Objective: To explore the impact of biomimetic electrical stimulation combined with Femoston (estradiol tablets/estradiol and dydrogesterone tablets) on pregnancy rate and endometrium characteristics (endometrial thickness and type) in patients with infertility and a thin endometrium.
Methods: This prospective study enrolled patients with infertility and a thin endometrium admitted to Urumqi Maternal and Child Health Hospital of Xinjiang Uygur Autonomous Region, Urumqi, China, between May 2021 and January 2022. The patients received Femoston alone (Femoston group) or Femoston combined with biomimetic electrical stimulation (electrotherapy group). The outcomes were the pregnancy rate and endometrium characteristics.
Results: Finally, 120 patients were enrolled (60/group). Before treatment, the endometrial thickness ( = 0.515) and the percentages of patients with endometrial types A + B and C ( = 0.769) were comparable between the two groups. After treatment, the endometrium of the patients in the electrotherapy group was thicker than those in the Femoston group (6.48 ± 0.96 mm vs. 5.27 ± 0.51 mm, < 0.001). Furthermore, the percentages of patients with endometrial types A + B and C in the electrotherapy group were larger than in the Femoston group ( = 0.027). In addition, the pregnancy rates between the two groups (28.33% vs. 16.67%, = 0.126) were similar.
Conclusions: The results suggest the possibility that biomimetic electrical stimulation combined with Femoston could improve endometrial type and thickness in patients with infertility and thin endometrium compared with Femoston alone, but the pregnancy rate showed no significant improvement. The results need to be confirmed.

Omnidirectional strain sensing and direction recognition ability are features of the human tactile sense, essential to address the intricate and dynamic requirements of real-world applications. Most of the current strain sensors work by converting uniaxial strain into electrical signals, which restricts their use in environments with multiaxial strain. Here, the first device with simultaneous isotropic omnidirectional hypersensitive strain sensing and direction recognition (IOHSDR) capabilities is introduced.

Background: Both oxidative stress and autoimmune responses play crucial roles in the development of vitiligo. Under oxidative stress, the apoptotic melanocytes expose self-antigens and release high mobility group box 1 (HMGB1), triggering autoimmune activation and recruiting CD8 T cells. This process further leads to the destruction of melanocytes, resulting in the lack of melanin granules.

Implantable neural electrodes are key components of brain-computer interfaces (BCI), but the mismatch in mechanical and biological properties between electrode materials and brain tissue can lead to foreign body reactions and glial scarring, and subsequently compromise the long-term stability of electrical signal transmission. In this study, we proposed a new concept for the design and bioaugmentation of implantable electrodes (bio-array electrodes) featuring a heterogeneous gradient structure. Different composite polyaniline-gelatin-alginate based conductive hydrogel formulations were developed for electrode surface coating.

Soft robots are usually manufactured using the pouring method and can only be configured with a fixed execution area, which often faces the problem of insufficient or wasteful performance in real-world applications, and cannot be reused for other tasks. In order to overcome this limitation, we propose a simple and controllable rather than redesigned method inspired by the bionic growth behavior of plants, and prepare bionic soft robots that can just meet the requirements of use, and transform biological intelligence into mechanical intelligence. Based on finite element method, we establish a theoretical model of soft robot performance.

Flapping wing micro aerial vehicles (FWMAVs) are recognized for their significant potential in military and civilian applications, such as military reconnaissance, environmental monitoring, and disaster rescue. However, the lack of takeoff and landing capabilities, particularly in landing behavior, greatly limits their adaptability to the environment during tasks. In this paper, the purple stem beetle (), a natural flying insect, was chosen as the bionic research object.
