Abstract
INTRODUCTION The significantly higher mortality rate in the critical illness patients with Pseudomonas aeruginosa (PA) infection is linked to inappropriate selecting of empirical treatment. Traditional local antibiogram provides clinicians the resistant rate of a single antimicrobial agent to the pathogen in the specific setting. The information is valuable to the clinicians in selecting suitable empirical antibiotic therapy. However, traditional local antibiogram can only provide information for single agent empirical antibiotic not combination regimens. The combination antibiogram should be developed to facilitate the selection of appropriate antibiotics to broader the coverage rate of resistant PA. METHODS The susceptibility to the β-lactam antibiotics (piperacillin/tazobactam (PTZ), ceftazidime, cefepime, imipenem, or meropenem) or to those administered in combination with an aminoglycoside (gentamicin or amikacin) or fluoroquinolone (ciprofloxacin or levofloxacin) was calculated. The chi-square test was used to compare the differences of combination coverage rates between non-ICU and ICU isolates. RESULTS 880 PA isolates were isolated during study period. The susceptibility of single agents ranged from 83.1% to 89.7%. The combination regimens containing amikacin provide the highest cover rate (98.9%-99.1%) and those containing levofloxacin provide less coverage rate (92.3%-93.9%). The susceptibility to five β-lactam single agents in ICU isolates significantly lower than non-ICU isolates. The non-ICU isolates exhibited significantly higher susceptibility to the PTZ-gentamicin (p = 0.002) and ceftazidime-gentamicin (p = 0.025) than ICU isolates. CONCLUSION Our results support the use of aminoglycosides instead of fluoroquinolones as additive agents in empirical combination treatments for patients with critical infections caused by PA.

Abstract
Multimodal neural interfaces include combined functions of electrical neuromodulation and synchronic monitoring of neurochemical and physiological signals in one device. The remarkable biocompatibility and electrochemical performance of polystyrene sulfonate-doped poly(3,4-ethylenedioxythiophene) (PEDOT:PSS) have made it the most recommended conductive polymer neural electrode material. However, PEDOT:PSS formed by electrochemical deposition, called PEDOT/PSS, often need multiple doping to improve structural instability in moisture, resolve the difficulties of functionalization, and overcome the poor cellular affinity. In this work, inspired by the catechol-derived adhesion and semiconductive properties of polydopamine melanin (PDAM), we used electrochemical oxidation polymerization to develop PDAM-doped PEDOT (PEDOT/PDAM) as a bioactive multimodal neural interface that permits robust electrochemical performance, structural stability, analyte-trapping capacity, and neural stem cell affinity. The use of potentiodynamic scans resolved the problem of copolymerizing 3,4-ethylenedioxythiophene (EDOT) and dopamine (DA), enabling the formation of PEDOT/PDAM self-assembled nanodomains with an ideal doping state associated with remarkable current storage and charge transfer capacity. Owing to the richness of hydrogen bond donors/acceptors provided by the hydroxyl groups of PDAM, PEDOT/PDAM presented better electrochemical and mechanical stability than PEDOT/PSS. It has also enabled high sensitivity and selectivity in the electrochemical detection of DA. Different from PEDOT/PSS, which inhibited the survival of human induced pluripotent stem cell-derived neural progenitor cells, PEDOT/PDAM maintained cell proliferation and even promoted cell differentiation into neuronal networks. Finally, PEDOT/PDAM was modified on a commercialized microelectrode array system, which resulted in the reduction of impedance by more than one order of magnitude; this significantly improved the resolution and reduced the noise of neuronal signal recording. With these advantages, PEDOT/PDAM is anticipated to be an efficient bioactive multimodal neural electrode material with potential application to brain-machine interfaces.

