Twisting moduli for GL(2)
We prove various converse theorems for automorphic forms on \Gamma_0(N), each assuming fewer twisted functional equations than the last. We show that no twisting at all is needed for holomorphic modular forms in the case that N\in{18,20,24} - these integers are the smallest multiples of 4 or 9 not covered by earlier work of ConreyâFarmer. This development is a consequence of finding generating sets for \Gamma_0(N) such that each generator can be written as a product of special matrices. As for real-analytic Maass forms of even (resp. odd) weight we prove the analogous statement for 1\leq N\leq 12, 14\leq N\leq18 and N\in{16,18} (resp. 1\leq N\leq 12, 14\leq N\leq 18 and N\in{20,23,24})
Native Ambient Mass Spectrometry of an Intact Membrane Protein Assembly and Soluble Protein Assemblies Directly from Lens Tissue
Membrane proteins constitute around twoâthirds of therapeutic targets but present a significant challenge for structural analysis due to their low abundance and solubility. Existing methods for structural analysis rely on overâexpression and/or purification of the membrane protein, thus removing any links back to actual physiological environment. Here, we demonstrate mass spectrometry analysis of an intact oligomeric membrane protein directly from tissue. Aquaporinâ0 exists as a 113â
kDa tetramer, with each subunit featuring six transmembrane helices. We report the characterisation of the intact assembly directly from a section of sheep eye lens without sample preâtreatment. Protein identity was confirmed by mass measurement of the tetramer and subunits, together with topâdown mass spectrometry, and the spatial distribution was determined by mass spectrometry imaging. Our approach allows simultaneous analysis of soluble protein assemblies in the tissue
Type 1 diabetes in adults: supporting self management
Clinical Review Type 1 diabetes in adults: supporting self management BMJ 2016; 352 doi: http://dx.doi.org/10.1136/bmj.i998 (Published 10 March 2016) Cite this as: BMJ 2016;352:i998 Article Related content Metrics Responses Monika Reddy, specialist registrar, diabetes and endocrinology1 2, Sian Rilstone, diabetes specialist dietitian2, Philippa Cooper, has type 1 diabetes3, Nick S Oliver, consultant diabetologist1 2 Author affiliations 1Department of Diabetes, Endocrinology and Metabolism, Imperial College London, St Maryâs Hospital Campus, London W2 1PG, UK 2Diabetes and Endocrinology, Imperial Healthcare NHS Trust, London 3London Correspondence to: N S Oliver [email protected] What you need to know Glucose concentrations in type 1 diabetes are affected by multiple interacting and independent complex factors Structured education programmes support effective self management and should be available to everyone with an established diagnosis of type 1 diabetes Long term self-management of type 1 diabetes is challenging and requires ongoing support from an expert multidisciplinary team Insulin dose adjustment involves carbohydrate estimation and mental arithmetic, which can be supported with technology Healthcare professionals should be alert to signs of depression or distress in people with type 1 diabetes, and access to psychosocial support is critical Type 1 diabetes affects 300â000 people in the United Kingdom.1 2 Despite regular specialist multidisciplinary input, responsibility for glucose monitoring and insulin administration is devolved to the person with diabetes, or their care giver. Empowering effective self management of type 1 diabetes is critical to achieve HbA1c targets, minimise hypoglycaemia and optimise quality of life. Structured education programmes for diabetes self management should be offered to everyone with type 1 diabetes. It is important for healthcare providers to understand what structured education involves before referral. This review examines the meaning and evidence for self management, and provides advice on how general physicians and non-specialists can support and enable people with type 1 diabetes to self manage their condition
