Appraisal of potentially toxic metals contamination in protein supplements for muscle growth: A chemometric approach and associated human health risks.

BACKGROUND: The use of protein supplements by athletes has risen due to their effectiveness in meeting dietary needs. However, there is a growing concern about the presence of potentially toxic metals (PTMs. Al, Cr, Mn, Ni, Cu, Zn, Cd, and Pb) in these supplements. Consequently, it is crucial to evaluate the levels of these PTMs to ensure the safety of the supplements. METHODS: The objective of the current study was to assess the PTMs concentrations in protein supplements and examine any possible health hazards. Twenty-five samples of protein supplements were purchased from different pharmacies to screen them for metals. Inductively coupled plasma-optical emission spectrometry (ICP-OES) was utilized to analyze metal content. Additionally, chemometric methods such as Pearson's correlation coefficient (PCC), principal component analysis (PCA), and hierarchical cluster analysis (HCA) were employed to identify possible sources of PTMs contamination in protein supplements. RESULTS: Concentration ranges for PTMs were found as, Al (0.03-3.05 mg/kg), Cr (0.11-0.89 mg/kg), Mn (1.13-8.40 mg/kg), Ni (0.06-0.71 mg/kg), Cu (1.05-5.51 mg/kg), Zn (2.14-27.10 mg/kg), Cd (0.01-0.78 mg/kg), and Pb (0.06-0.57 mg/kg). The weekly intake of Cd exceeded the level of tolerable weekly intake (TWI) set by the European Food Safety Authority (EFSA). CONCLUSION: Athletes, bodybuilders, fitness enthusiasts, dieters, young adults and adolescents, and health-conscious individuals should be conscious of Cd concentration as it does not compliance the TWI set by EFSA. Target hazard quotient (THQ < 1), hazard index (HI < 1), margin of exposure (MOE ≥ 1), percentile permitted daily exposure (% PDE < 100), and cumulative cancer risk (CCR < 1 × 10-3) analyses revealed that there are no appreciable non-carcinogenic and carcinogenic health risks associated with the use of these products.

Contamination of trace, non-essential/heavy metals in nutraceuticals/dietary supplements: A chemometric modelling approach and evaluation of human health risk upon dietary exposure.

Across the world, nutraceuticals/dietary supplements are commonly consumed without medical supervision, and believing these products are harmless to health. However, these products may contain trace (TMs) and non-essential/heavy metals (nHMs) as contaminants at levels higher than the recommended daily allowance (RDA), which can be hazardous to human health. Consequently, it is crucial to assess the levels of these metals to ensure the safety of these products. This study aimed to analyze the concentration of TMs (Mn, Cu and Zn) and nHMs (Al, Cr, Ni, Cd and Pb) in nutraceuticals/dietary supplements. Metal analysis was conducted using inductively coupled plasma-optical emission spectrometry (ICP-OES). Multivariate and bivariate analysis including principle component analysis (PCA), hierarchical cluster analysis (HCA) and Pearson correlation coefficient (PCC) were applied to understand inter-metal association and sources of these metals. Concentration ranges for TMs were found as, Mn (0.2-4.3 mg/kg), Cu (0.11-2.54 mg/kg), and Zn (0.1-22.66 mg/kg) while the nHMs concentration ranges were: Al (0.046-3.336 mg/kg), Cr (0.11-1.63 mg/kg), Ni (0.18-0.72 mg/kg), Cd (0.04-0.92 mg/kg), and Pb (0.18-1.08 mg/kg). The levels of tolerable dietary intake (TDI) for Cr and Ni, and the provisional tolerable monthly intake (PTMI) limit for Cd, exceeded the values set by the World Health Organization (WHO) and the European Food Safety Authority (EFSA). The estimation of the target hazard quotient (THQ <1), hazard index (HI < 1) and cumulative cancer risk (CCR <1 ✕ 10-3) indicated no significant non-carcinogenic and carcinogenic health risks associated with consuming these products. Therefore, the primary recommendation from this study is to use the nutraceuticals/dietary supplements should be under the supervision of dietitian.

Chemometric Analysis and Human Health Implications of Trace and Heavy/Non-Essential Metals through ingestion of Carbonated and Non-Carbonated Beverages.

