Aim: Honey is not always a safe product and in some instances it is spoiled by the growth of micro-organisms. The aim of the study was to characterize honey on biological and physicochemical basis. Study Design: Determination of the microbial loads in the Sudanese honey brands and characterization of their physicochemical properties. Methodologies: Several microbiological tests were employed for the determination of the microbial loads. The methods of Association of the Official Analytical Chemists were employed for the physicochemical properties. Results: The microbiological tests were negative for Escherichia coli, and total coliforms (mpn/ml). Few honey brands contained Clostridium botulinum, Salmonella, Staphylococcus aureus, yeasts and moulds. The maximum total viable bacteria count was > 3.77 log. cfu/ml. The results of the physical parameters tested were as follows: pH 3.6, specific gravity 1.2, viscosity 120.7 Poise, and refractive index 1.4., moisture 18.2%, acidity 54.2 (meq/kg), total sugars 70.5%, fructose 32.1%, glucose 32.8%, and sucrose 5.5%. Conclusion:The physicochemical properties of the investigated samples comply with the Codex Alimintarius Standards for honey. However, some honey brands contained yeasts, moulds, as well as some pathogenic bacteria such as Salmonella spp, Staphylococcus aureus, Clostridium botulinum. Thus the study justified the importance of the proper

Ubiquitin protein has a conserved amino acid sequence, found in all eukaryotes and it is important in many of cellular functions .The increase or decrease in the ubiquitin level lead to causing many diseases including cancer .The aim of this study is to measure the concentration of ubiquitin c protein in blood serum of lung cancer patients and healthy control subjects by using ELISA technique. The Mean ± SD for ubiquitin c protein was (7.51 ± 5.76) in   blood serum of the normal healthy subject and   Std. Error mean was (1.82). While the Mean ± SD was (10.99 ± 4.56  ) for ubiquitin c protein in serum of  lung cancer patients and Std. Error mean  was  (1.44) .The results showed no statistically  significance the P value ( 0.15)  between  the  protein concentration in the serum of patients with lung cancer compared to the serum concentration of healthy normal  subjects.

In the present study, sequencing approach has been adopted for exploring the ‎genetic alteration of sequences for the ubiquitin gene (UBC) in patients of breast and ‎lung cancer and comparing the results with a normal sequence that obtained from NCBI. ‎The aim of this study was to detect for genetic alterations of UBC gene in the breast and ‎lung cancer patients then compare with healthy control subjects, to investigate the ‎association between the mutations at the intron region of the UBC gene and cancer disease, ‎‎40 blood samples were examined from patients with breast and lung cancer aged ranged from (17-65) years, were collected at Al-Amal Hospital of cancer in Baghdad ‎province/Iraq, the period of collecting samples were from October/2018 to January/2019. ‎While twenty-two blood samples from healthy control subjects were collected at ages ‎ranged from(19-59). After DNA extraction, the PCR primer was designed to amplify the ‎region in the UBC gene (part of exon 1 and the whole intron). Here we report the polymorphism of the intron sequence of the UBC gene in Iraqi population as the results of sequencing the PCR amplified products showed three different transition mutation G→A, ‎C→T, T→C in patients with breast cancer were also appeared in healthy control subjects. While nine transition mutations appeared in lung cancer patients, at different locations ‎of the sequence were detected by BLAST tool. ‎
