Measuring Molecular Forces With Atomic Force Microscopy 1: Solvent Influence on Hydrophobic Interactions

open access: yesMicroscopy Research and Technique, EarlyView.
Atomic force microscopy enables precise evaluation of the magnitude and range of hydrophobic and van der Waals interactions. This primer presents a protocol for fluorocarbon functionalization of gold surfaces and examines how water: DMSO mixtures affect hydrophobic forces, with data interpreted through an extended van der Waals model.

Comparative Aspects of Structure and Function of Cnidarian Neuropeptides

open access: yesFrontiers in Endocrinology, 2020
Cnidarians are early-branching animals in the eukaryotic tree of life. The phylum Cnidaria are divided into five classes: Scyphozoa (true jellyfish), Cubozoa (box jellyfish), Hydrozoa (species, Hydra and Hydractinia), Anthozoa (sea anemone, corals, and ...

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Diurnal and circadian regulation of opsin-like transcripts in the eyeless cnidarian Hydra

open access: yesBiomolecular Concepts
Opsins play a key role in the ability to sense light both in image-forming vision and in non-visual photoreception (NVP). These modalities, in most animal phyla, share the photoreceptor protein: an opsin-based protein binding a light-sensitive ...

Tentacle morphogenesis in hydra [PDF]

open access: yes, 1990
Stimulation of tentacle-specific cell differentiation by the neuropeptide head activator was investigated in Hydra magnipapillata. Tentacle-specific sensory nerve cells were identified by a monoclonal antibody, NV1.

Mini-Collagens in Hydra Nematocytes [PDF]

open access: yes, 1991
We have isolated and characterized four collagen-related c-DNA clones (N-COL 1, N-COL 2, N-COL 3, N-COL 4) that are highly expressed in developing nematocytes in hydra.

Traditional Chinese Medicine as an Integrative Adjunct in Oncology Perioperative Practice: Analgesia, Immune Modulation, and Translational Challenges

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT Traditional Chinese medicine (TCM), including herbal analgesic adjuvants and acupuncture‐based interventions, has gained increasing attention as an integrative strategy for perioperative pain management in oncology. Bioactive phytochemicals—such as terpenoids, flavonoids, alkaloids, and polyphenols—exert multimodal pharmacological effects ...

The properties of nerve cell precursors in hydra [PDF]

open access: yes, 1986
Two signals, the head activator and an injury stimulus, control differentiation of nerve cells from uncommitted stem cells in hydra [Th. Holstein, H. C. Schaller, and C. N. David, (1986) Dev. Biol. 115, 9–17].

Navigating the Rapids: How Non‐Governmental Organization Managers Develop Strategic Adaptation to Repressive Political Environments

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT This article explores the management adaptation strategies non‐governmental organizations (NGOs) managers employ in order to operate in repressive political environments. It answers the question: how do NGO managers initiate, manage and sustain internal change when the political/regulatory environment changes?
