BACKGROUND: Acute vision loss in the post-partum period can occur due to many reasons. Eclampsia, posterior reversible encephalopathy syndrome (PRES), pituitary apoplexy, and central serous retinopathy are some of the important causes. Cryptococcal meningitis as a cause of acute vision loss in the post-partum period has not been mentioned in literature. CASE PRESENTATION: A 25-year-old female presented to us with acute bilateral complete vision loss in the post-partum period...

Posterior reversible encephalopathy syndrome (PRES) is a rare clinical and radiological phenomenon is encountered in children compared to adults. In our center, a 5-yearold boy with steroid-dependent nephrotic syndrome (SDNS) presented with headache and blurring of vision during relapse after a long course of immunosuppressive therapy. Evaluation by computed tomography scan of the brain showed that the child had hypodense areas throughout the occipital region of the brain. All signs of PRES, except papilledema, resolved after seven days of supportive treatment evidenced by subsequent radiological evaluation...

The wall-loosening actions of β-expansins are known primarily from studies of EXPB1 extracted from maize pollen. EXPB1 selectively loosens cell walls (CWs) of grasses, but its specific binding target is unknown. We characterized EXPB1 binding to sequentially extracted maize CWs, finding that the protein primarily binds glucuronoarabinoxylan (GAX), the major matrix polysaccharide in grass CWs. This binding is strongly reduced by salts, indicating that it is predominantly electrostatic in nature. For direct molecular evidence of EXPB1 binding, we conducted solid-state NMR experiments using paramagnetic relaxation enhancement (PRE), which is sensitive to distances between unpaired electrons and nuclei...

Posterior reversible encephalopathy syndrome (PRES) has been described in the context of uncontrolled hypertension, eclampsia, renal disease and autoimmune conditions, or in patients treated with chemotherapy or immunosuppressive agents. In contrast, we report the occurrence of PRES in a patient with untreated metastatic transitional cell carcinoma. The case emphasizes important diagnostic challenges associated with atypical presentations without "typical" risk factors and the limitations of common diagnostic imaging modalities...

In the era of combination therapy for human immunodeficiency virus (HIV), liver disease including hepatocellular carcinoma (HCC), are the major causes of death for patients co-infected with hepatitis B virus (HBV) and HIV. However, the mechanisms remain obscure. We aimed to determine whether HCC-related HBV mutations including 1762T/1764A double mutation and pre-S deletions occur more frequently in HBV/HIV co-infected individuals compared to HBV mono-infected individuals. In this study, the basic core promoter (BCP) and the preS/S regions of HBV isolated from 61 pairs of HBV/HIV co-infected and HBV mono-infected participants were analyzed...

BACKGROUND: Posterior reversible encephalopathy syndrome (PRES) is an acute neurotoxic syndrome that, although characteristically reversible, can result in long-term disability. Our aim was to identify the clinical and radiological factors that are unique to children with PRES compared with adults with the syndrome in a single center. METHODS: We retrospectively reviewed the clinical and radiological records of all patients with PRES admitted at a tertiary care medical center from 2007 to 2014...

Hypertension is a major public health problem affecting about 30% of the adult population and is associated with an increased risk of developing metabolic and cardiovascular disease. Recent reports have shown that the T-cadherin receptor characteristically expressed on endothelial and vascular smooth muscle cells is involved in hypertension. The aim of the present study was to evaluate the role of cadherin-13 (CDH13) gene polymorphisms as susceptibility markers for hypertension in Mexican population. Six CDH13 polymorphisms (rs11646213, rs11646411, rs6563943, rs3096277, rs3784990 and rs254340) were genotyped by 5' exonuclease TaqMan assays in a group of 644 hypertensive and 765 non-hypertensive individuals...

