Tumor Location Is an Independent Prognostic Factor in Completely Resected Pathological Stage I Non-Small Cell Lung Cancer: A Multicenter Retrospective Study.

Previous studies suggested that the location of the primary tumor in non-small cell lung cancer (NSCLC) is associated with clinical features and prognosis, but results are conflicting. The purpose of this study was to explore tumor location as an independent risk factor of survival for patients with completely resected pathological stage I NSCLC. This was a multicenter retrospective study conducted in Taiwan.

Role of Peritoneal Equilibration Test in Assessing Folate Transport During Peritoneal Dialysis.

Objectives: Low plasma folate levels have been reported in patients undergoing hemodialysis and peritoneal dialysis (PD) in clinical studies. However, folate transport has never been mentioned as a factor contributing to low plasma folate levels in patients undergoing PD. The peritoneal equilibrium test (PET) assesses the plasma creatinine level and glucose transport abilities.

Comparison of Clinical Outcomes Among Different Fixed-Dose Combinations of Long-Acting Muscarinic Antagonists and Long-Acting β-Agonists in Patients With COPD.

Background: Researchers have yet to obtain conclusive evidence differentiating among fixed-dose combinations (FDCs) of long-acting muscarinic antagonists (LAMAs) and long-acting β-agonists (LABAs) for COPD in terms of real-world clinical outcomes.

Research Question: What are the differences between available LAMA/LABA FDCs in the risk of acute exacerbation (AE) and cardiovascular events?

Study Design And Methods: This retrospective cohort study based on a national insurance claims database included patients with COPD ≥ 40 years of age who were newly prescribed glycopyrronium (GLY)/indacaterol (IND), umeclidinium (UMEC)/vilanterol (VI), or tiotropium (TIO)/olodaterol (OLO) FDC between January 1, 2015, and June 30, 2019. Propensity score matching and Cox regression models were used to compare outcomes of AE and cardiovascular events associated with LAMA/LABA FDC treatment.

The Effects of High-Intensity Power Training versus Traditional Resistance Training on Exercise Performance.

Background: High-intensity interval training (HIIT) features short, repeated bursts of relatively vigorous exercise with intermittent periods of rest or low-intensity exercise. High-intensity power training (HIPT), in combination with HIIT and traditional resistance training (TRT), is characterized as multijoint high-intensity resistance exercises with low interset rest periods. HIPT requires people to finish the exercise as fast as possible, which increases acute physiological demands.

Combination of Mesenchymal Stem Cell-Delivered Oncolytic Virus with Prodrug Activation Increases Efficacy and Safety of Colorectal Cancer Therapy.

Although oncolytic viruses are currently being evaluated for cancer treatment in clinical trials, systemic administration is hindered by many factors that prevent them from reaching the tumor cells. When administered systemically, mesenchymal stem cells (MSCs) target tumors, and therefore constitute good cell carriers for oncolytic viruses. MSCs were primed with trichostatin A under hypoxia, which upregulated the expression of CXCR4, a chemokine receptor involved in tumor tropism, and coxsackievirus and adenovirus receptor that plays an important role in adenoviral infection.

New International Association for the Study of Lung Cancer (IASLC) Pathology Committee Grading System for the Prognostic Outcome of Advanced Lung Adenocarcinoma.

The impact of the new International Association for the Study of Lung Cancer pathology committee grading system for advanced lung adenocarcinoma (LADC) on survival is unclear, especially in Asian populations. In this study, we reviewed the prognostic outcomes of patients with late-stage disease according to the new grading system. We reviewed 136 LADC cases who underwent a small biopsy from 2007 to 2018.

Co-Expression of Coxsackievirus/Adenovirus Receptors and Desmoglein 2 in Lung Adenocarcinoma: A Comprehensive Analysis of Bioinformatics and Tissue Microarrays.

Introduction: Coxsackievirus/adenovirus receptors (CARs) and desmoglein-2 (DSG2) are similar molecules to adenovirus-based vectors in the cell membrane. They have been found to be associated with lung epithelial cell tumorigenesis and can be useful markers in predicting survival outcome in lung adenocarcinoma (LUAD).

