HGH: Side Effects in Men and Women – Healthline

Overview

Human growth hormone (hGH) is a naturally occurring hormone produced by the pituitary gland. Its important for growth, cell regeneration, and cell reproduction.

HGH helps to maintain, build, and repair healthy tissue in the brain and other organs. This hormone can help to speed up healing after an injury and repair muscle tissue after exercise. This helps to build muscle mass, boost metabolism, and burn fat.

HGH is also said to benefit the quality and appearance of the skin. Its said to slow down the aging process and treat age-related diseases. However, research supporting these claims is limited.

HGH works by stimulating metabolic processes in cells to activate metabolism. It stimulates the liver to make an insulin-like protein that produces cartilage cells. This plays a part in bone and organ growth, as well as muscle protein synthesis.

Although hGH is a naturally occurring substance, its also available in synthetic forms as a treatment or supplement. But what are the risks of taking it?

Synthetic hGH is used to treat poor growth in children and adults. It can also be used to treat adults with short bowel syndrome or muscle loss due to HIV or AIDS.

Lack of growth may be the result of medical causes such as:

Injections of hGH can help people with a growth hormone deficiency to:

Because of these benefits, many people use hGH to enhance their athletic ability. Its sometimes used in combination with anabolic steroids to increase muscle mass and to enhance athletic performance.

Some people believe hGH has anti-aging effects since natural levels of hGH decrease with age. Its also said to naturally increase testosterone. However, it should be noted that not all of these benefits have been scientifically proven. The use of hGH for athletic and anti-aging purposes is controversial due to this lack of scientific evidence and its potential side effects.

HGH is injected intramuscularly (IM) and subcutaneously (under the skin) if its been prescribed. Sometimes, illicit manufacturers offer hGH in an injectable form as well.

HGH and substances that promote hGH production are sold online by some companies as dietary supplements, which claim to have the same benefits as the injections. These supplements are sometimes known as human growth hormone releasers. Some of them are said to increase hGH levels in your body because of ingredients such as amino acids.

However, theres no evidence that these supplements have the same results as prescribed hGH. Homeopathic remedies containing human growth hormone also exist. Evidence supporting their benefits is lacking.

SeroVital is a popular brand of dietary supplement. Its said to be able to naturally raise hGH levels because of the amino acids it contains. This is said to have an anti-aging effect. SeroVital also claims to build stronger bones, increase lean muscle mass, and reduce body fat. These claims need more study. SeroVital contains no hGH.

There are several side effects that may go along with hGH use. These side effects are possible with the prescribed version, as well as an illicit form of hGH since the content isnt completely known and regulated. Side effects may affect older adults more than younger people. The long-term effects of hGH arent known.

Possible side effects of excess hGH injections include:

Possible side effects of SeroVital differ from those of hGH since SeroVital is an amino acid blend that doesnt contain hGH. Side effects of the amino acids in SeroVital may include:

HGH should be used with care and consideration. Only use hGH that you get via a doctors prescription. Check in regularly with your doctor while youre taking it.

Take special care to note how your body reacts and if you experience any adverse reactions. If you wish to strengthen your body or improve your health but dont have a condition known to cause growth hormone deficiency, you may consider finding other ways to do this. Eat a healthy diet, exercise regularly, and engage in healthy habits to improve your overall health and well-being.

Sleep deprivation affects both students and staff – The Tide

Junior Ryan Whittaker fights to keep his eyes open. The voice of his teacher echoes in the distance. He puts his head on his desk. But no, Whittaker invokes his inner strength and combats the persistent desire to fall into a deep lull.

Struggling to stay awake is a common issue among high school students. This year, the amount of students who have been caught sleeping in class spurred the creation of @RMsleeps, an Instagram account exposing victims of sleep deprivation.

According to The American Academy of Sleep Medicine, teenagers need eight to ten hours of sleep per night. Unfortunately, 72.7 percent do not get close to this amount.

