Although β-carotene is known for its anti-carcinogenic and antioxidant properties, a few recent epidemiological and experimental evidence show that at higher concentration it acts as pro-oxidant and induces cancer. Since the global burden of breast cancer exceeds all other types of cancer, and its incidence rates is also in increasing trend, the present study attempted to evaluate the anti-cancer molecular mechanism of β-carotene (at 1 µM concentration) isolated from Spinacia oleracea in human breast cancer (MCF-7) cells...

BACKGROUND: Cancers from lung and esophagus are the leading causes of cancer-related deaths in China and share many similarities in terms of histological type, risk factors and genetic variants. Recent genome-wide association studies (GWAS) in Chinese esophageal cancer patients have demonstrated six high-risk candidate single nucleotide polymorphisms (SNPs). Thus, the present study aimed to determine the risk of these SNPs predisposing to lung cancer in Chinese population. METHODS: A total of 1170 lung cancer patients and 1530 normal subjects were enrolled in this study from high-incidence areas for esophageal cancer in Henan, northern China...

BACKGROUND: Lung cancer is one of the most serious disease and the incidence of non-small cell lung cancer (NSCLC) is the highest in lung cancer. The main reason for the failure of chemotherapy is the tolerance to cisplatin. Transcriptional regulator SOX4 plays an important role in the occurrence and development of many tumors, and regulates Wnt signaling pathway by regulating the expression of β-catenin. We aimed to investigate the role of SOX4 on cisplatin-resistance in NSCLC cell A549 cell...

In 2012 the Israel Police DNA Casework laboratory adopted the 16 STR PowerPlex(®) ESI kit for routine use. The Promega Company updated this kit and developed the PowerPlex(®) ESI 16 Fast System in which all autosomal primer pairs remained identical to the original set, except at the amelogenin site. The master mix was improved and optimized which allowed for direct, faster and more robust amplification. Prior to implementing the PowerPlex(®) ESI 16 Fast System in our lab, we conducted a preliminary assay where 213 casework samples were amplified using the new kit...

BACKGROUND: Healthcare and other front-line workers are at particular risk of infection with Ebola virus (EBOV). Despite the large-scale deployment of international responders, few cases of Ebola virus disease have been diagnosed in this group. Since asymptomatic or pauci-symptomatic infection has been described, it is plausible that infections have occurred in healthcare workers but have escaped being diagnosed. We aimed to assess the prevalence of asymptomatic or pauci-symptomatic infection, and of exposure events, among returned responders to the West African Ebola epidemic 2014-2016...
