The epidermal growth factor receptor (EGFR) autocrine pathway contributes to a number of processes important to cancer development and progression, including cell proliferation, apoptosis, angiogenesis, and metastatic spread. The critical role the EGFR plays in cancer has led to an extensive search for selective inhibitors of the EGFR signaling pathway. The results of a large body of preclinica...

The hypothesis that oral supplementation with virgin coconut oil (Cocos nucifera L.) and exercise training would improve impaired baroreflex sensitivity (BRS) and reduce oxidative stress in spontaneously hypertensive rats (SHR) was tested. Adult male SHR and Wistar Kyoto rats (WKY) were divided into 5 groups: WKY + saline (n = 8); SHR + saline (n = 8); SHR + coconut oil (2 mL·day(-1), n = 8); S...

Background and Purpose—Stent-assisted coiling has expanded the treatment of intracranial aneurysms, but the rates of procedure-related neurological complications and the incidence of angiographic aneurysm recurrence of this novel treatment are not yet well known. We present our experience with stent-assisted coiling with special emphasis on procedure-related neurological complications and incid...

BACKGROUND In Ethiopia, there is a substantial mismatch between need and supply of corneal transplant. Although corneal transplantation service is affected by various factors, willingness to donate eyes is an essential indicator of its availability, accessibility, and acceptability. Therefore, this study aimed to determine the magnitude of willingness to donate eyes and its associated factors, ...

The calibration of radiocarbon dates by means of a master calibration curve has been invaluable to Earth, environmental and archeological sciences, but the fundamental reason for calibration is that atmospheric radiocarbon content varies because of changes in upper atmosphere production and global carbon cycling. Improved instrumentation has contributed to high-resolution (interannual) radiocar...

GW572016 (Lapatinib) is a tyrosine kinase inhibitor in clinical development for cancer that is a potent dual inhibitor of epidermal growth factor receptor (EGFR, ErbB-1) and ErbB-2. We determined the crystal structure of EGFR bound to GW572016. The compound is bound to an inactive-like conformation of EGFR that is very different from the active-like structure bound by the selective EGFR inhibit...

Inks and toners used for printing contain materials, such as polyester, with strong triboelectric properties to enhance the binding effects, making wastepaper, magazines newspapers, good candidates materials. Herein, high-output power nanogenerators (TENGs) that utilize wastepaper layers (wastepaper-based (WP–TENGs)) are reported. Journal paper office copy wastes investigated. The results show ...

BACKGROUND Tetracycline regulated ectopic gene expression is a widely used tool to study gene function. However, the tetracycline regulator (tetR) itself has been reported to cause certain phenotypic changes in mammalian cells. We, therefore, asked whether human myeloid U937 cells expressing the tetR in an autoregulated manner would exhibit alterations in gene expression upon removal of tetracy...
