RESEARCH REVEALS CHEMICAL PFO(A) IS AIRBORNE

ALLON SHOWS STATISTICALLY SIGNIFICANT IMPROVEMENT IN SCHIZOPHRENIA IMAGING STUDY

Allon Therapeutics Inc. has released results from an imaging study of schizophrenia patients showing that 12 weeks of treatment with its lead neuroprotective drug candidate davunetide resulted in a significant increase in levels of a biomarker that is an indicator of brain cell health. Increased levels of N-acetyl aspartate (NAA) were measured in the brains of the schizophrenia patients treated with davunetide using magnetic resonance spectroscopy (MRS). The scientific literature shows that NAA is an informative biomarker because

decreased levels of NAA occur in schizophrenia and in numerous other neurodegenerative conditions such as brain injury, stroke, and Alzheimer’s disease. The study specifically measured NAA from the dorsolateral prefrontal cortex, an area of the brain known to be affected in schizophrenia patients. These results were obtained with davunetide doses already known to be active in human clinical trials and appear to correlate with the davunetide-dependent behavioural outcomes in these same patients.

the environment than previously thought. PFO(A) is indefinitely persistent in the environment and has been detected in industrial waste, stain resistant carpets and clothing, carpet cleaning liquids, house dust, microwave popcorn

bags, water, food and nonstick cookware. Environment Canada, Health Canada and the Environmental Protection Agency (EPA) in the US have been investigating PFO(A) because it is persistent in the environment and has potentially adverse effects. It is a toxicant and carcinogen in animals. In people, it is detected in the blood of general populations in the low parts per billion range where studies have associated it with infertility, higher cholesterol, and thyroid disease. In highly exposed animals, some studies have associated PFO(A) exposure with birth defects, increased cancer rates, and changes to the immune system and liver. Previously, the scientific community believed that PFO(A) generally stayed in the areas where the chemical was created, in urban centres, or traveled in water where it was subject

to slow movement due to ocean currents. Dr Ellis’ research, however, shows that PFO(A) is actually being emitted out of the lakes and oceans and into the air, thereby having the ability to travel much faster and much more freely. The mathematical models developed as a part of this work allowed Dr Ellis to test his theories and the previously existing theories against real world observations. “In reality, we have discovered that the action of wave breaking liberates the chemical into air, making the dissemination equivalent to something like a smoke stack,” Dr Ellis says. Dr Ellis’s research, which was undertaken in the labs at Trent University, is being published in three major papers in Environmental Toxicology and Chemistry, a leading international, peer-reviewed journal, in April/May 2010.

ONCOGENEX DRUG CANDIDATE BOLSTERED BY PEER-REVIEWED RESEARCH

OncoGenex Pharmaceuticals Inc. announces that two peer-reviewed manuscripts have been published that provide additional insight into the function of Heat Shock Protein 27 (Hsp27) and its role in promoting tumour resistance to cancer treatment. OncoGenex’s drug candidate OGX-427 is designed to reduce levels of Hsp27, a protein that is over-produced in response to many cancer treatments including hormone ablation therapy, chemotherapy and radiation therapy. Two



recently published peer-reviewed manuscripts describe the signalling pathways by which Hsp27 mediates tumour cell survival, providing additional rationale for inhibiting Hsp27 as a therapeutic approach for cancer treatment. In a manuscript published in Cancer Research, researchers define the links between Hsp27 phosphorylation and Insulin-like growth factor-1 (IGF-1) signalling in prostate cancer. IGF-1 is a well documented stimulator of cell growth and proliferation, and a potent inhibitor of programmed cell death. In a separate manuscript published in Oncogene, researchers identify a mechanism by which changes in Hsp27 expression serve as an upstream regulator of eIF4E, a key regulator for protein synthesis. By chaperoning eIF4E, Hsp27 protects the protein synthesis initiation process to enhance cell survival during cell stress induced by castration or chemotherapy.

