Abstract

Objective
The need to augment of Walleye Sander vitreus populations may increase as these populations face challenges of changing habitats and climatic conditions. Since little has been published outside of agency reports on wild broodstocks, the intent of this study was to describe sex-specific Walleye spawning participation from a Great Plains broodstock operation. Specific objectives will assess standardization to collect target number of broodstock effort, catch per unit effort, and length and age participation of female and male broodstock.

Methods
Walleye were collected at Sherman Reservoir, Nebraska, during April spawn collection operations from 2015 to 2019. Gill nets were used to collect female Walleye, and boat electrofishing was used to collect male Walleye. Catch per effort was calculated for each sex, fish were measured to nearest 1-cm length-group, and a dorsal spine was taken from a subset of fish per length-group. Mean lengths and ages were calculated for each year of the study. Data were combined for all years of the project to display percent contribution by length and age.

Result
The amount of effort to capture 100 female and male Walleye varied by 4× and 2.5×, respectively, over the 5 years of sampling. Mean lengths and ages (±SE) of female (65 ± 1 cm; 10.4 ± 0.1 years) and male (43 ± 1 cm; 6.3 ± 0.1 years) Walleye collected were consistent during this study. The female Walleye collected represented 14 different ages, but ages 9–12 comprised 66% of all captured broodstock. The collected male Walleye also demonstrated age-compressed spawning tendencies, with ages 4–7 accounting for 74% of collected individuals that represented 13 different ages.

Conclusion
These results can define the anticipated variability in catch that can be expected at broodstock collection operations along with connection to specific lengths and ages of Walleye. Additionally, recognition that female and male Walleye broodstock contributions are consistently coming from four specific ages that are not the same year-classes may allow spawning operation staff to anticipate brood availability and ultimately improve the planning efficiency of these operations.

Abstract

Objective
Understanding the dynamic rate functions of introduced fish populations is essential in guiding management strategies. Blue Catfish Ictalurus furcatus population dynamics have been well studied; however, there is a gap in knowledge from populations that have been introduced into novel systems.

Methods
Blue Catfish were collected from the Altamaha, Ocmulgee, Oconee, and Satilla rivers in Georgia. Age estimates were obtained through otolith analysis. Multimodel growth analysis was used to describe growth patterns, and early life growth was modeled with linear regression. Instantaneous mortality of each population was estimated and compared by using a generalized linear model approach.

Result
The four introduced Blue Catfish populations exhibited rapid growth and low mortality rates during establishment; however, we found that populations with earlier introduction histories generally had slower growth rates and lower mortality. The Satilla River population is comparatively the most recently introduced population (first discovered in 2011) that exhibited the fastest growth and highest mortality.

Conclusion
Our results suggest that Blue Catfish in our study systems are in an intermediate stage of invasion and have not yet reached an equilibrium state. As density continues to increase in these river systems, we expect a decline in growth rates, delayed sexual maturation, and a greater observed maximum age. However, additional monitoring is needed to identify how population dynamics and reproductive characteristics vary over time.

ABSTRACTAimTo validate the Nurses' Global Assessment of Suicide Risk (NGASR) in Spanish for an early detection identification of the risk of suicide.DesignA descriptive cross‐sectional survey design was used for this work through face‐to‐face clinical interviews with each participant.MethodFollowing EQUATOR TRIPOD checklist, the index was translated and administered to a sample of 30 mental health experts and 151 university students. To examine the psychometric properties of the NGASR, the questionnaires also included other standardised scales such as BDI, SBQ and SEEQ. The research was conducted between 2022 and 2023.ResultsThe content validity index‐scale (CVI‐S) was 81% and the NGASR presented high reliability with a Kuder–Richardson coefficient of 0.83. Exploratory factor analysis (EFA) returned a six‐factor structure for the NGASR items. The results showed that 21.7% of the students assessed had an intermediate to very high suicide risk. This study also revealed that people with mental health problems and depression had a higher risk of suicide.Public ContributionBeyond the sociolinguistic Spanish validation of the scale, it should be noted that it is carried out on a young population in a nonclinical environment, something that many authors have been requesting in their previous validations. The NGASR is a useful prevention tool in university educational settings.

AbstractThe Xiaheqiadong site located in Zhangqiu district, Jinan city, Shandong province, China, was excavated in 2016 by the Jinan Institute of Archaeology, which revealed six single burials dating to the Beixin culture period (ca. 5,300–4,500 BC to ca. 4,100–3,600 BC). This paper used bioarchaeological methods to study the human skeletal remains to reconstruct the life course of the residents of the Beixin culture at the Xiaheqiadong site, focusing on stable isotope analysis, evaluation of stress, tooth ablation, and intentional skull modification. Based on stable isotope analysis of carbon, it is evident that the dietary structure of the ancient residents of Xiaheqiadong was mainly dependent on C4 plants or animals that ate mainly C4 plants. The stable isotope analysis of nitrogen indicated that the ancient residents of the Xiaheqiadong site exhibited a relatively sufficient consumption of animal protein. Furthermore, this result also reveals that a subsistence economic model was established consisting of farming, gathering, and hunting. Observations of the stress indicators (including cribra orbitalia, porotic hyperostosis, and linear enamel hypoplasia) revealed that they experienced poor health conditions and were under high levels of stress during infancy and early childhood. However, this situation improved with increasing age, suggesting that residents from the Xiaheqiadong site had the capacity to withstand severe living conditions and adapt after experiencing stress events. The tooth ablation and occipital modification cases from the Xiaheqiadong site are the earliest cases among the individuals with accurate dating results found in China.

