NEBS and PIEZO2: Guardians of the Respiratory Galaxy
In a recent Nature publication by Schappe,M (2024), researchers have revealed a fascinating aspect of respiratory physiology: the role of sensory neurons in guarding against airway obstruction and orchestrating crucial reflexes to maintain respiratory function. The study explores the intricate neural pathways involved in detecting and responding to airway closure. By characterizing a ...

Scireq Softrestraint for Exposure Studies
Evaluating the stress related effects of various restraint methods in rodents Any restraining device used in an inhalation exposure set-up will be, by definition, restricting the subject’s ability to move. For nose-only inhalation set-ups, typical restraints are rigid, fully enclosed and include a metal or acrylic plunger forcing the subject forward and preventing the subject from ...

The Functions and Roles of Enzymes
Catalysis Enzymes are a class of biological catalysts. They govern many catalytic processes such as metabolism, nutrition, and energy conversion of organisms. Most of the reactions closely related to life processes are enzyme-catalyzed reactions. These properties of the enzyme enable the intricate process of material metabolism in the cell to proceed in an orderly manner, and to adapt material ...

Shoulder Subluxations (aka Slipped Shoulders) After Stroke
Introduction: What Is A Subluxation? Following the onset of a stroke, it is common that the hemiparetic arm may experience something called a subluxation or “slipped shoulder”. This is a very common impairment that follows in the wake of arm weakness caused by a stroke. Shoulder subluxations occur in the glenohumeral joint of the shoulder. This is the area in which the humerus (bone ...

Importance of hemodynamic monitoring during esophagectomy - Case Study
Background Esophagectomy for cancer involves two- or three-phase procedures, such as abdominal, chest and/or neck incisions, is more invasive than other types of gastrointestinal surgery, and is associated with high risk for postoperative morbidity. Because of this risk, perioperative management of circulatory conditions such as hypovolemic hypotension is especially important to avoid ...

Point of care pulmonary function testing: Important now, more than ever
As the relentless waves of the COVID-19 pandemic continue to wash over the world, much attention has been focused on the idea of hospital bed shortages. As cases strain hospital systems everywhere, the most-commonly reported metrics one hears have to do with beds; how many ICU beds left, how many emergency beds, how many beds overall. While it is of course critical to understand how much physical ...

Robotic Surgery: Who will be the Next Top Dog?
The competitive stakes in robotic surgery have never been higher as medical device companies try to disrupt the market that Intuitive Surgical pioneered more than two decades ago. Robotic surgery pioneer Intuitive Surgical celebrated a big milestone this week: The number of robotic-assisted procedures performed worldwide using the da Vinci surgical system has just surpassed 10 million. ...

Best Material To Practice Your Suturing Skills
You've probably heard amazing stories of surgeons performing successful, yet extremely delicate and risky procedures such as open-heart surgery, separation of conjoined twins, craniotomy, thoracic aortic dissection repair, oesophagectom, spinal osteomyelitis surgery, and many more. As a medical student, you wonder how a surgeon can do such an incredible job. Well, the answer lies in lots of ...

Advantages of using Spine 3D(CT-based) Navigation in complex Spine Surgeries
To confidently perform a spinal fusion and screw fixation with excellence surgical navigation is consistently used as a powerful tool. Surgical Navigation provides real-time guidance and precise measurements for accurately placing the pedicle screws to help stabilize the spine. A preoperative CT scan gives a detailed visualization of the structure decreasing the potential for implant-related ...

A robot at the operating table - Case Study
The robot arms move above the patient’s stomach as if guided by an invisible hand. Monitors on each side of the operating table show an oversized, 3-D image of the stomach’s interior. Two meters (about six feet) away, Dr. Markus Mille sits fully absorbed at the control ...

What Is the Difference Between Respiratory Allergy and Asthma?
Nothing is more frightening than when you cannot catch your breath. Your chest tightens, and you just cannot pull in enough oxygen. At first glance, both an allergy and asthma will look the same. Doctors even treat them similarly. To learn the difference between a respiratory allergy and asthma today, keep reading! Parts of the Airway To best understand the similarities and differences between ...

A Conversation with Prof. Davide Capodanno, M.D., Ph.D. on the Landmark TAILOR-PCI Clinical Trial Results
After seven years and 5,300-patients tested, the results of the landmark TAILOR-PCI trial were announced in a virtual ACC session. This trial investigated whether a prospective approach using rapid on-site CYP2C19 testing could improve patient outcomes when selecting P2Y12 inhibitor therapy following PCI procedure. This is based on the well-established evidence that approximately 30-50% of ...

Results support feasibility of entirely extracardiac, minimally invasive, temporary pacing system
New results support the feasibility of an entirely extracardiac pacing method in a heterogeneous patient population, using a minimally invasive, parasternal delivery approach, with adequate sensing and thresholds suited for temporary pacing. The study, authored by Anne-Floor BE Quast, Niek EG Beurskens (University of Amsterdam, The Netherlands) and colleagues, was recently published in ...

Application of refractable nanocomposite on cell based therapy in central nervous system
Quantum Dots (QDs) are nano–particles carrying high stability fluorescence to follow the grafted cells which can be used in investigating the movement of cells and understanding the organogenesis of stem cells during development and wound repair processes in adulthood. For its easy acquirement and bypassing moral ethical issues, it makes the human adipose derived stem cells an attractive, ...

Medical Surveillance of Search Dogs Deployed to the World Trade Center and Pentagon: 2001–2006
In response to the terrorist attacks of September 11, 2001, at the World Trade Center and Pentagon, almost 50,000 rescue workers and approximately 300 search and rescue dogs participated in rescue and recovery operations. The dogs were exposed to the same hazards as the human workers, but did not have any of the personal protective gear. This prospective double cohort observational study compared ...

Assessment of absorbed dose in digital and MIRD phantoms by MCNP in thorax area
This paper describes the development of mathematical models, called phantoms, for the assessment of absorbed doses caused by internal radionuclides. In more developed phantoms, anatomical models based upon 3D imaging methods are used. Cross-sectional anatomical models consist of numerous arrays of voxels, each of which individually corresponds to an organ. The digital phantom presented in this ...

Dose and risk evaluation in thoracic radiology using male and female voxel phantoms
Thoracic radiology is of great concern because of its routine nature. It is important to avoid conditions where the amount of radiation used is more than that needed for the procedure. The purpose of this work is to use the Monte Carlo code MCNPX and the Female Adult voxel (FAX) and Male Adult voxel (MAX) phantoms to investigate how the effective doses, absorbed doses to organs and risk of cancer ...

AP and PA thorax radiographs: dose evaluation using the FAX phantom
Considering that the risks associated with ionising radiation are dependent on the characteristics of the exposed individual and that the structures and sizes of the human body vary considerably as a function of gender, efforts must be made in order to study the effective and absorbed doses in thoracic radiological examinations, taking into account the special features of the female anatomy. In ...
