Capitalizing on strengths and minimizing weaknesses of veterans in civilian employment interviews: Perceptions of interviewers and veteran interviewees.

Like all job applicants, veterans have to face the ubiquitous employment interview and pass this potential hurdle to civilian sector employment. So, because of the uniqueness of transitioning from the military to civilian employment, the present paper sought to identify perceived interviewing strengths and weaknesses of veteran interviewees from (a) the perspective of civilian sector human resource professionals (i.e. hiring personnel) with experience interviewing veterans (Study 1, five focus groups, N = 14), and (b) veterans (Study 2, N = 93). Qualitative analysis of the focus group transcripts resulted in the emergence of two theme categories: (1) veteran interviewee strengths and (2) veteran interviewee weaknesses. This information guided the development of a 10-item survey that was completed by 93 veterans (Study 2). In its totality, the results (from both Study 1 and Study 2) indicated that communication of soft skills, confidence, and professionalism were perceived to be strengths that veterans displayed during civilian employment interviews, and conversely, the ineffective translation and communication of relevant technical skills acquired in the military, use of military jargon, and nervousness were considered to be weaknesses. Recommendations to capitalize on the strengths and mitigate the weaknesses are presented.

Estimating the Effect of Genital vs Extragenital Warts on Immunocompetent Indian Adult Patients; Quality of Life: A Comparative Cross-Sectional Study.

Introduction: Extragenital warts, often known as EGWs, affect between 7% and 10% of the population. Despite the plethora of research on the impact of genital warts (GWs) on "Quality Of Life", EGWs have received little attention. The purpose of this study was to conduct a cross-sectional investigation with the objective of contrasting the effects of GWs and EGWs on the health-related quality of life and other characteristics. Participants and Procedures: A cross-sectional clinical study was piloted at a tertiary care center. Participants in the study included two groups of healthy adults, each group consisting of 100 adult subjects. Those diagnosed with EGWs were included in group A, while patients diagnosed with GWs made up group B. The "Dermatology Life Quality Index" questionnaire was used to evaluate various parameters. Observations were compared for significance. Results: The majority of the subjects in both the groups were observed to have less than 10 warts. The Dermatology Life Quality Index score for the EGWs had an average of 8.66 ± 2.31 score; GWs had an average of 5.12 ± 3.25. This mean variance was statistically significant. The level of the dissatisfaction was highly significantly different among the groups and the subjects being more in the EGW group dissatisfied. Conclusion: The findings of this investigation indicate that EGWs have a significant and detrimental effect on the Quality Of Life. Medical experts must teach people how to prevent the disease's spread and recurrence due to its persistence. They must also consider the psychological and societal repercussions of the disease while discussing therapy choices.

Assessment of Right Ventricular Function by Strain Imaging in Patients Presenting with Acute Myocardial Infarction: An Original Research.

Objective: This study sought to determine the relationship between right ventricular (RV) function and clinical variables and prognosis in individuals with acute myocardial infarction (AMI) utilizing strain imaging. Materials and Methods: A prospective observational research involving 150 patients who had been admitted with AMI was carried out. Utilizing two-dimensional speckle-tracking strain imaging, RV function was assessed. Age, sex, risk factors, and comorbidities were recorded as clinical parameters. A 12-month follow-up was conducted to assess major adverse cardiovascular events (MACE). Results: 65% of the study's participants were men, with a mean age of 58.2 years. When compared to a healthy control group, individuals with AMI had significantly lower RV longitudinal strain (RVLS) (P 0.001). RVLS and left ventricular ejection fraction had a statistically significant connection (r = 0.642, P 0.001). Patients with compromised RVLS had a greater rate of MACE over the follow-up period compared to those with maintained RV function (P = 0.014). Conclusion: In conclusion, strain imaging offers useful information for evaluating RV function in patients with AMI. Reduced left ventricular performance and a higher likelihood of unfavorable clinical outcomes are linked to impaired RVLS. Utilizing strain imaging to detect RV dysfunction early can help direct treatment plans and enhance patient outcomes.

