Typically, cancer is difficult to diagnose at the initial stage. This early-stage diagnosis reduces its complications and the mortality rate linked with it. In many countries, cancer is usually diagnosed in later stages which affects the quality of life and results in greater morbidity rates and high treatment costs. Addressing the delays in the detection of cancer and the unavailability of effective treatment is therefore critical in all the health care settings for cancer control.
Early diagnosis strategies are used to confirm the presence of disease, monitor the process of disease and plan interventions to prevent the disease from progression. These strategies help to improve the cancer outcomes by providing care and effective treatments at the initial stage.
Factors that hinder the cancer diagnosis must be identified and addressed so that it becomes easy to implement effective treatment programs at various levels including improving diagnostic and referral capacity, community engagement to address the behavior of the patient, and ensuring the timely access to high-quality treatment.
A team of researchers led by Professor Jenny Yang from the Georgia State University Regents identified a new method for detecting cancer at the initial stage. This method used the target MRI contrast agent that binds with proteins and detects cancer. The study is published in journal Science Advances.
To detect the metastases of the liver, new biomarkers have been identified by Yang and her colleagues at Georgia State and Emory University. Currently, cancer is diagnosed in its late stages such as biopsies. At this stage treatment options become limited and it ultimately lowers the survival rates. The recent discovery discussed in this study provides a wide range of options that includes precise treatments, effective diagnosis and reduce risk for patients.
Yang said that this method is effective as it will have many applications for diagnosis and treatment of any type of cancer. This method is already used in the lab for 10 different types of cancer.
National Cancer Institute-funded this researcher project. Researchers developed an agent which can target specific receptors known as Chemokine receptor 4 (CXCR4). In the cancerous cells, this receptor is expressed more than normal in metastasis organs such as the liver.
It would be expected that small instances of cancer can be diagnosed through CXCR4 targeted protein-based MRI contrast agent because it beats all the barriers that hinder the early diagnosis of cancer. This new methodology shows the cancerous cells on multi-color scans known as precision MRI (pMRI).
In MRI technology, Gadolinium is used in contrast to agents that enhance the quality of images. In her previous research analyzing calcium, Yang decided to check the interaction of the metal with proteins. She found that the element wraps the protein around itself and takes it to the site where the image is being formed.
Still is it difficult to diagnose cancer in the early stages even though invasive biopsies. The diagnostic tests that use these contrast agents not only detect the presence of cancerous cells but can distinguish the diseases into different stages. The beauty of this test lies in its high accuracy and sensitivity.
The U.S. Food and Drug Administration used the targeted protein contrast agent in the first step of clinical trials to check its efficiency in humans. Yang hopes that these clinical trials in patients will be conducted within 18 months to two years.
Yang is an associate professor at the Center for Diagnosis and Therapeutics. She enrolled 18 foreign and 17 U.S patients in protein engineering. Recently, the National Academy of Inventors awarded her a fellowship. Also, she has started a new company ‘InLight Biosciences’ that allows her to compete for new findings and introduced her latest discoveries to the world.
This research is based on the 2019 study published in the journal Nature Communications. In this study yang and her team identified liver fibrosis for the first time by using a collagen targeted protein contrast agent.
Yang further added that this contrast agent is used for more than 30 years in different aspects and it is my biggest contribution to the scientific world and hoping for the more to come in the future.
News Update: Four Children Targeted Due to Cannabis-Laced Sweets
Cannabis gummies and sweets containing THC are available in the market, but these edibles are for people above the age of 18 or 21. The age limit to consume cannabis containing gummies and other sweets vary from state to state and from country to country.
The rules and regulations relating to cannabis-laced sweets differ depending upon the government’s decision regarding the use of controlled substances in edibles. Moreover, in some areas, the sale of cannabis gummies is permitted but with age limitations. Unfortunately, the incidence of children getting sick after taking marijuana, THC, or cannabinol-containing sweets have occurred in England and Ireland.
Consumption of younger kids can be injurious to their health, and it may lead to hospitalization, being in a coma. In severe conditions, excessive consumption of these marijuana-containing sweets can result in death, reported Food Safety News.
The Incident Related to Cannabis Consumption by Children
In England, four young children have to be admitted to hospital when their condition becomes worse after supposedly consuming cannabis containing sweets or gummies. One of the four children aged 12-years-old was discharged on the first of May, but the other three children were to be released after a day. Once they have been monitored for a day or overnight, they were likely to be released.
Three children, two of age twelve years old ( a girl and a boy) and one of age thirteen years old who was a boy when eating jelly sweets their body reacted vigorously and they begin to vomit uncontrollably. Furthermore, these children experience episodes of unconsciousness as they become conscious and unconscious abruptly.
