The need to study the properties of the different materials used for these processes comprehensively and in detail has become a primary goal in order to get the best out of the manufacturing itself. The widely used thermoplastic polymer material acrylonitrile butadiene styrene (ABS) was selected in the form of both filaments and ABS-like resins to investigate and compare the mechanical properties through a series of different tests.

Nasal Construction in Congenital Arhinia Due to Novel SMCHD1 Gene Variant.

Arhinia, or congenital absence of the nose, is an exceedingly rare anomaly caused by pathogenic variants in the gene SMCHD1 . Arhinia exhibits unique reconstructive challenges, as the midface is deficient in skeletal and soft tissue structures. The authors present 2 related patients with arhinia who harbor a novel SMCHD1 gene variant and illustrate their surgical midface and nasal construction.

T-cell engineered with a fully humanized B-cell maturation antigen-specific T-cell antigen coupler receptor effectively target multiple myeloma.

B-cell maturation antigen (BCMA) is a clinically validated target for multiple myeloma. T-cell engineered with chimeric antigen receptors (CARs) directed against BCMA have demonstrated robust therapeutic activity in clinical trials, but toxicities remain a significant concern for a subset of patients, supporting continued investigation of other engineered T-cell platforms that may offer equal efficacy with an improved toxicity profile. The authors recently described a BCMA-specific, T-cell-centric synthetic antigen receptor, the T-cell antigen coupler (TAC) receptor, that can be used to engineer T-cell with robust anti-myeloma activity.

Pediatric Postburn Ear Reconstruction of Significant Cartilage Defects.

The external ear is a vulnerable appendage susceptible to trauma. Repairing and recreating its intricate architecture presents a formidable challenge after burn injury, especially when scar tissue, impaired vasculature, and damage to cartilage all influence reconstructive options. The authors share their institutional experience and provide a guide for reconstruction of significant postburn auricular cartilage defects.

Topical therapy for regression and melanoma prevention of congenital giant nevi.

Giant congenital melanocytic nevi are NRAS-driven proliferations that may cover up to 80% of the body surface. Their most dangerous consequence is progression to melanoma. This risk often triggers preemptive extensive surgical excisions in childhood, producing severe lifelong challenges.

Evaluation of liposomal bupivacaine infiltration at reconstructive skin graft donor sites in adolescent and young adult burn patients: A retrospective analysis.

Background: Postoperative pain at skin graft donor sites is frequently undertreated in burn patients, which can impair reconstructive outcomes and result in harmful psychological consequences. We find a critical need to explore and promote non-opioid, multimodal analgesics. Donor site infiltration of the local anesthetic liposomal bupivacaine in adolescent and young adult burn patients has not been previously investigated.

Manufacturing T cells in hollow fiber membrane bioreactors changes their programming and enhances their potency.

Engineered T cell therapies have revolutionized modern oncology, however processes for manufacturing T cell therapies vary and the impact of manufacturing processes On the cell product is poorly understood. Herein, we have used a commercially available hollow fiber membrane bioreactor (HFMBR) operated in a novel mode to demonstrate that T cells can be engineered with lentiviruses, grown to very high densities, and washed and harvested in a single, small volume bioreactor that is readily amenable to automation. Manufacturing within the HFMBR dramatically changed the programming of the T cells and yielded a product with greater therapeutic potency than T cells produced using the standard manual method.

Antegrade Foreheadplasty: A Novel Surgical Approach for Upper Eyelid Contracture Deformities in Pediatric Patients.

The intricate and delicate structure of the periorbital region, particularly in pediatric patients, presents challenges to eyelid reconstruction. Much like the more common lower eyelid ectropion, upper eyelid ectropion can result from lack of tissue, scar contracture, or over-resection as in blepharoplasty. In burns and trauma, the cause of cicatricial ectropion is typically direct scar contracture from injuries to the eyelid.

Properties of different types of dry electrodes for wearable smart monitoring devices.

Wearable smart monitors (WSMs) applied for the estimation of electrophysiological signals are of utmost interest for a non-stressed life. WSM which records heart muscle activities could signalize timely a life-threatening event. The heart muscle activities are typically recorded across the heart at the surface of the body; hence, a WSM monitor requires high-quality surface electrodes.

Triangular Fossa Graft for Philtral Reconstruction After Facial Burns: A 34-Year Experience.

Background: Upper lip burns and skin grafts used for the resulting deformities all contract, leading to distortion of regional tissues and producing a flattened upper lip devoid of normal anatomic landmarks. Absence of the philtral contour draws attention to the upper lip and can accentuate other reconstructive inadequacies. Philtral restoration requires a 3-dimensional reconstruction capable of resisting contractile forces to restore and maintain normal relationships between the upper and lower lips.
