Restored Oyster Reef Location and Design Affect Responses of Resident and Transient Fish, Crab, and Shellfish Species in Mobile Bay, Alabama
Authors: Gregalis Kevan C. , Johnson Matthew W. , Powers Sean P. 
Published: March 2009

AbstractRecent efforts to restore oyster reefs have resulted in the creation of many reefs with the explicit objective of benefiting local shellfish and finfish fisheries. We evaluated the community responses of the fish (transient and resident), crab, and shellfish species that colonized or utilized a series of restored high‐ and low‐relief oyster reefs at three different locations within Mobile Bay, Alabama. Sites were chosen to represent different combinations of sediment type, proximity to established oyster reefs, water quality, and water movement patterns. The results showed substantial differences in reef community among the three sites and, compared with unstructured bottoms, increased abundance of several species of small demersal fishes and sessile invertebrates. Common mud crabs Panopeus herbstii and flatback mud crabs Eurypanopeus depressus were the only species to exhibit any consistent patterns in habitat use that could be directly attributed to reef height. The species composition of transient fishes did vary among treatments, but the total abundance on low‐relief reefs and unstructured control areas was similar and often greater than that on high‐relief reefs. There were significant two‐way interactions between season, reef location, and reef design for most species abundances. These results suggest that the responses by resident and transient species to reef restoration were highly variable and that our ability to predict the community responses of resident and transient fishes to oyster reef restoration may be limited because of the interactions among location‐specific biophysical characteristics.

Published: March 2009

This paper proposes a rapid dynamic analysis method for microgyroscope using system vibration modes to solve the problems concerning to the computing time in the performance analysis of microgyroscope. The results of eigenvalue solution are employed to construct the state space model. The response of the microgyros	cope can be reconstructed as a response superposition of the vibration modes, and then the system equation is decoupled into an uncoupled equation. The dynamic response of the microgyroscope can be calculated by a simple superposition.

AbstractColorectal cancer (CRC) is a heterogenous malignancy and research is focused on identifying novel ways to subtype patients. In this study, a novel classification system, tumour microenvironment score (TMS), was devised based on Klintrup–Mäkinen grade (KMG), tumour stroma percentage (TSP), and tumour budding. TMS was performed using a haematoxylin and eosin (H&E)‐stained section from retrospective CRC discovery and validation cohorts (n = 1,030, n = 787). TMS0 patients had high KMG, TMS1 were low for KMG, TSP, and budding, TMS2 were high for budding, or TSP and TMS3 were high for TSP and budding. Scores were assessed for association with survival and clinicopathological characteristics. Mutational landscaping and Templated Oligo‐Sequencing (TempO‐Seq) profiling were performed to establish differences in the underlying biology of TMS. TMS was independently prognostic in both cohorts (p < 0.001, p < 0.001), with TMS3 predictive of the shortest survival times. TMS3 was associated with adverse clinical features including sidedness, local and distant recurrence, higher T stage, higher N stage, and presence of margin involvement. Gene set enrichment analysis of TempO‐Seq data showed higher expression of genes associated with hallmarks of cancer pathways including epithelial to mesenchymal transition (p < 0.001), IL2 STAT5 signalling (p = 0.007), and angiogenesis (p = 0.017) in TMS3. Additionally, enrichment of immunosuppressive immune signatures was associated with TMS3 classification. In conclusion, TMS represents a novel and clinically relevant method for subtyping CRC patients from a single H&E‐stained tumour section.