How Did these Sweets Cause Severe Sickness in Reported Children?
There have been different incidents with a similar situation where children have experienced sudden reactions after eating sweets or jellies. Police in Surrey is trying their best to find the root cause of such severe reactions. These children do experience vomiting and remain unconscious for some time, but fortunately, they did not develop any long-term disease. Neither did they experience any ill-effects, and authorities are eager to find the root cause and source of these sweets.
Another incident of such reactions also occurs when children consume jelly apple rings that appear as green jelly circles. Similarly, some pupils in South London also need quick treatment care and hospitalization due to reactions that develop after the consumption of gummies containing cannabis. According to Detective Sgt. Lisa Betchley, police are determined to find the source or where children are getting such sweets. There is some evidence that children purchased these sweets or gummies online.
She further added that these children were lucky to survive as they received help from two nearby medical students when the children developed reactions to sweets. Medical students have been assisting the South East Ambulance Service.
They have also been aiding hospital staff in various treatment and repaid responses. The sale of such types of sweets containing cannabis is illegal. Some products are on the market in the finest packaging, but people shall avoid using them as they are illegal in the UK.
Sickness Reactions Occur in Ireland
Individuals that possess cannabis-containing products for sale or usage shall keep them within storage conditions. It is essential to keep these items out of reach of children as they can be detrimental to their health.
Cannabis containing edibles is not for teenagers and children. The substance is considered under controlled drug. Seeing an increase in the number of such reactions in children after consuming cannabis-containing sweets, the FSAI issued warnings. A Food Safety Authority of Ireland warning highlights the potentially dangerous aspects of edible THC products.
According to Pamela Byrne, sweets and jellies containing active ingredients of the marijuana plant are denoting sold through online means. Those involved in such activities do not care about the safety of children and the consequences of their activities.
Variety Of Marijuana Strains Yield Different Health Impacts
Marijuana is a plant that has many beneficial medical uses. Moreover, researchers are discovering more and more about the effectiveness of cannabis in treating various psychological and pathological conditions. The plant has been gaining popularity for its health effects.
Marijuana is effective in reducing pain and anxiety. It is also applicable for elevating the quality of sleep, and recently it is famous for being an aphrodisiac. The impact of various strains of cannabis is different.
Marijuana strains are classified as indica, Sativa, and hybrid. However, the classification is considered controversial. Moreover, each variant-strain of cannabis generates a specific effect. But personal preferences also determine what individuals will use and how it will affect them.
Are There Any Marijuana Genital-specific Strains?
There is no evidence of the existence of marijuana strains that can result in genital-specific arousal. However, cannabis is usable for treating and helping to ease certain penis-specific situations. Moreover, individuals with anxiety associated with erectile dysfunction can take the anxiety-reducing strain of cannabis.
According to a 2017 study, marijuana use has a positive link with sexual frequency. Moreover, according to some studies, cannabis users have sex more often. Furthermore, there is a possibility that cannabis leads to increased libido levels.
However, some research studies disagree with cannabis having a positive association with sex. According to a 2011 literature review, frequent marijuana use can cause erectile dysfunction. There is another study of 2010 that links daily use of weed to the inability to achieve orgasm.
Thus, further research is essential to understand the true-effect of marijuana on sexual health. However, without sufficient evidence, people are still using cannabis to enjoy sex, boost their libido, and deal with other undesirable symptoms like pain or depression.
Various strains of cannabis generate different effects on different individuals. So far, there is no guarantee of which cannabis-strain will be beneficial for your sexual health. Moreover, it is wiser and safer to use marijuana strains with the recommendation of doctors and under their supervision.
Strains For Arousal
The two strains most frequently used for enhancing libido are Sativa-dominant hybrid (Sweeties) and hybrid (OG Kush). Sweeties contain 22 percent THC, while OG Kush contains 18 percent THC.
Sweeties produce euphoria and are usually used for relieving stress, anxiety, and low libido. OG Kush has a reputation for generating happy feelings. However, the usage of OG Kush makes consumers a little sleepy. Thus, consuming it in small doses is safe and effective.
Treating Depression With Cannabis Strains
Depression can lead to multiple conditions including erectile dysfunction, lethargy, fatigue, and low sex drive. Many individuals use Strawberry Diesel and Jillybean to treat depression. Both are hybrid marijuana strains.
