Elucidating the Staphylococcus aureus TSST‐1 Regulatory Network as a Response to Vaginal pH

Molecular Microbiology, Volume 126, Issue 2, Page 220-235, August 2026.
Toxic shock syndrome toxin‐1 (TSST‐1) is a potent Staphylococcus aureus superantigen responsible for menstrual toxic shock syndrome (mTSS). Regulation of TSST‐1 is controlled by multiple systems including the stand‐alone transcriptional regulators CcpA and SarA and two‐component systems including the redox sensor SrrAB, the membrane stress sensor SaeRS,

Evaluating the Reliability and Consistency of Treadmill Gait Analysis Using an RGB-D Camera: Effects of Assistance and No Assistance

Sensors
This study aimed to assess the intraday reliability of markerless gait analysis using an RGB-D camera versus a traditional three-dimensional motion analysis (3DMA) system with and without a simulated walking assistant.

Markerless Camera Pose Estimation - An Overview.

, 2011
As shown by the human perception, a correct interpretation of a 3D scene on the basis of a 2D image is possible without markers. Solely by identifying natural features of different objects, their locations and orientations on the image can be identified. This allows a three dimensional interpretation of a two dimensional pictured scene.

Marker Data Enhancement For Markerless Motion Capture

IEEE Transactions on Biomedical Engineering
Abstract Objective Human pose estimation models can measure movement from videos at a large scale and low cost; however, open-source pose estimation models typically detect only sparse keypoints, which leads to inaccurate joint kinematics.

6-Degree Vision based Tracking of a Mandible Phantom with Deep Learning

Current Directions in Biomedical Engineering
During maxillofacial surgery, the precise placement of surgical tools is crucial for accurate implant placement. Particularly if multiple implants are needed, e.g., after cancerous bone removal, visual landmarks might not be obtainable.

Early Motor Pattern Analysis Using a Single RGB-D Camera: A Case Study of Twins at Divergent Risk for Motor Impairment

IEEE Open Journal of Engineering in Medicine and Biology
Early identification of motor impairment in infants at developmental risk can benefit from objective assessment methods. In this feasibility study, we evaluated quantitative kinematic metrics extracted from home-based recordings as indicators of ...

Comparison of Marker-Based and Markerless Motion Capture Systems for Measuring Throwing Kinematics

Biomechanics
Background: Marker-based motion capture systems are commonly used for three-dimensional movement analysis in sports. Novel, markerless motion capture systems enable the collection of comparable data under more time-efficient conditions with higher ...

Projector Calibration using a Markerless Plane.

, 2009
In this paper we address the problem of geometric video projector calibration using a markerless planar surface (wall) and a partially calibrated camera. Instead of using control points to infer the camera-wall orientation, we find such relation by efficiently sampling the hemisphere of possible orientations. This process is so fast that even the focal

Associations Between Hip Mobility and Pain in Chronic Low Back Pain Using IMU and Markerless Motion Capture

Sensors
Introduction: Chronic non-specific low back pain (CNLBP) is associated with altered lumbopelvic mechanics and impaired hip mobility. This study examined whether changes in pain-provoking hip flexion are associated with changes in low back pain and ...
