Haemonchus contortus is a major parasite of small ruminants and its blood-feeding behaviour causes effects ranging from mild anaemia to death. Knowledge of the genetic variation within and among H. contortus populations can provide the foundation for understanding transmission patterns and aid in the control of haemonchosis. Adult male H. contortus were collected from three geographical regions in Egypt. The second internal transcribed spacer (ITS2) of nuclear ribosomal DNA was amplified using the polymerase chain reaction (PCR) and sequenced directly...

The impact of post-synthesis processing in reduced graphene oxide materials for supercapacitor electrodes has been analyzed. A comparative study of vacuum, freeze and critical point drying was carried out for hydrothermally reduced graphene oxide demonstrating that the optimization of the specific surface area and preservation of the porous network are critical to maximize its supercapacitance performance. As described below, using a supercritical fluid as the drying medium, unprecedented values of the specific surface area (364 m(2) g(-1)) and supercapacitance (441 F g(-1)) for this class of materials have been achieved...

BACKGROUND: Panicum turgidum, desert grass, has not reported any detailed phytochemical or biological study as yet. OBJECTIVE: To establish P. turgidum secondary metabolite profile and to assess its antihepatotoxic effect. MATERIALS AND METHODS: Ultra-performance liquid chromatography (UPLC) coupled to quadrupole high-resolution time of flight mass spectrometry (qTOF-MS) was used for large-scale secondary metabolites profiling in P. turgidum extract, alongside assessing median lethal dose (LD50) and hepatoprotective effect against carbon tetrachloride (CCl4) intoxication...

Introducción: la gestación y lactancia están relacionadas con pérdidas temporales en la densidad mineral ósea (DMO) materna. Una suplementación con calcio podría resultar beneficiosa para evitar la pérdida de masa ósea del esqueleto materno. Otros nutrientes como los prebióticos han sido identificados como responsables de un incremento en la absorción de minerales, pudiendo condicionar la mineralización ósea.Objetivo: estudiar el efecto de la suplementación de la dieta materna con el prebiótico inulina enriquecida con oligofructosa, durante la gestación y la lactancia sobre el contenido mineral óseo (CMO) y la DMO al final del periodo de lactancia...

In pesticide residue analysis, relatively low-sensitivity traditional detectors, such as UV, diode array, electron-capture, flame photometric, and nitrogen-phosphorus detectors, have been used following classical sample preparation (liquid-liquid extraction and open glass column cleanup); however, the extraction method is laborious, time-consuming, and requires large volumes of toxic organic solvents. A quick, easy, cheap, effective, rugged, and safe method was introduced in 2003 and coupled with selective and sensitive mass detectors to overcome the aforementioned drawbacks...

During the cell cycle, cyclin dependent kinase 1 (CDK1) and protein phosphatase 2A (PP2A) play major roles in the regulation of mitosis. CDK1 phosphorylates a series of substrates triggering M-phase entry. Most of these substrates are dephosphorylated by PP2A. To allow phosphorylation of CDK1 substrates, PP2A is progressively inactivated upon M-phase entry. We have shown previously that the interplay between these two activities determines the timing of M-phase entry. Slight diminution of CDK1 activity by the RO3306 inhibitor delays M-phase entry in a dose-dependent manner in Xenopus embryo cell-free extract, while reduction of PP2A activity by OA inhibitor accelerates this process also in a dose-dependent manner...

: The aim of this study was to review the outcome of the treatment of finger proximal interphalangeal joint dorsal fracture subluxations and pilon fractures with a modified external fixator. We treated 36 patients (36 fingers). We assessed the ranges of motion and patient satisfaction. At final follow-up, 23 patients had no pain; 11 had pain in the cold; and two also had mild pain. None had moderate or severe pain. The mean range of proximal interphalangeal joint motion was 86° (60°-100°)...

The objective of the present study was to estimate the seroprevalence of Brucella spp. in humans and cattle at Sharkia Governorate, Egypt. In addition, identification of Brucella spp. in milk samples by PCR and culture with the evaluation of the risk factors associated with Brucella spp. seroprevalence in humans were carried out. Overall, the seroprevalence of Brucella antibodies in the examined cattle was 23.8%, while in human participants it was 21%. The examination of 205 milk samples using PCR revealed that 6...

Calea urticifolia (Asteraceae: Asteroideae) has long been used as a traditional medicine in El Salvador to treat arthritis and fever, among other illnesses. The chloroform extract of the leaves of C. urticifolia showed potent inhibition of recombinant human monoamine oxidases (MAO-A and -B). Further bioassay-guided fractionation led to the isolation of a flavonoid, acacetin, as the most prominent MAO inhibitory constituent, with IC50 values of 121 and 49 nM for MAO-A and -B, respectively. The potency of MAO inhibition by acacetin was >5-fold higher for MAO-A (0...

Exciting advances are revealing that breast milk harbors populations of stem and progenitor cells, and much attention is now intensified on delineating their properties and functions. The aim of this study is to isolate a mesenchymal stem cell (MSC)-like population from rabbit breast milk and track their integration into the different organs of the breastfed rabbits after taken by oral route and to explore the functional role of stem cells in the breastfed newborn babies. Ten newborn rabbits 2 weeks old fed on 2 × 10(6) PKH26-labeled rabbit milk derived-MSCs suspended in 2 mL Dulbecco's modified Eagle's medium (DMEM) and 10 newborn baby rabbits fed with 2 mL DMEM solution or with rabbit fibroblasts as a control group were used in the study...

Three different spectrophotometric and two spectrofluorimetric methods have been developed and validated for the determination of vincamine (VN) and naftidrofuryl oxalate (NF) in tablets. The spectrophotometric methods depend on charge transfer complex formation between each of VN and NF with 7,7,8,8-tetracyano-quinodimethane (TCNQ), 2,6-dichloroquinone-4-chloroimide (DCQ) and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) at 843, 580 and 588 nm, respectively. The spectrofluorimetric methods are based on the formation of charge transfer complex between each of the two drugs and TCNQ, with measurement of the fluorophore formed at 312/375 and 284/612 nm, respectively, or with DDQ at 400/475 and 284/396 nm, respectively...

Immune reconstitution following hematopoietic stem cell transplantation (HCT) beyond one year is not completely understood. Many transplant recipients who are free of graft versus host disease (GVHD) and not receiving any immunosuppression more than a year after transplant seem to be able to mount appropriate immune responses to common pathogens and respond adequately to immunizations. However, two large registry studies over the last two decades seem to indicate that infection is a significant cause of late mortality in some patients, even in the absence of concomitant GVHD...

BACKGROUND: Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Small, noninflamed acne lesions may not be more than a slight nuisance, but, in individuals with more severe inflammatory disease, pain, social embarrassment, and both physical and psychological scarring can be life altering. Despite its high prevalence, no previous community-based studies have been conducted in Arar, northern border of Kingdom of Saudi Arabia, addressing this issue...

BACKGROUND: Dysmenorrhea is one of the most common and important health problems, especially among young girls. It results in absence from school and work. It has some negative effects on the daily activities of patients. Because of cultural problems, patients ordinarily do not seek help from others in this situation. Identification of abnormal menstrual patterns during adolescence may permit early prevention of potential health concerns in adulthood. OBJECTIVES: The aim of this study was to determine the prevalence, severity, and impact of dysmenorrhea in secondary-school students and its association with school absenteeism in Arar city...
