- The study aimed to compare two methods for reconstructing post-extraction bone defects: using a non-resorbable d-PTFE membrane left exposed versus guided bone regeneration (GBR) performed later, over a period of four weeks and two months, respectively.
- Conducted as a multicenter randomized controlled trial in Italy with 18 enrolled patients, the study found no instances of implant failure or complications, and all patients reported satisfaction with their implants.
- While histological analyses showed well-mineralized bone in both groups, the regenerated bone appeared more mature in the GBR group, though overall there were no significant differences in tissue volume between the two methods.
Critical materials such as rare earth underpin technologies needed for a decarbonized global economy. Recycling can mitigate the supply risks created by the increasing demand and net import dependence, and enable a circular economy for critical materials. In this study, we analyze the feasibility and life-cycle impacts of recovering critical materials from spent nickel metal hydride batteries from hybrid electric vehicles in the U.

Here, we present data regarding the decline of the SARS-CoV-2 BNT162b2 mRNA vaccine-induced humoral immune response in a monocentric cohort of MS patients.
Methods: 96 MS patients undergoing eight different DMTs, all without previous SARS-CoV-2 infection, were evaluated for anti-Spike IgG levels, 21 days (T1) and 5-6 months (T2) after the second SARS-CoV-2 BNT162b2 mRNA vaccine dose.
Background: Studying otolith functions after unilateral vestibular neuritis using ocular vestibular-evoked myogenic potentials and subjective visual vertical tests could give different results.
Method: A total of 39 patients underwent a vestibular assessment that included the Dizziness Handicap Inventory and horizontal and vertical semicircular canal function testing with video head impulse testing, ocular vestibular-evoked myogenic potential testing, cervical vestibular-evoked myogenic potentials and subjective visual vertical testing.
Results: All patients showed a significant alteration (asymmetry ratio more than 40 per cent) for ocular vestibular-evoked myogenic potentials as well as for subjective visual vertical testing (more than -2° to more than +2°) during the acute phase, whereas after 72 hours from the acute vertigo attack normal values (asymmetry ratio less than 40 per cent) were found in 6 out of 39 patients for ocular vestibular-evoked myogenic potentials and 36 out of 39 for the subjective visual vertical (less than -2° to less than +2°).
