and mRNA expression-based risk stratification of acute Myeloid Leukemia.

Leuk Res Rep

December 2024

Independent Researcher, Gimpo-si, Gyeonggi-do 10090, South Korea.

Prognostication of acute myeloid leukemia (AML) at initial diagnosis relies on identification of pre-determined underlying genetic abnormalities. Nevertheless, the disease course of AML remains highly unpredictable and robust reliable prognostic biomarkers for newly diagnosed AML are lacking. We retrospectively explored two publicly available AML RNA-Seq datasets and found that inferior overall survival was associated with high- and low- transcript levels (" / ") compared to low- and high- transcript levels (" / ") in adult AML patients, with a hazard ratio for death of at least 2.

Background: Point-of-care testing (POCT) is a valuable diagnostic approach for identifying pathogens such as Group A Streptococcus (GAS) and influenza. Early detection through POCT allows for timely initiation of appropriate treatments improving public health outcomes and minimizing antibiotic misuse. Community pharmacists are well positioned to offer POCT and treatment, but they face significant system level barriers to widespread implementation and reach.

The associations between cardiovascular and pain responses to a cold pressor test differ between males and females.

Eur J Appl Physiol

January 2025

Department of Physical Therapy & Rehabilitation Science, Carver College of Medicine, the University of Iowa, Iowa City, IA, 52242, USA.

Nociceptors contribute to the cardiovascular responses during a cold pressor test (CPT). While these responses are lower in females, data suggest that they perceive the CPT as more painful. Thus, we examined sex differences in associations between pain and cardiovascular responses to a CPT (Aim 1) as well as differences between females using (OC), and not using (NC), an oral contraceptive (Aim 2).

Clear cell renal cell carcinoma (ccRCC) poses a significant global health challenge as its incidence continues to rise, resulting in a substantial annual mortality rate. Major clinical challenges to current ccRCC treatments include high drug-resistance rates as well as dose-limiting adverse events; underlining the need to identify additional 'druggable' targets. TGF-β1, VEGF, and PD-L1 are potential therapeutic targets in ccRCC.

Comput Biol Med

January 2025

Department of Electrical and Computer Engineering, University of Florida, Gainesville, FL, 32610, United States; Department of Medicine, University of Florida, Gainesville, FL, 32610, United States; Department of Health Outcomes and Biomedical Informatics, University of Florida, Gainesville, FL, 32610, United States; Intelligent Clinical Care Center, University of Florida, Gainesville, FL, 32610, United States. Electronic address:

Retinal image registration is essential for monitoring eye diseases and planning treatments, yet it remains challenging due to large deformations, minimal overlap, and varying image quality. To address these challenges, we propose RetinaRegNet, a multi-stage image registration model with zero-shot generalizability across multiple retinal imaging modalities. RetinaRegNet begins by extracting image features using a pretrained latent diffusion model.

Neurons require high amounts energy, and mitochondria help to fulfill this requirement. Dysfunctional mitochondria trigger problems in various neuronal tasks. Using the neuromuscular junction (NMJ) as a model synapse, we previously reported that Mitochondrial Complex I (MCI) subunits were required for maintaining NMJ function and growth.

Neurotrophic factors are critical for establishing functional connectivity in the nervous system and sustaining neuronal survival through adulthood. As the first neurotrophic factor purified, nerve growth factor (NGF) is extensively studied for its prolific role in axon outgrowth, pruning, and survival. Applying NGF to diseased neuronal tissue is an exciting therapeutic option and understanding how NGF regulates local axon susceptibility to pathological degeneration is critical for exploiting its full potential.

Acetyl CoA synthetases (ACS) have emerged as drug targets for the treatment of cancer, metabolic diseases as well as fungal and parasitic infections. Although a variety of small molecule ACS inhibitors have been discovered, the systematic optimization of these molecules has been slowed by a lack of structural information regarding their mechanism of inhibition. Through a chemical genetic-based, synthetic lethal screen of the human fungal pathogen , we identified an isoxazole-based ACS inhibitor with antifungal activity and exquisite selectivity for the Acs1 relative to human ACSS2 as well as other fungal ACSs.

