Brain activation induced by different strengths of hand grasp: a functional magnetic resonance imaging study

Mirror neuron system can be activated by observation and execution of an action. It has an important function of action understanding. We investigated brain activations in humans by observing the strength of a hand grasp using functional magnetic resonance imaging. Twenty right-handed healthy individuals, consisting of 10 males and 10 females, aged 22.40 ± 2.04 years, were recruited into this study from September to November 2017 via posters. Light hand grasp task video showed a hand lightly grasping and releasing a ball repeatedly. Powerful hand grasp task video showed a hand tightly grasping and releasing a ball repeatedly. Functional magnetic resonance imaging block design paradigm comprised five stimulation blocks alternating with five baseline blocks. Stimulation blocks were presented with two stimulus tasks, consisting of a light grasp and a powerful grasp. Region of interest was defined around the inferior parietal lobule, inferior frontal gyrus, and superior temporal sulcus which have been called mirror neuron system. The inferior parietal lobule, fusiform, postcentral, occipital, temporal, and frontal gyri were activated during light and powerful grasp tasks. The BOLD signal response of a powerful grasp was stronger than that of a light grasp. These results suggest that brain activation of the inferior parietal lobule, which is the core brain region of the mirror neuron system, was stronger in the powerful grasp task than in the light grasp task. We believe that our results might be helpful for instructing rehabilitation of brain injury. This study was approved by the Institutional Review Board of Daegu Oriental Hospital of Daegu Haany University on September 8, 2017 (approval No. DHUMC-D-17020-PRO-01).
Observations of turbulence at a near-surface temperature front in the Arctic Ocean

<p>Measurements made at an Arctic thermohaline front show turbulence production through convection and forced symmetric instability, a mechanism drawing energy from the frontal geostrophic current. Destabilizing surface buoyancy fluxes from a combination of heat loss to the atmosphere and cross-front Ekman transport by down-front winds reduce the potential vorticity in the upper ocean. The front, located in the Nansen Basin close to the sea ice edge, separates the cold and fresh surface melt water from the warm and saline mixed layer. High resolution temperature, salinity, current and turbulence data were collected in the upper 100 m, on 18 September 2018 across the front from a research vessel and an autonomous underwater vehicle. The AUV was deployed to autonomously collect high resolution data across the front using adaptive sampling. Both front detection and sampling location were decided by a state-based autonomous agent running onboard the AUV, optimizing data collection across and along the front. </p><p>In addition to convection by heat loss to atmosphere and mechanical forcing by moderate wind in the mixed layer, forced symmetric instability contributed with comparable magnitude in generation of turbulence at the front location down to 40 m depth. This turbulence was associated with turbulent heat fluxes of up to 10 W.m<sup>-2</sup>, eroding the warm and cold intrusions observed at respectively 35 and 55 m depth. A similar frontal structure has been crossed by a Seaglider in the same region 10 days after our survey. The submesoscale-to-turbulence scale transitions and resulting mixing can be widespread and important in the Atlantic sector of the Arctic Ocean. </p>

Refractory Sjogrens syndrome: Is parotidectomy justified?

Primary and secondary Sjogrens syndrome (SS) is the classification used, according to the American-European Consensus Group Criteria. Salivary and lacrimal gland dysfunctions are the usual hallmark of the disease, but the involvement of other exocrine glands and extraglandular manifestations of the disease do occur. In rare cases, few patients are refractory to the conventional therapy and due to the sudden increase in size of a mass and the esthetic and psychological concerns of a “cancerous growth,” the surgical treatment modalities have to be modified. There is a significant lack of contemporary literature on the indications for surgery in refractory SS, and the option should be given in patients with esthetic concerns, risk of malignancy, and to improve the overall quality of life.
C1:C2 ratio is a potential tool assessing atlas fracture displacement and transverse ligament injury