Abstract
AbstractPulmonary sequelae following COVID-19 pneumonia have been emerging as a challenge; however, suitable cell sources for studying COVID-19 mechanisms and therapeutics are currently lacking. In this paper, we present a standardized primary alveolar cell culture method for establishing a human alveolar epithelium model that can recapitulate viral infection and cellular plasticity. The alveolar model is infected with a SARS-CoV-2 pseudovirus, and the clinically relevant features of the viral entry into the alveolar type-I/II cells, cytokine production activation, and pulmonary surfactant destruction are reproduced. For this damaged alveolar model, we find that the inhibition of Wnt signaling via XAV939 substantially improves alveolar repair function and prevents subsequent pulmonary fibrosis. Thus, the proposed alveolar cell culture strategy exhibits potential for the identification of pathogenesis and therapeutics in basic and translational research.

Abstract
Injectable cell-based hydrogels allow surgical operation in a minimally invasive way for articular cartilage lesions but the chondrocytes in the injectable hydrogels are difficultly arrayed and fixed at the site of interest to repair the cartilage tissue. In this study, an injectable hyaluronic acid-polyacrylic acid (HA-pAA) hydrogel was first synthesized using hyaluronic acid-cyclodextrin (HA-CD) and polyacrylic acid-ferrocene (pAA-Fc) to provide cell-delivery and self-healing. To promote the cell fixation and alignment, porous poly(lactic-co-glycolic acid) (PLGA) magnetic microcapsules (PPMMs) with glutathione (GSH) loaded and iron oxide nanoparticles (IO) located in the shell were designed. The GSH-loaded PPMMs with layer-by-layer (LbL) assembly of hyaluronic acid (HA) and GSH (LbL-PPMMs) can provide a two-stage rapid and slow release of GSH to modulate the self-healing of the HA-pAA hydrogel at the injured site. Furthermore, the chondrocytes embedded in the HA-pAA hydrogel could be delivered through CD44 receptors on the HA polymer chains of LbL-PPMMs toward the surface of the damaged site by an internal magnetic force. The composite hydrogel system of chondrocytes/LbL-PPMMs/HA-pAA can provide the damaged cartilage with a more even and smooth surface than other groups in a rabbit model after 8 weeks of implantation. In addition, the chondrocytes in the deep zone tissue exhibit a columnar array, similar to the cell arrangement in normal cartilage tissue. Together with the cell navigation behavior and GSH release from the LbL-PPMM/HA-pAA hydrogel, a full closure of lesions on the cartilage tissue can be achieved. Our results demonstrate the highly promising potential of the injectable LbL-PPMM/HA-pAA system in cartilage tissue repair.

Abstract
Immunotherapy is a newly developed method for cancer treatment, but still generates limited response in partial patients for hepatocellular carcinoma (HCC) because the immunity cycle is limited by the tumor microenvironment (TME). Herein, we introduce multifunctional gold nanocages (AuNCs)-based nanocarriers with Ansamitocin P3 (AP3) loaded and anti-PDL1 binding (AP3-AuNCs-anti-PDL1) which can combine photothermal therapy, chemotherapeutic agent-triggered DCs maturation, and checkpoint immunotherapy in one platform. The AP3-AuNCs-anti-PDL1 using Avidin-biotin to bind anti-PDL1 on the surface of AP3-AuNCs showed specifically cellular targeting compared to AuNCs, which can increase the immune responses. The AP3-AuNCs+NIR-10 min exhibited the highly activated DCs maturation with two-fold higher than control+NIR, which can be attributed to the significant release of AP3. The results illustrated the synergistic effect of tumor-associated antigens (TAAs) and controlled AP3 release under near infrared (NIR) in triggering effective DCs maturation. Among them, AP3 release played the more important role than the TAAs under PTT in promoting T-cell activation. These results illustrate the promising potential of AuNCs-based nanocarriers combined with AP3 and the checkpoint inhibitors to strengthen the positive loop of immunity cycle.

Abstract
ALDH2 gene is coded for the aldehyde dehydrogenase (ALDH), which is an enzyme involved in alcohol metabolism. Compared to normal aldehyde dehydrogenases, a homozygous point mutation on exon 12 from G to A significantly reduces its efficiency. In this study, we have reported the generation of IBMS-iPSC-021-04, IBMS-iPSC-022-01, and IBMS-iPSC-023-03 as induced pluripotent stem cell (iPSC) lines carrying the homozygous form of ALDH2 with the rs671 genetic polymorphism (E487K mutation). These cell lines were characterized in terms of pluripotency and differentiation potential. They serve as useful platforms to study alcohol metabolism and other chronic diseases associated with alcohol consumption.

