Authors: Grobler Corlé , Van Wyk René , Magau Mpho D. 
Published: April 2019

Orientation: This multiple qualitative case study provides a change leadership framework through augmentation of Kotter’s eight-step change leadership model. This framework provides practical guidelines for the implementation of Broad-Based Black Economic Empowerment (B-BBEE).Research purpose: To establish a transformational change leadership framework for B-BBEE implementation, applying Kotter’s eight-step change leadership model.Motivation for the study: It is not clear to what extent a transformational change leadership framework can be applied for the improved implementation of B-BBEE in South African organisations.Research design, approach and method: This is a multiple qualitative case study with a constructivist philosophy. Sixteen organisations were purposively selected from the Top 100 rated Most Empowered Companies. Five B-BBEE transformation experts were selected for interviewing. The five participants were executives aged between 35 and 50 years: female (4), male (1), black people (2) and white people (3). Deductive thematic analysis was done using pre-defined themes and Kotter’s change leadership steps. Inductive perspectives were applied when new insights were gained.Main findings: The transformational change leadership framework for the implementation of B-BBEE incorporated Kotter’s steps and additional essential elements.Practical/managerial implications: The study proposes that a transformational change leadership framework could be used for implementing successful, sustainable B-BBEE in South Africa.Contribution/value-add: Different elements contributed the B-BBEE transformational change leadership framework, namely: the role of leadership; leaders’ personal commitment, values and beliefs; and support in driving effective transformation. A willing culture seems essential for sustainable climate of change that leads to transformation maturity.

Published: April 2019

Background:
The differential diagnosis of pelvis renalis cancer (PRC) from renal cell cancer (RCC) is difficult. Because of that, in this study, we compared the standardized uptake value (SUV) with positron emission tomography-computed tomography (PET-CT) of the RCC and PRC.

Methods:
Twenty-one patients (12 males, 9 females; age range: 33–74 years; mean age ± standard deviation [SD]: 57.14 ± 17.6) with suspected primary renal cell cancer as Group 1 and 8 patients (6 male, 2 female; age range, 61–81; mean age ± SD, 71.5 ± 5.65) with suspected renal pelvis cancer as Group 2 detected by conventional imaging techniques (CT, magnetic resonance [MR] imaging, ultrasound, intravenous urogram, CT urography, MR urography) underwent fluorine-18-fluorodeoxyglucose (18F-FDG) PET/CT imaging between August 2010 and October 2012.

Results:
Mean age is 57.14 (33–74) years in Group 1 and 71.5 (61–81) years in Group 2, respectively. The mean maximum SUV (SUVmax) value was 4.6 ± 2.1 in RCC group and 16.6 ± 6.9 in PRC group. At the 18-FDG PET/CT scanning, SUVmax value higher in patients with PRC than in the patients with RCC. It was statistically different (P < 0.001).

Conclusion:
We suggested that PET/CT can be used for the differential diagnosis of renal pelvis tumor and RCC. However, further studies with larger patient number are needed to confirm our suggestion. To clarify the mechanisms of underlying these differences, molecular advanced molecular studies are needed.

<p>Las estrategias arquitectónicas se alejan de la relación objetual con el entorno, abandonando la condición de objeto singular posado en el paisaje. Se concentran, por el contrario, a la creación de espacios de vida a partir de una extrusión del suelo y su posterior “excavación”. Al dejar de ser el encuadre del paisaje oceánico una prioridad, sobreviene la necesidad de crear un micromundo que permite entender el paisaje, revelando sus cualidades en la escala humana.</p>

Published: April 2019

Background
Quality of life (QOL) is an important primary care outcome, but the QOL of older adults treated in primary care is understudied in China. This study examined QOL and its associated factors in older adults treated in Chinese primary care.

Methods
A total of 752 older patients (65+ years) were consecutively recruited from 13 primary care centers in Wuhan, China, and interviewed with a standardized questionnaire, concerning socio-demographics, major medical conditions, loneliness, and depression. QOL and depression were measured with the Chinese six-item QOL questionnaire and the shortened Geriatric Depression Scale, respectively. Multiple linear regression was used to identify factors associated with poor QOL.

Results
The average QOL score of primary care older adults was (20.7 ± 2.5), significantly lower than that of the Chinese general population. Factors significantly associated with poor QOL of Chinese primary care older adults included engaging in manual labor before older adulthood (unstandardized coefficient [β]: −0.702, P < 0.001), no living adult children (β: −1.720, P = 0.001), physical inactivity (β: −0.696, P < 0.001), having ≥ four major medical conditions (β: −1.813, P < 0.001), hearing problem (β: −1.004, P = 0.017), depression (β: −1.153, P < 0.001), and loneliness (β: −1.396, P < 0.001).

