The current study aims to integrate the geochemical characteristics of the Oligocene shale source rock system, oil, condensate, and natural gas samples in the Oligocene sandstone reservoirs from three exploration wells located in the offshore Nile Delta, East Mediterranean Sea, using organic geochemistry and a 1D basin modeling scheme. The Tineh shales exhibit total organic carbon values ranging between 0.90 and 1.

Antibiotics Prophylaxis Practice in Arthroplasty Surgeries.

Background Infection in orthopedic surgery is one of the most dreaded complications. It is associated with prolonged morbidity, disability, and increased mortality. One of the cornerstones of the prevention of infections is antibiotic prophylaxis.

Novel use of a bronchoscope and bariatric needle holder for retrieval of retained intramedullary metalwork during total knee arthroplasty.

Retained metalwork during total joint arthroplasties usually occur from accidental misplacement of jig locking pins into the medullary canal via the aperture created for intramedullary referencing. They are associated with significant clinical and financial consequences for the patient, surgeon and health care provider. Hence the imperative to device methods to not only prevent their occurrence but reliably retrieve any trapped foreign body.

The plausible mechanisms of tramadol for treatment of COVID-19.

Currently, no single medication has been approved for the management of coronavirus disease-2019 (COVID-19) caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Therefore, drug repositioningby investigating the use of existing drugs for management of COVID-19 patients is considered a desperate need. Tramadol is a commonly prescribed analgesic drug for treatment of moderate to severe pain with less potential for dependence and respiratory depression.

Geochemical and organic petrographic characteristics of high bituminous shales from Gurha mine in Rajasthan, NW India.

A high bituminous shale horizon from the Gurha mine in the Bikaner sub-basin of the Rajasthan District, NW India, was studied using a collection of geochemical and petrological techniques. This study investigated the nature and environmental conditions of the organic matter and its relation to the unconventional oil-shale resources of the bituminous shale. The analyzed shales have high total organic carbon and total sulfur contents, suggesting that these shale sediments were deposited in a paralic environment under reducing conditions.

Quantitative hydro-geophysical analysis of a complex structural karst aquifer in Eastern Saudi Arabia.

The Umm er Radhuma (UER) Formation is a major karst aquifer in Saudi Arabia. This study investigated the hydraulic and petrophysical characteristics of the folded UER carbonate aquifer using integrated hydrological and geophysical logging datasets to understand its complex hydraulic setting as well as detect possible water flow. Petrophysical analysis showed that the UER aquifer has three zones with different lithologic and hydraulic properties.

Characterization of a fractured basement reservoir using high-resolution 3D seismic and logging datasets: A case study of the Sab'atayn Basin, Yemen.

The Sab'atayn Basin is one of the most prolific Mesozoic hydrocarbon basins located in central Yemen. It has many oil producing fields including the Habban Field with oil occurrences in fractured basement rocks. A comprehensive seismic analysis of fractured basement reservoirs was performed to identify the structural pattern and mechanism of hydrocarbon entrapment and reservoir characteristics.

Assessing the hydrogeochemical processes affecting groundwater pollution in arid areas using an integration of geochemical equilibrium and multivariate statistical techniques.

Rapid economic expansion poses serious problems for groundwater resources in arid areas, which typically have high rates of groundwater depletion. In this study, integration of hydrochemical investigations involving chemical and statistical analyses are conducted to assess the factors controlling hydrochemistry and potential pollution in an arid region. Fifty-four groundwater samples were collected from the Dhurma aquifer in Saudi Arabia, and twenty-one physicochemical variables were examined for each sample.

The main complaints was abdominal discomfort, pain, tensmus and bleeding per rectum, which progressive decreased after PZQ.

Treatment of cutaneous leishmaniasis patients with pentostam via intralesion infiltration.

Cutaneous leishmaniasis (CL) is an endemic disease in Egypt. Systematic treatment with pentostam has its disadvantages and contraindications. In this study, six out of eight parasitologically proved CL patients recovered with intralesion infiltration with a dose of pentostam ranged between 0.

Changes in the spike activity of neurons in the ventrolateral nucleus of the thalamus in humans during performance of a voluntary movement.

The responses of neurons in the ventrolateral nucleus (VL) of the thalamus were studied in humans during performance of voluntary motor tests; recordings were made with microelectrodes during stereotaxic operations in patients with Parkinson's disease. Two previously classified types of polyvalent neurons (A, B) were found to show different patterns of responses during the functional stages of carrying out a voluntary movement (preparation, initiation, performance). A and B neurons showed concordant changes in the dynamics of ongoing network activity in the form of linked (activation-inhibition) and synergic (activation) response patterns, correlating with the preparation-trigger and performance phases of movements.

[Changes in the impulse activity of neurons of the human thalamic ventrolateral nucleus during voluntary movement].

Functional differences were revealed in evoked activity of two types (A and B) of units of the human thalamic ventro-lateral nucleus (VL). Collective activities of these polyfunctional neurons were selectively related to triggering and execution phases of movement. Common character of dynamics of the responses seems to be due to similar polyfunctional nature as well as to the functional role of these two complementary elements in the motor signal transmission.

Intestinal parasites among food-handlers in Qualyobia Governorate, with reference to the pathogenic parasite blastocystis hominis.

A total of 1700 male food handlers, above 20 years of age who came for health clearance certificate were the subjects of the present study.

Toxoplasma antibodies were detected in sera of 700 cases; 500 were collected randomly from individuals attending the outpatient clinics of Benha University Hospitals of different ages and sexes and 200 from suspected inpatients from Obstetric, Opthalmology, Internal Medicine and Surgery Departments. The indirect fluorescent antibody technique was performed. The results were correlated with the clinical picture, age, sex and residence.

Leishmania major in an Egyptian patient manifested as diffuse cutaneous leishmaniasis.

Diffuse cutaneous leishmaniasis (DCL) is an unusual form of cutaneous leishmaniasis mainly caused by infection with Leishmania aethiopica in the Old World. In this paper, diffuse cutaneous leishmaniasis was reported for the first time, in an Egyptian patient from Sinai Peninsula resulting from infection with L. major zymodeme LOND-1 as proved by enzymatic characterization, using seven enzymes.

Unit activity in human thalamic reticularis nucleus. I. Spontaneous activity.

Microelectrode recording was carried out in the thalamic reticularis nucleus (Rt) during 51 stereotaxic operations performed in locally anesthetized dyskinetic patients. The spontaneous activity (SA) of 426 units was studied by means of computer processing techniques. Three types of unit (A, B, C) were shown to exist in Rt: with irregular low-frequency (0-10/sec) discharges (A type, 51%); bursting in short trains (10-30 msec) with unstable rhythmic pattern (2-5/sec; B type, 42%); presenting long duration (0.
