The value of rates of change in FEV1 and DLCO to predict disease progression, and initiation of mTOR inhibitor therapy has not been evaluated.In 84 pre-menopausal LAM patients, individual rates of change in FEV1 and DLCO and 95% confidence intervals (CI), were used to derive subsequent lowest values of FEV1 and DLCO that would prompt initiation of sirolimus therapy. These treatment criteria were compared with one based on FEV1 or DLCO ≤70% predicted. In 12 patients undergoing sirolimus therapy both methods for determining the optimal point for initiation of therapy were evaluated...

Throughout the animal kingdom, the Notch signalling pathway allows cells to acquire diversified cell fates. Notch signals are translated into activation of Notch target genes by CSL transcription factors. In the absence of Notch signals, CSL together with co-repressors functions as a transcriptional repressor. In Drosophila, repression of Notch target genes involves the CSL homologue Suppressor of Hairless (Su(H)) and the Notch (N) antagonist Hairless (H) that together form a repressor complex. Guided by crystal structure, three mutations Su(H)LL, Su(H)LLF and Su(H)LLL were generated that specifically affect interactions with the repressor H, and were introduced into the endogenous Su(H) locus by gene engineering...

Plants photosynthesis-related traits are co-regulated to capture light and CO2 to optimize the rate of CO2 assimilation (A). The rising CO2 often benefits, but potassium (K) deficiency adversely affects A that contributes to the majority of plant biomass. To evaluate mechanisms of photosynthetic limitations and adaptations, soybean was grown under controlled conditions with an adequate (control, 5.0 mM) and two K-deficient (moderate, 0.50 and severe, 0.02 mM) levels under ambient (aCO2 ; 400 µmol mol-1 ) and elevated CO2 (eCO2 ; 800 µmol mol-1 )...

BF-30 is a single chain polypeptide of an N-segment with an α-helix from cathelicidin gene encoding, and it contains 30 amino acid residues, with a relative molecular mass and isoelectric point of 3637.54 and 11.79, respectively. Cathelicidin-BF-30 was entrapped in four-arm star-shaped poly(ethylene glycol-b-dl-lactic acid-co-glycolic acid) block copolymers (4-arm-PEG-PLGA) by a double-emulsion solvent-evaporation method. Three release phases of cathelicidin-BF-30loaded 4-arm-PEG-PLGA microspheres were observed, including an initial burst-release phase, followed by a lag phase with minimal drug release and finally a secondary zero-order release phase...

Diabetes in older adults has a high prevalence and is frequently associated with comorbidities of the cardiovascular system, dysfunction of cognition as well as depression and impaired mobility or increased frailty. Furthermore, impaired renal function, heart failure, risk for hypoglycemia and polypharmacy has to be considered in the decision about the diabetes treatment strategy. The goal of blood glucose management is driven by patient relevant issues and patient self-esteem, quality of life defined by the patient, preservation of physical and social mobility rather than potential long-term effects on reduction of cardio- and microvascular events in the future, which is limited by patient-inherent reduced life expectancy of the aged individual...

Following implantation of a left ventricular assist device (LVAD), acceptable functional performance is now being achieved; however, peak VO 2 and peak work load (watts) remain considerably limited. Maximum physical capacity is essentially dependent on generated cardiac output (CO) and arteriovenous oxygen difference (avDO 2 ). We investigated the changes in CO and avDO 2 during exercise in LVAD patients with an HVAD pump (HeartWare Inc., Framingham, MA, USA). Approximately 6 weeks after implantation, 20 patients (100% male, 60...
