Power production and microbial community composition in thermophilic acetate-fed up-flow and flow-through microbial fuel cells.

The microbial communities developed from a mixed-species culture in up-flow and flow-through configurations of thermophilic (55 °C) microbial fuel cells (MFCs), and their power production from acetate, were investigated. The up-flow MFC was operated for 202 days, obtaining an average power density of 0.13 W/m, and Tepidiphilus was the dominant transcriptionally-active microorganisms. The planktonic community developed in the up-flow MFC was used to inoculate a flow-through MFC resulting in the prolif...

Evidence of the Impact of the Tips From Former Smokers Campaign: Results From the Behavioral Risk Factor Surveillance System.

The Tips From Former Smokers campaign (Tips) has demonstrated significant impact as a population-based intervention for smoking cessation in the United States. Since 2012, evaluations of Tips have relied on web-panel data to attribute the campaign to smoking cessation outcomes. We re-examined the relationship between market-level doses of the campaign and quit attempts by using Behavioral Risk Factor Surveillance System (BRFSS) data to triangulate prior findings. We found that Tips was associated with incre...

Correlation of spontaneous and traumatic anterior skull base CSF leak flow rates with fluid pattern on early, delayed, and subtraction volumetric extended echo train T2-weighted MRI.

CSF leakage is a potentially fatal condition that may result when a skull base dural defect permits CSF communication between the cranial vault and sinonasal cavities. Flow rate is an important property of CSF leaks that can contribute to surgical decision-making and predispose patients to complications and inferior outcomes. Noninvasive preoperative prediction of the leak rate is challenging with traditional diagnostic tools. The present study compares fluid configurations on early and late volumetric exte...

On the use of ultrasonic dental scaler tips as cleaning technique of microfiltration ceramic membranes.

The use of ultrasonic dental scaler (UDS) tips has been investigated for cleaning ceramic membranes fouled when filtering cactus juice. Thin and long tips having a larger coverage exhibited the best performance for removing the cake layer deposited on the membrane surface. Such tips cleaned an area equivalent to almost one third of total area of the membrane surface. However, the cleaned area could be increased notoriously if the membrane were placed in rotatory disc holder. The resistance-in series model a...

Balloon-occluded Retrograde Transvenous Obliteration Versus Transjugular Intrahepatic Portosystemic Shunt for Gastric Varices: A Meta-Analysis.

Balloon-occluded retrograde transvenous obliteration (BRTO) and transjugular intrahepatic portosystemic shunt (TIPS) are well-validated techniques in the management of portal hypertensive gastric variceal bleeding when medical management alone is not sufficient. However, despite their effectiveness, the adverse effects from both procedures make each technique more suitable to different cohorts of patient's depending on presence or lack of certain comorbidities. This study aims to compare clinical outcomes o...

Physicochemical Properties and Bioactive Potential of a New Epoxy Resin-based Root Canal Sealer.

The aim of this study was to evaluate physicochemical properties and bioactive potential of Sealer Plus, in comparison with MTA Fillapex, Sealapex and AH Plus. Setting time, flow, and radiopacity were evaluated based on ISO 6876 Standard. Flow was also assessed in area (mm²). The solubility and volumetric change of the sealers were evaluated after 7 and 30 days of immersion in distilled water. Solubility was evaluated by the difference in mass of materials before and after immersion. Volumetric change was ...

Radiotherapy isocenters verified by matching to bony landmarks of the canine and feline head differ when localized using volumetric vs planar imaging.

The "gold standard" for verification of patient positioning before linear accelerator-based stereotactic radiation therapy is kilovoltage cone-beam computed tomography (kV-CBCT), which is not uniformly available or utilized; planar imaging is sometimes used instead. The primary aim of this study was to determine if the position of the bony skull, when used as a surrogate for isocenter verification, is different when orthogonal megavoltage portal (MV) or kilovoltage (kV/kV) radiographs are used for image-gui...

