For more than a century, hydrogen sulfide (H2S) has been regarded as a toxic gas. Recently, the understanding of the biological effects of H2S has been changed. This review surveys the growing recognition of H2S as an endogenous signaling molecule in mammals, with emphasis on its physiological and pathological pathways in the urinary system. This article reviews recent progress of basic and pharmacological researches related to endogenous H2S in urinary system, including the regulatory effects of H2S in the process of antioxidant, inflammation, cellular matrix remodeling and ion channels, and the role of endogenous H2S pathway in the pathogenesis of renal and urogenital disorders.

Plants face a range of environmental stresses, such as heat and drought, that significantly reduce their growth, development, and yield. Plants have developed complex signaling networks to regulate physiological processes and improve their ability to withstand stress. The key regulators of plant stress responses include polyamines (PAs) and gaseous signaling molecules (GSM), such as hydrogen sulfide (HS), nitric oxide (NO), methane (CH), carbon monoxide (CO), carbon dioxide (CO), and ethylene (ET).

Both hydrogen sulfide and endocannabinoids can protect the neural retina from toxic insults under in vitro and in vivo conditions. The aim of the present study was two-fold: (a) to examine the neuroprotective action of cannabinoids [methanandamide and 2-arachidonyl glycerol (2-AG)] against hydrogen peroxide (HO)-induced oxidative damage in the isolated bovine retina and (b) to evaluate the role of endogenously biosynthesized hydrogen sulfide (HS) in the inhibitory actions of cannabinoids on the oxidative stress in the bovine retina. Isolated neural retinas from cows were exposed to oxidative damage using HO (100 µM) for 10 min.

Cadmium (Cd), as one of the most toxic nonessential elements, severely prohibits plant growth and development. Hydrogen sulfide (HS) and methyl jasmonate (MeJA) play essential roles in plant response to abiotic stress. However, the potential mechanism of HS and MeJA in alleviating Cd stress in plants remains unclear.

Parkinson's disease (PD) is a complicated neurodegenerative disease that is the most prevalent severe movement disorder worldwide. The research includes studying the levels of hydrogen sulphide (H2S) and cystathionine γ-lyase (CSE) with some biochemical parameters in the serum of patients with PD in Mosul City (Iraq), which include Serotonin (SERT), dopamine (DA), sphingomyelin (SM), vitamin B12, Acetylcholine esterase (AChE), monoamine oxidase (MAO), creatine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT). Samples reached (100), which included: (40) for the Parkinson's patients group, and (60) for the control group.

Photothermal therapy (PTT) using thermal and tumor microenvironment-responsive reagents is promising for cancer treatment. This study demonstrates an effective PTT nanodrug consisting of hollow-structured, thermally sensitive polydopamine nanobowls (HPDA NB), molybdenum sulfide (MoS) nanozyme, and tirapazamine (TPZ; a hypoxia-responsive drug), with a structure of HPDA@TPZ/MoS NBs which is hereafter denoted as HPTZMoS NBs. With the Fenton-like activity, the HPTZMoS NBs in the presence of HO catalyze the formation of hydroxyl radicals, providing chemodynamic therapy (CDT) effect and deactivating glutathione.
