Antibiotics called macrolide, lincosamide and streptogramin B (MLS
) are being used to treat staphylococci infections. Multiple pathways that impart resistance to MLS
antibiotics have been confirmed to cause clinical failure. The present work aimed to determine the frequency of constitutive and inducible clindamycin resistant among coagulase-negative staphylococci (CoNS) isolates of different clinical samples in Al-Basrah governorate, Iraq.
The 28 CoNS, traditional techniques and the Vitek®2 system were used to identify the isolates. The disk diffusion technique was used to detect methicillin resistance and antibiotic sensitivity patterns via cefoxitin, gentamicin, ciprofloxacin, amikacin, teicoplanin, linezolid, doxycycline and vancomycin disks. Erythromycin and clindamycin antibiotic disks was used to detect the inducible and constitutive clindamycin resistance as well as a D-test according to CLSI guidelines.
Among 28 CoNS isolated, the
11(39.29%),
7(25 %),
4(14.29%) and
3 (10.71%) wer susceptibility testing in hospital and private clinical laboratories.
Multiple organ dysfunctions have been linked to exposure to polycyclic aromatic hydrocarbons (PAH) and oxidative stress (OS), oxidative DNA damage, and inflammatory response to PAH have been implicated. The biomarkers of OS (malondialdehyde (MDA), total plasma peroxide (TPP), total antioxidant capacity (TAC), glutathione (GSH), nitric oxide (NO), oxidative stress index (OSI)); 8-hydroxy-2-deoxyguanosine (8-OHdG)); tumor necrosis factor-alpha (TNF-α)); 1-hydroxy pyrene (1-HOP)), serum and urine creatinine, uric acid (UA), estimated glomerular filtration rate (eGFR) and peak expiratory flow rate (PEFR) were assessed in barbecue makers.
One hundred barbecue makers and 50 controls were enrolled into the study. Serum and urine creatinine, UA, TAC, MDA, GSH, NO and TPP were estimated by colorimetry, 8-OHdG and TNF-α by ELISA, PEFR using peak flow meter, 1-HOP by HPLC, eGFR and OSI by calculation.
Barbecue makers had lower TAC, PEFR, and higher TNF-α and OS compared to controls (p<0.05). Higher TNF-α, lipid peroxidation, and lower antioxidants were observed in barbecue makers who had worked for >5years compared to <5years (p <0.05). Increasing number of working hours was associated with higher NO, lipid peroxidation, OS and lower antioxidants in barbecue makers (p <0.05). Positive associations were observed between 1-HOP and TPP (r=0.570, p=0.000), OSI (r=0.299, p=0.035) and negative association between TAC and TNF-α (r=-0.209, p=0.037), MDA (r=-0.265, p=0.008) in barbecue makers.
Increased lipid peroxidation, OS, inflammation and depressed antioxidants and lung function observed in barbecue makers suggest increased risk of chronic lung conditions which may be associated with exposure to PAH in barbecue fumes.

Prostate cancer is known as one of the most prevalent health disorders in the male population globally. The aim of the current study was to evaluate the effects of separate and concomitant use of MK-2206 and salinomycin on prostate cancer cell line.
The antitumor potential of separate and concomitant use of MK-2206 and salinomycin was evaluated in a panel of prostate cancer cell line (PC-3). To get insights into the underlying mechanism of action, different assays including the rate of apoptosis, cell viability, and gene expression were performed in treated prostate cancer cells.
A significant reduction was detected in the viability percentage of prostate cancer cells (p< 0.001) and the rate of Akt expression (p< 0.001) in all salinomycin, MK-2206, and salinomycin+MK-2206 groups compared to the negative control group. Furthermore, in comparison with the negative control group, there was a notable increase in both the rate of Bad expression (p< 0.001) and prostate cancer cells apoptosis after salinomycin, MK-2206, and salinomycin+MK-2206 treatments. Moreover, the concomitant use of salinomycin+MK-2206 revealed synergistic improvements regarding the viability of prostate cancer cells and the rate of the Akt and Bad expressions compared to the separate administration of salinomycin and MK-2206 (all p< 0.05).
The findings of the present study may contribute to improving the efficacy of the therapies regarding the management of prostate cancer and providing a beneficial strategy in clinical trials.

