01). There were no significant between-group differences in mortality, graft dysfunction, and ventricular mass. We conclude that ivabradine could effectively and consistently reduce the HR in HTx recipients.
Cognitive impairment (CI) is highly prevalent in breast cancer survivors (BCS), and can be a barrier to health-promoting behaviours. However, the ways in which CI may affect self-regulation or motivation to perform such behaviours have not been explored. We assessed if BCS with CI report greater extrinsic self-regulation compared to those without CI and if this relationship persists after controlling for depression.

We recruited BCS with diabetes and assessed cognition and motivation to perform healthy diabetes management behaviours (e.g., diet and exercise). Participants completed a cognitive battery evaluating attention, working memory, executive functioning (EF), processing speed (PS), language and memory. The Treatment Self-Regulation Questionnaire (TSRQ) assessed intrinsic versus extrinsic motivation. Depression was determined by a score ≥16 on the Center for Epidemiological Studies Depression Scale. Wilcoxon rank-sum test compared associations between CI and TSRQ scores.

Participants were 118 older adults (mean age 65 years). Participants with CI in the following domains had higher extrinsic self-regulation scores compared to those without CI attention (p<0.01), PS (p=0.01), EF (p<0.01), language (p=0.02; p=0.04) and memory (p=0.04; p=0.03). After adjusting for depression, the relationship between CI and higher extrinsic self-regulation scores remained significant.

BCS with CI appear to rely more on external sources of motivation to perform health behaviours, regardless of depression. Future studies and interventions to improve health behaviours should consider screening for CI and involving caregivers for those with CI to improve outcomes.

Isolating a novel bacterial source of fructan from a saltern and analysis of its genome to better understand the possible roles of fructans in hypersaline environments.

Bacteria were isolated from crude salt samples originating from Çamaltı Saltern in Western Turkey and screened for fructanogenic traits in high-salt and sucrose-rich selective medium. Exopolysaccharide accumulated in the presence of sucrose by isolate OK12 was purified and chemically characterized via HPLC, FT-IR and NMR, which revealed that it was a levan-type fructan (β-2,6 linked homopolymer of fructose). The isolate was taxonomically classified as Bacillus licheniformis OK12 through 16S rRNA gene and whole-genome sequencing methods. Strain OK12 harbours one levansucrase and two different levanase genes, which altogether were predicted to significantly contribute to intracellular glucose and fructose pools. The isolate could withstand 15% NaCl, and thus classified as a halotolerant.

Fructanogenic traits in halotolerant B. licheniformis OK12 are significant due to predicted influx of glucose and fructose as a result of levan biosynthesis and levan hydrolysis, respectively.

Fructans from the residents of hypersaline habitats are underexplored compounds and are expected to demonstrate physicochemical properties different from their non-halophilic counterparts. Revealing fructanogenic traits in the genome of a halotolerant bacterium brings up a new perspective in physiological roles of fructans.

