The secretion and retraction processes of pollination drops of ancient Platycladus orientalis and their response to different pollen types

open access: yesFrontiers in Plant Science
IntroductionThe pollination drop (PD) is an important ovular secretion that occurs during the pollination stage in gymnosperms.MethodsIn this study, ancient Platycladus orientalis trees near the Mausoleum of the Yellow Emperor were selected to ...

Role of Phospholipases in Fungal Fitness, Pathogenicity and Drug Development- Lessons from Cryptococcus neoformans

open access: yesFrontiers in Microbiology, 2010
Many pathogenic microbes, including many fungi, produce phospholipases which facilitate survival of the pathogen in vivo, invasion and dissemination throughout the host, expression of virulence traits and evasion of host immune defense mechanisms.

Ultrastructure and oil secretion in Hiptage sericea Hook

open access: yesActa Societatis Botanicorum Poloniae, 2014
The oil secreting glands of Hiptage sericea Hook. consist of three regions: epithelial, sub-epithelial and sub-glandular. In early stages, the oil secreting cells are characterized by the presence of plastids with starch grains and electron translucent ...

Lipoproteins in a nonrecirculating perfusate of rat liver

open access: yesJournal of Lipid Research, 1974
Rat livers were perfused in a nonrecirculating system for 30–40 min with Krebs-Ringer bicarbonate–0.1% glucose solution gassed with 95% O2–5% CO2 at 37°C at a flow rate of 3 ml/g/min.

The secreted secret of PCSK9 [PDF]

open access: yesScience-Business eXchange, 2009
Amgen researchers have demonstrated that blocking secreted PCSK9 in mice and nonhuman primates lowers LDL cholesterol. The findings bolster the case for an antibody-based approach to blocking the protein, which is a genetically validated target for hypercholesterolemia.

Tau Secretion: Good and Bad for Neurons

open access: yesFrontiers in Neuroscience, 2019
In Alzheimer’s disease (AD), neurofibrillary tangles (NFTs), lesions composed of hyperphosphorylated and aggregated tau, spread from the transentorhinal cortex to the hippocampal formation and neocortex.

Nasal mucosa secretion exudation response to cold air in bronchial asthma patients

open access: yesБюллетень сибирской медицины, 2017
Background. Combined airway hyper responsiveness to cold and hypoosmotic stimuli in asthma patients results in impairment of lung respiration function and poor disease control compared to patients with isolated airway hyper responsiveness to only one of ...

Milk lipid secretion: recent biomolecular aspects

open access: yesBiomolecular Concepts, 2012
Neonates of most species depend on milk lipids for calories, fat-soluble vitamins, and bioactive lipid components for growth and development during the postnatal period.

Distinct ontogenic patterns of overt and latent DGAT activities of rat liver microsomes

open access: yesJournal of Lipid Research, 2002
We have studied the ontogeny of the two functional diacylglycerol acyltransferase (DGAT) activities (overt and latent) during postnatal development in rat liver. We find that the ontogenic patterns of the two are highly distinct.
