The EPA Catchments Unit held its 2018 annual Catchment Management Network Meeting on 14 November. All our local authorities and many other public bodies are invited to this meeting to talk about how to protect and improve Ireland's waters.
Phase 1 of the Development Plan of International Navigation on the Lancang-Mekong River (LMDP) aims to improve navigation in the Mekong mainstream from the Golden Triangle to Luang Prabang.
Projects include the development of three cargo ports at Xiengkok, Pak Beng and Luang Prabang in Laos; the improvement and maintenance of 146 rapids and shoals; and the construction of four emergency response and rescue ships and 1199 aids to navigation.
The environmental study aims to engage riparian communities, MRC member countries and local government in an exploration of the potential environmental impacts of the LMDP, and to support Mekong countries in ensuring that potential impacts of the LMDP are managed through appropriate enhancement and mitigation measures.
Implementation of the study includes:
- Key issues for biodiversity and navigation development
- Trends in the key issues without the LMDP
- Impacts of the LMDP on each of these trends
- Risks to be avoided or mitigated and benefits to be enhanced

Similar to 4. Two years on the ground identifying problems and fixing them - Carol McCarthy, LAWPRO (20)
Jenny Deakin from the EPA Catchments Unit gave a Teagasc Signpost Seminar on April 20 2021. The seminar covered water quality, focused on the agricultural sector, and the solutions needed to improve water quality, and new tools to target the right measure in the right place. This includes upgraded Pollution Impact Potential Maps for Nitrogen and Phosphorus, together with overland flow and focused delivery points.
On 25 November 2020 the EPA published Ireland’s Environment - An Integrated Assessment 2020 which provides an assessment of the overall quality of Ireland's environment, the pressures being placed on it and the societal responses to current and emerging environmental issues.
This plain English fact sheet outlines the work done by the EPA in monitoring Ireland’s rivers.
Ireland has more than 73,000 km of river channels. If placed end-to-end, they could encircle the Earth almost twice. Three-quarters of these channels are very small streams that typically flow into larger rivers.
Biological monitoring has been carried out in Irish rivers since 1971. The current national river monitoring programme covers more than 13,000 km of river channel.
The national monitoring programme is run by the EPA and focuses on the main river channels rather than the smaller streams. The programme includes more than 2,800 sites sampled for biology, with almost half of these being sampled for physical and chemical parameters.
This plain English fact sheet outlines the work done by the EPA in monitoring phytoplankton in Ireland's marine environment.
The EPA and the Marine Institute sample phytoplankton in estuaries and coastal waters around Ireland. They carry out sampling three times during the summer and once during winter. At each location, they take water samples just below the surface and above the seabed. They use the samples to assess how much phytoplankton is in the water and what species are present.
Phytoplankton are tiny, free-floating plants found suspended in the world’s oceans. Their name comes from Greek and means ‘plant drifter’. They are carried along by ocean currents and are usually found floating near the surface of the water. Like all plants they need sunlight to grow.
The main sources of nutrients around Ireland’s coast are discharges from wastewater treatment plants and run off from agricultural land. Phytoplankton in the estuaries and coastal waters around Ireland are monitored by the EnvironmentalProtection Agency (EPA) and the Marine Institute. They monitor phytoplankton to assess the quality (status) of our marine environment. They must do this as part of the requirements of the European Water Framework Directive.
This plain English fact sheet outlines the work done by the EPA in monitoring Ireland’s marine environment.
Ecologically healthy marine waters are a valuable natural resource. They support a rich and diverse range of ecosystems, habitats and species, and they are also a source of food – from wild fisheries and aquaculture. They are also important for recreational activities and tourism.
Transitional and coastal waters are assessed under the European Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). Having coordinated frameworks for water quality for all the water bodies in Ireland, and across Europe, allows us to compare our results with other countries. It allows us to see what works to help us make sure all our water bodies achieve at least ‘good’ status, and no deterioration occurs.
This plain English fact sheet outlines the work done by the EPA in monitoring Ireland’s lakes.
A total of 225 lakes are currently included as part of the national surface waters monitoring programme run by the EPA, this covers around 80% of the surface area of all lakes in Ireland.
This includes:
• all lakes greater than 50 hectares
• lakes that are used for supplying drinking water
• lakes that are of regional, local or scientific interest
This Plain English fact sheet outlines the work done by the EPA in monitoring aquatic plants in Irish lakes.
Aquatic plants are good at showing if the quality of the water is good or bad and play an important role in lake ecology by providing food and a habitat for many smaller plants, animals and birds.
They also:
• provide shelter for young fish
• help to improve the clarity of the water
• help stabilise lake shore banks
• reduce the amount of sediment being suspended in the water
The Environmental Protection Agency (EPA) monitors these aquatic plants at more than 10,000 sites in over 200 lakes once every three years.

Seminar of U.V. Spectroscopy by SAMIR PANDASAMIR PANDA
Spectroscopy is a branch of science dealing the study of interaction of electromagnetic radiation with matter.
Ultraviolet-visible spectroscopy refers to absorption spectroscopy or reflect spectroscopy in the UV-VIS spectral region.
Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.
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 .

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
