Mutations in rpoB and katG genes of multidrug resistant mycobacterium tuberculosis undetectable using genotyping diagnostic methods.

Tuberculosis remains the leading causes of death worldwide with frequencies of mutations in rifampicin and isoniazid resistant Mycobacterium tuberculosis isolates varying according to geographical location. There is limited information in Zimbabwe on specific antibiotic resistance gene mutation patterns in MTB and hence, increased rate of discordant results and mortality due to inappropriate antibiotic prescriptions. The rpoB and katG genes molecular markers are used for detecting rifampicin and isoniazid resistance respectively. Some mutations within these gene sequences are associated with drug resistance as they directly alter gene function. The objectives of this research was to determine the drug resistance profiles in M. tuberculosis isolates that are phenotypically resistant but not detected by the GeneXpert and MTBDRplus kit and also to detect mutations in the rpoB and katG genes which are not detected by the Hain Genotype MTBDRplus kit and GeneXpert diagnosis.

Attenuation of Sulfite-Induced Testicular Injury in Rats by Zingiber officinale Roscoe.

Sulfite salts, including sodium metabisulfte, are widely used as preservatives in foods and pharmaceutical agents. Previous studies suggest that oxidative stress may be an important mediator of testicular injury. The present study was designed to elucidate the effect of exposure to sodium metabisulfite by gavage without or with Zingiber officinale (ginger) extract on the rat testes. Thirty-two male Wistar rats were randomly divided into control, ginger-treated (500 mg/kg/day), sodium metabisulfite- (SMB-) treated (260 mg/kg/day), and SMB + ginger- (SZ-) treated groups. After 28 days, the rats were anesthetized by ether and, after laparotomy, blood was collected from the heart to determine testosterone level by the enzyme-linked immunosorbent assay (ELISA) kit. Then left testes and cauda epididymis of all animals were removed for histological examination and sperm analysis, and right testes were removed for assessing lipid peroxidation (indexed by malondialdehyde [MDA]) and antioxidant enzymes. The results showed that spermatogenesis, epididymal morphometry, and sperm parameters were affected by SMB. There was a significant increase in MDA level and a significant reduction in the activities of glutathione peroxidase (GPx), glutathione reductase (GR), and catalase (CAT) in the SMB-treated rats compared to the control. Ginger treatment of SMB-exposed rats significantly increased testosterone level and the number of different spermatogenic cells. The level of MDA reversed to the control levels and the activities of GPx and GR were significantly increased when SMB was coadministered with ginger extract. It is concluded that coadministration of ginger, through its antioxidant and androgenic properties, exerts a protective effect against SMB-induced testicular oxidative stress.

Degradation of Extracellular DNA by DNase1 Significantly Reduces Testicular Damage After Testicular Torsion in Rats.

To examine the effects of DNase1 treatment on testicular damage after testicular torsion (TT). It has been demonstrated that TT induces thrombus formation and that anticoagulation significantly reduces testicular damage after TT. It was hypothesized that these thrombi are dependent on neutrophil extracellular traps (NETs) and thus NETs disintegration would reduce testicular cell damage.

Proteomics investigation of OSCC-specific salivary biomarkers in a Hungarian population highlights the importance of identification of population-tailored biomarkers.

Oral squamous cell carcinoma (OSCC) accounting for about 90% of malignant oral lesions is the 6th most common malignancy worldwide. Diagnostic delay may contribute to dismal survival rate therefore, there is a need for developing specific and sensitive biomarkers to improve early detection. Hungarian population occupies the top places of statistics regarding OSCC incidence and mortality figures therefore, we aimed at finding potential salivary protein biomarkers suitable for the Hungarian population. In this study we investigated 14 proteins which were previously reported as significantly elevated in saliva of patients with OSCC. In case of IL-1α, IL-1β, IL-6, IL-8, TNF-α and VEGF a Luminex-based multiplex kit was utilized and the salivary concentrations were determined. In case of catalase, profilin-1, S100A9, CD59, galectin-3-bindig protein, CD44, thioredoxin and keratin-19, SRM-based targeted proteomic method was developed and the relative amount of the proteins was determined in the saliva of patients with OSCC and controls. After several rounds of optimization and using stable isotope-containing peptides, we developed an SRM-based method for rapid salivary protein detection. The validation of the selected potential biomarkers by ELISA revealed salivary protein S100A9 and IL-6 as useful protein biomarkers for OSCC detection improving the diagnostic accuracy for OSCC in the Hungarian population.A noninvasive diagnostic method to detect biomarkers useful for the early diagnosis of OSCC was developed. This can be an attractive strategy in screening saliva samples collected in a nation-wide multi-centric study in order to decrease morbidity, mortality, to enhance survival rate and to improve quality of life. The heterogeneity of protein biomarkers found in different ethnic groups presented in the literature highlights the importance of identification of population-tailored protein biomarkers.

