    Abstract The lined sea anemone, Edwardsiella lineata, parasitizes the ctenophore Mnemiopsis leidyi, which is one of the most destructive marine invasive species in the world. Mnemiopsis leidyi is known to tolerate a wide range of environmental conditions. However, the environmental tolerances of its most prominent parasite have never been characterized. Here we determined the effects of temperature (18, 22, 26, and 30 C) and salinity (6, 15, 24, and 33 ppt) on the survival and development of E. lineata from a vermiform parasite to a free-living polyp. At higher temperatures and lower salinities, E. lineata experienced significantly higher mortality, and it failed to develop into an adult polyp at the highest temperature (30 C) and lowest salinities we tested (6 ppt or 15 ppt). While such temperature and salinity restrictions would not currently prevent E. lineata from infecting M. leidyi in many of the European waters where it has become a destructive invasive species, these environmental limitations may be reducing overlap between host and parasite within the host's native range, a situation that could be exacerbated by climate change.

    Abstract Corals are critical to marine biodiversity. Reproduction and dispersal are key to their resilience, but rarely quantified in nature. Exploiting a unique system-a fully censused, longitudinally characterized, semi-isolated population inhabiting mangroves-we used 2bRAD sequencing to demonstrate that rampant asexual reproduction most likely via parthenogenesis and limited dispersal enable the persistence of a natural population of thin-finger coral (

    Abstract Nematostella vectensis is a member of the phylum Cnidaria, a lineage that includes anemones, corals, hydras, and jellyfishes. This estuarine anemone is an excellent model system for investigating the evolution of stress tolerance because it is easy to collect in its natural habitat and to culture in the laboratory, and it has a sequenced genome. Additionally, there is evidence of local adaptation to environmental stress in different N. vectensis populations, and abundant protein-coding polymorphisms have been identified, including polymorphisms in proteins that are implicated in stress responses. N. vectensis can tolerate a wide range of environmental parameters, and has recently been shown to have substantial intraspecific variation in temperature preference. We investigated whether different clonal lines of anemones also exhibit differential tolerance to oxidative stress. N. vectensis populations are continually exposed to reactive oxygen species (ROS) generated during cellular metabolism and by other environmental factors. Fifteen clonal lines of N. vectensis collected from four different estuaries were exposed to hydrogen peroxide. Pronounced differences in survival and regeneration were apparent between clonal lines collected from Meadowlands, NJ, Baruch, SC, and Kingsport, NS, as well as among 12 clonal lines collected from a single Cape Cod marsh. To our knowledge, this is the first example of intraspecific variability in oxidative stress resistance in cnidarians or in any marine animal. As oxidative stress often accompanies heat stress in marine organisms, resistance to oxidative stress could strongly influence survival in warming oceans. For example, while elevated temperatures trigger bleaching in corals, oxidative stress is thought to be the proximal trigger of bleaching at the cellular level.

    Abstract Phylogenetic analysis enables one to reconstruct the functional evolution of proteins. Current understanding of NF-κB signaling derives primarily from studies of a relatively small number of laboratory models-mainly vertebrates and insects-that represent a tiny fraction of animal evolution. As such, NF-κB has been the subject of limited phylogenetic analysis. The recent discovery of NF-κB proteins in "basal" marine animals (e.g., sponges, sea anemones, corals) and NF-κB-like proteins in non-metazoan lineages extends the origin of NF-κB signaling by several hundred million years and provides the opportunity to investigate the early evolution of this pathway using phylogenetic approaches. Here, we describe a combination of bioinformatic and phylogenetic analyses based on menu-driven, open-source computer programs that are readily accessible to molecular biologists without formal training in phylogenetic methods. These phylogenetically based comparisons of NF-κB proteins are powerful in that they reveal deep conservation and repeated instances of parallel evolution in the sequence and structure of NF-κB in distant animal groups, which suggest that important functional constraints limit the evolution of this protein.

    Abstract The standard explanation for the origin of bilateral symmetry is that it conferred an advantage over radial symmetry for directed locomotion. However, recent developmental and phylogenetic studies suggest that bilateral symmetry may have evolved in a sessile benthic animal, predating the origin of directed locomotion. An evolutionarily feasible alternative explanation is that bilateral symmetry evolved to improve the efficiency of internal circulation by affecting the compartmentalization of the gut and the location of major ciliary tracts. This functional design principle is illustrated best by the phylum Cnidaria where symmetry varies from radial to tetraradial, biradial and bilateral. In the Cnidaria, bilateral symmetry is manifest most strongly in the internal anatomy and the disposition of ciliary tracts. Furthermore, the bilaterally symmetrical Cnidaria are typically sessile and, in those bilaterally symmetrical cnidarians that undergo directed locomotion, the secondary body axis does not bear a consistent orientation to the direction of locomotion as it typically does in Bilateria. Within the Cnidaria, the hypothesized advantage of bilateral symmetry for internal circulation can be tested by experimental analysis and computer modeling of fluid mechanics. The developmental evolution of symmetry within the Cnidaria can be further explored through comparative gene expression studies among species whose symmetry varies.

