Immunopotentiating effects of polysaccharides extracted from cultivated and wild Cistanche deserticola in Xinjiang

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Objective
To compare the immunopotentiating effects of polysaccharides extracted from wild/cultivate Cistanehe deserticola (WCDPS/CCDPS) in Xinjiang.

Methods
ICR mice were subcutaneously injected twice with different doses (low, medium and high) of WCDPS and CCDPS in combination with ovalbumin (OVA). OVA-specific antibody IgG, as well as IgG1 and IgG2a subtypes, was determined by ELISA. OVA-specific lymphocyte proliferation was measured by MTT. Expression of CD4+ T and CD8+ T cells was analyzed by flow cytometry.

Results
Both WCDPS and CCDPS could significantly improve the production of OVA-specific IgG, IgG1 and IgG2a, promote the proliferation of OVA-specific lymphocytes and increase the expression of CD4+ T and CD8+ T cells (all P 0.05). WCDPS and CCDPS had no influence on the body weight of mice after immunization.

Conclusion
WCDSP and CCDPS could significantly enhance the OVA-specific humoral and cellular immune responses with no statistical difference and are characterized by high safety.

fraction of Hb A in the baby at delivery at 34{ weeks suggests that roughly half the circulating blood was donor blood, for the normal proportions of Hb F and Hb A are not altered by haemolytic disease (Ponder and Levine, 1949).This case is the fourth pregnancy on which this pro- cedure has been performed.In the first two the foetus was already hydropic and death occurred within 24 hours of the transfusion.In the third case two transfusions were performed by the described technique at 31 and 33 weeks.Death occurred within a few hours of the second transfusion, and a mildly hydropic foetus was delivered.It is apparent that timely discovery and selection of these cases is critical, and only amniotic-fluid analysis can provide the necessary precision.Amniography can exclude gross ascites, and the persistence of swallowed dye in the foetal gut provides a convenient permanent marker which enables solid viscera to be avoided.There was no sign of trauma to abdominal viscera at post-mortem examination on the first three babies.In the absence of ascites the detection by needle of planes free from resistance to injection of saline has proved a simple method of locating the peritoneal cavity.The prompt introduction of a catheter with generous slack and withdrawal of the needle removes any risk of trauma from foetal or maternal movement or Braxton Hicks contractions.Reports on intraperitoneal transfusions in neonates and infants (Macdougall, 1958; Mollison, 1961; Scopes, 1963) suggest that both the rate of absorption and total proportion absorbed into the circulation are not entirely predictable.In foetal transfusion further uncertainty is added by a lack of knowledge of the combined blood volume of the foetus and placenta, and the possibility of some leakage from the puncture site on withdrawal of the catheter.For these reasons it cannot be expected that the procedure will restore the foetus to normal.The aim of the exercise is simply to arrest deterioration if possible and gain a few extra weeks of gestation so that the skilled paediatric care of severe haemolytic disease is not nullified by gross pre- maturity.
A new species of dustywings (Neuroptera: Coniopterygidae) from mid-Cretaceous Kachin amber

Field: Agricultural and Biological Sciences (Life Sciences)

speciesThe family Coniopterygidae, commonly known as dustywings, occupies a distinctive niche within the Neuroptera, as they are the smallest members of this order (Grimaldi & Engel, 2005; Engel et al., 2018). Characterized by forewing lengths seldom surpassing 5 mm, with a few exceptions (Liu & Lu, 2017), this family has achieved a remarkable speciosity, with approximately 570 extant species scattered across diverse habitats globally (Oswald & Machado, 2018).
CLINICAL CONFERENCE

Field: Medicine (Health Sciences)

