Health literacy enhancement through food guide and hygiene education: a study among Taiwanese students.

The World Health Organization defined health as 'a condition of full physical, mental and social well-being'. Nutrition and food safety are intertwined and two of the most influential determinants of human health. This study primarily aimed to design and implement a specialized curriculum focused on food hygiene, and Taiwan's daily food guide to enhance health literacy among junior high students in Taiwan.

TGFβ1 induces CXCL1 to promote stemness features in lung cancer.

Chemokines critically orchestrate the tumorigenesis, metastasis, and stemness features of cancer cells that lead to poor outcomes. High plasma levels of transforming growth factor-β1 (TGFβ1) correlate with poor prognostic features in advanced lung cancer patients, thus suggesting the importance of TGFβ1 in the lung tumor microenvironment. However, the role of chemokines in TGFβ1-induced tumor stemness features remains unclear.

Solution-Processable Quinoidal Dithioalkylterthiophene-Based Small Molecules Pseudo-Pentathienoacenes an Intramolecular S···S Lock for High-Performance n-Type Organic Field-Effect Transistors.

A new organic small-molecule family comprising tetracyanoquinodimethane-substituted quinoidal dithioalky(SR)terthiophenes (s) ( (); SR = SCH, (); SR = SCH, (); SR = SCH) was synthesized and contrasted with a nonthioalkylated analogue ( (); R = CH). The physical, electrochemical, and electrical properties of these new compounds are thoroughly investigated. Optimized geometries obtained from density functional theory calculations and single-crystal X-ray diffraction reveal the planarity of the SR-containing core.

Thioalkyl-Functionalized Bithiophene (SBT)-Based Organic Sensitizers for High-Performance Dye-Sensitized Solar Cells.

A series of 3,3'-dithioalkyl-2,2'-bithiophene (SBT)-based organic chromophores were designed and developed for the use in dye-sensitized solar cells (DSSCs). By appropriate structural modification of the SBT π-linkers with different alkyl chains and conjugated thiophene units, chromophore aggregation and interfacial charge recombination could be suppressed to a remarkable degree. Single-crystal and optical/electrochemical data clearly show that the SBT core is nearly planar with the torsional angle <1°, likely via S(alkyl)···S(thiophene) intramolecular locks.

Platinum-based combination chemotherapy triggers cancer cell death through induction of BNIP3 and ROS, but not autophagy.

These days, cancer can still not be effectively cured because cancer cells readily develop resistance to anticancer drugs. Therefore, an effective combination of drugs with different mechanisms to prevent drug resistance has become a very important issue. Furthermore, the BH3-only protein BNIP3 is involved in both apoptotic and autophagic cell death.

Disco spotlight sign: A sign that may be useful for diagnosis of pneumomediastinum.

The use of ultrasonography for the investigation of pneumomediastinum is limited by the presence of air artifacts. Air accumulation in the mediastinum obscures the heart, sometimes leading to misinterpretation as lung tissue. We found that cardiac apical swinging during the heart cycle, however, can create a uniquely characteristic squeezing of mediastinal free air, producing a sonographic B-line that flashes in and out.

TNF-α augments CXCR2 and CXCR3 to promote progression of renal cell carcinoma.

Within the tumour microenvironment, a complex network of chemokines and their receptors affects the initiation and progression of tumours. The higher levels of tumour necrosis factor-alpha (TNF-α) are associated with tumour progression and an anti-TNF-α monoclonal antibody has been used successfully to treat patients with renal cell carcinoma (RCC). However, the role of chemokines and their receptors in the TNF-α-promoted progression of RCC remains unclear.

Superior upconversion fluorescence dopants for highly efficient deep-blue electroluminescent devices.

In this study, we revealed a new approach for the development of new triplet-triplet annihilation (TTA) materials with highly efficient deep-blue fluorescence the incorporation of a styrylpyrene core and an electron-donating group. The resulting deep-blue emitters (PCzSP, DFASP, and DPASP) exhibit intramolecular charge transfer emissions with remarkably high emission quantum yields. The electroluminescent devices based on these three fluorophores as dopants using CBP as a host exhibit very high device efficiencies; in particular, the DPASP-doped device reveals an extremely high EQE of 12%, reaching the limit of a TTA-based device.

Galectin-3 augments tumor initiating property and tumorigenicity of lung cancer through interaction with β-catenin.

Cancer stem cells (CSCs) are comprised of a rare sub-population of cells in tumors that have been proposed to be responsible for high recurrence rates and resistance to chemotherapy. Galectins are highly expressed in cancers that correlate with the aggressiveness of tumors. Galectins may also promote the resistance of cancer cells to chemotherapy.

Shrinkage regression-based methods for microarray missing value imputation.

Background: Missing values commonly occur in the microarray data, which usually contain more than 5% missing values with up to 90% of genes affected. Inaccurate missing value estimation results in reducing the power of downstream microarray data analyses. Many types of methods have been developed to estimate missing values.

Reliability and validity of outcome measures of in-hospital and at-home visits in a randomized, double-blind, placebo-controlled trial for spinal muscular atrophy.

We used at-home assessments in a clinical trial to relieve the visit burden for participants. A total of 57 patients with type II or III spinal muscular atrophy were enrolled and 10 of them (7 type II and 3 type III) received at-home assessments. The primary end points were Gross Motor Function Measure, Manual Muscle Test, and serum biomarker.

Awareness of HIV/AIDS prevention and acceptance of HIV testing among residents in Likoma Island, northern Malawi.

To evaluate the awareness of HIV/AIDS prevention education, and the acceptance of HIV testing among residents on Likoma Island, Malawi, a cross-sectional, population-based study of 579 residents aged > or =15 years from seven villages on Likoma Island was conducted during July and August 2007. Most of the subjects studied could correctly answer questions about their awareness of AIDS and knowledge of the ways to reduce HIV transmission. Moreover, the proportion of respondents (65.

Insights into the conformational changes of several human lysozyme variants associated with hereditary systemic amyloidosis.

In this study, various ethanol- and temperature-induced molecular dynamics simulations were conducted to investigate the conformational changes of several human lysozyme variants (I56T, D67H, and T70N) associated with hereditary systemic amyloidosis. The results show that these variants are all more sensitive to conditions affecting the structural integrity of this protein. The structural analyses of these variants reveal a high population of more unstable beta-domain and distorted hydrophobic core compared to the wild-type human lysozyme, particularly for the two natural amyloidogenic variants D67H and I56T.

Structural analysis of human lysozyme using molecular dynamics simulations.

In this study, various molecular dynamics simulations were conducted to investigate the effects of ethanol and temperature on the conformational changes of human lysozyme, which may lead insights into amyloidosis. The analyses of some important structural characteristics, such as backbone root-mean-square deviation, secondary structural stability, radius of gyration, accessible surface area, and hydrophobic contact of the hydrophobic core all show that ethanol tends to destabilize human lysozyme at high temperatures. It can be attributed to that higher temperatures result in the destruction of the native structure of this protein, leading to the exposure of the interior hydrophobic core.
