Comparative analysis of secreted enzymes between the anthropophilic-zoophilic sister species Trichophyton tonsurans and Trichophyton equinum.

Trichophyton tonsurans (TT) and Trichophyton equinum (TE) are two closely related dermatophytes with very different host preferences. This study was designed to examine the genetic and transcript level variations of secreted enzymes between TT and TE. Thirty-one genes representing 10 gene families were selected for comparison and complete genomic and cDNA sequences were elucidated.

3D QSAR study, synthesis, and in vitro evaluation of (+)-5-FBVM as potential PET radioligand for the vesicular acetylcholine transporter (VAChT).

Located in presynaptic cholinergic nerve terminals, the vesicular acetylcholine transporter (VAChT) represents a potential target for quantitative visualization of early degeneration of cholinergic neurons in Alzheimer's disease using PET. Benzovesamicol derivatives are proposed as radioligands for this purpose. We report QSAR studies of vesamicol and benzovesamicol derivatives taking into account the stereoselectivity of the VAChT binding site.

Buschke-Ollendorff syndrome in a three-generation family: influence of a novel LEMD3 mutation to tropoelastin expression.

Buschke-Ollendorff syndrome refers to the concomitant occurrence of connective tissue nevi, composed of elastic fibers in most cases, with osteopoikilosis. This autosomal dominant inherited disorder is caused by mutations in the gene LEMD3 on chromosome 12q14, which induces a rather heterogeneous clinical phenotype. Here, we report on the most proximal germline mutation found to date in the LEMD3 gene, p.

+1040 C/T polymorphism in coding region of thrombin-activatable fibrinolysis inhibitor gene and the risk of idiopathic recurrent fetal loss.

Recurrent fetal loss (RFL) is common health problem affecting up to 5% of women of reproductive age. It has been shown that plasma thrombin-activatable fibrinolysis inhibitor (TAFI) concentrations increase during pregnancy and return to baseline levels soon after delivery. The +1040C/T single nucleotide polymorphism in coding region of TAFI gene is associated with TAFI blood levels.

Measurements included Posttraumatic Diagnostic Scale and the Symptom Check List-90-R.

Obstacles in the diagnostics and therapy of heparin-induced thrombocytopenia.

An immune-mediated, severe, acquired prothrombotic disorder, heparin-induced thrombocytopenia type II (HIT II) occurs in 0.5-5% of patients exposed to unfractionated heparin longer than 5-7 days. Arterial and venous thromboses are induced by HIT II in about 35-50% of patients.

Efficacy and safety of nadroparin and unfractionated heparin for the treatment of venous thromboembolism during pregnancy and puerperium.

Introduction: The optimal treatment of pregnancy associated VTE (venous thromboembolism) has not been established yet.

Objective: The assessment of the efficacy and safety of low molecular weight heparin (LMWH) nadroparin and unfractionated heparin (UFH) used for the treatment of pregnancy and puerperium related VTE. Primary study goals were to analyze the incidence of recurrent VTE (proximal extension or pulmonary thromboembolism), thrombocytopenia, major and minor hemorrhages and skin allergic reactions.

Combined analysis of specific KRAS mutation, BRAF and microsatellite instability identifies prognostic subgroups of sporadic and hereditary colorectal cancer.

Confounding effects of specific KRAS gene alterations on colorectal cancer (CRC) prognosis stratified by microsatellite instability (MSI) and BRAF(V600E) have not yet been investigated. The aim of our study was to evaluate the combined effects of MSI, BRAF(V600E) and specific KRAS mutation (Gly → Asp; G12D, Gly → Asp, G13D; Gly → Val; G12V) on prognosis in 404 sporadic and 94 hereditary CRC patients. MSI status was determined according to the Bethesda guidelines.

The oncology treatment of patients who use oral anticoagulants is connected with high risk of bleeding complications.

The data about risk for bleeding complications during anticoagulation in cancer patients with different oncology treatment are conflicting. To investigate the rate of bleeding in the course of oral anticoagulants, during treatment of malignant diseases, we conducted a retrospective study including 75 patients on stable anticoagulation prior to commencing their different oncology treatment. All patients were treated according to the consiliar decision, made based on the localization and pathohistological findings of the malignant disease.

Thrombophilia in women with pregnancy-associated complications: fetal loss and pregnancy-related venous thromboembolism.

Background/aims: Existing data regarding the prevalence of thrombophilia in women with pregnancy complications are conflicting.

Methods: To investigate the relationship between pregnancy-associated complications and the presence of thrombophilia, we studied the records of 453 women with pregnancy-associated complications. In 55 women, intrauterine fetal death (fetus mortus in utero, FMU) after 20 weeks of gestation was recorded, in 231 two or more consecutive recurrent fetal losses (RFL) were recorded, while 167 had a venous thromboembolism (VTE) during one of their pregnancies.

[Heparin-induced thrombocytopenia occurring after surgical treatment of atrial myxoma--a case report].

Introduction: Heparin-induced thrombocytopenia (HIT) is an acquired, prothrombotic disorder, caused by antibodies to a complex of heparin and platelet factor 4 (PF4) that activates platelets, resulting in the release of procoagulant microparticles, thrombocytopenia occurrence, generation of thrombin, and frequent thromboses.

Case Outline: We present a case of severe HIT in a 68-year-old female, which occurred after cardiosurgery of the left atrial myxoma with the aim to point out the importance of differential diagnosis of thrombocytopenia in patients recently exposed to heparin. Platelet count dropped on the eleventh postoperative day, six days after unfractioned heparin and enoxaparine threatment, to 4x10(9)/I.

