Real-Time Wireless Detection of Heavy Metal Ions Using a Self-Powered Triboelectric Nanosensor Integrated with an Autonomous Thermoelectric Generator-Powered Robotic System.

The integration of the Internet of Things (IoT) with advanced sensing technologies is transforming environmental monitoring and public health protection. In this study, a fully self-powered and automated chemical sensing system is developed and integrated with a robotic hand for "touch and sense" detection of toxic heavy metal ions (Pb⁺, Cr⁶⁺, As⁺) in aquatic environments. The system combines a self-powered solid-liquid triboelectric nanosensor (SL-TENS) with a thermoelectric generator (TEG), which harnesses ambient heat to power the robotic hand, eliminating the need for external power sources.

[Analysis on the expression of human papillomavirus type 16 E2 and E6 oncogenes and disruption of E2 in cervical cancer].

Objective: To evaluate the roles of expression and early protein E2 and E6 load of human papillomavirus type 16 (HPV16) on cervical cancer in order to explore the relation between disruption of E2 and development of cervical cancer.

Methods: A case-control study was conducted, including 141 cervical cancer patients as cases who had been diagnosed by cytological approaches and histological approaches in Shanxi province Tumor Hospital, China. Two type of controls including 137 hospital controls with hysteromyoma by cytology or histology and eligible 129 controls from 1582 healthy women in the community who took part in community-organized physical examination with neither CIN2-3 nor invasive cancer, nor other gynecologic diseases were recruited.

[Association between endogenous hormones, hormone receptors and cervical cancer].

Objective: To explore the relationship between the levels of estrogen (E2) and progestogen (P), expression of estrogen receptor (ER) and progesterone receptor (PR) and cervical cancer.

Methods: A case-control study with hospital and community controls was employed. The levels of serum estrogen and progesterone were detected by enzyme linked immunosorbent assay (ELISA) for 141 cervical cancer cases, 137 uterine myoma patients as controls and 129 health women as controls.

[A case-control study on the association between folate and cervical cancer].

Objective: To evaluate the possible effects of folate on cervical carcinogenesis and the interaction of folate and human papillomaviruses 16 (HPV16).

Methods: A hospital-based case-control study was conducted. 111 hospitalized cases who were pathologically diagnosed of having cervical cancer and 111 controls identified with hysteromyoma that frequency-matched to cases on age, birth place and residential area.

[Analysis on synergistic action between estrogen, progesterone and human papillomaviruses in cervical cancer].

Objective: To explore the effects of estrogen (E(2)) and progesterone (P) on cervical cancer and the synergistic action between estrogen, progesterone and human papillomaviruses (HPV).

Methods: Hoted-start polymerase chain reaction (HS-PCR) was used to detect HPVs, HPV16 and ELISA was used to assay E(2) and P on 141 cases with cervical cancer and on 129 healthy controls.

Results: Positive rates of HPVs and HPV16 were 75.
