- Speciated particle-phase organic nitrates (pONs) were quantified using online chemical ionization MS during June and July of 2013 in rural Alabama as part of the Southern Oxidant and Aerosol Study. A large fraction of pONs is highly functionalized, possessing between six and eight oxygen atoms within each carbon number group, and is not the common first generation alkyl nitrates previously reported. Using calibrations for isoprene hydroxynitrates and the measured molecular compositions, we estimate that pONs account for 3% and 8% of total submicrometer organic aerosol mass, on average, during the day and night, respectively. Each of the isoprene- and monoterpenes-derived groups exhibited a strong diel trend consistent with the emission patterns of likely biogenic hydrocarbon precursors. An observationally constrained diel box model can replicate the observed pON assuming that pONs (i) are produced in the gas phase and rapidly establish gas-particle equilibrium and (ii) have a short particle-phase lifetime (∼2-4 h). Such dynamic behavior has significant implications for the production and phase partitioning of pONs, organic aerosol mass, and reactive nitrogen speciation in a forested environment.

- Background: A precise and consistent definition of return to sport (RTS) after anterior cruciate ligament (ACL) injury is lacking, and there is controversy surrounding the process of returning patients to sport and their previous activity level. Purpose: The aim of the Panther Symposium ACL Injury Return to Sport Consensus Group was to provide a clear definition of RTS after ACL injury and a description of the RTS continuum as well as provide clinical guidance on RTS testing and decision-making. Study Design: Consensus statement. Methods: An international, multidisciplinary group of ACL experts convened as part of a consensus meeting. Consensus statements were developed using a modified Delphi method. Literature review was performed to report the supporting evidence. Results: Key points include that RTS is characterized by achievement of the preinjury level of sport and involves a criteria-based progression from return to participation to RTS and, ultimately, return to performance. Purely time-based RTS decision-making should be abandoned. Progression occurs along an RTS continuum, with decision-making by a multidisciplinary group that incorporates objective physical examination data and validated and peer-reviewed RTS tests, which should involve functional assessment as well as psychological readiness. Consideration should be given to biological healing, contextual factors, and concomitant injuries. Conclusion: The resultant consensus statements and scientific rationale aim to inform the reader of the complex process of RTS after ACL injury that occurs along a dynamic continuum. Research is needed to determine the ideal RTS test battery, the best implementation of psychological readiness testing, and methods for the biological assessment of healing and recovery.

- THE EFFECT OF VARYING THE STIMULUS INTENSITY (LOUDNESS) ON THE RECALL OF 9-DIGIT SEQUENCES WAS STUDIED USING 2 PRESENTATION RATES. AT 1 DIGIT/SEC AND WITH INSTRUCTIONS FOR 3, 3, AND 3 REHEARSAL GROUPING, STIMULUS INTENSITY WAS FOUND TO BE A VARIABLE ONLY IN THE CASE OF THE LAST 3 DIGITS, WHICH ACCORDING TO REHEARSAL INSTRUCTIONS WERE UNREHEARSED. NO EFFECT WAS FOUND ON THE 1ST 6 REHEARSED DIGITS. AT 4 DIGITS/SEC, A RATE TOO FAST FOR SYSTEMATIC REHEARSAL, THE STIMULUS INTENSITY AFFECTED THE RECALL OF THE 1ST 6 AND THE LAST 3 DIGITS. THE RESULTS ARE DISCUSSED IN RELATION TO THE QUESTION OF WHETHER OR NOT THE STIMULUS AND REHEARSAL MEMORY TRACES SHOULD BE REGARDED SEPARATELY. THE QUESTION OF PRESENTATION RATE AND PERFORMANCE IS ALSO DISCUSSED.

