Introduction: Pleomorphic Carcinoma (PC) is a subset of poorly differentiated non–small cell lung cancer that is diagnostically challenging because it is a rare malignancy of the lung. It shows varying dual-cell components; spindle or giant cells and epithelial cells.Method: We report a case of 68-year-old non-smoking female who presented with cough, fever, pain in the left side of chest & weight loss of recent onset and an abnormal shadow on her chest X-ray. Computed tomography of chest revealed a well defined heterogeneously enhancing cavitatory soft tissue lesion in the posterior basal segment of the left lower lobe with mediastinal lymphadenopathy.Results: Fine needle aspiration cytology& percutaneous lung biopsy confirmed poorly differentiated malignant tumor. Patient underwent a left lower lobectomy. A diagnosis of PC was confirmed after Immunohistochemistry (IHC). Mutation analysis revealed an EGFR exon 21 mutation within the tumor cells. The patient is on Gefitinib based chemotherapy and has remained disease-free for three years post-surgery.Conclusion: PC of the lung is a rare pathological entity. Definite diagnosis may only be made on a resected tumor along with the use of IHC. Surgical resection is the main modality of the treatment. Such rare cases should be documented to establish an optimal management plan and to provide a further insight to targeted therapy.

Introduction: Forensic psychology plays a critical role in the criminal justice system, bridging the gap between psychology and law enforcement. One of its most significant applications is in criminal profiling, which involves the analysis of crime scene evidence, behavioral patterns, and psychological indicators to construct a profile of potential offenders. This study explores the intersection of forensic psychology and criminal profiling, focusing on how psychological principles aid in understanding and predicting criminal behavior.Aim: The study aimed to evaluate the effectiveness and limitations of criminal profiling as a tool in criminal investigations, and to examine the methodologies that underpin profiling practices as a vital tool in the field of forensic sciences.Methodology: Qualitative content analysis of documented criminal cases from reputable journals were reviewed for this study. Related articles were searched for from Google Scholar and Research Gate using the Keywords. A selection of high-profile cases where profiling significantly contributed to suspect identification were analyzed to assess the practical utility of psychological profiling.Results: The results indicate that while criminal profiling is not a standalone solution, it offers valuable insights when integrated with traditional investigative techniques. Psychological constructs such as personality disorders, cognitive distortions, and behavioral consistency were found to be instrumental in building accurate profiles. However, the findings also highlight challenges including subjectivity, bias, and the risk of stereotyping, potentially compromising investigative objectivity.Conclusion: Forensic psychology, through the application of criminal profiling, provides a powerful adjunct to investigative procedures. When used responsibly and in conjunction with empirical data and forensic evidence, profiling can enhance the efficiency and direction of criminal investigations. Continued research and standardization of profiling methodologies are essential to maximize its reliability and effectiveness in modern forensic practice. This study contributes to a deeper understanding of the practical roles and limitations of forensic psychology’s role in the pursuit of justice.

Background: Monotherapy for liver dysfunction in diabetes is less effective. This study investigated the effect of combined linagliptin and metformin therapy on liver function in diabetic rats. Methods and materials: Sixty-four mature male (200-300 g) Wistar rats were used. Streptozotocin (35 mg/kgb.wt) was repeatedly injected intraperitoneally to induce diabetes. The rats were grouped into eight groups (n = 8). Group I: control; Group II: control + 10 mg/kgb.wt linagliptin; Group III: control + 200 mg/kgb.wt metformin; Group IV; control + 10 mg/kgb.wt linagliptin + 200 mg/kgb.wt metformin; Group V: diabetic; Group VI: diabetic + 10 mg/kgb.wt linagliptin; Group VII: diabetic + 200 mg/kgb.wt metformin; Group VIII: diabetic + 10 mg/kgb.wt linagliptin + 200 mg/kgb.wt metformin. The animals were sacrificed on the last day of the experiment, blood and liver samples were collected for biochemical assay. Results: Insulin, blood glucose, glycated hemoglobin, total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-cholesterol), liver function biomarkers, liver glucose metabolic enzymes, malondialdehyde and inflammatory markers increased (p < 0.05) significantly. High-density lipoprotein-cholesterol (HDL-cholesterol), liver antioxidant, glycogen, and glycogen synthase were reduced significantly in diabetic rats. Linagliptin and metformin administration single and combined reduced the insulin, blood glucose, glycated hemoglobin, total cholesterol, triglycerides, LDL-cholesterol, liver function biomarkers, liver glucose metabolic enzymes, malondialdehyde, and inflammatory markers, and increased the HDL-cholesterol, liver antioxidant, glycogen and glycogen synthase in diabetic rats.Conclusion: Linagliptin monotherapy alone efficiently controls hyperglycemia and remarkably improves liver functions. Combining linagliptin and metformin could be used as safe and effective therapy for liver dysfunction progression in diabetes.

