Authors: Aires Alfredo , Dias Carla , Carvalho Rosa , Saavedra Maria José
Published: April 2017

The aim of this study was to evaluate the bioactivity of flavonoids extracted from sweet-cherry stems, which is often used by traditional medicine to treat infections from gastro-intestinal and urinary but without any consistent scientific evidences, moreover the information about the class of phenolics, their content and the potential bioactivity of such material is very scarce. Thus, in this context, we set a research study in which we evaluate the profile and content of phenolics extracted from sweet-cherry stems through a conventional (70ºC and 20 minutes) and ultrasound assisted extraction (40 kHz, room temperature and 20 minutes) methods. After, the extracts were phytochemical characterized by HPLC-DAD-UV/VIS, and assayed trough the in vitro minimum inhibitory concentration (MIC) bioassay, against Escherichia coli isolates. Simultaneously the total antioxidant activity were measured using the assay of 2,2′-azinobis-3-ethylbenzothiazoline-6-sulphonate (ABTS●+) radical cation. Our results showed that sweet-cherry stems presented higher content of sakuranetin, ferulic acid, p-coumaric acid, p-coumaroylquinic acid, chlorogenic acid and it´s isomer neochlorogenic acid. Their average levels were highly affected by the extraction method (p<0.001) used. The same trend was observed for total antioxidant activity and MIC values. The extracts produced under ultrasound presented both higher total antioxidant activity and lower minimum inhibitory concentration. The statistical analyses of our results showed a significant correlation (p<0.01) of total antioxidant activity and minimum inhibitory concentration with phenolics in the extracts studied. Thus, we can conclude that cherry stems can be further exploited to purify compounds and produced coproducts with enhanced biological added valuefor pharmaceutical industry.

Published: April 2017

The aim of this study was to expand our knowledge about anticancer activity of some polyamine derivatives with quinoline or chromane as terminal moieties. Tested compounds were evaluated in vitro towards metastatic human prostate adenocarcinoma (PC3), human carcinoma (DU145) and mammary gland adenocarcinoma (MCF7) cell lines. Cell viability was estimated on the basis of mitochondrial metabolic activity using watersoluble tetrazolium WST1 to establish effective concentrations of the tested compounds under experimental conditions. Cytotoxic potential of polyamine derivatives was determined by the measurement of lactate dehydrogenase activity released from damaged cells, changes in mitochondrial membrane potential, the cell cycle distribution analysis and apoptosis assay. It was revealed that the tested polyamine derivatives differed markedly in their antiproliferative activity. Bischromane derivative 5a exhibited a rather cytostatic than cytotoxic effect on the tested cells, whereas quinoline derivative 3a caused changes in cell membrane integrity, inhibited cell cycle progression, as well as induced apoptosis of prostate and breast cancer cells which suggest its potential application in cancer therapy.

Published: April 2017

Background: KAI-1/CD82 is a tumour suppressor gene; decreased gene expression is associated with the increased invasive ability of oral squamous cell carcinoma (OSCC), as hypothesised for various odontogenic cysts and tumours. p53 protein functions in the G1-S phase of the cell cycle to allow repair of the damaged DNA. In the present study, p53 and KAI-1 expression was investigated by using monoclonal antibodies in the various odontogenic cysts. Aims: To detect KAI-1 and p53 expression in radicular cysts, dentigerous cysts and odontogenic keratocysts (OKCs) and to assess the relation between p53 and KAI-1 expression in the aforementioned cysts. Materials and Methods: The present study included histopathologically diagnosed cases of radicular cysts, dentigerous cysts and OKCs for the expression of KAI-1 and p53 antibodies. Results: Amongst odontogenic cysts, radicular cysts expressed a maximum positivity of KAI-1 (20.92%) while p53 positive cells were maximum in odontogenic keratocysts (4.04%). The correlation between KAI-1 and p53 expression in the various odontogenic cysts was not found to be significant. Conclusion: The increased KAI-1 expression in the radicular cysts and its downregulation in OKCs may be indicative of aggressive clinical behaviour and the fact that OKCs are hypothesised as neoplastic rather than being developmental in origin.

