Premise: The use of hybrid breeding systems to increase crop yields has been the cornerstone of modern agriculture and is exemplified in the breeding and improvement of cultivated sunflower (Helianthus annuus). However, it is poorly understood what effect supporting separate breeding pools in such systems, combined with continued selection for yield, may have on leaf ecophysiology and specialized metabolite variation.

Methods: We analyzed 288 lines of cultivated H.

Lysine deacetylases (KDACs or HDACs) are metal-dependent enzymes that regulate lysine acetylation, a post-translational modification that is present on thousands of human proteins, essential for many cellular processes, and often misregulated in diseases. The selective inhibition of KDACs would allow for understanding of the biological roles of individual KDACs and therapeutic targeting of individual enzymes. Recent studies have suggested that purportedly specific KDAC inhibitors have significant off-target binding, but the biological consequences of off-target binding were not evaluated.

Article Synopsis
  • Researchers aimed to create and validate a prediction score for futile recanalization (FR) in patients with low Alberta Stroke Program Early Computed Tomography Scores (ASPECTS) who underwent endovascular thrombectomy (EVT) for large vessel occlusions (LVO).
  • The study analyzed data from 219 patients with anterior circulation LVO and identified key predictors of FR, resulting in the development of the SNAP score, which considers factors like the site of occlusion and patient age.
  • The SNAP score successfully predicted FR with an area under the curve of 0.79 in both training and validation cohorts, indicating its potential usefulness for guiding expectations in patients undergoing EVT for severe strokes.

Article Synopsis
  • Eye-tracking studies are useful for understanding language disorders like aphasia, but often suffer from small sample sizes, making results less generalizable; webcam-based tracking could address this issue.
  • In a study, patients with post-stroke aphasia and matched controls performed sentence-picture matching tasks both in-lab and online to compare the sensitivity of both tracking methods.
  • Results indicated that web-based tracking can effectively detect group differences in language processing in aphasia, although it showed a delay compared to in-lab tracking, suggesting further validation is needed for this promising technique.

Membrane Separations in Biomass Processing.

Chempluschem

October 2024

Governor's Chair for Biorefining, Joint Institute for Biological Sciences, Biosciences Division, Oak Ridge National Laboratory, 1 Bethel Valley Road, Oak Ridge, TN 37831.

The development of integrated biorefineries and the greater utilization of biomass resources to reduce dependence on fossil fuel-derived products require research emphasis not just on conversion strategies but also on improving separations associated with biorefining. A significant roadblock towards developing biorefineries is the lack of effective separation techniques evidenced by the relative deficiency of literature in this area. Additionally, high conversion yields may only be realized if effective separations generate feedstock of sufficient purity - this makes research into biomass conversion strategies all the more critical.

Western equine encephalitis virus (WEEV) is a mosquito-borne arbovirus (genus , family ) that has re-emerged in South America in late 2023, causing severe disease in both horses and humans after a nearly 40-year intermission period. We here describe the virological, serological, pathological, and molecular features of WEEV infection in horses during the 2023-2024 outbreak in Argentina. WEEV-infected horses developed neurological signs with mild to severe encephalitis associated with minimal to abundant WEEV-infected cells, as demonstrated by WEEV-specific in situ hybridization.

Impairments in synaptic dynamics and stability are observed both in neurodegenerative disorders and in the healthy aging cortex, which exhibits elevated dendritic spine turnover and decreased long-term stability of excitatory connections at baseline, as well as an altered response to plasticity induction. In addition to the discrete gain and loss of synapses, spines also change in size and strength both during learning and in the absence of neural activity, and synaptic volume has been associated with stability and incorporation into memory traces. Furthermore, intrinsic dynamics, an apparently stochastic component of spine volume changes, may serve as a homeostatic mechanism to prevent stabilization of superfluous connections.

Personalized healthcare is becoming increasingly popular given the vast heterogeneity in disease manifestation between individuals. Many commonly encountered diseases within cardiology are multifactorial in nature and disease progression and response is often variable due to environmental and genetic factors influencing disease states. This makes accurate early identification and primary prevention difficult in certain populations, especially young patients with limited Atherosclerotic Cardiovascular Disease (ASCVD) risk factors.

In defense of in vitro fertilization: time to get involved in state-level advocacy!

Fertil Steril

December 2024

Department of Obstetrics and Gynecology, Louisiana State University Health- Shreveport, Shreveport, Louisiana; Department of Obstetrics and Gynecology, University of Mississippi Medical Center, Jackson, Mississippi; Positive Steps Fertility, Madison, Mississippi.

We share experiences in advocating to defend in vitro fertilization (IVF) in Virginia, Missouri, and Mississippi; provide historical context on the "Personhood" anti-IVF movement; and discuss why "embryo donation" is a more accurate term than "embryo adoption." Some individuals and communities have a deeply held belief that a fertilized oocyte is a very early human life, and we will likely never change their minds. In the fertility community, most providers consider embryos to be an important part of the continuum between gametes (sperm and eggs) to live birth.