ZBTB12 is a molecular barrier to dedifferentiation in human pluripotent stem cells.

Development is generally viewed as one-way traffic of cell state transition from primitive to developmentally advanced states. However, molecular mechanisms that ensure the unidirectional transition of cell fates remain largely unknown. Through exact transcription start site mapping, we report an evolutionarily conserved BTB domain-containing zinc finger protein, ZBTB12, as a molecular barrier for dedifferentiation of human pluripotent stem cells (hPSCs). Single-cell RNA sequencing reveals that ZBTB12 is essential for three germ layer differentiation by blocking hPSC dedifferentiation. Mechanistically, ZBTB12 fine-tunes the expression of human endogenous retrovirus H (HERVH), a primate-specific retrotransposon, and targets specific transcripts that utilize HERVH as a regulatory element. In particular, the downregulation of HERVH-overlapping long non-coding RNAs (lncRNAs) by ZBTB12 is necessary for a successful exit from a pluripotent state and lineage derivation. Overall, we identify ZBTB12 as a molecular barrier that safeguards the unidirectional transition of metastable stem cell fates toward developmentally advanced states.

Pattern of Adverse Drug Reactions among Pregnant Women and Pediatric Patients in a Tertiary Care Hospital.

BACKGROUND: Adverse drug reactions (ADRs) among pregnant women and pediatric patients are a significant public health concern. ADRs monitoring and documentation are considered essential practices to decrease the chances of ADRs and ensure the safe use of drugs. OBJECTIVE: Therefore, the study was designed to evaluate the pattern of adverse drug reactions among pregnant women and pediatric patients in a tertiary care hospital. METHODS: The study was conducted at Kalpana Chawla Government Medical College and Hospital, Karnal, Haryana, for a period of 2 years. During this period, ADRs reported by the healthcare professionals of gynecology and pediatric department to the ADRs monitoring centre of our institute were included in the study. RESULTS: Out of 54 total ADRs, 40 ADRs occurred among pregnant women, and 14 ADRs were reported in pediatric patients. The majority of the ADRs were observed in the age group of 21-30 years (pregnant women) and 3-5 years (pediatric patients). Antibiotics were most commonly implicated in ADRs among pregnant women (60%) and pediatric patients (79%). In our study, the dermatological system was mostly affected among pregnant women and pediatric patients. Urticaria, contact dermatitis, and erythematous rash were the most commonly reported ADRs among pregnant women and pediatric patients. CONCLUSION: Over-prescribing and irrational use of antibiotics make these vulnerable populations more susceptible to ADRs and antibiotic resistance. Therefore, there is a need to create awareness among health care professionals regarding the spontaneous reporting of ADRs for ensuring drug safety and reducing morbidity and mortality among pregnant women and pediatric patients.

Assessment of cardiac function in children by strain imaging and its correlation with conventional echocardiographic parameter.

Background: The objectives of this study were to find out of normal reference value for age-dependent longitudinal strain values in children and find its correlation with conventional echocardiographic parameters. Methods: In total, 100 healthy normal children aged between 2 and 15 years were enrolled and divided into three age groups, namely, 2-5 years, 5-10 years, and 10-15 years. Using the GE Vivid 7 ultrasound platform with 4 or 7 MHz probes, both LV and RV global longitudinal strains and conventional echocardiographic parameters were acquired. Results: In normal healthy children, left ventricular GLS values were -20.10 to -19.68 (mean: -19.89), -21.93 to -21.02 (mean: -21.48), and -20.87 to -20.41 (mean: -20.64)) in children aged 2-5 years, 5-10 years, and 10-15 years and right ventricular GLS values were -16.80 to -16.44 (mean: -16.62), -27.85 to -27.27 (mean: -27.56), -28.44 to -27.93 (mean: -28.19) in the above three groups, respectively. No significant increase was noted in the left ventricular strain value from basal to the apical segment from age group 2 years to 15 years and no gender differences were seen. None of the conventional echocardiographic parameters commonly used to assess the left or right ventricular systolic function had a significant correlation with LVGLS and RVGLS. Conclusions: The mean LVGLS values were -19.89, -21.48, and -20.64 and RVGLS were -16.62, -27.56, and -28.19 in healthy normal children aged 2-5 years, 5-10 years, and 10-15 years, respectively, and conventional echocardiographic parameters did not have any significant correlation with these values.

