Abstract
Reperfusion after acute myocardial infarction further exaggerates cardiac injury and adverse remodeling. Irrespective of cardiac cell types, loss of specifically the α isoform of the protein kinase GSK-3 is protective in chronic cardiac diseases. However, the role of GSK-3α in clinically relevant ischemia/reperfusion (I/R)-induced cardiac injury is unknown. Here, we challenged cardiomyocyte-specific conditional GSK-3α knockout (cKO) and littermate control mice with I/R injury and investigated the underlying molecular mechanism using an in vitro GSK-3α gain-of-function model in AC16 cardiomyocytes post-hypoxia/reoxygenation (H/R). Analysis revealed a significantly lower percentage of infarct area in the cKO vs. control hearts post-I/R. Consistent with in vivo findings, GSK-3α overexpression promoted AC16 cardiomyocyte death post-H/R which was accompanied by an induction of reactive oxygen species (ROS) generation. Consistently, GSK-3α gain-of-function caused mitochondrial dysfunction by significantly suppressing mitochondrial membrane potential. Transcriptomic analysis of GSK-3α overexpressing cardiomyocytes challenged with hypoxia or H/R revealed that NOD-like receptor (NLR), TNF, NF-κB, IL-17, and mitogen-activated protein kinase (MAPK) signaling pathways were among the most upregulated pathways. Glutathione and fatty acid metabolism were among the top downregulated pathways post-H/R. Together, these observations suggest that loss of cardiomyocyte-GSK-3α attenuates cardiac injury post-I/R potentially through limiting the myocardial inflammation, mitochondrial dysfunction, and metabolic derangement. Therefore, selective inhibition of GSK-3α may provide beneficial effects in I/R-induced cardiac injury and remodeling. KEY MESSAGES: GSK-3α promotes cardiac injury post-ischemia/reperfusion (I/R). GSK-3α regulates inflammatory and metabolic pathways post-hypoxia/reoxygenation (H/R). GSK-3α overexpression upregulates NOD-like receptor (NLR), TNF, NF-kB, IL-17, and MAPK signaling pathways in cardiomyocytes post-H/R. GSK-3α downregulates glutathione and fatty acid metabolic pathways in cardiomyocytes post-H/R.

Abstract
Sex determination or sex estimation from a single or fragment of bone is always difficult in the absence of other bones from the same individual. The current study was an attempt to estimate the sex of an individual from the posterior ramus of mandible or the mandibular ramus flexure. A retrospective study was conducted using orthopantomographs (OPGs) of 200 males and 200 females between the age group of 20 - 70 years. Each radiographic image was examined for the presence of a flexure or notching on the posterior border of the ramus in relation to occlusal plane as the method followed by Loth & Henneberg 1996.The study resulted in samples that were correctly classified as females 59.5% and males 57.5 %. The overall correct sex estimation was achieved in 58.5% of the cases. The predictive accuracy or assessment was higher for females compared to males. Consequently, the posterior ramus of mandible or mandibular ramus flexure can be considered as supplementary rather than a definitive means of sex determination. Hence, it is preferable to include as many parameters as possible to attain optimal accuracy.

Abstract
Ischemia-induced metabolic remodeling plays a critical role in the pathogenesis of adverse cardiac remodeling and heart failure however, the underlying molecular mechanism is largely unknown. Here, we assess the potential roles of nicotinamide riboside kinase-2 (NRK-2), a muscle-specific protein, in ischemia-induced metabolic switch and heart failure through employing transcriptomic and metabolomic approaches in ischemic NRK-2 knockout mice. The investigations revealed NRK-2 as a novel regulator of several metabolic processes in the ischemic heart. Cardiac metabolism and mitochondrial function and fibrosis were identified as top dysregulated cellular processes in the KO hearts post-MI. Several genes linked to mitochondrial function, metabolism, and cardiomyocyte structural proteins were severely downregulated in the ischemic NRK-2 KO hearts. Analysis revealed significantly upregulated ECM-related pathways which was accompanied by the upregulation of several key cell signaling pathways including SMAD, MAPK, cGMP, integrin, and Akt in the KO heart post-MI. Metabolomic studies identified profound upregulation of metabolites mevalonic acid, 3,4-dihydroxyphenylglycol, 2-penylbutyric acid, and uridine. However, other metabolites stearic acid, 8,11,14-eicosatrienoic acid, and 2-pyrrolidinone were significantly downregulated in the ischemic KO hearts. Taken together, these findings suggest that NRK-2 promotes metabolic adaptation in the ischemic heart. The aberrant metabolism in the ischemic NRK-2 KO heart is largely driven by dysregulated cGMP and Akt and mitochondrial pathways. KEY MESSAGES: Post-myocardial infarction metabolic switch critically regulates the pathogenesis of adverse cardiac remodeling and heart failure. Here, we report NRK-2 as a novel regulator of several cellular processes including metabolism and mitochondrial function post-MI. NRK-2 deficiency leads to downregulation of genes important for mitochondrial pathway, metabolism, and cardiomyocyte structural proteins in the ischemic heart. It was accompanied by upregulation of several key cell signaling pathways including SMAD, MAPK, cGMP, integrin, and Akt and dysregulation of numerous metabolites essential for cardiac bioenergetics. Taken together, these findings suggest that NRK-2 is critical for metabolic adaptation of the ischemic heart.

