Photogrammetric determination of movement speed of invasive Indo-Pacific lionfish in the Florida Keys.

As a key determinant of how efficiently lionfish ( sp.) locate and capture prey, swimming speed plays a crucial role in shaping the predator-prey interactions and broader ecological dynamics within the invaded ecosystems. Swimming speed on a small temporal and spatial scale is difficult to measure because of the need for precise measurements of both distance and duration of the behavior.

Crosstalk between Gut Microbiota and Cancer Immunotherapy: Present Investigations and Future Perspective.

Gut microbiota is crucial for protecting the homeostasis of immune locally and systemically, and its dysbiosis is essentially correlated to tumorigenesis, cancer progression, and refractoriness to cancer treatments, including the novel immunotherapy. Increasing evidence unravel the intricate role of gut microbiota in reshaping tumor microenvironment and affecting the efficacy and toxicities of immunotherapy, which shed more light on the future applications of gut microbiota in efficacious biomarker and combination treatment of immunotherapy. To better grasp the underlying crosstalk between gut microbiota and immunotherapy, more experimental and clinical trials are indispensable for the customized gut microbiota-based treatments in cancer patients undergoing immunotherapy.

Mechanically Triggered Protein Desulfurization.

The technology of native chemical ligation and postligation desulfurization has greatly expanded the scope of modern chemical protein synthesis. Here, we report that ultrasonic energy can trigger robust and clean protein desulfurization, and we developed an ultrasound-induced desulfurization (USID) strategy that is simple to use and generally applicable to peptides and proteins. The USID strategy involves a simple ultrasonic cleaning bath and an easy-to-use and easy-to-remove sonosensitizer, titanium dioxide.

Plantar sensation associates with gait instability in older adults.

Background: Advanced age brings a loss of plantar sensation, represented, for example, as higher sensation thresholds in standardized testing. This is thought to contribute to an increased risk of falls among older adults - an intuitive premise that has yet to be fully investigated, especially in the context of walking balance. The purpose of this study was to quantify the association between plantar sensation and the instability elicited by a suite of walking balance perturbations that differ in direction and context in a cohort of n = 28 older adults (73.

Survival Among Patients Treated with Total Mesorectal Excision or Selective Watch-and-Wait After Total Neoadjuvant Therapy: A Pooled Analysis of the CAO/ARO/AIO-12 and OPRA Randomized Phase II Trials.

Background: Prospective data comparing watch-and-wait (WW) to mandatory total mesorectal excision (TME) in patients with locally advanced rectal cancer (LARC) remains limited, as randomized control trials assessing these two treatment approaches are considered impractical. This pooled analysis of the CAO/ARO/AIO-12 and OPRA trials analyzes survival outcomes among LARC patients managed with either a selective WW or mandatory TME strategy following total neoadjuvant therapy (TNT).

Patients And Methods: The CAO/ARO/AIO-12 and OPRA trials were multicenter, phase II trials that randomized patients with stage II/III rectal cancer to receive either induction or consolidation chemotherapy as part of TNT.

Risk of carcinomas among children and adolescents with birth defects.

Background: Birth defects are associated with childhood cancer, but little is known regarding pediatric carcinomas, a group of especially rare tumors.

Methods: We used Cox proportional hazards regression to estimate the hazard ratio (HR) and 95 % confidence interval (CI) for any carcinoma, as well as thyroid, hepatocellular, and renal carcinoma specifically, up to 18 years of age among children with major, non-syndromic anomalies or chromosomal/genetic syndromes, relative to unaffected children.

Results: Our registry-linkage study included nine states and 21,933,476 children between 1990 and 2018: 641,827 with non-syndromic anomalies, and 49,619 with syndromes.

Online analysis of Amazon's soils through reflectance spectroscopy and cloud computing can support policies and the sustainable development.

Analyzing soil in large and remote areas such as the Amazon River Basin (ARB) is unviable when it is entirely performed by wet labs using traditional methods due to the scarcity of labs and the significant workforce requirements, increasing costs, time, and waste. Remote sensing, combined with cloud computing, enhances soil analysis by modeling soil from spectral data and overcoming the limitations of traditional methods. We verified the potential of soil spectroscopy in conjunction with cloud-based computing to predict soil organic carbon (SOC) and particle size (sand, silt, and clay) content from the Amazon region.

Plant nutrient concentrations inform white-tailed deer diet limitations.

Management of large herbivores often involves increasing availability of forages sufficient in nutrient density to allow animals to meet dietary demands. Nutritional carrying capacity (NCC) models commonly are used to compare plant communities and management strategies, but failure to use the most limiting nutrient could result in overestimating NCC. Moreover, the relationship between limiting nutrients often is not considered, which may influence the utility of NCC models based on a single nutrient, especially when herbivores must simultaneously meet multiple constraints.

Does exercise demonstrate a dose-dependent benefit with cognition in Parkinson's disease?

Background: Exercise confers motor benefits in Parkinson's disease (PD) and may even have disease modifying effects. While the impact of exercise on motor symptoms and quality of life is well-studied in PD, its relationship with cognitive performance warrants further attention.

Methods: In people with PD, self-reported exercise information was quantified using the Rapid Assessment of Physical Activity (RAPA).

This study aimed to explore the linkages between natural and structural disasters, mental health, and energy independence in Puerto Rico.

Early insights of dengue virus serotype 3 (DENV-3) re-emergence in São Paulo, Brazil.

Background: In dengue hyperendemic regions, the evolution of the virus is marked by frequent virus introduction/reintroduction and clade replacement events, occasionally linked to an epidemic outbreak. From 2023 onwards, an increase in the detection of DENV-3 cases has been reported in different regions of Brazil. Thus, molecular and genomic surveillance of circulating DENV strains is crucial for public health preparedness and response efforts for the disease.

Cranial variation across spiny pocket mice (Heteromys, Liomys) in new phylogenetic and taxonomic perspectives.

Spiny pocket mice are usually divided into two genera, Heteromys and Liomys, and more recently the latter have been subsumed into the former, leaving subfamily Heteromyinae with one genus. However, this arrangement conveys false equivalency among heteromyines, and does not represent the great morphological, molecular, and ecological diversity in this subfamily. To address this, geometric morphometric methods were used to explore interspecific cranial variation in this subfamily, which were then evaluated in the context of recent phylogenetic and taxonomic findings.
