We analyze the consistency strength of regularity on the basis of Feferman’s operational set theory OST. Our main result shows that regularity over OST for operations corresponds to regularity with respect to set-theoretic functions in frameworks like Kripke-Platek set theory. As a consequence, we obtain that OST plus the operational axiom (Inac) is consistency-equivalent to Kripke-Platek set t...
PURPOSE To evaluate the male osteoporosis risk estimation score (MORES) and the osteoporosis self-assessment screening tool (OST) score as a means of screening for osteoporosis in men. METHODS Records of 113 Indonesian men aged 50 to 91 (mean, 71) years who underwent evaluation of bone mineral density (T-score) using Dual-energy X-ray absorptiometry were retrospectively reviewed. The MORES wa...
The preventive effect of the herbal formulation OST-6 (Osteocare) on the progress of bone loss induced by ovariectomy and concurrent calcium deficiency was studied in rats. Ovariectomy (OVX) and calcium deficiency (CD) resulted in bone loss as evident from decreased femoral weight and density. Treatment with OST-6 at a dose of 250 mg/kg body wt twice a day orally for a period of 16 weeks signif...
One-session treatment (OST), a variant of cognitive-behavioral therapy, combines graduated in vivo exposure, participant modeling, reinforcement, psychoeducation, cognitive challenges, and skills training in an intensive treatment model. Treatment is maximized to one 3-hour session. In this paper, we review the application of OST for specific phobia in youth and highlight practical matters rela...
Background Hepatitis C virus (HCV) direct-acting antiviral therapy is effective among people receiving opioid substitution therapy (OST), but studies are limited by small numbers of nongenotype 1 (GT1) patients. The aim of this study was to evaluate the treatment completion, adherence, SVR12, and safety of sofosbuvir-based therapies in HCV patients receiving and not receiving OST. Methods Ten...
As cells integrate molecular signals from their environment, cell surface receptors require modified proteoglycans for the robust activation of signaling pathways. Heparan sulfate proteoglycans (HSPGs) have long unbranched chains of repetitive disaccharide units that can be sulfated at specific positions by heparan sulfate O-sulfotransferase (OST) families. Here, we show that two members of the...
The journey of many viruses to infect cells begins when the virus first binds to cell surface heparan sulfate (HS). The initial step of cell attachment or binding during herpes simplex virus type-1 (HSV-1) entry is mediated by envelope glycoprotein B (gB) and C (gC). The binding is followed by fusion between virus envelope and cell membrane during which HSV-1 glycoprotein D (gD) interacts with ...
Novel amphiphilic chitosan derivatives (N-caprinoyl-N-trimethyl chitosan [CA-TMC]) were synthesized by grafting the hydrophobic moiety caprinoyl (CA) and hydrophilic moiety trimethyl chitosan to prepare carriers with good compatibility for poorly soluble drugs. Based on self-assembly, CA-TMC can form micelles with sizes ranging from 136 nm to 212 nm. The critical aggregation concentration incre...
