Transcriptional activity of the short gastrulation primary enhancer in the ventral midline requires its early activity in the presumptive neurogenic ectoderm.

The short gastrulation (sog) shadow enhancer directs early and late sog expression in the neurogenic ectoderm and the ventral midline of the developing Drosophila embryo, respectively. Here, evidence is presented that the sog primary enhancer also has both activities, with the late enhancer activity dependent on the early activity. Computational analyses showed that the sog primary enhancer contains five Dorsal (Dl)-, four Zelda (Zld)-, three Bicoid (Bcd)-, and no Single-minded (Sim)-binding sites.

The short gastrulation shadow enhancer employs dual modes of transcriptional synergy.

It remains unclear how a limited amount of maternal transcription factor Dorsal (Dl) directs broad expression of short gastrulation (sog) throughout the presumptive neurogenic ectoderm in the Drosophila early embryo. Here, we present evidence that the sog shadow enhancer employs dual modes of transcriptional synergy to produce this broad pattern. Bioinformatics analyses indicated that a minimal enhancer region, systematically mapped in vivo, contains five Dl-, three Zelda (Zld)-, and three Bicoid (Bcd)-binding sites; four of these five Dl-binding sites are closed linked to two Zld- and two Bcd-binding sites.

Midline enhancer activity of the short gastrulation shadow enhancer is characterized by three unusual features for cis-regulatory DNA.

The shadow enhancer of the short gastrulation (sog) gene directs its sequential expression in the neurogenic ectoderm and the ventral midline of the developing Drosophila embryo. Here, we characterize three unusual features of the shadow enhancer midline activity. First, the minimal regions for the two different enhancer activities exhibit high overlap within the shadow enhancer, meaning that one developmental enhancer possesses dual enhancer activities.

Capicua is involved in Dorsal-mediated repression of zerknüllt expression in Drosophila embryo.

The maternal transcription factor Dorsal (Dl) functions as both an activator and a repressor in a context-dependent manner to control dorsal-ventral patterning in the Drosophila embryo. Previous studies have suggested that Dl is an intrinsic activator and its repressive activity requires additional corepressors that bind corepressor-binding sites near Dl-binding sites. However, the molecular identities of the corepressors have yet to be identified.

Pedobacter namyangjuensis sp. nov. isolated from soil and reclassification of Nubsella zeaxanthinifaciens Asker et al. 2008 as Pedobacter zeaxanthinifaciens comb. nov.

A Gram-stain-negative, non-motile, strictly aerobic, yellow-pigmented bacterium, designated strain 5G38(T), was isolated from a field cultivated with Chinese cabbage in Korea. The strain grew at 5-40°C and at pH 6.0-8.

Genetic and phenotypic diversity of carbofuran-degrading bacteria isolated from agricultural soils.

Thirty-seven carbofuran-degrading bacteria were isolated from agricultural soils, and their genetic and phenotypic characteristics were investigated. The isolates were able to utilize carbofuran as a sole source of carbon and energy. Analysis of the 16S rRNA gene sequence indicated that the isolates were related to members of the genera Rhodococcus, Sphingomonas, and Sphingobium, including new types of carbofuran-degrading bacteria, Bosea and Microbacterium.

ZAS3 promotes TNFα-induced apoptosis by blocking NFϰB-activated expression of the anti-apoptotic genes TRAF1 and TRAF2.

ZAS3 is a large zinc finger transcription repressor that binds the ϰB-motif via two signature domains of ZASN and ZASC. A loss-of-function study showed that lack of ZAS3 protein induced accelerated cell proliferation and tumorigenesis. Conversely, gain-of-function studies showed that ZAS3 repressed NFϰB-activated transcription by competing with NFϰB for the ϰB-motif.

Molecular characterization of methicillin-resistant Staphylococcus aureus isolates in Korea.

We used several molecular typing methods to analyze 196 methicillin-resistant Staphylococcus aureus (MRSA) and 139 methicillin-susceptible S. aureus (MSSA) isolates collected between 1996 and 2005. The sequence type 72 MRSA has increased in frequency in the community in the Republic of Korea and in hospitals in recent years.

Acute human immunodeficiency virus syndrome presenting with hemophagocytic lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) has been described in patients with advanced stages of human immunodeficiency virus (HIV) infection, but rarely occurs during the seroconversion stage of acute HIV infection. We report a case of acute HIV syndrome that presented with virus-associated HLH. The patient recovered spontaneously without any immunomodulating therapy.

High-level vancomycin-resistant Staphylococcus aureus isolates associated with a polymicrobial biofilm.

Glycopeptides such as vancomycin are the treatment of choice for infections due to methicillin-resistant Staphylococcus aureus. This study describes the identification of high-level vancomycin-resistant S. aureus (VRSA) isolates in a polymicrobial biofilm within an indwelling nephrostomy tube in a patient in New York.

Antimicrobial susceptibility and clonal relatedness between community- and hospital-acquired methicillin-resistant Staphylococcus aureus from blood cultures.

We compared the antimicrobial resistance and clonal relationships among the community-acquired (CA) and hospital-acquired (HA) methicillin-resistant Staphylococcus aureus (MRSA) strains that were isolated from blood cultures in a university hospital over a 4-year period. A total of 131 MRSA isolates, including 28 CA-MRSA and 103 HA-MRSA strains, were identified; antimicrobial susceptibility testing indicated that the CA-MRSA isolates were more susceptible to erythromycin (21% vs 6%; P=0.02), clindamycin (46% vs 12%; P=0.

Vibrio vulnificus endophthalmitis occurring after ingestion of raw seafood.

A case of maternal tetanus in Korea.

Tetanus is uncommon in Korea due to the introduction of vaccination programs and advances in public health. A case of maternal tetanus occurred on the 9 day postpartum in a 29-yr-old woman, who had not received a 10-yr-booster of tetanus-diphtheria toxoid after receiving the primary series of tetanus-toxoid-containing vaccine. There has hitherto been no reports on maternal tetanus in Korea.

Biofilm production by isolates of Candida species recovered from nonneutropenic patients: comparison of bloodstream isolates with isolates from other sources.

Biofilm production has been implicated as a potential virulence factor of some Candida species responsible for catheter-related fungemia in patients receiving parenteral nutrition. We therefore compared clinical bloodstream isolates representing seven different Candida species to each other and to those from other anatomical sites for the capacity to form biofilms in glucose-containing medium. Potential associations between the capacity to form biofilms and the clinical characteristics of fungemia were also analyzed.
