Raman spectroscopy and infrared (IR) are both techniques that allow for the investigation of vibrating chemical particles. These provide information not only about particles through identification functional groups spectral analysis so-called "fingerprints", these methods qualitative quantitative analyses substances in sample. Both frequently being used biology medicine diagnosing illnesses monitoring therapy. The type breast cancer found woman is often a malignant tumor, causing 1.38...
Abstract Platinum-resistant phenomena in ovarian cancer is very dangerous for women suffering from this disease, because reduces the chances of complete recovery. Unfortunately, until now there are no methods to verify whether a woman with platinum-resistant. Importantly, histopathology images also were not shown differences between platinum-resistant and platinum-sensitive tissues. Therefore, study, Fourier Transform InfraRed (FTIR) FT-Raman spectroscopy techniques used find chemical...
Early detection of the most common pediatric neoplasm, B-cell precursor lymphoblastic leukemia (BCP-ALL), is challenging and requires invasive bone marrow biopsies. The purpose this study was to establish new biomarkers for early screening detect leukemia. In small cohort study, Fourier transform infrared (FTIR) spectra were obtained from blood sera 10 patients with BCP-ALL compared control samples children some conditions other than neoplasm. Using various analytical approaches, including a...
Abstract Triple-negative breast cancer is the most aggressive subtype with limited treatment options and a poor prognosis. Approximately 70% of triple-negative patients fail to achieve pathologic complete response (pCR) after chemotherapy due lack targeted therapies for this subtype. We report here development focal-plane-array Fourier transform infrared (FPA-FTIR) microspectroscopic technique combined principal component analysis (PCA) monitoring effects in patients. The PCA results...
<title>Abstract</title> Hundreds of thousands cubic meters legacy radioactive waste from plutonium production stored at U.S. Department Energy’s Hanford site will be immobilized in glass for disposal. The must limit radionuclide release into the environment years, which is challenging to assess laboratory experiments. Long-term alteration behavior analogue glasses can demonstrate how perform over extended periods. Glasses buried hundreds years climatically variable sites were selected...
The emergence of antibiotic-resistant strains caused by the extensive use antibiotics in world requires a preventive approach to stop infection spread, especially hospital setting. So, there is growing demand for materials that can inhibit bacteria growth or have bactericidal effects. In this paper, an inexpensive and durable Cu-containing strontium-modified phosphate glass with considerable antimicrobial effect proposed. basic physical properties material are studied, its evaluated on...
Mixed Se-Te glasses are unique materials for infrared optical applications due to their exceptional IR transparency, molding and fiber-drawing capability, environmental stability, tailored physical properties. In this work, the effect of gradual substitution Sb with P in bulk PxGa5Ge20Sb10-xSe45Te20 is studied structural methods, spectroscopy, differential scanning calorimetry (DSC). Non-isothermal isothermal DSC studies reveal crystallization several phases, some them following...
Abstract Chronic sleep deprivation (SD) impairscognitive function and promotes neurodegenerative changes, particularly in thehippocampus prefrontal cortex. Study investigates the biochemical andimmunological effects of SD evaluates neuroprotective properties ofmelatonin using Fourier Transform Raman (FT‐Raman) spectroscopy. Hippocampaland cortical tissues from four groups micecontrol, melatonin‐treated, sleep‐deprived, sleep‐deprived with melatoninwere analyzed. FT‐Ramanspectra revealed...
ABSTRACT Chronic alcohol consumption significantly impacts physiological and neurological functions. This study aimed to investigate the biochemical alterations in serum associated with long‐term use using Fourier Transform Infrared (FTIR) spectroscopy. Serum samples from control disorder (AUD) were analyzed, their spectra compared. Multivariate analysis techniques, including Principal Component Analysis (PCA) Hierarchical Cluster (HCA), employed differentiate groups. A machine learning...

Also, dependence ac conductivity frequency, temperature, concentration investigated. Based the curves conductivity, dc was calculated, 400 % enhancement in exposed.
The differential diagnosis of Ewing sarcoma and osteomyelitis can be challenging lead to delays in treatment with possibly devastating results. In this retrospective, small-cohort study we demonstrate, that the Fourier Transformed Infrared (FTIR) spectra bone tissue differentiated from normal sampled outside tumour area. Significant differences samples seen lipid protein composition. Supervised learning using a quadratic discriminant analysis classifier was able differentiate high accuracy....
Abstract Mn 2+ and the trivalent europium (Eu 3+ )-doped MgGa 2 O 4 ceramics are characterized using a multi-experimental approach. The formation of spinel-structured is ascertained from X-ray diffraction (XRD) analysis. Morphology investigations with transmission electron microscopy (TEM) show irregularly shaped grains grain boundaries homogeneous distribution Eu ions. inability activator to penetrate bulk ceramic inferred positron annihilation lifetime spectroscopy data. doping shown...
Currently, endometrial carcinoma (EC) is the most common genital cancer in high-income countries. Some types of hyperplasia (EH) may be progressing to this malignancy. The diagnosis EC and EH based on time consuming histopathology evaluation, which subjective causes discrepancies reassessment. Therefore, there a need create methods objective evaluation allowing early changes. study aimed simultaneously asses Fourier Transform Infrared (FTIR) Raman spectroscopy combined with multidimensional...
Abstract Phase-change materials, demonstrating a rapid switching between two distinct states with sharp contrast in electrical, optical or magnetic properties, are vital for modern photonic and electronic devices. To date, this effect is observed chalcogenide compounds based on Se, Te both, most recently stoichiometric Sb 2 S 3 composition. Yet, to achieve best integrability into photonics electronics, the mixed S/Se/Te phase change medium needed, which would allow wide tuning range such...
