INTRODUCTION The use of bone grafts in orthopedic, maxillofacial and dental surgery has been growing. Nevertheless, both fresh autografts and frozen allografts have limitations, and therefore, alternative synthetic or natural biomaterials, such as processed and lyophilized bovine bone graft have been developed. OBJECTIVE To evaluate in vitro and in vivo biocompatibility of lyophilized bovine ...
Anti-drug antibodies in hemophilia patients substantially complicate treatment. Their elimination through immune tolerance induction (ITI) protocols poses enormous costs, and ITI is often ineffective for factor IX (FIX) inhibitors. Moreover, there is no prophylactic ITI protocol to prevent anti-drug antibody (ADA) formation. Using general immune suppression is problematic. To address this urgen...
A previously developed Russell's viper venom toxoid in Myanmar is in a liquid form that shows reversion in the form of a reduced number of formaldehyde linkages and toxicity during storage at 37 degrees C and at room temperature. In order to have a safe, potent and stable toxoid, a lyophilized form was prepared in the present study from the liquid toxoid through the use of a freeze dryer. Both ...
The irreversible hydrolysis of 1-chlorobutane to 1-butanol and HCl by lyophilized cells of Rhodococcus erythropolis NCIMB 13064, using a solid–gas biofilter, is described as a model reaction. 1-Chlorobutane is hydrolyzed by the haloalkane dehalogenase from R. erythropolis. A critical water thermodynamic activity (aw) of 0.4 is necessary for the enzyme to become active and optimal dehalogenase a...
Coxiella burnetii, the causative pathogen for Q fever, is an obligate intracellular bacterium and designated as a biosafety level 3 agent. Detection and quantification of the bacteria with conventional culturing methods is time-consuming and poses significant health risks. Polymerase chain reaction (PCR)-based assays have been developed for detecting C. burnetii and could provide rapid diagnosi...
Amide hydrogen/deuterium exchange (ssHDX-MS) and side-chain photolytic labeling (ssPL-MS) followed by mass spectrometric analysis can be valuable for characterizing lyophilized formulations of protein therapeutics. Labeling followed by suitable proteolytic digestion allows the protein structure and interactions to be mapped with peptide-level resolution. Since the protein structural elements ar...
background: melanoma causes the greatest morbidity and mortality of all skin cancers. mucosal melanoma is a rare but highly aggressive neoplasm. according to previous studies the prevalence of kit mutations in acrallentiginous and mucosal melanomas is relatively low (less than 15–20%), but it can have profound therapeutic implications for localized high risk or metastatic diseases. our goal was...
OBJECTIVE To assess the pharmacokinetics and safety of liquid palivizumab compared with lyophilized palivizumab. METHODS This phase 2, randomized, double-blind crossover study included premature infants aged ≤6 months born ≤35 weeks gestational age. Patients were randomized in a 1:1 ratio to receive a single 15 mg/kg intramuscular dose of liquid (sequence A group) or lyophilized (sequence B g...
The potential of bioneedles to deliver influenza vaccines was investigated. Four influenza vaccine formulations were screened to determine the optimal formulation for use with bioneedles. The stability of the formulations after freeze-drying was checked to predict the stability of the influenza vaccines in the bioneedles. Subunit, split, virosomal and whole inactivated influenza (WIV) vaccine w...
Background. Bone grafts are used in the treatment of nonunion of fractures, bone tumors and in arthroplasty. Tissues preserved by lyophilization or deep freezing are used as implants nowadays. Lyophilized grafts are utilized in the therapy of birth defects and bone benign tumors, while deep-frozen ones are applied in orthopedics. The aim of the study was to compare the pyrolytic pattern, as an ...
