Microsporum fulvum, an Ignored Pathogenic Dermatophyte: A New Clinical Isolation from Iran

Misidentifying with Microsporum gypseum has for a long time been accounted for less prevalence of the geophilic species, Microsporum fulvum in human dermatophytosis. We describe a new case of infection with the species in an Iranian young man. Direct examination of skin scrapings revealed a tinea corporis, and morphological study of the recovered isolate from the culture resulted in the identification of M. gypseum. However, PCR amplification of ITS1-5.8S rDNA-ITS2 region and subsequent ITS-RFLP and sequencing were indicative of M. fulvum as the true causative agent. To recognize M. fulvum in human infections and to validate the morphologically distinguished isolates of M. gypseum, the genetic-based identification is strongly recommended.

Ourmia melon virus, a virus from Iran with novel properties

A virus associated with a mosaic disease in melons in the Ourmia district in northern Iran was mechanically transmissible to a wide range of test plants but was not transmitted using aphids, the whitefly Trialeurodes vaporariorum or the mite Tetranychus urticae. Its rather stable particles somewhat resembled those of both geminiviruses and alfalfa mosaic virus; they were 18·5 nm in mean width, parallel-sided, and of several discrete lengths, 30 nm and 37 nm being the shortest and commonest lengths. Both ends of all particles were sharply triangular in profile. The particles contained linear single-stranded RNA of three sizes, estimated as 0·91,0·35 and 0·32, all × 10⁶ molecular weight, and two coat proteins of 26·3 and 23·3 × 10³ estimated molecular weight. The virus, named Ourmia melon virus, appears to be the first described representative of a new virus group.

A Cyanobacterial Gene Encoding a Protein with Extensive Homology to Mammalian Phosphoribosylpyrophosphate Synthetase

Phosphoribosylpyrophosphate (PRibPP) is the primary precursor in the biosynthesis of purine and pyrimidine nucleotides. The synthesis of PRibPP is catalysed by a ubiquitous PRibPP synthetase in many organisms. We provide evidence that a cyanobacterium, Synechococcus sp., has a gene encoding a protein with striking homology to mammalian PRibPP synthetases.

Reln,an Allele ofReelerIsolated from a Chlorambucil Screen, Is Due to an IAP Insertion with Exon Skipping

Thereeler Albany2mutation (Reln^rl-Alb2) in the mouse is an allele ofreelerisolated during a chlorambucil mutagenesis screen. Homozygous animals had drastically reduced concentrations ofreelinmRNA, in which an 85-nt exon was absent. At the genomic level, the mutation was shown to be due to an intracisternal A-particle insertion leading to exon skipping. This appears to be the first observation of retrotransposon insertion during chlorambucil mutagenesis.     

A new species of Angelopteromyia Korneyev, 2001 (Diptera,Platystomatidae) from Iran,with the key to the species

Angelopteromyia korneyevi Mohamadzade Namin, sp. n. from Iran is described and figured. The new species is similar to other species of Angelopteromyia in having abdominal spiracles 5 of females not approximated medially, as well as clypeus extended postero-ventrally, antenna shorter than face, and R₁ and R₄₊₅ setulose on dorsal side. It differs from other species of Angelopteromyia by having mostly brown wing with 3 hyaline crossbands and a few hyaline spots, and dark brownish basal and costal cells without hyaline spots.     

Safety,Health, and Environmental Risk Assessment of a Gas Power Plant: A Case Study from Southern Iran

This research was conducted to assess health, safety, and environmental risks of a gas power plant in southern Iran. In order to identify the subject risks of the power plant at operational phase a questionnaire was designed using the Delphi method. The questionnaires were put at the disposal of 99 electricity industry experts. Risk assessment was done using multicriteria decision-making methods such as technique for order of preference by similarity to ideal solution (TOPSIS), entropy, and Eigenvector technique. Following prioritization of risks at each power plant unit, top-priority risks were determined by one-way ANOVA. The obtained results indicated that the risk of working with medium voltage boards with a weight of 0.879 at the power plant's Electricity Unit is the most important safety and health risk in the studied power plant while risk of servicing the unit with fuel of gas weighting 0.807 and delivery of gas fuel with weight of 0.630 in the Exploiting Unit and work on liquid fuel clutch with weight of 0.603 in the Mechanical Unit are the most important environmental risks in the gas power plant. In conclusion, this study concludes that health, safety, and environmental risk assessment can be a structured and used as a systematic approach to plan for environmental protection and personnel health.     

