Acute Appendicitis in a Double Appendix: A Case Report.

Acute appendicitis is one of the most common non-traumatic emergency surgical pathologies, and appendix duplication is a congenital defect that is challenging to diagnose. It is often discovered incidentally during laparoscopy or laparotomy. If a double appendix or other associated anomalies are not detected, complications can be severe and potentially fatal.

A Role for Maternal Factors in Suppressing Cytoplasmic Incompatibility.

are maternally transmitted bacterial endosymbionts, carried by approximately half of all insect species. prevalence in nature stems from manipulation of host reproduction to favor the success of infected females. The best known reproductive modification induced by is referred to as sperm-egg Cytoplasmic Incompatibility (CI).

Mediating Role of Perceived Stress in the Relationship between Facing Existential Issues and Symptoms of Depression and Anxiety.

This study aimed at investigating the mediating role of perceived stress in anticipation of anxiety and depression on facing the ultimate concerns (death, loneliness, freedom, and meaningfulness). A total of 389 students from Ferdowsi University of Mashhad participated in this study in 2017-18. The participants were selected using random sampling.

Quantitative methods for assessing local and bodywide contributions to Wolbachia titer in maternal germline cells of Drosophila.

Background: Little is known about how bacterial endosymbionts colonize host tissues. Because many insect endosymbionts are maternally transmitted, egg colonization is critical for endosymbiont success. Wolbachia bacteria, carried by approximately half of all insect species, provide an excellent model for characterizing endosymbiont infection dynamics.

Predictive Genomic Analyses Inform the Basis for Vitamin Metabolism and Provisioning in Bacteria-Arthropod Endosymbioses.

The requirement of vitamins for core metabolic processes creates a unique set of pressures for arthropods subsisting on nutrient-limited diets. While endosymbiotic bacteria carried by arthropods have been widely implicated in vitamin provisioning, the underlying molecular mechanisms are not well understood. To address this issue, standardized predictive assessment of vitamin metabolism was performed in 50 endosymbionts of insects and arachnids.
