Abstract

Background
Joint contracture is the major clinical complication in burn patients, especially, the severe burn patients. This study aimed to investigate the number and severity of joint contractures in patients with burns affecting greater than or equal to 50% of the total body surface area (TBSA) undergoing early rehabilitation in a burn intensive care unit (BICU).

Methods
We analyzed burn patients with burns affecting greater than or equal to 50% of the TBSA admitted to a BICU who received early rehabilitation within 7 days post-injury from January 2011 to December 2015. Demographic and medical information was collected. The range of motion (ROM) of different joints was measured 1 month post-admission. Spearman’s correlation coefficient and logistic regression analysis was used to determine predictors of the presence and severity of contractures.

Result
The average affected TBSA of the included burn patients was 67.4%, and the average length of stay in the BICU was 46.2 ± 28.8 days. One hundred and one of 108 burn patients (93.5%) developed at least one joint contracture. The ROM in 67.9% of the affected joints was mildly limited. The majority of contractures in severe burn patients were mild (37.7%) or moderate (33.2%). The wrist was the most commonly affected joint (18.2%), followed by the shoulder, ankle, hip, knee, and elbow. A predictor of the presence of contractures was the length of hospital stay (p = 0.049). The severe contracture was related to the area of full-thickness burns, the strict bed rest time, and the duration of rehabilitation in BICU. The length of rehabilitation stay (days) in patients with moderate contracture is 54.5% longer than that in severe contracture (p = 0.024)

Conclusion
During the long stay in BICU, the length of rehabilitation stay in a BICU could decrease the severity of contractures from severe to moderate in the patients with equal to 50% of the TBSA. Hence, this research reveals the important role of early rehabilitation interventions in severe burn patients.

Animal rights in recent years occupy a significant place among the themes of general national discourse in Ukraine. This year, under the pressure of the public in Ukraine, a law according to the humane attitude towards the "younger brothers" was adopted. But which rights do animals have? And what’s really going on? Legislation on animal protection is not executed even at the level where it is. How often do people who cause animal suffering in my country have the appropriate punishment? The report provides an analysis of the preconditions for reforming the attitude towards animals and their rights. The complexity of solving problem of humane attitude towards animals lies in the fact that it can not be regulated just based on the data of scientific experiments. Evaluation of the ability of animals to consciously feel pain, suffer, think, speak, understand themselves and the events around them is a difficult issue for many people. So, what is Animal Law? And what is Animal Ethic? Do we understand and recognize such concepts in my country?

This article is a case study of the Morris Justice Project (MJP), a participatory action research (PAR) study in a South Bronx neighborhood of New York City (NYC) designed to understand residents’ experiences with and attitudes towards the New York Police Department (NYPD). An illustration of public science, the research was conducted in solidarity with an emerging police reform movement and in response to an ongoing and particularly aggressive set of policing policies that most heavily impacts poor communities and communities of color. The case study describes a set of ongoing participatory, research-action, “sidewalk science” strategies, developed in 42 square blocks of the South Bronx, designed to better understand and challenge the ongoing structural violence of the carceral state. Collaboratively written with members of the Morris Justice collective, we tell our story across three sections that outline the genesis of the project, describe our major commitments, and offers PAR and public science as a possible “intervention” in traditional university practice.
Entrenchment and productivity: The role of input in the code-mixing of a German-English bilingual child

Published: May 2019

AbstractThis paper investigates the role of input in the code-mixing (CM) of a German-English bilingual child between the age of 2;3 until 3;11. Supporting a usage-based approach to linguistic theory, multiword units are shown to play an important role in language acquisition scenarios, both in the input children receive as well as in their own early language production.The current study combines findings from Child-directed-speech (CDS) and children’s output to investigate whether utterance-initial, multiword units in the code-mixing of a German-English bilingual child can be traced back to patterns found in the input.The findings reveal that a large proportion of the child code-mixed (78%) and parental input (59%) data instantiate the selection of multiword units. Additionally, we found that many of the units used by the child (74%) correlate with units in the parental input suggesting that bilingual children construct their code-mixed utterances on the basis of both concrete lexical strings and partially schematic patterns they have heard before.
The effect of adrenaline on the mineral and trace element status in rats
Authors: Shkurashivska Svitlana , Ersteniuk Hanna 
Published: May 2019

