Abstract
The ligands 1,10-phenanthroline, (P) and para-aminobenzoate, (B); as well as their corresponding MnPB complex [bis-(dimanganese di-μ-paraaminobenzoate dichloro diphenanthroline)] have been investigated as inhibitors of mild steel corrosion in H2SO4 (0.5 M) solutions via potentiodynamic and electrochemical impedance spectroscopy techniques. Stability of the prepared complex was examined by UV-visible spectroscopy. The corrosion inhibition, thermodynamics, and adsorptive properties obtained have shown that MnPB complex has remarkable effects in the acidic solutions. Theoretical fitting of different adsorption isotherms such as Langmuir, Flory–Huggins, and the kinetic-thermodynamic models were tested and the thermodynamic activation parameters were calculated. The data revealed that the corrosion inhibition mechanism of mild steel in acidic solutions by the MnPB complex goes via physicochemical adsorption.

Stimulation and functional imaging studies have revealed the existence of a large network of cortical regions involved in the regulation of heart rate. However, very little is known about the link between cortical neural firing and cardiac-cycle duration (CCD). Here, we analyze single-unit and multiunit data obtained in humans at rest, and show that firing rate covaries with CCD in 16.7% of the sample (25 of 150). The link between firing rate and CCD was most prevalent in the anterior medial temporal lobe (entorhinal and perirhinal cortices, anterior hippocampus, and amygdala), where 36% (18 of 50) of the units show the effect, and to a lesser extent in the mid-to-anterior cingulate cortex (11.1%, 5 of 45). The variance in firing rate explained by CCD ranged from 0.5 to 11%. Several lines of analysis indicate that neural firing influences CCD, rather than the other way around, and that neural firing affects CCD through vagally mediated mechanisms in most cases. These results show that part of the spontaneous fluctuations in firing rate can be attributed to the cortical control of the cardiac cycle. The fine tuning of the regulation of CCD represents a novel physiological factor accounting for spontaneous variance in firing rate. It remains to be determined whether the “noise” introduced in firing rate by the regulation of CCD is detrimental or beneficial to the cognitive information processing carried out in the parahippocampal and cingulate regions.SIGNIFICANCE STATEMENTFluctuations in heart rate are known to be under the control of cortical structures, but spontaneous fluctuations in cortical firing rate, or “noise,” have seldom been related to heart rate. Here, we analyze unit activity in humans at rest and show that spontaneous fluctuations in neural firing in the medial temporal lobe, as well as in the mid-to-anterior cingulate cortex, influence heart rate. This phenomenon was particularly pronounced in the entorhinal and perirhinal cortices, where it could be observed in one of three neurons. Our results show that part of spontaneous firing rate variability in regions best known for their cognitive role in spatial navigation and memory corresponds to precise physiological regulations.

Authors: Kumar Thirunavukkarasu Bharath , Kumar Earan Sujay 
Published: March 2019

Background: Nutritional factors like breast feeding practices, weaning practices and diet during illness influence the growth and development of children. Recurrent infections are other important factors that lead to malnutrition.Methods: This was a non-randomized prospective study using pretested, predesigned questionnaires. Study was done in a single centre to determine the pattern of feeding practices and malnutrition among infant and young children. This study was carried out in the Department of Paediatrics at Sri Manakula Vinayagar Medical College and hospital, Puducherry.Results: Out of the 200 babies studied, 22% of the babies were exclusively breast fed and 5% of the babies were bottle fed. The remaining 73% of the babies were on both breasts feeding and bottle feeding. A 52% of children in the age group 6-12 months, 50% children under12-24 months and 52% of children >24 months were found to be malnourished according to WHO growth standards.Conclusions: Quantity and quality of complementary feeds given is inadequate due to lake of awareness, fear and food stigmata. Hence feeding practices are far from satisfactory. Complementary feeding and weaning practice guidelines are better practiced as the age advances but their practice at a younger age would lead to a better outcome.

Published: March 2019

PurposeThis evidence-based practice project evaluated the efficacy of a respiratory algorithm administered by specially trained transition nurses on the reduction of preventable NICU admissions for infants experiencing mild respiratory distress during transition.DesignA retrospective chart review compared a cohort of newborn admission rates for seven months before and seven months after initiation of a respiratory algorithm.SampleRecords of infants were included if they were born >35 weeks' gestation, had documented mild respiratory distress after birth, required <48 hours of noninvasive respiratory support, and had a length of stay less than four days.ResultsNinety-six infants (beforen= 34, aftern= 62) were included. Before implementation of the respiratory algorithm, infants requiring noninvasive respiratory support were admitted to the NICU. Following implementation of the algorithm, NICU admissions for mild respiratory distress significantly decreased (86 percent), despite a concurrent increase in maternal acuity.

