Introduction: Cholinesterase inhibitor insecticides, mainly organophosphates and carbamates, are very common to be used in Egypt. Chronic male and female exposure in agricultural workers is expected. Unfortunately, most of workers in agriculture don’t follow the procedures of protection from insecticides exposure on handling. Unnoticed exposure to insecticides could occur due to environmental pollution. Objective: The work aimed to relate exposure to cholinesterase pesticides to the development of pelvic inflammatory disease (PID). Subjects and methods: The study was conducted on seventy women aged between 19 and 47 year, who were visiting the Outpatient Gynecology and Obstetrics Clinic of Tanta university hospital during 2015 and the first 3 months of 2016. They were clinically suspected to complain from PID based on patients’ history and clinical findings. Blood samples were collected from each patient for measurement of red blood cells cholinesterase activity and cervical swaps were obtained for microbiological examination. Results: According to patients’ history 16 patients were exposed to cholinesterase inhibitors insecticides while 54 patients were non-exposed. Cholinesterase activities were significantly depressed in exposed females (6.36±0.8)µ moles/min/ ml red cells when compared with non-exposed (7.5±1.2) µ moles/min/ ml red cells (P=0.0009). Laboratory confirmed cervical infection was detected in 37 (52.6%) of cases with significant gram-negative organisms isolation (59.5%, P<0.00001) and significant decrease in the mean enzyme activity value in culture positive cases (6.4±0.8, P<0.0001). Patients with enzyme activity ≤7µ moles/min/ ml red cells were more susceptible to infection. Conclusion: Exposure to cholinesterase inhibitors pesticides could increase the occurrence of pelvic inflammatory disease.

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the third most common cause of cancer deaths. HCC, accounting for 90% of primary liver cancer and is a global clinical issue. For improvement in the prognosis of HCC, curative therapy following early detection is important. To this end, it is critical to identify high risk groups for HCC and perform appropriate surveillance in the clinical practice of chronic liver disease
In Egypt, HCC is reported in about 4.7% of chronic liver disease * (CLD). El-Zayadi et al in 2005 reported an almost twofold increase in HCC among Egyptian patients with CLD between 1993 and 2003. Since then, HCC was reported as the second cause of cancer incidence- and mortality in men. Therefore, HCC represents an important public health problem in Egypt with increasing incidence uptill now.
This currently increased HCC incidence may be the result of a shift in the relative importance of HBV and HCV as primary risk factors. Egypt has the highest prevalence of HCV in the world. Further risk factors were then emerged with great importance. The major risk factors for HCC will be discussed.

The pursuit of high sports levels, promotion of sports achievement and break of sport activities records depend basically on the good planning for training and a sport which requires special abilities of its players. These abilities are defensive and offensive actions performed realistically, that is, Kumite, or delusively, which is called Kata. The swimming is regarded as the most beneficial sport to the body because it strengthens all organs of body as it develops the muscles and makes them flexible because all muscles work together and therefore it increases the strength of muscles. It develops will, bravery, patience and stability and it enhances the self-reliance.
This study aims at identifying the impact of training program inside the aqueous medium using the snorkel (breathing tube) upon the performance level of some Kumite skills in Karate and the use of experimental method. The sample was divided into a control group (10 players) and an experimental group (10 players) from Sporting Castle club in Gharbia Governorate (under 18). The physical and skill tests were made for karate players and the period of training program was six weeks. From the statistical processing, the researchers found that there are statistical differences between the control and experimental groups in favor of experimental group and that there are differences between the Before and After measurements in favor of the After measurements. This indicates how the training program is effective to the enhancement of skill performance level for the Kumite players.

There are negative impacts on the environment and human health derived from the application of chemical fungicides in traditional agricultural production systems for control of crop diseases. These consequences created an increasing demand for developing environmentally safe agrochemicals to promote sustainable and healthy food production. The use of plant secondary metabolites with antifungal properties is one of these approaches. In the current study, the total harmala alkaloids (THAs), the β-carboline alkaloids harmane, harmine, harmaline, harmalol and the two quinazolines, peganine (vasicine) and vasicinone were isolated from Peganum harmala. Their structures were elucidated using spectroscopic methods (UV, IR, 1H-NMR, 13C-NMR, and 2D 1H-1H COSY). Using mycelial growth inhibitory technique, harmala alkaloids exhibited considerable fungicidal activity against the phytopathogenic fungi Alternaria alternate, Botrytis cinerea, Fusarium oxysporum and Colletotrichum acutatum. THAs was the most potent antifungal fraction against the four test fungi with EC50 values of 16.5, 23.3, 31.8 and 37.5 µg/ml against C. acutatum, F. oxysporum, B. cinerea and A. alternate, respectively. Harmine and harmaline showed moderate activities, while harmalol and the two quinazolines showed weak activities. Silver nanoparticles (AgNPs) prepared using harmala alkaloids showed improved fungitoxic activity, where EC50 values of THAs ranged between 9.3 and 17.4 µg/ml. The antifungal activity of alkaloids was comparable to a reference fungicide, carbendazim Many of the tested alkaloids were non-phytotoxic and showed no or low toxicity against experimental animals. The study recommends the potential of using harmala alkaloids, especially at their nanoscale, as biorational alternatives to conventional fungicides after the required toxicological assessments.

Toxicological effects of some chemicals on organogenesis in human fetal life are reported since 40 years. They were presented as case reports. Recently there is more awareness about the hazardous effects on pregnant women. One of the paramount effects is on genital system as reflected by threefold increase in hypospadias incidence and 2 fold increase in undecided testes recently as compared to incidence 3 decades ago. Animal proofs as described in many experiments confirmed this fact. This is documented by human prevalence of these specific genital anomalies in agricultural areas in farms of California and central Eastern Europe like Hungary in many population based studies. Occupational and environmental exposures to Endocrine Disruptor Compounds in non genetic isolated hypospadias proved in many studies. Organocholrine pesticides have been documents the deleterious effect on pregnant farm female workers. Do we have an awareness program to our female farmers or partners as we have almost the same increase in genital anomalies are still warranted. The same pesticides are used in Egypt. Multi team approaches are needed to help our community and generations as current fetuses are future leaders of the nation.

Producing lightweight concrete with suitable structural properties is always a challenge specially in case of using local available constituent materials. On the other hand, adding fibers to the concrete mix enhances various characteristics of the concrete such as cracking behavior and toughness. Conventional concrete loses its strength after formation of multiple cracks. However, fibrous concrete can sustain a portion of its resistance following cracking to resist more cycles of loading.
In this research, exploratory study was performed to evaluate the main properties of fibrous lightweight concrete made of different local available wastes aggregates (i.e. crushed clay and lightweight bricks). Based on the experimental results, the maximum reduction in concrete bulk density was 1.15 gm/cm3 for crushed white bricks and 1.34 gm/cm3 for crushed red bricks compared to 2.2 gm/cm3 for normal weight aggregate concrete. On the other hand, minimum reduction of compressive strength was 5.15 Mpa for crushed white bricks and 9.54 Mpa for crushed red bricks compared to 22.84 Mpa for normal weight aggregate concrete.
