The homology of a lattice

Discrete Mathematics, 1971
AbstractWith each bounded lattice L is associated a simplicial complex KL. If X is a cross-cut of L, then a simplicial complex KX is defined. It is shown that the geometric realizations of KX and KL are homotopy equivalent.

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

FEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Vajrayāna Art and Iconography

Zygon, 2000
Iconographic imagery in the Indo‐Tibetan Buddhist Tantric (i.e., Vajrayāna) tradition is replete with polymorphic symbolic forms. Tantric texts themselves are multivalent, addressing astronomy, astrology, cosmology, history, embryology, physiology ...

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

FEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

Ecomorphology and history of a recurrent evolutionary adaptation to long-distance bird dispersal in Asteraceae

Boletín de la Sociedad Argentina de Botánica
Background and aims: Genera of Asteraceae, belonging to different tribes, present a repeated pattern of morphological adaptations to epiornithochory and have unique distributions (widely disjunct and/or inhabit remote islands). This pattern requires the

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

A general theory of the complex pronotum morphology of treehoppers in Smiliinae and its relatives (Hemiptera: Membracidae) and its applicability to other subfamilies

European Journal of Entomology
Treehoppers are characterized by exaggerated and three-dimensionally modified pronotal structures, known as "helmets". The treehopper pronotum has been studied mainly in terms of taxonomic diagnosis for over a century.

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

FEBS Open Bio, EarlyView.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.
