實(shí)驗(yàn)室又要開始測實(shí)驗(yàn)動物的體溫了,師兄師姐們開始唉聲嘆氣:幾十只小動物,每隔五分鐘記錄一次體溫,連續(xù)測量十二小時的體溫變化。。。
用紅外線體溫計或接觸式體溫探頭測量小動物的體溫,它們身上那層平時讓你擼起來愛不釋手的毛茸茸,成了體溫計與皮膚直接的阻礙,想要他們親密接觸,還要一只只給小動物們剃毛,一不小心一個噴嚏下來,毛毛滿天飛。這就算了,還要隔幾分鐘測量一次體溫,操作簡單而繁瑣,一不小心時間看錯了,又得重新來!
用肛溫計測量動物的直腸溫度吧,結(jié)果會更準(zhǔn)確,但需要讓動物處于麻醉狀態(tài)。這一步驟卻直接導(dǎo)致實(shí)驗(yàn)操作更復(fù)雜:或麻醉過深,動物直接死亡,或麻醉過淺,動物在實(shí)驗(yàn)途中醒來;實(shí)驗(yàn)過程也不能長,至多只能獲得幾小時的體溫變化,在實(shí)驗(yàn)過程中還要注意溫度計探頭是否移動或掉出,而且麻醉本身就會影響小動物們的體溫。當(dāng)體溫計不能直接保存數(shù)據(jù)的時候,還要一個個記錄數(shù)據(jù)。。。
想想這工作量,可不就讓各位師兄師姐們抓頭撓耳的嗎?頭發(fā)都愁的掉了一大把,發(fā)際線蹭蹭往上移!
當(dāng)你想要長時間,多頻率地連續(xù)測量動物體溫變化的時候,你是不是感到很頭疼,不知道怎么才能得到想要的數(shù)據(jù)呢?安利一款可多通道、無線式檢測體內(nèi)溫度利器——Anipill® 體溫膠囊,輕松實(shí)現(xiàn)動物體溫監(jiān)測,掃描下方二維碼即可試用。
Anipill® 體溫膠囊基于使用微型傳感器準(zhǔn)確測量生理參數(shù),將測得的數(shù)據(jù)連續(xù)無線地發(fā)送到便攜式設(shè)備,允許遠(yuǎn)程監(jiān)控。其體積小,無害,高精度,壽命長,可遠(yuǎn)距離傳輸等優(yōu)點(diǎn)不僅解決了傳統(tǒng)方式記錄體溫耗時的問題,還避免了多次重復(fù)操作對動物造成壓力影響數(shù)據(jù)收集現(xiàn)象,從而深受客戶的喜愛,目前已有較多相關(guān)文獻(xiàn)發(fā)表于 Nature、Elsevier 等諸多 Sci 期刊上(相關(guān)文獻(xiàn)見文末)。
為什么選擇 ANIPILL® ?
操作簡單,舒適性強(qiáng)
該解決方案由生理學(xué)家參與開發(fā),使產(chǎn)品在舒適性和易用性得到很好地結(jié)合:開始啟動后,自動采樣并傳輸、保存數(shù)據(jù),連接電腦即可查看數(shù)據(jù)。
采樣精確,數(shù)據(jù)可靠
Anipill® 是一種小型電子膠囊,便于中型物種吞食,也可簡單地植入小型動物,如小鼠(起始重量為 20 g),實(shí)時通信技術(shù)使您能夠連續(xù)訪問從專門的監(jiān)測儀 Anilogger® 收集的數(shù)據(jù),每個膠囊的內(nèi)嵌存儲器確保突發(fā)情況下與監(jiān)測儀的通信中斷時可恢復(fù)所有其收集的數(shù)據(jù),比方說在正常生命狀況下的測量期間通信中斷,數(shù)據(jù)同步后可以恢復(fù)所有測量的溫度值,而不會丟失數(shù)據(jù)。
多線程操作,更高效
ANIPILL® 膠囊可在啟動完成后和 AniLogger® 監(jiān)測儀的配對,1 臺監(jiān)測儀可同時追蹤 8 個膠囊,膠囊的工作時長為 20 天至 10 個月(具體取決于所選的采樣周期),確保同時批量完成數(shù)據(jù),減少實(shí)驗(yàn)成本,此外設(shè)備可與 PC 和 MAC 兼容的接口,方便后續(xù)對收集數(shù)據(jù)進(jìn)行存檔或臨床操作;
保障動物福祉
尊從保障動物福祉的原則,有效減少對動物進(jìn)行處理,施加壓力和限制條件,保持其團(tuán)隊流動性及生活條件,進(jìn)一步確保數(shù)據(jù)可靠性。
應(yīng)用領(lǐng)域
AniLogger® 解決方案持續(xù)監(jiān)控動物體內(nèi)溫度,目的是為了了解動物的生理機(jī)制或監(jiān)測其發(fā)熱狀態(tài)。該設(shè)備不但適用于收集藥物/疫苗學(xué)數(shù)據(jù),而且也適用于分析生物節(jié)律,休眠或溫度調(diào)節(jié)過程。
? 藥理學(xué)研究:
監(jiān)測溫度對于傳染病/病毒傳染的研究醫(yī)治是至關(guān)重要的,對溫度動力學(xué)的分析有助于更好地了解活性物質(zhì),醫(yī)治方法或病理學(xué)是如何影響動物調(diào)節(jié)其體溫能力的。
? 休眠研究:
休眠是動物的生命功能保持在較差狀態(tài)的生物條件,這相當(dāng)于一段冬季的深度睡眠時間。期間,動物經(jīng)歷了一系列生理變化(體溫過低,基本功能降低 … )。
? 生物節(jié)律分析:
體內(nèi)溫度是生物節(jié)律的關(guān)鍵指標(biāo),對這一變量的持續(xù)監(jiān)測允許對體內(nèi)溫度晝夜節(jié)律(分析生物節(jié)律和睡眠失調(diào)的基本工具)進(jìn)行表征。
? 溫度調(diào)節(jié)機(jī)能分析:
溫度調(diào)節(jié)機(jī)能學(xué)是一個主要的科學(xué)軸,重點(diǎn)研究主體對不同的內(nèi)部或外部刺激的反應(yīng)。了解其基本機(jī)制非常重要,因?yàn)樗鼈儾粌H影響體內(nèi)和體外溫度,也影響其他生理變量,如心率,血壓等。

1.IL-17a promotes sociability in mouse models of neurodevelopmental disorders
Nature volume 577, pages249–253(2020)
