Expression of HSP70 in Human Skin After Cryolipolysis Treatment.

Background: Cryolipolysis nonsurgically targets and reduces subcutaneous fat through controlled cooling of skin and underlying fatty tissue. Although skin changes after cryolipolysis treatment have been observed clinically, the mechanisms by which these occur are not well understood.

Objectives: The aim of this study was to investigate the expression of heat shock protein 70 (HSP70) in the epidermal and dermal layers of human skin following cryolipolysis treatment.

Post-Mortem CT Delivers Fast and Accurate Injury Identification in Trauma Patients.

Background: Accurate and timely injury identification is critical but difficult to achieve in trauma patients who die shortly after arrival to the hospital. Autopsy has historically been used to detect injuries, but few undergo formal autopsy. This study investigates the utility of post-mortem computed tomography (PMCT) for injury identification in a diverse trauma population.

Molecular and Histological Evidence Detailing Clinically Observed Skin Improvement Following Cryolipolysis.

Background: In addition to body contouring, there is anecdotal and clinical evidence of reduced laxity caused by skin tightening after cryolipolysis. However, it has not been established how cryolipolysis triggers dermal changes.

Objectives: The aim of this study was to investigate the fundamental mechanisms behind clinically observed dermal changes by molecular and immunohistochemistry (IHC) analytical methods.

Feasibility Study of Electromagnetic Muscle Stimulation and Cryolipolysis for Abdominal Contouring.

Background: In addition to reducing subcutaneous fat for body contouring, some patients are interested in toning the underlying muscle layer.

Objective: This feasibility study evaluated the safety and efficacy of electromagnetic muscle stimulation (EMMS) alone, cryolipolysis alone, and cryolipolysis with EMMS for noninvasive contouring of abdomen.

Methods: Abdomens of 50 subjects were treated in a study with 3 cohorts: EMMS alone, Cryolipolysis alone, and Cryolipolysis + EMMS in combination.

Clinical Study Demonstrates that Electromagnetic Muscle Stimulation Does Not Cause Injury to Fat Cells.

Background And Objectives: A previous pre-clinical study on electromagnetic muscle stimulation (EMMS) suggested that fat cell apoptosis occurs following treatment in a porcine model. While EMMS can induce changes in muscle, the effect on fat tissue is not established. This clinical study sought to assess adipose tissue response to EMMS in comparison to cryolipolysis treatment.

Severe bleeding from a duodenal ulcer after orthognathic surgery: a case report.

Chronic non-steroidal anti-inflammatory drug use is strongly associated with peptic ulcer disease, and corticosteroid use has also been cited as a risk factor. Both are frequently prescribed for short courses after orthognathic surgery to minimize edema. It appears that no cases of severe bleeding from a duodenal ulcer have been reported during the postoperative period after orthognathic surgery.

Delta-S-Cys-Albumin: A Lab Test that Quantifies Cumulative Exposure of Archived Human Blood Plasma and Serum Samples to Thawed Conditions.

Exposure of blood plasma/serum (P/S) to thawed conditions (> -30 °C) can produce biomolecular changes that skew measurements of biomarkers within archived patient samples, potentially rendering them unfit for molecular analysis. Because freeze-thaw histories are often poorly documented, objective methods for assessing molecular fitness before analysis are needed. We report a 10-μl, dilute-and-shoot, intact-protein mass spectrometric assay of albumin proteoforms called "ΔS-Cys-Albumin" that quantifies cumulative exposure of archived P/S samples to thawed conditions.

Bone Mineral Density Among Men and Women Aged 35 to 50 Years.

Context: Osteoporosis is characterized by low bone mineral density (BMD) and has been thought to only be a major health concern for postmenopausal women. However, osteoporosis and its risk factors have been greatly understudied in the middle-aged and male populations.

Objective: To assess the likelihood of low BMD and its association with related risk factors in early-middle-aged (defined in this study as 35-50 years) men and women.

Avelumab: A Novel Anti-PD-L1 Agent in the Treatment of Merkel Cell Carcinoma and Urothelial Cell Carcinoma.