A specialized installation has been developed for microscopic study of the Reactive Oxygen Species (ROS) formation during microwave irradiation of biological samples with automated control / mechanized tube and real-time data acquisition. The above installation can be used in biomedical practice for: standardization or certification of the microwave sources; testing of the potential antioxidants that protect tissues from ROS-induced effects; testing fluorescent sensors for ROS; analysis of ROS localization and distribution in various tissues in order to establish specific pharmaco-physiotherapeutic and toxicological localizations of ROS in different topographic-anatomical zones. The paper pays special attention to the singlet oxygen produced by the samples upon microwave treatment, as a physiologically active and highly reactive agent.

I wish to draw attention to the rising influence of short video content on social media and its potential negative impacts on adult health, particularly its contribution to conditions such as hypertension.

The role of free radicals and antioxidants is often underestimated despite their involvement in key metabolic processes, although they participate in many important metabolic processes in the life of humans, animals and plants. Their quantity and quality differ from each other, which is not respected. Each cell is attacked approximately 10,000 times by free radicals. Oxidative stress is the cause of many problems, especially in viral diseases. Monitoring of redox potentials in body fluids is usually not carried out. Viral replication is influenced by oxidative energy, derived from either host metabolism or free radical activity, which is supplied by oxidation by free radicals or the host. Nucleic acid mutations due to the effect of free radicals can be the cause of carcinomas, and possible defense against mutations could help eradicate dangerous viruses. The importance of malondialdehyde and antibodies against it is discussed. Eliminating free radicals, reducing lipoperoxidation, and protecting against environmental oxidative stress are important factors for human health.Study objective: To highlight the importance of free radicals, antioxidants and redox potentials for patient diagnosis and therapy.Methods: This study synthesizes findings from multiple published sources, including our own research.Results: Findings highlight the role of free radicals in oxidative stress, DNA damage, and viral replication, with redox potential (ORP) and Malondialdehyde (MDA) identified as key diagnostic markers.Conclusion: Monitoring oxidative balance and targeting free radical activity are essential for preventing cellular damage and improving clinical outcomes in oxidative stress-related diseases.

Hereditary Hemochromatosis (HH) is an inherited recessive autosomal disorder characterized by the accumulation of excess iron. When iron-binding proteins become saturated, concentrations of free or Non-transferrin-bound iron (NTBI) rise, a condition thought to be responsible for the adverse effects associated with HH. To investigate whether disturbing iron homeostasis plays a role in free radical injury in HH, protein carbonyls were found to be 1-7 times higher in patients with HH than in controls, with the greatest increases observed in untreated HH patients with high ferritin and > 90% transferrin saturation with iron. An unpaired t-test revealed a p value of 0.0278 (p < 0.05), which is considered statistically significant.In vitro oxidation of transferrin standards with hydrogen peroxide and excess iron, followed by immobilized trypsin digestion (Poroszyme), high-resolution LC-MS/MS analysis (Q-TOF Ultima, Waters), and MS/MS data processing (PEAKS, Bioinformatics Solution), identified several tryptic peptides containing oxidized Methionine (Met), Tryptophan (Trp), and Histidine (His) residues. Using the same methodology, oxidized residues were subsequently detected in transferrin isolated from plasma samples of patients severely affected by HH. Comparison of MS/MS spectra of in vitro oxidized samples with the most fragment ion peaks in common with oxidized peptide MS/MS spectra from patient samples revealed a strong correlation between the two. These data show that elevated NTBI may be involved in the oxidative modification of transferrin and that such modifications may play a significant role in the pathophysiology of HH.

In this work we are concerned with identifying visible evidence that can only be observed with the naked eye and is required for experiments by forensic scientists. The search details include many visible physical properties that could be used to explain many unknowns in the crime scene, which means critical truths for different cases. The details include appearance phenomena such as color, odor, shape, size, material type, and inferred properties based on physical appearance. The properties discussed in this work can be further analyzed using specific portable apparatuses that could give very important information about the structure and nature of the properties of evidence in a crime scene. We also deal in this work with general expertise, which forensic scientists should understand and could treat to make the process of identification and characterization in crime scenes be done more systematically in a short time.
