The strategic design, synthesis and thorough characterization of four novel hydroxyl-substituted tetraphenylimidazole (HPI) based boron dipyrromethene (BODIPY) fluorophores (
HPIB1-HPIB4
) have been ...reported. Single crystal X-ray structure determination unveiled non-planar twisted orientations for these molecules. The non-planar orientations entirely restrict detrimental π-π interactions and avoid the non-radiative relaxation pathway for excited states in the solid/aggregated state and make them AIE active. The AIE characteristics of these compounds have been related to fine J-aggregation (evident from their crystal structures) along with restricted intra-molecular rotations (RIRs). These compounds display significant sensitivity toward viscosity and can serve as fluorescent molecular rotors due to multiple phenyl groups around the imidazole ring, which has been confirmed by measuring fluorescence quantum yields and lifetimes.
In this work, we present tetraphenylimidazole-based BODIPYs (
HPIB1-HPIB4
) as fluorescent molecular rotors exhibiting aggregation induced emission, solid state fluorescence and appreciable sensitivity towards viscosity.

There has been tremendous interest in blockchain technology (BT) (also known as distributed ledger technology) around the globe and across sectors. Following significant success in the financial ...sector, other sectors, such as humanitarian sector, have started deploying BT at various levels. Although the use of BT in the humanitarian sector is in its infancy, donors and government agencies are increasingly calling for building BT-enabled swift-trust (ST) and more collaborative relationships among various humanitarian actors in order to improve the transparency and traceability of disaster relief materials, information exchanges and flow of funds in disaster relief supply chains. Our study, which is informed by organisational information processing theory and relational view, proposes a theoretical model to understand how BT can influence operational supply chain transparency (OSTC) and ST among actors engaged in disaster relief operations. Our model also shows how BT-enabled ST can further improve collaboration (CO) among actors engaged in disaster relief operations and enhance supply chain resilience (SCR). We formulated and tested six research hypotheses, using data gathered from international non-governmental organisations with the help of the Coordinator for Humanitarian Affairs (OCHA) database. We received 256 usable responses using a pre-tested survey-based instrument designed for key informants. Our results confirm that our six hypotheses were supported. Our study offers significant and valid contributions to the literature on ST, CO and SCR and BT/distributed ledger technology. We have also noted the limitations of our study and have offered future research directions.

Hyperhomocysteinemia is a rare condition which predisposes to arterial and venous thrombosis. Plasma homocysteine levels are influenced by many genetic factors and environmental factors. Increased ...levels of homocysteine at high-altitude areas (HAA) can predispose to upper-extremity deep-vein thrombosis (UEDVT). Therefore, awareness by the medical authorities regarding this entity at HAA as a sole cause of UEDVT needs to be established. Prompt reduction in the homocysteine level can be therapeutic as well as prophylactic in preventing the morbidity.
Thiol metabolism is the primary detoxification strategy by which rice plants tolerate arsenic (As) stress. In light of this, it is important to understand the importance of harmonised thiol ...metabolism with As accumulation and tolerance in rice plant. For this aim, tolerant (T) and sensitive (S) genotypes were screened from 303 rice (
Oryza sativa
) genotypes on exposure to 10 and 25 μM arsenite (As
III
) in hydroponic culture. On further As accumulation estimation, contrasting (13-fold difference) T (IC-340072) and S (IC-115730) genotypes were selected. This difference was further evaluated using biochemical and molecular approaches to understand involvement of thiolic metabolism
vis-a-vis
As accumulation in these two genotypes. Various phytochelatin (PC) species (PC

, PC
3
and PC
4
) were detected in both the genotypes with a dominance of PC
3
. However, PC concentrations were greater in the S genotype, and it was noticed that the total PC (PC

)–to–As
III
molar ratio (PC-SH:As
III
) was greater in T (2.35 and 1.36 in shoots and roots, respectively) than in the S genotype (0.90 and 0.15 in shoots and roots, respectively). Expression analysis of several metal(loid) stress–related genes showed significant upregulation of glutaredoxin, sulphate transporter, and ascorbate peroxidase in the S genotype. Furthermore, enzyme activity of phytochelatin synthase and cysteine synthase was greater on As accumulation in the S compared with the T genotype. It was concluded that the T genotype synthesizes adequate thiols to detoxify metalloid load, whereas the S genotype synthesizes greater but inadequate levels of thiols to tolerate an exceedingly greater load of metalloids, as evidenced by thiol-to-metalloid molar ratios, and therefore shows a phytotoxicity response.

Background and Aims: Troops deployed at high-altitude area (HAA) suffer from various high-altitude illnesses (HAIs) including high-altitude pulmonary edema (HAPE). There are various criteria to ...diagnose and assess the severity of HAPE, but point-of-care ultrasound (POCUS) of the lung has also been used in isolation by physicians. The aim is to assess whether POCUS of the lung improves the ability to diagnose the severity of HAPE. Methodology: A retrospective, cross-sectional descriptive study was planned for the patients treated for HAPE (n = 46) at our hospital from January 2019 to March 2020. Prehospital admission data, hospital admission data, and discharge data for the first-time inductees and reinductees were collected from the central hospital admission registry and central database of the medical department and intensive care unit. Results: The incidence of HAPE was 2.2 per 1000. First-time inductees (n = 30) were affected more when compared to reinductees (n = 16) and the maximum were at the third stage of HAA. POCUS of the lung facilitated the diagnosis of the six patients with mild HAPE with no positive radiological features. Conclusions: POCUS of the lung should be routinely used by the medical officers deployed at high altitudes. It will increase the diagnostic rate of HAPE with meticulous grading of the severity, thereby aiding in formulating the case-specific treatment protocol.

Abstract
Chatbots incorporate various behavioral and psychological marketing elements to satisfy customers at various stages of their purchase journey. This research follows the foundations of the ...Elaboration Likelihood Model (ELM) and examines how cognitive and peripheral cues impact experiential dimensions, leading to chatbot user recommendation intentions. The study introduced warmth and competence as mediating variables in both the purchase and postpurchase stages, utilizing a robust explanatory sequential mixed‐method research design. The researchers tested and validated the proposed conceptual model using a 3 × 3 factorial design, collecting 354 responses in the purchase stage and 286 responses in the postpurchase stage. In the second stage, they conducted in‐depth qualitative interviews (Study 2) to gain further insights into the validity of the experimental research (Study 1). The results obtained from Study 1 revealed that “cognitive cues” and “competence” significantly influence recommendation intentions among chatbot users. On the other hand, “peripheral cues” and warmth significantly contribute to positive experiences encountered during the purchase stage. The researchers further identified 69 thematic codes through exploratory research, providing a deeper understanding of the variables. Theoretically, this study extends the ELM by introducing new dimensions to human‐machine interactions at the heart of digital transformation. From a managerial standpoint, the study emphasizes the significance of adding a “humanness” element in chatbot development to create more engaging and positive customer experiences actively.
