[Ti] Title: The Zebrafish Orthologue of the Dyslexia Candidate Gene DYX1C1 Is Essential for Cilia Growth and Function. [So] Source: PLoS One;8(5):e63123, 2013. [Is] ISSN: 1932-6203 [Cp] Country of publication: United States [La] Language: eng [Ab] Abstract: DYX1C1, a susceptibility gene for dyslexia, encodes a tetratricopeptide repeat domain containing protein that has been implicated in neuronal migration in rodent models. The developmental role of this gene remains unexplored. To understand the biological function(s) of zebrafish dyx1c1 during embryonic development, we cloned the zebrafish dyx1c1 and used morpholino-based knockdown strategy. Quantitative real-time PCR analysis revealed the presence of dyx1c1 transcripts in embryos, early larval stages and in a wide range of adult tissues. Using mRNA in situ hybridization, we show here that dyx1c1 is expressed in many ciliated tissues in zebrafish. Inhibition of dyx1c1 produced pleiotropic phenotypes characteristically associated with cilia defects such as body curvature, hydrocephalus, situs inversus and kidney cysts. We also demonstrate that in dyx1c1 morphants, cilia length is reduced in several organs including Kupffer's vesicle, pronephros, spinal canal and olfactory placode. Furthermore, electron microscopic analysis of cilia in dyx1c1 morphants revealed loss of both outer (ODA) and inner dynein arms (IDA) that have been shown to be required for cilia motility. Considering all these results, we propose an essential role for dyx1c1 in cilia growth and function.

[Is] ISSN: 1319-6138 [Cp] Country of publication: Saudi Arabia [La] Language: eng [Ab] Abstract: We report a case of echinococcal disease affecting the brain and the kidney. The case is unusual because of multiplicity of the intracerebral lesion and sparing of the liver and lungs. The intracerebral lesion was presented with epileptic convulsions. This was successfully treated surgically. Subsequently renal echinococcal cysts were identified. These were treated by partial nephrectomy due to the location of the cysts. The patient is disease free at 8 years. [Pt] Publication type: JOURNAL ARTICLE [Em] Entry month: 1305 [St] Status: In-Data-Review

[Ti] Title: Do invasive bullfrogs in Victoria, British Columbia, Canada, show evidence of parasite release? [So] Source: J Helminthol;87(2):195-202, 2013 Jun. [Is] ISSN: 1475-2697 [Cp] Country of publication: England [La] Language: eng [Ab] Abstract: Few studies have examined vertebrate models of invasive species to explore parasite release as a proposed mechanism through which host species might become invasive. In this study, we examined evidence for parasite release in invasive American bullfrogs (Rana catesbeiana/Lithobates catesbeianus) from five sites in Victoria, British Columbia, Canada. We examined helminth species richness, as well as the prevalence, intensity and abundance of lung and kidney fluke infections. These flukes are expected to impose costs on host survival, growth and reproductive output. We compared measures of these parasite taxa with bullfrogs from Ontario and New Brunswick where they are endemic. Helminth species richness in bullfrogs from the Victoria sites was lower than in Ontario bullfrogs, but comparable to reported indices for other endemic populations. The prevalence of lung flukes (Haematoloechus spp.) in bullfrogs from Victoria was twice as high as was observed in the Ontario bullfrogs, and higher than has been reported from other endemic locations. In four of the five study sites in Victoria, numbers of Echinostoma spp. kidney cysts were lower than observed in endemic populations; however, the fifth site had uncharacteristically high numbers of cysts. In this study, there did not appear to be clear evidence to support parasite release using either parasite species numbers, or infection by specific parasite taxa. Instead, the invasive bullfrogs demonstrated high parasite species richness and high levels of infection for parasites known to be harmful to their hosts.

[Ti] Title: Molecular characterization of livestock and human isolates of Echinococcus granulosus from south-west Iran. [So] Source: J Helminthol;87(2):240-4, 2013 Jun. [Is] ISSN: 1475-2697 [Cp] Country of publication: England [La] Language: eng [Ab] Abstract: Hydatidosis is an important public health problem in several parts of Iran. The aim of this molecular study is to investigate Echinococcus granulosus genotypes as the causative agents of hydatidosis in the south-west of Iran (Khuzestan province). In this study, isolates of 334 hydatid cysts were collected from the liver and lungs of 141 sheep, 104 cattle, 84 goats and 5 human cases. DNA was extracted and examined by nested polymerase chain reaction (PCR) of ribosomal DNA (rDNA) internal transcribed spacer 1 (ITS1) and restriction fragment length polymorphism (RFLP)-PCR. In addition, fragments of genes coding for ITS1 were sequenced. The results of RFLP-PCR analysis revealed the presence of the G1 genotype in all human, cattle, goat and sheep isolates. Furthermore, no camel strain (G6) was detected among all samples in the regions studied. The molecular findings indicate that the predominant genotype involved in E. granulosus transmission in south-west Iran is the common sheep strain (G1 genotype), which occurs in human, cattle, sheep and goat populations. In conclusion, these results may have important implications for hydatid disease control in the areas studied.

