Focal adhesion kinase: a potential target in cancer therapy

Focal adhesion kinase (FAK) is a non-receptor tyrosine kinase that plays an important role in signal transduction pathways that are initiated at sites of integrin-mediated cell adhesions and by growth factor receptors. FAK is a key regulator of survival, proliferation, migration and invasion: processes that are all involved in the development and progression of cancer. FAK is also linked to oncogenes at both a biochemical and functional level. Moreover, overexpression and/or increased activity of FAK is common in a wide variety of human cancers, implicating a role for FAK in carcinogenesis. Given the important role of FAK in a large number of processes involved in tumorigenesis, metastasis and survival signalling FAK should be regarded as a potential target in the development of anti-cancer drugs. Therefore, selective inhibitors of FAK need to be developed. Combination of these selective FAK inhibitors with cytotoxic agents could be a very promising anti-cancer therapy.

GENE TRANSFER INTO PORCINE MYOCARDIUM VIA PERICARDIAL CAVITY BY HOMEMADE EASY PUNCTURE DEVICEA

Objective To explore the feasibility and safety of gene transfer into porcine myocardium via the pericardial cavity by a homemade easy device.Methods Replication-deficient recombinant adenoviral vector carrying LacZ report gene (Ad-LacZ) was constructed by the calcium phosphate precipitation method. Twelve healthy Chinese mini-swine were randomly divided into experimental group (n = 6) and control group (n =6). Acute myocardial infarction (AMI) model was established by balloon occlusion of the distal part of D[ branch of left anterior descending (LAD) artery, at the same time the intra-pericardial cavity injections were performed through the small incision of the abdominal wall below the xyphoid appendix using a homemade device. Then gene transfer was performed using a central venous catheter. The pericardium was pre-treated with injection of a mixture of collagenase (1 200 U) and hyaluronidase (3 000 U) in both groups. Then 2. 0 × 109 plaque formation unit (PFU) Ad-LacZ was injected into the pericardial cavity in experimental group, while 1 mL of normal saline was injected in the control group. The p-galactosidase activity detection and X-gal staining of the ischemic myocardium were performed on the 3rd, 7th, and 28th day after injection.Results The LAD artery was occluded completely and infarction and ischemia were detected by histological assessment In experimental group, the X-gal staining positive cells and (3-galactosidase activity quantification were detectable on the 3rd day after injection, increased markedly on the 7th day, and then declined on the 28th day. The transfer efficiencies indicated by the positive myocardial cells were 16. 7% , 45. 6% , 22. 8% on the 3rd, 7th, 28th day, respectively. In control group, no positive cells and (3-galactosidase activity were observed.Conclusion Adenovirus can be transferred into ischemic myocardium and express target gene in the AMI model for four weeks with the homemade easy device via pericardial cavity pretreated by collagenase and hyaluronidase.     

Neurodevelopmental disorder associated with prenatal exposure to alcohol (ND-PAE): A proposed diagnostic method of capturing the neurocognitive phenotype of FASD

Neurobehavioral Disorder associated with Prenatal Alcohol Exposure (ND-PAE) was proposed as a diagnostic formulation intended to capture the range of mental health problems occurring in alcohol-affected individuals with a history of prenatal alcohol exposure. The proposed criteria for the disorder are reviewed as well as various factors considered in the development of the disorder and its associated criteria. The taxonomic research related to the disorder is reviewed with preliminary analyses indicating that clinicians are readily able to agree when applying the diagnostic criteria but that the adaptive functioning criteria may need to be modified to expand its coverage of alcohol-affected individuals and to aid in discriminating these individuals from others not alcohol-affected. Finally, the challenges with translating the diagnosis into European medical and mental healthcare systems are discussed and recommendations for facilitating implementation are made.

Four‐dimensional computed tomography (4DCT): A review of the current status and applications

The applications of conventional computed tomography (CT) have been widely researched and implemented in clinical practice. A recent technological innovation in the field of CT is the emergence of four‐dimensional computed tomography (4DCT), where a three‐dimensional computed tomography volume containing a moving structure is imaged over a period of time, creating a dynamic volume data set. 4DCT has previously been mainly utilised in the setting of radiation therapy planning, but with the development of wide field of view CT, 4DCT has opened major avenues in the diagnostic arena. The aim of this study is to provide a comprehensive narrative review of the literature regarding the current clinical applications of 4DCT. The applications reviewed include both routine diagnostic usage as well as an appraisal of the current research literature. A systematic review of the studies related to 4DCT was conducted. The Medline database was searched using the MeSH subject heading ‘Four‐Dimensional Computed Tomography’. After excluding non‐human and non‐English papers, 2598 articles were found. Further exclusion criteria were applied, including date range (since wide field of view CT was introduced in 2007), and exclusion of technical/engineering/physics papers. Further filtration of papers included identification of Review papers. This process yielded 67 papers. Of these, exclusion of papers not specifically discussing 4DCT (cone beam, 4D models) yielded 38 papers. As part of the review, the technique for 4DCT is described, with perspectives as to how it has evolved and its benefits in different clinical indications.
