“柳葉刀”雜志3月份發表了世界衛生組織在法國的國際癌癥研究所(IARC)一篇論文,聲稱全球應用最廣泛的除草劑草甘膦屬于較高致癌的農藥(分類為2A)。一些人以為這是對轉基因技術安全性的致命打擊。關于草甘膦的事實真相究竟怎樣呢?本文參考《致癌性:草甘膦弱于美酒》、《福布斯專欄:不靠譜的聯合國評估》。
1、按照世界衛生組織的國際癌癥研究所(IARC)所分級,單從致癌性看,喝草甘膦水溶液比曬太陽、喝葡萄酒、五糧液、吃咸魚等我們常吃的食品都還要安全。
2、IARC無權決定草甘膦是否可以安全施用,這[查看]

近日,國際學術期刊nature communication在線發表了中國醫學科學院和北京協和醫學院研究人員關于應用單克隆抗體治療H7N9禽流感病毒的最新研究進展,這項研究對于H7N9禽流感病毒預防和治療,預防H7N9禽流感病毒大流行具有重要意義。
2013年2月,H7N9禽流感病毒亞型在中國華東地區出現,隨后不久出現人感染H7N9病毒的情況,人感染H7N9禽流感會引起發熱,咳嗽,有痰等急性呼吸道傳染病癥狀,并造成重癥肺炎,嚴重者可導致死亡。H7N9禽流感病毒的爆發嚴重威脅公眾健康,但目前預防和控制人感染H7N9禽[查看]

2013年,習近平總書記在會見世界衛生組織總干事時表示:“愿與世衛組織繼續加強雙方合作,促進中西醫結合及中醫藥在海外發展,推動更多中國生產的醫藥產品進入國際市場”。2014年國務院法制辦就《中華人民共和國中醫藥法(征求意見稿)》向社會公開征求意見。其宗旨是為繼承和弘揚中醫藥,扶持和促進中醫藥事業發展,保護公眾健康。此稿一出引發了業內極大的關注。
在這樣的背景下,今年兩會期間,代表們就加速中藥標準化、現代化、國際化,以及中醫藥標準化體系及中醫藥法規體系的完善等提出了一系列建議,涉及到中藥經典[查看]

專家認為盡早開展實驗室合作可有效杜絕此類假警報
將科學保密性調整到不同尋常的水平,仿佛是對生物安全性的嚴重新威脅,但并非如此。2013年,美國加州公共衛生局(CDPH) 的Stephen Arnon報告稱發現了一種新型肉毒桿菌毒素,沒有抗菌素能有效防御這種毒素。一旦生物恐怖主義者能夠生產這種化合物,并通過食物或空氣將其散播出去,社會對其可能根本沒有防御能力。要抵御這種威脅,Arnon決定不在論文中披露這種細菌的基因序列,這一舉動引發大量媒體的關注。
但去年年底,美國政府機構的研究人員推斷,沒有必要保密,因為這種[查看]

抗藥菌一直都是讓醫院、乃至醫藥產業頭疼的問題。現在,眾多的生物醫藥公司都在研究如何才能夠徹底根治這一頑疾。不過,目前看來似乎這一目標仍然是遙遙無期。既然這一方法暫時無解,能否采用另外一個思路來降低抗藥菌傳播的風險?最近法國的科學家就在這條路上做出了有益的嘗試。
科學家使用無線設備來追蹤包括261名醫療工作者和329名患者在內的受試者在醫院中的活動。這些受試者佩戴的無線傳感器每三十秒就會記錄這些受試者的位置以及與其他受試者是否發生接觸。
然后,研究人員每周從患者鼻部采集樣本檢測抗藥型葡萄球菌的痕跡。經過四個月的跟[查看]

干細胞具有強烈的身份認同感。例如,從毛囊住所處取出干細胞,將它們置于培養基中培養,這些細胞仍然會保持真實的自我。在過渡狀態下等待一段時間后,一旦將它們移植回皮膚,這些培養細胞能夠再生出毛囊以及其他的皮膚結構。然而人們并不清楚這些干細胞(以及身體其他部位的干細胞)是如何在特殊的環境中保持生成新組織及愈合傷口的能力的。
來自洛克菲勒大學的一項新研究發現一個蛋白Sox9主導控制了細胞的可塑性。在發表于3月10日《自然》(Nature)雜志上的一篇研究論文中,該研究小組將Sox9描述為是一個“先鋒因子&rdq[查看]

