Sandosh Padmanabhan, Bina Joe
Compelling evidence for the inherited nature of essential hypertension has led to extensive research in rats and humans. Rats have served as the primary model for research on the genetics of hypertension resulting in identification of genomic regions that are causally associated with hypertension. In more recent times, genome-wide studies in humans have also begun to improve our understanding of the inheritance of polygenic forms of hypertension. Based on the chronological progression of research into the genetics of hypertension as the "structural backbone," this review catalogs and discusses the rat and human genetic elements mapped and implicated in blood pressure regulation...

It is the declared objective of the Falsified Medicines Directive 2011/62/EU to further improve the protection of patients from falsified pharmaceuticals. Therefore, it stipulates measures based on which falsified medicines in the supply chain can be more easily identified. This is the European legislature's reaction to an increase in falsified medicines. The EU Falsified Medicines Directive aims to create a uniform, standardized solution for protection from falsified drugs. From 9 February 2019 onward (according to the EU Regulation No...

Crime on the internet has grown accordingly to the increased use of the internet in everyday life. This includes illegal trading of pharmaceuticals via the internet. Trading in pharmaceuticals as "special commodities" underlies certain legal regulations in Germany, as in most other countries worldwide.Mail order trade (colloquially also known as internet trade) in pharmaceuticals requires approval of the competent regulatory authority. However, numerous illegal internet vendors of medicines present their websites to customers, purporting to be legal pharmacies and trading good and genuine medicines...

Radionuclide absorbed-dose dosimetry is an active area of development and has the potential to positively impact molecular radiotherapies. At present, many of the operations required to perform dosimetry calculations are unstandardized and unestablished. While the current methodology allows reasonable dosimetry estimates to be derived and published, it can be difficult to understand, and reproduce, each others' work. To help alleviate this we have identified the collection of biodistribution information as a key step in all internal dosimetry calculations, and present a template that can be used to standardize its documentation and reporting...

BACKGROUND: Observational clinical studies play a pivotal role in advancing medical knowledge and patient healthcare. To lessen the prohibitive costs of conducting these studies and support evidence-based medicine, results emanating from these studies need to be shared and compared to one another. Current approaches for clinical study management have limitations that prohibit the effective sharing of clinical research data. METHODS: The objective of this paper is to present a proposal for a clinical study architecture to not only facilitate the communication of clinical study data but also its context so that the data that is being communicated can be unambiguously understood at the receiving end...

BACKGROUND AND IMPORTANCE: In contrast to cranial interventions, neuronavigation in spinal surgery is used in few applications, not tapping into its full technological potential. We have developed a method to preoperatively create virtual resection planes and volumes for spinal osteotomies and export 3-D operation plans to a navigation system controlling intraoperative visualization using a surgical microscope's head-up display. The method was developed using a Sawbone ® model of the lumbar spine, demonstrating feasibility with high precision...

Computer simulation is a highly advantageous method for understanding and improving healthcare operations with a wide variety of possible applications. Most computer-simulation studies in emergency medicine have sought to improve allocation of resources to meet demand, or to assess the impact of hospital and other system policies on emergency department (ED) throughput. These models have enabled essential discoveries that can be used to improve the general structure and functioning of EDs. Theoretically, computer simulation could also be used to examine the impact of adding or modifying specific provider tasks...

The author summarizes briefly the history of hand allograft transplantation, the basics of the operative technics, and the medicinal treatment of the immunosuppression. He establishes that this operation requires complicated team-work: many specialists must be united in the interest of the successful final outcome. The biggest problem is not the technical challenge of the complicated operation, but the ineffectiveness of immunosuppression, its complications; even though significant development has happened in this field and experimental results are also encouraging...

Rose hip is the fruit of the rose plant, which is widely used in food, cosmetics and as a traditional medicine. Therefore, rose hip is considered safe and has a sufficient history of consumption as food. However, few studies have reported on the safety of rose hip extracts in toxicological analyses. Thus, to evaluate the safety of rosehip polyphenol MJ (RHPMJ), an aqueous ethanol extract standardized with the trans-tiliroside content, we performed genotoxicity and 90-day repeated oral dose toxicity studies in compliance with the Organisation for Economic Co-operation and Development-Good Laboratory Practice...

This retrospective study utilizes 3D imaging and mammometrics to compare implant-based breast reconstruction with and without the use of ADM. Previous studies have suggested improved aesthetic outcomes with the use of ADM, but none have been able to quantify this difference. Images were obtained at early and late time points following the expander-implant exchange procedure. Measurements included the point of maximum projection, the superior, inferior, medial and lateral volumetric distribution, and the distance from the point of maximum projection to the inframammary fold along the breast meridian...

PURPOSE: To introduce a temperature sensor implant (TSI) that mimics an active implantable medical device (AIMD) for animal testing of MRI heating. Computer simulations and phantom experiments poorly represent potential temperature increases. Animal experiments could be a better model, but heating experiments conducted immediately after the surgery suffer from alterations of the thermoregulatory and tissue properties during acute testing conditions. Therefore, the aim of this study was to introduce a temperature sensor implant that mimics an AIMD and capable of measuring the electrode temperature after implantation of the device without any further intervention at any time after the surgery in an animal model...