Elevated levels of trace metals (TMs) and heavy/non-essential metals (HnMs) in commonly consumed beverages concern the public and regulatory agencies. Thus, frequent monitoring of these metals is critically important. The present study intended to assess TMs and HnMs concentrations and associated health risks in beverages. Ten metals, such as Mn, Co, Cr, Cu, and Zn (TMs) and Ni, Cd, Pb, Al, and As (HnMs), were quantified in different beverage brands categorized into two groups such as non-carbonated and carbonated beverages. Chemometric analysis such as hierarchical cluster analysis (HCA), Pearson's correlation coefficient (PCC), and principal component analysis (PCA) were also performed to demonstrate the possible natural and anthropogenic sources of metal contamination. Among the TMs, the mean concentration of Zn (233.3 ± 3.3-291.7 ± 3.2 µg/L) followed by Mn (119.0 ± 2.3-146.4 ± 2.2 µg/L) was found highest in both carbonated and non-carbonated beverage samples. In the case of HnMs, the lowest mean concentration of Cd (7.4 ± 0.9-18.6 ± 1.2 µg/L) followed by Pb (4.1 ± 0.4-4.5 ± 0.4 µg/L) was observed in both types of beverage samples. The tolerable dietary intake (TDI) value for Ni and provisional tolerable monthly intake (PTMI) value for Cd were higher than the value established by the WHO and EFSA. The computed values of the hazard index (HI < 1) and the cumulative cancer risk (CCR) indicated a low risk of exposure.

Genomic blueprints of soybean (Glycine max) pathogen resistance: revealing the key genes for sustainable agriculture.

Soybean (Glycine max ) is an important oilseed, protein and biodiesel crop. It faces significant threats from bacterial, fungal and viral pathogens, which cause economic losses and jeopardises global food security. In this article, we explore the relationship between soybeans and these pathogens, focusing on the molecular responses that are crucial for soybeans defence mechanisms. Molecular responses involve small RNAs and specific genes, including resistance (R) genes that are pivotal in triggering immune responses. Functional genomics, which makes use of cutting-edge technologies, such as CRISPR Cas9 gene editing, allows us to identify genes that provide insights into the defence mechanisms of soybeans with the focus on using genomics to understand the mechanisms involved in host pathogen interactions and ultimately improve the resilience of soybeans. Genes like GmKR3 and GmVQ58 have demonstrated resistance against soybean mosaic virus and common cutworm, respectively. Genetic studies have identified quantitative trait loci (QTLs) including those linked with soybean cyst nematode, root-knot nematode and Phytophthora root and stem rot resistance. Additionally, resistance against Asian soybean rust and soybean cyst nematode involves specific genes and their variations in terms of different copy numbers. To address the challenges posed by evolving pathogens and meet the demands of a growing population, accelerated soybean breeding efforts leveraging functional genomics are imperative. Targeted breeding strategies based on a deeper understanding of soybean gene function and regulation will enhance disease resistance, ensuring sustainable agriculture and global food security. Collaborative research and continued technological advancements are crucial for securing a resilient and productive agricultural future.

Assessment of carcinogenic and non-carcinogenic risk of exposure to potentially toxic elements in tea infusions: Determination by ICP-OES and multivariate statistical data analysis.

