This document is a project proposal for the development of starch-based hemostatic products. Acknowledgement. Much thanks to the project supervisor who offered guidance in every step of the development of this proposal. Developing starch based hemostatic products Project summary. Purpose: This proposal is envisioned to develop a hemostatic agent from purified plant starch. In this case, the product of the reaction should be developed by the formation of microporous hemosphere particles after etherification, esterification and crosslinking of glucose molecules to form ethyl propanetriol (glycerol-ether links (1-3 deoxy propanol)). The second intention of this study is to investigate the properties ...

Organization:

The human body is home to a variety of organisms ranging from the minute bacteria to eukaryotic mites. Demodex folliculorum is a small arthropod that lives in human hair follicles and sebaceous glands. D. folliculorum and the closely related D. brevis live in a commensal relationship on humans and are harmless in the normal course of events. Demodex was first discovered by Henle in 1841 and described by Simon Akbulatova in 1842. The existence of the mite in cadavers was established by Stcherbatchoff in 1903 and later by Gmeiner in 1908. Riechers and Kopf in 1969 showed that maximum ...

Vanishing Twin Syndrome

Vanishing Twin Syndrome In 1945, Walter Stoeckel proposed that the general population of conceptions were higher for multiple fetuses that supposed, suggesting that a twin or multiple fetuses may die in utero and subsequently be reabsorbed without clinical evidence by the surviving fetus/es, mother, or placenta (Stoeckel, 1945, cited in Levi, 1976). Named the “vanishing twin syndrome”, the cause is generally not known. If abnormalities are determined, they appear related to early development and are chromosomal; improper implantation of the cord may also play a role. This paper presents a brief overview of the etiology, demographics, consequences, and tests ...

Introduction

The skin is an essential organ in the human body made of a complex membrane of cells, tissues and pigments that hold the body together. Similarly, the skin color is determined by the amount of melanin, the location of melanin and melanocytes, and the presence of caretenoids (Ostler, et al., 2004). Further, the ratio between oxygenated blood and hemoglobin and exogenous or endogenous pigments, also affect the skin color. Melanin is a vital tissue in the skin and the malfunction of melanocytes system, can lead to pigmentation disorder (Rose, 2009). The malfunction of melanocytes system can amount to melanocytic nevi, a ...

Experiment: Investigating the integumentary system.

Introduction Scientifically, the integumentary system consists of the skin and its appendages. It functions primarily as an outer protection for internal organs from bacteria. Superficially, the skin serves as a buffer to trauma. Its integrity decreases incidences of invasion by harmful organisms even when breakage occurs. (Martini 2009). Beside these basic functions, the integumentary system is also responsible for insulation by assisting in regulating body temperature; production of hair; excretion of waste through pores and a sensory station for the transmission of impulses when touched. Sensory receptors present within the subcutaneous layers are also pain transmitters. (Watson 2011)
