This rapid and efficient method to prepare highly purified recombinant adeno-associated viruses (rAAVs) is based on binding of negatively charged rAAV capsids to an anion-exchange resin that is pH dependent.

Plasmid DNA is prepared from the recombinant shuttle vector pLD53.SCAB/A-B created by cloning of the A and B homology arms for two-step bacterial artificial chromosome (BAC) engineering. To confirm that the A-box and B-box arms have been successfully incorporated into pLD53.SCAB, the pattern of enzyme digestion of the modified plasmid is compared with that of the unmodified pLD53.SCAB. Once the shuttle vector is shown to carry the proper sequences, it is ready for transfer into the BAC host.

The 700-bp A homology arm (A-box) and the 700-bp B homology arm (B-box) are amplified by polymerase chain reaction (PCR) using purified bacterial artificial chromosome (BAC) DNA as template for two-step BAC engineering. The resulting A-box PCR product contains an AscI site at its 5' end (the 5' primer incorporates an AscI site, and the 3' primer does not incorporate any restriction sites). The B-box PCR product contains an XmaI site at its 3' end (the 5' primer does not incorporate any restriction sites, and the 3' primer incorporates an XmaI site). The amplification products are then digested with the appropriate restriction endonucleases to render them suitable for cloning into the shuttle vector.

In two-step bacterial artificial chromosome (BAC) engineering, a single plasmid is introduced into the BAC-carrying cell lines. The shuttle vector pLD53.SCAB (or pLD53.SCAEB) carries the recA gene and the R6K origin, which requires the protein to replicate. PIR2 cells, expressing , are typically used for the amplification of the vector and maintain about 15 copies/cell of the donor vector, which is relatively stable in this host.

The importance of transition from pediatric to adult health care for youth with special health care needs has gained increasing attention over the past decade, but fewer than half of this population received needed transition preparation in 2005–2006.

This study reports on transition findings from the 2009–2010 National Survey of Children with Special Health Care Needs and finds no discernible improvements since 2005–2006. New clinical recommendations and care processes should help to accelerate transition improvements in the future. (Read the full article)

Available bowel preparation solutions for colonoscopy continue to represent a challenge for children and their families due to poor taste, high volume, and dietary restrictions with subsequent poor compliance and need to place nasogastric tube for administration.

Low-volume polyethylene glycol (PEG) preparations and sodium picosulphate plus magnesium oxide and citric acid (NaPico+MgCit) are noninferior to PEG 4000 with simethicon for bowel preparation before colonoscopy in children. Given its higher tolerability and acceptability profile, NaPico+MgCit should be preferred in children. (Read the full article)

About 1 in 6 Americans gets sick every year from foodborne illnesses. Under the Food Safety Modernization Act (FSMA), FDA and the USDA work closely to trace the cause and origin of these illnesses. Traceability is key so the origin is quickly detected, and a recall enacted, preventing others from becoming ill. Preparation and planning are necessary for produce growers and businesses in the supply chain to successfully navigate a product recall. The Delaware Department of Agriculture’s Produce Safety Program will present the United Fresh Recall Ready Workshop on January 22, 2020 at Dover Downs from 8 a.m. to 5 p.m.

The Delaware Division of Public Health (DPH) is actively taking steps to prepare for community spread of the coronavirus disease known as COVID-19, as well as providing information to Delawareans about the actions they can take now to make preparations.

Approved project 50333-001 in Bangladesh.

Commonly used model teeth are so far uniform in color and hardness. There is no discrimination between enamel and dentin part of a tooth. This condition makes it difficult to train a preparation technique, which is adapted to real tooth substance. The aim of this study was to design and establish a 3D printed tooth with different layers for enamel and dentin for education in crown preparation. A printable tooth with different layers for enamel and dentin was designed, and all 38 fourth-year dental students in the first clinical course in prosthodontics and 30 experienced dentists were trained during a voluntary hands-on course in 2019. Prior to the study, the students had used standard model teeth and real-teeth models in their preclinical education. They had experience in caries removal and preparation on real patients. The perceived benefits of the 3D printed tooth were evaluated by a questionnaire. All individuals in both groups completed the questionnaire, for a 100% response rate. The results showed that the printed tooth was given an overall mean grade of 2.3 (students) and 2.0 (experts) on a scale from 1=excellent to 5=poor. The difference in hardness between the dentin and enamel layer was given a mean of 2.4 (students and experts) and the difference in color a 1.7 (students) and 1.8 (experts). The tooth model with the prepared tooth illustrating an ideal preparation was graded 1.6 (students and experts). In this study, the students had the opportunity to learn a correct crown preparation on a printed tooth with different material properties for enamel and dentin. The learning effect with this tooth model was rated as good on the questionnaire by both students and expert dentists.

⁶⁸Ga-labeled urea-based inhibitors of the prostate-specific membrane antigen (PSMA), such as ⁶⁸Ga-PSMA-11, are promising small molecules for targeting prostate cancer (PCa). Although this radiopharmaceutical was produced mostly by means of manual synthesis and automated synthesis modules, a sterile cold kit was recently introduced. The aim of our study was to evaluate the image quality of ⁶⁸Ga-PSMA-11 PET/CT (PSMA-PET) in a population of PCa patients after the injection of comparable activities of ⁶⁸Ga-PSMA-11 obtained with the 2 different synthetic procedures. A secondary aim was to identify secondary factors that may have an impact on image quality and, thus, final interpretation. Methods: Two different groups of 100 consecutive PCa patients who underwent PSMA-PET were included in the study. The first group of patients was imaged with ⁶⁸Ga-PSMA-11 obtained using synthesis modules, whereas the second group’s tracer activity was synthesized using a sterile cold kit. All PET images were independently reviewed by 2 nuclear medicine diagnosticians with at least 2 y of experience in PSMA-based imaging and unaware of the patients’ clinical history. The 2 reviewers independently rated the quality of each PSMA-PET scan using a 3-point Likert-type scale. In cases of discordance, the operators together reviewed the images and reached a consensus. Performance was evaluated on the basis of the expected biodistribution, lesion detection rate, and physiologic background uptake. Results: Overall, 104 of 200 (52%) PSMA-PET scans were positive for PCa-related findings. No significant differences in image quality between cold kits and synthesis modules were found (P = 0.13), although a higher proportion of images was rated as excellent by the observers for kits than for modules (45% vs. 34%). Furthermore, after image quality had been dichotomized as excellent or not excellent, multivariate regression analysis found several factors to be significantly associated with a not-excellent quality: an increase in patient age (+5 y: odds ratio [OR], 1.40; 95% confidence interval [CI], 1.12–1.75), an increase in patient weight (+5 kg: OR, 1.89; 95% CI, 1.53–2.32), an increase in ⁶⁸Ga-PSMA-11 uptake time (+10 min: OR, 1.45; 95% CI, 1.08–1.96), and a decrease in injected activity (–10 MBq: OR, 1.28; 95% CI, 1.07–1.52). Conclusion: No significant differences were identified between the 2 groups of patients undergoing PSMA-PET; therefore, we were not able to ascertain any significant influences of tracer production methodology on final scan quality. However, increased patient age, increased patient weight, decreased injected activity, and increased ⁶⁸Ga-PSMA-11 uptake time were significantly associated with an overall poorer image quality.
