Recent advances in atmospheric plasmas have led to the formation of nonthermal plasma (NTP). In recent decades, a number of novel plasma diagnostic approaches have been implemented and reported in ...order to better understand the physics of NTP. The use of NTP is a novel approach to producing reactive oxygen and nitrogen species. Plasma technology has many applications, including electrical device microfabrication, biomedicine, dentistry, agriculture, ozone generation, chemical synthesis, surface treatment, coating, and disease therapy. Furthermore, NTP is thought to be a successful strategy for the degradation of hazardous pollutants in the environment, making it a future hope. Recent studies showed that various operating parameters affect the yield of NTP-based technology. Especially, the presence of a catalyst, properly placed in an NTP reactor, leads to a significant increase in process performance as compared to NTP alone. Scientists have looked at using NTP in conjunction with catalysts to remove various sorts of pollutants from the environment. In this context, review articles are crucial due to the prevalence of NTP-based applications and ongoing developments. This review will describe recent advancements in NTP-based biomedical applications, bacterial inactivation, food preservation and storage, and environmental catalytic formulations. This review could be useful in providing a platform for advancements in biological applications and environmental protection through the use of NTP technology.
Increasing the seed germination potential and seedling growth rates play a pivotal role in increasing overall crop productivity. Seed germination and early vegetative (seedling) growth are critical ...developmental stages in plants. High-power microwave (HPM) technology has facilitated both the emergence of novel applications and improvements to existing in agriculture. The implications of pulsed HPM on agriculture remain unexplored. In this study, we have investigated the effects of pulsed HPM exposure on barley germination and seedling growth, elucidating the plausible underlying mechanisms. Barley seeds underwent direct HPM irradiation, with 60 pulses by 2.04 mJ/pulse, across three distinct irradiation settings: dry, submerged in deionized (DI) water, and submerged in DI water one day before exposure. Seed germination significantly increased in all HPM-treated groups, where the HPM-dry group exhibited a notable increase, with a 2.48-fold rise at day 2 and a 1.9-fold increment at day 3. Similarly, all HPM-treated groups displayed significant enhancements in water uptake, and seedling growth (weight and length), as well as elevated levels of chlorophyll, carotenoids, and total soluble protein content. The obtained results indicate that when comparing three irradiation setting, HPM-dry showed the most promising effects. Condition HPM seed treatment increases the level of reactive species within the barley seedlings, thereby modulating plant biochemistry, physiology, and different cellular signaling cascades via induced enzymatic activities. Notably, the markers associated with plant growth are upregulated and growth inhibitory markers are downregulated post-HPM exposure. Under optimal HPM-dry treatment, auxin (IAA) levels increased threefold, while ABA levels decreased by up to 65 %. These molecular findings illuminate the intricate regulatory mechanisms governing phenotypic changes in barley seedlings subjected to HPM treatment. The results of this study might play a key role to understand molecular mechanisms after pulsed-HPM irradiation of seeds, contributing significantly to address the global need of sustainable crop yield.

Right ventricular (RV) function is a major determinant of clinical outcome, but its function indices have not been studied well in surgery for rheumatic valvular heart disease. The aim of this study ...was to determine the correlation of tricuspid annular plane systolic excursion (TAPSE) with outcome of rheumatic heart valve surgery.
A prospective comparative study was conducted including 100 eligible patients who were divided into two groups based on RV function as assessed by TAPSE measured by two-dimensional (2D) echocardiography preoperatively. Those with TAPSE less than 15 mm were included in group 1 and those with TAPSE of 15 or more were included in group 2.
50 patients were included in group 1 and 50 patients in group 2. Mean age of the patients was 56.78 ± 15.21 years in group 1 and 54.46 ± 15.03 years in group 2 (P = 0.444). 34 (34%) patients underwent aortic valve replacement (AVR), 35 (35%) underwent both aortic and mitral valves replacement, and 31 (31%) ones had mitral valve replacement (MVR). A significant difference was found between the duration of ventilation (5.15 ± 2.80 hours in group 1 vs. 3.72 ± 2.71 hours in group 2, P = 0.001), postoperative inotropic requirement more than 24 hours in 18 (36%) patients in group 1 vs. 7 (14%) patients in group 2, P = 0.003, total intensive care unit (ICU) stay (8.92 ± 3.62 days in group 1 vs. 5.20 ± 2.06 days in group 2, P = 0.001), and mortality 7 (14%) in group 1 vs. 2 (4%) in group 2, P = 0.038.