NANOSTRING LAUNCHES miRNA EXPRESSION ASSAYS NanoString Technologies has unveiled a new product for microRNA analysis that uses multiplex digital barcode technology to profile the human miRNA transcriptome in a single tube. The new human miRNA expression assay kit is based on the same digital barcoding technology that forms the foundation of NanoString’s gene expression CodeSets and, as such, can be run on the company’s nCounter prep station and digital analyzer. The company’s gene expression codesets are pairs of approximately 50-base probes that hybridize and are used to detect and count mRNA transcripts. The nCounter digital analyzer collects data from multiple probe complexes, each one immobilized in colour-coded cartridges. According to NanoString, the technology can detect and count hundreds of gene transcripts simultaneously with a sensitivity of less than one copy per cell. As such, the company has been positioning the nCounter gene expression assays as bridging a gap between qPCR and microarrays. NanoString is also touting the simplicity of the miRNA expression assays because they are only slightly modified versions of the already proven mRNA assay kits. In addition, NanoString disclosed that researchers from the University Health Network in Toronto, the Mayo Clinic, Ohio State University, and Uni-

versity of Miami School of Medicine are among the early-access customers who have been using the product ahead of its commercial launch. The assay kits enable researchers to perform highly multiplexed, direct digital detection and counting of miRNAs at single-base resolution without the need for PCR amplification. Further, researchers can profile more than 700 human and human-viral miRNAs with specificity and sensitivity comparable to qPCR at a fraction of the cost, the company said. NanoString unveiled the new kits at the American Association for Cancer Research annual meeting in Washington, DC.

STEM CELL THERAPEUTICS ANNOUNCES PUBLICATION OF PHASE IIA STROKE DATA Stem Cell Therapeutics Corp. announces the paper entitled “The BetahCG + Erythropoietin in Acute Stroke (BETAS) Study” has been accepted to run in the journal Stroke. This paper was authored by Dr. Steven C. Cramer, from the University of California, Irvine; Dr. David Brown at Hoag Memorial Hospital Presbyterian, New Port Beach; Dr. Michael D.

INTERNATIONALLY EDUCATED MEDICAL LABORATORY TECHNOLOGISTS BRIDGING PROGRAMS GOOD FOR CANADA self-identified IEMLTs through immigration annually. The practice of medical laboratory science varies across the globe, and it is a requirement that all practitioners in Canada meet the rigorous entry to practice requirement, putting patient safety first at all times. A system that allows for additional training or practice in the Canadian context, that is accessible, affordable and reliable is imperative.”

A recent report produced by the Canadian Society for Medical Laboratory Science (CSMLS) offers the first clear evidence that sustained government funding of bridging programs for internationally educated medical laboratory technologists (IEMLTs) is good fiscal policy. The report, “Bridging Programs for Internationally Educated Medical Laboratory Technologists: A Business Case,” was funded by the Government of Canada’s Foreign Credential Recognition Program. Researched by the Centre for Spatial Economics and authored by Dr. Moira Grant, CSMLS director of Research, the report concluded that bridging programs shorten the time for IEMLTs to become certified in Canada, decrease their financial hardships and expedite their integration into the Canadian laboratory workplace. As a result, IEMLTs contribute to the Canadian economy much sooner with the support of a bridging program. Christine Nielsen, executive director, CSMLS, states that, “there is a growing shortage of medical laboratory technologists in Canada, and we consistently receive about 600

CSMLS is the national certifying body for MLTs and medical laboratory assistants and the national professional society for Canada’s medical laboratory professionals. With the exception of Quebec, MLTs across Canada require CSMLS certification as a condition of licensure. Tania Toffner, director of certification and prior learning assessment says, “CSMLS conducts a prior learning as-

Sherbrooke’s University Hospital (Centre hospitalier universitaire de Sherbrooke - CHUS) recently modernized its biochemistry and hematology laboratories. “This laboratory automation project, representing investments of $3.5M in equipment and renovation, was accomplished in partnership with Roche Diagnostics and Sysmex. It allows the CHUS to improve its performance and to shorten response and results turnaround time through the standardization of all testing procedures. Patients will get the most benefits from this modernization, as our services are now faster and safer”, said the CHUS general manager, Patricia Gauthier. Roche Diagnostics was entrusted with the responsibility for laboratory set-up sessment (PLA) to evaluate the credentials and work experience of IEMLTs to determine if they are eligible to write the CSMLS national certification examination. Over 90 per cent of the more than 300 IEMLTs who apply annually to the PLA process are not equivalent to the Canadian standards.” CSMLS provides IEMLTs with a learning plan and courses to help them address the knowledge gaps

and renovations, as well as new technology acquisition. Roche made a commitment to provide the equipment offering the best available performance and throughput in a context of qualified labour shortage. The new automated equipment integrates all analysis procedures and steps, and ensures their uninterrupted flow. Samples go from centrifuging (separation of solid particles in suspension in a liquid), to aliquoting (division of a sample into several portions), to analysis and results compiling without ever being touched by an operator. The robotized system manages the various tests to be run for a given patient out of a single test tube, which reduces significantly the amount of blood that is required. in order to write the exam. Since 2000, approximately 750 IEMLTs have been certified by CSMLS. The report concluded that supporting IEMLTs through a government subsidized bridging program addresses both health care resource challenges and the need for equitable treatment of newcomer professionals to Canada with expectation of employment in their profession.

