1. Effects of growth hormone in the central nervous system
ABSTRACT Growth hormone (GH) is best known for its effect stimulating tissue and somatic growth through the regulation of cell division, regeneration and proliferation. However, GH-responsive neurons are spread over the entire central nervous system, suggesting that they have important roles in the brain. The objective of the present review is to summarize a

2. Serotonin induces or inhibits neuritic regeneration of leech CNS neurons depending on neuronal identity
Recovery of motor function after central nervous system (CNS) injury is dependent on the regeneration capacity of the nervous system, which is a multifactorial process influenced, among other things, by the role of neuromodulators such as serotonin. The neurotransmitter serotonin can promote neuronal regeneration but there are also reports of it causing rest

3. Inside-out and standard vein grafts associated with platelet-rich plasma (PRP) in sciatic nerve repair. A histomorphometric study
Abstract Purpose: To evaluated the tubulization technique with standard and inside-out vein, filled or not with platelet-rich plasma (PRP), in sciatic nerve repair. Methods: Seventy male Wistar rats were randomly divided into five groups: IOVNF (Inside-Out Vein with No Filling); IOVPRP (Inside-Out Vein filled with PRP); SVNF (Standard Vein with No Fillin

4. Restoration of sensory dysfunction following peripheral nerve injury by the polysaccharide from culinary and medicinal mushroom, Hericium erinaceus (Bull.: Fr.) Pers. through its neuroregenerative action
Abstract Peripheral nerves have the unique capability to regenerate after injury. Insights into regeneration of peripheral nerves after injury may have implications for neurodegenerative diseases of the nervous system. We investigated the ability of polysaccharide from Hericium erinaceus mushroom in the treatment of nerve injury following peroneal nerve crus

5. Efeito do plasma rico em plaquetas e da eritropoietina na regeneração do nervo ciático de ratos wistar
Injuries to the peripheral nervous system present a challenge for regenerative medicine. The study investigated the effects of platelet-rich plasma (PRP) and erythropoietin (EPO), alone or in combination, in the regeneration of peripheral nerve in rats. The work was developed in three phases using 70 rats. The first phase, evaluated the platelet concentratio

6. Enxerto sintético e biológico, com e sem preenchimento de veia jugular externa, no reparo de nervo periférico em ratos / Syntetic and biological graft, filled with the external jugular vein in the repair of peripheral nerve in rats
Despite the development of technology involved in peripheral nerve regeneration, there is no technique that presents a recovery of the nervous tissue with completely satisfactory results. This fact arouses interest of several researchers around the word. Although the autologous nerve grafting is the current gold standard for the repair of large nerve gaps, o

7. Construction of a vector for controlled expression of chondroitinase AC for mesenchymal stem cells / Construção de um vetor para expressão controlada de condroitinase AC por células tronco mesenquimais/
Adult mammal axons fail to regenerate when damaged, generating a fundamental problem, inhibiting the recovery of injured central nervous system (CNS). The lack of full regenerative capacity of the injured CNS is due to a glial scar formation on the injury site. The glial scar is formed by astrocytes, oligodendrocyte precursor cells, and microglia, cells that

8. O uso de células-tronco adultas em modelos experimentais de crises convulsivas. / The use of adult stem cells in experimental models of seizures.
In Brazil, it is estimated that epilepsy affects from 2% of the population, about three million people at different ages and social classes. The use of antiepileptic drugs is the most common form of seizure control, although about 50- 70% of patients with epilepsy are refractory to medication. Because of difficulties in finding effective treatments, it is cr

9. Influence of the number of stitches in axonal regeneration and production of extracellular matrix in end-to-end epineural suture in the rat sciatic nerve / Influência do número de pontos na regeneração axonal e produção de matriz extracelular na sutura epineural terminoterminal no nervo ciático do rato
PURPOSE: After an injury to a peripheral nerve, its repair is performed with epineural sutures of the stumps using nylon. The inflammatory process caused by the passage of the needle and the presence of suture material with the consequent formation of scar tissue at the suture line becomes an obstacle to axonal regeneration after nerve repair. In the literat

10. Vein graft fulfilled with fat in peripheral nerve repair: a new proposal / Enxerto venoso preenchido com gordura no reparo de nervo periférico: uma nova proposta
With technology advance and the resultant production of more sophisticated equipment, microsurgery has been obtaining more attention in the experimental investigation field referred to peripheral nerves repair. It is know that in case of simple nerve section, without tissue loss, the end-to-side-neurorraphy is the most recommended technique. However, in each

11. Ação da laserterapia de baixa intensidade (830nm) na regeneração muscular de ratos idosos
The elderly still go through physical changes, especially musculoskeletal disorders such as sarcopenia, changes in central and peripheral nervous system, blood hypoperfusion, regenerative changes contributing to atrophy and muscle weakness, undermining the activities of daily living (AVL). The regenerative process happens about the determination, proliferati

12. AvaliaÃÃo morfomÃtrica da regeneraÃÃo nervosa perifÃrica em animais desnutridos precocemente
The study evaluated the peripheral nerve regeneration in adult animals that were submitted to protein malnutrition during the period known as the critical window of development. We used 20 male rats, adult, Wistar line. During the period of lactation, parts of the mothers received diet hypoproteic (casein 8%) forming the group of malnourished pups (10 animal
