The Novel Dual GIP and GLP‐1 Receptor Agonist Tirzepatide Attenuates Colon Cancer Development by Regulating Glucose Metabolism

Advanced Science, EarlyView.
Tirzepatide, a dual GIP/GLP‐1 receptor agonist for diabetes, suppresses colorectal cancer growth by targeting glucose metabolism. It inhibits cancer cell proliferation, promotes apoptosis, and induces tumor regression. It reduces glucose uptake and destabilizes HIF‐1α for degradation to downregulate PFKFB3/PFK‐1 enzymes, thus contributing to the ...

Electrostatically Reinforced Double Network Granular Hydrogels

Advanced Science, EarlyView.
Electrostatically reinforced double network granular hydrogels (DNGHs) with cartilage‐like fracture energy are introduced. An empirical model predicts the composition‐dependent fracture energy based on dissipation zone size, contact area, and inter‐particle adhesion energy. Thanks to their granular structure and the inter‐particle attraction, the DNGHs

Measuring muscle strength

Journal of Neurology, 1984
A dynamometer that can be held in the hand and that was designed to measure muscle strength in a simple way in the range 2-5 of the MRC scale, was tested in order to establish to what extent differences in results can be attributed to the observer, the subject and replication.

Association between tongue muscle strength and masticatory muscle strength

Journal of Oral Rehabilitation, 2018
SummaryBackgroundThe tongue is responsible for compressing food against the palate and squeezing it into the pharynx during the oral preparatory phase of swallowing. Tongue pressure (TP), an indicator of tongue muscle strength, has been observed to decline with age; maximum occlusal force (MOF), an indicator of chewing ability, is correlated with TP ...

Calf Muscle Strength in Humans

International Journal of Sports Medicine, 1995
In an effort to measure strength characteristics of the calf muscles, 18 subjects (14 male, 4 female, age =34.3+/-2.4yrs) were tested using a specially designed torque velocity device (TVD). This TVD is a hardware interface with the subject's lower leg which stabilizes the leg for calf muscle strength measurements.

Human jaw muscle strength and size in relation to limb muscle strength and size

European Journal of Oral Sciences, 2004
The aim of the present study was to investigate to what extent general factors (e.g. genotype, hormones) and factors at the craniofacial level (e.g. craniofacial size, jaw muscle architecture) contribute to the size and strength of the jaw muscles. A strong relationship of jaw muscle size and strength with that of other muscles would argue for general ...
