Abstract
Background and Objective: The consumption of a variety of local herbs and vegetables by man contributes significantly to the improvement of human health in terms of prevention, and/or cure of diseases because plants have long served as a useful and natural source of therapeutic agents. The present study aims at investigating the hematopoietic effect of Nardostachys jatamansi extract (NJE) in albino wistar rats.
Materials and Methods: Twenty four male albino wistar rats were used and divided into 4 groups of 6 animals each. The Group I served as a normal control. The animals of Group II, III and IV were administered orally with aqueous suspension of NJE at the dosage of 100 mg/kg, 200 mg/kg and 400 mg/kg body weight for 15 consecutive days respectively. Then blood was Blood was collected and used for the estimation of Peripheral blood counts (RBC, WBC), haemoglobin, thrombocyte count and Hematocrit was determined at day 0.25 (6 hrs), 0.5 (12 hrs), 1, 2, 5, 10, and 15 days of treatment using automated haematology analyzer. Body weight was also recorded regularly. Statistical Analysis was done by one way ANOVA followed by Bonferroni post hoc test for multiple comparisons using SPSS-16. P value less than 0.05 was considered the level of significance.
Results: All the parameters have shown a significant increase (p = 0.000) in experimental animals except body weight which was increased insignificantly.
Conclusion: Nardostachys jatamansi extract can be attributed to stimulating or protecting hematopoiesis.

Published: April 2020

AbstractThe Rectus Sternalis muscle is a small supernumerary muscle occasionally present in the anterior thoracic wall. During routine dissection for undergraduate medical students we observed a unilateral left sided rectus sternalis present on the anterior thoracic wall.The knowledge about this variation is very useful for morphologists and anatomists. The presence of this muscle may be mistaken by surgeons, radiologists and physicians for tumor on mammogram or during mastectomy which may increase unnecessary burden on their patients.

Published: April 2020

Abstract
Purpose To assess the technical feasibility of percutaneous cholecystostomy (PCC) for acute cholecystitis and formulate an algorithm for PCC.
Materials and methods This is a retrospective study of 35 patients (28 male and 7 female; mean age 60 years) who underwent image-guided PCC from 2008 to 2018 at a tertiary care hospital in South India. Descriptive summary statistics and frequencies were used to assess the technical success and complications.
Results The patients (35/35) presented with fever, abdominal pain, and a few of them had severe sepsis. All these patients were high risk for surgery considering the comorbidities (17/35) and hemodynamic instability (18/35). PCC was performed under ultrasoundguidance, through transhepatic approach, and using single puncture and modified single puncture techniques. The procedure was technically successful in all 35 patients (100%). Two patients (2/35) did not improve clinically after PCC; hence, they were taken up for emergency cholecystectomy with high-risk consent. One patient required a repeat procedure after 3 days due to tube dislodgement. There were no major procedure-related complications.
Conclusion Image-guided PCC can be performed safely and is effective for treating high-risk patients with acute cholecystitis.

Published: April 2020

AbstractChronic pancreatitis (CP) is a chronic progressive process which can cause irreversible damage to both the exocrine and endocrine systems of pancreas. There are various imaging modalities available to evaluate CP of which ultrasonography ( USG), computed tomography (CT), and magnetic resonance imaging (MRI) are most commonly used. USG is used as a screening modality which can show various changes of CP and its complications. However, the information obtained from USG can be limited because of the patient’s body habitus. CT is the workhorse modality which can provide comprehensive information and it is the best modality to detect calcification. MRI, on the other hand, is excellent in demonstrating the pancreatic parenchyma and the ductal system. Alcohol-related pancreatitis is the commonest cause which can show gland atrophy, ductal dilatation, and calcifications. Other less common causes include hereditary and genetic mutation–related pancreatitis. There are other special types of pancreatitis such as autoimmune pancreatitis and groove pancreatitis that have characteristic features on imaging.