Methods: A gene ontology enrichment analysis disclosed that DSG2 was highly correlated with CAR.

Nucleolar control by a non-apoptotic p53-caspases-deubiquitinylase axis promotes resistance to bacterial infection.

The nucleolus is best known for its cellular role in regulating ribosome production and growth. More recently, an unanticipated role for the nucleolus in innate immunity has recently emerged whereby downregulation of fibrillarin and nucleolar contraction confers pathogen resistance across taxa. The mechanism of this downregulation, however, remains obscure.

Anthelmintic activities of aporphine from Nelumbo nucifera Gaertn. cv. Rosa-plena against Hymenolepis nana.

Nelumbo nucifera Gaertn. cv. Rosa-plena (Nelumbonaceae), commonly known as lotus, is a perennial aquatic plant grown and consumed throughout Asia.

Dietary intake of vitamin B(6) and risk of breast cancer in Taiwanese women.

Background: B vitamins, including vitamin B(6), are coenzymes that are important for DNA integrity and stability. Deficiencies in B vitamins may promote tumor carcinogenesis.

Methods: We examined the association of dietary vitamin B(6) intake with overall breast cancer risk and breast cancers stratified by hormone receptor status.

Atg1-mediated myosin II activation regulates autophagosome formation during starvation-induced autophagy.

Autophagy is a membrane-mediated degradation process of macromolecule recycling. Although the formation of double-membrane degradation vesicles (autophagosomes) is known to have a central role in autophagy, the mechanism underlying this process remains elusive. The serine/threonine kinase Atg1 has a key role in the induction of autophagy.

Vitamin D decreases risk of breast cancer in premenopausal women of normal weight in subtropical taiwan.

Background: Evidence for an association between vitamin D status and breast cancer is now more convincing, but is uncertain in subtropical areas like Taiwan. This hospital-based case-control study examined the relationship of breast cancer with vitamin D intake and sunlight exposure.

Methods: A total of 200 incident breast cancer cases in a Taipei hospital were matched with 200 controls by date of interview and menopausal status.

Joint effect of peroxisome proliferator-activated receptor γ genetic polymorphisms and estrogen-related risk factors on breast cancer risk: results from a case-control study in Taiwan.

Peroxisome proliferator-activated receptor γ (PPARγ) has been linked with possible antineoplastic effects in colorectal carcinogenesis. However, data for the possible link between PPARγ and breast cancer risk are sparse. We assessed the association of three polymorphisms in PPARγ (rs10865710 [C-681T], rs1805192 [Pro12Ala], and rs3856806 [C1431T]) with the risk of breast cancer in an ethnic Chinese female population in Taiwan.

Increased matriptase zymogen activation in inflammatory skin disorders.

Matriptase, a type 2 transmembrane serine protease, and its inhibitor hepatocyte growth factor activator inhibitor (HAI)-1 are required for normal epidermal barrier function, and matriptase activity is tightly regulated during this process. We therefore hypothesized that this protease system might be deregulated in skin disease. To test this, we examined the level and activation state of matriptase in examples of 23 human skin disorders.

Adipocytokine resistin and breast cancer risk.

Adipocytokine resistin is a member of the newly discovered family of cysteine-rich protein. Recent data suggest that macrophages are a major source of human resistin. Given the obesity-breast cancer link and convergence of adipocyte and macrophage function, resistin may provide unique insight into links between obesity, inflammation, and breast cancer risk in humans.

Relationships between critical period of estrogen exposure and circulating levels of insulin-like growth factor-I (IGF-I) in breast cancer: evidence from a case-control study.

Epidemiological observations suggest that insulin-like growth factor-I (IGF-I), a potent mitogenic and anti-apoptotic peptide, plays a role in the etiology of breast cancer. Estrogen, which is crucial in breast carcinogenesis, both regulates and is influenced by IGF-I family. A case-control study was conducted to assess the role of IGF-I as a biomarker for breast cancer and to evaluate the potential joint effect of circulating IGF-I and critical period of estrogen exposure, as estimated by the interval between age at menarche and age at first full-term pregnancy on the risk of breast cancer.

