Au on in 2 O 3‐x /TiO 2 (110): A Highly Active and Selective Catalyst for the Conversion of CO 2 to Methanol

ABSTRACT Methanol production by carbon dioxide hydrogenation is a promising route for supplying industrial fuel demands, but achieving high methanol selectivity remains challenging due to competing favorable reactions. Here, we investigate model Au/In 2 O 3‐x /TiO 2 (110) catalys...

Divergent Human Papillomavirus Genotype Spectra in Three Indigenous Communities of Venezuela: Implications for Vaccine Choice and Cervical Screening

Background: Genotype-resolved data on human papillomavirus (HPV) are almost absent for Venezuelan indigenous women. Methods: We studied 260 women from La Guajira (Wayuu, n = 94), Maniapure (Eñepa, n = 141), and Delta Amacuro (Warao, n = 25), processing all self-collected samples...

Comparative effectiveness of stump closure methods during laparoscopic appendectomy: a systematic review and network meta-analysis of randomized controlled trials with CINeMA assessment

Laparoscopic appendectomy is one of the most performed emergency surgical procedures worldwide, and secure appendiceal stump closure remains a key step for ensuring favorable postoperative outcomes. Multiple closure techniques are currently available; however, comparative evidenc...

Occupational Risk of Histoplasma capsulatum Exposure among Field Biologists in Ecuador: Evidence from Skin Testing and Serology

Abstract Histoplasma capsulatum, a dimorphic fungus, is the causative agent of histoplasmosis, a respiratory disease with a wide clinical spectrum ranging from asymptomatic infection to severe pulmonary or disseminated disease. Although Ecuador is recognized as an endemic country...

“Radix High Spreader Grafts: A Technique for Dorsal Augmentation and Axis Correction”

The Radix High Spreader Graft is designed to restore dorsal alignment and improve the radix-dorsum transition by extending traditional spreader grafts superiorly into the bony radix region. By anchoring the graft within 2-mm osseous grooves created with a micromotor, this techniq...

Surgical anatomy, biomechanics and clinical outcomes of latissimus dorsi transfer for irreparable rotator cuff tears: a review

BACKGROUND: Latissimus dorsi transfer is a well-established joint-preserving option for irreparable rotator cuff tears in young, active patients without glenohumeral arthritis. Originally described by Gerber in 1988 for posterosuperior tears, indications now also include anterosu...