Psychosocial elements of professionally-relevant behaviour in scrub nurses
Authors: Ribakova Anna , Deklava Liana , Circenis Kristaps , Millere Inga
Published: April 2017

The significance of professionally-relevant behaviour of scrub nurses for teamwork in the operating room is increasing, as proven by the studies carried out over the last decades worldwide. Non-technical skills include both social and cognitive elements. Specific behaviour evaluation system can be used to identify, assess and improve non-technical skills of scrub nurses. Improvement of non-technical skills helps reduce staff errors in the intraoperative period. The objective of the research is to find out whether there are statistically significant differences between scrub nursesâ€™ self-assessment of their non-technical skills, their implementation and surgeons' expectations. Demographic questionnaire, interview and Scrub Practitioners List of Intraoperative Non-technical Skills (SPLINT) were used in this study. Scrub nurses tend to engage in minimal communication and only a half of surgeons show expectations for exchange of thoughts and ideas from scrub nurses. This shows that the exchange of information between physicians and scrub nurses is generally insufficient. Surgical team members pay more attention to signals given by the surgical team and surgical process and rarely report on perception of signals given by medical equipment and a patient. Such data may be indicative of insufficient attention to a patientâ€™s safety during the surgery.

Social Media are mediae that allow users to meet online through the internet to communicate in social forum. To investigate the prevalence of social media networking, as it relates to academic achievement and psychological health of undergraduate students in federal universities in Nigeria, the study adopted a correlational survey research design. The study was carried out in federal universities in Nigeria. The population comprised all 28,120 undergraduates in the faculties of Education and Engineering in the 40 federal universities in Nigeria in 2015/2016 academic session. Simple and stratified random sampling techniques were used to draw a sample of 351 undergraduate students in 200 level in faculties of education and engineering in 4 sampled federal universities from 40 federal universities in Nigeria used for the study. Six research questions and four null hypotheses formulated guided the study. Strong reliability evidence was found for social media networking and psychological health scales which yielded 0.78 and 0.74 respectively. The instrument for data collection were well-structured interview schedule, self report questionnaire and students raw scores on a four point likert-type format which were administered to elicit information on studentsâ€™ social media networking, whilst an achievement test was administered to ascertain their academic achievement. Data for research questions 1 and 2 were answered using mean and standard deviation, whilst data for research questions 3-6 were analyzed using pearsonâ€™s r and R-square. The hypotheses were tested using Analysis of variance (ANOVA) statistic at 0.05 level of significance. It was found that studentsâ€™ social media networking significantly predicts their academic achievement and psychological health. Based on the findings, of this study, the researchers recommended among others that, the parents, peers and teachers should be on guard to ensure that these students use social networking for appropriate period or not and as well help these students to be aware of the negative effects.

Family which is the main trust of socialization is faced with many challenges in the contemporary world. Couples no longer fancy each other. Children are in constant struggle with parents. Many marriages are experiencing either divorce, separation or face off as a result of conflict. The present study deals primarily with causes, consequences and strategies in managing family conflict and how it applies to one’s understanding of emotion and struggling of power. The study made use of descriptive survey design. The sample of the study was 300 parents from different States of the Federation on Masters and Bachelor sandwich programme in the Department Educational Foundations who offers Sociology of Education in the Faculty of Education, University of Nigeria, Nsukka drawn through random sampling technique. A 54 item Strategies for Managing Family Conflict Questionnaire (SMFCQ) developed by the researchers was used for data collection. Data collected was analyzed using mean and standard deviation. Result indicated that infertility, financial difficulties, poor communication between family members, lack of sexual satisfaction/gratification can lead to conflict in the family. Family conflicts inflict people for the course of their life and prevent them from experiencing their full potential. It causes feeling of fear, of insecurity, rejection, and guilt which may lead to the development of ill-health, separation, divorce or even death. Strategies for dealing with conflict which such as focusing on the area of interest, striving to stay positive focusing on cooperation instead of control, approaching conflict with the aim to understand, resolve and respond are identified among others. It was recommended that conflict education be giving to couples at the period of courtship.Keywords: Family; conflict; Family conflict; Emotion and Power Struggles

Burnout and emotional experience in professional educators
Authors: Tschiesner Reinhard , Farnet Alessandra
Published: April 2017

