Summary: This study evaluated four different chemical disinfectants for their potential use in inland fish farms to control red tides. It found that ozone (O3) and permanganate (MnO4 ) showed the highest efficacy in inactivating C. polykrikoides cells. Sodium hypochlorite (NaOCl) and hydrogen peroxide (H2O2) also showed effectiveness but produced byproducts and had lower toxicity to fish. Based on the overall factors, H2O2 was suggested as the most practical disinfectant for controlling red tides in inland fish farms.

Summary: This study analyzed the DNA content of 141 Salvia genotypes using flow cytometry. The results showed a wide distribution of DNA content across chromosome number, ploidy, and Glade in Salvia. This further demonstrates the diversity of Salvia and may be beneficial for future breeding efforts.

Summary: The research found that typhoons have a significant influence on the bloom and termination of the harmful alga Cochlodinium polykrikoides, particularly in terms of wind direction and wave energy. The level of wave energy plays a critical role in terminating the blooms of C. polykrikoides during typhoons.

Summary: The novel MCA gene PmMCA was cloned from the harmful dinoflagellate Prorocentrum minimum, and its expression and cell apoptosis were significantly induced under copper exposure, affecting cell growth. These findings suggest that PmMCA may be involved in PCD triggered by copper stress.

Summary: This study investigated the effect of high temperature conditions on the diel vertical migration (DVM) of the harmful dinoflagellate Cochlodinium polykrikoides, which causes mass mortality of farmed fish. The field and laboratory results indicate that C. polykrikoides uses thermotaxic DVM as an important ecological strategy to optimize environmental conditions for growth through vertical positioning and changing migration velocity.

Summary: During the summer monsoon, the Changjiang River discharge enters the Korean coastal waters, resulting in Changjiang diluted water. The harmful dinoflagellate Cochlodinium polykrikoides causes massive blooms during this period, leading to economic losses. This study suggests that the intrusion strength of Changjiang diluted water plays a crucial role in regulating the scale of Cochlodinium polykrikoides blooms.

Summary: Orchidaceae is one of the largest and most widespread plant families, with genome size estimation by flow cytometry revealing that the investigated orchid species possess intermediate, large, and very large genomes. The study estimated the genome sizes of 15 orchid species and one infraspecific taxon growing wild in Poland, providing additional criterion for orchid species identification and characterization.

Summary: A reliable protocol has been developed to label both functional and non-functional brain pericytes, allowing for the evaluation of their contractility and structure using high-resolution confocal microscopy. Investigating the contractility of brain pericytes in the context of SAH provides insights into its impact on cerebral microcirculation.

Summary: The study found that in 2018, high water temperatures and heatwaves in Korean coastal waters led to the bloom of harmful dinoflagellate Cochlodinium polykrikoides. Early stratification conditions played a critical role in the algae bloom, but maintaining the bloom under high water temperatures had a negative impact.

Summary: A modified NPZD ecosystem model is used to investigate the effects of predation avoidance on harmful algal blooms (HABs). The addition of a phytoplankton group with slower nutrient uptake and better predation avoidance characteristics in the model helps resolve HAB development caused by predation avoidance. The presence of zooplankton is necessary for the system to reach equilibrium, where only the non-harmful phytoplankton group can survive against the HAB group in resource competition. The model's analytical results contribute to HAB modeling strategies and guide the determination of model coefficients for resolving HAB events.

Summary: Food processing, such as freeze-drying, can reduce the viability and activity of bacteria in food. We developed a staining-based flow cytometry method to accurately detect the viability/activity of Lacticaseibacillus (Lb.) casei Zhang, a commonly used probiotic. This method showed comparable results to standard plate counts and was also able to detect viable but unculturable cells in freeze-dried samples.

Summary: This study presents a label-free impedance-based approach for cell viability assessment by characterizing multiple electrical cellular phenotypes in a high-throughput manner, introducing a concept called the complex opacity spectrum for improved discrimination of live and dead cells. The approach successfully discriminated between living and dead cells in different experimental scenarios and provides highly accurate and consistent cell viability analysis, validated by commercial fluorescence-based flow cytometry.

Summary: This study measured the genome size of Gryllotalpa orientalis and identified nuclear repetitive elements. The estimated haploid genome size was 3.14 Gb by flow cytometry and ranged from 3.17 Gb to 3.77 Gb based on two k-mer methods. Class I-LINE retrotransposon elements were the most common families among the annotated repetitive elements.

Summary: Genome size variation and hybridization in plants are influenced by altitude. This study found a strong correlation between altitude and genome size in Elymus species, and larger genome size variations occurred in mid-altitude populations compared to other altitudes.

Summary: Exposure to an electron beam at <= 1 kGy dose leads to inactivation of more than 4/5 of the population of Cochlodinium polykrikoides and Alexandrium catenella toxic microalgae via damage to cell walls, degradation of chloroplasts, and cell aggregation. The neutralization of paralytic toxins also occurs. Due to the low doses, efficiency, and simplicity of irradiation, electron beam treatment can be a promising method of controlling red tides in seawater.
