Contovir - A new adjuvant therapy in recurrent respiratory papillomatosis: A case study

Background: Contovir is a mixture of herbal extracts (Tanacetum vulgare, Rossa canina, Urtica dioica) that is supplemented with selenium. Objectives: This study aimed to add Contovir to the classic treatment of recurrent respiratory papillomatosis (RRP) in order to decrease the severity and extent of the disease, elongate the surgical intervals and improve the sense of patient well-being. Furthermore, we had to adjust the prescribed drug dosage, since there were no previous findings available. Patients and Methods: This is a case study of RRP patients treated with Contovir as an adjuvant to the classic treatment, from March 2011 to February 2013, at an academic tertiary hospital (Rasoul-e-Akram hospital). All patients underwent surgical removal of papilloma and then were prescribed Contovir. Disease severity was quantified based on Derkay�s staging system. Results: Eight patients were enrolled in this study. The extent and severity of the disease improved in six cases. One had no response, and the severity of disease increased in one patient. Patients with supraglottic lesions had better responses to Contovir adjuvant therapy. No immediate or long-term side effects were reported. Conclusions: Although Contovir has been found to be an advantageous adjuvant for RRP treatment, further studies are called for to verify these findings. © 2016, Iranian Red Crescent Medical Journal

Iranome: A catalogue of genomic variations in the Iranian population

Considering the application of human genome variation databases in precision medicine, population-specific genome projects are continuously being developed. However, the Middle Eastern population is underrepresented in current databases. Accordingly, we established Iranome database (www.iranome.com) by performing whole exome sequencing on 800 individuals from eight major Iranian ethnic groups representing the second largest population of Middle East. We identified 1,575,702 variants of which 308,311 were novel (19.6%). Also, by presenting higher frequency for 37,384 novel or known rare variants, Iranome database can improve the power of molecular diagnosis. Moreover, attainable clinical information makes this database a good resource for classifying pathogenicity of rare variants. Principal components analysis indicated that, apart from Iranian-Baluchs, Iranian-Turkmen, and Iranian-Persian Gulf Islanders, who form their own clusters, rest of the population were genetically linked, forming a super-population. Furthermore, only 0.6% of novel variants showed counterparts in "Greater Middle East Variome Project", emphasizing the value of Iranome at national level by releasing a comprehensive catalog of Iranian genomic variations and also filling another gap in the catalog of human genome variations at international level. We introduce Iranome as a resource which may also be applicable in other countries located in neighboring regions historically called Greater Iran (Persia)

Dyads of GGC and GCC form hotspot colonies that coincide with the evolution of human and other great apes

Abstract Background GGC and GCC short tandem repeats (STRs) are of various evolutionary, biological, and pathological implications. However, the fundamental two-repeats (dyads) of these STRs are widely unexplored. Results On a genome-wide scale, we mapped (GGC)2 and (GCC)2 dyads in human, and found monumental colonies (distance between each dyad < 500 bp) of extraordinary density, and in some instances periodicity. The largest (GCC)2 and (GGC)2 colonies were intergenic, homogeneous, and human-specific, consisting of 219 (GCC)2 on chromosome 2 (probability < 1.545E-219) and 70 (GGC)2 on chromosome 9 (probability = 1.809E-148). We also found that several colonies were shared in other great apes, and directionally increased in density and complexity in human, such as a colony of 99 (GCC)2 on chromosome 20, that specifically expanded in great apes, and reached maximum complexity in human (probability 1.545E-220). Numerous other colonies of evolutionary relevance in human were detected in other largely overlooked regions of the genome, such as chromosome Y and pseudogenes. Several of the genes containing or nearest to those colonies were divergently expressed in human. Conclusion In conclusion, (GCC)2 and (GGC)2 form unprecedented genomic colonies that coincide with the evolution of human and other great apes. The extent of the genomic rearrangements leading to those colonies support overlooked recombination hotspots, shared across great apes. The identified colonies deserve to be studied in mechanistic, evolutionary, and functional platforms

Novel extreme homozygote haplotypes at the human caveolin 1 gene upstream purine complex in sporadic Alzheimer's disease.

Item does not contain fulltextAberrant expression of the caveolin-1 (CAV1) gene is associated with Alzheimer's disease (AD) brain. We have recently reported a polymorphic purine stretch located at between 1.8 and 1.5 kb flanking the CAV1 gene, whose alleles and genotypes are associated with late-onset AD. Extra-short homozygote haplotypes were observed that were present only in the AD cases. Following an independent case/control study, we report alleles at the other extreme of the allele range, haplotypes of which were observed to be homozygous across the region in the AD cases. We propose that there is a window for the length of motifs and haplotypes in the controls. Homozygosity for shorter and longer motifs and haplotypes was linked with AD in our study. Our findings elucidate novel predisposing haplotypes at the CAV1 gene purine complex, and confirm the role of this region in the etiopathophysiology of late-onset AD
