The viability of noble gas axled boron nanowheel, NgnMB10- (Ng = Ar-Rn, M = Nb, Ta; n = 1, 2), is explored via ab initio computations. In the resulting Ng2-M complexes, the Ng-M-Ng nanorod passes through the center of B10- ring, providing them with an inverse sandwich like structure. While in single Ng bound analogue, the Ng binding enthalpy (Hb) at 298 K ranges from 2.5 to 10.6 kcal/mol, in two Ng bound cases it becomes very low for Ng2MB10- -> Ng + NgMB10- dissociation channel, except for Rn case. For a given Ng, Ta has slightly higher Ng binding ability than Nb...

PURPOSE: LND may benefit patients at increased risk of lymph node (LN) metastases from renal cell carcinoma (RCC). We therefore evaluated the association of LND with survival among high-risk patients undergoing radical nephrectomy (RN) for RCC. MATERIALS AND METHODS: We identified 2,722 patients with M0 RCC who underwent RN with or without LND at two international centers from 1990-2010. The associations of LND with development of distant metastases, cancer-specific mortality (CSM), and all-cause mortality (ACM) were evaluated using propensity score techniques and traditional multivariable Cox regression...

The non-lab Framingham algorithm, which substitute body mass index for lipids in the laboratory based (lab-based) Framingham algorithm, has been validated among African Americans (AAs). However, its cost-effectiveness and economic tradeoffs have not been evaluated. This study examines the incremental cost-effectiveness ratio (ICER) of two cardiovascular disease (CVD) prevention programs guided by the non-lab versus lab-based Framingham algorithm. We simulated the World Health Organization CVD prevention guidelines on a cohort of 2690 AA participants in the Atherosclerosis Risk in Communities (ARIC) cohort...

Radiation necrosis remains an irreversible long-term side-effect following radiotherapy to the brain. The ability to predict areas that could ultimately develop into necrosis could lead to prevention and management of radiation necrosis. Materials and Methods: Fischer 344 rats were irradiated using two platforms (micro-CT irradiator and x-RAD 225 IGRT) with radiation up to 30 Gy for the micro-CT and 40 Gy for the xRAD-224 to half the brain. Animals were subsequently imaged using a 9.4T MRI scanner every 2-4 weeks for up to 28 weeks using a 7-echo gradient echo sequence...

Radon (Rn-222), thoron (Rn-220) and its progeny are the natural radioactive gases emitted everywhere in different concentration. These carcinogenic substances were known to be responsible for lung cancer. Human exposure of these gases in an indoor environment was principally dependent on the house types like concrete, slate, mud-tin etc. Rate of exposure is also influenced by unplanned construction and associated poor ventilation.The study of inhalation dose with house type and the associated indoor environment were important to study the exposure due to natural ionising radiation...

Oxidation of the P(III) dianion [S-P(µ-NtBu)]22- (1) with elemental sulphur, selenium and tellurium gives the P(V) dianions [(S)(E)P(µ-NtBu)]22- (E = S (6a), Se (6b), Te (6c)). Although 6c proves to be too unstable, the S,S-dianion 6a and ambidentate S,Se-dianion 6b are readily transferred intact to main group and transition metal elements, producing a range of new cage and coordination compounds. While their coordination characteristics are in many ways similar to closely-related isoelectronic phosph(V)azane anions [(E)(RN=)P(µ-NtBu)]22-, the sterically unhindered nature of 6 introduces an expanded range of coordination modes, i...

BACKGROUND: Failure on the National Council Licensure Examination for Registered Nurses (NCLEX-RN) is a devastating experience. Most research related to NCLEX-RN is focused on predicting and preventing failure. Despite these efforts, more than 20,000 nursing school graduates experience failure on the NCLEX-RN each year, and there is a paucity of literature regarding remediation after failure. METHOD: The aim of this article is to describe an individualized tutoring approach centered on establishing a trusting relationship and incorporating two core strategies for remediation: the nugget method, and a six-step strategy for question analysis...

Although the noble gas (Ng) compounds with either Ng-C or Ng-N bonds have been reported in the literature, compounds containing both the bonds are not known. The first set of systems having C-Ng-N bonding unit is predicted herein through the analysis of stability and bonding in NCNgNSi (Ng = Kr-Rn) family. While the Xe and Rn inserted analogues are thermochemically stable with respect to all dissociation channels, but for the one producing CNSiN and free Ng, NCKrNSi has another additional three-body dissociation channel, NCKrNSi -> CN + Kr + NSi, which is exergonic by -9...

BACKGROUND: In patients with bicuspid aortic valve (BAV), complications including progressive aortic stenosis and aortic dilatation develop over time. The morphology of cusp fusion is one of the determinants of the type and severity of these complications. We present the association of morphology of cusp fusion in BAV patients with distinctive genetic syndromes. METHODS: The Mayo Clinic echocardiography database was retrospectively reviewed to identify patients (age ≤ 22 years) diagnosed with BAV from 1990 to 2016...

Bicuspid aortic valve (BAV) is the most common congenital heart defect. BAV is associated with aortic stenosis and insufficiency, and aortic dilation in adult groups, but data in pediatric groups are limited. We sought to assess the impact of BAV morphology on aortic valve disease and aortic dilation in pediatric patients. We performed a retrospective review of all echocardiograms in patients with isolated BAV who were followed at our institution from July 2002 to July 2012. BAV morphology, aortic valve stenosis and/or insufficiency, and aortic dimensions were measured manually...

We previously reported that interleukin-6 (IL-6) in the red nucleus (RN) is up-regulated at 3weeks after spared nerve injury (SNI), and plays facilitated role in the later maintenance of neuropathic pain. The current study aimed to reveal the roles of different signaling pathways, including Janus kinase/signal transducer and activator of transcription 3 (JAK/STAT3), extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (MAPK) and phosphatidylinositide 3-kinase/protein kinase B (PI3K/AKT), in RN IL-6-mediated pain modulation...

This is a reevaluation of registered nurse (RN) supply and demand from 2016 to 2030 using a previously published work forecast model and grading methodology with more recent workforce data. There will be a shortage of 154 018 RNs by 2020 and 510 394 RNs by 2030; the South and West regions will have higher shortage ratios than Northeast and Midwest regions. This reflects a nearly 50% overall improvement when compared with the authors' prior study, and the low-performing states have improved from 18 "D" and 12 "F" grades as published earlier to 13 "D" and 1 "F" in this study...
