Air-drying pretreatment effect on soil enzymatic activity
Plant, Soil and Environment, 2017 Air-drying of soil samples is a common practice for all-purpose soil testing. However, it may cause the cessation of microbial activity changing the biochemical attributes.

Riding the sulfur cycle - metabolism of sulfonates and sulfate esters in Gram-negative bacteria [PDF]
, 2017 Sulfonates and sulfate esters are widespread in nature, and make up over 95% of the sulfur content of most aerobic soils. Many microorganisms can use sulfonates and sulfate esters as a source of sulfur for growth, even when they are unable to metabolize ...

Enhancing the Steroid Sulfatase Activity of the Arylsulfatase from Pseudomonas aeruginosa [PDF]
, 2018 Steroidal sulfate esters play a central role in many physiological processes. They serve as the reservoir for endogenous sex hormones and form a significant fraction of the steroid metabolite pool.

Expanding the genetic landscape of Usher syndrome type IV caused by pathogenic ARSG variants
Clinical Genetics, Volume 107, Issue 1, Page 44-55, January 2025.Mutations in ARSG are a very rare cause of Usher disease, assigned as “Usher type IV.” We identified 13 new subjects with mutations in ARSG, provide a clinical description of the subjects, and characterized the newly identified variants. Abstract Usher syndrome (USH) is the most common cause of deafblindness.

Mammalian sulfo-conjugate metabolism [PDF]
, 1987 Sulfoconjugates occur ubiquitously as sulfopolysaccharides, sulfolipids and sulfoproteins. A variety of sulfotransferases catalyze the sulfation process with 3'- phosphoadenosine 5'-phosphosulfate as the sulfate donor.

Journal of Chemistry, Volume 2025, Issue 1, 2025.The formation of biofilms occurs due to a group of bacteria gathering together. The increasing of cell density will stimulate chemical signals for bacteria to communicate through quorum sensing system. Quorum sensing plays a role for competition, virulence, resistance, and pathogenesis. Quorum sensing produces signaling response called as autoinducers.

P-selectin mediates metastatic progression through binding to sulfatides on tumor cells [PDF]
, 2017 Hematogenous carcinoma metastasis is associated with tumor cell emboli formation, which is now known to be facilitated by selectins. P-selectin-mediated interactions of platelets with cancer cells are based mostly on mucin- and glycosaminoglycan-type ...

Hair follicle sulfotransferase activity and effectiveness of oral minoxidil in androgenetic alopecia
Journal of Cosmetic Dermatology, Volume 23, Issue 11, Page 3767-3773, November 2024.Abstract Background Androgenetic alopecia (AGA) is common. While topical minoxidil remains the only FDA‐approved therapeutic for AGA, its efficacy is limited in stimulating clinically significant hair regrowth over the longer term. Oral minoxidil, which is used off‐label, is a promising alternative; however, its effectiveness and underlying mechanisms ...