Potentiating the effect of immunotherapy in pancreatic cancer using gas-entrapping materials.

Immune checkpoint inhibitors (ICIs) show limited success in treating pancreatic ductal adenocarcinoma (PDAC), largely due to immune evasion mechanisms, including downregulating expression of major histocompatibility complex class I (MHC-I). Our retrospective analysis demonstrated that smoking - a state of elevated CO exposure - is correlated with increased MHC I expression in pancreatic tumors. Here we tested our hypothesis that introducing exogenous CO augments the anti-cancer effects of immunotherapy.

The Impact of Cell-Intrinsic STAT6 Protein on Donor T Cell-Mediated Graft-Versus-Tumor Effect.

Int J Mol Sci

December 2024

Department of Internal Medicine, Division of Gastroenterology and Hepatology, Carver College of Medicine, University of Iowa, Iowa City, IA 52242, USA.

Bone marrow transplantation (BMT) is mainly performed to restore an anti-tumor immune response, called the graft-versus-tumor (GVT) effect, against leukemia, myeloma and lymphoma. This GVT reactivity is driven by donor T cells, and it can also cause lethal graft-versus-host disease (GVHD). We previously demonstrated that the colonization of mice with helminths preserves the GVT response while suppressing GVHD.

Plants adapted to life on land by developing diverse anatomical features across lineages. The molecular basis of these innovations often involves the emergence of new genes or establishing new connections between conserved elements, though evidence for evolutionary genetic circuit rewiring remains scarce. Here, we show that the thermospermine-dependent pathway regulating vascular cell proliferation in Arabidopsis thaliana operates as two distinct modules with different functions in the bryophyte Marchantia polymorpha.

We describe the novel occurrence of a adenocarcinoma involving the trachea, with distinct solid and glandular components, in a 34-year-old patient. We illustrate its morphological and immunophenotypic features and describe the molecular finding of an EWSR1::BEND2 gene fusion detected by next-generation sequencing (NGS). We discuss the findings in comparison to BEND2-fusion associated neoplasms reported in the head and neck region in the literature to date.

Key Laboratory of Ministry of Education for Water Quality Security and Protection in Pearl River Delta, School of Environmental Science and Engineering, Guangzhou University, Guangzhou 510006, China.

Recently, 7-diethylamino-4-methylcoumarin (DEAMC) has been identified as a potent antiandrogenic compound in the surface water; however, little is known about the antiandrogenic potentials of other synthetic coumarins and their occurrence in the aquatic ecosystem. In this study, for the first time, we observed that 7-dimethylamino-4-methylcoumarin (DAMC) elicited androgen receptor (AR) antagonistic activity with a 50% inhibitory concentration (IC) of 1.46 µM, which is 14.

Sensitivity of Acoustic Voice Quality Measures in Simulated Reverberation Conditions.

Bioengineering (Basel)

December 2024

Department of Communication Sciences and Disorders, University of Iowa, Iowa City, IA 52242, USA.

Room reverberation can affect oral/aural communication and is especially critical in computer analysis of voice. High levels of reverberation can distort voice recordings, impacting the accuracy of quantifying voice production quality and vocal health evaluations. This study quantifies the impact of additive simulated reverberation on otherwise clean voice recordings as reflected in voice metrics commonly used for voice quality evaluation.

Introduction: Prior analysis of children with grade 3 and 4 congenital hydronephrosis demonstrated that renal medullary pyramidal thickness (PT) is predictive of subsequent pyeloplasty (area under the curve [AUC] = 0.78). The objective of this study was to further analyze the utility of sonographic measurements including PT, anteroposterior pelvic diameter (APD), and renal length with an expansion of the number of infants with hydronephrotic kidneys including grades 2, 3, and 4 hydronephrosis.
