Outcomes were also compared in women with advanced prolapse versus stage II prolapse. RESULTS Success did not differ between groups (ULS 58.2% [57/117] versus SSLF 58.5% [55/113], aOR 1.0 [0.5-1.8]). No differences were detected in individual success components (p > 0.05 for all components). Prolapse symptom severity scores improved in both interventions with no intergroup differences (p = 0.82). Serious adverse events did not differ (ULS 19.7% versus SSLF 16.8%, aOR 1.2 [0.6-2.4]). Success was lower in women with advanced prolapse compared with stage II (58.3% versus 73.2%, aOR 0.5 [0.3-0.9]), with no retreatment in stage II. CONCLUSIONS Surgical success, symptom severity, and overall serious adverse events did not differ between ULS and SSLF in women with advanced prolapse.

This definition tells us that it is a need to void; it does not tell us what triggers it. The aim of this study is to report bladder sensations that wake up women with nocturia (N). Descriptions of sensations in relation to various overactive bladder (OAB) symptoms, most bothersome symptoms, urinary incontinence (UI) and urodynamic findings are examined. MATERIALS AND METHODS A prospective study of women > 18 years old presenting with OAB and nocturia. Data collected included presenting and most bothersome symptoms, descriptions of bladder sensations associated with nocturia, number of frequency and nocturia episodes, nighttime UI and urodynamic findings. RESULTS One hundred fifty women were recruited with mean age 52 years, mean duration of symptoms 10.5 months and mean number of nocturia episodes 4.5. All women reported multiple presenting and bothersome symptoms. Fifty-five per cent had detrusor overactivity (DO). "Multiple" and "more intense" bladder sensation descriptions of nocturia were associated with advanced age, more frequent nighttime UI, when nocturia was considered most bothersome and in the presence of DO. The most frequent single description was "strong desire to void". The most frequently used combination was "strong desire to void, sudden compelling desire to void, bladder pain and full bladder". CONCLUSION Descriptions of bladder sensations associated with nocturia in women with OAB were diverse and overlapping. It is important to report clinically and in research why patients have nocturia as this will have bearing on its treatment.This is the first report of a highly efficient Agrobacterium tumefaciens-mediated transformation protocol for Acanthaceae and its utilization in revealing important roles of cytokinin in regulating heterophylly in Hygrophila difformis. Plants show amazing morphological differences in leaf form in response to changes in the surrounding environment, which is a phenomenon called heterophylly. Previous studies have shown that the aquatic plant Hygrophila difformis (Acanthaceae) is an ideal model for heterophylly study. However, low efficiency and poor reproducibility of genetic transformation restricted H. difformis as a model plant. In this study, we reported successful induction of callus, shoots and the establishment of an efficient stable transformation protocol as mediated by Agrobacterium tumefaciens LBA4404. We found that the highest callus induction efficiency was achieved with 1 mg/L 1-Naphthaleneacetic acid (NAA) and 2 mg/L 6-benzyladenine (6-BA), that efficient shoot induction required 0.1 mg/L NAA and 0.1 mg/L 6-BA and that high transformation efficiency required 100 µM acetosyringone. Due to the importance of phytohormones in the regulation of heterophylly and the inadequate knowledge about the function of cytokinin (CK) in this process, we analyzed the function of CK in the regulation of heterophylly by exogenous CK application and endogenous CK detection. By using our newly developed transformation system to detect CK signals, contents and distribution in H. difformis, we revealed an important role of CK in environmental mediated heterophylly.BACKGROUND Multiple mechanisms of immunosuppression have been identified in the tumor microenvironment including regulatory B cells (Breg). Recently, we have shown that Breg suppress T cell function by production of adenosine (ADO). However, the autocrine effect of ADO on B cells and the role of Breg in head and neck cancer remains unclear. METHODS Blood (n = 42) and tumor tissue (n = 39) of head and neck cancer patients and healthy donors (n = 60) were analyzed by FACS. The effect of ADO on phenotype, intracellular signaling pathways, Ca2+ influx and ADO production was analyzed in Breg and effector B cells (Beff) by FACS, luminescence and mass spectrometry. The blockage of the ADO receptor A2A was analyzed in a murine head and neck cancer model. RESULTS ADO-producing Breg were found in tumor tissue and peripheral blood. TG100-115 mw ADO inhibited the intracellular Bruton's tyrosine kinase (BTK) and Ca2+ influx only in Beff. The inhibition of BTK by ibrutinib mimicked the effect of ADO, and ibrutinib reduced the production of ADO by downregulation of CD39 in vitro. The inhibition of ADO receptor A2A significantly reduced tumor mass and increased B cell infiltration, in vivo. CONCLUSION Our data demonstrate the presence of a novel ADO-producing Breg population within the tumor microenvironment in mice and humans. A new model is proposed on how ADO-producing Breg can influence the function of Beff cells in healthy donors and cancer patients. Thus, the modulation of the ADO pathway in B cells may serve as a therapeutic approach for cancer patients.PURPOSE The failure in timely healing of wounds is a central feature in chronic wounds that leads to physiological, psychological and economic burdens. Macrophages have been demonstrated to have various functions in wounds including host defense, the promotion and resolution of inflammation, the removal of apoptotic cells and