AI Article Synopsis
- A study conducted in 1983 and 1984 examined nematode populations in root and soil samples from potato fields in Suffolk County, New York, showing that higher populations of Pratylenchus spp. were observed in fields previously planted with rye or wheat compared to potatoes.
- Population densities varied significantly between the two areas of Suffolk County, with the south fork showing 1.9-5.5 times higher counts than the north fork, regardless of the prior crop planted.
- Different species of Pratylenchus, specifically P. penetrans and P. crenatus, were found predominately in the north and south forks respectively, with their distribution linked to soil types: P. cren
Article Abstract
Root and soil samples from commercial potato fields were assayed for nematodes in 1983 and 1984. Pratylenchus spp. population densities in Suffolk County, New York, were consistently, though not always statistically, higher in potato fields that had been planted to rye or wheat rather than potatoes during the previous growing season. Regardless of the previous crop, population densities in the two potato production areas in Suffolk County differed significantly: population densities on the south fork were 1.9-5.5 times higher than those on the north fork. Species prevalence differed significantly on the two forks but was not related to the previous year's crop. P. penetrans and P. crenatus were found primarily on the north and south forks, respectively. Differences in species distribution were associated with differences in soil types. P. crenatus was usually found on loams and silt loams, but P. penetrans was found more frequently on sandy soils.

Psoas muscle gauge and adverse clinical outcomes in patients on hemodialysis.
J Nephrol
January 2025
Department of Nephrology, Matsunami General Hospital, Gifu, Japan.
Background: The relationship between the psoas muscle gauge (PMG), a combined sarcopenia indicator obtained from psoas muscle index (PMI) and psoas muscle density (PMD), and adverse clinical outcomes in patients on hemodialysis remains unclear. We examined whether psoas muscle gauge could predict all-cause mortality and new cardiovascular events more accurately than psoas muscle index in these patients.
Methods: We retrospectively included 217 hemodialysis patients who underwent abdominal computed tomography.
Association Between Plasmodium Infection and Blood Count Values: Implications for Malaria Diagnosis in Resource-Limited Settings.
Acta Parasitol

Department of Biomedicine and Biotechnology, Faculty of Medicine, University of Alcala, Alcala de Henares, Spain.
Purpose: Malaria remains a major global health challenge, particularly in sub-Saharan Africa and low- and middle-income countries (LMICs), contributing substantially to mortality and morbidity rates. In resource-limited settings, access to specialized diagnostic tests is often restricted, making basic blood analysis a valuable diagnostic tool. This study investigated the correlation between malaria infection and full blood count values in a rural region of Ghana during the 2022 rainy season, aiming to highlight diagnostic insights available from routine blood analyses.

Context: Previous studies have explored the relationship between vitamin D and lipid profile in individuals with obesity or overweight women, but the results have been inconsistent.
Objective: This meta-analysis and systematic review of randomized controlled trials (RCTs) was conducted to assess the effect of vitamin D on lipid profile in women who are overweight or obese.
Data Sources: A meticulous search strategy was used across the Scopus, PubMed/Medline, Web of Science, and Embase databases up to June 2024.
Infrared Ion Spectroscopy of Gaseous [Cu(2,2'-Bipyridine)]: Investigation of Jahn-Teller Elongation Versus Compression.
J Phys Chem A

Institute for Molecules and Materials, FELIX Laboratory, Radboud University, Toernooiveld 7, 6525 ED Nijmegen, The Netherlands.
Symmetry breaking is ubiquitous in chemical transformations and affects various physicochemical properties of materials and molecules; Jahn-Teller (JT) distortion of hexa-coordinated transition-metal-ligand complexes falls within this paradigm. An uneven occupancy of degenerate 3d-orbitals forces the complex to adopt an axially elongated or compressed geometry, lowering the symmetry of the system and lifting the degeneracy. Coordination complexes of Cu are known to exhibit axial elongation, while compression is far less common, although this may be due to the lack of rigorous experimental verification.

Occurrence of microplastics in the environment is well studied, but our knowledge of their distribution in specific locations, such as the sandboxes, which are integral parts of popular playgrounds for children, is limited. Pioneering research on the factors affecting the microplastic pollution of sandboxes in urban residential areas was conducted within three estates in Kielce, Poland. Sand samples (Σ27) were collected from nine sandboxes and examined for the presence of microplastics, using a simple quality control methodology proposed by the authors.
