The Journal of Contemporary Dental Practice; Remya M, Singh P et. al.

Oct 20th, 2022 - To compare the centering ability of rotating (ProTaper and Mtwo) and reciprocating (WaveOne and Reciproc) file systems using cone-beam computed tomography (CBCT). Eighty extracted human mandibular molars with curvature within 15-45° were selected and randomly divided into four groups (n = 20): group I (ProTaper), group II (Mtwo), group III (WaveOne), and group IV (Reciproc). The selected teeth ...

Appropriate tube temperature for fiberoptic bronchoscope-guided intubation of thermally...
Medicine Yu Y, Jia Q et. al.

Oct 13th, 2022 - To compare the effects of thermal softening of double-lumen endotracheal tubes (DLT) at different temperatures during fiberoptic bronchoscopy (FOB)-guided intubation. We randomly divided 144 patients undergoing thoracic surgery into 4 groups as follows: T1 (T = 24 ± 1°C, n = 36), T2 (T = 36 ± 1°C, n = 36), T3 (T = 40 ± 1°C, n = 36), and T4 (T = 48 ± 1°C, n = 36). All groups underwent FOB-guided...

Multi-environment robotic transitions through adaptive morphogenesis.
Nature Baines R, Patiballa SK et. al.

Oct 13th, 2022 - The current proliferation of mobile robots spans ecological monitoring, warehouse management and extreme environment exploration, to an individual consumer's home1-4. This expanding frontier of applications requires robots to transit multiple environments, a substantial challenge that traditional robot design strategies have not effectively addressed5,6. For example, biomimetic design-copying a...

Building Australia's first mass spectrometer: Recognising the achievements of J. Roger ...
Journal of Mass Spectrometry : JMS; Downard KM

Oct 12th, 2022 - Following the birth of the field of mass spectrometry at the end of World War I, it was several decades before the first commercial mass spectrometers became available. In the interim, many physicists interested in the nature of matter, and their application to studies in nuclear physics, constructed their own. A young physics postgraduate student, John Roger Bird, was the first to do so in Aus...

Multicenter, Randomized Trial of a Bionic Pancreas in Type 1 Diabetes.
The New England Journal of Medicine; , Russell SJ et. al.

Sep 29th, 2022 - Currently available semiautomated insulin-delivery systems require individualized insulin regimens for the initialization of therapy and meal doses based on carbohydrate counting for routine operation. In contrast, the bionic pancreas is initialized only on the basis of body weight, makes all dose decisions and delivers insulin autonomously, and uses meal announcements without carbohydrate coun...

Continuous air purification by aqueous interface filtration and absorption.
Nature Zhang Y, Han Y et. al.

Sep 27th, 2022 - The adverse impact of particulate air pollution on human health1,2 has prompted the development of purification systems that filter particulates out of air3-5. To maintain performance, the filter units must inevitably be replaced at some point, which requires maintenance, involves costs and generates solid waste6,7. Here we show that an ion-doped conjugated polymer-coated matrix infiltrated wit...

Cell Rover-a miniaturized magnetostrictive antenna for wireless operation inside living...
Nature Communications; Joy B, Cai Y et. al.

Sep 23rd, 2022 - An intracellular antenna can open up new horizons for fundamental and applied biology. Here, we introduce the Cell Rover, a magnetostrictive antenna which can operate wirelessly inside a living cell and is compatible with 3D biological systems. It is sub-mm in size, acoustically actuated by an AC magnetic field and resonantly operated at low MHz frequencies, which is ideal for living systems. W...

Transition metal dichalcogenide nanospheres for high-refractive-index nanophotonics and...
Proceedings of the National Academy of Sciences of the Un... Tselikov GI, Ermolaev GA et. al.

Sep 20th, 2022 - Recent developments in the area of resonant dielectric nanostructures have created attractive opportunities for concentrating and manipulating light at the nanoscale and the establishment of the new exciting field of all-dielectric nanophotonics. Transition metal dichalcogenides (TMDCs) with nanopatterned surfaces are especially promising for these tasks. Still, the fabrication of these structu...

A Flexible Chamber for Time-Lapse Live-Cell Imaging with Stimulated Raman Scattering Mi...
Journal of Visualized Experiments : JoVE; Yuan Y, Lu F

Sep 20th, 2022 - Stimulated Raman scattering (SRS) microscopy is a label-free chemical imaging technology. Live-cell imaging with SRS has been demonstrated for many biological and biomedical applications. However, long-term time-lapse SRS imaging of live cells has not been widely adopted. SRS microscopy often uses a high numerical aperture (NA) water-immersion objective and a high NA oil-immersion condenser to ...

Cerebral Embolic Protection during Transcatheter Aortic-Valve Replacement.
The New England Journal of Medicine; Kapadia SR, Makkar R et. al.

Sep 20th, 2022 - Transcatheter aortic-valve replacement (TAVR) for the treatment of aortic stenosis can lead to embolization of debris. Capture of debris by devices that provide cerebral embolic protection (CEP) may reduce the risk of stroke. We randomly assigned patients with aortic stenosis in a 1:1 ratio to undergo transfemoral TAVR with CEP (CEP group) or without CEP (control group). The primary end point w...

Topographic design in wearable MXene sensors with in-sensor machine learning for full-b...
Nature Communications; Yang H, Li J et. al.

Sep 10th, 2022 - Wearable strain sensors that detect joint/muscle strain changes become prevalent at human-machine interfaces for full-body motion monitoring. However, most wearable devices cannot offer customizable opportunities to match the sensor characteristics with specific deformation ranges of joints/muscles, resulting in suboptimal performance. Adequate wearable strain sensor design is highly required t...

Slowly absorbable mesh versus standard care in the management of contaminated midline i...
BMJ Open; Passot G, Margier J et. al.

Aug 26th, 2022 - Incisional hernia (IH) is the most frequent mid-term and long-term complication after midline laparotomy. The current standard treatment includes repair using a mesh. In a contaminated field, the use of a non-absorbable mesh increases the risk of surgical site infection and the costs. Slowly absorbable meshes are safe in contaminated fields, but no data have been reported regarding their long-t...

Comparison of two sizes of GlideScope® blades in tracheal intubation of infants: a rand...
British Journal of Anaesthesia; Kwon JH, Chung YJ et. al.

Aug 24th, 2022 - The appropriate size of GlideScope® blade for tracheal intubation in neonates and premature infants has not been established. We evaluated the impact of the size of the GlideScope® blade on the time taken for intubation in infants weighing 2.5-3.6 kg. Sixty infants weighing 2.5-3.6 kg were randomly assigned to use of the size 1 blade (n=30) or the size 2 blade (n=30). The primary outcome was th...
