PIN13 - Prevelance of Hydeted Disease in Sugicaly Operated Patient in Some Libyan General Hospital

Determine the prevalence of HD in cases referred to surgical wards in four hospitals in east part of Libya during period from 2004 to 2009. Data was collected from four hospitals; Tripoli medical centre, central Hospital, Alzawia hospital and Gharian general hospital. Hospital data of, patients diagnosed as HD were collected from surgical departments. Out of 94,142 files were reviewed from four Hospitals there were 401(0.42%) confirmed cases of Hydatid disease. Among these medical records there were 233(58.1%) from Tripoli Medical Centre, 144(35.9%) from Centre Tripoli Hospital, 16(4%) from Al Zawiyah Hospital and 8(2%) from Gharyan Hospital. The gender distributions were 41.4% males and 58.6% females. Young adult ages between 15-30 were most commonly infected (35%). Liver and lungs was most common site of infection (81.1% and 13.5% of cases, respectively) Spleen was (2.0%). Cysts were found in sites like Pancreas, Ovary and kidney were (3.4 %) Hydatid disease is a Health problem affecting young Libyan population. The mean age of the patients was (2-40) years and more common in women) housewives) and students, the most common site of HD found in liver followed by lungs. Further studies are required to find the etiologic factors of HD in different areas in Libya.

Northwest Libya from the early to late Holocene: New data on environment and subsistence from the Jebel Gharbi

The area of Jebel Gharbi, west of Cyrenaica province and the research area of the Italian–Libyan Joint Project (Sapienza University of Rome and Cassino), showed a continuity of occupation even during the most difficult periods of the Last Glaciation, marked by the abandonment of much of North Africa. One of the main research subjects of the project concerns the transformation of hunting societies during the Holocene, with the gradual transition to a food production economy, and the type of Neolithic organization on the coastal Libyan territory.This paper emphasizes this theme and takes into account especially the areas that have allowed for palaeoclimatic and geo-archaeological reconstruction in a broader perspective, including changes in the settlement pattern and the economic system. These conditions were recognized in the Jefara, the plain which begins at the slopes of the Jebel Gharbi plateau and reaches the coast.I describe the principal characteristics of the sites investigated along a belt that runs from Shakshūk to El Jawsh, where a long period of climate stability in the mid-Holocene and particularly between 6.7 and 5.4 ka cal BP, was recognized through the presence of large ponds and marshes that became an important focus for human occupation. Taking into account the palaeoenvironmental context, the paper suggests a model of economic change in the Jebel Gharbi/Jefara region through three different phases of development (Jefara A, B, C), that can be compared with the most recent results of research in other areas of Libya and the Maghreb.

Tracking the “Arab Spring”: Libya Starts from Scratch

Abstract: Libya is building a new state and political order in the context of unique and difficult legacies compared to other Arab Spring countries. The primary challenge faced by Libya’s leaders is that of statelessness—the fatal weakness of central state institutions—that is a legacy of the Qadhafi regime, and before that the post–World War II kingdom. Challenges of statelessness cut across chronic problem areas in Libya’s transition, including reining in militias outside of state control, justice-sector reform, constitution making, and economic development. Such an institutional void reinforces already low levels of social trust and negatively impacts the legitimacy of the central government and the democratization process more generally. It also empowers Islamism and other illiberal ideologies as the potential bases on which to build a new Libyan identity.

Prevalence, predictors and clinical significance of Blastocystis sp. in Sebha, Libya

BackgroundBlastocystis sp. has a worldwide distribution and is often the most common human intestinal protozoan reported in children and adults in developing countries. The clinical relevance of Blastocystis sp. remains controversial. This study was undertaken to determine the prevalence of Blastocystis infection and its association with gastrointestinal symptoms among outpatients in Sebha city, Libya.MethodsA total of 380 stool samples were collected from outpatients attending the Central Laboratory in Sebha, Libya for routine stool examination. The presence of Blastocystis sp. was screened comparing light microscopy of direct smears against in vitro cultivation. Demographic and socioeconomic information were collected with a standardized questionnaire.ResultsThe overall prevalence of Blastocystis infection was 22.1%. The prevalence was significantly higher among patients aged ≥18 years compared to those aged < 18 years (29.4% vs 9.9%; x2 = 19.746; P < 0.001), and in males compared to females (26.4% vs 17.5%; x2 = 4.374; P = 0.036). Univariate analysis showed significant associations between Blastocystis infection and the occupational status (P = 0.017), family size (P = 0.023) and educational level (P = 0.042) of the participants. Multiple logistic regression analysis confirmed that the age of ≥ 18 years (OR = 5.7; 95% CI = 2.21; 9.86) and occupational status (OR = 2.2; 95% CI = 1.02, 4.70) as significant predictors of Blastocystis infection among this population. In those who had only Blastocystis infection but no other gastrointestinal parasitic infections, the prevalence of gastrointestinal symptoms was higher compared to those without Blastocystis infection (35.3% vs 13.2%; x2 = 25.8; P < 0.001). The most common symptoms among these patients were abdominal pain (76.4%), flatulence (41.1%) and diarrhoea (21.5%).ConclusionsBlastocystis sp. is prevalent and associated with gastrointestinal symptoms among communities in Sebha city, Libya. Age and occupational status were the significant predictors of infection. However, more studies from different areas in Libya are needed in order to delineate the epidemiology and clinical significance of this infection.

