Fertilisation of the Pansy [PDF]

open access: yesNature, 1873
I AM glad to be able to confirm, to-some extent, from observation, Mr. Bennett's theory of the fertilisation of the Pansy, given in NATURE, vol. viii. p. 49. I watched a considerable number of specimens of Viola tricolor on a grassy hill-top where the smaller insects were very numerous and busy, and twice saw them entered by a minute fly.

The influence of plant fertilisation regime on plant-aphid-parasitoid interactions [PDF]

open access: yes, 2003
This thesis examines effects of plant fertilisation regime on herbivore and parasitoid performance for two aphids, Macrosiphum euphorbiae and Myzus persicae, and one parasitoid wasp, Aphidius ervi. Herbivore performance was measured as adult fresh weight

Establishment and optimization of the two‐step induction system for generating primordial germ cell‐like cells from chicken embryonic stem cells

open access: yesFEBS Open Bio, EarlyView.
This study optimizes a two‐step induction system to generate PGCLCs from chicken ESCs. The induced cells express germline markers and migrate to gonads in ovo, offering a novel approach for avian genetic resource conservation. Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs.

Fertilisation of the Speedwell [PDF]

open access: yesNature, 1882
IF Mr. Stapley, who wrote on this subject in last week's NATURE, can refer to Dr. H. Muller's treatise on the relations between flowers and insects, in the first volume of Shenk's Handbuch der Botanik (now publishing as part of Trewendt's Encyclopaedie der Naturwissenschaften), he will see that his own observations are very similar to those of Dr ...

LIN28B Promotes Cancer Cell Dissemination and Angiogenesis

open access: yesAdvanced Biology, EarlyView.
Children diagnosed with high‐risk neuroblastoma have a 5‐year event‐free survival rate of less than 50% and poor outcomes after recurrence. Deregulation of the LIN28B oncogene can be addressed in these patients. Upregulation of LIN28B is shown to support the metastatic cascade.

Controlling broad-leaved dock (Rumex obtusifolius) in grass clover mixtures [PDF]

open access: yes, 2006
This article describes three experiments on the control of broad-leaved dock. Experiment 1: Dock seeds were ensiled in grass silages of different dry matter percentages; 23, 34 and 60% respectively.

Detecting Dengue in Flight: Leveraging Machine Learning to Analyze Mosquito Flight Patterns for Infection Detection

open access: yesAdvanced Biology, EarlyView.
Dengue infection alters mosquito flight behavior, enabling detection using machine learning classifiers. This study analyzes 3D flight trajectories and evaluates multiple models, showing that longer sequence lengths improve classification performance.

Plasma‐Treated Hydrogel for Combined RONS and Chemotherapy Delivery: A Proof‐of‐Concept In Ovo

open access: yesAdvanced Functional Materials, EarlyView.
This study explores plasma‐treated hydrogels (PTH) as a new way to deliver both reactive oxygen and nitrogen species and chemotherapy (Doxorubicin) directly to tumors. In ovo tests show effects after a single dose, especially in osteosarcoma tumors. Tumor weight decrease, and a resistance‐related protein is reduced.

Optimisation de la fertilisation azotée de cultures industrielles légumières sous irrigation [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2010
Optimisation of fertilisation for irrigated vegetables. Experiments were performed over four years, testing five cultivations to optimise mineral nitrogen fertilisation when irrigation with wastewater occurs.
