Background: Alloantibodies for the Rh blood group are the most immunogenic antibodies found in the Chinese population, typically causing acute or delayed hemolytic transfusion reactions and fetal and neonatal hemolytic diseases. Autoantibodies are generally considered nonspecific, and approximately 50% of warm antibodies are secondary to a variety of diseases, especially hematologic tumors. In this case report, a rare autoantibody that mimics anti-C and anti-e specificity was identified.

Background: Glycosylated hemoglobin (HbA1c) is a stable compound in human blood that covalently binds the N-terminal valine residue of the β-chain in hemoglobin A to the free aldehyde group of glucose. It can reflect the average blood glucose level of patients in the past 2 - 3 months. Therefore, the accuracy of HbA1c detection results is of great significance for the diagnosis and differential diagnosis of diabetes.

Background: In Saudi Arabia, cervical cancer, frequently caused by human papillomavirus (HPV) infection, is a common cancer. The usual procedures for screening and diagnosing cervical cancer include Pap smears and HPV tests, even though they have considerable drawbacks, particularly for older women (> 60 years) who have limited access to or compliance with these tests. Urinalysis is a simple, noninvasive test that has been suggested as an alternative procedure.

S100A8/A9 Promotes Dendritic Cell-Mediated Th17 Cell Response in Sjögren's Dry Eye Disease by Regulating the Acod1/STAT3 Pathway.

Invest Ophthalmol Vis Sci

January 2025

Tianjin Key Laboratory of Retinal Functions and Diseases, Tianjin Branch of National Clinical Research Center for Ocular Disease, Eye Institute and School of Optometry, Tianjin Medical University Eye Hospital, Tianjin, China.

Purpose: To investigate the role of S100A8/A9 in the pathogenesis of Sjögren's dry eye disease (SjDED) and explore its potential mechanism of action.

Methods: S100A8/A9 expression was determined by western blot and quantitative real-time polymerase chain reaction (qRT-PCR). Tear secretion, corneal fluorescein staining, and hematoxylin and eosin staining were used to evaluate the effect of paquinimod, a S100A8/A9 inhibitor, on dry eye disease in nonobese diabetic (NOD) mice.

Background: It is generally accepted that the greater palatine nerve and artery supply the palatal mucosa, gingiva, and glands, but not the bone or tooth adjacent to those tissues. When the bony palate is observed closely, multiple small foramina are seen on the palatal surface of the alveolar process. The authors hypothesized that the greater palatine nerve and artery might supply the maxillary teeth via the foramina on the palatal surface of the alveolar process and the superior alveolar nerve and artery.

Multi-Cancer Early Detection Tests: State of the Art and Implications for Radiologists.

Radiology

January 2025

From the Departments of Radiology and Population Health, New York University Langone Medical Center, New York, NY (S.K.K.); Division of Public Health Sciences, Fred Hutchinson Cancer Center, Seattle, Wash (R.G.); Department of Medicine, Vagelos College of Physicians and Surgeons, Columbia University, New York, NY (N.M., C.H.); Herbert Irving Comprehensive Cancer Center, New York, NY (C.H., E.B.E.); and Department of Health Policy and Management, Mailman School of Public Health, Columbia University, New York, NY (E.B.E.).

Multi-cancer early detection (MCED) tests are already being marketed as noninvasive, convenient opportunities to test for multiple cancer types with a single blood sample. The technology varies-involving detection of circulating tumor DNA, fragments of DNA, RNA, or proteins unique to each targeted cancer. The priorities and tradeoffs of reaching diagnostic resolution in the setting of possible false positives and negatives remain under active study.

Ergothioneine (ERG) is a natural sulfur-containing amino acid found in many organisms, including humans. It accumulates at high concentrations in red blood cells and is distributed to various organs, including the brain. ERG has numerous health benefits and antioxidant capabilities, and it has been linked to various human physiological processes, such as anti-inflammatory, neuroprotective, and anti-aging effects.

Variable surface antigen expression, virulence, and persistent infection by malaria parasites.

Microbiol Mol Biol Rev

January 2025

Department of Microbiology and Immunology, Weill Cornell Medical College, New York, New York, USA.

SUMMARYThe human malaria parasite is known for its ability to maintain lengthy infections that can extend for over a year. This property is derived from the parasite's capacity to continuously alter the antigens expressed on the surface of the infected red blood cell, thereby avoiding antibody recognition and immune destruction. The primary target of the immune system is an antigen called PfEMP1 that serves as a cell surface receptor and enables infected cells to adhere to the vascular endothelium and thus avoid filtration by the spleen.

In 2023, we published a case study involving a 10-year-old HIV-1-infected child with low-level viremia (LLV). We showed that this child patient achieved successful viral suppression by modifying the antiretroviral therapy (ART) regimen according to the HIV-1 DNA genotypic drug resistance testing. In this study, we aimed to address whether HIV-1 DNA genotypic drug resistance testing could direct successfully virological suppression in HIV-1-infected patients experiencing persistent LLV based on evidence from a cohort study.

The vascular endothelium and its endothelial glycocalyx contribute to the protection of the endothelial cells from exposure to high levels of sodium and help these structures maintain normal function by regulating vascular permeability due to its buffering effect. The endothelial glycocalyx has negative surface charges that bind sodium and limit sodium entry into cells and the interstitial space. High sodium levels can disrupt this barrier and allow the movement of sodium into cells and extravascular fluid.
