A 55-year-old male presented, in June 2013, with left flank pain. Investigations revealed a complete staghorn stone. He had undergone two sittings of extracorporeal shock wave lithotripsy (ESWL) in 2008 for left renal stone. One year subsequent to this, he was diagnosed with hypertension and diabetes. The management of complete staghorn stones in a single sitting is a difficult proposition. Percutaneous nephrolithotomy (PCNL) is the gold standard to manage such stones. The patient was subjected to PCNL, and complete clearance was achieved in one sitting...

INTRODUCTION: Effective medical expulsion for ureteric stones with α-blockers offers numerous advantages over surgical alternatives. However, its effectiveness remains uncertain and with the publication of new trial data, the available evidence requires reappraisal. OBJECTIVE: The aim of this study was to assess the efficacy of α-blockers the management of ureteric lithiasis. METHODS: A systematic review of the literature, with predefined search criteria, was conducted using PubMed and Embase...

PURPOSE: To investigate the effect of performing shockwave lithotripsy (SWL) before retrograde intrarenal surgery (RIRS) on the treatment outcomes of patients with nephrolithiasis. MATERIALS AND METHODS: The data of 189 patients with renal stones who underwent RIRS from July 2007 to July 2014 was reviewed retrospectively. Patients with stones larger than 1.5 cm were recommended to undergo SWL before RIRS. Patients were divided into 2 groups based on whether the preoperative SWL was performed (group 1, n=68) or not (group 2, n=121)...

Maintenance of telomeres by telomerase permits continuous proliferation of rapidly dividing cells, including the majority of human cancers. Despite its direct biomedical significance, the architecture of the human telomerase complex remains unknown. Generating homogeneous telomerase samples has presented a significant barrier to developing improved structural models. Here we pair single-molecule Förster resonance energy transfer (smFRET) measurements with Rosetta modeling to map the conformations of the essential telomerase RNA core domain within the active ribonucleoprotein...

Dietary methionine restriction (MR) produces a rapid and persistent remodeling of white adipose tissue (WAT), increase in energy expenditure (EE), and enhancement of insulin sensitivity. Recent work established that hepatic expression of FGF21 is robustly increased by MR. Based on the known physiological effects of FGF21, Fgf21(-/-) mice were used to test whether FGF21 is an essential mediator of the physiological effects of dietary MR. The MR-induced increase in energy intake and EE, and activation of thermogenesis in WAT and BAT were lost in Fgf21(-/-) mice...

INTRODUCTION: Numerous studies have reported on regional or national trends of stone disease treatment. However, no paper has yet examined the global trends of intervention for stone disease. METHODS AND MATERIALS: A systematic review of papers from 2004 to September 2016 for all English language articles reporting on trends of surgical treatment of stone disease was performed. Authors were contacted in the case of data not being clear. If the authors did not reply, data was estimated from graphs or tables...

BACKGROUND: In a four-generation Caucasian family variably diagnosed with autosomal dominant (AD) Stickler or Wagner disease, commercial gene screening failed to identify a mutation in COL2A1 or VCAN. We utilized linkage mapping and exome sequencing to identify the causal variant. MATERIALS AND METHODS: Genomic DNA samples collected from 40 family members were analyzed. A whole-genome linkage scan was performed using Illumina HumanLinkage-24 BeadChip followed by two-point and multipoint linkage analyses using FASTLINK and MERLIN...

Starting from the question the youthful Carl Gustav pondered as he sat on 'his' stone - 'Am I he who sits on the stone, or am I the stone on which he sits?' - the author has attempted to show that, for Jung, the idea of identity is founded on a wilful non-determination. This stance results in ethical and methodological repercussions that differentiate it both from the Freudian project and from Hindu and Buddhist thought, while at the same time having much in common with them. The paper refers to the notions of emergence and (Varela et al...

INTRO: Common duct stones can be diagnosed by magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound/endoscopic retrograde cholangiopancreatography (EUS/ERCP), and intra-operative cholangiogram (IOC). In 2015, our group adopted a standard approach of preoperative EUS/ERCP followed by laparoscopic cholecystectomy for patients with an admission bilirubin over 4.0 (mg/dL). For bilirubin less than 4.0, laparoscopic cholecystectomy with IOC was the initial procedure. Post-operative EUS/ERCP with endoscopic sphincterotomy was pursued for positive IOC...

Viticulture has contributed to shaping cultural landscapes in several regions across all continents. Recent farming intensification is causing landscape homogenization and biodiversity loss in several of those areas, but knowledge about the impacts on biodiversity in vineyards is still scarce. Simplified agro-ecosystems resulting from intensification host mainly generalist and common species, which still play a key role in the regulation of ecosystems and in the provision of ecosystem services. We assessed the abundance of 11 common bird species at 47 linear transects in a vineyard-dominated landscape in Trentino (NE Italy), in both spring and winter, and analysed abundance variation in relation to three independent groups of predictors: landscape, management, and topographic-climatic variables...

A subset of patients requiring coronary revascularization and valve surgery may benefit from a combined approach of percutaneous coronary intervention (PCI) and valve surgery, as opposed to the standard median sternotomy approach of combined coronary artery bypass and valve surgery. To evaluate its potential benefits and limitations, a literature search was performed using PubMed, EMBASE, Ovid, and the Cochrane library, through March 2016 to identify all studies involving a combined approach of PCI and valve surgery in patients with coronary artery and valvular disease...

Many lines of evidence have indicated that both genetic and non-genetic determinants can contribute to intra-tumor heterogeneity and influence cancer outcomes. Among the best described sub-population of cancer cells generated by non-genetic mechanisms are cells characterized by a CD44+/CD24- cell surface marker profile. Here, we report that human CD44+/CD24- cancer cells are genetically highly unstable due to intrinsic defects in their DNA repair capabilities. In fact, in CD44+/CD24- cells constitutive activation of the TGF-beta axis was both necessary and sufficient to reduce the expression of genes that are critical in coordinating DNA damage repair mechanisms...

High serum IgG4 concentrations are a striking feature of many patients with IgG4-related disease (IgG4-RD). Blood levels of IgG4 often reach ten, twenty, and even thirty or more times higher than the upper limit of normal. Under the proper clinical circumstances, the finding of an elevated serum IgG4 concentration serves as a useful biomarker for the diagnosis of this condition. This serum IgG4 elevation quickly called attention to the possibility of therapies targeting cells of the B lymphocyte lineage. In addition, a greater understanding of the cellular mechanisms that underpin IgG4-RD has identified peripheral blood plasmablasts as a promising biomarker for this disease...
