Attenuating Effect of Long-term Culture of Umbilical Cord Vein Mesenchymal Stromal Cells on Pulmonary Fibrosis in C57BL/6 Mice.In recent studies, mesenchymal stromal cells (MSCs) have been increasingly employed to treat various diseases like pulmonary fibrosis (PF). There are very few MSCs in tissues so in order to obtain their sufficient numbers for therapeutic applications, their in vitro expansion is necessary. The aim of this study was to investigate the effects of long-term culture of the human umbilical cord vein MSCs (hUCV-MSCs) on pulmonary fibrosis in mice. MSCs were first isolated from human umbilical cord vein and cultured up to 18 passages. In C57BL/6 mice, 15 min after belomycin instillation, UCV-MSCs at passages (P) 0, 4, 8, 12, and 18 (long-term culture) were transplanted intratracheally. Mice were weighted every 5 days and were euthanized on day 21. For histopathological examination, the lung sections were stained with hematoxylin-eosin (HE) and Masson's trichrome. The mRNA expression of TGF-β1, alpha-smooth muscle actin (α-SMA), and collagen type I alpha 1 (COL1A1) in lung tissues were assessed using RT-PCR. For cell tracking, human cytochrome B DNA was detected in mice lung tissues by PCR. The weight of mice receiving long-term culture of UCV-MSCs increased compared to other mice (p=0.056). Also, transplantation of UCV-MSCs at P18 led to increased alveolar space and decreased connective tissue and collagen deposition of the lung tissues. The mRNA expression of TGF-β1, α-SMA, and COL1A1 also decreased in this group. The results showed that intratracheally transplanted long-term culture of the UCV-MSCs attenuated lung fibrosis in mice.

Development of fisetin-loaded folate functionalized pluronic micelles for breast cancer targeting.The natural flavonoid fisetin (FS) has shown anticancer properties but its in-vivo administration remains challenging due to its poor aqueous solubility. The aim of the study was to develop FS loaded pluronic127 (PF)-folic acid (FA) conjugated micelles (FS-PF-FA) by the way of increasing solubility, bioavailability and active targetability of FS shall increase its therapeutic efficacy. FA-conjugated PF was prepared by carbodiimide crosslinker chemistry. FS-PF-FA micelles were prepared by thin-film hydration method and evaluated in comparison with free FS and FS loaded PF micelles (FS-PF). The smooth surfaces with spherical in shape of FS-PF-PF micelles displayed smaller in size (103.2 ± 6.1 nm), good encapsulation efficiency (82.50 ± 1.78%), zeta potential (-26.7 ± 0.44 mV) and sustained FS release. Bioavailability of FS from FS-PF-PF micelles was increased by 6-fold with long circulation time, slower plasma elimination and no sign of tissue toxicity as compared to free FS. Further, the FS-PF-FA micelles demonstrated active targeting effect on folate overexpressed human breast cancer MCF-7 cells. The concentration of the drug needed for growth inhibition of 50% of cells in a designed time period (GI50) was 14.3 ± 1.2 µg/ml for FS while it was greatly decreased to 9.8 ± 0.78 µg/ml, i.e. a 31.46% decrease for the FS-PF. Furthermore, the GI50 value for FS-PF-FA was 4.9 ± 0.4 µg/ml, i.e. a 65.737% decrease compared to FS and 50% decrease compare to FS-PF. The results indicate that the FS-PF-FA micelles have the potential to be applied for targeting anticancer drug delivery.