Aim: This investigation deals with burnout processes and the associated emotional experience patterns in professional educators. The importance of emotions is underlined by the fact that emotions changes the readiness to act (Frijda, 1986). Each emotion is connected with certain kinds of behavior (e.g. disgust with reject of an object or fear with avoidance). Just burnout processes from the educatorsâ€™ emotional experience point of view become a significant role, because certain emotions are linked with the two most important stages in burnout processes, emotional exhaustion and depersonalization (Burisch, 2010). These aspects are able to become meaningful, because educators have to get in relation with learners and people. On account of these emotions have an effect on educational behavior processes. Method: A sample of nursery and primary school teachers as well as social educators were recruited and assessed with psychometric questionnaires (Maslach Burnout Inventory - MBI, Emotional Experience and Regulation Questionnaire - EER). Results: Data (N=148) evidences significant positive relations between emotional exhaustion and anxiety, grief, contempt, anger, guilt, shame as well as lifelessness and negative correlations between emotional exhaustion and interest. Significant positive correlations were calculated between depersonalization and shame, contempt, irritability, disgust and negative correlations between depersonalization and interest as well as happiness. Conclusions: Results indicate that consulting emotional experiences in burnout processes is useful: First results improve theoretical considerations concerning burnout models (e.g. Maslach & Jackson, 1981; Freudenberger & North, 1992) and second it can be helpful for explaining educatorsâ€™ behavior in burnout processes.

Are Dogs Fed a Kibble-Based Diet More Likely to Experience an Episode of Gastric Dilatation Volvulus Than Dogs Fed an Alternative Diet?
Authors: Buckley Louise Anne
Published: April 2017

Clinical bottom line:

Most of the studies that attempt to either partially or fully address the PICO contain limitations that mean that they should either be rejected as unable to address the PICO or viewed with caution due to potential bias in the population studied. Of the two studies that remain, the findings conflict. One study found dogs fed a diet containing small particles only (<5mm, mainly dry kibble fed dogs) at greater risk of GDV than those fed a diet containing large particles (>30mm, at least partly non-kibble based). The other study found no significant effect of kibble on GDV risk once other potential risk factors were controlled for in the analysis. Consequently, there is insufficient quality evidence to support the claim that feeding a kibble diet is associated with an increased risk of GDV. However, it is worth noting that no studies found that dogs fed a diet that contained no kibble (dry or moistened) were at increased risk of GDV, and the addition of either table scraps, canned food or non-kibble supplements to the dog’s diet reduced the risk in some studies but more research is needed to unpack the implications of this for feeding a kibble diet.

Published: April 2017

El presente estudio pretende definir y contrastar un modelo explicativo del consumo de alcohol, tabaco y uso problemático de videojuegos en función del autoconcepto y sus dimensiones en una muestra de estudiantes universitarios. Participaron 490 estudiantes de la provincia de Granada (España), con una edad comprendida entre los 20 y 29 años (M = 22,80 ± 3,63) y una distribución homogénea según su sexo. Los instrumentos empleados fueron el Cuestionario de Autoconcepto Forma-5 (García y Musitu, 1999), Test para la Identificación de Trastornos en el Uso de Alcohol (Saunders, Aasland, Babor, De la Fuente y Grant, 1993), Test para la Dependencia a la Nicotina (Heatherton, Kozlowski, Frecker y Fagerström, 1991) y el Cuestionario de Experiencias Relacionadas con Videojuegos (Chamarro et al., 2014). Se llevó a cabo un modelo de ecuaciones estructurales que se ajustó de forma adecuada (χ2 = 19,843; gl = 8; p = .011; CFI = .963 NFI = .943; IFI = .965; RMSEA = .055). Los resultados revelan una relación positiva entre el autoconcepto social y físico con el consumo de alcohol, y negativa entre la dimensión social y el uso de videojuegos. La dimensión académica se relacionó negativamente con el consumo de alcohol y el uso de videojuegos. Asimismo, el consumo de alcohol se relacionó positivamente con el consumo de tabaco y el uso de videojuegos. Se concluye que los niveles de autoconcepto pueden representar un factor de riesgo en el consumo de sustancias y el ocio digital de pantalla, siendo conveniente su estudio y consideración.
A Fast Motion Parameters Estimation Method Based on Cross-Correlation of Adjacent Echoes for Wideband LFM Radars
Authors: Zhang Yixiong , Hong Rujia , Yang Cheng-Fu , Zhang Yunjian , Deng Zhenmiao , Jin Sheng
Published: April 2017

In wideband radar systems, the performance of motion parameters estimation can significantly affect the performance of object detection and the quality of inverse synthetic aperture radar (ISAR) imaging. Although the traditional motion parameters estimation methods can reduce the range migration (RM) and Doppler frequency migration (DFM) effects in ISAR imaging, the computational complexity is high. In this paper, we propose a new fast non-searching motion parameters estimation method based on cross-correlation of adjacent echoes (CCAE) for wideband LFM signals. A cross-correlation operation is carried out for two adjacent echo signals, then the motion parameters can be calculated by estimating the frequency of the correlation result. The proposed CCAE method can be applied directly to the stretching system, which is commonly adopted in wideband radar systems. Simulational results demonstrate that the new method can achieve better estimation performances, with much lower computational cost, compared with existing methods. The experimental results on real radar data sets are also evaluated to verify the effectiveness and superiority of the proposed method compared to the state-of-the-art existing methods.
A Fast K-prototypes Algorithm Using Partial Distance Computation
Authors: KIM Byoungwook
Published: April 2017

