Anti-CTLA-4 m2a Antibody Exacerbates Cardiac Injury in Experimental Autoimmune Myocarditis Mice By Promoting Ccl5-Neutrophil Infiltration.

The risk for suffering immune checkpoint inhibitors (ICIs)-associated myocarditis increases in patients with pre-existing conditions and the mechanisms remain to be clarified. Spatial transcriptomics, single-cell RNA sequencing, and flow cytometry are used to decipher how anti-cytotoxic T lymphocyte antigen-4 m2a antibody (anti-CTLA-4 m2a antibody) aggravated cardiac injury in experimental autoimmune myocarditis (EAM) mice. It is found that anti-CTLA-4 m2a antibody increases cardiac fibroblast-derived C-X-C motif chemokine ligand 1 (Cxcl1), which promots neutrophil infiltration to the myocarditic zones (MZs) of EAM mice via enhanced Cxcl1-Cxcr2 chemotaxis.

[The Blood Group Serology Combined Irregular Antibody Prenatal Screening Strategies for RhDPregnant Women in Xiamen].

Objective: To investigate the distribution of Rh phenotype, irregular antibodies screenting and postpartum follow-up of RhD pregnant women in Xiamen.

Methods: The samples of 313 RhD pregnant women from June 2018 to May 2020 were collected. Rh serotype phenotypes were identified by tube physiological saline method, irregular antibodies were screened and confirmed by DiaMed Low ion indirect anti-human gel card.

Perceptions of Oncology Nurses Regarding Fertility Preservation and Providing Oncofertility Services for Men of Childbearing Age with Cancer.

This study investigated the knowledge, thoughts, and attitudes of oncology nurses in China regarding fertility preservation for male cancer patients of childbearing age, and for offering counseling or oncofertility services for the men in their care. Data was collected from 18 oncology nurses in Southwest China through voluntary self-report and in-depth interviews. The qualitative interview data were analyzed using a descriptive phenomenology method based on the lived experience of the nurses.

The Educational Program for Healthcare Providers Regarding Fertility Preservation for Cancer Patients: a Systematic Review.

The emerging discipline of oncofertility advocates for the timely provision of fertility preservation (FP) to all cancer patients of childbearing age by healthcare providers. A lack of practice due to limited FP-related knowledge was found among healthcare providers. A systematic review was undertaken on the educational programs on FP for healthcare providers.

A New Triterpenoid from the Aerial Parts of Agrimonia pilosa.

(1S,3R,17R,18R,19R,20R,22R)-1,3,19,22-tetrahydroxy-28-norurs-12-en-2-one (1), along with 5 known triterpenoids (2-6), were isolated from the aerial parts of Agrimonia pilosa Ledeb. Their structures were established based on extensive spectroscopic and MS analysis. The absolute configuration of compound 1 was deduced by circular dichroism (CD).

Hypolipidemic effect of gypenosides in experimentally induced hypercholesterolemic rats.

Background: To investigate the anti-hyperlipidemic effect of gynosaponins (GPs) in hyperlipidemic rats induced by high lipid diet.

Methods: Animal model of hyperlipidemia was established by high-fat and high-cholesterol diet. Rats were randomly divided into 6 groups, except the normal and model groups, rats in GPs groups were daily administered intragastrically with GPs (50, 100, and 200 mg/kg), and rats in simvastatin group were daily administered intragastrically with simvastatin (10 mg/kg).

(S)-(-)-5,5'-Bis(diphenyl-phosphino)-4,4'-bi-1,3-benzodioxole.

In the chiral title compound, C(38)H(28)O(4)P(2), the intra-molecular P⋯P separation is 3.671 (2) Å and the dihedral angle between the two benzene rings in the biphenyl unit is 77.9 (2)°.

3,5-Dihydr-oxy-N'-(2-hydroxy-benzyl-idene)benzohydrazide monohydrate.

The title potential anti-bacterial compound, C(14)H(12)N(2)O(4)·H(2)O, is a Schiff base which has an intra-molecular O-H⋯N hydrogen bond and crystallizes with one uncoordinated water mol-ecule, which links three symmetry-related mol-ecules through two O-H⋯O and one N-H⋯O hydrogen bond. In the crystal structure, further inter-molecular O-H⋯O hydrogen bonds link symmetry-related mol-ecules, forming layers parallel to the bc plane.
