...Osteoporosis Research Paper Ericson Yabut Anatomy and Physiology 200A Dr. Edward Eivers 2/14/16 Introduction: Normal Physiology of the Bone It is important to know the fundamental aspects of the skeletal system and the normal anatomy and physiology of the bone tissue in the system to understand osteoporosis. The skeletal system of the human body is essential in many functions, such as supporting body structure, storing minerals and bone growth factors, and being used as leverage for skeletal muscle locomotion. The skeletal system used to be made of hyaline cartilage, but the cartilage eventually ossifies into bone tissue as the body continues to age develop into adulthood. Bone growth and development is strongly affected by...

...The paper by Aoba and Fejerskov written in 2002 talks about a hypothesized mechanism being a dose-related disruption of the mineralization which causes the teeth to become porous with a decrease in proteins. This degradation of the teeth is thought to be from a breakdown of the matrix proteins and the way the by-products are drawn out from the aging enamel (Aoba and Fejerskov, 2002). There are different forms categorizing the severity of enamel fluorosis. Mild enamel fluorosis is seen as white striations or opaque patches while in moderate or severe cases the opaque spots extend and the porosity increases (NRC Ch.6,1993). If the damage is severe enough there can be many dental health issues, including an increase in caries later in life. These...

Though the disease is somewhat unknown and presumably hereditary, the uncovered cause and criteria for diagnosis is linked through like antibodies and antigens (http://www.nejm.org/doi/pdf/10.1056/NEJM197611182952101). MCTD affects numerous body systems i.e. skeletal, muscular, skeletal, digestive, and nervous (https://my.clevelandclinic.org/health/diseases_conditions/hic_Mixed_Connective_Tissue_Disease). Treatment for this disease is patient specific depending on the severity of each case; while the medications prescribed are ailment specific, creating a huge risk of developing side effects due to contraindications and normal use. In diagnosing these side effects, one must first explore the history of MCTD. What is Mixed Connective Tissue Disease (MCTD)? In 1972 (Venables) Mixed Connective Tissue Disease (MCTD) was first recognized for its overlapping features by its like or “mixed” similarities noticed in patients presenting with signs and symptoms of three autoimmune connective tissue diseases. The like featured diseases that make up Mixed Connective Tissue Disease (MCTD) are systemic lupus erythematosus (SLE) (an autoimmune disease where healthy tissue is mistakenly attacked by the body’s immune system), systemic sclerosis (characterized as both an autoimmune and connective tissue disease that primarily thickens the skin through a buildup of collagen while...

...naturalness have spawned many applications in exploring large and complex data, computer games, virtual reality, health care, etc. Although the market for hand gesture password is huge, building a robust hand gesture recognition system remains a challenging problem for traditional vision-based approaches, which are greatly limited by the quality of the input from optical sensors. In this paper, we use their gesture in order to login or authenticate to the system. And then we introduce a novel method to create a gesture pattern that act as a password. This hand gesture recognition system performs robustly despite variations in hand orientation, scale or articulation. Moreover, it works well in uncontrolled environments with background clusters. Key words: Password Recognition, Authentication, Gesture password INTRODUCTION The advent of relatively cheap image and depth sensors has spurred research in the field of object tracking and gesture recognition. One of the more popular devices used to do this type of research is Microsoft’s Kinect, which has sensors that capture both rgb and depth data. Using similar data, researchers have developed algorithms that not only identify humans in a scene, but perform full body tracking; they can infer a person’s skeletal structure in real-time, allowing for the recognition and classification of a set of full...