Long-term treatment in the setting of metastatic Merkel cell carcinoma (MCC) and urothelial carcinoma (UC) has shown that current first-line chemotherapeutic agents are losing effectiveness and that there are limited treatment options available outside of radiation therapy and surgical interventions. The use of immunotherapeutic agents such as monoclonal antibodies has been considered a promising alternative for cancers that progress despite treatment with radiation therapy, surgery, and/or chemotherapeutic agents. Cancer cells escape immune surveillance by interrupting immune checkpoint pathways, resulting in dysregulation of T-cell function and so preventing its antitumor effects.

Skin Cancer Knowledge, Attitudes, and Practices among Chinese Population: A Narrative Review.

Skin cancers are becoming a substantial public health problem in China. Fair skin and increased exposure to ultraviolet B (UVB) rays from the sun are among the most substantial risk factors for skin cancer development, thus making the Chinese people vulnerable to this group of diseases. The purpose of this article is to present a narrative review of the knowledge, attitudes, and practices (KAP) related to skin cancers within the Chinese population.

Fabric-based alkaline direct formate microfluidic fuel cells.

Fabric-based microfluidic fuel cells (MFCs) serve as a novel, cost-efficient alternative to traditional FCs and batteries, since fluids naturally travel across fabric via capillary action, eliminating the need for an external pump and lowering production and operation costs. Building on previous research with Y-shaped paper-based MFCs, fabric-based MFCs mitigate fragility and durability issues caused by long periods of fuel immersion. In this study, we describe a microfluidic fabric-based direct formate fuel cell, with 5 M potassium formate and 30% hydrogen peroxide as the anode fuel and cathode oxidant, respectively.

Caregivers of Patients With Left Ventricular Assist Devices: Possible Impacts on Patients' Mortality and Interagency Registry for Mechanically Assisted Circulatory Support-Defined Morbidity Events.

Background: How caregivers contribute to positive or negative outcomes for left ventricular assist device (LVAD) patients remains unclear. Our primary study objectives were to (1) identify caregiver support attributes through a retrospective chart review of social workers' psychosocial assessments for LVAD patients and (2) determine how these attributes associated with patients' post-LVAD placement mortality and Interagency Registry for Mechanically Assisted Circulatory Support-defined morbidity events.

Methods And Results: We retrospectively reviewed and recorded social workers' clinical assessments of adult patients implanted with durable continuous-flow LVADs as bridge to transplant, destination therapy, or bridge to decision from January 2010 to December 2014.

An improved alkaline direct formate paper microfluidic fuel cell.

Paper-based microfluidic fuel cells (MFCs) are a potential replacement for traditional FCs and batteries due to their low cost, portability, and simplicity to operate. In MFCs, separate solutions of fuel and oxidant migrate through paper due to capillary action and laminar flow and, upon contact with each other and catalyst, produce electricity. In the present work, we describe an improved microfluidic paper-based direct formate FC (DFFC) employing formate and hydrogen peroxide as the anode fuel and cathode oxidant, respectively.

Barriers and Facilitators to Initiating and Completing Time-Limited Trials in Critical Care.

Objectives: A time-limited trial is an agreement between clinicians and patients or surrogate decision makers to use medical therapies over a defined period of time to see if the patient improves or deteriorates according to agreed-upon clinical milestones. Although time-limited trials are broadly advocated, there is little empirical evidence of the benefits and risks of time-limited trials, when they are initiated, when and why they succeed or fail, and what facilitates completion of them. Our study objectives were to 1) identify the purposes for which clinicians use time-limited trials and 2) identify barriers and facilitators to initiating and completing time-limited trials.

A microfluidic direct formate fuel cell on paper.

We describe the first direct formate fuel cell on a paper microfluidic platform. In traditional membrane-less microfluidic fuel cells (MFCs), external pumping consumes power produced by the fuel cell in order to maintain co-laminar flow of the anode stream and oxidant stream to prevent mixing. However, in paper microfluidics, capillary action drives flow while minimizing stream mixing.