Abstract
The fundamental objective of pulp treatment is to preserve the integrity and health of oral tissues. Pulp necrosis or irreversible pulpitis is the key indication for performing pulpectomy in primary teeth. It can be performed as a single-visit or multi-visit procedure using suitable obturating material. Various obturating materials can be used like zinc-oxide eugenol or metapex. A controversy reflects in literature and among experts in regard to single-visit or multi-visit endodontics. Hence, the purpose of this randomized clinical trial is to assess the incidence of postoperative pain with zinc oxide eugenol and metapex as an obturating material in single-visit and multiple-visit pulpectomy. The study was conducted at M S Ramaiah Dental College and Hospital, Bangalore in one year duration from 2020 to 2021. Two groups of children, forty in each group, aged between four to eight years, were included in the study. Groups were divided to perform single-visit and multi-visit endodontics with zinc-oxide eugenol and metapex as obturating material. The sample size of 40 were considered and allocated to respective group by concealment allocation. The conventional pulpectomy procedure was carried out. The post operative pain was assessed by using the pain scale through the telephonic conversation with the patient within 24 hours of treatment. Proportions were compared using Chi-square test of significance and the "p" value of less than 0.05 indicates statistical significance. The results showed, no statistically significant difference in teeth obturated with zinc oxide eugenol and metapex in both single-visit and multi-visit pulpectomy. The comparison of zinc oxide eugenol and metapex in single-visit group and multi-visit group had a 'p' value of 0.9233 and 0.4233 respectively. There were no differences between single and multi-visit treatment protocols with respect to the incidence of post operative pain. Single visit pulpectomy can be performed with added advantages with either zinc oxide eugenol or metapex.

Abstract
This research aims to understand better the application of Artificial Intelligence (AI) cases in the insurance industry, including healthcare companies. In particular, we want to expand the size and market penetration of AI in insurance markets to boost customer satisfaction in the insurance industry. The analytical model attempts to define the relationship between AI and its implementation in the insurance industry. Rigorous research to test the definition was carried out through a sample of international corporations and insurance firms. This work presents various practical findings that insurance companies consider quite useful when responding to dissatisfied customers and certain organizational concerns. This paper aims to identify the challenges and enablers that have evolved in the context of artificial intelligence adoption, specifically in the finance sector, and to analyze the impact of this disruptive technology on the organization’s financial performance and market capitalization. The findings indicate that, in addition to the various risks and challenges associated with artificial intelligence adoption, it is critical for all financial institutes or companies involved in financial tasks to adopt artificial intelligence to compete globally.

Abstract
Differentiating stem cells must coordinate their metabolism and fate trajectories. Here, we report that the catalytic activity of the glycolytic enzyme Enolase 1 (ENO1) is directly regulated by RNAs leading to metabolic rewiring in mouse embryonic stem cells (mESCs). We identify RNA ligands that specifically inhibit ENO1's enzymatic activity in vitro and diminish glycolysis in cultured human cells and mESCs. Pharmacological inhibition or RNAi-mediated depletion of the protein deacetylase SIRT2 increases ENO1's acetylation and enhances its RNA binding. Similarly, induction of mESC differentiation leads to increased ENO1 acetylation, enhanced RNA binding, and inhibition of glycolysis. Stem cells expressing mutant forms of ENO1 that escape or hyper-activate this regulation display impaired germ layer differentiation. Our findings uncover acetylation-driven riboregulation of ENO1 as a physiological mechanism of glycolytic control and of the regulation of stem cell differentiation. Riboregulation may represent a more widespread principle of biological control.

