Tumor cells and their surrounding microenvironment produce a variety of growth factors and proteolytic enzymes to promote tumor growth and metastasis. We have recently identified a novel factor, termed com1, which is up-regulated in human breast carcinoma cells upon formation of experimental metastatic tumors and assumed to act as a growth-promoting factor in breast cancer. In attempts to explo...
Mechanistic studies are presented of a novel class of aminophosphine platinum(II) complexes as potential anticancer agents. These new agents, which have demonstrated activity against murine and human tumor cells including those resistant to cisplatin are cis-[PtCl2(Me2N(CH2)3PPh2-P)2] (Com1) and cis-[PtCl(C6H11NH(CH2)2PPh2-N,P)(C6H11NH(CH2) 2PPh2-P)] (Com2). We studied modifications of natural ...
Currently, the accepted method for Q fever serodiagnosis is indirect immunofluorescent antibody assay (IFA) using the whole cell antigen. In this study, we prepared the recombinant antigen of the 27-kDa outer membrane protein (Com1) which has been shown to be recognized by Q fever patient sera. The performance of recombinant Com1 was evaluated in ELISA by IFA confirmed serum samples. Due to the...
The model archaeon Pyrococcus furiosus grows optimally near 100°C on carbohydrates and peptides. Its genome sequence (NCBI) was determined 12 years ago. A genetically tractable strain, COM1, was very recently reported, and here we describe its genome sequence. Of 1,909,827 bp in size, it is 1,571 bp longer (0.1%) than the reference NCBI sequence. The COM1 genome contains numerous chromosomal re...
A nested PCR method was developed for the detection of Coxiella burnetii in human serum samples. Two pairs of oligonucleotide primers were designed to amplify a 438-bp fragment of the com1 gene encoding a 27-kDa outer membrane protein of C. burnetii. The primers amplified the predicted fragments of 21 various strains of C. burnetii but did not react with DNA samples from other microorganisms. T...
Obligatory homologous recombination (HR) is required for chiasma formation and chromosome segregation in meiosis I. Meiotic HR is initiated by DNA double-strand breaks (DSBs), generated by Spo11, a homologue of the archaebacterial topoisomerase subunit Top6A. In Saccharomyces cerevisiae, Rad50, Mre11 and Com1/Sae2 are essential to process an intermediate of the cleavage reaction consisting of S...
Coxiella burnetiiis an obligate and gram-negative bacteria causing query fever (Q fever) disease, despite the importance of Q fever, there is no universal vaccine against this disease. Therefore, application of the recombinant subunit vaccines which use Com1 and OmpH as immunogenic proteins can be useful in this regard. To perform the current project, Com1 an...
The gene for an approximately 27-kDa outer membrane-associated, immunoreactive protein was cloned from the rickettsial pathogen Coxiella burnetii. The gene, designated com1 for Coxiella outer membrane protein 1, was expressed in Escherichia coli, presumably by its own promoter. The complete nucleotide sequence of the gene was determined. The deduced amino acid sequence of 252 residues includes ...

In hyper-arid and arid zones, management of crop water requirements is considered a vital component for sustaining production. The efficiency the irrigation method application many kinds organic matter are practices that should be followed in Egypt to maximize use water. Two field experiments were conducted during two successive winter seasons 2020/2021 2021/2022 study effect drip systems sever...
