You know how sometimes you just cant resist collecting old hardware, so you promise yourself that you will get around to working on it some day? [Danny] actually followed through on one of those promises after discovering an old Radio Shack TRS-80 TP-10 thermal printer in one of his boxes of old gear. It looks similar to a receipt printer you might see printing receipts at any brick and mortar store today. The original printer worked well enough, but [Danny] wasnt satisfied with its 32 character per line limitation. He also wanted to be able to print more complex graphics. To accomplish this goal, he realized he was going to have to give this printer a brain transplant.. First, [Danny] wanted to find new paper for the printer. He only had one half of a roll left and it was 30 years old. He quickly realized that he could buy thermal paper for fax machines, but it would be too wide at 8.5 inches. Luckily, he was able to use a neighbors saw to cut the paper down to the right size. After a test ...

This study reports the long-term safety, motor, cognitive and psychiatric effects of bilateral fetal striatal allotransplants in five patients with mild to moderate HD, in comparison with a reference group of 12 patients from the same cohort who were similarly suitable for transplantation but not selected for surgery, but were followed in an identical way.. There were no significant differences in any of the measures chosen when comparing patients with transplants with this reference cohort at baseline and followed-up for up to 10 years postsurgery, using identical protocols of assessment. In small open label studies with multiple outcome measures, it is tempting to focus on apparent improvements in individual patients on particular tests. However, although such encouraging signs could be identified in the present five patients, the changes were in all cases small; similar short-term fluctuations could be identified in control patients of the reference group; and there were no statistically ...

The repairs were much faster, and we were stable again around noon, but upon turning everything back on we found we completely lost thinman, the main web server. Totally dead. However, quite luckily, we happened to have a spare old frankenstein machine kicking around, and I was able to do a brain transplant i.e. swap the drives from thinman to this other machine. Now this other machine thinks it is thinman and is working quite well as a web server. Dodged a major bullet there ...
Tales from Alternate Earths III is out now, containing such short stories as Gunpowder Treason (what if Guy Fawkes succeeded?), Not my Monkey (what if the Empire-of-Japan scientists knew as much about brain transplants as the Nazi scientists knew about rockets?), my own Levskis Boots (what if Vasil Levski had boots?) and many others.. If you want to know more, heres the conversation a few of us had about the anthology and alternate history in general.. Interchange also…continues to be available for purchase.. And thats probably it for publications for a few months. Im trying to spread the word, so if know of a podcast I should be on or some other form of advertising I should be doing, tell me. A review or two wouldnt hurt either. Publishers will look to the success of Junction and Interchange when they consider whether or not to buy my next book..

The structure of a biological scaffold is a major determinant of its biological characteristics and its interaction with cells. An acellular dermis tissue transplant must undergo a series of processing steps, to remove cells and genetic material and provide the sterility required for surgical use. During manufacturing and sterilization the structure and composition of tissue transplants may change. The composition of the human cell-free dermis transplant Epiflex® was investigated with specific attention paid to its structure, matrix composition, cellular content and biomechanics. We demonstrated that after processing, the structure of Epiflex remains almost unchanged with an intact collagen network and extracellular matrix (ECM) protein composition providing natural cell interactions. Although the ready to use transplant does contain some cellular and DNA debris, the processing procedure results in a total destruction of cells and active DNA which is a requirement for an immunologically inert and

