@article{ author = {Nooridaloii, Mohammad Reza and Boustanipour, Elham}, title = {The molecular genetics of neurofibromatosis type 1 and its future prospective}, abstract ={Abstract   Neurofibromatosis type 1 (NF1) is an autosomal dominant tumor predisposition syndrome that is caused through loss of function mutations of a tumor suppressor gene termed neurofibromin 1. Therapeutic decisions are presently restricted for NF1-associated tumors, where treatment is often restricted to thorough surgical resection with perfect margins. In this review article, the multifunctional role of neurofibromin in tumor suppression has been discussed. While neurofibromin inhibits proliferative growth through blockade RAS-mediated signal transduction, neurofibromin should also be considered as a modulator of cell motility and cell adhesion. Through interfacing with the cytoskeleton and membrane structures, neurofibromin acts as a negative regulator of RHO/ROCK signaling pathways involved in cytoskeletal dynamics that are involved in proper neuronal expansion. The loss of function of neurofibromin through genetic mutation results in heightened cell proliferation and migration, predisposing NF1 patients to cancer. Malignant peripheral nerve sheath tumors (MPNSTs) can be developed from benign neurofibromas and are the main cause of death amongst NF1 patients. Recent researchers in MPNSTs have been attempting to reveal key molecular events that lead MPNSTs to malignancy. Advances regarding malignant drivers involved in cell migration, cell invasion and angiogenic signaling are discussed in this review, where these findings will likely influence future therapies for both NF1 and related sporadic cancers.

ODF is relatively a new dosage form which is prepared using hydrophilic polymers, which rapidly dissolve on tongue or buccal cavity and has other advantages of rapid onset of action and improved bioavailability. The aim of this study was formulation of ODF dosage forms containing alprazolam, which is a short-acting anxiolytic of the benzodiazepines class of psychoactive drugs. Materials and methods: Various polymers like hydroxy propyl methyl cellulose (HPMC6cps), sodium carboxy methyl cellulose (Na CMC), polyvinyl alcohol (PVA72000), and different plasticizers like propylene glycol (PG), polyethylene glycol (PEG400) with different percentage using solvent casting technique were used to prepare ODF formulations. Physicochemical tests including weight and thickness determination, disintegration time, assay and dissolution time were performed to find the optimum formulation. Results: The optimized formulation contained PVA72000 and PEG400 with disintegration time less than 60 seconds and acceptable dissolution rate. Conclusion: ODT dosage form of alprazolam with acceptable dissolution behavior and proper disintegration time was successfully formulated in this study.

Given the importance of the vincristine- induced hepatotoxicity during chemotherapy, the aim of this study was to investigate the potential hepatoprotective effects of F. parviflora extract on vincristine induced toxicity in adult male rats. Materials and methods: In this experimental study, the rats (n=42) were divided into 7 groups: 1) Sham group, 2) vehicle group, 3) vincristine group (VCR) (0.5 mg/kg, i.p.), 4) F. parviflora extract (300 mg/kg, p.o.), 5) F. parviflora extract (500 mg/kg, p.o.), 6) Pretreatment group: F. parviflora extract (300mg/kg for 10 days, p.o.) + VCR (0.5 mg/kg, i.p.) on 9th and 10th days of the experiment, and 7) Pretreatment group: F. parviflora extract (500mg/kg for 10 days, p.o.) +VCR (0.5 mg/kg, i.p.) on 9th and 10th days of the experiment. Serum values of AST, ALT, ALP and malondialdehyde (MDA) were measured. Data were analyzed by one way ANOVA using prism software. Results: F. parviflora extract with dose of 500 mg/kg markedly decreased ALT hepatic enzyme level caused by vincristine (P<0.01). In addition, the dose of 300 mg/kg could not decrease the elevated liver enzymes, including ALP, ALT and AST and also MDA levels.

Therefore, it is attempted to substitute antibiotics with natural products, such as nanoparticles and plant extracts. The aim of this study was to investigate the synergistic antibacterial effects of silver nanoparticles with extracts of nettle and shallot plants against multi drug resistant (MDR) kebsiella. Materials and methods: Of 360 clinical samples, 112 kebsiella were isolated from ICU hospitalized patients. The klebsiella isolates were identified by biochemical tests. The antibiotic susceptibility of isolates was determined using disc diffusion method. Minimum inhibitory concentration of silver nanoparticles, nettle and shallot extracts against resistant isolates was assessed by broth microdilution method and their synergitic effects were determined using checkerboard method. Also the fractional inhibition concentration (FIC) was calculated. Results: The silver nanoparticles were more effective than plant extracts against MDR isolates. The use of silver nanoparticles and shallot extract together led to synergistic effect on both MDR klebsiella isolate and Klebsiella pneumoniae ATCC 1290. In addition, the use of the silver nanoparticles and nettel extract led to synergistic effect on MDR isolate of klebsiella and additive effect ATCC isolate. Conclusion: Due to good antibacterial effect of AgNPs, shallot and nettle extracts on resistant klebsiella isolates and their affordable production, they can be exploited in addition to antibiotic treatments.

Interleukins are a group of cytokine which are produced through T cells, monocytes, macrophages, and endothelial cells. Interleukin-10 is an important multitasking cytokine that has a key role in inflammatory responses. The promoter of interlekin-10 is highly polymorphic and many of its polymorphisms were identified. The purpose of this study was to investigate and detect the A1082G and T819C polymorphisms of interleukin-10 promoter in ulcerative colitis patients. Materials and methods: In this case- control study, DNA from 150 individuals with ulcerative colitis and 150 controls were determined by PCR technique. Data were analyzed by Chi-square test using SPSS software. Also, odds ratios and 95% confidence interval were calculated. Results: The results showed that distribution of GG and CC genotypes and frequency of G and C alleles (related to A1082C and T819C polymorphisms, respectively) was significantly different between patient and control groups. Conclusion: According to the results, both polymorphisms of IL-10 gene promoter (A1082G and T819C), including G allel and C allel, respectively, are likely to be considered as risk factors for ulcerative colitis. Moreover, both genotype of GG and CC can increase the incidence of ulcerative colitis.

Colon bacteria, including Klebsiella pneumonia, are the main cause of urinary tract infections. The occurrence of the antibiotic resistance is a major problem in the treatment of infections. Beta- lactamases and efflux pumps constitute the major defense mechanisms of antibiotic resistance of Klebsiella pneumoniae. The aim of present study was to detect oqxA and oqxB genes that encoding oqxAB efflux pumps, in the resistant strains of Klebsiella pneumoniae. Materials and methods: Among 430 urine samples gathered from Mofoid and Modares Hospitals and Farabi Tajrish Laboratory, 100 strains of Klebsiella pneumoniae has been isolated. Antibiotic sensitivity tests have been accomplished by disc diffusion method based on CLSI standard. The ESBL strains have been identified by Roscoe's compound discs. Finally, the presences of oqxAB efflux pumps have been detected by PCR method through finding the genes encoding these pumps. Results: Among 100 Klebsiella pneumoniae strains, 43% were ESBL positive. Imipenem, piperacillin tazobactam and morphenem were identified more effective than other antibiotics. The prevalence of oqxA and oqxB genes among resistant isolates was 69.76% and 72.1%, respectively. Conclusion: Regarding our findings, the urinary tract infections caused by Klebsiella pneumoniae were more prevalent in hospitalized patients. As well as, it was shown a higher percentage of resistance in compare with strains isolated from outpatients. Since the high resistance of Klebsiella pneumoniae strains is very worrying, antibiotics prescribing especially carbapenems need to be strongly supervised.