Objectives: The aim of this study was to determine the reliability of a C1:C2 ratio in a cohort of patients with atlas fractures. Second, we aimed to consider the utility of the C1:C2 ratio with regard to diagnosis of transverse ligament (TL) injury. Design: This is a retrospective analysis. Methods: Patients with atlas fractures in the Waikato region between 2008 and 2010 were identified retrospectively through clinical coding and collated radiology trauma database. Main Outcome Measurements: The maximal width of C1 and C2 was measured using the first-taken trauma radiograph series. Combined overhang of lateral masses (△mm) and a C1:C2 ratio was then calculated. Final ratio and atlanto-dens interval (ADI) were measured at the last clinical follow-up. Results: A total of 24 patients with full radiographic records were included. Of these, five patients (21%) had TL injuries confirmed on computed tomography or magnetic resonance imaging. No patient with a ratio 1.15 had an intact TL, whereas a ratio of >1.10 captured 80% of TL injuries. The ratio ( P < 0.001) and delta values ( P < 0.001) were statistically significantly different between TL-injured and TL-intact cohorts. Two patients in the TL injury group demonstrated increased ADI on final follow-up with a ratio of >1.10. Conclusions: A C1:C2 ratio >1.10 on plain radiographs showed a sensitivity of 80% in detecting atlas fractures with associated TL injury. All patients with a ratio of ≥1.15 had TL rupture subsequently confirmed by an advanced modality. A ratio calculation on radiographs is a potentially useful method of describing atlas lateral mass displacement. Level of evidence: Level III
Comparative Evaluation of Treatment of Localized Gingival Recessions with Coronally Advanced Flap Using Microsurgical and Conventional Techniques

Background: Coverage of gingival recession is a very precision-oriented procedure. Employment of operating microscope has proved to be a boon in various surgical procedures and therefore can have positive benefits on the outcome of a procedure. Aim: The aim of this study is to find out whether the use of an operating microscope in the surgical treatment of Millers Class I and Class II gingival recession defects could improve the outcome in terms of root coverage and final tissue appearance compared to those done by the conventional technique. Materials and Methods: This clinical study was carried out on ten patients with the presence of bilateral isolated gingival recession classified as Miller's Class I or Class II recession defect. The split-mouth design was used where coronally advanced flap with the placement of platelet-rich fibrin was done in defects in test (microsurgical) and control (conventional) groups. Various clinical parameters were recorded at baseline and then postoperatively at 3-months and 6-month intervals. Results: The visual analog scale scores showed a statistically significant difference between scores while all other parameters had no statistically significant difference in intergroup comparison after 3 and 6 months. Conclusion: While microscope permitted less traumatic and minimally invasive procedure, both groups showed convincing improvement in clinical parameters.
Magnetized bioconvection flow of Sutterby fluid characterized by the suspension of nanoparticles across a wedge with activation energy

Nanofluids are playing a vital part in advancing practical life. The potential application of nanomaterials in a multitude of scenarios, such oil recovery, the melting of electronic systems in computers, cooling systems, the construction of fluid, cooling spirals, engineering and manufacturing, heat storage devices, and bioengineering. The microorganisms have a vital role to play in numerous applications, such as biological sciences, drugs, and biotechnology, biofuels processing, wastewater treatment, and food production. The current investigation exhibits a numerical model for Sutterby fluid with activation energy, thermal radiation, and bioconvection flowing past a stretching/shrinking wedge. The set of conservative governing partial differential equations (PDEs) is converted into a dimensionless ODEs system by using suitable similarity variables. The obtained new system of the model with dimensionless relative boundary conditions is tackled numerically by manipulating the famous shooting method through bvp4c solver in MATLAB coding. The physical and mathematical findings for profiles of velocity, temperature, concentration, and microbe dispersion owing to various controlling parameter inputs are displayed in tables and graphs. Flow velocity is shown to decrease as the bioconvection Rayleigh number increases. Moreover, the Prandtl number increases, the thermal field of the fluid decreases while it increases for the temperature ratio parameter. Furthermore, it is determined from this situation that the concentration field decreases as the Brownian motion parameter increases. The field of the microorganism decreases as the Peclet number increases.
Tar-filled shells and tar balls on the Alabama Gulf coast host distinctive bacterial communities

Abstract. Tar balls have been persisting along the Gulf coast. Previous research has shown that tar balls from the Gulf coast may contain the human pathogen Vibrio vulnificus. These oil residuals are also commonly found beneath sea shells (hereby called “tar shells”). No research, however, has explored the bacterial communities in tar shells. In this study, tar shell, tar ball, and sand samples on the Alabama Gulf coast at intertidal and supratidal zones were collected and their bacterial communities were assessed using PCR-DGGE and DNA sequencing. Our data suggest that Desulfovibrio and Actinobacteria spp. are dominant in tar shells at intertidal and supratidal zones, but not in tar balls at supratidal zone, while Pseudoalteromonas spp. are dominant in both tar balls and tar shells. This research provides preliminary data for future studies to assess the impacts of tar balls and tar shells on coastal environments and human health.
Neuronal and peripheral damages induced by synthetic psychoactive substances: an update of recent findings from human and animal studies

