AbstractThe aim of this study was quantitative comparison between 68Ga-Gallgas positron emission tomography (PET) and 99mTc-Technegas single photon emission computed tomography (SPECT) for lung ventilation function assessment in patients with moderate-to-severe obstructive pulmonary disease and to identify image-derived texture features correlating to the physiologic parameters. Five patients with moderate-to-severe chronic obstructive pulmonary disease with PET and SPECT lung ventilation scans were selected for this study. Threshold-based segmentations were used to compare ventilated regions between both imaging techniques. Histograms of both scans were compared to reveal main differences in distributions of radiotracers. Volumes of segmentation as well as 50 textural features measured in the pulmonary region were correlated to the forced expiratory volume in 1 s (FEV1) as the relevant physiological variable. A better peripheral distribution of the radiotracer was observed in PET scans for three out of five patients. A segmentation threshold of 27% and 31% for normalized scans, for PET and SPECT respectively, was found optimal for volume correlation with FEV1. A high correlation (Pearson correlation coefficient >0.9) was found between 16 texture features measured from SPECT and 7 features measured from PET and FEV1. Quantitative measurements revealed different tracer distribution in both techniques. These results suggest that tracer distribution patterns may depend on the cause of the pulmonary obstruction. We found several texture features measured from SPECT to correlate to FEV1.

AbstractSubcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare and poorly differentiated type of cutaneous T-cell lymphoma. In this variant, the lymphoma cells infiltrate preferentially into the subcutaneous adipose tissue. It is an indolent type of non-Hodgkin's lymphoma and can be mistaken for panniculitis. Here, we describe the case of a 59-year-old female patient who presented with altered skin pigmentation with diffuse plaque-like patches in the skin around the thighs and legs. A skin biopsy revealed subcutaneous lobular panniculitis composed of lymphocytes, epithelioid histiocytes, and occasional giant cells admixed with atypical lymphoid cells, which were suggestive of cutaneous lymphoma. Immunohistochemistry showed CD3 positive, CD20 negative, CD8 positive, CD4 occasional cells positive, CD56 negative, and CD5 few cells positive, confirming the diagnosis of SPTCL. Therefore, cases with atypical and nonresolving dermatological lesions should raise a suspicion of SPTCL as diagnosis against other benign conditions.
Metastatic large cell neuroendocrine carcinoma of larynx: Individualizing tumor biology by dual tracer positron emission tomography/computed tomography (68Ga-DOTATATE and 18F-fluorodeoxyglucose) molecular imaging and disease stabilization following 177Lu-DOTATATE peptide receptor radionuclide therapy after initial progression on chemoradiotherapy
Authors: Jadhav Sonali , Basu Sandip 
Published: April 2019

AbstractDebate exists on the disease biology and course of primary large cell neuroendocrine carcinoma (LCNEC) of larynx, being classified as a variant of atypical carcinoid by the World Health Organisation-2005 classification, while literature of its aggressive behavior indicating poorly differentiated neuroendocrine carcinoma (akin to pulmonary LCNEC) exists. The utility of dual tracer positron emission tomography/computed tomography (68Ga-DOTATATE and 18F-fluorodeoxyglucose) in deciphering the dynamic tumor biology and feasibility of peptide receptor radionuclide therapy (PRRT) is illustrated in metastatic LCNEC of epiglottis after disease progression following conventional chemoradiotherapy. Relatively, atypical sites of soft-tissue metastases (subcutaneous tissue of arm, scrotal sac, peritoneum, and lamina of thyroid cartilage) and xiphisternum and disease stabilization following 177Lu-DOTATATE PRRT were other noteworthy unique aspects of this report.

IntroductionThe aim of this randomized controlled experimental study was to evaluate the efficacy of potassium, pH and D-dimer levels in blood, as well as potassium and pH levels in peritoneal lavage fluid, in the early diagnosis of acute mesenteric ischemia.Material and methodsThis study was conducted at the Istanbul University Center of Experimental Medicine after having received approval from the Istanbul University animal testing ethics committee. Male albino Wistar rats (n = 24; 250 to 350 g) were divided into two control groups and two ischemic groups. Levels of potassium, pH, and D-dimer in blood and levels of potassium and pH in peritoneal lavage fluid were analyzed for 1 h and 2 h after the induced acute mesenteric ischemia procedure. The degree of ischemic injury was determined using the histopathological damage score in tissue samples taken from the terminal ileum.ResultsIschemic groups had statistically significant differences in potassium and pH in blood and peritoneal lavage fluid compared to non-ischemic groups (p < 0.05). There was no significant difference between control and ischemic groups in terms of D-dimer and histologic grading results after 1 h (p = 0.132, p = 0.475 respectively), while there was a significant difference between control and ischemic groups after 2 h (p < 0.05).ConclusionsThe levels of potassium, pH, and D-dimer could be useful in daily practice for the early diagnosis of acute mesenteric ischemia.
Examining the Impact of Shipping Charge Fairness on Consumer Satisfaction and Behavior

