on physical and psychological health. Many reports from several countries have underlined a remarkable increase in the cases of IPV during the COVID-19 emergency. In this opinion article, we discussed the hypothesis that such an increase may be related to the restrictive measures enacted to contain the pandemic, including women's forced cohabitation with the abusive partner, as well as the exacerbation of partners' pre-existing psychological disorders during the lockdown. In addition, we retrospectively analyzed some data derived from our practice in a public Italian referral center for sexual and domestic violence (Service for Sexual and Domestic Violence [SVSeD]). These data interestingly revealed an opposite trend, that is, a decrease in the number of women who sought assistance since the beginning of the COVID-19 outbreak.