Scientists keep searching novel anti-influenza drugs, of which natural products present to be an important source. Myricetin, a natural flavonol compound, which exists in many edible plants, which has a wide range of biological activities, but its anti-influenza A virus activity is ambiguous. This study aims to evaluate the anti-influenza activity of myricetin and elucidate its underlying mechanism. Our results demonstrated that myricetin could significantly inhibit influenza A virus replication, reduce viral polymerase activity via selective inhibition of viral PB2 subunit, and the production of inflammatory cytokines by inhibiting TLR3 signaling pathway. The binding affinity analysis and the result of molecular docking revealed that myricetin interacted with the PB2 cap-binding pocket of influenza A virus. The above results suggested myricetin could exhibit anti-influenza virus activity with low cytotoxicity as well, and myricetin had low toxicity in BALB/c mice in vivo. Results from this study highlighted myricetin could be considered as a promising anti-influenza virus agent with dual inhibition profile. Furthermore, the compound with similar structure would provide a new option for the development of novel inhibitors against influenza A virus.Habitats can select for specialized phenotypic characteristics in animals. However, the consistency of evolutionary responses to particular environmental conditions remains difficult to predict. One trait of great ecological importance is brain form, which is expected to vary between habitats that differ in their cognitive requirements. Here, we compared divergence in brain form and oral jaw size across a common littoral-pelagic ecological axis in two sunfishes at both the intraspecific and interspecific levels. Brain form differed between habitats at every level of comparison; however, divergence was inconsistent, despite consistent differences in oral jaw size. Pumpkinseed and bluegill species differed in cerebellum, optic tectum and olfactory bulb size. These differences are consistent with a historical ecological divergence because they did not manifest between littoral and pelagic ecotypes within either species, suggesting constraints on changes to these regions over short evolutionary time scales. There were also differences in brain form between conspecific ecotypes, but they were inconsistent between species. Littoral pumpkinseed had larger brains than their pelagic counterpart, and littoral bluegill had smaller telencephalons than their pelagic counterpart. Inconsistent brain form divergence between conspecific ecotypes of pumpkinseed and bluegill sharing a common littoral-pelagic habitat axis suggests that contemporary ecological conditions and historic evolutionary context interact to influence evolutionary changes in brain form in fishes.Intra-specific variability is a cornerstone of evolutionary success of species. Acquiring genetic material from distant sources is an important adaptive mechanism in bacteria, but it can also play a role in eukaryotes. In this paper, we investigate the nature and evolution of a chromosomal segment of panicoid (Poaceae, Panicoideae) origin occurring in the nuclear genomes of species of the barley genus Hordeum (Pooideae). The segment, spanning over 440 kb in the Asian Hordeum bogdanii and 219 kb in the South American Hordeum pubiflorum, resides on a pair of nucleolar organizer region (NOR)-bearing chromosomes. Conserved synteny and micro-collinearity of the segment in both species indicate a common origin of the segment, which was acquired before the split of the respective barley lineages 5-1.7 million years ago. A major part of the foreign DNA consists of several approximately 68 kb long repeated blocks containing five stress-related protein-coding genes and transposable elements (TEs). https://www.selleckchem.com/products/caffeic-acid-phenethyl-ester.html Whereas outside these repeats, the locus was invaded by multiple TEs from the host genome, the repeated blocks are rather intact and appear to be preserved. The protein-coding genes remained partly functional, as indicated by conserved reading frames, a low amount of non-synonymous mutations, and expression of mRNA. A screen across Hordeum species targeting the panicoid protein-coding genes revealed the presence of the genes in all species of the section Stenostachys. In summary, our study shows that grass genomes can contain large genomic segments obtained from distantly related species. These segments usually remain undetected, but they may play an important role in the evolution and adaptation of species.Glucocorticoids are among the most prescribed drugs globally due to their potent anti-inflammatory and immunosuppressive properties. Although they have positive effects on the treatment of various disease states; long-term administration is associated with high blood pressure, insulin resistance, and susceptibility to type 2 diabetes. The heart attempts to cope with increased blood pressure and a decrease in glucose utilization by developing pathological cardiac remodeling. However, in this process, cardiac fibrosis formation and deterioration in heart structure and functions occur. Galectin-3, a member of the β-galactoside binding lectins, is consistently associated with inflammation and fibrosis in the pathogenesis of various disease states including insulin resistance and heart failure. Galectin-3 expression is markedly increased in activated macrophages and a subset of activated fibroblasts and vascular cells. Also, failing and remodeling myocardium show increased Gal-3 expression and elevated Gal-3 levels are related to heart failure severity and prognosis. Furthermore, Gal-3-related pathways are recently suggested as therapeutic targets both pharmacologically and genetically to increase insulin sensitivity in vivo. The objective of this review is to provide a summary of our current understanding of the role of glucocorticoid-associated insulin resistance, which is important for some cardiac events, and the potential role of galectin in this pathophysiological process.We previously showed that the tenderization of ordinary muscle during ice storage is affected by the interposition of pink muscle fibers in the ordinary muscle. However, little is known about whether or not the interposition of pink muscle fibers affects the hardness of raw fish meat. To clarify the influence of the interposition of pink muscle fibers in the dorsal ordinary muscle on hardness of meat, the breaking strengths and the fiber types of the dorsal ordinary muscle of eight fish species (a total of 37 specimens) were discriminated. The breaking strengths among fish species were within a range of 6.5-19.1 N/cm2 . Pink muscle fibers were found in the dorsal ordinary muscle of six out of the eight fish species ranging from 0.0 to 56.0% in quantity ratio, and 0.0 to 19.3% in area ratio, respectively. The quantity ratio and area ratio of pink muscle fibers in the dorsal ordinary muscles of all eight fish species samples positively correlated with the breaking strength. Relative to the quantity ratio (p less then  .05), the area ratio (p less then  .02) of pink muscle fibers was more representative of postmortem texture hardness. In conclusion, the high interposition ratio of pink muscle fibers in ordinary muscle could potentially improve the postmortem hardness, the texture, and even the flesh quality of raw fish meat.
