Evaluation of the accuracy of dynamic navigation versus robot-assisted dental implant placement in models with one missing tooth or multiple missing teeth with a free-end: an in vitro study.

Objectives: To assess and compare the accuracy of robot-assisted and dynamic navigation systems for dental implant placement in models with either a single missing tooth or multiple consecutive missing teeth at the distal extension.

Methods: Thirty-two models and 86 implants were utilized. Implant placement was randomly assigned using either a robot-assisted or dynamic navigation system.

Evaluating the accuracy of a novel marker-free registration technique for dynamic computer-assisted implant surgery: An in vitro study.

Objectives: To propose a novel marker-free cusp-and-surface registration (CSR) technique for dynamic computer-assisted implant surgery (dCAIS) and to evaluate its accuracy in vitro.

Methods: Forty implants were inserted into twenty 3D-printed models designed to simulate maxillary anterior partial edentulism, using a dynamic navigation system that employed either the CSR or cusp registration (CR) technique. The CR group employed six reference points on six teeth adjacent to the edentulous ridge as reference structures.

Risk factors for drug-resistant epilepsy: A systematic review and meta-analysis.

Background: Drug resistant epilepsy (DRE) is very common among children and adults and studies had found some related risk factors for DRE, while the results were not consistent. The aim of this study was to identify risk factors for drug-resistant epilepsy.

Methods: Three electronic databases (Medline, Embase and Cochrane library) were searched to identify studies with a cohort design reporting on epidemiologic evidence regarding risk factors for DRE.

The efficacy of repetitive transcranial magnetic stimulation for Parkinson disease patients with depression.

To evaluate the efficacy of repetitive transcranial magnetic stimulation for Parkinson disease (PD) patients with depression. A meta-analysis was performed using relevant randomized controlled trials (RCTs) from online databases such as PubMed, Embase, Cochrane Online Library, and Clinicaltrials.gov.

Indirect comparison of third-generation antiepileptic drugs as adjunctive treatment for uncontrolled focal epilepsy.

Purpose: Eslicarbazepine (ESL), Lacosamide (LAC), Perampanel (PER) and Brivaracetam (BRV), have recently been marketed as third-generation antiepileptic drugs (AEDs). We conducted a meta-analysis to indirectly compare overall efficacy and tolerability between third-generation AEDs in uncontrolled focal epilepsy.

Methods: We performed an online database search using Pubmed, Embase, Cochrane Online Library, and Clinicaltrial.

Mesencephalic astrocyte-derived neurotrophic factor and its role in nervous system disease.

Mesencephalic astrocyte-derived neurotrophic factor (MANF) is a member of the novel evolutionary conserved neurotrophic factor (NTF) family. MANF has a unique structure and an unparalleled dual mode of action that differs from other known NTFs. Recent studies have shown that MANF protects cells from endoplasmic reticulum stress.

Expression and characterization of ArgR, an arginine regulatory protein in Corynebacterium crenatum.

Objective: Corynebacterium crenatum MT, a mutant from C. crenatum AS 1.542 with a lethal argR gene, exhibits high arginine production.

Effects and mechanism of hyperbaric oxygen on prostaglandins in alveolar bone and gingival of experimental periodontitis in animal.

Objective: To study the effects and the therapeutic mechanism of hyperbaric oxygen (HBO) on prostaglandin E(2) (PGE(2)) in alveolar bone and gingiva of experimental periodontitis in animal.

Methods: Experimental periodontitis was produced by silk thread sutures combined with high content sugar diet. For HBO therapy, they were exposed to a pressure of 0.
