Net NH4+ and NO3− fluxes, and expression of NH4+ and NO
submitted by creckit 16 minutes ago - Topic: Forestry
Net NH4+flux was higher in fine roots ofP. simoniiafter NaCl treatment compared to the NO3−flux which was consistent with the expression levels ofAMTsandNRTs.The characteristics of nitrogen uptake under salt stress would provide insights into the mechanisms of salt tolerance in plants. In the present study, net NH4+ and NO3− fluxes were measured using the non-invasive micro-test technique, ...

Psychische Belastung und Risikowahrnehmung bei Einsatzkräften des Technischen Hilfswerks
submitted by spoz 17 minutes ago - Topic: Health
Einsatzkräfte sind durch ihre Tätigkeit immer wieder einem Verletzungsrisiko ausgesetzt. Psychologische Modelle zur Belastungsverarbeitung gehen davon aus, dass die Bewertung der persönlichen Gefährdung (Risikowahrnehmung) in Zusammenhang mit psychischer Belastung steht. Ziel der Studie war es, den Zusammenhang von Risikowahrnehmung, psychischer Belastung und Belastungsverarbeitung zu unter...

Target silencing of components of the conserved oligomeric Golgi complex impairs HIV-1 replication
submitted by grenzy 17 minutes ago - Topic: Biology
All viruses require host cell factors to replicate. A large number of host factors have been identified that participate at numerous points of the human immunodeficiency virus 1 (HIV-1) life cycle. Recent evidence supports a role for components of the trans-Golgi network (TGN) in mediating early steps in the HIV-1 life cycle. The conserved oligomeric Golgi (COG) complex is a heteroctamer comple...

Human cytomegalovirus immediate early protein 2 enhances myocardin-mediated survival of rat aortic smooth muscle cells
submitted by grenzy 17 minutes ago - Topic: Biology
Human cytomegalovirus (HCMV) may increase the incidence of restenosis and predispose to atherosclerosis. The lesions of restenosis and atherosclerosis often contain smooth muscle cells (SMCs) with high rates of proliferation and apoptosis. One of the immediate early (IE) gene products of HCMV-IE2 affects transcriptional activities of some cellular factors in SMCs, including myocardin. In this s...

Questioning the use of an amphibian colour morph as an indicator of climate change
submitted by csogimd 18 minutes ago - Topic: Environment
The effects of recent climate changes on earth ecosystems are likely among the most important ecological concerns in human history. Good bioindicators are essential to properly assess the magnitude of these changes. In the last decades, studies have suggested that the morph proportion of the eastern red-backed salamander (Plethodon cinereus), one of the most widely distributed and abundant vert...

Agricultural peatland restoration: effects of land-use change on greenhouse gas (CO2 and CH4) fluxes in the Sacramento-San Joaquin Delta
submitted by csogimd 18 minutes ago - Topic: Environment
Agricultural drainage of organic soils has resulted in vast soil subsidence and contributed to increased atmospheric carbon dioxide (CO2) concentrations. The Sacramento-San Joaquin Delta in California was drained over a century ago for agriculture and human settlement and has since experienced subsidence rates that are among the highest in the world. It is recognized that drained agriculture in...

Carbon accumulation in a permafrost polygon peatland: steady long term rates in spite of shifts between dry and wet conditions
submitted by csogimd 18 minutes ago - Topic: Environment
Ice-wedge polygon peatlands contain a substantial part of the carbon stored in permafrost soils. However, little is known about their long term carbon accumulation rates (CAR) in relation to shifts in vegetation and climate. We collected four peat profiles from one single polygon in NE Yakutia and cut them into contiguous 0.5 cm slices. Pollen density interpolation between AMS 14C dated levels ...

