A number of studies have implicated the direct involvement of the liver in dengue virus (DENV) infection, and it has been widely shown that liver cells subsequently undergo apoptosis. The mechanism by which liver cells undergo apoptosis in response to DENV infection remains unclear. To provide further information on the mechanism of apoptosis in DENV infected liver cells, HepG2 cells were infected with DENV 2 and analyzed for the induction of ER stress, apoptosis and autophagy. In response to DENV infection, HepG2 cells showed the induction of both the ER resident unfolded protein response as well as the Noxa/PUMA stress response pathways. Proteolytic activation of caspases 4, 7, 8 and 9 was observed as well as changes in mitochondrial transmembrane potential. Increased monodansylcadaverine staining was observed in DENV infected cells, consistent with the previously reported induction of autophagy. These results are consistent with a model in which the induction of multiple ER stress pathways is coupled with the induction of multiple cell death pathways as a mechanism to ensure the removal of infected liver cells from the system.

Cardiopulmonary arrest in pregnancy has a very high maternal and fetal mortality rate. We report a case of successful maternal and neonatal survival in association with emergency cesarean section of a schizophrenic pregnant patient. To our knowledge, this is the first reported case of cardiopulmonary arrest in a pregnant woman with schizophrenia. The parents were Japanese. The mother was 39 years old and had no history of prior pregnancy. Her admission to our hospital at 36 weeks and 4 days of pregnancy was due to deterioration of schizophrenia. On the first day of hospitalization, she collapsed after a seizure and vomiting, and an emergency resuscitation team was called immediately. The team identified apparent aspiration and successfully resuscitated the patient after 11 minutes of cardiopulmonary arrest. An emergency cesarean section was performed in the operating room. The newborn male infant received bag and mask ventilation at birth, and his Apgar scores were 5 at 1 minute and 8 at 5 minutes. He had a myoclonic seizure on the 2nd day of life: however, he experienced no further seizures on anticonvulsant medication after that episode. On the 18th day of life, magnetic resonance imaging of his brain revealed bilateral small hyperintensities on T1-weighted images in the basal ganglia. The mother and her newborn were discharged from our hospital without neurological disorders. We speculate that the cause of cardiopulmonary arrest was aspiration due to seizure, and it is possible that a neurological response was evoked by administration of antipsychotic drugs and/or by eclampsia. Medical staff must be aware of the possibility of cardiopulmonary arrest in pregnant women with schizophrenia.

The major objective of the study was to sequence the whole genome of four Bangladeshi individuals and identify variants that are known to be associated with functional changes or disease states. We also carried out an ontology analysis to identify the functions and pathways most likely to be affected by these variants. We identified around 900,000 common variants and close to 5 million unique ones in all four of the individuals. This included over 11,500 variants that caused nonsynonymous changes in proteins. Heart function associated pathways were heavily implicated by the ontology analysis; corroborating previous studies that claimed the Bangladeshi population as highly susceptible to heart disorders. Two variants were found that have been previously identified as pathogenic factors in familial hypercholesteremia and structural disorders of the heart. Other pathogenic variants we found were associated with pseudoxanthoma elasticum, cancer progression, polyagglutinable erythrocyte syndrome, preeclampsia, and others.

Abstract Objective Adolescence as one of the most challenging periods of humans’ growth is accompanied with major physical, behavioural, social-emotional, and neuroendocrine changes. Early maturation and eating disorders (EDs) have been reported to be associated with adverse health conditions. Therefore, the present study was conducted to assess age of onset of menarche (AM), EDs, and their possible relationships with weight, body mass index (BMI), waist circumference (WC), and socioeconomic status (SES) in the Iranian female adolescents. Results In the study population, mean ± standard deviation (SD) of AM was 12.95 ± 1.14 years. Inverse significant relationships were found between weight and AM, also BMI and AM (p < 0.05). There was a negative association between weight and anorexia nervosa (AN), BMI and AN, also WC and AN (p < 0.001). A significant positive correlation was found between SES and AM, also EDs and AM (p < 0.05) then between weight and bulimia nervosa (BN) & binge-eating disorder (BED), BMI and BN & BED, also WC and BD & BED (p < 0.001). Our results also revealed that AM in mothers had a significant positive relationship with AM in their daughters (p < 0.001, r = 0.34).

A proper uptake of maternity waiting homes (MWHs) is important to improve maternal and child health (MCH). The aim of this review is to generate the best existing evidences concerning the MWHs utilization and its impact on perinatal mortality (PNM) among pregnant mothers in Africa. Both relevant quantitative and qualitative studies, investigated and reported from databases were explored. Meta-analysis of the studies was displayed by tables and forest plots. The Stata version 14 was used with the fixed effect model and 95% confidence interval. In this review, a total of 68,805 births were recorded in this review. About 1.6% and 7.2% PNM occurred among non-exposed and exposed mothers respectively. Fifty percent of the studies showed there is a significant association between MWHs use and PNM. Meta-analysis revealed that utilizing MWHs have a significant effect in a reducing PNM by 82.5% (80.4%–84.5%), I2 = 96.5%. Therefore, use of MWHs has a potential to reduce PNM among pregnant mothers. The review revealed that MWHs relevance to achieving sustainable development goals (SDGs) concerning reducing newborn mortality. Therefore, the utilization rate of MWHs must be enhanced to achieve SDGs.

GFF-Ex: a genome feature extraction package

Genomic features of whole genome sequences emerging from various sequencing and annotation projects are represented and stored in several formats. Amongst these formats, the GFF (Generic/General Feature Format) has emerged as a widely accepted, portable and successfully used flat file format for genome annotation storage. With an increasing interest in genome annotation projects and secondary and meta-analysis, there is a need for efficient tools to extract sequences of interests from GFF files. We have developed GFF-Ex to automate feature-based extraction of sequences from a GFF file. In addition to automated sequence extraction of the features described within a feature file, GFF-Ex also assigns boundaries for the features (introns, intergenic, regions upstream to genes), which are not explicitly specified in the GFF format, and exports the corresponding primary sequence information into predefined feature specific output files. GFF-Ex package consists of several UNIX Shell and PERL scripts. Compared to other available GFF parsers, GFF-Ex is a simpler tool, which permits sequence retrieval based on additional inferred features. GFF-Ex can also be integrated with any genome annotation or analysis pipeline. GFF-Ex is freely available at http://bioinfo.icgeb.res.in/gff .