Exploring the acceptance for e-learning among higher education students in India: combining technology acceptance model with external variables.

The concept of e-learning has now become fundamental in student learning process. This concept becomes even more relevant in situations of global crisis such as that arising from COVID-19. Since this pandemic there have been tectonic shifts in the education sector. Effective implementation of e-learning in higher education depends on students' adoption of this technology. So, this study aimed to identify the factors influencing the behavioral intentions and actual usage of students in adopting e-learning. Additionally, it also examined the mediation effects among different latent constructs. Based on technology acceptance model (TAM), an explanatory structural model of technology acceptance was tested along with introduction of three external variables. To do this, a quantitative investigation was conducted using an online survey of higher education students in India, obtaining 570 responses. The structural model was examined through the partial least square structural equation modeling. Results obtained make it possible to validate the proposed model as findings explains the 56.2% variance of actual usage. In addition, it shows the direct and indirect effect of all three selected external variables of personal innovativeness, social factors and self-efficacy on the main constructs of TAM. The findings of this study are relevant for the higher education management, administration, e-learning system developers, marketers and researchers for improving the effective usage of e-learning by developing more focused and customized learning solutions.

Reactivity and Mechanisms of Photoactivated Heterometallic [RuII NiII ] and [RuII NiII RuII ] Catalysts for Dihydrogen Generation from Water.

Two heterometallic photocatalysts were designed and probed for water reduction. Both [(bpy)2 RuII NiII (L1 )](ClO4 )2 (1) and [(bpy)2 RuII NiII (L2 )2 RuII (bpy)2 ](ClO4 )2 (2) can generate the low-valent precursor involved in hydride formation prior to dihydrogen generation. However, while the bimetallic [RuII NiII ] (1) requires the presence of an external photosensitizer to trigger catalytic activity, the trimetallic [RuII NiII RuII ] (2) displays significant coupling between the catalytic and light-harvesting units to promote intramolecular multielectron transfer and perform photocatalysis at the Ni center. A concerted experimental and theoretical effort proposes mechanisms to explain why 1 is unable to achieve self-supported catalysis, while 2 is fully photocatalytic.

Impact of Climatic Variations on Drug-induced Skin Reactions in Two Different Regions of India.

BACKGROUND: Around 2-3% of hospitalizations have been reported due to dermatological adverse drug reactions. Recent studies suggest that climatic variations affect the skin barrier function and extreme conditions aggravate skin disorders. OBJECTIVE: The present study was designed to compare the impact of climatic variations on drug-induced skin reactions in the Northern and Eastern regions of India. METHODS: We performed a one-year retrospective study to evaluate the impact of climatic variations (temperature and humidity) on drug-induced skin reactions in the Eastern (Kalyani, West Bengal) and Northern (Karnal, Haryana) regions. Drug-induced skin reactions were reported month-- wise in both the Eastern and Northern regions. Temperature and humidity levels were also noted month-wise in both regions. The direct correlation between climatic variations and the number of drug reactions were assessed using Pearson's correlation and quadratic regression analysis. RESULTS AND DISCUSSION: Overall, 99 and 81 dermatological adverse drug reactions were reported in tertiary care hospitals in the Northern and Eastern regions, respectively. During the summer season, the humidity level was found to be low in the Northern region as compared to the Eastern region. During this period, drug-induced skin reactions were reported significantly (p<0.05) more in the Northern region as compared to the Eastern region. Furthermore, quadratic regression analysis revealed that climatic variations contributed to drug reaction variability in the Northern region (68.5%) and Eastern region (23.5%). CONCLUSION: Therefore, the difference in the prevalence of drug-induced skin reactions may be related to the different climatic conditions among these two regions. Further studies in controlled climatic conditions should be performed for definitive correlations and to look into possible solutions.

