Exposure to secondhand smoke from burning tobacco products causes premature death and disease, including coronary heart disease, stroke, and lung cancer among nonsmoking adults and sudden infant death syndrome, acute respiratory infections, middle ear disease, exacerbated asthma, respiratory symptoms, and decreased lung function in children (1,2). The U.S. Surgeon General has concluded that there is no risk-free level of exposure to secondhand smoke (1). Previous CDC reports on airport smoke-free policies found that most large-hub airports in the United States prohibit smoking (3); however, the extent of smoke-free policies at airports globally has not been assessed...

BACKGROUND: Overweight and obesity are associated with an increased risk of developing many types of cancer, including breast cancer. Moreover, increased body mass index (BMI) seems to be associated with a worse prognosis in patients with HER2-positive early breast cancer. However, little is known about the impact of BMI on the clinical outcomes of HER2-positive metastatic breast cancer (MBC). METHODS: This was a multicenter retrospective cohort study including 329 consecutive patients with HER2-positive MBC treated with first-line trastuzumab-based regimens...

Of the 8.8 million deaths from cancer in 2015, per the World Health Organization, lung cancer was the most common cause of death (1.69 million). With the introduction of low-dose CT for lung cancer screening and emergence of precision medicine for often-fatal lung cancer, there is a need for deep access to critical information, i.e. radiomics, not possible with conventional subjective interpretation of CT images. Quantitative image analyses for radiomics have been applied in lung cancers to determine their spatial complexity, genomic composition, viability or aggressiveness, and responses to targeted therapies...

Cancer, the main cause of human deaths in the modern world is a group of diseases. Anticancer drug discovery is a challenge for scientists because of involvement of multiple survival pathways of cancer cells. An extensive study on the regulation of each step of these pathways may help find a potential cancer target. Up-regulated HIF-1 expression and altered metabolic pathways are two classical characteristics of cancer. Oxygen-dependent (through pVHL, PHDs, calcium-mediated) and independent (through growth factor signaling pathway, mdm2 pathway, HSP90) regulation of HIF-1α leads to angiogenesis, metastasis, and cell survival...

Pulmonary tuberculosis infects one-third of world's population and is responsible for the high mortality and morbidity in developing countries. The presence of a high number of macrophages and lymphocytes in active tuberculosis granulomas is associated with high uptake of (18)F-fluoro-2-deoxy-d-glucose on PET imaging mimicking lung cancer. In many cases, radiological features of pulmonary tuberculosis are undistinguishable from lung cancer, which makes the diagnosis difficult. Clinical history and computed tomographic (CT) findings on a hybrid PET/CT are as important as findings on a PET in the diagnosis of lung cancer...

Colorectal cancer is one of the most prevalent cancers with high mortality in the world. MicroRNAs are a class of small non-coding RNAs that regulate gene expression through targeting mRNAs. MicroRNAs involve in many biological and pathological processes such as cell growth, differentiation, apoptosis. etc. Dysregulation of miRNAs expression patterns have been reported in many tumors including Colorectal Cancer. Various studies indicate that miRNAs can be utilized as diagnostic and prognostic biomarkers for evaluation of tumor initiation, development, invasion, metastasis and response to chemotherapeutic drugs...

Gastric cancer is one of the most common cancers in the world and glycolysis is a major feature of gastric cancer. MicroRNAs (miRNAs) involve in gastric cancer cell proliferation, glycolysis and other cellular processes. MiR-139-5p is reported as a tumor suppressor in cancers, however, the role of miR-139-5p including glycolytic metabolism is unclear in gastric cancer. So, the purpose of the present study is to elucidate the underlying mechanism in gastric cancer metabolism mediated by miR-139-5p. Our results revealed that miR-139-5p inhibited glycolysis by regulating AMP-activated, alpha 1 catalytic subunit (PRKAA1) expression in gastric cancer cells...

Helicobacter Pylori is a gram negative rod shaped microaerophilic bacterium that colonizes the stomach of approximately half the world's population. Infection with c may cause chronic gastritis which via a quite well described process known as Correas cascade can progress through sequential development of atrophic gastritis, intestinal metaplasia and dysplasia to gastric cancer. H. pylori is currently the only bacterium that is classified as a class 1 carcinogen by the WHO, although the exact mechanisms by which this bacterium contributes to gastric carcinogenesis are still poorly understood...

Cancer treatment is one of the main challenges that face the scientific centers all over the world. The cancer incidence percentage increases year after year. The most used treatment for cancer is chemotherapy which is an application of systemic cytotoxic drug inside the patient. There are two main problems in chemotherapy that the cytotoxic drug is given systematically and cannot be localized in the tumor region in most cases that lead to killing the cancer cells as well as normal cells; and that cause the chemotherapy side effects like anemia, decrease in all blood cells count and platelets, nausea, vomiting, diarrhea, hair and nails loss and may cause a kind of blood toxicity...