Scientists under the leadership of the University of Bonn have harnessed rabies viruses for assessing the connectivity of nerve cell transplants: coupled with a green fluorescent protein, the viruses show where replacement cells engrafted into mouse brains have connected to the host neural network. A clearing procedure which turns the brain into a glass-like state and light sheet fluorescence microscopy are used to visualize host-graft connections in a whole-brain preparation. The approach opens exciting prospects for predicting and optimizing the ability of neural transplants to functionally integrate into a host nervous system. The results have now been published in the specialist journal Nature Communications.. Many diseases and injuries result in a loss of nerve cells. Scientists are working on tackling this challenge by transplanting neurons. In Parkinsons disease, for instance, this is attempted with implanted dopamine-producing nerve cells. The key question for such techniques is ...
How the immense population of neurons that constitute the human cerebral neocortex is generated from progenitors lining the cerebral ventricle and then distributed to appropriate layers of distinctive cytoarchitectonic areas can be explained by the radial unit hypothesis. According to this hypothesis, the ependymal layer of the embryonic cerebral ventricle consists of proliferative units that provide a proto-map of prospective cytoarchitectonic areas. The output of the proliferative units is translated via glial guides to the expanding cortex in the form of ontogenetic columns, whose final number for each area can be modified through interaction with afferent input. Data obtained through various advanced neurobiological techniques, including electron microscopy, immunocytochemistry, [3H]thymidine and receptor autoradiography, retrovirus gene transfer, neural transplants, and surgical or genetic manipulation of cortical development, furnish new details about the kinetics of cell proliferation, ...
The American Association of Kidney Patients is a voluntary patient organization, which has been dedicated to improving the lives of fellow kidney patients and their families by helping them deal with the physical, emotional and social impact of kidney disease for more than 40 years. The programs offered by AAKP inform and inspire patients and their families to better understand their condition, adjust more readily to their circumstances and assume more normal, productive lives. To accomplish these goals, AAKP engages in a variety of educational and supportive programs designed: 1) to assist patients both to learn more about their disease and to become active participants in planning and managing their treatment; 2) to improve patient understanding of and access to rehabilitation; 3) to work together for the improvement of public programs that help kidney patients meet their financial and personal needs; 4) to reflect the views and concerns of patients to public policy makers and others in the ...
The results of this study illustrate the remarkable regenerative capacity of the skeletal muscle of young mice to ischemic injury. The muscles most affected by FAL were the soleus and gastrocnemius of the lower leg. There was also evidence of ischemic injury in the thigh, but to a lesser extent. During the first 3 days following surgery, there was microscopic evidence of muscle damage and a pronounced loss of function. By day 7, the histological evidence showed a substantial resolution of the injury, and contractile force had been essentially normalized. By 28 days the muscles microscopic appearance was largely restored to baseline. Consistent with these findings is the fact that of the 1,289 known transcripts we identified as differentially expressed between ligated and sham surgery controls, none were induced or repressed by the day 28 time point.. Because the gene expression results are too extensive to be discussed in a single paper, we present selective results from the data set that we ...
For the first time, scientists have transplanted neural cells derived from a monkeys skin into its brain and watched the cells develop into several types of mature brain cells, according to the authors of a new study in Cell Reports. After six months, the cells looked entirely normal, and were only detectable because they initially were tagged with a fluorescent protein.. Because the cells were derived from adult cells in each monkeys skin, the experiment is a proof-of-principle for the concept of personalized medicine, where treatments are designed for each individual.. And since the skin cells were not foreign tissue, there were no signs of immune rejection - potentially a major problem with cell transplants. When you look at the brain, you cannot tell that it is a graft, says senior author Su-Chun Zhang, a professor of neuroscience at the University of Wisconsin-Madison. Structurally the host brain looks like a normal brain; the graft can only be seen under the fluorescent ...

Authors: Smith, Gaynor A. , Heuer, Andreas , Klein, Alexander , Vinh, Ngoc-Nga , Dunnett, Stephen B. , Lane, Emma L. Article Type: Short Communication Abstract: The transplantation of dopamine-rich tissue into the putamen of patients with Parkinsons disease shows much potential for use as a therapeutic strategy. However, a number of grafted individuals subsequently developed a set of abnormal involuntary movements (AIMs), unrelated to the dyskinesia caused by L-DOPA treatment, which have been termed graft-induced dyskinesia. Given the small number of patients, pre-clinical modeling of graft-induced dyskinesia in animal models will be critical to determine the underlying mechanisms and amelioration potential of this technique. Here we show that abnormal involuntary movements of the limbs, trunk and face can be observed in transplanted hemi-parkinsonian mice following …amphetamine administration, similar to those previously described to model graft-induced dyskinesias in rats. C57Bl6 and CD1 ...
r norman scripsit: , Some poor reader had a legitimate, albeit rather naive, question about , brain transplants, and you ridicule him unmercifully. Why dont you , try educating, instead. I dont care about that. Winding up people on usenet is one of my favourite hobbies, although this was one of my few serious posts. Well, serious-ish. I admit I deliberately phrased it in a very provocative way, and I knew there was no way to answer it. For a long time I have been interested in locked in syndrome, and the situation outlined in Whites articles is in a sense the ultimate locked in state: no imputs, no outputs, no way to communicate with the isolated brain. Of course the transplant is not really necessary, severing the cranial nerves would obtain the same results. Incidentally, that would be an interesting punishment for some heinous criminals: induce the ultimate locked in state, then pump their bodies full of chemicals known to produce a state of anguish and fear.