The k-means is one of the most popular and widely used clustering algorithm, however, it is limited to only numeric data. The k-prototypes algorithm is one of the famous algorithms for dealing with both numeric and categorical data. However, there have been no studies to accelerate k-prototypes algorithm. In this paper, we propose a new fast k-prototypes algorithm that gives the same answer as original k-prototypes. The proposed algorithm avoids distance computations using partial distance computation. Our k-prototypes algorithm finds minimum distance without distance computations of all attributes between an object and a cluster center, which allows it to reduce time complexity. A partial distance computation uses a fact that a value of the maximum difference between two categorical attributes is 1 during distance computations. If data objects have m categorical attributes, maximum difference of categorical attributes between an object and a cluster center is m. Our algorithm first computes distance with only numeric attributes. If a difference of the minimum distance and the second smallest with numeric attributes is higher than m, we can find minimum distance between an object and a cluster center without distance computations of categorical attributes. The experimental shows proposed k-prototypes algorithm improves computational performance than original k-prototypes algorithm in our dataset.

[abstFig src='/00290002/09.jpg' width='300' text='Standard Lifilm configuration' ] In this study, we propose an excretion detection system, Lifi, which does not require sensors inside diapers, and we verify its capabilities. It consists of a sheet with strategically placed air intakes, a set of gas sensors, and a processing unit with a newly developed excretion detection algorithm. The gas sensor detects chemicals with odor in the excrement, such as hydrogen sulfide and urea. The time-series data from the gas sensor was used for the detection of not only excretion, but also of the presence/absence of the cared person on the bed. We examined two algorithms, one with a simple threshold and another based on the clustering of sensor data, obtained using thek-means method. The results from both algorithms were satisfactory and similar, once the algorithms were customized for each cared person. However, we adopted the clustering algorithm because it possesses a higher level of flexibility that can be explored and exploited. Lifi was conceived from an overwhelming and serious desire of caretakers to discover the excretion of bed-ridden cared persons, without opening their diapers. We believe that Lifi, along with the clustering algorithm, can help caretakers in this regard.
A Comparative Electrochemical Behaviour Study of p-nitrophenol Using GC and Pt Electrode
Authors: Gupta Sangita
Published: April 2017

The work reports a comparative electrochemical behavior study of p-nitrophenol using GC and Pt electrode.  For this purpose, Cyclic Voltammetry was employed, where the redox mechanisms could be compared for reduction processes of p-nitrophenol by analysis of the voltammetric responses. Voltammetric curves of p-nitrophenol in aqueous-methanol medium on different pH using B.R. buffer for various concentrations (0.05mM, 0.1 mM, 0.15mM, 0.2mM) and scan rates at GC and Pt electrode was obtained. The very complicated reduction of p-nitrophenol revealed three reduction peaks out of which two peaks are irreversible and one peak is reversible.

Equation 1

HOC6H4NO2     +    e-                                            HOC6H4NO2∙-

Equation 2

HOC6H4NO2∙- +  HOC6H4NO2        HOC6H4NO2H.   +  -OC6H4NO2

Equation 3

HOC6H4NO2H.             +  HOC6H4NO2∙-              HOC6H4NO2H-  +   HOC6H4NO2

Equation4

HOC6H4NO2H-             +  HOC6H4NO2                HOC6H4NO       +  -OC6H4NO2 +H2O         

The result obtained from GC electrode proved to be better than Pt electrode. Hence the GC electrode can be considered a suitable tool for determination of redox mechanism of  p-nitrophenol.

