Joostella strains are emerging candidates for biosurfactant production. Here such ability was analyzed for Joostella strain A8 in comparison with Alcanivorax strain A53 and Pseudomonas strain A6, all previously isolated from hydrocarbon enrichment cultures made of polychaete homogenates. In pure cultures Joostella sp. A8 showed the highest stable emulsion percentage（78.33%）, hydrophobicity rate（62.67%）, and an optimal surface tension reduction during growth in mineral medium supplemented with diesel oil（reduction of about 12 mN/m）, thus proving to be highly competitive with Alcanivorax and Pseudomonas strains. During growth in pure culture different level of biodegradation were detected for Alcanivorax strain A53（52.7%）,Pseudomonas strain A6（38.2%） and Joostella strain A8（26.8%）. When growing in consortia,isolates achieved similar abundance values, with the best efficiency that was observed for the Joostella-Pseudomonas co-culture. Gas-chromatographic analysis revealed an increase in the biodegradation efficiency in co-cultures（about 90%）, suggesting that the contemporary action of different bacterial species could improve the process. Results were useful to compare the efficiencies of well-known biosurfactant producers（i.e. Pseudomonas and Alcanivorax representatives） with a still unknown biosurfactant producer, i.e. Joostella, and to confirm them as optimal biosurfactant-producing candidates.

Physiotherapy in Treating Sexual Pain Disorders in Women: A Systematic Review

Importance: A lot of women suffer from sexual disfunctions, which most of the times cause pain and discomfort. Many genito-pelvic pain disorders appear in the form of contractions or pelvic floor muscle tension, which makes any type of penetration (sexual, tampons, gynaecological examination tools) impossible. In this condition, a woman cannot control these muscle contractions and experiences moderate to intense pain. Objectives: To summarise published evidence on efficacy of physiotherapy for treating female sexual pain disorders, ways to evaluate the condition of a patient and to find the correct treatment. Evidence review: A literature search of Cochrane, PubMed, Journal of Sexual Medicine and Urogynecology Journal databases, SciELO, Google Scholar, Wiley Online Library and University of Barcelona Library was conducted. Findings: Physiotherapy techniques are used to strengthen pelvic floor muscles and relieve pain. Kegel exercises improve the symptoms of sexual pain disorders as they deal with weakened muscles. Vaginal cones exercises are used to strengthen the muscles by means of introduction of gradually increasing weights in the vagina. Biofeedback helps to increase muscle awareness and auto-evaluation of performed exercises. Thermotherapy relaxes muscles and increases elasticity of tissues which helps to reduce pain. Electro-stimulation improves the functionality of muscles. Myofascial therapy consists mainly in manual therapy and in liberating painful trigger points. Conclusions: The role of pelvic physiotherapy is to solve the problems related to sexual pain, recovering the pelvic floor by increasing muscle awareness and proprioception, improving muscle relaxation, toning the muscles and increasing the elasticity of the tissues in order to eliminate or reduce pain. Different exercise techniques, biofeedback, manual therapy and insertion techniques, as well as electro-stimulation and thermotherapy are used to achieve positive results.

Physiotherapy as a Way to Maintain Vaginal Health during Menopause

引用

Advances in Sexual Medicine 2017年第2期7卷 97-104页

The majority of women will experience some or most of the menopause symptoms in their life. Thais time in women’s life is associated with a reduction in estrogen levels which leads to physiological changes that affect different organ systems. In the urogenital tract, these changes usually cause vulvar and vaginal atrophy, affecting a vaginal health of women and decreasing their quality of life. Also, there is a reduction in vaginal moisture and loss of tissue elasticity. Besides, other organ systems are involved and they can also negatively impact normal vaginal physiology. These evolutional changes frequently lead to bothersome symptoms that can negatively impact a woman’s vaginal health and the quality of life. The role of pelvic floor physiotherapy is to improve the tone and strength of the muscle fibres in order to achieve the increase of motor units, improve muscle elasticity and to increase the muscle mass which will help to alleviate menopause symptoms.
