Resistance of Primary Photosynthesis to Photoinhibition in Antarctic Lichen : Photoprotective Mechanisms Activated during a Short Period of High Light Stress.

The Antarctic lichen, , in its hydrated state has several physiological mechanisms to cope with high light effects on the photosynthetic processes of its photobionts. We aim to investigate the changes in primary photochemical processes of photosystem II in response to a short-term photoinhibitory treatment. Several chlorophyll fluorescence techniques: (1) slow Kautsky kinetics supplemented with quenching mechanism analysis; (2) light response curves of photosynthetic electron transport (ETR); and (3) response curves of non-photochemical quenching (NPQ) were used in order to evaluate the phenomenon of photoinhibition of photosynthesis and its consequent recovery.

Characterisation of α-chitin extracted from a lichenised fungus species Xanthoria parietina.

Lichens are symbiotic associations formed mainly by ascomycete fungi and green algae or cyanobacteria. The presence of chitin in the fungal cell wall has been revealed by previous studies. Considering the presence of fungi in the lichens, this work determines the presence of chitin in a cosmopolitan lichen species Xanthoria parietina.

Mid-term results of the elastic intramedullary nailing in paediatric long bone shaft fractures: a prospective study of 102 cases.

Intrapelvic pin migration after Salter innominate osteotomy and laparoscopic removal: a case report.

Although there are many methods for the treatment of developmental dysplasia of the hip, Salter innominate osteotomy is a surgical technique presently used successfully worldwide. However, several complications can be found after Salter innominate osteotomy. Kirschner (K) wire migration into the pelvic cavity is not a common occurrence and is also rarely reported in the literature.

Closed reduction and fixation of locked symphysis pubis using tubular external fixator: a case report.

Locked symphysis pubis is a kind of pelvic injury in which one pubic bone is jammed in the back of the other or opposite the obturator foramen following lateral compression forces. In this article, we present a 31-year-old female case of locked symphysis pubis which was treated by closed reduction using tubular external fixator. We believe that tubular external fixators are useful devices to perform closed reduction maneuvers for locked pelvic injuries and also help to reduce the need for open reduction and internal implant usage.

Congenital total absence of the quadriceps muscle and patella: a case report with computed tomography scan and three-dimensional reconstructions.

In this study, we present three-dimensional computed tomography (CT) scan image findings of a case with congenital total absence of the quadriceps muscle and patella and partial absence of the sartorius muscle, which caused fixed flexion contracture of the knee joint. Physical examination, radiography, three-dimensional CT scan, and chromosome analysis of the patient were done. On physical examination, the knee joint was at 85 degree fixed flexion contracture.

An unusual initial presentation of Proteus syndrome: macrosyndactyly.

Proteus syndrome is a complex disorder characterized by a wide variety of deformities including macrodactyly. In the present report, we present a case with complex macrosyndactyly in his hand. The patient was surgically treated.
