What is the principle of SDS-PAGE?
The principle of SDS-PAGE states that a charged molecule migrates to the electrode with the opposite sign when placed in an electric field. The separation will take place as the mobility of the charged species. The tiny molecules tend to move faster due to their less resistance at the time of electrophoresis. The rate of migration influences the structure and the charge of the protein.

SDS, SDS Plus, and SDS max are them. All are the same with the mechanism, and some small differences are there. A conventional hammer drill works with bearing and clutch. But The SDS hammer drills work with piston mechanisms.
Why Do We Need SDS Hammer Dril?
Normally SDS hammer drills are needed for heavy-duty works such as concrete drilling with reinforcements. So SDS hammer drills are very important. We are not able to use regular hammer drills for concrete drilling. It does not power with more diameter drill bits as well as when the drilling depth is increased.

What is SPECT in myocardial perfusion?
This article discusses the protocol for myocardial perfusion scintigraphy performed with single-photon emission computed tomography (SPECT). Indications for SPECT are listed with consideration given to the results of the increasingly more common angio-CT examinations of the coronary arteries (multislice computed tomography). The paper also presents basic information about interpreting the results, including the scores of left ventricle myocardial perfusion using the 17-segment polar map, and explains the concept of total perfusion deficit.
What does a post-MI scarring test show?
Depending on the type of myocardial perfusion disturbance, the examination may indicate post-MI scarring (when the resting examination shows reduced radiotracer uptake) or a reversible perfusion deficit (stress ischemia) when the radiotracer’s activity is reduced during the stress examination, but not during the rest examination. In other situations, the examination may reveal post-MI scarring along with surrounding ischemia (resulting, e.g., from insufficient collateral circulation) or the presence of concurrent post-MI scarring (permanent perfusion deficit) in an area supplied by one vessel and ischemia (reversible deficit) in another area.
How often do you need to administer a radiotracer?
In order to obtain the image of cardiac perfusion during stress and rest, the radiotracer must be administered twice: at the peak of stress and during rest.
How many segments are there in the polar map of left ventricular perfusion?
2). It is created as a result of imaging the distribution of radiotracer activity in two dimensions (Fig. 3). The model established by the American Heart Association (AHA) divides the polar map into 17 segments. The outermost segments correspond to the basal segments, and segment 17 represents the cardiac apex (Fig. 4).
Why is 201Tl used at peak stress?
A one-time administration of 201Tl at peak stress enables the performance of a one-day examination that will visualize radiotracer uptake during stress as well as rest because the radiotracer is redistributed after a while. However, the use of 201Tl is not widespread for two main reasons.
What is SPECT CT?
A SPECT-CT device is additionally equipped with a tomograph integrated with the gamma camera. CT enables reconstruction with attenuation correction, facilitating the elimination of false perfusion deficits resulting from the attenuation of emission by extracardiac tissues. This type of examination involves both transmission and emission as it consists in both a tomographic examination (exposition to X-ray radiation) and a second, main tomographic examination, superimposed over the first one, for imaging left ventricular perfusion (emission scintigraphy).
What is SPECT imaging?
Single-photon emission computed tomography (SPECT) is an imaging method that enables, among other things, the evaluation of myocardial perfusion. The source emitting the radiation is the patient, who is administered a radioactive tracer. The name tomography stems from Greek tomos,meaning “section” or “cut”. Isotopic tomographic examination enables the determination of radiotracer accumulation in many sections. After the image is reconstructed, radiotracer activity is evaluated in sections along the short and long axis: the sagittal and frontal section.
