Authors: Chen Liangbin , Zhao Lihong , Ding Keren 
Published: September 2023

Purpose
This paper aims to improve the permeability and antifouling of polysulfone (PSF) ultrafiltration membranes, the PSF matrix was modified by incorporating sulfonated polysulfone (SPSF).

Design/methodology/approach
Systematic investigations were conducted on the synergistic effects of a pore-forming agent, coagulation bath temperature and SPSF doping in the casting solution on blended ultrafiltration membranes. The chemical composition of the membranes was analyzed using Fourier transform infrared spectroscopy. The morphology and surface roughness of the membranes were characterized using scanning electron microscopy and atomic force microscopy. The hydrophilicity of the membrane surface was analyzed using a contact angle meter. The permeability and antifouling properties of the blended membranes were also investigated through filtration experiments.

Findings
The results indicated that the blended ultrafiltration membranes demonstrated an optimal overall performance when PVP-K30 content was 5.0 Wt.%, coagulation bath temperature was 30°C and SPSF content was 2.4 Wt.%. In comparison to a pure PSF ultrafiltration membrane, there was a significant increase in pure water flux (390.7 L·m−2·h−1) by 2.2 times, while bovine serum albumin retention slightly decreased to 93.8%. In addition, the flux recovery rate improved by 2.1 times (71.4%) compared to that of the original PSF ultrafiltration membrane.

Practical implications
The method provided a simple and practical solution for improving the antifouling and permeability of PSF ultrafiltration membranes.

Originality/value
SPSF was anticipated to serve as an excellent modification additive for the preparation of ultrafiltration membranes with superior properties.

Published: September 2023

Purpose
Social media (SM) networks offer a golden opportunity for firms that particularly engage in international activities to set up sustainable customer relationships and improve competitiveness. The purpose of this study is to examine the influence of SM adoption on the export intensity (EI) of firms listed on Borsa Istanbul (BIST) for the years 2010–2020. The authors use social media index (SMI) to measure SM adoption and firm size (FSize) as a moderator on exploring the interaction of SM and EI.

Design/methodology/approach
Using a sample of 150 firms listed on the BIST Industrials Index, this study explores how the adoption of SM affects EI by using panel data analysis over the period of 2010–2020.

Findings
The results indicate that the SMI has a positive and significant effect on the EI. FSize positively moderates the interaction of SMI and EI, indicating that large firms benefit more from the SM in increasing export performance. The findings reflect high potential of EI improvement through adopting right SM policies in emerging markets.

Research limitations/implications
The sample covers only public companies listed on the BIST Industrials Index. Future studies may extend the coverage and include multiple emerging markets to draw generalized results for the export-oriented firms. This research also analyzes solely four SM networks, i.e. Facebook, Instagram, Twitter and YouTube. However, there are many other SM networks that firms use in online marketing in foreign markets. Finally, this research did not discuss the potential factors that could influence the use of SM in emerging market firms.

Practical implications
This study denotes the significant role of SM adoption on the EI of firms in an emerging market setting from the perspective of resource-based view. It presents an insightful approach in understanding the mission played by SM networks in enhancing the EI of Turkish firms. Policymakers may use the findings to develop public support programs to promote the adoption and implementation of the SM among exporting firms in emerging markets.

Originality/value
The study provides evidence on the effects of SM adoption on the EI from the perspective of emerging countries. It also helps to gain a deeper understanding of how different SM platforms contribute to the internationalization of firms.
Sports consumption behaviors of football fans: the relationship between social identity, team loyalty and behavioral intention toward consumption
Authors: Kural Sercan , Özbek Oğuz 
Published: September 2023

PurposeThe study aimed to establish football fans' levels of social identity, team loyalty, and behavioral intentions toward sports consumption and to determine the relationship between these variables using a structural equation model.Design/methodology/approachResearch methods: The research model was tested by data analysis using AMOS 23.0. The study sample included 518 football fans with mean age 30.87 (±10.15) years. Data were collected using an online questionnaire delivered to football fans via social media.FindingsThe results supported the study hypotheses and showed that social identity and team loyalty had a significant effect on behavioral intention toward sport consumption for football teams. Social identity was found to have a direct effect on sport consumption behaviors. It was further established that team loyalty was a mediator in the relationship between the fans' social identity and behavioral intention toward sports consumption.Research limitations/implicationsThe study planned to collect the data at the stadium entrance before the game; however, it was not possible to reach the fans face-to-face due to the COVID-19 pandemic, and therefore, the data were collected online.Practical implicationsBy understanding how the extent of social identity affects sports consumption intention, sports club managers can achieve a higher level of fan loyalty to their teams.Social implicationsThe present study provides additional insight into the available literature on team identification. It demonstrated that team identification was associated with social identity and that social identity had an impact on sports consumption behaviors.Originality/valueThis study is an original study in that it is a study in which the social identity scale is used together with the variables of team loyalty and sports consumption behavior intention. The findings of this study help understand the processes that shape the behavioral intentions of football fans toward sports consumption. Furthermore, the mediating role of the developed model was tested using team loyalty.

