It is used in treating acute bacterial skin and skin structure infections, community acquired respiratory tract infections and methicillin-resistant <em>S.</em> <em>aureus</em> bacteremia. The main resistance mechanisms of bacteria to β-lactam antibiotics, including ceftaroline, are mutations in PBP2a, PBP3 and PBP4. Clinically significant resistance has been noted among both archived and newly-isolated strains in a laboratory test using serial passages. Ceftaroline-resistant strains have also been found in patients suffering from cystic fibrosis, ventilator-associated pneumonia and infectious endocarditis. Irresponsible antibiotic treatment using ceftaroline or other antibiotics (due to a possibility of a cross-resistance) can lead to the spread of ceftaroline resistance and, consequently, its loss of value.</p> <p><strong>DOI</strong>: <a href=""></a></p> Rafał Ślusarczyk Ada Bielejewska Arkadiusz Bociek Martyna Bociek ##submission.copyrightStatement## 2018-07-03 2018-07-03 8 3 112 120 Sodium fluoride: suggestive role in wound healing and cell proliferation with respect to regeneration <p>Sodium fluoride is a naturally occurring toxicant. The most common sources of sodium fluoride are municipal water, toothpastes etc. The ever increasing exposure to sodium fluoride may affect various physiological processes including regenerative capabilities. The characteristic events of regeneration include wound healing followed by cell proliferation and differentiation to replace the lost structure or tissue. Lower levels of sodium fluoride may be enhancing wound healing and cell proliferation but higher levels are detrimental for both these processes. Sodium fluoride affects wound healing by altering the expression of various proteins like fibroblast growth factors 2 and 7, Twist1 protein, matrix metalloproteinases 2 and 7, bone morphogenetic protein 7, Bcl-2, p53 etc. Sodium fluoride also influences cell division, migration and matrix synthesis by regulating the expression of bone morphogenetic proteins 2 and 3, alkaline phosphatases etc. which are markers of cell proliferation. Excessive fluoride produces oxidative stress in the cells and leads to conditions like apoptosis, cell cycle arrest and even necrosis. Thus, high levels of sodium fluoride hamper the process of cell proliferation and induce apoptosis via caspase and JNK-mediated pathway. The aim of this review is to understand the role sodium fluoride plays during wound healing and cell proliferation and its correlation with regenerative capabilities in organisms.</p> <p><strong>DOI</strong>: <a href=""></a></p> Meena Yadav ##submission.copyrightStatement## 2018-07-15 2018-07-15 8 3 131 137 Profile of major and emerging mycotoxins in sesame and soybean grains in the Federal Capital Territory, Abuja, Nigeria <p>The spectrum of major and emerging mycotoxins in sesame and soybean grains from the six zones of the Federal Capital Territory (FCT), Abuja, Nigeria was determined using Liquid Chromatography/Tandem Mass Spectrometry (LC-MS/MS). A total of 47 samples (24 sesame and 23 soybean were collected from farmers’ stores. Seven regulated mycotoxins in sesame and five in soybean including aflatoxin B<sub>1</sub> (AFB<sub>1</sub>), aflatoxin B<sub>2 </sub>(AFB<sub>2)</sub> and fumonisin B<sub>1 </sub>(FB<sub>1</sub>) were detected. However, concentrations were generally lower than regulatory limits set in the EU for raw grains with the exception of ochratoxin A (OTA) exhibiting a maximum concentration level of 23.1 µg kg<sup>-1</sup> in one of the soybean samples. This is the first report concerning the contamination of sesame and soybean in Abuja, FCT-Nigeria with the emerging&nbsp;mycotoxins addressed by recent European Food Safety Authority (EFSA) opinion papers totalling 10 in number. These include beauvericin (BEA), moniliformin (MON), sterigmatocystin (STE), altertoxin-I (ATX-I), alternariol (AOH), alternariol methylether (AME) though at relatively low µg kg<sup>-1&nbsp;</sup>range. This preliminary data indicate that sesame and soybean might be relatively safe commodities in view of the profile of mycotoxins.</p> <p><strong>DOI</strong>: <a href=""></a></p> Stephen O.