Published: April 2019

AbstractFirms are increasingly recognizing that consumers' perceptions of price fairness should be considered when making logistics decisions at the firm level. A key element of price fairness is the shipping charges that consumers pay. This is especially critical with respect to online retail shipping charges as they represent a substantial portion of consumers' total cost and are visible to consumers before they place an order. Perceptions of the fairness of these prices are believed to impact online shoppers' selection of a retailer as well as influence subsequent purchase behavior. While large retailers may be able to leverage scale economies in shipping to offer free shipping on many orders, smaller firms may not be able to offer this to consumers. Thus, the general expectations of consumers are an important competitive factor in the environment, especially for the small and medium enterprises that are employers of 70 percent of US workers. This study assesses the impact of shipping charge fairness upon consumer satisfaction, repurchase, and positive word-of-mouth outcomes for a focal firm. Additionally, the moderating influences of shipping charge magnitude and consumer experience are examined. Consumer perceptions of fairness are found to influence satisfaction as well as willingness to repurchase and make positive referrals.

BackgroundThe bushbuck,Tragelaphus scriptus, is a widespread and ecologically diverse ungulate species complex within the spiral-horned antelopes. This species was recently found to consist of two genetically divergent but monophyletic lineages, which are paraphyletic at mitochondrial (mt)DNA owing to an ancient interspecific hybridization event. The Scriptus lineage (T. s. scriptus) inhabits the north-western half of the African continent while Sylvaticus (T. s. sylvaticus) is found in the south-eastern half. Here we test hypotheses of historical demography and adaptation in bushbuck using a higher-resolution framework, with four nuclear (MGF, PRKCI, SPTBN, and THY) and three new mitochondrial markers (cytochrome b, 12S rRNA, and 16S rRNA).MethodsGenealogies were reconstructed for the mitochondrial and nuclear data sets, with the latter dated using fossil calibration points. We also inferred the demographic history of Scriptus and Sylvaticus using coalescent-based methods. To obtain an overview of the origins and ancestral colonisation routes of ancestral bushbuck sequences across geographic space, we conducted discrete Bayesian phylogeographic and statistical dispersal-vicariance analyses on our nuclear DNA data set.ResultsBoth nuclear DNA and mtDNA support previous findings of two genetically divergent Sylvaticus and Scriptus lineages. The three mtDNA loci confirmed 15 of the previously defined haplogroups, including those with convergent phenotypes. However, the nuclear tree showed less phylogenetic resolution at the more derived parts of the genealogy, possibly due to incomplete lineage sorting of the slower evolving nuclear genome. The only exception to this was the montane Menelik’s bushbuck (Sylvaticus) of the Ethiopian highlands, which formed a monophyletic group at three of four nuclear DNA loci. We dated the coalescence of the two lineages to a common ancestor ∼2.54 million years ago. Both marker sets revealed similar demographic histories of constant population size over time. We show that the bushbuck likely originated in East Africa, with Scriptus dispersing to colonise suitable habitats west of the African Rift and Sylvaticus radiating from east of the Rift into southern Africa via a series of mainly vicariance events.DiscussionDespite lower levels of genetic structure at nuclear loci, we confirmed the independent evolution of the Menelik’s bushbuck relative to the phenotypically similar montane bushbuck in East Africa, adding further weight to previous suggestions of convergent evolution within the bushbuck complex. Perhaps the most surprising result of our analysis was that both Scriptus and Sylvaticus populations remained relatively constant throughout the Pleistocene, which is remarkable given that this was a period of major climatic and tectonic change in Africa, and responsible for driving the evolution of much of the continent’s extant large mammalian diversity.
Ability emotional intelligence in young people and older adults with and without depressive symptoms, considering gender and educational level

Background
There is little research on differences in Emotional Intelligence (EI) ability at different stages of adult development. The few published studies tend not to use older adult samples. Previous studies on EI ability and age have shown contradictory results. Our main objective was to evaluate results in EI ability across different stages of adult development, taking into account gender, depressive symptoms, and educational level.

