Membrane potential sensing: Material design and method development for single particle optical electrophysiology.

We review the development of "single" nanoparticle-based inorganic and organic voltage sensors, which can eventually become a viable tool for "non-genetic optogenetics." The voltage sensing is accomplished with optical imaging at the fast temporal response and high spatial resolutions in a large field of view. Inorganic voltage nanosensors utilize the Quantum Confined Stark Effect (QCSE) to sense local electric fields.

Optical probing of local membrane potential with fluorescent polystyrene beads.

The study of electrical activity in single cells and local circuits of excitable cells, such as neurons, requires an easy-to-use, high-throughput methodology that allows for the measurement of membrane potential. Investigating the electrical properties in specific subcompartments of neurons, or in a specific type of neurons, introduces additional complexity. An optical voltage-imaging technique that allows high spatial and temporal resolution could be an ideal solution.

A virtual reality system for pain and anxiety management during outpatient hysteroscopy-A randomized control trial.

Background: Visual and acoustic virtual reality (VR) has been increasingly explored as a non-pharmacological tool for pain relief in clinical settings.

Objective: We aimed to evaluate the effectiveness of VR as a distraction technique in the management of acute pain during operative hysteroscopy in the outpatient setting.

Methods: A prospective, open-label, randomized control trial in a tertiary university-affiliated medical centre between April and August 2020.

Point-localized, site-specific membrane potential optical recording by single fluorescent nanodiscs.

Nanodisc technology was implemented as a platform for voltage nanosensors. A fluorescence (Förster) resonance energy transfer (FRET)- based voltage-sensing scheme employing fluorescent nanodiscs and the hydrophobic ion dipicrylamine was developed and utilized to optically record membrane potentials on the single-nanodisc level. Ensemble and single-nanosensor recordings were demonstrated for HEK293 cells and primary cortical neuron cells.

Weak Electromagnetic Fields Accelerate Fusion of Myoblasts.

Weak electromagnetic fields (WEF) alter Ca handling in skeletal muscle myotubes. Owing to the involvement of Ca in muscle development, we investigated whether WEF affects fusion of myoblasts in culture. Rat primary myoblast cultures were exposed to WEF (1.

Angiography in patients with pelvic fractures and contrast extravasation on CT following high-energy trauma.

Introduction: Pelvic fracture may be accompanied by severe bleeding. Computed tomography (CT) is a gold standard diagnostic tool in stable trauma patients. Contrast extravasation detected on CT of pelvis is a sign of hemorrhage, but its significance is not clear.

Interfacing the Cell with "Biomimetic Membrane Proteins".

Integral membrane proteins mediate a myriad of cellular processes and are the target of many therapeutic drugs. Enhancement and extension of the functional scope of membrane proteins can be realized by membrane incorporation of engineered nanoparticles designed for specific diagnostic and therapeutic applications. In contrast to hydrophobic insertion of small amphiphilic molecules, delivery and membrane incorporation of particles on the nanometric scale poses a crucial barrier for technological development.

Frequency of intra-abdominal organ injury is higher in patients with concomitant stab wounds to other anatomical areas.

Background: Management of stable patients with abdominal stab wound remains controversial, particularly for those with no clear indications for explorative laparotomy. We evaluated the risk of intra-abdominal injury in stab wound victims concomitantly stabbed in other anatomical body areas.

Methods: We performed a retrospective cohort study of patients with abdominal stab wounds recorded in the Israeli National Trauma Registry from January 1st, 1997, to December 31st, 2013.

When Should Abdominal Computed Tomography Be Considered in Patients with Lower Rib Fractures?

Background: Lower rib fractures are considered as a marker of intra-abdominal organ injury. Abdominal computed tomography (CT) is the "gold standard" examination for patients with lower rib fractures. However, the reported incidence of concomitant intra-abdominal injuries (IAI) is 20%-40%.

D1 versus D2 Gastrectomy for Gastric Adenocarcinoma.

Background: Despite the ongoing decrease in the incidence of gastric cancer, this disease is still a major cause of death. It is still debatable whether D2 lymphadenectomy improves survival and whether this procedure should be performed routinely or selectively.

Objectives: To compare the pathological and short-term results following radical D2-type gastric resection and lymphadenectomy versus the more limited D1 type resection and lymphadenectomy.

Elevated white blood cell count, decreased hematocrit and presence of macrohematuria correlate with abdominal organ injury in pediatric blunt trauma patients: a retrospective study.

Introduction: Computerized tomography (CT) has become an important diagnostic modality in trauma patients. Pediatric patients are particularly susceptible to ionized radiation making liberal CT use in this age group unacceptable. We aimed to identify parameters that might predict abnormal findings on abdominal CT leading to patient management changes.

Diagnostic Use of Endoscopic Retrograde Cholangiopancreatectography for Pancreatic Duct Injury in Trauma Patients.

Background: Trauma patients diagnosed with pancreatic duct injury (PDI) have a high complication rate and prolonged hospital stay. The role of endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of PDI remains unclear. During the last decade, our trauma unit incorporated ERCP into the management protocol for suspected PDI cases.
