Computer Science: Computer hardware - 0 views

  •  
    Computer Science Tuesday, April 25, 2023 Computer hardware Computer hardware is the physical components that make up a computer system. It includes everything from the central processing unit (CPU) to the monitor, keyboard, and mouse. Understanding the different types of hardware and how they work together is essential for anyone who works with computers. In this article, we will explore the various components of computer hardware, including internal and external components, and the peripherals that connect to them. We will also discuss the importance of hardware maintenance, the latest advancements in computer technology, and factors to consider when choosing the right hardware for your needs. 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

Plasma lipoproteins: composition, structure and biochemistry - 0 views

  • triacylglycerols
  • The most abundant lipid constituents are triacylglycerols, free cholesterol, cholesterol esters and phospholipids (phosphatidylcholine and sphingomyelin especially ), though fat-soluble vitamins and anti-oxidants are also transported in this way
  • the lipoprotein aggregates should be described in terms of the different protein components or apoproteins (or 'apolipoproteins'
  • ...8 more annotations...
  • these classes can be further refined by improved separation procedures, and intermediate-density lipoproteins (IDL) and subdivisions of the HDL (e.g. HDL1, HDL2, HDL3 and so forth
  • Density is determined largely by the relative concentrations of triacylglycerols and proteins and by the diameters of the broadly spherical particles
  • Lipoproteins are spherical (VLDL, LDL, HDL) to discoidal (nascent HDL) in shape with a core of non-polar lipids, triacylglycerols and cholesterol esters, and a surface monolayer, ~20Å thick, consisting of apoproteins, phospholipids and non-esterified cholesterol, which serves to present a hydrophobic face to the aqueous phase
  • the various lipid components should not be considered as absolute, as they are in a state of constant flux
  • Apo A1 is the main protein component of HDL
  • Apo A2 is the second most important HDL apolipoprotein
  • the main groups are classified as chylomicrons (CM), very-low-density lipoproteins (VLDL), low-density lipoproteins (LDL) and high-density lipoproteins (HDL), based on the relative densities of the aggregates on ultracentrifugation
  • The lipoproteins can be categorised simplistically according to their two main metabolic functions. The principal role of the chylomicrons and VLDL is to transport triacylglycerols ‘forward’ as a source of fatty acids from the intestines or liver to the peripheral tissues. In contrast, the HDL remove excess cholesterol from peripheral tissues and deliver it to the liver for excretion in bile in the form of bile acids (‘reverse cholesterol transport’). While these functions are considered separately here for convenience, it should be recognised that the processes are highly complex and inter-related, and they involve transfer of apoproteins, enzymes and lipid constituents among the heterogeneous mix of all the lipoprotein fractions.

Endocrinology of the Aging Male - 0 views

  • All steps beyond the formation of pregnenolone take place in the smooth endoplasmic reticulum
  • Cytochrome P450 enzyme, CYP11A is located on the inner mitochondrial membrane and catalyses the rate limiting step of pregnenolone synthesis
  • Estrogen and related steroids, thyroid hormone and insulin increase SHBG levels.

  • SHBG decreases in response to androgens, and in the presence of hypothyroidism, and insulin resistance.
  • Plasma SHBG levels tend to increase with increasing age
  • The apparent metabolic clearance rate of testosterone is decreased in elderly as compared to younger men
  • Testosterone circulates predominantly bound to the plasma proteins SHBG and albumin, with high and low affinity respectively
  • Testosterone is secreted in a pulsatile fashion
  • Current clinical guidelines suggest at least two measurements
  • In adult men, there is a well-documented diurnal variation (particularly in younger subjects) in testosterone levels, which are highest in the early morning and progressively decline throughout the day to a nadir in the evening
  • In older men, the diurnal variation is blunted
  • it is standard practice for samples to be obtained between 0800 and 1100 h.
  • Testosterone and DHEA decline, whereas LH, FSH, and SHBG rise
  • DHT remains constant despite the decline of its precursor testosterone
  • Longitudinal studies show an average annual decline of 1–2% total testosterone levels, with decline in free testosterone more rapid because of increases in SHBG with aging
  • Massachusetts Male Aging Study (MMAS) data show DHEA, DHEAS, and Ae declining at 2–3% per year
  • DHT showed no cross-sectional age trend
  • Androstanediol glucuronide (AAG) declined cross-sectionally with age in the MMAS sample, at 0.6% per year
  • The EMAS data show that, consistent with the longitudinal findings of MMAS (Figure 1), the core hormonal pattern with increasing age is suggestive of incipient primary testicular dysfunction with maintained total testosterone and progressively blunted free testosterone associated with higher LH

      This author proves the point in the review of these two studies, that TT may remain constant in aging men, however, FT drops.
  • obesity impairs hypothalamic/pituitary function
  • Androgen deprivation in men with prostate cancer has been associated with increased insulin resistance, worse glycemic control, and a significant increase in risk of incident diabetes
  • Low serum testosterone is associated with the development of metabolic syndrome 116, 117 and type 2 diabetes. 118 SHBG has been inversely correlated with type 2 diabetes
  • Improvement in insulin sensitivity with testosterone treatment has been reported in healthy 121 and diabetic 122 adult men
  • In studies conducted in men with central adiposity, testosterone has been shown to inhibit lipoprotein lipase activity in abdominal adipose tissue leading to decreased triglyceride uptake in central fat depots. 123

Therapy in the Early Stage: Incretins - 0 views

  • Increased resistance to insulin action in the skeletal muscle and liver associated with enhanced hepatic glucose output and impaired insulin secretion due to a progressive decline of β-cell function are long-recognized core defects
  • in addition, other mechanisms/organs are involved, augmenting the pathological pathways: adipocytes (altered fat metabolism due to insulin resistance), gastrointestinal tract (incretin deficiency and/or resistance), pancreatic α-cells (hyperglucagonemia and increased hepatic sensitivity to glucagon), kidneys (enhanced glucose reabsorption), and central nervous system (insulin resistance)
  • β-cell failure

      and studies have shown that a reduction in insulin function will decrease LH production and thus lead to a decrease in Testosterone production in men.

  • Incretins are gut-derived hormones, members of the glucagon superfamily, released in response to nutrient ingestion (mainly glucose and fat)
  • They exert a wide range of effects, including stimulation of pancreatic insulin secretion in a glucose-dependent manner and play an important role in the local gastrointestinal and whole-body physiology
