Purpose: To establish a relationship between falls and handgrip strength (GS) in communitydwelling senior citizens in Egypt. Subjects: Crosssectional study enrolling 132 subjects, all ≥60 years old. Materials and Methods: History of falls in the past year and their number as well as GS measurement in both hands using Baseline? pneumatic squeeze handheld dynamometer. Results: There is a highly significant difference between the GS of fallers and non-fallers in both hands (P = 0.000). There is a highly significant negative correlation between the mean GS and the number of falls (P = 0.003). There is a highly significant positive correlation between GS of the right hand with the number of falls (R = 0.226, P = 0.009), as for the correlation with the left GS it was a weaker positive correlation (R = 0.209, P = 0.16). Conclusion: Seniors with history of falls have a lower GS in both dominant and nondominant hands and it is directly related to the number of falls. GS is decreased in senior fallers even if within the normal range.

The present work was designed to examine the effect of the presence or absence of cumulus cells on the efficiency of vitrification of immature cattle oocytes. In our experiment, we had two groups: group 1, immature cattle oocytes with cumulus cells and group 2, immature cattle oocytes without cumulus cells. The two groups underwent vitrification using 20% ethylene glycol and 20% DMSO, and then thawed, and in vitro matured in TCM-199 medium and examined after 22 hours for assessment of nuclear maturation. Higher survival rate (p < 0.05) after thawing was observed in group 1 (84.6%) than group 2 (57.8%). After in-vitro maturation, the rate of MII oocytes was significantly higher (p < 0.05) in group 1 (74.4%) than group 2 (47.7%). In conclusion, the cumulus cells are very important in increasing the survivability and developmental rate of vitrified-thawed immature cattle oocytes.

AIM： To determine the role of c-Jun N-terminal kinase （JNK） activity in ethanol-induced apoptosis and the modulation of this signaling cascade by S-Adenosylmethionine （AdoMet）. METHODS： Primary hepatocyte cultures were pretreated with 100 IJmol/L SP600125, a selective JNK inhibitor, 1 mL/L DMSO or 4 mmol/L AdoMet and then exposed to 100 mmo/L ethanol. Hepatocyte apoptosis was determined by the TUNEL and DNA ladder assays. JNK activity and its inhibition by SP600125 and AdoMet were determined by Western blot analysis of c-jun phosphorylation and Bid fragmentation. SP600125 and AdoMet effects on the apoptotic signaling pathway were determined by Western blot analysis of cytochrome c release and pro-caspase 3 fragmentation. The AdoMet effect on glutathione levels was measured by EIIman＇s method and reactive oxygen species （ROS） generation by cell cytometry. RESULTS： The exposure of hepatocytes to ethanol induced JNK activation, c-jun phosphorylation, Bid fragmentation, cytochrome c release and pro-caspase 3 cleavage; these effects were diminished by SP600125, and caused a significant decrease in ethanol-induced apoptosis （P〈 0.05）. AdoMet exerted an antioxidant effect maintaining glutathione levels and decreasing ROS generation, without a significant effect on JNK activity, and prevented cytochrome c release and pro-caspase 3 cleavage.CONCLUSION： The JNK signaling cascade is a key component of the proapoptotic signaling pathway induced by ethanol. JNK activation may be independent from ROS generation, since AdoMet which exerted antioxidant properties did not have a significant effect on JNK activity. JNK pathway modulator agents and AdoMet may be components of promising therapies for alcoholic liver disease （ALD） treatment.

Honey locust （Gleditsia triacanthos L.）, also called sweet-locust or thorny-locust, is a moderately fast growing tree. It is widely planted for windbreaks and soil erosion control and largely recommended like food of cattle since it can provide a source of fodder, protein and metabolic energy. Its flowers are incredibly attractive for pollinating insects and thus, form a source of pollen and nectar for honey. This tree was introduced in Europe in 1700 and was introduced by the colonists into Algeria in 1949. In order to valorize the natural substances of this species, the evaluation of the composition of its fruits （pods and seeds separately） in polyphenols, condensed tannins and hydrolysable tannins, which considered as anti-nutritional substances has been done. The obtained results showed that the fruits of Gleditsia triacanthos L. contain very low values in anti-nutritional factors with （0.13%-0.03%） of condensed tannins, （0.78%-0.45%） of hydrolysable tannins and （0.44%-0.16%） of total phenols for pods and seeds, respectively. It arises that these fruits can be of a great interest for many industries especially for feedstock.