Published: April 2017

This study tests the random walk theory in the Nigerian stock market by analyzing whether stock returns follow a random walk distribution. The study employs the daily returns of the Top 20 most performing stocks on the NSE for the period January 1st 2010 to December 31st 2014. Autocorrelation and runs test were employed for hypothesis testing.  Based on our analysis, we found that the daily stock returns of the 20 most active stocks on the Nigerian stock market are randomly distributed indicating that Nigerian Stock market is informational efficient at the weak form level. The implication of the finding is that no one can fool the market consistently for a long time by trading on the basis of past information such as historical stock prices. The study recommends that more efforts should be made to reposition the market to attract more investible funds from domestic and foreign investors.
Role of Banks in Ensuring a Sustainable and Inclusive Growth
Authors: Agarwal Saurabh
Published: April 2017

Economic growth in India has to be inclusive in order to make it sustainable. Inclusiveness is an essential element in a democracy. If policies that bring about economic growth do not benefit the people in a wide and inclusive manner, they will not be sustainable. Equally, inclusive growth is essential to grow the market size, which alone will sustain growth momentum. Inclusive growth is the only just and equitable way that any society can grow. Financial Inclusion rests on three pillars viz. access to financial services, affordability of such services and actual utilization of such services. Financial Inclusion can be achieved only if all the three pillars show affirmative results. It may prove to be very useful for the banking Industry and the overall Indian economy. It will be useful for policy makers, academicians and researchers in the field.

Pseudodiaptomus marinus was initially discovered at the end of September 2016 in a sample taken during a long-term plankton survey of Sevastopol Bay started in 2002. We found 6 females and 12 copepodites (I-V stages) of P. marinus at the center of Sevastopol Bay (St. 3) on September 22. At the mouth of Bay (St. 2) the species was not found. Both females and copepodite stages I-V of P. marinus were found at the both stations on November 11. Abundance of P. marinus increased to 1236 individuals in sample (1373 ind/m3) at the center of the bay. Moreover, two individuals of P. marinus nauplii identified by Sazhina, were found in this sample. At the mouth of the bay abundance of the invasive species reached 103 individuals in sample (103 ind/m3). It is considered to be native to the Northwestern Pacific Ocean, but now species is widespread across the world. Brilinski described in details its distribution in the World's oceans. Recently P. marinus has been found in the Atlantic Ocean in the North Sea and in the Mediterranean Sea. P. marinus is a typical estuarine coastal copepod, living in shallow eutrophic inshore waters. It is tolerant to a wide range of salinity (2.5-35 ptt) and temperature (5-28 ºC) and has the highest invasive potential. Thus species is adapted to relatively low salinities and low winter temperatures of the Black Sea. Copepodite stages at both stations indicate the existence of reproducing populations. Thus, very likely P. marinus is the new established species in coastal area of the Black Sea. As other recent pelagic invaders – the copepods Acartia tonsa Dana 1849, Oithona davisae Ferrari F. D. & Orsi 1984; ctenophores Mnemiopsis leidyi A. Agassiz, 1865 and Beroe ovata Bruguiere, 1789 - P. marinus was most probably brought into Sevastopol Bay in the ballast water of ships. Long-term studies at basin scale are needed to estimate the structural changes in the Black Sea zooplankton community.

Актуальность изучения экологических и поведенческих адаптаций гидрофильных птиц в городских зонах Крыма обусловлена необходимостью сохранения биоразнообразия в условиях антропогенного преобразования внутренних водоёмов и морских берегов полуострова. Целью исследования было выявление условий, определяющих эффективность размножения волчков в биотопе с высокой антропогенной нагрузкой; задачами исследования — определение пищевого спектра, поведенческих реакций и сроков пребывания птиц в биотопе. Впервые в городской зоне черноморского побережья Крыма (бухта Круглая, Севастополь) зарегистрировано гнездование малой выпи (волчка) Ixobrychus minutus (Linnaeus, 1766). Визуальное наблюдение, фото- и видеосъёмку проводили не менее пяти раз в неделю. Пару взрослых особей наблюдали с 3 июля до 2 августа, трёх молодых особей — с 24 июля до 7 сентября 2016 г. в вершине бухты. Успешному размножению волчков способствовали наличие естественных укрытий (зарослей тростника) и хорошая кормовая база. Основной добычей птиц была молодь кефалей, также отмечены случаи поимки глазчатой зеленушки, морской собачки-павлина и различных беспозвоночных. Птицы проявляли нетипичное для своего вида синантропное поведение. Результаты исследования свидетельствуют о достаточно высоком адаптивном потенциале волчка к различным факторам беспокойства в городской зоне черноморского побережья Крыма. Предполагается возможность «возвратной урбанизации» волчка — заселения им исходных местообитаний (зарослей околоводной растительности в вершинах некоторых бухт городской зоны Крыма).

