Fourteen different classes of ribozymes are known that catalyse a range of diverse chemical reactions. We report here a novel potassium-dependent nucleolytic activity present in hepatitis B virus (HBV) RNA. A short RNA region (53 nt) with enzymatic properties released itself from the viral sequence
OBJECTIVE
Studies have shown that potassium channel plays a pivotal role in T cell activation. The expression of potassium channel gene KCTD9 was evidenced being highly upregulated in patients with severe hepatitis B (SHB). To understand this phenomenon further, tissue and cellular expression
UNASSIGNED
Proximal renal tubular dysfunction (PRTD) is an infrequent complication after nucleotide analogue therapy. We evaluated the outcomes of PRTD and nephrotoxicity after nucleotide analogue withdrawal in chronic hepatitis B (CHB).

A longitudinal follow-up study was performed in
Using magnetic nanoparticles (MNPs) as a label in immunoassay (IA) possesses advantages such as high specific surface area, simple modification process. However, the catalytic activity of MNPs is low, which limits their applications in IA. The present study found it interesting that potassium
OBJECTIVE
Refractory ascites (RA) is closely related to a high morbidity and mortality. In this study, we investigated predictors of RA development in patients with hepatitis B virus (HBV)-related cirrhosis who were hospitalized to control ascitic decompensation, and determined predictors for
The epsilon domain of Hepatitis B virus plays a crucial role in encapsidation of viral pregenomic RNA and its partial NMR structure has been determined. However, we recently described a potassium-dependent ribonucleolytic activity associated with this region, so that a 53 nt long RNA containing the
Erythema nodosum migrans (ENM) is believed to represent a variant of chronic erythema nodosum; however, others consider it to be a separate clinical entity. It most commonly affects women in the third to sixth decade of life. Most cases are idiopathic, but some may be associated with streptococcal
Isaacs syndrome or acquired neuromyotonia is a disorder of peripheral nerve hyperexcitability characterized by regular or irregular myokymia, muscle cramps and stiffness, delayed muscle relaxation after contraction, and hyperhidrosis. Herein, we report clinical and electrodiagnostic findings of a
The new automated Enzymun-Test anti-HBc Plus for the detection of antibodies to hepatitis B virus (HBV) core antigen (anti-HBc) after pretreatment with reducing agents dithiothreitol (25 degrees C; + DTT) or potassium bisulfite (37 degrees C; + MBS) was evaluated by testing 571 serum and plasma
Hepatitis B surface antigen (HBsAg) is known to adsorb to aluminum hydroxide adjuvant (AH) by ligand exchange between its accessible phosphate groups and surface hydroxyl groups of the adjuvant. To study the effect of the binding strength, five vaccines were prepared with AH or four samples of AH
We explored the expression of a newly identified potassium channel tetramerisation domain containing 9 (KCTD9) protein in 113 blood and 81 liver samples, from patients with mild chronic hepatitis B (CHB) or HBV-induced acute-on-chronic liver failure (HBV-ACLF). KCTD9 was highly expressed in
Chronic hepatitis B virus (HBV) infection remains a major health problem worldwide. The main clinical limitation of a current antiviral drug for HBV, lamivudine, is the emergence of drug-resistant viral strains upon prolonged therapy. A group of 5-, 6-, or 5,6-substituted acyclic pyrimidine
Hepatitis B virus (HBV) infection is a major worldwide health problem which can cause acute and chronic hepatitis and can significantly increase the risk of liver cirrhosis and primary hepatocellular carcinoma (HCC). Nowadays, clinical therapies of HBV infection still mainly rely on nucleotide
BACKGROUND
In this paper, we explore nephrogenic hypophosphatemic osteomalacia associated with low-dose adefovir dipivoxil (ADV) therapy.
METHODS
Five patients who were treated with ADV for >2 years were included in this study. The metabolic index of phosphate and calcium, renal tubular function,