Androgen receptor gene CAG repeats, estrogen exposure status, and breast cancer susceptibility.

The length of a polymorphic CAG repeat in exon 1 of the androgen receptor (AR) is inversely correlated with AR transactivation activity. As heightened androgenic stimulation may oppose breast cell proliferation, which is mediated by AR, we examined whether AR-CAG repeat lengths are related to breast cancer susceptibility. A nested case-control study of 88 newly diagnosed cases of breast cancer between 1992 and 2000 and 334 matched controls was carried out in Taiwanese women.

Anthropometric measures, plasma adiponectin, and breast cancer risk.

Adiponectin is a peptide hormone secreted exclusively by adipocytes, and obesity is an established risk factor for breast cancer. We have, thus, evaluated the associations of anthropometric measures of adiposity and adiponectin with the development of breast cancer in a case-control study. Questionnaire information, anthropometric measures, and blood samples were taken before treatment from 244 incident cases with breast cancer, including 141 premenopausal and 103 postmenopausal cases, and 244 controls admitted for health examination at the Tri-Service General Hospital, Taipei between 2004 and 2005.

Breast cancer risk associated with multigenotypic polymorphisms in folate-metabolizing genes: a nested case-control study in Taiwan.

Aim: The purpose of this study was to test the hypothesis that multigenotypic polymorphisms in the folate metabolic pathway, which may result in genomic instability and inbalance of estrogen metabolism, were associated with breast cancer risk.

Patients And Methods: A population-based nested case-control study of 109 cases with pathologically confirmed invasive breast cancer and 421 cancer-free controls was conducted in Taiwan between 1992 and 2001. The polymorphisms in serine hydroxymethyltransferase (SHMT1 C1420T), 5,10-methylenetetrahydrofolate reductase (MTHFR C677T), and methionine synthase (MS A2756G) genes were examined using polymerase chain reaction-restriction fragment length polymorphism.

Plasma homocysteine as a metabolic risk factor for breast cancer: findings from a case-control study in Taiwan.

Homocysteine (Hcy) is an intermediary product in methionine metabolism and an elevation in plasma Hcy is a sensitive biomarker for an imbalance in the integrated pathways of one-carbon metabolism. More recently, there has been interest in the potential links between total Hcy, folate and cancer. In this study, the association of plasma Hcy levels with the breast cancer risk was investigated.

Genetic polymorphisms of the methylenetetrahydrofolate reductase gene, plasma folate levels and breast cancer susceptibility: a case-control study in Taiwan.

Methylenetetrahydrofolate reductase (MTHFR) balances the pool of folate coenzymes in one-carbon metabolism for DNA synthesis and methylation, both are implicated in carcinogenesis. Two common variants in the MTHFR gene (C677T and A1298C) have been associated with reduced enzyme activity, thereby making MTHFR polymorphisms a potential candidate cancer-predisposing factor. To evaluate the C677T and A1298C functional polymorphisms in the MTHFR gene and their associations with breast cancer risk, as well as the potential modifying effect by plasma folate status on the MTHFR-associated risk, a hospital-based case-control study was conducted on a Taiwanese population consisting of 146 histologically confirmed incident breast cancer cases and their 285 age-matched controls without a history of cancer.

Polymorphic catechol-O-methyltransferase gene, duration of estrogen exposure, and breast cancer risk: a nested case-control study in Taiwan.

Background: Polymorphic catechol-O-methyltransferase (COMT) catalyzes the O-methylation of catechol estrogens, which are hypothesized to participate in estrogen-induced carcinogenesis.

Methods: We examined 87 cases and 341 population controls in Taiwan to determine the association between the functional genetic Val158Met polymorphism in membrane-bound form of COMT gene and female breast cancer risk. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by conditional logistic regression.
