Purpose: Scapulothoracic bursitis is a painful condition of the scapulothoracic articulation, which may be caused by various pathological anatomical associations. We have arthroscopically observed a constant bare area of bone on the costal scapula surface in patients with scapulothoracic bursitis, contradictory to traditional anatomical reports of scapular muscle relations. We undertook a cadaveric study to further define this anatomical feature.
Methods: Twelve cadaveric shoulders were dissected. The costal surface of the scapula was systematically examined for the presence of a superomedial bare area in each shoulder by three independent clinicians, with dimensions measured using digital calipers.
Results: In all shoulders, there was a clearly defined bare area of bone on the superomedial aspect of the costal surface of the scapula between the serratus anterior insertion and subscapularis origin. The bare area was typically crescenteric in shape, with variable length (mean 22.3 ± 6.0 mm) and width (10.8 ± 2.8 mm). The bare area length (p = 0.043) and width (p = 0.033) were significantly greater in female shoulders compared to male shoulders.
Conclusions: We have established the presence of the superomedial bare area of the costal scapula surface. With an absence of overlying subscapularis muscle, this bare area carries the potential for scapulothoracic impingement, and should be considered as a possible aetiological factor in all patients presenting with scapulothoracic bursitis.

Background: DeBakey type I aortic dissections (AD) are most frequently treated with hemiarch repair. A subset of patients demonstrates persistent distal end-organ ischemia secondary to persistent true lumen (TL) compression. We describe the use of bare metal stent grafting across the residual arch dissection with the Zenith Dissection Endovascular Stent (ZDES, Cook Medical) in 7 patients with type I AD that was repaired in a hemiarch configuration with a compromised distal TL and organ malperfusion.

The land use transition plays an important role for terrestrial environmental services, which had a mixed impact of positive and negative on the groundwater and terrestrial water resource. The health of ecological systems and groundwater depends on the mapping and management of land use. The Ganga basin is one of the most densely populated and agriculture-intensive river systems in the South Asia and the world.

The successful development of a metal-organic framework (MOF)-derived Co/CoO/C core-shell composite integrated into laser-induced graphitic (LIG) carbon electrodes for electrochemical sensing is reported. The sensors are fabricated via a direct laser scribing technique using a UV laser (355 nm wavelength) to induce the photothermolysis of rationally selected ZIF-67 into the LIG matrix. Electrochemical characterization reveals that the incorporation of the laser-scribed ZIF-67-derived composite on the electrode surface reduces the impedance more than 100 times compared with bare LIG sensors.

Assessment of the Impacts of Anthropogenic Activities on Woody Plant Diversity in the Woodlands of the Pette Subdivision (Far-North, Cameroon).

The land use/land cover in the Sudano-Sahelian area of Cameroon has been disturbed since these 3 decades resulting from the influence of anthropogenic factors. This study aimed to assess floristic diversity and the impacts of anthropogenic activities on the Pette forest massifs in the Pette Subdivision. The transect method (1000 × 20 m) was used for plant inventory, and Landsat images 5 TM (1990), 7 ETM+ (2005) and 8 OLI_TIRS (2020) were analysed to determine land cover.
