FEBS Open Bio, EarlyView.NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

A study of power performance of the average shifted Chi-square test for goodness of fit [PDF]
, 2010 碩士當給定一組隨機觀測值 ，如欲檢定它們是否來自某特定連續型母體分布，稱為適合度檢定(goodness of fit test )，其中卡方檢定(Pearson chi-square test) 為常見的方法。使用卡方檢定時須先給定樣本空間的分組數(number of partition)，再計算每個組別中的期望次數和理論次數的差異，作為卡方檢定統計量，因檢定統計量會受到起始點選擇的影響，造成統計量不穩定。此外，樣本空間的分組，使得樣本資訊損失造成檢定力下降的問題，由於上述兩缺點，Wu and Deng

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Attuali sviluppi nello studio dell’associazione tra variabili di tipo qualitativo.
Ratio Mathematica, 1996 The most common procedure for analyzing contingency table data is by using chi-square statistic. The early development of chi-square analysis of contingency table is credited to Pearson (1904) and Fisher (1929), successively expanded by Yates, Mantel ...

Delivery of DNA‐encoded vaccines and proteins in mice using cutaneous suction‐mediated transfection
FEBS Open Bio, EarlyView.Cutaneous suction‐mediated transfection in mice for delivery of DNA‐encoded vaccines and proteins. A critical limitation of DNA vaccines and other therapeutics is transfection in vivo to produce the encoded antigens or therapeutic proteins. Cutaneous suction‐based methods have demonstrated effectiveness in many animal models and have been successfully ...

Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound
FEBS Open Bio, EarlyView.We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...

Monotonicity of chi-square test statistics [PDF]
, 2003 This paper establishes monotonicity of the chi-square test statistic. As the more efficient parameter estimator is plugged into the test statistic, the degrees of freedom of the resulting chi-square test statistic monotonically ...
