High capacity chromatography resin for the capture and purification of monoclonal antibodies
Tosoh Bioscience, a provider of chromatographic solutions for the isolation and analysis of biomolecules, introduced a new Protein A chromatography resin designed for the purification of monoclonal antibodies (mAbs). It is well-suited for high capacity capturing of immunoglobulin out of high titer feedstock. TOYOPEARL AF-rProtein A HC-650F achieves 30% to 50% greater antibody adsorption than similar products. It exhibits dynamic binding capacities of greater than 70 g/L at residence times of 5 minutes and greater than 50 g/L at residence times of 2 minutes with feedstock titers from 1 g/L to more than 10 g/L.
The recombinant ligand that is linked to the well proven methacrylic polymer backbone of TOYOPEARL media has been engineered to maintain capacity even after repeated exposure to alkaline solution. Its multipoint attachment to the TOYOPEARL matrix further enhances chemical and thermal stability. In practice this pays off for a low level of Protein A leaching and also for a high resistance to alkaline solutions applied in cleaning-in-place (CIP) procedures. Due to its rigid polymer matrix TOYOPEARL AF-rProtein A HC-650F also provides excellent pressure flow characteristics.
Protein A resins constitute a substantial cost in state-of-the-art mAb purification processes. Factors such as operating cycles, capacity, and mAb titer can have an impact on total costs associated with mAb purification. The high capacity of the new TOYOPEARL AF-rProtein A HC-650F resin and its high alkaline resistance increase product throughput, reduce operating costs and increase manufacturing productivity.
Nowadays, Cell and Molecule Analysis are critical steps for studying cellular mechanisms in any Life Sciences lab, as it offers additional information about Intracellular Molecular Targets in a real Biological environment.

Determination of Anions by Ion Chromatography
1 SCOPE AND FIELD OF APPLICATION
This method is suitable for the determination of inorganic anions in Ammonia Solution in the range 100 ppb to 50 ppm m/v.
2 PRINCIPLE
The sample is passed through a column of anion exchange resin, on which the anions are absorbed and separated. They are then eluted with dilute sodium carbonate/sodium hydrogen carbonate solution and passed through a suppressor. This replaces the cations with hydrogen ions and thus reduces the background conductivity of the eluent. Final measurement is by conductivity

Untuk menjawab pertanyaan di atas, mari kita mendiskusikan apa itu protein dan seberapa penting zat ini bagi tubuh. Protein merupakan satu dari tiga jenis zat gizi makro yang dibutuhkan tubuh. Zat gizi ini terdiri dari beberapa unsur kimia seperti karbon (C), hidrogen (H), oksigen (O), dan nitrogen (N). Unsur lain seperti fosfor dan sulfur pun terkadang ikut andil dalam proses pembentukan protein.
Menurut tabel Angka Kecukupan Gizi (AKG), usia 17–60 tahun disarankan perlu mengonsumsi protein sekitar 62–66 gram per hari bagi pria dan 56–59 gram per hari bagi wanita. Namun, jumlah asupan protein harian juga perlu disesuaikan dengan kebutuhan masing-masing, tergantung dari usia, kepadatan aktivitas, dan tingkat stres metabolik.
Dari penjelasan seputar protein di atas, dapat dipahami bahwa zat ini sangat diperlukan oleh tubuh. Protein bahkan bisa membantu memperbaiki jaringan sel yang rusak sehingga mampu kembali bekerja dengan optimal. Protein juga merupakan zat gizi yang ditemukan di seluruh tubuh termasuk rambut, otot, tulang, dan kulit. Bahkan, 20% tubuh manusia itu terbentuk karena protein.
Protein terbentuk dari bahan pembangun yang dikenal dengan asam amino. Terdapat sekitar 20 jenis asam amino. Sembilan di antaranya merupakan asam amino esensial, sedangkan sisanya merupakan asam amino non-esensial. Asam amino non-esensial bisa diproduksi sendiri oleh tubuh. Namun, lain halnya dengan asam amino esensial yang memerlukan sumber lain agar tubuh terus mendapatkan asupan asam amino esensial. Asam amino tersebut meliputi:
Isoleusina
Lisina
Metionina
Treonin
Valina
Histidina
Leusina
Fenilalanina
Triptofan
Sembilan asam amino esensial di atas diperoleh dengan mengonsumsi makanan yang kaya akan protein, baik bersumber dari hewani maupun nabati.
Apa Fungsi Protein Bagi Tubuh?
Berikut ini hal-hal yang perlu Anda ketahui mengenai fungsi protein bagi tubuh.
Membangun dan Memperbaiki Jaringan Tubuh
Seperti yang sudah dijelaskan sebelumnya, protein berperan penting dalam memperbaiki sel tubuh yang rusak. Protein juga berfungsi memelihara sel yang terdapat di seluruh tubuh agar bisa berfungsi secara optimal. Biasanya, jumlah protein yang diperlukan untuk memperbaiki dan membangun sel tubuh akan stabil setiap harinya.
Membentuk Hormon dan Enzim
Sel mengandung enzim yang berfungsi menimbulkan reaksi biokimia dalam tubuh. Enzim akan bereaksi ketika terjadi kontraksi otot, pencernaan makanan, dan penghancuran racun. Enzim tersebut terbentuk karena adanya protein. Selain itu, protein juga bertugas membentuk hormon tubuh. Hormon berfungsi mengirimkan sinyal sekaligus mengatur proses biologis antara jaringan, organ, dan sel.
Sumber Energi
Selain karbohidrat dan lemak, protein merupakan sumber energi yang diperlukan oleh tubuh. Lemak memasok energi sebanyak 9 kalori/gram, sedangkan karbohidrat dan protein memasok sebanyak 4 kalori/gram. Untuk memperoleh energi, tubuh akan mengandalkan lemak dan karbohidrat.
It is the preparation of tissues for microscopic examination.
It is an effective diagnostic tool in clinical pathology.
Histological preparations reveal normal tissue structure, tissue abnormalities and cancerous conditions.
The Special Stains general reference guide provides a general overview of special stains functionality and clinical utility. The guide describes the clinical application of the various assays, the appropriate tissue controls to be used, and some technical considerations as they relate to each of the unique histochemical stains.
Decalcification: Unveiling Structures Beneath the Mineral Veil
What is it? Decalcification removes calcium salts from tissues like bone and teeth, making them soft and sliceable for microscopic analysis.
Why do it? Hardened tissues can't be sectioned effectively and interfere with staining. Decalcification allows clear visualization of cellular and structural details.
How is it done? Different methods exist, like using weak acids or chelating agents, each with its pros and cons. The choice depends on tissue type, processing time, and desired preservation level.
Knowing when to stop: Monitoring techniques like X-rays or physical assessment help determine the optimal endpoint to avoid over-decalcification and tissue damage.
Beyond bone: Decalcification finds applications in diverse fields like paleontology, pathology, and cancer research.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

in Scintillation Counting
The components of the LSC cocktail may represent a hazard or a

For many experiments, only a small percentage of the samples
counted will have significant radioactivity, so disposal of the LSC
is the predominating issue.
Fortunately, biodegradable LSC cocktails have been developed,