Abstract
Although traditional 3D scaffolds or biomimetic hydrogels have been used for tissue engineering and regenerative medicine, soft tissue microenvironment usually has a highly anisotropic structure and a dynamically controllable deformation with various biomolecule distribution. In this study, we developed a hierarchical hybrid gelatin methacrylate-microcapsule hydrogel (HGMH) with Neurotrophin-3(NT-3)-loaded PLGA microcapsules to fabricate anisotropic structure with patterned NT-3 distribution (demonstrated as striped and triangular patterns) by dielectrophoresis (DEP). The HGMH provides a dynamic biomimetic sinuate-microwrinkles change with NT-3 spatial gradient and 2-stage time-dependent distribution, which was further simulated using a 3D finite element model. As demonstrated, in comparison with striped-patterned hydrogel, the triangular-patterned HGMH with highly anisotropic array of microcapsules exhibits remarkably spatial NT-3 gradient distributions that can not only guide neural stem cells (NSCs) migration but also facilitate spinal cord injury regeneration. This approach to construct hierarchical 4D hydrogel system via an electromicrofluidic platform demonstrates the potential for building various biomimetic soft scaffolds in vitro tailed to real soft tissues.

Abstract
OBJECTIVES Enterococcus faecalis (E. faecalis), one of the main pathogens responsible for refractory periapical periodontitis and nosocomial infections, exhibits markedly higher pathogenicity in biofilms. Studies have shown that caseinolytic protease P (ClpP) is involved in biofilm formation. However, to date, few studies have investigated the role of ClpP in the survival of E. faecalis, and in enhancing biofilm formation. Therefore, we investigated the role of ClpP in the formation of E. faecalis biofilms. METHODOLOGY In our study, we used homologous recombination to construct clpP deleted and clpP complement strains of E. faecalis ATCC 29212. A viable colony counting method was used to analyze the growth patterns of E. faecalis. Crystal violet staining (CV) and confocal scanning laser microscopy (CLSM) were used to characterize biofilm mass formation and scanning electron microscopy (SEM) was used to observe the biofilm microstructure. Data was statistically analyzed via Student's t-test or one-way analysis of variance (ANOVA). RESULTS The results exhibited altered growth patterns for the clpP deletion strains and depleted polysaccharide matrix, resulting in reduced biofilm formation capacity compared to the standard strains. Moreover, ClpP was observed to increase biofilm formation in E. faecalis. CONCLUSION Our study shows that ClpP can increase biofilm formation in E. faecalis and emphasizes the importance of ClpP as a potential target against E. faecalis.

Abstract
The ALDH2 mutation (ALDH2*2) is caused by an amino acid substitution ALDH2 rs671 G>A (pE487K) which reduces ALDH2 enzyme activity. When individuals with the ALDH2 mutation consume alcohol, accumulating acetaldehyde in the blood can cause reddened face, headache, nausea, and palpitations; symptoms referred to as Alcohol Flushing Reaction. We report the production of an induced pluripotent stem cell (iPSC) line, FIRDIi001-A, developed from peripheral blood mononuclear cells of a 39-year-old male subject with the ALDH2*2 mutation. The ALDH2-pE487K iPSCs will be valuable in investigating pathogenic mechanisms involved in the link between the ALDH2 polymorphism and alcohol-related diseases.

