Oncolytic alphavirus-induced extracellular vesicles counteract the immunosuppressive effect of melanoma-derived extracellular vesicles.

Extracellular vesicles (EVs)-mediated communication by cancer cells contributes towards the pro-tumoral reprogramming of the tumor microenvironment. Viral infection has been observed to alter the biogenesis and cargo of EVs secreted from host cells in the context of infectious biology. However, the impact of oncolytic viruses on the cargo and function of EVs released by cancer cells remains unknown.

Mannose-6-Phosphate Isomerase Functional Status Shapes a Rearrangement in the Proteome and Degradome of Mannose-Treated Melanoma Cells.

Metabolic reprogramming is a ubiquitous feature of transformed cells, comprising one of the hallmarks of cancer and enabling neoplastic cells to adapt to new environments. Accumulated evidence reports on the failure of some neoplastic cells to convert mannose-6-phosphate into fructose-6-phosphate, thereby impairing tumor growth in cells displaying low levels of mannose-6-phosphate isomerase (MPI). Thus, we performed functional analyses and profiled the proteome landscape and the repertoire of substrates of proteases (degradome) of melanoma cell lines with distinct mutational backgrounds submitted to treatment with mannose.

Penile Inversion Vaginoplasty: An Evolving Technique.

Penile inversion vaginoplasty (PIV) is the most common surgical technique used in "gender-affirming bottom surgery." During this process, penile tissue is used to create a functional neo-vagina, allowing the individual to experience a more aligned physical manifestation of their "gender" identity. In this technical note, we describe the steps and nuances used by the senior author to ensure reliable aesthetic and functional outcomes, contributing to the overall well-being and satisfaction of transgender patients.

"Prepectoral tissue expanders without mesh as a bridge to delayed autologous breast reconstruction: Experience at a single academic center".

Acellular dermal matrix (ADM) is a useful adjunct in implant-based breast reconstruction. The benefits of using ADM with an expander as a temporary bridge to delayed autologous reconstruction are unknown. Placing prepectoral tissue expanders, without ADM, as a bridge to delayed autologous reconstruction could yield cost savings, shorten operating time and decrease complications.

Hyoid Position and Aging: A Comprehensive Analysis Using AI-assisted Segmentation of 282 Computed Tomography Scans.

Background: With neck, aging the cervicomental angle becomes obtuse and may be influenced by hyoid bone aging. An understanding of hyoid position changes with aging will further our understanding of its role in neck contour changes.

Methods: A 3D volumetric reconstruction of 282 neck computed tomography scans was performed.

Endothelial protein disulfide isomerase A1 enhances membrane stiffness and platelet-endothelium interaction in hyperglycemia via SLC3A2 and LAMC1.

Background: Diabetes carries an increased risk of cardiovascular disease and thromboembolic events. Upon endothelial dysfunction, platelets bind to endothelial cells to precipitate thrombus formation; however, it is unclear which surface proteins regulate platelet-endothelium interaction. We and others have shown that peri/epicellular protein disulfide isomerase A1 (pecPDI) influences the adhesion and migration of vascular cells.

Filarial nematodes in domestic dogs and mosquitoes (Diptera: Culicidae) from semi-rural areas in Central Chile.

Climate change, competent vectors, and reservoir animals are the main factors for developing vector-borne zoonotic diseases. These diseases encompass a significant and widespread category of pathogens (e.g.

Practical management of hypertrophic scarring: the mayo clinic experience.

Hypertrophic scarring is a potential consequence of wound healing that causes functional and aesthetic disability. Common treatments include intralesional pharmacotherapy (e.g.

Lower Extremity Somatosensory Evoked Potentials Predict Functional Outcomes in Complete Traumatic Cervical Spinal Cord Injury.

Background: Traumatic cervical spinal cord injury (tCSCI) is often a debilitating injury, making early prognosis important for medical and surgical planning. Currently, the best early predictors of prognosis are physical examination, imaging studies, and patient demographics. Despite these factors, patient outcomes continue to vary significantly.

Lymphatic Mapping with Contrast-enhanced Ultrasound for Lymphaticovenous Anastomosis Surgery: How We Do It.

Lymphaticovenous anastomosis (LVA) surgery is an effective surgery for the treatment of lymphedema in the extremities. Indocyanine green lymphography is the reference standard for visualizing lymphatics for LVA surgery, but it has several limitations; most notably, superficial dermal congestion can mask deeper lymphatic vessels. To overcome the limitations, we add contrast-enhanced ultrasound (CEUS) lymphography.

Insights from a Computational-Based Approach for Analyzing Autophagy Genes across Human Cancers.

In the last decade, there has been a boost in autophagy reports due to its role in cancer progression and its association with tumor resistance to treatment. Despite this, many questions remain to be elucidated and explored among the different tumors. Here, we used omics-based cancer datasets to identify autophagy genes as prognostic markers in cancer.

