Artificial Organs
Devices intended to replace non-functioning organs. They may be temporary or permanent. Since they are intended always to function as the natural organs they are replacing, they should be differentiated from PROSTHESES AND IMPLANTS and specific types of prostheses which, though also replacements for body parts, are frequently cosmetic (EYE, ARTIFICIAL) as well as functional (ARTIFICIAL LIMBS).

Liver Failure, Acute
A form of rapid-onset LIVER FAILURE, also known as fulminant hepatic failure, caused by severe liver injury or massive loss of HEPATOCYTES. It is characterized by sudden development of liver dysfunction and JAUNDICE. Acute liver failure may progress to exhibit cerebral dysfunction even HEPATIC COMA depending on the etiology that includes hepatic ISCHEMIA, drug toxicity, malignant infiltration, and viral hepatitis such as post-transfusion HEPATITIS B and HEPATITIS C.
Bioreactors
Tools or devices for generating products using the synthetic or chemical conversion capacity of a biological system. They can be classical fermentors, cell culture perfusion systems, or enzyme bioreactors. For production of proteins or enzymes, recombinant microorganisms such as bacteria, mammalian cells, or insect or plant cells are usually chosen.
Liver Failure
Severe inability of the LIVER to perform its normal metabolic functions, as evidenced by severe JAUNDICE and abnormal serum levels of AMMONIA; BILIRUBIN; ALKALINE PHOSPHATASE; ASPARTATE AMINOTRANSFERASE; LACTATE DEHYDROGENASES; and albumin/globulin ratio.

Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
Excitability and contractility of skeletal muscle engineered from primary cultures and cell lines. (1/58)
The purpose of this study was to compare the excitability and contractility of three-dimensional skeletal muscle constructs, termed myooids, engineered from C2C12 myoblast and 10T1/2 fibroblast cell lines, primary muscle cultures from adult C3H mice, and neonatal and adult Sprague-Dawley rats. Myooids were 12 mm long, with diameters of 0.1-1 mm, were excitable by transverse electrical stimulation, and contracted to produce force. After approximately 30 days in culture, myooid cross-sectional area, rheobase, chronaxie, resting baseline force, twitch force, time to peak tension, one-half relaxation time, and peak isometric force were measured. Specific force was calculated by dividing peak isometric force by cross-sectional area. The specific force generated by the myooids was 2-8% of that generated by skeletal muscles of control adult rodents. Myooids engineered from C2C12-10T1/2 cells exhibited greater rheobase, time to peak tension, and one-half relaxation time than myooids engineered from adult rodent cultures, and myooids from C2C12-10T1/2 and neonatal rat cells had greater resting baseline forces than myooids from adult rodent cultures.

Recently, tissue engineering approaches using injectable, in situ gel forming systems have been reported. In this review, the gelation processes and several injectable systems that exhibit in situ gel formation at physiological conditions are discussed. Applications of selected injectable systems (alginate, chitosan, hyaluronan, polyethylene oxide/polypropylene oxide) in tissue engineering are also described. Injectable polymer formulation can gel in vivo in response to temperature change (thermal gelation), pH change, ionic cross-linking, or solvent exchange. Kinetics of gelation is directly affected by its mechanism. Injectable formulations offer specific advantages over preformed scaffolds such as: possibility of a minimally invasive implantation, an ability to fill a desired shape, and easy incorporation of various therapeutic agents. Several factors need to be considered before an injectable gel can be selected as a candidate for tissue engineering applications. Apart from tissue-specific cell-matrix interactions, the following gel properties need to be considered: gelation kinetics, matrix resorption rate, possible toxicity of degradation products and their elimination routes, and finally possible interference of the gel matrix with histogenesis. (+info)Tissue engineering strategies for adipose tissue repair. (3/58)
Tissue engineering is a relatively young field that combines engineering, clinical science, and life sciences to, in part, repair or regrow tissues. Adipose tissue has recently become a focus area for tissue engineering, encouraged by the large number of reconstructive, cosmetic, and correctional indications that could be addressed with clinically translatable adipose tissue engineering strategies. This review discusses the three aspects of an adipose construct, namely cell types, scaffold, and microenvironment, and presents current tissue engineering strategies under pursuit. (+info)Tissue engineering in the cardiovascular system: progress toward a tissue engineered heart. (4/58)
Achieving the lofty goal of developing a tissue engineered heart will likely rely on progress in engineering the various components: blood vessels, heart valves, and cardiac muscle. Advances in tissue engineered vascular grafts have shown the most progress to date. Research in tissue-engineered vascular grafts has focused on improving scaffold design, including mechanical properties and bioactivity; genetically engineering cells to improve graft performance; and optimizing tissue formation through in vitro mechanical conditioning. Some of these same approaches have been used in developing tissue engineering heart valves and cardiac muscle as well. Continued advances in scaffold technology and a greater understanding of vascular cell biology along with collaboration among engineers, scientists, and physicians will lead to further progress in the field of cardiovascular tissue engineering and ultimately the development of a tissue-engineered heart.

