Lesion Segmentation in Ultrasound Using Semi-Pixel-Wise Cycle Generative Adversarial Nets.

Breast cancer is the most common invasive cancer with the highest cancer occurrence in females. Handheld ultrasound is one of the most efficient ways to identify and diagnose the breast cancer. The area and the shape information of a lesion is very helpful for clinicians to make diagnostic decisions.

Probabilistic Kinematic Model of a Robotic Catheter for 3D Position Control.

Continuum robots offer compliant and dexterous operations, which are suitable to be used in unstructured environments. Tendon-driven catheters, owing to their continuum structure, are applied in minimal invasive surgeries such as intracardiac interventions. However, due to the intrinsic nonlinearities and external disturbances, it is still a challenging task to accurately steer the catheter tip to the desired 3D positions.

Surgical robotics beyond enhanced dexterity instrumentation: a survey of machine learning techniques and their role in intelligent and autonomous surgical actions.

Purpose: Advances in technology and computing play an increasingly important role in the evolution of modern surgical techniques and paradigms. This article reviews the current role of machine learning (ML) techniques in the context of surgery with a focus on surgical robotics (SR). Also, we provide a perspective on the future possibilities for enhancing the effectiveness of procedures by integrating ML in the operating room.

Purification, quantification, and functional analysis of Complement Factor H.

Complement Factor H (FH) is an abundant, non-enzymic plasma/serum glycoprotein, which has a major role in regulating activation of the complement system. It can be purified from human plasma/serum by affinity chromatography, using a monoclonal anti-FH antibody as ligand. Other affinity chromatography ligands, including cardiolipin and trinitrophenyl-bovine serum albumin (TNP-BSA), can be used to purify human FH and also FH from a wide range of vertebrates, including mammals, birds, bony fish.

Complement activation by phospholipids: the interplay of factor H and C1q.

Complement proteins in blood recognize charged particles. The anionic phospholipid (aPL) cardiolipin binds both complement proteins C1q and factor H. C1q is an activator of the complement classical pathway, while factor H is an inhibitor of the alternative pathway.

[Study on the properties of solid substrate room temperature phosphorescence of the antibody labeled with fluorescein isothiocynate].

The properties of room temperature phosphorescence (RTP) of the labeled goat anti-human antibody(with fluorescein isothiocynate GAHAb-FITC) and labeled rabit anti-goat antibody(RAGAb-FITC) with FITC in different dilution ratios on many kinds of solid substrates were studied in detail. It is found that on the polyamide membrane, only using Pb(Ac)2 as a heavy atom perturber, both the labeled antibodies and their antigen-antibody conjugated compound with the human immunoglobulin G remained excellent RTP properties of isothiocyanate fluorescein, lambda ex(max)/lambda em(max) = 525/650 nm, the relation of RTP intensity to the concentration was linear in a certain range. The conditions for immunological reaction and RTP emission were optimized.