THE IMPORTANCE OF PRE-CLEANED

CHROMATOGRAPHY

VIALS

MASS SPECTROMETRY is a powerful analytical technique commonly coupled with differing chromatography methods for sample separation. Since it is increasingly being adapted for more diverse applications, contamination issues affecting sensitivity and reproducibility must always be considered. Advances in GC practice, such as employing on-column injection, and newer techniques employing finely packed HPLC columns, require the elimination of as much particulate matter as possible from the sample stream. The quality of sample vials used can potentially compromise final analysis and this provides a compelling case for the use of chromatography vials which are cleaned to remove trace level contaminants and tested as standard. This article investigates the effectiveness of the industry’s first pre-cleaned chromatography vials, the new National Scientific Mass Spec Certified Vials from Thermo Fisher Scientific for highly sensitive applications where chromatography is coupled with mass spectrometry.

It is also used in the environmental industry for monitoring polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), water quality, and food contamination; and in the geological industry for investigating oil composition. In addition, mass spectrometry is proving ever more versatile in the clinical setting for neonatal screening, hemoglobin analysis, drug and other analyte testing, proteomics, and biomarker analysis. Chromatographers have always depended on high temperature glass forming

Detection of compounds can be accomplished with very minute quantities in mass spectrometry. This means that compounds can be identified at very low concentrations, down to the femtogram level, in chemically complex mixtures. Advances in sample separation techniques and materials have greatly improved the reliability, sensitivity, precision and accuracy of mass spectrometry, expanding its versatility and application base. Mass spectrometry, therefore, now provides valuable information in biotechnology, for example, on the analysis of proteins, peptides and oligonucleotides; and in the phar-

cent advances in instrument construction and separation techniques, however, have resulted in cases where high temperature glass forming procedures cannot guarantee the production of a vial with no detectable background.

The presence of inorganic sub micron particles in all glass vials as a byproduct of the manufacturing process is a phenomenon that has not been extensively studied. Gas chromatographers depend on injection port liners

to act as traps for particulates while the HPLC chromatographer takes extensive steps to eliminate them during sample preparation or trap them with guard columns. This has been an effective strategy for routine analytical methods,

but the need to work with ever lower concentrations of analytes creates the possibility of interactions with compounds of interest. As chromatographic instruments and techniques continue to advance, it can be seen that an unprocessed sample vial can potentially limit the ability to produce reliable results.

Low Particulate Background It has therefore become apparent that pre-cleaned vials are now required for today’s highly sensitive hyphenated techniques. As a result, the industry’s first pre-cleaned chromatography vials, National Scientific Mass Spec Vials, undergo a proprietary cleaning process, in a GMP compliant, fully validated clean room environment, which greatly reduces the background contaminants and their potential effect on high sensitivity chromatography. These certified mass spec vials undergo additional processing to remove trace artifacts introduced by manufacturing methods. Each production lot is then tested for particle counts, LC/MS and GC/MS background, according to a sampling plan designed to assure consistently superior performance from every vial. After processing, the vials are immediately packed into pre-cleaned, inert vial trays. Ultra high purity bonded PTFE/Silicone closures are packaged in an airtight, resealable container to further reduce the possibility of contamination. A series of studies have been undertaken to evaluate and verify the effectiveness of these precleaned vials. In the first study, particulate analysis of a typical unprocessed vial compared to the National Scientific Certified Mass Spec vials was carried out. All National Scientific Mass Spec Vials were processed and tested for background particulates. Table 1 shows the processed vial to have a significant reduction in total particle counts. A typical vial that has not been processed can exhibit particle counts exceeding 5000 particles per mL, with the highest counts occurring in the range below 0.5μm. This has traditionally been of little concern when GC inlet liners or HPLC

guard columns are used. However, GC techniques employing on-column injection create the need for a sample vial with minimal background particulates in order to prevent an accumulation of foreign material at the head of the column that might adversely affect a separation. Similarly, newer techniques employing finely packed HPLC columns, capillary columns and direct connection of the analytical column to the sample valve also require the elimination of as much particulate matter as possible from the sample stream.

