Mitochondrial dysfunction plays a critical role in the development of metabolic dysfunction-associated steatotic liver disease (MASLD). It has been proposed that mitochondrial unfolded-protein response (UPR mt ) activation improves mitochondrial function in the liver. Growing evidence demonstrates that physical exercise effectively prevents and treats MASLD. However, the effects of exercise on UPR mt activation in the liver ar...

This study evaluated the effects of providing 3–15 kg of a soluble and biodegradable biopolymer-based enrichment material (blend of biodegradable polymers and natural fibers) to prepartum sows housed in farrowing crates. Fifteen sows were blocked by body weight and backfat thickness and assigned to three treatments: no enrichment material (CONT), 3 kg of enrichment material (BN3), or 15 kg of enrichment material with added nut...

Pathogenic fungi that cause rust adversely affect plants, including crops, affecting them differentially depending on the cultivar. This is the case of blackberry ( Rubus spp.), a member of Rosaceae, introduced in Brazil by Embrapa during the 1980s and 1990s. Given the advantageous nutritional properties of its fruits and the relatively low management costs associated with its cultivation, blackberry production has emerged as...

In this work, the environmental occurrence ranges of different European cephalopod species are described for the whole NE Atlantic shelf including the greater North Sea and Baltic Sea. This is done based on the environmental parameters collected in-situ during surveys that caught commercially important cephalopod species (1990–2022). Results are supplemented and compared with information available in the published literature a...

Background and Aims For Azospirillum to promote plant growth, successful colonization of the associated plant is required. However, the factors governing the interaction between Azospirillum and plants remain unknown. Methods To examine these associations, a deletion mutant strain of Azospirillum brasilense FP2 was constructed by targeting the narL-like gene, which is highly expressed in bacteria colonizing wheat roots. We the...

The Southwestern Atlantic Ocean (SWAO) is an important feeding and developmental area for loggerhead turtle ( Caretta caretta ). However, long-term patterns of resource use across life stages and sexes remain poorly understood for the species in this region. Here, we used stable isotope analysis (SIA) of sequential layers of carapace scutes to investigate resource use of loggerhead turtles in the SWAO across life stages and se...

The common bottlenose dolphin ( Tursiops truncatus ) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings ( n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis ( n = 43 from 1997 to 2019) along the Portuguese mainland coast. Strandings were more frequent in the...

This study identified four hidden rainfall states in Northeast Brazil (NEB) during the austral autumn (March–May) from 1981 to 2015 using a Hidden Markov Model (HMM). Two states correspond to widespread dry (State 1) and wet (State 2) conditions, both exhibiting strong daily persistence and associations with large‐scale atmospheric features, including the Intertropical Convergence Zone (ITCZ), the South American Monsoon System...

Marine primary production, converting approximately 50 Gt of inorganic carbon into organic carbon per year, is an important component of the global carbon cycle, and a major determinant of past, present and future climate. Large-scale, long-term estimates of marine primary production rely primarily on two types of models: satellite-based models that make extensive use of remote-sensing data, and ecosystem models providing nume...

Aluminum (Al) toxicity is the main factor limiting agricultural production in acidic soils around the world. In this scenario, melatonin (MET) has emerged as a promising approach to alleviate Al toxicity. Thus, we investigated morphophysiological responses of Pfaffia glomerata (Spreng.) Pedersen, a medicinal plant, to Al toxicity and MET application. Plants were grown in vitro for 40 days in MS medium (control) supplemented wi...