Dr. Schulman: The patient I would like to discuss this afternoon demonstrates a problem which is quite common in pediatric practice, namely that of severe and recurrent epistaxis. The patient is a 9-year-old boy who had manifested repeated episodes of epistaxis since the age of 2 years. The nosebleeds occurred most commonly during the night and more frequently during the winter than the summer months. They usually were not associated with trauma although, on occasion, they did follow sneezing. They seemed to occur more frequently when the child had a concurrent upper respiratory infection. In most instances the nosebleeds stopped spontaneously after a few minutes, but on at least three occasions they were so profuse as to require hospital attention and nasal packing. At the age of 3 years, the child was seen by a physician who informed the mother that something was wrong with the child's platelets and that transfusions would be required each time the child had a nosebleed. During the subsequent 2 years the child was admitted to the hospital for transfusion on several occasions. When the child was 4 years of age the mother sought further advice from a hematologist and the patient was completely evaluated from the standpoint of hemorrhagic disease. No abnormality was found. However, the first physician insisted that a platelet defect was present and informed the mother that transfusions were still required with each nosebleed in order to prevent exsanguinating hemorrhage. Oven the succeeding 5-year period the child received numerous transfusions of whole blood, and in recent years with fresh frozen plasma. The nosebleeds had not increased in number or frequency during this period and the child was otherwise clinically well. Two weeks ago the child was brought to the Children's Memorial Hospital for further study. The past history disclosed no evidence of a bleeding tendency apart from the nosebleeds. Specifically there had been no easy bruising, no bleeding following circumcision, or eruption of the teeth, and no development of hematomata after the usual immunization injections. Complete family history was likewise negative for any evidence of an abnormal tendency to bleed.
Using mimicking gestures to improve observational learning from instructional videos

Field: Psychology (Social Sciences)

This study, generated from considerations of embodied cognition, observational learning, and cognitive load theory, investigated the effect of mimicking gestures on learning to play piano tasks. Fifty university students from an Australian University, with two different levels of piano-playing experience, were randomly assigned to one of the two different gesturing conditions in a 2 (gestures vs. no-gestures) × 2 (novice vs. more expertise) design. All groups viewed an animated video presentation of four musical scores being played on a piano with the hand motions visible, accompanied by the sounds of the notes played. Participants in the gesturing condition were required to gesture while watching the presentations, but in the no-gesturing condition, gesturing was prohibited. Test results indicated a significant learning advantage to gesturing with reduced cognitive load. It was also evident that the efficacy of gesturing was influenced by learner expertise and task complexity.
La innovación educativa en la Educación de Adultos como mejora del proceso de enseñanza-aprendizaje

Field: Social Sciences (Social Sciences)

This experience was carried out in adult education centres for basic training and illiterates. The characteristics\nof students (60-year-old women, lower-middle socioeconomic level, from an agricultural area\nand small towns) make it difficult to adapt a teaching-learning process to them which, at the same time\nwill provide significant benefits in the development of their knowledge. Acquisition of knowledge by\nmeans of this methodology is more satisfactory than with other methods and students are more motivated\nbecause they learn to investigate through the scientific method and reach meaningful learning\nthrough their own discovery, using this basic instrumental competence.

Worlds of Labor on Georgetown’s Waterfront: Work, Freedom and the Labor Question in Guyana, c. 1890–1966

Field: Social Sciences (Social Sciences)

Abstract This article examines conflicts over the meaning and organization of work on the waterfront of Georgetown, Guyana. In the Anglophone Caribbean, “free” wage labor was a key component of the post-emancipation civilizing mission. Afro-Caribbean peoples, however, had their own ideas about the place of wage labor in their individual and collective lives. For many freed peoples and their descendants, wage labor was often one “livelihood strategy” among many, and it did not always take priority over other individual needs, or familial and communal concerns. This article investigates how these different understandings of wage labor shaped the multifaceted worlds of Georgetown’s Afro-Guianese waterfront workers. The first part examines the social relations and hierarchies that mediated the organization of work on the waterfront, influenced waterfront workers’ attitude toward wage labor and its relationship to other aspects of their lives, and facilitated episodes of industrial protest, including strikes when Afro-Guianese and Indo-Guianese workers co-operated in defiance of British Guiana’s racialized political economy. The second part focuses more narrowly on the workplace and the colonial authorities’ ongoing search for answers to the labor question. The article contends that decasualization—which complemented the wider post-1945 development and welfare agenda—represented a new iteration of the post-emancipation project to organize Afro-Guianese peoples’ lives around wage labor. Against the backdrop of rising anti-colonial sentiment and the subsequent split within the nationalist movement, the article demonstrates that although the colonial authorities had some success in creating a cohort of regular waterfront workers, decasualization was no panacea for the labor question.
CT assessment of pulmonary sclerosing hemangioma

Field: Medicine (Health Sciences)

