DNA rearrangement rather than point mutation is an emerg ing hypothesis for human carcinogenesis. Although there is no direct evidence for this hypothesis, indirect evidence is pro vided by cancer cytogenetics and genetics. It has been sug gested that patients with Bloom's syndrome, a disorder of spontaneous chromosomal rearrangement, develop the com mon fatal internal cancers and thus that gen...

In the south of France, leishmaniasis due to Leishmania infantum occurs in the following five foci of endemicity (from west to east): Pyrénées-Orientales, Cévennes, Provence, Côte d'Azur, and Corsica. Between 1981 and 2002, 712 Leishmania strains obtained from humans, dogs, cats, and sand flies were studied by isoenzyme analysis. In total, seven zymodemes were identified: MON-1, MON-11, MON-24,...

In this article we present a variant of the basic result of "T. Gnana. Bhaskar and V. Lakshmikanthan, Fixed point theorem in partially ordered metric spaces and applications, Nonlinear Anal. TMA, 65 (2006), 1379–1393." to …nd the coupled …xed points of multivalued mappings without mixed monotone property in cone metric space involving non-normal cones. As applications we prove the existence of ...

Acute scrotal pain makes up approximately 0.5% of all complaints presenting to an emergency department. Some of the most com-mon diagnoses for this complaint are testicular torsion and epididymitis. Misdiagnosing testicular torsion can lead to organ loss,cosmetic deformity, and compromised fertility. Modem ultrasound examination of the scrotum is the test of choice for acute scrotal pathology a...

Despite the importance of sparsity in manybig data applications, there are few existingmethods for efficient distributed optimizationof sparsely-regularized objectives. In thispaper, we present a communication-efficientframework for L1-regularized optimization indistributed environments. By taking a non-traditional view of classical objectives as partof a more ge...

Vascular access for haemodialysis (HD) and other forms of renal replacement therapy where access to blood is required (such as haemofiltration) is a broad area that encompasses a vari‐ ety of specialties including nephrology, intensive care, interventional radiology and surgery. Within the acute setting, vascular access via catheter placement can be performed in an emergency. However, longer-te...

BACKGROUND Maize technologies expressing Bacillus thuringiensis (Bt) insecticidal proteins are widely used in Argentina to control sugarcane borer (Diatraea saccharalis Fabricius). Unexpected D. saccharalis damage was observed to Bt maize events TC1507 (expressing Cry1F) and MON 89034 × MON 88017 (expressing Cry1A.105 and Cry2Ab2) in an isolated area of San Luis Province. Diatraea saccharalis l...

The diagnoses and subsequent treatment of poisoned patients manifesting cardiovascular compromise challenges the most experienced emergency physician. Numerous drugs and chemicals cause cardiac and vascular disorders. Despite widely varying indications for therapeutic use, many agents share a common cardiovascular pharmacologic effect if taken in overdose. Standard advanced cardiac life support...

Almost all the submicron metal particles in the glass coating of breccia 15286 are rounded and Contain two phases, metal and sulfide tEeS). The Ni content of the metal phase as determined by scanning transmission electron microscope X-ray analysis ranged from 9.4 to 15.5 tvt. The sulfide was nearly stoichiometric troilite containing up to 1.3 wt’ Ni. The close chemical and mi crostructural simi...
