Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Recent developments in the chemistry and enzyme inhibitory activity of fused thiazoles and thiadiazoles

Vietnam Journal of Chemistry, EarlyView.
Abstract The combination of cyclization reactions of thiadiazoles and benzothiazoles with Pd‐catalyzed cross‐coupling reactions provided a convenient synthesis of annulated, fluorinated and non‐fluorinated heterocycles, such as 1,3,4‐thiadiazolo[3,2‐a]pyrimidin‐5‐ones, benzothiazolo[3,2‐a]pyridimidin‐4‐ones, benzothiazolo[2,3‐b]quinazolin‐12‐ones and ...

GAS‐J, a User‐Friendly Browser Application for Genome Assembly, emm‐Typing, MLST Typing, and Virulence Factor Gene Detection of Streptococcus pyogenes

Microbiology and Immunology, EarlyView.
ABSTRACT Clinical isolates of Streptococcus pyogenes are usually classified using emm and multilocus sequence typing (MLST). Recently, whole genome sequencing (WGS) has been employed for emm typing and MLST analysis. WGS data provides additional information on the presence of virulence factor genes.

Lower time‐averaged serum uric acid was associated with increased mortality in peritoneal dialysis patients

Therapeutic Apheresis and Dialysis, Volume 29, Issue 3, Page 479-490, June 2025.
Abstract Background The relationship between time‐averaged serum uric acid (TA‐SUA) levels and prognosis in peritoneal dialysis (PD) patients are rarely discussed. Methods This was a retrospective cohort study. PD patients recruited from January 1, 2011, to December 31, 2020, were included.

MMF Is an Effective and Safer Treatment Options for Treatment‐Naïve Patients With Autoimmune Hepatitis Compared to Azathioprine: A Systematic Review and Meta‐Analysis

Journal of Digestive Diseases, EarlyView.
Mycophenolate mofetil (MMF) demonstrates superior efficacy and tolerability compared to azathioprine (AZA) in treatment‐naïve autoimmune hepatitis (AIH) patients. Meta‐analysis of five studies reveals higher complete biochemical response rates, increased Corticosteroid withdrawal rate, and fewer gastrointestinal side effects with MMF.

Downregulation of NAD Kinase Expression in β‐Cells Contributes to the Aging‐Associated Decline in Glucose‐Stimulated Insulin Secretion

Aging Cell, Volume 24, Issue 4, April 2025.
Adequate NADK/NADK2 level is essential to the proper functioning of redox and folate cycles and the purine biosynthesis pathway, and as well as maintenance of GSIS response. During aging, diminished NADK/NADK2 expression alters the metabolic status quo, increasing AICAR production. The latter activates AMPK and suppresses GSIS.