Low LC/MS Background In order to further investigate the effectiveness of processed vials, samples of pre-cleaned Mass Spec vials and closures were exposed to acetonitrile at room temperature for two hours. Potential non-volatile organic compounds were determined using LC/UV and LC/MS with several different ionization techniques: positive electrospray, negative electrospray and positive atmospheric pressure ionization (APCI). Additional testing was conducted on samples exposed to acetonitrile for two hours at a temperature of 50°C to determine the effect of severe operating conditions. The results of the room temperature and 50°C appeared essentially the same, indicating that the background contribution from the processed vials is minimal over a wide range of conditions. Typical background scans for the room temperature exposure are shown in figures 1 and 2 using positive electrospray and negative electrospray ionization respectively. The top scan in each figure is the result of injecting the pure blank extracting solvent without exposure to glassware other than the original shipping container. The second scan for each figure represents an injection of an equal quantity of the extracting solvent after exposure to the pre-cleaned sample vial.

Low GC/MS Background A portion of the vial extracts prepared for LC/MS analysis was also taken for analysis Continued on page 16

DESIGN OF EXPERIMENTS HELPS OPTIMIZE

Pharmaceutical Coating Process

UPSHER-SMITH LABORATORIES FACED A PROBLEM with a fluid bed coating process that produced inconsistent results. Many of the coating parameters interacted with each other, so conventional one-factor-at-a-time (OFAT) experiments were unable to resolve the issue. Sarah Betterman, scientist for Upsher-Smith, used design of experiments (DOE) to determine how the key coating process parameters affect dissolution, the critical response. The designed experiment explained the inconsistency of the original process by showing that slight variations in atomization air volume, at those conditions, would have a large impact on dissolution. It recommended several scenarios with the potential to provide consistent coating performance. Upsher-Smith tested the three scenarios. They identified one that is consistently delivering results within specifications in production. Coating of a particulate using the Fluid Bed Wűrster HS™ Coating System involves repetitive movement of particles through an atomized spray region. During each cycle the particles are sprayed with a coating solution and then dried. Mass and heat are transferred between the three different phases involved in the operation – solid particles, liquid coating solution and gas jets. The complexity of the process is increased by the zones with high and low particle concentrations as well as high and low velocities. For example, too much atomization leads to premature drying of the coating material while too little may lead to over wetting and agglomeration. As a result, many coupled parameters affect the coating process.

lems, not to become immersed in statistics,” Betterman said. “That’s why I decided it was worth making a small investment in a software package that is designed specifically to apply DOE in an industrial setting. DesignExpert® software (from Stat-Ease, Inc., Minneapolis, Minnesota) provides a full range of experimental designs and statistical analysis behind a very simple user interface. So I can spend my time running experiments and interpreting the results rather than crunching numbers.”

Design of Box-Behnken experiment Betterman identified three factors that had historically been demonstrated to have the most impact on dissolution. They included: A. Product temperature B. Spray rate C. Atomization air volume

Initial coating parameters provided inconsistent results Upsher-Smith developed a commercial-scale manufacturing process for a new product based on a limited number of batches. As the company made more batches, inconsistencies appeared during the scale-up process. Betterman, who leads an initiative to implement DOE at the company, identified the application as well-suited for DOE because of the large number of factors involved and their complex interactions. “It would

take forever to try and optimize this operation using one-factor-at-a-time experiments because every time you changed a factor, you would have to re-optimize all of the other factors,” Betterman said. “Design of experiments examines all of the variables simultaneously so it enabled us to identify the optimum values for the factors much more quickly. At the same time, we captured information that gives us a better understanding of how the factors interact.” “The goal of DOE is to solve prob-

The responses were product dissolution as measured at five different time points. The dissolution was measured by immersing the product in dissolution media and quantifying the amount of the active ingredient

that has been dissolved at each time point. Betterman selected a Box-Behnken design, a response surface method (RSM) well suited to the goal of process optimization. The software developed a 16-run design which included 12 combinations of the factors plus four center points used to estimate pure error. A common bead blend was used to coat 16 batches in a fluid bed coater with a Wűrster insert.

