Antiretroviral therapy (ART) for HIV has led to increased survival of HIV-infected patients. However, tuberculosis (TB) remains the leading opportunistic infection and cause of death among people living with HIV/AIDS (PLWHA). TB has been shown to be a good predictor of virological failure among PLWHA. This study aimed to evaluate the incidence of TB and its consequences among individuals diagnosed with virological failure of HIV. This was a retrospective cohort study involving PLWHA being followed-up in an AIDS reference center in Salvador, Bahia, Brazil...

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease of unknown cause. Absence of specific targets and biomarkers compromise the development of new therapeutic strategies and of innovative tools to stratify patients and assess their responses to treatment. Here, we investigate changes in neuroprotective-neuroinflammatory actions in the spinal cord of SOD1 (G93A) mice, at presymptomatic and symptomatic stages to identify stage-specific biomarkers and potential targets. Results showed that in the presymptomatic stage, there are alterations in both astrocytes and microglia, which comprise decreased expression of GFAP and S100B and upregulation of GLT-1, as well as reduced expression of CD11b, M2-phenotype markers, and a set of inflammatory mediators...

Recent investigations have showed that the functional thermogenic adipocytes are present in both infants and adult humans. Accumulating evidence suggests that the coexistence of classical and inducible brown (brite) adipocytes in humans at adulthood and these adipocytes function to generate heat from energy resulting in reducing body fat and improving glucose metabolism. Human thermogenic adipocytes can be differentiated in vitro from stem cells, cell lines, or adipose stromal vascular fraction. Pre-activated human brite adipocytes in vitro can maintain their thermogenic function in normal or obese immunodeficient mice; therefore, they improve glucose homeostasis and reduce fat mass in obese animals...

AIM: To evaluate novel risk factors and biomarkers of cardiovascular disease in celiac disease (CD) patients compared with healthy controls. METHODS: Twenty adult patients with recent diagnosis of CD and 20 sex, age and body mass index-matched healthy controls were recruited during a period of 12 mo. Indicators of carbohydrate metabolism, hematological parameters and high sensitive C reactive protein were determined. Moreover, lipoprotein metabolism was also explored through evaluation of the lipid profile and the activity of cholesteryl ester transfer protein and lipoprotein associated phospholipase A2, which is also considered a specific marker of vascular inflammation...

Obesity and overweight have become a leading health problem in the world. But we have not yet had any optimal therapy to prevent this health issue. Accumulating evidence suggests that there is existence of functional brown/brite adipocytes in both infants and adult humans, and the activated brown/brite can burn energy by generating heat. These adipocytes can be differentiated from stem cells and transplantation of pre-activated human thermogenic adipocytes in vitro benefits to glucose homeostasis, insulin sensitivity and reduces body fat in normal or obese immunodeficient mice...

Amyotrophic lateral sclerosis (ALS) is a fatal adult-onset neurodegenerative disorder affecting motor neurons (MNs). Evidences indicate that ALS is a non-cell autonomous disease in which glial cells participate in both disease onset and progression. Exosomal transfer of mutant copper-zinc superoxide dismutase 1 (mSOD1) from cell-to-cell was suggested to contribute to disease dissemination. Data from our group and others showed that exosomes from activated cells contain inflammatory-related microRNAs (inflamma-miRNAs) that recapitulate the donor cell...

Browning is the process of increasing the number of brite cells, which helps to increase energy expenditure and reduce obesity. Consumption of natural and non-toxic herbal extracts that possess the browning effect is an attractive anti-obesity strategy. In this study, we examined the browning effect of cinnamon extract. We found that cinnamon extract (CE) induced typical brown adipocyte multiocular phenotype in 3T3-L1 adipocytes. The treatment also increased brown adipocytes markers and reduced white adipocytes markers in the 3T3-L1 adipocytes...

The introduction of highly active antiretroviral therapy marked a major gain in efficacy of HIV/AIDS treatment and a reduction in morbidity and mortality of the infected patients. However, high levels of adherence are required to obtain virologic suppression. In Brazil, the policy of free and universal access to antiretroviral therapy has been in place since 1996, although there are reports of poor adherence. OBJECTIVE: To define the clinical, demographic and psychological characteristics, and quality of life of patients with HIV/AIDS who present poor adherence to highly active antiretroviral therapy...

Persistent immune actiation is associated with innadequate immune recovery in HIV-patients. This study assessed the relationship between frequency of expression of cell activation markers (CD38 and HLADR) and presence of oral lesions in HIV-1 infected patients. Fifty-seven HIV-infected persons, undergoing antiretroviral treatment, were divided into three groups, according to the number of CD4(+) T cells and CD4(+) /CD8(+) ratio: adequate, partial, and inadequate immune restauration. All patients underwent full mouth assessments for saliva flow measurement, oral mucosal lesion, periodontal disease, and severity of periodontitis...

