Luis E Savastano, Neeraj Chaudhary, Carlos Murga-Zamalloa, Michael Wang, Thomas Wang, B Gregory Thompson
BACKGROUND: Angioscopy - or endovascular endoscopy - is a catheter-based technique employing a flexible fiberoptic angioscope to directly visualize arterial lumen. Poor resolution and excessive stiffness of pre-existent angioscopes limited their use clinically. Recent advances resulted in novel fused optical fiber bundle angioscopes with improved flexibility and imaging resolution. Use of these devices in endovascular neurosurgery is still largely unexplored. OBJECTIVE: To evaluate image quality and feasibility of optical angioscopes for diagnostic and interventional neuro-angioscopy in carotid arteries of human cadavers...

BACKGROUND: The stereotactic accuracy of intraoperative imaging is critical to clinical outcome, particularly in "asleep" deep brain stimulation (DBS) surgery that typically forgoes neurophysiological techniques. Different intraoperative imaging modalities and associated accuracies have been reported, including magnetic resonance imaging (MRI), computed tomography (CT), and O-arm. OBJECTIVE: To analyze intraoperative O-arm imaging accuracy and to evaluate the utility of microelectrode mapping...

Glaucoma leads to blindness but there are diagnostic and therapeutic developments that aid ophthalmologists in the improved mangement of the disease compared to the past. Known risk factors such as age, myopia, dark pigmented skin, genetics, and elevated intraocular pressure play an important role for the individual patient's prognosis, and many yet unknown or not sufficiently investigated risk factors come along. The structured examination of the optic nerve head is crucial for the clincial diagnosis by the ophthalmologist...

ALK translocation is the 3rd most frequent genetic aberration in lung adenocarcinoma, and several inhibitors are now clinically available in first and second line settings. Accordingly, molecular diagnostics of ALK-positive lung cancer is very important and can be done with the rational combination of several methods. All international recommendations suggest that, except for cytological samples, screening technology for ALK-positive tumors is immunohistochemistry using a validated test. It is highly recommended that in case of ALK protein positive samples gene translocation must be confirmed by fluorescent in situ hybridization (FISH)...

Patients with cancer present a number of different difficulties that adversely affect their health care and recovery (e.g. poor communication with physicians, lack of knowledge about their illness and its management, financial problems). Furthermore, mental health problems, such as distress, depression and anxiety, are common amongst patients with cancer. These mental health problems are additional contributors to functional impairment in carrying out family, work, and other social roles, poor adherence to medical treatments, and adverse medical outcomes...

The evolution of medicine is noticeable in most therapeutic areas, the worse the current therapeutic result, the more quick the improvement. This is especially true in such areas that require substantial social resources, namely oncology, diabetology and CNS diseases. Pain is not a disease, it is a symptom. Pain is one of the most important components of human suffering thus it deserves special attention. In recent years new formulations of old medicines were introduced rather than new medicines. Maybe ziconitide is the last pain killer with new mechanism of action which was approved by FDA in 2004...

Much laboratory work has been carried out to determine the gene regulatory network (GRN) that results in plant cells becoming flowers instead of leaves. However, this also involves the spatial distribution of different cell types, and poses the question of whether alternative networks could produce the same set of observed results. This issue has been addressed here through a survey of the published intercellular distribution of expressed regulatory genes and techniques both developed and applied to Boolean network models...

The ability to isolate specific brain regions of interest can be impeded in tissue disassociation techniques that do not preserve their spatial distribution. Such techniques also potentially skew gene expression analysis because the process itself can alter expression patterns in individual cells. Here we describe a laser capture microdissection (LCM) method to selectively collect specific brain regions affected by traumatic brain injury (TBI) by using a modified Nissl (cresyl violet) staining protocol and the guidance of a rat brain atlas...
