1. O laser de baixa potência seria terapêutico para lesões causadas por acidentes ofídicos do gênero Bothrops?
Ainda não há evidências científicas em humanos, entretanto, em caráter experimental e de pesquisa, a laserterapia tem sido usada em lesões necróticas incapacitantes secundárias à picada por serpente na região amazônica, devido seu importante impacto em saúde pública pela retirada precoce do trabalhador na geração de renda. Assim, os benefí

2. Purification and enzymatic characterization of a novel metalloprotease from Lachesis muta rhombeata snake venom
Abstract Background: Lachesis muta rhombeata (Lmr) is the largest venomous snake in Latin America and its venom contains mainly enzymatic components, such as serine and metalloproteases, L-amino acid oxidase and phospholipases A2. Metalloproteases comprise a large group of zinc-dependent proteases that cleave basement membrane components such as fibronectin

3. Adhesion and invasion of Clostridium perfringens type A into epithelial cells
ABSTRACT Clostridium perfringens is the causative agent for necrotic enteritis. It secretes the major virulence factors, and α- and NetB-toxins that are responsible for intestinal lesions. The TpeL toxin affects cell morphology by producing myonecrosis, but its role in the pathogenesis of necrotic enteritis is unclear. In this study, the presence of netB an

4. Rattlesnake Crotalus molossus nigrescens venom induces oxidative stress on human erythrocytes
Abstract Background Globally, snake envenomation is a well-known cause of death and morbidity. In many cases of snakebite, myonecrosis, dermonecrosis, hemorrhage and neurotoxicity are present. Some of these symptoms may be provoked by the envenomation itself, but others are secondary effects of the produced oxidative stress that enhances the damage produce

5. Low-intensity laser therapy improves tetanic contractions in mouse anterior tibialis muscle injected with Bothrops jararaca snake venom
Abstract Introduction Envenomation by Bothrops snakes can produce local pain, edema, hemorrhage and myonecrosis. However, standard antivenom therapy is generally ineffective in neutralizing these effects so that alternative methods of treatment have been investigated. In experimental animals, low-level laser therapy (LLLT) attenuates the local effects of Bo

6. Performance and immunological resistance of Litopenaeus vannamei fed a β-1,3/1,6-glucan-supplemented diet after per os challenge with the Infectious myonecrosis virus (IMNV)
This study determined the efficacy of a β-1,3/1,6-glucan source on the survival, growth, and immunological responses of Litopenaeus vannamei challenged with infectious myonecrosis virus (IMNV). The work was conducted in 20 tanks of 500 L with clear water with constant recirculation and aeration. Shrimp weighing 2.6±0.4 g were stocked at 100 animals/m2 and

7. Acute myonecrosis in horse caused by Clostridium novyi type A
The objective of this study was to describe the first report involving a case of equine acute myonecrosis caused by C. novyi type A with an emphasis on clinical signs, the pathological and bacteriological analysis, and molecular identification of the microorganisms as the key of the definitive diagnosis.

8. Identification of two novel cytolysins from the hydrozoan Olindias sambaquiensis (Cnidaria)
Background : Although the hydrozoan Olindias sambaquiensis is the most common jellyfish associated with human envenomation in southeastern and southern Brazil, information about the composition of its venom is rare. Thus, the present study aimed to analyze pharmacological aspects of O. sambaquiensis venom as well as clinical manifestations observed in affec

9. Evaluation of rat plasma proteins after bothropic venom inoculation and treatment with Mesenquimal stem cells
The aim of this work was to evaluate the mesenchymal stem cells treatment of rats with myonecrosis caused by Rhinocerophis alternatus venom through acute phase proteins (APP) profile. The animals were distributed into three experimental groups (G1, G2 and G3). G1 and G2 were inoculated with 120 μg of R. alternatus venom diluted in 200 µL of ultra-pure wate

10. Mecanismos de proteção da distrofia muscular : estudo proteômico e terapia farmacológica / Protective mechanisms of muscular dystrophy : proteomic study and pharmacological therapy
In Duchenne Muscular Dystrophy (DMD) and in the mdx mice model of DMD, the lack of dystrophin leads to muscle degeneration. The pathogenesis of DMD is related to sarcolemmal fragility, mechanical stress and increased influx of calcium in muscle fibers, due to dysfunction of ion channels, such as the stretch-activated calcium channels. The knowledge of the pr

11. Efeito do ômega-3 em músculos de animais distróficos da linhagem mdx / Effect of omega-3 in dystrophic muscle of mdx mice
In Duchenne muscular dystrophy (DMD) and in the mdx mice model of DMD, absence of dystrophin promotes instability of the sarcolemma and progressive muscle degeneration. The inflammatory process contributes significantly to the pathophysiology of the disease. Anti-inflammatory steroids are widely used for DMD therapy. However, due to its ineffective action an

12. General characterization of venom from the Moroccan snakes Macrovipera mauritanica and Cerastes cerastes
Ophidian envenomation accidents constitute a serious public health problem in many countries around the globe. Over 5 million such accident cases occur each year causing more than 100,000 deaths. In Africa, more than 20,000 deaths per year are registered while 400,000 envenomation victims retain severe and permanent functional sequelae. In Morocco, snakebite
