With increasing age,humans become more susceptible to the onset of neurodegenerative diseases(NDs),and among these,Alzheimer's disease(AD)is the most frequent(Nicoletti et al.,2023).NDs are primarily characterized by neuronal loss and atrophy,but also by lesions involving the cerebral and/or cardiovascular system(Balistreri,2021).Lesions such as macroinfa rcts,microinfarcts,hemorrhages,white matter lesions,atherosclerosis,and arteriolosclerosis have also been significantly described in the preclinical stages of cognitive impairment characterizing NDs(Mariani et al.,2007).

MicroRNAs as potential diagnostic biomarkers for bipolar disorder

Neural Regeneration Research 2025年第6期20卷 1681-1695页

作者： Bridget martinez Philip V.Peplow Department of Pharmacology University of Nevada-RenoRenoNVUSA Department of Medicine University of Nevada-RenoRenoNVUSA Department of Anatomy University of OtagoDunedinNew Zealand

Abnormal expression of microRNAs is connected to brain development and disease and could provide novel biomarkers for the diagnosis and prognosis of bipolar disorder. We performed a PubMed search for microRNA biomarkers in bipolar disorder and found 18 original research articles on studies performed with human patients and published from January 2011 to June 2023. These studies included microRNA profiling in bloodand brain-based materials. From the studies that had validated the preliminary findings,potential candidate biomarkers for bipolar disorder in adults could be miR-140-3p,-30d-5p,-330-5p,-378a-5p,-21-3p,-330-3p,-345-5p in whole blood, miR-19b-3p,-1180-3p,-125a-5p, let-7e-5p in blood plasma, and miR-7-5p,-23b-5p,-142-3p,-221-5p,-370-3p in the blood serum. Two of the studies had investigated the changes in microRNA expression of patients with bipolar disorder receiving treatment. One showed a significant increase in plasma miR-134 compared to baseline after 4 weeks of treatment which included typical antipsychotics, atypical antipsychotics, and benzodiazepines. The other study had assessed the effects of prescribed medications which included neurotransmitter receptorsite binders(drug class B) and sedatives, hypnotics, anticonvulsants, and analgesics(drug class C) on microRNA results. The combined effects of the two drug classes increased the significance of the results for miR-219 and-29c with miR-30e-3p and-526b* acquiring significance. MicroRNAs were tested to see if they could serve as biomarkers of bipolar disorder at different clinical states of mania, depression, and euthymia. One study showed that upregulation in whole blood of miR-9-5p,-29a-3p,-106a-5p,-106b-5p,-107,-125a-3p,-125b-5p and of miR-107,-125a-3p occurred in manic and euthymic patients compared to controls, respectively, and that upregulation of miR-106a-5p,-107 was found for manic compared to euthymic patients. In two other studies using blood plasma,downregulation of miR-134 was observed i

Autism spectrum disorder:difficulties in diagnosis and microRNA biomarkers

Solid State Reactions in Cr<sub>2</sub>O<sub>3</sub>-ZnO Nanoparticles Synthesized by Triethanolamine Chemical Precipitation

引用

Materials Sciences and Applications 2011年第11期2卷 1584-1592页

作者： Imelda Esparza Myriam Paredes roberto martinez Adriana Gaona-Couto Guadalupe Sanchez-Loredo Luisa M. Flores-Velez Octavio Dominguez 不详

The present work reports the preliminary results about solid state reactions of Cr-ZnO solid solutions and ZnCr2O4 nanometric particles obtained with triethanolamine (TEA). Different compositions were prepared from 0.65 to 33.3 at % chromium, the last one corresponding to ZnCr2O4 cubic spinel composition. Fourier Transform Infrared Spectroscopy (FTIR) together with X-ray diffraction (XRD) patterns of powders with Cr3+ between 0.65 and 16.0 at % were assigned to Cr-ZnO solid solution due to the only presence of ZnO structure, FTIR spectra indicating that Cr-O bonding exists even if there was no presence of ZnCr2O4. With low chromium atomic percent, lattice parameters increase, but as the chromium content exceeds of 3 at %, there is basically no further expansion of the cell. From Williamson-Hall and Rietveld methods the lattice dimensions were assigned to chromium incorporation in ZnO structure and the lattice contraction by particle size refinement. After annealing all samples from 0.65 to 16.0 at % at 400°C in oxygen, the analysis showed that nanoparticles of Cr-ZnO solid solution still remain.
