12 December 2024Adsorption of Bisphenol A and 2,6-Dichlorophenol in Water Using Magnetic Phosphogypsum Composite Materials
Phenolic pollutants in water bodies pose a huge threat to human health and environmental safety. In this paper, a hydrophobicity-enhanced magnetic C-SiO2/MPG composite was prepared by a two-step method to remove bisphenol A (BPA)and 2,6-dichlorophenol (2,6-DCP), typical phenolic trace pollutants in livestock wastewater and natural water bodies. The results of pH gradient experiments showed that C-SiO2/MPG showed a stable removal effect on BPA in the pH range of 2–11. The adsorption of 2,6-DCP by C-SiO2/MPG peaked at pH = 2, while the adsorption of 2,6-DCP by C-SiO2/MPG was severely inhibited under alkaline conditions. The PSO kinetic model and the Langmuir isotherm model can better describe the adsorption process of BPA and 2,6-DCP on C-SiO2/MPG, indicating that the monolayer chemical adsorption has a rate-controlling step. With the Langmuir equation fitting, the maximum adsorption capacity of C-SiO2/MPG for BPA and 2,6-DCP at 298 K was calculated to be 561.79 mg/g and 531.91 mg/g, respectively. The results of adsorption thermodynamics indicated that the adsorption of BPA and 2,6-DCP on C-SiO2/MPG was spontaneous, accompanied by a process of entropy decrease. C-SiO2/MPG showed good environmental resistance and repeated use stability for BPA and 2,6-DCP in electrolyte ion interference, actual water samples and cycle experiments. Mechanism analysis showed that the adsorption of BPA and 2,6-DCP on C-SiO2/MPG was mainly controlled by hydrogen bonding and hydrophobic interactions. This study designed an efficient adsorbent for phenolic pollutants that can be used in actual wastewater and broadened the resource utilization of industrial waste phosphogypsm.

09 December 2024Synthesize and Applications of Biodegradable Plastics as a Solution for Environmental Pollution Due to Non-Biodegradable Plastics, a Review
Biodegradable plastics are a potential sustainable alternative to conventional petrochemical-based non-degradable plastics. Due to their lightweight, flexibility, durability, versatile applications, chemical inertness, electrical and heat insulation, and conductivity, plastics have become an essential material for many industries, with annual production currently exceeding 450 million tons. However, these materials are non-biodegradable, leading to detrimental consequences such as the formation of microplastics from improper disposal and the generation of toxic gases, including furans, dioxins, mercury, and polychlorinated biphenyls, from burning plastic waste. This results in environmental pollution, affecting land, water bodies, and the atmosphere. In response, studies where the focus has been on creating bio-degradable polymers such as polylactic acid, polyhydroxy alkanoates, Polycaprolactone, Poly(butylene adipate-co-terephthalate), and Polybutylene succinate, which were extracted from renewable resources or chemically modified as biodegradable polymers. Biodegradable polymers exhibit a wide range of properties and can now be modified to be used in various applications suitable for substituting some conventional plastic products. Thus, the article highlights the critical issue of environmental pollution caused by non-biodegradable plastics and provides a comprehensive overview of the synthesis processes, properties, novel applications, and challenges associated with the use of biodegradable plastics.

09 December 2024The Multifaceted Roles of Neutrophil Death in COPD and Lung Cancer
Chronic obstructive pulmonary disease (COPD) and lung cancer are closely linked, with individuals suffering from COPD at a significantly higher risk of developing lung cancer. The mechanisms driving this increased risk are multifaceted, involving genomic instability, immune dysregulation, and alterations in the lung environment. Neutrophils, the most abundant myeloid cells in human blood, have emerged as critical regulators of inflammation in both COPD and lung cancer. Despite their short lifespan, neutrophils contribute to disease progression through various forms of programmed cell death, including apoptosis, necroptosis, ferroptosis, pyroptosis, and NETosis, a form of neutrophil death with neutrophil extracellular traps (NETs) formation. These distinct death pathways affect inflammatory responses, tissue remodeling, and disease progression in COPD and lung cancer. This review provides an in-depth exploration of the mechanisms regulating neutrophil death, the interplay between various cell death pathways, and their influence on disease progression. Additionally, we highlight emerging therapeutic approaches aimed at targeting neutrophil death pathways, presenting promising new interventions to enhance treatment outcomes in COPD and lung cancer.