Efficacy of Spironolactone in Adult Acne in Polycystic Ovary Syndrome Patients an Original Research.

INTRODUCTION: This prospective clinical trial was designed to assess the effects of a long-term therapy with spironolactone, with and without dietary-induced weight-loss, on clinical features, lipid profile, and insulin levels in women with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS: Twenty-five patients (range of age 16-32 year; 13 lean and 12 overweight) fulfilling formal diagnostic criteria for PCOS (oligomenorrhea and/or amenorrhea, biochemical and/or clinical evidence of hyperadrogenism) were studied at baseline and then received oral spironolactone (100 mg/die) for 12 months; association with lifestyle modifications was recommended to all overweight patients. Clinical, endocrine, and metabolic parameters (oral glucose tolerance test [OGTT], lipid profile) were measured at baseline and at the end of the antiandrogen treatment. RESULTS: The therapy was associated with a significant average decline of triglycerides in overweight subjects and with increased high-density lipoprotein-cholesterol levels in lean patients. The insulin levels at 60 min during OGTT, homeostasis model assessment-insulin resistance and area under curve of insulin were significantly lowered in overweight women after 12 months of spironolactone and weight loss and no negative changes in insulin secretion and sensitivity were observed in PCOS women after pharmacological treatment alone. CONCLUSION: The efficacy of spironolactone on the androgenic clinical aspects of PCOS has been confirmed in this study. Furthermore, our data show that long-term treatment with spironolactone exerts no negative effects on lipoprotein profile and glucose metabolism; more relevant beneficial effects on glucose and lipid metabolism were observed when the antiandrogen was associated with weight loss in overweight PCOS women.

Chrysin rescues rat myocardium from ischemia-reperfusion injury via PPAR-γ/Nrf2 activation.

Pharmacological strategies aimed at co-activating peroxisome proliferator-activated receptor-gamma (PPAR-γ)/nuclear factor erythroid 2-related factor 2 (Nrf2) pathway have shown promising results in alleviating myocardial injury. The aim of the study was to evaluate the role of chrysin, a PPAR-γ agonist, in ischemia-reperfusion (IR)-induced myocardial infarction (MI) in rats and to explore the molecular mechanism driving this activity. To evaluate this hypothesis, chrysin (60 mg/kg, orally), PPAR-γ antagonist (GW9662, 1 mg/kg, intraperitoneally), or both were administered to rats for 28 days. On the 29th day, one-stage ligation of left anterior descending coronary artery for 45 min followed by 60 min of reperfusion was performed. Chrysin significantly decreased infarct size and improved cardiac functions following IR-induced MI. This improvement was corroborated by augmented PPAR-γ/Nrf2 expression as confirmed by immunohistochemistry and western blotting analysis. Chrysin exhibited strong anti-oxidant property as demonstrated by increased GSH and CAT levels and decreased 8-OHdG and TBARS levels. Our findings also imply that chrysin significantly inhibited inflammatory response as validated by decreased NF-κB, IKK-ß, CRP, TNF-α and MPO levels. In addition, chrysin decreased TUNEL/DAPI positivity, a marker of apoptotic response and normalized cardiac injury markers. The histopathological and ultrastructural analysis further supported the functional and biochemical outcomes, showing preserved myocardial architecture. Intriguingly, co-administration with GW9662 significantly diminished the cardioprotective effect of chrysin as demonstrated by depressed myocardial function, decreased PPAR-γ/Nrf2 expression and increased oxidative stress. In conclusion, the present study demonstrates that co-activation of PPAR-γ/Nrf2 by chrysin may be crucial for its cardioprotective effect.