Posterior reversible encephalopathy syndrome (PRES) is an acute neurological syndrome that requires prompt, aggressive management to improve outcomes. Our aim was to identify factors that would necessitate care in the intensive care unit (ICU) in patients with PRES and the outcomes on discharge following ICU stay. We retrospectively reviewed the medical records and radiological data of adult PRES patients admitted to our tertiary care medical center. We dichotomized them into two groups based on their need for ICU care and compared their clinical, laboratory, imaging characteristics and discharge outcomes...

The cohesin protein complex mediates sister chromatid cohesion and participates in transcriptional control of genes that regulate growth and development. Substantial reduction of cohesin activity alters transcription of many genes without disrupting chromosome segregation. Drosophila Nipped-B protein loads cohesin onto chromosomes, and together Nipped-B and cohesin occupy essentially all active transcriptional enhancers and a large fraction of active genes. It is unknown why some active genes bind high levels of cohesin and some do not...

BACKGROUND: We have developed a recombinant B cell epitope-based vaccine (BM32) for allergen-specific immunotherapy (AIT) of grass pollen allergy. The vaccine contains recombinant fusion proteins consisting of allergen-derived peptides and the hepatitis B surface protein domain preS as immunological carrier. METHODS: We conducted a randomized, double-blind, placebo-controlled AIT study to determine safety, clinical efficacy and immunological mechanism of three subcutaneous injections of three BM32 doses adsorbed to aluminum hydroxide versus aluminum hydroxide (placebo) applied monthly to grass pollen allergic patients (n=70)...

The amount of people living with cancer is increasing; they live longer and have thus a higher risk of developing neurological complications. Magnetic resonance as a diagnostic procedure of choice in detecting the reasons of neurological/psychiatric symptoms in oncological patients is nowadays relatively easily accessible. Early diagnosis established by radiologists familiar with neurological entities that may follow cancer treatment allow clinicians to provide proper treatment, even if the diagnosis seems unbelievable...

S-glycosides, S-2-(2-propylthio)benzyl (SPTB) glycosides, were converted to the corresponding oxidized glycosyl donors, S-2-(2-propylsulfinyl)benzyl (SPSB) glycosides, by simple and selective oxidation. Treatment of disarmed SPSB donor and various acceptors with triflic anhydride provided the desired glycosides in good to excellent yields. Meanwhile, observation of thiosulfinate, thiosulfonate, and disulfide suggested that the leaving group was activated via an interrupted Pummerer reaction. The disarmed SPSB thioglycosyl donors could be selectively activated in the presence of various thioglycosides with remote activation mode...

OBJECTIVES: This study sought to assess the impact of chronic total occlusion (CTO) on long-term prognosis in patients with ischemic cardiomyopathy. BACKGROUND: The presence of concomitant CTO in a nonculprit lesion in acute coronary syndromes is associated with worse prognosis. Coronary artery disease is the main cause of heart failure and in many cases at least 1 CTO is observed. METHODS: The study included all patients with systolic heart failure who underwent elective coronary angiography and were registered from January 2009 to December 2014 in the ongoing single-center COMMIT-HF (COnteMporary Modalities In Treatment of Heart Failure) registry (NCT02536443)...

A 23-year-old woman presented with disturbance of consciousness and seizure. Her blood pressure was remarkably high, and brain magnetic resonance imaging (MRI) showed high-intensity T2 signals in the bilateral basal ganglia, corpus callosum, cerebral white matter, and cortex. With the administration of angiotensin II receptor blocker, the symptoms and MRI findings improved, along with normalization of blood pressure, and a diagnosis of posterior reversible leukoencephalopathy syndrome (PRES) was made. Plasma renin activity was high, and the right kidney was severely atrophic...

Hox homeodomain transcription factors are key regulators of animal development. They specify the identity of segments along the anterior-posterior body axis in metazoans by controlling the expression of diverse downstream targets, including transcription factors and signaling pathway components. The Drosophila melanogaster Hox factor Ultrabithorax (Ubx) directs the development of thoracic and abdominal segments and appendages, and loss of Ubx function can lead for example to the transformation of third thoracic segment appendages (e...
