Fecal microbiota transplantation as a new way for OVA-induced atopic dermatitis of juvenile mice.

Children all over the world suffer from atopic dermatitis (AD), a prevalent condition that impairs their health. Corticosteroids, which have long-term negative effects, are frequently used to treat AD. There has been a growing body of research on the gut microbiota's function in AD.

[Feasibility of using NIR spectroscopy to detect melamine in milk].

In the present study, 22 certified milk samples without melamine were collected, then 50 adulterated milk samples with added different content of melamine (0.1-1 500 mg x kg(-1)) were prepared. The near-infrared (NIR) spectra of these milk samples were measured.

[Determination of soil quality from Chinese apple plant area by NIR spectroscopy].

In the present work, 111 soil samples from 11 different Chinese apple plant areas were used to take the diffuse reflection spectra from 12 500 to 4 000 cm(-1) by FT-NIR. The models of organic substance and pH value of soil samples were built by using partial least square regression (PLSR). The calibration model gave the correlation coefficients of 0.

A prediction model of occupational manganese exposure based on artificial neural network.

Application of two statistical models to reconstruct occupational exposure to manganese (Mn) is discussed. Air monitoring of 635 samples were analyzed by a back-propagation artificial neural network (back-propagation ANN) in comparison with a multiple linear regression (MLR). The stepwise MLR yielded significant results with five selected variables for predicting airborne manganese dioxide (MnO(2)).

[The functional mechanism between the pesticide Pyrimorph and humic acid].

In the present experiment, we mainly discussed the function mechanism between the humic acid and a new kind of fungicide Pyrimorph, aiming to play a positive role in the reduction of contamination caused by pesticides on environment. After the disposition step by step, the humic acid was separated into three parts. Then IR and fluorescence analytical methods were employed to explain the functional mechanism between the pesticide and each part of humic acid.
