: Skeletal manifestations of primary hyperparathyroidism (pHPT) include brown tumors (BT), which are osteoclastic focal lesions often localized in the jaws. Brown tumors are a rare manifestation of pHTP in Europe and USA; however, they are frequent in developing countries, probably related to vitamin D deficiency and longer duration and severity of disease. In the majority of cases, the removal of the parathyroid adenoma is enough for the bone to remineralize, but other cases require surgery...

BACKGROUND: In agriculture, information about the spatial distribution of crop height is valuable for applications such as biomass and yield estimation, or increasing field work efficiency in terms of fertilizing, applying pesticides, irrigation, etc. Established methods for capturing crop height often comprise restrictions in terms of cost and time efficiency, flexibility, and temporal and spatial resolution of measurements. Furthermore, crop height is mostly derived from a measurement of the bare terrain prior to plant growth and measurements of the crop surface when plants are growing, resulting in the need of multiple field campaigns...

Distal nephron acid secretion is mediated by highly specialized type A intercalated cells (A-ICs), which contain vacuolar H(+)-ATPase (V-type ATPase)-rich vesicles that fuse with the apical plasma membrane on demand. Intracellular bicarbonate generated by luminal H(+) secretion is removed by the basolateral anion-exchanger AE1. Chronically reduced renal acid excretion in distal renal tubular acidosis (dRTA) may lead to nephrocalcinosis and renal failure. Studies in MDCK monolayers led to the proposal of a dominant-negative trafficking mechanism to explain AE1-associated dominant dRTA...

BACKGROUND AND PURPOSE: Small infants with biliary atresia and hypoplastic portal veins (PV) are at risk for portal vein thrombosis (PVT) after liver transplantation (LT), which can lead to graft loss and mortality. Extra-anatomical PV reconstruction techniques have been established for adult cases of PVT; however, they have not been widely accepted for infants. METHODS: Here, we report the successful use of an extra-anatomical meso-portal venous jump graft to treat early PVT after LT in a 6-month-old infant with biliary atresia and PV hypoplasia...

The experience of the "endoscopic community" in pediatric patients is limited, but during recent years increased skills of the endoscopists and technological improvements lead to a standardization of pediatric endoscopy and the development of specialized pediatric endoscopy unit. Adverse events related to diagnostic and therapeutic endoscopy in children are usually rare. Diagnosis, prevention and treatment of complications in pediatric endoscopy is crucial when dealing with benign diseases in children. The complication rate of diagnostic EGD and colonoscopy in children are extremely low...

A functionalized magnetic nickel ferrite/manganese dioxide (NiFe2O4/MnO2) with 3D hierarchical flower-like and core-shell structure was synthesized by a facile hydrothermal approach and applied for the removal of Pb(II) ions from aqueous solutions. Batch adsorption experiments were conducted to study the effect of solution pH, initial Pb(II) concentration, and dose of absorbents on the Pb(II) removal by NiFe2O4/MnO2. The NiFe2O4/MnO2 nanocomposites showed the fast Pb(II) adsorption performance with the maximum adsorption capacity of 85...

Among the non-CO2 greenhouse gases, carbon tetrafluoride (CF4) is the most recalcitrant and should be eliminated from the atmosphere. In the present study, a non-combustion electroscrubbing method was used in an attempt to degrade CF4 with an electrogenerated Co(1+) mediator in a highly alkaline medium. The initial absorption experiments revealed 165mgL(-1) CF4 gas dissolved in 10M NaOH. Different mediator precursors, [Co(II)(CN)5](3-), [Ni(II)(CN)4](2-), [Cu(II)(OH)4](2-), and [Co(II)(OH)4](2-), were used and the electroscrubbing results showed that the electrogenerated Co(1+) or [Co(II)(OH)4](2-) precursor effectively degraded up to 99...

OBJECTIVES: Moral distress is a common experience among critical care professionals, leading to frustration, withdrawal from patient care, and job abandonment. Most of the studies on moral distress have used the Moral Distress Scale or its revised version (Moral Distress Scale-Revised). However, these scales have never been validated through factor analysis. This article aims to explore the factorial structure of the Moral Distress Scale-Revised and develop a valid and reliable scale through factor analysis...

There is a great need for viable alternatives to today's transparent conductive film using largely indium tin oxide. We report the fabrication of a new type of flexible transparent conductive film using silver nanowires (AgNW) and single-walled carbon nanotube (SWCNT) networks which are fully embedded in a UV curable resin substrate. The hybrid SWCNTs-AgNWs film is relatively flat so that the RMS roughness of the top surface of the film is 3 nm. Addition of SWCNTs networks make the film resistance uniform; without SWCNTs, sheet resistance of the surface composed of just AgNWs in resin varies from 20 Ω/sq to 10(7 )Ω/sq...

BACKGROUND: Esophageal fully covered self-expandable metal stents (FCSEMS) are indicated for the management of benign and malignant conditions of the esophagus including perforations, leaks, and strictures. FCSEMS are resistant to tissue ingrowth and are removable; however, stent migration occurs in 30-55% of cases. Endoscopic suture fixation of FCSEMS has been utilized to decrease the risk of stent migration though data supporting this practice remain limited. The primary aim of this study was to compare clinical outcomes and migration rate of patients who underwent placement of esophageal FCSEMS with and without endoscopic suture fixation...

