    and are likely to be compromised by the risk factors above and as well as age and comorbidity. In addition, poor circulation can be a complication of the OREF surgery. Pins used in external fixation may injure vessels by directly piercing or resting and eroding the vessel wall. According to Lim et al (2010), vessel injury is secondary to indirect compression and impingement, direct or partial laceration and erosion. As a result, the patient may experience bleeding. Dhal et al. reported on thirteen pseudoaneurysms associated with extremity trauma, of these five (38.5%) were caused by external fixation pins. Signs of vascular injury following external fixator pin insertion included bleeding from insertion site, a pulsatile mass, loss of distal pulse, or ischemia. If left untreated, poor peripheral circulation can result to tissue damage, eventually leading to ulcerations, gangrene, and eventually, amputation. It could also lead to healing complications (delayed union, non-union or malunion) (Hernandez et al, 2012). Hence, managing this problem is of utmost priority. Another priority problem in this situation is pain. The data that support there is pain are the pain score of 7/10, elevated heart rate and respiratory rate as well as the fact that the patient underwent an open reduction external fixation for his fractures. Pain is a concern because it aggravates the patient’s diabetes (BGL of 17 mmol/ltr). Having post-operative pain is really stressful and in situations like…

    What forces maintain variation within populations? 3. Do similar forces promote divergence among populations? 4. Why do sex chromosomes have peculiar passing down traits? Research in Dr. McDaniel’s lab aims to answer these questions by using classical genetic and genome analyses of the moss model system, Ceratodon purpureus. They also use Physcomitrella patens, a spreading earth moss, as a model for gene function analysis. These questions pose to look at what the genetic basis of dissociation…

    Three 3X3” plant pots labelled as A, B, and C were used during our experiment. Each pot contained standard soil media with basic nutrients, and 3 Arabidopsis seeds. All pots were watered with appropriate Hoagland’s Solution formulation three times per week over the next 4 weeks. Pot A (phosphate limitation group) was given a phosphate reduced Hoagland’s solution, whereas Pot B (nitrogen limitation group) was watered with nitrate reduced Hoagland’s solution. Pot C (control) is the control plant…

    After amplifying the specific genes from microbial DNA at different sites, we found that nosz was more present in soils under aerobic conditions than under anaerobic conditions. This could be due to the fact that there is less nitrogen in water than in soil. Introduction: Nitrogen cycling allows for living organisms to survive in ecosystems. The nitrogen cycle consists of N₂ from the atmosphere being changed and converted to NO₃ for organisms to properly and then back to N₂. This process of…

    The IT band and gluteus muscle were split in line with the wound. The trochanter bursa was excised, and the fat was retracted over the short external rotator musculature. The piriformis and obturator internus and short external rotators were then dissected free from the posterior greater trochanter and tagged for later reattachment, exposing the posterior hip capsule. The posterior hip capsule was then incised along the intertrochanteric ridge and tagged in a U-type shape for later repair.…
