Background: Large-scale retrospective studies have identified implicit gender bias in citation behaviors across multiple medical fields. There are minimal resources to directly assess one's own citation behavior before publication at a laboratory level. In this study, we performed an internal audit of our own citation practices and behavior, looking at the representation of authors by gender in our own bibliographies.

Background:  Preparation of the recipient vessels is a crucial step in autologous breast reconstruction, with limited opportunity for resident training intraoperatively. The Blue-Blood-infused porcine chest wall-a cadaveric pig thorax embedded in a mannequin shell, connected to a saline perfusion system-is a novel, cost-effective ($55) simulator of internal mammary artery (IMA) dissection and anastomosis intended to improve resident's comfort, safety, and expertise with all steps of this procedure. The purpose of this study was to assess the effect of the use of this chest wall model on resident's confidence in performing dissection and anastomosis of the IMA, as well as obtain resident's and faculty's perspectives on model realism and utility.

Breast implants are used for a wide range of cosmetic and reconstructive purposes. In addition to breast augmentation, implants can be used for postmastectomy breast reconstruction, correction of congenital breast anomalies, breast or chest wall deformities, and male-to-female top surgery. Breast implants may confer significant benefits to patients, but several factors are important to consider preoperatively, including the impact on mammography, future lactation, and potential long-term implant complications (e.

Introduction: Breast cancer is the most common cancer in women in Wisconsin. Evidence demonstrates that non-White racial minorities in the United States exhibit a higher mortality rate and more advanced or aggressive presentations of the disease than their White counterparts. Postmastectomy breast reconstruction remains essential to the treatment and recovery of these patients; however, racial disparities in the receipt of reconstruction are evident.

We recently reported that T-DM1-resistant JIMT1 (T-DM1R-JIMT1) cells exhibited high invasive activity via EGFR and integrin cooperated pathways and gained cross-resistance to doxorubicin. Here, we show that EGFR positively coordinates with MRP1 in T-DM1R-JIMT1 cells to contribute to cross-resistance to doxorubicin. Downregulating EGFR and MRP1 inhibits T-DM1R-JIMT1 cell growth and re-sensitizes T-DM1R cells to doxorubicin, suggesting that dual targeting EGFR and MRP1 could serve as a therapeutic approach to overcome T-DM1 resistance.

Background:  The high level of technical skill required by microsurgical procedures has prompted the development of in vitro educational models. Current models are cost-ineffective, unrealistic, or carry ethical implications and are utilized as isolated experiences within single surgical specialties. The purpose of this study was to assess the educational and interprofessional effect of a microsurgical training course utilizing the nonliving "Blue-Blood" chicken thigh model (BBCTM) in a multidisciplinary environment.

Background: Although atopic dermatitis (AD) often starts in early childhood, detailed tissue profiling of early-onset AD in children is lacking, hindering therapeutic development for this patient population with a particularly high unmet need for better treatments.

Objective: We sought to globally profile the skin of infants with AD compared with that of adults with AD and healthy control subjects.

Methods: We performed microarray, RT-PCR, and fluorescence microscopy studies in infants and young children (<5 years old) with early-onset AD (<6 months disease duration) compared with age-matched control subjects and adults with longstanding AD.

The presence of the dense hydroxyapatite matrix within human bone limits the applicability of conventional protocols for protein extraction. This has hindered the complete and accurate characterization of the human bone proteome thus far, leaving many bone-related disorders poorly understood. We sought to refine an existing method of protein extraction from mouse bone to extract whole proteins of varying molecular weights from human cranial bone.

Background: Little is known about the role of osteoclasts in cranial suture fusion. Osteoclasts are predominantly regulated by receptor activator of nuclear factor kappa B and receptor activator of nuclear factor kappa B ligand, both of which lead to osteoclast differentiation, activation, and survival; and osteoprotegerin, a soluble inhibitor of receptor activator of nuclear factor kappa B. The authors' work examines the role of osteoprotegerin in this process using knockout technology.
