Plastidial thioredoxin-like proteins are essential for normal embryogenesis and seed development in Arabidopsis thaliana.

Thiol/disulfide-based redox regulation is a key mechanism for modulating protein functions in response to changes in cellular redox status. Two thioredoxin (Trx)-like proteins [atypical Cys His-rich Trx (ACHT) and Trx-like2 (TrxL2)] have been identified as crucial for oxidizing and deactivating several chloroplast enzymes during light-to-dark transitions; however, their roles remain to be fully understood. In this study, we investigated the functions of Trx-like proteins in seed development.

Methods: The association between the plasma concentration, after the first cycle of azacitidine and venetoclax therapy, and the efficacy and safety was evaluated in 33 patients with untreated or relapsed/refractory AML.

Results: Full dose of venetoclax was administered to all patients.

Overexpression of thioredoxin-like protein ACHT2 leads to negative feedback control of photosynthesis in Arabidopsis thaliana.

Thioredoxin (Trx) is a small redox mediator protein involved in the regulation of various chloroplast functions by modulating the redox state of Trx target proteins in ever-changing light environments. Using reducing equivalents produced by the photosynthetic electron transport chain, Trx reduces the disulfide bonds on target proteins and generally turns on their activities. While the details of the protein-reduction mechanism by Trx have been well investigated, the oxidation mechanism that counteracts it has long been unclear.

The serum levels of anti-β2GPI/HLA-DR antibody (normal < 73.3 U) were determined in 224 women with infertility.

Influence of Uterine Cavity Breach in Laparoscopic Myomectomy on the Risk of Obstetric Complications.

Objectives: Prepregnancy myomectomy is effective for the treatment of infertility or prevention of obstetric complications and is usually performed with laparoscopy. However, pregnancies following myomectomy have risks of obstetric complications, especially in cases with uterine cavity breaches, but the evidence remains unclear. We investigated how uterine cavity breach in laparoscopic myomectomy influenced the occurrence of obstetric complications.

Effect of Polyphenols on the Ice-Nucleation Activity of Ultrafine Bubbles.

Ultrafine bubbles (UFBs) in water provide a large amount of gas and a large gas-liquid interfacial area, and can release energy through their collapse. Such features may promote ice nucleation. Here, we examined the nucleation of ice in solutions containing polyphenols and UFBs.

Hysteroscopic resection with temporary balloon catheter occlusion of bilateral internal iliac arteries for managing retained products of conception after spontaneous abortion: Two cases report.

Retained products of conception (RPOC) is a condition in which trophoblastic tissue remains in the uterus after pregnancy, causing massive hemorrhage in some cases. Though RPOC is commonly treated by intrauterine curettage or hysteroscopic resection uterine artery embolization or hysterectomy may be performed in case of massive bleeding. We experienced two cases of RPOC after surgery for missed abortion that failed to respond to conservative treatment and required surgical treatment.

Reversal of neuroinflammation in novel GS model mice by single i.c.v. administration of CHO-derived rhCTSA precursor protein.

Galactosialidosis (GS) is a lysosomal cathepsin A (CTSA) deficiency. It associates with a simultaneous decrease of neuraminidase 1 (NEU1) activity and sialylglycan storage.
