Imidazolidinone derivatives of a range of aromatic α-amino acids, on treatment with phosgene and potassium iodide, undergo a mild Bischler-Napieralski-style cyclocarbonylation reaction that generates a tricyclic lactam by insertion of a C═O group between amino acid nitrogen and the ortho position of the aryl substituent. Regio- and diastereoselective functionalization of the lactam generates a library of substituted dihydroisoquinolinones and their congeners in enantioenriched form.

Bullous pemphigoid (BP) is a chronic autoimmune skin disease. Aquaporin 3 (AQP 3) has a possible role in the pathogenesis of many dermatological diseases. In this work, we aimed to evaluate the expression of AQP 3 in BP. Perilesional skin biopsies were taken from 24 BP patients and 13 controls. The biopsies were stained by direct immunofluorescence using rabbit anti-human AQP 3 FITC antibody. The expression of AQP 3 was weak in 5 patients (20.8%), moderate in 18 patients (75%), strong in 1 patient (4.2%) in the suprabasal layers...

BACKGROUND: Achieving margin negative resection is a significant determinant of outcome in pancreatic adenocarcinoma (PDA). However, because of the fibrotic nature of PDA, it can be difficult to discriminate fibrosis from active disease intra-operatively. We sought to determine if post-hoc video review of robotic pancreatico-duodenectomy (RPD) could predict the portal/superior mesenteric vein (PV/SMV) margin status on final pathology. METHODS: Experienced pancreatic surgeons, blinded to patient and operative variables, reviewed the PV/SMV margin for available RPD videos of consecutive PDA patients from 9/2012 through 6/2017...

Chronic kidney disease (CKD) is an asymptomatic disease associated with high morbidity and life-threatening complications that lead to decreased life expectancy. Worldwide prevalence of CKD is escalating at an alarming rate. Large population-based representative surveys have been reported in Western countries to estimate the prevalence of the disease. However, there is paucity of data as far as developing nations are concerned. Asia is the world's largest continent accommodating maximum number of under-developed and developing countries with an unclear picture of prevalence of CKD...

Imaging plays a critical role in the management of the highly complex and widely diverse central nervous system (CNS) malignancies in providing an accurate diagnosis, treatment planning, response assessment, prognosis, and surveillance. Contrast-enhanced magnetic resonance imaging (MRI) is the primary modality for CNS disease management due to its high contrast resolution, reasonable spatial resolution, and relatively low cost and risk. However, defining tumor response to radiation treatment and chemotherapy by contrast-enhanced MRI is often difficult due to various factors that can influence contrast agent distribution and perfusion, such as edema, necrosis, vascular alterations, and inflammation, leading to pseudoprogression and pseudoresponse assessments...

Many tumor-suppressor genes contain CpG islands in their promoter regions which raised the necessity of investigating the role of methylation in silencing these genes. We examined p16 methylation as a potential biomarker in the peripheral blood of colorectal cancer (CRC) patients. Using methylation-specific polymerase chain reaction method, the methylation status of p16 was investigated in the tumor tissue and blood of 65 CRC patients and blood samples from 70 healthy control individuals. Also, the relationship between p16 methylation level and the clinical-pathological findings in CRC was evaluated...

BACKGROUND: Late-life depression (LLD) is a disabling disorder and antidepressants are ineffective in as many as 60% of cases. Converging evidence shows a strong correlation between LLD and subsequent risk of cardiovascular disease. There is a need for new, well-tolerated, non-pharmacological augmentation interventions that can treat depressive symptoms as well as improve heart rate variability (HRV), an important prognostic marker for development of subsequent cardiovascular disease...
