The recent global spread of the pandemic underscores the necessity of seeking new materials effective against microorganisms. Nanotechnology offers avenues for developing multifunctional materials. In this study, alpha-titanium phosphate (α-TiP) nanoparticles were synthesized and treated with silver salt to enhance their antimicrobial properties. The physicochemical characteristics and antimicrobial activity were evaluated. It was revealed by X-ray diffraction analysis that the structural integrity of α-TiP was influenced by ethylenediamine and silver ions. Distinct degradation profiles for each chemical modification were shown by thermogravimetric analysis. Infrared spectroscopy detected shifts and new absorption peaks in the spectra depending on the type of modification. Energy dispersive spectroscopy confirmed the disaggregation of α-TiP galleries following the addition of silver salt, which increased their effectiveness against microorganisms. Notably, only the sample treated with silver ions exhibited antimicrobial action. antimicrobial activity was tested against the bacteria of medical importance Escherichia coli, Salmonella Enteritidis, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus cereus, Listeria momocytogenes and the yeast Candida albicans. All microorganisms were inhibited by sample containing silver. Minor inhibition was observed against the Gram-positive bacteria L. monocytogenes and Bacillus cereus, while the greatest inhibition occurred against the fungus (yeast) C. albicans. The results revealed a potential application of the nanoparticles for control of microorganisms in public health.

AIM： To investigate a potential protective role of the kinin B2 receptor in a glycerol-induced rhabdomyolysis mouse model. METHODS： We separated 28 C57Bl/6 male mice into 4 groups： untreated WT animals, untreated B2 knockout mice, glycerol-treated WT and glycerol-treated B2 knockout mice. Glycerol-treated animals received one intramuscular injections of glycerol solution （50% v/v, 7 mL/kg）. After 48 h, urine and blood samples were collected to measure creatinine and urea levels. Addi-tionally, kidney samples were extracted for histological evaluation, and the mRNA expression levels of kinin B1 and B2 receptors and infammatory mediators were measured by real-time polymerase chain reaction. RESULTS： Serum creatinine and urea levels showed differences between untreated wild-type and glycerol-treated wild-type mice （0.66 ± 0.04 vs 2.61 ± 0.53 mg/dL, P 〈 0.01; and 33.51 ± 2.08 vs 330.2 ± 77.7 mg/dL, P 〈 0.005）, and between untreated B2 knock-out mice and glycerol-treated knockout mice （0.56 ± 0.03 vs 2.23 ± 0.87 mg/dL, P 〈 0.05; and 42.49 ± 3.2 vs 327.2 ± 58.4 mg/dL, P 〈 0.01）, but there was no difference between the glycerol-treated wild-type and glycerol-treated knockout mice. Glycerol was able to in-duce a striking increase in kinin B2 receptor expression （〉 30 times, 31.34 ± 8.9） in kidney. Animals injected with glycerol had a higher degree of tubular injury than untreated animals. Wild-type and knockout mice treat-ed with glycerol intramuscularly present kidney injury, with impairment in renal function. However, B2 knock-out mice treated with glycerol did not show a different phenotype regarding kidney injury markers, when com-pared to the wild-type glycerol-treated group. CONCLUSION： We conclude that the kinin B2 receptordoes not have a protective role in renal injury.

In the last years, the production of optical fibers cables has made possible the development of a range of spectroscopic probes for in situ analysis performing beyond nondestructive tests, environmental monitoring, security investigation, application in radiotherapy for dose monitoring, verification and validation. In this work, a system using an optical fiber cable to electromagnetic signal transmission from a NaI（TI） radiation detector is presented. The innovative device takes advantage mainly of the optical fibers large passband, small signal attenuation and immunity to electromagnetic interference to application for radiation detection systems. The main aim was to simplify the detection system making it to reach areas where the conventional device cannot access due to its lack of mobility and external dimensions. Some tests with this innovative system are presented and the results stimulate the continuity of the researches.
