The Value of LC-MS/MS in Apparent Bilateral Aldosterone Suppression in Adrenal Venous Sampling for Primary Aldosteronism.

Context: Adrenal venous sampling (AVS) is recommended for subtyping primary aldosteronism (PA), however, it is unreliable when apparent bilateral aldosterone suppression (ABAS) occurs, defined as aldosterone/cortisol ratio in the adrenal vein being bilaterally lower than that in the inferior vena cava. The value of Liquid chromatography-tandem mass spectrometry (LC-MS/MS) in PA subtyping when ABAS occurs is unclear.

Objective: To determine whether LC-MS/MS can reduce the occurrence of ABAS and misdiagnosis of PA subtyping.

Vortex bifocusing of extreme ultraviolet using modified Fermat-spiral photon-sieve splitter.

Structured beams carrying orbital angular momentum (OAM) provide powerful capabilities for applications in optical tweezers, super-resolution imaging, quantum optics, and ad-vanced microparticle manipulation. However, it is challenging for generate and control the OAM beams at the extreme ultraviolet (EUV) region due to the lack of suitable wave front shaping optics arise from being limited to the strong absorption of most materials. Here, we use a modified Fermat-spiral photon-sieve splitter to simultaneously generate two focused doughnut beams with opposite helical phase.

Regio- and Stereoselective β-Sulfonylamination of Alkynes via Photosensitized Bifunctional N-S Bond Homolysis.

Nitrogen central radicals (NCRs) are versatile synthetic intermediates for creating functional nitrogen-containing molecules. Herein, a photosensitized β-sulfonylamination of terminal alkynes as well as acetylene has been established by employing -sulfonyl heteroaromatics as bifunctional reagents (BFRs) to efficiently deliver versatile ()-β-sulfonylvinylamines with excellent regio- and stereoselectivities. Mechanistic studies suggest a base-accelerated energy transfer (EnT) photocatalysis involving aromatic NCR formation, radical addition to alkynes, and sulfonylation processes.

Comparison of Different Diagnostic Criteria of 68Ga-Pentixafor PET/CT for the Classification of Primary Aldosteronism.

Context: 68Ga-Pentixafor positron emission tomography/computed tomography (PET/CT) is an emerging method for the classification diagnosis primary aldosteronism (PA). However, the diagnosis criteria are still controversial.

Comparison of a chemiluminescence immunoassay with LC-MS/MS in the determination of the plasma aldosterone concentration in patients with impaired renal function.

Purpose: Compared with chemiluminescence immunoassay (CLIA), the quantification of the plasma aldosterone concentration (PAC) via liquid chromatography-tandem mass spectrometry (LC-MS/MS) yields lower values. The extent to which this difference is exacerbated by a reduced glomerular filtration rate (eGFR) is unclear. Therefore, this study aims to assess the impact of renal insufficiency on PAC as measured by CLIA using LC-MS/MS as the reference method.

Targeting of tumoral NAC1 mitigates myeloid-derived suppressor cell-mediated immunosuppression and potentiates anti-PD-1 therapy in ovarian cancer.

Epithelial ovarian cancer (EOC) is the most common type of ovarian cancer with a low rate of response to immunotherapy such as immune checkpoint blockade (ICB) therapy. Here, we report that nucleus accumbens-associated protein 1 (NAC1), a putative driver of EOC, has a critical role in immune evasion. We showed in murine ovarian cancer models that depleting or inhibiting tumoral NAC1 reduced the recruitment and immunosuppressive function of myeloid-derived suppressor cells (MDSCs) in the tumor microenvironment (TME), led to significant increases of cytotoxic tumor-infiltrating CD8+ T cells, and promoted antitumor immunity and suppressed tumor progression.

Perirenal fat and chronic kidney disease in type 2 diabetes: The mediation role of afferent arteriolar resistance.

Aim: Perirenal fat (PRF) is an independent predictor for chronic kidney disease (CKD) in type 2 diabetes mellitus (T2DM) patients. Previous studies speculated that PRF may promote renal dysfunction through affecting renal hemodynamics. To verify this hypothesis, we studied the relationship between PRF and renal hemodynamics in T2DM.

Silk-enriched hydrogels with ROS-scavenging dendrimers for advanced wound care.

