    ABSTRACT: To facilitate drug development for lung delivery, it is highly demanding to establish appropriate airway epithelial cell models as transport barriers to evaluate pharmacokinetic profiles of drug molecules. Besides the cancer-derived cell lines, as the primary cell model, normal human bronchial epithelial (NHBE) cells have been used for drug screenings because of physiological relevance to in vivo. Therefore, to accurately interpret drug transport data in NHBE measured by different laboratories, it is important to know biophysical characteristics of NHBE grown on membranes in different culture conditions. In this study, NHBE was grown on the polyester membrane in a different medium and its transport barrier properties as well as cell architectures were fully characterized by functional assays and confocal imaging throughout the days of cultures. Moreover, NHBE cells on inserts in a different medium were subject to either of air-interfaced culture (AIC) or liquid-covered culture (LCC) condition. Cells in the AIC condition were cultivated on the membrane with medium in the basolateral side only, whereas cells with medium in apical and basolateral sides under the LCC condition. Quantitative microscopic imaging with biophysical examination revealed distinct multilayered architectures of differentiated NHBE cells, suggesting NHBE as functional cell barriers for the lung-targeting drug transport.

    ABSTRACT: Guided bone regeneration (GBR) is a principle adopted from guided tissue regeneration (GTR). Wherein, GBR is used for the healing of peri-implant bony dehiscences, for the immediate placement of implants into extraction sockets and for the augmentation of atrophic alveolar ridges. This procedure is done by the placement of a resorbable or non-resorbable membrane that will exclude undesirable types of tissue growth between the extraction socket and the soft tissue to allow only bone cells to regenerate in the surgically treated lesion. Here, we investigated the biodegradable effect of polylactic-co-glycolic acid (PLGA) membrane in the alveolar bone on Beagle dogs. Results show that both collagen and PLGA membrane had been fully resorbed, biodegraded, at four weeks post-operative reentry into the alveolar bone. Histological results under light microscopy revealed formation of new bone trabeculae in the extraction sites on both collagen and PLGA membrane. In conclusion, PLGA membrane could be a potential biomaterials for use on GBR and GTR. Nevertheless, further studies will be necessary to elucidate the efficiency and cost effectiveness of PLGA as GBR membrane in clinical.

    ABSTRACT: To assess the image quality of monochromatic imaging from spectral CT in patients with Budd-Chiari syndrome (BCS), fifty patients with BCS underwent spectral CT to generate conventional 140 kVp polychromatic images (group A) and monochromatic images, with energy levels from 40 to 80, 40 + 70, and 50 + 70 keV fusion images (group B) during the portal venous phase (PVP) and the hepatic venous phase (HVP). Two-sample t tests compared vessel-to-liver contrast-to-noise ratio (CNR) and signal-to-noise ratio (SNR) for the portal vein (PV), hepatic vein (HV), inferior vena cava. Readers' subjective evaluations of the image quality were recorded. The highest SNR values in group B were distributed at 50 keV; the highest CNR values in group B were distributed at 40 keV. The higher CNR values and SNR values were obtained though PVP of PV (SNR 18.39 ± 6.13 vs. 10.56 ± 3.31, CNR 7.81 ± 3.40 vs. 3.58 ± 1.31) and HVP of HV (3.89 ± 2.08 vs. 1.27 ± 1.55) in the group B; the lower image noise for group B was at 70 keV and 50 + 70 keV (15.54 ± 8.39 vs. 18.40 ± 4.97, P = 0.0004 and 18.97 ± 7.61 vs. 18.40 ± 4.97, P = 0.0691); the results show that the 50 + 70 keV fusion image quality was better than that in group A. Monochromatic energy levels of 40-70, 40 + 70, and 50 + 70 keV fusion image can increase vascular contrast and that will be helpful for the diagnosis of BCS, we select the 50 + 70 keV fusion image to acquire the best BCS images.

