Antivenomic approach of different Crotalus durissus collilineatus venoms J. Venom. Anim. Toxins incl. Trop. Dis.
Oliveira,Isadora Sousa de; Pucca,Manuela Berto; Sampaio,Suely Vilela; Arantes,Eliane Candiani.
Abstract Background: Our group has previously performed a proteomic study verifying that individual variations can occur among Crotalus durissus collilineatus venoms. These variations may lead to differences in venom toxicity and may result in lack of neutralization of some components by antivenom. In this way, this study aimed to evaluate the Brazilian anticrotalic serum capacity in recognizing twenty-two Crotalus durissus collilineatus venoms, as well as their fractions. Methods: The indirect enzyme-linked immunosorbent assay (ELISA) was chosen to evaluate the efficacy of heterologous anticrotalic serum produced by Instituto Butantan (Brazil) in recognizing the twenty-two Crotalus durissus collilineatus venoms and the pool of them. Moreover, the venom...

Tityus serrulatus envenoming in non-obese diabetic mice: a risk factor for severity J. Venom. Anim. Toxins incl. Trop. Dis.
Oliveira,Guilherme Honda de; Cerni,Felipe Augusto; Cardoso,Iara Aimê; Arantes,Eliane Candiani; Pucca,Manuela Berto.
Abstract Background In Brazil, accidents with venomous animals are considered a public health problem. Tityus serrulatus (Ts), popularly known as the yellow scorpion, is most frequently responsible for the severe accidents in the country. Ts envenoming can cause several signs and symptoms classified according to their clinical manifestations as mild, moderate or severe. Furthermore, the victims usually present biochemical alterations, including hyperglycemia. Nevertheless, Ts envenoming and its induced hyperglycemia were never studied or documented in a patient with diabetes mellitus (DM). Therefore, this is the first study to evaluate the glycemia during Ts envenoming using a diabetic animal model (NOD, non-obese diabetic). Methods Female mice (BALB/c...

Therapeutic monoclonal antibodies: scFv patents as a marker of a new class of potential biopharmaceuticals BJPS
Pucca,Manuela Berto; Bertolini,Thaís Barboza; Barbosa,José Elpidio; Galina,Simone Vasconcelos Ribeiro; Porto,Geciane Silveira.
Monoclonal antibodies represent the fastest growing class of biopharmaceutical products and have a host of applications in medical research, diagnosis, therapy, and basic science. The production of recombinant monoclonal antibodies has revolutionized the generation of immunoglobulins, and their use represents a strategic breakthrough, affecting the global pharmaceutical market for therapeutic proteins. In the present work, a review of scFv, and the number of related patents, has been carried out. The results show that several countries have scFv patents, most notably the United States, China and United Kingdom. The target of these scFv antibodies was also assessed and the results demonstrate that most are directed toward cancer therapy.
