It's hormones.

Global multiple nucleotide or peptide sequence alignment and phylogenetic analysis

How about these hormones or resveratrol?

The cows are fed antibiotics and hormones.

He was given female hormones at age 12.

She started to take hormones at age 12.

Teenagers are often said to have raging hormones.

If animals are under stress, they can have permanently raised concentrations of stress hormones, reduced concentrations of sex hormones, and compromised immune systems.

There's no evidence that hormones or other chemicals are to blame

Smiling can help reduce the level of stress enhancing hormones like cortisol, adrenaline and dopamine, increase the level of mood enhancing hormones like endorphin and reduce overall blood pressure.

So I'm talking about thoughts and feelings and the sort of physiological things that make up our thoughts and feelings, and in my case, that's hormones. I look at hormones.

Making matters worse, the livestock are injected with large amounts of hormones and antibiotics.

Christopher's videos cover everything from the injection of hormones to recovering from a mastectomy.

If animals are under stress, they can have permanently raised concentrations of stress hormones, reduced concentrations of sex hormones, and compromised immune systems. These uncontrolled variables make the animals unsuitable subjects for scientific studies.

The pigs, cattle and goats that imported into Hong Kong, what kind of feed and growth hormones are they fed with?

Instead, we should be attacking known environmental carcinogens not just tobacco, but also radiation, sunlight, benzene, solvents, and some drugs and hormones.

He had a crush on his Chinese teacher but what with all the hormones, he had a crush on just about everyone.

Hormone therapy takes advantage of the fact that many (but not all) breast cancers have receptors for the female hormones estrogen and progesterone.

The yellow green area is the fluids of blood, which is mostly water, but it's also antibodies, sugars, hormones, that kind of thing.

For example, he learned the importance of the structural rigidity that double bonds confer on molecular structures which is relevant both to peptide bonds in proteins and the structure of nucleotides in DNA.

When proline is bound as an amide in a peptide bond, its nitrogen is not bound to any hydrogen, meaning it cannot act as a hydrogen bond donor, but can be a hydrogen bond acceptor.

Among these are thyroid hormones, which regulate the part of the brain involved in a variety of vital functions, including reproduction, sleep, thirst, eating and puberty.

These signals are usually in the form of soluble messengers such as hormones and growth factors and are detected by specific receptors on the cell surface.

The hippocampus, a key structure in the formation of memories of events and contexts, expresses receptors that enable it to respond to stress hormones in the blood.

The response is fuelled by stress hormones that flow through the body, altering every organ and biochemical function, with wide ranging effects on metabolism, growth, and reproduction.

Yet, there's no consistent body of evidence that hormones in milk or other foods, chemicals in the environment or sexual messages in the media are to blame.

Many of the chemicals under scrutiny for their effects on brain development appear to act by interfering with the function of hormones essential for healthy brain development.

Bernal's main scientific interest was initially the atomic structure of crystals, metals, and minerals, then of hormones and sterols and of some amino acids, the building blocks of proteins.

As only female birds lay eggs, medullary tissue is only found naturally in females, although males are capable of producing it when injected with female reproductive hormones like estrogen.

Many chemical mediators are involved, including cortisol and adrenalin from the adrenal glands, other hormones and neurotransmitters (such as serotonin and noradrenalin), and responses from the autonomic and immune systems.

For epidemiology (e.g. studies on vitamins, diet, or hormones in terms of their association with health outcomes in the general population), four fifths of the most prestigious findings were rapidly contradicted.

Most scientists today subscribe to a mechanistic view of the mind we're the way we are because our brains are wired up as they are our hormones are the way they are.

These features can manifest themselves in secondary sexual characteristics, such as muscle mass, hair distribution, breasts and stature primary sexual characteristics such as reproductive organs and genitalia or in chromosomal structures and hormones.

If my family, though, had been the kind of people to believe in therapy, they probably would have diagnosed me as something like gender dysmorphic and put me on hormones to stave off puberty.

He coined the term gender identity and argued that social and environmental cues how parents raised a child interacted with a child's genes and hormones to shape whether the person identified as male or female.

some parallel work going on in social psychology some people reviewed 208 different studies in which volunteers had been invited into a psychological laboratory and had their stress hormones, their responses to doing stressful tasks, measured.

An increase in sympathetic nervous system stimulation causes the heart rate to increase, both by the direct action of sympathetic nerve fibers on the heart and by causing the endocrine system to release hormones such as epinephrine (adrenaline), which have a similar effect.

Many chemical mediators are involved, including cortisol and adrenalin from the adrenal glands, other hormones and neurotransmitters (such as serotonin and noradrenalin), and responses from the autonomic and immune systems. Depression thus leads to changes in the rest of the body, owing to long term chemical imbalances in the systems that control the heart, the immune system, and metabolism.

Even with the most robust types of research for example, randomized clinical trials one of four of these results had already been found to be wrong or potentially exaggerated within a few years after publication. For epidemiology (e.g. studies on vitamins, diet, or hormones in terms of their association with health outcomes in the general population), four fifths of the most prestigious findings were rapidly contradicted.
