Strip-type Sensor for Blood Glucose Measurement through Tear Fluid

A strip-type sensor with sensing paper treated with cerium oxide nanoparticles (CNPs) and glucose oxidase (GOX) was designed to detect glucose levels in tears. The strip-type sensor was produced by 3D printing. It is put against the inferior palpebral conjunctiva (IPC) to collect tears without irritating the eyes. When GOX reacts with the glucose in the collected tears, hydrogen peroxide (H 2 O 2 ) is generated, and this H 2 O 2 reacts with the CNP. The H 2 O 2 causes the Ce 3+ on the surface of the CNP to turn into Ce 4+ , and the color of the CNP becomes yellow. Therefore, the higher the concentration of glucose, the higher the amount of H 2 O 2 produced and the more yellow the CNP becomes. The concentration of glucose in the tears can be measured with an optical vision system that measures the degree of yellowing of the CNP on the sensing paper. After the sensing paper turns yellow, a RGB detection was performed through a colorimetric analysis algorithm. In the in vitro experiments, the sensing paper was loaded into the strip-type sensor. The normalized b value and glucose concentration showed a linear correlation. A tear glucose index was created from these results. The strip-type sensor was also tested in an in vivo rabbit model and the correlation between blood glucose and tear glucose was confirmed, thus suggesting that strip-type sensors are useful as a self-diagnostic sensor.
Water Stress Index Detection Using a Low-Cost Infrared Sensor and Excess Green Image Processing

Precision Irrigation (PI) is a promising technique for monitoring and controlling water use that allows for meeting crop water requirements based on site-specific data. However, implementing the PI needs precise data on water evapotranspiration. The detection and monitoring of crop water stress can be achieved by several methods, one of the most interesting being the use of infra-red (IR) thermometry combined with the estimate of the Crop Water Stress Index (CWSI). However, conventional IR equipment is expensive, so the objective of this paper is to present the development of a new low-cost water stress detection system using TL indices obtained by crossing the responses of infrared sensors with image processing. The results demonstrated that it is possible to use low-cost IR sensors with a directional Field of Vision (FoV) to measure plant temperature, generate thermal maps, and identify water stress conditions. The Leaf Temperature Maps, generated by the IR sensor readings of the plant segmentation in the RGB image, were validated by thermal images. Furthermore, the estimated CWSI is consistent with the literature results.

Abstract. The purpose of the research is to determine and explain the effects of a combined workout training consisting in tennis specific sprints combined with a plyometric training. Our objectives were to analyze the effects of this type of combined training on the variable performance movements in tennis. This training has been performed for 10 weeks, three times/week with a total of 30 sessions. Forty-eight male adolescent tennis players, aged between 14 and 16 years old, participated in this study. They were divided into two groups, a control group of 23 subjects and an experimental group of 25 subjects. The participants had to have a minimum experience of 2 years of participating in competitions at a national level. The physical tests that have been used to measure their performances were: added steps, the Spider test, Illinois agility test and T-test. The statistical program used for analyzing the data was the program named SPSS version 24. To verify the obtained results, several statistical tests have been used, such as T-Test for independent samples, Pearson correlation and paired t-test. Following statistical analysis of data, it was concluded that the two groups differ significantly in terms of tennis movements performance, after the application of the training program (the results of the experiment group are better than those of the control group at the end of the intervention).

The recommendation for Shopee is to focus more on minimizing the risk of its consumers, including the risk of being infected with Covid-19.
In vitro and in vivo studies of the antidiabetic potential of Red Sea sponge-associated fungus “Aspergillus unguis” isolate SP51-EGY with correlations to its chemical composition

