Published: January 2012

The direct coupling of unactivated carboxylic acids with amines can be performed in toluene 110 °C in the absence of catalyst. The use of simple zirconium catalysts at 5 mol% loading gave amide formation in as little as 4 h.

Oncogenic role of RARG rearrangements in acute myeloid leukemia resembling acute promyelocytic leukemia.

Acute myeloid leukemia (AML) featuring retinoic acid receptor-gamma (RARG) rearrangements exhibits morphological features resembling those of acute promyelocytic leukemia but is associated with drug resistance and poor clinical outcomes. However, the mechanisms underlying the role of RARG fusions in leukemogenesis remain elusive. Here, we show that RARG fusions disrupt myeloid differentiation and promote proliferation and self-renewal of hematopoietic stem and progenitor cells (HSPCs) by upregulating BCL2 and ATF3.

The increasing incidence of infections attributed to hypervirulent carbapenem-resistant (Hv-CRKp) is of considerable concern. Bacteriophages, also known as phages, are viruses that specifically infect bacteria; thus, phage-based therapies offer promising alternatives to antibiotic treatments targeting Hv-CRKp infections. In this study, two isolated bacteriophages, Kpph1 and Kpph9, were characterized for their specificity against the Hv-CRKp NUHL30457 strain that possesses a K2 capsule serotype.

Department of Pharmacology and Toxicology, Faculty of Pharmacy, Beni-Suef University, Beni-Suef, 62514, Egypt.

Drug repurposing of well-established drugs to be targeted against lung cancer has been a promising strategy. Bosentan is an endothelin 1 (ET-1) blocker widely used in pulmonary hypertension. The current experiment intends to inspect the anticancer and antiangiogenic mechanism of bosentan targeting epidermal growth factor receptor (EGFR) /extra-cellular Signal Regulated Kinase (ERK) /c-Jun/vascular endothelial growth factor (VEGF) carcinogenic pathway.

This study attempts to prove that the antioxidant effect of fucoxanthin nanoparticles can prevent streptozotocin-induced rat liver damage. Fucoxanthin nanoparticles are synthesized using the high-energy ball milling method. Dynamic Light Scattering (DLS) was then used to describe the sizes of the fucoxanthin nanoparticles.
