The nature of gene mutations induced by ionizing radiation in germ cells and transmitted to offspring remains one of the most important problems in radiation genetics of higher eukaryotes. The data accumulated in this field were obtained by different authors under different experimental conditions which does not give a complete insight about the nature of radiation-induced inherited mutations at different genome levels (chromosome, gene, DNA).
Escherichia coli Stress, Multi-cellularity, and the Generation of the Quorum Sensing Peptide EDF
Bacterial communication via quorum sensing (QS) molecules, as well as toxin-antitoxin (TA) gene modules located on bacterial chromosomes are well-studied mechanisms. Escherichia coli mazEF is a stress-induced TA system mediating cell death requiring a QS extracellular death factor (EDF), the pentapeptide NNWNN. MazF is an endoribonuclease specific for ACA sites. During adverse conditions, the activated MazF generates a stress induced translation machinery, composed of MazF-processed mRNAs and selective ribosomes that specifically translate these processed mRNAs.
Mega-Dose Dietary Riboflavin in Treatment in Keratoconus, Post-Refractive Cornea Ectasia and Migraine. Has Its Time Arrived?

Generating Awareness and a Planned Multidisciplinary Treatment Approach Can Save Both the Sight and Life in Retinoblastoma in Developing Countries
While rare, retinoblastoma is the most common (1:16000 – 18000 live births) intraocular and life threatening tumor of childhood [1,2]. According to the World Health Organization (WHO), 66% of children present with symptoms before 2 years of age and 95% before 5 years of age. About 8000 new cases are detected annually with the highest incidence in Africa and India. In fact, more than 1400 cases each year are from India [3].
The Effect of Glucocorticoids on Angiogenesis in the Treatment of Solid Tumors
Glucocorticoids (GCs) are defined by their role in maintaining glucose homeostasis and natural GCs are a class of corticosteroids secreted by the adrenal cortex. Cortisol is the most important natural GC in humans. Cellular cortisol levels are regulated by the tissue-specific metabolic enzymes 11β-hydroxysteroid dehydrogenase 1 and 2 (11β-HSD 1 and 2); 11β-HSD 1 converts inactive cortisone to active cortisol, while 11β-HSD 2 has the opposite function.
Distinct Phosphorylation of STAT1 Confers Distinct DNA Binding and Gene-regulatory Properties
Signal transducer and activator of transcription 1 (STAT1) protein plays a pivotal role in various biological processes especially the regulation of innate and adaptive immune responses. Phosphorylation represents a key step in the activation of STAT1 and its transcriptional outcome. Binding of various extracellular ligands to their specific cell-surface receptors activates different phosphorylation of STAT1 followed by a distinct change of gene expression patterns.
Learning from Pitfall and Error: A Usefulness of Case Report
Case report is an important kind of article in medicine. The case report can be in several forms. A report might be on the new finding, new technique, rare condition or lesson learnt [1-2]. The case report on pitfall and error is interesting. It is useful for giving lesson learnt to the reader.
Molecular Detection of Plasmid - Mediated Quinolone Resistant Genes in Uropathogenic E. coli from Tertiary Referral Hospital in Tehran , Iran
Urinary Tract Infection (UTI) due to Escherichia coli is the most common bacterial infection. Fluoroquinolones are commonly used for the treatment of UTI because isolated microorganisms are frequently resistant to aminopenicillins and trimethoprim- sulfamethoxazole and fluoroquinolones are given orally [1].
Forces, Chromosomal Configurations, and Carcinogenesis: Towards Another Therapeutic Approach
Various types of forces, such as cohesive and adhesive forces, are involved in physical and biological processes. Many of these processes appear to have developmental features through different scales of nature, and such processes may reflect a universal dynamic of accommodation involving the universal dimensional constants

The Link of Nutrient Fluxes to Hepatic Insulin Resistance at Gene Expression
Insulin resistance has been studied extensively at systemic, organ, tissue and cellular and molecular levels. Overnutrition plays an essential role in the development of chronic metabolic diseases such as obesity and type 2 diabetes. For subjects without genetic defects, the development of insulin resistance and type 2 diabetes is a graduate process. How the transition from an insulinsensitive state to an insulin-resistant state occurs, and what the roles of nutrients are in the process have not been fully understood. Here, we try to summarize the current understanding of insulin-regulate gene expression in the liver, and describe a phenomenon of hepatic insulin resistance at gene expression (HIRAGE), which may be linked to overnutrition.
