htlv-1 is the causative agent for a neurologic disease named htlv-i- associated myelopathy/tropical spastic paraparesis (ham/tsp). paraparesis of the lower limbs which appears gradually is the most common clinical feature of this disease. it has been shown that the indirect involvement of the nervous system by lymphocytes is more probable than the direct attack of the virus to the neurons. htlv...

BACKGROUND HTLV-1 associated myelopathy (HAM), or tropical spastic paraparesis, is caused by a retrovirus, the human T-cell lymphotropic virus (HTLV). Although patients with HAM and HIV infection have been described, to our knowledge no direct comparison has been made between patients who are HIV positive and suffering from HAM (HHAM) v. those who are HIV negative and suffering from HAM. AIM ...

The human T-lymphotropic virus type I (HTLV-I) causes a chronic inflammatory disorder of the central nervous system termed HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HTLV-I encodes a protein known to activate several host-signaling pathways involved in inflammation, such as the nuclear factor-κB (NF-κB). The contribution of the NF-κB pathway to the pathogenesis of HAM/...

Girón J., Ivorra E., Sánchez A.J., Fernández-Segovia I., Barat J.M., Grau R. (2014): Preliminary study using visible and SW-NIR analysis for evaluating the loss of freshness in commercially packaged cooked ham and Turkey ham. Czech J. Food Sci., 32: 376–383. A non-destructive Vis-NIR spectroscopy (400–1000 nm) method was developed to evaluate the loss of freshness of sliced and commercially pac...

a new approach utilizing newton method and homotopy analysis method (ham) is proposed for solving nonlinear system of equations. accelerating the rate of convergence of ham, and obtaining a global quadratic rate of convergence are the main purposes of this approach. the numerical results demonstrate the efficiency and the performance of proposed approach. the comparison with conventional homoto...

To investigate candidate genes that influence the risk of HTLV-I associated myelopathy/tropical spastic paraparesis (HAM/TSP), we analyzed 6 single nucleotide polymorphisms (SNP) in the interleukin-10 (IL-10) promoter region. METHODS: 280 cases of HAM/TSP patients and 255 HTLV-I seropositive asymptomatic carriers (HCs) from Kagoshima, Japan were studied. All subjects gave written informed conse...

Background: Human T cell lymphotropic virus type I (HTLV-I)-associated myelopa-thy/tropical spastic paraparesis (HAM/TSP) is an inflammatory disease which occurs in less than 2% of HTLV-I -infected individuals. High proviral load, high HTLV-I-specific CD8+ cytotoxic T lymphocyte frequency (CTL) and host genetic factors such as HLA all appear to be associated with HTLV-I infection. Previous stud...

A chronic spastic myelopathy associated with HTLV-I infection (HTLV-I-associated myelopathy: HAM) shows subclinical pulmonary involvement with bronchoalveolar T lymphocytosis. In the present study, we investigated 18 patients with HAM: five HTLV-I carriers without myelopathy and 13 normal control subjects seronegative for HTLV-I to determine if soluble IL-2 receptors (IL-2R), a marker of lympho...

BACKGROUND Human T cell lymphotropic virus type 1 (HTLV-I) can cause tropical spastic paraparesis/HTLV-1 associated myelopathy (TSP/HAM) and adult T cell leukaemia/lymphoma. More recently other diseases such as isolated peripheral polyneuropathy, myopathy, artropathy, and uveitis have been associated with this retrovirus. Only a few uncontrolled studies, without necessary exclusion criteria, ha...
