Cytoplasmic and nuclear P27Kip1 showed overexpression following treatment with I3C higher than that detected following DIM treatment. This study provides a mechanistic elucidation of the previously reported cell cycle arrest by I3C and DIM in breast cancer cells suggesting that this effect could be through modulation of miRNAs expression that, in turn, regulates the genetic network controlling the G1/S phase in cell cycle progression.Enzymatic hydrolysis of naringin by the action of naringinase is one of the standard practices adopted in the citrus fruit juice industry for debittering. In the present study, a submerged fermentation condition was optimized for producing naringinase from Aspergillus niger van Tieghem MTCC 2425. As per Placket-Burman design, pH (3-5), incubation temperature (26-30 °C), and inducer concentration (12-18 g·L-1) were the most important factors influencing the naringinase production. Naringin from citrus waste was used as an inducer. A rotatable central composite design was employed on these three variables and the numerical optimization predicted that fermentation at 29.8 °C, pH 4.7, and inducer concentration of 14.9 g L-1 would yield a maximum naringinase activity of 545.2 IU g-1. During partial purification, ion exchange chromatography led to a 9.92-fold increase in enzyme activity resulting a specific activity of 5460 IU g-1 with an activity recovery of 17%. As reflected by SDS-PAGE profile, the partially purified naringinase showed the molecular weight bands of 10-20, 65, and 80 kDa, respectively. The purified form of enzyme showed optimum stability at pH 5 and 50 °C. The naringinase activity was completely retained up to 150 days when stored at 4 °C.Cellulases have many useful applications in industry and biotechnology. So, identification of new bacterial strains expressing cellulases with better properties is desired. Five soil bacterial strains screened for high carboxymethyl cellulase (CMCase) activities were characterized and identified by 16S rRNA analysis as Bacillus amyloliquefaciens (FAY088), B. velezensis (FAY0103), B. tequilensis (FAY0117), B. subtilis (FAY0136), and B. subtilis (FAY0182). Their CMCase activities were 1.49, 1.26, 1.21, 1.21, and 1.24 U/ml, respectively. The maximum CMCase production was attained by growth at 35 °C, pH 6, and 180 rpm for 5 days. Residual activities of CMCases from FAY088 and FAY0117 were 88% or more after growth at 40 °C, which is same as FAY0182 CMCase at 40 and 45 °C. Additionally, FAY0182 retained 73% residual activity at 50 °C. FAY088 and FAY0182 retained more than 85% at pH 7 and 8. Conversely, residual activities from FAY0103 and FAY0136 declined a lot by increasing growth temperature beyond 40 °C and pH beyond 7. The maximum CMCase stability in all isolates was observed at pH 7, 3-h incubation, and 40 °C except for FAY0103 CMCase showed optimum temperature at 30 °C. More than 70% CMCase stability was retained in case of FAY088 at 50 °C, FAY0117 at 50-70 °C, and FAY0136 at 50-60 °C. FAY088 CMCase seemed to be the lest sensitive to temperature variation as it displayed residual activities 67, 72, 78, 84, 77, 74, and 72% at pH 3, 4, 5, 6, 8, 9, and 10, respectively. Finally, the five CMCase-producing isolates are recommended further enzyme applications in biotechnology and industry.Clinical research has resulted in an improvement of treatment options for patients with immune thrombocytopenia (ITP) over the last years. However, only few data exist on the real-life management of patients with ITP. To expand the knowledge, a multicenter, national survey was undertaken in 26 hematology practices distributed all over Germany. All patients with a diagnosis of ITP were documented using questionnaires, irrespective of the diagnosis date over a period of 2 years. Overall, data of 1023 patients were evaluated with 56% of patients being older than 60 years. Seventy-nine percent of the patients had chronic (> 12 months), 16% persistent (> 3-12 months), and 5% newly diagnosed (0-3 months) ITP. In 61% of cases, the disease lasted 3 or more years before survey documentation started. Main strategies applied as first-line therapy consisted of steroids in 45% and a "watch and wait" approach in 41% of patients. During second- and third-line strategies, treatment with steroids decreased (36% and 28%, respectively), while treatment modalities such as TPO-RAs increased (19% and 26%, respectively). As expected, patients with a low platelet count and thus a higher risk for bleeding and mortality received treatment (esp. steroids) more frequently during first line than those with a higher platelet count. Up to a third of patients were treated with steroids for more than a year. Overall, our study provides a cross-section overview about the current therapeutic treatment landscape in German ITP patients. The results will help to improve therapeutic management of ITP patients.

In patients with severe emphysema, dynamic hyperinflation is superimposed on top of already existing static hyperinflation. Static hyperinflation reduces significantly after bronchoscopic lung volume reduction (BLVR). In this study, we investigated the effect of BLVR compared to standard of care (SoC) on dynamic hyperinflation.

Dynamic hyperinflation was induced by a manually paced tachypnea test (MPT) and was defined by change in inspiratory capacity (IC) measured before and after MPT. Static and dynamic hyperinflation measurements were performed both at baseline and 6months after BLVR with endobronchial valves or coils (treatment group) or SoC (control group).

Eighteen patients underwent BLVR (78% female, 57 (43-67) years, FEV

25(18-37) %predicted, residual volume 231 (182-376) %predicted). Thirteen patients received SoC (100% female, 59 (44-74) years, FEV

25 (19-37) %predicted, residual volume 225 (152-279) %predicted. selleck chemicals llc The 6 months median change in dynamic hyperinflation in the treatment group was + 225ml (range - 113 to + 803) (p < 0.01) vs 0ml (- 1067 to + 500) in the control group (p = 0.422). An increase in dynamic hyperinflation was significantly associated with a decrease in residual volume (r = - 0.439, p < 0.01).

Bronchoscopic lung volume reduction increases the ability for dynamic hyperinflation in patients with severe emphysema. We propose this is a consequence of improved static hyperinflation.
