Applications of Liquid Chromatography-Tandem Mass Spectrometry in Natural Products Research: Tropane Alkaloids as a Case Study.

Although many drugs utilized today are synthetic in origin, natural products still provide a rich source of novel chemical diversity and bioactivity, and can yield promising leads for resistant or emerging diseases. The challenge, however, is twofold: not only must researchers find natural products and elucidate their structures, but they must also identify what is worth isolating and assaying (and what is already known - a process known as dereplication). With the advent of modern analytical instrumentation, the pace of natural product discovery and dereplication has accelerated.

Validation of a High Flow Rate Puff Topography System Designed for Measurement of Sub-Ohm, Third Generation Electronic Nicotine Delivery Systems.

There are few known puff topography devices designed solely for gathering electronic cigarette puff topography information, and none made for high-powered sub-ohm devices. Ten replicate Bernoulli flow cells were designed and 3D printed. The relationship between square root of pressure difference and flow rate was determined across 0−70 L/min.

Osteopathic Physician Mortality in the Influenza Pandemic of 1918-1920.

The influenza outbreak that occurred during 1918-1920 was a defining moment in the history of the world and osteopathic medicine. Despite the tremendous loss of human life, osteopathic physicians also observed greater success in the treatment of patients with the disease, in contrast with their allopathic counterparts. Osteopathic physicians also succumbed to the deadly influenza effects while treating patients.

Medication adherence in patients with mental illness and recent homelessness: contributing factors and perceptions on mobile technology use.

Objectives: The primary objective was to determine medication-taking behaviours and factors influencing adherence in patients with mental illness and recent homelessness. Secondary objectives were to explore patients' perceptions on mobile technology use to support adherence.

Methods: A constructivist approach and qualitative description method was used.

Challenges, Opportunities, and Motivators for Developing and Applying Food Literacy in a University Setting: A Qualitative Study.

Background: Evolving norms and complex food environments may require new skill sets and mind-sets to maintain a healthy diet. Food literacy acknowledges the influence of external factors in shaping a person's development and application of the knowledge, skills, and behaviors required for healthy eating. Food literacy among college students is not well understood; however, higher education presents a unique opportunity for promoting food literacy.

Text messaging interventions for individuals with mental health disorders including substance use: A systematic review.

We completed a systematic review of the literature to characterize the impact of text messaging interventions on medication adherence or mental health related outcomes in people with mental health disorders including substance use. Four electronic databases were searched from January 1999 to October 2015. Seven studies met our inclusion criteria: three studies evaluated text messaging in patients with schizophrenia or schizoaffective disorder diagnosis, two studies evaluated text messaging in patients with chronic alcohol dependence, and two studies reviewed text messaging in patients with mood disorders.

An International Survey to Understand Infection Control Practices for Spinal Cord Stimulation.

Objectives: Surgical site infections (SSIs) are associated with significant healthcare costs and morbidity. Limited research exists specific to the prevention of spinal cord stimulation (SCS) SSIs. The objectives of this international survey were to examine current infection control practices for SCS trials and implants and to compare reported responses with evidence-based recommendations.

The interaction between the composition of preinjected fluids and duration of radiofrequency on lesion size.

Background: Clinical recommendations for the duration of radiofrequency (RF) delivery have been based on no-fluid design, which may not be representative of clinical practice where fluid preinjection occurs. The purpose of this study was to examine the interaction between the preinjection of fluids of differing compositions and duration of RF on lesion size. The variability of lesion development under different preinjection conditions was also examined across the RF lesion duration.

Stemming the tide of drug-resistant Neisseria gonorrhoeae: the need for an individualized approach to treatment.

Drug-resistant Neisseria gonorrhoeae poses a significant public health challenge. In recent years, gonococci resistant to first- and second-line antibiotics have spread worldwide and new strains have developed that are increasingly resistant to third-generation cephalosporins, which are currently our last line of available treatments. Given the timeline required to develop new drugs or an effective vaccine for N.

Pharmacists and harm reduction: A review of current practices and attitudes.

Background: Injection drug use and other high-risk behaviours are the cause of significant morbidity and mortality and thus have been the focus of many health promotion strategies. Community pharmacists are considered underutilized health providers and are often thought to be more accessible than other health professionals. The purpose of this review is to provide an overview of community pharmacists' practices as well as pharmacists' attitudes and identified barriers toward providing harm reduction services.

Effect of localizing fruit and vegetable consumption on greenhouse gas emissions and nutrition, Santa Barbara County.

The US agrifood system is very productive, but highly centralized and resource intensive with very weak links between production and consumption. This contributes to high levels of malnutrition and greenhouse gas emissions (GHGE). A popular approach to improvement is localization-reducing direct transport (farm to retail distance, or "food miles").
