Despite legal safeguards, the Yanomami community faces challenges such as unauthorized incursions by gold miners, resulting in environmental degradation, particularly from mercury. This jeopardizes the health and food security of indigenous individuals, especially due to the consumption of contaminated fish. Ethnic and racial disparities persist in indigenous healthcare, marked by troubling health indicators such as malnutrition, anemia, and infectious diseases.

Endometriosis presents a pro-inflammatory microenvironment influenced by cytokines, such as interleukin (IL)-8, which expression may be influenced by genetic polymorphisms. Therefore, we aimed to investigate the role of interleukin (IL)-8 rs4073 polymorphism in endometriosis' development and its related symptoms. A case-control study was conducted with 207 women with endometriosis and 193 healthy controls.

Genetic polymorphisms in the matrix metalloproteinases () family genes may be associated with cadmium (Cd) levels and its adverse effects. This study investigated the impact of and polymorphisms on Cd levels in 238 residents of a condominium in Rio de Janeiro, Brazil, built over an industrial steel slag waste. Polymorphisms were genotyped using TaqMan validated assays, and the Cd levels were measured in blood (BCd) and urine (UCd) samples by atomic absorption spectrometry.

Article Synopsis
  • The study focused on patient care for COVID-19 in a Brazilian referral center, analyzing factors affecting mortality, length of stay, and diagnostic outcomes during May 2020 with a sample size of 1,100 patients.
  • 76% of patients tested positive for COVID-19, primarily through RT-qPCR, revealing a high prevalence of hypertension, diabetes, and obesity among individuals, especially those aged over 52.
  • Key findings indicated that age, pulmonary impairment, and hypertension significantly impacted patient mortality and hospitalization duration, emphasizing the importance of timely sample collection for accurate diagnosis.

Objective: Endometriosis has a complex and multifactorial pathology, and it is considered one of the main causes of infertility nowadays. The angiogenic process, which involves remodeling of extracellular matrix, is crucial for the development of this disease, mainly by the action of the matrix metalloproteinase 3 (MMP-3). It is known that genetic factors can influence endometriosis, thus; we investigated the role of polymorphism as a risk factor for the development of the disease and its symptoms.

Objective And Design: Among the options for treatment of diseases affecting the respiratory system, especially asthma, drug delivering systems for intranasal application represent an important therapeutic approach at the site of inflammation. The present study aimed to evaluate the therapeutic effect of biodegradable microparticles formed by poly lactic-co-glycolic acid (PLGA) containing encapsulated pomegranate extract on a murine model of asthma.

Material: The extract was acquired from the leaves of P.

The immunomodulatory and anti-inflammatory activities of green propolis extracts from Apis mellifera were investigated using acute and chronic inflammation models. Swiss mice were anesthetized and a cotton pellet granuloma was implanted in subcutaneous tissue. Then the mice were divided into six groups and received apyrogenic water or different propolis extracts by oral route (5 mg/kg).
