Accurate concentration for virus and virus-like particles can be determined by multi-laser nanoparticle tracking analysis due to the fact they are nanoparticles. Other biologically relevant materials will have sizes that are close to those of viruses, whether they are protein aggregates that provoke an unwanted immune response or exosomes with a similar size and do not provoke an immune response.
In this webinar, Dr. Jeff Bodycomb will discuss the use of multi-laser nanoparticle tracking analysis (NTA) to determine the size distribution and concentration of these species, the latter which is correlated to viral infectivity.

How and Why to Analyze Ceramic Powder ParticlesHORIBA Particle
Packing density, mechanical strength, and processing of ceramics are all affected by the size distribution of the powders. Therefore, particle size analysis is an important quality control step. Due to its wide size range and flexibility, laser diffraction is often the preferred method of analysis. Laser diffraction can be used for particles with sizes from 10’s of nanometers to millimeters. In this webinar, Dr. Jeff Bodycomb of HORIBA Scientific discusses particle analysis of ceramic particles, including electronic materials and common oxides. He will cover the basic principles of analysis, practical methods for obtaining good data, and example data.

Particle Classroom Series V: Sampling and DispersionHORIBA Particle
The goal of a particle analysis is to understand the properties of a material, whether it is the size distribution of particles that are manufactured today or the size distribution of particles in the truck that just arrived. Naturally, a particle analyzer only encounters a tiny fraction of that material, the sample.
In addition, particles can be bound together to form agglomerates that do not represent the underlying materials. The instrument will then measure the agglomerates, not its constituent particles. In this webinar, Jeff discusses how to improve data quality by obtaining a representative sample and effectively disperse the sample to remove or prevent agglomerates.

Interpreting Laser Diffraction Results for Non-Spherical ParticlesHORIBA Particle
Particle shape can have a profound impact on particle size distribution (PSD) measurements. In the case of Laser Diffraction, the shape and aspect ratio of particles alter the diffraction pattern used to determine PSD, which is calculated on the basis of equivalent spherical diameter. For instance, it has been established that the reported size of an ellipsoid is always smaller than the physical major dimension of the particle. Furthermore, when non-spherical particles align within a flowing sample, laser diffraction instruments typically report a bi-modal size distribution even in the case of monodisperse samples.
Equipped with only qualitative knowledge of particle shape, the particle analyst can resolve this inherent ambiguity and use laser diffraction to obtain quantitative information (such as aspect ratio) about non-spherical particles. This webinar explains the origin of this effect, describes how to interpret PSD data in such cases, and demonstrates several practical applications for measurements of crystals, bacteria, and clays.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
