Pollination and seedling ecology of Decalepis hamiltonii Wight & Arn. (Periplocaceae), a commercially important, endemic and endangered species

Journal of Threatened Taxa, 2009
Decalepis hamiltonii is a woody climber and annual bloomer. The flowers are characterized by nectariferous coralline corona, gynostegium and pollinia containing tetrads. The floral features such as greenish white corolla, mild fragrance, flat-shape for

Animal‐mediated seed dispersal: A review of study methods

Applications in Plant Sciences, EarlyView.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

Phenotypic Selection in Halenia elliptica D. Don (Gentianaceae), an Alpine Biennial with Mixed Mating System

Plants, 2022
The transition from outcrossing to selfing is a common evolutionary trend in flowering plants, and floral traits change significantly with the evolution of selfing.

Mucosal‐Associated Invariant T Cells in Rheumatic Diseases

Arthritis &Rheumatology, EarlyView.
Mucosal‐associated invariant T (MAIT) cells are innate‐like T cells defined by their semi‐invariant T cell receptor and restriction by the major histocompatibility complex class I–related molecule (MR1). These cells are primarily activated by microbial‐derived metabolites presented by MR1 or by cytokines.

New genomic resources and comparative analyses reveal differences in floral gene expression in selfing and outcrossing Collinsia sister species

G3: Genes, Genomes, Genetics, 2021
The evolutionary transition from outcross- to self-fertilization is one of the most common in angiosperms and is often associated with a parallel shift in floral morphological and developmental traits, such as reduced flower size and pollen to ovule ...

Clinical Significance of Gut Microbiota Community Types for Long‐Term Response to Fecal Microbiota Transplantation in Patients With Psoriatic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Fecal microbiota transplantation (FMT) holds promises as a beneficial supplement to methotrexate in patients with psoriatic arthritis (PsA). We therefore investigated how gut bacterial signatures in patients and donor strain engraftment were associated with long‐term response to FMT.

Cannabinoids and drug–drug pharmacokinetic interactions: Deciphering the risks

British Journal of Clinical Pharmacology, EarlyView.
The relationship between cannabinoids and mental health has become a major focus of scientific inquiry and public discourse. Cannabinoids are diverse chemical compounds from the Cannabis species that have been explored for their therapeutic applications in treating chronic pain, psychiatric and neurological conditions, such as depression, schizophrenia,