Adipose tissue (AT) is a highly heterogeneous organ. Beside the heterogeneity associated to different tissue types (white, brown and "brite") and its location-related heterogeneity (subcutaneous, visceral, epicardial, and perivascular, etc), AT composition, structure and functionality is highly dependent on individual-associated factors. As such, the pro-inflammatory state associated to the presence of obesity and other cardiovascular risk factors directly affects AT metabolism. Furthermore, the adipose-derived stem cells (ASCs) that reside in the stromal vascular fraction (SVF) of AT, besides being responsible for most of the plasticity attributed to AT, is an additional source of heterogeneity...

Evidence from clinical and experimental data suggests that thyrotropin receptor (TSHR) signaling is involved in energy expenditure through its impact on white adipose tissue (WAT) and brown adipose tissue (BAT). TSHR expression increases during mesenchymal stem cell (MSC) differentiation into fat. We hypothesize that TSHR activation [TSHR*, elevated thyroid-stimulating hormone, thyroid-stimulating antibodies (TSAB), or activating mutation] influences MSC differentiation, which contributes to body composition changes seen in hypothyroidism or Graves' disease (GD)...

Inducing brown adipocytes in white adipose tissues is a promising target to combat obesity and its related disorders in human beings. This goal has been especially encouraged by new important discoveries of human brown adipose tissues. The accumulating evidence confirms the presence of active brown adipocytes, not only in newborns, but also in adult humans. In rodents, there are two populations of the Ucp1-expressing adipocytes with well characterized-thermogenic functions, classical interscapular brown adipocytes and brite/beige adipocytes (brown adipocytes that are induced in white adipose tissues)...

Activation of brown adipose tissue (BAT) in adult humans increase glucose and fatty acid clearance as well as resting metabolic rate, whereas a prolonged elevation of BAT activity improves insulin sensitivity. However, substantial reductions in body weight following BAT activation has not yet been shown in humans. This observation raise the possibility for feedback mechanisms in adult humans in terms of a brown fat-brain crosstalk, possibly mediated by batokines, factors produced by and secreted from brown fat...

OPA1 (Optic Atrophy 1) is a mitochondrial GTPase known to regulate fission of mitochondria. It was recently also shown to locate on lipid droplets in adipocytes where it functions as an A-kinase anchoring protein (AKAP) that mediates adrenergic control of lipolysis by facilitating PKA phosphorylation of perilipin (Plin1). In brown adipocytes indirect evidence support the notion that OPA1 regulation of fission serves to increase thermogenesis, which thereby contributes to dissipation of energy. In white adipocytes, OPA1 located on lipid droplets serves as a gatekeeper to control lipolysis induced by adrenergic agonists...

BACKGROUND: Combination therapy is one of the most effective tools for limiting the emergence of drug resistance in pathogens. Despite the widespread adoption of combination therapy across diseases, drug resistance rates continue to rise, leading to failing treatment regimens. The mechanisms underlying treatment failure are well studied, but the processes governing successful combination therapy are poorly understood. We address this question by studying the population dynamics of Mycobacterium tuberculosis within tuberculosis patients undergoing treatment with different combinations of antibiotics...

Brazilian spotted fever (BSF) is an endemic anthropozoonosis caused by Gram-negative bacteria (Rickettsia rickettsii) that is associated with the risk of human infection by ticks. In the city of Americana, São Paulo (SP), Brazil, there were 12 cases (67% lethal) between 2004 and 2015. This study evaluated the effectiveness of control over tick infestations in an area at risk of BSF, in a field trial on an association of alpha-cypermethrin (3%) and flufenoxuron (3%) (Tenopa(®)) conducted in Americana. The infestation levels of the target species (Amblyomma sculptum and Amblyomma dubitatum) in the field trial were evaluated through acarological surveys (CO2 traps) on days 0, 22, 43 and 62 after treatment, both in the treatment area and in a control area...

INTRODUCTION: Cutaneous sclerosis can lead to important mobility impairment. Ultraviolet (UV) A1 phototherapy may improve skin sclerosis, although most of the studies have been with Caucasian patients. MATERIAL AND METHODS: A 44-year-old patient, Fitzpatrick skin type VI, was being followed up with the diagnosis of diffuse cutaneous systemic sclerosis. He had significant mobility impairment, especially of the right hand and arm. In 2015 he started UVA1 phototherapy daily, Monday until Friday (Waldmann® 7001 UVA cabin equipped with 40 Philips TL/10R lamps - spectral irradiation between 340 and 400 nm)...

HIV significantly affects the immunological environment during tuberculosis coinfection, and therefore may influence the selective landscape upon which M. tuberculosis evolves. To test this hypothesis whole genome sequences were determined for 169 South African M. tuberculosis strains from HIV-1 coinfected and uninfected individuals and analyzed using two Bayesian codon-model based selection analysis approaches: FUBAR which was used to detect persistent positive and negative selection (selection respectively favoring and disfavoring nonsynonymous substitutions); and MEDS which was used to detect episodic directional selection specifically favoring nonsynonymous substitutions within HIV-1 infected individuals...
