A device is described and evaluated for the anaerobic transport of clinical specimens. The device limits the amount of oxygen entering with the sample to a maximum of 2%, which is rapidly removed by reacting with hydrogen in the presence of a palladium catalyst. The viability on swabs of 12 species of anaerobes, four strains of facultative anaerobes and a strain of Pseudomonas aeruginosa, was maintained during the length of the tests (24 or 48 h). The results demonstrated that this device protected even the more oxygen-sensitive clinical anaerobes from death due to oxygen exposure. This device can be used for swabs as well as for anaerobic collection and liquid and solid specimens.

Some technical limitations to using the eccentric mode to measure peak eccentric strength of the hamstrings (PTH) were raised. PTH also has limited validity to predict performance or injury risk factor. Therefore, our aim was to compare PTH and other isokinetic variables tested in the eccentric and passive modes.

Due to their superior physicochemical features, chitosan thermosensitive hydrogels are multipurpose platforms that are frequently used in the biomedical industry. Many investigations have been conducted recently to modify their pore dimensions, expansion, biodegradability, stimulus-reaction characteristics, and other characteristics in order to better tailor them to the complex craniofacial tissues. They have been the focus of various studies that have attempted to load biological cargos for therapeutic and regenerative uses in the oro-facial tissues.

Objective: The optimal method for maintaining intraoperative blood pressure during microsurgical procedures remains controversial. While intravenous fluid administration is essential, overfilling can lead to complications. Vasopressor agents are used cautiously due to their vasoconstrictive effects, which could potentially lead to flap failure.

Objectives: To evaluate the treatment of peri-implant mucositis (PM) using a nonsurgical submarginal peri-implant instrumentation (NSPI) with or without chlorhexidine (CHX) solutions.
Methods: Fifty-six patients (28 per group) were randomly assigned to the test (NSPI + 0.12% mouthwash and subgingival CHX irrigation plus tongue brushing with 1% CHX gel) or the control group (NSPI + placebo mouthwash and subgingival placebo irrigation plus tongue brushing with placebo gel).
