Water is essential in keeping the body in balance. There are two significant compartments of the body that exchange fluids and electrolytes to maintain homeostasis, which are intracellular and extracellular. These two spaces continually interchange electrolytes, particles, and water to sustain the same pressure. (PP chap42 pg935) This paper will describe three machinimas that assists in maintaining homeostasis, four main categories of IV therapy, and nursing consideration in relation to infusing IV. There are many methods the body uses to retain equal pressure between the intracellular and extracellular compartments. The body has many mechanisms to maintain fluid balance between extracellular and intracellular compartments. The only…

In order to determine the extent to which the reversal potential for potassium determines the resting membrane potential of a given cell, a mechanism is needed to determine the change in membrane voltage across the cell in different extracellular potassium solutions. The intracellular recording technique consists of puncturing a prepared cell with a conductive pipette. The difference in potential between the extracellular electrode and the wire in the pipette is recorded and displayed on the…

increases the person’s risk of fracture, a hunched forward posture, and chronic back pain. More than 200 million people in the world suffer from osteoporosis. Between 1990 and 2000, an increase of almost 25 percent in hip fracture cases worldwide. Experts estimate that incidence of hip fracture will increase by 310 percent in and 240 percent in women by 2050. In the new study, the researchers used the supercomputers Comet at the San Diego Supercomputer Center and Stampede 1 at the Texas…

CDH2 CDH2 gene codes for the protein N-cadherin, also known as Cadherin-2 (CDH2), or neural cadherin (NCAD). Studies on this gene has discovered that it is located on Chromosome 18-NC_000018.10, assembly GRCh38.p2 on humans, and contains 20 exons.(9) N-cadherin is one of the classification of the cadherin superfamily, and is composed of five extracellular cadherin repeats, highly conserved cytoplasmic tail and a transmembrane region. This protein’s purpose is to mediate cell-cell adhesion by…

and extremities. Hypertrophic scars are frequently misdiagnosed as keloids clinically . Their gross appearance is similar, although keloids grow beyond wound margins. KELOIDS Keloids represent a pathological response to cutaneous injury resulting in disfiguring scars with no known satisfactory treatment (Figure 1). Skin injuries such as burns, inflammation, surgery or minor trauma,insect bite induce an overabundant ECM deposition, especially collagen41. Even the spontaneous development of…

myocardial infarctions. Although this critical effect was infrequent, evaluating why five patients in the treatment groups experienced myocardial infarctions, in comparison to only one in either of the placebo groups, may be an important area of focus for future research (Richeldi et al. 2014). The effect of nintedanib in primary human lung cells obtained from IPF patients were studied in vitro. Fibrotic cells were isolated from lung biopsies of 4 patients diagnosed with IPF and non-fibrotic…

The fibroblasts proliferate and synthesize and secrete proteins such as types of collagen during the phase of healing Hemostasis and degeneration. The function of these proteins is to reconstruct the extracellular matrix and provide a scaffolding- like framework for the developing endothelial and parenchymal cell. It is a t the point that this proliferation and migrations occurs as epidermal skin cells in the top layer move down the sides of the wound to help fill the gap. Fibroblast move in…

About 20% volume of the mammalian central nervous system comprises of an extracellular matrix that includes proteins, proteoglycans, and glycosaminoglycans (Bignami A et.al 1993). Evolving evidence indicates that the organization and composition of this matrix change throughout the course of normal aging, during neurodegenerative diseases and following central nervous system injury and that these modifications influence a diverse range of cellular behaviors. The central nervous system…

When a wound’s edges are close together a clot forms. Clots contain fibrin which is a protein that connects the edges of the wound and stops the bleeding. Once a clot has formed and dried it becomes a scab that seals and protects the wound from germs. Epithelium on the edges of the wound goes through regeneration, a process in which new cells of the same function and structure are formed; as the inflammatory responses proceed, epithelium forms under the scab as well. Eventually the wounds edges…

1. What is the difference between calcium carbonate and hydroxyapatite? Calcium carbonate is more soluble than hydroxyapatite. 2. What are the pitfalls of using CHA in bone graft procedures? CHA is fragile an brittle and it should only be used temporarily 3. What is CHACC and what potentially makes it better than CHA? CHACC is Coralline Hydroxyapatite/calcium carbonate. CHACC is better than CHA because it can keep a porous structure as well s biocompatibility making it a even better…