This study explores the development of novel hydrogel composites for wound care, incorporating silk fibroin and reactive oxygen species (ROS)-scavenging dendrimers into a polyvinyl alcohol (PVA) matrix. Utilizing ionizing gamma radiation, we fabricated pristine PVA, silk-PVA (SPVA) binary, and dendrimer-silk-PVA (DSPVA) ternary hydrogel composites, with their composition confirmed via UV-visible absorption spectroscopy. Fourier-transform infrared (FTIR) and Raman spectroscopy analyses indicated complex interactions between the hydrogel components, enhancing their structural and biocompatible properties.

We use observational and genetic data from the UK Biobank, obtaining GWAS summary data, eQTL analysis data, TCGA data, and GTEx data from public datasets.

Excess Dally-like Induces Malformation of Legs.

Glypicans are closely associated with organ development and tumorigenesis in animals. Dally-like (Dlp), a membrane-bound glypican, plays pivotal roles in various biological processes in . In this study, we observed that an excess of Dlp led to the malformation of legs, particularly affecting the distal part.

Effector MoSDT1 enhances Magnaporthe oryzae virulence and plays a dual role in regulating rice defense.

C2H2 zinc effectors are a class of pathogen proteins that play a dual role in plant-pathogen interactions, promoting pathogenicity and enhancing plant defense. In our previous research, we identified Magnaporthe oryzae Systemic Defense Trigger 1 (MoSDT1) as a C2H2 zinc effector that activates rice (Oryza sativa) defense when overexpressed in rice. However, its regulatory roles in pathogenicity and defense require further investigation.

Ga-pentixafor PET/CT in the localization diagnosis of primary aldosteronism concurrent subclinical cushing's syndrsome: two case reports.

Purpose: Adrenal venous sampling (AVS) is recommended for subtyping primary aldosteronism (PA). However, in cases of PA, concurrent subclinical Cushing's syndrome (SCS) has the potential to confound AVS results. Pentixafor, a CXC chemokine receptor type 4-specific ligand, has been reported as a promising marker to evaluate functional nature of adrenal adenomas.

The Marssonina rosae effector MrSEP43 suppresses immunity in rose by targeting the orphan protein RcBROG.

Rose black spot disease, caused by Marssonina rosae (syn. Diplocarpon rosae), is one of the most widespread diseases of field-grown roses worldwide. Pathogens have been found to interfere with or stimulate plant immune responses by secreting effectors.

Marein, a novel natural product for restoring chemo-sensitivity to cancer cells through competitive inhibition of ABCG2 function.

The pivotal roles of ATP-binding cassette (ABC) transporters in drug resistance have been widely appreciated. Here we report that marein, a natural product from Coreopsis tinctoria Nutt, is a potent chemo-sensitizer in drug resistant cancer cells overexpressing ABCG2 transporter. We demonstrate that marein can competitively inhibit efflux activity of ABCG2 protein and increase the intracellular accumulation of the chemotherapeutic drugs that belong to substrate of this transporter.

Indole-3 acetic acid negatively regulates rose black spot disease resistance through antagonizing the salicylic acid signaling pathway via jasmonic acid.

IAA cooperates with JA to inhibit SA and negatively regulates rose black spot disease resistance. Black spot disease caused by the fungus Marssonina rosae is the most prevalent and severe ailment in rose cultivation, leading to the appearance of black spots on leaves and eventual leaf fall, significantly impacting the utilization of roses in gardens. Salicylic acid (SA) and jasmonic acid (JA) are pivotal hormones that collaborate with indole-3 acetic acid (IAA) in regulating plant defense responses; however, the detailed mechanisms underlying the induction of black spot disease resistance by IAA, JA, and SA remain unclear.

Cooperative correction method for distortion and dispersion of deflected field of view in Risley-prism bionic-human-eye imaging systems.

The Risley-prism imaging system (RPIS) is a powerful way to achieve bionic human eye imaging with great advantages on large field of view (FOV) and variable resolution imaging owing to the autonomous controlled deflection of light. But the imaging dispersion originating from nonlinear and uneven light deflection results in limited imaging wavelength that seriously hinders its application. The existing solutions for imaging dispersion mainly rely on the hardware, which generally has bulky structure and limited improvement on image.
