Liver
It plays a crucial role in metabolism, detoxification, and the production of essential proteins and enzymes.
The liver is involved in the regulation of blood sugar levels, the synthesis of cholesterol and other lipids, and the breakdown of drugs and other toxic substances.
Disorders affecting the liver can lead to a range of health issues, including cirrhosis, hepatitis, and liver cancer.
Ongoing research aims to elucidate the complex mechanisms underlying liver function and develop effective treatments for liver-related conditions.
Optimiing liver research protocols using advanced AI-driven tools like PubCompare.ai can help researchers identify the most effective approahces and maximize the impact of their work.

We obtained data regarding cases outside Hubei province from the National Health Commission. Because of the high workload of clinicians, three outside experts from Guangzhou performed raw data extraction at Wuhan Jinyintan Hospital, where many of the patients with Covid-19 in Wuhan were being treated.
We extracted the recent exposure history, clinical symptoms or signs, and laboratory findings on admission from electronic medical records. Radiologic assessments included chest radiography or computed tomography (CT), and all laboratory testing was performed according to the clinical care needs of the patient. We determined the presence of a radiologic abnormality on the basis of the documentation or description in medical charts; if imaging scans were available, they were reviewed by attending physicians in respiratory medicine who extracted the data. Major disagreement between two reviewers was resolved by consultation with a third reviewer. Laboratory assessments consisted of a complete blood count, blood chemical analysis, coagulation testing, assessment of liver and renal function, and measures of electrolytes, C-reactive protein, procalcitonin, lactate dehydrogenase, and creatine kinase. We defined the degree of severity of Covid-19 (severe vs. nonsevere) at the time of admission using the American Thoracic Society guidelines for community-acquired pneumonia.15 (link)All medical records were copied and sent to the data-processing center in Guangzhou, under the coordination of the National Health Commission. A team of experienced respiratory clinicians reviewed and abstracted the data. Data were entered into a computerized database and cross-checked. If the core data were missing, requests for clarification were sent to the coordinators, who subsequently contacted the attending clinicians.

Clinicians can use several biochemical measurements to objectively assess patients' current or past alcohol use. Several more experimental markers hold promise for measuring acute alcohol consumption and relapse. These include certain alcohol byproducts, such as acetaldehyde, ethyl glucuronide (EtG), and fatty acid ethyl esters (FAEE), as well as two measures of sialic acid, a carbohydrate that appears to be altered in alcoholics (Peterson K, Alcohol Research and Health, 2005). Clinicians have had access to a group of biomarkers that indicate a person's alcohol intake. Several of these reflect the activity of certain liver enzymes: serum gamma-glutamyltransferase (GGT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and carbohydrate-deficient transferrin (CDT), a protein that has received much attention in recent years. Another marker, N-acetyl-β-hexosaminidase (beta-Hex), indicates that liver cells, as well as other cells, have been breaking down carbohydrates, which are found in great numbers in alcohol (Javors and Johnson 2003).
In some embodiments the disclosed device focuses on detecting markers associated with alcohol abuse from menstrual blood or cervicovaginal fluid.

Five groups including tucaresol, tucaresol plus PD-1 or PD-L1 antibody, tucaresol plus CTLA-4 antibody, CTLA-4 antibody plus PD-1 or PD-L1 antibody, and tucaresol plus plinabulin are tested to determine their effect in an animal xenograft model.
The combined treatment with tucaresol and the checkpoint inhibitor(s) is tested in comparison with the treatment with tucaresol alone, the treatment with checkpoint inhibitor alone, or combination of checkpoint inhibitors. The tests are performed using seven to ten-week old athymic (nu/nu) mice that were injected subcutaneously with human tumor cell lines (of either solid or liquid tumor origin, for example of breast, lung, colon, brain, liver, leukemia, myeloma, lymphoma, sarcoma, pancreatic or renal origin). Six to ten testing groups are prepared, and each group includes 10 mice.
Each treatment starts at tumor size between 40-150 mm3 and continues until Day 24-56, when the animals are necropsied. To determine the efficacy of each treatment, the following data are collected: mortality; the body weight of the mice assessed twice weekly both prior to treatments; the rate of tumor growth as determined by the tumor size measurement (twice every week); the tumor growth index; overall survival rate; the tumor weight at necropsy; and the time required to increase tumor size 10 fold.
Example 18
Frozen tissue sections of liver were cut at 10 μm and air dried to the slides. After fixation in 10% formalin for 5 min, the slides were briefly washed with running tap water for 10 min, followed by rinse with 60{circumflex over ( )} isopropanol. Subsequently, oil red O working solution (0.3% oil red O) was used for lipid staining for 15 min. Slides were again rinsed with 60% isopropanol and then nuclei were lightly stained with alum haematoxylin, followed by rinse with distilled water and mounted in glycerine jelly. After half an hour, pictures were taken under microscopy.

In this experiment, siRNAs or ASOs targeting a target mRNA will be conjugated to a GaINAc moiety and administered to mice (n=5/group), and compared to a control experiment where the mice are administered siRNAs or ASOs without GaINAc conjugation. Mice are sacrificed 2 days later, and livers are frozen, later homogenized, and tested for target mRNA and protein expression. The amount of target mRNA or protein expression in the livers of mice treated with the GaINAc-conjugated siRNAs or ASOs is normalized and compared to the amount of GFP mRNA or protein expression in the livers of mice treated with the siRNAs or ASOs that are not GaINAc-conjugated. This may allow for a determination of the liver targeting ability of the GaINAc moiety. Multiple GaINAc moieties may be conjugated to the siRNAs or ASOs and compared to see which GaINAc moiety results in optimal liver targeting. The GaINAc moieties included in this experiment may be those that exhibit the greatest degree of hepatocyte targeting. The GaINAc moieties to be tested in these experiments may a GaINAc moiety described herein.

CH25H was originally known to regulate cholesterol metabolism. However, when we compared the body weight, lipid deposition in liver and key enzymes involved in lipid metabolism, there was no significant change between WT and STAT1−/− mice (
