Reflectance confocal microscopy is a non invasive imaging technique which provides in vivo and real time images of different skin tissues with a resolution close to histology, however with a depth limited to superficial dermis.The first lesions that were morphologically analyzed are melanocytic lesions. Reflectance confocal microscopy has been used for about ten years in dermatology. Its progressive improvement over the years has allowed it to be an efficient tool for diagnosing cutaneous tumors. It has been developed for inflammatory dermatosis, cutaneous infections, angiomas, cosmetology. Furthermore, it is also used to delimit the edges of lesions or the area to biopsy. This cutaneous imaging technique represents a major innovation and has its place in dermatological practice.

The retromer is a highly conserved eukaryotic complex formed by the cargo selective complex (CSC) and the sorting nexin (SNX) dimer subcomplexes. Its function is protein recycling and recovery from the endosomes to conduct the target molecules to the trans-Golgi network or the plasma membrane. The protozoan responsible for human amoebiasis, , exhibits an active membrane movement and voracious phagocytosis, events in which the retromer may be fully involved.

Lipopolysaccharide (LPS)-neutralizing peptides are emerging as new potential therapeutic modalities to treat sepsis and skin infections. Purinergic ligand-gated ion channels (P2X receptors) play a critical role in various biological processes, including inflammation. Recent drug development efforts have significantly focused on the modulation of P2X receptors.

In fiber-based confocal microscopy, using two separate fibers for illumination and collection enables the use of a few-mode fiber to achieve an effect similar to opening the pinhole in a conventional confocal microscope. In some Fourier-domain applications, however, or when a spectral measurement is involved, the coherent light detection would lead to noticeable spectral modulation artifacts that result from differential mode delay, an effect caused by the multimode propagation in the collection fiber. After eliminating these artifacts by using mode-dependent polarization control, we demonstrate effective spectrally encoded imaging with improved signal efficiency and lower speckle noise, and only a minor, negligible reduction in lateral and axial resolutions.

Background: Development of novel chiral antifungal agents for effective control of plant pathogens is urgently needed. In this study, a series of pyrazol-5-yl-benzamide derivatives containing chiral oxazoline moiety were rationally designed and developed based on molecular docking.
Results: The in vitro antifungal assay results indicated that compounds (rac)-4h (R = Et), (S)-4 h (R = S-Et) and (R)-4 h (R = R-Et) exhibited remarkable antifungal activities against Valsa mali with median effective concentration (EC) values of 0.

In this study, we evaluated the combined effect between MLE-15, a modular lytic enzyme composed of four building blocks, and reline, a natural deep eutectic solvent. The bioinformatic analysis allowed us to determine the spatial architecture of MLE-15, whose components were bactericidal peptide cecropin A connected via a flexible linker to the cell wall binding domain (CBD) of mesophilic 201ϕ2 - 1 endolysin and catalytic domain (EAD) of highly thermostable Ph2119 endolysin. The modular enzyme showed high thermostability with the melting temperature of 93.
