Background: Dirofilaria immitis is a cosmopolitan zoonotic, vector-borne parasite of carnivorous animals causing dirofilariasis in human beings. Common commercial serodiagnostic tests for canine dirofilariasis usually lead to different results in their sensitivity and specificity. The present study reports development of recombinant DgK (rDgK) antigen of D. immitis for accurate immunodiagnosis of D. Immitis-infected dogs using indirect ELISA test. Methods: The rDgK coding sequence was successfully sequenced, codon optimized and cloned in pET-24a(+) expression vector and then expressed in Escherichia coli...

Head trauma is one of the leading causes of death and disability worldwide. Combined head lesions consist of more than one form of lesions. Biochemical markers of brain injury are used in determining the extent of brain injury and predicting its outcomes. The aim of this study was to investigate the forensic and clinical significance of serum amylase, lipase and gamma glutamyl transferase (GGT) as predictors of the outcome in head injured patients. PATIENTS AND METHODS: Sixty head injured patients were enrolled and subjected to personal history taking, general and local physical examination...

Combretastatin A4 (CA4) is a natural product characterized by a powerful inhibition of tubulin polymerization and a potential anticancer activity. However, therapeutic application of CA4 is substantially hindered due to geometric isomerization. In the current study, new cis-restricted Combretastatin A4 analogues containing 1,2,4-triazle in place of the olefinic bond were designed and synthesized. The synthesized compounds were evaluated for their in vitro antiproliferative activity in human hepatocellular carcinoma HepG2 and leukemia HL-60 cell lines using MTT assay...

The emergence of the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) infections has become a global issue of dire concerns. MERS-CoV infections have been identified in many countries all over the world whereas high level occurrences have been documented in the Middle East and Korea. MERS-CoV is mainly spreading across the geographical region of the Middle East, especially in the Arabian Peninsula, while some imported sporadic cases were reported from the Europe, North America, Africa, and lately Asia...

PURPOSE OF REVIEW: There are a limited number of studies investigating the association between the microbiome and HIV. Although the majority of these published investigations have focused on the role of the bacterial community (bacteriome) in this setting, a handful of studies have also characterized the role of the mycobiome in HIV-infected individuals. This review will summarize the most recent reports pertaining to the role of the fungal community in HIV. RECENT FINDINGS: Differences in the composition of the oral and respiratory mycobiome in HIV-infected individuals compared with uninfected individuals have been reported...

BACKGROUND: Variations in gut microbiota composition and diversity have been associated with childhood adiposity, although most studies describing this have been cross-sectional in nature. Our objective was to evaluate associations between body weight and the gut microbiota over time in obese preschool-age children. METHODS: Obese, preschool-age, Hispanic children provided stool samples at baseline and following a 6-month behavioral intervention. Normal-weight (NW) children also provided stool samples...

AIM: A new series of pyrazolo[1,5-c]pyrimidines were synthesized by different hybridization strategies. METHODOLOGY: All structures were confirmed by IR, (1)H, (13)C, (1)H-(13)C heteronuclear multiple-quantum correlation (HMQC) spectra and microanalysis. They were evaluated for their in vitro antileishmanial activity against miltefosine and amphotericin B deoxycholate as reference drugs. RESULTS: The most active compounds 2a and 9a demonstrated superior potencies to miltefosine by ten- and six-fold, respectively, for the promastigote form, and by 5...

In this Letter, we present a tunable Y-branch hybrid master oscillator power amplifier (MOPA) with 5.5 W output power, emitting between 973.7 and 983.4 nm. The MO is a monolithic Y-branch distributed Bragg reflector (DBR) diode laser, which is collimated and coupled into a tapered amplifier using cylindrical microlenses in a compact 25  mm×25  mm conduction cooled laser package. The wavelength spacing between the two laser branches is 2.2 nm. Each branch can be electrically tuned by up to 7.5 nm of quasi-continuous wavelength tuning, which in combination covers up to 9...

New 1-arylamidebiguanide hydrochloride salts were synthesized via reaction of hydrazide derivatives with dicyandiamide in acidic medium. The structure of the obtained derivatives was characterized by spectroscopic and elemental analysis tools. The anti-diabetic properties of the synthesized compounds were determined. Oral treatment of hyperglycemic rats with the synthesized biguanide derivatives showed a significant decrease of the elevated glucose in comparison with the anti-diabetic standard drug, metformin...

Sleep deprivation is a common health problem that is growing rapidly worldwide and it is associated with short- and long-term impacts on health. The aim of this study was to detect potential predictors of salivary testosterone (sT) association with sleep deprivation in Arab male university students. In this prospective cohort study, 77 university male students in the age range of 18 to 26 years were divided into two groups, sleep-deprived (SD) participants and non-sleep-deprived (NSD) participants. Sleep deprivation was defined as sleeping less than 5 hr per night...

The growth of administrative data repositories worldwide has spurred the development and application of data quality frameworks to ensure that research analyses based on these data can be used to draw meaningful conclusions. However, the research literature on administrative data quality is sparse, and there is little consensus regarding which dimensions of data quality should be measured. Here we present the core dimensions of the data quality framework developed at the Manitoba Centre for Health Policy, a world leader in the use of administrative data for research purposes, and provide examples and context for the application of these dimensions to conducting data quality evaluations...

Considerable attention has been paid to the introduction of novel naturally occurring plant-derived radiosensitizer compounds in order to augment the radiation efficacy and improve the treatment outcome of different tumors. This study was therefore undertaken to evaluate the antitumor, antiangiogeneic, and synergistic radiosensitizing effects of apigenin, a dietary flavonoid, and/or cryptotanshinone, a terpenoid isolated from the roots of Salvia miltiorrhiza, against the growth of solid Ehrlich carcinoma in female mice...

This study aimed to explore whether genetic polymorphisms in vitamin D receptor are correlated to the breast cancer prevalence in an Egyptian population. Polymerase chain reaction-restriction fragment polymorphism was used to genotype three frequently analyzed vitamin D receptor gene single-nucleotide polymorphisms (rs1544410, rs7975232, and rs731236) and were identified by sequencing analysis. This is the first study that recorded a new single-nucleotide polymorphism in ApaI genotype within an Egyptian population and was registered with the accession number KY859868...

Cardiomyopathy is a serious complication of diabetes mellitus and occurs independently of coronary artery disease or hypertension. It manifests as systolic/diastolic dysfunction and hypertrophy of the left ventricle and can lead to heart failure. Hyperglycemia can trigger a series of maladaptive stimuli and result in cardiac hypertrophy, fibrosis and reduced performance and contractility. The pathogenesis of diabetic cardiomyopathy is a multifactorial process that includes metabolic derangements such as increased oxidative stress, and altered non-oxidative glucose pathways and lipid metabolism...
