In epidemiology, a disease vector is any living [ 1] agent that carries and transmits an infectious pathogen such as a parasite or microbe, to another living organism. [ 2][ 3] Agents regarded as vectors are mostly blood-sucking insects such as mosquitoes. The first major discovery of a disease vector came from Ronald Ross in 1897, who ...
Vector control taking place in the Southern United States during the 1920s. Vector control is any method to limit or eradicate the mammals, birds, insects or other arthropods (here collectively called "vectors") which transmit disease pathogens. The most frequent type of vector control is mosquito control using a variety of strategies.
The most commonly used gammaretroviral vector is a modified Moloney murine leukemia virus (MMLV), able to transduce various mammalian cell types. MMLV vectors have been associated with some cases of carcinogenesis. [26] Gammaretroviral vectors have been successfully applied to ex vivo hematopoietic stem cell to treat multiple genetic diseases. [27]
the stride of an array, or the amount of memory occupied by each element of the array. A program then can refer to the array (or other dope-vector-using object) by referring to the dope vector. This is commonly automatic in high-level languages. Getting to an element of the array costs a tiny bit more (commonly one instruction, which fetches ...
Sandfly species transmit the disease leishmaniasis, by acting as vectors for protozoan Leishmania species, and tsetse flies transmit protozoan trypansomes (Trypanosoma brucei gambiense and Trypansoma brucei rhodesiense) which cause African Trypanosomiasis (sleeping sickness). Ticks and lice form another large group of invertebrate vectors.
Vector processor. In computing, a vector processor or array processor is a central processing unit (CPU) that implements an instruction set where its instructions are designed to operate efficiently and effectively on large one-dimensional arrays of data called vectors. This is in contrast to scalar processors, whose instructions operate on ...
How vectors work to transfer genetic material. Gene therapy utilizes the delivery of DNA into cells, which can be accomplished by several methods, summarized below. The two major classes of methods are those that use recombinant viruses (sometimes called biological nanoparticles or viral vectors) and those that use naked DNA or DNA complexes (non-viral methods).
Expression vectors are the basic tools in biotechnology for the production of proteins . The vector is engineered to contain regulatory sequences that act as enhancer and promoter regions and lead to efficient transcription of the gene carried on the expression vector. [ 1] The goal of a well-designed expression vector is the efficient ...
