Activation of NF-κB by SOD2 promotes the aggressiveness of lung adenocarcinoma by modulating NKX2-1-mediated IKKβ expression

Magnesium superoxide dismutase (SOD2) has been shown to cause dysfunction of p53 transcriptional activity, whereas, in turn, SOD2 expression is regulated by p53 to modulate lung tumorigenesis. In this study, we found that the level of SOD2 expression in a panel of lung cancer cells was negatively correlated with that of NK2 homeobox 1 (NKX2-1) but was not associated with p53...

Poor Responses to Interferon-Beta Treatment in Patients with Neuromyelitis Optica and Multiple Sclerosis with Long Spinal Cord Lesions

Interferon-beta (IFN-β) treatment may not be effective in neuromyelitis optica (NMO). Whether the poor response to IFN-β is related to long spinal cord lesions (LSCL) or the NMO disease entity itself is unclear. We evaluated the spinal cord involvement of patients with multiple sclerosis (MS) and NMO, as well as the response after receiving IFN-β. Forty-nine MS and 21 NMO...

Achievements and Challenges of CdS/CdTe Solar Cells

Thin film CdS/CdTe has long been regarded as one promising choice for the development of cost-effective and reliable solar cells. Efficiency as high as 16.5% has been achieved in CdS/CdTe heterojunction structure in laboratory in 2001, and current techniques for CdS/CdTe solar cells gradually step toward commercialization. This paper reviews some novel techniques mainly within...

Factors Contributing to De Qi in Acupuncture Randomized Clinical Trials

De qi is a core concept of acupuncture and is necessary to produce therapeutic effect. In 2010, de qi has been received as a term in the official extension of the CONSORT Statement. However, there are few articles that discuss which factors have influences on obtaining de qi in clinical trials. This paper aims to explore these factors and give advice on trial design in order to...

Dr. Chen-lu Tsou: a tireless advocate for advancement in the standards of scientific research in China

English journals independently, which is the first step to internationalization. On the Chih-chen Wang et al. other hand, it is necessary to apply internationally approved scientific writing standards and

Regulatory T Cells Are Protective in Systemic Inflammation Response Syndrome Induced by Zymosan in Mice

Systemic inflammation response syndrome (SIRS) is a key and mainly detrimental process in the pathophysiology of multiple organ dysfunction syndrome. The balance of pro-inflammation and anti-inflammation controls the initiation and development of SIRS. However, the endogenous counterregulatory immune mechanisms that are involved in the development of SIRS are not well understood...

Retrospective study of biopsied head and neck lesions in a cohort of referral Taiwanese patients

Introduction A study of the whole spectrum of biopsied head and neck (HN) diseases in Taiwan has not yet been performed. Therefore, the current study aimed to provide updated information about HN lesions in a cohort of referral Taiwanese patients for histopathological examination. Methods HN lesions (2000–2011) in patients with records of age, sex, and histological diagnoses were...

miR-203 Suppresses the Proliferation and Migration and Promotes the Apoptosis of Lung Cancer Cells by Targeting SRC

SRC, also known as proto-oncogene c-Src, is a non-receptor tyrosine kinase that plays an important role in cancer progression by promoting survival, angiogenesis, proliferation, and invasion pathways. In this study, we found that SRC protein levels were consistently upregulated in lung cancer tissues, but that SRC mRNA levels varied randomly, suggesting that a post...

Gene signature model for breast cancer risk prediction for women with sclerosing adenosis

Benign breast disease (BBD) is diagnosed in 1–2 million women/year in the US, and while these patients are known to be at substantially increased risk for subsequent development of breast cancer, existing models for risk assessment perform poorly at the individual level. Here, we describe a DNA-microarray-based transcriptional model for breast cancer risk prediction for patients...

Proteomic-Based Insight into Malpighian Tubules of Silkworm Bombyx mori

Malpighian tubules (MTs) are highly specific organs of arthropods (Insecta, Myriapoda and Arachnida) for excretion and osmoregulation. In order to highlight the important genes and pathways involved in multi-functions of MTs, we performed a systematic proteomic analysis of silkworm MTs in the present work. Totally, 1,367 proteins were identified by one-dimensional gel...

Microarray Analysis Reveals Potential Biological Functions of Histone H2B Monoubiquitination

Histone H2B monoubiquitination is a key histone modification that has significant effects on chromatin higher-order structure and gene transcription. Multiple biological processes have been suggested to be tightly related to the dynamics of H2B monoubiquitination. However, a comprehensive understanding of biological roles of H2B monoubiquitination is still poorly understood. In...

Rapamycin promoted thrombosis and platelet adhesion to endothelial cells by inducing membrane remodeling

Background Recently, evidence indicated that the rapamycin-eluting stent which was used worldwide may contribute to an increased risk for thrombosis. On the contrary, other researchers found it was safe. Thus, it is necessary to clarify the effect of rapamycin on thrombosis and the corresponding mechanisms. Results The effects of rapamycin in vivo were evaluated by modified deep...

The Role of Growth Retardation in Lasting Effects of Neonatal Dexamethasone Treatment on Hippocampal Synaptic Function

Background Dexamethasone (DEX), a synthetic glucocorticoid, is commonly used to prevent or lessen the morbidity of chronic lung disease in preterm infants. However, evidence is now increasing that this clinical practice negatively affects somatic growth and may result in long-lasting neurodevelopmental deficits. We therefore hypothesized that supporting normal somatic growth may...

Distributed Transmit Beamforming without Phase Feedback

Phase feedback and adjustment between wireless nodes greatly reduce the power efficiency of distributed beamforming. In this paper, we propose a distributed transmit beamforming method without any phase feedback between nodes. The concept of our approach is to have the received signals retrace their ways, so that the phase offset of the forward path compensates that of the...

Retroperitoneal paraganglioma manifesting as paralytic ileus: a case report

IntroductionRetroperitoneal neoplasms are rare and easily misdiagnosed. These tumors are often discovered incidentally during imaging studies performed for other reasons. Paragangliomas are tumors that arise from extra-adrenal medullary neural crest derivatives. They are usually located in the head and neck but can be found in various body sites, including the chest cavity...

A reverse transcriptase-related protein mediates phage resistance and polymerizes untemplated DNA in vitro

Reverse transcriptases (RTs) are RNA-dependent DNA polymerases that usually function in the replication of selfish DNAs such as retrotransposons and retroviruses. Here, we have biochemically characterized a RT-related protein, AbiK, which is required for abortive phage infection in the Gram-positive bacterium Lactococcus lactis. In vitro, AbiK does not exhibit the properties...

Identification and functional analysis of mitogen-activated protein kinase kinase kinase (MAPKKK) genes in canola (Brassica napus L.)

Mitogen-activated protein kinase (MAPK) signalling cascades, consisting of three types of reversibly phosphorylated kinases (MAPKKK, MAPKK, and MAPK), are involved in important processes including plant immunity and hormone responses. The MAPKKKs comprise the largest family in the MAPK cascades, yet only a few of these genes have been associated with physiological functions, even...

miR-203 Inhibits Cell Proliferation and Migration of Lung Cancer Cells by Targeting PKCα

PKCα (protein kinase C alpha, PRKCA) is an important protein involved in several steps of signaling pathways in lung cancer, and microRNAs (miRNAs) have also been shown to participate in lung carcinogenesis. However, it is not clear how PKCα and miRNAs are correlated in the disease. In this report, we aimed to identify novel miRNAs that target PKCα and to study their biological...
