In recent years, machine learning has gained substantial attention for its ability to predict complex chemical and biological properties, including those of pharmaceutical compounds. This study proposes a machine learning-based quantitative structure-property relationship (QSPR) model for predicting the physicochemical properties of anti-arrhythmia drugs using topological descriptors. Anti-arrhythmic drug development is challenging due to the complex relationship between chemical structure and drug efficacy.

Induced pluripotent stem cell (iPSC)-derived natural killer (NK) cells offer an opportunity for a standardized, off-the-shelf treatment with the potential to treat a wider population of acute myeloid leukaemia (AML) patients than the current standard of care. FT538 iPSC-NKs express a high-affinity, noncleavable CD16 to maximize antibody dependent cellular cytotoxicity, a CD38 knockout to improve metabolic fitness, and an IL-15/IL-15 receptor fusion preventing the need for cytokine administration, the main source of adverse effects in NK cell-based therapies. Here, we sought to evaluate the potential of FT538 iPSC-NKs as a therapy for AML through their effect on AML cell lines and primary AML cells.

Background: Traditional nomograms can inform the presence of extraprostatic extension (EPE) but not laterality, which remains important for surgical planning, and have not fully incorporated multiparametric MRI data. We evaluated predictors of side-specific EPE on surgical pathology including MRI characteristics and developed side-specific EPE risk calculators.

Methods: This was a retrospective cohort of patients evaluated with mpMRI prior to radical prostatectomy (RP) in our eleven hospital healthcare system from July 2018-November 2022.

In this article, we present the concept of extended Seidel energy by employing a generalized extended matrix to study various molecular properties, including the Kovats retention index, boiling point, enthalpy of formation, entropy, acentric factor, and octanol-water partition coefficient. Our research broadens the scope of energy matrices in graph theory, with a particular emphasis on Sombor energy, reduced Sombor energy, average Sombor energy, Banhatti Sombor energy and reduced Banhatti Sombor energy. We examined the correlation of these graph-based energy descriptors with the thermodynamic properties of Benzenoid hydrocarbons (BHC), uncovering strong relationships between these indices and different molecular attributes.

Article Synopsis
  • Appendiceal cancers, particularly mucinous cystadenocarcinoma, are rare and can cause serious complications like pseudomyxoma peritonei, leading to abdominal fluid accumulation called "jelly belly."
  • A case of a young man with a persistent psoas abscess revealed mucinous adenocarcinoma with pseudomyxoma retroperitonei, emphasizing the need to consider malignancy in atypical abscesses.
  • Early and accurate diagnosis is critical because these types of tumors can be misdiagnosed as common issues like abscesses, highlighting the importance of imaging and colonoscopy in identifying them.

Article Synopsis
  • Advances in imaging techniques now allow for earlier and noninvasive diagnosis of hepatocellular carcinoma (HCC) in high-risk patients.
  • Up to 60% of HCC cases show typical imaging features, while 40% do not, creating challenges for radiologists due to diverse morphologic subtypes and their unique molecular characteristics.
  • The article focuses on unusual imaging presentations of HCC and discusses potential diagnostic pitfalls and conditions that may resemble HCC.

The 'Third Pole', home to numerous glaciers, serves as vital water reserves for a significant portion of the Asian population and has garnered global attention within the context of climate change due to their highly vulnerable nature. While a general decline in global glacial extent has been observed in recent decades, the pronounced regional imbalances across the Third Pole present a perplexing anomaly. To assess the impact of glacier mass changes in the Gangotri basin, we conducted a comprehensive analysis using remote sensing data to estimate spatially resolved mass changes from 2000 to 2023.

Objectives Diabetes mellitus type 2 is a chronic metabolic disorder characterized by insulin resistance and progressive beta-cell dysfunction. As diabetes persists over time, more pronounced symptoms like polyuria, polydipsia, fatigue, and complications like neuropathy, retinopathy, and cardiovascular issues may develop. Therefore, this study assessed the clinical symptoms associated with type 2 diabetes regarding the duration of diabetes.

Phthalocyanine derivative nanostructures are highly organized organometallic structures that exhibit two-dimensional polymeric phthalocyanine frameworks. We analyze phthalocyanine using the Zagreb-type indices, which offer important insights into the topological characteristics of the molecular structure. Furthermore, we use Pearson correlation analysis to examine the degree of relationship between various structural features and qualities.

Background Hereditary angioedema (HAE) is a rare disorder in India, and while prevalence data is limited, it is believed that a significant number of individuals may be affected. Due to restricted access to first-line treatments, older therapies like danazol are commonly used despite associated risks in resource-constrained settings. This study aimed to assess the efficacy of danazol as an affordable long-term prophylaxis (LTP) for HAE in a three-generation family.

Background: Clear cell renal cell carcinoma (ccRCC) is a type of cancer characterized by a vast intracellular accumulation of lipids that are critical to sustain growth and viability of the cells in the tumour microenvironment. Stearoyl-CoA 9-desaturase 1 (SCD-1) is an essential enzyme for the synthesis of monounsaturated fatty acids and consistently overexpressed in all stages of ccRCC growth.

Methods: Human clear cell renal cell carcinoma lines were treated with small-molecule inhibitors of protein kinase CK2.

Ventricular arrhythmias (VA) are a major cause of morbidity and mortality in patients with coronary artery disease (CAD). Current guidelines recommend revascularization of significant CAD to improve survival in patients with ventricular fibrillation (VF), polymorphic ventricular tachycardia (VT), or those who are post-cardiac arrest. However, revascularization is not recommended for CAD patients with suspected scar-mediated monomorphic VT.

Background: Childhood obesity is a growing public health issue globally, including in India. Anthropometric measures such as body mass index (BMI), waist circumference, and skinfold thickness are commonly used to estimate body fat percentage (BF%), but their correlations with fat mass (FM) and fat mass index (FMI) are less emphasized. This study aimed to explore the relationships between anthropometric measurements and body fat indicators (BF%, FM, and FMI) in school-age children and obtain prediction equations for FM and FMI.

Metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as a public health threat as it affects approximately 38% of the adult population worldwide, with its prevalence rising in step with that of obesity and type 2 diabetes. Beyond the implications of MASLD for liver health, it is also associated with cardiovascular and vascular dysfunction. Although the many shared risk factors and common metabolic milieu might indicate that cardiovascular disease and MASLD are discrete outcomes from common systemic pathogeneses, a growing body of evidence has identified a potential causal relationship between MASLD and coronary artery disease, which is the leading cause of morbidity and mortality in people with MASLD and all-cause mortality worldwide.

Metabolomics is emerging as a significant approach to reflect the individual's response to pathophysiological conditions. Nuclear magnetic resonance (NMR) spectroscopy has evolved as a tool to identify metabolic dysregulations in critically ill patients afflicted with conditions like acute respiratory distress syndrome (ARDS), severe acute pancreatitis (SAP), acute kidney injury (AKI), and sepsis. The spectral data from the serum sample of the study and control group are recorded using an 800 MHz NMR spectrometer and processed using NMR processing and analysis tools.