Objective To access the value of CT in the diagnosis of pulmonary sclerosing hemangiomas. Methods Fourteen cases of pulmonary sclerosing hemangiomas comfired pathologically were included in this retrospective study. Ten cases underwent conventional CT scan. Dynamic contrast enhanced CT scan was performed in 4 cases. Results Thirteen cases had solitary lesion and one case had multiple lesions. The lesions were demonstrated as well defined round or ovid masses, six with focus of calcification.The air meniscus sign was seen in two patients. Eight masses enhanced significantly after the injection of contrast materials. In dynamic study, the maximum enhanced CT values were (72.8±8.6) Hu. Conclusion Pulmonary sclerosing hemangiomas manifest the features of benign tumor in the non enhanced CT. Dynamic contrast enhanced CT and the sign of air meniscus can be helpful in diagnosing sclerosing hemangioma.
The Effects of Perceived Parental Behaviors, Attitudes, and Substance-Use on Adolescent Attitudes toward and Intent to Use Psychoactive Substances

Field: Psychology (Social Sciences)

The effects of parental behaviors, attitudes, and drug-use as perceived by adolescents on the latter's attitudes toward and intent to use psychoactive substances were studied. Perceived parental rejection, acceptance, and attitudes significantly differentiated between adolescents who reported favorable attitudes toward and high intent to use substances and those who expressed less favorable attitudes. On most parameters, the father's influence was significant, whereas the effect of the mother did not reach significance. Positive and significant relationships were also found between perceived parental rejection, acceptance, and attitudes and adolescent attitudes and intent to use psychoactive substances. No relationships were found between controlling parental behavior and adolescent attitudes and intent to use psychoactive substances. The role of the parents, as well as implications of the findings for prevention are discussed.
Dimension Independent Generalization of DP-SGD for Overparameterized Smooth Convex Optimization

Field: Computer Science (Physical Sciences)

This paper considers the generalization performance of differentially private convex learning. We demonstrate that the convergence analysis of Langevin algorithms can be used to obtain new generalization bounds with differential privacy guarantees for DP-SGD. More specifically, by using some recently obtained dimension-independent convergence results for stochastic Langevin algorithms with convex objective functions, we obtain $O(n^{-1/4})$ privacy guarantees for DP-SGD with the optimal excess generalization error of $\tilde{O}(n^{-1/2})$ for certain classes of overparameterized smooth convex optimization problems. This improves previous DP-SGD results for such problems that contain explicit dimension dependencies, so that the resulting generalization bounds become unsuitable for overparameterized models used in practical applications.
Negative beam displacements from negative-index photonic metamaterials

Field: Physics and Astronomy (Physical Sciences)

It is well known that refraction of light at interfaces leads to a beam displacement for oblique incidence of light onto a slab of material. In ray optics and for homogeneous isotropic materials, the sign of this beam displacement is strictly identical to the sign of the refractive index. Our numerical calculations reveal negative beam displacements from state-of-the-art double-fishnet-type photonic metamaterials. This holds true for the "main" polarization corresponding to a negative phase velocity for normal incidence as well as for the "secondary" polarization with positive phase velocity. To understand and interpret these results, we also present exact analytical calculations for thin metal films showing that, in wave optics, the sign of the beam displacement (i.e., the sign of refraction) is generally not identical to the sign of the refractive index.
Müllerian uterine malignancy associated 1,25-dihydroxyvitamin D mediated hypercalcemia- a rare occurrence

Field: Medicine (Health Sciences)

Hypercalcemia due to malignancy can have several causes. Vitamin D mediated hypercalcemia is rare in solid organ tumors. In this case report, we describe a patient diagnosed with Müllerian uterine malignancy who presented to the hospital exhibiting typical symptoms of hypercalcemia, including fatigue and constipation. Laboratory investigations revealed that the hypercalcemia was primarily driven by elevated levels of 1,25-dihydroxyvitamin D. Despite multiple interventions aimed at reducing the calcium levels, it remained elevated until chemotherapy was administered. This case highlights an unusual presentation of hypercalcemia associated with a solid tumor, specifically a Müllerian uterine malignancy, and underscores the complexities linked to 1,25-dihydroxyvitamin D-induced hypercalcemia.
Synthesis of high temperature resistant BADCy/PES/BMI resin adhesive by solvent-free method and its performance characterization

Field: Materials Science (Physical Sciences)

A series of high temperature resistant adhesives were synthesis from 2,2'-Bis-(4-cyanatophenyl) (BADCy), polyethersulfone (PES) and N, N'-4,4'-diphenylmethane bismaleimide (BMI) by solvent-free method. The effect of BMI content on the curing behavior, thermal, mechanical, fracture morphology, adhesive and thermal aging properties were studied. With the addition of BMI, the curing activation energy of resin increases from 67.44 kJ/mol of BMI-0 to 69.22 kJ/mol of BMI-30. The reason is mainly due to the higher activation energy of BMI self-polymerization. The BADCy/PES/BMI resin has a wider processing window (BMI-20 has the lowest viscosity in the range of 96°–182 °C), and the processing window becomes wider as the BMI content increases. More interestingly, as BMI content increases, resins toughness decreases and lap shear strength at room temperature decreases (from 31.4 MPa of BMI-0 to 20.0 MPa of BMI-30), but the high temperature performance increases as BMI content increases (temperature for 5% weight loss under N2 atmosphere of BADCy/PES/BMI increase from 404 °C of BMI-0 to 413 °C of BMI-30).

