Testicular histological evaluation and serum testosterone concentrations of bulls after chemical castration with calcium chloride

open access: yesPesquisa Veterinária Brasileira
: Orchiectomized bulls have advantages in the meat quality and ease of handling. Chemical castration is an option for surgical castration and the sclerosing agents can be administered into the testicular or epididymis parenchyma.

Analysis of Beta-Lactoglobuline Gene (LGB) Polymorphism in Different Breeds of Bulls by High Resolution Melting

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The goal of the paper was to identify b - lactoglobulin gene polymorphism in bulls. The b - lactoglobulin (LGB) is expressed in milk and is important in the evaluation of milk production potential and butterfat and protein content.

Interactive Prompt‐Guided Robotic Grasping for Arbitrary Objects Based on Promptable Segment Anything Model and Force‐Closure Analysis

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A laser pointer‐guided robotic grasping method for arbitrary objects based on promptable segment anything model and force‐closure analysis is presented. Grasp generation methods based on force‐closure analysis can calculate the optimal grasps for objects through their appearances. However, the limited visual perception ability makes robots difficult to

Skin‐Conformal Myography for Real‐Time Hand Tracking Using a Laser‐Induced Graphene Strain Sensor Array

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A skin‐conformal wearable device based on laser‐induced graphene is developed for continuous strain measurement across the circumference of the forearm for gesture recognition and hand‐tracking applications. Post material optimization, the strain sensor array is integrated with a wearable wireless readout circuit for real‐time control of a robotic arm,

Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

open access: yesAdvanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.

Optical Fiber‐Based Versatile Wearable Force Myography System: Application to Human–Robot Interaction

open access: yesAdvanced Intelligent Systems, EarlyView.
A compact and flexible wearable force myography sensor based on optical fiber technology detects muscle activity through pressure‐induced light loss. The sensor offers high sensitivity for detecting subtle force and finger motion changes, along with excellent signal stability under dynamic and sweating conditions.

Seamlessly Overcoming Biological Barriers with a Small Photosensitizer to Treat Metastatic Tumors with Photodynamic Therapy

open access: yesAngewandte Chemie, EarlyView.
LUZ 51 is a relatively small and amphiphilic photosensitizer that accumulates in poorly‐vascularized tumors, is rapidly internalized by cancer cells, does not elicit skin photosensitivity and triggers robust immunological responses that reduce spontaneous metastasis.
