Em continuação as pesquisas que vimos realizando nos Embiídeos é feito um estudo comparado das peças bucais entre machos e fêmeas de Embolyntha batesi. A cabeça é prognata recoberta por diminutas cerdas. É a região mais resistente do inseto, devido proteger, além de outros órgãos, principalmente, o sistema nervoso. Varia de tamanho nos dois sexos com os índices (comprimento : largura) na fêmea de 1,06 e nos machos de 1,36; a cabeça da fêmea é achatada, enquanto que a dos machos é alongada. Quase tôdas as suturas são visíveis nos sexos, com excessão de algumas, como é o caso da coronal e post-frontal dos machos. De tôdas as suturas, a temporal é a mais interessante, limita a região do vertex com as genas, ao mesmo tempo que origina um sulco profundo, que penetra na cápsula craniana fazendo parte do esqueleto interno da cabeça, e sendo responsável pelo aspecto diferente das mesmas. A sutura temporal, na região ventral, separa as genas das subgenas. A sutura hipostomal, em ambos os sexos, é muito acentuada, e na sua parte mais interna, vêm se inserir os ramos posteriores do tentório, e, ainda lateralmente, as maxilas. O tentório é primitivo, tendo um corpo central, de forma quadrangular e, de cada ângulo parte um ramo; dois anteriores, menores, que se dirigem para a região dorsal onde se bifurcam, indo ter próximo á base das antenas e mandíbulas, e dois ramos posteriores que seguem a direção ventral, indo ter á região hipostomal. As antenas são filiformes, variando o número de segmentos. Os olhos dos machos são reniformes, salientes e grandes, enquanto que os das fêmeas são pequenos, ovais e achatados. O número de omatídeos de macho é 34, e, na fêmea é 41, em uma determinada área. O clípeo quase não se diferencia da fronte, porém encontra-se dividido em anti-clípeo e post-clípeo. A sutura do clípeo-labro é bem acentuada, deixando transparecer, após a diafanização do material, um espessamento da cutícula na sua região mais interna, destinada a implantação dos músculos que movimentam o labro. Na parte ventral o labro apresenta sensilas, que variam quanto a forma, tamanho e estrutura nos dois sexos. As mandíbulas apresentam-se muito diferentes devida sua função, isto é, trituradora nas fêmeas e preensora nos machos. Pela simples morfologia das mandíbulas podemos identificar o sexo nos Embiídeos. Em ambos temos dentes incisivos e molares, porém mais acentuados nas fêmeas. Nos machos a região interna da mandíbula tem a forma côncava, com cutícula...

El diagnòstic de la Trombosi Venosa Profunda pot ser difícil degut a una clínica poc específica. S’han desenvolupat diversos algoritmes en què el Dímer-D té un important paper, degut al seu elevat valor predictiu negatiu. El Dímer-D augmenta amb l’edat i disminueix des de l’aparició dels símptomes, si ajustem el seu punt de tall tenint en compte aquests dos paràmetres, és possible augmentar el seu rendiment diagnòstic. Segons els nostres resultats, als subjectes majors de 70 anys i als que presenten una clínica inferior a 14 dies, es podria utilitzar un punt de tall de 1000 ng/mL

Candida glabrata is an opportunistic fungal pathogen that can cause severe invasive infections and can evade phagocytic cell clearance. We are interested in understanding the virulence of this fungal pathogen, in particular its oxidative stress response. Here we investigated C. glabrata, Saccharomyces cerevisiae and Candida albicans responses to two different oxidants: menadione and cumene hydroperoxide (CHP). In log-phase, in the presence of menadione, C. glabrata requires Cta1p (catalase), while in a stationary phase (SP), Cta1p is dispensable. In addition, C. glabrata is less resistant to menadione than C. albicans in SP. The S. cerevisiae laboratory reference strain is less resistant to menadione than C. glabrata and C. albicans; however S. cerevisiaeclinical isolates (CIs) are more resistant than the lab reference strain. Furthermore, S. cerevisiae CIs showed an increased catalase activity. Interestingly, in SP C. glabrata and S. cerevisiae are more resistant to CHP than C. albicans and Cta1p plays no apparent role in detoxifying this oxidant.

