To study the role of sulfhydryl group formation during cell cycle progression, mammalian tissue culture cells (PTK2) were exposed to 100¼M 2-mercaptoethanol for 2 to 6 h during their exponential phase of growth. The effects of 2-mercaptoethanol on centrosomes, chromosomes, microtubules, membranes and intermediate filaments were analyzed by transmission electron microscopy (TEM) and by immunofluorescence microscopy (IFM) methods using a human autoimmune antibody directed against centrosomes (SPJ), and a mouse monoclonal antibody directed against tubulin (E7). Chromosomes were affected most by this treatment: premature chromosome condensation was detected in interphase nuclei, and the structure in mitotic chromosomes was altered compared to control cells. This would support previous findings in dividing sea urchin cells in which chromosomes are arrested at metaphase while the centrosome splitting cycle continues. It might also support findings that certairt-sulfhydryl-blocking agents block cyclin destruction. The organization of the microtubule network was scattered probably due to a looser organization of centrosomal material at the interphase centers and at the mitotic poles.

The International Labour Organization in Beirut has been running a project in the Palestinian Camps of Nahr El Bared and Ein El Helweh entitled “Palestinian Women Economic Empowerment Initiative”. The project started in 2011 and targets lowincome Palestinian women entrepreneurs through a threefold strategy: giving out loans and grants to women business groups in order to expand their businesses; training women entrepreneurs to enhance their business skills; and building the capacity of support organizations in order to improve business development services for women entrepreneurs and training them to be formally certified to deliver business group formation training. The project builds on the potential of business groups in assuring the protection of Palestinian women entrepreneurs from risks through resilience, pooling of resources, and collective voice. The objectives are to assure a sustainable livelihood for Palestinian women entrepreneurs through supporting them in expanding their businesses beyond survivalist low-income activities
