Synechococcus elongatus PCC 7942 is an excellent model system for studying the molecular mechanism of the circadian clock in cyanobacteria. The "plastic" genetic characteristics of this organism have facilitated the development of various methods for mutagenesis of its chromosome. These methods are based on homologous recombination between the chromosome and foreign DNA, introduced to the cyanobacteria by either transformation or conjugation. Here we describe different approaches to mutagenize the chromosome of S. elongatus, including insertional mutagenesis, hit-and-run allele replacement, rps12-mediated gene replacement, and regulated expression of genes from ectopic sites, the neutral sites of the S. elongatus genome.

Official development agencies are increasingly supporting civil society lobby and advocacy (L&A) to address poverty and human rights. However, there are challenges in evaluating L&A. As programme objectives are often to change policies or practices in a single institution like a Government Ministry, L&A programmes are often not amenable to large-n impact evaluation methods.

Purpose: To evaluate the diagnostic value of different subtypes of non-punctate echogenic foci in thyroid malignancy.
Methods: Retrospective research of 342 thyroid nodules with calcification was performed. The echogenic foci were divided into punctate echogenic foci (type I) and non-punctate echogenic foci (type II), and type II were further divided into four subtypes: macrocalcification (type IIa), continuous peripheral calcification (type IIb), discontinuous peripheral calcification (type IIc) and isolated calcification (type IId).
New insights into the interplay between MALAT1 and miRNA-155 to unravel potential diagnostic and prognostic biomarkers of Behçet's disease.

Biochemistry Department, Faculty of Pharmacy, Cairo University, Cairo, 11562, Egypt.
The current study was deployed to evaluate the role of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) and miR-155, along with the inflammatory markers, TNFα and IL-6, and the adhesion molecule, cluster of differentiation 106 (CD106), in Behçet's disease (BD) pathogenesis. The study also assessed MALAT1/miR-155 as promising diagnostic and prognostic biomarkers for BD. The current retrospective case-control study included 74 Egyptian BD patients and 50 age and sex-matched controls.

Background: Amiodarone is an effective anti-arrhythmic drug; however, it is frequently associated with thyroid dysfunction. The aim of this study was to investigate the incidence and risk factor of amiodarone-induced dysfunction in an iodine-sufficient area.
Methods: This retrospective cohort study included 27,023 consecutive patients treated with amiodarone for arrhythmia, using the Korean National Health Insurance database.
