R package hiphop: parentage assignment using bi-allelic genetic markers. Statistical software

Can be used for paternity and maternity assignment and outperforms conventional methods where closely related individuals occur in the pool of possible parents. The method compares the genotypes of offspring with any combination of potentials parents and scores the number of mismatches of these individuals at bi-allelic genetic markers (e.g. Single Nucleotide Polymorphisms). It elaborates on a prior exclusion method based on the Homozygous Opposite Test (HOT; Huisman 2017 ) by introducing the additional exclusion criterion HIPHOP (Homozygous Identical Parents, Heterozygous Offspring are Precluded; Cockburn et al., in revision). Potential parents are excluded if they have more mismatches than can be expected due to genotyping error and mutation, and thereby one can identify the true genetic parents and detect situations where one (or both) of the true parents is not sampled. Package 'hiphop' can deal with (a) the case where there is contextual information about parentage of the mother (i.e. a female has been seen to be involved in reproductive tasks such as nest building), but paternity is unknown (e.g. due to promiscuity), (b) where both parents need to be assigned, because there is no contextual information on which female laid eggs and which male fertilized them (e.g. polygynandrous mating system where multiple females and males deposit young in a common nest, or organisms with external fertilisation that breed in aggregations)

How does the general public balance convenience and cognitive pharmaceutical services in community pharmacy practice

Background: Community pharmacy is shifting its focus from traditional, product-focused roles to the provision of cognitive pharmaceutical services (CPS). Previous research has indicated that community pharmacists predominantly want to devote their capacity to CPS. Ideally, services provided also address users' needs. The general public's preferences regarding the services provided by community pharmacists are currently less understood. Aim: This study investigates the general public's preferences and perceived importance of CPS versus convenience in community pharmacy practice. Method: An online survey of 1.500 members of the Dutch Health Care Consumer Panel containing questions regarding preferences for CPS and convenience was distributed. Descriptive statistics and linear regression analysis were performed to investigate the relationship between preferences and participant characteristics. Results: 516 panel members completed all questions regarding preferences and importance of the availability of services. The majority preferred convenience (68.2%) and a smaller proportion preferred CPS (27.7%). However, participants considered it important from a societal viewpoint that CPS is provided (45.0%). Participants who preferred CPS over convenience were generally older (p < 0.001) and used more medicines (p < 0.001). Conclusion: Convenience of community pharmacy services is most preferred by the general public. However, CPS is perceived as important, especially for elderly who use more medicines. Elderly patients who use more medicines more often rate CPS as more important than convenience. These findings suggest that community pharmacists should ensure that pharmacy logistics are organized efficiently before focusing on the provision of CPS

Effect of depolarizing concentrations of potassium on calcium uptake and metabolism in rat liver

AbstractExposure of perfused livers of fed rats to 60 mM K+ induces rapid responses in the Ca2+-sensitive metabolic events, glycogenolysis, cytoplasmic and mitochondrial NADH/NAD ratios and octanoate oxidation. All increase within 45 s of K+ addition. Metabolic responses were not observed following K+ addition to livers perfused in the absence of added Ca2+. Movements of Ca2+ into the liver were suggested from experiments in which 45Ca2+ uptake was measured. The Ca2+ antagonists verapamil, diltiazem and Ni2+ essentially abolished changes to tissue metabolism and Ca2+ fluxes induced by K+ addition. K+-induced changes were consistent with Ca2+ channel activiation.LiverPotassium depolarizationGlycogenolysisCalcium antagonis

Effect of improving diet quality by feeding supplements on methane emission in different production systems of beef cattle in Brazil.

In Brazil, the national inventories on methane emission are carried out using the Tier 2 approach published by the Intergovernmental Panel on Climate Change (IPCC). Although, IPCC recommends the use of a more specific Tier 3 approach, this is hampered by a lack of consolidated data for development, evaluation and application of such a Tier 3 approach

Winter mortality of a passerine bird increases following hotter summers and during winters with higher maximum temperatures

Climate change may influence animal population dynamics through reproduction and mortality. However, attributing changes in mortality to specific climate variables is challenging because the exact time of death is usually unknown in the wild. Here, we investigated climate effects on adult mortality in Australian superb fairy-wrens (Malurus cyaneus). Over a 27-year period, mortality outside the breeding season nearly doubled. This nonbreeding season mortality increased with lower minimum (night-time) and higher maximum (day-time) winter temperatures and with higher summer heat wave intensity. Fine-scale analysis showed that higher mortality in a given week was associated with higher maxima 2 weeks prior and lower minima in the current fortnight, indicating costs of temperature drops. Increases in summer heat waves and in winter maximum temperatures collectively explained 62.6% of the increase in mortality over the study period. Our results suggest that warming climate in both summer and winter can adversely affect survival, with potentially substantial population consequences

Fc receptor-mediated immunity against Bordetella pertussis

The relevance of specific Abs for the induction of cellular effector functions against Bordetella pertussis was studied. IgG-opsonized B. pertussis was efficiently phagocytosed by human polymorphonuclear leukocytes (PMN). This process was mediated by the PMN IgG receptors, FcγRIIa (CD32) and FcγRIIIb (CD16), working synergistically. Furthermore, these FcγR triggered efficient PMN respiratory burst activity and mediated transfer of B. pertussis to lysosomal compartments, ultimately resulting in reduced bacterial viability. Bacteria opsonized with IgA triggered similar PMN activation via FcαR (CD89). Simultaneous engagement of FcαRI and FcγR by B. pertussis resulted in increased phagocytosis rates, compared with responses induced by either isotype alone. These data provide new insights into host immune mechanisms against B. pertussis and document a crucial role for Ig-FcR interactions in immunity to this human pathogen.Centro de Investigación y Desarrollo en Fermentaciones Industriale
