Availability of the HPV Vaccine in Regional Pharmacies and Provider Perceptions Regarding HPV Vaccination in the Pharmacy Setting.

There is increasing support for HPV vaccination in the pharmacy setting, but the availability of the HPV vaccine is not well known. Additionally, little is known about perceptions of medical providers regarding referring patients to community pharmacies for HPV vaccination. The purpose of this study was to determine HPV vaccine availability in community pharmacies and to understand, among family medicine and obstetrics-gynecology providers, the willingness of and perceived barriers to referring patients for HPV vaccination in a pharmacy setting. HPV vaccine availability data were collected from pharmacies in a southern region of the United States. Family medicine and obstetrics-gynecology providers were surveyed regarding vaccine referral practices and perceived barriers to HPV vaccination in a community pharmacy. Results indicated the HPV vaccine was available in most pharmacies. Providers were willing to refer patients to a community pharmacy for HPV vaccination, despite this not being a common practice, likely due to numerous barriers reported. Pharmacist-administered HPV vaccination continues to be a commonly reported strategy for increasing HPV vaccination coverage. However, coordinated efforts to increase collaboration among vaccinators in different settings and to overcome systematic and legislative barriers to increasing HPV vaccination rates are still needed.

Studies on lysozyme modifications induced by substituted p-benzoquinones.

Protein misfolding can facilitate a protein damaging process and makes it susceptible to a series of events such as unfolding, adduct formation, oligomerization, or aggregation. Loss of a protein's native structure may result in its biological malfunction and/or cellular toxicity that could cause associated diseases. Several factors were identified for causing structural changes of a protein, however quinone-induced protein modifications received very little attention whether for amyloidal or non-amyloidal proteins. In this paper, we report our investigation on lysozyme modifications upon treatment with selected benzoquinones (BQs), utilizing fluorescence spectroscopy including anisotropy determination, UV-Vis spectroscopy, and SDS-PAGE. Lysozyme was reacted with substituted BQs in order to examine substituent effects on protein modifications. In addition, we evaluated lysozyme modifications induced by 1,4-benzoquinone in concentration-, pH-, temperature-, and time-dependent studies. Our study shows that all BQs can readily modify lysozyme in a complex manner through adduct formation, oligomerization, polymeric aggregation, and/or fibrilization. Electrochemical properties of selected BQs were monitored using cyclic voltammetry in phosphate buffered aqueous solution, and it was found that quinone reduction potentials correlate well with their reactivity trend toward lysozyme.

Adeno-associated virus serotype rh10 is a useful gene transfer vector for sensory nerves that innervate bone in immunodeficient mice.

Adeno-associated virus (AAV) is frequently used to manipulate gene expression in the sensory nervous system for the study of pain mechanisms. Although some serotypes of AAV are known to have nerve tropism, whether AAV can distribute to sensory nerves that innervate the bone or skeletal tissue has not been shown. This information is crucial, since bone pain, including cancer-induced bone pain, is an area of high importance in pain biology. In this study, we found that AAVrh10 transduces neurons in the spinal cord and dorsal root ganglia of immunodeficient mice with higher efficacy than AAV2, 5, 6, 8, and 9 when injected intrathecally. Additionally, AAVrh10 has tropism towards sensory neurons in skeletal tissue, such as bone marrow and periosteum, while it occasionally reaches the sensory nerve fibers in the mouse footpad. Moreover, AAVrh10 has higher tropic affinity to large myelinated and small peptidergic sensory neurons that innervate bone, compared to small non-peptidergic sensory neurons that rarely innervate bone. Taken together, these results suggest that AAVrh10 is a useful gene delivery vector to target the sensory nerves innervating bone. This finding may lead to a greater understanding of the molecular mechanisms of chronic bone pain and cancer-induced bone pain.
