- Myofascial chains of the upper limb: A systematic review of anatomical studies. [Review]
- CAClin Anat 2019 Jun 21
- CONCLUSIONS: There is good evidence for direct serial tissue continuity extending from the neck and shoulder region to the forearm. Despite this intriguing finding, which could have implications for health professionals and the treatment of musculoskeletal disorders, further research is needed to establish the mechanical relevance of the identified myofascial chains.

- Increased Stiffness of Rotator Cuff Tendons in Frozen Shoulder on Shear Wave Elastography. [Journal Article]
- JUJ Ultrasound Med 2019 Jun 19
- CONCLUSIONS: The SWE values of the both SSp and ISp tendons increased in the freezing phase, and that of the CHL also increased in the frozen phase. Not only the change in thickness of the capsule but also the change in stiffness of the rotator cuff may correlate with frozen shoulder.

A total of 449 barley accessions were phenotyped for Pyrenophora teres f. teres resistance at three locations and in greenhouse trials. Genome-wide association studies identified 254 marker-trait associations corresponding to 15 QTLs. Net form of net blotch is one of the most important diseases of barley and is present in all barley growing regions. Under optimal conditions, it causes high yield losses of 10-40% and reduces grain quality. The most cost-effective and environmentally friendly way to prevent losses is growing resistant cultivars, and markers linked to effective resistance factors can accelerate the breeding process. Here, 449 barley accessions expressing different levels of resistance comprising landraces and commercial cultivars from the centres of diversity were selected. The set was phenotyped for seedling resistance to three isolates in controlled-environment tests and for adult plant resistance at three field locations (Belarus, Germany and Australia) and genotyped with the 50 k iSelect chip. Genome-wide association studies using 33,818 markers and a compressed mixed linear model to account for population structure and kinship revealed 254 significant marker-trait associations corresponding to 15 distinct QTL regions. Four of these regions were new QTL that were not described in previous studies, while a total of seven regions influenced resistance in both seedlings and adult plants.
- Hip Arthroscopy of a Painful Hip with Borderline Dysplasia. [Journal Article]
- HPHip Pelvis 2019; 31(2):102-109
- CONCLUSIONS: The results of the current study indicate that arthroscopic management may be beneficial for a subset of patients with borderline dysplasia; however, the dissatisfaction rate associated with this treatment approach may be as high as 40%. The poor preoperative pain score appears to be the sole indicator for poor outcomes.

The profunda brachii artery also referred to as the deep brachial artery, is the first and largest branch of the brachial artery. It originates from the posterior portion of the brachial artery, just inferior to the lower border of the teres major muscle. It then traverses the triangular interval into the posterior compartment of the arm along with the radial nerve. Once in the posterior compartment, the profunda brachii artery gives off an arterial branch that anastomoses with the posterior circumflex humeral artery before continuing inferiorly along the radial sulcus (radial groove). Below the inferior border of the latissimus dorsi muscle, it branches into the radial collateral artery and middle collateral artery. The radial collateral artery further divides into the anterior radial collateral artery and the posterior radial collateral artery. The anterior radial collateral artery anastomoses with the radial recurrent artery while the middle collateral artery and posterior radial collateral artery both anastomose with the recurrent interosseous artery.

Pipecolic acid is an essential component of systemic acquired resistance, priming resistance in Arabidopsis thaliana against (hemi-)biotrophic pathogens. Here, we studied the potential role of pipecolic acid in bacteria-induced systemic immunity in barley. Exudates of barley leaves infected with the systemic immunity-inducing pathogen Pseudomonas syringae pv. japonica induced immune responses in A. thaliana. The same leaf exudates contained elevated pipecolic acid levels compared to those of mock-treated barley leaves. Exogenous application of pipecolic acid induced resistance in barley against the hemi-biotrophic bacterial pathogen Xanthomonas translucens pv. cerealis. Furthermore, both a systemic immunity-inducing infection and exogenous application of pipecolic acid enhanced the resistance of barley against the biotrophic powdery mildew pathogen Blumeria graminis f. sp. hordei. In contrast to a systemic immunity-inducing infection, pipecolic acid application did not influence lesion formation by a systemically applied inoculum of the necrotrophic fungus Pyrenophora teres. Nitric oxide (NO) levels in barley leaves increased after pipecolic acid application. Furthermore, Xanthomonas translucens pv. cerealis induced the accumulation of superoxide anion radicals and this response was stronger in pipecolic acid-pretreated compared to mock-pretreated plants. Thus, the data suggest that pipecolic acid induces barley innate immune responses by triggering NO and priming reactive oxygen species accumulation.

The anterior or volar compartment of the forearm contains eight muscles: five belong to the superficial group (pronator teres, flexor carpi radialis, palmaris longus, flexor digitorum superficialis and flexor carpi ulnaris), and three to the deep group (flexor digitorum profundus, flexor pollicis longus and pronator quadratus). Knowledge of the topographic anatomy is essential for correct performance of ultrasound (US) examinations and correct interpretation of the images provided.

An important percentage of the patient, undergoing primary or revisional bariatric surgery after sleeve gastrectomy, presents symptomatic gastroesophageal reflux disease (GERD). When and how surgical reinforcement of the lower esophageal sphincter should be performed to prevent acid reflux is still controversial. Here, we describe laparoscopic ligamentum teres cardiopexy, a surgical technique that reinforces the lower esophageal sphincter and restores its competence with a new valve, in patients with the previous conversion of gastric bypass to sleeve gastrectomy and hiatal hernia repair. We present the surgical technique performed on a patient with initial gastric bypass who underwent sleeve gastrectomy for hypoglycemia and hiatoplasty for severe GERD. Persistent GERD requested to undergo ligamentum teres cardiopexy. Ligamentum teres cardiopexy combined with the closure of the gastric crus is a late alternative treatment for GERD in patients with previous sleeve gastrectomy and hiatal hernia.
- Primary hepatic perivascular epithelioid cell tumors: imaging findings with histopathological correlation. [Journal Article]
- CICancer Imaging 2019 Jun 06; 19(1):32
- CONCLUSIONS: On CT, MRI and ultrasound images, most hepatic PEComas are well-defined, heterogeneous, arterial enhanced masses with dysmorphic vessels, with or without fat, especially in middle-aged females. With the potential to be malignant, timely surgical resection and long-term follow-up may be helpful for improving the prognosis.

- Double Versus Single Tendon Transfers to Improve Shoulder Function in Brachial Plexus Birth Palsy. [Journal Article]
- JPJ Pediatr Orthop 2019; 39(6):328-334
- CONCLUSIONS: Both cLT or iTM transfer are effective at augmenting shoulder external rotation in children with C5-C6 BPBP. Furthermore, cLT transfers may yield a larger improvement in external rotation in certain patients. However, both techniques slightly decrease shoulder internal rotation. Given that more total cLT patients lost midline function among matched cohorts, iTM transfer may still be considered when limited midline function is a concern.
