We exploited the serial analysis of gene expression (SAGE) libraries and human genome database in silico to correlate the breadth of expression (BOE; housekeep-ing versus tissue-specific genes) and peak rate of expression (PRE; high versus low expressed genes) with the density distribution of the retroelements. The BOE status is linearly associated with the density of the sense Alus along the 100 kb nucleotides region upstream of a gene, whereas the PRE status is inversely correlated with the density of antisense L1s within a gene and in the up- and downstream regions of the 0-10 kb nucleotides. The radial distance of intranuclear position, which is known to serve as the global domain for transcription regulation, is reciprocally correlated with the fractions of Alu (toward the nuclear center) and L1 (toward the nuclear edge) elements in each chromosome. We propose that the BOE and PRE statuses are related to the reciprocal distribution of Alu and L1 elements that formulate local and global expression domains.

Anaplasma species are obligate intracellular pathogens that can cause tick-borne diseases in mammalian hosts. To date, very few studies of their occurrence in Korean native goats (Capra aegagrus hircus) have been reported. In the present study, we investigated Anaplasma infection of Korean native goats on Jeju Island, Republic of Korea, and performed phylogenetic analysis based on the 16S rRNA gene sequences. Our results showed that Anaplasma infection was found mostly in adult female goats. The phylogenetic tree revealed that the 7 sequences identified in Korean native goats could belong to Anaplasma sp. and were distinct from A. marginale, A. centrale, and A. ovis. The results indicated that the sequences identified to belong to Anaplasma were closely related to sequences isolated from goats in China and were clustered within the same group. To our knowledge, this is the first study to detect Anaplasma sp. infection in Korean native goats.

OBJECTIVE: To gain basic information regarding the biologic stability of plasma ion-implanted miniscrews and their potential clinical applications. METHODS: Sixteen plasma ion-implanted and 16 sandblasted and acid-etched (SLA) miniscrews were bilaterally inserted in the mandibles of 4 beagles (2 miniscrews of each type per quadrant). Then, 250 - 300 gm of force from Ni-Ti coil springs was applied for 2 different periods: 12 weeks on one side and 3 weeks contralaterally. Thereafter, the animals were sacrificed and mandibular specimens including the miniscrews were collected. The insertion torque and mobility were compared between the groups. The bone-implant contact and bone volume ratio were calculated within 800 microm of the miniscrews and compared between the loading periods. The number of osteoblasts was also quantified. The measurements were expressed as percentages and analyzed by independent t-tests (p < 0.05). RESULTS: No significant differences in any of the analyzed parameters were noted between the groups. CONCLUSIONS: The preliminary findings indicate that plasma ion-implanted miniscrews have similar biologic characteristics to SLA miniscrews in terms of insertion torque, mobility, bone-implant contact rate, and bone volume rate.

Microdeletion of 9q22.3 is a rare chromosomal disorder characterized by body overgrowth, facial dysmorphic features and psychomotor delay. The presence of genomic microdeletion or microdu-plication can not be identified by the conventional chromosomal analysis. Microarray comparative genomic hybridization (CGH) is a newly developed molecular cytogenetic technique that enables the identification of minute copy number variation (CNV) in the human genome. Here, we report a case of microdeletion in the 9q22.31-q22.33 region, which included a patched homolog 1 (PTCH1) gene, as detected by CGH and confirmed by fluorescence in situ hybridization (FISH) analyses in a neonate with prenatal onset of macrosomia, dysmorphism, and muscle hypotonia. To the best of our knowledge, this is the first case report of 9q22.3 microdeletion detected by CGH in Korea.

We report a case of pityriasis versicolor atrophicans in a 20-year-old woman who presented with chronic multiple brownish atrophic macules and patches on chest and back. The lesions had developed six years ago and the patient had used topical medication including steroid ointments for the last two years prior to visiting our clinic. KOH examination was positive, so skin biopsy was performed and the diagnosis of pityriasis versicolor atrophicans was made. Since our patient had applied topical steroids for some time, it was difficult to rule out steroid-induced atrophy in a common tinea versicolor. Also, differential diagnosis was performed with respect to other skin diseases manifesting with cutaneous atrophy including anetoderma.