Recently in the news, there was an interesting story about a 38 year old woman who had been forced into early menopause because of two rounds of cancer treatments. Fortunately, she and her doctors had decided that it would be beneficial for her to freeze one of her ovaries before starting her second treatment program.
A complementary approach to cell transplantation (which involves replacing cells once already lost) is to protect damaged or traumatised neurones of the host brain from the assault of injury or disease. A wide number of compounds have been identified which have the potential to block processes of cell death and to promote regrowth of damaged cells, including growth factors, antiapoptotic agents, antioxidants and transcription factors. However a common problem for their use is that they dont get into the brain when injected or ingested peripherally. We are developing ways to deliver neuroprotective agents into precise sites in the brain both by engineering cells for transplantation (ex vivo gene therapy) and by using viral vectors for direct intracerebral delivery (in vivo gene therapy). ...
HERMES fosters the mission of healing disabling brain disorders by means of brain tissue transplants, a reality that is only possible to date for other organs of the human body
Factors which influence development of the nervous system and its regenerative capacities can be studied with the technique of neural transplantation. The first three experiments examined the mechanisms of pathway guidance which operate in development by transplanting target structures in the visual system of the newborn Long-Evans rat. The final experiment addresses the issue of the repair of spinal cord injury in adult Long-Evans rats by utilizing neural transplantation of embryonic spinal cord segments. In all cases, embryonic day 13-15 neural structures were dissected from fetuses and transplanted to recipients. After one to two months the animal was anesthetized, the transplant visualized and injected with horseradish peroxidase (HRP). Twenty-four hours later the animals were reanesthetized and perfused transcardially with buffered solutions of 0.5% glutaraldehyde followed by 0.2% glutaraldehyde. Then the brains were removed, cut on a freezing microtome, and processed with either of two ...

The neocortex is patterned in layers of neurons that are generated in an orderly sequence during development. This correlation between cell birthday and laminar fate prompted an examination of how neuronal phenotypes are determined in the developing cortex. At various times after labeling with [3H]thymidine, embryonic progenitor cells were transplanted into older host brains. The laminar fate of transplanted neurons correlates with the position of their progenitors in the cell cycle at the time of transplantation. Daughters of cells transplanted in S-phase migrate to layer 2/3, as do host neurons. Progenitors transplanted later in the cell cycle, however, produce daughters that are committed to their normal, deep-layer fates. Thus, environmental factors are important determinants of laminar fate, but embryonic progenitors undergo cyclical changes in their ability to respond to such cues. ...
OXB-202Gene-based treatment for corneal graft rejectionStatus: Phase I/II study in preparationCorneal graft rejectionCornea grafts are one of the most successful tissue transplants, but over time a significant number are rejected due to corneal neovascularisation. Currently, approximately 100,000 transplants are performed each year, but with this representing only 1% of those requiring treatment the number is predicted to increase substantially. Our approach
Injuries to the brain and spinal cord have major clinical consequences with high costs for healthcare systems. Neural cell transplantation therapies have significant translational potential to promote regeneration post-injury with clinical trials commencing for various pathologies. However, there are challenges associated with current clinical approaches used for systemic or direct delivery of transplant cells to neural tissue in regenerative applications. These include risks associated with surgical microinjection into neural tissue (e.g. haemorrhage, cell clumping) and high cell loss due to systemic clearance or with cell passage through fine gauge needles into densely packed neural tissue. This article presents lines of evidence supporting the concept that cell spray delivery technology can offer significant translational benefits for neural transplantation therapy, versus current cell delivery methods. Potential benefits include rapid/homogenous cell delivery, release over large surface ...

