Background And Aims: Polyploidy has played an important role in the evolution of ferns. However, the dearth of data on cytotype diversity, cytotype distribution patterns and ecology in ferns is striking in comparison with angiosperms and prevents an assessment of whether cytotype coexistence and its mechanisms show similar patterns in both plant groups. Here, an attempt to fill this gap was made using the ploidy-variable and widely distributed Cystopteris fragilis complex. Read More

Background And Aims: Alpine cushion plants can initially facilitate other species during ecological succession, but later on can be negatively affected by their development, especially when beneficiaries possess traits allowing them to overrun their host. This can be reinforced by accelerated warming favouring competitively strong species over cold-adapted cushion specialists. However, little empirical research has addressed the trait-based mechanisms of these interactions. Read More

Antibodies that bind residue K169 in the V2 region of the HIV-1 envelope correlated with reduced risk of infection in the RV144 vaccine trial but were restricted to two ED-motif-encoding light chain genes. Here, we identify an HIV-infected donor with high-titer V2 peptide-binding antibodies and isolate two antibody lineages (CAP228-16H/19F and CAP228-3D) that mediate potent antibody-dependent cell-mediated cytotoxicity (ADCC). Both lineages use the IGHV5-51 heavy chain germline gene, similar to the RV144 antibody CH58, but one lineage (CAP228-16H/19F) uses a light chain without the ED motif. Read More

RWP-RKs represent a small family of transcription factors (TFs) that are unique to plants and function particularly under conditions of nitrogen starvation. These RWP-RKs have been classified in two sub-families, NLPs (NIN-like proteins) and RKDs (RWP-RK domain proteins). NLPs regulate tissue-specific expression of genes involved in nitrogen use efficiency (NUE) and RKDs regulate expression of genes involved in gametogenesis/embryogenesis. Read More

Wide spread incidences of vaccine-like strains of lumpy skin disease virus (LSDV) have recently been reported in a Russian region with a neighboring country that actively vaccinate with a live attenuated LSD vaccine. The use of live-attenuated viruses (LAVs) as vaccines during an active outbreak, creates potential ground for coinfection of hosts and emergence of a strain combining genetic fragments of both parental vaccine and field strains. In this study, we analyse the vaccine-like strain LSDV RUSSIA/Saratov/2017 detected in Saratovskaya oblast, a region sharing border with Kazakhstan. Read More

Objective: Concomitant treatment with angiotensin-converting enzyme (ACE) inhibitors and dipeptidyl peptidase-4 (DPP-4) inhibitors is increasingly common. Pharmacological studies have suggested a potential adverse drug interaction between ACE inhibitors and DPP-4 inhibitors resulting in unfavorable hemodynamic changes; very few studies have examined such an interaction between angiotensin II receptor blockers (ARBs) and DPP-4 inhibitors. We investigated blood pressure (BP) and heart rate (HR) during treatment with the DPP-4 inhibitor linagliptin in individuals receiving either ACE inhibitors or ARBs in the MARLINA-T2D trial.

The effects of cholesterol on the process of intrinsic lipidation, whereby an acyl chain is transferred from a lipid as donor to a membrane-associated acceptor molecule, have been explored using melittin as the acceptor. Membranes comprising lipids with saturated acyl chains (1,2-dipalmitoyl sn-glycero-3-phosphocholine, DPPC; 1,2-dimyristoyl sn-glycero-3-phosphocholine, DMPC) yielded no acyl transfer, whereas membranes composed of lipids with unsaturated acyl chains (1,2-dioleoyl sn-glycero-3-phosphocholine, DOPC; 1-palmitoyl-2-oleoyl sn-glycero-3-phosphocholine, POPC) produced detectable lipidation activity. For all lipids, inclusion of cholesterol led to a significant increase in lipidation activity, with the greatest effect observed for 20 mol% cholesterol in POPC. Read More
