the Scientific Method has only four key steps. The first is observation. All Science begins with the observation of facts in our environment. Then, after we collect enough information about the development of a certain event in nature, we begin to formulate questions. Questions such as, “why...
Through application of different fixation forms,lengths and tensile speeds of silk samples and comparative analysis of the main performance indexes measured,a method which can correctly evaluate tensile test of mechanical performance of raw material is explored in this paper.The results show: the streng...
Furthermore, a "leave-one-out" analysis was conducted to assess the impact of individual SNPs on the causal relationship between exposure and outcome. In cases where heterogeneity was detected, a random-effects IVW method was utilized to estimate the causal association, while a fixed-effects ...
A method, filter-aided sample preparation (FASP) combines the advantages of in-gel and in-solution digestion for mass spectrometry–based proteomics, allowing deeper proteomic coverage in a shorter analysis time, using small sample amounts. We describe a
The method provided by the invention is beneficial to improve the quality of the blood samples in scientific research application, helps to guarantee accomplishment achieved in subsequential scientific research work and avoid manpower and material resources wastes caused by sample problems. No same kind...

The causal effect between gut microbiota and infertility was primarily assessed using the random-effect inverse variance weighted (IVW) method. As a main analytical approach, IVW estimates were considered to be in a relatively ideal state, with their effectiveness relying on the validity of all ge...
Cryo-electron microscopy (cryo-EM) is rapidly becoming an attractive method in the field of structural biology. With the exploding popularity of cryo-EM, sample preparation must evolve to prevent congestion in the workflow. The dire need for improved microscopy samples has led to a diversification...