AbstractThis study demonstrates a novel nanostructured drug delivery system utilizing α‐Fe2O3/CuO/CuFe2O4 ternary nanocomposite for effective drug transport in sick tissues. Centella Asiatica plant extract was employed to synthesize the Fe2O3/CuO/CuFe2O4 nanocomposite via sol‐gel auto combustion technique. The structural and morphological characteristics of the nanocomposite were investigated by XRD, FT‐IR, SEM, EDX, and VSM for magnetic properties. The XRD analysis demonstrates the successful synthesis of Fe2O3/CuO/CuFe2O4 nanocomposite with an average crystallite size of 18.393 nm. The antioxidant and antifungal capabilities of this nanocomposite were assessed for its biological activity. A notable inhibitory zone was observed when tested against the Alternaria spp. and Bipolaris sorokiniana fungi. An IC50 value of 109.88 μg/ml was found in the DPPH test, indicating that the nanocomposite exhibited remarkable antioxidant characteristics. Subsequently, metronidazole was encapsulated with a success rate of 55.53 % at pH 1.2, while at pH 7.4 it gained 57.83 %. The drug release of nanocomposite at pH 1.2 after 330 min was 43.41 % and at pH 7.4 after 300 min it was 52.3 %. The results indicate its potential as an excellent candidate for drug delivery. Furthermore, pH was found to be an effective catalyst in the drug loading and release processes.

AbstractThe benefits of tea consumption as a special diet for health and life satisfaction have attracted considerable attention; however, it is not clear whether the effect of tea consumption on self‐rated health (SRH) and self‐rated life satisfaction (SRL) is equal among all types of tea, and it is unclear whether these associations are impacted by gender and age in older adults. This study aimed to examine the associations between tea consumption, SRH and SRL in older adults and to explore the role of gender and age. Participants aged 65–105 (N = 78,345) were interviewed in the years 2002, 2005, 2008, 2011, 2014 and 2018 in the Chinese Longitudinal Healthy Longevity Study (CLHLS). Generalized estimation equations (GEE) with the identity link function were adopted to estimate the cross‐sectional associations of tea consumption with SRH and SRL. GEE with the logic link function were used to explore the longitudinal associations of tea consumption with SRH decline and SRL decline. Drinking tea at present, especially scented tea, was significantly associated with better SRH and SRL for older adults. Male participants benefited more from tea consumption than females, and the protective effect of green tea consumption on improving SRH and SRL in males was evident. Older adults aged 90–105 with current tea consumption daily had better SRH and reduced risk of SRL decline.

Published: October 2024

AbstractThe Geneva Sentimentality Scale (GSS) measures the experience of being moved and its effects on behavior. Despite the prevalence of this emotional response, it has not been extensively studied in China. This study aims to adapt and revise the GSS for Chinese college students to assess its cross‐cultural consistency. A sample of 1328 students aged 18–24 years participated in the study, with 127 randomly selected for retesting after an 8‐week interval. Exploratory factor analysis reveals that the Chinese version of the GSS includes three factors (emotional labels, tears of joy, and warm feelings in the chest), with a total of nine items. The internal consistency coefficients for the three factors and the overall scale are high, and the total score remains stable over time. Confirmatory factor analysis (CFA) shows that the three‐factor model has a good fit. Multigroup CFA indicates measurement invariance across genders. The results also demonstrate good discriminant and convergent validity for the scale. Overall, the GSS is a reliable and flexible tool for assessing the emotion of being moved among Chinese college students.
Picophytoplankton prevail year‐round in the Elbe estuary

Published: October 2024

AbstractPicophytoplankton are important primary producers, but not always adequately recognized, for example, due to methodological limitations. In this study, we combined flow cytometry and metabarcoding to investigate seasonal and spatial patterns of picophytoplankton abundance and community composition in the Elbe estuary. Due to the mixing of freshwater and seawater and the tidal currents this ecosystem is characterized by typical estuarine features such as salinity gradients and high turbidity. Picophytoplankton (mostly picoeukaryotes such as Mychonastes and Minidiscus) contributed on average 70% (SD = 14%) to the total phytoplankton counts. In summer picocyanobacteria (e.g., Synechococcus) played a more significant role. The contributions of picophytoplankton to the total phytoplankton were particularly high from summer to winter as well as in the mid estuary. However, at salinities of around 10 PSU in the mixing area of freshwater and seawater, the proportion of picophytoplankton was comparably low (average 49%, SD = 13%). Our results indicate that picophytoplankton prevail in the Elbe estuary year‐round with respect to cell counts. Picophytoplankton could occupy important niche positions to maintain primary production under extreme conditions where larger phytoplankton might struggle (e.g., at high or low temperature, high turbidity, and in areas with high grazing pressure) and also benefit from high nutrient availability here. However, we did not find evidence that they played a particularly significant role at the salinity interface. Our study highlights the importance of including picophytoplankton when assessing estuarine phytoplankton as has been suggested for other ecosystems such as oceans.