Abstract

Animals interact with and impact ecosystem biogeochemical cycling—processes known as zoogeochemistry. While the deposition of various animal materials (e.g. carcasses and faeces) has been shown to create nutrient hotspots and alter nutrient cycling and storage, the inputs from parturition (i.e. calving) have yet to be explored. We examine the effects of ungulate parturition, which often occurs synchronously during spring green‐up and therefore aligns with increased plant nitrogen demand in temperate biomes.

Impacts of zoogeochemical inputs are likely context‐dependent, where differences in material quality, quantity and the system of deposition modulate their impacts. Plant mycorrhizal associations, especially, create different nutrient‐availability contexts, which can modify the effects of nutrient inputs. We, therefore, hypothesize that mycorrhizal associations modulate the consequences of parturition on soil nutrient dynamics and nitrogen pools.

We established experimental plots that explore the potential of two kinds of zoogeochemical inputs deposited at ungulate parturition (placenta and natal fluid) in forest microsites dominated by either ericoid mycorrhizal (ErM) or ectomycorrhizal (EcM) plants. We assess how these inputs affect rates of nutrient cycling and nitrogen content in various ecosystem pools, using isotope tracers to track the fate of nitrogen inputs into plant and soil pools.

Parturition treatments accelerate nutrient cycling processes and increase nitrogen contents in the plant leaf, stem and fine root pools. The ecosystem context strongly modulates these effects. Microsites dominated by ErM plants mute parturition treatment impacts on most nutrient cycling processes and plant pools. Both plant–fungal associations are, however, equally efficient at retaining nitrogen, although retention of nitrogen in the parturition treatment plots was more than two times lower than in control plots.

Our results highlight the potential importance of previously unexamined nitrogen inputs from animal inputs, such as those from parturition, in contributing to fine‐scale heterogeneity in nutrient cycling and availability. Animal inputs should therefore be considered, along with their interactions with plant mycorrhizal associations, in terms of how zoogeochemical dynamics collectively affect nutrient heterogeneity in ecosystems.

AbstractObjectiveTo investigate the use of menopausal hormone therapy (MHT) in premenopausal women after bilateral oophorectomy.DesignRetrospective register‐based cohort study.SettingSweden.PopulationSwedish women aged 35–44 years without malignancy who underwent bilateral oophorectomy in 2005–2020 were identified using The Swedish National Quality Register of Gynaecological Surgery (GynOp).MethodsData from GynOp were cross‐linked with data on dispensed drugs extracted from the Swedish Prescribed Drug Register.Main outcome measuresProportion of women dispensed MHT at least once within 1 year after surgery. Repeated treatment episodes were defined, and the proportion of ‘person time’ covered by dispensations was analysed.ResultsIn total, 1231 of all women (n = 1706) were dispensed MHT at some point after surgery, with 1177 women dispensed MHT within 1 year. This proportion increased from 64% in 2005 to 84% in 2019 (p < 0.001). In the total population, 4537 ‘treatment years’ transpired, corresponding to 43% of the mean time covered. In women dispensed MHT within 1 year, the proportion of time covered was 63%.ConclusionsOnly 69% of all women without malignancy of any kind who underwent bilateral oophorectomy were dispensed MHT within 1 year after surgery, and the duration of treatment was limited. It is important to study further the reasons behind the low dispensation rate in this group to increase adherence to current treatment guidelines, improve quality of life, and avoid increased morbidity and mortality.