Preclinical and clinical studies indicate that synthetic psychoactive substances, in addition to having abuse potential, may elicit toxic effects of varying severity at the peripheral and central levels. Nowadays, toxicity induced by synthetic psychoactive substances poses a serious harm for health, since recreational use of these substances is on the rise among young and adult people. The present review summarizes recent findings on the peripheral and central toxicity elicited by “old” and “new” synthetic psychoactive substances in humans and experimental animals, focusing on amphetamine derivatives, hallucinogen and dissociative drugs and synthetic cannabinoids.

A study of ruthenium-based catalysts used in homogeneous transfer hydrogenation of acetophenone

It was determined that RuCl2(PPh3)3 obtained with a modified method described by Shaw’s group (Shaw et al., 2007) had the best catalytic properties in the reaction performed under conditions described in Liang Wang’s publication (Wang et al., 2014). It was also determined that for concentration ratio of substrate to RuCl2(PPh3)3 amounting to 250:1 the conversion rate was much higher than that of the reaction performed with a double dose of the catalyst. Results of experiments also show that samples of the post-reaction solution should be analyzed right after the reaction, because even if they are stored in low temperature the amount of product can change up to 3–5% compared to the base sample and this change is not predictable.
Visual Attention Demand Evaluation of Conventional and Multifunction in-Vehicle Information Systems

This paper describes part of a larger on-road test of a candidate control layout and system organization for a reconfigurable, automotive multifunction information system. Driver visual scanning behavior and task performance were examined. Six younger and six older drivers each performed 15 in-vehicle tasks while driving. Drivers executed functions for both current vehicle systems (e.g., audio, climate, and cell phone) and advanced/future vehicle systems (e.g., navigation, email, and communications/video). Six similar tasks were performed using both the experimental vehicle's conventional information systems and the candidate design multifunction information system. Results showed that task completion times were longer for tasks performed using the multifunction information system, compared to the conventional vehicle systems. Longer tasks completion times were associated with higher frequency of driver eye glances to the in-vehicle system. In addition, task completion times were found to be related to certain measures of driving task performance, most notably lateral control and speed control.

A Shader Language Off-line Cross-Compiler on the Desktops

In our modern computer graphics systems, they use GPUs (graphics processing units) to execute the low-level parallel instructions, compiled from the shader language source codes. Recently, some graphics system specifications, including OpenGL SC 2.0, introduce the off-line compilation. With this new scheme, the independent off-line compiler will generate the final binary executable codes. Typically, the target system will execute the pre-compiled binary executable codes, at some time later. In this paper, we analyzed the detailed requirements on the shader language off-line compilation. Based on these analysis, we designed the whole compiling process and the binary file format for the off-line compiler. As the verification process of our design, we implemented the prototype off-line compiler for our existing OpenGL SC 2.0 implementation on the target embedded system. We executed a set of pre-compiled binary files on the target system, and all the results are the same to the desktop executions. We finally showed that the shader language off-line compilers are possible with our proposed schemes.

Effects of Dimethoate on Condition Factor and Organosomatic Indices of Heterobranchus Longifilis (Valenciennes, 1840)

In recent times, pollution has been a most important threat to the sustainability of aquatic environment [1]. The use of chemicals in various agriculture operations have been on the increase especially on the developing countries across the globe [2]. Pesticides can be described as substances that are used for controlling pest in homes and agricultural field. In the recent times, pesticides use is on the increasing trend. As such, pesticides are among the important pollutants of the aquatic ecosystem [3]. Conversely, Gabriel et al. [4] reported that chemicals such as pesticides are among the most potentially harmful chemicals introduced into the aquatic environment through various human activities. Several collections of these pesticides are lethal to the non-targeted organisms especially fish in the aquatic environment [5]. The degree of toxicity of these chemicals depends largely on their compositions, rate and mode of application and as well as the immune system and other metabolic pathways of the target organisms. Apart from these, agrochemicals can also be classified based on target organisms. Classification based on targets organisms includes insecticides, rodenticides, herbicides and fumigants [6, 7].
