rDNA Technology
Recombinant DNA technology involves combining DNA molecules from two different sources into one molecule by cutting and joining DNA strands. It includes three main tools - restriction enzymes, vectors, and host organisms. Restriction enzymes cut DNA at specific sites, vectors carry recombinant DNA, and host organisms allow the expression of inserted genes. The process involves isolating DNA, cutting with restriction enzymes, joining DNA segments by ligation, inserting into a host, and amplifying the target gene product. It has many applications in research, medicine, and industry, but also poses limitations such as environmental impacts and creating disease-causing organisms.

Recombinant dna technology
This document discusses recombinant DNA technology, which involves introducing foreign DNA into a host organism. It describes the basic steps of isolating DNA, cutting it with restriction enzymes, amplifying the gene with PCR, and ligating it into a vector for insertion into the host. The key tools used are restriction enzymes, DNA polymerase for PCR, ligase, and vectors to introduce the recombinant DNA into hosts such as bacteria. The goal is to generate organisms that produce desired proteins or have new traits.
Recombination DNA Technology
Recombinant DNA technology involves extracting DNA from different sources and chemically joining them together. Key events included Watson and Crick discovering the DNA structure in 1953, and Cohen and Boyer producing the first plasmid vector capable of replication in bacteria in 1973. The goals of rDNA technology are to isolate, characterize, and alter genes, and return them to living cells to understand diseases and improve organisms. The procedure involves isolating DNA, cutting it with restriction enzymes, joining the DNA pieces, and amplifying the recombinant DNA in bacteria. rDNA technology uses various enzymes, vectors like plasmids and phage, and techniques like PCR and hybridization. Applications include producing insulin, gene therapy, GM crops, and glowing plants.
Cloning and recombinant dna
Cloning produces genetically identical copies of organisms. Cloning of plants and animals advanced genetic technology by improving crops and domestic animals. In the 1950s, Charles Steward cloned carrots by growing single carrot cells into full plants. Animals can be cloned through embryo splitting or cell fusion, which produced Dolly the sheep. DNA cloning is important for finding and transferring genes between species, and for applications like gene therapy. Recombinant DNA technology links DNA fragments to self-replicating vectors to clone DNA in host cells like E. coli. The polymerase chain reaction (PCR) amplifies specific DNA segments and copies DNA faster than conventional cloning methods without enzymes, vectors or host cells.

introduction RDNA.pptx
This document discusses recombinant DNA technology. It emerged in 1968 with the discovery of restriction enzymes. Recombinant DNA is formed by combining DNA fragments from different organisms using molecular cloning techniques. This involves selecting a cloning vector, host organism, inserting the foreign DNA into the vector, and introducing it into the host. Bacteria are commonly used hosts due to their advantages, though eukaryotic systems are needed for proteins requiring post-translational modifications. The vector must be able to replicate within the host and have selectable markers. Transformation, transfection, and transduction are methods used to introduce recombinant DNA into hosts.
Genetic engineering and Recombinant DNA
Genetic engineering involves altering the DNA of living organisms using biotechnology. It includes techniques like changing single DNA base pairs, deleting or adding genes, or combining DNA from different species. Recombinant DNA technology is used to create recombinant DNA molecules by manipulating DNA in vitro and introducing them into host organisms. This allows bacteria to be engineered to produce human insulin through inserting the human insulin gene into bacterial plasmids. Genomic libraries can be created by ligating fragmented genomic or cDNA into plasmid vectors to transform bacteria and clone the entire genome.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Novas diretrizes da OMS para os cuidados perinatais de mais qualidade
Novas diretrizes da OMS para os cuidados perinatais de mais qualidadeProf. Marcus Renato de Carvalho
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

- 2. Recombinant DNA • DNA molecule that are extracted from different sources and chemically joined together • For example :DNA comprising animal gene be recombined with DNA from a bacterium.
- 3. Recombinant DNA Technology • The technology used for producing artificial DNA through the combination of different genetic materials (DNA) from different sources is referred to as Recombinant DNA Technology. Recombinant DNA technology is popularly known as genetic engineering. • The recombinant DNA technology emerged with the discovery of restriction enzymes in the year 1968 by Swiss microbiologist Werner Arber
- 4. Goal of DNA recombinant technology: • To isolate and characterize a gene • To make desired alteration in one or more isolated gene • To return altered genes to living cells • Alternating the genome of an organism • Understanding the hereditary disease and their cure • Improving human genome
- 5. Process of recombinant DNA tech: 1. Isolation of genetic material 2. Cutting of gene at recognition sites 3. Amplifying the gene copies through Polymerase chain reaction 4. Ligation of DNA Molecules. 5. Insertion of Recombinant DNA Into Host.
- 7. Isolation of genetic material: •The first and the initial step in Recombinant DNA technology is to isolate the desired DNA in its pure form i.e. free from other macromolecules. •
- 8. Cutting the gene at the recognition sites: • The restriction enzymes play a major role in determining the location at which the desired gene is inserted into the vector genome. These reactions are called ‘restriction enzyme digestions’. •
- 9. Amplifying the gene copies through Polymerase chain reaction (PCR): •It is a process to amplify a single copy of DNA into thousands to millions of copies once the proper gene of interest has been cut using restriction enzymes. •
- 10. Ligation of DNA Molecules: •In this step of Ligation, the joining of the two pieces – a cut fragment of DNA and the vector together with the help of the enzyme DNA ligase. •
- 11. Insertion of Recombinant DNA Into Host: • In this step, the recombinant DNA is introduced into a recipient host cell. • This process is termed as Transformation. • Once the recombinant DNA is inserted into the host cell, it gets multiplied and is expressed in the form of the manufactured protein under optimal conditions. •
- 13. Application of recombinant DNA tech: • DNA technology is also used to detect the presence of HIV in a person. • Gene Therapy – It is used as an attempt to correct the gene defects which give rise to heredity diseases. • Clinical diagnosis – ELISA is an example where the application of recombinant • Recombinant DNA technology is widely used in Agriculture to produce genetically-modified organisms such as Flavr Savr tomatoes, golden rice rich in proteins, and Bt-cotton to protect the plant against ball worms and a lot more. • In the field of medicines, Recombinant DNA technology is used for the production of Insulin.