Abstract
Background The Taiwan Human Disease iPSC Service Consortium was established to accelerate Taiwan’s growing stem cell research initiatives and provide a platform for researchers interested in utilizing induced pluripotent stem cell (iPSC) technology. The consortium has generated and characterized 83 iPSC lines: 11 normal and 72 disease iPSC lines covering 21 different diseases, several of which are of high incidence in Taiwan. Whether there are any reprogramming-induced recurrent copy number variant (CNV) hotspots in iPSCs is still largely unknown. Methods We performed genome-wide copy number variant screening of 83 Han Taiwanese iPSC lines and compared them with 1093 control subjects using an Affymetrix genome-wide human SNP array. Results In the iPSCs, we identified ten specific CNV loci and seven “polymorphic” CNV regions that are associated with the reprogramming process. Additionally, we established several differentiation protocols for our iPSC lines. We demonstrated that our iPSC-derived cardiomyocytes respond to pharmacological agents and were successfully engrafted into the mouse myocardium demonstrating their potential application in cell therapy. Conclusions The CNV hotspots induced by cell reprogramming have successfully been identified in the current study. This finding may be used as a reference index for evaluating iPSC quality for future clinical applications. Our aim was to establish a national iPSC resource center generating iPSCs, made available to researchers, to benefit the stem cell community in Taiwan and throughout the world.

Abstract
Recent developments in epidemiology have confirmed that airborne particulates are directly associated with respiratory pathology and mortality. Although clinical studies have yielded evidence of the effects of many types of fine particulates on human health, it still does not have a complete understanding of how physiological reactions are caused nor to the changes and damages associated with cellular and molecular mechanisms. Currently, most health assessment studies of particulate matter (PM) are conducted through cell culture or animal experiments. The results of such experiments often do not correlate with clinical findings or actual human reactions, and they also cause difficulty when investigating the causes of air pollution and associated human health hazards, the analysis of biomarkers, and the development of future pollution control strategies. Microfluidic-based cell culture technology has considerable potential to expand the capabilities of conventional cell culture by providing high-precision measurement, considerably increasing the potential for the parallelization of cellular assays, ensuring inexpensive automation, and improving the response of the overall cell culture in a more physiologically relevant context. This review paper focuses on integrating the important respiratory health problems caused by air pollution today, as well as the development and application of biomimetic organ-on-a-chip technology. This more precise experimental model is expected to accelerate studies elucidating the effect of PM on the human body and to reveal new opportunities for breakthroughs in disease research and drug development.

Abstract
A hexanucleotide repeat expansion in chromosome 9 open reading frame 72 (C9orf72) gene causes a heterogeneous neurodegenerative disorder that includes amyotrophic lateral sclerosis (ALS), frontotemporal degeneration (FTD), and parkinsonism. Here, we used the Sendai virus delivery system to generate induced pluripotent stem cells (iPSCs) from peripheral blood mononuclear cells of a male patient with an increased hexanucleotide repeat expansion in C9orf72. The resulting iPSCs exhibited pluripotency, confirmed by immunofluorescent staining for pluripotency markers, and differentiated into three germ layers in vivo. This cellular model will provide a useful platform for further pathophysiological studies of C9orf72-related neurodegeneration.

Abstract
Hearing loss is the most common disorder in the sensory system. Mutations in GJB2 have been reported to be very common in sensorineural hearing loss patients. In this report, we generated an induced pluripotent stem cell (iPSC) line, MMCi001-A, from the peripheral blood mononuclear cells of a 4-year-old male hearing loss patient carrying GJB2 pV37I mutation by using the Sendai virus delivery system. The generated iPSCs were demonstrated to express pluripotent markers and be differentiated into three germ layers in vitro and in vivo. This GJB2-pV37I iPSCs is valuable for studying the pathogenic mechanisms and drug discovery of hearing loss.

Abstract
Current research has enabled the use of microphysiological systems and creation of models for alveolar and pulmonary diseases. However, bottlenecks remain in terms of medium- and long-term regulation of cell cultures and their functions in microchannel systems, as well as in the enhancement of in vitro representation of alveolar models and reference values of the data. Currently used systems also require on-chip manufacturing of complex units, such as pumps, tubes, and other cumbersome structures for maintaining cells in culture. In addition, system simplification and minimization of all external and human factors major challenges facing the establishment of in vitro alveolar models. In this study, a magnetically driven dynamic alveolus cell-culture system has been developed to use controlled magnetic force to drive a magnetic film on the chip, thereby directing the fluid within it to produce a circulating flow. The system has been confirmed to be conducive with regard to facilitating uniform attachment of human alveolar epithelial cells and long-term culture. The cell structure has been recapitulated, and differentiation functions have been maintained. Subsequently, reactions between silica nanoparticles and human alveolar epithelial cells have been used to validate the effects and advantages of the proposed dynamic chip-based system compared to a static environment. The innovative concept of use of a magnetic drive has been successfully employed in this study to create a simple and controllable yet dynamic alveolus cell-culture system to realize its functions and advantages with regard to in vitro tissue construction.

