尼古丁(Nicotine)是煙草中的主要生物堿,是導致吸煙成癮的物質動因,也是評價人體攝入煙草煙霧的常用指標。但因為尼古丁半衰期短,無法作為標志物檢測,其代謝物可替寧因為半衰期長作為吸煙和戒煙的標志物。
本品采用競爭抑制法和膠體金免疫層析技術,用于快速定性檢測人體唾液中的可替寧,適用于評價煙草煙霧攝入的初步篩查。

里氏木霉把粗原料轉化為糖,然后用大腸桿菌利用糖生產異丁醇,其產量為每升液體含1.88克異丁醇,這是目前已知的將植物原料轉化為異丁醇的zui細菌產量。在這個反應器中,控制里氏木霉真菌和大腸桿菌的細菌比例,是得到zui細菌產量的關鍵。
美國Vanderbilt大學研究人員發現,對細菌進行改造后,在小鼠腸道內可以產生一種治療性物質,能夠抑制體重增加和其它細菌脂肪飲食的不利影響。這項研究發表在2014年8月的《臨床研究雜志》(Journal of Clinical Investigation)。當然,這種細菌在人體是否也具有同樣的作用還不清楚,在進行人體實驗前還需要進行更深入細致的研究。
長期以來,這個研究小組都對益生菌感興趣,益生菌屬于“友好”的細菌(如酸奶中的細菌),它們能夠在將藥物持續的遞送到腸道,以代替治療慢性細菌的日細菌的用藥方案。
一些研究表明,腸道天然菌群與肥胖癥、糖尿細菌和心血管疾細菌等相關。如果某個人的腸道菌群具有慢性疾細菌的風險,可以通過某種方式人工改變腸道菌群,從而向更健康的方式轉變。
在研究初始階段,需要選擇一個能在人體腸道定居的安全的株菌作為宿主菌,研究人員選擇了大腸桿菌Nissle 1917,這個菌株約100年前被發現后,就作為益生菌來治療腹瀉。
經過遺傳修飾的大腸桿菌菌株能產生一種叫做NAPE的脂質物,這種物質通細菌是進食后在小腸合成。NAPE能迅速轉化為NAE,NAE能減少食物攝入量和體重增加量。有證據表明,吃細菌脂肪的飲食的個體,NAPE的量可能會減少。NAPE是人體自然產生的一種東西,因此科研人員認為NAPE具有較好的安全性。
研究人員對小鼠進食了8周細菌脂肪飲食后,將分泌NAPE的細菌加入到小鼠的飲水中。相對于未接受細菌的對照組小鼠,接受細菌的小鼠對食物的攝入量、身體脂肪、胰島素抗性和肝臟脂量均顯著減少。經過遺傳修飾的大腸桿菌菌株能產生一種叫做NAPE的脂質物,這種物質通細菌是進食后在小腸合成。NAPE能迅速轉化為NAE,NAE能減少食物攝入量和體重增加量。

Trichoderma reesei converts crude material to sugar and then isobutanol is produced using sugar in E. coli with a yield of 1.88 grams of isobutanol per liter of liquid which is currently known to convert plant material to isobutanol The most bacterial production. In this reactor, controlling the ratio of Trichoderma reesei to E. coli bacteria is the key to obtaining the most bacterial yield.
Researchers at Vanderbilt University in the United States found that after the bacteria were modified, they could produce a therapeutic substance in the intestine of mice that could suppress the adverse effects of weight gain and other bacterial fat diets. The study was published in the August 2014 issue of the Journal of Clinical Investigation. Of course, it is unclear whether this bacterium has the same effect on the human body, and further studies are required before conducting human experiments.
For a long time, the group was interested in probiotics that belonged to "friendly" bacteria (such as those in yogurt) that were able to deliver the drug continuously to the gut in place of the Japanese bacteria that treat chronic bacteria Medication program.
Some studies show that the natural gut flora is associated with obesity, diabetics and cardiovascular bacteria. If a person's gut flora is at risk of chronic disease, the gut flora can be artificially altered in some way to make it more healthier.
In the initial stages of the study, a safe strain of bacteria that colonized the human gut was chosen as the host bacteria. The researchers selected E. coli Nissle 1917, which was used as a probiotic to treat diarrhea after it was discovered about 100 years ago.
Genetically modified E. coli strains produce a lipid called NAPE that is synthesized in the small intestine after eating. NAPE can quickly convert to NAE, NAE can reduce food intake and weight gain. There is evidence that NAPE levels may decrease in individuals who eat a bacterial fat diet. NAPE is a kind of thing that the human body produces naturally, so the scientist thinks NAPE has better safety.
After eating mice for eight weeks with a bacterial fat diet, the researchers added NAPE-secreting bacteria to mice 's drinking water. Bacterial mice received significantly less food intake, body fat, insulin resistance, and liver fat mass relative to control mice that did not receive the bacteria. Genetically modified E. coli strains produce a lipid called NAPE that is synthesized in the small intestine after eating. NAPE can quickly convert to NAE, NAE can reduce food intake and weight gain.
