BACKGROUND: Lymphedema is an iatrogenic complication after breast cancer treatment in which lymph fluid in the affected limb progresses to fat deposition and fibrosis that are amenable to liposuction treatment. Magnetic resonance imaging (MRI) for lymphedema can differentiate fat tissue from fluid, but estimating relative volumes remains problematic. METHODS AND RESULTS: Patients underwent routine bilateral arm MRI both before and after liposuction for advanced lymphedema...

BACKGROUND: Metabolic syndrome (MetS) identifies subjects with increased risk of cardiovascular disease when they have a combination of insulin resistance, obesity, hypertension, hyperglycemia, low high-density lipoprotein cholesterol (HDL-C), and elevated triglycerides (TGs). Increasing evidence suggests that vitamin D deficiency could be associated with diabetes and MetS. The aim is to assess if 25-hydroxyvitamin D (25-OHD) is correlated with cardiovascular risk components of MetS. METHODS: A cross-sectional study involved 124 diabetic patients with MetS according to International Diabetes Federation definition...

Digital Health Innovations have great potential to improve access to evidence-based psychological therapies. This comprehensive review and meta-analysis sets out the current state of the field including the efficacy of the interventions for different types of mental health problems and the desirability of the interventions from the patients' perspective. It also highlights the poor methodology of much of the research and suggests important ways forward to improve the quality of the data. The importance of assessing and understanding the potential negative impact of such interventions is emphasised both in the review and the commentary, and suggestions are made to maximise the likelihood that such interventions are accessible within routine services...

Bligh and Dyer (B & D) or Folch procedures for the extraction and separation of lipids from microorganisms and biological tissues using chloroform/methanol/water have been used tens of thousands of times and are "gold standards" for the analysis of extracted lipids. Based on the Conductor-like Screening MOdel for realistic Solvatation (COSMO-RS), we select ethanol and ethyl acetate as being potentially suitable for the substitution of methanol and chloroform. We confirm this by performing solid-liquid extraction of yeast (Yarrowia lipolytica IFP29) and subsequent liquid-liquid partition-the two steps of routine extraction...

The aim of this study was to evaluate the histopathologic parameters that predict lymph node metastasis in patients with oral squamous cell carcinoma (OSCC) and to design a new assessment score on the basis of these parameters that could ultimately allow for changes in treatment decisions or aid clinicians in deciding whether there is a need for close follow-up or to perform early lymph node dissection. Histopathologic parameters of 336 cases of OSCC with stage cT1/T2 N0M0 disease were analyzed. The location of the tumor and the type of surgery used for the management of the tumor were recorded for all patients...

Human papillomavirus (HPV) is associated with anogenital cancer (including cervical, vaginal, vulvar, penile, and anal), oropharyngeal cancer, and genital warts. The HPV vaccination significantly reduces the incidence of anogenital cancer and genital warts. Despite the benefits of HPV vaccines, only 41.9% of girls in the recommended age group, and only 28.1% of males in the recommended age group have received all recommended doses. Compared with many other countries, HPV vaccination rates in the United States are unacceptably low...

Melanocytic neoplasms are common in dogs and frequently occur within the oral cavity or in haired skin. The behavior of melanocytic neoplasms is variable and depends on tumor location, size, and histopathologic features. This study compared cytopathology and histopathology of 32 lymph nodes from 27 dogs diagnosed with melanocytic neoplasms. Agreement between the original cytology report, cytology slide review, original histopathology report, and histopathology slide review was determined for each lymph node...

High-throughput screening (HTS) is now routinely conducted for drug discovery by both pharmaceutical companies and screening centers at academic institutions and universities. Rapid advance in assay development, robot automation, and computer technology has led to the generation of terabytes of data in screening laboratories. Despite the technology development toward HTS productivity, fewer efforts were devoted to HTS data integration and sharing. As a result, the huge amount of HTS data was rarely made available to the public...

Neurodegenerative diseases progress slowly, creating increasing physical disability with unpredictable disease trajectories. The disease's life-threatening nature often places these patients in palliative care. There are several factors that complicate the care of patients with neurodegenerative diseases in palliative care units. Owing to physical impairments, there are many communication barriers between patients and staff. Nurses are not able to duplicate the patient's meticulous daily routine leading to caregiver mistrust in the nurse's competencies...

The vibrational frequency of a chosen normal mode is one of the most accurately measurable spectroscopic properties of molecules in condensed phases. Accordingly, infrared absorption and Raman scattering spectroscopy have provided valuable information on both distributions and ensemble-average values of molecular vibrational frequencies, and these frequencies are now routinely used to investigate structure, conformation, and even absolute configuration of chemical and biological molecules of interest. Recent advancements in coherent time-domain nonlinear vibrational spectroscopy have allowed the study of heterogeneous distributions of local structures and thermally driven ultrafast fluctuations of vibrational frequencies...

Total Reflection X-ray Fluorescence (TXRF) is becoming more and more popular for elemental analysis in academia and industry. However, simplification of the procedures for analyzing samples with complex compositions and residual matrix effects is still needed. In this work, the effect of an inorganic (CaCl2) and an organic (tetraalkylphosphonium chloride) matrix on metals quantification by TXRF was investigated for liquid samples. The samples were spiked with up to 20 metals at concentrations ranging from 3 to 50 mg L-1 per element, including elements with spectral peaks near the peaks of the matrix elements or near the Raleigh and Compton scattering peaks of the X-ray source (molybdenum anode)...

BACKGROUND: Ostructive sleep apnea (OSA) is an independent risk factor for the development of cardiovascular events. Platelet activation and inflammation are the mechanisms involved in the association between OSA and cardiovascular disease (CVD). The markers of platelet activation and inflammation are the mean platelet volume (MPV), platelet-lymphocyte ratio (PLR), red cell distribution width (RDW), neutrophil- lymphocyte ratio (NLR). We aimed to define the association of NLR, PLR, RDW, and MPV with the severity of disease and the presence of CVD...
