Introduction Orthodontic treatment has been a very popular option used in restoring both function and esthics. A high surge of these treatments has been increased 100% in fold since 1982 [ortho1]. Most orthodontic patients that seek treatment have been between the ages 6-18 years, estimated to be four million, whereas one million adult patients seek orthodontic treatments in North America [ortho1]. There is an estimated 17-43% of objective juvenile patients in need of orthodontic treatment…

Phosphatase and Tensin Homolog is also known as PTEN, it is a phosphates encoding gene. PTEN gene is located on the long arm of chromosome 10 at the position 23.3. PTEN was first discovered in 1997, and it is a tumour suppressor gene (Li & Sun 1997, Li et al. 1997, Steck et al. 1997) it helps to regulate cell division. They function as a lipid phosphates to regulate signal transduction pathways, such as the phosphoinositide 3-kinase (PI3k), protein kinase B (AKT) . The activity of its lipid…

flexibility. He then used sol-gel technology to prepare silicone-modified polyester resin. The properties of the coting film, such as hardness, flexibility, solvent resistance and adhesion were studied and optimized. When compared with commercially available coloured polyester coating SM 3911, the flexibility, adhesion, rigidity , MEK resistance and acid-resistance of the prepared coating were found to be excellent. Bekemeier Thomas et.al, 2013 also studied effect of silicone and polyester…

Observing at Arkansas Children’s Hospital is a day that I will never forget. At Children’s I was placed in the Emergency Department where I got to see and encounter many different patients, including a home trachea patient with croup, patient with deep lacerations to the forehead, a downs patient with undiagnosed diabetes, etc. While in the emergency department I got to witness firsthand how the doctors, nurses, and respiratory therapist really work together, and that their primary focus is…

Plumbing emergencies can happen any time, any place. A pipe leak turns into a spray. A crack appears on a pipe joint. A faucet becomes a water fall. And, as many homeowners and business owners will tell you, those kinds of emergencies seem to happen on long holiday weekends or in the middle of the night. There are times when you need to make an emergency plumbing repair to prevent major damage from occurring. Putty is a great choice to get a leak under control. How to Make an Emergency Repair…

Besides, the obstruction can also occur outside of the ventricles in the subarachnoid space as a result of debris or adhesions from a prior hemorrhage, infection, or inflammation (Blumenfeld, 2010 p. 156). A decrease in CSF absorption can also cause hydrocephalus when arachnoid granulations are damaged or clogged, but this can be hard to distinguish from obstruction of…

with secondary amenorrhoea is by challenging the endometrium with progestin. A positive progestin challenge (i.e. presence of withdrawal bleeding after progestin administration) indicates functioning endometrium, thus ruling out the possibility of adhesions in the uterine cavity…

Hysterectomy: Purpose, Procedure, and Risks Hysterectomy is a surgical procedure to remove a woman’s uterus. Removing the uterus means that you can no longer become pregnant or menstruate. It is one of the most common gynaecological operations. Your doctor might suggest a hysterectomy if you are suffering from any of the following conditions: • Uterine fibroids .This is the most common reason for hysterectomy. • Endometriosis • Adenomyosis • Pelvic support problems (such as uterine prolapse…

The major problem associated with chemotherapeutic agents is their lack of specificity and selectivity. This is mainly due to the presence of very subtle metabolic differences between the tumor cells and the normal cells[51]. Hence, very large doses of chemotherapeutic drugs are required for successful chemotherapy. Furthermore, cancer chemotherapy leads to severe adverse effects, such as hair loss, damages to the liver, kidney, and bone marrow, as the normal cells are also exposed to these…

Since the development of direct orthodontic bonding, various new developments have been made to help improve the technique. These developments have focused on improving bond strength, decreasing bonding time, reducing the number of bonding steps, and decreasing adhesive remnants. All these advances have worked towards creating the most efficient bonding protocol while maintaining enamel health during treatment and after debonding. As newer and more efficient products are marketed, we must also…
