Use of Cells as Replacement Tissues and Organs

- Cultured cell from animal tissue can be used to replace dysfunctional and dead tissues and organs. In our daily lives, our cells are damaged and some of the damaged cells are repaired, but others are destroyed. The destroyed cells are forced into dysfunctional state where it can no longer be divide and undergo apoptosis (Sens Research Foundation, 2014). Some of the lost cells can be replaced by tissue-specific stem cell but due to aging process, the stem cell becomes less effective, losing cells progressively and they are increasingly become malfunctioning....   [tags: cultured cells from animal tissue]

The Transplantation of Organs and Tissues

- Medicine has made great strides in the past few centuries. One such advancement is the transplantation of organs and tissues. Those who receive transplants are often times patients with fatal diseases, and these transplants give them a second chance at life. Unfortunately, the number of people needing a transplant is growing more rapidly than available organs; statistics say that in the United States, seventeen people die daily while hoping for an organ transplant (Friedman & Friedman, 2006). Laws restrict transplantable organs to those organs that are donated; the donor must be of sound mind and be a minimum of eighteen years of age....   [tags: buying and selling organs]

These properties allow for the joint to move as necessary; however, maintaining the bones alignment and preventing dislocation (Toole, Toole and Toole, 1999). Tendons are another connective tissue and connect muscle to bone and are not elastic or able to stretch.

How Do Oral Hard Tissues React to Intraosseous Implants?

- How do oral hard tissues react to intraosseous implants. The introduction and growing popularity of intraosseous implants has revolutionised restorative dentistry. Successful implants restore complete function to patients in areas of previously missing teeth. Although they may act like teeth, the histological hard tissue reaction to implants is a wound healing process compared to the developmental process involved in natural dentition. In addition, the healing process may vary from case to case depending on factors such as the implant material, surface texture, clinician handling and placement into the peri-implant tissue; all of which will be discussed in the following paper....   [tags: teeth, implants, placement, tissue]

- Bioethics: Abortion and Fetal Tissue Research In the United States, about half of pregnancies among American woman are unintented, and four in 10 of these are terminated by abortion (Induced Abortion in the United States). But if it were not for these aborted fetuses, vaccinces for rubella and varicella would have never been able to be created and save millions of lives today (ASCB). So the ethical question health care professionals face today is, Abortions: Is it Murder or A Savior. Abortion is when a pregnancy is ended to prevent the birth of a child....   [tags: Abortion, Pregnancy, Fetus, Fertility]

Organ Donation And Tissue Donation

- 18 year old, Domonique Smith, also called Nikki, was lying in an ICU hospital bed fighting her last battle. Before Nikki knew she wasn’t going to live much longer, she had a conversation with her mom, telling her she wanted to be an organ and tissue donor. Once Nikki passed away, her heart was transplanted into her life-long friend, Tanisha Basham, through a process called directed donation. Along with Tanisha, Nikki helped three other people, so she saved four people’s lives (Marketwire). According to Gift of Hope Organ and Tissue Donor Network, 2015 was a better year than any other for saving lives through organ and tissue donation....   [tags: Organ transplant, Organ donation, Heart, Organ]

The Cloning, Characterization, And Tissue

- We describe the cloning, characterization, and tissue distribution of the two human peroxisome proliferator activated receptor isoforms hPPARg2 and hPPARg1. In cotransfection assays the two isoforms were activated to approximately the same extent by known PPARg activators. Human PPARg binds to DNA as a heterodimer with the retinoid X receptor (RXR). This heterodimer was activated by both RXR agonists and antagonists and the addition of PPARg ligands with retinoids resulted in greater than additive activation....   [tags: Molecular biology, DNA]

The Use of Human Tissue for Research

- One of the most versatile and dynamic substances used by researchers and doctors is also the most ubiquitous: human tissue. Donated tissue samples are used many different ways, from basic study to advanced testing. Scientists can better understand the disease process by observing it at a cellular level. Drugs can also be tested and refined on tissue samples. Some of the more important areas of study include cancer, diabetes, liver disease, stroke and Alzheimer's disease. It is also used to help develop diagnostic tests, so that doctors can detect disease less invasively, during a routine office visit....   [tags: pharmacology, regeneration, future ]

Benefits Of Donor Tissue And Save Lives

- Introduction The worldwide demand for cells, tissues and organs for transplantation far exceeds supply. People are dying while on waiting lists for transplants. Several ways to provide more donor tissue and save lives are being investigated including changing donation systems and legislation, sourcing tissue from animals and stem cell therapies (The University of Waikato, 2011). Each country has its own organ donation system, rules and regulations. Some systems may result in more donors than others, but ultimately, donation rates are strongly influenced by peoples’ cultural, spiritual and religious views (The University of Waikato, 2011)....   [tags: Organ transplant, Organ, Skin, Human]

Epithelial Tissue

- Every organ in the human body is composed of one or more tissues. The study of these tissues is known as histology. It is because of histology that the structure of organs can be researched and understood. Since organs are composed of tissues, it is important to understand each tissue type, their structure, their location, and their functions to better understand how each organ operates within the human body. Tissues are composed of groups of cells that have similar shapes and functions. There are four main types of tissue found in the human body: epithelial tissue, connective tissue, muscular tissue, and nervous tissue....   [tags: Biology]

Tissue in the Human Body

- Connective Tissue Connective tissues are found all over our bodies. Generally, they are located in blood, fat, and between muscles and bones. The matrix is the substance that surrounds the cell. Matrices can be fluid or solid, depending on where they are found. They also are found to have varying degrees of vascularity. For example, a bone would be very vascular while cartilage is avascular. Two good property the cells of connective tissue have is that they can divide and repair themselves. The functions of these tissues are: to bind structures, support, protect, serve as framework, store fat, produce blood cells and repair damage....   [tags: Biology]

Muscle And Its Effect On Tissue Stress

- Muscle activity, including generating force and moving limbs through lengthening and shortening, is an important influence on beneficial tissue stress. Muscles adapt quickly to periods of lower or higher stress and demonstrate obvious visual and functional changes. At a tissue level, the Physical Stress Theory (PST) states that muscle adaptations are consistent with other high and low strain tissue adaptation models. Low stress/activity associated with immobilization results in decreases in contractile protein, fiber diameter, peak tension and power....   [tags: Muscle, Muscle contraction, Muscular system]
