Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
Autophagy is the basic catabolic mechanism which involves mainly cell degradation of unnecessary or dysfunctional cellular components with the actions of lysosomes. The breakdown of cellular components can ensure cellular survival during starvation by maintaining their cellular energy levels. If Autophagy regulated, ensures the synthesis, degradation and recycling of the cellular components. During this autophagy process, targeted cytoplasmic constituents are isolated from the rest of the cell within the autophagosomes, which fuses with lysosomes and recycled or degraded. There are three different kinds of autophagy that are commonly described; microautophagy ,macroautophagy, and chaperone-mediated autophagy. With the context of disease, autophagy has been observed as an adaptive response to survival, whereas in other cases it appears to promote cell death and morbidity. There are three main pathways involved in autophagy and these are mediated by the autophagy-related genes and their associated enzymes. Macroautophagy is the main pathway, occurring mainly to eradicate the damaged cell organelles or unused proteins which involve the formation of a double membrane around cytoplasmic substrates resulting in the organelle known as an autophagosome. Microautophagy, on the other hand, involves the direct engulfment of cytoplasmic material into the lysosome which occurs by invagination i.e the inward folding of the lysosomal membrane, or cellular protrusion. Chaperone-mediated Autophagy is a very complex and specific pathway, involving the recognition by the hsc70-containing complex.
