Most Lophiiformes including Lophius species are considered to spawn egg masses called an “egg veil” or ribbon” composed of numerous mucoid chambers. However, eggs have been rarely collected in the field and thus little is known about their biological features. Here we examined embryonic development litulon also effects water temperature on from veils field. Embryonic was observed late cleavage ...

Stem cells are undifferentiated that can proliferate, regenerate, develop into differentiated cells, and produce a variety of tissues. Embryonic stem adult or somatic pluripotent the three types cells. Another classification is totipotent, multipotent, unipotent cell treatment has possibility treating degenerative disorders, cancer, restoration damaged tissues, all which now have no restricted ...

background new research proposes the pluripotency of spermatogonial cells obtained from testis. these spermatogonia-derived stem cells are called embryonic stem-like cells that express embryonic stem cell markers and differentiate to the three germ layers. objectives the aim of the present study was to generate embryonic stem-like cells from neonatal mouse testis. materials and methods the test...

teratomas are tumors originated from mature or immature tissues. teratomas are made up of one embryonic layer or all three embryonic layers (endoderm, mesoderm, or ectoderm). herein we report a 41-year-old man who presented with vertigo, vomiting, and tinnitus. after physical examination, laboratory evaluation and performing computed tomography, cholesteatoma was diagnosed, however, during radi...

background: transplantation approaches are interventions currently available to apply to the devastating problem of spinal cord injury (sci). olfactory ensheathing cell (oec) and embryonic stem cell (esc) are considered to be promising therapeutic strategies . in this study, we compared the potential use of oecs and neurally pre-differentiated escs in contusion spinal cord. methods: oecs were h...

background:   objective: this study presents an economical and simple co-culture system for pluripotent stem cells generation from neonatal mouse testis   materials and methods: isolated testicular cells were cultured in dmem/f12. characteristics of the isolated cells and obtained es-like cell were immune-cytochemically confirmed by examining the presence of plzf, vimentin, oct4 and nanog prote...

wiener index is a topological index based on distance between every pair of vertices in agraph g. it was introduced in 1947 by one of the pioneer of this area e.g, harold wiener. inthe present paper, by using a new method introduced by klavžar we compute the wiener andszeged indices of some nanostar dendrimers.

Abstract Following implantation, the human embryo undergoes major morphogenetic transformations that establish future body plan. While molecular events underpinning this process are established in mice, they remain unknown humans. Here we characterise key of morphogenesis, period between implantation and gastrulation, using single-cell analyses functional studies. First, embryonic epiblast cell...

Drought stress is one of the most important factors limiting plant growth all around the world. Plant Growth Promoting Rhizobacteria (PGPR) can significantly reduce drought stress effects on plants growth. This study was aimed to investigate the influence of PGPR (inoculation by Azospirillum lipoferum, Azotobacter chroococcum, Pseudomonas aeruginosa, and Bacillus cereus) on seed germination, se...
