A Taiwanese research team has found that follicular fluid released from ovulation can cause genetic changes related to ovarian cancer, and that the cancer-causing substance originates from the fallopian tube fimbriae rather than the ovaries.
The research report on risk factors for ovarian high-grade serous carcinoma compiled by Hualien Tzu Chi Hospital’s Department of Obstetrics and Gynecology was published in the journal Carcinogenesis: Integrative Cancer Research.
Department of Obstetrics and Gynecology director Chu Tang-yuan (朱堂元) on Friday said that, when released from ovulation, follicular fluid — which contains high levels of reactive oxygen species — can cause mutation of the umbrella end of the fallopian tube.
After cervical cancer, ovarian cancer causes more deaths than any other cancer of the female reproductive system in Taiwan. An average of 1,300 women are diagnosed with ovarian cancer every year, according to statistics released by the hospital.
The high-risk group for ovarian cancer includes women who start menstruating early or menopause late, have a low number of childbirths, suffer from stress, sleep disorders, or have a family history of ovarian or breast cancer.
The research team also found methods to prevent the gene mutations by using physiological concentration of melatonin, a potent antioxidant.
Experiments on mice have proved effective, the team said.
A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
POLICE INVESTIGATING: A man said he quit his job as a nurse at Taipei Tzu Chi Hospital as he had been ‘disgusted’ by the behavior of his colleagues A man yesterday morning wrote online that he had witnessed nurses taking photographs and touching anesthetized patients inappropriately in Taipei Tzu Chi Hospital’s operating theaters. The man surnamed Huang (黃) wrote on the Professional Technology Temple bulletin board that during his six-month stint as a nurse at the hospital, he had seen nurses taking pictures of patients, including of their private parts, after they were anesthetized. Some nurses had also touched patients inappropriately and children were among those photographed, he said. Huang said this “disgusted” him “so much” that “he felt the need to reveal these unethical acts in the operating theater