Methods
We interviewed 166 participants (108 women), 66 of whom were aged 18–30 years, 53 aged 31–60 years, and 40 aged 61–76 years. All were either working or enrolled in colleges at the time of the study. The assessment tools used were the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), a test that assesses performance-based EI, and the Centre for Epidemiologic Studies-Depression (CES-D) scale, a tool to evaluate depressive symptoms.

Results
Young people, women, and participants with a higher educational level achieved higher scores on the MSCEIT. Additionally, depressive symptomatology was only partially associated with the MSCEIT (i.e., with the using emotions branch). However, a subsequent joint analysis of the independent effects of variables age, gender, educational level, and depressive symptomatology and their interactions on MSCEIT total suggests that only educational level and depressive symptomatology were associated with EI ability, with the direct relationship between age and gender with MSCEIT disappearing. Additionally, our study indicated an interaction effect between age and depressive symptoms, showing that participants in age cohorts 18–30 and 31–60 and without depressive symptoms have a higher EI ability.

Discussion
Our study suggests that the direct effects of age and gender on EI ability across adult development, using a wide age range, can change or disappear when effects of educational level and depressive symptomatology, and their interactions, are controlled for. Our results also suggest that EI ability is a protective factor against depression in some age cohorts. This novel aspect of our study does not appear in the previous literature. However, prospective studies are needed to verify these findings and examine whether other psychological variables could determine the relations between age, gender and EI ability across adult development.

To determine the effect of Organic-based Fortified Foliar Fertilizer (OFF) on the growth and yield of ‘Lakatan’ banana, this study was conducted at the University of Southeastern Philippines, Tagum – Mabini Campus, Mabini Unit, Mampising, Mabini, Compostela Valley Province, from December 2015 to March 2016.
The experiment was laid out in Completely Randomized Design (CRD) with six treatments replicated three times. The treatments were: T1- control; T2- Recommended Rate of NPK fertilizer/ha; T3 - ½ RR of NPK/ha; T4 –Organic-based Fortified Foliar fertilizer (OFF) at 100 ml/16 liters of water; T5 - ½ RR of NPK + OFF; and T6 - RR of NPK + OFF.
Results showed that no significant effects were observed in terms of the plant height at 15, 30, 45 days after application (DAA), pseudostem girth at 15, 30, 45 DAA, and number of hands per bunch. However, significant differences were obtained in the number of leaves, number of fingers per bunch, fruit weight (kg) and yield (tons/ha) of ‘Lakatan’ banana.
The highest number of leaves were obtained in T6 – RR of NPK fertilizer/ha + OFF which is comparable to T5 – ½ RR of NPK fertilizer/ha + OFF. T6 – RR of NPK+ OFF also had the highest number of fingers per hand than the rest of the treatments as much as 21% higher than the control. The fruit weight of T6 – RR of NPK+ OFF has 61% higher than untreated and the yield of 37 tons/ha is higher than the national average yield of 9.4 tons/ha in ‘Lakatan’ banana.

Authors: Azzam Ahmed M. 
Published: April 2019

Objectives: This work was carried out to investigate the efficacy of galvanic vestibular stimulation in improving of gait performance and upright postural stability in hemiplegic cerebral palsy children.
Method: Thirty children were enrolled in this study and randomly assigned into two groups; group A (galvanic vestibular stimulation plus vestibular training program), and group B (vestibular training program only). Stride length and time, walking speed tests and modified Ashworth, pediatric balance scales were used to detect and follow the walking performance and upright postural stability. This measurement was taken before initial treatment and after 12 weeks of treatment. The children parents in both groups A and B were instructed to complete 3 hours of the home routine program.
Results: Data analysis was available on the 30 hemiplegic cerebral palsied children participated in the study. The difference between pre and post-treatment results was significant representative in stride length , time and walking velocity, spasticity changes and pediatric balance scores in study groups while insignificant improvement in control groups.
Conclusion: The combined vestibular training program and trans-mastoidal vestibular galvanic stimulation are suggested in improving walking performance and upright postural stability in a static and dynamic situation. So this selective physiotherapy approach may be used as a strong choice for improving walking and balance abilities in hemiplegic C.P children.

