Branching Ratio Method for Assessing Optically Thin Conditions in Laser-Induced Plasmas.

The branching ratio method is usually used to evaluate the optical thinness conditions in laser-generated plasmas, which are important for the application of analytical methods such calibration free laser induced breakdown spectroscopy (CF-LIBS). In this communication, we warn on the possibility that in some circumstances, the branching-ratio method might give results close to the one characterizing optically thin plasma conditions, even in the presence of a substantial self-absorption for the transitions considered.

Mandibular traumas by gunshot. A systematic review with meta-analysis and algorithm of treatment.

The treatment of mandibular fractures by gunshot ranges from late conservative repair to more aggressive early repair in a single stage. Treatments that preserve bony architecture as much as possible should be used, minimising patient morbidity and the complexity of future surgeries. The purpose of this study was to use a systematic review to determine which method of treatment was most effective for mandibular fractures by gunshot.

Recreational training improves cardiovascular adaptations, metabolic profile and mental health of elderly women with type-2 diabetes mellitus.

We investigated the effects of a recreational training (RET) protocol in elderly women with type-2 diabetes mellitus (T2DM). We hypothesized that non-conventional physical activities of RET protocol might improve clinical outcomes regarding cardiovascular function, metabolic profile and mental health as participants keep the adherence to the protocol during the 3-month follow-up. Cardiovascular parameters (heart rate, systolic and diastolic blood pressure), circulating biomarkers (glucose and lipids) and salivary cortisol were attenuated in response to exercise.

Treatment of comminutive fractures by firearm projectiles with adapted wrist external fixator.

Introduction: Facial and mandibular aggression with gunshot wound (GSW) is highly complex and represents a challenge for the assistant surgical team because in addition to the inherent lethal potential, they have the capacity for destruction and mutilation caused by the high kinetic energy conferred to the firearm projectile. Among these lesions, comminutive mandibular fractures are difficult to treat because the anatomical planes are distorted, soft tissues are in severe disarrangement, and bone fragments are without periosteum, which, if opted for an open treatment, with internal fixation, favor the development of soft tissue infections, osteomyelitis, and suture dehiscence. The treatment of comminuted mandibular fractures with external fixator, widely used during the Second World War, represents a modality of treatment that minimizes the risks of failure, since it allows stabilization of the fractured mandible with minimal aggression to the soft tissues.

Surgical Treatment of Posttraumatic Ophthalmoplegia Through the Reconstruction of the Lateral Orbital Wall.

Orbital fractures are injuries frequently related to traumas of the midface. These fractures can be associated with ocular lesions, ranging from small abrasions on the cornea to serious complications such as hyphema and ocular globe rupture. Diplopia and ophthalmoplegia are common findings in orbital fractures.

Antitumor Properties of the leaf essential oil of Zornia brasiliensis.

Zornia brasiliensis, popularly known as "urinária", "urinana", and "carrapicho", is a medicinal plant used in Brazilian northeast folk medicine as a diuretic and against venereal diseases. The aim of this study was to investigate the chemical composition and antitumor potential of the leaf essential oil of Z. brasiliensis.

ent-Kaurane diterpenes from the stem bark of Annona vepretorum (Annonaceae) and cytotoxic evaluation.

This work describes a novel ent-kaurane diterpene, ent-3β-hydroxy-kaur-16-en-19-al along with five known ent-kaurane diterpenes, ent-3β,19-dihydroxy-kaur-16-eno, ent-3β-hydroxy-kaur-16-eno, ent-3β-acetoxy-kaur-16-eno, ent-3β-hydroxy-kaurenoic acid and kaurenoic acid, as well as caryophyllene oxide, humulene epoxide II, β-sitosterol, stigmasterol and campesterol from the stem bark of Annona vepretorum Mart. (Annonaceae). Cytotoxic activities towards tumor B16-F10, HepG2, K562 and HL60 and non-tumor PBMC cell lines were evaluated for ent-kaurane diterpenes.

Antinociceptive and anti-inflammatory effects of electroacupuncture on experimental arthritis of the rat temporomandibular joint.

This study investigated the antinociceptive and anti-inflammatory effects of electroacupuncture (EA) on zymosan-induced acute arthritis of the rat temporomandibular joint (TMJ). Male Wistar rats were injected with saline or zymosan (control group; 2 mg) into the left TMJ. Low frequency EA (10 Hz, 30 min) was performed at acupoints (LI4, LI11, ST36, ST44) or sham points 2 h after or 1 h before zymosan administration.
