Nutrient resorption from senescing leaves in two Stipa species native to central Argentina

Nutrient resorption from senescing leaves enables plants to conserve and reuse nutrients. As such, it could be expected that plant species adapted to infertile soils have a higher nutrient resorption efficiency (percentage reduction of nutrients between green and senesced leaves) and/or higher nutrient resorption proficiency (absolute reduction of nutrients in senesced leaves) than those adapted to fertile soils. Our objective was to compare nitrogen (N) and phosphorous (P) resorption of two congener grasses that successfully occupy uplands of relatively low fertility (Stipa gynerioides) or lowlands of relatively high fertility (Stipa brachychaeta) in natural grasslands of central Argentina. The two Stipa species did not differ in N and P resorption efficiency, but S. gynerioides had a higher N and P resorption proficiency than S. brachychaeta. As a consequence, leaf-level N and P use efficiency were higher in the species adapted to low fertility conditions than in the species adapted to high fertility conditions. The higher nutrient resorption proficiency of S. gynerioides was also associated with relatively low leaf-litter decomposition and nutrient release rates found in a previous study.
Assessment of the Etiologies and Outcomes of Antenatal Hydronephrosis in Patients at King Abdulaziz University Hospital

Background Antenatal hydronephrosis (ANH) is the most common congenital abnormality. It is often detected during pregnancy through an antenatal ultrasound (US) examination. This condition is defined as the dilatation of the renal pelvis and/or calyces in neonates. Little is known about ANH and its associated etiology and outcomes, especially in the Middle East. This study aims to determine the outcome of patients diagnosed with ANH between 2011 and 2017. Methods The current study was a retrospective analysis of data collected from the medical records of 64 ANH patients (45 male, 19 female). We collected data regarding the demographic characteristics, fetal parameters, laboratory and radiological parameters, and medical and surgical interventions. Moreover, based on radiological reports patients were classified into one of the following two groups: good prognosis, including patients with improved or resolved ANH and poor prognosis, including patients with progressing ANH and associated complications such as parenchymal scarring, chronic kidney disease complicated by secondary hypertension. Results Overall, 48.4% of patients exhibited good prognosis, whereas 51.6% exhibited poor prognosis. Among the 64 patients, 53.1% of patients exhibited unilateral ANH, and 46.9% exhibited bilateral ANH. Also, unilateral ANH and bilateral ANH had good prognoses in 41.2% and 56.7%, respectively, while unilateral and bilateral ANH had poor prognosis in 58.8% and 43.3%, respectively. Conclusions Additional prophylactic measures should be taken to avoid complications, such as urinary tract infection (UTI), as our study found that patients who have ANH are more prone to develop UTI. Patients with several ANH comorbidities are associated with poor prognosis.
Professionals’ Identification Within and Across Science, Technology, Engineering, and Mathematics (STEM) Fields

Professional identity, for many, is a substantial component of their career choices and development. In this study, we utilized data from an online survey completed by 1,867 participants living across the United States to consider the extent to which an individual working in science, technology, engineering, and/or mathematics (STEM) field identifies with each discipline, and how this may be associated with recognition, competence, and sense of belonging. Results from structural equation modeling indicated that participants’ STEM field had a positive, direct impact on their discipline-specific identity but a negative, direct impact on other discipline identities. Furthermore, recognition and competence had significant direct and indirect effects on participants’ STEM identity, which was not consistent by STEM field. Alternatively, sense of belonging and self-identifying as a woman had limited effects in our model. Our findings raise questions as to the possibility (or not) of STEM as an interdisciplinary identity for professionals with a career in STEM.
Corporate Social Responsibility and the Market Reaction to Negative Events: Evidence from Inadvertent and Fraudulent Restatement Announcements

