Record-breaking bifunctional oxygen electrocatalyst accomplished by a data-driven approach for zinc-air batteries

引用

Journal of Energy Chemistry 2025年第1期100卷 144-145页

作者： Deviprasath Chinnadurai Zhi Wei Seh Institute of Materials research and Engineering (IMRE) Agency for Science Technology and Research (A*STAR)

Rechargeable zinc-air batteries(ZABs) have recently drawn great attention in energy research due to their high theoretical capacity,low costs, and inherently safe nature [1–3]. However, the sluggish cathode reactions necessitate the development of bifunctional oxygen electrocatalysts with lower ΔE indicator values. The ΔE indicator is commonly employed to quantitatively evaluate the electrocatalytic activity of a bifunctional oxygen electrocatalyst,representing the overall overpotential from oxygen reduction reaction(ORR) to oxygen evolution reaction(OER).

Therapeutic potential of exercise-hormone irisin in Alzheimer's disease

Neural Regeneration research 2025年第6期20卷 1555-1564页

作者： Eunhee Kim Rudolph ETanzi Se Hoon Choi Genetics and Aging research unit MassGeneral Institute for Neurodegenerative DiseaseDepartment of NeurologyMassachusetts General HospitalHarvard Medical SchoolCharlestownMAUSA McCance Center for Brain Health Massachusetts General HospitalBostonMAUSA

Irisin is a myokine that is generated by cleavage of the membrane protein fibronectin type Ⅲ domain-containing protein 5(FNDC5) in response to physical exercise. Studies reveal that irisin/FNDC5 has neuroprotective functions against Alzheimer's disease, the most common form of dementia in the elderly, by improving cognitive function and reducing amyloid-β and tau pathologies as well as neuroinflammation in cell culture or animal models of Alzheimer's disease. Although current and ongoing studies on irisin/FNDC5 show promising results, further mechanistic studies are required to clarify its potential as a meaningful therapeutic target for alleviating Alzheimer's disease. We recently found that irisin treatment reduces amyloid-β pathology by increasing the activity/levels of amyloid-β-degrading enzyme neprilysin secreted from astrocytes. Herein, we present an overview of irisin/FNDC5's protective roles and mechanisms against Alzheimer's disease.

An efficient molecular method for the accurate and efficient identification of indica and japonica rice was created based on the poly-morphisms of insertion/deletion(InDel) DNA fragments obtained from the basic local alignment search tool(BLAST) to the entire genomic sequences of indica(93-11) and japonica rice(Nipponbare).The 45 InDel loci were validated experimentally by the polymerase chain reaction(PCR) and polyacrylamide gel electrophoresis(PAGE) in 44 typical indica and japonica rice varieties,including 93-11 and Nipponbare.A neutrality test of the data matrix generated from electrophoretic banding patterns of various InDel loci indicated that 34 InDel loci were strongly associated with the differentiation of indica and japonica *** extensive analyses involving cultivated rice varieties from 11 Asian countries,and 12 wild Oryza species with various origins confirmed that indica and japonica characteristics could accurately be determined via calculating the average frequency of indica-or japonica-specific alleles on different InDel loci across the rice *** method was named as the ’’InDel molecular index" that combines molecular and statistical methods in determining the indica and japonica characteristics of rice *** with the traditional methods based essentially on morphology,the InDel molecular index provides a very accurate,rapid,simple,and efficient method for identifying indica and japonica *** addition,the InDel index can be used to determine indica or japonica characteristics of wild Oryza species,which largely extends the utility of this *** InDel molecular index provides a new tool for the effective selection of appropriate indica or japonica rice germplasm in rice *** also offers a novel model for the study of the origin,evolution,and genetic differentiation of indica and japonica rice adapted to various environmental changes.

Past climate and vegetation in Southeast Bulgaria——a study based on the late Miocene pollen record from the Tundzha Basin

引用

Journal of Palaeogeography 2019年第1期8卷 43-67页

作者： Dimiter Ivanov Maria Lazarova Institute of biodiversity and Ecosystem research Bulgarian Academy of Sciences

The results of palynological studies on the late Miocene freshwater deposits of the Tundzha Basin(Southeast Bulgaria, SE Europe) are presented. The basin is relatively well known in terms of geology and *** age of sediments in the Tundzha Basin ranges between the late Miocene to the Pliocene, based on mammal and diatom fossils. We carried out a palynological analysis of clayey sediments interlayered with coal beds from four cores and from one outcrop, aiming to obtain information about the composition and the structure of fossil vegetation. The ratios between the main floristic elements and the composition of the fossil flora are analysed and discussed from a palaeoecological point of view. Several main vegetation palaeocommunities were recorded:swamp forests, mixed mesophytic, communities of aquatic plants, and herbaceous palaeocoenoses. The changes in vegetation and in plant diversity are identified. The palaeoclimate analysis indicates a warm temperature climate with high rainfall and mild winter temperatures, without seasonal drier conditions. The early Pontian climate was about 3–4 ℃ warmer than today, with rainfalls per year at least 300 mm higher than today. The results of palaeoecological analysis of the flora and of the quantitative palaeoclimate data show that the climate in the Southeast Bulgaria indicates a climate change towards slight cooling and some drying. This event is consistent with the period of accumulation of the upper, undivided part of the Elhovo Formation.
