The Rickettsial Ankyrin Repeat Protein 2 Is a Type IV Secreted Effector That Associates with the Endoplasmic Reticulum

open access: yesmBio, 2018
Strains of Rickettsia rickettsii, the tick-borne agent of Rocky Mountain spotted fever, vary considerably in virulence. Genomic comparisons of R. rickettsii strains have identified a relatively small number of genes divergent in an avirulent strain ...

Microbiological, parasitic, microscopic, physical and chemical characterization of processed acai (Euterpe oleracea Mart.) fruits

open access: yesActa Veterinaria Brasilica, 2017
Acai (Euterpe oleracea Mart.) fruit consumption has been increasing in recent years. The increasing demand for this fruit increased concerns about its quality. Thus, the objective of this work was to assess the microbiological, parasitical, microscopic, physical and chemical characteristics of processed acai.

Development of a loop‐mediated isothermal amplification‐lateral flow dipstick (LAMP‐LFD) assay and on‐site rapid detection evaluation for Rodentibacter heylii and Rodentibacter pneumotropicus

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study established a closed‐tube LAMP‐LFD assay for detecting Rodentibacter heylii and Rodentibacter pneumotropicus. The method exhibited high sensitivity (detection limits of 10−5 ng/μL for R. heylii and 10−4 ng/μL for R. pneumotropicus), high specificity, reliable performance with clinical samples, and effective validation in experimental ...

Beyond wound sealing: A dual‐functional adhesive nanofiber membrane promoting coagulation and osteogenesis in extraction sites

open access: yesBMEMat, EarlyView.
Inspired by the suction mechanics of octopus suckers, a dual‐layer nanofiber membrane integrates antibacterial protection, strong wet adhesion, and osteogenic support, offering a bioinspired strategy for effective hemostasis and alveolar bone preservation.

Advanced nanotherapeutics for combating ocular infections: Rational design, antimicrobial mechanisms, and therapeutic breakthroughs

open access: yesBMEMat, EarlyView.
Nanomaterials revolutionize ocular infection treatment by enabling targeted drug delivery and enhanced antimicrobial efficacy against resistant pathogens. This review systematically explores their rational design, multimodal mechanisms, and translational potential for next‐generation anti‐infective therapies.

Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

open access: yesBiological Reviews, EarlyView.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Flight of the dragons: a global review of migration in Odonata

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

Comparative development of human filariae Loa loa, Onchocerca volvulus and Mansonella perstans in immunocompromised mouse strains

open access: yesFrontiers in Tropical Diseases
IntroductionMouse models of human filarial infections are not only urgently needed to investigate the biology of the nematodes and their modulation of the host’s immunity, but will also provide a platform to screen and test novel anti-filarial drugs ...

The costs of extra‐pair behaviours in birds

open access: yesBiological Reviews, EarlyView.
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.
