Larval Development of the European Lobster and How Small Heterochronic Shifts Lead to a More Pronounced Metamorphosis

open access: yesInternational Journal of Zoology, 2015
We redescribe the larval stages of the European lobster, Homarus gammarus, based on autofluorescence composite imaging. We focus on larval stages (II) to (IV).

Larval morphology and life history of Eutrichosoma mirabile Ashmead and description of a new species of Eutrichosoma (Hymenoptera, Chalcidoidea) [PDF]

open access: yesJournal of Hymenoptera Research, 2020
The larval morphology and life history of the weevil parasitoid Eutrichosoma mirabile Ashmead (Hymenoptera, Chalcidoidea, Pteromalidae) are described, and the phylogenetic placement of the subfamily Eutrichosomatinae within Chalcidoidea is determined ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Gonad variation and development of freshwater mussel Chambardia rubens Lamarck, 1819 (Bivalvia: Mutelidae) from the River Nile in Egypt [PDF]

open access: yesJournal of Bioscience and Applied Research, 2018
The gametogenesis, reproductive cycle, and larval morphology of Chambardia rubens (Bivalvia: Mutelidae) are studied for the first time in Egypt. A total of 46 mussels were collected seasonally from winter to autumn 2017 from Benha (Qaluobiya Governorate)

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Description of immature stages of Cephitinea colonella (Erschoff, 1874) (Lepidoptera: Tineidae: Myrmecozelinae)

open access: yesJournal of Asia-Pacific Biodiversity, 2023
Cephitinea colonella (Erschoff, 1874) (Lepidoptera: Tineidae: Myrmecozelinae) is known as a pest of stored products. However, detailed information on its life history is poor.

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

open access: yesFEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Ontogenesis and functional morphology of the digestive system of the freshwater prawn, Macrobrachium amazonicum (Decapoda: Palaemonidae)

open access: yesZoologia (Curitiba), 2011
The appropriate feeding regime for larvae and post-larvae of crustacean decapods is essential for successful larval culture. Reports on the development and morphology of the mouthparts and foregut of these crustaceans have aided in the selection of ...

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

open access: yesFEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Chondrocranial and hyobranchial structure in two South American suctorial tadpoles of the genus Telmatobufo (Anura: Calyptocephalellidae)

open access: yesPhyllomedusa: Journal of Herpetology, 2020
Chondrocranial and hyobranchial structure in two South American suctorial tadpoles of the genus Telmatobufo (Anura: Calyptocephalellidae). The chondrocranium, hyobranchium, rectus abdominis muscle, and epaxial musculature of Telmatobufo australis and T ...
