Uncovering a novel mechanism: Butyrate induces estrogen receptor alpha activation independent of estrogen stimulation in MCF-7 breast cancer cells.

Butyrate is a promising candidate for an antitumoral drug, as it promotes cancer cell apoptosis and reduces hormone receptor activity, while promoting differentiation and proliferation in normal cells. However, the effects of low-dose butyrate on breast cancer cell cultures are unclear. We explored the impact of sub-therapeutic doses of butyrate on estrogen receptor alpha (ERα) transcriptional activity in MCF-7 cells, using RT-qPCR, Western blot, wound-healing assays, and chromatin immunoprecipitation.

Antioxidant and Antibacterial Activity of Mexican Oregano Essential Oil, Extracted from Plants Occurring Naturally in Semiarid Areas and Cultivated in the Field and Greenhouse in Northern Mexico.

In recent years, the determination of the antioxidant and antibacterial activity of essential oils in wild plants, such as Mexican oregano ( Kunth), has become increasingly important. The objective was to compare the antioxidant and antibacterial activity of Mexican oregano essential oil obtained from plants occurring naturally in semiarid areas (Wild1 and Wild2), and those cultivated in the field (CField) and greenhouse (CGreenhouse) in northern Mexico. The Mexican oregano essential oil extraction was performed using the hydrodistillation method, the antioxidant activity was determined using the ABTS method, and the antibacterial activity was assessed through bioassays under the microwell method at nine different concentrations.

Relationship Between Weight and Severity of Fibromyalgia.

Unlabelled: Fibromyalgia is a chronic pain syndrome with diffuse pain, muscle weakness, and other symptoms. A relationship between the severity of symptoms and obesity has been observed.

Objective: To determine the relationship between weight and the severity of fibromyalgia.

Arsenic: A Perspective on Its Effect on Pioglitazone Bioavailability.

Unlabelled: Arsenic (As) is a common contaminant in drinking water in northeastern Mexico, which reduces the expression of cytochrome P450 (CYP 450). This enzyme group metabolizes numerous drugs, such as oral antidiabetic drugs such as pioglitazone (61% CYP 3A4, 49% CYP 2C8). When CYP 450's function is inadequate, it has decreased therapeutic activity in type 2 diabetes mellitus (T2DM).

The Triglycerides and Glucose Index Is Associated with Mild Cognitive Impairment in Older Adults.

Background: It has been reported that insulin resistance is related to cognitive decline. The triglycerides and glucose (TyG) index, is a reliable and inexpensive surrogate test for detecting insulin resistance.

Aims: The goal of this study was to evaluate the association between the TyG index and the mild cognitive impairment (MCI) in older adults.

α-syn and SNP rs356219 as a potential biomarker in blood for Parkinson's disease in Mexican Mestizos.

Clinical criteria diagnose Parkinson's disease (PD), therefore, it is crucial to find biological elements that could support diagnosis or even act as prognostic tools of PD. The SNCA gene codifies a protein called α - synuclein; several studies associate genetic and biochemical factors of SNCA with PD, including transcript and plasmatic protein levels, however, contradictory evidence indicates inconclusive results. We aim to compare SNCA mRNA expression, plasmatic α-syn protein and rs356219 SNP between PD cases and a control group, and to identify a potential biomarker in Mexican mestizos', focusing on these three components determined in blood.

[Pioglitazone hydrochloride a instrumental analytical perspective by Raman spectroscopy and HPLC].

Introduction: The thiazolidinediones (pioglitazone) increases the action of insulin and produces the glycemic control in the patients with type 2 diabetes mellitus. Also, the pharmacological effect may be affected by the purity and pioglitazone plasma concentration. Therefore, the instrumental techniques offer a tool for characterization, identification and/or quantification of the pioglitazone; Raman spectroscopy offers several advantages due to its easy application methodology and structural analysis and the HPLC technique is the gold standard vs.

C allele of the rs2209972 single nucleotide polymorphism of the insulin degrading enzyme gene and Alzheimer's disease in type 2 diabetes, a case control study.

Background And Objective: In the last few decades we have witnessed an interesting transformation of the population pyramids throughout the world. As the population's life expectancy increases, there are more chronic diseases such as diabetes mellitus and dementias, and both of them have shown an association.

General Objetive: To determine the association between Alzheimer's disease in diabetic patients and the insulin degrading enzyme in outpatients of a second level Hospital in Monterrey, Mexico.

Association between polymorphism c.1-765G>C of the COX2 gene and cognitive impairment in individuals 65 years or more with diabetes from a Geriatric Service in Monterrey, Mexico.

Background And Objective: Cognitive impairment and dementia are common geriatric syndromes in diabetic patients. Inflammation plays a crucial role in the pathophysiology of Alzheimer's disease and cognitive impairment. Cyclooxygenases (COX) 1 and 2 participate in inflammation.
