Biodegradable Foam (Biofoam) material has been made for application of styrofoam substitute food packaging material from a mixture of starch with chitosan as an additive. The purpose of this study was to determine the effect of molding temperature on biofoam products and to determine the effect of chitosan addition on the physical, mechanical, and biodegrability properties of biofoam made from cassava peel starch (a) and banana peel starch (b) which is close to commercial biofoam standards. The production of biofoam uses variations in molding temperature of 125, 150 and 175 °C and variations in chitosan weight with variations of 0, 1, 2 and 3 grams. The resulting biofoam product was then tested for density, water absorption, compressive strength, biodegradation and functional groups with Fourier Transform Infrared (FTIR). Based on the results of the study, it is known that biofoam that is close to commercial standards is found in the addition of 3 gr chitosan weight with a molding temperature of 125 °C with a density value of 0.423gr/cm3, water absorption of 42.54% and compressive strength of 0.0045 Mpa. As for biodegradation, biofoam products will decompose 55.17% for 55 days in 0 g chitosan weight with a thermopressing temperature of 175 °C. The spectrum results obtained on biofoam have C-H, C-O, C-N, N-H, C=O and O-H functional groups.

Published: June 2024

AbstractDue to the spread of the communicative language teaching method language learners were often encouraged not to use a dictionary but rather infer the meaning of a word or phrase from its context. Proper dictionary use, however, is now seen as an important element of autonomous and life-long language learning. The present research used the quantitative research paradigm and a self-prepared questionnaire (n = 925) to investigate attitudes towards dictionary use in the case of university students studying languages for business. The study investigated participants' willingness to use and pay for dictionaries and their willingness to read usage guides in dictionaries. Our results show that participants typically use a dictionary if they do not know the meaning of a word or phrase, but are reluctant to buy a dictionary and are likewise unwilling to read the information guides in dictionaries. Our results also reveal that willingness to pay for dictionaries is positively influenced by willingness to use dictionaries, willingness to read usage guides in dictionaries and language learners' age.

Published: June 2024

Patient-specific cardiovascular simulation is emerging as a potent tool for basic, translational, and clinical research and has established itself as a paradigm in the field of cardiovascular science. The SimVascular software package, considered a state-of-the-art open-source package, offers a comprehensive pipeline from medical imaging data segmentation to patient-specific blood flow simulation and analysis. In this study, we employ SimVascular to explore a model of coronary arteries in a young and healthy 24-year-old woman. The outcomes of the entire simulation process encompass the assessment of flow and pressure waveforms at both the outlet of the aorta and the coronary arteries, which serve as indicators of blood flow qualities within these vessels. Given the pivotal role of wall shear stress in the development of arterial plaque, SimVascular employs the finite element method to solve the governing equations of incompressible viscous fluids. This approach effectively tackles the Navier-Stokes equations along the vessel wall using meticulously constructed mesh components. Additionally, this paper delves into the issue of cardiovascular blood vessel dynamics via an analysis of wall shear stress data).

The reservoir water level fluctuation zones (RWLFZs) and the natural riparian zones (NRZs) are two riparian ecosystems with the dramatically opposite hydrological rhythms which notably influence the plant guilds. However, little is known about the discrepancy of functional traits and niche characteristics of plant guilds in the RWLFZ and NRZ under different flooding rhythms. Here the RWLFZs (degraded riparian zones) and NRZs were chosen in the Xiangxi River Basin of the Three Gorges Reservoir (TGR) to investigate the variation in plant community structure, the spatial patterns of diversity, key functional traits and niche characteristics of dominant plant populations. The results showed that a total of 78 vascular plant species were identified in the riparian zones of Xiangxi River Basin. Most of the dominant species were annual herbs in the two riparian ecosystems and the percentage of annual dominant species increased from 65.79% in the NRZ to 67.34% in the RWLFZ. Compared with the NRZ, the specific leaf area, vegetation coverage and the aboveground biomass in the RWLFZ significantly increased by 74%, 27% and 19.6% respectively, while the water use efficiency of the RWLFZ decreased by 59.6% and there was no significant difference in the net photosynthetic rate between them, which showed that annuals in the RWLFZ adopt the R adaptation strategy with fast-growing, short lifespan and quickly acquiring and investing resources by altering leaf morphology such as expanding leaf area. The Simpson dominance index of RWLFZ was significantly higher than that of NRZ. Thus counter-seasonally hydrological alterations had the significant effects on functional traits of dominant species in the RWFLZ. Moreover, the highly adaptable and widely distributed species with larger niche breadths and high important values usually had a higher niche overlap value in the RWLFZ than in the NRZ, which showed that the competition in the plant community after experiencing anti-seasonal flooding was much more intraspecific than interspecific and would facilitate the expansion of species niches. And the distribution of the plant community was mainly driven by elevation (flooding depth), flooding duration and TK in the WLFZs. Our findings imply that the species with large niche breadths and high important values should be prioritized in ecological restoration efforts in the newly formed hydro-fluctuation zone of the TGR.