    ABSTRACT: To determine the optimal velocity values in diagnosing unilateral middle cerebral artery (MCA) stenosis by Transcranial Doppler (TCD), and improve the diagnostic accuracy using magnetic resonance angiography (MRA), a total of 302 unilateral MCA stenosis patients undergoing TCD also consented to a MRA of the intracranial arteries. The peak systolic velocity (PSV) and each MCA spectrum for each patient were recorded. Using the MRA to confirm, the degree of middle cerebral artery stenosis was categorized into four groups: normal (normal caliber and signal), mild (<50 %), moderate (50-69 %), severe (70-99 %, or no flow detected). The velocity difference among these four groups was significant (P < 0.001). The optimal PSV values for normal and stenosis were 160 cm/s. For mild and moderate were 200 cm/s, for moderate and severe were 280 cm/s. Using PSV as the diagnostic criteria, the Kappa number was >0.668. The optimal PSV differential value for mild and moderate was 70 cm/s, for moderate and severe at 120 cm/s. Optimal combined criteria for moderate stenosis were PSV >200 cm/s and PSV differential value >70 cm/s (specificity 87.2 %), for severe stenosis were PSV >280 cm/s and PSV differential value >120 cm/s (sensibility 81.6 %). Transcranial Doppler distinguishes normal and MCA stenosis with a reduced lumen diameter of less than 50 %. Using the PSV criteria, TCD has a high coincidence rate with MRA in the diagnosis of MCA stenosis. Combined PSV differential value and the abnormal spectrum may improve the accuracy of TCD in diagnosing moderate or severe stenosis.

    ABSTRACT: Accumulated evidences implicated that microRNAs may be involved in diabetic neuropathy. Here, we investigated miR-29's roles in primary isolated dorsal root ganglion (DRG) neurons from STZ-induced diabetic rats. First, miR-29b was found down-regulated after STZ-injection. Inhibitions were increased with time course. Down-regulation of miR-29b was associated with higher apoptosis rate and more serious axonal swelling. Meanwhile, axonogeneration genes were inhibited, whereas neurodegenerative genes were stimulated. Restoration of miR-29b by mimic experiment could reverse the above neuropathy. Furthermore, western blot analysis disclosed that miR-29b could abolish Smad3 activation. In conclusion, the present study identifies that miR-29b could protect DRG from diabetic rats. This protective effects suggested potential therapeutic application of miR-29b in diabetic neuropathy.

    ABSTRACT: Fanconi anemia (FA) is an autosomal recessive human disease characterized by genomic instability and a marked increase in cancer risk. The importance of FANCD1 gene is manifested by the fact that deleterious amino acid substitutions were found to confer susceptibility to hereditary breast and ovarian cancers. Attaining experimental knowledge about the possible disease-associated substitutions is laborious and time consuming. The recent introduction of genome variation analyzing in silico tools have the capability to identify the deleterious variants in an efficient manner. In this study, we conducted in silico variation analysis of deleterious non-synonymous SNPs at both functional and structural level in the breast cancer and FA susceptibility gene BRCA2/FANCD1. To identify and characterize deleterious mutations in this study, five in silico tools based on two different prediction methods namely pathogenicity prediction (SIFT, PolyPhen, and PANTHER), and protein stability prediction (I-Mutant 2.0 and MuStab) were analyzed. Based on the deleterious scores that overlap in these in silico approaches, and the availability of three-dimensional structures, structure analysis was carried out with the major mutations that occurred in the native protein coded by FANCD1/BRCA2 gene. In this work, we report the results of the first molecular dynamics (MD) simulation study performed to analyze the structural level changes in time scale level with respect to the native and mutated protein complexes (G25R, W31C, W31R in FANCD1/BRCA2-PALB2, and F1524V, V1532F in FANCD1/BRCA2-RAD51). Analysis of the MD trajectories indicated that predicted deleterious variants alter the structural behavior of BRCA2-PALB2 and BRCA2-RAD51 protein complexes. In addition, statistical analysis was employed to test the significance of these in silico tool predictions. Based on these predictions, we conclude that the identification of disease-related SNPs by in silico methods, in combination with MD approach has the potential to create personalized tools for the diagnosis, prognosis, and treatment of diseases. The methods reviewed here generated a considerable amount of valuable data, but also the need for further validation.

