The aim of this study is to establish large tissue sections for 10 kinds of tumors. in order to observe the tumor landscape on microscope. The tumors including esophageal carcinoma,gastric carcinoma,hepatocellular carcinoma etc.200 cases of each tumor will be compared by traditional sample method and landscape sample method to testify the clinical value and significance of tumor landscape pathological diagnosis .

In Alzheimer's disease (AD), neurofibrillary degeneration (NFD) is characterized by the intraneuronal aggregation of Tau proteins. The pathology progresses through a hierarchical pathway t...
There is an established consensus between researchers that the contact with natural environments has beneficial influence on mental health and well-being of people exposed to them. The kno...
The assessment of the refractive state of the eye is a fundamental and important part of ophthalmic and optometric clinical practice. The development of an unsupervised online subjective r...
As a δ N-NO analysis method, the acetone method that was recently reported comprises a straightforward sample preparation process. However, the applicability of the method to water samples with high ...

Traditionally, for a liquid chromatography tandem mass spectrometry (LC-MS/MS) bioanalytical assay, an external calibration curve is required to achieve accurate quantitation of an analyte. Recently, ...
A solventless sample preparation method, invented in 1989, that uses a fused silica fiber which is coated with a stationary phase. It is used for sample cleanup before using other analytical methods.
A method of detection of the number of cells in a sample secreting a specific molecule. Wtih this method a population of cells are plated over top of the immunosorbent substrate that captures the secreted molecules.
A method of simultaneously imaging and measuring elements at the submicron level. Nuclear microscopy uses a focused high-energy ion beam of PROTONS and ALPHA PARTICLES (a nuclear microprobe) to interact with the sample. The resulting emitted radiations are analyzed by a group of techniques simultaneously: PARTICLE INDUCED X RAY EMISSION SPECTROMETRY for minor and trace element identification; Rutherford Backscattering Spectroscopy to assess sample thickness and bulk elements such as carbon, hydrogen, oxygen, and nitrogen; and Scanning Transmission Ion Microscopy to assess sample structure and density.
The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.
The application of pathology to questions of law.
