Механизм осаждения частиц загрязнений в капиллярных каналах

Несмотря на экономическое значение научные вопросы применения в регенерации отработанных моторных масел процесса фильтрации практически не рассматривались [8]. Существующие модели фильтрации основаны на моделировании фильтрующей среды как массива сферических "коллекторов". Взвешенные в фильтрующей среде частицы перемещаются в пространстве между " коллекторами". В нашем исследовании предполагается, что частицы, взвешенные в фильтрующейся среде, перемещаются через многочисленные капилляры, пронизывающие насквозь фильтрующий материал. Рассмотрены силы, действующих на частицу в капилляре, увлекаемую потоком жидкости. Получены уравнения, описывающие траекторию движения частицы. Определены условия осаждения частицы в капилляре. Получены формулы, определяющие эффективность осаждения частиц в капилляре

Evidence-Based Complementary Medicine in Breast Cancer Therapy

Complementary medicine is currently widely debated by the oncologic community, because the required scientific proof of safety and effectiveness for most of the therapeutic approaches ha s not yet been met with definite results. In the past years, basic research and clinical evaluation of defined complementary therapeutic concepts in oncology have been intensified in an attempt to integrate these procedures into evidence-based medicine. According to definition, scientifically-based therapies of complementary medicine cannot replace the well-studied conventional cancer-destructive therapies such as surgery, chemotherapy, radiotherapy, or hormone therapy. Complementary approaches in oncology that are recommended as an addition to standard cancer-destructive therapies claim to optimize this therapy. A great body of data emerging from scientifically sound clinical trials prove that defined complementary procedures are beneficial for the patients

Influence of Exercise Therapy on Sexual Dysfunction in Prostate Cancer Patients due to Medical Tumor Treatment A systematic review

Background Sexual dysfunction is a distressing side effect of standard therapies in prostate cancer patients. Objective This systematic review provides an actual overview at the influence of exercise therapy on sexual dysfunction due to standard therapies in prostate cancer patients. Method A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The literature search was performed by 2 independent researchers using Medline/Pubmed and PEDro, additionally the reference lists. RCT with ASCO evidence level I were included, if inclusion criteria were fulfilled. Results The publications analyzed included 17 studies with 1175 patients. 11 of those studies document significant improvement of sexual dysfunction. Conclusion Since most of the studies were not comparable, no generalized statement concerning the benefit of exercise therapy to improve sexual dysfunction in prostate cancer patients is possible. Further controlled studies on the impact of exercise training to improve sexual dysfunction in prostate cancer patients are warranted

Large-scale Survey of the Impact of Complementary Medicine on Side-effects of Adjuvant Hormone Therapy in Patients with Breast Cancer

Background/Aim: The present clinical investigation was performed to confirm the benefit of complementary medicine in patients with breast cancer undergoing adjuvant hormone therapy (HT). Patients and Methods: The patients (n=1561) were treated according to international guidelines. All patients suffered from arthralgia and mucosal dryness induced by the adjuvant HT. In order to reduce the side-effects, the patients were complementarily treated with a combination of sodium selenite, proteolytic plant enzymes (bromelaine and papain) and Lens culinaris lectin. On case report formulas, self assessment arthralgia and mucosal dryness were documented before and four weeks after complementary treatment. Validation was carried-out by scoring from 1 (no side-effects/optimal tolerability) to 6 (extreme side-effects/extremely poor tolerability). A total of 1,165 patients suffering from severe side-effects (symptom scores >3) were enrolled in this investigation. Results: Overall, 62.6% of patients (729 out of 1,165) suffering from severe arthralgia and 71.7% of patients (520 out of 725) with severe mucosal dryness significantly benefited from complementary medicine. Mean scores of symptoms declined from 4.83 before treatment to 3.23 after four weeks of treatment for arthralgia and from 4.72 before treatment to 2.99 after four weeks of treatment for mucosal dryness, the primary aims of the present investigation. The reduction of side-effects of HT was statistically significant (p<0.001) after four weeks. Conclusion: This investigation confirms studies suggesting a benefit of complementary treatment with the combination of sodium selenite, proteolytic enzymes and L. culinaris lectin in patients with breast cancer

Complementary Medicine Down-regulates Side-effects of Hormone Therapy in Prostate Cancer Patients

Aim: The present clinical investigation was performed to evaluate the benefits of complementary medicine in prostate cancer patients undergoing hormone therapy (HT). Patients and Methods: Patients (N=93) were treated according to international guidelines. All patients suffered from side-effects induced by the HT. To reduce the side-effects, the patients were complementarily treated with a combination of sodium selenite, proteolytic plant enzymes and Lens culinaris (Lc) lectin. On case report formulas (CRFs), self assessment of defined side-effects of HT (arthralgia, mucosal dryness, bone pain and hot flushes) were documented before (T-0) and on days 25 (T-1) and 50 (T-2) after complementary treatment. Validation was carriedout by scoring from 1 (no side-effects/optimal tolerability) to 6 (extreme side-effects/extremely bad tolerability), however, only patients suffering from severe side-effects (symptom scores >3) were enrolled in this investigation. Results: The severity of side-effects of HT was reduced by complementary treatment with sodium selenite, proteolytic plant enzymes and Lc-lectin. The mean scores of side-effects declined for arthralgia from 4.72 (T-0) to 3.66 (T-1) to 2.76 (T-2), for mucosal dryness from 4.45 (T-0) to 3.65 (T-1) to 2.90 (T-2), for bone pain from 4.74 (T-0) to 3.44 (T-1) to 2.82 (T-2), for hot flushes from 4.97 (T-0) to 3.70 (T-1) to 3.15 (T-2). The reduced severity of the side-effects was statistically significant (p<0.001) for T-1 and T-2, compared to T-0. Conclusion: This investigation demonstrates benefits of indication-based complementary treatment with the combination of sodium selenite, proteolytic plant enzymes and Lc-lectin in prostate cancer patients, e.g. reduction of side-effects of HT