The aim of present study is to asset the IL-2 promoter gene (SNP -475) as a candidate gene for multiple sclerosis (MS) susceptibility.
This study included 70 patients with relapsing - remitting multiple sclerosis (RRMS) and 50 healthy controls. Following the extraction of genomic DNA from peripheral blood, frequency of genotypes and alleles of SNP -475 was calculated using Restriction fragment length polymorphism-polymer chain reaction (RFLP-PCR) and then the results were analyzed statistically.
The results revealed the unusual ratio for the heterozygous (AT) was 1.6972 indicating that heterozygous patients were at higher risk of multiple sclerosis than wild homozygous (AA), and homomutant (TT). The results show protective role for - 475 IL-2 promoter among individuals with multiple sclerosis, (O.R 0.4872; C.I. 95% 0.1617- 1.4680) and (O.R 0.9275; C.I. 95% 0.2476 - 3.4745) for both AA and TT genotypes, respectively.
Our results showed that in this population of Iraqi patients, the AT genotype / A allele of -475 IL-2 promoter gene SNP may include attributed factors for MS predisposition.

ATP-binding cassette membrane transporter G2 (ABCG2) gene is one of transporter family and well characterized for their association with chemoresistance. Promoter methylation is a mechanism for regulation of gene expression. O6-Methyl guanine DNA methyl transferase (MGMT) gene plays a fundamental role in DNA repair. MGMT has the ability to remove alkyl adducts from DNA at the O6 position of guanine. Alkylating agents exert their function through adding these alkyls adducts to DNA leading to cell death unless it is repaired by MGMT. MGMT promoter was found to be methylated in several malignancies. The aim of the present work is to study the relation of MGMT and ABCG2 promoter methylation status in advanced breast cancer patients to response to cyclophosphamide-doxorubicin (AC) based therapeutic regime.
This retrospective study included Forty-two female patients with advanced breast cancer assessed before receiving chemotherapy and after the completion of regimens. They were grouped into responders and non-responders according to RECIST criteria. Methylation analysis of MGMT and ABCG2 genes were performed on breast cancer tissues.
MGMT promoter was methylated in 40.5% of the cases. ABCG2 promoter was methylated in 14.3% of cases. There was no statistically significant association between MGMT and ABCG2 promoter methylation status and clinicopathological parameters. There was statistically significant association between methylation status of both promoters and response to AC when followed by Taxane.
Methylation of MGMT and ABCG2 promoters combined could be a potential predictive factor for response to cyclophosphamide-doxorubicin based therapeutic regime.

The contribution of neutrophils is still indistinct in the inflammatory response of bronchial asthma (BAs). Myeloperoxidase (MPO) is an enzyme released from the primary azurophilic granules of the neutrophils. The study aimed to evaluate the levels of serum MPO as a biomarker for the assessment of the level of asthma control.
The study participants included 94 asthmatic patients and 86 healthy controls. The identification of asthma severity had assessed using the Global Initiative for Asthma guidelines. Asthmatic adults had divided into three groups Good (n= 22), partial (n= 30), and poor control (n= 44). Also, patients have been divided again into two groups (treated and untreated) for BAs.
The predicted FEV1% and the peak expiratory flow (PEF/L) of all participants had verified by spirometry. The mean patients' age was 31.9±15.1 year, with a predominance of females. The mean asthma duration was 10.5±8.6 years. Mean spirometric parameters (FEV1 and PEF) were significantly lower among the patients (0.00). Significant higher MPO levels had observed among BAs patients (p-0.00). The MPO levels have not differed significantly with asthma levels and had significant differences with the history of treatment. There was a nonsignificant negative correlation between the mean MPO levels and the spirometry variables among the patients. ROC curves revealed a sensitivity, specificity, accuracy for MPO (80.9%, 72.1%, and 84.3%), respectively to predict asthmatic severity.
There were significantly higher MPO levels compared to healthy controls. Levels of serum MPO had a non-significant positive correlation with levels of asthma control, but a negative non-significant correlation with spirometric results.