Development of hierarchical magnesium oxide anchored cerium oxide nanocomposites with improved magnetic properties and photocatalytic performance.

A facile strategy was introduced for the development of pure MgO and its nanocomposites using different CeO2 contents (3%-7%) to enhance their magnetic properties and photocatalytic performance. Different morphologies (namely nanoflowers and rhombohedral type nanostructures) were obtained using an in situ hydrothermal method at different concentrations of CeO2. X-ray diffraction results revealed that peaks of CeO2 were observed along with peaks of MgO, which confirms the presence of both phases. The crystallite size and particle size were found to increase with changing CeO2 content in the host matrix of MgO. Moreover, the band gap reduces while the magnetic character increases with CeO2 content. The magnetic behaviour of the nanocomposites was elucidated on the basis of oxygen intrinsic defects, which are shown through XPS. EPR measurements were carried out to understand the valence electrons and establish the defects present in the material, which are related to the size of the nanostructures. The degradation of Rose Bengal dye was performed to probe the photocatalytic activity of the MgO@CeO2 nanocomposites. Hence the facile synthesis of these nanostructures conveyed good magnetic properties along with its application towards dye degradation.

Assessment of metal contamination and the associated human health risk from dustfall deposition: a study in a mid-sized town in India.

It is evident from the past studies that dust fallout is a severe concern due to its impact to urban air quality and public health. This study mainly examines the spatial and seasonal variation of dustfall at ambient levels and chemical characterization of its insoluble fraction for Kharagpur Town, India. Dustfall samples were collected monthly for 1 year (July 2014 to June 2015) from four sampling sites. The results showed that the maximum dustfall deposition is found during summer (March to June) and in the range of 2.01 ± 0.36 to 15.74 ± 3.83 ton km-2 month-1, and minimum deposition is during monsoon season (July to October) in the range of 0.42 ± 0.72 to 7.38 ± 5.8 ton km-2 month-1. Selected metals like Sc, V, Cr, Co, Ni, Zn, Y, Zr, Ce, Hf, and Pb were analyzed using the high-resolution inductively coupled mass spectrometer (HR-ICP-MS) technique, and the contamination level of heavy metals was assessed using the geoaccumulation index (Igeo) and enrichment factor (EF). To estimate the sources for the metallic contaminants, principal component analysis (PCA) was conducted. The US EPA health risk assessment model was applied to determine the hazard index and hazard quotient values. The results show the significant level of enrichment for Pb (EF = 41.79) and Cr (EF = 4.39). The Igeo values point out moderate contamination by Pb (Igeo = 2.01) and Cr (Igeo = 1.6) in Kharagpur Town. This study suggests that in the context of noncancer risk of heavy metals as determined by the hazard index (HI) and hazard quotient (HQ) values, ingestion is the main source of exposure to dust in adults and children followed by dermal contact. Considering the inhalation route, carcinogenic risk level of Cr, Co, and Ni for adults and children is lower than the EPA's safe limit (10-6 to 10-4), indicating that cancer risk of these metals due to exposure to dustfall in Kharagpur is negligible.

Regulation of cell-type-specific transcriptomes by microRNA networks during human brain development.

MicroRNAs (miRNAs) regulate many cellular events during brain development by interacting with hundreds of mRNA transcripts. However, miRNAs operate nonuniformly upon the transcriptional profile with an as yet unknown logic. Shortcomings in defining miRNA-mRNA networks include limited knowledge of in vivo miRNA targets and their abundance in single cells. By combining multiple complementary approaches, high-throughput sequencing of RNA isolated by cross-linking immunoprecipitation with an antibody to AGO2 (AGO2-HITS-CLIP), single-cell profiling and computational analyses using bipartite and coexpression networks, we show that miRNA-mRNA interactions operate as functional modules that often correspond to cell-type identities and undergo dynamic transitions during brain development. These networks are highly dynamic during development and over the course of evolution. One such interaction is between radial-glia-enriched ORC4 and miR-2115, a great-ape-specific miRNA, which appears to control radial glia proliferation rates during human brain development.

