Summary: The study evaluated the chemical and morphological changes of femtosecond laser-irradiated enamel using Raman spectroscopy, CLSM, and SEM. Results showed a significant decrease in carbonate content and carbonate/phosphate ratio in enamel after laser irradiation, without altering its structure and morphology.

Summary: This study examined the impact of mechanical stress on the pellicle of grass roots. Results showed that while mechanical stress caused microdamage in the epidermal layers, the pellicle played a protective role in preventing damage to the protodermal cells, thereby safeguarding the root apical meristem from negative effects.

Summary: This paper proposes multiscale characterization methods for additive manufactured surfaces using 3D topographic data at different resolutions. The methods involve point pattern analysis, roughness characterization, and feature-based characterization. The results demonstrate the different contributions of weld track features and particle features to surface roughness at different scales.

Summary: Fresh strawberries are popular and consumed frequently, but outbreaks caused by food-borne pathogens have been associated with their consumption. Salmonella enterica subsp. enterica serovar Thompson can form biofilms on the surface of strawberries during storage, which allows the bacteria to survive and spread. This is crucial for food safety.

Summary: The study thoroughly examined the morphology of the male genitalia of head lice Pediculus humanus capitis using stereoscopic microscopy, confocal laser scanning microscopy, and scanning electron microscopy. The results revealed the complex structures and characteristics of the genitalia at different stages of copulation, providing valuable information for future research on lice genitalia and impacting taxonomic and phylogenetic studies of other insect taxa.

Summary: The paper introduces a method for detecting subsurface damage (SSD) in large polished optics that is difficult to observe, using confocal laser scanning and three-dimensional reconstruction techniques. This method can quickly and accurately display the morphology of SSDs and provide quantitative evaluations of SSDs.

Summary: Correlative multimodal imaging is a valuable method for investigating complex structural relations in life sciences. It requires establishing sample preparation workflows that are compatible with multiple imaging techniques. This can involve imaging a fluorescently labeled region of interest in a biological soft tissue sample with light microscopy before staining the specimen with heavy metals for higher resolution structural imaging.

Summary: This study presents technical advances in using lab-based X-ray microscopy for high-resolution 3D imaging of plant samples at multiple scales. Serial imaging and improved sample preparation methods allow for the generation of sub-micron 3D volumes co-registered with lower magnification scans, providing explicit contextual reference. This method bridges the imaging gap between light and electron microscopy and can be applied to various economically and scientifically important plant systems.

Summary: The chemical profile and phytotoxicity of Artemisia absinthium essential oil were investigated, identifying linalool as the major active compound responsible for its suppressive activity on receiver species. This study highlights the potential value of the essential oil and its major constituents as environmentally friendly herbicides.

Summary: This study investigated the accumulation potential of aluminum at the subcellular level and its ultrastructural toxicity in submerged plants. The results showed that severe structural and ultrastructural damage occurred when plants were exposed to aluminum concentrations of 0.6 mg/L or higher. At a concentration of 1.5 mg/L, aluminum could be transferred from the roots to other parts of the plant, with the aged leaves being the most receptive tissues.

Summary: The muscid genera Alluaudinella, Aethiopomyia, and Ochromusca share a monophyletic relationship supported by morphology and feeding strategy. Previous studies have provided conflicting hypotheses about their subfamilial position within Muscidae. Through larval morphology, biology, and molecular data, the systematic position of Alluaudinella and its related genera is revised, suggesting a transfer to the subfamily Reinwardtiinae.

Summary: A novel NIR-II CLSM system has been developed using inexpensive SiPM for multicolor biological imaging in vivo, achieving spatial resolution close to the diffraction limit and very low fluorescence detection sensitivity. Experiments in mice demonstrated comparable multicolor imaging performance in both NIR-I and NIR-II windows.

Summary: The study found that pomegranate fruits are prone to moisture loss during storage, leading to compromised visual appearance and financial loss. Factors contributing to water loss include increased count of lenticels, widening of micro-cracks, and fragmentation of waxy cuticle. Differences in peel tissue thickness and structure at different parts of the fruit also affect water loss trends.
