We present an experimental procedure of Candida albicans biofilm development in a mouse subcutaneous model. Fungal biofilms were quantified by determining the number of colony forming units and by a non-invasive bioluminescence imaging, where the amount of light that is produced corresponds with the number of viable cells.

Source: Ricardo Mejia-Alvarez, Hussam Hikmat Jabbar and Mahmoud N. Abdullatif, Department of Mechanical Engineering, Michigan State University, East Lansing, MI Owing to the non-linear nature of its governing laws, fluid motion induces complicated flow patterns. Understanding the nature of these patterns has been the subject of intense scrutiny for centuries. Although personal computers and supercomputers are extensively used to deduce fluid flow patterns, their capabilities are still...

Source: Ketron Mitchell-Wynne, PhD, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA Equilibrium is a special case in mechanics that is very important in everyday life. It occurs when the net force and the net torque on an object or system are both zero. This means that both the linear and angular accelerations are zero. Thus, the object is at rest, or its center of mass is moving at a constant velocity. However, this...

Body Temperature

The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...
FAQs
No single imaging method provides every relevant detail. Plain radiography, ultrasound, and computed tomography detect different materials and contribute different anatomical information, so clinicians select or combine them according to the suspected object and its location. This complementary strategy improves planning by clarifying where the object lies, how deep it is, and which surrounding structures may affect retrieval.
The injury history can suggest how the object entered and where it may be retained, while physical examination supplies clinical findings at the affected site. These sources guide interpretation of imaging rather than replacing it. Correlating the history and examination with radiographic, sonographic, or computed tomographic findings helps clinicians assess whether the identified object matches the suspected injury.
Depth and orientation are not merely descriptive findings; they influence the safest route to the object. When localization shows proximity to nerves, vessels, or other organs, clinicians can plan to avoid those structures and limit unnecessary tissue dissection. Thus, better anatomical definition can change the retrieval approach and reduce the risk of procedure-related injury.
A practical localization workflow begins with the injury history and physical examination, followed by imaging selected for the suspected foreign body and anatomical question. Plain radiography, ultrasound, or computed tomography may be used alone or as complementary studies. The resulting position, depth, and orientation guide treatment planning before removal and provide a basis for checking the result afterward.
When a retained object lies near soft-tissue structures, real-time ultrasound can provide localization during the assessment or intervention. Its live imaging helps clinicians relate the object to nearby anatomy as they plan or perform the procedure. This capability is particularly useful when static anatomical information is insufficient for guiding a careful approach.
Foreign body localization supports decisions in emergency, surgical, and procedural medicine. In each setting, the information is useful not only before retrieval but also afterward, when clinicians need to confirm that the object has been removed. This makes localization part of the full management pathway, linking initial assessment, selection of a retrieval strategy, and post-removal verification.
