Accelerated Discovery of Solvation Structure Engineering for Stable Aqueous Rechargeable Zinc Batteries via Physics-Guided Bayesian Active Learning.

Aqueous rechargeable zinc batteries, despite advantages like safety and performance, struggle with water-based side reactions such as hydrogen evolution and corrosion. Regulating the solvation structure of Zn is essential for stability. Introducing n-hexane, a nonpolar alkane, modifies Zn coordination and stabilizes the Zn anode-electrolyte interface.

Sensory Stimuli to Sustainable Social Wellbeing: A Multimodal Approach Based on Warm Scent.

Sensory experiences affect individuals' judgment and behavior through the metaphors that experiences carry. The literature has demonstrated that the perception of warmth activates concepts related to positive meaning and metaphors, such as consideration and gentleness, which increase individuals' tendency to help or relate to others. This study hypothesized that warm olfactory stimuli influence intention toward prosocial behavior by increasing the need for social connectedness (NSC).

Identification of Speech Characteristics to Distinguish Human Personality of Introversive and Extroversive Male Groups.

According to the similarity-attraction theory, humans respond more positively to people who are similar in personality. This observation also holds true between humans and robots, as shown by recent studies that examined human-robot interactions. Thus, it would be conducive for robots to be able to capture the user personality and adjust the interactional patterns accordingly.

Synthesis, Structure Revision, and Cytotoxicity of Nocarbenzoxazole G.

The total synthesis of nocarbenzoxazoles F (1) and G (2), originally obtained from the marine-derived halophilic bacterial strain Nocardiopsis lucentensis DSM 44048, was achieved via a simple and versatile route involving microwave-assisted construction of a benzoxazole skeleton, followed by carbon-carbon bond formation with the corresponding aryl bromides. Unfortunately, the H and C NMR spectra of natural nocarbenzoxazole G did not agree with those of the synthesized compound. In particular, the spectra of the isolated and synthesized compounds showed considerable differences in the signals from the protons and carbons in the aryl group.

Predictors of postoperative eGFR change and resolution of hyperfiltration in obese patients following bariatric surgery.

Background: Bariatric surgery (BS) can improve glomerular hyperfiltration (GHPF). Very few studies identified associative factors with glomerular filtration rate and resolution from GHPF after BS.

Objectives: To investigate the predictors of estimated GFR (eGFR) changes and resolution from GHPF after BS.

Rigidity of silicone substrates controls cell spreading and stem cell differentiation.

The dependences of spreading and differentiation of stem cells plated on hydrogel and silicone gel substrates on the rigidity and porosity of the substrates have recently been a subject of some controversy. In experiments on human mesenchymal stem cells plated on soft, medium rigidity, and hard silicone gels we show that harder gels are more osteogenic, softer gels are more adipogenic, and cell spreading areas increase with the silicone gel substrate rigidity. The results of our study indicate that substrate rigidity induces some universal cellular responses independently of the porosity or topography of the substrate.

Correlation between Semi-Quantitative (18)F-FDG PET/CT Parameters and Ki-67 Expression in Small Cell Lung Cancer.

Purpose: The aim of this study was to evaluate the relationship between semiquantitative parameters on (18)F-FDG PET/CT including maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) and the expression level of Ki-67 in small-cell lung cancer (SCLC).

Methods: Ninety-four consecutive patients with SCLC were enrolled in this study. They underwent (18)F-FDG PET/CT for initial evaluation of SCLC, and we measured SUVmax, avgSUVmean, MTVsum, and TLGtotal on (18)F-FDG PET/CT images.

Concurrent Carotid Inflammation in Acute Coronary Syndrome as Assessed by (18)F-FDG PET/CT: A Possible Mechanistic Link for Ischemic Stroke.

Background: Patients with acute coronary syndrome (ACS) are prone to ischemic stroke (IS) especially during the early phase. ACS patients are more likely to have concurrent complex carotid plaques which, when destabilized, may serve as a source of distal embolism. This study investigated whether inflammatory activity in carotid artery was increased in ACS survivors compared to chronic stable angina (CSA) patients.