Conclusions
Older adults treated in Chinese primary care have poorer QOL than the general population. Addressing psychosocial problems at Chinese primary care settings could be helpful in improving QOL in Chinese older adults.

Published: April 2019

Aims: The aim of this study is to estimate the total carbon sequested by some Woody plant Species in Makurdi zoological garden and its contribution to climate change.
Study Design: Random sample plots of 100 m × 100 m were located in the field using a Garmin GPS and simple allometric procedures using standard carbon inventory principles and techniques that are based on data collection and analysis of carbon accumulating in the above-ground biomass, below-ground biomass, and soil carbon using verifiable modern methods were adopted.
Place and Duration of Study: Field experiment was carried out at the Makurdi zoological garden, Benue State, Nigeria between September and October 2018.
Methodology: The non-destructive method was used with the view to determine the above ground biomass (AGB), below ground biomass (BGB), Estimate the above ground carbon (AGC), below ground carbon (BGC), Total Carbon Content (TCC) and also to estimate the Above ground C02 and below ground C02 and the total C02 Sequestered in the study area.
Results: A total number of 27 species of trees belonging to 16 different families were found in randomly selected sample plots. The diameter at breast height (DBH) was measured at 1.3 m from ground level with a good measuring tape while heights of plants were measured using haga altimeter. The result showed that a total of 3331.05 ton/ha of C02 was estimated to have been sequestered using the non-destructive field measurement.
Conclusion: Total average standing biomass of various tree species was calculated to be 907.6395 tons/ha whereas the total average carbon sequestered was 302.6918 tons/ha. Carbon sequestration capacity of trees increased as the age of trees increases. Therefore it can be concluded that the older trees have higher carbon content than younger trees hence, they are reservoirs of carbon.

Introduction: Diabetes being one of the commonest non-communicable diseases worldwide has no cure. The available hypoglycemic drugs are costly, and have associated long-term side effects. M. oleifera leaves are used in many countries in Africa and Asia to treat diabetes. The study compared the hyperglycemic control of M. oleifera leaves aqueous extract and Glibenclamide tablet in alloxan monohydrate induced diabetic rats.
Methods: Twenty-four female Wistar albino rats, made diabetic using alloxan monohydrate, received either M. oleifera extract, glibenclamide or distilled water were delivered intragastric. The mean body weight and mean fasting blood sugar were measured over a period of 28 days.
Results: Rats that received distilled water had a mean fasting blood sugar of 329.3+44.9 mg/dl at the beginning, which increased to 448.0+189.9 mg/dl on day 14; all the rats were dead by day 21. The rats that received M. oleifera had blood sugar 443.4+134.7 mg/dl at the beginning, dropped to 166.5+162.79 mg/dl by day 14, and to 88.7+41.0 mg/dl by day 28. Rats that received glibenclamide had blood sugar 517.6+139.3mg/dl at the beginning, dropped to 209.0+201.9 mg/dl on day 14, and to 89.7+42.85 mg/dl on day 28. The blood sugar of the M. oleifera and glibenclamide groups reached normal level by day 21 and remained within the normal range up to day 28. Conclusion: Moringa oleifera leaves aqueous extract has similar pattern to glibenclamide tablet in causing hypoglycemia to alloxan monohydrate induced diabetic rats.
Cobalt(II)‐Catalyzed [5+2] C−H Annulation of o‐Arylanilines with Alkynes: An Expedient Route to Dibenzo‐[b,d]azepines

Published: April 2019

AbstractThe first example of CoCl2‐catalyzed formal [5+2] oxidative annulation of o‐arylanilines with alkynes was developed, giving access to various important imine‐containing dibenzo‐[b,d]azepine scaffolds through sequential C−C/C−N bond formation. The reaction employs catalytic amount of manganese and oxygen as cooxidants, and features a broad substrate scope. Preliminary mechanistic studies suggested that C−H activation is involved in the rate‐determining step. Moreover, both internal and terminal alkynes are well tolerated in this transformation. Besides, a regioselective migratory insertion was observed when using terminal alkynes as substrates.magnified image

