Complement fixation test
For more information, log on to- http://shomusbiology.weebly.com/ Download the study materials here- http://shomusbiology.weebly.com/bio-materials.html Source of all articles published in description is Wikipedia. Thanks to original content developers. Link- http://en.wikipedia.org/wiki/Main_Page The complement fixation test is an immunological medical test that can be used to detect the presence of either specific antibody or specific antigen in a patient's serum. It was widely used to diagnose infections, particularly with microbes that are not easily detected by culture methods, and in rheumatic diseases. However, in clinical diagnostics labs it has been largely superseded by other serological methods such as ELISA and by DNA-based methods of pathogen detection, particularly PCR. The complement system is a system of serum proteins that react with antigen-antibody complexes. If this reaction occurs on a cell surface, it will result in the formation of trans-membrane pores and therefore destruction of the cell. The basic steps of a complement fixation test are as follows:[1] Serum is isolated from the patient. Patients naturally have different levels of complement proteins in their serum. To negate any effects this might have on the test, the complement proteins in the patient's serum must be destroyed and replaced by a known amount of standardized complement proteins. The serum is heated in such a way that all of the complement proteins—but none of the antibodies—within it are destroyed. (This is possible because complement proteins are much more susceptible to destruction by heat than antibodies.) A known amount of standard complement proteins are added to the serum. (These proteins are frequently obtained from guinea pig serum.) The antigen of interest is added to the serum. Sheep red blood cells (sRBCs) [2] which have been pre-bound to anti-sRBC antibodies are added to the serum. The test is considered negative if the solution turns pink at this point and positive otherwise. If the patient's serum contains antibodies against the antigen of interest, they will bind to the antigen in step 3 to form antigen-antibody complexes. The complement proteins will react with these complexes and be depleted. Thus when the sRBC-antibody complexes are added in step 4, there will be no complement left in the serum. However, if no antibodies against the antigen of interest are present, the complement will not be depleted and it will react with the sRBC-antibody complexes added in step 4, lysing the sRBCs and spilling their contents into the solution, thereby turning the solution pink.

Here, the core provides inner surface and the inner diameter, while the outer border of thread provides the outer diameter of the crew. The distance in between the two threads is called the 'pitch' [Figure 2]. In cortical screws, the pitch is smaller, and in cancellous screws, the pitch is wider. This area between the threads is vital in providing bone purchase, and hence, is an important deciding factor in determining the 'pull-out strength' of the screw. The pull-out strength is assessed by a constant axial force applied to dislodge the screw from a vertebra where it was secured earlier in a laboratory condition. The force utilized to dislodge the screw is called the 'pull-out force'. A good pedicle screw should have a good pull-out strength particularly in an osteoporotic bone. Deeper threads, a larger pitch, and longer screws with a bicortical purchase can improve the pull-out strength of a screw. However, these types of screws are not without limitations when being placed in an osteoporotic vertebral body where a breach of bone may occur during the insertion of the screw. In the dorsal and lumbar regions of the spine, a bicortical purchase of the vertebra is fraught with danger as there is the risk of injuring the ventrally placed large vessels. The length of the screw that is inserted within the body is not very important since the cancellous part of the vertebral body contributes less than 20% in improving the pull-out strength. The pedicle contributes around 60% of the pull-out strength, and in combination with the cortical bone that comprises of the proximal part of the vertebral body near the pedicle, contributes much more to the pull-out strength. Hence, the only way one can improve the pull-out strength, and in turn, achieve a strong fixation is to achieve a bicortical purchase; however, the limitation in achieving a bicortical purchase has already been discussed. Figure 1: The standard screw has a cylindrical core and a cylindrical thread Figure 2: The core provides inner surface and the inner diameter, while the outer border of thread provides the outer diameter of the crew. The distance in between the two threads is called the 'pitch' Conical screws have a conical core with cylindrical threads, which means that the inner diameter of the screw is progressively larger at the proximal end [Figure 3]. Since the threads are cylindrical all along the screw, the area of bone purchase is larger and there will be constant compression of cancellous bone around the screw distally that improves the pull-out strength. Hence, this design is popular and relied upon. Moreover, the screw insertion in the case of a conical screw is easier compared to the standard one. Attempting further improvement in these screws by adding self-tapping ridges to avoid tapping as a separate step of the pedicle screw insertion procedure did not practically improve the pull-out strength of these screws [Figure 4]. Recently, double threaded conical screws have been introduced that aim to provide appropriate threads at the pedicle (containing the cortical bone) and the body (containing the cancellous bone) [Figure 5]. Inspite of these modifications in the vertebral screw technology, there are still less-than-satisfactory outcomes in the presence of osteoporosis due to the destruction of the bony architecture of the vertebral body. To obviate this and to enhance the screw purchase strength, different varieties of bone cement have been introduced at the distal end of screw through a cannulated screw design. These cannulated conical screws have pores at the distal end between threads through which a fast setting cement can be injected into the osteoporotic cancellous bone which can grip the screw and hold it in place, and hence, can increase the pull-out strength of the screws [Figure 6]. This system is gaining popularity in the recent times and is used both in the open and percutaneous forms of spinal fixation. PMMA (polyme