Strong YB-1 Expression Predicts Liver Recurrence Following Resection for Colorectal Metastases
submitted by iddeiback2 24 minutes ago - Topic: Health
The Y-box binding protein-1 (YB-1) is a multifunctional oncoprotein involved in the proliferation and aggressiveness of cancer cells. The aim of this study was to determine whether strong YB-1 expression in neoplastic cells of colorectal liver metastases (CRLM) may have an impact on liver disease-free survival following liver resection. Immunohistochemistry was performed to evaluate YB-1 in 66 ...

Morbidity of Loop Ileostomy Closure after Restorative Proctocolectomy for Ulcerative Colitis and Familial Adenomatous Polyposis: a Systematic Review
submitted by iddeiback2 24 minutes ago - Topic: Health
Temporary loop ileostomy is a routine procedure to reduce the morbidity of restorative proctocolectomy. However, morbidity of ileostomy closure could reduce the benefit of this concept. The objective of this systematic review was to assess the risks of ileostomy closure after restorative proctocolectomy for ulcerative colitis or familial adenomatous polyposis. Publications in English or German ...

Does BMI Predict Recurrence or Complications After Reoperative Reflux Surgery? Review of a Single Center’s Experience and a Comparison of Outcomes
submitted by iddeiback2 24 minutes ago - Topic: Health
Obese patients who fail primary surgical management of gastroesophageal reflux present a significant challenge. We reviewed our outcomes with reoperative reflux surgery in obese (body mass index (BMI) >30) and nonobese patients to identify predictors of failure and complications and evaluate whether reoperative fundoplication is the ideal solution for obese patients. We conducted a retrospectiv...

Patency Rates of Portal Vein/Superior Mesenteric Vein Reconstruction After Pancreatectomy for Pancreatic Cancer
submitted by iddeiback2 24 minutes ago - Topic: Health
Pancreatectomy with venous reconstruction (VR) for pancreatic cancer (PC) is occurring more commonly. Few studies have examined the long-term patency of the superior mesenteric-portal vein confluence following reconstruction. From 2007 to 2013, patients who underwent pancreatic resection with VR for PC were classified by type of reconstruction. Patency of VR was assessed using surveillance comp...

Evaluation of Extractables in Processed and Unprocessed Polymer Materials Used for Pharmaceutical Applications
submitted by berd 31 minutes ago - Topic: Health
Polymeric materials are often used in pharmaceutical packaging, delivery systems, and manufacturing components. There is continued concern that chemical entities from polymeric components may leach into various dosage forms, particularly those that are comprised of liquids such as parenterals, injectables, ophthalmics, and inhalation products. In some cases, polymeric components are subjected t...

Atypical hematologic and renal manifestations in Neurofibromatosis type I: Coincidence or pathophysiological link?
submitted by bollyeon 34 minutes ago - Topic: Biology
Neurofibromatosis type 1 (NF1) is an autosomal dominant, multi-system, neurocutaneous disorder that predisposes to the development of benign and malignant tumours with a birth incidence rate of 1 in 2500-3000. 50% of cases are sporadic. The diagnosis is exclusively based on clinical assessment with clinical diagnostic criteria such as café-au-lait spots, neurofibromas, axillary or groin freckl...

19q13.32 microdeletion syndrome: Three new cases

A previous report described a unique phenotype associated with an apparently de novo 732 kb 19q13.32 microdeletion, consisting of intellectual disability, facial asymmetry, ptosis, oculomotor abnormalities, orofacial clefts, cardiac defects, scoliosis and chronic constipation. We report three unrelated patients with developmental delay and dysmorphic features, who were all found to have interst...

Rheumatoid arthritis: Microvascular clues to hemiplegia-induced asymmetric RA
submitted by wf1321 38 minutes ago - Topic: Health
Patients with rheumatoid arthritis who are hemiplegic, and also mice with denervated hindpaws and experimentally-induced arthritis, can develop unilateral arthritis. But is a specific branch of the nervous system involved in this asymmetry, or does a lack of innervation alter the microvasculature and promote vascular impermeability?