06 December 2024Population Dynamics and Stock Assessment of the Spottail Mantis Shrimp Squilla mantis (Linnaeus, 1758) in the North Aegean Sea, Greece
In Greek waters, the spottail mantis shrimp Squilla mantis (Linnaeus, 1758) presents significant ecological and low to moderate economic value. This study investigates the population dynamics and stock assessment of the species in the north Aegean Sea. A total of 856 individuals were collected using commercial bottom trawls between April 2021 and April 2023. Key population parameters such as size distribution, sex ratio, growth, size at maturity and spawning seasonality were assessed. Results indicate a relatively stable population with a slight male dominance and peak spawning activity occurring in late spring to early summer. Growth parameters were estimated using the von Bertalanffy growth model, revealing moderate growth rates and a maximum length slightly higher than previously recorded for this species in other Mediterranean regions. Stock assessment, conducted through yield-per-recruit analysis, suggests that the current exploitation levels are approaching sustainable limits. However, potential overfishing risks necessitate continuous monitoring and the implementation of adaptive management strategies. This study underscores the importance of integrative approaches combining biological and fisheries data to ensure the sustainable management of S. mantis populations in the Aegean Sea.

05 December 2024Improving Postmortem Dental Profiling: The Integration of Intraoral Scanners in Dental Autopsies
Forensic odontology plays a crucial role in human identification, particularly in cases where traditional identification methods face challenges such as severe trauma, decomposition, skeletonization, or carbonization. The evolution of digital dentistry has significantly advanced dental autopsies, particularly through the use of intraoral scanners (IOSs). These devices provide a non-invasive and efficient method for capturing detailed impressions of dentition and photographic images of teeth. The benefits of intraoral scanning in analyzing human remains in forensic odontology are endless. Digital impressions can be easily stored, shared, and transmitted electronically, eliminating the need for physical storage or transportation of dental models. This technology also enables remote postmortem dental profiling. By combining digital models with antemortem dental records, forensic odontologists can more efficiently identify matches and discrepancies, with the added benefit of future advancements in artificial intelligence(AI). Intraoral scanning should be considered a routine process in all dental autopsies to improve postmortem dental data collection and archive. Forensic odontologists should be equipped with a portable X-ray device, a digital sensor, and an IOS.

03 December 2024Pathway Engineering of E. coli for Production of Fritschiellaxanthin and Other Carotenoids with α-Carotene Backbone and Their Singlet Oxygen-Quenching Activities
Some photosynthetic organisms are capable of biosynthesizing carotenoids (xanthophylls) with α-carotene backbone, that is, α-carotene-derived carotenoids, such as (3R,3′R,6′R)-3,3′-dihydroxy α-carotene (lutein). Except for lutein, such carotenoids are minor compounds in nature. In this study, α-carotene-derived carotenoids were produced with E. coli. To achieve this, carotenoid biosynthesis genes from the bacterium Pantoea ananatis containing the 4-β-ketolase (crtW) gene with/without the 3-β-hydroxylase (crtZ) gene, in addition to crtEBI genes, and biosynthesis genes (MpLCYb, MpLCYe, and MpCYP97C) from liverwort Marchantia polymorpha, along with the HpIDI gene, were cloned into plasmids. The transformed E. coli cells biosynthesized (3S,3′R,6′R)-3,3′-dihydroxy-4-keto-α-carotene (fritschiellaxanthin (4-ketolutein)), (3′R,6′R)-3′-hydroxy-4-keto-α-carotene (4-keto-α-cryptoxanthin), and (3′R,6′R)-3′-hydroxy-α-carotene (α-cryptoxanthin), as carotenoids that have not been produced by a heterologous microbial system so far. These carotenoids show potent singlet oxygen-quenching activity.
