Degradation and energy performance evaluation of mono-crystalline photovoltaic modules in Egypt.

Degradation reduces the capability of solar photovoltaic (PV) production over time. Studies on PV module degradation are typically based on time-consuming and labor-intensive accelerated or field experiments. Understanding the modes and methodologies of degradation is critical to certifying PV module lifetimes of 25 years.

Molecular Identification, Pathogenesis, and Life Cycle of from Cattle () in New Valley Governorate, Egypt.

was identified by molecular methods from an intermediate host, cattle (), in El-Kharga, New Valley Governorate, Egypt, and its life cycle and pathogenicity were studied in the final host, dogs (). 600 slaughtered cattle aged 6-8 years (480/120 males/females) were included. In addition, three laboratory-bred, coccidian-free puppies aged 2-3 months were fed infected bovine muscles to locate the definitive host and analyze sporogony.

A unique case of multiple calvarial hemangiomas with one large symplastic hemangioma.

Background: Symplastic hemangioma is a benign superficial abnormal buildup of blood vessels, with morphological features which can mimic a pseudo malignancy. A few cases have been reported in the literature. We report here, a unique case of calvarial symplastic hemangioma, which is the first case in the calvarial region.

Dry eye in rheumatoid arthritis: relation to disease activity.

The aim of this study was to find the correlation between severity of dry eye and rheumatoid arthritis (RA) disease activity. Forty- two RA patients with dry eye were recruited from Rheumatology Outpatient Clinic in Minia University Hospital. Assessment of RA disease activity was performed using disease activity score (DAS-28).

Pulmonary Mucormycosis: A Case Report of a Rare Infection with Potential Diagnostic Problems.

Pulmonary mucormycosis is a relatively rare pulmonary fungal disease, which is difficult to diagnose early and lacks effective treatment. It is seen in patients with hematological malignancies, diabetes mellitus, and immunocompromised states. The diagnosis depends primarily on the detection of fungi in lung tissue.

Next generation DNA sequencing of atypical choroid plexus papilloma of brain: Identification of novel mutations in a female patient by Ion Proton.

Choroid plexus papilloma (CPP) is a rare benign tumor of the central nervous system that is usually confined to the cerebral ventricles. According to the World Health Organization, CPP corresponds to a grade I atypical CPP (a-CPP); however, it can become more aggressive and reach grade II, which can rarely undergo malignant transformation into a choroid plexus carcinoma (grade III). To the best of our knowledge, identification of these tumors mutations by next generation DNA sequencing (NGS) has not been yet reported.

Evaluation of patients with dry eye for the presence of primary or secondary Sjӧgren's syndrome.

Purpose: To assess the frequency of Sjӧgren's syndrome (SS), either primary or secondary to rheumatic disease, in a cohort of patients with aqueous-deficient dry eye and to determine the most accurate objective test for diagnosis of SS.

Methods: A total of 111 patients with dry eye were recruited from Minia University's ​Ophthalmology Outpatient Clinic (69 patients) and Rheumatology Outpatient Clinic (42 patients). The patients were screened for aqueous tear-deficient dry eye by abnormal test results of Schirmer test I (<10 mm) and tear-film break-up time (<10 seconds) in at least one eye.

Prevalence and associated risk factors of Toxocara infection in dogs in northern and southern Egypt.

Toxocariasis is a zoonotic disease with a worldwide distribution caused by the parasitic roundworms, Toxocara canis, commonly found in the intestine of dogs. Identification of frequent shedders for Toxocara canis eggs and the associated risk factors overwhelmingly remain an important cornerstone of conducting evidence-based deworming regimens to reduce the environmental contamination with the parasite eggs. The present study was undertaken to prevalence rate of shedding of Toxocara canis eggs in dogs in Egypt combined with the possible risk factors naturally associated with the infection A total number of 296 fecal samples of dogs were collected in the period from July 2016 to June 2017 and properly screened for the presence of possible infection with an.

Psychological affection in rheumatoid arthritis patients in relation to disease activity.

Rheumatoid arthritis (RA) is a common, systemic autoimmune disease characterized by persistent symmetric polyarthritis (synovitis). Anxiety and depression are common among patients with RA, compared to the general population and have been associated with increased pain, fatigue, physical disability and health care costs, and an overall reduced health-related quality of life. The aim of the present study was to assess the relation between psychological factors (anxiety and depression) and disease activity (and severity) parameters in RA patients.

infection in chronic kidney disease patients undergoing hemodialysis in Egypt.

Patients with chronic renal failure are more susceptible to infections due to acquired immunodeficiency caused by uremia. Parasitic infections are one of the significant causes of morbidity and mortality in those patients, So we aimed to assess the prevalence of spp. and other protozoan infections in patients undergoing hemodialysis in Qena Governorate, Upper Egypt.

First molecular characterization of spp. in cattle in Qena Governorate, Upper Egypt.

Cattle are intermediate hosts for several species with different definitive hosts. The present study, to our knowledge, is the first to determine the prevalence of infection and morphologically and molecularly identify species in cattle in Qena Governorate, Upper Egypt. The samples were collected from the heart and oesophagus muscles of 84 slaughtered cattle (76 males and 8 females) aged between 11 months and 3 years from slaughterhouses in different localities in Qena Governorate, Upper Egypt.

Pattern of Thyroid Lesions in Western Region of Saudi Arabia: A Retrospective Analysis and Literature Review.

Background: Ultrasonography (US) is being recognized as a traditional way of the diagnosis of various thyroid disorders, and this will help in detecting the thyroid tumors in early stage. Thyroid nodules are common and usually benign; steps to diagnose malignancy should include a careful clinical evaluation, laboratory tests, a thyroid US exam and a fine-needle aspiration (FNA) biopsy.

Methods: A total of 173 registered cases were used for analysis in this study.

A case of fatal gastrointestinal haemorrhage due to hyperinfection with .

is an intestinal nematode with a complex life cycle. It is usually asymptomatic in healthy host however it may be a life threatening condition in immunocompromised patients when hyperinfection is associated with disseminated disease. However, reports of gastric involvement are rare.

INCIDENTAL PARASITIC INFECTIONS IN SURGICALLY REMOVED APPENDICES: A RETROSPECTIVE ANALYSIS.

Numerous parasitic infections can cause inflammation of the appendix and can mimic appendicitis clinically. The diagnosis is generally achieved only after surgery. However early diagnosis through stool examination may prevent life-threatening complications.

Comparative immunohistochemical expression of β-catenin, EGFR, ErbB2, and p63 in adamantinomatous and papillary craniopharyngiomas.

Unlabelled: Craniopharyngiomas (CPs) are rare epithelial tumors located mainly in the sellar/parasellar region. CPs have been classified into histopathologically, genetically, clinically and prognostically two distinctive subtypes: adamantinomatous and papillary variants.

Aim: To determine the immunohistochemical expression of β-catenin, EGFR, ErbB2, and p63 in adamantinomatous and papillary CPs.
