ical role in regulating their entry into the myogenic programme. We had shown that in the Pax3/7 double mutant the myogenic determination genes, Myf5 and MyoD are not activated, leading to a major deficit in skeletal muscle. Pax3 directly activates Myf5, thus promoting a myogenic cell fate. However, it is essential to maintain a balance between differentiation and renewal of the progenitor cell...
The gene encoding ribosomal protein S19 (RPS19) has been shown to be mutated in 25% of the patients affected by Diamond-Blackfan anemia (DBA), a congenital erythroblastopenia. As the role of RPS19 in erythropoiesis is still to be defined, we performed studies on RPS19 expression during terminal erythroid differentiation. Comparative analysis of the genomic sequences of human and mouse RPS19 gen...
In vitro synthesis of a number of E. coli 30S ribosomal proteins has been demonstrated in a cell-free system consisting of ribosomes, initiation factors, RNA polymerase, a fraction containing soluble enzymes and factors, and E. coli DNA. DNA-dependent synthesis of the following 30S proteins has been demonstrated: S4, S5, S7, S8, S9, S10, S13, S14, S16, S19, and S20.
Brucellosis is an important zoonotic disease of nearly worldwide distribution. Despite the availability of live vaccine strains for bovine (S19 and RB51) and (Rev-1) for small ruminants but they have several drawbacks including residual virulence. So, in this study, gamma irradiated Brucella abortus vaccine prepared from an Egyptian field isolate was evaluated as a safe, stable and protective v...

Background: Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram nega...
An evaluation of a multiplex PCR assay (Bruce-ladder) was performed in seven laboratories using 625 Brucella strains from different animal and geographical origins. This robust test can differentiate in a single step all of the classical Brucella species, including those found in marine mammals and the S19, RB51, and Rev.1 vaccine strains.
In 2003, Aotearoa New Zealand (NZ) passed the Prostitution Reform Act 2003 (PRA), which decriminalized sex work for NZ citizens and holders of permanent residency (PR) while excluding migrant workers (MSWs) from its protection. This is due to Section 19 (s19) PRA, added at last minute against advice by Sex Workers’ Collective (NZPC) as an anti-trafficking clause. Because s19, migrants on tempor...
