TIMING AND PATIENTS' POSITION DURING CUFF BLOOD PRESSURE MEASUREMENT AFFECT MYOCARDIAL WORK PARAMETERS MEASURED BY ECHOCARDIOGRAPHY
<p><span>BACKGROUND. Although cuff blood pressure measurement is a critical parameter to calculate myocardial work (MW) noninvasively, there is no recommendation about when and how to measure it. Accordingly, we sought to evaluate the effects of the timing during the echo study and the patient's position on the scanning bed during the cuff blood pressure measurement on MW parameter calculations.</span></p> <p><span>METHODS. 101 consecutive patients (44 women, 66±14 years) undergoing clinically indicated echocardiography were prospectively enrolled. During the echocardiographic study, we measured the cuff blood pressure four times, using a fully automatic digital blood pressure monitor applied to the right arm and left in the same position throughout the stud: BP1 before the start of the echo study, with the patient lying in the supine position; BP2, after positioning the patients on his/her left side to start the echo study; BP3, at the time of the acquisition of the three apical views (4-, 2-chamber, and the long-axis) used to measured left ventricular global longitudinal strain (GLS); and BP4, at the end of the echo study with the patient again in the supine position.</span></p> <p><span>RESULTS. Systolic blood pressure (SBP) at BP1 was 147±21 mm Hg. Between BP1 and BP2, it dropped by 17±9 mm Hg (p<0.05). SBP at BP3 was significantly lower than BP2 (130±20 mm Hg vs. 122±18 mm Hg, p<0.05), and at BP4 was significantly lower than at BP1 (-9±13 mm Hg, p<0.05). The average GLS was -16±3%. Accordingly, the global work index was 1929±441 mmHg% at BP1, dropped to 1717±421 at BP2, decreased to 1602±351 mm Hg% at BP3, and increased to 1815±386 mmHg% at BP4 (p<0.001).</span></p> <p><span>CONCLUSIONS. The timing during the echocardiography study and the patient's position on the scanning bed are critical determinants of the measured cuff SPB and the resulting values of MW parameters. </span></p>
Data for: Recent changes in thermal niche position and breadth of bird assemblages in Spain in relation to increasing temperatures
<p><span><strong>Aim</strong>:</span> <span>Animal communities around the world are responding to climate change by altering their taxonomic composition, mainly through an increase in the colonisation rate of warm-dwelling species and the local extinction of cold-dwelling ones. We assessed whether the taxonomic composition of bird assemblages in peninsular Spain has changed in accordance with the recent increase in temperature. We also evaluated the role of species' thermal affinities and population dynamics in these changes.</span></p> <p><span><strong>Location</strong>:</span><span> Peninsular Spain.</span></p> <p><span><strong>Taxon</strong>:</span><span> Birds.</span></p> <p><span><strong>Methods</strong>:</span> <span>We compared assemblages reported in the last Spanish breeding bird atlases (1998–2002 vs 2014–2019) in 10x10 km squares. We described species' thermal niches by overlaying global species breeding distributions and world temperature metrics (based on mean, minimum, maximum and range), and then aggregated them to obtain a set of community thermal indices for each assemblage (CTIs, and CTR for ranges). Long-term average temperatures and local current temperatures were related to changes in CTIs using spatial GLMMs, which considered habitat change. We identified the species most responsible for variation in assemblages and regressed species' influence on thermal affinities and population dynamics.</span></p> <p><span><strong>Results</strong>: </span><span>CTIs increased with temperature and warm-dwelling species became more prevalent to the detriment of cold-dwelling ones. However, we found a counteracting effect of temperature and habitat. Cold-dwelling forest species were among the most influential species, mainly through colonisation, while warm-dwelling farmland species contributed through local extinctions (both attenuated local increases in CTI). The mean thermal breadth of assemblages (CTR) decreased with temperatures. </span></p> <p><span><strong>Main conclusions</strong>:</span><span> The taxonomic composition of bird assemblages shifted in line with the main expectations due to global change (</span><span>thermophilisation), mainly due to local colonisation of warm-dwelling species</span><span>, although it did not show the pattern of thermal homogenization suggested elsewhere. Our results add further evidence of the interplay between climate warming and land-use change in the ongoing adjustment of animal communities.</span></p>

Data from: The twenty amino acids are identified by unique numbers assigned to the uracil, cytosine, adenine, and guanine found in the three base positions of the sixty-four messenger RNA genetic codons