Getting enough sleep is essential, especially for teens. Teenagers have a particularly strong need for sleep because theyre undergoing so many profound changes to their physical body, their emotional health, their mental health and their brain function, Dr. Nancy Kadowitz, a pediatrician at Capitol Medical Group, said.

Lack of sleep may cause students to miss out on growing a couple inches taller. Growth hormone is excreted at night while youre sleeping, Dr. Kadowitz said. If you deprive yourself of sleep, you deprive yourself of growth hormone, which helps you reach your growth potential.

If you deprive yourself of sleep, you deprive yourself of growth hormone, which helps you reach your growth potential.

Dr. Kadowitz

US History teacher Amber Myren is aware of this impending issue. I ask my students frequently how much sleep theyre getting, Ms. Myren said. They always tell me Im getting three hours, or Im getting four hours. Whittaker gets around six hours a night, while senior Rosa Darko gets four hours on average, but sometimes, just one.

Many teens find it difficult to get to sleep early because of a biological shift in the bodys circadian rhythms during puberty. A teens sleep schedule is shifted back by two hours, meaning someone who used to fall asleep easily at 10 p.m. will, as a teen, not feel tired until midnight.

High schoolers are kept up at night due to academic obligations, extracurriculars and other responsibilities. It is common for students to stay up well past midnight doing homework. Many pull all-nighters when they have an upcoming test or assignment.

Some may also put off their sleep to unwind after a long day. Before I go to bed, I might be texting friends or I might be on Twitter, just like the students, Ms. Myren said. I know youre not supposed to look at your phone, but I do it anyway.

Even though students stay up late into the night to work, they still must get up early for school. Many get up before 6 a.m. to catch buses.

The American Academy of Pediatrics recommends that school starts at 8:30 a.m. so that teens can get their much-need sleep. However, at RM, classes start at 7:45 a.m.

When their alarms go off, students rarely feel prepared for the day to come. I cannot think when I first wake up, I just want to go back to sleep, Whittaker said.

Waking up groggy and angry is not a healthy way to start a day, but it is the reality. I feel pissed. I feel annoyed. I dont want to wake up in the morning, Darko said.

Many people lay in bed for a while after their alarm rings. Its hard to make the transition from bed to standing, Ms. Myren said. My brain is so foggy, I cant think about all the fun things that are going to happen during the day.

This fogginess stays with students throughout the day, impacting how they work and their stress levels. It definitely heightens my anxiety surrounding school and how stressed I am, Darko said. I tend to be a little bit more antsy when Im taking my test and a little bit absent-minded throughout the day, and I cant pay attention in class. Students want to work, but they often feel too exhausted.

For Ms. Myren, being tired causes internal fear about her teaching abilities. What I get stressed about is am I a good enough teacher if Im feeling low energy that day, she said. Can I be energetic and interesting if Im having a day where Im so tired?

Sleep deprivation impacts other areas of life outside of school. One of the biggest is risk-taking. Your frontal lobe is still developing, and thats how you control your impulse behavior, Dr. Kadowitz said. [A sleep-deprived teen] might engage in more high-risk behaviors. Teens are more likely to take drugs or text while driving when their minds are clouded by tiredness.

Sleep deprivation often leads to irritability and can exacerbate conditions like depression and anxiety. It lessens cognitive ability, lowering memory, attention span and creativity. Being overly tired all the time often leads to a slip in grades.

Sleep deprivation also affects social well-being. It can affect their peer relationships because if youre impulsive with friendships, that can get you in trouble, Dr. Kadowitz said. So academics suffer, relationships suffer.

Students and teachers must work towards making sleep a priority and having a consistent sleep schedule. A baby step is to do something relaxing before bed not including using electronics, which stimulates the brain.

Most students know that they should be sleeping more than they are and wish that they could go to bed earlier. However, this does not change the amount of homework they get, or how early they must get up for school. Unfortunately, it is almost impossible for high school students to get the eight to ten hours they need, and they are feeling the effects.

