In the fruit processing industry, peel is one of the main by-products. Non-edible portions of fruit are likewise seen as waste and are frequently thrown out into the environment. Nowadays, one of the main sources used by the pharmaceutical sector to isolate and extract secondary metabolites is fruit peels. Many applications known for lime peel, especially for antibacterial. This study focuses on the isolation, chemical composition characterization, and antibacterial activity on skin pathogenic bacteria of lime peel essential oil (LPEO). LPEO were isolated using steam distillation and characterized by GC/MS. A total of 24 components were identified. The major constituents of the LPEO were d-limonene (40.24%), β-terpinene (15.68%), sabinene (13.15%), citral (3.41%), α-Terpineol (3.40%), and terpinene-4-ol (2.94%). The antibacterial activity was determined using the Kirby-Baurer method against several bacteria that can cause skin infections. The antibacterial activity of LPEO against Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis dan Propionicbacterium acne is confirmed. LPEO showed varied levels of antibacteria activity against the gram positive and gram negative bacteria. Zone of inhibition (ZOI) in millimetres was used to measure the antibacterial activity, and amoxicillin was used as a control.  

Stress and burnout among healthcare workers represent a global crisis with significant implications for psychological and physical health, job performance, and interpersonal skills. These conditions are linked to anxiety, depression, suicidal ideation, substance use, poor quality of life, digestive disorders, and cardiovascular diseases. Burnout is characterized by emotional fatigue, depersonalization, and reduced personal accomplishment, often caused by chronic workplace stress. Factors such as demographics, fatigue, and resilience influence its development and severity. Traditional stress management interventions, such as counselling and leave, often prove insufficient in addressing these challenges. Recent advancements in Artificial Intelligence (AI) provide innovative tools for stress and burnout management, including mobile applications offering mindfulness, meditation, and self-care resources. AI systems like IBM Watson and Google DeepMind are being tested to enhance accessibility and effectiveness in stress management. Additionally, Stress Inoculation Training (SIT), involving methods such as meditation, yoga, cognitive-behavioural therapy, and biofeedback, has been recognized as a proactive approach to mitigating stress. This review explores the factors contributing to stress and burnout in healthcare workers and evaluates interventions aimed at improving well-being and productivity, emphasizing the potential of AI and SIT in preventing and managing these conditions.

Coumarin, a key bioactive compound in cinnamon, is known for its anticoagulant, antibiotic, and anti-carcinogenic properties. This study investigates the potential of cinnamon (Cinnamomum burmanni) extract as a natural anticoagulant using both the Lee-White method, for visual observation of clotting time, and blood smear analysis for microscopic evaluation. The research aims to assess the effectiveness of the extract in preventing blood coagulation compared to untreated blood samples. Results demonstrated that blood without any anticoagulant clotted within an average time of 5 minutes and 33 seconds. In contrast, blood treated with cinnamon extract did not exhibit coagulation, indicating a significant anticoagulant effect. Microscopic examination further supported these findings, as the blood cells in the treated samples appeared separated, with no visible aggregation or linkage between the cells. These findings suggest that cinnamon extract has strong potential as a natural anticoagulant, offering a safer and more accessible alternative to synthetic anticoagulants. Further research could explore its applications in medical treatments, particularly in conditions requiring blood thinning or clot prevention. This study highlights the potential of cinnamon as a valuable bioactive agent in the field of biomedical science, especially for anticoagulation therapies.