Results shed light on multiple factor interactions Analysis of variance (ANOVA) revealed that a reduced quadratic model provides a good prediction of the percentage of drug releases at time point 1. The significant model terms (p<0.05) were A, B, C, AB, AC, BC and C2. The A and B effects can be examined graphically by looking at contour plots at various levels of C, for example, time point 1 with C at its low level as seen in Figure 2. This plot shows that a higher percentage of the product is released when product temperature (A) is low, spray rate (B) is high and atomization air volume (C) is low (the

NEWS upper left corner of the graph). These results were surprising because theory suggests that such wet conditions should reduce or eliminate spray drying, create a uniform film coat, and provide a slow release. Further examination of the product indicated that the coating film was compromised, most likely due to agglomeration under the wet processing conditions. The agglomerates broke apart during the process, causing picking. Picking creates small cavities in the surface of the film, resulting in a fast release. As the atomization air volume is increased to its middle value, the shape of the contours (Figure 3) remains the same but percent released decreases. The droplets are now smaller so the beads are not getting as wet and picking occurs less often. At a high atomization air volume, this response changes to having saddle behavior as shown in Figure 4. A contour plot of this situation is shown in Figure 5. This plot shows a smaller gradient through the design space, having a range of about 7 per cent as compared to 19 per cent with the atomization air volume at its low level. Also, the percentage released continues to decrease with an increase in the atomization air volume. Figure 5 shows that there are two areas with faster release, one most likely due to spray drying and the other most likely due to picking.

setup showed high variability, causing the dissolution results to fall outside 95 per cent confidence intervals, due to the low level of atomization air volume suggested. Another gave consistent results that closely followed the mod-

el’s predictions but the dissolution times were too slow, failing drug release specifications. However, one particular setup recommended by the software gave consistent results that passed specifications with little variabil-

Optimizing the coating process The DOE study demonstrated that at low- to mid-levels of atomization air volumes, a small change has a drastic effect on dissolution. On the other hand, at high levels, changes in atomization air volumes have a much smaller impact. This explained why the initial operating conditions provided inconsistent results. The models generated during the data analysis were used to optimize the coating process with the goal of consistently meeting the dissolution release specifications. The optimization generated six distinct scenarios, or sets of coating parameters, that were predicted to give good results. After examining the six suggested setups, three were selected to try on a production-scale process. One

Water Purification Millipore Corporation has released its ICW-3000 water purification system. The new system produces a constant and reliable source of ultrapure water for Dionex IC (Ion Chromatography) systems. Ultrapure water from the ICW-3000 system can increase the precision of IC analyses. The ICW-3000 system provides a continual flow of ultrapure water to the eluent generator and regenerant lines of the suppressor. This reduces the carbonate content in the water – sharply decreasing contamination risks and improving experiment reproducibility, while also eliminating the need for helium. The water system also eliminates the need for eluent preparation and the instrument downtime that occurs when filling eluent bottles. With only two tubes and one power cord to connect, the new system is designed for plug-and-play installation, as well as everyday use. The user fills the system’s 10 L tank with pure water in order to produce a constant flow of ultrapure water for the IC system. The ICW-3000 system is remotecontrolled by the Dionex IC system: both systems are 100 per cent compatible.

Sterilisation Cabinet The GLE-UVSC UV sterilisation cabinet provides effective decontamination of reagents and equipment before carrying out sensitive PCR reactions, particularly when amplifying DNA sequences which are either in limited supply or of low copy number. Four timer-controlled 15-Watt UV-C bulbs enable the user to control the exposure time and dose of high energy UV-C irradiation required to denature nucleic acids that cause unwanted background contamination, while a timer override switch allows the UV source to remain on indefinitely if preferred. Safety interlocks switch off the UV-C bulbs automatically when the cabinet side doors are opened, preventing accidental exposure to the UV source. The cabinet is constructed from UV-C-impermeable 10mm acrylic, which also serves as an effective barrier against radioactive isotopes, allowing the user to work in complete safety with high energy ß-emitters such as 32P. A single white light bulb illuminates the work area when the cabinet is in use.