    Abstract Background: Minimally invasive thoracic surgery causes significant postoperative pain. Erector spinae plane (ESP) block and serratus anterior plane (SAP) block promise effective thoracic analgesia compared with systemically administered opioids, but have never been compared in terms of terms of quality of recovery and overall morbidity after minimally invasive thoracic surgery.
    Methods: Sixty adult patients undergoing minimally invasive thoracic surgery were randomly assigned to receive either single-shot ESP or SAP block before surgery using levobupivacaine 0.25%, 30 ml. The primary outcome was quality of patient recovery at 24 h, using the Quality of Recovery-15 (QoR-15) scale. Secondary outcomes included area under the curve (AUC) of pain verbal rating scale (VRS) over time, time to first opioid analgesia, postoperative 24 h opioid consumption, in-hospital comprehensive complication index (CCI) score and hospital stay.
    Results: The QoR-15 score was higher among ESP patients compared with those in the SAP group, mean (standard deviation): 114 (16) vs 102 (22) (P=0.02). Time (min) to first i.v. opioid analgesia in recovery was 32.6 (20.6) in ESP vs 12.7 (9.5) in SAP (P=0.003). AUC at rest was 92 (31) mm h
    Conclusion: Compared with SAP, ESP provides superior quality of recovery at 24 h, lower morbidity, and better analgesia after minimally invasive thoracic surgery.

    Abstract Objective: We aimed to determine if there is an optimal time to complete dedicated research during surgical residency.
    Background: Research is an integral part of academic general surgical residency, and dedicated research usually occurs after the 2nd or 3rd post-graduate year (PGY). The timing of dedicated research and its association with resident productivity, self-assessed competency (including technical skills), and fellowship match is not known.
    Methods: PubMed was queried for publications resulting after dedicated research time for graduating surgical residents at a single institution from 2010 to 2021. Graduates were surveyed about their research experience and placed into 2 groups: research after PGY2 or PGY3.
    Results: Sixty-six of 91 (73%) graduating residents completed dedicated research (after PGY2, n=28; after PGY3, n=38). Median number of total and first author publications was similar between groups; however, research after PGY2 was associated with an increased number of basic science publications by fellowship application deadlines (PGY2: 1.0[0-13] vs PGY3: 0.0[0-6], p=0.02). With a 79% survey response rate, there were no differences in self-assessed competencies upon return from research between cohorts. Most surveyed residents matched at their top fellowship choice (PGY2:70% vs PGY3:62%, p=0.77).
    Conclusions: Research after PGY2 or PGY3 had no association with residents' total number of publications, self-assessed competency, or rates of matching at first choice fellowship. As research after PGY2 had an increased number of basic science publications by time of fellowship application, surgical residents applying to fellowships that highly value basic science research may benefit from completing dedicated research after PGY2.

    Abstract AbstractAs coral reefs experience dramatic declines in coral cover throughout the tropics, there is an urgent need to understand the role that non-reef habitats, such as mangroves, play in the ecological niche of corals. Mangrove habitats present a challenge to reef-dwelling corals because they can differ dramatically from adjacent reef habitats with respect to key environmental parameters, such as light. Because variation in light within reef habitats is known to drive intraspecific differences in coral phenotype, we hypothesized that coral species that can exploit both reef and mangrove habitats will exhibit predictable differences in phenotypes between habitats. To investigate how intraspecific variation, driven by either local adaptation or phenotypic plasticity, might enable particular coral species to exploit these two qualitatively different habitat types, we compared the phenotypes of two widespread Caribbean corals,

    Abstract Bilateral symmetry is a hallmark of the Bilateria. It is achieved by the intersection of two orthogonal axes of polarity: the anterior-posterior (A-P) axis and the dorsal-ventral (D-V) axis. It is widely thought that bilateral symmetry evolved in the common ancestor of the Bilateria. However, it has long been known that members of the phylum Cnidaria, an outgroup to the Bilateria, also exhibit bilateral symmetry. Recent studies have examined the developmental expression of axial patterning genes in members of the phylum Cnidaria. Hox genes play a conserved role in patterning the A-P axis of bilaterians. Hox genes are expressed in staggered axial domains along the oral-aboral axis of cnidarians, suggesting that Hox patterning of the primary body axis was already present in the cnidarian-bilaterian ancestor. Dpp plays a conserved role patterning the D-V axis of bilaterians. Asymmetric expression of dpp about the directive axis of cnidarians implies that this patterning system is similarly ancient. Taken together, these result imply that bilateral symmetry had already evolved before the Cnidaria diverged from the Bilateria.
