Summary: The study found that in oysters from an urban estuary in Northeast Brazil, the bioaccumulation of Hg was higher during the rainy season, and changes in biomarkers indicated elevated stresses for organisms in the inner portion of the estuary. However, no correlation was observed between Hg in sediment/oyster and biomarker results.

Summary: Various microbial infections contribute to coral disease progression and mortality. The holobiont and external surfaces of coral create a diverse microenvironment that attracts ciliates based on their feeding preferences. Ciliates can enter corals through injuries or interact indirectly with other microbes, affecting coral health. Ciliates are associated with 12 different diseases globally, with diverse ciliate associations observed in white syndrome disease lesions and diseased Acropora genera. Some ciliate species ingest coral Symbiodiniaceae and histophagous ciliates as secondary invaders, leading to tissue loss. However, the nature of ciliate association with coral disease remains unclear.

Summary: The toxic effects of nitrofurazone (NFZ) on protozoans can serve as an early warning signal of NFZ contamination in aquatic environments. This study found significant differences in species composition and toxic dynamics patterns among different concentrations of NFZ. The results also suggest that protozoan periphytons can be used as bioindicators to assess the ecotoxicity of NFZ in the marine environment.

Summary: This study investigated the disparity of responses shown by body-size spectra of periphytic ciliate communities when used as biomarkers to detect the toxicity of the broad-spectrum veterinary antibiotic nitrofurazone. The results demonstrated that body-size spectra and body-size distinctness offered clear evidence of nitrofurazone toxicity in periphytic ciliates. Therefore, body-size spectra can be used as a pivotal biomarker to determine the ecotoxicity of nitrofurazone in aquatic environments.

Summary: The study identified proteins associated with Ichthyophthirius multifiliis in the skin mucus of common carp, revealing their roles in motility, virulence, and stress response during parasite growth. These proteins may affect host immune responses and wound healing, providing insights into the invasion strategy of the parasite.

Summary: This study investigated the importance of impaired ciliary length and aberrant DNAI1 localization as pathological characteristics in nasal mucosa of patients with allergic rhinitis (AR). The results showed that patients with AR had significantly reduced ciliary length and higher DNAI1 scores compared to controls. These findings suggest that shorter ciliary length and aberrant DNAI1 localization may be important pathological features of allergic nasal mucosa.

Summary: The present research aims to evaluate the variation of several responses in marine mussels exposed to different sub-lethal concentrations of copper and lead. The results showed that temperature and salinity variations were not significant enough to interfere with the effect of the pollutants. Changes in nitrogen and phosphorus mineral matter were found to be a physiological disturbance in both species. During the contamination cycles, catalase induction and protein depletion reflected the oxidative stress caused by the metals. However, the catalase activity returned to normal state during the decontamination cycles.

Summary: This study investigated the influence of a negatively charged benzene ring containing surfactant, sodium dodecylbenzene sulphonate (SDBS), on the fibrillation of bovine liver catalase (BLC). It was found that lower concentrations of SDBS promoted the native-like alpha-helical structure of BLC, while higher concentrations led to aggregation and the formation of amyloid-like structures. At pH 2.0, higher concentrations of SDBS enabled BLC to regain its native-like alpha-helical structure.

Summary: Reactive oxygen species play a crucial role in regulating plant responses to environmental stress, with hydrogen peroxide levels increasing under prolonged iron deficiency to inhibit Fe acquisition through the regulation of FIT. CAT2 and FIT are involved in a regulatory loop between H2O2 and prolonged Fe deficiency, influencing downstream regulators in the Fe homeostasis transcription cascade.

Summary: The terrestrial ciliated protozoan Colpoda cucullus can transform into resting cysts in response to unfavorable habitat conditions. The induction of cyst formation is triggered by a rapid increase in temperature, rather than a decrease, and requires an increase in intracellular Ca2+ concentrations. The release of Ca2+ from vesicles activates multiple signaling pathways, with cAMP potentially serving as a crucial second messenger in the process of temperature-induced encystment.

Summary: Through the study of the cat2 mutant in Arabidopsis, which lacks the major leaf isoform of catalase, we are able to investigate the potential impact of intracellular H2O2 on plant function. Our analysis focused on the salicylic acid and jasmonic acid pathways reveals metabolic signatures associated with oxidative stress-induced signaling via these defense hormones. We also identify specific enzymes and genes involved in the glucosylation of SA and the production of dihydroxybenzoic acid glycosides.

Summary: Morphogenesis is a crucial process that occurs in organisms like ciliated protists. This process is particularly complex during conjugation in ciliates. The study on morphogenesis during conjugation in Euplotes raikovi Agamaliev, 1966 showed reorganization of ciliature, generation of adoral zone of membranelles, formation of frontoventral-transverse cirri anlagen, and the stability of dorsal ciliature.

Summary: Analysis of 273 ancient horse genomes reveals that modern domestic horses originated in the Western Eurasian steppes, especially the lower Volga-Don region. The domestication of horses led to the rapid expansion of modern domestic horses across Eurasia around 2000 bc, replacing almost all other local populations.

Summary: This study investigates the electrical signaling mechanism in Venus flytraps and discovers that trigger hairs can turn mechanical stimuli into calcium signals and action potentials, which then propagate through ion channels and pumps within the plant. The propagation of electrical signals is suppressed by anesthesia but does not affect the initiation of calcium signals by touch stimulation. This research is important for understanding the electrical signaling in plants.

Phylogenetic analysis revealed that they belong to three monophyletic suctorian orders, with the family Heliophryidae now being transferred from Evaginogenida to Endogenida based on evidence of endogenous budding reproduction by the type genus Heliophrya.

Summary: Research found that tobacco leaves exhibit significant leaf movements and detoxify sodium ions through the release of cellular water under salt stress. Tobacco leaves can recover quickly after salt stress, and this recovery process depends on plasma membrane hydrogen ion pumps and vacuolar ion exchange. Unlike roots, salt stress signaling and processing in tobacco leaves do not rely on calcium signaling.