BACKGROUND: The perennial evergreen tea (Camellia sinensis) plant is one of the most popular nonalcoholic drinks in the world. Fertilizers and industrial, agricultural, and municipal activities are the usual drivers of soil contamination, contaminating tea plants with potentially toxic elements (PTEs). These elements might potentially accumulate to larger amounts in the leaves of plants after being taken up from the soil. Thus, frequent monitoring of these elements is critically important. METHODS: The present study intended to determine PTEs (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb) in both tea leaves and infusions using ICP-OES. Various multivariate data analysis methods such as principal component analysis (PCA) and hierarchical cluster analysis (HCA) were employed to elucidate the potential sources of PTEs contamination, whether from anthropogenic activities or natural origins. Additionally, Pearson's correlation coefficient (PCC) was calculated to assess the relationships between the variables under study. RESULTS: The mean contents (mg/L) of all studied elements in tea infusions decreased in order Mn (150.59 ±â€¯1.66) > Fe (11.39 ±â€¯0.99) > Zn (6.62 ±â€¯0.89) > Cu (5.86 ±â€¯0.62) > Co (3.25 ±â€¯0.64) > Ni (1.69 ±â€¯0.23) > Pb (1.08 ±â€¯0.16) > Cr (0.57 ±â€¯0.09) > Cd (0.46 ±â€¯0.09) > Al (0.05 ±â€¯0.008), indicating that Mn exhibits the highest abundance. The mean concentration trend in tea leaf samples mirrored that of infusions, albeit with higher concentrations of PTEs in the former. The tolerable dietary intake (TDI) value for Ni and provisional tolerable monthly intake (PTMI) value for Cd surpassed the standards set by the WHO and EFSA. Calculated hazard index (HI < 1) and cumulative cancer risk (CCR) values suggest negligible exposure risk. CONCLUSION: Elevated levels of PTEs in commonly consumed tea products concern the public and regulatory agencies.

Colour, nutritional composition and antioxidant properties of dehydrated carrot (Daucus carota var. sativus) using solar drying techniques and pretreatments.

Carrot is a seasonal perishable tuberous root vegetable which presents a preservation challenge owing to its elevated moisture content. Recently, carrot processing has received more attention because of its many health-promoting qualities and the reduction of postharvest losses in a cost-effective safe way. This study was designed to sort out the effective solar drying technique including pre-treatment that would retain the color and quality characteristics of dehydrated carrot. Carrot slices were subjected to dry using open sun drying (D1), solar drying long chimney (D2), solar drying short chimney (D3) and box solar drying (D4) techniques with the pretreatments of ascorbic acid 1 % (C3), citric acid 5 % (C4), potassium metabisulfite 1 % (C5) and potassium sodium tartrate 0.3 % (C6) before drying. Drying characteristics, nutritional attributes, phytochemicals and antioxidant of the dehydrated carrot samples were compared with the fresh sample and untreated (control) sample. Results showed that D4 was a good drying method to preserve nutritional quality with good appearance. Among the pretreatments, C5 and C4 resulted improved nutritional quality retention, enhanced visual acceptability and enriched antioxidant activities. PCA (Principal Component Analysis) and correlation matrix revealed that D4 with C5 retained the maximum amount of vitamin, minerals, total phenolic content, antioxidant and admirable dehydrated carrot color by inactivating enzymatic reaction. Therefore, box solar drying with potassium metabisulfite pretreatment would be very promising for functional carrot drying retaining acceptable color and nutrition composition.

Frequency and association of Epstein-Barr Virus genotype in rheumatoid arthritis patients of Khyber Pakhtunkhwa, Pakistan.

BACKGROUND: Rheumatoid arthritis (RA) is an immune-mediated, polyarthritis linked with various genetic and environmental causative agents. Among environmental triggers, Epstein-Barr Virus (EBV) is considered the most potent etiological agent. OBJECTIVE: This study aimed to investigate the prevalence of EBV and its genotypes in RA patients and to investigate their association with clinical and laboratory parameters of RA. METHODOLOGY: This study included blood samples of RA and control healthy individuals (100 each). Blood samples along with clinical and laboratory parameters were collected from patients after consent in the Department of Rheumatology, at Lady Reading Hospital, in Peshawar Pakistan. Blood samples were processed for DNA extraction followed by PCR amplification for EBV detection and genotype discrimination. RESULTS: RA patients were 85 females and 15 males with a mean age of 40.13±14.05 years. EBV Type-1 was detected in 45% of RA and 9% of control cases. The mean disease duration of RA patients was 6.61±6.23 years. Out of 100 diseased patients, 43% were seropositive rheumatoid arthritis (SPRA) and showed a significant correlation with a family history of RA in EBV-positive individuals (P = 0.017). The demographic, clinical, and laboratory parameters of RA patients showed a non-significant association with EBV. Moreover, only a family history and Serum creatinine of RA patients showed a significant association with EBV (P = 0.0001 and P = 0.022 respectively). CONCLUSION: It is concluded that EBV-1 is prevalent and associated with RA. Further investigation is required for detailed genetic analysis of EBV to determine its possible role in modulating the immune system in RA.