AbstractWe conducted a candidate gene association study to test the hypothesis that different gene polymorphisms will be associated with corticosteroid responsiveness and study outcomes among children undergoing congenital heart surgery. This is a prospective observational cohort study at a large, tertiary pediatric cardiac center on children undergoing corrective or palliative congenital heart surgery. A total of 83 children were enrolled. DNA was isolated for three polymorphisms of interest namely N363 (rs56149945) and 9β (rs6198) associated with increased sensitivity to corticosteroids and BclI (rs41423247) associated with decreased sensitivity to corticosteroids. Duration of inotropic use, low cardiac output scores (LCOS), and vasoactive inotrope scores were examined in relation to these three polymorphisms. Using Kaplan–Meier analysis, heterozygous individuals showed longer transcriptional intermediary factor (TIF) compared with wild type for N363 polymorphism (p = 0.05). In multivariable Cox regression, heterozygous alleles for 9β polymorphism showed significantly shorter TIF compared with wild type (hazard ratio = 2.04 [1.08–3.87], p = 0.03). The relationship between lower LCOS scores and alleles groups was significant for 9β heterozygous polymorphism only (1.5 [1–2.2], p = 0.01) in comparison to wild type and homozygous. The presence of heterozygote alleles for the increased corticosteroid sensitivity is associated with longer TIF compared with wild type. Conversely, the presence of heterozygous alleles for the decreased sensitivity to corticosteroids is associated with shorter TIF compared with wild type.

Resumo
Objetivos Investigar os fatores associados à presença de dificuldades alimentares (DAs) na infância, dentre dinâmicas de refeições e práticas parentais.
Métodos Trata-se de um estudo observacional caso-controle. Para o grupo de crianças com queixas de DA, as informações foram retiradas dos prontuários dos pacientes. Para o grupo de crianças sem queixas de DA, a amostragem foi constituída por conveniência (abordagem de famílias nas unidades de pronto atendimento). As entrevistas foram baseadas em questionário estruturado e aplicado na mesma versão para grupo caso e grupo controle.
Resultados O grupo caso foi composto majoritariamente por indivíduos do sexo masculino, enquanto o grupo controle apresentou-se dividido igualmente entre os gêneros. A média de idade foi menor no grupo caso quando comparado ao controle. Verificou-se menor frequência de refeições compartilhadas nas famílias de crianças com DA, especialmente por motivos de estresse, assim como maior ocorrência de refeições mais longas. Observou-se ainda maior risco de desenvolver DA em crianças que realizavam refeições em ambientes inadequados, com menor autonomia, e os cuidadores do grupo caso demonstraram maior chance de não respeitar os sinais de fome da criança, de usarem estratégias como coerção e distração durante as refeições.
Conclusão O estilo autoritário foi associado à presença de DA. Práticas parentais e todos os fatores que envolvem a dinâmica das refeições devem ser avaliados e acompanhados. A dinâmica familiar e de refeições apresentou-se modificada no grupo com DA. Tais comportamentos devem ser avaliados e orientados durante o acompanhamento da queixa alimentar, pois compõem o cenário da queixa.
When was silcrete heat treatment invented in South Africa?

Published: April 2020

AbstractSilcrete heat treatment, along with a suit of other innovations, have been used to argue for an early onset of modern or complex behaviours in Middle Stone Age hominins. This practice was confined to South Africa’s southern and western Cape regions where it was continuously practised since the Still Bay industry. However, the exact moment that this technological advancement occurred still remains unclear. This is partly due to the scarcity of silcrete assemblages dating to the first half of the Middle Stone Age. To determine when silcrete heat treatment began to be well-established, we compare the silcrete assemblages from two archaeological sites situated along the south western coast of South Africa: Hoedjiespunt 1, one of the earliest Middle Stone Age silcrete assemblages dating to 119–130 ka, and Duinefontein 2, one of the latest Early Stone Age assemblages dating to 200–400 ka. Our results suggest that the invention of heat treatment occurred sometime between 130 ka and 200–400 ka, as it is still absent in the earlier assemblage but fully mastered and well-integrated in the recent one. This period corresponds to the time that Homo sapiens became the major hominin species in the southern African subcontinent and it is roughly the time that silcrete use became widespread in the second half of the Cape-coastal Middle Stone Age. This opens interesting new questions on the relation between silcrete use and heat treatment and on why early modern humans spontaneously invented heat treatment when they began using silcrete in the Cape region.

Published: April 2020

Significance
The mechanical reprogramming of fibroblasts, followed by their redifferentiation into rejuvenated fibroblasts in an optimized 3D collagen matrix, made these cells more contractile and more efficient at synthesizing matrix components including laminin, fibronectin, and collagen-IV. Moreover, the rejuvenated fibroblasts obtained through this approach exhibited a decrease in DNA damage. The rejuvenated fibroblasts derived from this method precisely align into tissue architectures, suggesting its potential application as clinical implants in tissue engineering and regenerative medicine.

