上夜班易患癌
上夜班易患癌
熬夜会伤身，加拿大魁北克大学的最新研究发现，上夜班的男性比在白天工作的男性，更容易患上前列腺癌，几率高出近3倍。
此外，夜间工作的男性，也更可能患上其他癌症，肠道、膀胱及肺部出现肿瘤的几率尤其高。
研究分析了3137名患癌男性的工作情况，发现上夜班的男性，患肠癌的风险会加倍，患肺癌和尿道癌的风险，也分别高出76％和70％。
在夜间工作至少10年的男性，患癌风险最高。
研究员指出，人体会在夜晚来临时，释放退黑激素（melatonin），帮助人们入睡，但是，在夜晚工作时却会接触到亮光，这可能会干扰退黑激素的产生，从而影响健康，提高出现肿瘤的风险。

Green tea may protect against Parkinson's disease
Green tea may protect against Parkinson's disease
Researchers at NUS Yong Loo Lin School of Medicine have identified an activation process between a component in green tea and a protein in the human body that can provide cellular protection against Parkinson's disease.
Called EGCG, the green tea component is also found in red wine, and it triggers AMP kinase, a protein in the body, to help prevent brain cells from dying under stress.
The researchers experimented on engineered fruit flies which had developed Parkinson's, a progressive and degenerative neurological disease.
The team found that EGCG-treated flies exhibit much better movement ability and show significant preservation of their brain neurons, compared to untreated flies.
In three to five years' time, the researchers will move from experimenting on fruit flies to experimenting on mice as well as brain cells from patients with Parkinson's disease.
The team hopes to partner with pharmaceutical companies to formulate a drug which can be administered to Parkinson's disease patients.
Associate Professor Lim Kah Leong from the school's Department of Physiology says current treatment for Parkinson's is usually in the form of a drug known as L-DOPA, which only offers symptomatic therapy.
The potential medication would offer neuro-protection.
Associate Professor Lim said: "Whilst they can actually improve the symptom, current medication cannot stop, cannot reverse the degeneration process. Hence it's important to come up with something that can offer real protection to the brain cells from dying.
"There are benefits of drinking green tea but in this case we have something even more potent than drinking green tea. So hopefully medication centred around AMPK activation can provide real and faster benefit to Parkinson's patients than green tea could at that stage."
Associate Professor Lim added that if a drug were to be developed, it would target patients with early-stage Parkinson's disease to protect their brain cells from further damage.
The study is supported by the Singapore Millennium Foundation, National Medical Research Council and A*STAR Biomedical Research Council. About S$200,000 was put into the project.

这7种教养方式 会断送女儿前途
这7种教养方式 会断送女儿前途
现代女性要争取和男性一样的薪酬待遇，仍然不易，要如何教育出能在职场上立足的女儿呢？
美国REALgirl工作坊创办人柏格（Anea Bogue）提醒，父母应避免7种错误的教养方式，以免误了女儿的前途。
不要这样教女儿
教她温文儒雅：家长在教女儿要有礼貌时，也应鼓励她们勇于发言及为自己辩护，别让她们逆来顺受。
只买女孩的玩具：给女生的玩具有31％强调外表与妆扮。给男生的玩具却鼓励创新探索、竞争等技能。
告诉她外表胜于一切：家长应真心赞美女儿在课业、体育或音乐等方面的成就。
灌输公主梦：应鼓励女儿掌握自己的命运，摆脱“女人的价值由男人来决定”的观念。
爸爸包办体力活：不应以性别来分担家务类别，不妨让女儿除草和倒垃圾，叫儿子洗碗和吸地。
只让她和同性朋友玩：研究显示，学龄前女童只和同性朋友玩，往往比较倾向于合作与妥协。
在她面前批评女性身材：这样会让她以为，拥有特定外形的女性才会受人喜爱及取得成功。
