Mosquito-transmitted diseases pose a threat for a great portion of the world population. Chemical insecticides are the main tool for mosquito control. Heavy dependence on chemicals created several problems such as resistance development in many mosquito species, environmental effects, and human health issues. Other tools for mosquito control were developed and used in some parts of the world. Ribonucleic acid interference (RNAi) is a reverse genetic mechanism that was recently introduced as a new tool for pest control. Regarding mosquito, RNAi was used to study gene function and to discover genes that can be used as targets for control purposes. Several delivery methods are used to induce RNAi in mosquito larvae. Some methods such as injection and soaking are used routinely in RNAi research but have no application in the field. Other methods such as nanoparticles and microbes have some characteristics that make them good candidates for field application. In this report, we will focus on delivery methods for RNAi in mosquito larvae and will give examples for each method.

Purpose: Rare cancers are defined as those for which there are less than 15 cases per 100,000 in the population annually. While much progress in detection and treatment has been made over the past decade for many rare cancers, less progress has been made in understanding survivorship needs. The objective of this study was to characterize the National Institutes of Health (NIH) cancer survivorship grant portfolio focused on rare cancers and to identify gaps specific to this area of science.

Introduction: Cesarean deliveries account for approximately one-third of all births in Germany, prompting ongoing discussions on cesarean section rates and their connection to medical staffing and birth volume. In Germany, the majority of departments integrate obstetric and gynecological care within a single department.
Methods: The analysis utilized quality reports from German hospitals spanning 2015 to 2019.

Extracellular vesicles (EVs) have been demonstrated to own the advantages in evading phagocytosis, crossing biological barriers, and possessing excellent biocompatibility and intrinsic stability. Based on these characteristics, EVs have been used as effective therapeutic carriers for drug delivery, but the low drug loading capacity greatly limits further applications. Herein, we developed a drug loading method based on cell-penetrating peptide (CPP) to enhance the encapsulation of therapeutic reagents in EVs, and EVs-based drug delivery system achieved higher killing efficacy to tumor cells.

Rationale: Guidelines recommend patients with pulmonary arterial hypertension (PAH) be referred to pulmonary hypertension (PH) centers, but little is known about where care is actually delivered in the United States (US).
Objectives: To use prescription patterns to estimate the proportion of PAH care delivered at US PH centers and explore factors associated with location of care.
Methods: This retrospective study analyzed claims from the Komodo database in adults who received ≥1 PAH prescription between March 2021 and February 2022.

Objective: Portosystemic shunts in growth-restricted fetuses are more common than previously thought. We aimed to describe fetuses with growth restriction and transient oligohydramnios in which a congenital intrahepatic portosystemic shunt (CIPSS) was noted during follow-up.
Methods: This was a retrospective study of all fetuses diagnosed with growth restriction and transient oligohydramnios during a 5-year period in a large tertiary referral center.
