BACKGROUND We evaluated the predictive ability of cystatin C and creatinine-based estimations of glomerular filtration rate (eGFR), including the Chronic Kidney Disease-Epidemiology (CKD-EPI) equation, in acute coronary syndrome (ACS) patients with (STE-ACS) or without (NSTE-ACS) ST elevation in a large contemporary ACS population. METHODS Concentrations of cystatin C and creatinine, as well ...

BACKGROUND We aimed to evaluate the performance of serum cystatin C-based equations in calculating the glomerular filtration rate (GFR) in patients with varying stages of chronic kidney disease (CKD). METHODS Serum cystatin C and creatinine levels were measured in 615 CKD patients. The CKD stage was determined by the creatinine-based estimated GFR (eGFR) equation using the four-variable abbre...

Nodulation, nodule development and senescence directly affects nitrogen fixation efficiency, and previous studies have shown that inhibition of some cysteine proteases delay nodule senescence, so their nature inhibitors, cystatin genes, are very important in nodulation, nodule development, and senescence. Although several cystatins are actively transcribed in soybean nodules, their exact roles ...

Cystatin F is a cysteine peptidase inhibitor which, unlike other cystatin family members, is targeted to endosomal/lysosomal compartments. It is synthesized as an inactive disulfide-linked dimer which is then converted to an active monomer by proteolytic cleavage of 15 N-terminal residues. Cystatin F has been suggested to regulate the cytotoxicity of natural killer (NK) cells by inhibiting the ...

BACKGROUND Cystatin C has emerged as a new biomarker of renal function that has been found to predict adverse cardiovascular outcomes, especially heart failure (HF). Evidence of the usefulness of cystatin C in patients with heart failure with preserved ejection fraction (HFPEF) remains sparse. It is hypothesized that serum cystatin C levels in HFPEF has prognostic value. METHODS AND RESULTS C...

OBJECTIVE Acute kidney injury (AKI) after cardiac surgery procedures is associated with poor patient outcomes. Cystatin C as a marker for renal failure has been shown to be of prognostic value; however, a wide range of its predictive accuracy has been reported. The aim of the study was to evaluate whether the measurement of pre- and postoperative serum cystatin C improves the prediction of AKI....

Cystatin D is an inhibitor of lysosomal and secreted cysteine proteases. Strikingly, cystatin D has been found to inhibit proliferation, migration, and invasion of colon carcinoma cells indicating tumor suppressor activity that is unrelated to protease inhibition. Here, we demonstrate that a proportion of cystatin D locates within the cell nucleus at specific transcriptionally active chromatin ...

AIM The aim of the research was to compare the relationship between inflammatory biomarkers and procoagulants with kidney function assessed by using cystatin C, serum creatinine, and eGFR and determine the sensitivity of cystatin C, serum creatinine and eGFR to total cardiovascular morbidity in patients with CKD stages 1-4. METHODS The research included 120 patients older than 18 years with C...

bstract—Cystatin C is distributed in all human tissues and uids with a particular abundance in the cerebrospinal fluid. ystatin C is a strong endogenous inhibitor of lysosomal ysteine proteases, such as cathepsin B, L, H and S, that are nvolved in various biological processes such as degradation f cellular proteins and regulation of enzymes, as well as in athological processes. Pharmacological ...

BACKGROUND AND OBJECTIVES Obesity is a risk factor for incident chronic kidney disease (CKD). Visceral (VAT) and subcutaneous adipose tissue (SAT) may confer differential metabolic risk profiles. The relations of VAT and SAT were analyzed with CKD as estimated by creatinine- and cystatin-based estimating equations. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Participants from the Framingham...
