Growth Hormone Action as a Target in Cancer: Significance, Mechanisms and Possible Therapies.

Growth hormone (GH) is a pituitary derived endocrine hormone required for normal post-natal growth and development. Hypo or hypersecretion of endocrine GH results in two pathologic conditions, namely GH deficiency (GHD) and acromegaly. Additionally, GH is also produced in non-pituitary and tumoral tissues where it acts rather as a cellular growth factor with an autocrine/paracrine mode of action.

Sensitive Detection of Hg and l-Cysteine through Optical Asymmetry-Tuned Fluorescence Switch Off-On Behavior in N-Doped Chiral Carbon Dot.

Blue-emissive nitrogen-doped chiral carbon dots (d-NCD230 and l-NCD230) exhibiting antipodal chiroptical activity, synthesized from the thermal pyrolysis of citric acid and d/l-aspartic acid in 1:2 molar ratios, have been explored as chirality-based fluorescent turn-off/on probes for the detection of Hg and l-cysteine (l-Cys). Circular dichroism (CD) spectroscopy revealed that the chiroptical activity originates from a synergy among intrinsic chirality, chiral precursors on the NCD surface, and hybridization of lower energy levels within the embedded chiral chromophore. Quantitative analysis of optical asymmetry using the Kuhn asymmetry factor () at the CD signal of 312 nm showed a higher value for d-NCD230 (1.

Bactericidal antibiotic treatment induces damaging inflammation via TLR9 sensing of bacterial DNA.

The immunologic consequences of using bactericidal versus bacteriostatic antibiotic treatments are unclear. We observed a bacteriostatic (growth halting) treatment was more protective than a bactericidal (bacteria killing) treatment in a murine peritonitis model. To understand this unexpected difference, we compared macrophage responses to bactericidal treated bacteria or bacteriostatic treated bacteria.

The homeostasis of AtMYB4 is maintained by ARA4, HY5, and CAM7 during Arabidopsis seedling development.

Calmodulin7 (CAM7) is a key transcription factor of Arabidopsis seedling development. CAM7 works together with HY5 bZIP protein to promote photomorphogenesis at various wavelengths of light. In this study, we show that AtMYB4, identified from a yeast two-hybrid screen, physically interacts with CAM7 and works as a positive regulator of photomorphogenesis at various wavelengths of light.

Leveraging Synthetic Virology for the Rapid Engineering of Vesicular Stomatitis Virus (VSV).

Vesicular stomatitis virus (VSV) is a prototype RNA virus that has been instrumental in advancing our understanding of viral molecular biology and has applications in vaccine development, cancer therapy, antiviral screening, and more. Current VSV genome plasmids for purchase or contract virus services provide limited options for modification, restricted to predefined cloning sites and insert locations. Improved methods and tools to engineer VSV will unlock further insights into long-standing virology questions and new opportunities for innovative therapies.

Type 2 diabetes mellitus (T2DM) is a complex disease that can lead to a variety of life-threatening secondary health conditions. Current treatment strategies primarily revolve around tight glucose control that is difficult to achieve and often turns out to be dangerous due to possible hypoglycemic events. Numerous long-term studies have demonstrated that complex pathways, including low-grade inflammation due to fluctuating glucose levels, are involved in the progression of the disease and the development of secondary health conditions.

Multicellular artificial neural network-type architectures demonstrate computational problem solving.

Here, we report a modular multicellular system created by mixing and matching discrete engineered bacterial cells. This system can be designed to solve multiple computational decision problems. The modular system is based on a set of engineered bacteria that are modeled as an 'artificial neurosynapse' that, in a coculture, formed a single-layer artificial neural network-type architecture that can perform computational tasks.

Influence of Nitrogen-Doped Carbon Dots on H Radical-Mediated Au-H Formation in the Hydrogenation of 4-Nitrophenol Using NCDs-Au Nanohybrids.

The hydrogenation of 4-nitrophenol using carbon dot-stabilized gold (Au) nanoparticles is well-studied, with Au-H species known to catalyze the reaction. However, the impact of specific nitrogen moieties in nitrogen-doped carbon dots on Au-H formation and catalytic activity remains unexplored. These nitrogen species, acting as surface ligands, may influence the catalytic properties through the generation of Au-H species via H radicals.

SARS-CoV-2 M inhibitor identification using a cellular gain-of-signal assay for high-throughput screening.

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2, SARS2) is responsible for the COVID-19 pandemic and infections that continue to affect the lives of millions of people worldwide, especially those who are older and/or immunocompromised. The SARS2 main protease enzyme, M (also called 3C-like protease, 3CL), is a bona fide drug target as evidenced by potent inhibition with nirmatrelvir and ensitrelvir, the active components of the drugs Paxlovid and Xocova, respectively. However, the existence of nirmatrelvir and ensitrelvir-resistant isolates underscores the need to develop next-generation drugs with different resistance profiles and/or distinct mechanisms of action.

Derivation and Validation of an Optimal Neutrophil Gelatinase-Associated Lipocalin Cutoff to Predict Stage 2/3 Acute Kidney Injury (AKI) in Critically Ill Children.

Introduction: Acute kidney injury (AKI) defined by changes in serum creatinine (SCr), or oliguria is associated with increased morbidity and mortality in children who are critically ill. We derived and validated a clinical cutoff value for urine neutrophil gelatinase-associated lipocalin (NGAL), in a prospective multicenter study of children who were critically ill. We report the clinical performance of urine NGAL (uNGAL) to aid in pediatric AKI risk assessment.
