Whether you are a computer technician, a gamer, or simply someone who uses a computer for everyday tasks, this article will help you better understand the world of computer hardware. Introduction to Computer Hardware Computer hardware refers to the physical components that make up a computer system. It includes everything from the processor and memory to input/output devices such as the keyboard and monitor. In this article, we will explore the different types of computer hardware and their functions. What is Computer Hardware Computer hardware refers to the physical components of a computer system. It includes all the components that can be touched, seen, and used to interact with a computer, such as the monitor, keyboard, and mouse. Hardware is different from computer software, which refers to the programs and applications that run on a computer system. History of Computer Hardware The history of computer hardware dates back to the 1820s when Charles Babbage, an English mathematician, and inventor, designed the first analytical engine, which was considered to be the first mechanical computer. With time, more complex electronic computers were developed, including the first Intel microprocessor in 1971. Since then, computer hardware has continued to evolve, becoming

Oxidative Stress and Its Relationship With Adenosine Deaminase Activity in Various Stag... - 0 views

  • Reduced SOD activity might be responsible for excessive accumulation of superoxide anions leading to increased free radical mediated injury. Increased free radical production has been shown to be responsible for chromosomal damage leading to mutagenecity, cell proliferation and carcinogenesis. SOD activity showed marked improvement after mastectomy indicating the lowering of oxidative stress.
  • The increased production of reactive oxygen species causes oxidative stress leading to cell proliferation and hence increased inflammatory conditions
  • Superoxide dismutase is an important antioxidant enzyme which decomposes the harmful superoxide anions into hydrogen peroxide thus protects the body from the action of free radicals

  • Females suffering from breast cancer had significantly decreased Superoxide dismutase (SOD) and reduced glutathione (GSH) levels in comparison to normal females
  • ADA seems to be a promising marker of inflammation in breast cancer thereby suggesting that it can be used as a diagnostic tool to detect the stage of breast cancer along with cytopathological studies
  • In conclusion, our study confirmed the role of oxidative stress in the pathogenesis of breast cancer.
  • Another potent antioxidant molecule is reduced glutathione. It acts as reductant which converts hydrogen peroxide into water and reduces lipid peroxidation products into their corresponding alcohols and thus mediates protective action.
  • In the present study, significantly low SOD activity has been observed in female patients suffering from carcinoma breast both pre as well as post operative in comparison to healthy females.
  • The compromised antioxidant defence system produces the oxidative stress which in turn creates the inflammatory response shown by concomitant increased adenosine deaminase (ADA) activity in female patients.
  • Increased ADA activity in breast cancer patients has also been reported
  • We observed significantly decreased SOD activity and GSH levels in patients belonging to clinical stage 4 as compared to those having stages 1, 2 or 3 of breast cancer.
  • increased oxidative stress gives rise to inflammation which could further aggravates the disease
  • Antioxidant status was highly depressed in advanced stages of breast cancer as compared to initial stage.
  • In the present study, significantly low GSH levels were observed in female patients of carcinoma breast as compared to normal females
  • Walia et al. (1995) reported increased ADA activity in breast cancer patients as compared to age matched normal subjects.
  • These free radicals are able to cause damage to membrane, mitochondria and macromolecules including proteins, lipids and DNA and actively take part in cell proliferation. This cascade in turn generates the inflammatory response and causes the progression of the disease.
  • Experimental and epidemiological evidences implicate the involvement of oxygen derived free radical in the pathogenesis of breast cancer.
  • Breast carcinoma involves a cascade of events that are highly inflammatory.
  • Marked oxidative stress in stage 4 of breast cancer indicated advancement of the disease, hence checking oxidative stress at initial stage could be helpful for controlling the progression of the disease.
  • They concluded that ADA is a better probable parameter for detection of breast cancer
  • Adenosine deaminase enzyme (ADA) catalyzes the conversion of adenosine to inosine which finally gets converted to uric acid
  • serum ADA activity tends to increase with advancing age,
  • Prevalence of oxidative stress gives rise to inflammation.
  •  
    Study finds a reduction in SuperOxide Dismutase and Glutathione Perioxidase in advancing breast cancer.  Cancer is a high oxidative stress disease that results in inflammation, mitochondrial dysfunction and proliferation.  Adenosine Deaminase (ADA) is proposed to be another biomarker to assess tumor stage.

  •  
    This study finds that AGE, advanced glycation end products, play a significant role in free radical generation and neurodegenerative disease. Quote: "... pharmacologoical approaches which break the vicious cycle of oxidative stress and neurodegeneration offer new opportunities for the treatment of AD. These approaches include AGE- inhibitors, antioxidants, and anti-inflammatory substances which prevent radical production." They focus on the pharmacological, how about the natural first?

Branched-chain amino acids in liver diseases - 0 views

  • Serum concentrations of BCAAs are decreased, while the concentrations of the aromatic amino acids (AAAs) phenylalanine and tyrosine are increased, in patients with advanced liver diseases, resulting in a low ratio of BCAAs to AAAs, a ratio called the Fischer ratio
  • BCAAs were reported to stimulate the production of hepatocyte growth factor
  • a simplified Fischer ratio, the BCAA to tyrosine ratio (BTR), has been reported useful for predicting serum albumin concentration one year later
  • ...10 more annotations...
  • BCAA supplementation was shown to delay the progression of CCl4-induced chronic liver injury in a rat model by reducing hepatic apoptosis
  • BCAAs promoted hepatocyte regeneration in a rat model of hepatectomy
  • BCAA supplementation for advanced cirrhotic patients improves nutritional status and quality of life
  • BCAAs activate mTOR and subsequently increase the production of eukaryotic initiation factor 4E-binding protein-1 and ribosomal protein S6 kinase, which upregulate the synthesis of albumin
  • BCAAs were shown to improve homeostasis model assessment scores for insulin resistance (HOMA-IR) and beta cell function (HOMA-%B) in patients with chronic liver disease, indicating that BCAAs can ameliorate insulin resistance
  • Several clinical trials have suggested that BCAA supplementation improves the prognosis of cirrhotic patients
  • A low Fischer ratio has been associated with hepatic encephalopathy
  • Treatment with BCAAs may therefore have a beneficial effect on patients with hepatic encephalopathy mainly by compensating decreased ratio of BCAAs to AAAs, but not by reducing serum ammonia levels
  • Two randomized studies also showed that BCAAs did not clearly prevent HE in patients with advanced cirrhosis, although BCAAs prevented the progression of hepatic failure
  • a systematic review with meta-analyses on the effect of oral BCAAs for the treatment of HE was published[66]. The review has revealed that supplementation of oral BCAAs in cirrhotic patients inhibits the manifestation of HE, especially in patients with overt HE rather than those with minimal HE, but showed no effect on the survival of those patients[66]. Thus, oral administration of BCAAs is the treatment of choice in cirrhotic patients with HE