[Ti] Title: Crustacean-borne infections with microphallid metacercariae (Digenea: Microphallidae) from focal areas in Meghalaya, north-east India. [So] Source: J Helminthol;87(2):222-9, 2013 Jun. [Is] ISSN: 1475-2697 [Cp] Country of publication: England [La] Language: eng [Ab] Abstract: During a survey of edible Crustacea for recovery of infective stages (metacercariae) of potential helminthozoonoses of trematode origin in north-east India, the crab species Barytelphusa lugubris mansoniana, collected from suspected foci of lungfluke infection in Meghalaya and Assam, was found to harbour metacercarial cysts that were different from the earlier reported infection, in which the lungfluke Paragonimus was confirmed to be implicated. Using morphological criteria, this metacercaria was identified as Microphallus indicus Mukherjee & Ghosh, 1967 of the trematode family Microphallidae. The present study extends the previous work by providing molecular characterization of this parasite using ribosomal internal transcribed spacer regions (rDNA ITS1 and ITS2) and the partial large ribosomal subunit DNA, lsr. These target regions were amplified by polymerase chain reaction (PCR) using trematode universal primers and sequenced. In BLAST analysis the query sequences were found close to members of Microphallidae and closest to the genus Microphallus.

[Ti] Title: Dentigerous cyst with an impacted third molar obliterating complete maxillary sinus. [So] Source: Indian J Dent Res;23(6):833-5, 2012 Nov-Dec. [Is] ISSN: 1998-3603 [Cp] Country of publication: India [La] Language: eng [Ab] Abstract: Dentigerous cyst is the most commonly occurring odontogenic cyst after radicular cyst and accounts for 15% of all true cysts in the jaws. The cyst is more common in mandible than in maxilla. The dentigerous cyst is commonly associated with impacted mandibular third molars. In maxilla, the incidence is rare. Dentigerous cyst in maxillary sinus in association with an impacted third molar is an uncommon entity. We present a case of dentigerous cyst associated with an impacted third molar, completely obliterating the maxillary sinus in a 28-year-old female.

[Ti] Title: Klippel-Feil syndrome associated with a craniocervico-thoracic dermoid cyst. [So] Source: Surg Neurol Int;4(Suppl 2):S61-6, 2013. [Is] ISSN: 2152-7806 [Cp] Country of publication: India [La] Language: eng [Ab] Abstract: BACKGROUND: Uncommonly, Klippel-Feil syndrome (KFS) has been associated with intracranial or spinal tumors, most frequently dermoid or epidermoid cysts. Although the associated dermoid cyst (DC) is usually located in the posterior fossa, isolated upper cervical DC has been reported. Extension from the posterior fossa to the upper cervical spine (C2) has been reported once. We report a rare case of KFS in association with a posterior fossa DC that extended down to the upper thoracic spine and review the current literature. CASE DESCRIPTION: A 47-year-old female with presented cervical myelopathy related to a cranio-cervico-thoracic DC in association with KPS-related cervicothoracic fusion (C2-T6) and thoracic kyphosis. The patient underwent complete tumor resection following sub-occipital craniectomy and C1-C4 cervical laminectomy. The patient exhibited complete resolution of symptoms with no tumor recurrence and no deformity at 6-year follow-up. CONCLUSION: DC should be added to the list of congenital central nervous system abnormalities, which should be sought in patients with KFS. Therefore, the presence of a cystic lesion in the posterior fossa, the craniocervical junction or the anterior cervical spine should suggest the possibility of a DC in patients with KFS. In cases of cranio-cervical DC, the tumor may extend quite far down the spinal column (reaching the thoracic spine), as demonstrated in the present case.

[Ti] Title: Unusual locations of the hydatid cyst: a review from iran. [So] Source: Iran J Med Sci;38(1):2-14, 2013 Mar. [Is] ISSN: 0253-0716 [Cp] Country of publication: Iran [La] Language: eng [Ab] Abstract: Hydatid disease is caused by Echinococcus granulosus and is endemic in many parts of the world, including Iran. This parasitic tapeworm can produce cysts in almost every organ of the body, with the liver and lung being the most frequently targeted organs. However, the cyst tends to appear in different and sometimes unusual body sites in various geographical areas of the world. This review provides information on the reported cases of the unusual body sites of the hydatid cyst from Iran in the last 20 years. A literature search was performed through PubMed, Scopus, Google Scholar, IranMedex, Society Information Display (SID), Magiran, and Irandoc using the keywords of "hydatid cyst and Iran" and "Echinococcus granulosus and Iran", and 463 published cases of the hydatid cyst in unusual body sites from Iran were reviewed, evaluated, and discussed. The most common locations were the central nervous system (brain, spinal cord, and orbit), musculoskeletal system, heart, and kidney, while some less common locations were the spleen, pancreas, appendix, thyroid, salivary gland, adrenal gland, breast, and ovary.

[Ti] Title: Morphological spectrum of pilar cysts. [So] Source: N Am J Med Sci;5(2):124-8, 2013 Feb. [Is] ISSN: 2250-1541 [Cp] Country of publication: India [La] Language: eng [Ab] Abstract: BACKGROUND: Cysts of the skin are one of the commonly excised specimens in the surgical outpatient department. A majority of them being clinically diagnosed as sebaceous cysts, their true nature is only discernible on histopathological examination. Closer examination of the type of keratinization involved will throw light into the exact nature of the cyst. Trichilemmal or Pilar cyst is one such entity, which presents in both a non-neoplastic and neoplastic form. AIMS: The present retrospective observational study was undertaken to find out the incidence of these cysts in surgical pathology practice in a rural hospital and to enlist the various morphological forms that these cysts may take. MATERIALS AND METHODS: The histopathology files were reviewed for a period of 6 years for cases coded as pilar cyst. RESULTS: A total of eight cases (5.75%) were identified, which showed features of trichilemmal differentiation. A single case each of proliferating trichilemmal cyst and malignant proliferating trichilemmal tumors were noted. Most of the cases were seen among females on the scalp. CONCLUSIONS: Trichilemmal tumor is an uncommon histopathological entity. Many of these lesions may be mistakenly diagnosed due to lack of recognition of the unique type of keratinization.