...Anatomy and Physiology 2, SCI 136 Research project # 40904000 Muscular Dystrophy Definition Muscular dystrophy (MD) refers to a group of more than 30 genetic diseases that cause progressive weakness and degeneration of skeletal muscles used during voluntary movement. The word dystrophy is derived from the Greek dys, which means "difficult" or "faulty," and troph, or "nourish." These disorders vary in age of onset, severity, and pattern of affected muscles. All forms of MD grow worse as muscles progressively degenerate and weaken. Many patients eventually lose the ability to walk (“National Institute,” 2011). Some types of MD also affect the heart, gastrointestinal system, endocrine glands, spine, eyes, brain, and other organs. Respiratory and cardiac diseases may occur, and some patients may develop a swallowing disorder. MD is not contagious and cannot be brought on by injury or activity (“National Institute,” 2011). Method(s) of diagnosis Muscular dystrophies are diagnosed through both the patient’s medical history and a complete family history to determine if the muscle disease is secondary to a disease affecting other tissues or organs or is an inherited condition. It is also important to rule out any muscle weakness resulting from prior surgery, exposure to toxins, current medications that may affect the patient's functional status, and any acquired muscle diseases. Thorough clinical and neurological exams can rule out disorders of the central and/or...

...experiments conforming to strict criteria for calibration and penetration the estimated mean [Mg]i was 04 mmol/l. This is to be regarded as an upper limit since it was estimated by linear extrapolation of the calibration curve. INTRODUCTION Ionized Mg plays an essential role in the regulation of a large number of cellular functions. It is a co-factor in many enzymatic reactions, influences tension development in muscle and modulates amongst others the ionic transport systems in mitochondria (see reviews by Gunther, 1977; Shine, 1979; and Ackerman & Nicholls, 1983). Despite its importance in cellular mechanisms, estimations of the free Mg ([Mg]i) by various methods range from 0- 1 mmol/l to 6 mmol/l (reviews: Flatman, 1984; Gupta, Gupta & Moore, 1984) mainly because of the lack of a simple direct method for its measurement. Direct measurement of [Mg]i is now possible using micro-electrodes filled with the Mg resin described by Lanter, Erne, Ammann & Simon (1980) and measurements have been carried out in both cardiac and skeletal muscle (Hess, Metzger & Weingart, 1982; Lopez, Alamo, Caputo, Vergara & DiPolo, 1984), and in nerve cells of Helix aspersa (AlvarezLeefmans, Gamifno & Rink, 1984). This resin has however, the disadvantage that...

...key gene to the human reproductive system. It plays a vital role in the development of important sexual organs. Along with the other hedgehog proteins, the hedgehog protein family and signaling pathway are also important to the overall development of many parts and systems of the human body. Each protein within the family has its own role to play in overall expression of cells and growth. There are a total of three proteins within the family; the Indian hedgehog (IHH), the sonic hedgehog (SHH), and the desert hedgehog (DHH) gene. The term hedgehog refers to the terminal domains within the genes of this family. The “hog” domain makes up the C-terminal of the gene and the “hedge” domain makes up the N-terminal of...

...Does Race Exist? * Posted 02.15.00 * NOVA The concept of race is one of the most intellectually and emotionally charged subjects, not only in society but in science as well. NOVA Online asked two leading anthropologists, Dr. Loring Brace of the University of Michigan and Dr. George Gill of the University of Wyoming, who fall on either side of the debate about whether race exists in biologic terms, to state their points of view. Regardless of where you stand on the issue, we think you will find their arguments well-reasoned and thought-provoking. Loring Brace and George Gill come down on different sides of the question Does race exist biologically? Read their viewpoints here. EnlargePhoto credit: © andipantz/iStockphoto AN ANTAGONIST'S PERSPECTIVE by C. Loring Brace I am going to start this essay with what may seem to many as an outrageous assertion: There is no such thing as a biological entity that warrants the term "race." The immediate reaction of most literate people is that this is obviously nonsense. The physician will retort, "What do you mean 'there is no such thing as race'? I see it in my practice everyday!" Jane Doe and John Roe will be equally incredulous. Note carefully, however, that my opening declaration did not claim that "there is no such thing as race." What I said is that there is no "biological entity that warrants the term 'race'." "You're splitting hairs," the reader may retort. "Stop playing verbal games and tell us what you really mean...