Published: June 2024

Abstract

Conducting polymers are of great interest in bioimaging, bio-interfaces, and bioelectronics for their biocompatibility and the unique combination of optical, electrical, and mechanical properties. They are typically prepared outside through traditional organic synthesis and delivered into the biological systems. The ability to call for the polymerization ingredients available inside the living systems to generate conducting polymers in vivo will offer new venues in future biomedical applications. This study is the first report of in vivo synthesis of an n-doped conducting polymer (n-PBDF) within live zebrafish embryos, achieved through whole blood catalyzed polymerization of 3,7-dihydrobenzo[1,2-b:4,5-b′]difuran-2,6-dione (BDF). Prior to this, the efficacy of such a polymerization was rigorously established through a sequence of in vitro experiments involving Hemin, Hemoproteins (Hemoglobin, Myoglobin, and Cytochrome C), red blood cells, and the whole blood. Ultimately, in cellulo formed n-PBDF within cultured primary neurons demonstrated enhanced bio-interfaces and led to effective light-induced neural activation—a capability not observed with the pre-fabricated polymer. This underscores the potential advantages of synthesizing conducting polymers directly in living systems for biomedical applications.
Randomized Controlled Trial of Enteral Vitamin D Supplementation (ViDES) in Infants &lt;28 Weeks Gestational Age or &lt;1000 Grams Birth Weight: Study Protocol
Authors: Romero-Lopez Mar , Tyson Jon E , Naik Mamta , Pedroza Claudia , Holzapfel Lindsay F , Avritscher Elenir , Mosquera Ricardo , Khan Amir , Rysavy Matthew 
Published: June 2024

Abstract

Background
Vitamin D is necessary to develop healthy lungs and other organs early in life. Most infants born before 28 weeks’ gestation have low vitamin D levels at birth and a limited intake during the first month. Enteral vitamin D supplementation is inexpensive and widely used. The appropriate supplementation regimen for extremely preterm infants is controversial, and the effect of different regimens on their blood levels and outcomes is unclear.
Methods
Randomized, blinded comparative effectiveness trial to compare two vitamin D supplementation regimens for inborn infants <28 weeks gestation or <1000 grams birth weight at a large academic center in the United States.
Infants are stratified by birth weight and randomized within 96 hours after birth to either routine supplementation (400 IU/day with established feedings) or increased supplementation (800 IU/day with any feedings) during the first 28 days after birth.
We hypothesize that the higher and early vitamin D dose (800 IU/d with early feeding) compared to placebo plus routine dose (400 IU/d with established feeding) will substantially increase total 25-hydroxyvitamin D3 levels measured as state-of-art at one month, reduce respiratory support at 36 weeks’ postmenstrual age (on an ordinal scale predictive of later adverse outcomes) and improve or at least not worsen other important secondary outcomes. The infants in the study will follow up at 22-26 months’ corrected age (~2 years) with blinded certified examiners to evaluate neurodevelopmental outcomes.
The sample size of a minimum of 180 infants provides >90% power to detect a >95% posterior probability of a 33% increase in serum 25-hydroxy vitamin D3 and >80% power to detect a >80% posterior probability of a relative risk decrease of 20% of reducing respiratory support by intention-to-treat Bayesian analyses using a neutral prior probability.
Discussion
Our study will help clarify the uncertain relationship of vitamin D supplementation and its associated serum metabolites to clinical outcomes of extremely preterminfants. Confirmation of our hypotheses would prompt reconsideration of the supplementation regimens used in extremely preterm infants and justify a large multicenter study to verify the generalizability of the results.

