Sulfide mineral precipitation occurs at mid-ocean ridge (MOR) spreading centers, both in the form of plume particles and seafloor massive sulfide structures. A common constituent of MOR is the iron-bearing sulfide mineral pyrrhotite, which was chosen as a substrate for in-situ incubation studies in shallow waters of Catalina Island, CA to investigate the colonization of iron-oxidizing bacteria. Microbial community datasets were obtained from in-situ incubated pyrrhotite, allowing for direct comparison to microbial communities of iron-sulfides from active and inactive chimneys in deep-sea environments...

The chimney graft (CG) technique can be a useful alternative in treating aortic aneurysms with challenging anatomy, regarding the proximal sealing zone. We describe the case of a patient who developed a type Ia endoleak after chimney endovascular aneurysm repair for a juxtarenal AAA and underwent a proximal CG reconfiguration and implantation of an aortic cuff. The crossing configuration of the CGs should be avoided as it may compromise the circumferential apposition of the endograft and impede the thrombosis of the perigraft gutters...

Left subclavian artery (LSA) revascularization is recommended during elective thoracic endovascular aortic aneurysm repair (TEVAR) when coverage is required for adequate proximal seal. Reported method for LSA revascularization includes open bypass, covered stent placement using chimney technique, and in situ laser fenestration. We reported a novel technique using percutaneous Outback reentry device for LSA revascularization in a 68-year-old male patient who underwent TEVAR for a 9-cm thoracic aortic aneurysm...

Hostile infrarenal aortic neck anatomy presents a challenge for the endovascular treatment of abdominal aortic aneurysm. Open surgical repair has been seen as the gold standard treatment for juxtarenal abdominal aortic aneurysm; however, endovascular techniques are now becoming more prevalent, particularly in patients deemed high risk for morbidity and mortality with open repair. The morphology of an aneurysm is a determinant of long-term outcomes, and short aneurysm necks are associated with poorer outcomes and a higher rate of secondary reinterventions...

Endovascular repair of abdominal aortic aneurysms (EVAR) is now an established treatment modality for suitable patients presenting with aneurysm rupture. EVAR for ruptured aneurysms reduces transfusion, mechanical ventilation, intensive care. and hospital stay when compared with open surgery. In the emergency setting, however, EVAR is limited by low applicability due to adverse clinical or anatomical characteristics and increased need for reintervention. In addition, ongoing bleeding from aortic side branches post-EVAR can cause hemodynamic instability, larger hematomas, and abdominal compartment syndrome...

BACKGROUND: The chimney technique has been successfully used to treat juxtarenal aortic aneurysms. The two main issues with this technique are gutter formation and chimney graft (CG) compression, which induce a risk for type Ia endoleaks and stent thrombosis, respectively. In this benchtop study, the geometry and renal artery flow of chimney endovascular aneurysm repair configurations were compared with chimney configurations with endovascular aneurysm sealing (ch-EVAS). METHODS: Seven flow phantoms were constructed, including one control and six chimney endovascular aneurysm repair (Endurant [Medtronic Inc, Minneapolis, Minn] and AFX [Endologix Inc, Irvine, Calif]) or ch-EVAS (Nellix, Endologix) configurations, combined with either balloon-expandable or self-expanding CGs with an intended higher positioning of the right CG in comparison to the left CG...

Volatile organic compounds (VOCs) emissions from the chimney of a prevailing domestic stove fuelled with raw bituminous coal were measured under flaming and smoldering combustion processes in a farmer's house. The results indicated that the concentrations of VOCs quickly increased after the coal loading and achieved their peak values in a few minutes. The peak concentrations of the VOCs under the smoldering combustion process were significantly higher than those under the flaming combustion process. Alkanes accounted for the largest proportion (43...

We present analytical and numerical results on localized fluidization within a granular layer subjected to a local injection of fluid. As the injection rate increases the three different regimes previously reported in the literature are recovered: homogeneous expansion of the bed, fluidized cavity in which fluidization starts developing above the injection area, and finally the chimney of fluidized grains when the fluidization zone reaches the free surface. The analytical approach is at the continuum scale, based on Darcy's law and Therzaghi's effective stress principle...

Memoirs written by Holocaust survivors and (in some cases) their testimonies retain a salience unmatched by other historical sources. This article discusses one such memoir, Olga Lengyel's Five Chimneys, alongside her 1998 testimony, aiming to engage with broader methodological issues relating to the history of the Holocaust, particularly those about memory, narrative and textuality. Through a detailed discussion of certain moments shaping Olga Lengyel's personal experience, both pre-and post-arrival in Auschwitz, the article captures the tensions and contradictions characterizing the harrowing story of one woman's loss of family in the Holocaust...

The goal of the study was to investigate the effects of drugs modifying L-arginine:NO:cGMP pathway on the development of tolerance to flunitrazepam (FNZ)-induced motor impairment in mice. FNZ-induced motor incoordination was assessed on the 1st and 8th days of experiment, using the rotarod and chimney tests. It was found that (a) both a non-selective nitric oxide synthase (NOS) inhibitor: N (G)-nitro-L-arginine methyl ester (L-NAME) and an unselective neuronal NOS inhibitor: 7-nitroindazole (7-NI) inhibited the development of tolerance to the motor-impairing effects of FNZ in the rotarod and the chimney tests and (b) both a NO precursor: L-arginine and a selective inhibitor of phosphodiesterase 5 (PDE5): sildenafil did not affect the development of tolerance to FNZ-induced motor impairment in mice...

Endovascular aneurysm repair (EVAR) actually represents the treatment of choice for most patients affected by abdominal aortic aneurysm (AAA). However, the feasibility of EVAR depends on anatomical characteristics of abdominal aorta and iliofemoral axis. We present the case of an 82-year-old man affected by severe left hydronephrosis, kidney tumor, and ureteral tumor requiring nephrectomy, who also presented a very voluminous AAA with a large diameter (96 mm), and a large proximal neck (39 mm) with severe angulation of the proximal neck (>60°)...

Aortic arch aneurysm is a complex pathology which requires coverage of one or more aortic arch vessels. In this study we explore the hemodynamic behavior of the aortic arch in aneurysmatic and treated cases with three currently available treatment approaches: Surgery Graft, hybrid Stent-Graft and chimney Stent Graft. The analysis included four models of the time-dependent fluid domains of aneurysmatic arch and of the surgery, hybrid and chimney endovascular techniques. Dimensions of the models are based on typical anatomy, and boundary conditions are based on typical physiological flow...