Diabetes mellitus is one of the most prevalent chronic diseases. The main objective is to determine ‎antidiabetic and antioxidant activities of Red Sea sponge-associated fungus “ Aspergillus ‎unguis ” isolate SP51-EGY secondary metabolites with concomitant gas chromatography/mass spectrometry (GC/MS) analysis of active extracts. ‎ In vitro α-glucosidase inhibition and antioxidant capacity were determined. In vivo , LD 50 was determined in mice. Streptozotocin-induced diabetic mice were treated with mycelial-free culture filtrate and mycelial extracts. Serum blood glucose, serum C-peptide, glucagon-like peptide-1 (GLP-1), α-glucosidase, and adiponectin levels were estimated. Shake (Sh) filtrate and mycelial extracts demonstrated the highest significant in vitro α-glucosidase inhibitory activity. Sh mycelia demonstrated higher antioxidant capacity compared to Sh filtrate. In vivo , treatment with Sh mycelia (50 and 100 mg/kg) significantly lowered the blood glucose level by 27% and 54%, respectively, while Sh filtrate (125 and 250 mg/kg) significantly decreased the blood glucose level by 49% and 70%, respectively, compared to the diabetic group, respectively. Filtrate and mycelial extracts significantly increased C-peptide, GLP-1, and adiponectin, while significantly inhibiting α-glucosidase serum level compared to the diabetic group. GC/MS analysis revealed a high percentage of isovanillic acid; d-friedoolean-14-en-3-one; isochromanone derivative in filtrate extract; and palmitic, linolenic acids, and their esters in the mycelial extract. Therefore, secondary metabolites could be considered an effective strategy in the regulation of blood glucose level.
A bounded version of the Nash-Sutcliffe criterion for better model assessment on large sets of basins

Rainfall-runoff models are useful tools for hydrological research, water engineering and environmental applications. Given the large number of available rainfall-runoff models, many comparative studies have been done to compare models performances, to specify their domain of application and provide guidance to end-users. Although most existing comparative studies tested models only on a few basins, we believe that effective model evaluation requires large samples of test catchments. However, large test samples raise the issue of appropriate criteria to quantify model performances. This paper shows that the widely used Nash and Sutcliffe criterion may be difficult to apply for large test samples and that a bounded version of this criterion (called C 2M ) is better suited for extensive model assessment.
Comparative study of direct seeding and transplanting of rice

In a field experiment conducted during rainy (Kharif) seasons on direct seeding (DSR) at optimum moisture condition and transplanting (TPR) in puddled fields by taking short and medium duration varieties of rice, grain yield under these two methods were at par during initial two years but were 15.2% and 9.1% less in DSR in subsequent yezors. The reduction in yield in DSR was attributed to the heavy infestation of weeds in subsequent years and also delay in first manual weeding beyond 20 days after sowing. The percolation rate was about 15% less in lPR than DSR however, the total water use was almost the same in both methods. Average water use efficiency (NUE) was 10.7% more in TPR than DSR. DSR gave only 16% less net returns during initial two years and net return further decreased in subsequent years. There was no significant interaction between varieties and methods but medium duration varieties gave higher yield, WUE, and net returns over short duration variety.

Paired Cluster Model of High-Tc Superconductivity:Explanation for Pseudogap Critical Concentration, Vortex Core Pseudogap and Possible Stripe Phase in High-Tc Superconductors

A new model of high-T_c superconductivity (HTSC) has been developed by us which we find is able to explain almost all the HTSC properties, like high T_c, origin and nature of NSPG (normal state pseudogap), anomalous superconducting state (SS) energy gap (SSEG) properties, absence of NMR spin relaxation rate coherence peak, existence of NSPG below T_c, nature of high-T_c magnetic superconductivity, external magnetic field (H) dependence of the NSPG formation temperature T*, etc. The coexistence of NSPG and SS BCS energy gap (EG), below T_C, has been predicted by the model before its experimental observation, showing that the observed SSEG is a superposition of NSPG and SS BCS EG. In this paper we show that our model, called paired cluster (PC) model, is able to explain the pseudogap critical concentration, vortex core pseudogap and possible stripe phase in high-T_c superconductors.

Role of Autophagy Inducers and Inhibitors in Intestinal Barrier Injury Induced by Intestinal Ischemia–Reperfusion (I/R)

Objectives Intestinal epithelial barrier function is an important mechanical barrier to maintain intestinal homeostasis and resist the invasion of intestinal pathogens and microorganisms. However, intestinal epithelial barrier function is vulnerable to damage under intestinal ischemia–reperfusion (I/R) injury. Under a category of pathophysiological conditions, including I/R, autophagy plays a crucial role. This study is aimed at discussing the role of autophagy inhibitors and activators in intestinal epithelial barrier function after intestinal I/R by changing autophagy levels. Methods Mice with intestinal IR underwent 45 minutes of surgery for superior mesenteric artery occlusion. The autophagy inhibitor 3-MA and the autophagy inducer rapamycin (RAP) were used to change the level of autophagy, and then, the expressions of tight junction proteins and intestinal barrier function were detected. Results The results showed that the autophagy inhibitor 3-MA aggravated intestinal epithelial barrier dysfunction, while the autophagy inducer RAP attenuated intestinal epithelial barrier dysfunction. In addition, promoting autophagy may promote occludin expression by inhibiting claudin-2 expression. Conclusion Upregulation of autophagy levels by autophagy inducers can enhance intestinal epithelial barrier function after intestinal I/R.

