Too little or too much: nonlinear relationship between sleep duration and daily affective well-being in depressed adults.

Background: In addition to having higher negative affect and lower positive affect overall, depressed individuals exhibit heightened affective reactivity to external stimuli than non-depressed individuals. Sleep may contribute to day-to-day fluctuations in depressed individuals, given that sleep disturbance is a common symptom of depression. Yet, little is known about changes in daily affect as a function of nightly sleep duration in depressed adults and non-depressed adults.

Biophysical interplay between extracellular matrix remodeling and hypoxia signaling in regulating cancer metastasis.

Mechanical properties of the tumor microenvironment play a critical role in cancer progression by activation of cancer mechano-responses. The biophysical interactions between cancer cells and their dynamic microenvironment are attributed to force-dependent alterations in molecular pathways that trigger the structural reorganization of intracellular organelles and their associated genetic modifications. Recent studies underscore the role of oxygen concentration in cancer metastasis.

Daily Affective Dynamics in Major Depressive Disorder: The Role of Daily Stressors and Positive Events.

This study examined daily affective dynamic indices among individuals with a major depressive disorder (MDD) diagnosis in the past one year at the time of the interview, focusing on affective variability and change in affect in response to daily events (affective reactivity). Data were from the main survey and daily diary project of the Midlife in the United States (MIDUS) study. Participants ( = 1,970;  = 202;  = 1,768) completed structured clinical interviews on mental health and telephone interviews about their daily experiences spanning eight consecutive days.

Affective reactivity to daily stressors and immune cell gene expression in the MIDUS study.

Affective reactivity to stress is a person-level measurement of how well an individual copes with daily stressors. A common method of measuring affective reactivity entails the estimation of within-person differences of either positive or negative affect on days with and without stressors present. Individuals more reactive to common stressors, as evidenced by affective reactivity measurements, have been shown to have increased levels of circulating pro-inflammatory markers.

Treatment decision for cancer patients with fever during the coronavirus disease 2019 (COVID-19) pandemic.

Backgruound: Cancer patients have been disproportionally affected by the coronavirus disease 2019 (COVID-19) pandemic, with high rates of severe outcomes and mortality. Fever is the most common symptom in COVID-19 patients. During the COVID-19 pandemic, physicians may have difficulty in determining the cause of fever (COVID-19, another infection, or cancer fever) in cancer patients.

Interobserver Reproducibility in Sonographic Measurement of Diameter and Volume of Papillary Thyroid Microcarcinoma.

Active surveillance is recommended as an alternative to immediate surgery for low-risk papillary thyroid microcarcinoma (PTMC), and determining meaningful changes in diameter and volume on ultrasonography (US) is critical. However, interobserver reproducibility of the sonographic measurement of maximum diameter and volume of PTMC has not been well established. We aimed to determine the reproducibility in the measurement of maximum diameter and volume of PTMC on US.

Molecular diagnosis of hereditary spherocytosis by multi-gene target sequencing in Korea: matching with osmotic fragility test and presence of spherocyte.

Background: Current diagnostic tests for hereditary spherocytosis (HS) focus on the detection of hemolysis or indirectly assessing defects of membrane protein, whereas direct methods to detect protein defects are complicated and difficult to implement. In the present study, we investigated the patterns of genetic variation associated with HS among patients clinically diagnosed with HS.

Methods: Multi-gene targeted sequencing of 43 genes (17 RBC membrane protein-encoding genes, 20 RBC enzyme-encoding genes, and six additional genes for the differential diagnosis) was performed using the Illumina HiSeq platform.

Comparison of three risk stratification models for non-clear cell renal cell carcinoma patients treated with temsirolimus as first-line therapy.

Background/aims: For metastatic renal cell carcinoma (RCC), various prognostic scoring systems have been developed. However, owing to the low prevalence of nonclear cell RCC, the three most commonly used tools were mainly developed based on patients with clear cell histology. Accordingly, this study applied three prognostic models to Korean non-clear cell RCC patients treated with first-line temsirolimus.

An Open-Label, Randomized, Parallel, Phase III Trial Evaluating the Efficacy and Safety of Polymeric Micelle-Formulated Paclitaxel Compared to Conventional Cremophor EL-Based Paclitaxel for Recurrent or Metastatic HER2-Negative Breast Cancer.

Purpose: Genexol-PM is a Cremophor EL-free formulation of low-molecular-weight, non-toxic, and biodegradable polymeric micelle-bound paclitaxel. We conducted a phase III study comparing the clinical efficacy and toxicity of Genexol-PM with conventional paclitaxel (Genexol).

Materials And Methods: Patients were randomly assigned (1:1) to receive Genexol-PM 260 mg/m or Genexol 175 mg/m intravenously every 3 weeks.

Application of mutant JAK2V617F for in vitro generation of red blood cells.

Background: In vitro generation of red blood cells (RBCs) from hematopoietic stem cells (HSCs) has been reported, but the collection of 1 × 10(5) to 1 × 10(6) CD34+ cells present in cord and peripheral blood is too small for expansion to 1 × 10(12) cells in 1 unit of RBCs. We transduced JAK2V617F gene, the most common mutation with polycythemia vera (PV), into cord blood-derived CD34+ cells. This PV model was expected to increase cell proliferation without the addition of erythropoietin (EPO) in early phase of differentiation.

The purpose of the present study was to compare diagnostic performances of FANA and line immune assay (LIA) detecting 15 sp-ANAs in patients with systemic rheumatic diseases (SRD). In 948 sera from the patients with SRD (n = 590) and non-SRD (n = 358), we evaluated the fluorescent patterns and intensities in the FANA test, and compared the FANA results with sp-ANAs against nRNP, Sm, SS-A, Ro52, SS-B, Scl-70, PM/Scl, Jo-1, CENP B, PCNA, dsDNA, nucleosome, histone, ribosomal-P, and M2.

A facile synthesis of highly functionalized 4-arylcoumarins via Kostanecki reactions mediated by DBU.

An efficient synthesis of 4-arylcoumarins has been accomplished via Kostanecki reactions of 2-hydroxybenzophenones with acetic anhydride employing DBU at ambient temperature. Using the same strategy, several 2-acyloxybenzophenone derivatives were readily converted to 3,4-difunctionalized coumarins. This protocol offers a notable improvement in reaction conditions for coumarin synthesis and takes advantage of its synthetic capability, especially for highly functionalized 4-arylcoumarins with structural diversity.
