Deleting Models

Như các bạn đã biết thì Laravel hỗ trợ cho chúng ta nhiều cách để tương tác với cơ sở dữ liệu. Và eloquent ORM là một thế mạnh rất lớn Laravel có trong khi các framework không hỗ trợ. Bài giảng này sẽ trình bày một số nội dung cơ bản về Eloquent ORM trong Laravel, mời các bạn cùng tham khảo.

Eloquent ORM đi kèm với Laravel cung cấp một API ActiveRecord đơn giản và tiện lợi cho giao tiếp với database. Mỗi database table sẽ có một "Model" tương ứng để tương tác với table đó. Model cho phép bạn query dữ liệu trong table, cũng như chèn thêm các dữ liệu mới. Bài giảng này sẽ tiếp tục cung cấp cho người học những kiến thức cơ bản về eloquent ORM trong Laravel.

Here we use a model of stochastic birth and death for mapping gene family evolution onto a phylogeny, and show that it can be efficiently applied to multispecies comparisons. The model offers the opportunity for researchers to make stronger inferences regarding the role of natural selection and changing duplication and deletion rates in gene family expansion or contraction. The work is performed as a part of the first author’s MS thesis under the second author’s supervision.

Most (78%) mitochondrial genomes in the studied mutant strain of Drosophila subobscura have undergone a large-scale deletion (5 kb) in the coding region. This mutation is stable, and is transmitted intact to the offspring. This animal model of major rearrangements of mitochondrial genomes can be used to analyse the involvement of the nuclear genome in the production and maintenance of these rearrangements.

Ribonuclease L (RNase L) is a key enzyme in the 2-5A host defense system, and its activity is strictly regulated by an unusual 2¢,5¢-linked oligoadenylate (2-5A).A bipartite model, in which the N-terminal half of RNase L is responsible for the 2-5A binding and the C-terminal half alone is able to hydrolyse the substrate RNA, has been proposed on the basis of the results of deletion mutant analyses [Dong, B.& Silverman, R.H.

The role of the two disulfide bonds (Cys4–Cys60 and Cys18–Cys29) in the activity and stability of goose-type (G-type) lysozyme was investigated using ostrich egg-white lysozyme as a model. Each of the two disulfide bonds was deleted separately or simultaneously by substituting both Cys residues with either Ser or Ala.

Chromosomal Instability in Solid Tumors Solid tumors are generally highly aneuploid, containing an abnormal number of chromosomes; these chromosomes also exhibit structural alterations such as translocations, deletions, and amplifications. Again, colon cancer has proven to be a particularly useful model for the study of chromosomal instability (CIN). As described above, some familial cases are characterized by the presence of MIN.
