In order for a synovial joint to perform its best it works as a team. After all we know that when you work with a team things get done a lot more efficiently and less work gets put on one single person. In this case the synovial joint is surrounded by the following structures: Tendons which attach our muscles to the bone, ligaments which attach bone to bone, Bursae, which are small sacs of extra synovial fluid that provide extra cushion and protection to the synovial joint. These structures help…

Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart. The path of a RBC consist of it first beginning in the heart as the RBC transports oxygen into the aorta by the aortic valve through contracting of the left ventricle. From the aorta, the RBC then travels through an artery with the help of arterioles to reach the capillaries. When in the capillary, the oxygen molecule that is carried by the RBC then detaches and travels through the capillary into…

Experimental Design: We will determine the effect of HIV-1 Tat on the antibody type and production in response to influenza vaccine. We chose influenza vaccine and pneumococcal vaccine to differentiate the effects between T cell dependent and T cell independent humoral responses. These are also suggested to individuals who are immunocompromised, especially people infected with HIV-1. For this purpose, C5BL6/J mice will be treated with HIV-1 Tat for one dose a week until 3 weeks. On week 4, all…

Introduction The Central Nervous System (CNS) has been considered devoid of lymphatic vasculature, and for years, the theory of the nonexistence of the lymphatic system in the brain has been accepted as a biological/anatomical fact. This very basic fact of neuro-anatomy has recently been upset by two independent studies, revealing that the brain does, in fact, have a functional lymphatic system. Although this study was originally done on mice brains, there have been similar findings in human…

Immunotherapy. There are also many side effects of these treatments that include hair loss, the outlook on a patient with Neuroblastoma would be based on the stage and risk level of the cancer. The risk levels would include the stage of cancer, tumor histology, tumor biology, and age of…

Requirements An entry level as a zoologist requires an undergraduate degree in zoology or closely related fields like wildlife biology.This academic program involve coursework in natural sciences, animal anatomy, ecology, invertebrate zoology, histology, and animals structure and function. Upper level courses allow for specializations in genetics,parasitology, and cytology. If your career goal is to to be a manager or researcher, you will need to pursue an advanced degree in zoology and…

shows atypia and high mitotic index and has increased expression of P53 and bcl-2, not shown by benign glomus tumor cells [6]. On the contrary, de novo glomangiosarcoma is more difficult to diagnose because of the absence of benign glomus tumor histology, and can be easily confused with other sarcomas. Immunostaining is helpful in the diagnosis as tumor cells are typically positive for smooth muscle actin and vimentin but negative for epithelial, vascular and neural markers (i.e. desmin,…

alternatives, the small spaces and narrow anatomical boundaries must be kept in mind when deciding on the treatment method and when counseling patients. For a long time, surgical removal was the standard of care, independently of the size, location or histology. However, due to the anatomical limitations, neurosurgical intervention may bear the risk of significant side effects. Over the last decade radiation therapy (RT) has become a valid treatment alternative for the treatment of meningiomas.…

of lymphangiogeneis. The development of small lymphoid vessels is deficient around small biliary tracts and in general. People experience jaundice soon after they are born, and edema of the legs was caused by hypoplasia of the lymphatic's. Liver histology showed giant cells transformation in infancy, and some fibrosis or cirrhosis in later childhood. Image result for aagenaes…

Dimorphic fungi can switch between yeast and mold forms to suit pathogen colonization. The mold form is nonpathogenic and found in the environment so transmission by spores is possible. Once inhaled, the spores convert into the yeast form and become pathogenic within the host. Common dimorphic fungi include Blastomyces, Coccidioides, and Histoplasma (31). This patient has a disseminated form of Histoplasma capsulatum var capsulatum. Histoplasma is the most common dimorphic mycoses that can cause…
