UNLABELLED: Venous thromboembolism (VTE) is one of the most common complications in cancer patients. Although factor V Leiden (FVL) is the most common genetic defect causing thrombosis, the impact of gene abnormalities on thrombotic tendency in cancer patients remains poorly explored. Tissue factor (TF) is a major physiologic initiator of blood coagulation. This is the first study regarding the association of TF gene -603A/G and +5466A>G polymorphisms with VTE in malignancy. Materials and Me-thods: The study consists of two groups: cancer patients with VTE were included as Group 1 (n = 46); Group 2 comprises 196 cancer patients without VTE...

Crohn's Disease is one of the two major forms of the Inflammatory Bowel Diseases and, although the etiology is not completely understood, the confluence of environmental and genetic factors has been demonstrated. The aim of this study was to determine the distribution of TLR4 variants in a Spanish cohort of Crohn's Disease patients and their relation with phenotype and common NOD2 variants. A total of 371 Crohn's Disease (CD) patients and 636 healthy controls (HC) were included. Single Nucleotide Polimorphisms (SNPs) in TLR4 (D299G and T399I) and NOD2 (R702W and G908R) detection was performed by a Taqman(®) Allelic Discrimination Assay...

The HIV-1 subtype C has been substituting the subtype B population in southern Brazil. This phenomenon has been previously described in other countries, suggesting that subtype C may possess greater fitness than other subtypes. The HIV-1 long-terminal repeat (LTR) is an important regulatory region critical for the viral life cycle. Sequence insertions immediately upstream of the viral enhancer are known as the most frequent naturally occurring length polimorphisms (MFNLP). Previous reports demonstrated that the MFNLP could lead to the duplication of transcription factor binding sites (TFBS) enhancing the activity of the HIV-1 subtype C LTR...

Electrocardiography is a method which can not be replaced by any other examination in arrhythmias. It also plays a crucial role in the diagnosis of arrhythmic rare diseases by providing not only diagnostic data, but also paving the way for treatment. This article presents some characteristic examples of ECG in arrhythmic rare diseases (i.e., polimorphic ventricular tachycardia, Brugada syndrome, Coumela syndrome, nonreentrant supraventricular tachycardia with double ventricular response).

BACKGROUND: Several reports suggest that the reelin protein could play a role in Alzheimer pathophysiology. This led us to ask whether genetic variability in the reelin pathway may increase the risk of developing Alzheimer disease (AD) or mild cognitive impairment (MCI). METHODS: This was a case-control study in which neuropsychological tests were administered and peripheral blood samples taken. The study included 121 patients with AD, 94 with MCI, and 198 controls...

The aim of this paper is to provide a systematic review of the role of the genetic factors, detoxication systems and oxidative stress in the pathogenesis of endometriosis and infertility. Endometriosis and infertility are still both the most uncommon diseases in gynecology. Many aspects of female reproductive function are strongly influenced by genetic factors, and numerous studies have attempted to identify susceptibility genes for disorders affecting female fertility such as polycystic ovary syndrome, endometriosis, fibroids, cancer (ovarian, vulvar, cervical), premature ovarian failure, recurrent pregnancy loss and pre-eclampsia...

The sudden infant death syndrome (SIDS) is the main cause of postneonatal infant death, being defined as the sudden death of an infant under one year of age that remains unexplained after a complete clinical review, autopsy and death scene investigation. The neurotransmitter serotonin (5-HT) is involved in the regulation of a broad array of behavioral and biological functions. By controlling the reuptake of 5-HT from the extracellular space, the serotonin transporter (5-HTT) regulates the duration and strength of the interactions between 5-HT and its receptors...

The incidence and prevalence of diabetes mellitus is globally increasing. The causes of this trend are relatively obvious in the case of type 2 diabetes. In contrast, in case of type 1 diabetes the amount of available data is continuously growing, but the causes are not so well defined. The genetic risk, especially related to the MHC genes is well known, and the increasing amount of data underlines the role of additional risks due to non-MHC genetic polimorphisms. Hopefully, they will provide the basis for future diagnostic and therapeutic approaches...

Brain-derived factor (BDNF) is a member of neurotrophin family and is localized and upregulated in areas implicated in epileptogenesis. Several lines of evidence make the BDNF gene a plausible candidate gene for predisposition to epilepsy. In this study, we tested that BDNF might be involved in the etiology of childhood PE. To assess whether BDNF gene C270T polimorphism could be implicated in vulnerability to PE, we conducted a case-control association analysis (112 partial epileptic and 100 controls) in Turkish children...

22q11.2 deletion syndrome (22q11DS) is a genetic syndrome associated with a microdeletion of the chromosome 22 band q11.2 with an estimated prevalence between 1:2,500 and 1:4,000. Studies of school-age children have shown that individuals with 22q11DS have high rates of psychiatric morbidity. In particular, by late adolescence, about 30% of patients with 22q11DS develop psychotic symptoms. One of the genes located in the microdeletion region of 22q11DS is the Catechol-O-Methyl transferase (COMT) which codes for an enzyme critically involved in the catabolic clearance of dopamine...

Recent findings provide evidence of inflammasome critical role in the predisposition to autoimmune disorders. The involvement of inflammasome in the pathogenesis of systemic lupus erythematosus (SLE) has been hypothesized even if no significant association within inflammasome genes mutations or polymorphisms and lupus has been reported yet. We analyzed 14 single nucleotide polymorphisms (SNPs) within 7 inflammasome genes (NLRP1, NLRP3, NLRC4, AIM2, CARD8, CASP1, IL1B) in 144 patients affected by systemic lupus erythematosus and in 158 healthy controls from Southern Brazilian (state of São Paulo) with the aim of disclosing the possible role of inflammasome genes in the susceptibility of SLE...
