Context: Guidelines for use of injectable estradiol esters (valerate [EV] and cypionate [EC]) among transgender and gender diverse (TGD) individuals designated male at birth vary considerably, with many providers noting supraphysiologic serum estradiol concentrations based on current dosing recommendations.

Objectives: 1. Determine dose of injectable estradiol (subcutaneous [SC] and intramuscular [IM]) needed to reach guideline-recommended estradiol concentrations for TGD adults using EC/EV.

Historically, eating disorders (EDs) have been conceptualized from a female-centric lens. However, consistent research demonstrates that EDs afflict individuals across the gender spectrum, including cismales and gender-diverse individuals. Despite this evidence, a consensus regarding gender-sensitive assessment practices, theoretical formulations, and treatment considerations has yet to be established.

Article Synopsis
  • Cervical cancer (CC) is a leading cause of cancer in women globally, with over 500,000 new cases each year, particularly affecting those in developing countries due to high mortality rates linked to HPV infections.
  • Conventional treatments face issues like resistance and side effects, highlighting the need for innovative therapies.
  • The paper examines the cancer-immunity cycle (CIC), detailing molecular changes at each stage and exploring how these insights could inform new immunotherapeutic strategies tailored to CC, influenced by factors like HPV and histological subtype.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection triggers activation of the NLRP3 inflammasome, which promotes inflammation and aggravates severe COVID-19. Here, we report that SARS-CoV-2 induces upregulation and activation of human caspase-4/CASP4 (mouse caspase-11/CASP11), and this process contributes to NLRP3 activation. In vivo infections performed in transgenic hACE2 humanized mice, deficient or sufficient for Casp11, indicate that hACE2 Casp11-/- mice were protected from disease development, with the increased pulmonary parenchymal area, reduced clinical score of the disease, and reduced mortality.

In COVID-19, EGFR production is upregulated in the alveolar epithelial cells. EGFR overexpression further activates STAT-3 and increases lung pathology. The EGFR pathway is also one of the major nodes in pulmonary fibrosis.

Purpose: Body dissatisfaction in transgender youth (TY) may increase the risk for eating disorders. This is the first study using the Eating Disorders Examination Questionnaire (EDE-Q) to assess for eating disorder psychopathology in TY.

Methods: Youth aged 13-22 years (n = 106) presenting to a gender clinic from January 2018 to January 2019 completed the EDE-Q and answered questions on weight manipulation for gender-affirming purposes.

Eating disorders are one of the most common chronic conditions in adolescents. The clinical symptoms can mimic those of other chronic diseases including gastrointestinal and endocrine disorders. However, an eating disorder can coexist with another chronic disease, making the diagnosis and management of both conditions challenging.

Background: Fibroepithelial polyps (FEPs) are benign tumors, of possibly hormone-dependent nature, found in the vulvovaginal region of women of reproductive age.

Case: A 15-year-old adolescent girl, receiving hormonal contraceptive therapy, who presented with multiple vulvar masses with histopathology consistent with FEP.

Summary And Conclusion: The spectrum of the morphology of FEPs might make their diagnosis challenging.

Local polarization of a magnetic layer, a well-known method for storing information, has found its place in numerous applications such as the popular magnetic drawing board toy or the widespread credit cards and computer hard drives. Here we experimentally show that a similar principle can be applied for imprinting the trajectory of quantum units of flux (vortices), travelling in a superconducting film (Nb), into a soft magnetic layer of permalloy (Py). In full analogy with the magnetic drawing board, vortices act as tiny magnetic scribers leaving a wake of polarized magnetic media in the Py board.

Microchemical sensors and catalytic reactors make use of gases during adsorption in specific ways on selected materials. Fine-tuning is normally achieved by morphological control and material doping. The latter relates surface properties to the electronic structure of the bulk, and this suggests the possibility of electronic control.

Novel manganese oxide particles with complex morphologies and different nanostructures (i.e., spherical/lamellar) were synthesized by initial preparation of a coordination complex of manganese with 1,4,7,10-tetraazacyclododecane (cyclen), followed by characterization of the nanostructured oxide as a catalytic material for ethanol oxidation.

A set of poly(propylene) composites containing different amounts of copper nanoparticles (CNP) were prepared by the melt mixed method and their antimicrobial behavior was quantitatively studied. The time needed to reduce the bacteria to 50% dropped to half with only 1 v/v % of CNP, compared to the polymer without CNP. After 4 h, this composite killed more than 99.