tissue restoration following injury. Accumulated evidence suggests that macrophage dysfunction is a component of the pathogenesis of non-healing wounds. While the overall signaling cascades have been well understood, their complex interplay and a detailed characterization of events that are disrupted in chronic wounds have still not emerged satisfactorily. METHODS The existing literature was reviewed to summarize the regulation of macrophage polarization in wound closure and dysregulation in non-healing wounds. Further, the review also underscored the role of Nrf2 in promoting macrophage-mediated regulation in wound responses and in particular, macrophage involvement in iron homeostasis that is impaired in chronic wounds such as in diabetes. RESULTS The mechanisms involved in the reprogramming of macrophage subtypes in chronic wounds are still emerging. Furthermore, treating non-healing wounds has increasingly been shifting focus from generic treatments to the development of targeted therapies. Increasing evidence suggests the need for modeling wound tissue in vitro which may very well serve a critical aspect to characterize the relevant factors that sustain chronic wounds in vivo such as the constant iron overload at the wound site from recurrent infection and bleeding. CONCLUSION The development of targeted therapies and also developing a reliable means to monitor assisted healing of chronic wounds are two major goals to be pursued. In addition, identifying molecular targets that can regulate macrophages to aid tissue restoration in chronic wounds would serve the crucial step in realizing both aforementioned goals.INTRODUCTION There remains disagreement about the use of cemented or uncemented total hip arthroplasty (THA) for patients with a displaced intracapsular femoral neck fracture (FNF). The aim of this study was to assess implant survival, mortality, and postoperative complication rates of uncemented THA for a displaced intracapsular FNF in a single center. PATIENTS AND METHODS A cohort of 115 patients who received uncemented THAs for a displaced intracapsular FNF was retrospectively examined for implant survival in terms of revision and any reoperation, mortality, and postoperative complications. RESULTS The one- and five-year implant survival was 99.1% (95% confidence interval (CI) 97.3-100.9) and 97.8% (95% CI 94.7-100.9) for revision and 93.6% (95% CI 88.9-98.3) and 90.0% (95% CI 83.3-96.7) for any reoperation, respectively. Impaired mobility was significantly associated with lower implant survival (p = 0.01). The one, three, and 12 month mortality rates were 2.8% (95% CI 0-5.9), 3.7% (95% CI 0.2-7.2), and 5.6% (95% CI 1.3-9.9), respectively. Postoperative complication rate was 10% with 5% intra-operative fractures. CONCLUSIONS Contrary to earlier reports of results of uncemented THA for displaced FNF, the results of this study were comparable with those reported in the literature for cemented THA in displaced FNF with respect to implant survival, mortality, and complication rates. This indicates that uncemented THA could be a viable option for these patients. In future, the additional literature with a prospective design is needed to support and reinforce our conclusion.The HtrA protein family represents an important class of serine proteases that are widely distributed across taxa. These evolutionarily conserved proteins are crucial for survival and function as monitors of protein synthesis during various stresses. Here, we performed gene expression analysis of the entire set of putative serine protease genes in Halothece sp. PCC7418 under salt stress conditions. The gene-encoding HtrA2 (H3553) was highly upregulated. This gene was cloned and functionally characterized, and its sub-cellular localization was determined. The recombinant H3553 protein (rH3553) displayed a pH optimum of 8.0, remained stable at 45 °C, and its proteolytic activity was not affected by salts. H3553 completely degraded the unfolded model protein, β-casein. In contrast, the folded model substrates (lysozyme or BSA) were not degraded by rH3553. Denaturation of BSA at a high temperature significantly increased its degradation by rH3553. H3553 was detected in the soluble protein fraction as well as the plasma membrane and thylakoid membrane fractions. Interestingly, the majority of H3553 was present in the plasma membrane under salt and heat stress conditions. Thus, H3553 resides in multiple sub-cellular locations and its localization drastically changes after exposure to stresses. Taken together, H3553 underpins protein quality-control process and is involved in the response and adaptation to salinity and heat stresses.Interactions with mycorrhizal fungi have been increasingly recognized as one of the most important ecological factors determining the distribution and local abundance of orchids. While some orchid species may interact with a variety of fungal associates, others are more specific in their choice of mycorrhizal partners. Moreover, orchids that co-occur at a given site, often associate with different partners, possibly to avoid competition and to allow stable coexistence. However, whether differences in mycorrhizal partners directly affect seed germination and subsequent protocorm formation remains largely unknown. In this research, we used in vitro germination experiments to investigate to what extent seed germination and protocorm formation of Gymnadenia conopsea was affected by the origin and identity of fungal associates. Fungi were isolated from G. conopsea and three other co-occurring orchid species (Dactylorhiza viridis (Coeloglossum viride), Herminium monorchis, and Platanthera chlorantha). In total, eight fungal associates, belonging to Tulasnellaceae, Ceratobasidiaceae, and Serendipitaceae, were successfully isolated and cultured.
