Designing mouthwash formulations with innovative molecular components to control initial dental erosion in vivo.

Objective: This study aimed to examine and compare the efficacy of mouthwashes containing different proteins and peptide on the prevention of enamel erosion in vivo, as well as to evaluate the participants' satisfaction with the formulations.

Methods: Twelve participants were selected and underwent five cross-over mouthwash phases: Water (control); 0.1 mg/mL CaneCPI-5; 0.

Liquid-liquid phase inclusion bodies in acute and persistent parainfluenaza virus type 5 infections.

Cytoplasmic inclusion bodies (IBs) are a common feature of single-stranded, non-segmented, negative-strand RNA virus (Mononegavirales) infections and are thought to be regions of active virus transcription and replication. Here we followed the dynamics of IB formation and maintenance in cells infected with persistent and lytic/acute variants of the paramyxovirus, parainfluenza virus type 5 (PIV5). We show that there is a rapid increase in the number of small inclusions bodies up until approximately 12 h post-infection.

Theoretical insights, degradation, and sub-lethal toxicity of thiamethoxam to the planarian Girardia tigrina.

Advanced oxidative processes, such as Photo-Fenton, transform organic contaminants due to the attack by radicals. In this context, the lethal and sub-lethal effects of the Cruiser® 350FS (CRZ) with the active ingredient thiamethoxam (TMX) were investigated using the planarian Girardia tigrina. Degradation of thiamethoxam by the Fenton process was also assessed by using theoretical studies and the efficiency of Solar-Fenton versus Fenton.

Review, Properties, and Synthesis of Single-Switch Non-Isolated DC-DC Converters with a Wide Conversion Range.

The cascaded connection of power converters extends conversion ranges but requires careful consideration due to high component count and efficiency concerns, as power is processed redundantly. Furthermore, using several active switches that must be turned on simultaneously may introduce significant drive and control complexity. To overcome this limitation, single-switch quadratic DC-DC converters have been proposed in the literature as a prominent choice for various applications, such as light-emitting diode (LED) drivers.

Ecotoxicological evaluation of effluent from bovine slaughterhouses disinfected by peracetic acid (PAA) using the bioindicator Girardia tigrina.

The evaluation of the ecotoxicological effects of the effluent after treatment with peracetic acid is relevant to help establish reference concentrations for the disinfection process and waste recovery. Therefore, the objective of this work was to evaluate the ecotoxicity of effluent from a bovine slaughterhouse treated with peracetic acid on Girardia tigrina. The toxicity bioassays for planaria were the acute test (LC) and chronic assays: locomotion, regeneration, reproduction and fertility.