Prognostic and predictive value of TOPK stratified by KRAS and BRAF gene alterations in sporadic, hereditary and metastatic colorectal cancer patients.

Background: Our aim was to investigate the prognostic and predictive value of the oncogenic MAPKK-like protein T-cell-originated protein kinase (TOPK) stratified by KRAS and BRAF mutations in patients with sporadic, hereditary and metastatic colorectal cancer (CRC) treated with anti-EGFR therapy.

Methods: Immunohistochemistry (IHC) for TOPK was performed on four study groups. Group 1 included two subgroups of 543 and 501 sporadic CRC patients used to test the reliability of TOPK expression by IHC.

Forensic aspects of alcohol abuse and homicide.

Numerous investigations indicate a close link between violent behavior, homicide (murder) and alcohol intoxication. With increased frequency of drinking and the chronic consummation of alcohol, the risk of the fatal outcome or homicide and victimization caused by violence is more likely to occur. Studies conducted on convicted murderers suggested that about half of them were under the heavy influence of alcohol at the time of perpetration of murder.

The use of D-dimer with new cutoff can be useful in diagnosis of venous thromboembolism in pregnancy.

Objective: D-dimer testing has an important role in the exclusion of acute venous thromboembolism (VTE) in the nonpregnant population. Establishing D-dimers role in the diagnosis of VTE in pregnancy is hampered because of the substantial increase of D-dimer throughout gestational age.

Study Design: In a prospective study we followed 89 healthy pregnant women to establish the reference range of D-dimer for each trimester.

[The c.-1639g > A polymorphism of the VKORC1 gene and his influence on the therapeutic response during oral anticoagulants use].

A comparative study on the role of cytokinins in caryopsis development in the maize miniature1 seed mutant and its wild type.

We report here on a comparative developmental profile of plant hormone cytokinins in relation to cell size, cell number and endoreduplication in developing maize caryopsis of a cell wall invertase-deficient miniature1 (mn1) seed mutant and its wild type, Mn1, genotype. Both genotypes showed extremely high levels of total cytokinins during the very early stages of development, followed by a marked and genotype specific reduction. While the decrease of cytokinins in Mn1 was associated with their deactivation by 9-glucosylation, the absolute and the relative part of active cytokinin forms was higher in the mutant.

Inherited thrombophilia is associated with pregnancy losses that occur after 12th gestational week in Serbian population.

Recurrent fetal loss (RFL) is a significant clinical problem, occurring in 1% to 5% of reproductive females. Inherited or acquired thrombophilia has been diagnosed in 50% to 65% of women with history of unexplained fetal loss. The objective of our study was to determine the prevalence of thrombophilia in women with unexplained RFL in Serbian population and to find out whether the presence of thrombophilia is associated with pregnancy losses that occur later than 12th gestational week.

Flow cytometric immunobead assay for the detection of BCR-ABL fusion proteins in leukemia patients.

BCR-ABL fusion proteins show increased signaling through their ABL tyrosine kinase domain, which can be blocked by specific inhibitors, thereby providing effective treatment. This makes detection of BCR-ABL aberrations of utmost importance for diagnosis, classification and treatment of leukemia patients. BCR-ABL aberrations are currently detected by karyotyping, fluorescence in situ hybridization (FISH) or PCR techniques, which are time consuming and require specialized facilities.

PVY(NTN) elicits a diverse gene expression response in different potato genotypes in the first 12 h after inoculation.

Host gene expression changes in the early response to potato virus Y(NTN) interaction were compared in two differently sensitive potato cultivars: the resistant cultivar Santé and the sensitive cultivar Igor. Hybridization of potato TIGR cDNA microarrays allowed us to monitor the expression of approximately 10,000 genes simultaneously at 0.5 and 12 h post-inoculation (hpi).

Chromotherapy in the regulation of neurohormonal balance in human brain--complementary application in modern psychiatric treatment.

There is evidence that visible electromagnetic spectrum of light we see as colors can have impact on human health, Cicardian rhythm or biological clock is complex fundamental physiological and biological cycle in human organism. The biological clock in humans is located in the specialized group of brain cells called suprachiasmatic nucleus (SCN) within the anterior hypothalamus.

Domestic homicide cases related to schizophrenic offenders.

The goal of this study was identification of highly specific patterns of schizophrenia related domestic homicides by comparing schizophrenic homicide offenders with related domestic homicide group of offenders diagnosed with other psychiatric disorders. This study was based on the comparison of schizophrenic homicide group and other homicide group of offenders on the basis of differences in psychosocial and sociodemographic patterns and the modality of crime. The survey was conducted on mentally insane domestic homicide offenders diagnosed with schizophrenia (n=44) and second group of mentally insane offenders diagnosed with other psychiatric diagnosis (n=43).

Phenolic content and antioxidative capacity of green and white tea extracts depending on extraction conditions and the solvent used.

The efficiencies of different solvents in the extraction of phenolics from bagged and loose leaves of white and green tea, after different extraction times, as well as the antioxidative capacity of the obtained extracts, were investigated. The developed HPLC method has the potential to separate and determinate 17 phenolics widely distributed in plants, but in investigated tea extracts only four catechins and traces of three flavonols and one flavone were separated and detected based on comparison with authentic standards. The extraction efficiency of phenolics depended strongly on the time of extraction and the solvents used.
