Purpose: The human capital in banks is an invaluable asset towards driving innovation and customer success and providing an edge over the competition. However, post-COVID-19 pandemic, rapid adoption of Information and Communication Technologies (ICTs) in Indian banks has increased employee technostress, resulting in adverse job outcomes. This study merges perspectives from psychology, information technology, and organisational behaviour to explore the impact of technostress and leader-member exchange (LMX) on innovative work behaviour (IWB), demonstrating the necessity of a cross-disciplinary approach to address contemporary workplace challenges.

Neuroimaging of cerebral neoplastic lesions and post-radiation necrosis (PRN) presents significant challenges due to their overlapping features, making differentiation difficult. The use of various imaging modalities in association with radiation therapy introduces potential risks and prognostic variations that can affect lesion physiology. Patients who undergo radiation treatment inevitably experience changes influenced by factors such as radiation dose, brain volume, and tumor fraction size.

This guideline addresses the use of hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs) in patients >18 years with chronic kidney disease (CKD) and anemia in South Asia (Bangladesh, Bhutan, Nepal, India, Pakistan, Sri Lanka). It also summarizes recommendations for anemia treatment for individual HIF-PHI molecules under two categories: dialysis-dependent and non-dialysis-dependent CKD patients. The recommendations do not apply to pediatric (≤12 years) and adolescent (12 to 18) patients or those with primary anemia or anemia secondary to other causes such as blood loss, cancer (any type), polycystic kidney disease and infectious diseases.

Climate change will alter the geographical locations most suited for crop production, but adaptation to these new conditions may be constrained by edaphic and socio-economic factors. Here we investigate climate change adaptation constraints in banana, a major export crop of Latin America and the Caribbean. We derived optimal climatic, edaphic and socio-economic conditions from the distribution of intensive banana production across Latin America and the Caribbean, identified using remote sensing imagery.

Background: Deep brain stimulation (DBS) of the bilateral subthalamic nuclei (STN) or globus pallidus internus (GPi) for Parkinson's disease (PD) and dystonia is known for its efficacy despite potential complications. Although acute complications such as intracranial hemorrhage and infections are documented, delayed occurrences like normal pressure hydrocephalus (NPH) post-DBS has not been reported so far.

Cases: We present a case series of seven PD patients (from 974) who developed NPH, an average of 10.

The retention, stability, and function of a complete denture require the presence of adequate width of attached keratinized tissue and vestibular depth. Pre-prosthetic surgical procedures are performed to fulfil these requirements for long-term success. The Edlan-Mejchar vestibuloplasty technique addresses challenges posed by mandibular ridge atrophy and insufficient vestibular depth in edentulous patients.

Ankyloglossia, commonly known as tongue-tie, is a congenital condition characterized by a short, thick lingual frenum that restricts tongue mobility, leading to functional and developmental issues. Surgical intervention, such as a lingual frenectomy, is commonly used to restore tongue function. However, postoperative complications like hematomas can pose significant risks.

Introduction: Health insurance coverage can serve as protection against catastrophic health expenditures. Section 21 (4) of the Mental Healthcare Act, 2017 (MHCA) mandates insurance coverage for mental illness to be on par with that for physical illness. Despite this, anecdotal evidence shows persons with mental health conditions are routinely denied or face difficulties in obtaining medical insurance coverage due to their mental illness.

Chronic lymphedema is a progressive, disfiguring disease that results from dysfunction of the lymphatic vasculature, causing distal accumulation of interstitial fluid, localized development of tissue edema, and expansion of subcutaneous adipose tissue (SAT). As the molecular mechanisms governing SAT remodeling in this disease are unclear, we performed single-nucleus RNA sequencing on paired control and affected SAT biopsies from patients with unilateral lymphedema. Lymphedema samples were characterized by expansion of SAA adipocytes, pro-adipogenic stem cells, and proliferation of lymphatic capillaries.

The triple advancement flap has traditionally been used on the trunk, but gained popularity for facial defects of the neck and temple. Advantages of this closure technique include evenly dispersed tension vectors, less need for extensive subcutaneous undermining and mobilization compared to standard facial reconstruction techniques. The nasal sidewall, root, and bridge often pose reconstructive challenges, with convergence of competing tension lines and surrounding anatomic landmarks.

Artificial Intelligence is expected to be a value-adding intervention in HRM processes; however, there is still a large gap between its perception of value-addition and its actual utility. In this article, we utilize transaction cost and resource-based views to build a framework to assess the suitability and potential adoption of AI-based tools in specific HRM processes. AI-based tools add value when they streamline operations and bring efficiencies by automating repetitive tasks.

Pyridoxic acid (PDA) was suggested as a potential endogenous biomarker to assess in vivo renal organic anion transporter (OAT) 1 and 3 activity. Here, we first investigated the population variability in the plasma baseline levels of PDA using data from five independent studies (conducted/supported by Pfizer), and subsequently developed mechanistic physiologically based pharmacokinetic (PBPK) model to assess its effectiveness in biomarker-informed drug-drug interaction (DDI) predictions. Meta-analysis suggested that the inter-individual variability in PDA plasma concentration was ~40% across all five studies (n = 71 subjects).

Adiabatic passage in systems of interacting bosons is substantially affected by interactions and interparticle entanglement. We consider stimulated raman-adiabatic-passage-like schemes in Bose-Hubbard chains that exhibit low-dimensional chaos (a three-site chain) and high-dimensional chaos (more than three sites). The dynamics that is generated by a transfer protocol exhibits striking classical and quantum chaos fingerprints that are manifested in the mean-field classical treatment, in the truncated Wigner semiclassical treatment, and in the full many-body quantum simulations.

Borderline personality disorder (BPD) is characterized by frequent and intense conflict in intimate relationships. Emerging theoretical perspectives have suggested that communication from both individuals with BPD and their partners during times of conflict may exacerbate BPD pathology and therefore reflect an important target for intervention. Communication samples between individuals with BPD and their partners (N = 18 couples) who were seeking conjoint therapy were coded using the Rapid Marital Interactions Coding System-2.

In breast cancer (BC), radial alignment of collagen fibers at the tumor-matrix interface facilitates collective invasion of cancer cells into the surrounding stromal matrix, a critical step toward metastasis. Collagen remodeling is driven by proteases and cellular forces, mediated by matrix mechanical plasticity, or irreversible matrix deformation in response to force. However, the specific mechanisms causing collagen radial alignment remain unclear.
