When canals and harbours are dredged, huge amount of polluted sediments has to be stocked and transported to the landfill with incredibly high costs of management. Among the remediation techniques for the reclamation of polluted sediments and soils, phytoremediation represents a sustainable and effective technique though still not fully promoted or commercialized. In this study we have tested the suitability for plant nursing of a substrate resulting from sediments dredged from a canal and treated with phytoremediation...

Cicadas form intimate symbioses with bacteria to obtain nutrients that are scarce in the xylem fluid they feed on. The obligate symbionts in cicadas are purportedly confined to specialized bacteriomes, but knowledge of bacterial communities associated with cicadas is limited. Bacterial communities in the bacteriomes and organs of reproductive, digestive and excretory systems of two cicada species (Platypleura kaempferi and Meimuna mongolica) were investigated using different methods, and the bacterial diversity and distribution patterns of dominant bacteria in different tissues were compared...

Septoplasty is a frequently performed procedure with mostly minor complications. Nevertheless, it may lead to serious complications.The authors present a 29-year-old patient admitted to their hospital 10 days after septoplasty in another institution. He suffered a total loss of vision immediately after the surgery.High-resolution computed tomography and magnetic resonance imaging revealed a direct trauma of the optic canal and an inflamed and edematous optic nerve. Even though a successful endoscopic optic nerve was performed, the patient's loss of vision did not improve after the surgery...

Extra-skeletal Ewing sarcoma in pregnancy is rare. There is thus limited scientific evidence to guide clinicians in its complicated management, particularly within the context of early gestation. We therefore share our successful outcome in a 32-year-old pregnant patient, following a unique management strategy of complete aggressive surgical resection prior to neo-adjuvant therapy. The case involved a 2-month history of right-sided back and gluteal pain, with associated paraesthesia. Lumbosacral magnetic resonance imaging (MRI) revealed an approximate 40×50 mm indeterminate mass in the lower right paraspinal musculature...

The treatment of fractures in osteopetrosis can be complicated and difficult. We describe the use of an industrial grade tungsten carbide drill bit in the treatment of one of these complex fractures. An industrial grade tungsten carbide drill bit was used to fashion a medullary canal in the surgical treatment of a left peri-implant fracture of the neck of femur in a patient with osteopetrosis. The patient was successfully treated with a hemiarthroplasty with good functional outcomes. A tungsten carbide drill bit serves as an effective and safe option in the treatment of osteopetrotic femoral neck fractures...

BACKGROUND Acute compartment syndrome (ACS) of the thigh after elective primary total knee arthroplasty is rare. If not recognized and treated promptly, devastating consequences may result. Certain regional anesthesia techniques are thought to mask the symptoms of acute compartment syndrome, but there are no cases reported of adductor canal catheters masking the symptoms of thigh compartment syndrome. We report a case where symptoms and diagnosis of acute anterior thigh compartment syndrome were not masked by a functioning adductor canal catheter...

The ultrastructure of male reproductive accessory glands was investigated in the scorpionfly Sinopanorpa tincta (Navás, 1931) (Mecoptera: Panorpidae) using light and transmission electron microscopy. The male accessory glands comprise one pair of mesodermal glands (mesadenia) and six pairs of ectodermal glands (ectadenia). The former opens into the vasa deferentia and the latter into the ejaculatory sac. The mesadenia consist of a mono-layered elongated columnar epithelium, the cells of which are highly microvillated and extrude secretory granules by means of merocrine mechanisms...
