Synergistic effects of GmLFYa and GmLFYb on Compound Leaf Development in Soybean.

Legume leaves exhibit diverse compound forms, with various regulatory mechanisms underlying the development. The transcription factor-encoding KNOXI genes are required to promote leaflet initiation in most compound-leafed angiosperms. In non-IRLC (inverted repeat-lacking clade) legumes, KNOXI are expressed in compound leaf primordia but not in others (IRLC).

Quantification of ivermectin in veterinary products consumed off-label as a treatment for COVID-19.

The COVID-19 pandemic caused global pandemonium, and due to an unprecedented global response, the popularity and use of (veterinary) ivermectin, amongst many other conceivable 'treatments', experienced a meteoric rise. Ivermectin is a macrocyclic lactone compound belonging to the avermectin drug class and is a registered medicine in many countries, although the most common use is as veterinary medicine. In this study, a fast HPLC method was developed and validated for the quantification of ivermectin in veterinary products that were used off-label by a substantial number of people during COVID-19.

TIM-1 attenuates airway mucus hypersecretion and inflammation induced by cigarette smoke via the PI3K/Akt signaling pathway.

Cigarette smoke extract (CSE)-induced airway mucus hypersecretion and inflammation are prominent features of chronic obstructive pulmonary disease (COPD). As a factor associated with inflammation regulation, T cell immunoglobulin and mucin domain-1 (TIM-1) is found to be involved in various inflammatory disorders such as asthma and COPD. In this study, the GEO database provides two human COPD gene expression datasets (GSE67472, n = 62) along with the relevant controls (n = 43) for differentially expressed gene (DEG) analyses.

Georgios Photeinos and his (1835) published in Ottoman Smyrna.

The , authored by Ottoman pharmacist Georgios Photeinos and published in 1835 in Smyrna (modern-day Izmir, T??rkiye), is a historically significant yet largely overlooked work in 19th-century pharmaceutical literature. At a time when modern pharmaceutical resources in Greek were scarce, Photeinos sought to address this gap by creating a comprehensive pharmacopoeia that extensively drew from the Austrian Pharmacopoeia, as well as French and Latin sources. Although he initiated the project around 1804, political upheavals delayed its completion by more than three decades.

Decoding the Molecular Enigma Behind Asbestos and Fibrous Nanomaterial-induced carcinogenesis.

Objectives: Natural fibrous mineral, asbestos, has been useful in industry for many centuries. In the 1960's, epidemiology had recognized the association between asbestos exposure and mesothelioma and the IARC designated all kinds of asbestos as Group 1 in 1987. However, various scientific enigmas remained regarding the molecular mechanisms of asbestos-induced mesothelial carcinogenesis.

Validity of one-time phantomless patient-specific quality assurance in proton therapy with regard to the reproducibility of beam delivery.

Background: Patient-specific quality assurance (PSQA) is a crucial yet resource-intensive task in proton therapy, requiring special equipment, expertise and additional beam time. Machine delivery log files contain information about energy, position and monitor units (MU) of all delivered spots, allowing a reconstruction of the applied dose. This raises the prospect of phantomless, log file-based QA (LFQA) as an automated replacement of current phantom-based solutions, provided that such an approach guarantees a comparable level of safety.

Modeling absorbed alpha particle dose from diffusing alpha-emitters radiation therapy in changing tissue volumes.

Background: Diffusing alpha-emitters Radiation Therapy ("Alpha DaRT") is a promising new radiation therapy modality for treating bulky tumors. Ra-carrying sources are inserted intratumorally, producing a therapeutic alpha-dose region with a total size of a few millimeter via the diffusive motion of Ra's alpha-emitting daughters. Clinical studies of Alpha DaRT have reported 100% positive response (30%-100% shrinkage within several weeks), with post-insertion swelling in close to half of the cases.

Optimization of x-ray dark-field CT for human-scale lung imaging.

Background: X-ray grating-based dark-field imaging can sense the small angle scattering caused by object's micro-structures. This technique is sensitive to the porous microstructure of lung alveoli and has the potential to detect lung diseases at an early stage. Up to now, a human-scale dark-field CT (DF-CT) prototype has been built for lung imaging.

Histone Modifications and DNA Methylation in Psoriasis: A Cellular Perspective.

In recent years, epigenetic modifications have attracted significant attention due to their unique regulatory mechanisms and profound biological implications. Acting as a bridge between environmental stimuli and changes in gene activity, they reshape gene expression patterns, providing organisms with regulatory mechanisms to respond to environmental changes. A growing body of evidence indicates that epigenetic regulation plays a crucial role in the pathogenesis and progression of psoriasis.

Comparative Analysis of 4NQO- and Ethanol-Induced Oral Epithelial Dysplasia and Oral Squamous Cell Carcinoma in Male and Female Mice: Association With Peripheral Blood Inflammatory Markers.

Background: Considering that peripheral blood biomarkers are prognostic predictors for several human tumors, this study aimed to comparatively analyze the association of hematological alterations with the incidence of epithelial dysplasia (ED) and oral squamous cell carcinoma (OSCC) in male and female mice treated with 4-nitroquinoline-N-oxide (4NQO) and ethanol (EtOH).