Synthetic Biology: Realizing synthetic carbon dioxide fixation - Tobias Erb
https://www.ibiology.org/bioengineering/synthetic-carbon-dioxide-fixation/ Tobias Erb outlines the principles of building synthetic metabolism using, as an example, work in his lab to engineer bacteria to undergo synthetic carbon dioxide fixation. Talk Overview: The conversion of atmospheric carbon dioxide (CO2) to biomass via photosynthesis is the foundation for all of our food and energy. Tobias Erb explains how his lab is working to design, build and optimize pathways for synthetic CO2 fixation. By combining enzymes from multiple organisms with “re-engineered” enzymes and optimizing the processes, Erb and his lab generated a synthetic cycle that fixes CO2 more energy efficiently than photosynthesis. In the future, they plan to test the system in artificial cells and to transplant it into bacteria and chloroplasts.  The video exemplifies the general rules and principles of building synthetic metabolism. Speaker Biography: Tobias Erb studied biology and chemistry at the University of Freiburg and Ohio State University. He was a postdoctoral fellow at the University of Illinois before starting his own group at the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland.  In 2014, Erb moved to the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany where he became Director and Head of the Department of Biochemistry and Synthetic Metabolism in 2017. Erb’s lab studies the principles of natural metabolism with the aim of using this knowledge to build, from basics, novel synthetic metabolic processes.  Erb is particularly interested in the enzymes and pathways of bacteria that capture and convert carbon dioxide. In 2015, Erb was named one of 12 up-and-coming-scientists by the American Chemical Society and in 2016 he received the Heinz-Maier-Leibniz prize of the German Research Foundation.   Learn more about Erb’s research here: http://www.mpi-marburg.mpg.de/erb

External Fixation With Locking Plate - Everything You Need To Know - Dr. Nabil Ebraheim
Educational video describing external fixation utilizing a locking plate. Certain orthopedic conditions can be treated with an external fixator. New recent advances in fracture fixation are achieved by utilizing a locking plate as an external fixator. The plate is used outside of the skin. External fixator plate is used when internal fixation is not possible nor preferable. The locking plate can be used temporarily or permanently to achieve healing. This construct is mainly used for stabilization of the tibia and the femur.

Bone Healing, Buttress Plate  - Everything You Need To Know - Dr. Nabil Ebraheim
Dr. Ebraheim’s educational animated video describes bone healing and buttress plating of fractures. Some fractures can shorten and displace under axial load, and these fractures are best stabilized with a buttress plate. Buttress plates are mainly used in the metaphysis area to support an intra-articular fracture. When a buttress plate is used in the diaphyseal area to support a fracture, it is called an anti-glide plate. Apply the plate to one main fragment to buttress the other fragment and to prevent displacement. The plate acts like a finger, pushing the other fragment into the reduced position (buttress means "push) and the plate holds the bone up. The plate neutralizes the shear forces during axial load. In fact, it may compress the fracture during axial loading. If the fracture is antra-articular, the the plate can be used with or without lag screws (usually partially threaded screws are used). Examples of buttress plates: -Volar Barton fracture- anterior plate is applied to the distal radius to hold the reduced anterior marginal distal radius fracture. If the fragment is large enough, screws can be put through it. But, if the fragment is small, a plate can be used without screws. - Tibial plateau fracture: The split fracture used buttress plating. -Vertical fracture of the medial malleolus ( a supination/adduction fracture) -Posterior malleolar ankle fracture. Example of the anti-glide plate -Diaphyseal fracture of the fibula: Some physicians believe it is mechanically superior to the lateral plate, but it can cause irritation of the peroneal tendons. The stiff plate should match the contour of the bone. Most plates used now are pre-contoured or anatomic. A metaphyseal shear fracture, or split fracture, fixation with screws alone may not be sufficient. Lag screws should be combined with a plate with anti-glide or buttress effect. You will get primary bone healing using a buttress plate because of the anatomic reduction, the stable fixation, and adequate blood supply.

Balancing AO Principles in Calcaneus Fractures
The calcaneus, also known as the heel bone, is responsible for transmitting the majority of the body's weight from the talus bone to the ground. Nearly every aspect of the management of complex calcaneus fractures is controversial. The anatomy of the calcaneus is complicated and treatment of fractures in this bone requires a comprehensive understanding of its anatomy, common fracture patterns, and displacement. An accurate reduction is essential to good patient outcomes. Treatment options include closed management, an extensile lateral open approach and the mini-open technique. This presentation highlights the indications for each technique, compares and contrasts their strengths and weaknesses, and provides case examples with discussion from some of the leaders in the field of calcaneus fracture management.
