Abstract Background and objectives: Meningitis is one of the most common infectious of the central nervous system (CNS), defined as an inflammation of the meninges. LIF is a potent pro-inflammatory factor. Cerebrospinal fluid (CSF) contains the growth factors and cytokines whose concentrations have been changed in most neurological diseases. The aim of this study was to determine the LIF conce...
Background: Proposing a strategy for sellar reconstruction in endoscopic transsphenoidal transsellar approach for pituitary adenoma. Methods: 240 patients with pituitary adenoma underwent pure endoscopic endonasal transsphenoidal surgery. Intra-operative CSF leaks were classified as grade 0, no observable leak grade 1, CSF dripping through an arachnoid membrane defect of less than 1 ...
A novel strategy to increase protein expression yield is unintended induction of expression in complex media, called auto-induction. This method can be used to express proteins under control of the lac promoter without any need to monitor bacterial growth pattern, and addition of specific expression inducers such as Isopropyl β-D-1-thiogalactopyranoside (IPTG) at proper time. In the present stu...
Background: Human granulocyte colony-stimulating factor (hG-CSF) can serve as valuable biopharmaceutical for research and treatment of the human blood cancer. Transplastomic plants have been emerged as a new and high potential candidate for production of recombinant biopharmaceutical proteins in comparison with transgenic plants due to extremely high level expression, biosafety and many other a...
transforming growth factor β2 up-regulates gm-csf gene in human bladder carcinoma cell line htb 5637
transforming growth factor betas are multifunctional polypeptides in the cytokine superfamily. they have a growth inhibitory role on hemopoietic progenitor cells in semisolid colony assay as well as in long-term bone-marrow culture. tgf - β2 represses stromal cells, stem cell factor gene transcription, and decreases the stability of c-kit transcripts in hemopoietic cells. tgf-β also modulates g...
Temporal regulation of M-phases of the cell cycle requires precise molecular mechanisms that differ among different cells. This variable regulation is particularly clear during embryonic divisions. The first embryonic mitosis in the mouse lasts twice as long as the second one. In other species studied so far (C. elegans, Sphaerechinus granularis, Xenopus laevis), the first mitosis is also longe...
we describe the development of enterovirus meningoencephalitis associated with increased adenosine deaminase in cerebrospinal fluid of a 12-year-old boy, a known case of hypogamaglobulinemia despite monthly replacement of ivig. the patient was referred to our center with fever, headache and vomiting for 10 days. csf analysis was compatible with aseptic meningoencephalitis but high csf protein (...
Background & Aim : Hyperglycemia and hyperglycorrha ch ia are common associations of febrile seizures. Rapid release of cortisol and adrenaline after seizures as a stress reaction induces elevated glucose concentration. During fever release of interleukin-1 beta, an endogenous pyrogenic cytokine, inhibits insulin release and stimulates the secretion of cortisol. This may explain the correlat...
