Background: Deep dyspareunia affects 50% of people with endometriosis. The Ohnut is a set of interlocking rings that fit over the penis/insertive object. One or more rings can be used to limit insertion depth and reduce deep dyspareunia.

Article Synopsis
  • * Participants were aged 19-49, had self-reported deep dyspareunia, and had surgically confirmed endometriosis, completing assessments on tenderness at various pelvic sites and overall acceptability of the device.
  • * Results showed high acceptability (median score 0.72) and strong reliability in tenderness scores across assessments, indicating the vaginal insert could be a useful tool for understanding and measuring deep dyspareunia severity.

Background: Endometriosis-associated deep dyspareunia is associated with reduced sexual quality of life, lower self-esteem, and impaired sexual function.

Objective: The primary objective is to assess the acceptability of a phallus length reducer (brand name: Ohnut [OhnutCo]), which is a buffer worn over the penis or a penetrating object to reduce endometriosis-associated deep dyspareunia, and the feasibility of a definitive randomized controlled trial (RCT). The secondary objective is to obtain estimates of the effectiveness of the buffer.

Modified Blalock-Thomas-Taussig shunts are typically performed with biosynthetic polytetrafluoroethylene grafts. However, biologic conduits are being increasingly investigated. We herein report a case in which a femoral artery homograft was effectively used as material for a Blalock-Thomas-Taussig shunt.

The epidermal growth factor (EGF) receptor (EGFR) is heterogeneously distributed on the cellular surface and enriched in clusters with diameters of tens of nanometers. Multivalent presentation of EGF ligand on nanoparticles (NPs) provides an approach for controlling and amplifying the local activation of EGFR in these clusters. Reactive oxygen species (ROS) have been indicated to play a role in the regulation of EGFR activation as second messengers, but the effect of nanoconjugation on EGF-mediated ROS formation and ROS-induced EGFR activation is not well established.

Severe acute respiratory distress syndrome coronavirus 2 (COVID-19) is the cause of the current pandemic, which remains a tremendous cause of morbidity and mortality worldwide. Although there are numerous trials underway, there is currently no medication known to cure the infection. Nonsteroidal anti-inflammatory drugs (NSAIDs) are inexpensive, widely available medications with antiviral and anti-inflammatory properties and may have utility as an adjunct therapy to improve outcomes in patients with severe COVID-19 infection.

To reconstruct the defects caused by craniectomies autologous, bone grafting was usually used, but they failed most commonly due to bone resorption, infections and donor-site morbidity. In the present investigation, an effort has been made for the first time to check the feasibility and advantage of using hydroxyapatite (HAp) coated e-glass as component of bone implants. Sol-gel synthesized coatings were found to be purely hydroxyapatite from XRD with graded and interconnected pores all over the surface observable in TEM.

Spatial clustering of cell membrane receptors has been indicated to play a regulatory role in signal initiation, and the distribution of receptors on the cell surface may represent a potential biomarker. To realize its potential for diagnostic purposes, scalable assays capable of mapping spatial receptor heterogeneity with high throughput are needed. In this work, we use gold nanoparticle (NP) labels with an average diameter of 72.

The superior frontal gyrus (SFG) is thought to contribute to higher cognitive functions and particularly to working memory (WM), although the nature of its involvement remains a matter of debate. To resolve this issue, methodological tools such as lesion studies are needed to complement the functional imaging approach. We have conducted the first lesion study to investigate the role of the SFG in WM and address the following questions: do lesions of the SFG impair WM and, if so, what is the nature of the WM impairment? To answer these questions, we compared the performance of eight patients with a left prefrontal lesion restricted to the SFG with that of a group of 11 healthy control subjects and two groups of patients with focal brain lesions [prefrontal lesions sparing the SFG (n = 5) and right parietal lesions (n = 4)] in a series of WM tasks.

We have established an animal model for olanzapine-induced body weight gain, and used it to explore the relation between this weight gain, excessive food consumption, gross motor activity, and macronutrient choice. Female Sprague-Dawley rats received olanzapine (OLAN) or diluent (1.2mg/kg per day) via gavage for 10 days.

Budded virions (BV) of the baculovirus Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) contain a major envelope glycoprotein known as GP64, which was previously shown to be palmitoylated. In the present study, we used truncation and amino acid substitution mutations to map the palmitoylation site to cysteine residue 503. Palmitoylation of GP64 was not detected when Cys503 was replaced with alanine or serine.