Febuxostat Modulates MAPK/NF-κBp65/TNF-α Signaling in Cardiac Ischemia-Reperfusion Injury.

Xanthine oxidase and xanthine dehydrogenase have been implicated in producing myocardial damage following reperfusion of an occluded coronary artery. We investigated and compared the effect of febuxostat and allopurinol in an experimental model of ischemia-reperfusion (IR) injury with a focus on the signaling pathways involved. Male Wistar rats were orally administered vehicle (CMC) once daily (sham and IR + control), febuxostat (10 mg/kg/day; FEB10 + IR), or allopurinol (100 mg/kg/day; ALL100 + IR) for 14 days. On the 15th day, the IR-control and treatment groups were subjected to one-stage left anterior descending (LAD) coronary artery ligation for 45 minutes followed by a 60-minute reperfusion. Febuxostat and allopurinol pretreatment significantly improved cardiac function and maintained morphological alterations. They also attenuated oxidative stress and apoptosis by suppressing the expression of proapoptotic proteins (Bax and caspase-3), reducing TUNEL-positive cells, and increasing the level of antiapoptotic proteins (Bcl-2). The MAPK-based molecular mechanism revealed suppression of active JNK and p38 proteins concomitant with the rise in ERK1/ERK2, a prosurvival kinase. Additionally, a reduction in the level of inflammatory markers (TNF-α, IL-6, and NF-κB) was also observed. The changes observed with febuxostat were remarkable in comparison with those observed with allopurinol. Febuxostat protects relatively better against IR injury than allopurinol by suppressing inflammation and apoptosis mediating the MAPK/NF-κBp65/TNF-α pathway.

Clinical significance of cathepsin L and cathepsin B in dilated cardiomyopathy.

Dysregulated expression of lysosomal cysteine cathepsins is associated with adverse cardiac remodeling, a characteristic of several cardiovascular diseases. However, the information regarding the role of cysteine cathepsin L (CTSL) and cathepsin B (CTSB) in dilated cardiomyopathy (DCM) is limited. The present study was aimed to investigate the expression of CTSL and CTSB in animal model of doxorubicin (doxo)-induced cardiomyopathy as well as in peripheral blood samples of DCM patients. Cardiac tissue sections from doxo-treated and control rats were used to study the expression of CTSL and CTSB by enzyme assay and immunohistochemistry (IHC). Peripheral blood mononuclear cells (PBMCs) isolated from DCM patients (n = 29) along with age-matched healthy controls (n = 28) were used to assay enzymatic activity of these cathepsins. Activities of these proteases were further correlated with echocardiographic parameters of DCM patients. A significant increase in CTSL activity and protein expression was observed with no changes in CTSB levels in doxo-treated rats as compared to controls. We also observed a drastic increase in the functional activity of cathepsin L+cathepsin B (CTSL+B), CTSL, and CTSB in DCM patients compared to controls (p ≤ 0.001). Increased levels of these proteases exhibited a statistically significant correlation with reduced left ventricular ejection fraction (LVEF) in DCM patients (ρ = -0.58, p = 0.01). For the first time, this study demonstrates a correlation between increased expression of CTSL and CTSB in PBMCs with severity of left ventricular dysfunction in DCM patients. Thus, these proteases may serve as blood-based biomarker of DCM and prove useful in its management.

Inhibition of PARP activation by enalapril is crucial for its renoprotective effect in cisplatin-induced nephrotoxicity in rats.

