Raamsdonk beijing immunoassay validation v2
Methods are needed that are able to discriminate between ruminant and non-ruminant PAPs for facilitating a safe re-introduction of non-ruminant PAPs in aqua feed. Therefore, two immunoassays, MELISA-TEK® and Reveal, have been tested in an interlaboratory study for their capability to detect ruminant PAPs processed according to European conditions. 15 non-ruminant animal protein samples were spiked at 0.5%, 1.0% and 2.0% with ruminant material, sterilised at either 133 oC or 137 oC, and combined with the six basic materials as blanks. Fourteen participants passed the entrance test and investigated the 21 samples. For both MELISA-TEK® and Reveal specificity and sensitivity were at 97% or higher. Concordance and accordance were also higher than 95%, except for the concordance of the blank samples with Reveal (94.2%). The results indicate that both assays are validated at 0.5% and higher for the detection of ruminant PAPs (sterilised at 133 oC) with non-ruminant PAPs as matrix. Given the 2% upper limit of ruminant PAPs in non-ruminant PAPs for avoiding an increase in BSE incidents, these methods are fit for monitoring non-ruminant PAPs intended for aqua feed.

Multicopy reference assay (MRef) — a superior normalizer of sample input in D...
Copy number variations (CNVs) and alterations (CNAs) are a source of genetic diversity in humans and are often pathogenic. Numerous CNVs and CNAs are being identified with various genome analysis platforms, including array comparative genomic hybridization (aCGH), single nucleotide polymorphism (SNP) genotyping platforms, and next-generation sequencing. Independent verification of copy number changes is a critical step. Quantitative real-time PCR (qPCR) is a classic method to verify microarray copy number findings. Traditional copy number assays that use qPCR typically rely on a putative single-copy gene reference assay (e.g., RNase P or TERT) to normalize the DNA input for downstream ΔΔCT-based copy number calculation for comparison to a reference genome. When applied to cancer samples, these single-copy reference assays may no longer be a reliable indicator of DNA input due to the presence of complex chromosome composition (both in chromosome number and structure). To meet the need for an accurate DNA input normalizer, especially for heterogeneous tumor samples, QIAGEN developed a multicopy reference (MRef) assay for real-time PCR copy number analysis. This assay, in conjunction with QIAGEN’s greater than 10 million genomewide copy number assays and pathway- and disease-focused copy number PCR arrays (Figure 1), provides a successful solution for copy number analysis. This article will address the assay design considerations, development, and performance of this multicopy reference (MRef) assay.
New Progress in Pyrosequencing for DNA Methylation
Pyrosequencing is a highly flexible technology that lets you rapidly analyze short- to medium-length sequences fast and quantitatively with high accuracy. The real-time, high-resolution sequence output makes the technology highly suitable for applications including complex mutation analysis, microbial identification and DNA methylation quantification.
The main bottleneck in Pyrosequencing has been limited sequence length, which is critical for some applications. Our new technology, software, and chemistry overcome this bottleneck and give sequence reads that are typically twice as long as those from previous PyroMark systems. The new PyroMark Q24 Advanced system also reduces background noise, improving quantification even at sites distant from the sequencing start. The new system is ideal for applications requiring analysis of longer sequences, such as DNA methylation analysis in epigenetic research, frequency determination in mutation analysis, and various de novo sequencing applications.
In this presentation, we will discuss the following applications and technology improvements:
• DNA methylation analysis at single base resolution at CpG and CpN sites
• Improved quantification of sequence variations at any sequence position
• Easy and improved base calling functionality
Quality Control of RNA Samples — For Gene Expression Results You Can Rely On
RNA quality control is an important part of gene expression workflows to help ensure reliable and reproducible results. Key parameters for RNA quality control include purity, quantity, and integrity. Automated platforms like QIAGEN's QIAxpert and QIAxcel provide fast, accurate, and reliable RNA quality control by measuring parameters such as yield, contaminants, degradation, and size distribution. Implementing RNA quality control helps reduce costs from failed or unreliable experiments and increases confidence in results.

Dr. Jeff Baxter - Lab Testing Standardization
This document summarizes a study on standardizing Trichomonas foetus DNA testing across multiple laboratories. The study aimed to minimize variables that could influence sample or testing quality. It evaluated pooling of positive samples, different sample preparation methods, and real-time PCR protocols across five feeder labs compared to a central study lab. The study found 95.6% agreement between labs and confirmed 175 of 176 positive samples as T. foetus by DNA sequencing. Pooling was found to potentially miss some positives, with 1:5 pooling missing 4% and 1:3 pooling missing 3.5% of positives. The study supports standardizing sample collection, handling, preparation and PCR analysis to increase testing accuracy and consistency.
Webinar PCR - COVID-19, 2020
Polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail. PCR was invented in 1984 by the American biochemist Kary Mullis at Cetus Corporation. It is fundamental to much of genetic testing including analysis of ancient samples of DNA and identification of infectious agents. Using PCR, copies of very small amounts of DNA sequences are exponentially amplified in a series of cycles of temperature changes. PCR is now a common and often indispensable technique used in medical laboratory and clinical laboratory research for a broad variety of applications including biomedical research and criminal forensics

This slidedeck will cover the challenges and solutions associated with multiple steps as one starts with liquid biopsy and move towards finding a new biomarker.
Accelerate Delivery of High Producing Cell Lines
Watch the interactive recording here: https://bit.ly/30FTDG0
The quest for a viable upstream process relies on generation of a cell line expressing the protein of interest. Unfortunately, the search for the best-producing clone is often compared with looking for a needle in a haystack. Making this more challenging is the pressure to get it right the first time, quickly and while mitigating risk and costs.
Although a lot of efforts are made on the clonal selection, there is often few to none optimization done on the expression cassette, including promoter and enhancer selection, or signal peptide. The statistical approach on how many clones should be screened to get to a good producer is often overlooked as well.
We combined a new generation of promoters and enhancers to improve strategies on pool and mini pool screening with both CHO-K1 and our own CHOZN® GS which helped deliver high-producing clones in an accelerated timeline. In addition, we are able to begin process development in parallel with cell line development, further reducing timelines.
In this webinar, you will learn:
* How the strategy approach can help reducing the overall timeline of cell line generation
* How we have expanded our platform by designing a completely new vector/cell/process template
* How we have worked on promoters, enhancers, pool/mini-pool approach as well as on timelines from DNA to clone

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Recycling and Disposal on SWM Raymond Einyu pptx
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

ENVIRONMENT~ Renewable Energy Sources and their future prospects.
This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