- Quality of life is a key outcome that is not rigorously measured in obesity treatment research due to the lack of standardization of patient-reported outcomes (PROs) and PRO measures (PROMs). The S.Q.O.T. initiative was founded to Standardize Quality of life measurement in Obesity Treatment. A first face-to-face, international, multidisciplinary consensus meeting was conducted to identify the key PROs and preferred PROMs for obesity treatment research. It comprised of 35 people living with obesity (PLWO) and healthcare providers (HCPs). Formal presentations, nominal group techniques, and modified Delphi exercises were used to develop consensus-based recommendations. The following eight PROs were considered important: self-esteem, physical health/functioning, mental/psychological health, social health, eating, stigma, body image, and excess skin. Self-esteem was considered the most important PRO, particularly for PLWO, while physical health was perceived to be the most important among HCPs. For each PRO, one or more PROMs were selected, except for stigma. This consensus meeting was a first step toward standardizing PROs (what to measure) and PROMs (how to measure) in obesity treatment research. It provides an overview of the key PROs and a first selection of the PROMs that can be used to evaluate these PROs.

Multiple spectral channels in branchiopods. I. Vision in dim light and neural correlates

- Animals that have true color vision possess several spectral classes of photoreceptors. Pancrustaceans (Hexapoda+Crustacea) that integrate spectral information about their reconstructed visual world do so from photoreceptor terminals supplying their second optic neuropils, with subsequent participation of the third (lobula) and deeper centers (optic foci). Here, we describe experiments and correlative neural arrangements underlying convergent visual pathways in two species of branchiopod crustaceans that have to cope with a broad range of spectral ambience and illuminance in ephemeral pools, yet possess just two optic neuropils, the lamina and the optic tectum. Electroretinographic recordings and multimodel inference based on modeled spectral absorptance were used to identify the most likely number of spectral photoreceptor classes in their compound eyes. Recordings from the retina provide support for four color channels. Neuroanatomical observations resolve arrangements in their laminas that suggest signal summation at low light intensities, incorporating chromatic channels. Neuroanatomical observations demonstrate that spatial summation in the lamina of the two species are mediated by quite different mechanisms, both of which allow signals from several ommatidia to be pooled at single lamina monopolar cells. We propose that such summation provides sufficient signal for vision at intensities equivalent to those experienced by insects in terrestrial habitats under dim starlight. Our findings suggest that despite the absence of optic lobe neuropils necessary for spectral discrimination utilized by true color vision, four spectral photoreceptor classes have been maintained in Branchiopoda for vision at very low light intensities at variable ambient wavelengths that typify conditions in ephemeral freshwater habitats.

Memory for Action : A Distinct Form of Episodic Memory?
- 2001. - 1
-
Bok (refereegranskat)abstract
- The book presents in eight chapters our actual knowledge on memory for actions and it gives room to the proponents of the opposing models to develop their view for explaining action memory. In Chapter one, Hubert Zimmer and Ronald Cohen summarize the results of laboratory research on action, i. e. memory for self-performed actions. In Chapter two, Melissa Guynn, Mark McDaniel and Gilles Einstein extend this field on memory for intended actions. They present their view on the prospective memory of actions, and they demonstrate the importance of automatic retrieval in prospective memory. In the following chapter, Johannes Engelkamp presents his motor oriented explanation of action memory. He claims that output processes strongly contribute to memory for performed actions, and that the information which is critical for memory is closely related to the information used in the motor control of overt performance. Reza Kormi-Nouri and Lars-Göran Nilsson (Chapter four) completely disagree with this position. They argue that performing actions may cause specific processes, but that nevertheless action memory is part of a unique episodic memory which stores all types of episodes in a similar way. In the following chapter, Mary Ann Foley and Hilary Ratner put action memory in the broader context of activity memory. Everyday actions are usually performed in social contexts and they are goal-oriented. This aspect is seldom relevant in laboratory research, but the authors show that it is of importance for everyday memory. Then two brief chapters follow in which Nilsson and Kormi-Nouri on the one hand, and Engelkamp on the other hand mutually comment on each others position. In the closing chapter, Hubert Zimmer discusses the presented different attempts in parallel. He is doing this by taking into account the different processes and brain modules which are necessary for a successful control of actions.
