AI Article Synopsis
- The study aimed to investigate the inorganic elements in the plant Polygonum multiflorum by measuring various elements using ICP-AEC.
- Wild specimens of P. multiflorum were found to have significantly higher levels of certain elements (Al, Ca, K, Mg, Sr, Ti) compared to cultivated ones, while other elements showed no significant differences.
- Principal component analysis (PCA) revealed that Al, B, Ba, Fe, Na, Ni, Ti, Ca, and Sr are characteristic elements of P. multiflorum, with a notable variation in element distribution from samples taken in Tianyang.
Article Abstract
Objective: To explore the character of inorganic elements in Polygonum multiflorum.
Method: The contents of elements such as Al, B, Ba, Ca, Cu, Mn, Mg, Fe, Na, Ni, P, Se, Sr, Ti and Zn in nine P. multiflorum samples were determined by means of ICP-AEC. The results were used for the development of element distrubution diagram. The principal component analysis and one-way ANOVA of SPSS were applied for the study of characteristic elements in P. multiflorum.
Result: The contents of Al, Ca, K, Mg, Sr,Ti in wild P. multiflorum were remarkable higher than those in cultured P. multiflorum, and there was no significant difference between cultured and wild in the other elements. Five principal components which accounted for over 90% of the total variance were extracted from the original data. The analysis results show that Al, B, Ba, Fe, Na, Ni, Ti, Ca and Sr may be the characteristic elements in P. multiflorum. The element distrubution diagram of the sample from Tianyang was remarkable different comparing with the others.
Conclusion: The principal component analysis could be used in data processing in inorganic elements.

This research examined the distinction between organic and conventional mango fruits, chips, and juice using portable near-infrared (NIR) spectroscopy. A comprehensive analysis was conducted on a sample of 100 mangoes (comprising 50 organic and 50 conventional) utilising a portable NIR spectrometer that spans a wavelength range from 900 to 1700 nm. The mangoes were assessed in their entirety and their juice and chip forms.

The substantia nigra pars compacta (SNc), one of the main dopaminergic nuclei of the brain, exerts a regulatory function on the basal ganglia circuitry via the nigro-striatal pathway but its possible dopaminergic innervation of the thalamus has been only investigated in non-human primates. The impossibility of tract-tracing studies in humans has boosted advanced MRI techniques and multi-shell high-angular resolution diffusion MRI (MS-HARDI) has promised to shed more light on the structural connectivity of subcortical structures. Here, we estimated the possible dopaminergic innervation of the human thalamus via an MS-HARDI tractography of the SNc in healthy human young adults.

Background And Aims: Torminalis glaberrima (Gand.) Sennikov & Kurtto is a European tree species currently underutilized in forestry, valued for its high-quality wood and contribution to ecosystem stability. Despite a projected range expansion as climate change progresses, current population fragmentation levels may inhibit the species' ability to migrate and stabilize fragile forest ecosystems.

"Rui Yang", "Rui Xue", and "Rui Xiang Hong" are newly cultivated apple varieties with excellent flavor. However, the key aroma-active compounds responsible for its excellent flavor quality were unclear. This study determined the characteristics of aroma compounds among three new apple varieties and their parental species by Sensomics.

Background: Differences in social behaviours are common in young people with neurodevelopmental conditions (NDCs). Recent research challenges the long-standing hypothesis that difficulties in social cognition explain social behaviour differences.
Aims: We examined how difficulties regulating one's behaviour, emotions and thoughts to adapt to environmental demands (i.