Silicon nanoparticles alleviate cadmium toxicity in rice (Oryza sativa L.) by modulating the nutritional profile and triggering stress-responsive genetic mechanisms.

This study investigated the physiological and molecular responses of rice genotype '9311' to Cd stress and the mitigating effects of silicon oxide nanoparticles (SiO NPs). Cd exposure severely hindered plant growth, chlorophyll content, photosynthesis, and Cd accumulation. However, SiO NPs supplementation, particularly the SiONP100 treatment, significantly alleviated Cd-induced toxicity, mitigating the adverse effects on plant growth while maintaining chlorophyll content and photosynthetic attributes. The SiONP100 treatment also reduced Cd accumulation, indicating a preference for Si uptake in genotype 9311. Complex interactions among Cd, Si, Mg, Ca, and K were uncovered, with fluctuations in MDA and H2O2 contents. Distinct morphological changes in stomatal aperture and mesophyll cell structures were observed, including changes in starch granules, grana thylakoids, and osmophilic plastoglobuli. Moreover, following SiONP100 supplementation, genotype 9311 increased peroxidase, superoxide dismutase, and catalase activities by 56%, 44%, and 53% in shoots and 62%, 49%, and 65% in roots, respectively, indicating a robust defense mechanism against Cd stress. Notably, OsNramp5, OsHMA3, OsSOD-Cu/Zn, OsCATA, OsCATB, and OsAPX1 showed significant expression after SiO NPs treatment, suggesting potential Cd translocation within rice tissues. Overall, SiO NPs supplementation holds promise for enhancing Cd tolerance in rice plants while maintaining essential physiological functions.

Radial Artery Harvesting With Skin Bridge Technique Among Patients Undergoing Coronary Artery Bypass Grafting: An Approach For Developing Countries.

The risk of wound dehiscence and sternal infections remains high after coronary artery bypass grafting, especially in patients with diabetes. Radial artery is a potential alternative which has shown good post-operative outcomes with least complications. Open and endoscopic techniques for harvesting have been used till now. We propose an interrupted or bridging technique, for harvesting the radial artery. This report describes 25 patients undergoing CABG, using radial artery graft, harvested via skin bridge technique, at South City Hospital, Karachi. It has a better cosmetic outcome, reduced postoperative pain, shortened hospital stay and increased level of satisfaction. The interrupted technique offers less invasive cost-effective approach compared to open and endoscopic techniques for radial artery harvesting.

Exposure Assessment of Essential and Potentially Toxic Metals in Wheat-Based Sweets for Human Consumption: Multivariate Analysis and Risk Evaluation Studies.

In recent years, there has been a growing concern about the negative impact of unforeseen contaminants such as metals in commonly consumed food items, which pose a threat to human well-being. Therefore, it is of utmost importance to evaluate the levels of these contaminants to guarantee the safe consumption of these food items. The goal of the current research is to determine the levels of essential (EMs: Mg, Ca, Mn, Fe, Co, Cu, and Zn) and potentially toxic metals (PTMs: Al, Cr, Ni, As, Cd, and Pb) in various brands of wheat-based sweets. One hundred samples were collected and analysed via flame atomic absorption spectrometry (FAAS) and inductively coupled plasma-optical emission spectrometry (ICP-OES). Also, the current study was to investigate the distribution, correlation, and multivariate analysis of 13 metals (Mg, Ca, Mn, Fe, Co, Cu, Zn, Al, Cr, Ni, As, Cd, and Pb). Hierarchical cluster analysis (HCA) and principal component analysis (PCA) were used to interpret the metals' association. The concentration (mg/kg) ranges of EMs were, in order, Mg (12.70-65.67), Ca (24.02-209.12), Mn (1.32-9.61), Fe (4.55-111.23), Co (0.32-8.94), Cu (2.12-8.61), and Zn (2.60-19.36), while the concentration (mg/kg) ranges of PTMs were, in order, Al (0.32-0.87), Cr (0.17-5.74), Ni (0.36-1.54), Cd (0.16-0.56), and Pb (0.14-0.92), and As was not detected in any sample under investigation. The HCA data revealed that Co, Al, and Ni form clusters with other metals. Sweets are prepared at high temperatures, and the elevated temperatures can increase the likelihood of Ni and Al leaching from stainless steel. Tolerable dietary intake (TDI) values for Ni were higher than the values established by the European Food Safety Authority (EFSA). The CR value found for the Ni and Cr was at the threshold level of cancer risk, if an amount of 25 g were to be used over a lifetime. In a nutshell, this study highlights the monitoring of EM and PTM levels in wheat-based sweets, and from a food safety perspective, the study is important for consumers of wheat-based sweets.