Published: April 2020

Abstract
In the Philippines, motorized tricycle was subjected to repetitive utilization of brakes due to traffic and road condition. To address the problem regarding the energy loss due to the application of brakes, Kinetic Energy Recovery System or KERS was introduced. KERS serves as the medium to recover and store the momentum of the vehicle. The study was aimed to design a mechanical interface of the kinetic energy recovery system applicable on motorized tricycles. This also aimed to determine the optimal dimensions and material of the flywheel that can maximize the recovery and storage of the lost kinetic energy of tricycles during braking. The triggering mechanism used was a combination of an actuator mechanism and a hand brake lever. The study was able to accomplish and design the appropriate triggering mechanism in order to utilize KERS. The group was able to prove the prototype’s cost- effectiveness of the system with the percent of fuel saved with the application of KERS. It is determined in the study that by utilizing the Flywheel KERS on the motorized tricycle, fuel savings of 2.93%, 4.28% and 5.93% were obtained for uniform velocities of 30 kph, 40 kph and 50 kph, respectively. In this study the group was able to design and fabricate a functional Flywheel Kinetic Energy Recovery system on a Motorized Tricycle.

Published: April 2020

Abstract
As a kind of fluid machinery, the roots vacuum pump is widely used in the metallurgical industry and semiconductor industry. The double-blade roots vacuum pump is widely used in the vacuum system due to its easy manufacture and low cost. The pumping process can be divided into four distinctive processes (i.e. sucking process, transferring process, backlashing process and exhausting process). The characteristics of each process are illustrated sufficiently in this paper. Based on the ideal gas laws, a thermodynamics model of pumping process is established and the influence of gas leakage on the pumping process is taken into consideration. Using this model, quantificational expressions of five gas thermodynamic parameters (volume, mass, pressure, temperature and internal energy) are given. The performance curves are plotted by MATLAB and the pumping characteristics of double-blade roots vacuum pump are discussed at last. This research can provide a theoretical reference on the design of double-blade roots vacuum pump.

Abstract
One of the tools of eye tracking technology is the eyetracker, which recognizes and records the position of the pupils and eye movements. The existing interconnection of saccades, microsaccades, the center of attention with the diameter of the pupils and the psychophysical state of a person gives prerequisites for the use of pupillography in security systems controlled by artificial intelligence. It is important to solve the problem of accurately distinguishing pupil boundaries. An algorithm for pupil extraction using the ImageJ program has been developed.

Published: April 2020

Abstract
Chromium carbides are coated over base metal (Fe) to increase wear and corrosion resistance. The electronic structure and bonding properties for chromium carbide bulk phases (Cr3C2, Cr7C3 and Cr23C6) and Fe-substituted chromium carbides is investigated using Density Functional Theory (DFT). The bonding in these carbides has been interpreted in the form of partial density of states, electron density distribution and Mulliken population method. Cr3C2 exhibits the strongest covalent character while Cr7C3 displays the highest metallicity. Cr3C2 showed the highest stability among the chromium carbide phases. In the Fe-substituted chromium carbides (Cr2FeC2), the site preference of Fe in Cr3C2 system has been reported. In Fe-substituted chromium carbides also show both of metallic and covalent character and Cr2Fe3C2 is found to be the most stable Fe-substituted chromium carbide system.

Abstract
The characteristics of Silicon carbide (SiC) and multi-walled carbon nanotube (MWCNT) nano composite coatings by a Pulse Reverse Electrodeposition (PRE) method is investigated in detail to enhance the microhardness (MH) and corrosion resistance characteristics of AISI 304 stainless steel substrate. The electrodeposition nature, dissolution behavior, surface characteristics are assessed by Scanning Electron Microscopy (SEM) with energy dispersive x-ray (EDX), x-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), Microhardness (MH) Test and Electrochemical studies. The coatings are prepared in the watts type bath using pulse reverse electrodepositions (PRE) method of varying the electrolyte deposition parameters in different combinations. Present results clearly reveal that, there is a drastic improvement in the magnitude of microhardness of coated specimens, silicon carbide (SiC) and multi-walled carbon nanotube (MWCNT) composite coatings yield a maximum hike of 91.6% and 168% respectively. Furthermore, the Nyquist and impedance plots clearly depict that, multi-walled carbon nanotube (MWCNT) exhibits higher corrosion resistance characteristics.
Compression and fracture behavior of leather particulate reinforced polymer composites

