[Association between food behavior and hypercholesterolemia-LDL in university students].

Introduction: Hypercholesterolemia-LDL (H-LDL) is associated with increased risk of cardiovascular disease. The association between H-LDL and feeding has focused on nutritional aspects. The study of the association between eating behavior (EB) and H-LDL in university students, could provide nutritional elements for correction and/or prevention in this population.

Expression of WNT genes in cervical cancer-derived cells: Implication of WNT7A in cell proliferation and migration.

According to the multifactorial model of cervical cancer (CC) causation, it is now recognized that other modifications, in addition to Human papillomavirus (HPV) infection, are necessary for the development of this neoplasia. Among these, it has been proposed that a dysregulation of the WNT pathway might favor malignant progression of HPV-immortalized keratinocytes. The aim of this study was to identify components of the WNT pathway differentially expressed in CC vs.

Expression of autocrine prolactin and the short isoform of prolactin receptor are associated with inflammatory response and apoptosis in monocytes stimulated with Mycobacterium bovis proteins.

Increased levels of prolactin (PRL) have recently been associated with carcinogenesis and the exacerbation of autoimmune diseases, and might be involved in the progression of tuberculosis (TB). To investigate the relationship between PRL and prolactin receptor (PRLr) expression with inflammatory response and apoptosis in monocytes, we used THP-1 cells stimulated with antigens of the Mycobacterium bovis AN5 strain culture filtrate protein (CFP-M. bovis).

Beneficial effects of quercetin on oxidative stress in liver and kidney induced by titanium dioxide (TiO2) nanoparticles in rats.

TiO2 nanoparticles used as vectors for the delivery of drugs have shown greater effectiveness. However, TiO2 nanoparticles can cause oxidative stress in liver and kidney, so we analyzed if a previous or simultaneous quercetin treatment could counteract this in rats. Five groups of male Wistar rats (200-250 g) were included: (1) healthy controls, (2) TiO2 group, (3) quercetin group, (4) preventive group: quercetin for 5 days prior to exposure of TiO2, and (5) therapeutic group: TiO2 (5 mg/kg, i.

Expression of transcription factor grainyhead-like 2 is diminished in cervical cancer.

The transcription factor grainyhead-like 2 (GRHL2) is evolutionarily conserved in many different species, and is involved in morphogenesis, epithelial differentiation, and the control of the epithelial-mesenchymal transition. It has also recently been implicated in carcinogenesis, but its role in this remains controversial. Expression of GRHL2 has not previously been reported in cervical cancer, so the present study aimed to characterize GRHL2 expression in cervical cancer-derived cell lines (CCCLs) and cervical tissues with different grades of lesions.

[Temporal lobe epilepsy and active neurocysticercosis: two representative case reports].

Introduction: There are limited evidences reported of temporal lobe epilepsy associated with active cysticercosis in cystic stage. The objective is to present the correlation between active cysticercosis in topographical zones associated with temporal lobe epilepsy, with neuropsychiatric manifestations and pattern of secondarily generalized partial seizures.

Case Reports: Two cases of adult patients with neuropsychiatric manifestations of one year evolution, refractory to antipsychotic drug treatment, and who subsequently appear late onset partial-secondarily generalized seizures.

Role of the blood-brain barrier in multiple sclerosis.

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system associated with demyelination and axonal loss eventually leading to neurodegeneration. MS exhibits many of the hallmarks of an inflammatory autoimmune disorder including breakdown of the blood-brain barrier (BBB). The BBB is a complex organization of cerebral endothelial cells, pericytes and their basal lamina, which are surrounded and supported by astrocytes and perivascular macrophages.

Cervical cancer cell supernatants induce a phenotypic switch from U937-derived macrophage-activated M1 state into M2-like suppressor phenotype with change in Toll-like receptor profile.