    ABSTRACT: Pulmonary alveolar microlithiasis (PAM) is a rare autosomal recessive disease characterized by the presence of innumerable calcium phosphate microliths in the alveoli. Clinical-radiological dissociation is an important hallmark of this disease. Most PAM patients are asymptomatic and pulmonary tissue changes are discovered incidentally. PAM is pathologically attributable to the formation and aggregation of calcium phosphate microliths in the alveoli after mutations in the SLC34A2 gene (the type IIb sodium-phosphate cotransporter gene) coding NaPi-IIb. In the clinical work, we discovered an inbred pedigree with PAM, which include four PAM siblings. We performed a sequence analysis of the SLC34A2 gene in all members of this PAM pedigree and found that a homozygous mutation c.575C > A (p.T192 K) in exon 6 was involved. To the best of our knowledge, this study was the first to discover nucleotide mutations in exon 6 in Asians.

    ABSTRACT: Recent studies have shown that endothelial progenitor cells (EPCs) participated in angiogenic effects of nicotine and nicotine dose dependently increased the functional activity of early EPCs. The effects of nicotine on late EPCs remain to be determined. Therefore, we investigated whether nicotine had influences on the functional activity of late EPCs. Late EPCs were isolated from human umbilical cord blood and characterized. Late EPCs of 3-5 passages were treated for 32 h with either vehicle or nicotine. The proliferative, migratory, and in vitro vasculogenesis activities of late EPCs were assayed with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, modified Boyden chamber assay, and in matrigel, respectively. Late EPCs adhesion assay was performed by replating cells on fibronectin-coated dishes, and then adherent cells were counted. Nicotine enhanced proliferative, migratory, adhesive, and in vitro vasculogenesis capacities of late EPCs. These effects were significantly reduced in the presence of phosphatidylinositol (PI) 3-kinase inhibitor.

    ABSTRACT: Tendon stem cells (TSCs), recently identified as tendon cells, play an important role in maintaining the homeostasis of tendon tissue. Age-related decrease in the function of TSCs has been reported. Recent reports demonstrated that hypoxic condition is advantageous for efficient expansion of TSCs. Moreover, the impaired function of aged stem cells could be modulated by exposing them to a young environment. Therefore, we investigated the effects of hypoxic-conditioned culture medium (HCCM) from young TSCs on the proliferation, migration, senescence, and tenocyte phenotype of aged TSCs. TSCs were isolated, and the conditioned medium was collected. There were 4 groups: young TSCs, aged TSCs, aged TSCs + aged HCCM, and aged TSCs + young HCCM. The proliferative capacity, migration, β-galactosidase activity, and tenogenic differentiation potential of TSCs were assessed. Our results showed that HCCM enhanced the proliferation and migration potential of aged TSCs. Moreover, the senescence-associated β-galactosidase activity of aged TSCs was decreased by young HCCM. After being cultured in the young HCCM, the expressions of tenocyte-related genes in aged TSCs were significantly enhanced. Together, results of this study indicate that HCCM from young TSCs may represent an effective strategy to improve the impaired function of aged TSCs.

    ABSTRACT: The AKT1 gene is of supreme importance in cell signaling and human cancer. In the present study, we aim to understand the phenotype variations that were believed to have the highest impact in AKT1 gene by different computational approaches. The analysis was initiated with SIFT tool followed by PolyPhen 2.0, I-Mutant 2.0, and SNPs&GO tools with the aid of 22 nonsynonymous (nsSNPs) retrieved from dbSNP. A total of five AKT1 variants such as E17K, E17S, E319G, L357P, and P388T are found to exert deleterious effects on the protein structure and function. Furthermore, the molecular docking study indicates the lesser binding affinity of inhibitor with the mutant structure than the native type. In addition, root mean square deviation and hydrogen bond details were also analyzed in the 10 ns molecular dynamics simulation study. These computational evidences suggested that E17K, E17S, E319G, L357P, and P388T variants of AKT1 could destabilize the protein networks, thus causing functional deviations of protein to some extent. Moreover, the findings strongly indicate that screening for AKT1, E17K, E17S, E319G, L357P, and P388T variants may be useful for disease molecular diagnosis and also to design the potential AKT inhibitors.
