    The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference

    Os autores estudam a utilização de medula óssea em camundongos como estimulação da formação de calo ósseo. Foram utilizados dez camundongos adultos machos de linhagem isogênica gioto com peso de aproximadamente 250 gramas, e realizadas falhas ósseas na região distal do fêmur com alternância do lado direito e esquerdo, divididos em grupos A e B, sendo como controle camundongos com falha óssea isolado e com falhas ósseas com medula óssea colhida previamente de cada camundongo. Após análise qualitativa e quantitativa foi observado que o uso do aspirado de medula óssea não leva à estimulação da formação do calo ósseo e não há o aumento de processo inflamatório local.<br>The aim of this study is to analyze the bone marrow employment in rats to stimulate the bone callus formation. Ten adult rats were used, male, isogenic, gioto lineage, approximate weight of 250 grams. Bone failures were produced at femur distal portion, alternating the right and left sides, and they were divided in group A and B. The control was held in rats presenting an isolated bone failure or having their bone marrow previously collected After quantitative and qualitative analysis, it was observed that the bone marrow utilization does not lead to the bone callus formation and there isn't an increase in the local inflammation process

    A osteoartrite é a forma mais prevalente de doença articular. Os agentes físicos como o gelo e o calor podem combater o processo álgico quando corretamente indicados e utilizados. O objetivo deste trabalho foi a comparação de protocolos de tratamento fisioterapêutico, que envolveram o uso de cinesioterapia, crioterapia e ondas curtas, em indivíduos com osteoartrite de joelho. Em um estudo randomizado prospectivo cego foram tratados 25 indivíduos (25 joelhos), de 58 a 78 anos. GRUPO A: cinesioterapia e ondas curtas (n=9). GRUPO B: cinesioterapia e gelo (n=6). GRUPO C: cinesioterapia (grupo controle) (n=9). As variáveis analisadas foram: percepção subjetiva de dor (Borg), qualidade funcional (Lequesne), amplitude de movimento, flexibilidade e força muscular. A dor melhorou significativamente somente no grupo B, com qualidade funcional e flexibilidade positiva em todos grupos. O ganho de amplitude foi semelhante nos grupos B e C. Houve manutenção da força flexora nos grupos A e B e ganho nos indivíduos do grupo C. Na musculatura extensora observou-se ganho de força no grupo B e C e perda no grupo A. O melhor protocolo foi aquele que envolveu a aplicação de gelo e cinesioterapia para analgesia; não houve relação de ganho de amplitude, flexibilidade e força associado a termoterapia.<br>Osteoarthritis is the most prevalent form of joint disease. Physical agents such as ice and heat can fight the pain process, when correctly indicated and used. The objective of this study was to compare physiotherapy protocols involving the use of exercise, cryotherapy and short waves in individuals with knee osteoarthritis. In a prospective randomized study, 25 individuals were treated (25 knees), with ages ranging from 58 to 78 years. GROUP A: exercise and short-waves (n=9). GROUP B: exercise and ice (n=6). GROUP C: exercise alone (control) (n=9). Analyzed variables were: subjective perception of pain (Borg), functional quality (Lequesne), range of motion, flexibility and muscular strength. Pain significantly improved only for group B, with positive functional quality and flexibility in all groups. The improvement in range of motion was similar for groups B and C. Flexion strength was maintained for groups A and B, and strength gain for individuals in group C. In the extensors muscles, strength gain was seen in groups B and C, while strength loss was reported for group A. The best protocol was that one involving cryotherapy and exercises for pain relief. All groups showed improved functional quality; no correlation was found for range of motion gain, flexibility and strength gain associated with thermotherapy
