Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

Journal of Surfactants and Detergents, EarlyView.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

Direct and indirect effects of Gracilaria vermiculophylla on native Fucus vesiculosus [PDF]

, 2013
The perennial red macroalga Gracilaria vermiculophylla (Ohmi) Papenfuss has recently been introduced to the Baltic Sea and is a potential competitor to Fucus vesiculosus, the most common native perennial alga in large parts of the Baltic Sea.

Metabolic reprogramming of periwinkle plant culture [PDF]

Nature Chemical Biology, 2009
We transformed an alkaloid biosynthetic gene with reengineered substrate specificity into Catharanthus roseus. The resulting transgenic plant cell culture produced a variety of unnatural alkaloid compounds when cocultured with simple, achiral, commercially available precursors that the reengineered enzyme was designed to accept.

Kaposiform hemangioendothelioma: Diagnosis and treatment

Pediatric Investigation, EarlyView.
Vascular endothelial growth factor‐C (VEGF‐C)/vascular endothelial growth factor receptor‐3 (VEGFR‐3) and angiopoietin‐2 (Ang‐2)/tyrosine kinase with immunoglobulin‐like and EGF‐like domain 2 (TIE2) signaling pathways play an important role in lymphangiogenesis.

Beet leafhopper transmits virescence of periwinkle

California Agriculture, 1977
Photo above shows healthy periwinkle on left and virescence-affected periwinkle on right; plant on right was exposed to beet leafhopper (Circulifer tenellus) that had previously fed on another virescence-affected periwinkle.

Tympanotonus fuscatus - its potential and abundance in the mangrove swamps of the upper Bonny River, River State [PDF]

, 2005
The Shellfish Tympanotonus fuscatus fisheries was studied in the upper Bonny River of River State. Abundance and size distribution were evaluated through collection of the Shellfish from 4 sampling stations along the River System.

'Candidatus Phytoplasma malaysianum', a novel taxon associated with virescence and phyllody of Madagascar periwinkle (Catharanthus roseus). [PDF]

, 2013
This study addressed the taxonomic position and group classification of a phytoplasma responsible for virescence and phyllody symptoms in naturally diseased Madagascar periwinkle plants in western Malaysia.

Transcriptional Regulation of the Novel Theacrine Synthase Gene CsTcS2 by the CsTINY–CsWRKY33 Module Underpins Theacrine Biosynthesis in Camellia sinensis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

Picking a way forward: valuing and managing traditional shellfish gathering for Littorina littorea

Aquatic Living Resources, 2018
Littorina littorea (periwinkles) have been harvested by hand picking from the shore since prehistoric times. Harvests are generally unregulated, catches are not linked to particular shores and fisheries statistics are considered to be unreliable.
