PSYC 314: Health Psychology (Review)

No matter which major you’re in, the Psychology program always provides an array of interesting courses to take. Out of them, PSYC 314 is a worthwhile option to look at, as you’ll learn about different aspects of how psychology applies to everyone’s health, from day-to-day life to clinical settings.

Format of the course

PSYC 314 is a typical course with 3 hours of lectures per week. Sit in lecture, take notes, ask questions. The topics covered include stress and coping, health-related behaviours, health service utilization, pain, and chronic and life threatening illnesses, all from a psychosocial point of view.

The evaluation differs depending on which instructor you have. You can take a look at previous syllabi for the course here! With Dr. King, I had 3 equally weighted non-cumulative exams (2 midterms + final) with the option to write a paper, in which case all four assessments would be worth 25%. There was also a bonus 3% possible from HSP credits. If you’re a good writer, I highly recommend doing the paper!

With my prof, each exam consisted of half multiple choice questions from the textbook and half written questions from the lecture. The textbook questions were probably the most difficult as they sometimes required you to draw on extremely specific details. I recall one of the questions I had asking about the mechanism of action of a drug, which was a surprisingly sciencey question for a course with arts credit! Continue reading

CHEM 313: Advance Organic Chemistry for the Life Sciences (Review)

A unique organic chemistry course with an emphasis on application and minimal requirement for memorization! CHEM 313 is a third year organic chemistry course that highlights different synthetic pathways in making peptides, carbohydrates, and nucleic acids.

Format of the course

The format for CHEM 313 was pretty standard for an organic chemistry course; a lecturer that goes through different reactions each class. Be aware that this course runs at 8 am, so remember to bring your coffee. Professor Sherman gives 1-3 minute joke break every class which makes waking up so early more bearable.

A recent change to the course is the allowance of a cheat sheet to midterms and finals. This sets it apart from almost every organic chemistry course at UBC – which require in-depth memorization of all the reactions and mechanisms learned. This being said, CHEM 313 evaluations focus more on approaching new problems based on mechanistic rationale that was taught in class (which also makes it a difficult course). Continue reading

Food and cyanogenic glycosides

Natural poisons are abundant in the foods we eat every day, such as in apples, peaches, chickpeas, lima beans, bamboo shoots, flaxseeds… [1] In all of these examples, a class of chemicals called cyanogenic glycosides are responsible.

Glycosides are simply molecules where a sugar is bonded to another group. For example, in adenosine, one of the nucleosides in RNA, an adenine nitrogenous base is bonded to a ribose sugar. Meanwhile, the term cyanogenic refers to the nitrile moiety in the molecule, also known as a cyano group.  So, a cyanogenic glycoside is just a sugar molecule that has a cyano group attached somewhere.

Cold showers and sympathetic activation

Have you ever taken an ice-cold shower, dumped a bucket of ice water on your head, or leaped into a freezing cold lake? You might have felt a sudden jolt of adrenaline rushing through your body, with your heart pumping faster and your breathing rate increasing.

When the body is submerged in cold water, cold receptors in the skin activate of the sympathetic nervous system, known for causing the so-called “fight-or-flight” response. These responses include increased blood pressure, increased heart rate, and increased breathing rate, which are all immensely useful during physically stressful situations. The metabolic rate also drastically increases as the body attempts to heat itself up; in fact, previous studies have recorded up to 350% increases in metabolism when study participants were immersed in 14°C water!

BIOL 340: Introductory Cell Biology Laboratory (Review)

Endless reports and hours in the lab; the bane of all Biology major’s existence: BIOL 340. As its name suggests, BIOL 340 is an intense lab that teaches different cell biology techniques, from fluorescence microscopy to SDS-PAGE.

format of the course

BIOL 340 is a 3 hour weekly lab course with a separate 1 hour lecture portion. However don’t be fooled, often most of the class were unable to finish on time and labs ended up being on average 4-4.5 hours long. Since each lab featured a new lab technique, pre-readings were very dense. There were also in-class pre-reading quizzes, so memorizing every little detail was crucial (imagine spending hours reading about the different steps in SDS-PAGE, but then being asked what SDS stands for…).

