Lawsonia intracellularis is a gram-negative obligate intracellular bacterium causing Proliferative Enteropathy in pigs, leading to significant economic losses in the swine industry. Vaccination offers an alternative to antibiotics for controlling this pathogen. This systematic review evaluates the efficacy of commercial and experimental vaccines against Lawsonia intracellularis in pigs, focusing on clinical outcomes and immuno...

Germplasm banks are important for preserving genetic diversity, yet the availability and long-term maintenance of macroalgal strains in germplasm banks is currently limited in European collections. To support future food security, restoration efforts, and biotechnological innovation, a strategy was recently developed for the long-term preservation of macroalgal genetic diversity. A foundational step in this effort is to assess...

Climate change has intensified negative impacts on biodiversity through changes in precipitation patterns and rising global average temperatures. Semi-arid regions, such as parts of Northeastern Brazil, are particularly susceptible to these changes, with projections indicating that they will become hotter and drier, reducing the climatic suitability of several plant species. In this context, endemic and restricted-range specie...

Climate change intensifies drought in several regions. Here, we assess how water availability and air humidity regulate photosynthesis in epiphytic cyanobacterial biofilms on Jacaranda mimosifolia . We combined field measurements with controlled laboratory experiments, exposing biofilms to hydration–dehydration cycles and assessing, by chlorophyll fluorescence: potential quantum yield (Fv/Fm), relative electron transport rate...

This study evaluated the effects of increasing inclusion levels of biological silage produced from tambaqui ( Colossoma macropomum ) by-products (BST) in diets of commercial hens at different ages. A completely randomized design in a 2 × 5 factorial arrangement was adopted, comprising two hen ages (23 and 83 weeks) and five BST inclusion levels (0, 1, 2, 3, and 4%), with four replicates of six birds per treatment. Moderate BST...

Scaling up wind and solar energy is essential for decarbonization, yet local contestation frequently delays projects, making social acceptance a critical enabling condition. This study examines the institutional drivers of acceptance by analyzing how trust, participation, transparency, and perceived impacts shape residents’ evaluations of renewable energy developments. It addresses four questions: how trust in key stakeholders...

Frontotemporal dementia (FTD) is a neurodegenerative disease characterized by significant clinical and genetic heterogeneity, with approximately 40% of cases linked to hereditary genetic mutations, including MAPT , GRN , and C9ORF72 . Recently, microRNAs (miRNAs) have emerged as key regulators of cellular processes related to neurodegeneration and as potential biomarkers for FTD. However, their relevance in presymptomatic stag...

Myeloperoxidase (MPO) has been associated with a broad range of chronic inflammatory diseases since activated MPO catalyzes the production of HOCl, triggering both oxidative stress and inflammation. Since benzohydrazides are known as MPO inhibitors, a series of six N '-phenylbenzohydrazides and one quinazolin-4(3 H )-one analogue was evaluated through in vitro assays to measure inhibition of MPO, superoxide dismutase (SOD), an...

Background/Objective Although different neuromuscular strength (NS) cutoff points have been proposed to identify low walking speed (WS) in older adults, the extent to which NS changes predict long-term WS decline remains unclear. This study aimed to determine the percentage of NS change associated with WS decline in older adults. Methods A longitudinal analysis was conducted using data from 4,541 participants aged ≥ 60 years i...

Black root rot, caused by two Berkeleyomyces species ( B. basicola and B. rouxiae ), is a major disease of lettuce ( Lactuca sativa L.) in tropical areas. Nationwide surveys in Brazil indicated similar levels of incidence as well as an overlapping geographical distribution of B. basicola and B. rouxiae across major lettuce-producing areas. The most promising strategy for managing these polyphagous and aggressive pathogens is t...
