Wild birds are considered as a reservoir for avian chlamydiosis posing a potential infectious threat to domestic poultry and humans. Analysis of 894 cloacal or fecal swabs from free-living birds in Poland revealed an overall Chlamydiaceae prevalence of 14.8% (n = 132) with the highest prevalence noted in Anatidae (19.7%) and Corvidae (13.4%). Further testing conducted with species-specific real-time PCR showed that 65 samples (49.2%) were positive for C. psittaci whereas only one was positive for C. avium. To classify the non-identified chlamydial agents and to genotype the C...

Metronidazole is a first-line drug for the treatment of human infections caused by anaerobic bacteria. Although most Clostridium perfringens isolates are susceptible to metronidazole, a number of strains with decreased susceptibility have been obtained in clinical and environmental surveys. However, little is known yet about the toxinotype and genetic diversity of metronidazole-resistant C. perfringens strains. We tested for susceptibility to metronidazole and assessed the toxigenic status and amplified fragment length polymorphism (AFLP) diversity of a collection of 80 C...

Breast cancer is the most common cancer in women and is the second most common cause of cancer-related death. Despite the relatively high prevalence of this disease, breast cancer manifestations in the head and neck are relatively rare. Supraclavicular lymphadenopathy and bony metastases to the mandible and maxilla are the most common manifestation of breast cancer in the head and neck. Head and neck metastases are the first presentation of distant disease in approximately one-third of cases. The prognosis of breast cancer with distant metastases to the head and neck is generally poor, and the management of these lesions is controversial...

Behavioural anomalies suggesting an inner ear disorder were observed in a colony of transgenic mice. Affected animals were profoundly deaf. Severe hair bundle defects were identified in all outer and inner hair cells (OHC, IHC) in the cochlea and in hair cells of vestibular macular organs, but hair cells in cristae were essentially unaffected. Evidence suggested the disorder was likely due to gene disruption by a randomly inserted transgene construct. Whole-genome sequencing identified interruption of the SorCS2 (Sortilin-related VPS-10 domain containing protein) locus...

MicroRNA is a class of noncoding RNAs able to base pair with complementary messenger RNA sequences, inhibiting their expression. These regulatory molecules play important roles in key cellular processes including cell proliferation, differentiation and response to DNA damage; changes in miRNA expression are a common feature of human cancers. To gain insights into the mechanisms involved in breast cancer progression we conducted a microRNA global expression analysis on a 21T series of cell lines obtained from the same patient during different stages of breast cancer progression...

CIC-DUX4 gene fusion, resulting from either a t(4;19) or t(10;19) translocation, is the most common genetic abnormality detected in EWSR1-negative small blue round cell tumors. Following their discovery it was debated if these tumors should be classified as variants of Ewing sarcoma (ie, atypical Ewing sarcoma) or as a stand-alone pathologic entity. As such the WHO classification temporarily grouped the CIC-rearranged tumors under undifferentiated sarcomas with round cell phenotype, until further clinical evidence was available...

Behavioral and psychological symptoms of dementia often lead to the prescription of antipsychotics, especially in nursing homes, but their use remains controversial. This study aimed to assess antipsychotic drug use in residents with dementia compared with those without dementia. Data were obtained through the cross-sectional 'inappropriate medication in patients with renal insufficiency in nursing homes' (IMREN) study including data from 21 nursing homes. Descriptive statistics were used and factors associated with the prescription of antipsychotics were identified by logistic regression...

NANOG, as a key regulator of pluripotency and acting synergistically with other factors, has been described as a crucial transcription factor in various types of cancer. In meningiomas the expression of this marker has not yet been described. With our study, we aimed to identify and localize Nanog and other possible markers of pluripotency, stem cell properties and differentiation in meningioma tissue, to elucidate a possible effect on tumorigenesis. The gene expression levels of NANOG (NANOG1 and NANOGP8), SOX2, OCT4, KLF4, ABCG2, CMYC, MSI1, CD44, NOTCH1, NES, SALL4B, TP53 and EPAS1 were quantitatively examined using RT-qPCR in 33 surgical specimens of low- (WHO grade I) as well as in atypical and anaplastic (WHO grade II/III) meningiomas with dural tissue as reference...

Carrots are widely grown and enjoyed around the world. Purple carrots accumulate rich anthocyanins in the taproots, while orange, yellow, and red carrots accumulate rich carotenoids in the taproots. Our previous studies indicated that variation in the activity of regulatory genes may be responsible for variations in anthocyanin production among various carrot cultivars. In this study, an R2R3-type MYB gene, designated as DcMYB6, was isolated from a purple carrot cultivar. In a phylogenetic analysis, DcMYB6 was grouped into an anthocyanin biosynthesis-related MYB clade...

Transcription complexes that assemble at the HIV-1 promoter efficiently initiate transcription but generate paused RNA polymerase II downstream from the start site. The virally encoded Tat protein hijacks positive transcription elongation factor b (P-TEFb) to phosphorylate and activate this paused polymerase. In addition, Tat undergoes a series of reversible post-translational modifications that regulate distinct steps of the transcription cycle. To identify additional functionally important Tat cofactors, we performed RNAi knockdowns of sixteen previously identified Tat interactors and found that a novel E3 ligase, PJA2, ubiquitinates Tat in a non-degradative manner and specifically regulates the step of HIV transcription elongation...

Pityriasis rosea (PR) is an acute self-limited exanthem characterized by oval erythematous patches with scale and may be difficult to differentiate from secondary syphilis. A rapid plasma reagin (RPR) test can be used to rule in secondary syphilis with high sensitivity and specificity. A retrospective study was performed on patients at Weill Cornell Medicine, who were diagnosed with PR from 2000 to 2016 and also received RPR testing at the time of diagnosis. The objective was to assess the frequency of secondary syphilis when the initial clinical impression was PR...

Duchenne muscular dystrophy (DMD) is a lethal, X-linked, muscle-wasting disorder caused by mutations in the large, 2.4-Mb dystrophin gene. The majority of DMD-causing mutations are sporadic, multi-exon, frameshifting deletions, with the potential for variable immunological tolerance to the dystrophin protein from patient to patient. While systemic gene therapy holds promise in the treatment of DMD, immune responses to vectors and transgenes must first be rigorously evaluated in informative preclinical models to ensure patient safety...