Oxidative stress-induced PARP activation has been recognized to be a main factor in the pathogenesis of cisplatin-induced nephrotoxicity. Accumulating literature has revealed that ACE inhibitors may exert beneficial effect in several disease models via preventing PARP activation. Based on this hypothesis, we have evaluated the renoprotective effect of enalapril, an ACE inhibitor, and its underlying mechanism(s) in cisplatin-induced renal injury in rats. Male Albino Wistar rats were orally administered normal saline or enalapril (10, 20 and 40 mg/kg) for 10 days. Nephrotoxicity was induced by a single dose of cisplatin (8 mg/kg; i.p.) on the 7th day. The animals were thereafter sacrificed on the 11th day and both the kidneys were excised and processed for biochemical, histopathological, molecular, and immunohistochemical studies. Enalapril (40 mg/kg) significantly prevented cisplatin-induced renal dysfunction. In comparison to cisplatin-treated group, the elevation of BUN and creatinine levels was significantly less in this group. This improvement in kidney injury markers was well substantiated with reduced PARP expression along with phosphorylation of MAPKs including JNK/ERK/p38. Enalapril, in a dose-dependent fashion, attenuated cisplatin-induced oxidative stress as evidenced by augmented GSH, SOD and catalase activities, reduced TBARS and oxidative DNA damage (8-OHDG), and Nox-4 protein expression. Moreover, enalapril dose dependently inhibited cisplatin-induced inflammation (NF-κB/IKK-ß/IL-6/Cox-2/TNF-α expressions), apoptosis (increased Bcl-2 and reduced p53, cytochrome c, Bax and caspase-3 expressions, and TUNEL/DAPI positivity) and preserved the structural integrity of the kidney. Thus, enalapril attenuated cisplatin-induced renal injury via inhibiting PARP activation and subsequent MAPKs/TNF-α/NF-κB mediated inflammatory and apoptotic response.

A Primate lncRNA Mediates Notch Signaling during Neuronal Development by Sequestering miRNA.

Long non-coding RNAs (lncRNAs) are a diverse and poorly conserved category of transcripts that have expanded greatly in primates, particularly in the brain. We identified an lncRNA, which has acquired 16 microRNA response elements for miR-143-3p in the Catarrhini branch of primates. This lncRNA, termed LncND (neurodevelopment), is expressed in neural progenitor cells and then declines in neurons. Binding and release of miR-143-3p by LncND control the expression of Notch receptors. LncND expression is enriched in radial glia cells (RGCs) in the ventricular and subventricular zones of developing human brain. Downregulation in neuroblastoma cells reduced cell proliferation and induced neuronal differentiation, an effect phenocopied by miR-143-3p overexpression. Gain of function of LncND in developing mouse cortex led to an expansion of PAX6+ RGCs. These findings support a role for LncND in miRNA-mediated regulation of Notch signaling within the neural progenitor pool in primates that may have contributed to the expansion of cerebral cortex.

Pharmacological Properties and Therapeutic Potential of Naringenin: A Citrus Flavonoid of Pharmaceutical Promise.

Naringenin chemically known as 5,7-dihydroxy-2-(4-hydroxyphenyl)chroman-4-one is a common dietary polyphenolic constituent of the citrus fruits. It has received considerable attention for pharmaceutical and nutritional development due to potent pharmacological activities and therapeutic potential. Accruing evidence from both in vitro and in vivo studies have unraveled numerous biological targets along with complex underlying mechanisms suggesting possible therapeutic applications of naringenin in various neurological, cardiovascular, gastrointestinal, rheumatological, metabolic and malignant disorders. Functionally, this ameliorative effect of naringenin is primarily attributed to its antiinflammatory (via inhibiting recruitment of cytokines and inflammatory transcription factors) and anti-oxidant (via scavenging of free radicals, bolstering of endogenous antioxidant defense system and metal ion chelation) effects. The present article provides a comprehensive review of the various studies that have evaluated the therapeutic potential of naringenin and its actions at the molecular level. It also summarizes the pharmacokinetic data and issues and challenges involved in pharmaceutical development and suggest that it may be a potential agent for further exploration as well as may be useful as a dietary adjunct in treatment of various human ailments.