Unlabelled: Cervical cancer (CC) is the second most common cancer among women worldwide. Infection with human papillomavirus (HPV) is the main risk factor for developing CC. Macrophages are important immune effector cells; they can be differentiated into two phenotypes, identified as M1 (classically activated) and M2 (alternatively activated).

Increase of IFN-γ and TNF-α production in CD107a + NK-92 cells co-cultured with cervical cancer cell lines pre-treated with the HO-1 inhibitor.

Background: Natural killer (NK) cells eliminate virus-infected and tumor cells through the release of perforins and granzymes; they also produce Interferon gamma (IFN-γ) and Tumor necrosis factor alpha (TNF-α), which induce apoptosis in target cells. Many tumors express Heme oxygenase 1 (HO-1), and this expression has been associated with avoiding immunosuppression and apoptosis. In this work, HO-1+ Cervical cancer cell (CCC) lines were pre-treated with HO-1 inhibitor and we assessed whether this inhibition enhanced the sensitivity of CCC to NK cell activity.

Procollagen Type I and III Aminoterminal Propeptide Levels and Severity of Interstitial Lung Disease in Mexican Women With Progressive Systemic Sclerosis.

Background: Interstitial lung disease (ILD) is a frequent complication in progressive systemic sclerosis (SSc), being present in 25% to 90% of cases.

Objectives: To evaluate whether serum levels of procollagen typei and iii aminoterminal propeptide (PINP and PIIINP) correlate with severity and patterns of ILD in Mexican women with SSc.

Methods: Thirty three SSc patients were assessed for disease characteristics and anti-topoisomerase antibodies (topoi), and also underwent pulmonary function tests and high-resolution computed tomography (HRCT).

Modifications in lipid levels are independent of serum TNF-α in rheumatoid arthritis: results of an observational 24-week cohort study comparing patients receiving etanercept plus methotrexate or methotrexate as monotherapy.

Objective: To compare the modifications in lipids between patients with rheumatoid arthritis (RA) receiving etanercept plus methotrexate (ETA + MTX) versus methotrexate (MTX) and their relationship with serum levels of tumor necrosis factor-alpha (TNF-α).

Methods: In an observational cohort study, we compared changes in lipid levels in patients receiving ETA + MTX versus MTX in RA. These groups were assessed at baseline and at 4 and 24 weeks, measuring clinical outcomes, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, and TNF-α.

[Polymorphism g.37190613 G>A of the ELMO1 gene in the Mexican population: potential marker for clinical-surgical pathology].

Background: ELMO1 is a gene located at locus 7p14.2-14.1 that codifies a regulatory protein involved in fibrogenesis, cell migration, phagocytosis and apoptosis.

Comparison of two assays to determine anti-citrullinated peptide antibodies in rheumatoid arthritis in relation to other chronic inflammatory rheumatic diseases: assaying anti-modified citrullinated vimentin antibodies adds value to second-generation anti-citrullinated cyclic peptides testing.

Determination of anti-citrullinated peptide antibodies (ACPA) plays a relevant role in the diagnosis of rheumatoid arthritis (RA). To date, it is still unclear if the use of several tests for these autoantibodies in the same patient offers additional value as compared to performing only one test. Therefore, we evaluated the performance of using two assays for ACPA: second-generation anti-citrullinated cyclic peptides antibodies (anti-CCP2) and anti-mutated citrullinated vimentin (anti-MCV) antibodies for the diagnosis of RA.

Inhibitory mechanisms of two Uncaria tomentosa extracts affecting the Wnt-signaling pathway.

Uncaria tomentosa ("uña de gato"; "cat's claw"), a woody vine native to the Amazon rainforest, is commonly used in South American traditional medicine to treat a broad spectrum of diseases. Although recent studies have reported anti-inflammatory and anti-proliferative properties of different alkaloids extracted from this plant, the underlying molecular mechanisms of these effects have not been elucidated yet. Our study investigates the inhibitory mechanisms of Uncaria tomentosa extracts on the Wnt-signaling pathway, a central regulator of development and tissue homoeostasis.