COVID-19 fear and its associated correlates among type-2 diabetes patients in Bangladesh: A hospital-based study.

The outbreak of COVID-19 has caused widespread fear among people around the world, particularly those with underlying health conditions such as type-2 diabetes. This study aimed to investigate COVID-19 fear and its associated potential factors among type-2 diabetes patients in Bangladesh. A total of 1,036 type-2 diabetes patients residing in the Jashore district of Bangladesh were interviewed using the COVID-19 Fear Scale in Bengali language. A pre-validated questionnaire was used to collect data on sociodemographic, lifestyle-related characteristics, and COVID-19-related information. Logistic regression was performed to identify factors associated with perceived fear of COVID-19. The mean score of the COVID-19 fear was 18.1 ± 5.6. Approximately 45 and 39% were most afraid and uncomfortable thinking about COVID-19, respectively. Regression analysis revealed that gender, age, occupation, residence, physical activity, smoking, and dietary diversity score were associated with fear. Additionally, respondents who had limited self-care practice, unaffordable medicine, medicine shortages, a close friend or family member diagnosed with COVID-19, and financial problems during COVID-19 were significant predictors of COVID-19 fear. Healthcare providers should implement interventions, including appropriate education and counseling, to address the psychological impact of the COVID-19 pandemic on type-2 diabetes patients in Bangladesh.

Atezolizumab Induces Necroptosis and Contributes to Hepatotoxicity of Human Hepatocytes.

Atezolizumab is an immune checkpoint inhibitor (ICI) targeting PD-L1 for treatment of solid malignancies. Immune checkpoints control the immune tolerance, and the adverse events such as hepatotoxicity induced by ICIs are often considered as an immune-related adverse event (irAE). However, PD-L1 is also highly expressed in normal tissues, e.g., hepatocytes. It is still not clear whether, targeting PD-L1 on hepatocytes, the atezolizumab may cause damage to liver cells contributing to hepatotoxicity. Here, we reveal a novel mechanism by which the atezolizumab induces hepatotoxicity in human hepatocytes. We find that the atezolizumab treatment increases a release of LDH in the cell culture medium of human hepatocytes (human primary hepatocytes and THLE-2 cells), decreases cell viability, and inhibits the THLE-2 and THLE-3 cell growth. We demonstrate that both the atezolizumab and the conditioned medium (T-CM) derived from activated T cells can induce necroptosis of the THLE-2 cells, which is underscored by the fact that the atezolizumab and T-CM enhance the phosphorylation of RIP3 and MLKL proteins. Furthermore, we also show that necrostatin-1, a necrosome inhibitor, decreases the amount of phosphorylated RIP3 induced by the atezolizumab, resulting in a reduced LDH release in the culture media of the THLE-2 cells. This finding is further supported by the data that GSK872 (a RIP3 inhibitor) significantly reduced the atezolizumab-induced LDH release. Taken together, our data indicate that the atezolizumab induces PD-L1-mediated necrosome formation, contributing to hepatotoxicity in PD-L1+-human hepatocytes. This study provides the molecular basis of the atezolizumab-induced hepatotoxicity and opens a new avenue for developing a novel therapeutic approach to reducing hepatotoxicity induced by ICIs.

Targeting endothelial permeability in the EPR effect.