AbstractSpinel‐type LiMn2O4 cathode materials commonly suffer from manganese dissolution due to the severe interfacial side reactions especially at elevated temperature. Here, a 3D hollow fusiform LiMn2O4 cathode material is reported with preferentially exposed stable {111} facets and seamless outer structure, which is clearly confirmed by microfocused ion beam scanning electron microscopy, high‐resolution transmission electron microscopy as well as scanning transmission electron microscopy with atomic resolution. Owing to the optimal geometrical structure design and the preferentially exposed stable {111} facets, the electrode delivers excellent rate capability (107.6 mAh g−1 at 10 C), remarkable cycling stability (83.3% capacity retention after 1000 cycles at 1 C), and outstanding high‐temperature performance. Together with the analyses of electrochemical behaviors, in situ X‐ray diffraction at different temperatures, and ex situ X‐ray photoelectron spectra, the underlying working mechanism for suppressing manganese dissolution is clearly articulated. These findings could provide significant guidelines for precisely designing highly stable cathode materials for LIBs.

AbstractX‐linked dominant chondrodysplasia punctata (Conradi–Hunermann–Happle syndrome, CDPX2) caused by mutations in the emopamil‐binding protein (EBP) gene and congenital hemidysplasia with ichthyosiform nevus and limb defects (CHILD) syndrome caused by mutation in the NAD(P)H steroid dehydrogenase‐like (NSDHL) gene are rare, typically male lethal disorders. CDPX2 skin lesions are characterized by transient severe congenital ichthyosis following the lines of Blaschko, whereas in CHILD syndrome, the lesions show striking lateralization. Here, we report a male CDPX2 patient with postzygotic mosaicism of the EBP gene presenting with lateralized skin lesions with strict midline demarcation as seen in CHILD syndrome (although this diagnosis was ruled out based on analysis of NSDHL), but also partly distributed along Blaschko's lines as seen in CDPX2. The lesions resolved within a few months, but the patient had other abnormalities, including shortening of the limbs, epiphyseal stippling, and forearm asymmetry; he also had problems with respiration and feeding in the first 4 years after birth. Kyphoscoliosis with dysplastic vertebral bodies progressed rapidly and required posterior spinal fusion surgery at 6 years old. These findings provide insights into the pathophysiology of CDPX2 and the mechanism of asymmetric lesion formation during development.
A new model for estimating the gas compressibility factor using Group Method of Data Handling algorithm (case study)
Authors: Shariaty Soroush , Khorsand Movaghar Mohammad Reza , Vatandoost Ashkan 
Published: April 2019

AbstractIt is crucial to accurately determine the gas compressibility factor (z factor) in chemical and petroleum engineering calculations. Empirical correlations are one of the most rapid and convenient methods of determining the gas compressibility factor. Most of correlations have been developed based on data from Standing–Katz chart, where for high‐pressure conditions (P > 3,000 Psia), solely the data of pure methane was adopted and finally plotted. Therefore, the performance of these correlations would deteriorate for pressurized gas reservoirs. This study intends to use the adopted data of Iranian gas reservoirs (as the second largest source) to develop an empirical correlation concerning with pressurized gas reservoirs. To this end, the correlation was presented based on corresponding states model through the robust group method of data handling algorithm. In comparison with foregone studies, results suggested improvements in prediction of gas compressibility factor with the proposed correlation by up to 9% of average absolute percentage relative error, yielding the error of 1.46% against real data.

The World Health Organization Disability Assessment Schedule II (WHODAS‐II) is one of the most widely used generic assessments for measuring disability levels in both clinical and nonclinical populations, with sound psychometrics that is also aligned with the International Classification of Functioning framework. However, its psychometric properties have not been explored extensively in individuals with autism spectrum disorder (ASD). This study examined the psychometric properties of the 36‐item and 12‐item Self‐Report WHODAS‐II from 109 individuals diagnosed with ASD and without intellectual disability (IQ ≥ 70). Participants were consecutively recruited from the Brain and Mind Centre in New South Wales, Australia. The WHODAS‐II showed adequate internal consistency for all domain scores (α = 0.78–0.97 for 36‐item) and for the summary scale (α = 0.95 for 36‐item; 0.86 for 12‐item). All items also exhibited satisfactory correlations with their respective domain (r = 0.39–0.94 for 36‐item) and summary scores (r = 0.42–0.71 for 36‐item; 0.42–0.67 for 12‐item), except item 4.5 “sexual activity” from the 36‐item WHODAS‐II (r = 0.19). Concurrent validity was shown by moderate correlations between similar constructs across the WHODAS‐II and the World Health Organization Quality of Life BREF (Ps < 0.05). The second‐order 7‐factor model showed the best fit for the 36‐item WHODAS‐II, while the second‐order 6‐factor model demonstrated an acceptable fit for the 12‐item WHODAS‐II. The model fit could be improved with some modifications. The Schmid‐Leiman transformation further confirmed the appropriateness of the second‐order factor structure. Overall, the results indicated that the WHODAS‐II is a viable generic self‐report measure for disability in autistic individuals without ID. Autism Res 2019, 12: 1101–1111. © 2019 International Society for Autism Research, Wiley Periodicals, Inc.Lay SummaryThe majority of autistic people have a disability with a profound or severe limitation in their core activities. However, there is currently limited research identifying reliable and valid self‐report measures for disability in the autistic population. This study examined the psychometric properties of the World Health Organization Disability Assessment Schedule II (WHODAS‐II) from 109 autistic individuals without intellectual disability. Our results suggest that the WHODAS‐II is a viable generic self‐report measure for disability in autistic individuals.
Narrative congruence between populist President Duterte and the Filipino public: Shifting global alliances from the United States to China

