Moreover, TiO2 NFs induced highest cell alterations in human lung epithelial cells exposed to 10 and 50 μg/cm2 while ITO NPs induced moderated cytotoxicity and SiO2 NPs caused even lower cytotoxicity under the same conditions. DNA, proteins and lipids were mainly affected by TiO2 NFs followed by SiO2 NPs with toxic effects in protein and lipids while limited variations were detected after exposure to ITO NPs on spectra analyzed by Fourier Transform Infrared Spectroscopy.The gut microbiota is a complex ecosystem of bacteria, fungi, and viruses that acts as a critical regulator in microbial, metabolic, and immune responses in the host organism. Imbalances in the gut microbiota, termed "dysbiosis," often induce aberrant immune responses, which in turn disrupt the local and systemic homeostasis of the host. Emerging evidence has highlighted the importance of gut microbiota in intestinal diseases, and more recently, in age-related central nervous systems diseases, for example, stroke and Alzheimer's disease. Amredobresib It is now generally recognized that gut microbiota significantly influences host behaviors and modulates the interaction between microbiota, gut, and brain, via the "microbiota-gut-brain axis." Several approaches have been utilized to reduce age-related dysbiosis in experimental models and in clinical studies. These include strategies to manipulate the microbiome via fecal microbiota transplantation, administration of prebiotics and probiotics, and dietary interventions. In this review, we explore both clinical and preclinical therapies for treating age-related dysbiosis.

Glyphosate is a broad-spectrum biocide and the active ingredient in the most widely used herbicides worldwide. Since 2015, when the International Agency for Research on Cancer classified it as a Class 2A carcinogen, global interest in this chemical spiked particularly as regards exposure of the general population.

An exploratory glyphosate exposure assessment was conducted among Portuguese adults.

Self-selected participants provided first morning urine which was tested for glyphosate and its metabolite aminomethylphosphonic acid (AMPA) at two distinct periods of time, by two different laboratories using gas chromatography with tandem mass spectrometry (GC-MS-MS) and high performance liquid chromatography linked to triple quadrupole mass spectrometry (HPLC-MS/MS), respectively.

In the first round of testing 28% and 50% presented detectable levels of glyphosate and AMPA respectively, with median values of 0.25 and 0.16 μg/L. Systematically available internal dose values were 8.20E-06 mg/Kg (glyphosate) ies in other European countries. Systematically available internal doses values were below EFSA's risk assessment values (ADI or AOEL), and as such, the concentration values measured in this study are not per se a human health problem. Even though there were study limitations, it is the first assessment in Portugal and contributes to the overall knowledge map of glyphosate exposure in Europe.Autologous CD19-directed chimeric antigen receptor T lymphocyte (CAR-T) therapy is an approved and effective treatment for the management of patients with refractory and multiply relapsed B cell precursor acute lymphoblastic leukemia (B-ALL). Experience using this therapy in pediatric patients with extramedullary (EM) disease is limited, in part because these patients have frequently been excluded from clinical trials owing to concerns for an increased risk of immune effector cell-associated neurotoxicity syndrome (ICANS). We infused 7 patients with refractory or multiply relapsed B-ALL who presented with isolated EM relapse with tisagenlecleucel. Six patients had isolated central nervous system (CNS) leukemia, and 1 patient had an isolated testicular relapse. An initial complete response was seen in all patients, with 5 patients remaining in CAR-T-induced remission at a median of 18 months from first infusion. Reversible ICANS was seen in 1 patient with CNS leukemia. Durable B cell aplasia occurred in 3 patients, with a median time to B cell recovery of 6.5 months in the other patients. These data suggest that CAR-T therapy has promising safety and efficacy in treating EM leukemia, although definitive conclusions are limited by the small size of the cohort and limited follow-up period.One of the most important features of optical biopsy methods is its non-invasive nature, high sensitivity and resolution in comparison to traditional diagnostic methods. Optical diagnostic methods, contrary to histopathological tests and biochemical analysis, do not require the collection of tissue samples for analysis, and the amount of analyzed material is practically unlimited. The aim of this study was to evaluate the usefulness of spectral studies in the diagnostics of skin basal cell cancer using a protoptive device in clinical conditions. Each of the subjects was measured 4 times. The measurements were performed on the skin of a patient without a photosensitizer and on the healthy skin on the opposite side of the change in relation to the middle line, also without a photosensitizer. Patients were then given photosensitizer in form of ointment from ALA (Sigma Aldrich, USA) and lubricated with this ointment with occlusal dressing. The patient was examined again 3 h after the application. In each case the measurement time was 1.2 s. Significant differences were observed for the measurements of the sick patient's skin with photosensitizer. Significant differences in spectral curve between 570 and 780 nm were observed.

Current standard skin antisepsis to prevent surgical site infections are ineffective to eradicate all skin-colonizing bacteria. Photodynamic therapy (PDT) has shown bactericidal effects in vitro, but no clinical study with improvements in skin antisepsis has been documented.

We investigated the effect of methyl aminolevulinate (MAL)-PDT versus no PDT for skin antisepsis treatment (povidone-iodine/alcohol) in the groin of 10 healthy participants. Skin swabs were taken at baseline, immediately after PDT, and after skin antisepsis treatment to cultivate bacteria. At day 7 and 21, bacterial cultures were repeated before and after antisepsis treatment without PDT. Skin biopsies were performed to examine the grade of inflammation.

Skin-colonizing bacteria were found in all 20 participants at baseline sampling. Immediately after MAL-PDT, skin was sterile in 7 (70%) participants before and in all 10 (100%) participants after skin antisepsis treatment. In contrast, we found skin-colonizing bacteria in 5 (50%) participants of the control group receiving only skin antisepsis.
