Article Abstract
Hydrogen sulfide (HS) gas plays a significant role in biological regulation. With advancements in technology, HS has been discovered across diverse fields, necessitating a comprehensive understanding of its physiological functions through monitoring changes in HS within complex environments and physiological processes. In this study, we designed a phosphofluorene-based conjugate probe PPF-CDNB with an asymmetric π-conjugated phosphine structure and utilized dinitrophenyl ether as the recognition site for HS. PPF-CDNB exhibited exceptional resistance to interference and demonstrated stability over a broad pH range (3.0-10.0), making it suitable for various environmental conditions. Intracellular experiments revealed that PPF-CDNB effectively monitored both endogenous and exogenous levels of HS.

Purpose: To evaluate the impact of MRP inhibition by MK571 on prostate hypercontractility in diet-induced obesity, based on the hypothesis that this intervention enhances intracellular cAMP and cGMP signaling.
Methods: Adult C57BL/6 mice were divided into three groups: (i) lean, (ii) obese, and (iii) obese + MK571 (5 mg/kg/day, 14 days). The prostate was isolated for immunohistochemistry, biochemistry and functional assays.
Complex-variable MP2 theory applied to core-vacant states for the computation of Auger spectra.

We model Auger spectra using second-order Møller-Plesset perturbation (MP2) theory combined with complex-scaled basis functions. For this purpose, we decompose the complex MP2 energy of the core-hole state into contributions from specific decay channels and propose a corresponding equation-of-motion (EOM) method for computing the doubly ionized final states of Auger decay. These methods lead to significant savings in computational cost compared to our recently developed approaches based on coupled-cluster theory [F.