A phase 1, dose-escalation study of PF-06664178, an anti-Trop-2/Aur0101 antibody-drug conjugate in patients with advanced or metastatic solid tumors.Purpose and Methods Trop-2 is a glycoprotein over-expressed in many solid tumors but at low levels in normal human tissue, providing a potential therapeutic target. We conducted a phase 1 dose-finding study of PF-06664178, an antibody-drug conjugate that targets Trop-2 for the selective delivery of the cytotoxic payload Aur0101. The primary objective was to determine the maximum tolerated dose and recommended phase 2 dose. Secondary objectives included further characterization of the safety profile, pharmacokinetics and antitumor activity. Eligible patients were enrolled and received multiple escalating doses of PF-06664178 in an open-label and unblinded manner based on a modified continual reassessment method. Results Thirty-one patients with advanced or metastatic solid tumors were treated with escalating doses of PF-06664178 given intravenously every 21 days. Doses explored ranged from 0.15 mg/kg to 4.8 mg/kg. Seven patients experienced at least one dose limiting toxicity (DLT), either neutropenia or rash. Doses of 3.60 mg/kg, 4.2 mg/kg and 4.8 mg/kg were considered intolerable due to DLTs in skin rash, mucosa and neutropenia. Best overall response was stable disease in 11 patients (37.9%). None of the patients had a partial or complete response. Systemic exposure of PF-06664178 increased in a dose-related manner. Serum concentrations of free Aur0101 were substantially lower than those of PF-06664178 and total antibody. No correlation of Trop-2 expression and objective response was observed, although Trop-2 overexpression was not required for study entry. The intermediate dose of 2.4 mg/kg appeared to be the highest tolerated dose, but this was not fully explored as the study was terminated early due to excess toxicity. Conclusion PF-06664178 showed toxicity at high dose levels with modest antitumor activity. Neutropenia, skin rash and mucosal inflammation were dose limiting toxicities. Findings from this study may potentially aid in future antibody drug conjugate design and trials.

Unraveling the differential structural stability and dynamics features of T7 endolysin partially folded conformations.Characterization of partially collapsed protein conformations at atomic level is a daunting task due to their inherent flexibility and conformational heterogeneity. T7 bacteriophage endolysin (T7L) is a single-domain amidase that facilitates the lysis of Gram-negative bacteria. T7L exhibits a pH-dependent structural transition from native state to partially folded (PF) conformation. In the pH range 5-3, T7L PF states display differential ANS binding characteristics.

Spark Plasma Sintering (SPS)-Assisted Synthesis and Thermoelectric Characterization of Magnéli Phase V6O11.The Magnéli phase V6O11 was synthesized in gram amounts from a powder mixture of V6O11/V7O13 and vanadium metal, using the spark plasma sintering (SPS) technique. Its structure was determined with synchrotron X-ray powder diffraction data from a phase-pure sample synthesized by conventional solid-state synthesis. A special feature of Magnéli-type oxides is a combination of crystallographic shear and intrinsic disorder that leads to relatively low lattice thermal conductivities. SPS prepared V6O11 has a relatively low thermal conductivity of κ = 2.72 ± 0.06 W (m K)-1 while being a n-type conductor with an electrical conductivity of σ = 0.039 ± 0.005 (μΩ m)-1, a Seebeck coefficient of α = -(35 ± 2) μV K-1, which leads to a power factor of PF = 4.9 ± 0.8 × 10-5W (m K2)-1 at ∼600 K. Advances in the application of Magnéli phases are mostly hindered by synthetic and processing challenges, especially when metastable and nanostructured materials such as V6O11 are involved. This study gives insight into the complications of SPS-assisted synthesis of complex oxide materials, provides new information about the thermal and electrical properties of vanadium oxides at high temperatures, and supports the concept of reducing the thermal conductivity of materials with structural building blocks such as crystallographic shear (CS) planes.

[Age-related changes of water transport by corneal endothelial cells in rats.]Senescence-associated alterations in structure and function of cornea make it more sensitive to traumas and disease. Trauma of cornea leads to edema and vision impairment and only corneal transplantation remains the effective for vision correction. Role of aquaporins for cornea endothelium function, as well as age-related changes of their activity, are not entirely understood. Herein, we studied changes with age the water permeability (Pf) of the plasma membranes of the corneal endothelial cells and the level of expression in them of the mRNA genes of the water channels of the aquaporins AQP1 and AQP3 in Wistar and senescence-accelerated OXYS rats. From the age of 3 to 18 months, Pf in Wistar rats increased, in OXYS - decreased and was twice lower than in Wistar rats. The expression of aqp1 mRNA (studied by RT-PCR) in the endothelium was the same in Wistar and OXYS rats at the age of 3 months. By the age of 18 months, it increased only in Wistar rats and became twice higher than in OXYS rats. The expression of aqp3 mRNA in the endothelium of 3-month-old OXYS rats was half that of Wistar rats and did not change with age, while in Wistar rats it decreased and at 18 months was 4 times lower than in 3 months. We supposed that increased water permeability of endothelial cells in Wistar rats is adaptive and compensates for the decrease in endothelial cell density with age, while the accelerated aging of OXYS rats abolishes this compensation.