Researchers Have Discovered an Exercise Sweet Spot To Reverse Cognitive Decline – SciTechDaily

Researchers find out how exercise improves learning.

University of Queensland researchers have discovered an exercise sweet spot that reverses the cognitive decline in aging mice, paving the way for human studies.

After more than a decade of research, led by Queensland Brain Institute (QBI) Emeritus Professor Perry Bartlett and Dr. Dan Blackmore, the team found 35 days of voluntary physical exercise improved learning and memory.

We tested the cognitive ability of elderly mice following defined periods of exercise and found an optimal period or sweet spot that greatly improved their spatial learning, Dr. Blackmore said.

The researchers also discovered how exercise improved learning.

We found that growth hormone (GH) levels peaked during this time, and weve been able to demonstrate that artificially raising GH in sedentary mice also was also effective in improving their cognitive skills, Dr. Blackmore said

We discovered GH stimulates the production of new neurons in the hippocampus the region of the brain critically important to learning and memory.

This is an important discovery for the thousands of Australians diagnosed with dementia every year.

Dementia is the second leading cause of death of all Australians, and with no medical breakthrough the number of people with dementia is expected to increase to around 1.1 million by 2058.

Professor Bartlett said the findings provide further proof that loss of cognitive function in old age is directly related to the diminished production of new neurons.

It underlines the importance of being able to activate the neurogenic stem cells in the brain that we first identified 20 years ago, Professor Bartlett said.

The team was able to explore how the production of new neurons changed the circuitry in the brain using Magnetic Resonance Imaging (MRI).

Using MRI, we were able to study the brain following exercise, and for the first time identify the critical changes in the structure and functional circuitry of the hippocampus required for improved spatial learning, Dr. Blackmore said.

Hasbulla Magomedov: Everything about the Internet Sensation – TheTealMango

If you are active on Tiktok or interested in combat sports then in all likelihood you might have heard about Hasbulla Magomedov.Hasbulla has become an internet celebrity this year. We will bring all the details pertaining to him in our article today.

Many celebrities like Joe Rogan spoken, Logan Paul, and MMA fighter Rafael Fiziev have mentioned his popularity on various forums.

If you have been looking around to find out more details about the internet sensation Hasbulla Magomedov, keep scrolling!

Hasbulla Magomedov was born in the year 2003 in Dagestan, Russia. Even though he is now 18 years old his face looks like a baby with a high-pitched voice.

There are unconfirmed reports that Hasbulla suffers from a disease called, Growth Hormone Deficiency (GHD), which is a unique kind of dwarfism.

He is a blogger by profession and keeps posting content on the social media platform, Instagram. He is active on the social networking service TikTok as well. The majority of his posts are either pranks or related to spoofing videos about MMA.

Hasbullas ill fame was because of his larger-than-life personality. During the lockdown phase of the coronavirus pandemic, he began posting details about his life on Instagram and Tik-Tok. As per some of his posts on social media, it seems like he is a hot-headed temperament. He is also into martial arts training like boxing and wrestling.

He was at the peak of his popularity in May 2021. Hasbulla has displayed his charisma and trash-talking skills with 17-year-old Tajikistan singer Abdu Rozik during his pre-fight conference.

Hasbullas height is just around one meter tall that translates to just 33. His weight is around 16 kilos.

Hasbulla is a popular personality among the MMA community and is often referred to by his nickname Mini Khabib.

There was one video compiled by him where he was seen reenacting Khabib Nurmagomedovs iconic UFC weigh-in so users gave him this nickname. After this video went viral on social media the two became good friends and appear frequently in videos together.

Looking at their close friendship few people started speculating whether Hasbulla and Khabib are related, however that isnt the case.

His most famous video to date is his pre-fight press conference that featured Abdu Rozik (social celebrity) where the two were seen trash-talking and brawled.

Their rumored MMA fight was organized by Chechen MMA fighter Ashab Tamaev. This led to speculation among his fans about when is the Hasbulla vs Abdu Rozik fight. However, the date is not yet decided.

