Ancient genomics support deep divergence between Eastern and Western Mediterranean Indo-European languages.

The Indo-European languages are among the most widely spoken in the world, yet their early diversification remains contentious. It is widely accepted that the spread of this language family across Europe from the 5th millennium BP correlates with the expansion and diversification of steppe-related genetic ancestry from the onset of the Bronze Age. However, multiple steppe-derived populations co-existed in Europe during this period, and it remains unclear how these populations diverged and which provided the demographic channels for the ancestral forms of the Italic, Celtic, Greek, and Armenian languages.

Herbs carbonization and activation for fast sorption of nitrate ions: a new challenge for a full treatment of groundwater pollution.

The evolution of low-cost ecotechnologies in water treatment and purification is highly increased. Face to the growing global demand for eco-friendly water treatment materials, the non-valorized herb-based biomass covering a large area could be a promising alternative. Herbs (HB) are currently one of the cheapest biomasses.

Mixed Oxides Issued from Hydrotalcite Precursors for Toluene and CO Total Oxidation: Comparison of Preparation Method.

Catalytic total oxidation is an effective technique for the treatment of industrial VOCs. This emission is generally accompanied by the presence of other products like CO, NO or other VOC. In this paper, the development of catalysts for the total oxidation of CO and toluene mixture is performed.

Swan-Ganz catheter induced pulmonary artery perforation during cardiac surgery concerning two cases.

Two case reports describing patients having cardiac operations under extra corporeal circulation are presented. At the completion of the operation, a massive hemoptysis occurred in both patients after a Swan-Ganz catheter had perforated the pulmonary artery. A hemostasis lobectomy was then immediately required.

Acute limb ischemia and heparin-induced thrombocytopenia: the value of echocardiography in eliminating a cardiac source of arterial emboli.

We report an unusual thromboembolic event occurring during severe heparin-induced thrombocytopenia. A left intraventricular thrombus was diagnosed as the source of multiple arterial emboli, resulting in an initial cerebrovascular event and subsequent bilateral acute lower extremity ischemia requiring emergency surgery. No underlying heart disease was detected.

[Ehlers-Danlos type IV syndrome presenting as renovascular hypertension].

The association of Ehlers-Danlos type IV syndrome and acrogeria with renovascular hypertension is reported. Ultrastructural abnormalities observed in our case were different of those associated with acrogeria. We propose that acrogeria associated with Ehlers-Danlos type IV syndrome be a different disease of acrogeria of Gottron.

[Isolated iliac aneurysms. Sixty-seven cases in forty-eight patients].

77 pure iliac aneurysms where detected in a group of 48 patients along a period of 21 years, and represented 12.3% of all patients having aortic, iliac, or aorto-iliac aneurysms. The study group comprised 42 men and 6 women, 48-86 years old (mean 67.

[Acute dissection of the infrarenal aorta and horseshoe kidney. Apropos of a case and review of the literature].

We report about one case of acute dissection of the infrarenal abdominal aorta associated with a horseshoe kidney. A few points in the history of this 47-year-old patient deserve being underscored: the absence of an "etiological" factor of aortic dissection, the presence of five renal arteries, illustrating the complex vascularity of a horseshoe kidney, the specific surgical problems arising from both a lesion of the aortic junction and a horseshoe kidney. On the basis of the literature, we underline the incidence of dissection of the infrarenal aorta (1 to 3%), that of horseshoe kidney (0.

[Necrotizing fasciitis: a medical and surgical emergency. Apropos of a case].

We report about a 66-years-old obese and diabetic female patient, treated with anti-inflammatories for osteoarthritis of the hip and operated for varices of the lower limbs by a bilateral stripping of the internal saphenous veins, who presented with a mortal necrotizing fasciitis during the postoperative period. Necrotizing fasciitis is a severe, infrequent disease jeopardizing the vital prognosis, in which an appropriate and early treatment (medical, using antibiotics, and surgical by extensive debridement) can prevent a fatal outcome. The most often involved germs are streptococci (45%).

[Bacterial endocarditis complicated by popliteal and mesenteric aneurysms].

The authors report about one case of bacterial endocarditis complicated by fungal aneurysms in a superior mesenteric and a popliteal site. While the diagnosis was easy for the popliteal aneurysm, it was not so for the mesenteric aneurysm. Arteriography must have wide indications.

[Mechanical circulatory assistance after coronary surgery in patients over 70 years of age].

Four patients aged over 70 received mechanical circulatory assistance for a period of 2 to 48 hours after myocardial revascularisation surgery. Three patients survived. The simplicity and modest cost of the method encourage the authors to use such assistance whenever necessary.

[Surgical treatment of pulmonary metastases].

Between 1977 and 1986, 23 patients with pulmonary metastases were operated upon in a thoracic and cardiovascular surgery department, totalling 26 thoracotomies. The time elapsed between treatment of the primary tumour and that of the metastasis (single or multiple) ranged from 11 to 89 months. The metastases were discovered on follow-up x-ray films of the chest in 15 cases.

[Post-pneumonectomy bronchial fistula. Treatment by resection of the carina].

A technique for the surgical treatment of bronchial fistulae developed after pneumonectomy is presented. This technique, which resembles that of Abruzzini, consists of resection of the carina followed by tracheo-bronchial suture in a healthy area away from any purulent focus of infection. It is easy to perform and facilitates the treatment of thoracic empyema which is no longer maintained by the fistula.
