Lithium Diisopropylamide‐Mediated Ring‐Opening of Tetrahydrofuran in the Synthesis of Polyhydroxylated Indolizidines

European Journal of Organic Chemistry, EarlyView.
Chiral tri‐ and pentahydroxy spirocyclopentane‐indolizidines were synthesized using lithium diisopropylamide “LDA” promoted diallylation and tetrahydrofuran “THF” ring‐opening in a one‐pot procedure as a key step. The sequence leading to the targeted hydroxy‐spiroindolizidines was achieved by cis‐dihydroxylation followed by reduction of the enamine and

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

Geological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Appraisal of international, patient‐facing resources on heavy menstrual bleeding

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract This study aimed to systematically evaluate the quality of widely accessible, English language, patient‐facing resources on heavy menstrual bleeding (HMB), identifying strengths, gaps, and opportunities for improvement. Resources were obtained from (1) a systematic Google Trends‐informed Google search and (2) submissions from subject matter ...

Solving bi-directional soliton equations in the KP hierarchy by gauge transformation [PDF]

, 2006
We present a systematic way to construct solutions of the (n = 5)-reduction of the BKP and CKP hierarchies from the general τ function τn+k of the KP hierarchy.

Host‐specific and deterministic microbiome assembly in major coleopteran stored‐grain pests

iMetaOmics, EarlyView.
Dual DNA‐ and RNA‐based sequencing profiled the microbiomes of five major coleopteran stored‐grain pests and their wheat flour substrate. The microbiomes differed significantly among hosts and from flour, yet 11 core bacterial and 9 core fungal taxa were shared across hosts. RNA data revealed host‐specific active microbiota.

The Relation Between Two Types of Frequent Wave Breaking Over Southeastern Siberia and Different Conditions of Unseasonable Midsummer Weather Over Japan

International Journal of Climatology, EarlyView.
To analyze the different morphologies of Rossby wave breaking over Eastern Siberia and their relationships with the anomalous patterns of temperature and precipitation that cause unseasonable midsummer weather conditions over Japan, we performed regression analyses against the interannual variabilities of the anticyclonic and cyclonic Rossby wave ...

Shaping Entrepreneurial Intentions Through Education: The Role of the University's Entrepreneurial Mission and Strategic Change

Strategic Change, EarlyView.
ABSTRACT This study examines the impact of students' attitudes toward entrepreneurship education (ATEE) on their entrepreneurial intentions (EI) and whether this relationship is moderated by the university's entrepreneurial mission (UEM). Based on the Strategic Change Theory, the university's mission is presented as a strategic instrument through which

Small‐Molecule Kinase Inhibitors Modulating Circadian Rhythms

Medicinal Research Reviews, EarlyView.
ABSTRACT The circadian clock mechanism generates 24‐h rhythms crucial for regulating various physiological processes, and its dysregulation has been implicated in numerous diseases. In cells, the circadian clock operates through a transcriptional‐translational feedback loop, where phosphorylation plays a pivotal role in maintaining accurate circadian ...

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

PLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.