AbstractObjectiveThe pathological features of immune‐mediated necrotizing myopathy (IMNM) are dominated by the infiltration of macrophages. We aimed to perform a histopathologic semiquantitative analysis to investigate the relationship between macrophage markers and prognosis.MethodsSemiquantitative analysis of histologic features was performed in 62 samples of IMNM. Independent risk factors were identified through univariate and multivariate regression analysis. Cluster analysis was performed using the partitioning around the medoids (PAM) method. Decision tree modeling was utilized to efficiently determine cluster labels for IMNM patients. The validity of the developmental cohort was assessed by accuracy in comparison with the validation cohort.ResultsThe most enriched groups in patients with IMNM were macrophages expressing CD206 and CD163. In the multivariate logistic regression model, the high density of CD163+ macrophages in perimysial connective tissue increased the risk of unfavorable prognosis (p = 0.025, OR = 1.463, 95% CI: 1.049–2.041). In cluster analysis, patients in Cluster 1, with lower CD163+ macrophage density and inflammatory burden, had a more favorable prognosis. Conversely, patients in Cluster 3, which were enriched for CD163+ macrophages in the perimysial connective tissue, had the most severe clinical features and the worst prognosis. Correlations were found between the density of CD163+ macrophages in connective tissue and symptom duration (R2 = 0.166, p < 0.001), dysphagia (p = 0.004), cardiac involvement (p = 0.021), CK (R2 = 0.067, p = 0.042), CRP (R2 = 0.117, p < 0.001), and ESR (R2 = 0.171, p < 0.001).ConclusionThe density of CD163+ macrophages in perimysial connective tissue may serve as a potential marker for the prediction of IMNM prognosis.

AbstractThe sensing of small molecules is important to a variety of fields and particularly to clinical diagnostics. Estriol is an important small chemical molecule, as it is one of three markers measured during mid‐gestation for the Down syndrome. Point‐of‐care testing of estriol will increase maternal compliance for aneuploidy mid‐gestation screening. A bioFET technology is a promising point‐of‐care platform. The meta‐nano‐channel (MNC) bioFET is employed with its tunable channel configuration to optimize the coupling between the electrostatics of the estriol‐receptor interactions and the electrodynamics of the conducting readout current. Also, the MNC bioFET receptor layer is composed of anti‐estriol antibodies to address the high structural similarity of estriol to other estrogens. Despite the small size and the electrical neutrality of estriol, real‐time is demonstrated, specific, and label‐free sensing of estriol in 0.5 µL of 1:100 diluted plasma with excellent linearity, sensitivity, dynamic range extending to ten orders of magnitude in estriol concentration and limit‐of‐detection of 1 fg mL−1. Extensive control and non‐specific measurements are reported including the response to other neutral members of the estrogen family.

Published: April 2024

AbstractCarbon dots (CDs) are an interesting nanomaterial due to their tunable photoluminescence and other functional properties. Herein, by introducing amine‐functionalized CDs nanoparticles onto macromolecular chains of maleic anhydride grafted styrene‐ethylene‐butylene‐styrene (SEBS‐g‐MA) via a possible ring‐opening reaction of anhydride with amine, a mechanically robust and ultrastretchable thermoplastic elastomeric materials with fluorescence and dielectric functionality was developed. The amine‐functionalized CDs nanoparticles were synthesized from pyrene precursor by hydrothermal treatment. The transmission electron micrograph, Raman, Fourier transform infrared, and x‐ray photoelectron spectra confirmed the formation of highly crystalline graphitized structure of the CDs nanoparticles. Fluorescence and UV–Vis spectroscopy were used to evaluate the optical properties of the developed materials. The developed CDs/SEBS‐g‐MA nanocomposites exhibited strong intense green fluorescence compared with the pure SEBS‐g‐MA film. The thermal stability of the developed nanocomposites was improved by an increase of the Tmax by about 18°C. In addition, the developed composite showed high stretchability (strain at break ~1000%), good mechanical strength, and dielectric properties (room temperature dielectric constant ~5.2). The enhanced dielectric property of the developed composites may be due to the space charge accumulation and induced interfacial polarization at the filler–matrix interface.