Magnetic Stirring Bars Magnetic stirring bars, used to stir and mix everything from solutions in a cuvette to 55 gallon drums are standard equipment in many laboratory and manufacturing procedures. Traditionally covered in PTFE, the durability of magnetic stirring bars can be cause for concern in many applications including the mixing of granular slurries or when extended stirring times are required. Bel-Art Products has introduced Spinfinity™, a magnetic stirring bar that addresses these durability concerns and more. The Spinfinity™ magnetic stirring bar is an octagon shape with a built-in pivot ring. This shape provides a greater surface area than a rounded bar and the interrupted profile of the pivot ring reduces friction and chattering. In the lab, they can quickly be identified from other magnetic stirring bars by their distinctive purple color and are 3” x ½” in size.

FEATURE Continued from page 9 by GC/MS. As with the LC/MS evaluation the vials were exposed at room temperature and 50°C. There was no significant difference between the room temperature and elevated temperature test results. A typical GC/MS chromatogram and mass scan are shown in figures 3 and 4 using positive electrospray ionization, with blank solvent in the upper scan and the vial extract shown in the lower scan.

Conclusion In order to achieve improved levels of sensitivity, reliability, and reproducibility, today’s high performance hyphenated techniques require the elimination of all possible contaminants from every stage. The sample vial is an important link between the prepared sample and final analysis, and as such must also meet this requirement. Vials must, therefore, be produced

under the strictest automated manufacturing and quality controls systems to ensure a reproducible performance is obtained with every use. Studies have shown that the new National Scientific Mass Spec Certified vials exhibit minimal background particulate levels and minimal LC/MS and GC/ MS background contamination over a wide variety of conditions. Consequently, these new pre-cleaned vials are highly effective and offer the re-

assurance of meeting the rigorous demands of an extensive range of current highly sensitive chromatography applications.

New research service will increase access

TO PEER-REVIEWED MEDICAL LITERATURE Thanks to a new and exciting initiative, Canadian researchers can now contribute to a growing, searchable digital archive of published Canadian health research. Officially launched in 2009, PubMed Central Canada (PMC Canada) is a service that will act as both a national online archive for papers and data coming from government-funded research, but also as a tool for Canadian researchers to share knowledge, identify potential collaborators and expose their research to a global audience. Likewise, Canadians will have at their fingertips free access to the latest peer-reviewed health and life sciences literature, including research resulting from CIHR funding. “PMC Canada is a powerful tool that will help researchers build upon one another’s work and speed up the discovery and innovation process to address important health challenges,” commented Ian Graham VP, Knowledge Translation & Public Outreach Canadian Institutes of Health Research, adding that the site promotes knowledge sharing. “It will increase the visibility of CIHR-funded research so that it has the greatest possible value and impact,” he added. The first phase of PMC Canada includes a basic bilingual interface, a manuscript submission system for CIHR researchers and a bilingual help desk. Plans for the second phase of the repository will incorporate a customized web front-end along with enhanced reporting and alerting features for system funders and users. The site was established through a partnership between the National Research Council’s Canada Institute for Scientific and Technical Information, the Canadian Institutes of Health Research, and the US National Library of Medicine. PMC Canada, funded by the Canadian Institutes of Health Research, builds on PubMed Central, the U.S. National Institutes of Health free digital archive of biomedical and life sciences journal literature and is a member of the broader PMC International network of e-repositories. An advisory committee of Canadian health researchers and other stakeholders will guide PMC Canada’s future development.

Position: Principal Scientist Name: Chris Williams Company: Chemical Computing Group. Salary Range: $80,000 to $100,000 per year

What I do:

I use computers to help design drugs. The work varies; sometimes I’m in the office writing programs and other times I’m on the road showing clients how to use our software. I travel up to 90 days a year, mostly within Canada.

What education and skills do candidates need for this position?

Candidates require a degree in chemistry, preferably a PhD, some computer skills, and a background in math or physics. Most people in the field get their degree in computation or chemistry, or they’re hardcore computer programmers with a math and physics background. In terms of special skills, you interact with a lot of clients, so “the ability to work with people” is the most important. My advice to people interested in a job in the field is to keep your knowledge base as broad and general as possible. If you overspecialize and don’t see the big picture, you’ll find yourself with limited options.

What are the best parts of your job?

I have freedom over my own time, and my boss doesn’t check up on me. There are ways that I am accountable to him and things that I have to accomplish on my own, but I don’t have to punch a clock. When I tell people about what I do, they’re interested in the fact that I design drugs. It’s interesting to people, because it’s relevant to their lives. On occasion, friends have questions about medication, and sometimes I can give them relevant information.