Value of (18)F-FDG PET/CT in the Detection of Ovarian Malignancy.

Purpose: Ovarian cancer is a leading cause of gynecologic malignancy. As symptoms of ovarian cancer are nonspecific, only 20 % of ovarian cancers are diagnosed while they are still limited to the ovaries. Thus, early and accurate detection of disease is important for an improved prognosis.

CD98hc (SLC3A2) loss protects against ras-driven tumorigenesis by modulating integrin-mediated mechanotransduction.

CD98hc (SLC3A2) is the heavy chain component of the dimeric transmembrane glycoprotein CD98, which comprises the large neutral amino acid transporter LAT1 (SLC7A5) in cells. Overexpression of CD98hc occurs widely in cancer cells and is associated with poor prognosis clinically, but its exact contributions to tumorigenesis are uncertain. In this study, we showed that genetic deficiency of CD98hc protects against Ras-driven skin carcinogenesis.

The role of interim 18F-FDG PET/CT in predicting early response to neoadjuvant chemotherapy in breast cancer.

Aim: The aim of this study was to prove the diagnostic value of interim 18F-Fluorodeoxyglucose-positron-emission tomography combined with computed tomography (PET/CT) scan for predicting pathological complete response (pCR) compared to other factors in neoadjuvant chemotherapy.

Patients And Methods: Twenty-seven patients with breast cancer were included in this retrospective study. They all underwent scheduled neoadjuvant chemotherapy.

The Clinical Role of Dual-Time-Point (18)F-FDG PET/CT in Differential Diagnosis of the Thyroid Incidentaloma.

Thyroid incidentalomas are common findings during imaging studies including (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) for cancer evaluation. Although the overall incidence of incidental thyroid uptake detected on PET imaging is low, clinical attention should be warranted owing to the high incidence of harboring primary thyroid malignancy. We retrospectively reviewed 2,368 dual-time-point (18)F-FDG PET/CT cases that were undertaken for cancer evaluation from November 2007 to February 2009, to determine the clinical impact of dual-time-point imaging in the differential diagnosis of thyroid incidentalomas.

Expression patterns of glucose transporter-1 gene and thyroid specific genes in human papillary thyroid carcinoma.

Purpose: The expression of glucose transporter-1 (Glut-1) gene and those of major thyroid-specific genes were examined in papillary carcinoma tissues, and the expressions of these genes were compared with cancer differentiation grades.

Materials And Methods: Twenty-four human papillary carcinoma tissues were included in this study. The expressions of Glut-1- and thyroid-specific genes [sodium/iodide symporter (NIS), thyroid peroxidase, thyroglobulin, TSH receptor and pendrin] were analyzed by RT-PCR.

Prognostic impact of minimal pleural effusion in non-small-cell lung cancer.

Purpose: Minimal (< 10 mm thick) pleural effusion (PE) may represent an early phase of malignant PE, but its clinical relevance has rarely been studied. Therefore, we examined the proportion of minimal PE in patients with non-small-cell lung cancer (NSCLC) and its impact on survival. We also considered possible accumulation mechanisms in our data set.

Data sharing for public health research: A qualitative study of industry and academia.

Data sharing is a key biomedical research theme for the 21st century. Biomedical data sharing is the exchange of data among (non)affiliated parties under mutually agreeable terms to promote scientific advancement and the development of safe and effective medical products. Wide sharing of research data is important for scientific discovery, medical product development, and public health.

Tetraspan TM4SF5-dependent direct activation of FAK and metastatic potential of hepatocarcinoma cells.

Transmembrane 4 L six family member 5 (TM4SF5) plays an important role in cell migration, and focal adhesion kinase (FAK) activity is essential for homeostatic and pathological migration of adherent cells. However, it is unclear how TM4SF5 signaling mediates the activation of cellular migration machinery, and how FAK is activated during cell adhesion. Here, we showed that direct and adhesion-dependent binding of TM4SF5 to FAK causes a structural alteration that may release the inhibitory intramolecular interaction in FAK.