Evaluation of Perioperative Versus Extended Courses of Antibiotic Prophylaxis After Immediate Implant-Based Breast Reconstruction.

Background: Immediate implant-based breast reconstruction (IIBR) is the most commonly used method in breast reconstruction in the United States. However, postoperative surgical site infections (SSIs) can cause devastating reconstructive failure. This study evaluates the use of perioperative versus extended courses of antibiotic prophylaxis after IIBR for the prevention of SSI.

Surgical and Patient-Reported Outcomes of Open Perforator-Preserving Anterior Component Separation for Ventral Hernia Repair.

Background:  Abdominal wall reconstruction is challenging for surgeons and may be life altering for patients. There are scant high-quality studies on patient-reported outcomes following abdominal wall reconstruction. We assess long-term surgical and patient-reported outcomes of perforator-preserving open anterior component separation (OPP-ACS) following large ventral hernia repair.

Extracellular Vesicle-Packaged miR-195-5p Sensitizes Melanoma to Targeted Therapy with Kinase Inhibitors.

Management of advanced melanoma remains challenging, with most BRAF (B-Raf proto-oncogene, serine/threonine kinase)-mutated metastatic patients relapsing within a few months upon MAPK inhibitors treatment. Modulation of tumor-derived extracellular vesicle (EVs) cargo with enrichment of antitumoral molecules is a promising strategy to impair tumor progression and increase treatment response. Herein, we report that restored expression of miR-195-5p, down-regulated in melanoma favoring drug resistance, increases the release of EVs enriched in the tumor suppressor miRNAs, miR-195-5p, miR-152-3p, and miR-202-3p.

Humoral and cellular response induced by a second booster of an inactivated SARS-CoV-2 vaccine in adults.

Background: The Omicron variant has challenged the control of the COVID-19 pandemic due to its immuno-evasive properties. The administration of a booster dose of a SARS-CoV-2 vaccine showed positive effects in the immunogenicity against SARS-CoV-2, effect that is even enhanced after the administration of a second booster.

Methods: During a phase-3 clinical trial, we evaluated the effect of a second booster of CoronaVac®, an inactivated vaccine administered 6 months after the first booster, in the neutralization of SARS-CoV-2 (n = 87).

Inhibition of autophagy in microglia and macrophages exacerbates innate immune responses and worsens brain injury outcomes.

Excessive and prolonged neuroinflammation following traumatic brain injury (TBI) contributes to long-term tissue damage and poor functional outcomes. However, the mechanisms contributing to exacerbated inflammatory responses after brain injury remain poorly understood. Our previous work showed that macroautophagy/autophagy flux is inhibited in neurons following TBI in mice and contributes to neuronal cell death.

Who Cares about Diversity? Trends in Gender and Racial Authorship and Publications in Plastic Surgery over Time.

Unlabelled: The literature in scientific journals represents current standards for plastic surgery (PS) and new observations contributed by leaders in the field. Observations of these trends over time define our progress and document our ever-changing specialty. This study aims to assess the racial/ethnic and gender makeup of authors who have published on the topic of diversity in PS, and to define trends over time, as well as geographic and journal representation of these publications.

Large-scale population disappearances and cycling in the white-lipped peccary, a tropical forest mammal.

Many vertebrate species undergo population fluctuations that may be random or regularly cyclic in nature. Vertebrate population cycles in northern latitudes are driven by both endogenous and exogenous factors. Suggested causes of mysterious disappearances documented for populations of the Neotropical, herd-forming, white-lipped peccary (Tayassu pecari, henceforth "WLP") include large-scale movements, overhunting, extreme floods, or disease outbreaks.

MG-: A Novel Galectin-3 Ligand with Antimelanoma Properties and Adjuvant Effects to Dacarbazine.

Melanoma is a highly metastatic and rapidly progressing cancer, a leading cause of mortality among skin cancers. The melanoma microenvironment, formed from the activity of malignant cells on the extracellular matrix and the recruitment of immune cells, plays an active role in the development of drug resistance and tumor recurrence, which are clinical challenges in cancer treatment. These tumoral metabolic processes are affected by proteins, including Galectin-3 (Gal-3), which is extensively involved in cancer development.

Breast Resection Weight Prediction and Insurance Reimbursement in Reduction Mammaplasty: Which Scale Is Reliable?

Background: Many insurance companies in the United States rely on the Schnur sliding scale to predict resection weights to determine medical necessity for breast reduction surgery. Accurate methods to predict resection weights are needed to avoid insurance denials. The authors compared the accuracy of formulas such as the Schnur, Appel, Descamps, and Galveston scales in predicting resection weights, and assessed whether they influence insurance coverage decision.
