A new four-pored Linnaeus, 1758 (Amphisbaenia, Amphisbaenidae) from the north of Espinhaço Mountain Range, Brazil.

A new species of is described from the north of Espinhaço Mountain Range, municipality of Caetité, state of Bahia, Brazil. can be distinguished from its congeners by the following combination of characters: (1) snout convex in profile, slightly compressed not keeled; (2) pectoral scales arranged in regular annuli; (3) four precloacal pores; (4) distinct cephalic shields; (5) 185-199 dorsal half-annuli; (6) 13-16 caudal annuli; (7) conspicuous autotomic site between 4-6 caudal annuli; (8) 16-21 dorsal and ventral segments at midbody; (9) 3/3 supralabials; (10) 3/3 infralabials; and (11) smooth and rounded tail tip. The new species is the 71 species of genus with four precloacal pores, and the 22 species from the Caatinga morphoclimatic domain.

DO OLDER PATIENTS "WARN" THAT THEY WILL SUFFER A NEW FRACTURE?

Objective: To evaluate whether patients older than 60 years admitted for fracture treatment had a history of previous fracture, a diagnosis of osteoporosis, or were under treatment for bone fragility.

Methods: Retrospective study including 100 patients older than 60 years with fracture. Fracture location, bone densitometry within the past two years, previous diagnosis and osteoporosis treatment, and previous fracture within the past five years were assessed.

Exploring the Phase-Locking Mechanisms Yielding Delayed and Anticipated Synchronization in Neuronal Circuits.

Synchronization is one of the brain mechanisms allowing the coordination of neuronal activity required in many cognitive tasks. Anticipated Synchronization (AS) is a specific type of out-of-phase synchronization that occurs when two systems are unidirectionally coupled and, consequently, the information is transmitted from the sender to the receiver, but the receiver leads the sender in time. It has been shown that the primate cortex could operate in a regime of AS as part of normal neurocognitive function.

Cerebral toxoplasmosis in patients with acquired immune deficiency syndrome in the neurological emergency department of a tertiary hospital.

Introduction: Cerebral toxoplasmosis is the most common cause of space occupying brain lesion in patients with HIV/AIDS in Brazil. In the post-HAART era, it is responsible for high rates of morbidity and mortality worldwide.

Materials And Methods: This study consists of a case series of 56 patients diagnosed with cerebral toxoplasmosis whose clinical features, brain imaging and cerebrospinal fluid aspects were analyzed.

A new species of Leposternon Wagler, 1824 (Squamata, Amphisbaenia) from northeastern Argentina.

A new species of Leposternon is described from the Humid Chaco biome in Argentina. The species is known only from its type locality, at El Bagual Ecological Reserve, a conservation unit located in the province of Formosa. The new species can be distinguished from all its congeners by the presence of rostral processes in the maxillae and nasals that contact each other on the facial portion of the skull.

Conversion of chemical scrubbers to biotrickling filters for VOCs and H2S treatment at low contact times.

The purpose of this work was to evaluate the technical and economical feasibility of converting three chemical scrubbers in series to biotrickling filters (BTFs) for the simultaneous removal of H2S and volatile organic compounds (VOCs). The conversion of the full-scale scrubbers was based on previous conversion protocols. Conversion mainly required replacing the original carrier material and recycle pumps as well as modifying the controls and operation of the reactors.

Envenomation caused by Rhopalurus amazonicus Lourenço, 1986 (Scorpiones, Buthidae) in Pará State, Brazil.

Scorpions, mainly those belonging to the genus Tityus cause many deaths and injuries in Brazil, with tens of thousands of envenomations notified every year. However, injuries involving other scorpion species are scarcely registered. Among the sixteen species of the genus Rhopalurus, Thorell, 1876, described up to date, nine are found in this country, with only a confirmed case of human envenomation provoked by R.