Jillybean and Strawberry Diesel strains contain zero CBD, but both have 16 percent THC each. Moreover, jellybean is energizing, produces euphoria, is a mood elevator, and perfect for combating depression. However, Strawberry Diesel does have a euphoric, mood uplifting effect, but it is not too energizing. Moreover, it is not sleep-inducing and thus is useable during day time.
Getting Rid Of Anxiety And Stress With Aid Of Marijuana Strains
Stress and anxiety are both common libido killers. Moreover, stressed individuals are unable to enjoy and have fun. Furthermore, stress can lead individuals to exhaustion, brain fog, and irritability. It also decreases the potential for sexual pleasure. However, the use of marijuana strains will enable the consumer to reduce stress levels and soothe anxiety.
Sherbet and Locktite are hybrid strains of marijuana containing 18 percent THC capable of producing euphoria. For arousal, individuals use Locktite, and Sherbet is effective for erogenous play.
Moreover, if individuals desire to use more energetic strains, they can use Durban Poison and Harlequin. Both have Sativa-strain of marijuana, but Durban Poison contains 17% THC, and Harlequin contains 5% THC.
Cannabis Greenhouse Effect – Areas With More Emission
Cannabis can cause climate change that can affect the environment and life of human beings, reports The Conversation. The extent to which marijuana contributes to environmental alterations depends upon its cultivation technique and location.
The marijuana industry is expanding, and lawmakers are working on legalizing its cultivation, possession, and other activities across the United States. The cultivation of cannabis can occur indoor and outdoor. However, the effects of cultivating marijuana indoors are different from its cultivation in open outdoor fields.
According to a recent study, cultivating cannabis indoors results in the production of large amounts of greenhouse gasses. Moreover, the impact of these gasses depends upon the location where cannabis indoor cultivation occurs.
Energy For Cannabis Indoor Cultivation
Cultivating cannabis indoors requires a controlled environment and source of energy, light, water, and other suitable conditions. A lot of electricity is utilized in producing sufficient light for the cultivation and growth of marijuana indoors.
Moreover, cannabis cultivation at an optimal growth rate requires a lot of energy. Energy is essential for producing a comfortable growing environment for the marijuana plant. Furthermore, air conditioners and heaters are essentially required to keep the temperatures within a suitable range.
The growth and cultivation of plants require the presence of a certain percentage of carbon dioxide. Thus, cannabis producers pump carbon dioxide into the indoor marijuana cultivating unit. However, apart from the beneficial effect in the growth of cannabis, carbon dioxide contributes to 11% to 25% of greenhouse gas emissions in facilities.
Producers require a proper ventilation system that allows clean, fresh air at a suitable temperature and humidity levels to enter the indoor cultivating unit of cannabis. Availability of air is essential for growth but cleaning it and correcting its temperature and humidity is possible with an energy-intensive process.
Intensive energy and other production requirements increase greenhouse gas emissions. Moreover, in some regions, the emission of greenhouse gasses is higher than in other localities.
Areas With More And Less Greenhouse Gas Emissions
Regions with milder climates require less heating and air conditioning. Moreover, their electric grids use more clean energy. As a result, greenhouse gas emissions in such regions are less than in other areas.
According to Department of Energy, Environmental Protection Agency, and industry data, growing pot cannabis indoors results in greater emissions of greenhouse gasses in the Mountain West, Midwest, Alaska, and Hawaii in comparison with Pacific and Atlantic coasts.
Moreover, cannabis in southern California has the lowest emissions, and eastern Oahu in Hawaii has the highest greenhouse gas emission. Greenhouse gas emissions in Southern California are at 143 pounds of carbon dioxide, equivalent per ounce of dried marijuana. However, 324 pounds of carbon dioxide equivalent per ounce emission occurs at Oahu in Hawaii. Moreover, this emission is equivalent to burning 16 gallons of gasoline.
Greenhouse Emissions From Cannabis And Its Impact
The emission rate affects the environment, but authorities, cultivators, and industrialists do not consider the environmental impact. There is an urgent need to take measures regarding the greenhouse effect of cannabis cultivation to control the possibly worse situation.
There are old warehouses that use outdated equipment that emit more greenhouse gasses as they are less energy efficient. Furthermore, there is a need for developing new better techniques for growing high-quality cannabis with energy-efficient methods.
Unknown variations in the cultivation process and growing methods make it hard to design effective policies that can enable producers to limit the emission of greenhouse gasses. Moreover, one serving of THC, roughly 10mg dried-flower, yields more greenhouse gasses emission than a serving of beer, wine, spirits, coffee, cigarettes.
Furthermore, it is better to cultivate and grow cannabis outdoors in open fields with a suitable environment as it will lower the emission of greenhouse gasses.