Assessing the impact of climate change on solar energy production in Italy
Authors: Bonanno Riccardo , Collino Elena 
Published: June 2024

Abstract

This study assesses climate change's impact on solar energy production in Italy until 2100, focusing on solar radiation, temperature, and photovoltaic (PV) energy production through capacity factor. Regional climate models (RCMs) from Euro-CORDEX, which incorporate time-evolving aerosols, are utilized for accurate future solar radiation trend estimations under various Representative Concentration Pathway (RCP) scenarios. Bias correction, employing SARAH-3 for solar radiation and MERIDA reanalysis for temperature data, enhances the capacity factor accuracy.
Solar radiation exhibits a slight decline under RCP 2.6 but a significant increase under other RCPs, particularly in central Italy's mountains, with the Alps showing an opposite trend, especially under RCP 8.5. The temperature is projected to rise, particularly under RCP 4.5 and RCP 8.5, potentially affecting production efficiency and snow cover in the Alps. The decrease in snow cover may affect the diffuse component of solar radiation with a subsequent decrease predicted by Euro CORDEX RCMs.
Trend analysis reveals significant PV production decreases under RCP 8.5, especially in the Alps, due to reduced solar radiation. Despite the increase in solar radiation, most of Italy experiences decreased PV production due to rising temperatures, potentially reducing solar panel efficiency. RCP 4.5 and RCP 2.6 scenarios exhibit less pronounced capacity factor decreases, with RCP 2.6 showing the lowest climate signal magnitude.
Seasonal cycle analysis reveals variations primarily linked to changes in solar radiation throughout the year. RCP 8.5 shows significant winter production decreases, followed by slight summer increases dampened by rising temperatures. RCP 4.5 exhibits similar characteristics, with a milder winter decrease and stable production in other months, while RCP 2.6 shows a slight spring increase and generally stable production throughout the year.

Published: June 2024

Abstract

Objectives: This study aims to identify the risk factors for postoperative pulmonary complications (PPCs) in elderly patients undergoing major abdominal surgery and to investigate the relationship between patient-controlled analgesia (PCA) and PPCs.
Design: A retrospective study.
Method:Clinical data and demographic information of elderly patients (aged ≥60 years) who underwent upper abdominal surgery at the First Affiliated Hospital of Sun Yat-sen University from 2017 to 2019 were retrospectively collected. Patients with PPCs were identified using the Melbourne Group Scale Version 2 scoring system. Univariate and multivariable logistic regression analyses were conducted to identify independent risk factors for PPCs. Propensity score matching was utilized to compare PPC rates between patients with and without PCA, as well as between intravenous PCA (PCIA) and epidural PCA (PCEA) groups.
Results:A total of 1,467 patients were included, with a PPC rate of 8.7%. Multivariable analysis revealed that PCA was an independent protective factor for PPCs in elderly patients undergoing major abdominal surgery (odds ratio = 0.182, 95% confidence interval = 0.103～0.322; P < 0.001). After matching, patients receiving PCA demonstrated a significantly lower overall incidence of PPCs (8.3% vs. 24.7%, P < 0.001), unplanned transfer to the intensive care unit (1.8% vs. 8.2%, P = 0.008), and in-hospital mortality (0.4% vs. 4.1%, P = 0.024) compared to those not receiving PCA. No significant difference in outcomes was observed between patients receiving PCIA or PCEA after matching.
Conclusion:Patient-controlled analgesia, whether administered intravenously or epidurally, is associated with a reduced risk of PPCs in elderly patients undergoing major upper abdominal surgery.