[Inula Britannica flower total flavonoids reduces the apoptosis of aging bone marrow mesenchymal stem cells by anti-oxidation].

Objective To investigate the beneficial effect of Inula Britannica flower total flavonoids (IBFTF) on aging bone mesenchymal stem cell (BMSC) and its potential mechanism. Methods The aging BMSCs were induced by D-galactose, and then treated with 12.5, 25, 50 μg/mL IBFTF. The cell viability was detected by CCK-8 assay. The activity of catalase (CAT) and superoxide dismutase (SOD), the content of malondialdehyde (MDA) and reactive oxygen species (ROS) were measured by a commercial kit. The apoptosis was assessed by flow cytometry. The protein expressions of BAX, Bcl-2 and cleaved-caspase-3 (c-caspase-3) were determined by Western blotting. Results The cell viability and the activity of SOD and CAT in the aging group decreased significantly compared with the normal group, whereas different concentrations of IBFTF promoted the cell viability, and simultaneously increased the activity of SOD and CAT. The apoptosis, the ROS production, the content of MDA, BAX/Bcl-2 ratio and the protein expression of c-caspase-3 in the aging group increased obviously compared with the normal group. However, the treatment of different concentrations of IBFTF reduced the apoptosis, the ROS production, the content of MDA, BAX/Bcl-2 ratio and the protein expression of c-caspase-3. Conclusion IBFTF can attenuate the apoptosis of aging BMSCs by anti-oxidation.

Cardioprotective Effects of Malvidin Against Isoproterenol-Induced Myocardial Infarction in Rats: A Mechanistic Study.

BACKGROUND Malvidin (alvidin-3-glucoside) is a polyphenol that belongs to the class of natural anthocyanin, which is abundantly found in red wines, colored fruits, and the skin of red grapes. Therefore, the current investigation was intended to evaluate the effect of malvidin against myocardial infarction induced by isoproterenol in the rats. MATERIAL AND METHODS The cardioprotective effects was assessed by determining the effect of malvidin on the activities of endogenous antioxidants - catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH) - and on the levels of lipid peroxidation and serum marker enzymes. The serum levels of IL-6 and TNF-α were also determined using an enzyme-linked immunosorbent assay (ELISA) kit. RESULTS The present study demonstrated a significant cardioprotective effect of malvidin by restoring the defensive activities of endogenous antioxidants - catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH) - and by reducing the levels of lipid peroxidation and serum marker enzymes lactate dehydrogenase (LD) and creatine kinase (CK). Malvidin significantly ameliorated the histopathological changes and impaired mitochondria in the cardiac necrosis stimulated with isoproterenol. Additionally, the results also demonstrated that nuclear translocation of Nrf-2 and subsequent HO-1 expression might be associated with nuclear factor kappa B (NF-κB) pathway activation. CONCLUSIONS Our findings suggest that malvidin exerts cardioprotective effects that might be due to possible strong antioxidant and anti-inflammatory activities. Therefore, this study provides the basis for the development of malvidin as a safe and effective treatment of myocardial infarction.

Identification of a host cell protein impurity in therapeutic protein, P1.

Residual host cell proteins (HCPs) are process-related impurities present in biotherapeutics that can pose safety health risks to patients. An adequate control of HCP levels in the final product, and demonstration of HCP clearance throughout a product manufacturing process is critical for all biotherapeutic products. Developing effective downstream purification processes can be challenging as HCPs and product proteins may possess an affinity for each other or have similar physicochemical properties, resulting in co-purification. In the current study, we identified the presence of CHO-catalase subunit protein as an impurity present in purified P1 protein. This previously unreported HCP impurity, was detected in P1 protein generated in Chinese hamster ovary (CHO) cells. Purified drug substance samples contained elevated CHO HCP levels when measured using a commercial anti-CHO HCP Enzyme-Linked Immunosorbent Assay (ELISA) kit. This finding, prompted further characterization of the HCP profile using 1D and 2D gels/ western blots using an anti-human IgG antibody as well as a commercial anti-CHO HCP antibody (Cygnus 813) for the detection of host cell proteins. The CHO-catalase protein has been characterized using a combination approach of one-dimensional (1D) and two-dimensional (2D) gels and western blotting techniques, and the identity confirmed using liquid chromatography-mass spectrometry (LC-MS/MS) analysis. Western blot analyses using the anti-CHO HCP antibody detected a potential HCP band at ∼60 kDa and a pI of ∼8 in the purified P1 sample. The 60 kDa HCP band was excised from 1D SDS-PAGE gels and LC-MS/MS analysis identified it to be CHO-catalase subunit. The identity of catalase monomer was further confirmed by western blot analysis using a specific anti-catalase antibody.