Abstract
Entacapone, a reversible catechol-o-methyl transferase inhibitor, is used to enhance the action of dopamine agonists by reducing their metabolism and the 'Wearing-off' effects associated with long-term use in the treatment of Parkinson's disease. It is used as an adjunct to levodopa/Carbidopa therapy. Due to limited dissolution and first-pass clearance, it suffers low and variable bioavailability issues. To overcome this problem, the present study aims to explore the potential of nanostructured lipid carriers (NLCs) for the delivery of Entacapone. The Quality by Design (QbD) approach was used for the systematic development of NLCs. The 23 full factorial designs were investigated using Design-Expert®11 software. The three independent variables namely content of total lipid (X1), surfactant (X2), and sonication time (X3) were optimized against two responses namely particle size and entrapment efficiency. The optimized NLCs were characterized for their size, surface morphology, entrapment efficiency, drug release, thermal and crystallographic studies. In-vivo pharmacokinetic studies in Entacapone-loaded NLCs showed an increase in t1/2, AUC0-∞, MRT compared to free drug. The reduction in elimination (Kel) depicts the prolonged action of Entacapone by loading in NLCs. The results displayed Entacapone-loaded NLCs have promising potential for oral delivery and enhanced therapeutic effect which otherwise was a major issue.

Abstract
This article provides comprehensive and collective facts about teneligliptin. Teneligliptin is a dipeptide peptidase-4 (DPP-4) inhibitor that belongs to the third generation, used in the management of type 2 diabetes. It inhibits human DPP-4 enzyme activity. This drug falls under class 3; it interacts with S1, S2, and S2E extensive sub-sites. Teneligliptin and its metabolites are mainly determined in the human plasma matrix by hyphenated chromatographic methods. These developed methods could be foreseen for their clinical applications. Moreover, the stress degradation studies of Teneligliptin under different stress conditions provide an insight into degradation pathways and help in the elucidation of the structure of the degradation products by liquid mass spectroscopy. These methods are also used for routine quality control analysis of teneligliptin in pharmaceutical dosage forms.

Abstract
Alalevonadifloxacin (ALA) is a novel antibacterial drug, recently launched in India to treat infections caused by Gram-positive bacteria. In present work, a chiral high-performance liquid chromatographic method was developed and validated for the quantification of a diastereomeric impurity (DI) in ALA. The separation was achieved on Pirkle type (R,R) Whelk-O1 chiral stationary phase, using ammonium formate buffer and acetonitrile in gradient fashion at a flow rate of 1.5 ml/min. The method was extensively validated for the quantification of DI in ALA. The detector response for DI was linear over the concentration range of 0.24-4.78 μg/ml. Limit of quantitation and limit of detection for DI were 0.24 and 0.07 μg/ml respectively. The mean recovery of the DI was 103.47 ± 5.14%. The impact of column temperature on the chiral separation was evaluated. The method was employed for controlling diastereomeric impurity in the batches of ALA used in preclinical studies.

Abstract
Nafithromycin is a next generation lactone ketolide antibiotic slated to enter phase III clinical development in India for the treatment of CABP as a shorter 800 mg-OD X3 day therapeutic regimen. Nafithromycin exhibits potent activity against MDR Streptococcus pneumoniae including erythromycin and telithromycin-resistant resistant strains. Older macrolides/ketolides are reported to be potent inhibitors of CYP3A4/5. To facilitate comparative assessment of drug-drug interaction potential, CYP inhibitory activities of nafithromycin was evaluated in comparison with clarithromycin, telithromycin, cethromycin and solithromycin. CYP inhibitory activities were assessed against key CYP isoforms (CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6 and CYP3A4/5) using human liver microsomes. Additionally, time-dependent inhibition (TDI), metabolism-based inhibition (MBI) and k inact /K I activities were also investigated for CYP3A4/5. Nafithromycin did not inhibit key CYP enzymes and was found to be a weak inhibitor of CYP3A4/5. Comparator antibiotics were found to be potent inhibitors with 2- to 50-fold leftward shifts in CYP3A4/5 IC50 values, while such shift was not noted for nafithromycin. k inact /K I ratio of nafithromycin was 3- to 153-fold lower than comparator drugs, further substantiating its lower affinity for CYP3A4/5. In sum, weaker inhibition and lower k inact /K I ratio for CYP3A4/5, points towards nafithromycin's lower propensities towards clinical drug-drug interactions as compared to other macrolides/ketolides antibiotics.

