Stress is a normal reaction the body has when negative changes occur, resulting in physical, emotional and intellectual responses. Stress is a natural feeling of not being able to cope with specific demands and events. Stress is the feeling of being overwhelmed or unable to cope with mental or emotional pressure.
These demands can come from work, relationships, financial pressures, and other situations, but anything that poses a real or perceived challenge or threat to a person’s well-being can cause stress.
Stress can be a motivator, and it can even be essential to survival. The body’s fight-or-flight mechanism tells a person when and how to respond to danger. However, when the body becomes triggered too easily, or there are too many stressors at one time, it can undermine a person’s mental and physical health and become harmful.
The human body is designed to experience stress and react to it. When you experience changes or challenges (stressors), your body produces physical and mental responses, that is stress.
Stress responses help your body adjust to new situations. Stress can be positive, keeping us alert, motivated and ready to avoid danger. For example, if you have an important test coming up, a stress response might help your body work harder and stay awake longer. But stress becomes a problem when stressors continue without relief or periods of relaxation.
Stress can be a short-term issue or a long-term problem, depending on what changes in your life. Regularly using stress management techniques can help you avoid most physical, emotional and behavioral symptoms of stress.

For example, high blood pressure can be diagnosed and treated.
Bay Biosciences is a global leader in providing researchers with high quality, clinical grade, fully characterized human tissue samples, bio-specimens and human bio-fluid collections from cancer (tumor) tissue, cancer serum, cancer plasma cancer PBMC and human tissue samples from most other therapeutic areas and diseases.
Bay Biosciences maintains and manages it’s own bio-repository, human tissue bank (biobank) consisting of thousands of diseased samples (specimens) and from normal healthy donors available in all formats and types. Our biobank procures and stores fully consented, deidentified and institutional review boards (IRB) approved human tissue samples and matched controls.
All our human human tissue collections, human specimens and human bio-fluids are provided with detailed samples associated patient’s clinical data. This critical patient’s clinical data includes information relating to their past and current disease, treatment history, lifestyle choices, biomarkers and genetic information. Patient’s data is extremely valuable for researchers and is used to help identify new effective treatments (drug discovery & development) in oncology, other therapeutic areas and diseases. This clinical information is critical to demonstrate their impact, monitor the safety of medicines, testing & diagnostics, and generate new knowledge about the causes of disease and illness.
Bay Biosciences banks wide variety of human tissue samples and biological samples including cryogenically preserved -80°C, fresh, fresh frozen tissue samples, tumor tissue samples, FFPE’s, tissue slides, with matching human bio-fluids, whole blood and blood derived products such as serum, plasma and PBMC’s.
Bay Biosciences is a global leader in collecting and providing human tissue samples according to the researchers specified requirements and customized, tailor made collection protocols. Please contact us anytime to discuss your special research projects and customized human tissue sample requirements.
Bay Biosciences provides human tissue samples (human specimens) from diseased and normal healthy donors; including peripheral whole-blood, amniotic fluid, bronchoalveolar lavage fluid (BAL), sputum, pleural effusion, cerebrospinal fluid (CSF), serum (sera), plasma, peripheral blood mononuclear cells (PBMC’s), saliva, Buffy coat, urine, stool samples, aqueous humor, vitreous humor, kidney stones, renal calculi, nephrolithiasis, urolithiasis and other bodily fluids from most diseases including cancer. We can also procure most human bio-specimens and can do special collections and requests of human samples that are difficult to find. All our human tissue samples are procured through IRB approved clinical protocols and procedures.
In addition to the standard processing protocols Bay Biosciences can also provide human plasma, serum, PBMC bio-fluid samples using custom processing protocols, you can buy donor specific sample collections in higher volumes and specified sample aliquoting from us. Bay Biosciences also provides human samples from normal healthy donors, volunteers, for controls and clinical research, contact us Now.