Quasinormal modes of black holes and black branes

Quasinormal modes are eigenmodes of dissipative systems. Perturbations of classical gravitational backgrounds involving black holes or branes naturally lead to quasinormal modes. The analysis and classification of the quasinormal spectra require solving non-Hermitian eigenvalue problems for the associated linear differential equations. Within the recently developed gauge-gravity duality, these modes serve as an important tool for determining the near-equilibrium properties of strongly coupled quantum field theories, in particular their transport coefficients, such as viscosity, conductivity and diffusion constants. In astrophysics, the detection of quasinormal modes in gravitational wave experiments would allow precise measurements of the mass and spin of black holes as well as new tests of general relativity. This review is meant as an introduction to the subject, with a focus on the recent developments in the field.
The Adoption of Artificial Intelligence in Newsrooms in Kenya: a Multi-case Study

The deployment of Artificial Intelligence (AI) in newsrooms is gaining prominence worldwide, with the technology being used to enhance the processes of news gathering, packaging, and distribution. The study was guided by two research questions: what factors drive/hinder(s) the adoption of AI or lack of it in newsrooms in Kenya? Moreover, what opportunities do journalists feel are offered by adopting AI in newsrooms in Kenya? A qualitative research approach and descriptive research design were employed to investigate the adoption of AI in newsrooms in Kenya. British Broadcasting Corporation (BBC-Africa) and Radio Africa Group (RAG) media organizations were the target population. As a research strategy, a multi-case method was employed. The researchers conducted in-depth interviews with newsroom-based participants. A purposive sampling technique was used to select participants for the research. Collected data were analyzed thematically. The paper identified six factors driving the adoption of AI or lack of it: management buy-in, cost, technical skills, clarity of user case, perception, and company structure. Further, the study identified three challenges presented by adopting AI: lack of quality data, ethical concerns, and unpredictability of the technology’s impact. The study concludes that AI offers excellent opportunities for newsrooms in Kenya to explore. Still, some obstacles need to be addressed before they can benefit fully from the technology. The study projects that human and automated journalism will become closely integrated in the future and recommends that newsrooms in Kenya prepare to embrace AI by laying the foundation for its adoption. Media schools should update curricula to prepare journalists to work with emerging technologies such as AI. Further research is needed to identify the specific skill sets required for Kenyan digital journalists to embrace AI fully. Scholars should investigate how AI can shape new business models given shrinking revenues in the media.
Gradient estimates of harmonic functions and transition densities for Levy processes

We prove gradient estimates for harmonic functions with respect to a $d$-dimensional unimodal pure-jump Levy process under some mild assumptions on the density of its Levy measure. These assumptions allow for a construction of an unimodal Levy process in $\R^{d+2}$ with the same characteristic exponent as the original process. The relationship between the two processes provides a fruitful source of gradient estimates of transition densities. We also construct another process called a difference process which is very useful in the analysis of differential properties of harmonic functions.
A Case of a Thrombotic Storm (Arterial and Venous) in Nephrotic Syndrome

Nephrotic syndrome is a condition characterized by proteinuria, hypoalbuminemia, edema, hyperlipidemia, and a hypercoagulable state. Nephrotic syndrome may lead to several complications, including, but not limited to, increased risk of infection, respiratory distress, and thromboembolism. There are several etiologies of nephrotic syndrome with various predisposing factors ranging from idiopathic, autoimmune diseases, infections (human immunodeficiency virus, hepatitis C virus, hepatitis B virus), drugs, and heavy metal poisoning. Here, we report the case of a 37-year-old male who presented with worsening exertional dyspnea and bilateral lower extremity swelling. He was found to have simultaneous multiple acute thromboses in both the venous and arterial systems in the setting of worsening renal function. Further investigation revealed that the patient had membranous nephropathy. Initiation of anticoagulation and immunosuppression made a significant difference in his survival. Vascular thromboembolic (VTE) complications may be the initial presentation that prompts patients with nephrotic syndrome to seek medical care. As such, clinicians must have a high index of suspicion in patients presenting with concurrent VTE and nephrotic-range proteinuria. In addition, given that treatment modalities for the various etiologies of nephrotic syndrome differ considerably, it is also essential to distinguish the type of nephrotic syndrome in a patient, which dictates the treatment algorithm.