AbstractThe synthesis of gold nanoparticles reinforced functionalized single‐walled/multi‐walled carbon nanotubes nanohybrid based polyaniline nanocomposites were carried out using in situ polymerization. The chemical interaction and nanostructured morphology of the synthesized nanocomposites are studied using ultraviolet–visible spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, x‐ray diffraction analysis, x‐ray photoelectron spectroscopy, and field emission scanning electron microscopy. Thermal stability of synthesized PANI/Au@f‐SWNTs is boosted by a magnitude of 30°C as compared with the pristine PANI matrix, which is attributed to a strong barrier effect because of the development of tortuous path that resulted from a uniform distribution of Au@f‐CNTs throughout the PANI matrix. For PANI/Au@f‐SWNTs, the AC conductivity and dielectric permittivity are improved by a value of 83.58 S/cm and 1.35 × 10−5 as well as the dielectric loss is reduced by a factor of 0.11 in comparison with the pure PANI matrix at an applied frequency of 106 Hz. PANI/Au@f‐SWNTs and PANI/Au@f‐MWNTs ternary nanocomposites exhibited excellent selectivity toward the hazardous Cr(VI) heavy metal ions in an aqueous medium with a limit of detection of 0.74 and 0.89 μM with a binding constant of 1.028 × 105 and 3.46 × 104 M−1, respectively, that can be selective and sensitive for the detection of Cr(VI) metal ions in water at trace level.

AbstractThe non‐biodegradability of Ethylene‐Propylene Side‐by‐Side (ES) fibers has led to significant environmental pollution from waste sanitary products, thereby posing a severe challenge to the environment. Replacing traditional non‐biodegradable materials with biodegradable polymeric materials is the most effective method to achieve a green environment. In this study, core‐sheath fibers composed of biodegradable poly (butylene adipate‐co‐terephthalate) (PBAT) as the sheath layer and polylactic acid (PLA) as the core layer were fabricated. The effects of different viscosity ratios and the composite ratios of sheath and core on the structure and performance of the resultant core‐sheath fibers were investigated in detail. The results showed that when the PBAT/PLA composite ratio is 50:50 and the viscosity ratio range from 0.8 to 1.43, the PBAT/PLA core‐sheath composite fibers exhibit good spinnability and a complete core‐sheath structure, with their tensile properties comparable to those of PP/PE core‐sheath composite fibers. Further research found that when the viscosity ratio was 1.00 and the PLA component content in the PBAT/PLA composite fibers increased from 40% to 60%, the fibers still maintained good spinnability and a complete core‐sheath structure. In addition, when the PBAT/PLA composite ratio was 60:40, after 120 days of biodegradation, its strength retention rate was only 35.2%.

Published: April 2024

AbstractThe work aims to develop and optimize a powdered phytopharmaceutical product from the stem bark of Hymenaea courbaril L. (jatobá) by the spouted bed drying. The study commenced with the extraction of bioactive compounds present in the plant raw material by dynamic maceration using ethanol/water 70% (v/v) at a temperature of 50°C for 60 min, for the ratio stem bark: solvent mass of 1:10 (w/w). The extract quality was assessed by quantifying chemical markers via spectrophotometry (total polyphenols and tannins) and through antioxidant activity by 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) assay. The extractive solution was concentrated, added with drying adjuvant, and submitted to spouted bed drying. Product quality was evaluated by moisture content (Xp), water activity (aW), powder diameter, total polyphenols, and tannins content (PT and TT), and antioxidant activity, expressed as the extract concentration needed to reduce 50% of the DDPH radical (IC50). Spouted bed drying performance was evaluated through the drying yield (REC), product accumulation (Ac), and thermal efficiency (η). The optimal processing conditions were: inlet gas temperature, Tgi: 150°C, the ratio of the mass feed flow rate of the concentrated extract to the evaporation capacity of the dryer, Ws/Wmax: 45%, and the drying gas flow rate relative to minimum spouting, Q/Qms: 1.85. Under these conditions, it is predicted to obtain a dried extract with Xp = 4.9% w/w, PT = 26.0% w/w, REC = 77.7% w/w, η = 44.3%, and Ac = 10% w/w, with adequate values of aW, TT, and high antioxidant activity.