【新聞事件】:今天早晨百建艾迪宣布其阿爾茨海默(AD)藥物,淀粉狀蛋白抗體aducanumab(代號BIIB037)在一個一期臨床實驗中表現出色。根據不同測試方法,使用54周最高劑量aducanumab的病人比安慰劑組病人認知功能障礙惡化緩解70-80%,這遠高于專家估計的20-30%緩解。雖然55%的ApoE4基因攜帶者(高危人群)使用最高劑量aducanumab有腦腫脹副作用,但百建艾迪股票還是飆升8%。自去年12月百建艾迪宣布aducanumab的積極療效其市值已增加了350億美元。

上周四,納斯達克生物科技股指數在3500點盤旋,處于歷史高位,引起一些投資者再次呼叫“狼來了”。
據彭博社報道,上周四,生物科技股占到納斯達克總市值的11.2%,險勝互聯網公司和硬件制造商。在過去四年,269家生物科技公司一直是納斯達克主力,股價平均上漲了500%,高于硬件制造商166%的漲幅以及互聯網公司97%的漲幅。
現有跡象表明,生物科技產業的命運可能發生改變。根據彭博社數據顯示,被稱為投資者悲觀情緒“晴雨表”的一個關鍵指標 - 短期利率自2013年來已經翻[查看]

吡啉相關周期熱綜合征(CAPS)是一類嚴重的自身免疫性疾病,它的病因是調控先天免疫反應的重要原件-炎癥小體-一個蛋白質成分NLRP3發生了獲得性病變。不僅如此,NLRP3的突變對于2型糖尿病、多發性硬化,阿茲海默癥,痛風,動脈粥樣硬化等復雜的疾病也有負面的影響。
大約在十年之前,NLRP3炎癥小體作為一類先天免疫系統中的重要調節元件被科學家們鑒定出來。這個蛋白質復合體由NOD Like Receptor家族蛋白NLRP3,接口蛋白ASC以及caspase1三類蛋白組成,主要在髓系淋巴細胞中發揮功能。NLRP3炎癥[查看]

霧霾到底會不會致癌?紀錄片《穹頂之下》的一組數據顯示,中國過去十年里肺癌發病率增長了300%。霧霾就是導致我國肺癌發病率激增的主要“元兇”?在全國政協委員、中國電力科學研究院副總工程師蔡國雄委員看來,“這是一種誤解,科學事實并非如此。”
蔡國雄委員告訴科技日報記者,空氣污染、霧霾跟癌癥(肺癌)發病率是有關聯的,但這種關聯機制現在醫學上尚不能證實,而柴靜團隊忽略的另一份統計數據顯示霧霾和癌癥之間的關聯程度遠遠比不上年齡和癌癥的關聯程度。

制藥與生物技術行業在2014年創下了驚人的并購紀錄,其中企業對交易的渴求是一方面原因,股票市場的大漲以及對資產的激烈競爭促使估值攀升,也是重要的促成因素。
此外,通過對行業中那些一擲千金的企業的仔細觀察,盡管大型藥企對并購依舊普遍持謹慎態度,但有些公司已經愿意重新回到談判桌上。
股市繁榮抬升并購成本
一項針對并購金額低于200億美元的交易的分析指出,去年藥企之間交易的平均標價飆升了39%,達到9.11億美元。進一步深入探究EvaluatePharma的數據顯示,中型規模的并購案數量大幅猛增。

2月19日,美國藥品管理局(FDA)批準了"23 and me"公司發明的,對引起"布魯姆綜合征"(一種可能導致身材矮小并伴隨高發性癌癥的疾病)的主效基因進行檢測手段。
這一檢測手段主要針對準備生育的人群。如果雙親這一基因都具有"BLMAsh"表型的話,子女就會出現這一癥狀。一般情況下發生的幾率微乎其微,然而,當雙親均為德裔猶太人時,概率上升至1/50000。這一件測手段被認為屬于一種攜帶者監測,用于檢測是否雙親攜帶這一遺傳特征。
