Taxonomy, geographic distribution and molecular phylogeny of two freshwater Frontonia (Ciliophora, Peniculida), including a new cryptic species Frontonia paraleucas sp. nov.

The ciliate genus Frontonia, one of the most species-rich groups of the order Peniculida, is widely distributed across a variety of habitats. However, the definition and identification of isolates are challenging, as there are few reliable characters, and these may overlap among congeners. In the present study, we describe two easily confused species, including a new form F.

Biomonitoring and bioremediating potential of commonly grown tree species against trace elements with seasonal and site allocation: a region-based study.

Heavy metals-mediated environmental pollution and global warming are two emerging threats to plant and human health worldwide. Several anthropogenic and natural activities with a preference for industrialization and heavy transportation have accelerated heavy metals and CO emissions into aerial and soil environments. For a few decades, woody trees have been considered an effective bioaccumulator or bioindicator tool for pollution assessment processes of air-born pollutants.

Impact of surface roughness and preheat temperature on fecrbmnsi coating properties prepared by the twin wire Arc spray method.

The purpose of this study is to evaluate the effects of substrate surface roughness (35 μm and 40 μm) and preheat temperature (50 °C, 100 °C, 150 °C) on the properties of the FeCrBMnSi coating layer applied to 304 stainless steels using the TWAS (Twin Wire Arc Spray) method. Surface preparation involved sandblasting and preheat treatment, followed by coating application with TWAS, and subsequent characterization using pull-off bonding, hardness, corrosion rate, Light Optical Microscope (LOM), and scanning electron microscopy (SEM) test. The current study's findings indicate that increasing preheat temperature and surface roughness consistently reduces the percentage of porosity, unmelted material, and coating layer thickness.

Insights into periodontal disease: comparative analysis of animal models.

Periodontal disease is a progressive condition characterized by the degradation of gingival tissues, periodontal ligaments, and alveolar bone, often resulting in tooth loss if untreated. Its pathogenesis is influenced by bacterial infections, host immune responses, and environmental factors. While human cell cultures provide insights into cellular mechanisms, animal models play a crucial role in understanding the complex host-pathogen interactions and developing therapeutic interventions.

How to Cope With Stress in the Desert-The Date Palm Approach.

Increasing desertification constitutes a global environmental problem, mainly driven by climate change and inappropriate land-use that limits agriculture, forestry and human colonization. The selection of suitable plant species to mitigate desertification is particularly challenging, as it usually requires simultaneous counteraction against a whole set of unfavourable environmental conditions, including heat, drought, high tropospheric ozone and salinity. It therefore seems useful to identify the survival strategies of plants native in desert environments.

Genes and proteins expressed at different life cycle stages in the model protist Euplotes vannus revealed by both transcriptomic and proteomic approaches.

Sexual reproduction first appeared in unicellular protists and has continued to be an essential biological process in almost all eukaryotes. Ciliated protists, which contain both germline and somatic genomes within a single cell, have evolved a special form of sexual reproduction called conjugation that involves mitosis, meiosis, fertilization, nuclear differentiation, genome rearrangement, and the development of unique cellular structures. The molecular basis and mechanisms of conjugation vary dramatically among ciliates, and many details of the process and its regulation are still largely unknown.
