Engineering Human Circulating Monocytes/Macrophages by Systemic Deliverable Gene Editing.

Delivery of plasmid DNA to transfect human primary macrophages is extremely difficult, especially for genetic engineering. Engineering macrophages is imperative for the treatment of many diseases including infectious diseases, cancer, neurological diseases, and aging. Unfortunately, plasmid does not cross the nuclear membranes of terminally differentiated macrophages to integrate the plasmid DNA (pDNA) into their genome.

Efficacy of Video-Based Forearm Anatomy Model Instruction for a Virtual Education Environment.

Introduction: As virtual education becomes more widespread, particularly considering the recent COVID-19 pandemic, studies that assess the impact of online teaching strategies are vital. Current anatomy curriculum at Paul L. Foster School of Medicine consists of self-taught PowerPoint material, clinical vignette-centered team-based learning (dry lab), and prosection-based instruction (wet lab).

Facile Gene Delivery Derived from Branched Low Molecular Weight Polyethylenimine by High Efficient Chemistry.

Convenient methods for the preparation of gene delivery platforms based on branched low molecular weight polyethylenimine (PEI) were described. Firstly, PEI lipids, with a low molecular weight PEI headgroup and hexadecyl chain tail group, were prepared through a highly efficient ring-opening reaction of glycidyl hexadecyl ether (EpoxyC16) by amine from PEI. Then, the PEI lipids were used as a component of cationic liposomes and as a surfactant for the preparation of poly(D,L-lactide-co-glycolide) (PLGA) nanoparticle (NP) via solvent extraction/evaporation method.

Subclinical Partial Attritional Rupture of the Flexor Digitorum Profundus as an Etiology of Atraumatic Trigger Finger.

Background: Trigger finger is a relatively common clinical entity. The etiology is most often attributable to stenosing tenosynovitis though traumatic cases have been described. When trigger finger is associated with an underlying flexor tendon rupture, previous cases have reported a clear association with overt laceration or previous trauma.

Visual systemizing preference in children with autism: A randomized controlled trial of intranasal oxytocin.

Several studies have suggested that the neuropeptide oxytocin may enhance aspects of social communication in autism. Little is known, however, about its effects on nonsocial manifestations, such as restricted interests and repetitive behaviors. In the empathizing-systemizing theory of autism, social deficits are described along the continuum of empathizing ability, whereas nonsocial aspects are characterized in terms of an increased preference for patterned or rule-based systems, called systemizing.