Abstract
Leucine rich repeat kinase 2 (LRRK2) is the causative gene for autosomal-dominant familial forms of Parkinson's disease (PD). Here, we generated induced pluripotent stem cells (iPSCs) from the peripheral blood mononuclear cells of a female patient with LRRK2 c.4111A > G (p.I1371V) mutation by using the Sendai-virus delivery system. The resulting iPSCs had a normal karyotype. The iPSCs also showed pluripotency confirmed by immunofluorescent staining and differentiated into the three germ layers in vivo. This cellular model will provide a platform for studying the role of LRRK2 in the disease process.

Abstract
Turner's syndrome (TS) is one of the main causes of premature ovarian failure (POF). However, the mechanisms underlying POF are difficult to study due to the lack of suitable disease models. Herein, we have generated a human induced pluripotent stem cell (hiPSC) line derived from the peripheral blood mononuclear cells of a female patient with Turner's syndrome mosaicism via integration-free Sendai-virus system. The hiPSCs were confirmed with a 45, X karyotype and the acquisition of pluripotency. It's likely that hiPSCs can serve as a feasible cellular model for further pathophysiological studies of POF cases, especially for those originating in TS.

A recessive mutation in PLA2G6, which is known to cause a heterogeneous neurodegenerative clinical spectrum, has recently been shown to be responsible for autosomal-recessive familial forms of Parkinson's disease (PD). Here, we generated induced pluripotent stem cells (iPSCs) from the peripheral blood mononuclear cells of a female patient with a homozygous PLA2G6 c.991G > T (p.D331Y) mutation by using the Sendai-virus delivery system. The resulting iPSCs showed pluripotency confirmed by immunofluorescent staining for pluripotency markers and differentiated into the 3 germ layers in vivo. This cellular model will provide a good resource for further pathophysiological studies of PD.

Abstract
X-linked juvenile retinoschisis (XLRS) is a hereditary retinal dystrophy manifested as splitting of anatomical layers of retina. In this report, we generated a patient-specific induced pluripotent stem cell (iPSC) line, TVGH-iPSC-013-05, from the peripheral blood mononuclear cells of a male patient with XLRS by using the Sendai-virus delivery system. We believe that XLRS patient-specific iPSCs provide a powerful in vitro model for evaluating the pathological phenotypes of the disease.

Abstract
Best disease (BD), also termed Best vitelliform macular dystrophy (BVMD), is a juvenile-onset form of macular degeneration and central visual loss. In this report, we generated an induced pluripotent stem cell (iPSC) line, TVGH-iPSC-012-04, from the peripheral blood mononuclear cells of a female patient with BD by using the Sendai virus delivery system. The resulting iPSCs retained the disease-causing DNA mutation, expressed pluripotent markers and could differentiate into three germ layers. We believe that BD patient-specific iPSCs provide a powerful in vitro model for evaluating the pathological phenotypes of the disease.

Abstract
Leucine rich repeat kinase (LRRK2) is the most prevalent genetic cause for Parkinson's disease. LRRK2 p.G2385R is an Asian specific genetic risk factor for sporadic Parkinson's disease. We generated two induced pluripotent stem cells (iPSCs), IBMS-iPSC-018-09 and IBMS-iPSC-020-01, from the peripheral blood mononuclear cells of two patients carrying LRRK2 p.G2385R variant by using the Sendai-virus delivery system. These iPSCs had a normal karyotype and exhibited pluripotency, such as an embryonic stem cell-like morphology, expression of pluripotent markers, and capacity to differentiate into three germ layers. This cellular model will provide a platform for pathophysiological studies of neurodegeneration in Parkinson's disease.