Tracking of body temperature Body temperature was measured using the Anipill remote temperature monitoring system (007894-001, DSI). Adult male mice were implanted with an Anipill capsule in the abdominal cavity. Experiments were carried out more than three weeks after surgery. Mice were singly housed the day before the experiment. Ambient temperature was maintained at 23.5 °C, consistent with the ambient temperature of the vivarium. Body temperature was sampled in 5-min increments. LPS or vehicle injections occurred between 11:00–13:00 for experiments assaying the effects of LPS on body temperature in PBS and MIA offspring.
2.Effect of non-thermal radiofrequency on body temperature in mice
Scientific Reports volume 10, Article number: 5724 (2020)
Anipill transmitter implantation. Body temperature of mice was recorded by using Anipill loggers (1.7 g weight and 8.2 mm diameter, 17.2 mm length) (BodyCap, Paris, France) to obtain temperature data from freely-moving mice.
3.Continuous and non-invasive thermography of mouse skin accurately describes core body temperature patterns, but not absolute core temperature
Scientific Reports volume 10, Article number: 20680 (2020)
Methods
All animal procedures were approved by the ACER AWERB of the University of Oxford and performed under a UK Home office license in accordance with all relevant laws and regulations. Five wildtype C57Bl6/J mice were implanted intraperitoneally with anAnipill temperature telemeter. Following post-operative recovery mice were housed at an ambient temperature of 22 ± 1 °C in open-top cages, each positioned under a thermal camera. Tskin was measured every second by storing the temperature of the warmest pixel. Tcore was measured every 30 s by the implanted Anipill.
4.PGC-1β-expressing POMC neurons mediate the effect of leptin on thermoregulation in the mouse
Scientific Reports volume 10, Article number: 16888 (2020)
Cold exposure and norepinephrine tests. For cold exposure challenge, animals were individually placed and acclimatized to CLAMS cages in early daytime with free access to water but no food for at least 6 h at 23 °C. Five days later, animals were placed in pre-cooled CLAMS cages without food access for 6 h at 4 °C. Core body temperature measurements were obtained using Anipill Temperature Implant (Phymep).
5. Maximising survival by shifting the daily timing of activity
Ecology Letters Volume 22, Issue 12 p. 2097-2102 Letter
Body temperature recordings were performed for ~ 2 months in a separate population of mice implanted intraperitoneally with Anipill temperature data loggers. All measurements were performed in both male and female mice. An extensive description of methodological details is available in the Supporting Information.