Published: April 2020

Abstract
Strategies are suggested for the waste utilization of industrial leather by preparing composites with epoxy and high-density polyethylene (HDPE). The addition of leather improves the average specific compression toughness of epoxy by 29%. The fracture surface analysis suggests the incorporation of leather microparticles leads to a transition of failure mode of epoxy from brittle to ductile. In addition, the dynamic strength of the leather/epoxy composite is found to be 69% higher than that of neat epoxy. However, no significant changes are observed when HDPE is infiltrated with leather. Apart from dispersing the leather particles directly in polymer, a novel strategy is presented here in which leather/HDPE microfibers are prepared and then used to reinforce the epoxy matrix. The specific compression modulus of this composite blend is 8% and 65% higher than epoxy and HDPE, respectively. Fractography is further carried out on the failed specimens to understand the failure mechanism in each composite. A change in the failure mode is observed when epoxy is reinforced either with leather particles or the microfiber. While the failure strength of the microfiber is found to be higher than epoxy, the strength of microfiber/epoxy interface is lower than that of epoxy.
The modal argument improved
Authors: Cutter Brian 
Published: April 2020

AbstractThe modal argument against materialism, in its most standard form, relies on a compatibility thesis to the effect that the physical truths are compatible with the absence of consciousness. I propose an alternative modal argument that relies on an incompatibility thesis: The existence of consciousness is incompatible with the proposition that the physical truths provide (in a sense to be clarified) a complete description of reality. I show that everyone who accepts the premises of the standard modal argument must accept the premises of the revised modal argument, but not vice versa.
Efficient exact inference for dynamical systems with noisy measurements using sequential approximate Bayesian computation
Authors: Schälte Yannik , Hasenauer Jan 
Published: April 2020

Abstract

Motivation
Approximate Bayesian computation (ABC) is an increasingly popular method for likelihood-free parameter inference in systems biology and other fields of research, as it allows analyzing complex stochastic models. However, the introduced approximation error is often not clear. It has been shown that ABC actually gives exact inference under the implicit assumption of a measurement noise model. Noise being common in biological systems, it is intriguing to exploit this insight. But this is difficult in practice, as ABC is in general highly computationally demanding. Thus, the question we want to answer here is how to efficiently account for measurement noise in ABC.

Results
We illustrate exemplarily how ABC yields erroneous parameter estimates when neglecting measurement noise. Then, we discuss practical ways of correctly including the measurement noise in the analysis. We present an efficient adaptive sequential importance sampling-based algorithm applicable to various model types and noise models. We test and compare it on several models, including ordinary and stochastic differential equations, Markov jump processes and stochastically interacting agents, and noise models including normal, Laplace and Poisson noise. We conclude that the proposed algorithm could improve the accuracy of parameter estimates for a broad spectrum of applications.

Availability and implementation
The developed algorithms are made publicly available as part of the open-source python toolbox pyABC (https://github.com/icb-dcm/pyabc).

Keeping Race at the Center of School Discipline Practices and Trauma-Informed Care: An Interprofessional Framework
Authors: Joseph Andrea Asha , Wilcox Serena M , Hnilica Rebecca J , Hansen Mary C 
Published: April 2020

Abstract
Given the unique forms of trauma that some Black and Brown youths are exposed to, and the salience of race and racial bias in discipline decision making, this article proposes that discipline interventions should be both race centered and trauma informed. Using critical race theory (CRT), trauma-informed practice literature, and restorative practice philosophies, this article presents a framework that highlights how schools can incorporate racial equity into mental health practices and discipline decision making with students. Namely, CRT tenets such as the centrality of race and racism, challenging the dominant perspective, valuing experiential knowledge, and the commitment to social justice guide authors’ recommendations on discipline decision making. Using an interprofessional perspective, this framework delineates how school social workers, school psychologists, and school counselors can support their schools to integrate interprofessional, trauma-informed, and race-centered practices into a behavioral intervention. Ultimately, this article provides interpersonal, practice, and structural recommendations that can help practitioners engage in equitable discipline decision making.
