Rotation advancement flaps are a challenge for dermatosurgery and in particular the severe clinical cases, mainly affecting skin tumors in the facial area or the so-called ˝high risk areas˝. The proximity of these areas to important vital structures (such as nerves and blood vessels) also determines the need for more precision when performing this type of manipulation. Teamwork and preoperative planning are crucial and provide a number of advantages in terms of the timely achievement of the therapeutic endpoints. We present two cases of patients with squamous cell carcinomas in the periocular and periorbital areas treated by rotation advancement flaps. The problems that may arise within these interventions and the prerequisites for the latter to be successful are discussed.

Background: Total hip arthroplasty is the preferred treatment for advanced hip osteoarthritis, yet complications like hip dislocation (0.2 %-10 %) persist due to factors such as implant design, positioning, surgical technique, and patient-specific conditions. Impingement between prosthetic components or the acetabulum and proximal femur is a primary cause of instability.

Objectives: To investigate maxillary canine movement accuracy and anchorage during space closure in first premolar extraction cases (maximum anchorage) using In-House Clear Aligners (IHCAs).
Materials And Methods: A randomised controlled trial with a split-mouth design recruited 16 adults in university setting. Each patient was randomly assigned by side for canine retraction using 12 IHCAs to both the experimental palatal power arm (Pa) and non-Pa control (C).

Shoulder and elbow injuries are prevalent among baseball players, particularly pitchers, who experience repetitive eccentric loading of the shoulder, leading to muscle damage and increased injury risk. Nearly 40% of shoulder injuries in baseball occur in pitchers, with many facing low rates of return to sport. The rotator cuff (RC) muscles-supraspinatus (SSP), infraspinatus (ISP), subscapularis (SSC), and teres minor (TMin)-are crucial for shoulder stability, movement, and force generation, particularly in overhead sports.

An accurate assessment of the electrodeposition mechanism is essential for evaluating the electrochemical stability and reversibility of the metal anodes. Multiple strategies aimed at uniform Zn deposition have been extensively reported, yet it is challenging to clarify the Zn crystal growth regularity and activity due to the obscured physicochemical properties of as-deposited Zn. Herein, we present a protocol for elucidating the controlled epitaxial growth process of Zn crystals and quantifying their surface electrochemical activity using scanning electrochemical microscopy.

Lysosomes are acidic membrane-bound organelles that aid digestion, excretion, and cell renewal. The lysosomal membranes are essential for maintaining lysosomal functions and cellular homeostasis. In this work, we developed a molecular "NOR" logic gate, , by introducing malachite green into the spirocyclic rhodamine.