PurposeThis study aimed to explore support for mothers and fathers in single-family rooms (SFRs) of a NICU.DesignA qualitative descriptive design was employed.SampleA convenience sample of 15 parents (nine mothers, six fathers) were recruited from a Level III NICU.MethodDuring their infants' hospitalization, each parent recorded their thoughts and feelings regarding support whenever appropriate over a period of 48 hours using Handy Application to Promote Preterm infant happY-life (HAPPY), an android recording application.ResultsParents felt supported when staff facilitated their learning in a collaborative manner, fostered their optimism, and provided situational assistance. Continuity and consistency of care and presence were important characteristics of supportive nursing care. Though SFRs offered privacy for parents to learn and to be with their infants, the design limited parental access to nursing and medical staff, which sometimes prevented parents from receiving adequate support and partaking in decision making concerning their infants' care.
VACTERL Association with Situs Inversus Totalis: A Unique Combination
Authors: Slagle Cara L. , Schulz Elizabeth V. , Annibale David J. 
Published: March 2019

BackgroundVACTERL association is a sporadic, nonrandom series of congenital malformations diagnosed by the presence of three or more of the following: vertebral malformations, anal atresia, cardiac defects, tracheoesophageal fistula, renal malformations, and limb malformations. Situs inversus totalis (SIT) and esophageal malformations are rarely associated. This is the first reported case in North America of VACTERL association with SIT.Implications for PracticeRespiratory distress in the term infant requires full exploration of all possible causes because the etiology may be far more complex than routinely diagnosed respiratory distress syndrome. This particular case demonstrates physical exam findings and supportive imaging that would be observed in infants with VACTERL association and with SIT, highlighting considerations when, rarely, both occur simultaneously.

Pressure-Transient Responses of Fractures With Variable Conductivity and Asymmetric Well Location
Authors: Egya David , Geiger Sebastian , Corbett Patrick W. 
Published: March 2019

Summary
Fractures often influence production in hydrocarbon reservoirs, yet the pressure transients observed in the wells might not show the conventional well-test signatures. In this case, the effect of fractures on production would be misinterpreted or even completely missed. The heterogeneous nature of fractured reservoirs makes them difficult to characterize and develop. In addition, the location of a producer within the fracture network also affects the pressure response; however, conventional well-test analysis assumes that the producer is located in symmetrical fracture networks.
In this paper we investigate the effects of variations in fracture conductivity and location of the producer in the fracture network on the pressure-transient responses. To overcome the limitations of the dual-porosity (DP) model, this study uses a discrete fracture/matrix (DFM) modeling technique and an unstructured-grid reservoir simulator to generate pressure transients in all analyzed fracture networks. Our rigorous and systematic geoengineering work flow enables us to correlate the pressure transients to the known geological features of the simulated reservoir model.
We observed that the simulated pressure transients vary significantly depending on the location of the producer in the fracture network and the properties of the fractures that the producer intercepts. Our findings enable us to interpret some unconventional features of intersecting fractures with variable conductivity. We observed that the behavior of two intersecting fractures, in which the well asymmetrically intercepts a finite-conductivity fracture, can be similar to that of a well intercepting a fracture in a connected fracture network with uniform fracture conductivity. Furthermore, a well intercepting a finite-conductivity fracture in naturally fractured reservoirs (NFRs) with both finite- and infinite-conductivity fractures would yield a DP response (V-shape) that might otherwise be absent if the fracture network is assumed to have uniform conductivity.
Predicting the aircraft take-off noise level
Authors: Faiyetole Ayodele Adekunle , Toyin Ibrahim Taofiq 
Published: March 2019

We propose a model function for aircraft take-off noise prediction with distances radially from a runway. The nonlinear model function reveals four main parameters contributing to the effective strength of aircraft take-off noise over distance. A numerical solution of the model function is used to predict the minimum safe distances for residential locations. We infer that residential locations could not be situated within a 4 km radial distance of an airport to avoid regular exposure to above 45 dBA noise levels at night.

