Four out of ten Brits may naturally show fewer flu symptoms

ConclusionA study of 1,414 unvaccinated people showed those with T cells targeting virus nucleoprotein still got infected by flu, but had fewer symptoms. The logic is that people with fewer symptoms are less likely to spread the virus through coughs and sneezes, which may slow the spread of both seasonal and pandemic flu strains.This is plausible, but was not directly tested in this study, so we don't know if it's true in real life. The research team suggested vaccines that boost T cell numbers might be worth exploring, as an alternative to those that try to stop virus infection altogether. An added potential benefit of their finding was that lessened symptoms in one virus strain showed similar signs in another. That said, only two virus types were tested, so we don't know whether this "cross-reactivity" is more widespread.The findings suggest around 43% of people had some form of this natural immunity, but it's not clear if this is across a broad range of flu viruses or just a couple.The study is encouraging, but is in its early stages of understanding, raising as many questions as it answers. For example: Is it possible to boost this natural symptom immunity in those that have it? How common is this natural immunity in the public? Is it possible to transfer this symptom immunity to those that don’t have it? How useful is this at preventing new cases of flu or deaths from flu? If you are particularly vulnerable to the effects of a flu infection due to ...

Authors: Harada K, Yasuda M, Hasegawa K, Yamazaki Y, Sasano H, Otsuka F Abstract Adrenocortical carcinoma (ACC) is a rare malignancy arising from adrenocortical parenchymal cells. Myxoid ACC is one of the newly identified, rare, but important histological variants of ACC, characterized by the presence of abundant extracellular Alcian Blue-positive myxoid material. Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant cancer predisposition syndrome, and the incidence of ACC in MEN1 patients has been reported to be between 1.4% and 6%. Here, we report the case of a 68-year-old Japanese woman harboring t...

This study aimed to investigate if hyperinsulinemia and/or insulin resistance was correlated with the occurrence of papillary thyroid cancer (PTC) in a group of Chinese patients. 258 inpatients were included in the study. According to the postoperative pathology results, all subjects were divided into PTC (n = 153) and control groups (with benign thyroid nodules, n = 105). Body mass index (BMI), fasting glucose, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), thyroid-stimulating hormone (TSH), FT4, FT3, thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), serum uric acid (UA), ...

Authors: Procaccio L, Bergamo F, Manai C, Di Antonio V, Fassan M, Zagonel V, Lonardi S, Loupakis F Abstract Introduction: Lung metastases occur in 10-20% of patients with colorectal cancer (CRC). Most of them are treated with palliative intent and have a poor prognosis. Pulmonary metastasectomy may be a curative option for carefully selected patients with 5-year survival rates ranging from 25% to 60%. However, up to 70% of patients develop recurrence after pulmonary metastasectomy. Therefore, the identification of prognostic factors is essential in CRC patients with resectable lung metastases. Areas covered: This r...

Authors: Snijder J, Peraza J, Padilla M, Capaccione K, Salvatore MM Abstract Introduction: Idiopathic pulmonary fibrosis (IPF) is a relentless form of fibrotic lung disease with a median survival of approximately 3 years after diagnosis and a mortality rate that surpasses that of many types of cancer. The pathophysiology of IPF is complex as there are likely different stages of disease occurring simultaneously in the lung. Areas covered: Some scientists consider IPF as primarily an epithelial driven disease in which dysfunctional surfactant-producing cells take an etiological precedent. Others focus on the augmente...

This study involved patients from the North-East Indian population, where the numbers of reported cases are increasing rapidly and alarmingly. Oxidative stress, based on 8-OH-dG levels, was found to be significantly higher in gallbladder anomalies (cholelithiasis [CL] and cholecystitis [CS]) and GBC at the plasma and DNA level, and was associated with GBC severity. The expressions of key BER pathway genes were downregulated in gallbladder anomalies and GBC compared to controls, and in GBC compared to both non-neoplastic controls and gallbladder anomalies. Expression of XRCC1 and hOGG1 was significantly associated with both...

Activation of Ras-ERK1/2 has been testified to be linked to the progression of diverse cancers. Nonetheless, whether Ras-ERK1/2-tumorigenic pathway is mediated by epigenetic factors remains indistinct. The purpose of the research attempted to disclose the functions of H2BK5ac in Ras-ERK1/2-evoked CRC cell phenotypes.Materials and methodsWestern blot assay was implemented for exp...
