Novel Memories of Motherhood: Childbirth Lived Experiences of Mothers with Coronavirus Disease 2019 (COVID-19).

Introduction: The critical coronavirus pandemic presents a global challenge with dimensions yet unknown, underscoring the essential need to comprehend the lived experiences, especially for vulnerable groups. This study delves into the childbirth experiences of mothers dealing with coronavirus disease 2019 (COVID-19).

Methods: Employing hermeneutic phenomenology, this qualitative research was conducted at Mashhad University of Medical Sciences (Iran).

High-risk pregnant women's experiences of the receiving prenatal care in COVID-19 pandemic: a qualitative study.

Background: Women with high-risk pregnancies are among the most vulnerable groups that require additional precautionary measures against the spread of COVID-19 plus receiving prenatal care. Yet, there is limited information on the status of prenatal care in women with high-risk pregnancies. The purpose of this study was to explore the experiences of women with high-risk pregnancies who were receiving prenatal care during the COVID-19 pandemic.

Placental infection with SARS-CoV-2, analysis of 16 cases and literature review.

Purpose: Since December 2019, the whole world has been affected by coronavirus [severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)]. However, the effects of COVID-19 infection on pregnancy and fetal transmission are still unclear. Therefore, this study was conducted to evaluate placenta samples regarding detection of SARS-CoV-2 RNA in women affected with COVID-19.

The performance of micro-meso-pore HY zeolite for supporting Mo toward oxidation of dibenzothiophene.

A uniformly distribution of 3 wt.% Mo (with tetrahedral coordination) on a commercial HY zeolite having both micro- and meso-pores, provided a new active catalyst which resulted 100% removal of DBT in this work. Respectively, HO and acetonitrile were used as the oxidant and extraction solvent for oxidative desulfurization (ODS) at a mild condition.

Development and Characterization of Nanoliposomal Hydroxyurea Against BT-474 Breast Cancer Cells.

Hydroxyurea (HU) is a well-known chemotherapy drug with several side effects which limit its clinical application. This study was conducted to improve its therapeutic efficiency against breast cancer using liposomes as FDA-approved drug carriers. PEGylated nanoliposomes-containing HU (NL-HU) were made via a thin-film hydration method, and assessed in terms of zeta potential, size, morphology, release, stability, cellular uptake, and cytotoxicity.

Preparation, characterization, and cytotoxic effects of liposomal nanoparticles containing cisplatin: an in vitro study.

Cisplatin is a chemotherapeutic agent used for treating various malignancies. The study aimed to prepare pegylated liposomal cisplatin and evaluate its efficacy against human breast cancer cell line MCF-7. Drug-loaded nanoparticles were synthesized by reverse phase evaporation technique.

A Novel Label-Free microRNA-155 Detection on the Basis of Fluorescent Silver Nanoclusters.

In this paper, a new approach for microRNA-155 (miRNA-155) detection was described based on the fluorescence quenching of oligonucleotide-templated silver nanoclusters (DNA-AgNCs). The specific DNA scaffold with two different nucleotides fragments were used: one was enriched with a cytosine sequence fragment (C12) that could result in DNA-AgNCs with a high quantum yield via a chemical reduction method, and the other was the probe fragment (5- CUGUUAAUGCUAAUCGUG-3) which could selectively bind to the miRNA-155. Thus, the as-prepared AgNCs could exhibit quenched fluorescence when binding to the target miRNA-155.

Facilitated and selective oxidation of thiophenic sulfur compounds using MoOx/Al₂O₃-H₂O₂ system under ultrasonic irradiation.

Oxidative desulfurization of thiophenic sulfur compounds of benzothiophene (BT), dibenzothiophene (DBT) and 4,6-dimethyl dibenzothiophene (4,6-DMDBT) with MoOx/Al₂O₃ catalyst and H₂O₂ oxidant has been facilitated and more selective under ultrasonic irradiation. The catalyst with the optimum 10% of Mo loading consisted of isolated tetrahedral molybdenum oxide species based on FTIR analysis. The increase of Mo loading to 15% and 20% caused to generation of polymolybdate and MoO₃ crystals which decreased desulfurization activity.

Views of patients undergo hematopoietic stem cell transplantation on their basic needs.

Background: Today, hematopoietic stem cells transplantation (HSCT) has been accepted as a therapeutic approach and is widely applied in many patients with disorders of hematopoietic systems or patients with malignancies. Concomitant use of this therapeutic approach with long term chemotherapeutic procedures and hospitalization requires special care. This study was conducted to examine basic needs of patients after HSCT.

Investigation of process variables and intensification effects of ultrasound applied in oxidative desulfurization of model diesel over MoO3/Al2O3 catalyst.

A new heterogeneous sonocatalytic system consisting of a MoO3/Al2O3 catalyst and H2O2 combined with ultrasonication was studied to improve and accelerate the oxidation of model sulfur compounds of diesel, resulting in a significant enhancement in the process efficiency. The influence of ultrasound on properties, activity and stability of the catalyst was studied in detail by means of GC-FID, PSD, SEM and BET techniques. Above 98% conversion of DBT in model diesel containing 1000 μg/g sulfur was obtained by new ultrasound-assisted desulfurization at H2O2/sulfur molar ratio of 3, temperature of 318 K and catalyst dosage of 30 g/L after 30 min reaction, contrary to the 55% conversion obtained during the silent process.
