Apr 8, 2022 · This work provides evidence of the presence of immature neurons in the human brain, specifically in the layer II of the cerebral cortex. Using surgical samples from epileptic patients and post-mortem tissue, we have found cells with different levels of dendritic complexity (type I and type II cells) expressing DCX and PSA-NCAM and lacking ...

If any idea explaining the origin of protein-I has not been proposed by other researchers, it becomes a problem how a functional water-soluble globular or a mature protein could be produced through random process before the first gene was created or in the absence of any genetic function. Thus, the quite difficult problem, how the first mature prot...
Before the protein 0th-order structure is explained in Sect. 4.2, I would like to discuss first what kinds of organic compounds could be produced and accumulated during chemical evolution, in order to confirm whether [GADV]-amino acids and nucleotides, which are required to synthesize [GADV]-protein and RNA, respectively, could be accumulated with ...
The bottom-up approaches in the origin-life research, which are usually carried out by experiments, are undoubtedly important to understand how life emerged on the primitive Earth. Indeed, the important insight that [GADV]-amino acids could accumulate at large amounts on the primitive Earth was obtained through experiments. As shown in so called “M...
As described in Chap. 2: Sect.1.2, it is important to understand for considering about the origin of protein, how the first mature protein was created through random processes or without gene on the primitive Earth, because both structure and function of the first protein cannot be designed in advance (Table 3.1). On the contrary, I have insisted t...
Here, I explain a protein 0th-order structure or a specific amino acid composition, in which an immature protein can be produced by random joining of amino acids at a high probability (Fig. 3.9). One of the protein 0th-order structures is the amino acid composition containing [GADV]-amino acids at roughly equal amounts. The reason, why the amino ac...
As described above, immature proteins could be formed by random joining of [GADV]-amino acids through repeated wet-drying processes without involvement from any other members, or cell structure, metabolism, tRNA, genetic code and gene, which constitute the fundamental life system. However, there is another difficult problem, which is necessary to s...
4.7.1 Evidence Showing That an Immature Protein Is Pluripotent
As described above, for creation of one EntNew mature protein, it is indispensable to detect a weak but sufficiently high activity on an immature protein (Fig. 3.14a). Therefore, all catalytic activities, which are necessary for the first life to emerge, must be contained in the whole group of immature proteins with some flexibility (Fig. 3.14b). This means that an extraordinary large number of catalytic activities must appear on one immature protein, because any activity never be detected on...
Whether or not something assumed is valid as the origin relies on whether or not it can be explained that something assumed could be produced through random process and could evolve to the modern one. According to the conditions, it can be concluded that an immature [GADV]-protein, which was produced by random joining of [GADV]-amino acids in a pro...
As described in the above strengths of protein 0th-order structure hypothesis, I am considering that I could explain the two origins of protein-I and -II with protein 0th-order structure hypothesis. (1) The first one is “How was the first protein created? (2) The second one is “How were entirely new proteins generated under the three genetic codes ...

May 5, 2023 · Immature granulocytes (IGs) develop in the bone marrow, where they give rise to neutrophils, eosinophils, and basophils . Low levels of mature granulocytes may suggest a health issue that may be serious. High IG counts suggest an infection or may point to a bone marrow condition.
For this purpose, one immature water-soluble globular protein with some flexibility, produced by the expression of one double-stranded (ds)-RNA encoding one essentially random [GADV]-amino...
The meaning of IMMATURE is exhibiting less than an expected degree of maturity. How to use immature in a sentence.
Nov 1, 2022 · The models are defined on the population level: they describe the total quantity of protein species (red, green, blue, colorless) in a growing population of cells. The quantities of protein are assumed proportional to the measured fluorescence signals, reported in relative fluorescence units (RFUs).

A single cell can contain thousands of proteins, each with a unique function. Although their structures, like their functions, vary greatly, all proteins are made up of one or more chains of amino acids. In this article, we will look in more detail at the building blocks, structures, and roles of proteins.
