To expand the single-dose duration over which noninvasive clinical and preclinical cancer imaging can be conducted with high sensitivity,and well-defined spatial and temporal resolutions,a facile strategy to prepare ultrasmall nanoparticulate X-ray contrast media(nano-XRCM)as dual-modality imaging agents for positron emission tomography(PET)and computed tomography(CT)has been *** from controlled copolymerization of triiodobenzoyl ethyl acrylate and oligo(ethylene oxide)acrylate monomers,the amphiphilic statistical iodocopolymers(ICPs)could directly dissolve in water to afford thermodynamically stable solutions with high aqueous iodine concentrations(>140 mg iodine/mL water)and comparable viscosities to conventional small molecule *** formation of ultrasmall iodinated nanoparticles with hydrodynamic diameters of ca.10 nm in water was confirmed by dynamic and static light scattering *** a breast cancer mouse model,in vivo biodistribution studies revealed that the64Cu-chelator-functionalized iodinated nano-XRCM exhibited extended blood residency and higher tumor accumulation compared to typical small molecule imaging ***/CT imaging of tumor over 3 days showed good correlation between PET and CT signals,while CT imaging allowed continuous observation of tumor retention even after 10 days post-injection,enabling longitudinal monitoring of tumor retention for imaging or potentially therapeutic effect after a single administration of nano-XRCM.

Loneliness is classically defined as a result of perceiving a discrepancy between the desired quantity and quality of one's social life and actual social relationships(Perlman and Peplau,1984).Lifespan research has indicated older adults are among the highest risk for experiencing loneliness because their social network size decreases more frequently than that of younger adults.

Glyphosate Exposure Associated with Human Neurodegenerative Disorders: A Scoping Review

引用

Journal of Behavioral and Brain Science 2024年第7期14卷 187-209页

作者： hannah Hutchins David M. Compton Kris Dougherty Behavioral Neuroscience Program Palm Beach Atlantic University West Palm Beach Florida USA Department of Biology Palm Beach Atlantic University West Palm Beach Florida USA

Chemically engineered agricultural products such as pesticides, insecticides, and herbicides, although used considerably for both industrialized and personal agricultural use, have recently been associated with a number of serious human health disorders. This rapid literature review aims to accumulate and analyze research from the last ten years, focusing specifically on the effects of exposure to glyphosate-based herbicide products such as Roundup as associated with the formation of various neurological disorders. Specifically, this review focuses on laboratory research using animal models or human cell cultures as well as human population-based epidemiological studies. It associates exposure to glyphosate or glyphosate-based products with the formation or exacerbation of neurological disorders such as Parkinson’s disease, Alzheimer’s disease, seizures, and autism spectrum disorder. In addition, it examines the correlation between the gut-brain axis, exposure to glyphosate, and neurodegeneration.

作者： Mathias Reichert Ame Strauß Joost Wilhelm Voß Hans Christoph von Knobloch hannah Maria Neuenhofer Annemarie Uhlig Lutz Trojan Mirjam Naomi Mohr Department of Urology University Medical CenterGoettingenGermany Department of Pediatrics University HospitalBonnGermany

Purpose:The aim of the study was to examine the influence of the surgical approach for robot-assisted laparoscopic prostatectomy(RALP)on long-term urinary continence status in the era of self-reported functional status measures using the Expanded Prostate Can-cer Index Composite 26.Materials and methods:This is a prospective evaluation of 232 patients undergoing RALP between September,2019 and September,*** continence status and postoperative incontinence(pad usage)were evaluated 12 months after RALP using Expanded Prostate Cancer Index Composite 26 *** were categorized according to their surgical approach and outcome into the following groups:successful nerve sparing(NS),primarily without nerve sparing(***),and no nerve sparing by secondary resection(NNS by SR).The median levels of their questionnaire outcomes were evaluated and compared using the Wilcoxon rank sum test with continuity correction.Results:Urinary continence status 12 months after RALP differed significantly between the NS and ***(p=0.0071)and the NS and NNS by SR(p=0.0076)*** was no significant difference between the *** and NNS by SR(p=0.53)*** usage 12 months after RALP had no significant difference with regard to SR of the neurovascular bundle(p=0.14).Conclusions:Patient-reported outcomes of long-term urinary continence status seem to show no difference in postoperative conti-nence,regardless of whether a non-nerve-sparing result was planned or reached through ***,preservation of neurovascular bundle seems to lead to better long-term continence rates.
