    Abstract Viruses of the phylum Nucleocytoviricota are ubiquitous in ocean waters and play important roles in shaping the dynamics of marine ecosystems. In this study, we leveraged the bioGEOTRACES metagenomic dataset collected across the Atlantic and Pacific Oceans to investigate the biogeography of these viruses in marine environments. We identified 330 viral genomes, including 212 in the order Imitervirales and 54 in the order Algavirales. We found that most viruses appeared to be prevalent in shallow waters (<150 m), and that viruses of the Mesomimiviridae (Imitervirales) and Prasinoviridae (Algavirales) are by far the most abundant and diverse groups in our survey. Five mesomimiviruses and one prasinovirus are particularly widespread in oligotrophic waters; annotation of these genomes revealed common stress response systems, photosynthesis-associated genes, and oxidative stress modulation genes that may be key to their broad distribution in the pelagic ocean. We identified a latitudinal pattern in viral diversity in one cruise that traversed the North and South Atlantic Ocean, with viral diversity peaking at high latitudes of the northern hemisphere. Community analyses revealed three distinct Nucleocytoviricota communities across latitudes, categorized by latitudinal distance towards the equator. Our results contribute to the understanding of the biogeography of these viruses in marine systems.

    Abstract Introduction: This study aimed to investigate differences in mater-nal and perinatal outcomes between dichorionic-diamniotic (DCDA) twin pregnancies between those conceived spontaneously and those conceived through in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI).
    Methods: This study was a single-center, retrospective cohort study. All women with DCDA twin pregnancies were considered for inclusion. Monochorionic twins and higher-order multiple pre-gnancies were excluded. All data related to maternal and perinatal outcomes were extracted from the hospital database and compared between spontaneously conceived DCDA twin pregnancies and those conceived by IVF/ICSI. Multivariable logistic regression was used to adjust for confounders to determine factors associated with maternal and perinatal outcomes.
    Results: Of 739 identified DCDA twin pregnancies, 483 (65.4%) were conceived through IVF/ICSI treatment (IVF/ICSI group), and 256 (34.6%) were spontaneously conceived (SC group). Women in the IVF/ICSI group were older and had fewer previous live births than women in the SC group. The women in the IVF/ICSI group had significantly higher risks of preeclampsia (adjusted odds ratio [aOR]: 2.50; 95% confidence interval [CI]: 1.12-5.55), cesarean delivery (aOR: 2.0; 95% CI: 1.27-3.17), an postpartum hemorrhage following cesarean section (aOR: 3.15; 95% CI: 1.53-6.45). The DCDA twins in the IVF/ICSI group were delivered at an earlier gestational age (36.2 vs. 36.7 weeks, p < 0.001), had slightly lower mean birth weights (2298 vs. 2367 g, p = 0.005), and required more respiratory support (aOR: 0.69; 95% Cl: 0.48-0.98) than those in the SC group.
    Conclusions: Our study demonstrated that women with DCDA twin pregnancies conceived through IVF/ICSI experienced more complications than those with SC DCDA twin pregnancies. Newborns in the IVF/ICSI group had a slightly lower mean birth weight and required respiratory support more frequently, but no other significant differences in perinatal outcomes or perinatal mortality were observed between the two groups.

    Abstract Chemical adsorption of non-metal atoms may lead to the emergence of novel features in two-dimensional (2D) materials. In this work, the electronic and magnetic properties of graphene-like XC (X = Si and Ge) monolayers with adsorbed H, O, and F atoms are investigated using spin-polarized first-principles calculations. Deeply negative adsorption energies suggest strong chemical adsorption on XC monolayers. Despite the non-magnetic nature of both host monolayer and adatom, SiC is significantly magnetized by H adsorption inducing the magnetic semiconductor nature. Similar features are observed in GeC monolayers upon adsorbing H and F atoms. In all cases, an integer total magnetic moment of 1

    Abstract Otostigmus consonensis sp. nov. was described from Vietnam, and O. sulcipes Verhoeff, 1937 was recorded for the first time in this country. The new species can be recognized by having 18 antennomeres including 2.32.5 glabrous basal ones, three coxosternal teeth, tergites 520 with complete paramedia sutures, sternites with incomplete paramedian sutures, and the ultimate leg with 1115 prefemoral spines. The fragment of the COI gene was extracted for each species; thus, a new species and a record of O. sulcipes were supported by the COI genetic distances and the corresponding phylogenetic analysis.

    Abstract Using post-mining areas for planting energy crops has emerged as a promising and sustainable reclamation solution due to its potential contributions to environmental protection, land restoration, and especially energy security. However, to ensure the sustainability of this reclamation solution, its environmental performance needs to be thoroughly assessed case by case. Located in Ha Thuong Commune, Dai Tu District, Thai Nguyen Province in northern Vietnam, Nui Phao is the world’s largest tungsten mine. To restore post-mining sites at Nui Phao, cassava planting for ethanol production was one of the proposed measures. To support the decision-making, this study employs life cycle assessment to thoroughly evaluate the environmental performance and potential environmental benefits/costs of cassava-based reclamation system in terms of resource consumption and green house gas (GHG) emission. The results show that cassava-based reclamation might bring significant environmental benefits in terms of fossil fuel saving and GHGs reduction (i.e., reduce 50% fossil fuel consumption and 36% GHGs emission); however, it does not bring any benefit in terms of water and land resource consumption. Moreover, the results define cassava cultivation as the “hot spot” of the system, where innovations to enhance the yield and reduce water and fertilizer consumption are required to improve the environmental performance of the cassava-based reclamation system.

    Abstract Objectives: To monitor changes in serum anti-Mullerian hormone (AMH) levels of the patients with gestational trophoblastic neoplasia (GTN) who have undergone uterine preservation during treatment with a Methotrexate (MTX) regimen and associations with AMH variations.
    Methods: This observational prospective cohort study included 35 patients with low-risk GTN with uterine preservation during single-agent MTX chemotherapy at Hanoi Obstetrics and Gynecology Hospital from August 2021 to August 2022. Serum AMH levels were measured before initiation of chemotherapy and after the 1st, 2nd, and 3rd chemotherapy cycles. AMH evolution and its associations with some factors were analyzed.
    Results: The median basal AMH level before chemotherapy was 2.87 ng/mL (0.96 - 7.9 ng/mL) and negatively correlated with age. The serum AMH levels decreased significantly after each chemotherapy cycle (2.87 vs. 1.16, 0.91, 0.41 ng/mL). The median magnitude of the AMH levels decline after 1st, 2nd, and 3rd chemotherapy cycles were 51.2%, 69.4%, and 84.6% (p<0.001), respectively. AMH variation was associated with the basal AMH level, but not with age, βhCG at diagnosis and menstrual status.
    Conclusion: Our study has shown that the serum AMH levels declined rapidly and steadily in all patients during chemotherapy for GTN. Although AMH cannot be used to monitor fertility potential lonely, these new studies improve our knowledge of ovarian toxicity and ovarian reserve during chemotherapy and strongly support the use of fertility preservation strategies.
