It has long been a goal of science education in the United States that students leave school with a robust understanding of the nature of science. Decades of research show that this does not happen. Inquiry-based instruction is advocated as a means for developing such understanding, although there is scant direct evidence that it does. There is a gap between what is known about students’ inquir...

BACKGROUND The multiple endocrine neoplasia 2 (MEN 2) syndromes [MEN 2A, MEN 2B, and familial medullary thyroid carcinoma (FMTC)] are caused by germline mutations of the RET protooncogene. Because 85% of MEN 2A patients and 30% of FMTC patients have mutations at codon 634, the recommended molecular analyses begin at exon 11, where codon 634 is located. METHODS We scanned codon 634 of the RET ...

The quantum yield of photosystem II, determined by chlorophyll fluorescence and the quantum yield of CO2 uptake, determined from gas exchange, are two physiologically important measurements in clarifying the response to environmental stress. Both measurements, however, require an accurate assessment of leaf light absorption in the photosynthetically active radiation wavelength range (400–700 nm...

Apurinic/apyrimidinic endonuclease 1 (APE1) is an essential enzyme in the base excision repair pathway, which is the primary mechanism for the repair of DNA damage caused by oxidation and alkylation. We hypothesized that polymorphisms of APE1 are associated with risk for lung cancer. In the hospital-based matched case-control study, a total of 730 lung cancer cases and 730 cancer-free controls ...

To investigate the role of circ_0084927 in lung cancer cell sensitivity to cisplatin. Half-maximal inhibitory concentration value cisplatin was detected by counting kit-8. and microRNA-634 expression were determined reverse transcription quantitative polymerase chain reaction. Cell kit-8, scratch healing, colony formation as well Transwell experiments used for analyzing viability, healing rate,...

Abstract Background In the evaluation of specific non MINOCA, differential diagnosis between Takotsubo syndrome and myocarditis can be challenging. Purpose The aim our study was to evaluate parameters that more useful distinguish pathologies. Methods All patients with MINOCA admitted service were enrolled. Informations about clinical characteristic, in-hospital outcome complications collected. ...

Glioblastoma multiforme is characterized by rapid proliferation, aggressive metastatic potential, and resistance to radio- and chemotherapy. The matricellular protein CYR61 regulates cellular proliferation and migration and is highly expressed in Glioblastomas. MicroRNAs are 22-nucleotides long RNAs that regulate gene expression post-transcriptionally. Here, we utilized the LN229 glioblastoma c...

The article discusses and analyzes data from several economic experiments in a household sur-vey with mothers of preschool children. The researchers measured competitiveness by giving the subjects the choice between competing in a tournament or receiving a piece rate for a real effort task. The subjects also participated in lottery choices, which enabled the researchers to assess their risk pre...
