1. Therapeutics in Radiation-induced Proctopathy: A Systematic Review
Abstract Malignant neoplasms are increasingly prevalent in the daily clinical practice. Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to min

2. Argon Plasma Coagulation in Radiation-induced Proctitis
Abstract Background Argon plasma coagulation (APC) is a non-tactile ablative therapy that helps to stop rectal bleeding in patients who have developed actinic proctitis after exposure to radiotherapy. This approach seems to be more effective than medications or surgical procedures. Objective To review the literature to verify the effectiveness of APC in th

3. UVB irradiation differential regulate miRNAs expression in skin photoaging
Abstract Background: UVB irradiation can cause acute damage such as sunburn, or photoaging and melanoma, all of which are major health threats. Objective: This study was designed to investigate the mechanism of skin photoaging induced by UVB radiation in mice through the analysis of the differential expression of miRNAs. Methods: A UVB irradiation photoag

4. Evaluation of HIF-1α and VEGF-A expression in radiation-induced cystitis: A case-control study
ABSTRACT The standard treatment for locally advanced cervical cancer (CC) is chemoradiotherapy. Once the bladder receives part of the radiation, a typical inflammatory condition that configures radiation-induced cystitis may develop. Chronic radiation-induced cystitis is commonly characterized by the bladder new submucosal vascularization, which is typically

6. Evaluation of ex vivo melanogenic response to UVB, UVA, and visible light in facial melasma and unaffected adjacent skin,
Abstract Background: The independent role of solar radiation in the differential melanogenesis between melasma and adjacent skin is unknown. Objectives: To assess the melanogenic responses of skin with facial melasma and of the adjacent skin to UVB, UVA, and visible light, in an ex vivo model. Methods: This was a quasi-experimental study involving 22 pati

7. LABORATORY INVESTIGATION OF X-RAY PHOTOLYSIS OF METHANOL ICE AND ITS IMPLICATION ON ASTROPHYSICAL ENVIRONMENTS
Methanol (CH3OH) is one of the most abundant organic molecules in astrophysical environments. It has been found in cold regions such as surfaces of comets, ices near young stellar objects and protoplanetary disks, as well as in the gas phase in different regions in space. In this work, we experimentally simulate the methanol ice and its behavior when irradia

8. Standardization of organoid culture for evaluation of melanogenesis induced by UVB, UVA and visible light,
Abstract Background: Organoid cultures are primary cultures that maintain architectural characteristics and the relationships between cells, as well as the extracellular matrix. They are alternatives for pathophysiological or therapeutic investigation rather than animal and in vitro tests. Objective: Development of a cutaneous organoid culture model, aimin

9. Influence of High Light Intensity and Nitrate Deprivation on Growth and Biochemical Composition of the Marine Microalgae Isochrysis galbana
Abstract Isochrysis galbana is a brown microalgae widely used as a feed for marine organism in aquaculture. The aim of present study is to investigate the growth, biochemical composition, fatty acid profile, photosynthetic parameters and antioxidant activity (radical scavenging activity) of Isochrysis galbana cells cultivated under different levels (sub-opti

10. Influence of high-frequency microwave radiation on montmorillonite structure parameters
Resumo A influência da radiação micro-ondas nas alterações estruturais das partículas de montmorilonita foi estudada em uma amostra de argila montmorilonítica. Processos de longo alcance em múltiplas escalas foram induzidos nos aluminossilicatos naturais por radiação de micro-ondas de baixa e média potência (2,45 Hz, 750 W, 10 min). Amostras em p

12. Microhardness and Ultrastructure of Demineralized Gamma-Irradiated Human Enamel after Diode Laser (980 nm) and Fluoride Surface Treatment
Abstract Quality of life drastically diminished after radiotherapy due to radiation induced oral complications. Fluoride was found to be helpful in decreasing the incidence of radiation caries; however it has not led to elimination of dental caries. Thus, new techniques containing low fluoride concentration or not containing fluoride at all, as laser irradia
