Activity of Lipoxygenase and Partial Purification of Its Isoenzymes in Patients with Viral Hepatitis B
Bibliographic record
Abstract
This work aimed to estimate lipoxygenase activity and purify its isoenzymes in humans, particularly in those with Hepatitis B Virus, thereby making variations in its normal levels a diagnostic marker for the disease.Hepatitis B is an infectious disease caused by the Hepatitis B Virus (HBV), leading to both acute and chronic inflammations.The current study was conducted to evaluate the activity of lipoxygenase (LOX), purify and separate its isomers partially.The study took place in Kirkuk city, Iraq from the first of January, 2021, to the 30 th of March, 2021, involving a cohort of 40 patients infected with viral Hepatitis B. Their ages ranged between 20 and 70 years, with the majority seeking care at the Gastrointestinal Tract Center (GIT) in Kirkuk's Azadi Teaching Hospital and Kirkuk General Hospital.Estimation of Lipoxygenase (LOX) enzyme activity, protein concentration, and purifying the enzyme were performed.The results indicated a significant elevation in the lipoxygenase activity in patients afflicted with viral hepatitis, with a probability of P ≤ 0.001 compared to the control group which serves as a strong indicator of hepatitis infection.The enzyme was purified using ammonium sulfate, achieving a 30% saturation.Excess salts were eliminated through membrane filtration.Further purification phases were completed utilizing gel filtration chromatography with a Sephadex G.100 column, yielding a single peak.The enzyme purification degree was determined to be 0.57554 times, with an enzyme yield of 26.10526%.Subsequently, isomers of the lipoxygenase were separated through ion exchange chromatography using DEAE-Cellulose.Three lipoxygenase LOX isomers, namely LOX1, LOX2, and LOX3, were obtained with varying degrees of purity, measured at (0.731330935), (0.679565947), and (0.707230216), respectively.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
