The preservative 2-(thiocyanomethylthio)benzothiazole : A potential allergen in leather products

Background: Allergic contact dermatitis caused by leather is common, and several responsible allergens, such as tanning agents, glues, mercaptobenzothiazole derivatives, and dyes, but also antimicrobials and antifungals, are involved. Material and methods: Three female patients were referred to the Departments of Dermatology in a Belgian university hospital following skin reactions caused by leath

De svenska kommunerna i EU:s konstitutionella system

Tidigare forskning har visat hur lokala och regionala organ i EU:s medlemsstateringår i ett system för flernivåstyre (multi-level governance). Frågan för denhär rapporten är vilken ställning de svenska kommunerna har i dennaflernivåorganisation. Inriktningen är juridisk och syftar till att bidra till förståelsenav kommunernas rättsliga roll i dagens statsskick.Att de svenska kommunerna påverkas av

Arrayed molecular barcoding identifies TNFSF13 as a positive regulator of acute myeloid leukemia-initiating cells

Dysregulation of cytokines in the bone marrow microenvironment promotes acute myeloid leukemia cell growth. Due to the complexity and low throughput of in vivo stem-cell based assays, studying the role of cytokines in the bone marrow niche in a screening setting is challenging. Herein, we developed an ex vivo cytokine screen using 11 arrayed molecular barcodes, allowing for a competitive in vivo r

Rare allelic forms of PRDM9 associated with childhood leukemogenesis

One of the most rapidly evolving genes in humans, PRDM9, is a key determinant of the distribution of meiotic recombination events. Mutations in this meiotic-specific gene have previously been associated with male infertility in humans and recent studies suggest that PRDM9 may be involved in pathological genomic rearrangements. In studying genomes from families with children affected by B-cell prec

Lack of association between hemolysin production and acute inflammation in human urinary tract infection

Hemolysins are cytolytic proteins which have been extensively characterized at the molecular level, however, their in vivo functions remain unclear. This study analyzed the association of hemolysin production with the inflammatory response in patients with urinary tract infection (UTI). Infants and children with their first episode of UTI (n = 644) were followed prospectively. The body temperature

Molecular characterization of a plasmid-borne (pGT633) erythromycin resistance determinant (ermGT) from lactobacillus reuteri 100-63

Lactobacillus reuteri 100-63 contains a 9.8 kb plasmid (pGT633) encoding resistance to the macrolide-lincosamide-streptogramin (MLS) type B antibiotics. The restriction endonucleases AccI, BamHI, Bcl I, EcoRI, EcoRV, HhaI, HindII, Hpa I, KpnI, SalI, and SspI were employed to establish a physical map of pGT633. Next, genetic transfer experiments were conducted to establish the host range of pGT633.

Suppressed antibody and interleukin-6 responses to acute pyelonephritis in pregnancy

This study examined the effect of pregnancy on the host response to acute pyelonephritis. Urine and serum samples were obtained at the time of diagnosis and after two weeks, from non-pregnant and pregnant women with acute pyelonephritis. The samples were analyzed for interleukin-6 (IL-6) and specific antibody activity to antigens extracted from the Escherichia coli strain infecting each patient. T

Stereo- And regioselective hydroboration of 1-exo-methylene pyranoses : Discovery of aryltriazolylmethyl C-galactopyranosides as selective galectin-1 inhibitors

Galectins are carbohydrate recognition proteins that bind carbohydrates containing galactose and are involved in cell signaling and cellular interactions, involving them in several diseases. We present the synthesis of (aryltriazolyl)methyl galactopyranoside galectin inhibitors using a highly diastereoselective hydroboration of C1-exo-methylene pyranosides giving inhibitors with fourfold or better

P-fimbriae trigger mucosal responses to Escherichia coli in the human urinary tract

Uropathogenic Escherichia coli elicit a host response that determines the severity of urinary tract infection (UTI). Specific adherence mechanisms allow the bacteria to initiate this process by targeting epithelial cells in the urinary tract mucosa. Epidemiological studies show a strong association of P-fimbriae with disease severity, suggesting that adherence mediated by these organelles has a di

P fimbriae enhance the early establishment of Escherichia coli in the human urinary tract

This study examined the role of P fimbriae in the establishment of bacteriuria. Patients (n = 17) were subjected to intravesical inoculation with an asymptomatic bacteriuria strain, Escherichia coli 83972, or its P-fimbriated (pap+/prs+) transformants. As shown by groupwise analysis, the pap+/prs+ transformants established bacteriuria more rapidly than E. coli 83972 (P = 0.021) and required a lowe

Urodynamic factors influence the duration of Escherichia coli bacteriuria in deliberately colonized cases

Purpose: We evaluated the influence of urodynamic factors on the establishment of bacteriuria, after deliberate intravesical inoculation with Escherichia coli. Materials and Methods: Nine women and 7 men with recurrent symptomatic urinary tract infections underwent intravesical injection of E. coli 83972. This strain had documented ability to persist in the urinary tract and it lacks expressed vir

Animal models of l-dopa-induced dyskinesia in Parkinson's disease

Understanding the biological mechanisms of l-dopa-induced motor complications is dependent on our ability to investigate these phenomena in animal models of Parkinson's disease. The most common motor complications consist in wearing-off fluctuations and abnormal involuntary movements appearing when plasma levels of l-dopa are high, commonly referred to as peak-dose l-dopa-induced dyskinesia. Parki

Competetive microbial exclusion as treatment against complicated lower urinary tract infections

OBJECTIVE: Deliberate colonization of the lower urinary tract has been proposed as treatment against recurrent urinary tract infection - UTI. The bacteria chosen has to be able to colonize the urinary tract for longer periods without causing symptoms, and should be able to prevent manifest superinfections. MATERIALS: Sixteen patients (9 women and 7 males), all having a history of recurrent symptom

Intestinal carriage of p fimbriated escherichia coli and the susceptibility to urinary tract infection in young children

This prospective study analyzed the intestinal carriage of P fimbriated Escherichia coli as a host susceptibility factor in urinary tract infection (UTI). P fimbriation was defined by the pap and G ad hesin (papG1A2prsGJ96)genotypes. Children with UTI carried pap+E. coli in the fecal flora more often than healthy controls both at diagnosis (86% vs. 29%) and during infection-free intervals (40%; P

IDH1 and IDH2 mutations in pediatric acute leukemia

To investigate the frequency of isocitrate dehydrogenase 1 (IDH1) and 2 (IDH2) mutations in pediatric acute myeloid leukemia (AML) and acute lymphoid leukemia (ALL), we sequenced these genes in diagnostic samples from 515 patients (227 AMLs and 288 ALLs). Somatic IDH1/IDH2 mutations were rare in ALL (N=1), but were more common in AML, occurring in 3.5% (IDH1 N=3 and IDH2 N=5), with the frequency h
