Types of injections and syringes . • Intramuscular injection • Intradermal injection • Subcutaneous injection • Intravenous injection Intramuscular injection deliver the substance directly inside the muscles, suitable choice of gauge will be 20g-23g. Intradermal injection is where the needle is injected just beneath the dermis, below the epidermis of the skin. Preferred needle gauge for a intradermal injection ranges from 25g to 30g. Subcutaneous injection are well known for a the injection of insulin for people suffering with diabetes,  needle gauge ranges from 25g to 30g as they are the most efficient in delivering the liquid in between the skin and muscles.   Intravenous injection is where the needle is injected directly into the veins and hence the bloodstream, using the needle gauge between 20g and 25g.

Chemical Basis for Love: Duration of love is 1 to 3 years.   Love can be divided into three categories: lust, attraction, and attachment. Though there are overlaps and subtleties to each, each type is characterized by its own set of hormones - * Testosterone and estrogen drive lust * dopamine, norepinephrine, serotonin create attraction * oxytocin and vasopressin mediate attachment.       These hormones stimulate the brain’s pleasure center leads to increased heart rate, intense feeling of excitement, making us giddy, energetic, euphoric, even leading to decreased appetite and insomnia – which means you actually can be so “in love” that you can’t eat and can’t sleep.  First stage - Lust , these chemicals turn off regions in our brain that regulate critical thinking, self-awareness, and rational behavior, including parts of the prefrontal cortex . In short, love makes us dumb. Have you ever done something when you were in love that you later regretted?     Research has indicated that this second stage - Attraction, generally lasts from one and a half to three years.     Last stage of love is Attachment which is is generally based on commitments such as marriage and children, or on mutual friendship based on things like shared interests. #love #basisoflove #hormones

Long term Marijuana use can cause premature aging, fear and paranoia. Long term, heavy cannabis use causes significant damage to parts of the brain mainly hippocampus and amygdala that regulate memory and emotion, Australian researchers have found in a world-first study. The team scanned the brains of heavy users and found never seen before shrinkage of the parts known as the hippocampus and amygdala. The changes were the equivalent of minor brain damage or premature aging,  The hippocampus helps turn an experience into a memory that can last longer than a few minutes. It has also been linked to navigational abilities. Taxi drivers have been found to have bigger-than isual hippocampus The amygdala also helps lay down permanent memories and cues our emotional response to the world. Damage to this part of the brain can lead to emotional problems such as irrational fear or phobias and paranoia. #health #cannabis #marijuana #weed

Optical coherence tomography angiography (OCTA)  OCTA is a non-invasive imaging technique known as optical coherence tomography (OCT) developed to visualize vascular networks in the human retina and choroid.    OCTA uses low-coherence interferometry to measure changes in backscattered signal to differentiate areas of blood flow from areas of static tissue. To correct for patient movement during scanning, bulk tissue changes in the axial direction are eliminated, ensuring that all detected changes are due to red blood cell movement. This form of OCT requires a very high sampling density in order to achieve the resolution needed to detect the tiny capillaries found in the retina. Recent advancements in OCT acquisition speed have made it possible the required sampling density to obtain a high enough resolution for OCTA. This has allowed OCTA to become widely used clinically to diagnose a variety of ophthalmological diseases, such as, age related macular degeneration (AMD), diabetic retinopathy, artery and vein occlusions, and glaucoma. #ophthalmologist #ophthalmology #oct