Authors: Sambasivam Dhandayuthapani , Sivanesan Senthilkumar , Sultana Sayeeda , Rajadas Jayakumar 
Published: March 2019

Background:
The structural transition of aggregating Abeta peptides is the key event in
the progression of Alzheimer’s Disease (AD).

Objective:
In the present work, the structural modifications of toxic Aβ25-35 and the scrambled
Aβ35-25 were studied in Trifluoroethanol (TFE) and in aqueous SDS micelles.

Methods:
Using CD spectroscopic investigations, the conformational transition of Aβ25-35 and
Aβ35-25 peptides were determined in different membrane mimicking environments such as TFE and
SDS. An interval scan CD of the peptides on evaporation of TFE was performed. TFE titrations
were carried out to investigate the intrinsic ability of the structural conformations of peptides.

Results:
We show by spectroscopic evidence that Aβ25-35 prefers beta sheet structures upon
increasing TFE concentrations. On the other hand, the non-toxic scrambled Aβ35-25 peptide only
undergoes a transition from random coil to α-helix conformation with increasing TFE. In the
interval scan studies, Aβ25-35 did not show any structural transitions, whereas Aβ35-25 showed
transition from α-helix to β-sheet conformation. In membrane simulating aqueous SDS micelles,
Aβ25-35 showed a transition from random coil to α-helix while Aβ35-25 underwent transition from
random coil to β-sheet conformation.

Conclusion:
Overall, the current results seek new insights into the structural properties of
amyloidogenic and the truncated sequence in membrane mimicking solvents.

Authors: Oberti Luca , Alberta Lucchese , Massimo Petruzzi , Francesco Carinci , Dorina Lauritano 
Published: March 2019

Aim:The clinical management of OLP represents a considerable challenge for the oral physician. The aim of this review is to assess the main intervention used in the management of OLP and the efficacy of every type of treatment.Materials & Methods:We searched and analyzed PubMed database for articles on OLP management. Only randomized controlled trials, comparing an active treatment with placebo, or between different active treatments, were considered in this systematic review. Only patients with symptomatic OLP were included and interventions of all types were considered (topical treatment, systemic drugs, non pharmacological intervention).Results:A total of 25 randomized controlled trials were examined and included in this review. Steroids are the most frequently employed drug in the treatment of OLP and their efficacy and safety are demonstrated. Also calcineurin inhibitors and photo-dynamic therapy are used in different studies for OLP management, with positive results.Conclusion:Topical steroids remain the first-line treatment for symptomatic OLP, however, many different pharmacological and non-pharmacological therapies would represent a valid alternative for its management, but, nowadays they require further investigations.
Assessment of Antibody Interference of Enfuvirtide (T20) Function Shows Assay Dependent Variability
Authors: Smith Michele , Hoffman Jonathon , Sojar Hakimuddin , Aalinkeel Ravikumar , Hsiao Chiu-Bin , Hicar Mark Daniel 
Published: March 2019

Background:During HIV infection, fusion of the viral and cellular membranes is dependent on folding of the gp41 trimer into a six-helix bundle. Fusion inhibitors, such as the antiretroviral Enfuvirtide (T20), interfere with the formation of the gp41 six-helix bundle. Recent in vitro studies reveal that the gp41 immunodominant region one targeting antibody 3D6 can block T20 interference, but the clinical and pathophysiologic significance of this finding is unclear.Objective/Method:We have previously characterized a number of antibodies that target conformational epitopes on gp41and herein characterized their ability to interfere with T20 in multiple assays and assess their prevalence in HIV infected subjects.Results:The T20 interference by antibody 3D6 was confirmed in a CHO-HXB2 envelope/ HeLaT4+ cell culture assay. Antibodies that target an immunodominant region one epitope, as well as a gp41 discontinuous epitope, also interfered in this assay, however, not all antibodies that targeted these epitopes showed T20 interference. This response was not due to the direct binding of T20 by the antibodies and could not be replicated utilizing TZM-bl and HL2/3 cells. Notably, serum competition studies on a panel of HIV subjects demonstrate that these conformational targeting antibodies are common in the HIV population.Conclusion:The relatively common nature of antibodies targeting these epitopes, the disparate in vitro results, and lack of reported clinical failures ascribed to such antibodies leads us to conclude that antibody interference of T20 is likely not clinically relevant. However, this warrants continued consideration with the advancement of other fusion inhibitors.
