Neuroscientists Are Also Capable of Incoherent Arguments Against Cryonics

The objective is to preserve the fine structure of neural tissue and nerve cell connections that encode the data of the mind. Provided that is stored successfully, then foreseeable forms of technology will in the future enable restoration and repair of this tissue. Early cryonics involved straight freezing, which wrecks tissue due to ice crystal formation. Modern cryonics aims for as-complete-as-possible vitrification via cryoprotectants, a process that suppresses ice crystal formation. There is ample evidence based on present theories of neural data encoding to believe that the necessary information is being preserved, albeit not the final absolute proof that many demand. One has to be cautious of ascribing too much weight to the discussions of scientists who step beyond their fields; expertise in one area doesn't translate to the pronouncement of scripture for all areas. Indeed, if the error rates of scientific papers are anything to go by, one should think that a scientist's expertise enables them to be reasonably correct in their own specialty about half the time, and that after the expenditure of a great deal of work, collaboration, thought, and error-checking. Advancing the front lines of science is a challenging endeavor. For the purposes of the two articles I'll point out here, attacking and defending the scientific basis for cryonics, the boundaries of specialty and knowledge are such that a neurobiologist doesn't necessarily have the expertise in cryobiology to off...

Authors: Wang Y, Zhang B, Gao G, Zhang Y, Xia Q Abstract Guanine nucleotide exchange factor T (GEFT), a member of the Rho guanine nucleotide exchange factor family, is expressed in a variety of tumors. In the present study, the expression and clinical significance of GEFT in malignant digestive tract tumors was assessed. Tumor and adjacent control samples from 180 patients were tested. Positive GEFT expression rates were 80, 83.33 and 86.67% in esophageal squamous carcinoma (ESCC), gastric carcinoma (GC) and colorectal cancer (CRC), respectively. GEFT expression was associated with diffuse type carcinoma according ...

Publication date: Available online 17 October 2019Source: Neuroscience LettersAuthor(s): Adrianne Eve Scovil Watson, Kara Goodkey, Tim Footz, Anastassia VoronovaAbstractOligodendrocyte and neural precursor cells (OPCs and NPCs, respectively) in the central nervous system (CNS) have diverse roles in development and homeostasis. During development, precursors build the CNS. In adulthood, they maintain their ability to proliferate and generate differentiated progeny, indicating their tremendous potential to regenerate and repair injured or degenerated CNS. How can we utilize this capability? Cross-talk between neurons and OPC...

ConclusionsThese results demonstrate the practical utility of HSI for the real-time detection of cerebral ischemia in rats. By providing rapid assessment of brain tissue perfusion, HSI may help doctors recognize ischemic regions quickly and precisely during surgery as well as have great utility in the experimental process.

CONCLUSIONS: This study described the characteristic of CG, number of its nerve root and some measurements relevant to intraorbital procedures in Asian population. Moreover, a new parameter was the distance between CG and scleral insertion of the lateral rectus muscle. This parameter should be considered when performing operation involved the lateral rectus muscle and BTX-A injection to lateral rectus muscle to reduce CG injury.

Authors: Manabe H, Tezuka F, Yamashita K, Sugiura K, Ishihama Y, Takata Y, Sakai T, Maeda T, Sairyo K Abstract For full-endoscopic lumbar discectomy, operating costs are also important because expensive equipment are necessary. We surveyed the operating costs of surgical equipment necessary for full-endoscopic surgery together with surgical procedure reimbursement fees. A total of 295 cases of full-endoscopic surgery via a transforaminal approach were retrospectively analyzed. We calculated the frequency of damage and the unit purchase price of devices such as endoscopes, and surgical instruments such as grasping f...

Mohamed, Nagwa El-Badri, Amr ZaherAbstractStem cell therapy using bone marrow derived or mesenchymal stem cells has become a popular option for cardiovascular disease treatment, however the administration of embryonic stem cells has been mostly experimental. Remarkably, most of these ongoing clinical trials involve adult patients, but little is known regarding the safety and efficacy of stem cell therapy in newborns and children battling congenital heart diseases. Furthermore, cell delivery methods involve the administration of stem c...