Tissue engineering (TE) is a new interdisciplinary field of applied research combining engineering and biosciences together with clinical application, mainly in surgical specialities, to develop living substitutes for tissues and organs. Tissue engineering approaches can be categorized into substitutive approaches, where the aim is the ex vivo construction of a living tissue or organ similar to a transplant, vs. histioconductive or histioinductive concepts in vivo. The main successful approaches in developing tissue substitutes to date have been progresses in the understanding of cell-cell interactions, the selection of appropriate matrices (cell-matrix interaction) and chemical signalling (cytokines, growth factors) for stimulation of cell proliferation and migration within a tissue-engineered construct. So far virtually all mammalian cells can be cultured under specific culture conditions and in tissue specific matrices. Future progress in cell biology may permit the use of pluripotent stem cells for TE. The blueprint for tissue differentiation is the genome: for this it is reasonable to combine tissue engineering with gene therapy. The key to the progress of tissue engineering is an understanding between basic scientists, biochemical engineers, clinicians, and industry. (+info)Engineering of vascular ingrowth matrices: are protein domains an alternative to peptides? (6/58)
Anastomotic intimal hyperplasia and surface thrombogenicity are the main reasons for the high failure rate of prosthetic small-diameter vascular grafts. While anastomotic intimal hyperplasia is a multifactorial event, ongoing surface thrombogenicity is primarily caused by the lack of an endothelium, even after years of clinical implantation. After decades of poorly performing synthetic artery-grafts, tissue engineering has emerged as a promising approach to generate biologically functional bio-synthetic hybrid grafts mimicking native arteries regarding the presence of an endothelial lining on the blood surface. "In vitro endothelialization" represented the first generation of such tissue-engineered vascular grafts, utilising cell culture techniques for the creation of a confluent autologous endothelium on ePTFE grafts. The clinical long-term results with this method in almost 200 patients are highly encouraging, showing patencies equal to vein grafts. Since "in vitro endothelialization" requires cell culture facilities, it will always be confined to large centres. Therefore, research of the 1990s turned to the development of spontaneously endothelializing implants, to make tissue-engineered grafts amenable to the entire vascular-surgical community. Apart from scaffold designs allowing transmural ingrowth, biological signalling through a facilitating ingrowth matrix holds a key to spontaneous endothelialization. In biological signalling, the increasingly deeper understanding of bio-active molecules and the discovery of domains and peptide sequences during the 1980s created the expectation in the 1990s that peptide signalling may be all that is needed. This present review highlights the possible problems associated with such a reductionist approach. Using the fibronectin molecule, we demonstrated that domains may be more suitable modules in tissue engineering than peptide sequences. (+info)Peripheral nerve injury: a review and approach to tissue engineered constructs. (7/58)
Eleven thousand Americans each year are affected by paralysis, a devastating injury that possesses associated annual costs of $7 billion (American Paralysis Association, 1997). Currently, there is no effective treatment for damage to the central nervous system (CNS), and acute spinal cord injury has been extraordinarily resistant to treatment. Compared to spinal cord injury, damage to peripheral nerves is considerably more common. In 1995, there were in excess of 50,000 peripheral nerve repair procedures performed. (National Center for Health Statistics based on Classification of Diseases, 9th Revision, Clinical Modification for the following categories: ICD-9 CM Code: 04.3, 04.5, 04.6, 04.7). These data, however, probably underestimate the number of nerve injuries appreciated, as not all surgical or traumatic lesions can be repaired. Further, intraabodominal procedures may add to the number of neurologic injuries by damage to the autonomic system through tumor resection. For example, studies assessing the outcome of impotency following radical prostatectomy demonstrated 212 of 503 previously potent men (42%) suffered impotency when partial or complete resection of one or both cavernosal nerve(s). This impotency rate decreased to 24% when the nerves were left intact (Quinlan et al., J. Urol. 1991;145:380-383; J. Urol. 1991;145:998-1002). (+info)Self-assembly and mineralization of peptide-amphiphile nanofibers. (8/58)
We have used the pH-induced self-assembly of a peptide-amphiphile to make a nanostructured fibrous scaffold reminiscent of extracellular matrix. The design of this peptide-amphiphile allows the nanofibers to be reversibly cross-linked to enhance or decrease their structural integrity. After cross-linking, the fibers are able to direct mineralization of hydroxyapatite to form a composite material in which the crystallographic c axes of hydroxyapatite are aligned with the long axes of the fibers. This alignment is the same as that observed between collagen fibrils and hydroxyapatite crystals in bone. (+info) Acute liver failure refers to a severe and rapid loss of liver function that can occur within days or weeks, leading to life-threatening complications. This condition is different from chronic liver disease, which develops over months or years and often has a more gradual onset.
