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. Sunscreen lotions in the dermatological prescription: review of concepts and controversies
Abstract The skin is regularly exposed to several environmental aggressions, including solar radiation, whose biological effects can induce sunburn, dyschromia, skin aging and cancer. Among the photoprotection measures, sunscreens comprise a relevant part of the strategy aimed to prevent solar radiation damage and, for effective action, the patient must adhe

3. Radioprotective Effect of Nigella Sativa Oil on Heart Tissues of Rats Exposed to Irradition
Abstract Background Various studies are ongoing related to the radioprotective agents. Herbal preparations are currently becoming popular because of their beneficial effects with fewer side effects compared to the synthetic/semi-synthetic medicines, and Nigella sativa oil (NSO) is only one of them. Objective To investigate NSO for its antioxidant effects

4. MICROPLÁSTICOS: USO NA INDÚSTRIA COSMÉTICA E IMPACTOS NO AMBIENTE AQUÁTICO
Environmental pollution from plastics and microplastics is currently one of the most relevant issues of the scientific community and cosmetic industry. In particular, microplastics are referred to as small pieces of plastic less than five millimeters (<5mm) and do not dissolve in water, can be harmful to the ocean and aquatic life. Microplastics can be desig

5. Photo-Fenton-Based Degradation of Methylene Blue Dye Using Hydroxyapatite Nanoparticles Doped with Fe3O4/γ-Fe2O3
In this study, we evaluated the catalytic properties of hydroxyapatite (HA) nanoparticles (NPs) doped with Fe3O4/γ-Fe2O3 for the degradation of methylene blue (MB) dye using a photo-Fenton process at pH 2.5, 7.0, and 9.0. The HA NPs were characterized using X-ray diffraction, scanning electron microscopy, Fourier-transform infrared spectrometry, Raman spect

6. Comparison of Clinical Examination and Various Imaging Modalities in the Diagnosis of Head and Neck Cancer
Abstract Introduction Squamous cell Carcinoma of the Head and Neck (HNSCC) is the most common tumor entity of malignant processes in the head and neck area. Due to the metastasizing behavior of these tumors, the staging is indispensable for the treatment planning and requires imaging techniques, which are sensitive, specific, and as far as possible cost-eff

7. EFFECTS OF PHOTOSELECTIVE SHADE NETS ON EARLY GROWTH OF SUGARCANE SEEDLINGS
ABSTRACT Sugarcane has a great economic interest in Brazil, so it needs technologies to increase its yield strength, especially for seedling production. This study aimed to ascertain the influence of shading nets on early growth and development of pre-sprouted sugarcane seedlings. An experiment was conducted in a protected environment, in the Rural Federal U

8. Effect of Different Thermal and Non-Thermal Processing Methods on Chemical Composition, Quality Indicators and Apparent Nutrient Digestibility of Full-Fat Soybean
ABSTRACT The aim of this research was to study the effect of thermal and non-thermal processing methods on chemical composition, quality indicators and apparent digestibility of soybean nutrients. For this, four processing methods (unprocessed, extruded, thermal, and gamma radiation) were applied on two soybean varieties (Katol & Caspian). Rations were formu

9. Albinism: epidemiology, genetics, cutaneous characterization, psychosocial factors
Abstract Oculocutaneous albinism is an autosomal recessive disease caused by the complete absence or decrease of melanin biosynthesis in melanocytes. Due to the reduction or absence of melanin, albinos are highly susceptible to the harmful effects of ultraviolet radiation and are at increased risk of actinic damage and skin cancer. In Brazil, as in other par

11. Effects of Gamma Radiation on the Properties of the Thermoplastic Starch/Poly (Butylene Adipate-co-Terephthalate) Blends
The development of blends made from matrices of synthetic biodegradable polymers, and natural additives, are considered less environmentally aggressive materials. This work aimed to study the effects of gamma radiation on the properties of the thermoplastic starch (TPS)/poly(butylene adipate-co-terephthalate) (PBAT). In this work, blends of TPS/PBAT were pre
