Fretting-corrosion at the Implant-Abutment Interface Simulating Clinically Relevant Conditions.

Objective: Implant treatment is provided to individuals with normal, idealized masticatory forces and also to patients with parafunctional habits such as grinding, clenching, and bruxing. Dental erosion is a common increasing condition and is reported to affect 32 % of adults, increasing with age. This oral environment is conducive to tribocorrosion and the potential loss of materials from the implant surfaces and interfaces with prosthetic components.

Loss of anoctamin 1 reveals a subtle role for BK channels in lymphatic muscle action potentials.

Ca signalling plays a crucial role in determining lymphatic muscle cell excitability and contractility through its interaction with the Ca-activated Cl channel anoctamin 1 (ANO1). In contrast, the large-conductance (BK) Ca-activated K channel (KCa) and other KCa channels have prominent vasodilatory actions by hyperpolarizing vascular smooth muscle cells. Here, we assessed the expression and contribution of the KCa family to mouse and rat lymphatic collecting vessel contractile function.

Size Constancy Mechanisms: Empirical Evidence from Touch.

Several studies have shown the presence of large anisotropies for tactile distance perception across several parts of the body. The tactile distance between two touches on the dorsum of the hand is perceived as larger when they are oriented mediolaterally (across the hand) than proximodistally (along the hand). This effect can be partially explained by the characteristics of primary somatosensory cortex representations.

C-H⋯O contacts in the crystal structure of 1,3-di-thiane 1,1,3,3-tetra-oxide.

The crystal structure of 1,3-di-thiane 1,1,3,3-tetra-oxide, CHOS, has been determined to examine the inter-molecular C-H⋯O hydrogen bonds in a small mol-ecule with highly polarized hydrogen atoms. The crystals are monoclinic, space group n, with = 4.9472 (5), = 9.

Maintaining medical team communication using video conferencing during the COVID-19 lockdown.

COVID-19 is a global pandemic of unprecedented proportions. It has resulted in changes to all aspects of our lives. The impact on medicine has been significant.
