Entorhinal Astrocyte Transplants Restore Spatial Exploration and Alleviate Amyloid‐Beta Pathology in Alzheimer's Mice

open access: yesAdvanced Science, EarlyView.
Impaired MEC astrocytic Ca2+ signaling is associated with fragmented spatial exploration in AD mice. Region‐specific glial progenitor transplantation generates engrafted astrocytes that are accompanied by improved AQP4 polarization, reduced amyloid‐β‐associated pathology, attenuated neuroinflammation, preserved synaptic integrity, and ameliorated ...

Early Spatial and Contextual Coding Deficits in Hippocampal CA1 Precede Performance Decline in an Alzheimer's Disease Model

open access: yesAdvanced Science, EarlyView.
Two‐photon calcium imaging in behaving 5xFAD mice reveals early CA1 coding deficits before behavioral decline. Task‐related place cell activity and splitter cell trajectory coding are impaired, with reduced retrospective dominance and greater prospective weighting.

Cuffed Inner Cannula and Flexible Outer Cannula Trachesotomy Device: Ensuring a Stable Airway

open access: yes, 2010
Tracheostomy tubes (TTs) are used to provide a direct airway to a patient’s trachea when natural respiration is no longer possible. A TT generally includes an elongate outer cannula as well as a smaller inner cannula formed so as to have a gradual curve ...

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

open access: yesAdvanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...

Thrombus Formation on Cannulae [PDF]

open access: yesAnaesthesia and Intensive Care, 1980
Seven types of cannulae were inserted into the cephalic vein of sheep which were killed after 1, 3 or 9 days so that the mass of thrombus associated with each cannula could be measured. Statistical analysis indicated that there was a statistically significant difference of greater than 2-fold between types of cannulae in the amount of thrombus ...

CFD study on aortic cannula (flow characteristics) [PDF]

open access: yes, 2015
During cardio-pulmonary bypass (CPB) machine operation, aortic cannula is placed in the right side of the heart. One of the complications in current aortic cannula usage is the sandblasting effect of cannula jet.

A Compact Hollow Fiber Electrode Assembly Architecture for Continuous Electrochemical Marine Carbon Dioxide Removal

open access: yesAdvanced Energy Materials, EarlyView.
A coaxial, membrane‐integrated hollow fiber electrode assembly (HFEA) is developed for continuous marine carbon mineralization. By utilizing a sub‐millimeter inter‐electrode gap, the HFEA minimizes Ohmic losses, achieving 50% energy reduction and over 85% DIC removal.

Innovative reproductive management in rabbits: GnRH-free insemination with specifically designed cannulas for nulliparous and multiparous does

open access: yesFrontiers in Animal Science
Artificial insemination represents a fundamental tool in contemporary rabbit production but continues to depend largely on the administration of exogenous GnRH analogues to trigger ovulation, raising concerns related to animal welfare and long-term ...

Stacked base and cannula system.

open access: yes, 2014
(A) The stacked base is printed as two parts. The lower base (electrode grid) attaches to the recording chamber and allows positioning of the cannula. The grid holes are 500 m in diameter to accommodate 26G cannuli. The upper base (adapter grid) recieves
