Chemotherapy, using anthracycline-based chemotherapeutic agents in neoadjuvant settings, has been introduced as a promising new therapeutic option for treatment of invasive breast cancer. Set apart from conventional anthracycline regimens such as epirubicin, pegylated liposomal doxorubicin (Lipo-Dox®, PLD) was introduced for providing a justifiable treatment effect, while offering a favorable toxicity profile for breast cancer patients in a metastatic setting. However, the efficacy of PLD in neoadjuvant settings for breast cancer patients has not yet been sufficiently reported. This study aims to investigate the efficacy of PLD-based neoadjuvant chemotherapy in breast cancer patients using a retrospective matched case-control study. A total of 183 PLD cases and 183 epirubicin-based controls were included after a 1 : 1 ratio case-control matching procedure was held, according to the matching criteria. These criteria included the patient's preoperative clinical stage, molecular subtype, chemotherapy regimen with taxanes prior to surgery, and histological grade. All data were collected according to an institutional review board approved protocol. The study results reported that the PLD and epirubicin groups both obtained similar outcomes in pathologic complete response (pCR), recurrence, and overall survival rate with no statistically significant differences.

Antibiotics have been used to treat <i>S. aureus</i> infections. However, there has been increased mortality associated with drug-resistant strains of <i>S. aureus</i>. Extracellular proteases have been implicated to be responsible for the transition of <i>S. aureus</i> from an adhesive pathogen to an invasive pathogen. The development of resistant strains has necessitated the search for new sources of drugs. Plants have been traditionally used as sources of therapeutic molecules. The objective of this study was to determine the effect of tormentic acid and the extracts from <i>Callistemon citrinus</i> on the production of extracellular proteases by <i>S. aureus</i>. The broth microdilution antibacterial susceptibility assay was used to determine the antibacterial effects of tormentic acid and the extracts on <i>S. aureus</i>. Both extracts showed a minimum inhibitory concentration (MIC) value of 50 <i>μ</i>g/ml. The water : ethanol (50 : 50) and the dichloromethane : methanol (50 : 50) extracts were found to be bactericidal against S. <i>aureus</i> at a concentration of 100 <i>μ</i>g/ml and 50 <i>μ</i>g/ml, respectively. The effect of tormentic acid and extracts on extracellular protease production was investigated using the protease assay. A zone of proteolytic activity (Pr) was measured as the ratio of the diameter of the colony to the total diameter of colony plus zone of hydrolysis. The extracts reduced the production of extracellular proteases, while tormentic acid completely inhibited the production of extracellular proteases by <i>S. aureus</i>. The Pr value for tormentic acid was found to be 1. The Pr values of the dichloromethane : methanol extract and the water : ethanol extract were 0.92 and 0.84, respectively.

Thus, to investigate the role of the extracts in the coagulation of milk and their health threats, the milk-clotting activity, phytochemical screening tests, antimicrobial activities by the agar well diffusion method, and heavy metal content by ICP-OES technique were determined. Accordingly, both <i>Ficus carica</i> and <i>Solanum incanum</i> were found to possess phenolics, saponins, and tannins. Likewise, positive tests for flavonoid in <i>Ficus carica</i> and alkaloid in <i>Solanum incanum</i> were observed. However, no terpenoids, glycosides, and oxalates were detected in the plants. Moreover, the crude and concentrated enzyme extracts of the plants exhibited clotting activity. In this regard, the enzyme extracts of <i>Ficus carica</i> were superior with the highest clotting activity of 1.20 U. On the other hand, ethanol and chloroform extracts of the samples showed inhibition zones against all tested microorganisms except their chloroform extract which did not exhibit inhibition against <i>Escherichia coli</i> and <i>Aspergillus niger</i>. Likewise, the metals Cr, Cd, Mn, Cu, and Fe were detected in the plant samples, with the Mn content of 3.67 ± 0.10 mg per kg of dry weight of the plant in <i>Ficus carica</i> being the highest. Indeed, the level of the heavy metal contents is considerably lower than those maximum permissible limits set by international standards. On the other hand, no Pb and Zn were detected in the plant samples. Therefore, the higher clotting activity of the enzyme extracts was an indicator that enzymes, rather than other phytochemicals, are the most probable agents responsible for the milk-clotting ability of the plants, resulting in the formation of cheese. Furthermore, the growth inhibition to most of the test microbes is a manifestation that bacterial fermentation is not a means of clotting the milk as bacteria introduced to the milk would be killed by the sample extracts. Moreover, the use of the plants in the coagulation process would not pose health threats as far as oxalate and metal toxicity is concerned.</p>","PeriodicalId":8826,"journal":{"name":"Biochemistry Research International","volume":"2020 ","pages":"9874949"},"PeriodicalIF":3.0,"publicationDate":"2020-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2020/9874949","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37861200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