AbstractA series of methoxylated bis(pentafluorophenyl)boron‐β‐diketonates (dkB(C6F5)2) with intense emission has been synthesized and characterized by a variety of physicochemical methods. The photophysical properties of the synthesized compounds were thoroughly investigated by electronic absorption, steady‐state, and time‐resolved fluorescence spectroscopy in both solution and solid state. The studied compounds exhibit solvatochromic behavior attributed to the intramolecular charge transfer (ICT) nature of the first excited state. The formation of exciplexes between DBMB(C6F5)2 and benzene derivatives was also studied. Notably, the studied compounds display a complex luminescence profile in the solid state, featuring fluorescence, delayed fluorescence and phosphorescence emission. Furthermore, the hydrolytical stability of the complexes was assessed, demonstrating excellent resistance to hydrolysis. Estimated rate constants, determined at 60 °C, are significantly lower (90‐2000 times) than those observed for the well‐studied dibenzoylmethanatoboron difluoride (DBMBF2). The incorporation of pentafluorophenyl substituents at the boron atom enables the synthesis of highly fluorescent and hydrolytically stable boron chelate complexes, suitable for sensing and bioimaging applications in water‐containing environments.
Prevalence of non 16/18 high risk human papilloma virus as a quality metric in gynecological cytology

Published: April 2024

AbstractHuman papillomavirus (HPV) is the most common sexually transmitted pathogen that causes anogenital disease. Cervical screening by cytology and HPV testing (co‐testing) are important in prevention of cervical cancer. The Bethesda System category of atypical squamous cells (ASC) is used when a neoplastic process cannot be confidently identified. In such cases, the differential diagnosis is broad and includes benign conditions. Monitoring of ASC/SIL ratio is a commonly used laboratory quality assurance measure to prevent over‐ or under‐use of this category. High risk human papillomavirus (hr‐HPV) has been used in conjunction with the ASC/SIL ratio in determining whether a particular pathologist is over/under‐using the indefinite category. However, the laboratory overall sample population prevalence rate of hr‐HPV subtypes has not been previously examined for association with the ASC rate. In this study, the relationships between ASC/SIL ratio and hr‐HPV prevalence rate and hr‐HPV subtypes (16/18 and non‐16/18) to the laboratory ASC prevalence were studied. The results demonstrate that HPV non‐16/18 is the main subtype which is associated with ASC‐US category. A large proportion of non‐16/18 HPV‐related cases are seen in young patients, which largely abates by the by fourth decade. In addition, there are differences in the ASC/SIL ratio for HPV 16/18 and non‐16/18 types. The overall ASC/SIL ratio is an average of the ASC/SIL rate for the non‐16/18 population and the HPV 16/18 population. Instead of basing the laboratory and practitioners' quality indicator solely on ASC/SIL ratio, the overall prevalence of HPV and its subtype ratio should also be reported as they are more reflective of laboratory performance.
Highly diverse cuticular hydrocarbon profiles but no evidence for aggression towards non‐kin in the ambrosia beetle Xyleborinus saxesenii

AbstractAnimal societies use nestmate recognition to protect against social cheaters and parasites. In most social insect societies, individuals recognize and exclude any non‐nestmates and the roles of cuticular hydrocarbons as recognition cues are well documented. Some ambrosia beetles live in cooperatively breeding societies with farmed fungus cultures that are challenging to establish, but of very high value once established. Hence, social cheaters that sneak into a nest without paying the costs of nest foundation may be selected. Therefore, nestmate recognition is also expected to exist in ambrosia beetles, but so far nobody has investigated this behavior and its underlying mechanisms. Here we studied the ability for nestmate recognition in the cooperatively breeding ambrosia beetle Xyleborinus saxesenii, combining behavioural observations and cuticular hydrocarbon analyses. Laboratory nests of X. saxesenii were exposed to foreign adult females from the same population, another population and another species. Survival as well as the behaviours of the foreign female were observed. The behaviours of the receiving individuals were also observed. We expected that increasing genetic distance would cause increasing distance in chemical profiles and increasing levels of behavioural exclusion and possibly mortality. Chemical profiles differed between populations and appeared as variable as in other highly social insects. However, we found only very little evidence for the behavioural exclusion of foreign individuals. Interpopulation donors left nests at a higher rate than control donors, but neither their behaviours nor the behaviours of receiver individuals within the nest showed any response to the foreign individual in either of the treatments. These results suggest that cuticular hydrocarbon profiles might be used for communication and nestmate recognition, but that behavioural exclusion of non‐nestmates is either absent in X. saxesenii or that agonistic encounters are so rare or subtle that they could not be detected by our method. Additional studies are needed to investigate this further.