Abstract
Mitochondrial defects are associated with clinical manifestations from common diseases to rare genetic disorders. Myoclonus epilepsy associated with ragged-red fibers (MERRF) syndrome results from an A to G transition at nucleotide position 8344 in the tRNALys gene of mitochondrial DNA (mtDNA) and is characterized by myoclonus, myopathy and severe neurological symptoms. In this study, Sendai reprogramming method was used to generate an iPS cell line carrying the A8344G mutation of mtDNA from a MERRF patient. This patient-specific iPSC line expressed pluripotent stem cell markers, possessed normal karyotype, and displayed the capability to differentiate into mature cells in three germ layers.

Abstract
Sensorineural hearing loss (SNHL) is a prevalent form of deafness commonly arising from damage to the cochlear sensory hair cells and degeneration of the spiral ganglion neurons. In this study, Sendai virus was used to generate an induced pluripotent stem cell (iPSC) line from a 39-year-old female patient diagnosed with severe-to-profound, non-syndromic SNHL. The patient also carries a A1555G mutation in the mitochondrial 12S ribosome RNA gene (MTRNR1). This iPSC line was verified to express pluripotent markers, possess normal karyotype, harbor the specific mutation and demonstrated the capacity to differentiate into three germ layers.

Abstract
Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most prevalent monogenic kidney disorder leading to kidney failure. We generated induced pluripotent stem cells (iPSCs) from a 37-year-old man carrying a PKD1 Q533X mutation who suffered from kidney failure and a myocardial infarction. The iPSCs were reprogrammed from the patient's peripheral blood mononuclear cells using the Sendai virus system, and were confirmed to possess the specific PKD1 Q533X mutation and normal karyotype. Pluripotency was confirmed using in vitro and in vivo assays. This iPSC line will be useful for studying the mechanisms driving the complicated pathophysiology of ADPKD.

Abstract
Autosomal dominant polycystic kidney disease (ADPKD) is one of the most commonly inherited forms of polycystic kidney disease, and is characterized by the growth of numerous cysts in both kidneys. Here we generated an induced pluripotent stem cell (iPSC) line from the peripheral blood mononuclear cells (PBMCs) of a 63-year-old female ADPKD patient carrying an R803X mutation in the PKD2 gene using the Sendai-virus delivery system. Downstream characterization of these iPSCs showed that they possessed normal karyotyping, were free of genomic integration, retained the disease-causing PKD2 mutation, expressed pluripotency markers and could differentiate into three germ layers.

Abstract
Autosomal dominant polycystic kidney disease is one of the most prevalent forms of inherited cystic kidney disease, and can be characterized by kidney cyst formation and enlargement. Here we report the generation of a Type 1 ADPKD disease iPS cell line, IBMS-iPSC-012-12, which retains the conserved deletion of PKD1, normal karyotype and exhibits the properties of pluripotent stem cells such as ES-like morphology, expression of pluripotent markers and capacity to differentiate into all three germ layers. Our results show that we have successfully generated a patient-specific iPS cell line with a mutation in PKD1 for study of renal disease pathophysiology.

Abstract
Suspension cells can provide a source of cells for cellular reprogramming, but they are difficult to transfect by nonviral vectors. An efficient and safe nonviral vector (GO-Fe3 O4 -PEI complexes) based on iron oxide nanoparticle (Fe3 O4 )-decorated graphene oxide (GO) complexed with polyethylenimine (PEI) for the first time is developed for delivering three individual episomal plasmids (pCXLE-hOCT3/4-shp53, pCXLE-hSK, and pCXLE-hUL) encoding pluripotent-related factors of Oct3/4, shRNA against p53, Sox2, Klf4, L-Myc, and Lin28 into human peripheral blood mononuclear cells (PBMCs) simultaneously. The combined treatment of magnetic stirring and near-infrared (NIR)-laser irradiation, which can promote contact between the complexes and floating cells and increase the cell membrane permeability, respectively, is used to conduct multiple physical stimulations for suspension PBMCs transfection. The PCR analysis shows that the combinatorial effect of magnetic targeting and photothermal stimulation obviously promoted the transfection efficiency of suspension cells. The transfected cells show positive expression of the pluripotency markers, including Nanog, Oct4, and Sox2, and have potential to differentiate into mesoderm and ectoderm cells. The results demonstrate that the GO-Fe3 O4 -PEI complex provides a safe, convenient, and efficient tool for reprogramming PBMCs into partially induced pluripotent stem cells, which are able to rapidly transdifferentiate into mesodermal lineages without full reprogramming.