AbstractUp until now, changes in biochemical and physiological parameters occurring a long time after stress are not yet elucidated. This is particularly the case for metals, some of which may considerably influence other branches of metabolism, such as bioenergetics and antioxidant defense. The aim of the current study was to investigate changes in levels of minerals (calcium and magnesium) and trace elements (copper and zinc) in erythrocytes and the liver of rats injected once or twice (modeling repeated stress) with adrenaline. The tissues were sampled 0.5 and 24 hours after the injection. A single injection of adrenaline in rats led to a dramatic increase in the levels of zinc (Zn), magnesium (Mg), and calcium (Ca) in their erythrocytes and liver, without a return to the control level (unstressed animals) after 24 hours. The levels of copper (Cu) increased 0.5 hour after a single adrenaline injection in erythrocytes and the liver, but returned to the control level after 24 hours. Double injection of rats with adrenaline led to an increase in the levels of Cu and Zn in their erythrocytes, and Mg in the liver, without a return to the control level after 24 hours. On the other hand, the double injection led to a drastic but transient increase in levels of Mg and Ca in erythrocytes, and Cu, Zn, and Ca in the liver. Thus, injection with adrenaline results in dramatic changes in levels of minerals and trace elements, which do not return to the control level after stress. Low doses of adrenaline lead to more stable changes in levels of essential metals.

Authors: Gupta Shabya , Killamsetty Vinay , Chauhan Monika , Mukherjee Biswajeet 
Published: May 2019

Abstract
A novel circular polarized Hemispherical Dielectric Resonator Antenna (HDRA) has been proposed in this paper. The Circular Polarization (CP) and enhanced gain characteristics of the antenna are attributed to the fractal geometry applied on the HDRA. Probe coupling is used to excite the proposed antenna which resonates at 4.16 GHz and offers an impedance bandwidth of 2.6 GHz (57 %), from 3.3 to 5.9 GHz. The gain and efficiency of the antenna are 6.38 dBi and 93 % respectively at 4.16 GHz. The Proposed DRA is designed using FR-4 material having a dielectric constant (εr
) of 4.3 and dissipation factor (tan δ) of 0.025. The designed Antenna is experimentally verified and offers a close agreement between simulated and measured results. This Antenna offers a 3-dB Axial Ratio (AR) bandwidth of 1.1 GHz from 4.2 to 5.3 GHz.

Published: May 2019

Abstract
The cutting force, the friction coefficient of the rake face, and the flank wear of functional gradient cemented carbide (FGCC) cutting tools prepared by microwave heating and nitriding sintering were tested by turning test and compared with those of a conventional cemented carbide cutting tool. The results show that the cutting force, the friction coefficient of the rake face, and the wear of the GFCC cutting tool are lower than those of the conventional cutting tool with the same composition. Additionally, the effects of cutting speed on cutting force and tool wear were studied. Furthermore, the failure mechanism in the cutting process, the heat distribution of the second derformation zone and the resistant to the generation and extend of tool surface micro-cracks were analyzed. The friction and wear mechanism of the FGCC tool was found to be affected by the gradient distribution of the tool surface composition.

Tidal volume monitoring during initial resuscitation of extremely prematurely born infants
Authors: Hunt Katie A. , Murthy Vadivelam , Bhat Prashanth , Fox Grenville F. , Campbell Morag E. , Milner Anthony D. , Greenough Anne 
Published: May 2019

Abstract

Background
Airway obstruction can occur during facemask (FM) resuscitation of preterm infants at birth. Intubation bypasses any upper airway obstruction. Thus, it would be expected that the occurrence of low expiratory tidal volumes (VTes) would be less in infants resuscitated via an endotracheal tube (ETT) rather than via an FM. Our aim was to test this hypothesis.

Methods
Analysis was undertaken of respiratory function monitoring traces made during initial resuscitation in the delivery suite to determine the peak inflating pressure (PIP), positive end expiratory pressure (PEEP), the VTe and maximum exhaled carbon dioxide (ETCO2) levels and the number of inflations with a low VTe (less than 2.2 mL/kg).

