Survey of infectious diseases in Penaeus vannamei (Boone) from Costa Rica shrimp farms during 2017 and 2018
Introduction: Costa Rica has suitable environmental features to produce farmed shrimp, but infectious diseases are a major hurdle. Scarce information exists on the presence of viruses or bacterial pathogens in farmed shrimp in Costa Rica.Materials and methods: This study surveyed three pathogens of…

Antidiabetic and antioxidant potentials of selected traditional Palestinian medicinal plants
Introduction: Diabetes mellitus is a major and increasing public health burden in Palestine. Medicinal plants are widely employed in traditional practice, yet their antidiabetic efficacy and mechanisms remain insufficiently validated. This study aimed to evaluate the antidiabetic and antioxidant…

A brief critique of excitotoxicity in amyotrophic lateral sclerosis
The excitotoxicity hypothesis has been significantly influential in amyotrophic lateral sclerosis (ALS) research for over thirty years but has seen limited clinical success. Here, the evidence supporting excitotoxicity in ALS is re-examined from first principles, motivated by a critical question…

Phantom refugia for fruit-eating migratory fishes in dammed Neotropical rivers
Introduction: Climate change, river impoundment, and riparian degradation act synergistically to threaten Neotropical freshwater biodiversity, yet conservation approaches rarely integrate these stressors simultaneously. We developed a triple mismatch framework combining species distribution models…

Laboratory serial passage of Yersinia ruckeri: phenotypic and genomic virulence dynamics
Introduction: The routine serial passage of bacterial pathogens on artificial media is common in diagnostic and research laboratories, but such “laboratory domestication” may alter virulence traits and decouple reference strains from the field populations they are meant to represent.Materials and…

Journal Article
A hypothesis of ape and human evolution based on comparative biology and plate tectonics
There is broad consensus among paleoanthropologists that extant African hominids (Pan and Gorilla) as well as hominins (our direct ancestors following the split from Pan, i.e., chimpanzee and bonobo) originated in Africa. The prevailing view, that hominins became upright bipeds after moving from…

Behavioral and life history responses of an endangered sea lion (Otariidae) following a severe marine heatwave
Introduction: The northeast Pacific marine heatwave (PMH) of 2014–2016 had strong impacts on many species across a vast region. Impacts on upper trophic species, such as reduced survival and reproduction, were a clear consequence of reduced food availability.Materials and methods: We conducted a…

Journal Article
Can agriculturally damaging nematodes be controlled by use of green energy from onion crop residues and solar heating?
Introduction: Soil solarization (Sol) and biosolarization (BioS) are hydrothermal, organically acceptable alternatives to agricultural soil fumigation with synthetic chemical toxicants. Returning on- or off-site crop residues to decompose in soil as amendments in BioS can aid in promoting a…

Journal Article
Learning dynamics vs. aggregate metrics: clinical applicability of machine learning survival prediction in eye cancer
Introduction: The application of machine learning in healthcare requires models that demonstrate not only acceptable classification performance but also trustworthy learning behavior suitable for clinical deployment. Class imbalance represents a pervasive challenge in medical datasets, where…

Electrochemical DNA biosensor for rapid detection of Listeria monocytogenes in meat samples
Introduction: Listeriosis, a zoonosis caused by the consumption of food contaminated with L. monocytogenes, shows the highest fatality rate in Europe. Official methods are laborious and time-consuming; moreover, an underestimation of the microorganism number is possible due to a viable but…

Journal Article
Antibacterial activity of Ayapana triplinervis against multidrug-resistant Aeromonas in aquaculture
Introduction: Motile Aeromonas septicaemia (MAS), caused by multidrug-resistant (MDR) Aeromonas hydrophila and A. veronii, poses a significant threat to global aquaculture, necessitating sustainable alternatives to antibiotics.Materials and methods: This study characterized MDR Aeromonas isolates…

Journal Article
Penguin guano shapes Antarctic environmental microbiomes: insights from DNA metabarcoding
Introduction: Antarctic soils are characterized by extreme environmental conditions, including low temperatures, limited liquid water, and a scarcity of organic nutrients, fostering unique bacterial communities vital for biogeochemical cycling and ecosystem functioning. This study investigates the…

Journal Article
Rapid prediction of SARS-CoV-2 variant fitness using early frequency data
Introduction: The emergence of SARS-CoV-2 Variants of Concern (VOCs) has provided a powerful empirical demonstration of the importance of a phenotypic perspective in evolutionary dynamics.Materials and methods: This study utilizes high-resolution genomic surveillance data from the USA, UK, Germany…

Urine transcriptomic biomarkers for prostate cancer detection and risk stratification
Early and accurate diagnosis of prostate cancer remains challenging due to its biological heterogeneity and the limitations of current clinical tools. Widely used diagnostic approaches, including serum prostate-specific antigen (PSA) testing and biopsy, are associated with low specificity…

Journal Article
Genetic identity of three species of beaked whale (family Ziphiidae) off the Brazilian coast
Introduction: Studies on beaked whales in the South Atlantic are scarce, and there are still significant gaps in knowledge about these species in this region. In Brazil, ten species have been reported over the years. Most of these records, however, are limited to isolated stranding reports, and…

Journal Article
Y-STR haplotype diversity in Eritrean and Sudanese populations
Introduction: East Africa has been in the spotlight of paleoanthropological investigations for its role as a potential cradle of humanity and as a gateway out of Africa. Y chromosome single nucleotide polymorphisms (SNPs) and mitochondrial DNA genotyping of East African populations complement this…

Journal Article
Non-oral tissue regeneration, angiogenesis, and healing with enamel matrix derivative
Introduction: Enamel matrix derivative (EMD) is a biomaterial derived from developing porcine tooth structures, primarily composed of amelogenins, which have been shown to regulate fibroblast and osteoblast activity. While EMD is well-established in periodontal regeneration, its potential in…

Ecotoxicity of plastic nanoparticles in quagga mussels, Dreissena bugensis
Small plastic polymers have the potential to bioaccumulate in tissues and initiate toxicity, raising concerns about the long-term impacts on filter feeders such as freshwater mussels. The purpose of this study was to examine the toxicity of two common plastic polymers (polyvinyl chloride—PVC…

Journal Article
From traits to trajectories: development, agency and a phenotypic gap in demography
Demography links ecology and evolution by connecting population dynamics with variation in fitness and selection. Yet, most demographic models represent phenotypes as fixed traits and environments as static backdrops, overlooking the developmental processes through which phenotypes are constructed…

Ecological niche modeling of Aedes aegypti under climate change in Benin
Our study contributed to the protection of the health of the Beninese population against the vector-borne infectious disease dengue fever. Mosquito occurrence data were collected in the municipalities of Natitingou, Parakou, Abomey Calavi, and Cotonou, supplemented by data downloaded from the…
