Background: Cerebral circulatory changes in preeclampsia are unclear. We studied the changes in intracranial blood flow volume using a new color Doppler ultrasonographic assessment in a preeclamptic woman with photophobia.
Case: A 39-year-old preeclamptic primigravida was admitted and delivered by cesarean at 36 weeks' gestation. She developed bilateral photophobia with blood pressure elevation at 2 days postpartum. Blood flow volume index [mean velocity x pid(2)/4] (d = luminal diameter at systolic phase) was established. The sum of blood flow volume indexes of the bilateral internal carotid arteries and vertebral arteries increased at the onset of photophobia and blood pressure elevation. The blood flow volume index increased above 120 mm Hg of mean arterial blood pressure.
Conclusion: These data represent the increased cerebral hemodynamic changes in preeclampsia with photophobia.

Background: Regulatory T-cells (Tregs) play a crucial role in maintaining immune homeostasis, but their dynamics are altered in a subset of people living with Human Immunodeficiency Virus (HIV) known as immunological non-responders (INRs). INRs fail to reconstitute CD4 T-cell counts despite viral suppression. This study aimed to examine Treg dysregulation in INRs, comparing them to immunological responders (IRs) and healthy controls (HCs).

Objective: This study compared the value of different systemic immune-inflammatory markers for evaluating coronary collateralization (CC) in patients with type 2 diabetes mellitus (T2DM) and chronic total occlusion (CTO).
Methods: Systemic immune-inflammation index (SII), systemic inflammation response index (SIRI) and pan-immune-inflammation value (PIV) were calculated at admission in 1409 T2DM patients with CTO. The degree of coronary collaterals was estimated using the Rentrop scoring system and categorized into poor (Rentrop score 0 or 1) or good (Rentrop score 2 or 3) CC.

Background: Immune checkpoint inhibitors play an important role in the treatment of solid tumors, but the currently used immune checkpoint inhibitors targeting programmed cell death-1 (PD-1), programmed cell death ligand-1 (PD-L1), and cytotoxic T-lymphocyte antigen-4 (CTLA-4) show limited clinical efficacy in many breast cancers. B7H3 has been widely reported as an immunosuppressive molecule, but its immunological function in breast cancer patients remains unclear.
Methods: We analyzed the expression of B7H3 in breast cancer samples using data from the Cancer Genome Atlas Program (TCGA) and the Gene Expression Omnibus (GEO) databases.

Background: Peste des petits ruminants (PPR) is an acute or subacute, highly contagious, and economically important, transboundary disease of small ruminants caused by Peste des petits ruminants virus (PPRV).
Objectives: The objective of this study was to determine the seroconversion rate in PPR vaccinated flock of sheep (Sekela district) and the seroprevalence of PPRV in unvaccinated flocks of sheep and goats (Yilmanadensa district).
Methods: A cross-sectional study was conducted from January to March 2022 in two selected districts of West Gojjam zone, Ethiopia.

Objective: To investigate serum TL1A levels and their correlation with Th17 cells, IL-17, and IL-21 in children with Graves' disease (GD).
Methods: Thirty-seven children (12 males and 25 females) aged 9-14 years with newly diagnosed and untreated GD were enrolled in this study. Serum TL1A, IL-17, and IL-21 levels were measured using enzyme-linked immunosorbent assay (ELISA).
