Aflatoxins in Wheat Grains: Detection and Detoxification through Chemical, Physical, and Biological Means.

Wheat (Triticum aestivum L.) is an essential food crop in terms of consumption as well as production. Aflatoxin exposure has a widespread public health impact in economically developing nations, so there is a need to establish preventive techniques for these high-risk populations. Pre-harvest and post-harvest practices are the two strategies used to control aflatoxin contamination, which include the use of genetically modified crops that show resistance against Aspergillus infection, the use of pesticides, changing the planting and harvesting time of crops, and physical, chemical, and biological methods. In this research, aflatoxin detection and quantification were performed in different wheat varieties to determine quantitative differences in comparison to the European Commission's limit of 4 ppb aflatoxins in wheat. TLC for qualitative and the ELISA kit method for quantitative analysis of aflatoxins were used. Out of 56 samples, 35 were found contaminated with aflatoxins, while the remaining 21 samples did not show any presence of aflatoxins. Out of the 35 contaminated samples, 20 samples showed aflatoxin contamination within the permissible limit, while the remaining 15 samples showed aflatoxin concentration beyond the permissible level, ranging from 0.49 to 20.56 ppb. After quantification, the nine highly contaminated wheat samples were detoxified using physical, chemical, and biological methods. The efficiency of these methods was assessed, and they showed a significant reduction in aflatoxins of 53-72%, 79-88%, and 80-88%, respectively. In conclusion, the difference in aflatoxin concentration in different wheat varieties could be due to genetic variations. Furthermore, biological treatment could be the method of choice for detoxification of aflatoxins in wheat as it greatly reduced the aflatoxin concentration with no harmful effect on the quality of the grains.

Coronary artery complications with left bundle branch area pacing: A review of literature.

Left bundle branch area pacing (LBBAP) is an emerging technique in cardiac resynchronization therapy that shows promise in improving ventricular synchrony and clinical outcomes in patients with heart failure. However, the potential risk of coronary artery complications with LBBAP necessitates careful attention and management. This literature review explores the mechanisms, acute coronary events, and clinical implications associated with coronary artery complications in LBBAP. The mechanism of coronary injury with LBBAP involves mechanical trauma, altered coronary blood flow dynamics, and endothelial damage. Acute coronary events such as myocardial ischemia, acute coronary syndromes, and coronary artery dissection can occur during or after LBBAP, leading to significant clinical implications including the need for prompt intervention and potential impact on long-term outcomes. To avoid coronary injury and acute coronary syndrome with LBBAP, specific care strategies are recommended. These include thorough pre-procedural evaluation, expert operator technique, optimization of hemodynamics and ventricular synchrony, close monitoring for ischemic events, collaboration with cardiology specialists, and long-term follow-up. The clinical implications of coronary artery complications with LBBAP necessitate careful patient selection, informed decision-making, and a multidisciplinary approach. Future directions in this field include advancements in procedural techniques, technological innovations, risk stratification strategies, enhanced imaging modalities, research on mechanisms and prevention, and collaboration among stakeholders. By implementing these strategies and focusing on future advancements, healthcare providers can minimize the risk of coronary artery complications with LBBAP and optimize patient outcomes in cardiac resynchronization therapy.

Primary intracranial alveolar soft part sarcoma in a 22 years old female: a rare case report with literature review.

Alveolar soft part sarcoma is a very rare malignant neoplasm of peripheral muscular, adipose or neural tissue. Its occurrence, as a primary intracranial tumour, is even rarer. To the best of our knowledge, only nine cases of primary intracranial alveolar soft part sarcoma exist in English scientific literature. We attempt to write a comprehensive review on this poorly understood intracranial malignancy, with no evident systemic lesions, such as in the case of our 22 years old patient. In addition to absent definitive proof of benefit of radiologic or chemotherapeutic management, we highlight the role of surgery as the primary treatment. Younger patients with this tumour may have a worse prognosis than elderly patients.

An outlook on the current challenges and opportunities in DNA data storage.

Silicon is the gold standard for information storage systems. The exponential generation of digital information will exhaust the global supply of refined silicon. Therefore, investing in alternative information storage materials such as DNA has gained momentum. DNA as a memory material possesses several advantages over silicon-based data storage, including higher storage capacity, data retention, and lower operational energy. Routine DNA data storage approaches encode data into chemically synthesized nucleotide sequences. The scalability of DNA data storage depends on factors such as the cost and the generation of hazardous waste during DNA synthesis, latency of writing and reading, and limited rewriting capacity. Here, we review the current status of DNA data storage encoding, writing, storing, retrieving and reading, and discuss the technology's challenges and opportunities.

Carbon monoxide poisoning with an atypical presentation on MRI: Case report and literature review.

