Old drugs, new tricks: Medications approved for other uses also have antibiotic action

(University of Illinois at Urbana-Champaign) A number of drugs already approved to treat parasitic infections, cancers, infertility and other conditions also show promise as antibiotic agents against staph and tuberculosis infections, according to a new study by University of Illinois chemists and collaborators. Because these agents act against multiple targets within the bacteria, it may be harder for bacteria to develop resistance.

Cancer is a complex disease with abnormal cell growth control which is hallmarked by chromosome misalignment and consequently genomic instability. Mitosis is a well-known target for chemotherapy as taxol and colchicines inhibit tumor cell division by inhibiting mitotic spindle plasticity. Accumulating evidence has revealed that the Centromere-associated protein E (CENP-E) is expr...

Therefore, it is significant to reveal the principle of breaking the subtle homeostasis of cell cycle and sustaining chronic proliferation of cancer cells.Main methodsThe expression of TNNT1 was examined by qPCR and western blotting. The effect of TNNT1 on cell proliferation was detected by...

However, in order to curtail the computational complexity and augment the accuracy of cancer classification, it is essential to sift the vast microarray data for the informative genes. In this paper, Thresholding and Ratio methods are presented, individually as well as conjointly (hybrid method) to choose optimal gene subset from the...

We present a quantitative study of the performance of two automatic methods for the early detection of ovarian cancer that can exploit longitudinal measurements of multiple biomarkers. The study is carried out for a subset of the data collected in the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS). We use statistical analysis techniques, such as the area under the Receiver Operating Characteristic (ROC) curve, for evaluating the performance of two techniques that aim at the classification of subjects as either healthy or suffering from the disease using time-series of multiple biomarkers as inputs. The first ...

Nesfatin-1 is a novel peptide with antioxidant, anti-inflammatory and anti-apoptotic properties. In the present study, we aimed to investigate the putative beneficial effects of nesfatin-1 on oxidative injury and impaired testicular function induced by testis torsion.

In conclusion, these results suggest the potential preventive effects of the five phytochemicals on the promoting effect of Ni on human lung cancer cell invasion. In addition, the preventive effects are associated with downregulation of the TLR4/NF-κB signaling pathway, especially for quercetin and chrysin.

However, only a few researches about its detection methods have been reported because PARP-1 and its catalyzed product poly(ADP-ribose) polymer (PAR) are lack of optical or electrochemical activity. Herein, a convenient fluorescence “turn-off-on” nanosensor based on cationic conjugat...

However, the presence of abnormally high levels of FA are often associated with a variety of disease pathologies, including chronic liver, heart and neurodegenerative diseases, in addition to diabetes and various cancers. Hence, a more efficient tool for monitoring FA in...

Its quantification in peripheral blood could provide an important contribution to diagnostics and patient follow-up. In this work an electrochemical molecularly imprinted polymer (MIP) sensor for the quantification of HER2-ECD was developed. The MIP was electropolymerized by cyclic voltammetry usin...