Abstract
Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disease caused by a trinucleotide repeat (CAG) expansion in the coding region of ATXN3 gene resulting in production of ataxin-3 with an elongated polyglutamine tract. Here, we generated induced pluripotent stem cells (iPSCs) from the peripheral blood mononuclear cells of a male patient with SCA3 by using the Sendai-virus delivery system. The resulting iPSCs had a normal karyotype, retained the disease-causing ATXN3 mutation, expressed pluripotent markers and could differentiate into the three germ layers. Potentially, the iPSCs could be a useful tool for the investigation of disease mechanisms of SCA3.

Abstract
The postresuscitative hemodynamic status of children with traumatic out-of-hospital cardiac arrest (OHCA) might be impacted by the early administration of epinephrine, but this topic has not been well addressed. The aim of this study was to analyze the early postresuscitative hemodynamics, survival, and neurologic outcome according to different time points of first epinephrine treatment among children with traumatic OHCA.Information on 388 children who presented to the emergency departments of 3 medical centers and who were treated with epinephrine for traumatic OHCA during the study period (2003-2012) was retrospectively collected. The early postresuscitative hemodynamic features (cardiac functions, end-organ perfusion, and consciousness), survival, and neurologic outcome according to different time points of first epinephrine treatment (early: <15, intermediate: 15-30, and late: >30 minutes after collapse) were analyzed.Among 165 children who achieved sustained return of spontaneous circulation, 38 children (9.8%) survived to discharge and 12 children (3.1%) had good neurologic outcomes. Early epinephrine increased the postresuscitative heart rate and blood pressure in the first 30 minutes, but ultimately impaired end-organ perfusion (decreased urine output and initial creatinine clearance) (all P < 0.05). Early epinephrine treatment increased the chance of achieving sustained return of spontaneous circulation, but did not increase the rates of survival and good neurologic outcome.Early epinephrine temporarily increased heart rate and blood pressure in the first 30 minutes of the postresuscitative period, but impaired end-organ perfusion. Most importantly, the rates of survival and good neurologic outcome were not significantly increased by early epinephrine administration.

Abstract
Gallbladder torsion is a rare, acute abdominal disease. It was first reported by Wendell in 1898. Since then, only 500 cases have been reported. Gallbladder torsion occurs in all age groups, although it usually appears in the latter stages of life. The occurrence ratio between women and men is 3:1. Most cases are diagnosed during surgery. The main treatment is surgical detorsion and cholecystectomy. Despite progress in radiologic imaging diagnosis, it is not easy to obtain a precise preoperative diagnosis of gallbladder torsion. In previous reports, only 9.8% of all gallbladder torsion cases were diagnosed preoperatively. We present a case of acute body-neck gallbladder torsion in an elderly man, and we review the radiologic findings of magnetic resonance imaging, computed tomography, and ultrasonography. The radiologic findings in the present case were helpful in obtaining a preoperative diagnosis of gallbladder torsion. The diagnosis was confirmed by T2-weighted magnetic resonance images, which showed an intra-gallbladder segment located between the body and neck of the gallbladder, with a notable crease within this segment.

Abstract
Human embryonic stem cells (hESCs), due to their self-renewal capacity and pluripotency, have become a potential source of transplantable β-cells for the treatment of diabetes. However, it is imperative that the derived cells fulfill the criteria for clinical treatment. In this study, we replaced common Matrigel with a synthetic peptide-acrylate surface (Synthemax) to expand undifferentiated hESCs and direct their differentiation in a defined and serum-free medium. We confirmed that the cells still expressed pluripotent markers, had the ability to differentiate into three germ layers, and maintained a normal karyotype after 10 passages of subculture. Next, we reported an efficient protocol for deriving nearly 86% definitive endoderm cells from hESCs under serum-free conditions. Moreover, we were able to obtain insulin-producing cells within 21 days following a simple three-step protocol. The results of immunocytochemical and quantitative gene expression analysis showed that the efficiency of induction was not significantly different between the Synthemax surface and the Matrigel-coated surface. Thus, we provided a totally defined condition from hESC culture to insulin-producing cell differentiation, and the derived cells could be a therapeutic resource for diabetic patients in the future.