TAPSE less than 15 mm in patients undergoing surgical correction for rheumatic valvular heart disease leads to poor outcomes. These patients need special attention perioperatively.
The Global outbreak of COVID-19 pandemic affected almost all countries and territories worldwide. The outbreak was first identified from Wuhan, China, in December 2019 and was declared a pandemic in ...March 2020. Virus incubation time is usually 7 days and initial symptoms includes fever, cough, flu, muscle fatigue and difficulty in breathing. Ibuprofen and paracetamol are the two most commonly used over the counter (OTC) drugs to treat fever due to COVID-19. Some researchers discouraged the use of ibuprofen initially due to possible adverse effects related with longevity of infection, increased morbidity, and mortality rate. This study aimed to compare the effectiveness of paracetamol and ibuprofen as anti-pyretic drugs to treat fever caused in COVID-19 infection. A systematic review of major databases i.e., PubMed, Cochrane library, Web of Science, Google scholar and ClinicalTrials.gov was performed, to screen the studies conducted on managing fever using paracetamol and ibuprofen. Review of the selected articles based on the inclusion/exclusion criteria was performed by two independent researchers. The titles of selected publications were screened for relevance to the preset criteria followed by review of the abstracts. Finally, the full-length articles were evaluated for the final selection of studies to be included. Outcomes of use of ibuprofen and paracetamol were estimated by analyzing selected case control and cohort studies. Overall, eleven observational studies were selected for the compilation of systematic review, based upon the preset inclusion/ exclusion criteria. All studies included adult COVID-19 patients both male and female from different age groups. Paracetamol users were compared with ibuprofen users and no adverse effects of ibuprofen were found related to longevity of infection, complications, increased mortality rate and ventilation support requirement, when treating fever or pain caused by COVID-19.However, further studies and randomized control trials need to be conducted to assess and compare the effectiveness of these drugs to manage fever caused by coronavirus disease.
The aim of this study to examine how critical success factors (CSFs) affect the project success (PS), directly and indirectly, using the despotic leadership (DL) as a mediating variable. Critical ...success factors with multiple dimensions, such as organizational factors, team factors, technical factors, and communication factors, were used in this study. In this study, we used a questionnaire survey approach. The data were collected from the project directors, project managers, functional managers, and team leaders working in the renewable energy project of Pakistan. For data analysis, we used the partial least squares structural equation modeling through SmartPLS 3.2. The outcomes indicate that team factors and communication factors have a positive and significant relationship with PS in the direct relationship. At the same time, organization factors and technical factors were insignificant in the direct relationship with PS. Moreover, to examine the mediating effects of despotic leadership, we have examined the indirect effects of critical success factors on PS. The findings of this study indicate that DL is not mediated between organizational factors and PS in the indirect relationship. However, DL negatively mediates between three factors (team, technical, and communication) of critical success factors on project success. This paper concludes that despotic leaders go beyond controlling and self-serving behaviour and are engaged in exploitative and unethical acts that can drain project resources, which reduce the success and sustainability of renewable energy projects.
The purpose of this study is to understand how leader humility effectively stimulates follower creativity in the workplace during the coronavirus disease 2019 (COVID-19) scenario. Relying on social ...cognitive and social information processing theories, this study investigates how leader humility cultivates follower self-efficacy and follower creativity. Furthermore, it explores an intervening mechanism of follower self-efficacy and examines a moderating role of leader proactive personality. The hypothesized model is empirically tested by collecting the data from 405 employees and 87 managers working in the banking sector of Pakistan. The results indicate that leader humility is positively related to follower self-efficacy and follower creativity, which improve the organization's innovation climate and an environment for social sustainability. Follower self-efficacy is also significantly related to follower creativity. The mediation analysis shows that follower self-efficacy mediates the relationship between leader humility and follower creativity. Additionally, leader proactive personality moderates the relation between follower self-efficacy and follower creativity. This study highlights the importance of leader humility for creativity and extends the literature by explaining the role of self-efficacy. Furthermore, the findings may assist the policymakers in how a humble leader heightens employee creativity and social sustainability in COVID-19.
