Preparation of protein-functionalized planar glass-supported lipid bilayers, determination of protein mobility within and measurement of protein densities is shown here. A roadmap to building a noise-reduced Total Internal Reflection microscope is outlined, which allows visualizing single bilayer-resident fluorochromes with high spatiotemporal resolution.

2025
Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems. Accessibility and Cost-Effectiveness One of the primary strengths of self-help...

Sample preparation for cryo-electron microscopy (cryo-EM) is a significant bottleneck in the structure determination workflow of this method. Here, we provide detailed methods for using an easy-to-use, three-dimensionally printed block for the preparation of support films to stabilize samples for transmission EM studies.
FAQs
During this phase, coordinated control at the stance limb’s hip, knee, and ankle stabilizes the pelvis while the body’s center of mass moves over the supporting foot. This joint-level coordination allows the weight-bearing limb to remain controlled as the opposite limb advances, supporting both balance and forward progression through the gait cycle.
The body’s center of mass must progress over the supporting foot while the opposite lower extremity advances. Coordinating this movement helps maintain balance without interrupting forward progression. Clinically, difficulty controlling the center of mass can indicate impaired balance or weakness and may explain abnormalities observed during gait analysis.
Weakness in the lower extremity that supports body weight can reduce the stability of the pelvis and stance limb. Because the hip, knee, and ankle must work together during single limb support, impairment in one area may disrupt balance or forward progression. Gait assessment helps clinicians identify these functional limitations.
Examining single limb support provides information about how effectively a person maintains balance while one lower extremity bears weight and the other advances. Clinicians can use this phase to identify weakness or impaired balance and to recognize effects associated with musculoskeletal or nervous system conditions.
Findings from gait assessment can help clinicians identify the functional problems that rehabilitation should address, particularly weakness or impaired balance. The same information supports decisions about assistive devices and provides a basis for tracking whether control and gait performance improve during recovery from injury or surgery.
Changes in single limb support can serve as a functional measure during recovery. Clinicians can assess whether the patient is regaining the balance, lower-extremity control, and forward progression required for gait. These observations help measure recovery after injury or surgery and can inform continuing rehabilitation or assistive-device decisions.