The Sports Association of Little People of Russia has branded the fight as unethical. It is still uncertain if this is one of the reasons why there is a delay in the announcement of the date.

Hasbulla is seen more often taunting the likes of UFC star Connor McGregor that has led to more love to the MMA and casual community.

There is no concrete information available in the public domain about Hasbulla Magomedovs net worth.

Some speculate that his net worth is more than $100,000 given his display of luxurious life in his videos. However, now that he has become an online celebrity his wealth is expected to go up significantly.

Even though there was criticism and backlash, Hasbulla is still making videos and his presence is felt in the MMA world.

Recently he was seen in skit videos demanding a huge amount in millions of dollars in cash for his fame and potential fights in the near future. This implies that he has a strong desire to rise to the top.

Even though there is no official confirmation about his disease however it is considered that Hasbulla is suffering from some kind of dwarfism. Because of the genetic disorder, Hasbulla has childlike characteristics wherein his growth is stunted but has a high-pitched voice.

Dwarfism impacts the growth of the individual and it causes other physical problems like bowed legs or an unusually curved spine. This is because the body does not produce growth hormones that are required for the body to grow. According to NHS, there is the possibility of hereditary impact as well wherein genes also play a role in it.

The majority of the people who suffer from this disease of dwarfism are able to live a normal and healthy life like others.

Hasbulla is active on the social media platform Instagram with more than 1.7 million followers. In 2021, his follower count on Instagram peaked.

There is not much information available about Hasbullas parents identity. However, it is said that the @HasbullaHive account is operated by his brother.

Hasbulla had no fight as of now. Even though there were announcements made about different fights earlier he is yet to enter a ring or octagon. Hasbulla was present at the UFC 267.

At the event, Hasbulla and his long-time rival Abdu Rozik came face to face with each other so speculation is rife that a fight could be coming soon. However, for now, fans need to keep their fingers crossed until Hasbulla gears up for a fight.

22-year-old Woman Trapped in Body of an 8-year-old, Story of Shauna Ray – News18

If we informed you that the mind of a 22-year-old girl is trapped inside the body of an 8-year-old girl, you would consider it a part of some supernatural story. But a girl, Shauna Ray, is living in such a situation in the real world.

Shauna Ray is living in a strange and annoying situation. People do not believe her, but she is 22 years old and looks like an 8-year-old girl.

Shauna is only 3-foot 10-inch tall, an average height of an 8-year-old girl. After seeing her, people treat her like a child. Shauna shared experiences about her life by appearing on the TLC reality series and informed everyone that while she behaves like a mature person, people think of her as a child.

Shauna was diagnosed with brain cancer when she was only 6 months old and chemotherapy treatment was given to save her life. While this did save Shaunas life, her pituitary gland had such a bad effect that the production of her growth hormone decreased. This is the reason her age kept increasing, but her body did not develop accordingly.

Talking to TLC, Shauna said that she wants to act like a 22-year-old girl in general and wants people to treat her the same way. She says that she has to struggle a lot even for simple things like going to the bar, getting a tattoo and going on a blind date.

Although the story of Shauna is very distinct, something similar happened to a 34-year-old woman. Due to a head injury in her childhood, her mind was stuck in her teenage years.

In another such case, a 23-year-old girl looks half her age due to a problem in her pituitary gland. This gland produces growth hormones in our body for our overall development.

Physiology of growth hormone secretion during sleep

The temporal relation between the first few hours of sleep and the secretion of growth hormone (GH), which is present in normal persons of both sexes from early childhood until late adulthood, is reviewed. In adults the most reproducible pulse of GH secretion occurs shortly after the onset of sleep in association with the first phase of slow-wave sleep (SWS) (stages III and IV). In men approximately 70% of the GH pulses during sleep coincide with SWS, and the amount of GH secreted during these pulses correlates with the concurrent amount of SWS. Sleep-related secretion of GH appears to be primarily dependent on the release of growth hormone-releasing-hormone. Rodent and human studies have shown that growth hormone-releasing hormone injections decrease wakefulness and increase SWS. During the fourth decade of life (ages 30 to 40 years) the total amount of GH secreted over a 24-hour span decreases by two- to threefold. Similarly, the amount of SWS decreases dramatically over the same narrow age range. Because the sleep-onset GH pulse is often the major secretory output in adults, age-related decrements in sleep-related GH secretion likely play a major role in the hyposomatotropism of senescence.