Abstract
Introduction: Rifabutin (RFB) is a lipophilic, semi-synthetic antibiotic given for the treatment of atypical mycobacterial infections along with drug susceptible tuberculosis infections. The major challenges in its usage include low oral bioavailability (~20%) mainly due to its low solubility and extensive first pass metabolism. Aim: The present study aims to explore the pharmacokinetics, biodistribution and toxicity of nanocarrier of RFB. Materials and Methods: An experimental animal study was carried out in Institute for Industrial Research and Toxicology, Ghaziabad, Uttar Pradesh, India. RFB nanocarriers were formulated by using solvent diffusion evaporation method with minor modifications and characterised for its physicochemical properties by using various techniques like Field Emission Scanning Electron Microscopy (FESEM), Dynamic Light Scattering (DLS) method, High-Performance Liquid Chromatography (HPLC), X-ray Diffractometry (XRD), in-vitro release study etc. Further nanocarriers were also studied for in-vivo analysis using pharmacokinetics, biodistribution and toxicity studies. GraphPad Prism Software (Version 5.02) was used for the statistical analysis. Results: Nanocarriers of RFB were developed and evaluated for its safety and efficacy. The results of evaluation of nanocarrier for physical and chemical attributes revealed that its particle size obtained was 305-325 nm with low Poly Dispersity Index (PDI) of 0.26-0.36 and the high drug encapsulation efficiency (62.45-70.15%). The nanocarrier formulation showed a sustained release pattern in Simulated Intestinal Fluid (SIF) upto 48 hours and in Physiological Buffer System (PBS) upto 7 days. The in-vivo study showed that the nano-lipoidal drug has significant higher Tmax and Cmax plasma value with higher t1/2(h) values in comparison to plain drug. Moreover, the slow elimination rate (Kel) resulted in significant (p<0.001) prolonged half-life (t1/2), which was many fold higher than the plain drug. No significant change was observed in haematological and liver enzyme profile of rats in plain drug and drug with nano-lipoidal carrier. Nanocarriers showed that there was an increase cell survival rate in MTT assay as compared to normal drug. Conclusion: By using nanotechnology based formulations, dose and dosing frequency of drug administration can be reduced. Thus, RFB drug can be administered in more efficacious manner reducing its toxic side effects, which ultimately improves patient compliance.

Abstract
AIM The purpose of our investigation is to evaluate the anti-arthritic potential of isolated rosmarinic acid from the rind of Punica granatum. METHOD Rosmarinic acid was isolated by bioactivity-guided isolation from butanolic fraction of Punica granatum and acute toxicity of rosmarinic acid was carried out. The experiment was conducted at doses of 25 and 50 mg/kg, in Freund's complete adjuvant (FCA)-induced arthritic rats. Various parameters, that is arthritic score, paw volume, thickness of paw, hematological, antioxidant and inflammatory parameters such as glutathione (GSH), superoxide dismutase (SOD), malonaldehyde (MDA) and tumor necrosis factor-α (TNF-α) were also estimated. RESULTS Rosmarinic acid significantly decreased the arthritic score, paw volume, joint diameter, white blood cell count and erythrocyte sedimentation rate. It also significantly increased body weight, hemoglobin and red blood cells. The significantly decreased levels of TNF-α were observed in treated groups as compared to arthritic control rats (P < 0.001). At the same time antioxidant parameters (like GSH and SOD) were increased significantly while levels of MDA were significantly decreased (P < 0.001). CONCLUSION The outcome of the present research concludes that rosmarinic acid showed significant anti-arthritic potential in FCA-induced arthritis in Wistar rats. This study represented the therapeutic role of rosmarinic acid from Punica granatum for the management of arthritis/rheumatoid arthritis/osteoarthritis and related inflammatory complications with negligible side effects which was still far from complete mitigation with available conventional medicines.

