Traditional medicinal plants play an important role in primary health care worldwide. The phytochemical screening and activities of Geranium pusillum were investigated in this research. The dried plant leaves were extracted with ethanol, n-hexane, chloroform, dichloromethane, methanol, acetone, and aqueous solvents. These extracts were qualitatively analyzed, GC-MS, antimicrobial activities by using the disc diffusion method, antioxidant activity was determined by 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) radical scavenging, and cytotoxic activity was analyzed by the hemolytic activity of human red blood cells...

Irinotecan is a critical anticancer drug used to treat metastatic colorectal cancer and advanced pancreatic ductal adenocarcinoma by obstructing topoisomerase 1; however, it can cause minor-to-severe and life-threatening adverse effects. UDP glucuronosyltransferase family 1 member A1 ( UGT1A1 ) polymorphisms increase the risk of irinotecan-induced neutropenia and diarrhea. Hence, screening for UGT1A1 polymorphisms before irinotecan-based chemotherapy is recommended to minimize toxicity, whereas liposomes offer the potential to deliver irinotecan with fewer side effects in patients with pancreatic ductal adenocarcinoma...

Gold nanoclusters (AuNCs) are a class of novel luminescent nanomaterials that exhibit unique properties of ultra-small size, featuring strong anti-photo-bleaching ability, substantial Stokes shift, good biocompatibility, and low toxicity. Various biomolecules have been developed as templates or ligands to protect AuNCs with enhanced stability and luminescent properties for biomedical applications. In this review, the synthesis of AuNCs based on biomolecules including amino acids, peptides, proteins and DNA are summarized...

Arsenic (As) pollution in cultivated soils poses a significant risk to the sustainable growth of agriculture and jeopardizes food security. However, the mechanisms underlying how zinc (Zn) regulates the toxic effects induced by As in plants remain poorly understood. Hence, this study aimed to explore the potential of ZnO as an effective and environmentally friendly amendment to alleviate As toxicity in rice, thereby addressing the significant risk posed by As pollution in cultivated soils. Through a hydroponic experiment, the study assessed the mitigating effects of different ZnO dosages (Zn5 , 5 mg L-1 ; Zn15 , 15 mg L-1 ; Zn30 , 30 mg L-1 ) on rice seedlings exposed to varying levels of As stress (As0 , 0 µM L-1 ; As25 , 25 µM L-1 )...

INTRODUCTION: Incidental gallbladder carcinoma refers to a discovery of gallbladder cancer during or after cholecystectomy. Late port-site metastasis (PSM) following Laparoscopic cholecystectomy (LC) is rare with an incidence rate of 10.3%. PATIENT CONCERNS: We report a case of a 58-year-old man who presented with a painful abdominal wall mass for 6 weeks. He had a history of LC for symptomatic cholelithiasis, 8 years prior. DIAGNOSIS: Histopathological examination revealed a positive result for metastatic adenocarcinoma from the abdominal wall mass...

INTRODUCTION: Multiple pharmacological interventions have been studied for managing eosinophilic esophagitis (EoE). We performed a comprehensive systematic review and network meta-analysis of all available randomized controlled trials (RCT) to assess the efficacy and safety of these interventions in EoE in adults and children. METHODS: We performed a comprehensive review of Embase, PubMed, MEDLINE OVID, Cochrane CENTRAL, and Web of Science through May 10, 2023. We performed frequentist approach network meta-analysis using random effects model...

The complex relationship between probiotics and human health goes beyond their traditional function in gut health, generating considerable interest for their broad potential in disease treatment. This review explores the various functions of probiotics, highlighting their impact on the immune system, their benefits for gut and oral health, their effects on metabolic and neurological disorders, and their emerging potential in cancer therapy. We give significant importance to studying the effects of probiotics on the gut-brain axis, revealing new and non-invasive therapeutic approaches for complex neurological disorders...

Numerous studies have shown that oxidative stress plays an important role in peripheral artery disease (PAD). Prior reports suggested autonomic dysfunction in PAD. We hypothesized that responses of the autonomic nervous system and coronary tone would be impaired in patients with PAD during exposure to acute hyperoxia, an oxidative stressor. In 20 PAD patients and 16 healthy, sex and age-matched controls, beat-by-beat heart rate (HR, from ECG) and blood pressure (BP, with Finometer) were recorded for 10 minutes during room air breathing and 5 minutes of hyperoxia...

We performed whole-genome sequencing of four multidrug-resistant Enterococcus avium strains isolated from milk (4M1), feces (4F1 and 4F2), and farm soil (4S1) of mastitic dairy cows. The draft genomes of E. avium strains 4M1, 4F1, 4F2, and 4S1 were approximately 4.2 Mbp, with 39.1% GC content and 66.5× coverage.

With growing environmental concerns and a growing world population, there is an interest in developing cheap, efficient, and environmentally friendly substances that benefit humanity. Microbial surfactants are nontoxic, biodegradable bioproducts that provide sustainable solutions in agricultural applications due to their many benefits over their synthetic counterparts. Hence the crucial importance of scientific research to understand the effect of microbial surfactants on plant development. The present study aimed to assess the effect of rhamnolipid produced by Pseudomonas aeruginosa on seed germination of wheat ( Triticum aestivum ), barley ( Hordeum vulgare ), okra ( Abelmoschus esculentus ), onion ( Allium cepa ), and lettuce ( Lactuca sativa ) under laboratory conditions...

This article explores the application of deep learning techniques for sentiment analysis of patients' drug reviews. The main focus is to evaluate the effectiveness of bidirectional long-short-term memory (LSTM) and a hybrid model (bidirectional LSTM-CNN) for sentiment classification based on the entire review text, medical conditions, and rating scores. This study also investigates the impact of using GloVe word embeddings on the model's performance. Two different drug review datasets were used to train and test the models...

The global need for energy is increasing at a high rate and is expected to double or increase by 50%, according to some studies, in 30 years. As a result, it is essential to look into alternative methods of producing power. Solar photovoltaic (PV) power plants utilize the sun's clean energy, but they're not always dependable since they depend on weather patterns and requires vast amount of land. Space-based solar power (SBSP) has emerged as the potential solution to this issue. SBSP can provide 24/7 baseload carbon-free electricity with power density over 10 times greater than terrestrial alternatives while requiring far less land...
