Summary: Biomineralization refers to the process of mineral precipitation by living organisms. Recent research has found a connection between bacterial biofilms and the formation of calcium oxalate in kidney stones. This study discovered that a component of bacterial biofilm called levan can induce the formation of calcium oxalate crystals and has a stereospecific interaction with them. Understanding this effect may aid in the development of future treatments for kidney stone formation.

Summary: This article evaluates the electromagnetic field exposure from subterahertz antennas in a multilayer flat tissue phantom, demonstrating that the deposited electromagnetic fields can be evaluated by neglecting deep tissue in the simplified phantom. The temperature distribution in the full-size phantom can then be evaluated using the solution to the simplified electromagnetic problem to reduce computation time. Results show a good correlation between peak rising temperature and peak absorbed power density averaged over a small area.

Summary: A novel compact device with spectrum analyzer characteristics has been designed to measure the entire communications spectrum and detect multiple sources of electromagnetic fields. The device was calibrated in an anechoic chamber for far-fields and validated against a portable spectrum analyzer in a residential area, showing a strong correlation with a confidence higher than 95%. This indicates that the device could be considered as an important tool for electromagnetic field studies.

Summary: This study investigated the development of Blue Bottle Flies under exposure to RF-EMFs at 5.4 GHz. Numerical simulations and experiments were conducted to assess the impact on the development process. The results showed that the mass, length, and diameter of the pupae remained similar across different exposure conditions, but the total rate of pupal emergence was reduced under a specific RF-EMF exposure condition.

Summary: Fourier transform infrared micro-spectroscopy is a valuable tool for studying changes in human cells after exposure to ionizing radiation, and recent attention has been focused on its use in cells exposed to proton beams. The use of low-e-substrates slides for cell culture has been proposed to simplify and speed up the irradiation and measurements phases. Analyzing spectra obtained in transflection geometry reveals significant changes in DNA, lipids, and protein components of cells.

Summary: This study compares the FTIR spectra of different breast cell lines and finds significant differences in absorption spectra, particularly in the amide I and II bands and the intensity of nucleic acid bands. The ratio of certain peaks at specific wavenumbers is able to differentiate between non-malignant, malignant, and metastatic cells. These findings suggest that FTIR microspectroscopy has potential as a tool for cytological diagnosis of breast cancer.

Summary: The cellular response of a normal human keratinocyte cell line to non-cytotoxic doses of a deltamethrin-based pesticide was investigated using two electrical impedance spectroscopy techniques. The results showed that the membrane capacity and the impedance of the extracellular matrix increased with pesticide concentration, affecting electric current flow. Additionally, dielectric permittivity changes and an increase in neutral membrane lipids were observed in the cellular samples. Fluorescence measurements indicated a time increase in emission intensity, suggesting a membrane lipid response to repair cell damage caused by pesticide exposure. These spectroscopic techniques provide potential means for early diagnosis of cellular modifications related to pesticide exposure.

Summary: Fourier Transform Infrared (FTIR) microspectroscopy has shown great potential in cytological diagnostics as it provides rapid and label-free biochemical information about cell samples. The use of FTIR as a clinical tool has been hindered due to the incompatibility with glass slides commonly used in clinical practice. However, recent research has shown the possibility of obtaining diagnostic information from the IR absorption spectra in the 2700-3700 cm(-1) range. This study applies FTIR in this range to diagnose human colon cells and successfully distinguishes healthy cells from cancerous ones using principal component analysis (PCA) and classification models.
