Dynamics of heat shock proteins and heat shock factor expression during heat stress in daughter workers in pre-heat-treated (rapid heat hardening) Apis mellifera mother queens.

Honeybees have a limited capacity to control their body temperature when exposed to thermal changes in the atmosphere. Environmental changes, such as thermal climate change, have an adverse effect on honeybee survival. Insects can be pre-heat-treated (rapid heat hardening) with a mild heat stressor to induce Hsp gene expression and protect them from future stresses.

Effect of Maternal Water Restriction on Sexual Behavior, Reproductive Performance, and Reproductive Hormones of Male Rat Offspring.

The present study aimed to investigate the effect of maternal water restriction on sexual behavior, reproductive performance, and reproductive hormones of male rat offspring. Forty pregnant female rats were divided into two equal groups: Control (C) and water-restricted (WR). Control dams had ad libitum water access throughout pregnancy, while dams in the WR group were subjected to 50% water-restriction from day 10 of pregnancy onwards.

Preliminary study of the influence of mineral content on quality parameters of Jordanian-origin honey collected from different geographical regions.

In this work, physicochemical properties of eight honey samples harvested from different regions over Jordan were investigated. Quality parameters including free acidity, pH, conductivity, 5-hydroxymethylfurfural (5-HMT) and diastase activity were monitored for freshly harvested samples and during storage time over 24-month. The level of minerals (Na, K, Mg, Ca, Fe, Ni, Cu, Hg, Pb and As) in samples were quantified and found to be highly variable.
