Alzheimer's disease (AD) is one of the most common neurodegenerative diseases. Its major pathological hallmarks, neurofibrillary tangles (NFT), and amyloid-β plaques can result from dysfunctional insulin signaling. Insulin is an important growth factor that regulates cell growth, energy utilization, mitochondrial function, autophagy, oxidative stress, synaptic plasticity, and cognitive function. CX5461 Insulin and its downstream signaling molecules are located majorly in the regions of cortex and hippocampus. The major molecules involved in impaired insulin signaling include IRS, PI3K, Akt, and GSK-3β. Activation or inactivation of these major molecules through increased or decreased phosphorylation plays a role in insulin signaling abnormalities or insulin resistance. Insulin resistance, therefore, is considered as a major culprit in generating the hallmarks of AD arising from neuroinflammation and oxidative stress, etc. Moreover, caspases, Nrf2, and NF-κB influence this pathway in an indirect way. Various studies also suggest a strong link between Diabetes Mellitus and AD due to the impairment of insulin signaling pathway. Moreover, studies also depict a strong correlation of other neurodegenerative diseases such as Parkinson's disease and Huntington's disease with insulin resistance. Hence this review will provide an insight into the role of insulin signaling pathway and related molecules as therapeutic targets in AD and other neurodegenerative diseases. Recent advances have revealed that lncRNAs play important roles in tumorigenesis. However, only a small number of functional lncRNAs have been well characterized, particularly in colorectal cancer. Therefore, more extensive studies are needed to identify and characterize these lncRNAs to better understand cancer progression. In the present study, using available RNA-seq data, we found that LINC02381 (NR_026656.1) differentially expresses in CRC tissues compared to normal pairs. Consistently, RT-qPCR results showed that LINC02381 was down regulated in CRC tissues and also in different cancerous cell lines. CRC cells treatment with de-methylating and chemotherapy agents indicated that DNA methylation of LINC02381 may be responsible for the transcriptional silencing of LINC02381 in colorectal cancer cells. Then, the functional changes of the cells in response to LINC02381 alteration were assessed and the data indicated that LINC02381 up-regulation suppressed cell viability and proliferation while increasing the apoptosis in CRC-originated cell lines. Mechanistically, LINC02381 overexpression was increased PTEN protein levels but decreased phospho-Akt levels. Finally, we proposed a hypothesized model for PI3K signaling regulation by LINC02381. Altogether, the result of this study suggests that LINC02381 might have suppressive effects on human colorectal cancer tumorigenesis partly by regulating PI3K signaling pathway. BACKGROUND Idiopathic pulmonary fibrosis (IPF) causes progressive dyspnea, hypoxemia and death within a few years. Little is known about the effect of air pollution on disease exacerbations. METHODS Hospital admissions for IPF are coded J84.1 by the International Classification of Disease, 10th Revision. Using ambient air pollution and climate data from seven air monitoring stations distributed in the seven urban centres in Santiago Chile, along with daily patient hospitalization data from 2001 to 2012, a linear association between daily ambient air pollution and daily J84.1 hospital admissions was tested using generalized linear models. RESULTS Average pollutant levels for all regions were as follows carbon monoxide (CO) was 0.96 ppm, ozone (O3) was 64 ppb, nitrogen dioxide (NO2) was 43 ppb, sulphur dioxide (SO2) was 9 ppb, particulate matter less then 2.5 μm in diameter (PM2.5) was 29μg/m3 and particulate matter less then 10 μm in diameter (PM10) was 67μg/m3. For the combined Santiago area, relative risk estimates of J84.1 hospitalizations for all pollutants (except ozone), adjusted for age, sex and weather were statistically significant. In the two-pollutant models, the significance of NO2 and PM10 persisted despite adjustments for each of the other measured pollutants. CONCLUSION Our findings suggest that acute increases in air pollution are a risk factor for hospitalization of patients with a primary diagnosis of IPF. BACKGROUND The evidence for the diagnosis and management of cough due to acute bronchitis in immunocompetent adult outpatients was reviewed as an update to the 2006 American College of Chest Physicians (ACCP) Evidence-Based Clinical Practice Guideline Cough due to Acute Bronchitis. METHODS Acute bronchitis was defined as an acute lower respiratory tract infection manifested predominantly by cough with or without sputum production, lasting no more than 3 weeks with no clinical or any recent radiographic evidence to suggest an alternative explanation. Two clinical PICO (Population, Intervention, Comparison, Outcome) questions were addressed by systematic review in July 2017 firstly, the role of investigations beyond the clinical assessment of patients presenting with suspected acute bronchitis; and secondly, the efficacy and safety of prescribing medication for cough in acute bronchitis. An updated search was undertaken in May 2018. RESULTS No eligible studies relevant to the first question were identified. For the second question, only one relevant study met eligibility criteria. This study found no difference in number of days with cough between patients treated with an antibiotic or an oral non-steroidal anti-inflammatory agent compared with placebo. Clinical suggestions and research recommendations were made based on the consensus opinion of the CHEST Expert Cough Panel. CONCLUSION The panelists suggested that no routine investigations be ordered and no routine medications be prescribed in immunocompetent adult outpatients first presenting with cough due to suspected acute bronchitis, until such investigations and treatments have been shown to be safe and effective at making cough less severe or resolve sooner. If the cough due to suspected acute bronchitis persists or worsens, a reassessment and consideration of targeted investigations should be considered.