Abstract
A chiral liquid chromatographic method was developed and validated for the quantification of R-enantiomer impurity (RE) in WCK 3023 (S-enantiomer), a new drug substance. The separation was achieved on Chiralpak IA (amylose-based immobilized chiral stationary phase), using a mobile phase consisting of n-hexane-ethanol-trifluoroacetic acid (70:30:0.2, v/v/v) at a flow rate of 1.0 mL/min. The method was extensively validated for the quantification of RE in WCK 3023 and proved to be robust. For RE the detector response was linear over the concentration range of 0.11-5 μg/mL. The limit of quantitation and limit of detection for RE were 0.11 and 0.04 μg/mL respectively. Average recovery of the RE was in the range of 98.11-99.55%. The developed method was specific, sensitive, precise and accurate for quantitative determination of RE in WCK 3023. The impact of thermodynamic parameters on the chiral separation was evaluated. The method was employed for controlling the enantiomeric impurity in the lots of WCK 3023 used for pre-clinical studies. The method was successfully applied to evaluate the possible conversion of WCK 3023 to RE in rat serum samples during pre-clinical pharmacokinetic studies.

Abstract
This review refers to the all-inclusive details of Lorcaserin Hydrochloride on comprehensive information about the synthesis, analytical methods, pharmacodynamics, pharmacokinetics, drug interactions and adverse effects. Lorcaserin Hydrochloride is chemically (R)-8-Chloro-1-methyl-2,3,4,5- tetrahydro-1H-3-benzazepine hydrochloride. Lorcaserin HCl is a novel, synthetic, centrally-acting selective serotonin C (5-HT2c) receptor, l agonist, which results in increased satiety and decreased food consumption in patients. Headache, dizziness and nausea are the most common side effects associated with this drug. Lorcaserin HCl has two major metabolites, one conjugated with glucuronide called N-carbamoyl glucuronide which is excreted in urine and the second Lorcaserin N-sulfamate, which is circulated in the blood. Lorcaserin HCl is synthesized using four different schemes of which a six-step method that resulted in 92.3% yield with 99.8% of purity is employed for scale-up production. It is analyzed quantitatively in the plasma and brain tissue matrix of rats by Ultra Performance Liquid chromatographic (UPLC) method using MS-MS (Mass Spectrometric) detection.

According to world health organization and organisation for economic co-operation and development epidemiology reports, overweight and obesity are the fifth foremost causes of deaths globally. The increasing rate of obesity is becoming a mammoth problem which enormously affects an individual's quality of life. The conventional therapy of obesity mainly involves synthetic moieties and surgical procedures, which has many harmful side effects and chances of recurrence with severity. Hence, the Present review is a metanalysis of all the available data on the use of the plants with their biological source, active phytochemical constituents and a probable mechanism of action as natural anti-obesity agents. The metanalysis of data during the period of 2000-2018 was performed with the help of scientific data search engine National Center for Biotechnology Information (NCBI/PubMed). This data reveals the need and scope of further research in the development of new natural phytoconstituents for the management of obesity.

Abstract
Background: Grading of oral epithelial dysplasia (OED) by a pathologist is currently the key guide used for treatment planning of oral potentially malignant disorders (OPMDs). Conventional oral examination (COE) clinically detects OPMDs but may not predict their risk status to transform to cancer. Therefore, there is a need for a reliable test to predict OED in OPMDs. Aim: This study was conducted to evaluate COE, liquid based cytology (Cytopath) and DNA image cytometry (Ploidy) in predicting OED in OPMDs. Methods: A total of 179 patients from Malaysia, India and Indonesia underwent COE followed by brush biopsies and scalpel biopsies. Brush-biopsy samples were analyzed for cytopathology and DNA ploidy at Dental Faculty, University of Malaya. Histopathological findings of presence/absence of OED were used as the reference standard. Calculations for sensitivity (Sn), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV) and accuracy (A) were done for individual tools and in combinations. The Youden index (Sn+Sp-1) was used as a measure of overall performance. The relevant medical ethics committees of the different research locations approved the study. Results: For COE, the sensitivity (Sn) was high (100%) and the specificity (Sp) was low (5.9%), while both Cytopath and Ploidy showed a low sensitivity (Sn) (28.6% and 22.2%) and high specificity (Sp) (94.3% and 82.3%). All 3 tools individually have high negative predictive value (NPV) for predicting presence of OED (COE-100%, Cytopath-66.7%, Ploidy-78.5%). When combining outcomes from all 3 tools, the best performance indicated by Youden index (42.1) is which defines a positive case when both COE and Cytopath show abnormal. In general, using results from at least 2 tools had better Youden indices than using these tools individually. Conclusion: COE as a screening tool by virtue of its high Sn would be a suitable first level diagnostic test, while the Cytopath and the Ploidy individually with high Sp may be used as a second level test to predict presence of OED. Combining the COE with cytopathology would be the best combination for a high performance of the tools. Cytopathology (when performed by a trained cytologist) would allow for most of the false positives from the first level test to be correctly identified as true negative at the second level. Longitudinal data are needed to assess which of these may correctly identify the malignant potential of OPMDs.