A new Mylabris species from south-eastern Iran and a key to the Iranian species of the nominate subgenus (Coleoptera, Meloidae)

A new species of Mylabris of the nominate subgenus is described and figured. This species is apparently endemic to the south-eastern Iranian province of Kerman and seems to be phenetically very distinct from all other species of this subgenus, primarily because of the unique elytral pattern. A key to the species of the nominate subgenus distributed in Iran is also presented.     

A new spiny, cushion-like Euphorbia (Euphorbiaceae) from south-west Iran with special reference to the phytogeographic importance of local endemic species

Euphorbia acanthodes Akhani is described as a new gypsophilous species from south-west Iran. The affinity, morphological and carpological features, and habitat of the species are discussed. A list of a further 36 interesting endemic species of south-western Iran and adjacent areas is given with notes on their affinities and distribution. These include Centaurea gudrunensis Boiss. & Hausskn., as a new record from Iran. The specific status of Pteropyrum naufelum Al-Khayat is confirmed and it is suggested that P. noëanum Boiss. ex Meisn. is synonymous with P. aucheri Boiss. The biogeographic importance of the so-called 'Persian foothills', and biodiversity conservation status of the area are discussed, together with distribution maps of 12 species. It is concluded that the majority of the endemic species in the southern and south-western parts of Iran are Irano–Turanian or have their origins in the Irano–Turanian region. Therefore, it is questionable to consider the area as part of either the Saharo–Sindian, Sudanian or Sudano–Zambezian regions.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 146 , 107–121.     

Iranotrichia gen. n., a new genus of Scenopinidae (Diptera) from Iran, with a key to window fly genera of the world

An unusual new genus of Scenopinidae, Iranotrichia gen. n., comprising two newly discovered species (Iranotrichia insolita sp. n. and Iranotrichia nigra sp. n.), is described from Iran. Iranotrichia gen. n. are scenopinine window flies with a habitus reminiscent of certain bee fly genera (Bombyliidae), based on colouration and elongate mouthparts and antennae. The phylogenetic placement of this distinctive new genus is discussed and a dichotomous key to world genera is presented. The genus name Kelseyana nom. n. is proposed to replace Caenoneura Kröber, 1924, which was found to be preoccupied by Thomson (1870: 270) (Hymenoptera) and Kirby (1890: 136) (Odonata).     

Mice with Alopecia,Osteoporosis, and Systemic Amyloidosis Due to Mutation in Zdhhc13, a Gene Coding for Palmitoyl Acyltransferase

Protein palmitoylation has emerged as an important mechanism for regulating protein trafficking, stability, and protein–protein interactions; however, its relevance to disease processes is not clear. Using a genome-wide, phenotype driven N-ethyl-N-nitrosourea–mediated mutagenesis screen, we identified mice with failure to thrive, shortened life span, skin and hair abnormalities including alopecia, severe osteoporosis, and systemic amyloidosis (both AA and AL amyloids depositions). Whole-genome homozygosity mapping with 295 SNP markers and fine mapping with an additional 50 SNPs localized the disease gene to chromosome 7 between 53.9 and 56.3 Mb. A nonsense mutation (c.1273A>T) was located in exon 12 of the Zdhhc13 gene (Zinc finger, DHHC domain containing 13), a gene coding for palmitoyl transferase. The mutation predicted a truncated protein (R425X), and real-time PCR showed markedly reduced Zdhhc13 mRNA. A second gene trap allele of Zdhhc13 has the same phenotypes, suggesting that this is a loss of function allele. This is the first report that palmitoyl transferase deficiency causes a severe phenotype, and it establishes a direct link between protein palmitoylation and regulation of diverse physiologic functions where its absence can result in profound disease pathology. This mouse model can be used to investigate mechanisms where improper palmitoylation leads to disease processes and to understand molecular mechanisms underlying human alopecia, osteoporosis, and amyloidosis and many other neurodegenerative diseases caused by protein misfolding and amyloidosis.     

Astragalus sect. Astragalus (Fabaceae) in Iran, complementary notes with a key to the species

Astragalus zarreianus. is described and illustrated from Iran. It belongs to section Astragalus. This new species confined to western part of Iran (Prov. Illam) from only one location. A key to the species of the section known from Iran is prepared. Differences between the section and the closely related sections are discussed. On the basis of some important trends, an informal grouping is undertaken for yellow flower Astragali. Moreover, A. pseudo-orthocarpus is considered as a valid species in this treatment and differences with its closest relatives are described.
