Introduction: Postpartum depression (PPD) is the most prevalent postpartum complication, significantly diminishing sexual function in marital life. It may result in visible developmental delays, social and interactive challenges in infants, and marital stress leading to divorce. The present study aimed to examine the effect of organic selenium ( yeast enriched with sodium selenite) and sodium selenite on PPD and sexual satisfaction.

Human Immunodeficiency Virus (HIV) infection is among the most challenging issues in the healthcare system, presenting significant financial and hygiene problems with a wide range of clinical manifestations. Despite the hopeful outcomes of Antiretroviral Therapies (ARTs), the current strategies for the treatment of patients with HIV infection have not shown clinical significance for all subjects, which is mainly due to the complexity of the disease. Therefore, the need for collaborative and interdisciplinary research focused on deciphering the multifaceted cellular, and molecular immunopathogenesis of HIV remains essential in the development of innovative and more efficacious therapeutic approaches.

Oligonucleotide-based nanogels, as nascent biomaterials, possess several unique functional, structural, and physicochemical features with excellent drug-loading capacity and high potential for cancer gene therapy. Ongoing studies utilizing oligonucleotide-based nanogels hold great promise, as these cutting-edge nanoplatforms can be elegantly developed with predesigned oligonucleotide sequences and complementary strands which are self-assembled or chemically crosslinked leading to the development of nanogels with predictable shape and tunable size with the desired functional properties. Current paper provides a summary of the properties, preparation methods, and applications of oligonucleotide-based nanogels in cancer therapy.

Despite the recent advances in the development of bone graft substitutes, treatment of critical size bone defects continues to be a significant challenge, especially in the elderly population. A current approach to overcome this challenge involves the creation of bone-mimicking scaffolds that can simultaneously promote osteogenesis and angiogenesis. In this context, incorporating multiple bioactive agents like growth factors, genes, and small molecules into these scaffolds has emerged as a promising strategy.

Article Synopsis
  • CHO cells are integral for recombinant biotherapeutic production, yet their low productivity is primarily hindered by apoptosis, prompting research to enhance their performance.* -
  • The study utilized CRISPR/Cas9 technology to disrupt the BAX gene, resulting in increased cell viability and higher erythropoietin production rates in manipulated CHO cells, even under stress conditions.* -
  • The findings suggest that editing anti-apoptotic genes like BAX can significantly improve CHO cell productivity, indicating a promising avenue for more efficient biomanufacturing processes.*

Background: This study describes the launching of a unit for continuous kangaroo mother care (KMC) in a teaching hospital (Taleghani) in Iran.

Methods: We used a participatory three-stage action research approach to establish a unit for continuous KMC: design (needs identification and planning for change); implementation (and reflection); and evaluation (and institutionalization). As part of the design and implementation stages, individual and focus group interviews were conducted with mothers, physicians, nurses, other healthcare personnel and policy makers.

Exploring efficient strategies to eradicate the tumor tissue and enhance patient outcomes still remained a serious challenge. Systemic toxicity of the current chemotherapeutics and their low concentration in the tumor site limited reaching a practical approach in their administration and combinational therapy. Besides, complicated delivery platforms could not receive the marketing approval due to difficulties in scale up procedures.

Multiple Sclerosis (MS) is an autoimmune disease with complicated immunopathology which necessitates considering multifactorial aspects for its management. Nano-sized pharmaceutical carriers named nanoparticles (NPs) can support impressive management of disease not only in early detection and prognosis level but also in a therapeutic manner. The most prominent initiator of MS is the domination of cellular immunity to humoral immunity and increment of inflammatory cytokines.

For the first time, we synthesized the co-delivery nanopolymers using zein protein as the core and chitosan polysaccharide as the shell to deliver curcumin (Cur) and berberine (Ber) in MDA-MB-231 breast cancer cells. It has been shown that Cur and Ber altogether have synergistic effects on multiple cancers. Herein, the curcumin-zein-berberine-chitosan (Cur-Z-Ber-Ch) nanoparticles were fabricated and their organization procedure was reported.

Injectable in situ forming hydrogels are amongst the efficient local drug delivery systems for cancer therapy. Providing a 3D hydrogel network within the target tissue capable of sustained release of the chemotherapeutics made them attractive candidates for increasing the therapeutic index. Remarkable swelling properties, mechanical strength, biocompatibility, wide composition variety and tunable polymeric moieties have led to preparation of injectable hydrogels which also could be used as cavity adaptive chemotherapeutic-loaded implants to prevent post -surgical cancer recurrence.

Kangaroo mother care (KMC), as a complement to incubator care, is one of the ten recommendations of the World Health Organization (WHO) for the care of preterm infants. The KMC stabilizes the heart rate, improves oxygen saturation, makes weight gain better, and reduces crying in the infant. In order to launch KMC unit, the barriers for implementing this type of care should be recognized.

The novel coronavirus outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was recognized in late 2019 in Wuhan, China. Subsequently, the World Health Organization declared coronavirus disease 2019 (COVID-19) as a pandemic on 11 March 2020. The proportion of potentially fatal coronavirus infections may vary by location, age, and underlying risk factors.

Background: The efficacy of continuous kangaroo mother care (C-KMC) in reducing neonatal mortality and morbidity among low birthweight and premature infants has been confirmed. Despite the recommendations of the World Health Organization, UNICEF, and the Ministry of Health of Iran to use C-KMC for eligible hospitalized neonates, this type of care is not performed due to implementation problems. This protocol aims to describe the design, implementation, and assessment of C-KMC in one tertiary hospital by means of participatory action research.

To efficiently deliver the chemotherapeutics to the tumor tissue and minimize the associated adverse effects, nucleolin targeted hybrid nanostructure based on hollow mesoporous silica nanoparticles (HMSNs) were fabricated. To provide the controlled, sustained drug release and enhance blood circulation, the surface of doxorubicin-encapsulated HMSNs were coated with acetylated carboxymethyl cellulose (Ac-CMC) and then covalently conjugated to AS1411 aptamer for guided drug delivery to nucleolin overexpressed cancerous cells. In vitro cellular uptake and cytotoxicity studies confirmed that AS1411 aptamer specifically targets nucleolin overexpressing MCF-7 and C26 cells.

SN38 is an active metabolite of irinotecan, which was approved for clinical use in metastatic colorectal cancers. However, poor aqueous solubility and inactivation at pH below 6 are the main limitations of its use. In the current study, we separately conjugated α-, β- and γ-cyclodextrins to graphene oxide sheets to produce stable, biocompatible nanocarriers for SN38 delivery.

Bone nonunion may occur when the fracture is unstable, or blood supply is impeded. To provide an effective treatment for the healing of nonunion defects, we introduce an injectable osteogenic hydrogel that can deliver cells and vasculogenic growth factors. We used a silicate-based shear-thinning hydrogel (STH) to engineer an injectable scaffold and incorporated polycaprolactone (PCL) nanoparticles that entrap and release vasculogenic growth factors in a controlled manner.