Abstract
Down syndrome (DS), or Trisomy 21 (T21) syndrome, one of the most common chromosomal abnormalities, is caused by an extra duplication of chromosome 21. In studies of neuron development, experimental models based on human cells are considered to be the most desired and accurate for basic research. The generation of diseased induced pluripotetn stem (iPS) cell is a critical step in understanding the developmental stages of complex neuronal diseases. Here, we generated human DS iPS cell lines from second trimester amniotic fluid (AF) cells with T21 by co-expressing Yamanaka factors through lentiviral delivery and subsequently differentiated them into neuronal progenitor cells (NPCs) for further analyses. T21 AF-iPS cells were characterized for the expression of pluripotent markers and for their ability to differentiate into all three germ layers by forming embryoid bodies in vitro and teratomas in vivo. The T21 AF-iPS cells maintained their unique pattern of chromosomal karyotypes: three pairs of chromosome 21. The level of amyloid precursor protein was significantly increased in NPCs derived from T21 AF-iPS cells compared with NPCs from normal AF-iPS cells. The expression levels of miR-155 and miR-802 in T21 AF-iPS-NPCs were highly elevated in the presence of low expression of MeCP2. We observed that T21 iPS-NPCs generated fewer neurons compared with controls. T21 iPS-NPCs exhibit developmental defects during neurogenesis. Our findings suggest that T21 AF-iPS cells serve as a good source to further elucidate the impairment neurogenesis of DS and the onset of Alzheimer's disease.

Abstract
BACKGROUND & OBJECTIVES Paceilomyces farinosus is an entomogenous fungus with a powerful insecticidal activity against the larvae of Lipidoptera, Coleoptera and Hymenoptera. However, the hypoglycaemic activity of P. farinosus extract has not been studied. This study was undertaken to investigate the hypoglycaemic and anti-diabetic effects of P. farinosus (G30801) in rats with streptozotocin (STZ)-induced diabetes given a high-fat and compared with normal rats. METHODS Rats fed with high fat diet for 2 months and injected with (30 or 50 mg STZ/kg bw) showed raised level of plasma triglyceride (TG), cholesterol, D-glucose concentration and glycosylated haemoglobin (HbA1C) %. The STZ-induced type 1 (T1DM) and type 2 diabetes (T2DM) in rats was further confirmed using glucose tolerance test and insulin-glucose tolerance test. P. farinosus (G30801) was fermented in different media [soybean (S), black bean (B), and rice (R)] and their extracts were tested for hypoglycaemic effect using T1DM and T2DM rats. RESULTS STZ (30 and 50 mg/kg bw) could successfully induce T2DM and T1DM in rats, respectively. No change in blood glucose levels were noted in P. farinosus (R medium) treated normal rats (P < 0.05). In addition, STZ-high fat fed diabetic (T1DM and T2DM) rats when treated with P. farinosus (R medium) showed decreased blood glucose level as compared with P. farinosus extracted from B and S medium. CONCLUSIONS Our findings showed hypoglycaemic effect of fermented P. farinosus (G30801) in experimental diabetes rat model fed with high fat diet.

Abstract
Internal abdominal herniations are rare. A 34-year-old healthy man was seen in the emergency room because of severe lower abdominal pain and episodic vomiting. Pericecal internal herniation of the inferior ileocecal recess was suspected by abdominal CT study and confirmed by exploratory laparotomy. Finally, the herniated ileal loops were reduced, and the redundant peritoneum was resected. In the present case, CT demonstrates the precise anatomic diagnosis and shows acute complications that should be recommended preoperatively. Urgent surgical intervention is necessary to prevent strangulation, which is responsible for high mortality. Early diagnosis and treatment had a good outcome.
