These beads were produced utilizing the ionotropic gelation technique. Methylene blue (MB) was employed as a drug model to evaluate the kinetics of drug release and the capacity of the synthesized beads to function as a drug delivery system. The molecular interaction between sodium alginate and myrrh was confirmed by FTIR spectroscopy. The physical characteristics of the Myrrh-Alginate beads, including drug content, particle size, thermal properties, equilibrium water content (EWC), swelling behavior, and equilibrium swelling ratio (ESR), were studied to establish the hydrogel's response type, as well as the releasing kinetics at 37°C and in Phosphate buffer solution (PBS) at pH = 6.8 and 10. All beads (loaded and unloaded) were analyzed by Differential scanning calorimetry, Scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD). The drug content percentages of the Myrrh-Alginate beads increased with a moderate fraction (5% ) of Myrrh but dropped with a higher Myrrh percentage. The Myrrh-Alginate beads absorbed more water and swelled more than the pure calcium alginate beads (S2) in pH 6.8 and 10 of (PBS). In a pH 6.8 of (PBS), the Myrrh-Alginate beads demonstrated a controlled and regulated style of releasing and demonstrated a high match with the Korsmeyer-Peppas model as they had the maximum values of the correlation factor (R2) in this model.","PeriodicalId":21627,"journal":{"name":"Science Journal of University of Zakho","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86927135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence the need to investigate and compare the effect of expired and non-expired pendimethalin and hand weeding on weed suppression, growth, yield and composition of groundnut. The experiment was carried out during therainy season in 2020. It consisted of seven weed control treatments. These were sole pendimethalin non-expired (T1), pendimethalin non-expired + one hand weeding at 6 weeks after sowing (T2), pendimethalin expired (T3), pendimethalin expired + one hand weeding at 6 WAS (T4), two hand weeding at 3 and 6 WAS (T5), weed free check (T6) and weedy check (T7). Desmodium trifolium, Amaranthus spinosusand Commelina benghalensis were the most preponderant weedspecies. Both expired or non-expired pendimethalin and their integration with one hand weeding reduced weed population than other treatments. Pendimethalin non-expired + one hand weeding at 6WAS and two hand weeding at 3 and 6 WAS significantly increased the growth parameters and yield when compared with other treatments. In this study, two hand weeding at 3 and 6 WAS and non-expired pendimethalin + one hand weeding 6 WAS, should be reinforced for weed control on account of their positive influence on groundnut productivity and seed quality.","PeriodicalId":21627,"journal":{"name":"Science Journal of University of Zakho","volume":"39 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82833874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollution load index (PLI), Nemerow pollution index (PIN), Potential Ecological Risk (PER) and Geo-accumulation Index (Igeo) were also calculated according to the internationally approved methods. The results indicated that most of lead, nickel and copper concentrations in soils and sediments exceeded the limits allowed by WHO, reaching annual rates (96.758, 168.746 and 29.88) , (111.25, 219.65 and 48.162) mg.kg-1, respectively. This fluctuation in concentrations was reflected in the values of the studied indicators for both soil and sediment, where 50% and 58% of the studied specimen are of the polluted grade and the remnant are of the non-polluted grade according to the PLI values. So is the case with PIN where 58% of the soil specimen and 41.6% of the sediment samples were of the severe pollution grade, while 25% and 33.3% of the specimen were of the heavy pollution grade and the remnant were slightly pollution grade. The same applies to the results of the PER index values, where 50% and 41.67% of the specimen were from the Medium ecological risk category, and the rest were from the low ecological risk category, likewise for the (Igeo) values, 100% and 96% of the soil and sediment samples were from the Weakly polluted category.","PeriodicalId":21627,"journal":{"name":"Science Journal of University of Zakho","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84535148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the current study was to identify S. aureus with methicillin-resistant S. aureus (MRSA). Moreover, it aimed to determine their antimicrobial susceptibility patterns and to detect the presence of the mecA, lukPV and icaA genes in isolated S. aureus among UTIs patients. A total of 402 urine samples were collected from patients diagnosed with UTIs aged (less than 80 years) at Zakho General Hospital in Zakho City, from August 2021 to March 2022. From these samples, a total of 37 (12.6%) S. aureus was identified and molecularly confirmed by the nuc gene. A high prevalence of MRSA 28 (75.7%) was identified from these isolates S. aureus by Oxacillin sensitive test and confirmed by mecA gene. Females were highly infected with UTIs than males, and most cases were in chronic condition and married. In addition, 18 (64.3%) and 21 (75%) of these isolates S. aureus were harbored luk-PV and icaA genes, respectively. There were widespread of antimicrobial resistance patterns for these bacteria. Isolated MRSA were highly sensitive to Imipenem. Interestingly, a significant positive correlation between mecA and both virulence marker genes (luk-PV and icaA) found in MRSA with UTIs. Conclusion, the data demonstrated, for the first time, alarming emergence of multidrug-resistant MRSA isolated from UTIs of community-acquired in Kurdistan Region-Iraq.
