TL;DR: It is shown that phylogenetic ct DNA profiling tracks the subclonal nature of lung cancer relapse and metastasis, providing a new approach for ctDNA-driven therapeutic studies.
Abstract: The early detection of relapse following primary surgery for non-small-cell lung cancer and the characterization of emerging subclones, which seed metastatic sites, might offer new therapeutic approaches for limiting tumour recurrence. The ability to track the evolutionary dynamics of early-stage lung cancer non-invasively in circulating tumour DNA (ctDNA) has not yet been demonstrated. Here we use a tumour-specific phylogenetic approach to profile the ctDNA of the first 100 TRACERx (Tracking Non-Small-Cell Lung Cancer Evolution Through Therapy (Rx)) study participants, including one patient who was also recruited to the PEACE (Posthumous Evaluation of Advanced Cancer Environment) post-mortem study. We identify independent predictors of ctDNA release and analyse the tumour-volume detection limit. Through blinded profiling of postoperative plasma, we observe evidence of adjuvant chemotherapy resistance and identify patients who are very likely to experience recurrence of their lung cancer. Finally, we show that phylogenetic ctDNA profiling tracks the subclonal nature of lung cancer relapse and metastasis, providing a new approach for ctDNA-driven therapeutic studies.
TL;DR: Lack of reproducibility, a feature of previous methods of measuring the susceptibility of red cells to exogenous peroxide, could be overcome by (i) catalase inhibition, (ii) attention to the non‐linear relation between packed‐cell volume and MDA formation, and (iii) elimination of potentially misleading coloured complexes on spectroscopy.
Abstract: Summary. Malonyldialdehyde (MDA) formation, a measure of polyunsaturated fat autoxidation, was estimated in normal human red cells incubated in vitro. Exposure to oxygen under a variety of conditions did not induce autoxidation. Exposure to hydrogen peroxide was either by the addition of a hydrogen peroxide solution or by incubation in an atmosphere saturated with hydrogen peroxide vapour. A pattern of MDA formation was established with both methods. Lack of reproducibility, a feature of previous methods of measuring the susceptibility of red cells to exogenous peroxide, could be overcome by (i) catalase inhibition, (ii) attention to the non-linear relation between packed-cell volume and MDA formation, and (iii) elimination of potentially misleading coloured complexes on spectroscopy. A number of recognized antioxidants inhibited peroxide-induced MDA formation. Inhibition was proportional to the logarithm of the antioxidant concentration. Under certain conditions pre-incubation with nucleosides and with lecithin protected the cells against autoxidation on subsequent exposure to peroxide. Peroxide-induced cell autoxidation was also influenced by plasma, bovine albumin, and ascorbic acid. Haemolysis was an invariable consequence of autoxidation. Similarities and dissimilarities between autoxidation and antioxidation in free lipid emulsions and in organized biological structures were examined and discussed in the light of the experimental findings.
TL;DR: In this article, the relation between urinary albumin excretion rate (AER) and vascular disease was studied in 187 subjects aged over 40 selected from 1084 cases attending a diabetic screening project.
Abstract: The relation between urinary albumin excretion rate (AER) and vascular disease was studied in 187 subjects aged over 40 selected from 1084 cases attending a diabetic screening project. AER exceeded 20 micrograms/min in 3 of 13 newly diagnosed diabetic subjects (23%) and 16 of 171 non-diabetic subjects (9.4%). There was a weak relation between AER and both systolic and diastolic blood pressures. Coronary heart disease was found in 54 of 164 (32.9%) subjects with AER of 20 micrograms/min or less and in 14 of 19 (74%) with AER above this. Peripheral vascular disease was present in 16 of 165 (9.7%) subjects with AER of 20 micrograms/min or less and 8 of 18 (44%) with a high AER. Logistic regression, including diabetes, impaired glucose tolerance, systolic and diastolic blood pressures, smoking, age, sex, ethnic origin, and body mass index, demonstrated the independence of this relation between AER above 20 micrograms/min and coronary heart disease (odds ratio [OR] 6.38, 95% confidence interval 1.91-21.4) and peripheral vascular disease (OR 7.72, 2.14-27.8). After a mean of 3.6 (SD 0.19) years, 167 subjects (89.3%) were traced. There had been 9 deaths, 3 (2.0%) among 149 subjects with normal AER and 6 (33%) among 18 microalbuminuric subjects (OR 24.33, 5.40-109.7).

TL;DR: It is demonstrated that mutations in ATP6B1, encoding the B-subunit of the apical proton pump mediating distal nephron acid secretion, cause distal renal tubular acidosis, a condition characterized by impaired renal acid secretion resulting in metabolic acidosis.
Abstract: H+-ATPases are ubiquitous in nature; V-ATPases pump protons against an electrochemical gradient, whereas F-ATPases reverse the process, synthesizing ATP. We demonstrate here that mutations in ATP6B1, encoding the B-subunit of the apical proton pump mediating distal nephron acid secretion, cause distal renal tubular acidosis, a condition characterized by impaired renal acid secretion resulting in metabolic acidosis. Patients with ATP6B1 mutations also have sensorineural hearing loss; consistent with this finding, we demonstrate expression of ATP6B1 in cochlea and endolymphatic sac. Our data, together with the known requirement for active proton secretion to maintain proper endolymph pH, implicate ATP6B1 in endolymph pH homeostasis and in normal auditory function. ATP6B1 is the first member of the H+-ATPase gene family in which mutations are shown to cause human disease.
TL;DR: In this paper, the authors provide an update on the characterization of the Ki67 protein, its function and its use as a prognostic or diagnostic tool, as well as the number of papers published featuring this antibody has increased 10-fold from 338 to 3489.
Abstract: This article updates our previous review of Ki67 published in Histopathology 10 years ago. In this period the numbers of papers published featuring this antibody has increased 10-fold from 338 to 3489 indicating the considerable enthusiasm with which this antibody has been studied. This review attempts to provide an update on the characterization of the Ki67 protein, its function and its use as a prognostic or diagnostic tool.