Causes:
1. Viral hepatitis (hepatitis A, B, or C)
2. Overdose of medications or supplements
3. Toxic substances (e.g., alcohol, drugs, or chemicals)
4. Sepsis or other infections that spread to the liver
5. Certain autoimmune disorders (e.g., hemochromatosis, Wilson's disease)
6. Cancer that has metastasized to the liver
7. Blood vessel blockage or clotting in the liver
8. Lack of blood flow to the liver
Symptoms:
1. Jaundice (yellowing of skin and eyes)
2. Nausea and vomiting
3. Abdominal swelling and discomfort
4. Fatigue, weakness, and loss of appetite
5. Confusion or altered mental state
6. Seizures or coma
7. Pale or clay-colored stools
8. Dark urine
Diagnosis:
1. Physical examination and medical history
2. Laboratory tests (e.g., liver function tests, blood tests, imaging studies)
3. Biopsy of the liver tissue (to rule out other liver diseases)
Treatment:
1. Supportive care (fluids, nutrition, and medication to manage symptoms)
2. Addressing underlying causes (e.g., stopping alcohol or drug use, treating infections)
3. Transjugular intrahepatic portosystemic shunt (TIPS), a procedure that creates a new pathway for blood to flow through the liver
4. Liver transplantation (in severe cases where other treatments have failed)
Prognosis:
The prognosis for acute liver failure depends on the underlying cause of the condition and the severity of the liver damage. In general, the earlier the diagnosis and treatment, the better the outcome. However, acute liver failure can be a life-threatening condition, and the mortality rate is high, especially in cases where there is severe liver damage or no available donor liver for transplantation.
Liver failure, also known as hepatic failure or liver insufficiency, is a condition where the liver is no longer able to perform its normal functions, leading to various symptoms and complications. The liver plays a crucial role in detoxifying the body, producing bile to aid in digestion, regulating blood sugar levels, and producing important proteins and nutrients. When the liver fails, these functions are disrupted, leading to a range of health problems.
There are several causes of liver failure, including:
1. Alcohol-related liver disease: Prolonged and excessive alcohol consumption can damage liver cells, leading to inflammation, scarring, and eventually liver failure.
2. Viral hepatitis: Hepatitis A, B, and C are viral infections that can cause inflammation and damage to the liver, leading to liver failure.
3. Non-alcoholic fatty liver disease (NAFLD): A condition where there is an accumulation of fat in the liver, leading to inflammation and scarring.
4. Drug-induced liver injury: Certain medications can cause liver damage and failure, especially when taken in high doses or for extended periods.
5. Genetic disorders: Certain inherited conditions, such as hemochromatosis and Wilson's disease, can cause liver damage and failure.
6. Acute liver failure: This is a sudden and severe loss of liver function, often caused by medication overdose or other toxins.
7. Chronic liver failure: A gradual decline in liver function over time, often caused by cirrhosis or NAFLD.
Symptoms of liver failure can include:
1. Jaundice (yellowing of the skin and eyes)
2. Fatigue
3. Loss of appetite
4. Nausea and vomiting
5. Abdominal pain
6. Confusion and altered mental state
7. Easy bruising and bleeding
Diagnosis of liver failure is typically made through a combination of physical examination, medical history, and laboratory tests, such as blood tests to check for liver enzymes and bilirubin levels. Imaging tests, such as ultrasound and CT scans, may also be used to evaluate the liver.
Treatment of liver failure depends on the underlying cause and severity of the condition. In some cases, a liver transplant may be necessary. Other treatments may include medications to manage symptoms, such as nausea and pain, and supportive care to maintain nutrition and hydration. In severe cases, hospitalization may be required to monitor and treat complications.
Prevention of liver failure is important, and this can be achieved by:
1. Avoiding alcohol or drinking in moderation
2. Maintaining a healthy weight and diet
3. Managing underlying medical conditions, such as diabetes and high blood pressure
4. Avoiding exposure to toxins, such as certain medications and environmental chemicals
5. Getting vaccinated against hepatitis A and B
6. Practicing safe sex to prevent the spread of hepatitis B and C.