AbstractThis research examines what happened when the populist Philippine President Rodrigo Duterte reversed his country's global alliance, switching loyalties away from the United States towards China. We use the lens of narrative congruence, to see if political storylines of a populist president are accompanied by similar shifts in storylines among his followers. Our data corpus consists of text from Duterte's speeches and from comments on partisan Facebook pages, representing supporters and opponents of the president. We time‐bound our data corpus to text produced around the time President Duterte announced his realignment towards China. We use text mining and network analysis to identify overlaps among words used by the different social actors. Our findings show that when Duterte switched alliances, Facebookers—regardless of partisanship—accepted this alliance shift. However, our results likewise reveal an imperfect congruence. Duterte's followers move on to a story criticizing Duterte's domestic political enemies, whereas anti‐Duterte Facebookers talk about monetary deals and drug issues in the Philippines' newfound friendship with China. We discuss our findings in the light of a psychology of populism, the use of a discursive social networks approach to study macropsychological phenomena, and discursive resistance in a populist state.

AbstractCervical cancer (CC) is the fourth leading cause of cancer‐related death in women worldwide. There is an urgent need to find novel targets for the treatment of CC. Recently, microRNA have emerged as critical factors in tumorigenesis. In this study, we aimed to investigate the mechanism of miR‐641 on the migration and invasion of CC cells. In silico analysis revealed putative interaction between miR‐641 and phosphatase and tensin homolog (PTEN) RNA/lncRNA tumor suppressor candidate 8 (TUSC8). Hence we evaluated the expression of TUSC8, miR‐641, and PTEN. We found that the expressions of TUSC8 and PTEN were decreased in CC tissues, whereas miR‐641 expression was increased. Inhibition of miR‐641 suppressed the migration and invasion of Hela cells. In addition, TUSC8 and PTEN were upstream and downstream target molecule of miR‐641, respectively. Overexpression of TUSC8 promoted PTEN expression, and suppressed the invasion and migration of Hela cells, whereas miR‐641 mimic treatment changed the effects. These results demonstrated that overexpression of TUSC8 could inhibit the invasion and migration of CC cells by upregulating PTEN via miR‐641.

AbstractThe presence of history of hyperpigmented crust in a patient with a history of adequate hygiene is typical of terra firma‐forme dermatosis. The treatment is the rubbing of the skin with isopropyl alcohol (removal of the hyperpigmented brown crust, confirming the diagnosis). Physicians should be aware because early diagnosis avoid unnecessary treatment.
cis‐On/trans‐Off of DNA Hybridization with Alkylthio‐azobenzene on L‐Threoninol Responding to Visible Light

Published: April 2019

AbstractAn azobenzene modified with a highly branched secondary alkylthio group incorporated into DNA via an L‐threoninol scaffold can serve as a photo‐switch to reversibly control DNA hybridization. In the system reported here, irradiation with visible light at 400 nm causes photo‐isomerization of trans‐azobenzene to cis and 520 nm light causes the switch to the trans form. The DNA duplex is formed when the azobenzene is in the cis form (upon irradiation with 400 nm light) and is dissociated when the azobenzene is in the trans form (upon irradiation with 520 nm light). In our previously reported system, the switch required UV light. Here, visible light was used to induce both isomerizations, and a smooth trans‐to‐cis isomerization was observed below the melting temperature. This new photo‐switch with visible light overcomes one of the limitations for the potential in vivo use of our method. Combining it with the previously reported photo‐switch will allow the construction of elaborate DNA nanomachines.
