Abstract
The course of Trichinella (T.) spiralis infection includes intestinal and muscle phases. The aims of this work were to evaluate IL-23 and cyclooxygenase-2 (COX-2) by immunohistochemistry in the muscles of T. spiralis infected mice in a time-course study and to correlate their level with the serum levels of IL-23, IFN-γ, IL-4 and IL-10 cytokines. The mice were divided into an un-infected control group (UC) (10 mice) and 5 infected mouse groups (each 10 mice/group. Each mouse was infected with 200 T. spiralis larvae) and sacrificed on days 7, 14, 21, 28 and 35 post-infection (dpi). IL-23 showed weak expression (+1) on the 21st dpi, then it became moderately expressed (+2) on the 28th dpi and on day 35 pi, the immunoreactivity was strong (+3). COX-2 expressed weakly on 14 dpi, while the other mouse groups (21, 28 and 35) showed strong (+3) expression. IL-23 serum concentrations increased gradually in a significant pattern, in comparison to that of UC mice, from the 21st dpi to the end of the experiment. IFN-γ increased gradually and was significantly higher than those of UC mice from the 7th dpi, reached its maximum level on the 21st dpi, after which it decreased non-significantly. IL-4 up-regulated significantly in all infected groups in comparison to UC mice achieving its highest level on the 21st dpi and decreased after that. IL-10 increased significantly on the 7th dpi, but dropped at the 14th dpi, then reached its peak on the 21st dpi, and decreased again on the 28th and 35th dpi. In conclusion, T. spiralis infection caused increased expression of IL-23 and COX-2 in the muscle of infected mice, the effect being strongest on the 35th day. Also, the infection induced a mixed Th1/Th2 profile with a predominance of Th2 at the early muscle phase, after which the immune repose became mainly Th2.

Abstract
The present study was carried out during two successive seasons (2013-2014) at the Research and Agriculture Experiment Station, Dirab, College of Food and Agricultural Sciences, King Saud University, Riyadh. Pollen grains, used in this trial, were collected from eleven male, namely Succary, Menify, Sallag, Dikhiny, Nabout Zamel, Serry, Khalas, Shagra, Safry, Maktumi and Kadary in order to pollinate female Kadary date palm cultivar. Results indicated that pollens of Safry male followed by Succary, Menify and Serry males increased the physical and biochemical characteristics of fruits during both seasons. Also, all the studied characters were significantly affected with different pollen males used in this trial. Pollens of Safry male gave highest fruit retention and bunch weight and best fruit quality like fruit and flesh weight, fruit size and fruit length and fruit biochemical properties as compared with other male. In vitro pollen germination of eleven males was studied using various concentration of sucrose (4, 6, 8 and 10%). The results showed that best germination was achieved with 8% sucrose concentration; however, 10% sucrose resulted in reduced percentage of pollen germination. In addition, pollen tube growth of five males (Succary, Sallag, Nabout-Zamel, Khalas and Safry) at 8% sucrose was alsostudied at 2, 4, 6 and 24 hr time interval. Elongation rate of pollen tube increased significantly after 24 hrs and it was found that pollens of Safry male gave highest pollen tube growth after 24 hrs than pollens of other male.

Abstract
The yellow hornpoppy, Glaucium flavum Cr. (Fam. Papaveraceae) is a perennial herb, distributed in the Mediterranean region, including Egypt. The plant contains many benzyl isoquinoline alkaloids from the aporphine type such as glaucine, isoboldine, 1-chelidonine, 1-norchelidonine and 3-O-methylarterenol, making it to display various medicinal activities including antitussive, anticancer, antioxidant, antimicrobial, antiviral, hypoglycemic, analgesic, antipyretic, bronchodilator and anti-inflammatory effects. The plant is now rare and endangered in the Egyptian flora due to urban sprawl. The present study looks into Glaucium flavum seeds' in vitro germination as well as the ability of the explants taken from the growing seedlings to form stable callus lines in order to enable micropropagation as a way to save the rare plant. The study also scans the production of different medicinally valuable alkaloids, particularly glaucine, in produced callus.

Abstract
The adipocyte-derived hormone adiponectin promotes metabolic and cardiovascular health. Circulating adiponectin increases in lean states such as caloric restriction (CR), but the reasons for this paradox remain unclear. Unlike white adipose tissue (WAT), bone marrow adipose tissue (MAT) increases during CR, and both MAT and serum adiponectin increase in many other clinical conditions. Thus, we investigated whether MAT contributes to circulating adiponectin. We find that adiponectin secretion is greater from MAT than WAT. Notably, specific inhibition of MAT formation in mice results in decreased circulating adiponectin during CR despite unaltered adiponectin expression in WAT. Inhibiting MAT formation also alters skeletal muscle adaptation to CR, suggesting that MAT exerts systemic effects. Finally, we reveal that both MAT and serum adiponectin increase during cancer therapy in humans. These observations identify MAT as an endocrine organ that contributes significantly to increased serum adiponectin during CR and perhaps in other adverse states.
