Clinical pharmacokinetics of atenolol — A review

1982

Atenolol is a hydrophilic betareceptor blocking drug, which is predominantly eliminated via the kidneys, only about 5% of the atenolol is metabolised by the liver. After oral administration atenolol is incompletely absorbed from the intestine, so about 50% of the beta blocker are finally biovailable. In plasma only 3% of atenolol are protein-bound. There exists a linear relationship between the atenolol plasma levels and the degree of beta blocking effect measured by inhibition of the exercise-induced tachycardia. No correlation was found between plasma levels of atenolol and blood pressure lowering activity of the drug. After oral administration elimination half life of atenolol is calcula…

Transcription factors controlling development and function of innate lymphoid cells.

2014

Abstract Innate lymphoid cells (ILCs) are a heterogeneous group of lymphocytes, which play an important role in tissue homeostasis at epithelial surfaces. They are scarce in spleen and lymph nodes, but substantial numbers can be found in the intestinal mucosa even at steady state. There, they represent the first line of defence against invading pathogens and contribute to lymphorganogenesis, tissue repair and, when inappropriately activated, immune pathology. Lineage-specific development, function and maintenance of these cells depend on a restricted set of transcription factors that partially emerged as a result of diversification and selection during vertebrate evolution. The differential…

Immune Modulating Effects of NKT Cells in a Physiologically Low Dose Leishmania major Infection Model after αGalCer Analog PBS57 Stimulation

2014

Leishmaniasis is a parasitic infection affecting ∼12 million people worldwide, mostly in developing countries. Treatment options are limited and no effective vaccines exist to date. Natural Killer T (NKT) cells are a conserved innate-like lymphocyte population with immunomodulating effects in various settings. A number of reports state a role of NKT cells in different models of Leishmania infection. Here, we investigated the effect of NKT cells in a physiologically relevant, intradermal low dose infection model. After inoculation of 103 infectious-stage L. major, comparable numbers of skin-immigrating NKT cells in both susceptible BALB/c mice and resistant C57BL/6 mice were noted. Compared …

Pharmacokinetics of new oral anticoagulants: implications for use in routine care

2018

Introduction: Since 2008, new oral anticoagulants (NOACs) have been approved for the prevention of venous thromboembolism (VTE) in patients receiving hip or knee replacement surgery, prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF), treatment of deep vein thrombosis (DVT), and pulmonary embolism (PE). Premarketing randomized clinical trials (RCTs) of NOACs demonstrated their non-inferiority in terms of efficacy vs. warfarin (traditional oral anticoagulant–TOA), with lower risk of serious adverse drug reactions, especially cerebral hemorrhages. In clinical practice, pharmacokinetic aspects of NOACs have to be carefully taken into account to …

Bacteriophage Adherence to Mucus Mediates Preventive Protection against Pathogenic Bacteria

2019

The mucosal surfaces of animals are habitat for microbes, including viruses. Bacteriophages—viruses that infect bacteria—were shown to be able to bind to mucus. This may result in a symbiotic relationship in which phages find bacterial hosts to infect, protecting the mucus-producing animal from bacterial infections in the process. Here, we studied phage binding on mucus and the effect of mucin on phage-bacterium interactions. The significance of our research is in showing that phage adhesion to mucus results in preventive protection against bacterial infections, which will serve as basis for the development of prophylactic phage therapy approaches. Besides, we also reveal that exposure to m…

Melting point, molecular symmetry and aggregation of tetrachlorobenzene isomers: the role of halogen bonding

2018

Tetrachlorobenzenes represent one of the best known, but not yet fully understood, group of isomers of the structure–melting point relationship. The differences in melting temperatures of these structurally related compounds were rationalized in terms of the hierarchy and nature of formed noncovalent interactions, and the molecular aggregation that is influenced by molecular symmetry. The highest melting point is associated with the highly symmetric 1,2,4,5-tetrachlorobenzene isomer. The structures of less symmetrical 1,2,3,4-tetrachlorobenzene and 1,2,3,5-tetrachlorobenzene, determined at 270 and 90 K, show a distinct pattern of halogen bonds, characterized by the different numbers and typ…

From experiencing sites of past to the future of the Demolition Man and how graffiti fits to all

2019

This paper explores the possibilities graffiti can provide to research user experience, focusing in those that might emerge in urban environments. The concept of User Experience (UX) can be seen as a consciously experienced phenomenon entailing for example biological, psychological and cultural, spatial and temporal aspects. Graffiti can be used as a tool to study experiences and meanings in physical and social places and practices. This can be done by studying direct experiences while completing a task, but also for example by narratives and memories involving graffiti. As the technology develops, it is incorporated in our lives, becoming more adaptive and virtual. This might have a strong…

Pleasant Musical Imagery : Eliciting Cherished Music in the Second Person

2019

This article introduces the notion of pleasant musical imagery (PMI) for denoting everyday phenomena where people want to cherish music ‘‘in their heads.’’ This account differs from current paradigms for studying musical imagery in that it is not based a priori on (in)voluntariness of the experience. An empirical investigation of the structure and experiential content in 50 persons’ experiences of PMI applied the elicitation interview method. Peer judgments of the interviews helped to bridge a phenomenological investigation of particular experiences with systematic between-subjects analysis. Both structural features of the imagery (e.g., Looseness of structure or Looping) and content featur…