We advance a theory asserting that CSR performance may exacerbate, not necessarily moderate, a company's negative stock price response to negative events. In testing this theory, we hypothesize and find that CSR performance alleviates (magnifies) the immediate negative stock price response to inadvertent (fraudulent) restatement announcements, and that these findings are robust to specifications that consider alternative CSR measures and a multitude of control variables shown by prior research to have explanatory power for the cross-sectional variation in stock returns. Overall, using restatement announcements as a channel through which CSR performance may affect company value, we show, in contrast to prior research, that depending on management conduct leading to the restatement, a company's CSR performance may destroy, not necessarily enhance, firm value. Our findings may, thus, inform researchers, market participants, and regulators. Data Availability: The data used in this study are publicly available from sources indicated in the text.
Energy management education and occupation-related outcomes in adults with chronic diseases: A scoping review

Introduction Fatigue is a pervasive symptom of chronic disease that often interferes with occupational performance. Our objective was to describe what is known about energy management education and occupation-related outcomes in adults with chronic diseases. Methods Seven electronic databases were searched for relevant literature published before August 2019. Eligible articles were full-text, available in English, and studied energy management education in adults with a chronic disease. The first author assessed article eligibility with validation from a second reviewer, extracted characteristics of included studies, and described them using descriptive statistics. A narrative synthesis of findings was conducted for each chronic disease population. Results Forty-four studies addressed eight different chronic disease populations. The most common program delivery format was face-to-face in a group setting (42%), 39% of programs were informed by a learning theory, and their median cumulative length was 8 hours. Positive outcomes were associated with a specific, group-based energy management program in people with multiple sclerosis. The evidence on other energy management programs and in other chronic disease populations was more limited and inconclusive. Conclusions Further research is needed to understand the impact of energy management education in chronic disease populations beyond multiple sclerosis, and its impact on occupational performance.
Repeat Sampling and Coliform Bacteria Detection Rates in New Jersey Domestic Wells

In compliance with the New Jersey Private Well Testing Act, 78,546 wells (93,787 samples, including samples from 13,290 wells that were analyzed more than once) were analyzed for total coliform (TC) bacteria by one or more of 39 laboratories over a 10‐year period. Samples containing TC bacteria were further analyzed for the presence of either fecal coliform or E. coli (FC/EC) bacteria. The large population of wells sampled multiple times permitted a systematic study of the effect of repeat sampling on coliform bacteria detection rates. The detection rate increased with the number of times wells were sampled. In bedrock, TC bacteria were detected in 21% of the population of wells analyzed only once, 33% in the population sampled twice, and 43% in the population sampled three times. It was estimated that TC bacteria would be detected in 90% of all wells if each well was analyzed 10 times. For FC/EC bacteria, it was estimated that 21 and 68 samples, respectively, would be required to reach the 50% and 90% population detection rates. In the Coastal Plain (CP), many more samples would be required to achieve the same estimated population detection rates. The population detection rate estimates were also dependent on the type of method used, the pH of the well water, and the geologic formation in which wells were located. A single sample was not sufficient to detect coliform bacteria when present in well water.
ELECTROCARDIOGRAPHIC PROFILE OF CAPTIVE MARBLED WATER MONITOR LIZARD (Varanus marmoratus, Weigmann, 1834)

Electrocardiography is a very useful procedure for examination of cardiac disorders in animals. However, very few electrocardiographic (ECG) studies have been conducted on reptiles. ECG examination was conducted to obtain the baseline values of 14 captive marbled water monitor lizards (Varanus marmoratus) at a wildlife facility. The ECG values of the monitor lizards were compared according to gender (ten male and four female), length (nine small and five large) and weight (nine <2 kg and five 2 kg and above). Results of the study determined that the length of the animal positively affected the QRS segment. Gender and weight have no significant effect on the electrocardiographic parameters of the monitor lizards. The ECG profile obtained in the study can be used as a reference for examination of cardiovascular disorders in marbled water monitor lizards.