Introduction: Acute carbon monoxide poisoning can present with altered mentation, loss of consciousness, and other symptoms. Accurate diagnosis is based on a detailed history, clinical examination, and laboratory evidence. MRI is also crucial in detecting hypoxic-ischemic encephalopathy due to CO poisoning and has established superiority over CT scans. We report an atypical MR imaging pattern seen in a patient post-CO exposure. Case presentation: We report a case of a 35-year-old South Asian man who presented to the emergency department with loss of consciousness for an undetermined time. GCS on arrival was 4/15. Detailed history, physical examination, and radiological investigations confirmed the diagnosis of carbon monoxide poisoning. He was treated with 100% oxygen. Conclusion: MRI should be included as a diagnostic workup for suspected CO poisoning patients to evaluate hypoxic-ischemic encephalopathy. This will not only aid in the correct diagnosis but will also help in guiding the correct management of the patients.

Clinical outcomes of fasting in patients with chronic heart failure with preserved ejection fraction: A prospective analysis.

Fasting is a part of many world religions and in Islam fasting is obligatory for every adult Muslim during the month of Ramadan. Islam has exempted sick people from fasting; however, many people still partake in this activity. We investigated how Islamic fasting affects patients with heart failure with preserved ejection fraction (HFpEF). We enrolled 938 patients (fasting n = 456; non-fasting = 482) in this prospective observational study. The fasting group showed a decrease in NYHA functional class III (23.36% vs. 17.77%; p-value < 0.05) and IV (3.76% vs. 2.19%; p-value < 0.05), and an increase in class I(35.57% vs. 43.64%; p-value < 0.05). symptoms. This is an important area for physicians to advise patients with HFpEF to fast in the month of Ramadan as it can have a favorable effect on their symptoms and quality of life.

The interplay between the immune system and SARS-CoV-2 in COVID-19 patients.

Millions of people across the globe have been affected by coronavirus disease 2019 (COVID-19), which began in Wuhan, China, and is caused by SARS-CoV-2. COVID-19 has a variety of clinical characteristics and triggers immune responses required for the elimination of the viral agent. Currently, no effective treatment options are available for targeting SARS-CoV-2 infection. Repurposing of drugs such as chloroquine, thalidomide, and leflunomide alongside convalescent plasma is being employed as a therapeutic strategy. Clinical studies have shown that both asymptomatic and symptomatic patients can have an extremely active immune response that is largely attributable to immune system modulations. This includes cytokine storm syndrome (CSS), which affects the adaptive immune system, leading to exhaustion of natural killer (NK) cells and thrombocytopenia in some cases. This review examines the interaction of SARS-CoV-2 with the host immune system and the potential for the development of appropriate immunotherapy for the treatment of COVID-19.

Microbiota in cancer development and treatment.

PURPOSE: Human microbiota comprises of a variety of organisms ranging from bacterial species to viruses, fungi, and protozoa which are present on the epidermal and mucosal barriers of the body. It plays a key role in health and survival of the host by regulation of the systemic functions. Its apparent functions in modulation of the host immune system, inducing carcinogenesis and regulation of the response to the cancer therapy through a variety of mechanisms such as bacterial dysbiosis, production of genotoxins, pathobionts, and disruption of the host metabolism are increasingly becoming evident. METHODS: Different electronic databases such as PubMed, Google Scholar, and Web of Science were searched for relevant literature which has been reviewed in this article. RESULTS: Characterization of the microbiome particularly gut microbiota, understanding of the host-microbiota interactions, and its potential for therapeutic exploitation are necessary for the development of novel anticancer therapeutic strategies with better efficacy and lowered off-target side effects. CONCLUSION: In this review, the role of microbiota is explained in carcinogenesis, mechanisms of microbiota-mediated carcinogenesis, and role of gut microbiota in modulation of cancer therapy.

ROS-modulated therapeutic approaches in cancer treatment.

PURPOSE: Reactive oxygen species (ROS) are produced in cancer cells as a result of increased metabolic rate, dysfunction of mitochondria, elevated cell signaling, expression of oncogenes and increased peroxisome activities. Certain level of ROS is required by cancer cells, above or below which lead to cytotoxicity in cancer cells. This biochemical aspect can be exploited to develop novel therapeutic agents to preferentially and selectively target cancer cells. METHODS: We searched various electronic databases including PubMed, Web of Science, and Google Scholar for peer-reviewed english-language articles. Selected articles ranging from research papers, clinical studies, and review articles on the ROS production in living systems, its role in cancer development and cancer treatment, and the role of microbiota in ROS-dependent cancer therapy were analyzed. RESULTS: This review highlights oxidative stress in tumors, underlying mechanisms of different relationships of ROS and cancer cells, different ROS-mediated therapeutic strategies and the emerging role of microbiota in cancer therapy. CONCLUSION: Cancer cells exhibit increased ROS stress and disturbed redox homeostasis which lead to ROS adaptations. ROS-dependent anticancer therapies including ROS scavenging anticancer therapy and ROS boosting anticancer therapy have shown promising results in vitro as well as in vivo. In addition, response to cancer therapy is modulated by the human microbiota which plays a critical role in systemic body functions.