Tom Bradys best throw of the night destroys Microsoft tablet – The Verge

After throwing a fourth-quarter interception to seal a 9-0 loss against the Saints on Sunday night, Tampa Bay quarterback Tom Brady managed to connect with a Microsoft Surface tablet, absolutely destroying it. The defeat was Bradys first shutout in 15 years, according to CBS Sports.

Brady joins an illustrious group of Surface abusers that include Aaron Rogers, Johnny Manziel, and former boss Bill I just cant take it anymore Belichick, to name just a few.

Surface tablets have suffered regular abuse since their introduction in the 2014 NFL season after Microsoft became the official provider of tablet-based image reviews for teams during games, replacing the black-and-white photographs that had been in use for decades. The tablets were frequently called iPads in early post-game interviews despite Microsoft paying millions to the NFL for the exclusive advertising and equipment rights. And early technical and usability issues often caused the Surface tablets to become high-speed projectiles in the hands of athletes prone to favoring human growth hormone injections over vaccines.

European wine grapes have their genetic roots in western Asia – New Scientist

We used to think that European wine grapes were cultivated locally, independently of grape domestication in western Asia, but grape genetics suggests otherwise

By Carissa Wong

Grapes used to make common European wines may have originated from grapevines that were first domesticated in the South Caucasus region of western Asia. As these domesticated grapes dispersed westwards during the Greek and Roman times, they interbred with local European wild populations, which helped the wine grapes adapt to different European climates.

The origins of grapes (Vitis vinifera) that are used in Europe and elsewhere to produce wines such as Merlot, Chardonnay and Pinot Noir have long been debated.

It has been proposed that European wine grapes arose from the cultivation of wild European populations (V. viniferasubspecies sylvestris), independently of the original domestication of grapes in western Asia around 7000 years ago.

But a genetic analysis carried out by Gabriele Di Gaspero at the Institute of Applied Genomics in Udine, Italy, and his colleagues suggests that European wine grapes actually originated from domesticated grapes (V. vinifera subspecies sativa) that were initially grown for consumption as fresh fruit in western Asia.

The team sequenced the genomes of 204 wild and cultivated grape varieties to cover the range of genetic diversity in cultivated grapes and compared how similar their genetic sequences were to one another.

This revealed that as western Asian table grapes spread westwards across the Mediterranean and further inland into Europe, they interbred with wild European grape populations that grew nearby.

The wild plants grew close to vineyards and interbred this was unintentional. But the results of the breeding created adaptive traits that were likely selected by humans intentionally, says Di Gaspero. By bringing together this genetic evidence and existing historical evidence, the introductions in southern Europe and inland likely occurred in Greek and Roman times, although we dont know more specific dates.

By modelling how the ancestry of the grapes in different regions of Europe related to aspects of the local climate such as temperature and precipitation, the team discovered that European wild grapes probably contributed traits that enabled the ancestral grape vines to adapt to different regions as they moved westwards from Asia.

The team also found evidence of the effect that domestication had on grape genetics.

In wild grape varieties, a larger seed makes a larger berry because grape seeds produce a growth hormone called ethylene. But for human consumption, a larger berry-to-seed ratio is desirable. The team found that an enzyme not found in the berries of wild varieties was present in the berries of domesticated varieties. In other plants, the enzyme is known to help berries grow in response to ethylene, which suggests it does the same in grapes.

Understanding which genes encode favourable traits in grapes can allow us grow better grape crops, says Di Gaspero.
