Summary: The study found that changes in the abundance of different symbiont genera within coral hosts can affect the gene expression of symbionts, particularly impacting expression of photosynthesis components and proteins related to cell movement. When both genera are represented in comparable proportions within the host, the mixed symbiosis state may lead to more intense competition but does not result in increased stress for the host. After heat treatment, corals with mixed symbiosis showed the lowest stress signatures compared to corals dominated by either Cladocopium or Durusdinium.

Summary: A study has found that taurine can significantly promote the growth and photosynthesis efficiency of Symbiodinium sp., as well as positively affect its biomass and major metabolites. Taurine may also influence the metabolic pathways and transcription processes of Symbiodinium sp. through various mechanisms, while controlling the population density and initiating a series of response mechanisms.

Summary: Most lineages of reef-building corals are highly stable for their photosymbiosis trait, with almost no instances of loss, but in some clades this trait is more labile. This provides a framework for further studies on the factors shaping the evolutionary fate of photosymbiosis in reef-building corals.

Summary: In this study, the mechanism of endosymbiosis between coral and dinoflagellates was characterized using RNAi and single-cell RNA-seq. The researchers identified a host endosymbiotic cell marker called LePin, which binds to algae to initiate phagocytosis and modulate coral immune response. The evolutionary conservation of LePin among marine anthozoans suggests its general role in coral-algal recognition.

Summary: Mutualistic relationships between reef-building corals and photosynthetic algae are crucial for supporting marine biodiversity. Specific gene expression changes, including duplications, in Acropora corals occur when they acquire native symbionts, indicating the importance of genomic novelties in coral-algae symbiosis.

Summary: Loss of foundation reef-corals is damaging reef communities globally, leading to a decline in ecosystem function. Active intervention and effective coral restoration techniques are needed to enhance coral recruitment and density. Enhancing larval supply significantly increases settlement on reefs, facilitating rapid re-establishment of breeding coral populations and enhancing fish abundance.

Summary: Experimental evolution of coral microalgal symbionts can enhance the thermotolerance of adult corals without trade-off against growth under ambient temperature. This study demonstrates that heat-evolved symbionts can persist in corals for a long time and potentially provide long-term benefits to coral thermotolerance.

Summary: Metabolic activity is crucial for understanding life on earth, and measuring organismal metabolic rates is essential for explaining physiological states, ecological roles, and the impact of environmental change on species. However, there is a lack of methods and data regarding metabolic rate measurements in coral offspring. To address this gap, this study aimed to develop a custom setup for measuring the respiration of small marine animal ecologies, allowing for improved measurement of metabolic rate.

Summary: Research found that Acropora corals tend to select a single species of symbiont, Symbiodinium microadriaticum, in early life stages, even though this species is rarely found in mature colonies. When coral larvae were exposed to native symbionts, the gene expression gradually changed, with upregulation of pattern recognition receptor-like and transporter genes, and suppression of cellular function genes related to immunity and apoptosis.

Summary: This review paper comprehensively discusses the management and research aspects of e-waste in an Asian developing country. The lack of effective management and recycling systems in Vietnam has resulted in localized contamination and human exposure to toxic chemicals. Primitive processing activities have been identified as significant contributors to environmental emissions and human exposure to toxic elements and pollutants. Informal e-waste processing releases pollutants at similar levels as large-scale facilities in developed countries.

Summary: The co-occurrence of halogenated flame retardants (HFRs) and organophosphate esters (OPEs) in the environment of informal waste processing areas in Vietnam was investigated in this study. The results showed higher levels of HFRs and OPEs in the e-waste recycling workshops compared to the vehicle processing workshops, suggesting different usage patterns of these substances in different industries. The human health risk related to HFRs and OPEs in settled dust was found to be low.

Summary: This study aimed to investigate the relationship between antithrombin (AT) activity levels and long-term outcomes in patients with traumatic brain injury (TBI). The study found that low AT activity levels within 1 hour after injury were associated with poor outcomes, and AT activity levels 1 hour after injury had a strong predictive value for long-term outcomes.

Summary: Coagulopathy is a common complication of traumatic brain injury, characterized by immediate hypercoagulability followed by hyperfibrinolysis and bleeding. Monitoring coagulation and fibrinolysis parameters is crucial for treatment strategies, and D-dimer and consciousness levels can predict patient prognosis. Avoiding surgery during the peak of fibrinolysis and bleeding diathesis, around 3 hours after injury, is recommended.

Summary: In this study, the risk of endocrine disruption caused by polycyclic aromatic compounds, particularly oxygenated and nitrated polycyclic aromatic hydrocarbons (oxy-PAHs and nitro-PAHs), was investigated. The antiandrogenic and estrogenic activities of 27 compounds, including oxy-PAHs and nitro-PAHs, were determined using CALUX assays. The results showed that certain oxy-PAHs exhibited potent inhibition of AR activation, while all nitro-PAHs showed high antiandrogenic activities. Two oxy-PAHs demonstrated prominent estrogenic activity. Understanding the effects of polycyclic aromatic compounds on endocrine dysfunctions in mammals and aquatic organisms, mediated by AR and ER, remains a challenge.

Summary: In this study, the lipid contents of eggs and sperm of Acropora tenuis were analyzed, and the amount of each lipid class and fatty acid levels were calculated. The composition of the major phospholipid, phosphatidylcholine (PC), was investigated, and mass spectrometry imaging was performed to visualize molecular distribution in a bundle. It was found that the PC compositions of eggs and sperm were completely different, and n-3 fatty acids were enriched in the sperm, with eicosapentaenoic acid-conjugated PCs predominantly localized as a bundle in the sperm. This approach shows promise for analyzing bundle conditions.

Summary: The S-29 haplotype in Brassica rapa does not require MLPK function for self-incompatibility, unlike other S haplotypes. MLPK is known to be essential for SI in Brassica rapa and Brassica napus, but not in Arabidopsis thaliana. This study provides insights into the relationship between S-haplotype diversity and MLPK function in Brassicaceae.

Summary: The growth of environmental stress cracks is responsible for the fragmentation of degraded plastics and release of smaller secondary microplastics. Chemical degradation can be used to analyze crack patterns and provide valuable information on microplastic generation. This study examined cross-sections of plastic fragments collected from two beaches in Japan and found that the depth of crack growth varied among different types of plastics, suggesting the release of different types of microplastics. The behavior of plastic degradation in the depth direction is dependent on the type of plastic.