Geographic variations and potential macro-environmental exposure of hypertension: from the China hypertension survey.

The study aimed to investigate the spatial variation of hypertension (HTN) and the associations between the risk of HTN and altitude, longitude, latitude in Chinese population.

Role of microtubule +TIPs and -TIPs in spermatogenesis - insights from studies of toxicant models.

During spermatogenesis, preleptotene spermatocytes and haploid spermatids, lacking lamellipodia and filopodia to elicit cell movement rely on Sertoli cells for transport across the blood-testis barrier (BTB) and the adluminal compartment of the epithelium, respectively. Tracks provided by microtubules (MTs) across the epithelium are essential to support germ cell transport, but the mechanism(s) remain elusive. Studies have provided insightful information through the use of toxicant models. Herein, we summar...

Disparities in Electronic Patient Portal Use in Prenatal Care: Retrospective Cohort Study.

Electronic patient portals are websites that provide individuals access to their personal health records and allow them to engage through a secure Web-based platform. These portals are becoming increasingly popular in contemporary health care systems. Patient portal use has been found to be beneficial in multiple specialties, especially in the management of chronic disease. However, disparities have been identified in portal use in which racial and ethnic minorities and individuals with lower socioeconomic ...

Analysis of volumetric BMD in people with Down syndrome using DXA-based 3D modeling.

We analyzed volumetric bone mineral density, by 3D analysis, in 76 people with Down syndrome and 76 controls. People with Down syndrome, particularly men, have a lower hip volumetric bone mineral density than the general population. Besides, volumetric bone mineral density declines more rapidly in Down syndrome.

Low-flow mediated constriction as a marker of endothelial function in healthy pregnancy and preeclampsia: A pilot study.

Overwhelming clinical evidence exists on disturbed vascular and endothelial function in the pathophysiology of preeclampsia (PE). In a non-pregnant (NP) population, L-FMC (low-flow mediated constriction) provides insight in the 'resting' endothelial capacity in contrast to the gold standard of flow mediated dilatation (FMD), reflecting endothelial nitric oxide bioavailability.

The Impact of CYP24A1 Polymorphisms on Hypertension Susceptibility.

Hypertension is one of the leading causes of human death and disability. CYP24A1 regulates vitamin D activity and is closely linked to hypertension. However, the relationship between CYP24A1polymorphisms and hypertension risk remains unclear.

Band ligation versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis.

Portal hypertension commonly accompanies advanced liver disease and often gives rise to life-threatening complications, including haemorrhage from oesophageal and gastrointestinal varices. Variceal haemorrhage commonly occurs in children with chronic liver disease or portal vein obstruction. Prevention is therefore important. Following numerous randomised clinical trials demonstrating efficacy of non-selective beta-blockers and endoscopic variceal ligation in decreasing the incidence of variceal haemorrhage...

Feasibility and Short-Term Stability of Portal Vein Infusion Port Placement by Transjugular Access.

Six pigs underwent implantation of a portal vein infusion port by transjugular access. The technical success rate was 100% (n = 6), with no surgical complications or deaths. At 1 month after implantation, the catheter tip had moved from the splenic vein to the main portal vein, while the catheter protruded into the right ventricle through the right atrium in all cases. Hence, the infusion port system has not been used in clinical practice due to its obvious displacement after implantation. However, this st...

Systemic administration of pentoxifylline attenuates the development of hypertension in renovascular hypertensive rats.

There is evidence to suggest that hypertension involves a chronic low-grade systemic inflammatory response; however, the underlying mechanisms are unclear. To further understand the role of inflammation in hypertension, we used a rat renovascular model of hypertension in which we administered the TNF-α synthesis inhibitor pentoxifylline (PTX, 30 mg/kg/day) in the drinking water for 60 days. In conscious rats, PTX administration significantly attenuated the development of hypertension (systolic blood pres...
