Cracking the Enigma of Fatty Liver Disease

Nonalcoholic fatty liver disease (NAFLD) affects one out of four people in the world, making it the most prevalent of all liver diseases and a major public health problem. The disease is defined by abnormally increased fat deposition in liver cells, which can progress with the addition of inflammation and cell damage to nonalcoholic steatohepatitis (NASH), leading to progressive stages of fibrosis and, finally, cirrhosis. Early NASH is characterized by fat and inflammation associated with minimal amounts of fibrosis, and late NASH is associated with advanced fibrosis or cirrhosis. NAFLD is most closely associated with obesity and diabetes, although there are likely other genetic, nutritional, and environmental factors involved in the pathogenesis.

Although there are no approved pharmacologic treatments for NAFLD, NASH, or cirrhosis, there are over a dozen different companies researching possible treatments. However, the development of drug therapies for the NAFLD spectrum of disease is hampered by a number of challenges:
  • the chronic nature of the disorder and ultimately low morbidity and mortality,
  • the impact of weight loss on the disease,
  • a complex and poorly defined pathophysiology,
  • the lack of easily administered diagnostic testing, and
  • the evolving status of regulatory endpoints.

The results of multiple clinical trials over the next few years will clarify potential therapies and target
pathways.  © Sebastian Kaulitzki/Fotolia]

If You Are In Danger Of BREAST CANCER, Your Body Will Give You These 5 Signs!

Invasive breast cancer affects 1 in 8 women in the US only. It’s the type of cancer with the highest incidence among women. According to the American Cancer Society, by the end of 2016, 246,660 new cases of invasive breast cancer will be diagnosed in America, 40,450 of which will be terminal.
Detecting the cancer early significantly increases the chances of successful treatment. Knowing the early signs and symptoms of invasive breast cancer can help you detect it in its early stages.
  1. FATIGUE
Fatigue is a common symptom in many types of cancer, including breast cancer. The thing is this type of fatigue cannot be alleviated by sleep or rest. Cancer-related fatigue is not caused by physical strain and is often accompanied by other symptoms such as pain, sleep disturbance and depression. This fatigue is caused by an imbalance of chemicals in the body the cancer creates, according to scientists.




Heatwaves, Cold Snaps May Raise Preterm Birth Risk

Being pregnant during a heatwave is far from the most pleasant scenario for a woman, but new research finds such extreme temperatures may do more than make expectant mothers uncomfortable; they could increase the risk of preterm birth.

In a study published in the journal Environmental Health Perspectives, researchers from the National Institutes of Health (NIH) found that exposure to extreme cold or intense heat during pregnancy increased women's preterm birth risk by up to a fifth.

According to the Centers for Disease Control and Prevention (CDC), in 2014, around 1 in 10 infants in the United States were born preterm - defined as the birth of a baby before 37 weeks of pregnancy.

Preterm birth is the leading cause of infant death in the U.S., and it is also a primary cause of long-term disabilities and neurological disorders, such as cerebral palsy and developmental delay.


Researchers say exposure to extreme heat or cold during pregnancy may increase the risk of preterm
birth.

From Krebs to Clinic: Glutamine Metabolism to Cancer Therapy

The resurgence of research into cancer metabolism has recently broadened interests beyond glucose and the Warburg effect to other nutrients, including glutamine. Because oncogenic alterations of metabolism render cancer cells addicted to nutrients, pathways involved in glycolysis or glutaminolysis could be exploited for therapeutic purposes. In this Review, we provide an updated overview of glutamine metabolism and its involvement in tumorigenesis in vitro and in vivo, and explore the recent potential applications of basic science discoveries in the clinical setting.

  • Cancer cells show increased consumption of and dependence on glutamine.
  • Glutamine metabolism fuels the tricarboxylic acid (TCA) cycle, nucleotide and fatty acid biosynthesis, and redox balance in cancer cells.
  • Glutamine activates mTOR signaling, suppresses endoplasmic reticulum stress and promotes protein synthesis.

