Background: Insersion of subcutaneous poracath is im-portant in some cancer cases for whom chemotherapy isindicated. It is done either through image guided techniquein Intrerventional Departement or through blind technique inthe Surgical Departement.Aim of Study: We aimed in our study to to evaluate thecomplications and advantages of the two methodes used forportacath insertion (image-guided inserion and anatomicallandmark blind technique) and compare both to detect thebetter one should be used for the pateints.Patients and Methods: 110 adult cancer patients referredfrom the Medical Oncology Department outpatient clinics forsubcutaneous port catheter insertion in the period from January2019 to January 2020. 55 pateints underwent image-guidedinserion technique, while the other 55 pateints underwent theanatomical landmark blind technique. Data were collectedand analyzed. We campared the feasibility, advantages andcomplications of each technique.Results: The results showed obvious decreased complica-tions in image guided port catheter insertion compared toanatomical landmark blind technique in adult cancer patientsindicated for chemotherapy.Conclusion: Image guided portacath insertion is moresafe than anatomical landmark blind insertion.

Background: Chronic obstructive pulmonary disease (COPD) is one of the main causes of morbidity and mortality worldwide. Because of the progressive decline in lung function, it seriously affects their quality of life and their ability to work. COPD is a chronic inflammatory disease characterized by hypercoagulation. A persistent inflammatory response can cause hypercoagulation, possibly through cytokine-induced endothelium activation or by monocyte induction to express tissue factors. D-dimers are a marker of ongoing fibrin formation and degradation. Methods: Sampling was conducted during July 2019. Total population was 56 people (29 COPD patients and 27 non-COPD patients), the entire population was examined D-dimer, Spirometry and Brinkman index, then the results were compared in both populations. The study was conducted after obtaining ethical approval and informed consent. Results: There was no difference in the Brinkman Index between the COPD and non-COPD groups with a value of p = 0.369 (p Conclusions: Increased D-Dimer levels, in stable COPD patients, can be used to assess a prognosis and as a treatment for determining treatment in hospital.

Two homologous series of 4-alkoxyphenylazo 4ʹ-(2ʺ- (and 3ʺ-) methyl-) 4ʹ-substituted benzoates (IIna–f and IIIna–f, six series each) were prepared and investigated. Within each series, the length of the terminal alkoxy group varies among 6, 8, 10 and 12 carbons, while the other terminal substituent, X, is a polar group that alternatively changes between the electron-donating CH3O, CH3, and the electron-withdrawing Br, NO2 and CN groups, in addition to the un-substituted analogue, X = H, aiming to investigate the effect of the different orientations of the methyl groups substituted on the central benzene ring, on the mesophase behaviour. The mesomorphic properties were discussed in terms of steric and polarisability effects. The mesophase stability was correlated with the polarisability anisotropy of bonds to the terminal substituent X. Comparative studies were made between the prepared isomers with each other and with the previously investigated laterally neat analogues 4-(4ʹ-alkoxyphenylazo) phen...

Aims: This work was undertaken to study the effect of Aspergillus infection on phenolic compounds in beans from four cultivars of the coffee plant (Coffea arabica L.). The effects of storage conditions of the coffee beans were also examined. Methodology and results: Beans from four varieties of coffee were artificially infected with three species of Aspergillus: A. niger, A. melleus and A. alliacus, and stored at 0, 8 and 25 ± 2 °C). After 3, 6 and 9 months, the contents of phenolic compounds in the beans were determined using high performance liquid chromatography (HPLC). Conclusion, significance and impact study: The results of this study showed that phenolic compounds were qualitatively and quantitatively higher in the inoculated beans as compared with the uninfected control beans, reflecting a possible induced defense mechanism in the infected beans. Increased storage periods resulted in higher levels of phenols, but the average total, bound and free phenols did not differ between the cultivars tested. Effective control of Apergillus infection in coffee beans can prevent such changes in phenolics that may affect their commercial value.