Soil–climate contribution to DNDC model uncertainty in simulating biomass accumulation under urban vegetable production on a Petroplinthic Cambisol in Tamale, Ghana

Crop yield simulation using the Denitrification–Decomposition (DNDC) model can help to understand key bottlenecks for improved nitrogen (N) use efficiency and estimate greenhouse gas (GHG) emissions in West African urban vegetable production. The DNDC model was successfully calibrated using high-resolution weather records, information on management practices and soils, and measured biomass accumulation and N uptake by amaranth (Amaranthus L.), jute mallow (Corchorus olitorius L.), lettuce (Lactuca sativa L.), and roselle (Hibiscus sabdariffa L.) for different input intensities (May 2014–November 2015) in urban vegetable production of Tamale (N-Ghana, West Africa). The root mean square error (RMSE) and relative error (E) values fell within the confidence interval (a 5%) of the measurements, and there was a high correlation (0.91 to 0.98) between measurements and predictions. However, the analysis of uncertainty and factor importance indicated that soil properties (pH, SOC, and clay content) and weather (precipitation) variability contributed highly to yield uncertainty of vegetable biomass.
Nutritional Status of Children with Biliary Atresia and the Role of Portoenterostomy to Improve Nutrition

Background: Nutritional depletion and growth stunting are present in patients with biliary atresia; “normal” nutrient and vitamin supplementation fail to correct these deficiencies. Children with this condition form the largest group for possible liver transplantation in the future; hence, stress should be laid on close attention to their nutrition. Methods: Twenty-five patients with biliary atresia as cases and 25 age-matched children as controls were enrolled in the study from November 2010 to June 2012. Preoperatively, patients underwent standard investigations and anthropometric measurement (weight, height, and head circumference) assessment. Nutritional status (assessed with standard growth chart) was compared with control population, and children were divided into poor nutritional status and good nutritional status. Kasai's portoenterostomy was performed in all patients, and comparison was done between preoperative nutritional status with postoperative status of children and also between hepatic iminodiacetic acid (HIDA) scan-positive (patent bilioenteric pathway) children with HIDA scan-negative children. Postoperatively, after 12 weeks, the same anthropometric measurements were taken again, growth velocity (GV) was assessed, and children were divided into poor, average, and good GV. Results: Nutritional status of children with biliary atresia was significantly poor than that of control group. Postoperatively, children had better nutritional status than preoperative nutritional status, especially in HIDA scan-positive children. GV was also significantly better in those children in whom postoperative HIDA scan was positive. Conclusion: Children with biliary atresia have poor nutritional status in comparison to normal population and require multifaceted approach to achieve adequate nutrition. Establishment of a patent bilioenteric pathway in these children improves their nutritional status and GV.
Resveratrol Nanoparticles: A Promising Therapeutic Advancement over Native Resveratrol

The importance of fruit-derived resveratrol (RES) in the treatment of various diseases has been discussed in various research publications. Those research findings have indicated the ability of the molecule as therapeutic in the context of in vitro and in vivo conditions. Mostly, the application of RES in in vivo conditions, encapsulation processes have been carried out using various nanoparticles that are made of biocompatible biomaterials, which are easily digested or metabolized, and RES is absorbed effectively. These biomaterials are non-toxic and are safe to be used as components in the biotherapeutics. They are made from naturally available by-products of food materials like zein or corn or components of the physiological system as with lipids. The versatility of the RES nanoparticles in their different materials, working range sizes, specificity in their targeting in various human diseases, and the mechanisms associated with them are discussed in this review.
Improving instructional practice through peer observation and feedback: A review of the literature