These labs were usually done in a group of four of five (random partners), and I was lucky to be in a good group. Each group was given a different mutant yeast strain to practice on using the lab technique of the week. In the later parts of the course, we had to run an independent study on this same yeast strain, which was by far the most stressful portion of the course. Continue reading

Glow sticks and luminescence

Everybody knows those popular fluid-filled sticks that glow vividly in the dark. They’re popular at dances, raves, and other events. But what exactly is going on? How does bending the stick make them glow? What is even glowing in the first place?

Glow sticks rely on a property called chemiluminescence, where some of the energy released from a chemical reaction is emitted in the form of light. This energy is usually derived from the breakdown of hydrogen peroxide contained within a fragile tube inside the stick, which forms high-energy intermediates. [1] Continue reading

Everything You Need to Know About COVID-19

Who would have thought that the mere 27 cases of pneumonia in Wuhan, China would end up throwing the world into turmoil? On March 11, 2020, COVID- 19 was declared a pandemic by the World Health Organization, and since then, researchers worldwide have been trying to develop a vaccine. As of now, researchers have identified some parts of how the virus works, how it’s transmitted, and ways we can slow down its spread.

how did covid-19 arise?

COVID-19 is similar to most animal viruses in that it is an infectious genetic element packaged in a lipid membrane with associated membrane proteins. Upon sequencing of this element and comparisons to different coronavirus strains, researchers have determined the virus to originate from bats.

However, these comparisons also showed that humans did not contract the virus directly from bats. Instead, it is likely that the virus was transmitted through an intermediate host, pangolins.

BIOL 300: Fundamentals of Biostatistics (Review)

We all know statistics courses can be relatively dry, but BIOL 300 spices things up with interesting biological examples! BIOL 300 is an introductory level statistics course at UBC, which fulfills the statistics requirement for life science majors.

format of the course

The format of this course is usually what you see in most science courses. What makes this course unique is the lab component, where you learn computer coding. Wait … computer coding in a statistics course? It turns out that most statistical analyses are tedious to do by hand, so instead we learned how to automate these calculations. In class, we learned about the different statistical approaches for different contexts, while in lab we learned how to actually run these analyses. Continue reading

Tips to Ace Your Classes

Whether you’re a fresh first year or a seasoned fourth year, a good study routine is essential to doing well in school. Here are some tips, that I personally follow!

Taking notes in class

Many people tend to use a notepad/notebook to lectures fore notetaking; however, I discourage you from doing this. This is an inefficient form of note-taking, because people tend to copy down what’s shown on the slides instead of paying attention to the lecturer! Instead, I encourage you to bring a device, where you can annotate the (usually posted) pre-lecture slides. By doing this, you can write down things that the lecturer mentions, which are NOT on the slides and be more engaged.

In this regard, I personally used an iPad and apple pencil. It keeps my backpack light and all my notes in one place. I strongly recommend investing in one, or a similar note-taking device. Continue reading

PCTH 325: Rational Basis of Drug Therapy (Review)

Ever wanted to learn about drugs, but in a stress-free course? Well PCTH 325 is the course for you! PCTH 325 is a pharmacology course at UBC, targeted towards life science students. The goal of this course is to inform students about the common drugs used to treat illnesses in different body systems, as well as give a glimpse into how new drugs make it to the market.

Format of the course

I found the format of this course to be more unique than your average science course. There is no single lecturer in this course, instead, there is a new lecturer every two or three lectures. The backgrounds of these lecturers are incredibly expansive, ranging from an anesthesiologist to a statistician, who are all experts in their portions of the lectures! I came out of this course feeling more informed and appreciative of the pharmacology field. Continue reading