Ventricular assist devices: a review of psychosocial risk factors and their impact on outcomes.

Background: Psychosocial contraindications for ventricular assist devices (VADs) remain particularly nebulous and are driven by institution-specific practices. Our multi-institutional, multidisciplinary workgroup conducted a review with the goal of addressing the following research question: How are preoperative psychosocial domains predictive of or associated with postoperative VAD-related outcomes? Answers to this question could contribute to the development of treatment-specific (contra) indications for patients under consideration for mechanical devices.

Methods And Results: We identified 5 studies that examined psychosocial factors and their relationship to postoperative VAD-related outcomes.

Contextual effect of repression of bone morphogenetic protein activity in prostate cancer.

Several studies have focused on the effect of bone morphogenetic protein (BMP) on prostate cancer homing and growth at distant metastatic sites, but very little effect at the primary site. Here, we used two cell lines, one (E8) isolated from a primary tumor and the other (cE1) from a recurrent tumor arising at the primary site, both from the conditional Pten deletion mouse model of prostatic adenocarcinoma. Over-expression of the BMP antagonist noggin inhibited proliferation of cE1 cells in vitro while enhancing their ability to migrate.

Knocking out multigene redundancies via cycles of sexual assortment and fluorescence selection.

Phenotypes that might otherwise reveal a gene's function can be obscured by genes with overlapping function. This phenomenon is best known within gene families, in which an important shared function may only be revealed by mutating all family members. Here we describe the 'green monster' technology that enables precise deletion of many genes.

Trends in alcohol use among Hawai'i adolescents.

It is important to review trends in youth alcohol use over time in order to effectively tailor prevention programs to address those trends. This article reviews data on alcohol use behaviors from the Centers for Disease Control and Prevention's Youth Risk Behavior Survey in Hawai'i from 1993 to 2007. Five alcohol use indicators were examined and stratified by grade level, from 9th grade through 12th grade.

Physicians' approaches to recommending colorectal cancer screening: a qualitative study.

Little is known about strategies that physicians use to encourage receipt of colorectal cancer screening (CRCS). This study conducted focus groups with physicians. Twenty-seven physicians participated in four focus groups.

A novel bone morphogenetic protein signaling in heterotypic cell interactions in prostate cancer.

We examined the effect of the extracellular bone morphogenetic protein (BMP) 2 and 7, which are up-regulated in the prostate adenocarcinomas of the conditional Pten deletion mouse model, on primary cultures of cancer-associated fibroblasts (CAF) derived from these tumors. In the CAF, we show that BMP2 or BMP7, but not transforming growth factor beta-1, can strikingly stimulate secretion of stromal cell-derived factor-1 (SDF-1), also known as CXCL12. The CAF cells express type I and type II BMP receptors as well as the receptor for SDF-1, CXCR4.

Bone morphogenetic protein 7 protects prostate cancer cells from stress-induced apoptosis via both Smad and c-Jun NH2-terminal kinase pathways.

We reported earlier that exposure to exogenous bone morphogenetic protein 7 (BMP7) could strongly inhibit serum starvation-induced apoptosis to C4-2B cell line, a variant of the LNCaP human prostate cancer cell line with propensity for bone metastasis. Whereas serum starvation suppressed the expression of survivin, a member of the inhibitor of apoptosis protein family, its expression was sustained in the presence of BMP7. In this study, we present evidence that BMP7 exposure up-regulated survivin promoter activity, an effect that was associated with activation of Smad, and could be repressed by dominant-negative Smad5.

Type I shorthorn sculpin antifreeze protein: recombinant synthesis, solution conformation, and ice growth inhibition studies.

A number of structurally diverse classes of "antifreeze" proteins that allow fish to survive in sub-zero ice-laden waters have been isolated from the blood plasma of cold water teleosts. However, despite receiving a great deal of attention, the one or more mechanisms through which these proteins act are not fully understood. In this report we have synthesized a type I antifreeze polypeptide (AFP) from the shorthorn sculpin Myoxocephalus scorpius using recombinant methods.