<p>A codon's three bases consist of any combination of uracil, cytosine, adenine, or guanine and these encode the twenty amino acids. When the codon's first two bases are given specific values, and those values are multiplied, then the third base of the codon is used during translation only when the product is greater than three. Here we show that those values plus more variables within the ribosomal decoding site results in specific flow values for each of the twenty amino acid groups. These results are demonstrated in a flow chart showing the unidirectional flow which is expected during the translation process. All twenty amino acids can be represented by numbers that describe their relationship to each other and to the decoding site. We anticipate our findings will increase discussion about using a number system to better understand the translation process.</p>

Positive effects of liana cutting on seedlings are reduced during El Niño-induced drought
<p><strong>Abstract</strong></p> <p>Liana cutting is a management practice currently applied to encourage seedling regeneration and tree growth in some logged tropical forests. However, there is limited empirical evidence of its effects on forest demographic rates in Southeast Asia. We used 22 four-hectare plots in the Sabah Biodiversity Experiment (a reduced impact logging site) enrichment line planted with 16 dipterocarp species to assess the effects of complete liana cutting on tree growth and survival. We compared plots where lianas were only cut along planting lines (standard enrichment line planting) with those with one (2014) or two rounds (2011 and 2014) of complete liana cutting. We found increased seedling growth following the first complete liana cut in 2011 relative to the enrichment line planting, consistent with previous studies. The response after three years to the cutting in 2014 depended on whether lianas had been previously cut or not: in twice-cut plots, seedling growth was not significantly different from the standard enrichment planting controls, whereas growth in plots with only one complete cut in 2014 was significantly slower. Seedling survival decreased through time for both once- and twice-cut liana treatments but remained stable in controls. Sapling growth after the 2014 liana cutting showed a similar pattern to seedling growth, while tree growth following the 2014 liana cutting was significantly lower than controls regardless of whether lianas were cut twice (2011 and 2014) or once (2014). Differences in response between the two rounds of liana cutting were likely due to changes in precipitation - 2011 was followed by consistent rainfall while 2014 was followed by two severe droughts within 2 years. Synthesis and applications. Our results generally support the widely-reported positive effects of liana cutting on tree growth and survival. However, reduced growth and survival after the 2015/16 El Niño suggests that drought may temporarily undermine the benefits of liana cutting in logged tropical forests. Managers of similar areas in SE Asia should consider halting liana cutting during El Niño events. In other tropical areas, seedling survival should be monitored to assess to what extent results from SE Asia are transferable.</p> <p><strong>Link to data repository:</strong> <a href="https://doi.org/10.5061/dryad.2sq2d9m" target="_blank" rel="noopener">DOI</a></p>
Social network connections are positively related to temperature in winter flocks of black-capped chickadees
<p>Social species often share with conspecifics the responsibilities of finding food, defending against predators or caring for young. Within a social group, individuals' roles can be influenced by age, sex, and personality. Black-capped chickadees, <em>Poecile atricapillus</em>, are nonmigratory passerine birds that spend their winters living in social flocks. Due to the intense metabolic stress placed on chickadees by low winter temperatures, the role of flocking in resource localization and allocation among flockmates is an important aspect of individual fitness, especially during winter. Understanding changes in flock structure in response to the environment may provide insight into the consequences of social behaviour variability on overwinter survival. Here, we used social network analysis to quantify the effects of ambient temperature on social foraging behaviour in winter flocks of black-capped chickadees over two winters in Massachusetts, USA. Contrary to our expectations, we found that two measures of social connection were higher on warm days than on cold days. We found no evidence that sex or dominance rank influenced birds' behavioural responses to temperature. Furthermore, contrary to previous research, we found male-biased sex ratios in most of our flocks. Our findings that birds had more and stronger social connections on warm days and that an individual's response to temperature was not related to their status in a flock beg further investigation as to the specific costs and benefits of flocking in chickadees and other birds.</p>
