This study is based on the modified Green-Lindsay Model (MGL) theory proposed by Yu et al. (2018). This model eliminates the discontinuous nature of the displacement field reported under the temperature-rate-dependent thermoelasticity theory (GL) established by Green and Lindsay. The present work obtains the analytical solution for the distributions of stress components, temperature and displacement through the potential function approach accompanied by the Laplace transform method. The inverse Laplace transformation is performed by using short-time approximation method to find the approximated analytical solution of the problem in space-time domain. A detailed analysis of solution is discussed for MGL model and compared to the results predicted by other existing generalized thermoelastic models. The effect of strain-rate and temperature-rate-terms is acknowledged explicitly in mathematical formulation and other significant effects are notified. However, this new model predicts the infinite speed of disturbance analogous to classical theory.","PeriodicalId":54759,"journal":{"name":"Journal of Thermal Stresses","volume":"46 1","pages":"1164 - 1179"},"PeriodicalIF":2.8,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43252234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pathophysiology of ocular hypertension has been linked to stress pathways, including fibrosis, calcification and the unfolded protein response (UPR). In a pharmacogenomic screen, we previously identified the novel G-protein-coupled receptor (GPCR), GPR158, showed that expression is upregulated in TM cells by glucocorticoid stress hormones, and showed that overexpression protects against oxidative stress. We also found that loss of Gpr158 in knockout mice negates IOP reduction due to treatment with the catecholamine stress hormone, epinephrine. An increase in GPR158 would be expected to alter the activity of GPR158-regulated pathways. Here, we profiled gene expression changes due to GPR158 overexpression by microarray, then conducted pathway analysis. We identified five upstream stress regulators relevant to ocular hypertension: dexamethasone and TGFB1 (fibrosis), XBP1 and ATF4 (UPR), and TP53 (cell cycle arrest). Key genes in the first three pathways were downregulated by GPR158 overexpression, but not enough to inhibit dexamethasone-induced fibrosis or calcification in TM cells, and loss of Gpr158 in knockout mice only minimally protected against dexamethasone-induced ocular hypertension. Depending on dose, GPR158 overexpression down- or upregulated the TP53 pathway, suggesting the mechanism for previously observed effects on cell proliferation. A sixth upstream regulator we identified was a GPCR: the beta-adrenergic receptor ADRB1. Adrenergic receptors serve as targets for IOP-lowering drugs, including epinephrine. These data provide new information about pathways regulated by GPR158.","PeriodicalId":54759,"journal":{"name":"Journal of Thermal Stresses","volume":"28 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80645041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study, based on in silico methods, was intended to increase the therapeutic potential of conventional drugs: hydroxychloroquine (HCQ), favipiravir (FAV), and remdesivir (REM) by using curcuminoids like curcumin (CUR), bisdemethoxycurcumin (BDMC), and demethoxycurcumin (DMC) as adjunct drugs against SARS-CoV-2 receptor proteins, namely main protease (Mpro) and the S1 receptor-binding domain (RBD). The curcuminoids exhibited similar pharmacokinetic properties to the conventional drugs. The webserver (ANCHOR) predicted greater protein stability for both receptors with a disordered score (<0.5). The molecular docking study showed that the binding energy was highest (−27.47 kcal/mol) for BDMC toward Mpro receptors, while the binding energy of CUR (−20.47 kcal/mol) and DMC (−20.58 kcal/mol) was lower than that of HCQ (−24.58 kcal/mol), FAV (−22.87 kcal/mol), and REM (−23.48 kcal/mol). In the case of S1-RBD, CUR had the highest binding energy (−38.84 kcal/mol) and the lowest was in FAV (−23.77 kcal/mol), whereas HCQ (−35.87 kcal/mol) and REM (−38.44 kcal/mol) had greater binding energy than BDMC (−28.07 kcal/mol) and DMC (−30.29 kcal/mol).

