25. Effect of LPS on the Viability and Proliferation of Human Oral and Esophageal Cancer Cell Lines
The esophagus and mouth tumors are very frequent malignancies worldwide. Lipopolysaccharides (LPS) are capable of regulating gene expression of pro-inflammatory cytokines by binding to toll-like receptor 4 (TLR4). Recent studies show that LPS can increase the migration ability of human esophageal cancer cell line HKESC-2 by increasing its adhesion properties

26. small ORFs: A new class of essential genes for development
Genes that contain small open reading frames (smORFs) constitute a new group of eukaryotic genes and are expected to represent 5% of the Drosophila melanogaster transcribed genes. In this review we provide a historical perspective of their recent discovery, describe their general mechanism and discuss the importance of smORFs for future genomic and transcrip

27. Auxinic herbicides, mechanisms of action, and weed resistance: A look into recent plant science advances
Auxin governs dynamic cellular processes involved at several stages of plant growth and development. In this review, we discuss the mechanisms employed by auxin in light of recent scientific advances, with a focus on synthetic auxins as herbicides and synthetic auxin resistance mechanisms. Two auxin receptors were reported. The plasma membrane receptor ABP1

28. The effect of elemene on lung adenocarcinoma A549 cell radiosensitivity and elucidation of its mechanism
OBJECTIVE:To investigate the effect of elemene on the radiosensitivity of A549 cells and its possible molecular mechanism.METHODS:Apoptosis of A549 cells was detected by flow cytometry and fluorescence microscopy. The effect of double-strand break (DSB) damage repair in A549 cells was evaluated using the neutral comet assay. Protein expression levels were de

29. Biodegradation of crude oil by individual bacterial strains and a mixed bacterial consortium
Three bacterial isolates identified as Alcanivorax borkumensis SK2, Rhodococcus erythropolis HS4 and Pseudomonas stutzeri SDM, based on 16S rRNA gene sequences, were isolated from crude oil enrichments of natural seawater. Single strains and four bacterial consortia designed by mixing the single bacterial cultures respectively in the following ratios: (Alcan

30. Toll-like receptor 3 (TLR3) and the development of type 1 diabetes mellitus
Type 1 diabetes mellitus (T1DM) is a chronic, progressive autoimmune disease characterized by metabolic decompensation often leading to dehydration and ketoacidosis. Viral agents seem to play an important role in triggering the autoimmune destruction that leads to the development of T1DM. Among several viral strains investigated so far, the enterovirus famil

31. Sociología política de las elites. Apuntes sobre su abordaje a través de entrevistas
This article examines the challenges and potential of the historical and qualitative approach of political elites, particularly through in-depth interviews. We point out some questions for which this methodology is particularly relevant and we reconstruct the main challenges entailed by the fieldwork among leading sectors. The article is based on a research

32. De novo alpha 2 hemoglobin gene (HBA2) mutation in a child with hemoglobin M Iwate and symptomatic methemoglobinemia since birth
Cyanosis in an apparently healthy newborn baby may be caused by hemoglobin variants associated with the formation of methemoglobin, collectively known as M hemoglobins. They should not be confused with genetic alterations in methemoglobin reductase enzyme systems of red cells since treatment and prognosis are completely different. A newborn male child was no

33. Association of glucocorticoid receptor polymorphisms with clinical and metabolic profiles in polycystic ovary syndrome
OBJECTIVES: We aimed to investigate whether glucocorticoid receptor gene polymorphisms are associated with clinical and metabolic profiles in patients with polycystic ovary syndrome. Polycystic ovary syndrome is a complex endocrine disease that affects 5-8% of women and may be associated with metabolic syndrome, which is a risk factor for cardiovascular dis

34. Plant regeneration and Agrobacterium-mediated transformation of Achyranthes bidentata using cotton EREBP gene
The aim of this work was to study the plant regeneration and Agrobacterium-mediated transformation of Achyranthes bidentata using cotton EREBP gene. Results showed that the callus induction rate of stems from A. bidentata was the highest (100%) and bud was in approximately 70% of calli from stems. However bud differentiation rate of the callus from leaves an

35. Action of phosphorylated mannanoligosaccharides on immune and hematological responses and fecal consistency of dogs experimentally infected with enteropathogenic Escherichia coli strains
The therapeutic action of phosphorylated mannanoligosaccharides (MOS) was investigated regarding its prebiotic activity on enteropathogenic Escherichia coli (EPEC). Diarrhea was induced in dogs by experimental infection with EPEC strains. Then MOS was supplied once a day, in water for 20 days. Immunological (IgA and IgG), hematological (lymphocytes, neutroph

36. Epistasis interaction of QTL effects as a genetic parameter influencing estimation of the genetic additive effect
Epistasis, an additive-by-additive interaction between quantitative trait loci, has been defined as a deviation from the sum of independent effects of individual genes. Epistasis between QTLs assayed in populations segregating for an entire genome has been found at a frequency close to that expected by chance alone. Recently, epistatic effects have been cons