The opportunistic fungal pathogen Candida glabrata is the second most common isolate from bloodstream infections worldwide and is naturally less susceptible to the antifungal drug fluconazole than other Candida species. C. glabrata is a haploid yeast that contains three mating-type like loci (MTL), although no sexual cycle has been described. Strains containing both types of mating information at the MTL1 locus are found in clinical isolates, but it is thought that strains containing type a information are more common. Here we investigated if a particular combination of mating type information at each MTLlocus is more prevalent in clinical isolates from hospitalized patients in Mexico and if there is a correlation between mating information and resistance to fluconazole and 5-fluorocytosine. We found that while both types of information at MTL1 are equally represented in a collection of 64 clinical isolates, the vast majority of isolates contain a-type information at MTL2 and α-type at MTL3. We also found no correlation of the particular combination of mating type information at the three MTL loci and resistance to fluconazole.

The purpose of the present paper was to evaluate the effects of an 8-week multimodal program focused on core stability exercises and recovery massage with DVD support for a 6-month period in physical and psychological outcomes in breast cancer survivors. A randomized controlled clinical trial was performed. Seventy-eight (n = 78) breast cancer survivors were assigned to experimental (core stability exercises plus massage-myofascial release) and control (usual health care) groups. The intervention period was 8 weeks. Mood state, fatigue, trunk curl endurance, and leg strength were determined at baseline, after the last treatment session, and at 6 months of followup. Immediately after treatment and at 6 months, fatigue, mood state, trunk curl endurance, and leg strength exhibited greater improvement within the experimental group compared to placebo group. This paper showed that a multimodal program focused on core stability exercises and massage reduced fatigue, tension, depression, and improved vigor and muscle strength after intervention and 6 months after discharge.

AIM To determine the opinions of infectious diseases professionals on the possibilities of monitoring patients with HIV in Primary Care. DESIGN Qualitative study using in-depth interviews. LOCATION Infectious Diseases Unit in the University Hospital "Virgen de la Victoria" in Málaga. PARTICIPANTS Health professionals with more than one year experience working in infectious diseases. A total of 25 respondents: 5 doctors, 15 nurses and 5 nursing assistants. METHOD Convenience sample. Semi-structured interviews were used that were later transcribed verbatim. Content analysis was performed according to the Taylor and Bogdan approach with computer support. Validation of information was made through additional analysis, expert participation, and feedback of part of the results to the participants. RESULTS Hospital care professionals considered the disease-related complexity of HIV, treatment and social aspects that may have an effect on the organizational level of care. Professionals highlighted the benefits of specialized care, although opinions differed between doctors and nurses as regards follow up in Primary Care. Some concerns emerged about the level of training, confidentiality and workload in Primary Care, although they mentioned potential advantages related to accessibility of patients. CONCLUSIONS Physicians perceive difficulties in following up HIV patients in Primary Care, even for those patients with a good control of their disease. Nurses and nursing assistants are more open to this possibility due to the proximity to home and health promotion in Primary Care.

Background. Hamstring injuries continue to affect active individuals and although inadequate muscle extensibility remains a commonly accepted factor, little is known about the most effective method to improve flexibility. Purpose. To determine if an isolated neurodynamic sciatic sliding technique would improve hamstring flexibility to a greater degree than stretching or a placebo intervention in asymptomatic subjects with short hamstring syndrome (SHS). Study Design. Randomized double-blinded controlled trial. Methods. One hundred and twenty subjects with SHS were randomized to 1 of 3 groups: neurodynamic sliding, hamstring stretching, and placebo control. Each subject's dominant leg was measured for straight leg raise (SLR) range of motion (ROM) before and after interventions. Data were analyzed with a 3 × 2 mixed model ANOVA followed by simple main effects analyses. Results. At the end of the study, more ROM was observed in the Neurodynamic and Stretching groups compared to the Control group and more ROM in the Neurodynamic group compared to Stretching group. Conclusion. Findings suggest that a neurodynamic sliding technique will increase hamstring flexibility to a greater degree than static hamstring stretching in healthy subjects with SHS. Clinical Relevance. The use of neurodynamic sliding techniques to improve hamstring flexibility in sports may lead to a decreased incidence in injuries; however, this needs to be formally tested.
