1. Effect of crosstalk between Th17 and Th9 cells on the activation of dermal vascular smooth muscle cells in systemic scleroderma and regulation of tanshinone IIA
Abstract Background: To evaluate the effect of T-helper 17 (Th17) cells and Th9 cells on the activation of dermal vascular smooth muscle cells (DVSMCs) in systemic scleroderma (SSc) and regulation of tanshinone IIA. Methods: The expression of interleukin 17 receptor (IL-17R) and interleukin 9 receptor (IL-9R) in the skin of SSc patients was assessed by imm

2. A novel effective method for the assessment of microvascular function in male patients with coronary artery disease: a pilot study using laser speckle contrast imaging
Evaluation of microvascular endothelial function is essential for investigating the pathophysiology and treatment of cardiovascular and metabolic diseases. Although laser speckle contrast imaging technology is well accepted as a noninvasive methodology for assessing microvascular endothelial function, it has never been used to compare male patients with coro

3. Characterization of laser Doppler signal fluctuations in microvascular flow / Caracterização das flutuações do sinal laser doppller do fluxo microvascular
The laser Doppler flow signal from the skin (LDFS) has low-frequency fluctuations which are related to microvascular mechanisms of flow control. The Fourier and the wavelet spectral analysis has been used to correlate fluctuations in the LDFS with the metabolic, metabolic NO-dependent, neurogenic and myogenic mechanisms of control in the frequency intervals

4. Expression of the chemokine receptor CXCR4 on lymphocytes of leprosy patients
Leprosy is caused by Mycobacterium leprae, which induces chronic granulomatous infection of the skin and peripheral nerves. The disease ranges from the tuberculoid to the lepromatous forms, depending on the cellular immune response of the host. Chemokines are thought to be involved in the immunopathogenesis of leprosy, but few studies have investigated the e

5. Repeatability of the evaluation of systemic microvascular endothelial function using laser doppler perfusion monitoring: clinical and statistical implications
OBJECTIVE: An awareness of the repeatability of biological measures is required to properly design and calculate sample sizes for longitudinal interventional studies. We investigated the day-to-day repeatability of measures of systemic microvascular reactivity using laser Doppler perfusion monitoring. METHODS: We performed laser Doppler perfusion monitoring

6. Effects of buflomedil and pentoxifylline on hamster skin-flap microcirculation: prediction of flap viability using orthogonal polarization spectral imaging
OBJECTIVE: This study investigated the effects of buflomedil and pentoxifylline, both of which are used in reconstructive surgery of hamster skin flap microcirculation, and evaluated the skin flap survival rate by orthogonal polarization spectral imaging. METHOD: Twenty-four adult male Syrian golden hamsters were divided into three groups: a control (C, 0.1

7. Basophils activation profile and evidence of histamine release factor in Chronic Idiopathic Urticaria / Perfil de ativação de basófilos e evidência de fatores liberadores de histamina na urticária crônica idiopática
INTRODUCTION: Chronic Urticaria is characterized by recurrent, transitory, pruritic and erythematous wheals present for at least six weeks. In most patients the cause is unknown, defined as idiopathic (CIU), however, a sub-group has autoantibodies against the alfa chain of the high affinity IgE receptor (FceRIa) expressed on mast cells and basophils surface

8. Effects of chronic and prolonged solar radiation in immunologic system of fishermen from Recife, Brazil / Efeitos da radiação solar crônica e prolongada sobre o sistema imunológico de pescadores do Recife
Introduction: The ultraviolet radiation effects on the human immunological system are highly complex, disturbing some components of immune response. Objective: The objective of this study was to evaluate the clinical, histopathological and immunological effects from solar radiation in male fishermen with more than 10 years of uninterrupted activity. Methods:

9. Perfil laboratorial bioquÃmico e hematolÃgico de uma populaÃÃo de pacientes diagnosticados com hansenÃase: antes e durante a poliquimioterapia
Leprosy or Hansenâs disease is an infectious disease with slow flow velocity, transmitted by Mycobacterium leprae that attacks nerves and skin. The specific treatment for people who suffer of leprosy was emphasized in the beginning of the 80âs by the World Health Organization (WHO) in order to cure the infection with Mycobacterium leprae and prevent disabi

10. Envolvimento do oxido nitrico nas respostas edematogenicas e espasmogenicas induzidas pela bradicinina e histamina
No synthesized from L-arginine, is responsible for various biological effects including oedema formation by plasma protein extravasation (PPE). PPE responses have been measured using local accumulation of intravenously injected 1251-human serum albumin and blood flow by means of a multiple 133 Xenon (Xe) technique in guinea pig skin. L-NAME reduced responses

11. Fluctuations in blood flow to acral skin in humans: connection with heart rate and blood pressure variability.
1. Spontaneous fluctuations in blood flow in arteries supplying acral skin were investigated with Doppler ultrasound in human subjects. Finger blood pressure, heart rate (HR) and cardiac output were measured simultaneously and noninvasively. 2. Synchronous fluctuations in flow were found in arteries supplying the hands and feet. The fluctuations were larger

12. Naloxone increases blood flow in the human hand.
Intravenous injection of 2 mg naloxone produced a rapid and pronounced rise of blood flow (6.3 +/- 5.0 to 67.0 +/- 15.1 ml min-1 100 ml-1) and skin temperature (28.3 +/- 3.0 to 32.4 +/- 1.2 degrees C) in the finger and hand of seven of ten normal volunteers. In the other three there was only a small response. Skin temperature did not change in either the fac