Zika Virus — Reigniting The TORCH

The recent association between Zika virus (ZIKV) infection during pregnancy and fetal microcephaly has led to a renewed interest in the mechanisms by which vertically transmitted microorganisms reach the fetus and cause congenital disease. In this Opinion article, we provide an overview of the structure and cellular composition of the human placenta and of the mechanisms by which traditional 'TORCH' pathogens (Toxoplasma gondii, other, rubella virus, cytomegalovirus and herpes simplex virus) access the fetal compartment. Based on our current understanding of ZIKV pathogenesis and the developmental defects that are caused by fetal ZIKV infection, ZIKV should be considered a TORCH pathogen and future research and public health measures should be planned and implemented accordingly.

Zika virus (ZIKV), a member of the Flaviviridae family of RNA viruses, was first isolated in the Zika forest in Uganda in 1947.

Have You Woken Up At Night And Were Unable To Move And Felt Paralyzed?

The average person sleeps for around eight hours a day. Over a lifetime this amounts to spending about one third of life asleep. It’s common knowledge that a good nights rest is vitally important for maintaining health and balance, both mentally and physically.

However, for some people a good night’s sleep is hard to come by, or it ends up being ruined, by a strange phenomenon that is called sleep paralysis.

Scientists Have Shown What Our Emotions Actually Look Like

Our bodies experience a range of physical sensations depending on whether we feel joy, sadness, or fear. Scientists from Finland recently discovered through precisely which parts of our body we experience a range of emotions. They represented this visually by showing the strongest emotions and sensations in yellow and red. Those areas of the body where their test subjects experienced a weak emotion were represented in a dark or light blue color.

We at Bright Side found it truly fascinating to learn what our emotions and their corresponding physical sensations ’look’ like in our bodies.

Study Finds Potential New Biomarker For Cancer Patient Prognosis

To treat or not to treat? That is the question researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) hope to answer with a new advance that could help doctors and their cancer patients decide if a particular therapy would be worth pursuing.

Berkeley Lab researchers identified 14 genes regulating genome integrity that were consistently overexpressed in a wide variety of cancers. They then created a scoring system based upon the degree of gene overexpression. For several major types of cancer, including breast and lung cancers, the higher the score, the worse the prognosis. Perhaps more importantly, scores could accurately predict patient response to specific cancer treatments.

The researchers said the findings, to be published Wednesday, Aug. 31, in the journal Nature Communications, could lead to a new biomarker for the early stages of tumor development. The information obtained could help reduce the use of cancer treatments that have a low probability of helping.

Early Signs That Cancer Is Growing In Your Body

There’s an important rule about cancer, one of the leading causes of death in the world, and it’s the sooner it’s detected, the higher chances of successful treatment.

Because of that fact, don’t rely on routine tests alone to protect you from cancer. It’s just as important to listen to your body and notice anything that’s different, odd, or unexplainable.

Here are some early signs that are commonly overlooked:

1.Wheezing or shortness of breath
One of the first signs many lung cancer patients remember noticing is the inability to catch their breath.

2.Chronic cough or chest pain
Several types of cancer, including leukemia and lung tumors, can cause symptoms that mimic a bad cough or bronchitis. Some lung cancer patients report chest pain that extends up into the shoulder or down the arm.



All You Need to Know About the Glucose Tolerance Test

Most of the food people eat is turned directly into glucose when digested, and the body uses it as energy. The pancreas is responsible for making the hormone insulin which helps to get glucose into the cells of the body.

Diabetes is a long-term disease that occurs due to the pancreas not producing enough insulin or the body being unable to use the insulin it produces effectively.

The body is unable to process food properly to use for energy. Glucose builds up in the blood, which can lead to severe health problems.

There are two main types of diabetes. Type 1 diabetes is usually diagnosed in children and young adults and is also known as juvenile diabetes. With type 1 diabetes the body does not produce insulin. 


A glucose tolerance test can be used to screen for type 2 diabetes. Gestational diabetes can occur in
pregnant woman who have never had diabetes but have high blood glucose levels. During the
glucose test, some people may experience nausea, lightheadedness, shortness of breath, and sweating.
