Effect of gender, leg dominancy and body mass index on Y-balance performance among young healthy adults

This study investigated the influence of the sex, dominant leg and BMI on dynamic balance control of young adults (mean age; 20 ± 1.56) using the Y-balance test-lower quarter (YBT-LQ). This cross-sectional study included 218 participants (105 men and 103 women) who were recruited as a convenient sample of young, normal adults. The examination was implemented in one session, with three trials in each direction on each leg. The maximum reach distance of the three trials in each direction was used for statistical analysis. The reported reach distances were also normalized for each participant's leg length. Males' right leg values in the posteromedial (PM), posterolateral (PL), and composite directions were substantially longer than females' (p<0.05), and no significant difference between both sexes in anterior (AT) direction (p>0.05). In all directions, there were no significant differences between both sexes for the left leg (p>0.05), and no significant differences between the right values of the dominant and non-dominant legs (p>0.05). However, the left values of the non-dominant legs were longer than the dominant leg in directions (p<0.05). The right leg values of the AT, PM, and composite values of the average BMI subjects was greater than the over-weight and obese subjects (p<0.05), and the left leg values of the AT and composite values of the average BMI subjects was greater than over-weight and obese subjects (p<0.05). Males have a longer right leg reach distance in the PM, PL directions, and composite value compared to females. The right leg dominant participants have longer reach distance of the left leg in all directions. When compared to over-weight and obese participants, average body weight subjects have bilaterally larger reach distance in the AT and composite directions

Mineralogical Study and Restoration of the Lid of an Alabaster Sarcophagus in the Step Pyramid, Saqqara, Egypt

The pyramid of king Djoser in Saqqara is one of the oldest stone building in history. There are five levels of corridors under the pyramid. There are two alabaster sarcophaguses in the fifth level. It is thought that they are for two daughters of king Djoser, although they were found empty. The lid of one of these sarcophaguses were found broken into nine pieces. Mineralogical investigations by both X-Ray diffraction and polarizing microscope were required to help identifying the components of the alabaster lid. The obtained results revealed that mineralogical study should have been carried out to achieve the restoration processes. The restoration process was carried out. The broken pieces of the lid were collected and glued, the lid was put in its place and the sarcophagus was closed. A drill, stainless steel bars and an epoxy called Araldite AW 106 were used in the restoration process. The restoration process was completed successfully

Hypocholesterolemic Operating Parameters of Novel Probiotics In vitro

The Hypocholesterolemic is an effective and friendly process for the removal of cholesterol and an important aspect of human health. Removal of cholesterol by probiotic bacteria was investigated in this study. The potential probiotic bacterium was preliminarily identified as Lactobacillus casei. In addition, the various operating parameters like cholesterol concentration, incubation time, bile salts concentration, probiotic dose and initial pH was studied. The optimum parameters for most probiotics studied are cholesterol concentration is 100 μg /ml, incubation time is 48 h, bile salts concentration is 0.5%, probiotic dose is 200μl and initial pH is 6. The maximum percentage removal of cholesterol using Lactobacillus casei is 93.6. The probiotics bacteria are favorable for Hypocholesterolemic.</jats:p

Biotechnological applications of fungal endophytes associated with medicinal plant Asclepias sinaica (Bioss.)

AbstractFungal endophytes associated with medicinal plants have potential role to promote plant growth through different mechanisms. However, the biological and ecological roles of fungal endophytes still totally unexplored. In this study, three different fungal endophytes were isolated from the medicinal plant of Asclepias sinaica and identified as Penicillium chrysogenum Pc_25, Alternaria alternata Aa_27 and the third fungal strain was described as sterile hyphae Sh_26. It was recorded that, these endophytes had various ability to produce several extracellular enzymes including amylase, pectinase, cellulase, gelatinase, xylanase and tyrosinase. Their antimicrobial activities against different specific test organisms were investigated as well. In addition, both endophyte isolates i.e. Sh_26 and Aa_27 were found to promote root growth higher than Pc_25 and control treatments. These fungal isolates had a considerable impact on plant growth parameters including root elongation as a result of ammonia and IAA production
