Non Alcoholic Fatty Liver Disease (NAFDL) is a condition in which an individual suffers from an accumulation of fat in the liver. This is a disease condition with a multifactorial etiology. Some potent causes of such conditions are altered thyroid condition, abnormal metabolism in the body due to aging or menopause, or any other hormonal imbalance. Most of these causes are regulated by genetics, lifestyle, and environmental factors. Menopause comes with tremendous hormonal turmoil in the human body and brings vario [...]

(1) Background: Platelet function is commonly altered in liver cirrhosis. In experimenta models of liver cirrhosis we have analyzed the mechanisms of this defective function. (2) Methods: Experiments were performed in a model of liver cirrhosis by bile duct-ligation in washed platelets by means of fluorescence spectroscopy with fura-2. (3) Results: We have found several alterations compatible with the existence of a hyperaggregatory state. These alterations are related to a defective platelet calcium handling, spec [...]

The present research was part of a cross-sectional project involving children aged 8 to 10 years in Porto, Portugal. The project involved a first research part at primary schools where the health tests and a questionnaire were performed and a second research part concerning environmental conditions. Two groups emerged from the health questionnaire answers: one group that reported “asthma diagnosed by a doctor” and/or “wheezing or whistling in the chest during last 12 months” and another that answered negatively to [...]

In conventional wireline and LWD/MWD formation testing, downhole predictions for rock and fluid properties are based on simplified Darcy flow models, but only for mathematical expediency. These require initially constant pressures that are uniform throughout the reservoir. This limitation precludes common applications in overbalanced drilling, so that supercharge or near-well invasion effects - associated with rapidly decreasing pressures at the sandface where pressures are measured - are completely ignored. Such 1 [...]

This paper studies and characterizes a solar collector with spherical geometry to produce hot water for sanitary and domestic applications and other facilities. The new geometry enlarges the solar collector surface and allows full sun tracking during the day without needing a solar tracking system. Although this geometry has been in use for some time, its market penetration is low due to the lack of perfect knowledge of solar collector behavior and the benefits compared with conventional solar collectors. The studi [...]

According to 2019 WHO data, neurological conditions contribute to 1503.39 disability-adjusted life years (DALYs) per 100,000 population. Approximately 57% of office-based physicians use EHR systems and the natural place to incorporate standardized ePRO is into EHR. However, implementing patient-reported outcomes (PROs) for neurological conditions is challenging because many patients are elderly, have comorbidities, and experience cognitive impairment. As healthcare digitization increases, we propose a framework for [...]

Race, while a social construct, has a strong effect on a person’s health. There is limited data on racial disparities within lung transplantation (LTx), especially for Hispanic recipients. Therefore, the aim of this study was to identify inequalities that may involve this population. We analyzed historical data from the Organ Procurement and Transplantation Network (OPTN) and performed a retrospective review of Hispanic and Caucasian patients who underwent lung transplantation in the United States between May [...]

Acne is a chronic inflammatory condition affecting the pilosebaceous units of the skin, characterized by the formation of papules, cysts, comedones, pustules, nodules, and scars. These lesions are typically located on the face and shoulders, although they can extend to the trunk, arms, and legs. In regenerative medicine, biomolecules are fundamental to tissue regeneration. The use of growth factors from autologous platelet-rich plasma emerges as a promising alternative in the treatment of acne and scars. This study [...]

The urgency to manage global methane emissions has been acknowledged with international pledges to reduce 2020 levels by 30% by 2030. Carbon management requires effective tools to monitor changes, including those from significant sources including waste disposed on land. The first order degradation model used to determine landfill methane emissions, has been described by researchers as highly variable, insensitive and inadequate, despite recent attempts to explain microclimate impacts on methane oxidation. The deve [...]
