24). CRRT uses diffusion (haemodialysis), convection (haemofiltration) or combines these two methods (heamodiafiltration) in order to achieve solute removal from the blood. Small molecular weight substances like potassium, urea and creatinine are efficiently removed through haemodialysis (Kellum, Mehta, Angus, Palevsky and Ronco, 2002, p.1858). For larger solute molecules, heamofiltration is the most efficient method of their removal in comparison with dialysis. In haemofiltration, filtration of plasma through the semi-permeable membrane is caused by hydrostatic pressure. In addition, solutes cross the membrane alongside the plasma which results in convective solute transport flowing in the same direction as water (Medve, Preda and Gondos, 2010, p. 104). Therefore, haemofiltration needs the use of replacement fluid to avert excessive removal of fluid, electrolyte depletion as well as iatrogenic acidosis. Since the plasma solute concentration is the same as that of the removed filtrate, concentration of the solutes in the blood plasma remaining need to be diluted using substitution fluid. ...Show more
Name: University: Course: Tutor: Date: Vascular Access in Continuous Renal Replacement Therapy Acute renal failure (ARF) also referred to as acute kidney injury alludes to sudden slowing of the kidney’s function resulting in elevation of plasma creatinine, blood urea nitrogen and reduced urine output (Rabindranath, Adams, MacLeod and Muirhead, 2007, p…
The discovery and isolation of stem cells proved to be a in the history of molecular biology, and the medical sciences that they inform. In addition to the obvious advantages of providing a clear model for embryonic development, the discovery of stem cells is also a crucial milestone for genetic manipulation.
Thanks to unconventional medical procedures, altering one’s innate characteristics, viz., gender, genetic makeup, physical appearances, etc., is not impossible anymore. One of the most significant advances of medical sciences is in the field of Hormonal Replacement Therapy (HRT).
The disease results from the gradual and in many cases permanent dysfunction of kidneys for a certain period of time depending on the health status, lifestyle and other factors that affect the individual at the time. It is also called the kidney failure. When kidneys fail to function in this manner, there is an accumulation of wastes in the body; water is not fully utilised; and other toxic materials are not excreted from the body system as should be in a normal case.
Title: Essay 2 – Renal (Human Physiology and Anatomy) Introduction: The kidneys represent important organs in the body of human beings. It has the responsibility of urine preparation, thereby allowing toxic substances and water to get removed from the body.
The two types of dialysis include the peritoneal and the hemodialysis. The peritoneal dialysis uses the peritoneal cavity in the filtration process whereas in hemodialysis, the filtration process occurs through the dialysis machine. Both methods are beneficial for patients and depending on recommendations of medical practitioners, the appropriate method of dialysis can be used for the patient.

While the existence of hormone replacement therapy provided the cure for dwarfism, the most common result of a deficiency of somatotropin, it has also given an insight into the effects of the human growth hormone in the process of aging.
A study focusing on the levels of growth hormone in relation with age was performed Russell-Aulet et al.
, intraosseous (IO) vascular access is a recommendable procedure as an alternative in emergency scenarios (Sachdeva and Dutta 2012) if timely venous catheterization is impracticable. The purpose prompting research is to analyze the applicability of IO usage in emergency cases.
the treatment can also be done on aging for example hormone replacement therapy (menopause), testosterone replacement in males with low levels due to disease or aging. Another area where hormonal therapy is used is on sex reassignment for instance; hormonal replacement therapy
The author states that the advantages of hormone therapy are dictated by the mode of administering the medicines: whether it is systemic or low-dose use of estrogen. On the one hand, systemic hormone therapy pills containing estrogen, balm or spray, and skin patch continues to be the most appropriate treatment for symptomatic hot flashes.
