Traditionally, resting heart rate variability (rHRV) is measured for 10 min using the last 5 min for analyses (e.g., criterion period). It is unknown whether the measurement period can be shortened in pregnant women as there are currently no established standards. We aimed to compare shorter time segments (e.g., from the 1st to 10th minutes) of the parasympathetic index natural logarithm transformation of root mean square of successive R-R differences (Ln rMSSD) with the criterion period in pregnant and nonpregnant women. Twelve pregnant (age 30.8 ± 3.4 years; gestational age 20.1 ± 5.0 weeks) and 15 nonpregnant women (age 29.8 ± 4.0 years) were included. rHRV was measured using a portable heart rate monitor for 10 min while sitting. Ln rMSSD difference/agreement between shorter time segments and criterion period was analyzed. selleck chemicals llc The result observed between the 4th-5th minutes was the shortest time segment not different from/highly agreed with the criterion period in pregnant women (difference [95% confidence interval (CI)] -0.10 [-0.22 to 0.02]/bias ± 1.96 × SD -0.06 [-0.38 to 0.25]). In nonpregnant women, the 2nd-3rd-minute segment was the shortest with similar results (difference [95% CI] -0.04 [-0.15 to 0.07]/bias ± 1.96 × SD -0.03 [-0.39 to 0.32]). The Ln rMSSD was found to be stable from the 5th-10th minutes and the 3rd-10th minutes in pregnant and nonpregnant women, respectively. A shortened rHRV assessment can increase its applicability in clinical/exercise-training settings. Novelty Ln rMSSD can be measured for 5 min in pregnant women, with the last 1-min segment analyzed. The last 1-min segment from 3 min can be used for rHRV measurement in nonpregnant women. The shortened rHRV assessment can facilitate its applicability in clinical/exercise-training settings.The polyphenolic distribution on different organs of Argylia radiata, an extremophile plant from the Atacama "Flowering Desert", is presented herein for the first time. For this purpose, the total phenolic content and antioxidant capacity of ethanolic extracts from leaves, tuberous root and flowers of different colors were evaluated. Orange and red flowers showed the highest polyphenolic and flavonoid content. The maximum anthocyanin concentration was found in red flowers and the antioxidant activity (FRAP) of extracts changed according to the organ. The UPLC-MS/MS analysis of the extracts allowed to identify 10 new polyphenols belonging to different families. Rutin was identified as the most abundant polyphenol in all plant organs, followed by quercetin and coumaric acid. Their role in plant response to abiotic and biotic stress, as well as their potential biotechnological application are discussed.During many types of interviews (e.g. in employment, with the police, and in healthcare), we need to recall detailed memories of specific events, which can be difficult for autistic people in response to commonly used questions. This is especially because these tend to be open questions (i.e. very broad). Autistic people have disproportionately high rates of physical and mental health conditions, are more likely to interact with police, and are the most underemployed disability group. However, interviewers are often unsure about how to adapt their communication for autistic people. Our research tested whether different types of prompts enabled autistic people to recall specific memories (memories of a single event within one day). Participants were asked about situations relating to witnessing a crime (e.g. at the bank), physical or mental health scenarios and employment interviews (e.g. a time you've met a deadline). We tested the following Open questions basic questions only (e.g. 'tell me about a time you went to the cinema'), Semantic prompting a general prompt (e.g. 'do you enjoy going to the cinema?') before asking for a specific instance ('tell me about a time you went to the cinema?'), Visual-verbal prompting asking participants to recall when it happened, who was there, the actions that occurred, the setting, and any objects. With visual-verbal prompting, autistic and typically developing participants' memories were more specific and detailed. Semantic prompting was also effective for employment questions. Our study shows that autistic people can recall specific memories when they are appropriately prompted. Visual-verbal prompting may be effective across different situations.OBJECTIVE The aim of this study is to determine the effects of a powered exoskeleton on measures of physical and cognitive performance. BACKGROUND US warfighters carry heavy equipment into battle, and exoskeletons may reduce that burden. While exoskeletons are currently evaluated for their effects on physical performance, their cognitive effects are not currently considered. METHOD Twelve military members participated in a simulated patrol task under three conditions wearing a powered exoskeleton (PWR), an unpowered exoskeleton (UNP), and without wearing an exoskeleton (OFF). While following a confederate over obstacles at a constant pace, participants performed additional audio and visual tasks. Dependent measures included visual misses, visual reaction time, audio misses, audio reaction time, incremental lag time, and NASA-TLX scores. RESULTS The variability in the follow-task lag time was lowest with OFF and highest with UNP, highlighting reduced ability to maintain pace with the exoskeleton. Visual reaction time was significantly slower with PWR compared to OFF for 5 of 12 subjects. The NASA-TLX overall workload scores were lower for OFF compared to PWR and UNP. CONCLUSION Efforts to understand individual variability are warranted such that exoskeleton designs can be used for a wider set of the population. While not all subjects had measurable differences in the selected performance tasks, the perception of increased workload was present across subjects. It remains to be determined what difference in reaction time would be operationally relevant for task-specific settings. APPLICATION Findings draw attention to the need to consider "cognitive fit" and subject differences in the design and implementation of exoskeletons.
