The Purple Tomato Story; From Laboratory Bench to the Consumer.

ACS Food Sci Technol

January 2025

John Innes Centre, Norwich Research Park, Norwich NR4 7UH, U.K.

A world apart from academic research, the path from developing a polyphenol-rich crop to a product available to consumers is not one taken by many research scientists. Here we review the steps taken to commercialize anthocyanin-enriched purple tomatoes in the USA. In describing some of the difficulties encountered and the work that was necessary for a successful commercial launch of a new biotech product, we hope to encourage others to believe that there is a viable route to market, and an appetite for polyphenol-enriched foods that can protect health.

Colony-stimulating factor 1 receptor (CSF1R) is almost exclusively expressed on microglia in the human brain and thus, has promise as a biomarker for imaging microglia density as a proxy for neuroinflammation. [C]CPPC is a radiotracer with selective affinity to CSF1R, and has been evaluated for in-human microglia PET imaging. The flourine-18 labeled CPPC derivative, 5-cyano-N-(4-(4-(2-[F]fluoroethyl)piperazin-1-yl)-2-(piperidin-1-yl)phenyl)furan-2-carboxamide ([F]FCPPC), was previously synthesized, however, with a low radiochemical yield using manual radiosynthesis.

The chemical reduction of a pyracylene-hexa--hexabenzocoronene-(HBC)-fused nanographene TPP was investigated with K and Rb metals to reveal its multi-electron acceptor abilities. The reaction of TPP with the above alkali metals, monitored by UV-vis-NIR and H NMR spectroscopy, evidenced the stepwise reduction process. The use of different solvents and secondary ligands enabled isolation of single crystals of three different reduced states of TPP with 1, 2, and 3 electrons added to its π-system.

Mycobacterial hemerythrin-like proteins (HLPs) are important for the survival of pathogens in macrophages. Their molecular mechanisms of function remain poorly defined but recent studies point to their possible role in nitric oxide (NO) scavenging. Unlike any nonheme diiron protein studied so far, the diferric HLP from (-HLP) reacts with NO in a multistep fashion to consume four NO molecules per diiron center.

Background: The gold standard for crystal arthritis diagnosis relies on the identification of either monosodium urate (MSU) or calcium pyrophosphate (CPP) crystals in synovial fluid. With the goal of enhanced crystal detection, we adapted a standard compensated polarized light microscope (CPLM) with a polarized digital camera and multi-focal depth imaging capabilities to create digital images from synovial fluid mounted on microscope slides. Using this single-shot computational polarized light microscopy (SCPLM) method, we compared rates of crystal detection and raters' preference for image.

Background: Bedside thoracic ultrasound (US) offers numerous advantages over chest X-ray (CXR) for identification of recurrent pneumothoraces (PTX) after tube thoracostomy (TT) removal. Technologic advancements have led to the development of hand-held devices capable of producing high-quality images termed ultra-portable US (UPUS). We hypothesized that UPUS would be as successful as CXR in detecting post-TT removal PTX and would be preferred by patients.

Wildland fire entrainment: The missing link between wildland fire and its environment.

PNAS Nexus

January 2025

Southern Research Station, US Forest Service, 320 Green Street, Athens, GA 30602, USA.

Wildfires are growing in destructive power, and accurately predicting the spread and intensity of wildland fire is essential for managing ecological and societal impacts. No current operational models used for fire behavior prediction resolve critical fire-atmospheric coupling or nonlocal influences of the fire environment, rendering them inadequate in accounting for the range of wildland fire behavior scenarios under increasingly novel fuel and climate conditions. Here, we present a new perspective on a dominant fire-atmospheric feedback mechanism, which we term wildland fire entrainment (WFE).

Mass shootings durably increase the sale of alcohol in American communities.

PNAS Nexus

January 2025

Department of Psychology, University of Wisconsin-Madison, 1202 W Johnson St, Madison, WI 53706, USA.

Mass shootings are devastating events. Communities can cope with the ensuing trauma in a number of ways, including changing their behavioral patterns. Using point-of-sale data from 35,000 individual retailers, including more than half of all American grocery and drugstore purchases, and all American mass shootings from 2006 to 2019, we find, in a set of two-way fixed-effects counterfactual analyses, that a mass shooting in a given community (the area covered by the ZIP-3 code) predicts a significant increase in the sales of alcohol that lasts at least 2 years past the shooting.

We present the case of a 23-year-old male who experienced vision loss in his left eye 15 months after undergoing bilateral transepithelial photorefractive keratectomy (T-PRK). Despite the absence of any significant preoperative topographical risk factors in either eye, corneal ectasia was later confirmed in the left eye, while the right eye remained normal. Subtle asymmetry in topometric indices and a borderline high Index of vertical asymmetry (IVA) reading suggested the possibility of early subclinical keratoconus, potentially increasing the risk of post-refractive ectasia.