The characteristics of the primary tumor blood vessels and the tumor microenvironment drive the enhanced permeability and retention (EPR) effect, which confers an advantage towards enhanced delivery of anti-cancer nanomedicine and has shown beneficial effects in preclinical models. Increased vascular permeability is a landmark feature of the tumor vessels and an important driver of the EPR. The main focus of this review is the endothelial regulation of vascular permeability. We discuss current challenges of targeting vascular permeability towards clinical translation and summarize the structural components and mechanisms of endothelial permeability, the principal mediators and signaling players, the targeted approaches that have been used and their outcomes to date. We also critically discuss the effects of the tumor-infiltrating immune cells, their interplay with the tumor vessels and the impact of immune responses on nanomedicine delivery, the impact of anti-angiogenic and tumor-stroma targeting approaches, and desirable nanoparticle design approaches for greater translational benefit.

Correlation Between Serum Tumor Necrosis Factor-Alpha (TNF-α) and Clinical Severity of Tuberculosis: A Hospital-Based Study.

AIM: The main aim of this study was to assess the correlation between serum tumor necrosis factor-alpha (TNF-α) levels the and clinical severity of tuberculosis. METHODS: This was a hospital-based case-control prospective study and was conducted at the Sher-i-Kashmir Institute of Medical Sciences, a tertiary care hospital in the northern part of India, from May 2016 to May 2018. The subjects were recruited in the study considering inclusion and exclusion criteria. All patients with pulmonary tuberculosis as well as patients with extrapulmonary tuberculosis were included as subjects and a clinical severity score based on anemia, weight loss, presence of hypoxia, and radiological features was calculated and compared with TNF-α levels. Age- and sex-matched healthy individuals were recruited as controls. RESULTS: A total of 75 subjects comprising 50 cases and 25 controls were taken for the study. There were 34 (68.0%) patients with elevated TNF-α levels while only 16 (32.0%) patients had normal TNF-α levels. And, TNF-α levels were normal in 21 (84%) control subjects as compared to tuberculosis (TB) patients. Such difference in serum TNF-α levels between cases and controls was statistically significant (p<0.05). The mean serum TNF-α level in TB cases was 1265.63 pg/mL, while the mean serum TNF-α level in controls was 312.06 pg/mL. The difference in serum TNF-α levels between the two groups was statistically significant (p<0.01). We observed a significant increase in serum TNF-α levels with the increase in clinical severity score. CONCLUSION: Serum TNF-α levels were significantly associated with increased severity of TB.

Patent foramen Ovale-related paradoxical embolism after noncardiac surgery.

Patent foramen ovale (PFO) is a remnant of the fetal circulation that remains in a significant portion of the adult population, predisposing to a higher risk of stroke. This risk is further elevated in the postoperative hypercoagulative period. Here we present a case where a patient underwent a total knee arthroplasty and presented with right-sided hemiparesis on post-operative day 2. Subsequently, the patient underwent percutaneous PFO closure with a 25-mm Amplatzer PFO Occluder (Abbott; Chicago, IL, USA). The patient has not had a stroke since the PFO closure. Recent randomized trials have demonstrated superiority of percutaneous PFO closure over standard-of-care medical therapy for secondary prevention of PFO-associated stroke. Since post-operative PFO-associated stroke is under-recognized in clinical practice, further large-cohort studies are needed to evaluate whether PFO screening and device closure would decrease post-operative stroke risk for noncardiac surgeries. Learning Objective: Patent foramen ovale (PFO) is a remnant of the fetal circulation commonly found in the adult population, which can increase the risk of stroke. Stroke is a complication of PFO, yet closure of this remnant only occurs on a specific case-by-case basis. Further research in this area is required to determine whether a larger population would benefit from PFO closure.

Iron-selenide-based titanium dioxide nanocomposites as a novel electrode material for asymmetric supercapacitors operating at 2.3 V.