Numerous studies have demonstrated the use of ESC-derived DA neurons for grafting in animal models of PD (17); however, it has remained unclear which stage of differentiation and what particular population of cells is most effective at inducing functional benefits upon transplantation in vivo. Fetal tissue studies have focused on the grafting of ventral mesencephalic tissue isolated at a stage in which the majority of developing DA neurons are postmitotic, which is E12-E13 in mice (18) and E14-E15 (19) in rats. In human fetal grafting studies, increased survival of TH+ neurons has been reported for tissue derived from embryos at 5 to 8 weeks after conception when using suspension grafts and up to 9 weeks after conception for solid grafts (20). In all of those cases, however, the grafted population was composed of a heterogeneous pool of cells at various stages of differentiation and typically contained less than 20% DA neurons (21). One recent study used purified DA neurons derived from a ...
The capacity of the mammalian brain to support the physiological function of allografts was assessed in parathyroidectomized Fischer strain rats bearing either isografts or immunogenic DA allografts of parathyroid glands implanted in their cerebral cortices. Established isografts and allografts survived indefinitely in the brain, maintaining normal serum calcium levels, with equal numbers of spontaneous failures (18-21%) in each group. Similarly, both MHC-compatible and incompatible skin allografts survived and were functional at 40-50 days postgrafting as assessed by: continued formation of keratin; the presence of differentiated hair follicles and sebaceous glands; and frequent mitotic figures. No serum alloantibodies were induced by either MHC-incompatible parathyroid glands or skin in this site. However, both types of allografts were promptly rejected or failed to become established in the brains of specifically presensitized hosts. Furthermore, when Fischer hosts with long-established ...

Cultured limbal tissue transplants have become widely used over the last decade as a treatment for limbal stem cell deficiency (LSCD). While the number of patients afflicted with LSCD in Australia and New Zealand is considered to be relatively low, the impact of this disease on quality of life is so severe that the potential efficacy of cultured transplants has necessitated investigation. We presently review the basic biology and experimental strategies associated with the use of cultured limbal tissue transplants in Australia and New Zealand. In doing so, we aim to encourage informed discussion on the issues required to advance the use of cultured limbal transplants in Australia and New Zealand. Moreover, we propose that a collaborative network could be established to maintain access to the technology in conjunction with a number of other existing and emerging treatments for eye diseases. ...

Fetal locus coeruleus neurons were implanted as a cell suspension into hippocampi deprived of their innate noradrenalin (NA) innervation by intraventricular 6-hydroxydopamine treatment. Dialysis probes of the loop type were implanted into the dorsal hippocampus 1 - 2 days before each experiment, i.e. 7 - 11 months after grafting. Age-matched intact and lesion-only animals served as controls. Microscopic analysis showed a graft-derived tyrosine hydroxylase immunoreactive, presumably noradrenergic, fibre network throughout the dorsal hippocampal formation, surrounding the probe site. The innervation density varied from sub- to supranormal. The grafts restored baseline NA release in the graft-reinnervated hippocampus to near-normal levels both in awake and halothane-anaesthetized animals. ...

Bornavirus (BDV) owes its name to the town of Borna, Germany, where a virus epidemic in 1885 wiped out a regiment of cavalry horses. BDV infects a range of birds and mammals, including humans. It is unique because it infects only neurons, establishing a persistent infection in its hosts brain, and its entire life cycle takes place in the nucleus of the infected cells. Feschotte said this intimate association of BDV with the cell nucleus prompted researchers to investigate whether bornaviruses may have left behind a record of past infection in the form of endogenous elements. They searched the 234 known eukaryotic genomes (those genomes that have been fully sequenced) for sequences that are similar to that of BDV. The researchers unearthed a plethora of endogenous Borna-like N (EBLN) elements in many diverse mammals, Feschotte said ...

In the past 50 years, isolated blood platelets have had restricted use in wound healing, cancer therapy, and organ and tissue transplant, to name a few. The major obstacle for its unrestricted use has been, among others, the presence of ultrahigh concentrations of growth factors and the presence of both pro-angiogenic and anti-angiogenic proteins. To overcome this problem requires the isolation and separation of the membrane bound secretory vesicles containing the different factors. In the current study, high-resolution imaging of isolated secretory vesicles from human platelets using atomic force microscopy (AFM) and mass spectrometry enabled characterization of the remaining vesicles size and composition following their immunoseparation ...

So: the schistosomes life cycle. They start out as little eggs which leave the adults host (humans) through the waste systems in urine or feces. These eggs then hatch into the first larval stage, which is called a miracidium. The miracidium seeks out a snail and burrows through its tissues to get to its gonads. There, it asexually reproduces to create sporocysts, and in the process thousands of copies of itself while castrating the unlucky mollusk. When the time is right, these copies transform again into cercaria, which kind of look like sperm, and for the same function: swimming. Upon bursting out of the snail, these little swimmers hunt down the nearest suitable host they can find by actually swimming towards them ...
