Abstract
Increased anxiety and depressive symptoms have reported to be its association with long term illness. Because of having unwanted effects of newly available drugs, patients administering anxiolytic drugs usually discontinue the treatment before they are completely recovered. Therefore, there is a serious need to develop new anxiolytic drugs. The anxiolytic effect of hydro-alcoholic extract of Agaricus blazei in animal models was assessed. 24 male mice (Mus musculus genus) were included in the study. Four groups were prepared and each group contained six animals. The groups were vehicle control, positive control (diazepam 1.0 mg/kg, i.p.) as well as two treatment groups receiving Agaricus blazei hydro-alcoholic extract at a dose of 136.50 mg/kg and 273.0 mg/kg orally. The Marble burying test, Nestlet shredding test and Light and Dark box test used to assess anxiolytic activity. Mice administered with diazepam 1.0 mg/kg, i.p. while hydro-alcoholic extract of AbM (136.50 and 273.0 mg/kg, respectively) was administered via oral route which exhibited marked reduction in number of marbles-burying as compared to vehicle control group. Mice administered with diazepam 1.0 mg/kg, i.p. and Oral administration of hydro-alcoholic extract of AbM (136.50 and 273.0 mg/kg, respectively) exhibited significant decrease in nestlet shredding in comparison to vehicle control group. The oral administration of hydro-alcoholic extract at a dose of 136.5mg/kg and 273mg/kg showed elevation in time spent in light box and was comparable to standard treated group while time spent by mice following oral administration of hydro-alcoholic extract of Agaricus blazei at a dose of 273.0 mg/kg also showed elevation and was found to be more near to standard treated group (diazepam 1 mg/kg, i.p.).

Kaushal-Deep SM, Ahmad R, Lodhi M, Chana RS. A prospective study of evaluation of operative duration as a predictor of mortality in pediatric emergency surgery: Concept of 100 minutes laparotomy in resource-limited setting. J Postgrad Med 2018; 65:248492.

Abstract
INTRODUCTION Operative duration is an important but under-studied predictor of mortality in emergency laparotomies. AIMS AND OBJECTIVES The primary objective of this study was to quantify the effect of duration of emergency laparotomy in children on mortality; and to identify a rough cut-off duration of laparotomy to serve as a guide so that a laparotomy can be planned to optimize pediatric surgical patient outcome. MATERIALS AND METHODS This is a prospective study conducted in a government tertiary teaching institution over a period of 24 months. All children in the age group of 5-10 years presenting in the emergency department with Pediatric Risk of Mortality III score ≤8, undergoing emergency laparotomy in emergency operation theater, were included. OBSERVATIONS AND RESULTS In all, 213 children were included in the study. The mean time from presentation to shifting to the operating room was 3.7 h. The mean operative duration was 108 min. The mean operative time in survived patients was 102 min as compared to 135 min in expired patients (P < 0.05). The 30-day in-hospital mortality rate was 17.4%. After application of binary logistic regression analysis, it was found that time to laparotomy and operative duration were significant risk factors (<0.05) predicting post-operative mortality. Kaplan-Meier survival curve showed a decrease at a mean weighted operative duration of approximately 100 min. Receiver operating characteristic curve analysis yielded operative duration of 123.5 min at which Youden's index maximized. CONCLUSION This 100-min duration of laparotomy might appear a long duration but in casualty setup of a government hospital with limited resources, there are so many hurdles for optimal working that completion of an emergency laparotomy in children in 100 min can be considered a realistic target for improving post-operative outcome. At an operative duration of <123.50 min, mortality rates within acceptable limits can be achieved.

Abstract
We report a case of incarcerated left indirect inguinal hernia in a male child which on exploration revealed the presence of free air and fecal matter containing fluid in the hernial sac. This is the second reported case of the presence of cecal perforation in left Amyand's hernia in pediatric age group and unique in the sense of the form of abnormal anatomy encountered per-operatively.

Abstract
The higher plant Arabidopsis thaliana (Arabidopsis) is an important model for identifying plant genes and determining their function. To assist biological investigations and to define chromosome structure, a coordinated effort to sequence the Arabidopsis genome was initiated in late 1996. Here we report one of the first milestones of this project, the sequence of chromosome 4. Analysis of 17.38 megabases of unique sequence, representing about 17% of the genome, reveals 3,744 protein coding genes, 81 transfer RNAs and numerous repeat elements. Heterochromatic regions surrounding the putative centromere, which has not yet been completely sequenced, are characterized by an increased frequency of a variety of repeats, new repeats, reduced recombination, lowered gene density and lowered gene expression. Roughly 60% of the predicted protein-coding genes have been functionally characterized on the basis of their homology to known genes. Many genes encode predicted proteins that are homologous to human and Caenorhabditis elegans proteins.

Abstract
The yeast and human SKP1 genes regulate the mitotic cell cycle but are not yet known to be required for meiosis. Nine Arabidopsis SKP1 homologues have been uncovered and are named ASK1 through ASK9. Here, we report the isolation and characterization of a male sterile Arabidopsis mutant and show that the mutant defect was caused by a Ds transposon insertion into the ASK1 gene. In the ask1-1 mutant, abnormal microspores exhibit a range of sizes. Furthermore, during mutant male meiosis, although homologous chromosome pairing appeared normal at metaphase I, chromosome segregation at anaphase I is unequal, and some chromosomes are abnormally extended. Therefore, in ask1-1, at least some homologues remain associated after metaphase I. In addition, immunofluorescence microscopy indicates that the mutant spindle morphology at both metaphase I and early anaphase I is normal; thus, the abnormal chromosome segregation is not likely caused by a spindle defect. Because the yeast Skp1p is required for targeting specific proteins for ubiquitin-mediated proteolysis, we propose that ASK1 controls homologue separation by degrading or otherwise removing a protein that is required directly or indirectly for homologue association before anaphase I.