To better understand the growth of Leishmania and potential drug sensitivity implications, the effects of motion on cells grown in vitro were probed. Using a stock Leishmania tarentolae cell culture, cells were placed in 10 mL of a Brain–Heart Infusion medium in either a non-moving (static) environment or on a flat platform of one of two lab rockers (set at a minimal speed) in a dark environment for 13 days. Also, the addition of 0.5 M of L-Proline was evaluated. Microscopy, cell clumping, cell viability, and secreted acid phosphatase (SAP) activity data were collected. Results show that a constant slow rocking motion changed cell growth, clumping behavior, and detectable SAP activity relative to the no-motion cultures, but this change was dependent on which rocker was used, indicating a complexity in the growth of these cells in culture. Thus, continuous motion affects the stresses placed on the cells during a growth curve under some conditions. The implications of this study lead to questions about the effects of motion on the efficacy of pharmaceutical testing in vitro. Further study of the effects of motion on Leishmania is important.","PeriodicalId":54759,"journal":{"name":"Journal of Thermal Stresses","volume":"1 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89470377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess the combining abilities of preselected popcorn lines for agronomic and root traits under well-watered and water-stressed conditions. A circulating diallel analysis was conducted to investigate the effects of the general and specific combining abilities of 10 lines and their respective hybrids for various traits, including productivity, popping expansion, expanded popcorn volume, 100-grain weight, ear length, ear width, support root angle, crown root angle, number of support roots, number of crown roots, density of support roots, and density of crown roots. Non-additive action genes predominantly influenced the agronomic traits under both water conditions. In contrast, the root traits displayed a greater proportion of additive action gene expression under both conditions, despite being significantly affected by the environment. Lines L61, L71, and L76 demonstrated positive and high effects for general combining ability. The hybrids L65/L76, L71/L76, and L61/L75, in addition to exhibiting satisfactory effects of their specific combining ability, also displayed the most favorable phenotypic responses for most agronomic and root traits, making them ideal candidates for inclusion in popcorn breeding programs aiming to develop drought-tolerant genotypes.","PeriodicalId":54759,"journal":{"name":"Journal of Thermal Stresses","volume":"51 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80981202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high mortality rate and ever-changing shape of the virus are the challenging factors in the effective management of SARS-CoV-2. However, in last three years, research communities have made significant progress in developing vaccines and controlling the spread of the pandemic to a certain extent. These vaccines contain the attenuated pathogens, which after application did not kill the virus but protected the human by enhancing the immune system response during pandemic exposure. However, the negative side effects and the high cost of the synthetic vaccines are always of concern for researchers, consumers, and the government. Therefore, as an alternative to synthetic drugs, natural medicines or natural plant products have piqued researchers’ interest. Algae are considered as a treasure house of bioactive compounds such as carotenoids, vitamins, polysaccharides, proteins, etc. These bioactive compounds have been well documented for the treatments of various human ailments such as cancer and cardiovascular diseases. Furthermore, sulfated polysaccharides such as alginate and carrageenan have been reported as having antiviral and immunomodulating properties. Therefore, this review addresses algal polysaccharides, especially alginate and carrageenan, and their application in the treatment of COVID-19. In addition, in silico approaches are discussed for the inhibition of the S1-RBD (receptor-binding domain) of SARS-CoV-2, which attaches to the host receptor ACE2 (angiotensin-converting enzyme 2), and the interaction with the network of relative proteins is also explored, which will help in drug discovery and drug design.","PeriodicalId":54759,"journal":{"name":"Journal of Thermal Stresses","volume":"74 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85960005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The non-local theory is employed to study the wave behavior. Three phase lag model with higher order fractional order derivative is incorporated to discuss heat propagation through the medium, in addition with two phase lags diffusion equation. The Helmholz vector rule is applied to decompose the system into longitudinal and transverse components. The frequency dispersion relation indicates the presence of four coupled longitudinal and one un-coupled shear vertical wave. The speed of the waves is plotted against angular frequency for local and nonlocal medium. The cutoff frequency of the waves is also depicted graphically. The longitudinal P-wave is taken to be an incident wave at the free surface of the solid to compute the reflection coefficients. The influences of fractional order and nonlocal parameters on amplitude ratios are also studied. The effect of these parameters is found to be significant. The results are proved in the context of energy conservation. The results obtained from the current investigation are very useful for scientists working on problems of geophysics and various fields of mechanics.","PeriodicalId":54759,"journal":{"name":"Journal of Thermal Stresses","volume":"46 1","pages":"1022 - 1044"},"PeriodicalIF":2.8,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43389504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