Published: September 2023

AbstractIf unauthorized resource use is prevented, managing marine resources by allocating property rights may match economic and environmental conservation incentives. However, because of the developing exploitation of marine resources and accompanying pollution, species' living conditions in Europe's waters are changing more quickly than before. By considering the roles of fisheries productivity, intellectual property rights, intellectual capital rights, market size, governance, and economic growth from 1990 to 2022, this paper aims to investigate the dynamic effect of property rights factors on the sustainability of the fisheries industry in 27 European countries. At higher quantiles, the findings showed a significant positive association between governance and fisheries sustainability adopting a new method, the MMQR with fixed effects, the Method of Moments Quantile Regression. In addition, in EU27 nations, the impact of intellectual property rights was favorable and statistically significant from the first to ninth quantiles. The findings show that the EU14 developed nations have more excellent governance and intellectual capital rights than the EU13 developing countries, significantly benefiting fisheries sustainability. In the same way that market size and economic growth condense fisheries sustainability in EU14 developed and EU13 developing countries, it has been discovered that intellectual property rights do the same across all quantiles, supporting the growth hypothesis for fisheries‐producing countries. The findings specifically show that the beneficial solid impact of intellectual property rights, market size, and economic development on the sustainability of fisheries is more significant in EU13 developing nations than in EU14 developed countries. These results provide policymakers with helpful information for promoting property rights aspects in EU14 and EU13 nations via effective green technologies in the fisheries sector to meet sustainable development objectives.
Delayed esophageal anastomotic complication and ramucirumab therapy: A case report
Authors: Roth Robert H. , Malfitano Madison J. , Reilley Matthew , Martin Linda W. 
Published: September 2023

AbstractCurrent NCCN guidelines for second‐line therapy in recurrent or metastatic esophago‐gastric cancers recommend the use of VEGF inhibitors such as ramucirumab. VEGF inhibitors have been shown to be associated with gastrointestinal perforation in clinical trials and late colorectal anastomotic leaks in a few case reports. Here, we present a case of late esophageal anastomotic leak in a patient receiving ramucirumab. Case information was obtained from our institution's electronic medical records. The patient was found to have T4N1M0, poorly differentiated invasive adenocarcinoma and subsequently received neoadjuvant chemoradiation followed by hybrid Ivor‐Lewis esophagectomy 6 weeks later. He recovered well with no leak or perioperative complications. The patient had disease progression 9 months postoperatively on CT and PET imaging. Sixteen months after surgery he began paclitaxel and ramucirumab and 16 weeks after ramucirumab initiation, he was found to have an esophago‐pulmonary fistula in the region of the anastomosis. Biopsies were negative for recurrence at the anastomosis. He died one week later from progressive pneumonia despite stenting. In conclusion, this is the only known report of delayed esophageal anastomotic complication associated with ramucirumab. VEGF inhibitor therapies such as bevacizumab have been associated with late (greater than 3 months postoperative) colorectal anastomotic complications including fistulas and leaks. Risk factors that have been associated are perioperative radiotherapy and history of early postoperative leak. These findings raise concern whether VEGF inhibitor therapy should be used in post‐esophagectomy patients with recurrence if these rare but catastrophic events are likely to be terminal.

AbstractBackgroundIn this study, the focus was primarily on examining the occurrence of lymph node metastasis in T1 lung adenocarcinoma, while also analyzing the relationship between clinical variables such as imaging characteristics, pathological classifications, and lymph node metastasis.MethodsWe retrospectively analyzed data from patients with T1 lung adenocarcinoma who underwent lobectomy and lymph node dissection between January 2016 and December 2019. Utilizing univariate and multivariate analyses, we assessed the associations between lymph node metastasis and various clinical factors, including imaging characteristics, lesion location and depth, and pathological subtypes.ResultsOf the 433 patients with T1 lung adenocarcinoma, 139 had lymph node metastasis. Moreover, the incidence of node 1 (N1) lymph node, sequential, and node 2 (N2) skip metastases were 12.2%, 12.7%, and 7.2%, respectively. Univariate analysis revealed that tumor diameter, depth ratio, sex, invasive imaging features, and pathological subtype were significantly associated with lymph node metastasis. Multivariate analysis revealed that the tumor depth ratio, tumor diameter, pleural indentation or traction sign, nonvascular penetration sign, solid component, nonadherence, and micropapillary pathological subtype were risk factors for lymph node metastasis. In the multivariate analysis, the micropapillary pathological subtype was an independent risk factor for N2 skip metastasis.ConclusionsIn patients with clinical stage T1 lung adenocarcinoma, the risk of lymph node metastasis is higher for tumors located deep within the lung tissue with solid components, invasive preoperative imaging features, and larger diameters. For N2 skip lymph node metastasis, the micropapillary pathological subtype represents a significant high‐risk factor.
Activation of Epac in the BLA disrupts reconsolidation and attenuates heroin‐seeking behaviour