Abstract
We show here that copper carbenes generated from diazo acetamides alkylate single RNAs, mRNAs, or pools of total transcriptome RNA, delivering exclusively alkylation at the O6 position in guanine (O6G). Although the reaction is effective with free copper some RNA fragmentation occurs, a problem we resolve by developing a novel water-stable copper N-heterocyclic carbene complex. Carboxymethyl adducts at O6G are known mutagenic lesions in DNA but their relevance in RNA biochemistry is unknown. As a case-in-point we re-examine an old controversy regarding whether O6G damage in RNA is susceptible to direct RNA repair.

Abstract
A precise and accurate liquid chromatography-tandem mass spectrometric (LC-MS/MS) bioanalytical method has been developed and validated for the simultaneous quantification of zidebactam (ZID) and cefepime (FEP) in dog plasma. Ceftazidime was used as an internal standard. Protein precipitation method was used as sample preparation approach. The calibration curve obtained was linear (r ≥ 0.99) over the concentration range 0.156-80 μg/mL for ZID and 0.312-160 μg/mL for FEP. The method was validated as per US Food and Drug Administration guidelines and the results met the acceptance criteria. A run time of 3.5 min for each sample made it possible to analyze the maximum number of samples per day. The proposed method was successfully applied for pharmacokinetic study in beagle dogs.

Abstract
A riverbank filtration (RBF) system was tested along the Kali River in rural part of the state of Karnataka in India. The polluted river and water from open wells served the local population as their principal irrigation water resource and some used it for drinking. Four RBF wells (up to 25 m deep) were installed. The mean hydraulic conductivity of the well field is 6.3 x 10(-3) cm/s and, based on Darcy's law, the water travel time from the river to the principal RBF well (MW3) is 45.2 days. A mixing model based on dissolved silica concentrations indicated that, depending on the distance from the river and closeness to irrigated rice fields, approximately 27 to 73% of the well water originated from groundwater. Stable isotopic data indicates that a fraction of the water was drawn in from the nearby rice fields that were irrigated with river water. Relative to preexisting drinking water sources (Kali River and an open well), RBF well water showed lower concentration of dissolved metals (60.1% zinc, 27.8% cadmium, 83.9% lead, 75.5% copper, 100% chromium). This study demonstrates that RBF technology can produce high-quality water from low-quality surface water sources in a rural, tropical setting typical for many emerging economies. Further, in parts of the world where flood irrigation is common, RBF well water may draw in infiltrated irrigation water, which possibly alters its geochemical composition. A combination of more than one mixing model, silica together with stable isotopes, was shown to be useful explaining the origin of the RBF water at this study site.

Abstract
The mushroom of commerce in the Western hemisphere, Agaricus bisporus, was administered orally to Swiss mice that were 6 weeks old at the start of the experiment The mushrooms were baked at 220-230 degrees C for 10 min. Subsequently, the mushrooms were fed to the animals for 3 days and were followed by a semisynthetic diet for 4 days each week, for life. The treatment induced tumors in the forestomach, glandular stomach, duodenum, and ovaries in the following incidences: 20, 12, 14 and 12% in females and 16, 20, 4 and 0% in males. In the tissues of the untreated controls, only an ovarian tumor was found in a female. Histopathologically, the neoplasms were classified as squamous cell papillomas and carcinomas of the forestomach, and adenomas and adenocarcinomas of the glandular stomach, duodenum, and ovaries. Since Agaricus bisporus is mainly eaten in baked form in the United States, the findings may carry useful implications.
