Objective: This study evaluated the hydrophobicity of dentin surfaces that were modified through chemical silanization with octadecyltrichlorosilane (OTS).
Material And Methods: An in vitro experimental study was performed using 40 human permanent incisors that were divided into the following two groups: non-silanized and silanized. The specimens were pretreated and chemically modified with OTS. After the chemical modification, the dentin hydrophobicity was examined using a water contact angle measurement (WCA). The effectiveness of the modification of hydrophobicity was verified by the fluid permeability test (FPT).
Results And Conclusions: Statistically significant differences were found in the values of WCA and FPT between the two groups. After silanization, the hydrophobic intraradicular dentin surface exhibited in vitro properties that limit fluid penetration into the sealed root canal. This chemical treatment is a new approach for improving the sealing of the root canal system.

Nowadays, direct oral anticoagulants (DOACs) represent the gold standard for venous thromboembolism (VTE) treatment and VTE secondary prophylaxis; nevertheless, the percentage of elderly patients in major trials and literature data about DOACs usage for VTE secondary prophylaxis in the elderly are scant. Our retrospective study tried to evaluate low-dose DOACs efficacy and safety for elderly VTE secondary prophylaxis in a real-life setting. A cohort of 73 patients (≥ 75 years) considered at high risk of VTE recurrence was treated with apixaban 2.

Introduction: During hemodialysis (HD), the presence of clots in the dialyzer can diminish the effective surface area of the device. In severe cases, clot formation in the circuit can halt treatment and lead to blood loss in the system. Thus, ensuring proper anticoagulation during HD is crucial to prevent clotting in the circuit while safeguarding the patient from bleeding risks.

Drug efficacy often correlates better with dissociation kinetics than binding affinity alone. To study binding kinetics computationally, it is necessary to identify all of the possible ligand dissociation pathways. The site identification by ligand competitive saturation (SILCS) method involves the precomputation of a set of maps (FragMaps), which describe the free energy landscapes of typical chemical functionalities in and around a target protein or RNA.

Unlabelled: Purpose: Chemotherapy-induced peripheral neuropathy (CIPN) with associated weakness, areflexia, neuropathic pain, and sensory loss, is a common occurrence in children treated for cancer. However, accurate, quantifiable descriptions of gait deviations due to CIPN are lacking. This scoping review explores common gait abnormalities in children with CIPN.