CYTOTOXIC ACTIVITY OF SELECTED LIBYAN MEDICINAL PLANTS ON HUMAN BREAST ADENOCARCINOMA CELL LINE (MCF-7)

Three Libyan plants namely Ballota pseudodictamnus, Hedera helix, Thapsia garganica were tested for anticancer activity. The plants, collected from Aljabal-Al-Akhdar area of Libya in April 2010 were shed dried and subjected to Soxhlet extraction by methanol. Phytochemical screening indicated the presence of 2-deoxy sugars, flavonoids, saponins and tannins but absence of alkaloids in all three plants under investigation. Antiproliferative activity was performed breast adenocarcinoma cell line (MCF7). At the concentration of 100µg/mL, B. pseudodictamnus, T. garganica and H. helix showed 90, 60 and 5% cell death, respectively as compared to the control. Key words: Antiproliferative; Breast adenocarcinoma; Cell l ine MCF-7

Recommendations and Thermal Insulation for Desert Countries

This paper focuses on the analysis of the weather conditions during the day and at night in the dessert areas in Libya, the way they influence the inhabitants' thermal comfort, the causes of their impact on the constructions of the houses, and possible thermal-insulation methods that could be employed in order to prevent extremely hot air from infiltrating into the rooms, that are constantly air-conditioned, and increase the inside room temperatures, as well as try to describe and choose suitable thermal-insulation materials in order to decrease the air-conditioning devices needs which will help decrease electricity costs for air-conditioning devices function.

The Man-Made River Project in Libya is the latest attempt to save lives in North Africa

The Man-Made River Project in Libya is one of the giant and major projects in the world and is the largest channel for transporting about (6 million cubic meters) of water from the southern desert areas in Libya to the northern regions that overlook the coasts of the Mediterranean Sea, where most of the cities of Libya are concentrated, which suffer from Water scarcity. The project was implemented in five phases or systems

Field measurements of desert dust deposition in Libya

North Africa is the largest global source of atmospherically transported desert dust. Advances in satellite technology allow dust plumes to be spatially and temporally monitored, but little is known of near-surface dust deposition, as field-based studies are rare. This paper presents results from a year-long field-based dust monitoring study of three zones across Libya, ranging from the Mediterranean coast to the Sahara desert. Monthly deposition rates are compared with meteorological data, particle size distribution and mineralogy to establish potential source areas. Comparison of annual dust deposition rates with previous studies in North Africa shows that areas of Libya have the highest dust deposition rates on record.

Aeration and slow sand filtration in small systems

Abstract Treatment technologies for small systems should have lower construction and operation cost, lower maintenance and labor requirements as well. The quality of groundwater in the Fezzan area of Libya for drinking purposes is not acceptable when compared to the quality of standards given by WHO. Hence, the groundwater has to be treated before being used for drinking purposes. In the Sahara Desert there is a tremendous amount of sand which is suitable for slow sand filtration and rapid sand filtration within the water treatment objectives. In this study, the selected treatment system of the groundwater contains aeration and slow sand filtration units. This small system was constructed as a pilot plant at the campus of Higher Institute of Technology Brack‐Libya. This system which was installed and succesfully operated has been proved to be an effective and appropriate treatment technology. After these results, it has been shown that drinking water for the residential areas in the Al Shati region or any...

STUDIES ON LIBYAN HONEYS

ABSTRACTTen honey samples representing various floral types were obtained from different areas in Libya. Two other samples were obtained from hives, where bees were fed on sugar syrup and date syrup, respectively. The chemical composition and some characteristics of these samples were studied. The data obtained generally showed that the specifications of honeys produced in Libya conformed with those required for table honey. The application of thin‐layer chromatography on cellulose‐coated plates for the analysis of honey sugars yielded clear resolution and discrete spots. Some measures — such as high level of calcium, low level of potassium and UV‐absorption spectra of honeys were suggested to be used for identifying the sugar‐honeys and for ensuring the quality of blossom honeys. An attempt has been made to predict the granulation behavior of honeys and a derived regression formula was suggested.