...Carla Paula Tantay May 24, 2015 HCA/220 Seven Organizational Approaches Paper Instructor: Terrasha Rachels There are 7 organizational approaches to studying the human body. The seven organizational approaches consist of planes and directions, body cavities, quadrants and regions, anatomy and physiology, microscopic and macroscopic, body systems and medical specialties. The body planes and body direction is the division of the body in to sections from front to back, right and left, and top and bottom. These sections are called the mid sagittal plane, the coronal plane, and the transverse plane. There are two main cavities; “Dorsal and ventral body cavities”. Based on Bite Anti Body Research, Some anatomical references do not recognize the dorsal body cavity but we will use it in this example because it is use by some professionals and colleges. Dorsal body cavity protects organs in our nervous system and dorsal body cavity has 2 divisions which is cranial which works around the brains and spinal which works around the spinal cord. With Ventral the superior division is called the thoracic cavity. The thoracic cavity is surrounded by the ribs and muscles in the chest. It’s further subdivided into lateral pleural cavities (each pleural cavity envelopes a lung) and the mediastinum. Within The pericardial cavity lies within the mediastinum. Quadrants are divides our bodies into regions for diagnostic and descriptive purposes. The quadrants are defined by drawing an imaginary...

...Stem cell research is one that is widely debated amongst various religions, cultures, and political groups. The question as to when life actually begins is the epicenter of this worldwide quarrel, and may not be settled for some time. Although this may be true, one fact that cannot be denied is that stem cell research has led to many life saving discoveries in various sectors of scientific research. In regards to the ethical dilemma of stem cells, recent developments in induced pluripotent stem cells (iPSCs) have made it possible to explore the applications of stem cells while avoiding the ethical problems associated with embryonic stem cell research (Seki & Fekuda, 2015). One intriguing area in stem cell research is the potential applications for them in the treatment of cardiac diseases. Studies have explored the potential uses for stem cells for the treatment of heart disease (Yamakawa & Ieda, 2015). Additionally, stem cells have been explored for the treatment of heart failure and myocardial infarction (Rasmussen, et al., 2013). Stem cells and how they may be used for the treatment of various cardiac diseases is an exciting topic and has the potential to change future approaches to the treatment. This paper will examine the applications and significance of stem cells in relation to these common cardiac pathologies. Heart disease is one of the leading causes of death in developed countries and currently there are few effective treatment options available (Yamakawa & Ieda...

...involve labour of the workers to put in place the materials as per the design are it mixing, lifting and placing them in place, installation, delivery and storage of the materials. Material handling can be by machines/equipment or directly by the workers themselves. Handling and storing materials involves many different activities such as hoisting, manually carrying bags or material and stacking supplies. Employees can be injured by improperly lifting materials (manually and by machine), falling objects and improperly stacked supplies. This paper concentrates on the human ability in the movement and placement of materials and other facilities as work progresses on site. An examination of activities on an active site have been undertaken to inform this paper on the practicability and applicability of researched theories relating to human lifting capability on site. The following sites have been examined and findings discussed later in this paper: • Proposed Primary Security Screening Facility - JKIA Nairobi • Construction of a Terminal Building at Isiolo Airport • Crescent residential apartments in Kileleshwa • Riverside place apartments in Lavington. The human aspect on sites being examined relates to the handling of materials and other facilities on site. It is noted that manual handling involves activities that...

...currently found in the literature can be explained by a lack of standards related to at least 3 topics: 1- motion representation; 2- selection of anatomical landmarks (ALs); 3- software resources. This literature discrepancy should be greatly reduced if a consensus on the three above points could be reached. Topic 1 is tackled by the International Society of Biomechanics (ISB) that published Standards to define body segment orientations and clinically meaningful motion representation (Wu, 1995; Wu, 2002; Wu, In Press). Efforts related to Topic 2 are currently undergoing to allow strict AL selection necessary to build anatomical reference frames in a repeatable way (Van Sint Jan, In Press). Topic 3 is the goal of this paper. The presented research aimed to propose a software interface that would allow a user to: -interactively import motion data; -to register the motion to 3D bone models (if necessary); -to select ALs; -and to create motion representation graphs according to standards. Similar commercial tools are available, but they are unfortunately often costly and limited to a few motion representations.
