INVESTIGATION ON THE MORPHOLOGY AND PROPERTIES OF AGGREGATE STRUCTURES OF NATURAL PHOSPHOLIPIDS IN AQUEOUS SYSTEM USING CRYO-TEM

open access: yesIndonesian Journal of Chemistry, 2012
Cryogenic transmission electron microscopy (Cryo-TEM) was used to investigate the aggregates morphology and properties of candle tree (Aleurites moluccana) endosperm, sesame (Sesamum indicum L.

Effect of Interactions Between Anionic Vesicles and a Cationic Terpolymer in Concentrated Solution Regime: Morphology and Size Changes of the Vesicular Particles [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2016
Interactions between polyelectrolytes and oppositely charged vesicular particles have many possible applications in drug delivery or gene therapy. Formation of vesicular structures by 2-(propylcarbamoyl) terephthalic acid heptaisobutyl POSS (POSS DCA) in

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Revisiting the Role of Clathrin-Mediated Endoytosis in Synaptic Vesicle Recycling

open access: yesFrontiers in Cellular Neuroscience, 2018
Without robust mechanisms to efficiently form new synaptic vesicles (SVs), the tens to hundreds of SVs typically present at the neuronal synapse would be rapidly used up, even at modest levels of neuronal activity.

Vesicle dynamics in elongation flow: Wrinkling instability and bud formation

open access: yes, 2007
We present experimental results on the relaxation dynamics of vesicles subjected to a time-dependent elongation flow. We observed and characterized a new instability, which results in the formation of higher order modes of the vesicle shape (wrinkles ...

Synaptic proteins promote calcium-triggered fast transition from point contact to full fusion. [PDF]

open access: yes, 2012
The molecular underpinnings of synaptic vesicle fusion for fast neurotransmitter release are still unclear. Here, we used a single vesicle-vesicle system with reconstituted SNARE and synaptotagmin-1 proteoliposomes to decipher the temporal sequence of ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

5‐Fluorouracil treatment represses pseudouridine‐containing miRNA export into extracellular vesicles

open access: yesJournal of Extracellular Biology
5‐Fluorouracil (5‐FU) has been used for chemotherapy for colorectal and other cancers for over 50 years. The prevailing view of its mechanism of action is inhibition of thymidine synthase leading to defects in DNA replication and repair. However, 5‐FU is

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
