The objective of this study was to share the experiences of Hispanic and Black families with CHD to better understand their needs.

Arthroscopic Suprapectoral Biceps Tenodesis Using an Onlay Technique.

Tenodesis of the long head of biceps is a common shoulder surgical procedure. Tenodesis can be performed either arthroscopically or open and within the glenohumeral joint, within the bicipital groove, or below the pectoralis major tendon insertion. Arthroscopic tenodesis of the biceps tendon reduces the risk of infection.

Arthroscopic Extensor Carpi Radialis Brevis Tenotomy Under Local Anesthesia for Refractory Lateral Epicondylitis.

Refractory lateral epicondylitis poses significant challenges for patients and doctors. Whereas traditional surgical treatments involve open resection and extensor carpi radialis brevis (ECRB) muscle debridement, arthroscopic surgery advancements offer a more refined approach. Numerous surgical methods are used to treat lateral epicondylitis.

Arthroscopic Repair of Subscapularis Tendon Using a Percutaneous Continuous Sewing Machine-Like Suture Technique Through a Single Working Portal.

Tearing of the subscapularis tendon is a common shoulder injury that typically requires arthroscopic repair. The suture-passing device is a standard tool for repairing the subscapularis tendon. However, it poses the risk of device breakage and may cause additional damage to the tendon.

Endoscopic Technique: Sciatic Neurolysis and Piriformis Tendon Release for Treating Piriformis Syndrome.

Piriformis syndrome (PS) is an underdiagnosed condition, caused by entrapment of the sciatic nerve by the piriformis muscle tendon and adhesions in the deep gluteal space. We present a step-by-step endoscopic technique with the patient in a prone position through a posterior approach. This approach provides improved orientation for tracking the sciatic nerve from distal to proximal, facilitating the release of all adhesions and concluding with a piriformis tendon release.

The Mason-Loop for Single-Row Full-Thickness Rotator Cuff Repair.

Rotator cuff injuries are common and can lead to pain and functional limitation of the shoulder, sometimes requiring surgical procedure. We describe a surgical approach combining the modified Mason-Allen and lasso-loop techniques for the repair of rotator cuff injuries. This hybrid approach brings the 2 advantages of each suture: the compression provided by the loop and the large quantity of tendons caught by the Mason-Allen in a single repair row.

All-Inside Arthroscopic Tie-Grip Suture Repair for Radial Tear in the Midbody of Lateral Meniscus Using an All-Inside Device and Slotted Cannula.

Inside-out repair of meniscal tears is the gold standard surgical approach; however, its use is limited by the need for a posterior incision and neurovascular risk. In this Technical Report, we present details of the all-inside arthroscopic tie-grip approach for repairing a radial tear of the midbody of the lateral meniscus using an all-inside device (TRUESPAN) and a slotted cannula. In contrast to the inside-out approach, this technique helps reduce surgical invasiveness and provides stable fixation as the vertical mattress sutures bundle the circumferential fibers and act as rip stops for the horizontal sutures.

Anterior Cruciate Ligament Stump Elongation Technique for Anterior Cruciate Ligament Restoration.

There is renewed interest in anterior cruciate ligament (ACL) preservation techniques. Prior studies have shown good outcomes and low failure rates with ACL preservation in patients with good tissue quality and more proximal tears. We describe a technique intended to assist surgeons in obtaining maximal length of the ACL stump during ACL preservation surgery.

Social network analysis as a new tool to measure academic impact of physicians.

Introduction: H-index is a widely used metric quantifying a researcher's productivity and impact based on an author's publications and citations. Though convenient to calculate, h-index fails to incorporate collaborations and interrelationships between physicians into its assessment of academic impact, leading to limited insight into grouped networks. We present social network analysis as a tool to measure relationships between physicians and quantify their academic impact.

Five-year comparison of clinical and echocardiographic outcomes of pure aortic stenosis with pure aortic regurgitation or mixed aortic valve disease in the COMMENCE trial.

Genetic diversity and population structure analysis of short-day onions using molecular markers in association with resistance to Fusarium basal rot.

In this research, we analyzed Random Amplified Polymorphic DNA (RAPD), Inter Simple Sequence Repeats (ISSR) and Sequence-related amplified polymorphism (SRAP) markers to evaluate the genetic diversity of eighteen different onion genotypes with various resistant levels to FOC. The results showed that the polymorphism means between RAPD primers was 61.11 to 81.

g-C3N4 S-Scheme Homojunction through van der Waals Interface Regulation by Intrinsic Polymerization Tailoring for Enhanced Photocatalytic H2 Evolution and CO2 Reduction.

The effective S-scheme homojunction relies on the precise regulation of band structure and construction of advantaged charge migration interfaces. Here, the electronic structural properties of g-C3N4 were modulated through meticulous polymerization of self-assembled supramolecular precursors. Experimental and DFT results indicate that both the intrinsic bandgap and surface electronic characteristics were adjusted, leading to the formation of an in-situ reconstructed homojunction interface facilitated by intrinsic van der Waals forces.

Mangiferin Attenuates Myocardial Ischemia Reperfusion Injury by Regulating the GAS6/Axl Signaling Pathway.

Ischemia reperfusion-induced myocardial injury is a prominent pathological feature in patients with coronary artery disease, contributing to significant mortality and morbidity rates. Mangiferin (MGF), the main active ingredient extracted from Anemarrhena asphodeloides Bge, has anti-inflammatory, anti-oxidation, anti-diabetes, and anti-tumor effects. The present study confirmed that the GAS6/Axl pathway was identified as a promising novel target for the treatment of myocardial ischemia reperfusion (IR) injury.

Isomer-Effects of Aminophenol Decorated Gold Nanoclusters for HO Photoproduction via Two-Step One-Electron Oxygen Reduction Reaction.

Gold (Au) nanoclustersare promising photocatalysts for biomedicine, sensing, and environmental remediation. However, the short carrier lifetime, inherent instability, and unclear charge transfer mechanism hinder their application. Herein, the Au nanoclusters decorated with three different isomers of o-Aminophenol, m-Aminophenol, and p-Aminophenol are synthesized, namely o-Au, m-Au, and p-Au, which achieve efficient hydrogen peroxide (HO) photoproduction through two-step one-electron oxygen reduction reaction (ORR).

Coupling ion exclusion and interaction screening within sub-nanoconfinement channels in novel porous material membranes hold great potential to realize highly efficient ion sieving, particularly for high-performance lithium-ion extraction. Diverse kinds of advanced membranes have been previously reported to realize this goal but with moderate performance and complex operations gained. Herein, these issues are circumvented by preparing the consecutive and intact imine-linked three-dimensional covalent organic framework (i.

Modulation of Donor in Purely Organic Triplet Harvesting AIE-TADF Photosensitizer for Image-guided Photodynamic Therapy.

Image-guided photodynamic therapy is acknowledged as one of the most demonstrative therapeutic modalities for cancer treatment because of its high precision, non-invasiveness, and improved imaging ability. A series of purely organic photosensitizers denoted as BTMCz, BTMPTZ, and BTMPXZ, have been designed and synthesized and are found to exhibit both thermally activated delayed fluorescence and aggregation-induced emission simultaneously. Experimental and theoretical studies are combined to reveal that modulation of the donor of the photosensitizer enables distinct thermally activated delayed fluorescence via a second-order spin-orbit perturbation mechanism involving lowest singlet charge-transfer and higher-lying triplet locally excited states, respectively.