Results
Eighteen infants were resuscitated via an ETT and 11 via an FM, all born at less than 29 weeks of gestation. Similar inflation pressures were used in both groups (17.2 vs. 18.8 cmH2O, P = 0.67). The proportion of infants with a low median VTe (P = 0.6) and the proportion of inflations with a low VTe were similar in the groups (P = 0.10), as was the lung compliance (P = 0.67). Infants with the lowest VTe had the stiffest lungs (P < 0.001).

Conclusion
Respiratory function monitoring during initial resuscitation can objectively identify infants who may require escalation of inflation pressures.
Characterizations of Convex spaces and Anti-matroids via Derived Operators
Authors: Chen Fanhong , Shen Chong 
Published: May 2019

Abstract
In this paper we use the notion of derived sets to study convex spaces. By axiomatizing the derived sets on convex spaces, we define c-derived operators and restricted c-derived operators. Results show that convex structures can be characterized in terms of c-derived operators. Furthermore, the link between c-derived operators and Shi’s m-derived operators is studied. Specifically, it is proved that a c-derived operator is an m-derived operator if and only if it satisfies the Exchange Law. At last, we show an application of c-derived operators to anti-matroids.
Effects of Rehabilitation in Bankart Lesion in Non-athletes: A report of three cases
Authors: Hwan Kim Yong , So Wi-Young 
Published: May 2019

Abstract
A Bankart lesion is a common traumatic sports injury of the glenohumeral joint. When the shoulder is dislocated, the connective tissue surrounding the joint may tear or rupture. This study aimed to describe the initial dislocation, treatment, medical treatment, rehabilitation outcomes at 3 and 8 months, and return to daily life for three patients. Patient 1 was a 28-year-old male office worker who enjoyed fitness and weight training. His injury was sustained by a fall from his bicycle and subsequent performance of pull-up exercises. Surgery was recommended for repair of the anterior and inferior labrum tear. Reassessment of the surgery was performed after 2 months of rehabilitation. The patient was asked to exercise once a week at a rehabilitation center and to perform home-based exercises. In the first 2 months, the main exercise consisted of range of motion (ROM) exercises and stretching. Thereafter, muscle strengthening, using tubing, equipment and body weight exercises, and proprioceptive exercises were performed to gradually improve muscle strength and for return to daily activities. ROM progressively increased, with recovery of normal range at 2 months post-surgery. However, pain decreased only slightly, with a visual analog score of 6 out of 10 at 2 months post-surgery. At 8 months, the pain was bearable, without causing discomfort. Muscle strength remained almost unchanged initially but gradually recovered, although with a residual deficit of 20–30% in flexion, adduction and internal rotation. Considering the prolonged rehabilitation after surgery, future studies are warranted to analyze the long-term effects of non-surgical therapies by accumulating more cases and developing effective exercise rehabilitation programs.
Matrix metalloproteinase 2 knockdown suppresses the proliferation of HepG2 and Huh7 cells and enhances the cisplatin effect
Authors: Liu Jiangwei , Li Xiaocheng , Huang Jianzhao , Liu Yan 
Published: May 2019

Abstract

Background
This study evaluated the functions of matrix metalloproteinase 2 (MMP2) in hepatocellular carcinoma (HCC) cells and assessed the effects of MMP2 on HCC cell sensitivity to cisplatin.

Methodology
HepG2 and Huh7 cells were cultured. A pre-experiment was performed to explore the optimal transduction conditions of the MMP2-siRNA lentivirus (si-MMP2). Quantitative real-time PCR and western blot assays were performed to measure the expression levels of MMP2 in HepG2 and Huh7 cells. An MTT assay was used to evaluate cell proliferation, and flow cytometry analysis was applied to examine cell apoptosis. A Transwell assay was carried out to assess cell invasion.

Results
The optimal virus:cell ratio was 100 multiplicity of infection (MOI) for both cells, and the optimal transduction times for HepG2 and Huh7 cells were 48 h and 72 h, respectively. MMP2 knockdown significantly decreased the mRNA and protein levels of MMP2 in both cell lines (P<0.01). MMP2 knockdown significantly decreased the proliferation and increased the apoptosis of HepG2 and Huh7 cells (P<0.01). Co-treatment with si-MMP2 and cisplatin significantly increased the sensitivity of HepG2 and Huh7 cells to cisplatin (P<0.01).

Conclusion
MMP2 may act as an oncogene and may be a potential therapeutic target in HCC.