The Every Student Succeeds Act provides an opportunity for policymakers and researchers to revisit what is known about effective teacher evaluation practices to make better-informed decisions moving forward. Principals—responsible for implementing new teacher evaluation reforms and accommodating the demands to spend more time observing and providing feedback to teachers—are overworked. They have little time to provide high-quality feedback, and may lack important content-based expertise. With these considerations in mind, we explore the role of peer observation and feedback as a vehicle to move beyond high-stakes evaluation and re-center efforts on instructional improvement. Our systematic review of extant literature ( n = 38 documents, 92% peer-reviewed empirical articles) indicates that peer observation and feedback is a promising practice for instructional improvement, but one that lacks sufficient evidence. Policy, thus, can encourage innovation and research around this practice so that peer observation and feedback models can be piloted and the most effective established, as well as strategies to tackle the biggest barriers schools, particularly U.S. schools face in implementing such a practice—time.
Quantification of Some Herbal Distillates’ Methanol to Evaluate a New Diagnostic Kit

Methanol naturally exists in all plant products. In recent years, the consumption of certain kinds of herbal distillates has led to blurred vision, leading to neurotic blindness in Iran. The advanced methods needed for determination of methanol are not available in all parts of poor and developing countries. In this study, we evaluated some herbal distillates’ methanol with a new kit compared to gas chromatography for determining the efficacy of the kit. A gas chromatography apparatus was used to determine methanol concentration of 57 herbal distillates. At the same time, a spectrophotometer device was also used along with a newly designed kit based on the modified chromotropic acid method for the same purpose. All examined samples have different amounts of methanol from 21 to 770 mg/l. The methanol content of all samples was higher than the used kit’s limit of quantification (5 mg/l). The attained results by two used methods were very close together in both minimum (21 and 22 mg/l) and maximum (770 and 690 mg/l) amounts. The comparison of results was shown, and some of available herbal distillates in Iran have enough amounts of methanol to create chronic type of methanol poisoning. Our results suggested that the used kit had suitable efficacy for quantitative determination of herbal distillates’ methanol content. It was proved that the type of the herbal distillate did not affect the kit’s function. The new kit can be easily used with minimal equipment for quality control of herbal distillates in food industry area.

VH gene mutation analysis distinguishes a subgroup of chronic lymphocytic leukemia with low-mutated VH genes and inferior outcome.

Recent studies have shown that the somatic mutation status of the immunoglobulin (Ig) VH genes can divide chronic lymphocytic leukemia (CLL) into two prognostic subsets, since cases with mutated VH genes display superior survival compared to unmutated cases. Biased VH gene usage has also been reported in CLL which may reflect antigen selection.We performed VH gene analysis in 265 CLL cases and confirmed the prognostic impact of the VH mutation status. Preferential VH gene usage was also demonstrated in both the mutated and unmutated subset. Interestingly, CLL cases rearranging one particular VH gene, VH3-21, displayed poor outcome despite that two-thirds showed mutated VH genes. Many of the VH3-21 cases expressed λ light chains, rearranged a Vλ2-14 gene, and had homologous complementarity determining region 3s (CDR3s), implying recognition of a common antigen epitope. We believe that the VH3-21 subset comprises an additional CLL entity.To further explore the B-cell receptors in CLL, we analyzed the VH gene rearrangements and, specifically, the heavy chain CDR3 sequences in 346 CLL cases. We identified six new subgroups with similar HCDR3 features and restricted VL gene usage as in the VH3-21-using group. Our data indicate a limited number of antigen recognition sites in these subgroups and give further evidence for antigen selection in the development of CLL.Different cutoffs have been suggested to distinguish mutated CLL in addition to the 2% cutoff. Using three levels of somatic mutations, i.e. 5%, we divided 323 CLLs into subsets with divergent survival. This division revealed a low-mutated subgroup (2-5%) with inferior outcome that would have been masked using the traditional 2% cutoff. A 1513A/C polymorphism in the P2X7 receptor gene was reported to be more frequent in CLL, but no difference in genotype frequencies was revealed in our 170 CLL cases and 200 controls. However, CLL cases with the 1513AC genotype showed superior survival than 1513AA cases and this was in particular confined to CLL with mutated VH genes. In summary, we could define new prognostic subgroups in CLL using Ig gene rearrangement analysis. This also allowed us to gain insights in the biology and potential role of antigen involvement in the pathogenesis of CLL.