Psoriasis is a chronic inflammatory skin disorder characterized by rapid proliferation of keratinocytes and incomplete keratinization. Discovery of safer and more effective anti-psoriatic drugs remains an area of active research at the present time. A431 and B16-F10 cell lines were used as in vitro models. In the present study, we aimed at assessing the Anti-psoriatic activity of aqueous extract of Acalypha indica. We analyzed the efficiency of A. indica leaf extract in inducing cell death and apoptosis in these cell lines. The cell death (Propidium iodide) and apoptosis (Annexin V) was assessed by fluorescence studies and we observed 80% of cell death and 75% of apoptosis in both cell lines. Therefore, this in vitro study suggested that the leaf extract is capable of serving as anti-psoriasis agent or compound.

Published: April 2017

Copepods are the most abundant metazoan zooplankton amongst multicellular animals. The present study was performed to establish the sequence variation of partial mitochondrial Cytochrome c Oxidase I gene (COI) from Mesocyclops leuckarti collected from the Retteri Lake, Chennai in order to identify and describe their genetic divergence along with the phylogenetic relatedness with other species. DNA of individual M. leuckarti was extracted and the partial mitochondrial COI gene was successfully amplified using the universal primers LCO-1490 and HCO-2198. A 576bp partial mitochondrial COI gene sequence was obtained. Analysis of partial COI sequences of M. leuckarti exposed 93% similarity amongst all the individual of copepods selected from Genbank. The obtained COI sequences of Cyclopoid copepod was confirmed with BLAST analysis. Phylogenetic analysis of M. leuckarti along with selected out groups from different taxa level further supports the clarity and maintained the authentic of taxonomy up to the subclass level: Copepoda. The results showed that, the COI barcoding of cyclopoid copepod species could be distinguished from the others very clearly. Thus, it strongly indicated that COI may be a useful construction of a comprehensive DNA barcode database for copepods inhabiting the freshwater bodies in Chennai.

Several evaluation systems for clinical exams have been suggested over the years, but no systematic analysis of checklists or criteria‐based exam forms has yet been undertaken. The aims of this study were to analyze criteria‐based evaluation forms and to identify areas in the teaching process potentially requiring improvements. All evaluation forms introduced in 2012 at the Clinic for Periodontology, Endodontology, and Cariology at the University Center of Dental Medicine in Basel, Switzerland, and applied over a three‐year period (n=1,093 in 2015) were analyzed using predefined criteria. The authors investigated how well clinical tasks were examined with the given criteria and which criteria were preferably evaluated with a grading system (0–2) or a yes/no choice. The average final grades ranged from 0.89 (n=92) for gold inlay preparation to 1.76 (n=46) for periodontal treatment. Comments were made in 38.5% (n=356) of all exams, mainly highlighting specific aspects of existing criteria. Overall, 13 criteria out of 66 should be checked instead of graded. This methodological analysis of exam forms assessing tasks in operative dentistry yielded valuable information on areas with potential for improvement in the dental curriculum and the evaluation process. Aspects that require more theoretical background and/or hands‐on recommendations from experienced clinicians were identified, and ways of further refining and redesigning the evaluation forms were proposed.

Hepatic FAM3A expression is repressed under obese conditions, but the underlying mechanism remains unknown. This study determined the role and mechanism of miR-423-5p in hepatic glucose and lipid metabolism by repressing FAM3A expression. miR-423-5p expression was increased in the livers of obese diabetic mice and in patients with nonalcoholic fatty liver disease (NAFLD) with decreased FAM3A expression. miR-423-5p directly targeted FAM3A mRNA to repress its expression and the FAM3A-ATP-Akt pathway in cultured hepatocytes. Hepatic miR-423-5p inhibition suppressed gluconeogenesis and improved insulin resistance, hyperglycemia, and fatty liver in obese diabetic mice. In contrast, hepatic miR-423-5p overexpression promoted gluconeogenesis and hyperglycemia and increased lipid deposition in normal mice. miR-423-5p inhibition activated the FAM3A-ATP-Akt pathway and repressed gluconeogenic and lipogenic gene expression in diabetic mouse livers. The miR-423 precursor gene was further shown to be a target gene of NFE2, which induced miR-423-5p expression to repress the FAM3A-ATP-Akt pathway in cultured hepatocytes. Hepatic NFE2 overexpression upregulated miR-423-5p to repress the FAM3A-ATP-Akt pathway, promoting gluconeogenesis and lipid deposition and causing hyperglycemia in normal mice. In conclusion, under the obese condition, activation of the hepatic NFE2/miR-423-5p axis plays important roles in the progression of type 2 diabetes and NAFLD by repressing the FAM3A-ATP-Akt signaling pathway.
