Control of social monogamy through aggression in a hermaphroditic shrimp

open access: yesFrontiers in Zoology, 2011
Introduction Sex allocation theory predicts that in small mating groups simultaneous hermaphroditism is the optimal form of gender expression. Under these conditions, male allocation is predicted to be very low and overall per-capita reproductive output ...

Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Life in two dimensions or keeping your head down: Lateral exuvial splits in leaf-mining larvae of Pachyschelus (Coleoptera: Buprestidae) and Cameraria (Lepidoptera: Gracillariidae)

open access: yesEuropean Journal of Entomology, 2013
This paper describes previously unreported lateral cuticle splits occurring during the moulting of larvae of the leaf-miners Pachyschelus laevigatus (Say, 1839) (Coleoptera: Buprestidae) and Cameraria sp. (Lepidoptera: Gracillariidae).

Ophidiomycosis Prevalence and Disease Ecology in a Natrix tessellata (Laurenti, 1768) Population From Northern Italy

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Fungal pathogens pose a growing threat to vertebrate biodiversity. In snakes, Ophidiomyces ophidiicola (Oo) has garnered particular concern, although its impact in Europe remains poorly understood. We conducted a season‐long, standardized survey of dice snakes (Natrix tessellata) along the northern shore of Lake Como (Italy) to quantify Oo and

Cost‐effectiveness and long‐term outcomes of periodontal regeneration versus dental implants: A retrospective study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Direct comparative data on periodontal regeneration (PR) versus extraction and implant placement remain limited. Tooth‐specific periodontal conditions such as furcation involvement and overall tooth prognosis may dictate success or failure of such treatment.

Factorization and Resummation for Groomed Multi-Prong Jet Shapes

open access: yes, 2017
Observables which distinguish boosted topologies from QCD jets are playing an increasingly important role at the Large Hadron Collider (LHC). These observables are often used in conjunction with jet grooming algorithms, which reduce contamination from ...

Evaluation of Discoidin domain receptor 1 (DDR1) in junctional epithelial permeability and wound healing

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Epithelium is the periodontal first line of defense against microbes. Discoidin domain receptor 1 (DDR1) is a collagen receptor expressed in epithelium. Ddr1 knockout (Ddr1−/−) mice develop periodontitis‐like defects, including junctional epithelium (JE) downgrowth, bacterial invasion, and alveolar bone loss.

Transcriptomic analysis of crustacean neuropeptide signaling during the moult cycle in the green shore crab, Carcinus maenas

open access: yesBMC Genomics, 2018
Background Ecdysis is an innate behaviour programme by which all arthropods moult their exoskeletons. The complex suite of interacting neuropeptides that orchestrate ecdysis is well studied in insects, but details of the crustacean ecdysis cassette are ...

Approach to Nail Pitting in Pediatric and Adolescent Patients: A Dermatology Perspective

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT This narrative review aims to discuss the etiologies of nail pitting in pediatric and adolescent patients, while providing a framework for further evaluation of possible underlying systemic conditions and their clinical findings from a dermatologic standpoint.
