Research amongst Physical Therapists in the State of Kuwait: Participation, Perception, Attitude and Barriers

&lt;b&gt;&lt;i&gt;Objectives:&lt;/i&gt;&lt;/b&gt; The objectives of this descriptive study were to investigate the attitudes and perceptions of physical therapists regarding research, the intention to engage in research and the barriers to participating in research amongst physical therapists in the State of Kuwait. &lt;b&gt;&lt;i&gt;Subjects and Methods:&lt;/i&gt;&lt;/b&gt; A previously validated questionnaire was distributed to 200 non-randomly selected physical therapists. The questionnaire gathered demographic data as well as information regarding research-related activities. Descriptive statistics, frequency and &amp;#x03C7;&lt;sup&gt;2&lt;/sup&gt; analyses were used in this study. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; Of the 200 questionnaires distributed to physical therapists 122 (61%) were completed and returned. The physical therapists had a positive attitude towards reading these findings in order to update their knowledge. However, only 16 (17%) of the physical therapists participated in clinical research. The common reasons given were: minimal role and reduced ability, intention and level of engagement in initiating research, probably due to work overload, time constraints and limited access to resources. &lt;b&gt;&lt;i&gt;Conclusions:&lt;/i&gt;&lt;/b&gt; Physical therapists in Kuwait had a positive attitude towards the application of research findings to their practice. However, they were not confident in initiating research due to work overload and lack of time as well as limited access to library resources. Therefore, we recommend stimulation to engage in research activities to be a requirement and to develop a system to improve the skills and knowledge of doing research.</jats:p

Rosiridin Attenuates Scopolamine-Induced Cognitive Impairments in Rats via Inhibition of Oxidative and Nitrative Stress Leaded Caspase-3/9 and TNF-α Signaling Pathways

Aim: A monoterpene and bioactive component of the plant Rhodiola rosea (R. rosea), rosiridin has beneficial effects on the human central nervous system and enhances brain function. The goal of this scientific study was to determine if rosiridin might shield rats from neurocognitive problems induced by scopolamine. Methods: To track the potential toxicities in rats, the acute toxicity in rats was clarified. Rosiridin at a dose of 10 mg/kg was tested in rats for 14 days. At the conclusion of the investigation, behavioral parameters that were used to identify the rats’ cognitive and motor abilities were evaluated. Several biochemical parameters were estimated using the prepared homogenate, including acetylcholine esterase (AChE), choline acetyltransferase (ChAT), radical scavengers produced by the body (Catalase-CAT, superoxide dismutase-SOD, and reduced glutathione-GSH), indicators of oxidative and nitrative burnout, pro-inflammatory (Interleukins- IL-1β, IL-6, interferon gamma IFN-ꝩ, and tumor necrosis factor-TNF-α), and cell apoptosis caspases 3 and 9. Results and Conclusion: A significant behavioral parameter restoration was seen in the rosiridin-treated group, including reduction in latency time during acquisition and retention trial in the Morris water maze test, and percentage of spontaneous alterations in the y-maze test, when compared to the disease control group that received scopolamine; rosiridin also altered the oxidative stress and neuroinflammatory markers, as well as restoring Ach and ChAT activities and normalizing GSH, SOD, MDA, TNF-α, nitrate, IL-1β, IL-6, IFN-ꝩ, caspases 3 and 9 levels. The results imply that rosiridin limits the effect of scopolamine on rat cognitive function

Modification of CeNi0.9Zr0.1O3 Perovskite Catalyst by Partially Substituting Yttrium with Zirconia in Dry Reforming of Methane

Methane Dry Reforming is one of the means of producing syngas. CeNi0.9Zr0.1O3 catalyst and its modification with yttrium were investigated for CO2 reforming of methane. The experiment was performed at 800 °C to examine the effect of yttrium loading on catalyst activity, stability, and H2/CO ratio. The catalyst activity increased with an increase in yttrium loading with CeNi0.9Zr0.01Y0.09O3 catalyst demonstrating the best activity with CH4 conversion &gt;85% and CO2 conversion &gt;90% while the stability increased with increases in zirconium loading. The specific surface area of samples ranged from 1–9 m2/g with a pore size of 12–29 nm. The samples all showed type IV isotherms. The XRD peaks confirmed the formation of a monoclinic phase of zirconium and the well-crystallized structure of the perovskite catalyst. The Temperature Program Reduction analysis (TPR) showed a peak at low-temperature region for the yttrium doped catalyst while the un-modified perovskite catalyst (CeNi0.9Zr0.1O3) showed a slight shift to a moderate temperature region in the TPR profile. The Thermogravimetric analysis (TGA) curve showed a weight loss step in the range of 500–700 °C, with CeNi0.9Zr0.1O3 having the least carbon with a weight loss of 20%.</jats:p
