The inclusion criteria were being >18 years old, having a recurrent anterior shoulder dislocation with a Bankart lesion, and having a minimum 2-year follow-up.

Spinal stabilization exercises for transversus abdominis and lumbar multifidus thickness via telerehabilitation and face-to-face approaches in patients with nonspecific chronic neck pain: a randomized controlled trial.

Background/aim: Strengthening the muscles of the lumbar region in individuals with neck pain may be protective against future back problems. In addition, telerehabilitation applications, which gained momentum in the literature and clinical practice during the COVID-19 pandemic, are among the applications preferred by patients thanks to their various advantages.

Short-lived calcium carbonate precursors observed in situ via Bullet-dynamic nuclear polarization.

The discovery of (meta)stable pre-nucleation species (PNS) challenges the established nucleation-and-growth paradigm. While stable PNS with long lifetimes are readily accessible experimentally, identifying and characterizing early-stage intermediates with short lifetimes remains challenging. We demonstrate that species with lifetimes ≪ 5 s can be characterized by nuclear magnetic resonance spectroscopy when boosted by 'Bullet' dynamic nuclear polarization (Bullet-DNP).

Branched Polymeric Prenucleation Assemblies Initiate Calcium Phosphate Precipitation.

The formation of crystalline calcium phosphate (CaP) has recently gained ample attention as it does not follow the classic nucleation-and-growth mechanism of solid formation. Instead, the precipitation mechanisms can involve numerous intermediates, including soluble prenucleation species. However, structural features, stability, and transformation of such solution-state precursors remain largely undisclosed.

Adrenomedullin has no effect on segmental bone defect healing but increases bone mineral density in rat model.

Objective: This study aimed to investigate the effect of adrenomedullin on the healing of the segmental bone defect in a rat model.

Methods: Thirty-six Wistar rats were randomly divided into 6 groups based on follow-up periods and administered a dose of adrenomedullin hormone. In each group, bilaterally, a 2-mm bone defect was created at the diaphysis of the radius.

Biphasic NMR of Hyperpolarized Suspensions-Real-Time Monitoring of Solute-to-Solid Conversion to Watch Materials Grow.

Nuclear magnetic resonance (NMR) spectroscopy is a key method for the determination of molecular structures. Due to its intrinsically high (, atomistic) resolution and versatility, it has found numerous applications for investigating gases, liquids, and solids. However, liquid-state NMR has found little application for suspensions of solid particles as the resonances of such systems are excessively broadened, typically beyond the detection threshold.

Translation and Cross-Cultural Adaptation of the Anterior Cruciate Ligament Donor Site Morbidity Questionnaire Into Turkish.

This study aimed to translate the ACL Donor Site Morbidity (ACL-DSM) questionnaire into Turkish and assess the reliability and validity of the Turkish version of the ACL-DSM questionnaire (ACL-DSM-Tr) among individuals following anterior cruciate ligament (ACL) reconstruction. The process involved forward and back-translation, cultural adaptation, and validation of the ACL-DSM-Tr questionnaire on ninety-nine patients (mean age 30.73 ± 8.

Asymmetric Transfer Hydrogenation as a Key Step in the Synthesis of the Phosphonic Acid Analogs of Aminocarboxylic Acids.

α-Aminophosphonic acids have a remarkably broad bioactivity spectrum. They can function as highly efficient transition state mimics for a variety of hydrolytic and angiotensin-converting enzymes, which makes them interesting target structures for synthetic chemists. In particular, the phosphonic acid analogs to α-aminocarboxylic acids (P AAs) are potent enzyme inhibitors, but many of them are only available by chiral or enzymatic resolution; sometimes only one enantiomer is accessible, and several have never been prepared in enantiopure form at all.

Effects of Different Frequencies of Physical Therapy Visits on Shoulder Function After Arthroscopic Rotator Cuff Repair.

Objective: There is no consensus about the optimal frequency of patient visits during the rehabilitation program after arthroscopic rotator cuff repair (ARCR). This study aimed to investigate the short- and long-term effects of high-frequency (HF) and low-frequency (LF) visits of the patients in the first 12 weeks of rehabilitation after ARCR.

Methods: This was a quasi-randomized study with 2 parallel groups.

Investigation the Effect of Human Recombinant Epidermal Growth Factor on Rotator Cuff Healing: An Experimental Model.

 To investigate the effectiveness of human recombinant epidermal growth factor in the healing of rotator cuff tear in the rabbit shoulder.  Rotator cuff tears (RCTs) were experimentally created on both shoulders of 20 New Zealand rabbits. The rabbits were divided into the following groups: RCT (sham group;  = 5), RCT + EGF (EGF group;  = 5), RCT + transosseous repair (repair group;  = 5), and RCT + EGF + transosseous repair (combined repair + EGF group;  = 5).

Boron nitride nanofiber/Zn-doped hydroxyapatite/polycaprolactone scaffolds for bone tissue engineering applications.

In this study, Zn doped hydroxyapatite (Zn HA)/boron nitride nanofiber (BNNF)/poly-ε-caprolactone (PCL) composite aligned fibrous scaffolds are produced with rotary jet spinning (RJS) for bone tissue engineering applications. It is hypothesized that addition of Zn HA and BNNF will contribute to cell viability as well as mechanical and osteogenic properties of the PCL scaffolds. Zn HA was synthesized by mixing Ca and P sources followed by sonication and aging whereas BNNF was obtained by the reaction of melamine with boric acid followed by freeze-drying for annealing of fibers.

Hypotheses: Performance tests would reveal insufficiency in the functional capacity of shoulder 6 months after stabilization surgery.

Study Design: Prospective cohort study.

Operative treatment in non-emergency sports injuries: a sports medicine clinic experience.

Purpose: To elucidate referrals from sports medicine clinic (SMC) to orthopedics, consensus rates among physicians and surgeons on surgical need in these patients, and reasoning of the patients who refused to have surgery despite the recommendations by both groups in non-emergency sports injury patients.

Methods: We conducted a retrospective cohort analysis by using the administrative and referral records of a sports medicine clinic for the 15 months between October 2017 and January 2019. Gender, age, diagnosis, and type of sport were compared between two groups (patients referred to orthopedics vs patients treated in SMC).

Frémy's Salt as a Low-Persistence Hyperpolarization Agent: Efficient Dynamic Nuclear Polarization Plus Rapid Radical Scavenging.

Nuclear magnetic resonance (NMR) spectroscopy is a key technique for molecular structure determination in solution. However, due to its low sensitivity, many efforts have been made to improve signal strengths and reduce the required substrate amounts. In this regard, dissolution dynamic nuclear polarization (DDNP) is a versatile approach as signal enhancements of over 10 000-fold are achievable.

Inversion of Hyperpolarized C NMR Signals through Cross-Correlated Cross-Relaxation in Dissolution DNP Experiments.

Dissolution dynamic nuclear polarization (DDNP) is a versatile tool to boost signal amplitudes in solution-state nuclear magnetic resonance (NMR) spectroscopy. For DDNP, nuclei are spin-hyperpolarized "" in a dedicated DNP device and then transferred to an NMR spectrometer for detection. Dramatic signal enhancements can be achieved, enabling shorter acquisition times, real-time monitoring of fast reactions, and reduced sample concentrations.