AbstractThis study investigates the potential of energy‐coupling factor (ECF) transporters as promising anti‐infective targets to combat antimicrobial resistance (AMR). ECF transporters, a subclass of ATP‐binding cassette (ABC) transporters, facilitate the uptake of B‐vitamins across bacterial membranes by utilizing ATP as an energy source. Vitamins are essential cofactors for bacterial metabolism and growth, and they can either be synthesized de novo or absorbed from the environment. These transporters are considered promising drug targets, underscoring the need for further research to harness their medicinal potential and develop selective inhibitors that block vitamin uptake in bacteria. Herein, we focused on the ECF transporter for pantothenate (vitamin B5) from Streptococcus pneumoniae and the ECF transporter for folate (vitamin B9) from Lactobacillus delbrueckii as a reference protein. We also included the energizing module for pantothenate along with both full transporter complexes. Initially, we transformed and purified the transporters, followed by an assessment of their thermal stability under various buffer composition, pH, and salt concentrations. Additionally, we monitored the melting temperature over six days to confirm their stability for further assays. We then measured the binding affinities of six ECF inhibitors using surface plasmon resonance (SPR) and evaluated their inhibitory effects through in vitro assays, including bacterial growth assay, whole‐cell uptake, and transport‐activity assays. After determining cytotoxicity in two human cell lines, we established an in vivo infection model using Galleria mellonella larvae to further validate our findings.

Published: October 2024

ABSTRACT‘Treatment effect measures under nonproportional hazards’ by Snapinn et al. (Pharmaceutical Statistics, 22, 181–193) recently proposed some novel estimates of treatment effect for time‐to‐event endpoints. In this note, we clarify three points related to the proposed estimators that help to elucidate their properties. We hope that their work, and this commentary, will motivate further discussion concerning treatment effect measures that do not require the proportional hazards assumption.

Published: October 2024

ABSTRACTThe high incidence and mortality rate of colorectal cancer have become a significant global health burden. Chemotherapy has been the traditional treatment for colorectal cancer and has demonstrated promising antitumor effects, leading to significant improvements in patient survival. However, the development of chemoresistance poses a major challenge during chemotherapy in colorectal cancer, significantly impeding treatment efficacy and affecting patient prognosis. Despite the development of a variety of novel anticolorectal cancer chemotherapy agents, their effectiveness and side effects vary, possibly due to the complex mechanisms of resistance in colorectal cancer. Abnormal drug metabolism or protein targets are the most direct causes of resistance. Further studies have revealed that these resistance mechanisms involve biochemical processes such as altered protein expression, autophagy, and epithelial–mesenchymal transitions. Herbal active ingredients offer an alternative treatment option and have shown promise in reversing colorectal cancer drug resistance. This paper aims to summarize the role of various biochemical processes and key protein targets in the occurrence and maintenance of resistance mechanisms in colorectal cancer. Additionally, it elaborates on the mechanisms of action of herbal active ingredients in reversing colorectal cancer drug resistance. The article also discusses the limitations and opportunities in developing novel anticolorectal cancer drugs based on herbal medicine.

Published: October 2024

AbstractUrban areas play an essential role in the global carbon balance, being responsible for more than 70% of anthropogenic carbon emissions, entering the atmosphere mainly in the form of carbon dioxide (CO2). Another crucial component of the carbon balance of the urban atmosphere is CO2 exchange with the biosphere, expressed in both emission and absorption fluxes. The biosphere component of the net CO2 flux is inseparably linked to the water (H2O) balance due to evapotranspiration. This article presents an estimation of CO2 and H2O net fluxes based on eddy covariance (EC) tower measurements and in‐depth analysis of its temporal and spatial variability for a typical urban site at mid‐latitude of the northern hemisphere. The source area was divided into two sectors, one representing dense urban development with sources of CO2 from traffic and households, and the second containing predominantly recreation and sports areas. Temporal variability analysis of evapotranspiration showed a clear seasonal cycle closely correlated with incoming radiation and air temperature, with the seasonal mean ranging from 0.4 mm·day−1 in winter to 1.6 mm·day−1 in summer. As a result of similar green coverage between the urban and green sectors, spatial variability was statistically insignificant. The net CO2 flux over a seasonal cycle was less pronounced for the total source area with a mean of 5.0 g C·m−2·day−1 in summer and 7.5 g C·m−2·day−1 in winter. However, significant variations between urban and green sectors were observed with the highest seasonal mean difference of 4.5 g C·m−2·day−1 in winter. The results confirm that while on the local, short time‐scale urban vegetation has a potential to mitigate the emissions, it is not able to offset them.
