A total number of 300 females and 30 males of two experimental broiler lines, TT (male) and PP (female), with 39 and 36 weeks of age, respectively. Experiment 1 (TT) evaluated the effect of storage time (ST) on hatchability and embryo mortality (EM). Eggs were stored for 2 (ST1), 4 (ST2), 6 (ST3), 8 (ST4), 10 (ST5), 12 (ST6), and 24 (ST7) days and EM was assessed in the periods of 0 to 6 (EM1),...

BACKGROUND Blastocystis sp. are among the most commonly observed intestinal parasites in routine clinical parasitology. Blastocystis in humans consists of at least 9 genetic subtypes. Different subtypes of Blastocystis may be associated with differences in pathogenicity and symptomatology. METHODS Advanced microscopy on two samples and sequence-confirmed PCR on a third sample from the same in...

The ability of insulin-like growth factor-1 (IGF-1) to regulate surface expression of the interferonreceptor 2 (IFNR2) transducing chain and activation of IFN– induced signal transducer and activator of transcription-1 (STAT-1) in human T cells was analyzed. We show that, especially in the absence of serum (which contains IGF-1), IGF-1 down-regulated surface expression of the IFNR2 chain and in...

Mutations identified in zebrafish genetic screens allow the dissection of a wide array of problems in vertebrate biology. Most screens have examined mutations induced by treatment of spermatogonial (premeiotic) cells with the chemical mutagen N-ethyl-N-nitrosourea (ENU). Treatment of postmeiotic gametes with ENU induces specific-locus mutations at a higher rate than premeiotic regimens, suggest...

Thyroid hemiagenesis (THA) is a rare congenital anomaly. It occurs more frequently in the left lobe and predominantly in women. Most of the cases are asymptomatic. The most frequent associated thyroid disorders with THA are nontoxic nodular goiter and Hashimoto's thyroiditis whereas association of Graves' disease with THA is very rare. We present a man patient with THA and multinodular Graves' ...

Changes in the chemical composition and antioxidant activity of flaxseed hull during maturation were investigated. P129 hull variety was studied at four maturation stages (St1, St2, St3, and St4). Significant variation in proximate composition and flaxseed hull oil characteristics were observed. A significant increase in the carbohydrates content of the hull was observed during development. The...

Complete mitochondrion-related organelle (MRO) genomes of several subtypes (STs) of the unicellular stramenopile Blastocystis are presented. Complete conservation of gene content and synteny in gene order is observed across all MRO genomes, comprising 27 protein coding genes, 2 ribosomal RNA genes, and 16 transfer RNA (tRNA) genes. Despite the synteny, differences in the degree of overlap betwe...

Aim: The aim of this study was to verify the pain behavior to electroacupuncture (EACP) in rabbit tooth-pulp assay. Methods: Albino rabbits weighing 1.5-2.0 kg) were pretreated with saline or morphine (5mg/kg, e.v.) 10 min before the nociceptive test (NT). In another group, EACP (rectangular pulses, f1=2 Hz, f2=0.1 s, 3 mA) was applied in acupoints and sham points, before and during the NT. Aft...

Information about livestock carrying methicillin-resistant coagulase-negative staphylococci and mammaliicocci (MRCoNS/MRM) is scarce. The study was designed to gain knowledge of the prevalence, phenotypic genotypic antimicrobial resistance genetic diversity MRCoNS/MRM originating from ruminants New World camelids. In addition, a multi-locus sequence typing scheme for characterization Mammaliico...

Abstract Introduction Simulation is an established training modality, though its use in high-stakes assessment under-explored. This study sought to develop and validate a novel of operative competence for higher specialist trainees general surgery. Methods Content validity was derived from previously conducted Delphi consensus trainers. Eight stations were created using combination virtual real...
