Objective: We aimed to analyze controlled ovarian stimulation using GnRH antagonist in association with hCG (dual triggering) versus hCG alone (conventional triggering) for final oocyte maturation triggering in a population of unselected Brazilian women.
Methods: This was a retrospective observational study of IVF medical records between January 2019 and March 2020. Data from 335 women with infertility were included for study. All patients were divided into hCG trigger (control group; n=178) and dual trigger (n=157).
Results: The number of total oocytes and the number of inseminated oocytes were all significantly higher with the dual trigger protocol compared to hCG-only trigger. However, there is no significant difference in patient age, type of infertility, number of in vitro matured oocytes, trigger day, endometrial thickness, AMH concentration, the number of follicles, the number of mature oocytes and the number of fertilized oocytes.
Conclusions: Using the dual trigger protocol improved the number of total oocytes retrieved and the number of inseminated oocytes.

In plants, cytoskeletal proteins assemble into dynamic polymers that play numerous roles in diverse fundamental cellular processes, including endocytosis, vesicle trafficking, and the spatial distribution of organelles and protein complexes. Plant elicitor peptides (Peps) are damage/danger-associated molecular patterns (DAMPs) that are perceived by the receptor-like kinases PEP RECEPTOR 1 (PEPR1) and PEPR2 to enhance innate immunity and inhibit root growth in Arabidopsis (Arabidopsis thaliana). To date, however, there is little evidence that the actin cytoskeleton of the host cell participates in DAMP-induced innate immunity.

Interaction with host cell receptors initiates internalization of Kaposi's sarcoma-associated herpesvirus (KSHV) particles. Fusion of viral and host cell membranes, which is followed by release of the viral capsid into the cytoplasm, is executed by the core fusion machinery composed of glycoproteins H (gH), L (gL), and B (gB), that is common to all herpesviruses. KSHV infection has been shown to be sensitive to inhibitors of vacuolar acidification, suggestive of low pH as a fusion trigger.

Background: Many different stress signaling pathways converge in a common response: slowdown or arrest cell cycle in the G1 phase. The G1/S transition (called Start in budding yeast) is a key checkpoint controlled by positive and negative regulators. Among them, Whi7 and Whi5 are transcriptional repressors of the G1/S transcriptional program, yeast functional homologs of the Retinoblastoma family proteins in mammalian cells.

Treatment of tumor brain metastases remains challenging due to the ineffectiveness of drugs in crossing the blood-brain barrier (BBB). Here, we proposed a potential strategy to target and modulate the meningeal lymphatic system for immunotherapy of breast cancer brain metastases (BCBM) through peripheral administration. CT/fluorescence dual-modality imaging demonstrated that the phospholipid nanoprobe (α-PLNPs) through intracisternal magna injection effectively labeled and long-range tracked the meningeal lymphatic pathway from meningeal lymphatic vessels (MLVs) to periphery drainage cervical lymph nodes (CLNs).

Background: Leukemia may form at any age, from newborns to the elderly, and accounts for considerable mortality worldwide.
Objectives: Nerolidol (NRD) is isolated from the aromatic florae oils and was found to have anticancer activities. However, the role of NRD in antiproliferative and apoptosis actions in acute lymphoblastic leukemia (ALL) is unclear.