AbstractThe susceptibility to drug cravings evoked by stimuli poses a formidable hurdle in the treatment of addiction and the prevention of relapse. Pharmacological interventions targeting drug‐associated memories hold promise for curbing relapse by impeding the process of memory reconsolidation, predominantly governed by cAMP signalling. Exchange Protein Activated by cAMP (Epac) serves as a distinctive mediator of cAMP signalling, which has been implicated in reinforcing the effects of cocaine and facilitating the acquisition. Nonetheless, the role of Epac in heroin‐related memory and the subsequent seeking behaviour remains enigmatic. In this study, we explored the impact of Epac activation on the reconsolidation process of drug‐related memories associated with heroin self‐administration. Over the course of 10 consecutive days, rats underwent training, wherein they acquired the behaviour of nose poking to obtain heroin accompanied by a tone + light cue. This nose‐poking behaviour was subsequently extinguished when heroin infusion and cue presentation were discontinued. Subsequently, we administered 8‐pCPT‐cAMP (8‐CPT), an Epac‐specific activator, into the basolateral amygdala at various time points, either in the presence or absence of a conditioned stimulus. Our findings demonstrate that administering 8‐CPT immediately after memory retrieval effectively reduces cue‐ and heroin‐induced reinstatement, with the observed effects persisting significantly for a minimum of 28 days. However, infusion of 8‐CPT for a duration of 6 h following the memory retrieval trial, or without it altogether, had no discernible impact. Thus, these findings strongly suggest that Epac activation can disrupt the reconsolidation of heroin‐associated memory, thereby diminishing the reinstatement of heroin‐seeking behaviour.
Differences in mammal communities between forest fragments and restoration areas in the Atlantic Forest
Authors: Marques Fernanda Cristina , dos Anjos Luiz 
Published: September 2023

AbstractThe persistence of larger mammals in fragmented forest landscapes depends not only on the protection of remaining habitats but also on ecological restoration sites. It is known that the landscape context is an important predictor of species persistence, abundance and distribution. Here we evaluate how landscape characteristics influence the recovery of larger mammals in ecological restoration sites. We assess the richness and composition of mammals in forest fragments and restoration sites using landscape metrics such as forest cover and connectivity. Forest fragments and restoration sites present the same richness (n = 26), but differ in species composition. Some seed‐dispersing mammals were absent in restoration areas, such as Alouatta guariba (brown howler monkey) and Coendou spinosus (paraguayan hairy dwarf porcupine). The percentage of forest cover in the landscape was responsible for 29.09% of the variation in species composition between the evaluated forest formations, exerting a positive or negative influence depending on the species requirements. The results demonstrate the importance of considering not only landscape metrics in an ecological restoration plan, but also the historical landscape context, such as the fauna composition before the disturbance and how these species respond to environmental changes, thus improving the success of future ecological restoration measurements and policies.

AbstractDung beetles feed mainly on scarce and ephemeral mammalian faeces making them vulnerable to declines of mammal populations. Therefore, studying how diverse groups like the Scarabaeinae subfamily utilize alternative food sources, such as decomposing invertebrates, enhances our understanding of their distribution and resilience in defaunated areas. One poorly studied aspect of the feeding habits of dung beetles is the potential differences between the sexes and their predatory behaviour. We evaluated how the sex (male and female) of individuals of Chalconotus convexus affected individual resource attraction to different bait types. Since C. convexus is known to feed on faeces, carrion and dead millipedes, we also test whether it can predate live individuals of millipedes. We used a combination of two field samplings and one laboratory experiment, using pitfall traps baited with faeces, carrion, millipedes and millipede's defensive compounds. While the preference for millipede was not associated with sex, we found a significant relationship between faeces and carrion, where females of C. convexus are significantly less attracted to faeces when compared to males and also males are significantly less attracted to carrion when compared to females. Furthermore, we also show that while actively consuming dead millipedes, C. convexus is unable to predate on live individuals. Our study illustrates that the versatility of food sources may help to explain the high abundance and wide distribution of C. convexus in Africa.
