Abstract

Blood transfusions are an important part of medicine for patient recovery. Therefore, the transfused blood must be free from viruses, bacteria, and even parasites that can be transmitted through blood transfusions. Human Immunodeficiency Virus (HIV/AIDS), Hepatitis C, Hepatitis B, and Syphilis are among the illnesses that can be transferred through blood transfusions. This research aims to determine screening parameters for transfusion-transmitted infection using the rapid diagnostic test method. This type of research is experimental with a cross-sectional design. The samples used were ten blood samples, taken intravenously and then centrifuged at a speed of 1300 rpm for 4 minutes. After that, screening is carried out with a rapid diagnostic test. The screening results of the ten blood samples examined were valid and negative or non-reactive for HIV/AIDS, Hepatitis C, Hepatitis B, and Syphilis. These results indicate that the blood samples tested can be categorized as blood samples that passed the screening test or the blood examination test for four parameters of transfusion-transmitted infection.

Abstract

The epidermal growth factor receptor (EGFR) is a crucial target in the treatment of non-small cell lung cancer (NSCLC) due to its significant role in tumor cell proliferation and survival. This study investigates the potential of marine-derived compounds from soft coral (Rhytisma sp.) as EGFR inhibitors through molecular docking and pharmacokinetic predictions. Eight compounds identified via GC-MS were docked against the EGFR tyrosine kinase domain (PDB ID: 2ITY) using AutoDock Vina, with Gefitinib serving as the reference drug. The top-performing compounds exhibited binding affinities ranging from –7.0 to –7.4 kcal/mol, closely aligning with Gefitinib's affinity of –7.6 kcal/mol. Notably, 4,12,12-trimethyl-9-methylidene-5-oxatricyclo[8.2.0.0⁴,⁶]dodecane demonstrated the strongest interactions, involving critical residues such as MET793 and LYS745. Pharmacokinetic profiling conducted with SwissADME and pkCSM confirmed favorable drug-likeness and high absorption potential. Toxicity analysis using ProTox-3.0 indicated low toxicity (Class IV) and no predicted hepatotoxicity, carcinogenicity, or mutagenicity. These findings suggest that phytocompounds derived from Rhytisma sp., particularly terpenoid-based structures, present a promising scaffold for the development of EGFR-targeted anticancer drugs.

Abstract

Air sterilization is an essential effort to maintain air quality in educational laboratory settings. Ultraviolet (UV) light, particularly UV-C, is known to be effective at reducing of airborne microorganisms. This study aimed to describe the effect of UV light exposure on airborne bacterial growth in the Transfusion Transmitted Infections (TTI) Laboratory and the donor selection at Guna Bangsa College of Health Sciences, Yogyakarta. This research employed a descriptive observational method with a cross-sectional design. Air sampling was conducted after UV exposure using the settle plate method on Nutrient Agar (NA) media for 30 minutes, placed at several points within the laboratory, and incubated at 37°C for 24 hours. The results showed that the TTI’s Laboratory had 3 CFU/m³ and the Donor Screening Room had 2 CFU/m3. These results remain well below the maximum allowable airborne bacterial colony count set by the Indonesian Ministry of Health Regulation No. 70 of 2016, which limits it to at 500 CFU/m³. This indicates that the air quality in both laboratories meets the microbiological cleanliness standard, although the UV disinfection was not fully effective.
