1. In vivo reflectance confocal microscopic findings in a case of trichofolliculoma
Abstract Trichofolliculoma is a rare follicular hamartoma whose dermoscopic features have been scarcely reported. On the other hand, reflectance confocal microscopy features have not been described yet. In the present study, the authors report reflectance confocal microscopy features in a case of trichofolliculoma as squamous hyperplasia forming irregular fi

2. Synthesis and SARS-CoV-2 3CL Protease Inhibitory Effects of Oxazolidinone Derivatives
The 3-chymotrypsin-like protease (3CLpro) is an attractive target for the development of anti-SARS (severe acute respiratory syndrome) drugs. In this work, a series of oxazolidinone derivatives 3a-3v were synthesized and their inhibitory activities against SARS coronavirus 2 (SARS-CoV-2) 3CLpro were evaluated by the fluorescence resonance energy transfer (FR

3. Gas permeability and compressive strength evaluation of porous Al2O3 supported membrane
Abstract The aim was to investigate the feasibility of using a device to characterize permeability in porous substrates with low gas flux. Al2O3 supports were prepared by dry pressing using 1 to 3 wt% of polyethylene glycol (PEG) as a pore-forming agent. The green body was partially sintered at 1300 ºC. CO2 gas was used to measure both the pressure loss and

4. UMA NOTA SOBRE A TRANSPOSIÇÃO DE TERMOS QUÍMICOS PARA A LÍNGUA PORTUGUESA
This note has the purpose of calling the attention of the chemist to some aspects of the process of translating chemical terms onto the Portuguese language. A quick inspection on the chemistry literature in Portuguese shows a certain number of inadequate or dubious translations of terms originally coined in other languages. Firstly, the possible origins of t

5. Characterization and potential applications of new boron-phosphate glass in the CaO-P2O5-K2O-B2O3 system
Abstract Boron phosphate glasses are known for their unique properties and have been investigated as biodegradable materials for biomedical applications. In this context, the present research studied the characterization of physical, mechanical, and bioactive properties of new boron-phosphate glass in the CaO-P2O5-K2O-B2O3 system produced by the melt-quenchi

6. Development of a ceramic membrane for emulsion water-diesel treatment
Abstract The purpose of this study was the development of a low-cost ceramic tubular membrane, using inexpensive materials, namely natural clay, and graphite as a porogenic agent. Such a low-cost membrane can be used as filters or porous supports for the preparation of multilayer ceramic membranes. Extrusion was used as a shape-forming method for this purpos

7. Anabolic therapy for osteoporosis: update on efficacy and safety
ABSTRACT Anabolic agents for the treatment of osteoporosis increase bone density, improve bone strength, and reduce fracture risk. They are distinguished from antiresorptive drugs by their property of increasing osteoblastic bone formation. Teriparatide and abaloparatide are parathyroid hormone receptor agonists that increase bone remodeling with bone format

10. COMPREENDENDO OS MECANISMOS DE CORROSÃO DE LIGAS DE AL-CU-LI: UMA INVESTIGAÇÃO ATRAVÉS DE TÉCNICAS ELETROQUÍMICAS GLOBAIS E LOCAIS
In this study, the corrosion mechanism of an Al-Cu-Li alloy manufactured by two different treatment routes (T3 and T851) was evaluated by immersion and electrochemical tests in solutions containing chloride ions (Cl-). For both alloys, the formation of cavities on the surface was associated with micrometer-sized intermetallics (IM’s), however, in addition
