Scientists have cracked the genetic code of the bloodsucking tsetse fly, prompting hope that the breakthrough will help future efforts to control one of the most devastating livestock diseases in sub-Saharan Africa spread by the insect.



New LLLT protocol to speed up the bone healing process—histometric and immunohistochemical analysis in rat calvarial bone defect
submitted by mgroceo 23 minutes ago - Topic: Health
A new low-level laser therapy (LLLT) protocol is proposed and compared to another previously studied, in animal models, aiming to establish a more practical LLLT protocol. Protocol 1, the same used in other works and based on the clinical LLLT protocol for bone regeneration, consists of punctual transcutaneous applications in the defect region with fluence of 16 J/cm2 every 48 h for 15 days....

Effects of diode laser on direct pulp capping treatment
submitted by mgroceo 23 minutes ago - Topic: Health
At the present time, evidence-based, best practices have yet to be established for maintaining the vitality of teeth by managing caries-associated pulp exposure in permanent teeth. In terms of biomechanical and esthetic considerations, pulp capping has proven to be more effective than root-canal therapy. Given the low success rate of conventional methods, new techniques, such as laser-assisted ...

Thermal effects and morphological aspects of varying Er:YAG laser energy on demineralized dentin removal: an in vitro study
submitted by mgroceo 23 minutes ago - Topic: Health
The aim of this study was to evaluate thermal changes, dentin ablation removal capacity, and morphological aspects of sound and demineralized human dentin surface irradiated with different output energies of an erbium: yttrium-aluminium-garnet (Er:YAG) laser. Eighty sound human tooth specimens were assigned into two groups: demineralized dentin and sound dentin (control group). The dentin group...

Mid-infrared free-electron laser tuned to the amide I band for converting insoluble amyloid-like protein fibrils into the soluble monomeric form
submitted by mgroceo 23 minutes ago - Topic: Health
A mid-infrared free-electron laser (FEL) is operated as a pulsed and linearly polarized laser with tunable wavelengths within infrared region. Although the FEL can ablate soft tissues with minimum collateral damage in surgery, the potential of FEL for dissecting protein aggregates is not fully understood. Protein aggregates such as amyloid fibrils are in some cases involved in serious diseases....



Characterization and Conservation Concerns of Green Turtles (Chelonia mydas) Nesting in Hong Kong, China
submitted by pp92558 24 minutes ago - Topic: Geography
Hong Kong has one of the last remaining nesting populations of endangered green turtles (Chelonia mydas) in southern China. Because nesting individuals are vital to sustain populations, this study characterizes and reports essential baseline information about nesting pattern, postnesting movement, and genetic composition of green turtles nesting in Hong Kong to provide a basis for effective sci...

From the Transantarctic Basin to the Ferrar Large Igneous Province—New palynostratigraphic age constraints for Triassic–Jurassic sedimentation and magmatism in East Antarctica
submitted by girordamx 24 minutes ago - Topic: Geography
We present new palynological data from the Transantarctic Mountains that clarify the timing of sedimentary and magmatic processes in the transition from continental deposition of the Beacon Supergroup to emplacement of the Ferrar Large Igneous Province. Samples were collected from twenty-three Triassic and Jurassic sections in the southern area of north Victoria Land (NVL), East Antarctica. Rec...


Derivation and validation of a quality indicator for 30-day unplanned hospital readmission to evaluate trauma care
submitted by niaraindacreni 29 minutes ago - Topic: Health
Unplanned readmissions represent 20% of all admissions and cost $12 billion annually in the United States. Despite the burden of injuries for the health care system, no quality indicator (QI) based on readmissions is available to evaluate trauma care. The objective of this study was to derive and internally validate a QI for a 30-day unplanned hospital readmission to evaluate trauma care. We pe...

Preinjury ambulatory status is associated with 1-year mortality following lateral compression Type I fractures in the geriatric population older than 80 years
submitted by niaraindacreni 29 minutes ago - Topic: Health
Lateral compression pelvic Type I fractures in the elderly population are most often low-energy osteoporosis related fractures. Previous literature comparing pelvic fractures in young versus elderly patients called into question the general consideration of these injuries as benign injuries with favorable prognoses; however, the geriatric population older than 80 years is often underrepresented...


Levothyroxine therapy before brain death declaration increases the number of solid organ donations
submitted by niaraindacreni 29 minutes ago - Topic: Health
Protocols call for the start of hormonal therapy with levothyroxine after the declaration of brain death. As the hormonal perturbations occur during the process of brain death, the role of the early initiation of levothyroxine therapy (LT) to salvage organs is not well defined. The aim of this study was to evaluate the impact of early LT (before the declaration of brain death) on the number of ...

Retrospective analysis of facial dog bite injuries at a Level I trauma center in the Denver metro area
submitted by niaraindacreni 29 minutes ago - Topic: Health
Facial dog bite injuries pose a significant public health problem. Seventy-five consecutive patients (45 males, 30 females) treated solely by plastic surgery service for facial dog bite injuries at a Level I trauma center in the Denver Metro area between 2006 and 2012 were retrospectively reviewed. The following information were recorded: breed, relationship of patient to dog, location and numb...


External validation of the Blunt Abdominal Trauma in Children (BATiC) score: Ruling out significant abdominal injury in children
submitted by niaraindacreni 29 minutes ago - Topic: Health
The aim of this study was to validate the use of the Blunt Abdominal Trauma in Children (BATiC) score. The BATiC score uses only readily available laboratory parameters, ultrasound results, and results from physical examination and does therefore not carry any risk of additional radiation exposure. Data of pediatric trauma patients admitted to the shock room between 2006 and 2010 were retrospec...

Venovenous extracorporeal life support improves survival in adult trauma patients with acute hypoxemic respiratory failure: A multicenter retrospective cohort study
submitted by niaraindacreni 29 minutes ago - Topic: Health
Venovenous extracorporeal life support (VV ECLS) has been reported in adult trauma patients with severe respiratory failure; however, ECLS is not available in many trauma centers, few trauma surgeons have experience initiating ECLS and managing ECLS patients, and there is currently little evidence supporting its use in severely injured patients. This study seeks to determine if VV ECLS improves...

Pulmonary embolism without deep venous thrombosis: De novo or missed deep venous thrombosis?
submitted by niaraindacreni 29 minutes ago - Topic: Health
Pulmonary embolus (PE) is thought to arise from a deep venous thrombosis (DVT). Recent data suggest that PE can present without DVT, inferring that PE can originate de novo (DNPE). We examined the relationship between DVT and PE in trauma patients screened for DVT with duplex sonography (DS). We sought to validate the incidence of PE without evidence of DVT and to examine the clinical significa...

Guiding the management of intubated patients with pneumonia and ventilator-associated events using serial catheter-directed bronchoalveolar lavage
submitted by niaraindacreni 29 minutes ago - Topic: Health
We evaluated the role of serial catheter-directed bronchoalveolar lavage (CDBAL) in the diagnosis and management of pneumonia in ventilated surgical intensive care unit patients. Intubated surgical intensive care unit patients were prospectively evaluated with serial CDBALs from September 1, 2012, to May 31, 2013. Initial CDBALs were performed if patients developed the following signs of pneumo...