This study portrays a facile wet-chemical synthesis of FeSe2/TiO2 nanocomposites for the first time for advanced asymmetric supercapacitor (SC) energy storage applications. Two different composites were prepared with varying ratios of TiO2 (90 and 60%, symbolized as KT-1 and KT-2) and their electrochemical properties were investigated to obtain an optimized performance. The electrochemical properties showed excellent energy storage performance owing to faradaic redox reactions from Fe2+/Fe3+ while TiO2 due to Ti3+/Ti4+ with high reversibility. Three-electrode designs in aqueous solutions showed a superlative capacitive performance, with KT-2 performing better (high capacitance and fastest charge kinetics). The superior capacitive performance drew our attention to further employing the KT-2 as a positive electrode to fabricate an asymmetric faradaic SC (KT-2//AC), exceeding exceptional energy storage performance after applying a wider voltage of 2.3 V in an aqueous solution. The constructed KT-2/AC faradaic SCs significantly improved electrochemical parameters such as capacitance of 95 F g-1, specific energy (69.79 Wh kg-1), and specific power delivery of 11529 W kg-1. Additionally, extremely outstanding durability was maintained after long-term cycling and rate performance. These fascinating findings manifest the promising feature of iron-based selenide nanocomposites, which can be effective electrode materials for next-generation high-performance SCs.

Entropy Related to K-Banhatti Indices via Valency Based on the Presence of C6H6 in Various Molecules.

Entropy is a measure of a system's molecular disorder or unpredictability since work is produced by organized molecular motion. Shannon's entropy metric is applied to represent a random graph's variability. Entropy is a thermodynamic function in physics that, based on the variety of possible configurations for molecules to take, describes the randomness and disorder of molecules in a given system or process. Numerous issues in the fields of mathematics, biology, chemical graph theory, organic and inorganic chemistry, and other disciplines are resolved using distance-based entropy. These applications cover quantifying molecules' chemical and electrical structures, signal processing, structural investigations on crystals, and molecular ensembles. In this paper, we look at K-Banhatti entropies using K-Banhatti indices for C6H6 embedded in different chemical networks. Our goal is to investigate the valency-based molecular invariants and K-Banhatti entropies for three chemical networks: the circumnaphthalene (CNBn), the honeycomb (HBn), and the pyrene (PYn). In order to reach conclusions, we apply the method of atom-bond partitioning based on valences, which is an application of spectral graph theory. We obtain the precise values of the first K-Banhatti entropy, the second K-Banhatti entropy, the first hyper K-Banhatti entropy, and the second hyper K-Banhatti entropy for the three chemical networks in the main results and conclusion.

Iatrogenic ANA: An emerging source of expensive diagnostic confusion.

Intravenous immune globulin (IVIg) therapy has been shown to be useful in a multitude of disorders. IVIg is produced from pooled human plasma; therefore, autoantibodies found in the general population are also present in IVIg and transferred to those being transfused. This can prove a particular hazard for screening and diagnostic tests based on autoantibodies. We present a patient who was found to have a positive antinuclear antibody (ANA) titer after multiple IVIg transfusions, resulting in diagnostic confusion and unnecessary workup. A 45-year-old gentleman was diagnosed with atypical CIDP, initiated on a course of IVIg, and sent for inpatient rehabilitation. However, recovery was complicated by multiple readmissions for recurrent weakness, and as part of the workup for other etiologies, an ANA was found to be positive. Sub-serologies and paraneoplastic autoantibody panel were negative. In the absence of clinical symptoms, we recommended continued monitoring and repeat ANA testing 6 months after the last dose of IVIg; as any drug needs 5 half-lives to be eliminated from the body. Clinicians should consider any recent IVIg treatments when evaluating the pre-test probability of detecting an underlying connective tissue disease with ANA screening. Indiscriminate ANA levels in patients recently given IVIg lead to unnecessary and expensive further testing and consultation.

Pancreatic Neuroendocrine Tumor (PNET) Presenting as a Pseudocyst: A Case Report.

Pancreatic neuroendocrine tumors (PNETs) account for a very small proportion of all pancreatic tumors. The presence or absence of a specific clinical manifestation associated with hormone oversecretion determines whether a PNET is functional or nonfunctional. Imaging expressions differ significantly, from the common to the extremely rare. Diffuse, uniform pancreatic enlargement, without abnormalities in contour or a central mass, is the most common radiological finding. We report the case of a 43-year-old male who presented with abdominal pain and early satiety over the course of two months and was found to have a non-functioning pancreatic neuroendocrine tumor, with the pseudocyst being the initial diagnostic finding. In comparison to patients with exocrine pancreatic cancer, those with PNET have a much better prognosis and longer expected survival time. This case report highlights the importance of the diagnostic evaluation of PNET and timely intervention to prolong the survival of the patient.
