A case report of severe cardioinhibitory reflex syncope associated with coronavirus disease 2019.

Background: Coronavirus disease 2019 (COVID-19) has been recognized as a disease with a broad spectrum of clinical manifestations. In this report, we illustrate an extraordinary case of severe cardioinhibitory reflex syncope with prolonged asystole associated with COVID-19.

Case Summary: A 35-year-old male patient presented to the emergency department with a 10-day history of postural syncope and fever.

[Nursing care for elderly Holocaust survivors. Experiences of Israeli nurses as related to their own life stories].

As the survivors of the Holocaust grow older and become more dependent on various ways of care and support, the topic of nursing care for elderly Holocaust survivors is becoming increasingly urgent in the last years, and new questions and problems are emerging. This article deals with the experiences of 18 nurses in Israel who work with elderly Holocaust survivors in the community, in homes for the aged, and in hospitals. Some of the nurses mention that they see their patients as especially demanding; some survivors are said to show the conviction that they deserve a better and preferential treatment, as a result of their experiences in the Nazi-persecution.

Free amino acids in the haemolymph of honey bee queens (Apis mellifera L.).

In queen honey bees the free amino acid content in the haemolymph clearly depends on the physiological function and social environment of the individual. While in drones and workers the content of free amino acids increases after emergence until it reaches a peak in 5-day-old animals and decreases afterwards, the amino acid content in queens reaches its highest level (>60 nmol/ microl haemolymph) with the onset of egg laying (10 d of age). This level is about 2.

Importance of proline and other amino acids during honeybee flight--Apis mellifera carnica POLLMANN).

The levels of proline and other amino acids in the haemolymph and other body parts of honeybee foragers were investigated by HPLC analysis. The concentrations of proline in the blood of glucose-fed or -injected bees finishing their exhaustive tethered flights on a roundabout were significantly reduced compared to bees that were fed and rested for one hour. This indicates some utilization of proline during flight metabolism.

Amino acids and osmolarity in honeybee drone haemolymph.

In the haemolymph of honeybee drones, concentrations of free amino acids were higher than in worker haemolymph, with different relative proportions of individual amino acids. The overall concentration of free amino acids reached its highest level at the 5th day after adult drone emergence, and after the 9th day only minor changes in the concentration and distribution of free amino acids were observed. This coincides with the age when drones reach sexual maturity and change their feeding behaviour.
