Cystoscopy and Standard TURB are still the gold standard procedure for the diagnosis and initial treatment of NMIBC. TURB has been carried out by using the monopolar resectoscopes. Recently, the bipolar resectoscopes, which is used for transurethral resection of the prostate, was introduced for the treatment of bladder cancer. Several advantages are associated with the use of bipolar technology: the fluid of irrigation is a saline solution, so reduction of morbidity due to the TUR syndrome, especially in the procedure of long duration (>90 min). Furthermore, in the conventional monopolar (mTUR), in this system the active electrode is represented by the resecting loop, and the return electrode is a pad placed on the patient’s surface resulting in the energy travels a considerable distance along the body to complete the circuit (1,3,7). Controversy, bipolar system (bTUR) has been used an active and return electrode in close to each other at the level of the target tissue, so limiting the distance for the energy to cross, thus reducing the morbidity of patients, specially patients with an implanted pacemaker or cardioverter defibrillator that do not need to be deactivated (8,9). Plasma Kinetic (PK) generator and specific instruments are designed as a system, which uses high-powered pulsed bipolar energy to produce a plasma kinetic field around the working elements and is designed to produce a temperature that allows effective tissue dissection but result in minimal…

What is Downs Syndrome? Downs Syndrome (DS) is the leading form of intellectual and chromosomal deformity (Sherman et al., 2007), affecting approximately 1 in every 700 babies born each year (Parker et al. 2010). The main physiological aspect and cause of DS is the trisomy of chromosome 21 in which the usual paired chromosome becomes a trio (Patterson, 2009). DS also has a clear clinical presentation from birth with a number of distinct symptoms such as (percentages represent number of DS…

Histological analysis Tissue harvested from the distal colon (1 cm from the rectum) was cut into segments, fixed with 10% formaldehyde overnight, embedded in paraffin, sectioned at 5 μm, mounted on clean glass slides, and stained with hematoxylin and eosin (H&E) for histological evaluation. Each slide was coded and analyzed in a blinded fashion by two investigators using light microscopy. Each sample was assigned a histological score based on cumulative scores assigned to colon characteristics…

For a histology lab to be safe and secure there are many activities and procedures that have to be adhered to and evaluated. A majority of issues which occur within a histology lab are most likely to be those about incidents linked to the equipment used, hazardous chemicals, bio hazardous materials used and general risks such as electrical or fire hazards. I am going to discuss the best possible ways to make sure that quality performance within a histology lab, in relation to health, safety and…

Vertebrate Histology (BIOLOGY 364) Fall 2015 Lecture Final (Take-home) A. Pick 3 of the following and argue that the following are either “adaptive” or necessary for survival, homeostasis, and/or reproduction: 1. Adluminal compartment of seminiferous tubules • The adluminal compartment is made up of spermatocytes, spermatozoa and spermatids. The compartment is considered a tight-junction. This tight-junction is said to be a blood-testicle-barrier. This means the…

definitive diagnose is made: liver histology, serum biochemistry, serum immunoglobulins, serum antibodies, viral markers, and other etiological factors (Manns, et al., 2010). In order to earn a definite diagnosis, versus a probable diagnosis, all standards of each of the six aforementioned categories must be met. The liver histology must present necrosis of at least moderate activity regardless of lobular hepatitis or central-portal bridging necrosis, but without biliary lesions or well-defined…

a pre-med track, I have covered a wide range of courses such as chemistry, physics, biology, and various neuroscience classes. I have spent three years as a research volunteer at Texas Biomedical Device Center Neuroscience Cortical Plasticity Lab. We have developed a therapy to help brain injury patients fully reengage in life. For the past several years, we have performed research on how vagus nerve stimulation helps patients recover from disorders such as tinnitus and chronic pain, stroke,…

of the child with cancer. Cancer patients are placed in risk groups after they have been diagnosed with a stage of cancer, which is usually after surgery. There are three risk groups: low risk, intermediate risk, and high risk. Low risk patients are children with stage 1 and children with stage 2A or 2B that have no more copies of the cancer causing gene. Children that are classified as stage 4S that have supportive histology and no more copies of the cancer causing gene are also categorized…

Doctors then revealed a thigh melanoma, a mid-back melanoma, and a right deltoid melanoma. Immediate excision biopsies were performed in order to remove the melanomas. The patient also contracted an acute lymphadenopathy. A lymph nodes biopsy was performed using two techniques: gamma probe and patent V blue dye. From these dissected lymph nodes, scientists discovered a black and blue pigment focus posing as another melanoma (Fig. 2). An urgent histology review was performed and revealed that it…

time, and the different paradigms, I would have liked for him to go into further detail regarding scientific data about the cellular composition of the tissues found on the fossil. In order for me to fully understand a concept, I have to learn the minute details before understanding the “big picture”. In Mary Schweitzer’s Soft- Tissue Vessels and Cellular Preservation in Tyrannosaurus Rex, Schweitzer explains the histology of the tissues found on fossils, which helps me to understand this…