Peripheral bone involvement of intravascular large B-cell lymphoma on 99mTc-MDP bone scan and 18F-FDG PET/CT.

A 64-year-old man was admitted for evaluation of recently developed anemia and bone pain. The bone scan showed diffusely active lesions in the peripheral bones, symmetrically. Interestingly, 18F-FDG PET/CT revealed the hypermetabolic changes in the peripheral bones as well as the internal organs.

Cross-talk between TGFβ1 and EGFR signalling pathways induces TM4SF5 expression and epithelial-mesenchymal transition.

The EMT (epithelial-mesenchymal transition) is involved in fibrosis and cancer, and is regulated by different signalling pathways mediated through soluble factors, actin reorganization and transcription factor actions. Because the tetraspan (also called tetraspanin) TM4SF5 (transmembrane 4 L6 family member 5) is highly expressed in hepatocellular carcinoma and induces EMT, understanding how TM4SF5 expression in hepatocytes is regulated is important. We explored the mechanisms that induce TM4SF5 expression and whether impaired signalling pathways for TM4SF5 expression inhibit the acquisition of mesenchymal cell features, using human and mouse normal hepatocytes.

Sulfur mustard primes human neutrophils for increased degranulation and stimulates cytokine release via TRPM2/p38 MAPK signaling.

Sulfur mustard (2,2'-bis-chloroethyl-sulfide; SM) has been a military threat since the World War I. The emerging threat of bioterrorism makes SM a major threat not only to military but also to civilian world. SM injury elicits an inflammatory response characterized by infiltration of neutrophils.

Proteasome inhibition causes epithelial-mesenchymal transition upon TM4SF5 expression.

Transmembrane 4 L six family member 5 (TM4SF5) is highly expressed in hepatocarcinoma and causes epithelial-mesenchymal transition (EMT) of hepatocytes. We found that TM4SF5-expressing cells showed lower mRNA levels but maintained normal protein levels in certain gene cases, indicating that TM4SF5 mediates stabilization of proteins. In this study, we explored whether regulation of proteasome activity and TM4SF5 expression led to EMT.

Modulation of signaling between TM4SF5 and integrins in tumor microenvironment.

TM4SF5 is a transmembrane glycoprotein of the transmembrane 4 L six family, a branch of the tetraspanin family and highly expressed in many types of cancers. TM4SF5 induces epithelial-mesenchymal transition (EMT) by morphological changes resulting from inactivation of RhoA mediated by stabilized cytosolic p27kip1. TM4SF5-mediated EMT can lead to loss of contact inhibition and enhanced migration/invasion, presumably depending on cross-talks between TM4SF5 and integrins.

Radiation safety issues in y-90 microsphere selective hepatic radioembolization therapy: possible radiation exposure from the patients.

Purpose: The purpose of this study was to estimate the possible external radiation dose to other individuals from patients treated with Y-90 resin microspheres for unresectable hepatocellular carcinoma.

Methods: We designed the study prospectively to estimate the possible radiation dose to other individuals from patients who had been treated with Y-90 microspheres for unresectable hepatocellular carcinoma. We estimated the total effective dose equivalent (TEDE) using two methods: 'theoretical' TEDEs according to the administered activity and 'measured' TEDE based on the 'measured' ambient radiation exposure rate.

Differential inhibition of transmembrane 4 L six family member 5 (TM4SF5)-mediated tumorigenesis by TSAHC and sorafenib.

Two separate clinical studies of advanced hepatocarcinoma patients recently reported that the multikinase inhibitor sorafenib (nexavar) could extend survival of the patients only by 2-3 months. We also previously demonstrated that 4'-(p-toluenesulfonylamido)-4-hydroxychalcone (TSAHC) blocks the multilayer growth and migration mediated by TM4SF5, which is highly expressed in approximately 80% of Korean hepatocarcinoma patients. Therefore, we wondered how TSAHC might be different from sorafenib to deal with hepatocarcinoma in terms of the therapeutic characteristics including specificity for TM4SF5.
