In this paper, we proposed a number rule for 3d-4f and 4f cyclic coordination cages (CCCs); that is, CCCs consisting of vertex-sharing M4(μ3-OH)4 (M = 3d transition metal or 4f lanthanide ions) units should have 3 × n metal centers (abbreviated M3n), where n represents the number of the M4(μ3-OH)4 subunits. Under this number rule we reasoned that some species of CCCs, for example, the pentadecanuclear 3d-4f wheel and the pure 4f wheels with 9 or 18 centers, should practically have existed. However, there are no such complexes reported in the literature...

A combined method, employing NMR and EPR spectroscopies, has demonstrated its strength in solving structures of protein/RNA and other types of biomolecular complexes. This method works particularly well when the large biomolecular complex consists of a limited number of rigid building blocks, such as RNA-binding protein domains (RBDs). A variety of spin labels is available for such studies, allowing for conventional as well as spectroscopically orthogonal double electron-electron resonance (DEER) measurements in EPR...

Alemtuzumab, a humanized anti-CD52 monoclonal antibody, is approved for the treatment of active relapsing-remitting multiple sclerosis (MS). Alemtuzumab induces a rapid and prolonged depletion of lymphocytes from the circulation, which results in a profound immuno-suppression status followed by an immune reconstitution phase. Secondary to reconstitution autoimmune diseases represent the most common side effect of Alemtuzumab treatment. Among them, Graves' disease (GD) is the most frequent one with an estimated prevalence ranging from 16...

Cardiovascular disease is the leading cause of death in women accounting for 1 in every 4 female deaths. Pathophysiology of ischemic heart disease in women includes epicardial coronary artery, endothelial dysfunction, coronary vasospasm, plaque erosion and spontaneous coronary artery dissection. Angina is the most common presentation of stable ischemic heart disease (SIHD) in women. Risk factors for SIHD include traditional risks such as older age, obesity (body mass index [BMI] >25 kg/m(2)), smoking, hypertension, dyslipidemia, cerebrovascular and peripheral vascular disease, sedentary lifestyle, family history of premature coronary artery disease, metabolic syndrome and diabetes mellitus, and nontraditional risk factors, such as gestational diabetes, insulin resistance/polycystic ovarian disease, pregnancy-induced hypertension, pre-eclampsia, eclampsia, menopause, mental stress and autoimmune diseases...

Purpose We investigated the possible factors for predicting the future progression to hepatocellular carcinoma (HCC) from hypovascular nodules detected in the hepatobiliary phase of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-MRI). Material and Methods A total of 91 hypovascular nodules detected by Gd-EOB-DTPA-MRI in 28 patients without any past history of treatment for HCC were retrospectively examined. The nodules were categorized into those with and without HCC progression, then comparisons were made to identify any factors possibly related to a progression to HCC in each case...

PURPOSE: Stereotactic radiosurgery (SRS) is a common treatment for intracranial meningiomas. SRS is planned on a pre-therapy gadolinium-enhanced T1-weighted MRI scan (Gd-T1w MRI) in which the meningioma contours have been delineated. Post-SRS therapy serial Gd-T1w MRI scans are then acquired for longitudinal treatment evaluation. Accurate tumor volume change quantification is required for treatment efficacy evaluation and for treatment continuation. METHOD: We present a new algorithm for the automatic segmentation and volumetric assessment of meningioma in post-therapy Gd-T1w MRI scans...

We describe the case of an African woman who was diagnosed with ketosis-prone diabetes with diabetes-associated autoantibodies, after being admitted for diabetic ketoacidosis (DKA) precipitated by her first presentation of systemic lupus erythematosus (SLE). She had a seven-year history of recurrent gestational diabetes (GDM) not requiring insulin therapy, with return to normoglycaemia after each pregnancy. This might have suggested that she had now developed type 2 diabetes (T2D). However, the diagnosis of SLE prompted testing for an autoimmune aetiology for the diabetes, and she was found to have a very high titre of GAD antibodies...

There are three major therapeutic options for the treatment of Graves' disease (GD): antithyroid drugs (ATDs), thyroidectomy, and radio-iodine (RAI) therapy. ATDs are the initial treatment option for children. However, some pediatric GD patients who are initially treated with ATDs require other type of treatments later on. We reviewed the medical records of childhood-onset GD cases retrospectively to report the clinical course of patients who received either surgery or RAI therapy subsequent to treatment with ATDs...

BACKGROUND A case report of urethral diverticulum complicating pregnancy is presented. The diagnosis and management are challenging because of the rare nature of this condition, the varied presentations and differential diagnoses, and the possibility of misdiagnosis. CASE REPORT A 25-year-old primigravida with scheduled induction of labor at 39 weeks gestation due to gestational diabetes mellitus presented for a routine antenatal appointment at 38 weeks and four days. On digital cervical examination, she was found to have a large semi-solid anterior vaginal mass, shown by trans-vaginal ultrasound to have a nearly solid appearance of a 5×7 cm mass with septation...

INTRODUCTION: Gestational diabetes is one of the diseases associated with pregnancy with higher rate of complications. Despite being a transitory condition, short and long term complications related to gestational diabetes have been described. There is scientific evidence to say that good metabolic control decreases perinatal complications. In 2011, new criteria was proposed for its diagnosis, which made possible its diagnosis during the 1st trimester of pregnancy. The aim of this study is to compare neonatal morbidity in two groups of women with gestational diabetes diagnosis before and after the latest Portuguese guidelines for diabetes and pregnancy were published (February 2011)...
