Papaver libanoticum is an endemic plant to Lebanese region (family Papaveraceae) that has not been investigated before. The present study aimed to explore the analgesic activity of dried ethanolic extract of Papaver libanoticum (PLE) using tail flick, hot plate, and acetic acid induced writhing models in mice. The involvement of opioid receptors in the analgesic mechanism was investigated using...

Darwin was initially puzzled by the processes that led to ornamentation in males-what he termed sexual selection-and those that led to extreme cooperation and altruism in complex animal societies-what was later termed kin selection. Here, I explore the relationships between sexual and kin selection theory by examining how social competition for reproductive opportunities-particularly in females...

Every year, a large amount of population reconciles gun-related violence all over the world. In this work, we develop computer-based fully automated system to identify basic armaments, particularly handguns and rifles. Recent work in field deep learning transfer has demonstrated significant progress areas object detection recognition. We have implemented YOLO V3 “You Only Look Once” model by tr...

На основе анализа ранее не опубликованных архивных материалов исследуется деятельность наркомата вооружения накануне Великой Отечественной войны. Выявлены факторы, повлиявшие на достижения в работе оборонных заводов, а также причины допущенных просчетов. Рассмотрены предпосылки регулярных реорганизаций системе управления оборонной промышленностью 1930-е годы, ряду которых — значительное увеличе...

Sexual selection is responsible for the evolution of male ornaments and armaments, but its role in the evolution of cognition--the ability to process, retain and use information--is largely unexplored. Because successful courtship is likely to involve processing information in complex, competitive sexual environments, we hypothesized that sexual selection contributes to the evolution and mainte...

It is well recognized that early detection and cancer prevention are significant armaments in the 'war against cancer'. Changes in lifestyle and diet have significant impact on the global incidence of cancer. For over 30 years, many investigators have studied the concept of chemoprevention. More recently, with the demonstration that antiangiogenic activity reduces tumor growth, the concept of a...

The rollout of the first production C-130 aircraft, the C-130A, took place on March 10, 1955. Since then, more than 2,100 C-130s have been built in dozens of variations and are flown by more than 60 nations worldwide. They carry troops, vehicles, and armaments into battle. They drop paratroopers and supplies from the sky. They serve as airborne and ground refuelers. They serve as flying hospita...

Males figured more prominently than females in Darwin's view of sexual selection. He considered female choice of secondary importance to male-male competition as a mechanism to explain the evolution of male ornaments and armaments. Fisher later demonstrated the importance of female choice in driving male trait evolution, but his ideas were largely ignored for decades. As sexual selection came t...

In contests among males, body condition is often the key determinant of a successful outcome, with fighting ability signaled by so-called armaments, that is, exaggerated, condition-dependent traits. However, it is not known whether condition and exaggerated traits function in the same way in females. Here, we manipulated adult condition by varying larval nutrition in the stalk-eyed fly, Teleops...

Pathogenic bacteria such as Yersinia pestis, causative agent of the plague, have a genetic armoury proteins they use to defend themselves against immune system when invading host. Upon invasion, Y. pestis deploy molecular cloaking device, made protein called Caf1, which allows them avoid being eaten by host’s macrophage cells. Caf1 has several interesting structural properties that allow it car...