Drivers of green supply chain integration and green product innovation: a motivation-opportunity-ability framework and a dynamic capabilities perspective

Field: Business, Management and Accounting (Social Sciences)

Purpose This study provides an integrative model that facilitates green product innovation (GPI) by adopting dynamic capabilities theory and the motivation-opportunity-ability (MOA) framework. Drawing on dynamic capabilities theory, this study emphasizes green supply chain integration (GSCI), consisting of internal and external integration, as a dynamic capability that drives GPI. Moreover, this study analyzes the environmental conditions that benefit the development of dynamic capabilities using the MOA framework and focuses specifically on government support (GS) and market greenness (MG) as precursors to GSCI. Design/methodology/approach Survey data were collected from 300 Chinese manufacturing firms. The proposed hypotheses were tested using hierarchical multiple regression analysis. Findings The regression analysis reveals that (1) GS and MG positively affect both internal and external integration and (2) internal and external integration positively affect GPI. Originality/value In explicating a model of GPI, this study extends the theoretical lens of dynamic capabilities beyond the intraorganizational level to the supply chain level. Moreover, this study enhances the understanding of dynamic capability development by considering the environmental conditions that represent motivation- and opportunity-based drivers of GSCI.

Trends and Trajectories in the Software Industry: implications for the future of work

Field: Computer Science (Physical Sciences)

Abstract In this study, we explore prominent contemporary technology trajectories in the software industry and how they are expected to influence the work in the software industry. Consequently, we build on cultural lag theory to analyze how technological changes affect work in software development. We present the results from a series of expert interviews that were analyzed using the Gioia method. Moreover, we identify a set of technology trends pertinent to software development from which we derive four main changes affecting the future of work in software development: (1) a shift toward scalable solutions, (2) increased emphasis on data, (3) convergence of IT and non-IT industries, and (4) the cloud as the dominant computing paradigm. Accordingly, this study contains insights into how technology (as an element of material culture) influences non-material culture, as exemplified by the work involved in software development.
Robust Semisupervised Graph Classifier Learning With Negative Edge Weights

Field: Computer Science (Physical Sciences)

In a semisupervised learning scenario, (possibly noisy) partially observed labels are used as input to train a classifier in order to assign labels to unclassified samples. In this paper, we construct a complete graph-based binary classifier given only samples' feature vectors and partial labels. Specifically, we first build appropriate similarity graphs with positive and negative edge weights connecting all samples based on internode feature distances. By viewing a binary classifier as a piecewise constant graph signal, we cast classifier learning as a signal restoration problem via a classical maximum aposteriori (MAP) formulation. One unfortunate consequence of negative edge weights is that the graph Laplacian matrix L can be indefinite, and previously proposed graph-signal smoothness prior xTLx for candidate signal x can lead to pathological solutions. In response, we derive a minimum-norm perturbation matrix Δ that preserves L's eigenstructure-based on a fast lower-bound computation of L's smallest negative eigenvalue via a novel application of the Haynsworth inertia additivity formula-so that L + Δ is positive semidefinite, resulting in a stable signal prior. Further, instead of forcing a hard binary decision for each sample, we define the notion of generalized smoothness on graphs that promotes ambiguity in the classifier signal. Finally, we propose an algorithm based on iterative reweighted least squares that solves the posed MAP problem efficiently. Extensive simulation results show that our proposed algorithm outperforms both SVM variants and previous graph-based classifiers using positive-edge graphs noticeably.
Shakespeare, Montaigne, and the Idea of Savagery

Field: Arts and Humanities (Social Sciences)

The European response to new geographical and ethnographic information in Renaissance travel literature is explored. Using Shakespeare's The Tempest and Montaigne's essays, the paper also examines depictions of the savage as an individual and savagery as a social form in order to compare artistic to more avowedly empirical representations. The views of the dramatist and the essayist are related to the modern anthropological perspective
