Rhizoleucinoside (1), a unique rhamnolipid-amino alcohol hybrid, was isolated from the rhizobial symbiont bacterium Bradyrhizobium sp. BTAi1. Compound 1 features a rare rhamnolipid core attached to an unprecedented leucinol moiety. Its structure and absolute configuration were determined by spectroscopic analysis, tandem mass spectrometry, chemical degradation, and application of the Marfey's m...

Introduction: The most effective agent for prophylaxis against venous thromboembolic disease (VTE) following total joint arthroplasty (TJA) remains unknown. The paucity of literature comparing the different methods of pulmonary embolus (PE) prophylaxis and fear of litigation make it difficult for surgeons to abandon the use of aggressive chemical prophylaxis. The purpose of our study is to comp...

SYNOPSIS. Animals commonly modify their behavior in the presence of a conspecific or in response to signals. This is particularly true in the context of aggressive exchanges, which animals use to form networks of social relationships and to communicate social status associated with those relationships. Although hierarchical structures are a widespread phenomenon that has been studied extensivel...

Does oxytocin influence intimate partner violence? Clues from prior research suggest that oxytocin increases prosocial behavior, but this effect is reversed among people with aggressive tendencies or in situations involving defensive aggression. Animal research also indicates that oxytocin plays a central role in defensive maternal aggression (i.e., protecting pups from intruders). Among highly...

The article describes the definition of filtration flow gradients in dam's body on example Kattakurgan reservoir, analysis reasons for their change cross-section. Evaluation aggressiveness plays an important role ensuring stability reservoir dam and its parts. To assess body, it is necessary to know action pattern water effect elements dam. In addition, chemical composition piezometers was anal...

background: aggressive personality changes are one of the most prevalent neuropsychiatric disorders after traumatic brain injury (tbi). it may lead to serious impairments in social relations and affect rehabilitation process. present research was performed to identify the determinant factors of personality change of aggressive characteristics after tbi. methods: 238 tbi patients (195 men and 43...

Despite the innumerable ecological problems and large economic costs associated with biological invasions, the proximate causes of invasion success are often poorly understood. Here, evidence is provided that reduced intraspecific aggression and the concomitant abandonment of territorial behavior unique to introduced populations of the Argentine ant contribute to the elevated population densiti...

This cross-sectional study was conducted on the drinking water resources of the city of Jolfa (East Azerbaijan province, Iran) from samples taken from 30 wells. Calcium hardness, pH, total alkalinity, TDS, temperature and other chemical parameters were measured using standard methods. The Langelier, Rayzner, Puckhorius and aggressive indices were calculated. The results showed that the Langelie...
