Effectiveness of Dental Homecare Protocols in Unscaled Dogs.

Many dental homecare products are marketed, several of which have been evaluated using a "clean tooth" protocol (the teeth are scaled at the start of the trial). The efficacy of dental products in dogs that have not had their teeth professionally cleaned ("dirty tooth model") has been studied far less often. Some dogs for which professional dental cleaning is indicated will not have their teeth cleaned because of anesthetic risk or for other reasons.

An overview of the poisonous plants of Lebanon and their effects.

Poisonous plants are naturally found in the environment and are easily reachable especially by children. These plants pose significant risks ranging from mild or asymptomatic to severe and even life-threatening. Data on poisonous plants of Lebanon is scarce and scattered; therefore, there remains a significant gap in the literature concerning poisonous plants in Lebanon.

Direct Antivirals Can Achieve a Cure in All Patients With Chronic Hepatitis C due to Genotype 5: A French Multicentre Study.

Background: Hepatitis C virus genotype 5 (HCV-GT-5) is found mainly in South Africa. In our area in central France, the prevalence of HCV-GT-5 is 14%.

Methods And Results: Here we evaluated sustained virological response at week 12 post-treatment (SVR12) in 147 HCV-GT-5 patients from 14 French university hospitals (2014-2021) treated with direct-acting antivirals (DAA) in real-life.

Direct observation of the complex S(IV) equilibria at the liquid-vapor interface.

The multi-phase oxidation of S(IV) plays a crucial role in the atmosphere, leading to the formation of haze and severe pollution episodes. We here contribute to its understanding on a molecular level by reporting experimentally determined pK values of the various S(IV) tautomers and reaction barriers for SO formation pathways. Complementary state-of-the-art molecular-dynamics simulations reveal a depletion of bisulfite at low pH at the liquid-vapor interface, resulting in a different tautomer ratio at the interface compared to the bulk.
