Methane (CH), carbon dioxide (CO), and oxygen (O) are the major gases produced by dairy cattle as a result of rumen fermentation and metabolism, and thus, their concentrations are frequently measured as a way of estimating heat production and energy metabolism. A well-utilized method of measuring gas consumption and production to estimate heat production is indirect calorimetry, which requires bags to retain the sampled gases until analysis. The objective of this study was to determine the ability of a polyvinyl fluoride gas bag (PF) and a multilayer fabrication gas bag containing an aluminum layer (NAP) to maintain respiratory gas composition in comparison to a polyethylene terephthalate bag (PET).

Introduction: This study investigated the impact of jaw resection (JR) and neck dissection (ND) on the incidence of jaw osteoradionecrosis (JORN) in patients with head and neck cancer (HNC) who underwent head and neck radiotherapy (HNR) involving the jawbone with/without ablative surgery. Evidence on this association remains scarce.
Materials And Methods: This retrospective study examined irradiated HNC patients treated at a German university hospital between 2007 and 2022, with follow-up until December 2024.

Despite the fact that articaine is one of the most commonly used LA in dentistry, a survey of documented cases of allergies to articaine is absent from the literature. The objective of this review was to ascertain how often true allergies to articaine, verified by standard allergological procedures, have been reported over the last 25 years.
