learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Abstract Background: Diabetes is a metabolic chronic disorder that makes it difficult to heal wounds because of its complications. To this point, many studies on the use of mesenchymal stem cells in wound healing process particularly diabetic ulcers have been done. In this study, we evaluate the impact of mesenchymal stem cells-derived conditioned medium (MSC-CM) on diabetic wound strength. Mat...
Introduction: Semaphorin 3A (Sema 3A) is a secreted protein, which plays an integral part in developing the nervous system. It has collapse activity on the growth cone of dorsal root ganglia. After the development of the nervous system, Sema 3A expression decreases. Neuropilin 1 is a membrane receptor of Sema 3A. When semaphorin binds to neuropilin 1, the recruitment of oligodendrocyte precurso...
Background and purpose: The purpose of this study was to evaluate the effect of mouse embryonic fibroblast cells conditioned medium on resumption of meiosis, in vitro maturation of immature mouse oocytes, fertilization and derived embryos development. Material and Methods: Immature oocytes denuded at the germinal vesicle (GV) stage were obtained from female NMRI mice 46-48 hrs after injecti...
Background: Non-alcoholic fatty liver disease (NAFLD) constitutes a global pandemic. An intricate network among cytokines and lipids possesses a central role in NAFLD pathogenesis. Red blood cells comprise an important source of both cytokines and signaling lipids and have an important role in molecular crosstalk during immunometabolic deregulation. However, their role in NAFLD has not been tho...
When conditioning involves a consistent temporal relationship between the conditioned stimulus (CS) and unconditioned stimulus (US), the expression of conditioned responses within a trial peaks at the usual time of the US relative to the CS. Here we examine the temporal profile of responses during conditioning with variable CS-US intervals. We conditioned stimuli with either uniformly distribut...
Background: Adipose tissue stem cells (ASCs) cause faster repair of damaged tissue posttransplantation by releasing growth factors in neurodegenerative diseases. ASCs secrete factors in the culture medium called conditioned medium (CM) in vitro. This study investigated the expression of neurotrophin genes in vitro culture and transplant of ASCs in Parkinsonian rats. Materials and Methods: In th...
We developed an in vitro odor-aversion conditioning system in the terrestrial mollusk, Limax, and found a behavioral correlate of network oscillation in the olfactory CNS. We first examined the odor-induced behavior of Limax, after odor-aversion conditioning in vivo. Shortening of mantle muscles was specifically observed in response to aversively conditioned odors. We previously identified that...
