Development of quantitative detection method for mass spectrometry coupled to an infrared laser spectroscope (Picarro) to monitor in nitrogen matrix a complex gas mixture of H , He, CO, N , Ne, O , Ar, CO , H S, CH , C H , C H , C H , C H , i-C H , n-C H , and C H.

Rationale: The deep geological repository is considered the international reference for radioactive waste management. All gas exchanges must be understood in the context of the feasibility of such a repository. The technological challenge is to continuously monitor a wide range of gaseous molecules at low concentrations in confined spaces.

Improvement of Heat Resistance of Fluorosilicone Rubber Employing Vinyl-Functionalized POSS as a Chemical Crosslinking Agent.

Fluorosilicone rubber (F-LSR) is a promising material that can be applied in various cutting-edge industries. However, the slightly lower thermal resistance of F-LSR compared with that of conventional PDMS is difficult to overcome by applying nonreactive conventional fillers that readily agglomerate owing to their incompatible structure. Polyhedral oligomeric silsesquioxane with vinyl groups (POSS-V) is a suitable material that may satisfy this requirement.

Correlation between acellular dermal matrix (ADM) volume and breast implant size selection among patients undergoing prepectoral direct-to-implant (DTI) breast reconstruction using complete ADM.

Background: In prepectoral direct-to-implant breast reconstruction using the acellular dermal matrix (ADM)-assisted technique, breast volume asymmetry can occur. We hypothesized that ADM size influences implant size selection in prepectoral breast reconstruction with implant coverage using an ADM. We investigated factors influencing implant size selection and provide guidelines for surgeons.

"Tear-Drop Appearance" Wrap: A Novel Implant Coverage Method for Creating Natural Contour in Prepectoral Prosthetic-Based Breast Reconstruction.

Various implant wrapping methods with acellular dermal matrix (ADM) have been introduced, but most focus on random trimming and suturing aimed to maximize implant coverage. Here we present our clinical experience using a "tear-drop appearance" wrapping method to achieve natural contours through upper pole volume replacement. We retrospectively reviewed the data of 56 consecutive cases of prepectoral prosthetic-based breast reconstruction (PPBR) using this wrapping method following nipple-sparing mastectomy between March 2020 and June 2021.

Review of 107 Oncoplastic Surgeries Using an Acellular Dermal Matrix with the Round Block Technique.

The round block technique (RBT) is an oncoplastic surgery method that uses volume displacement techniques after partial mastectomy. However, cosmetic problems occur after tissue rearrangement in patients with small breasts or those in whom a large amount of breast tissue is excised. Therefore, we used an acellular dermal matrix (ADM) when the volume was insufficient after tissue rearrangement.

Staged Chest Wall Reconstruction for Radiation-induced Costochondritis.

Costochondritis after breast reconstruction and radiation therapy is rarely reported. Moreover, it is difficult to diagnose using computed tomography and magnetic resonance imaging; as such, wound debridement and reconstruction must be performed in several stages. A 51-year-old woman was diagnosed with invasive cancer of the right breast, and she underwent nipple sparing mastectomy and direct-to-implant breast reconstruction in November 2007.

Factors Influencing Patient Satisfaction with Upper Blepharoplasty in Elderly Patients.

Unlabelled: Upper blepharoplasty in elderly patients has characteristics that differ from those of younger patients. Blepharoptosis in elderly patients causes not only aesthetic problems but also functional problems such as entropion, visual disturbance, and sore eyes. We hypothesized that factors influencing patient satisfaction with upper blepharoplasty in elderly patients include aesthetic outcomes, functional outcomes, and personal factors.