A wide range of pathologies can cause papilloedema. Vestibular schwannoma is a benign and slow-growing tumour that causes symptoms and findings on ophthalmic examination when the diagnostic is delayed. The authors report a case of a 64-year-old male who presented with bilateral disc oedema secondary to a vestibular schwannoma grade 4. Obstructive hydrocephalus was not evident. The authors suggest that cerebrospinal fluid protein may have a role in the formation of optic disc oedema. A right suboccipital craniectomy was performed to remove the tumour, leading to secondary facial palsy...

Vascularization is essential for living tissue and remains a major challenge in the field of tissue engineering. A lack of a perfusable channel network within a large and densely populated tissue engineered construct leads to necrotic core formation, preventing fabrication of functional tissues and organs. We report a new method for producing a hierarchical, three-dimensional (3D) and perfusable vasculature in a large, cellularized fibrin hydrogel. Bifurcating channels, varying in size from 1 mm to 200-250 µm, are formed using a novel process in which we convert a 3D printed thermoplastic material into a gelatin network template, by way of an intermediate alginate hydrogel...

Carbon monoxide (CO) is a leading cause of poisoning deaths worldwide, with no available antidotal therapy. We introduce a potential treatment paradigm for CO poisoning, based on near-irreversible binding of CO by an engineered human neuroglobin (Ngb). Ngb is a six-coordinate hemoprotein, with the heme iron coordinated by two histidine residues. We mutated the distal histidine to glutamine (H64Q) and substituted three surface cysteines with less reactive amino acids to form a five-coordinate heme protein (Ngb-H64Q-CCC)...

BACKGROUND: Acupuncture can be used to manage chronic pain. The most common complications related to acupuncture include pain, bruising, bleeding, or symptom exacerbation. Rarely, more serious adverse events occur, including infection, pneumothorax, septic arthritis, and peripheral nerve injury. To our knowledge, there are no reports of complications associated with acupuncture following spinal instrumentation. PURPOSE: To report a case of deep infection as a rare complication of acupuncture following posterior spinal fusion for adolescent idiopathic scoliosis...

Arylsulfatase B (ARSB; N-acetylgalactosamine 4-sulfatase) is reduced in several malignancies, but levels in melanoma have not been investigated previously. Experiments were performed in melanoma cell lines to determine ARSB activity and impact on melanoma invasiveness. ARSB activity was reduced ~50% in melanoma cells compared to normal melanocytes. Silencing ARSB significantly increased the mRNA expression of chondroitin sulfate proteoglycan(CSPG)4 and pro-matrix metalloproteinase(MMP)-2, known mediators of melanoma progression...

Missing data is a common issue in community health and epidemiological studies. Direct removal of samples with missing data can lead to reduced sample size and information bias, which deteriorates the significance of the results. While data imputation methods are available to deal with missing data, they are limited in performance and could introduce noises into the dataset. Instead of data imputation, a novel method based on additive least square support vector machine (LS-SVM) is proposed in this paper for predictive modeling when the input features of the model contain missing data...

Macroautophagy/autophagy is a conserved catabolic process through which cellular excessive or dysfunctional proteins and organelles are transported to the lysosome for terminal degradation and recycling. Over the past few years increasing evidence has suggested that autophagy is not only a simple metabolite recycling mechanism, but also plays a critical role in the removal of intracellular pathogens such as bacteria and viruses. When autophagy engulfs intracellular pathogens, the pathway is called 'xenophagy' because it leads to the elimination of foreign microbes...

Large tumours of the mandible need immediate reconstruction to provide continuity of the mandible, satisfactory function of the jaw, as well as an acceptable aesthetic outcome. In this prospective study we described the immediate reconstruction of the mandible using computer aided design and 15 rapid prototyped patient specific implants (PSI) in 14 patients suffering from benign or malignant tumours demanding continuity resection of the mandible. The scaffold PSI was filled with β-tricalcium phosphate granules and autologous bone...

The nanocomposites based on copper, zinc and nickel were loaded on activated carbon (Cu-Zn-Ni-NPs-AC) and cobalt and nickel nanoparticles was loaded on γ-alumina (Ni-Co-NPs-γAl2O3) and applied for removal of hydrogen sulfide (H2S) from natural gas and their efficiency were compared. Cu-Zn-Ni/AC and Ni-Co/γ-Al2O3 was characterized using different techniques such as energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). The effects of variables such as amount of adsorbent, flow rate, temperature, pressure and volume of gas on H2S removal were examined and optimum values were found to be 0...

INTRODUCTION: To the best of our knowledge, the presence of a trilobed nonfunctional giant pituitary adenoma has never been described before in the literature. These tumors present unique diagnostic and therapeutic challenges. Tumors of this etiology can be managed with pharmacologic treatment or aggressive surgical intervention. The following case illustrates an unique visual presentation of a giant pituitary adenoma. CASE PRESENTATION: We report the case of a 40-year-old Hispanic man who presented with new onset seizures...