Aim: The aim of this study was to determine the prevalence of GBS serotype distribution in Jos University Teaching Hospital.
Materials and Methodology: This was a hospital based descriptive cross-sectional study of 300 women receiving health care at the Jos University Teaching Hospital between July 2017 and November 2017. Systematic sampling technique was employed in recruiting consenting subjects for this study. High vaginal and anorectal swabs were collected from each subject after obtaining their consent by signing a structured consent form. The identiﬁed Streptococcus agalactiae (GBS) isolates were serotyped using immuLex strep-B antisera from SSI Diagnostica, 2 Herredysvejen, DK-3400 Hillerod Demnark to identify the different serotypes. The results obtained were computed using SPSS version 21.
Results: A total of 300 women obtaining health care in Jos University Teaching Hospital (JUTH) were enrolled in this study between the months of July, 2017 and November, 2017. In all, vaginal and anorectal swabs were taken from 200 pregnant women and 100 non-pregnant women. The age range of the study population was between 16 years to 48 years with a mean age of 31.9 year (SD ± 6.6). The prevalence rate among the study population was 6.3%. The colonization rate among pregnant and non-pregnant women was 6.5% and 6.0% respectively with no signiﬁcant statistical difference. Serotype Ia was the commonest isolate responsible for 42.1% of the GBS isolates. Serotype III accounted for 31.6% of the isolates, followed by serotype V (15.8%). Serotype II was less common, responsible for only 10.5%.
Conclusion: This study showed that GBS colonization rate among the study population was 6.3%. Approximately, 6.5% and 6.0% prevalence rate were found among pregnant and non-pregnant women respectively. Of all the GBS isolates, serotypes Ia, II, III, and serotype V were isolated with serotype Ia being the most prevalent serotype. This knowledge of serotype distribution will help in instituting serotype speciﬁc GBS vaccines for the prevention of GBS diseases in Jos.
Enhancing Photoacoustic Intensity of Upconversion Nanoparticles by Photoswitchable Azobenzene‐Containing Polymers for Dual NIR‐II and Photoacoustic Imaging In Vivo

Published: April 2019

AbstractNear‐infrared photoacoustic (PA) imaging is developing rapidly as an alternative to optical imaging and promises benefits in terms of deeper tissue penetration and higher spatial resolution. This paper proposes a strategy to enhance the PA intensity of upconverted nanoparticles (UCNPs) by functionalized photoswitchable azobenzene‐containing poly (acrylic acid) (UCNPs@PAA‐Azo) to yield a PA signal that is up to six times higher than that of UCNPs without a decay in NIR‐II emission. The mechanism of enhanced photoacoustic activity of the UCNPs@PAA‐Azo can be attributed to the decay of UV and blue light as well as vibrations of the azobenzene group. This technology delivers high resolution of the hind limb vasculature using dual NIR‐II and PA imaging. Using this nanoprobe, NIR‐II imaging provides real‐time means for the precise resection of the lymph node (LN) during surgery, where PA imaging allows for quicker (up to 30 min) detection of LNs than that through NIR‐II imaging. Combining the advantages of dual NIR‐II and PA modalities allows us to achieve complementary information and improve the accuracy of disease diagnosis. This work is critical to the synthesis of dual NIR‐II and PA modal probes and is utilized in small animals imaging with high resolution and a high signal‐to‐noise ratio.

Published: April 2019

AbstractAtomically thin 2D materials are promising candidates for miniaturized high‐performance optoelectronic devices. This study reports on multilayer MoTe2 photodetectors contacted with asymmetric electrodes based on n‐ and p‐type graphene layers. The asymmetry in the graphene contacts creates a large (Ebi  ∼ 100 kV cm−1) built‐in electric field across the short (l = 15 nm) MoTe2 channel, causing a high and broad (λ = 400–1400 nm) photoresponse even without any externally applied voltage. Spatially resolved photovoltage maps reveal an enhanced photoresponse and larger built‐in electric field in regions of the MoTe2 layer between the two graphene contacts. Furthermore, a fast (∼10 µs) photoresponse is achieved in both the photovoltaic and photoconductive operation modes of the junction. The findings can be extended to other 2D materials and offer prospects for the implementation of asymmetric graphene contacts in future low‐power optoelectronic applications.
