Anti-Müllerian hormone (AMH) has gained increasing interest as a biomarker for assessment of gonadal activity. The ability to predict the ovarian follicular reserve of prepubertal female horses (fillies) or to identify stallions with testicular pathologies already during their prepubertal life has not been analyzed so far. Both would help to select fertile horses and reduce costs associated with keeping animals. The objectives of the present study were to (1) assess AMH, LH, FSH, progesterone (females) and testosterone (males) dynamics in prepubertal horses from birth onwards and (2) determine whether AMH concentrations detected in plasma of prepubertal female and male horses are correlated with postpubertal gonadal development...

Seminal plasma (SP) contains proteins that may influence cryosurvival and prevent capacitation-like changes due to freezing and thawing. The objective of this study was to investigate the effect of adding pooled SP from "good" (GF) or "bad" (BF) freezer stallions on sperm cells' fertilizing ability. "Good freezers" refers to stallions that usually produce ejaculates which can withstand cryopreservation, whilst "bad freezer" stallions produce ejaculates which cannot tolerate the freezing process...

The study introduces an analytical platform for the detection of genes or aptamer-ligand complexes by nucleic acid barcode patterns generated by DNA machineries. The DNA machineries consist of nucleic acid scaffolds that include specific recognition sites for the different genes or aptamer-ligands analytes. The binding of the analytes to the scaffolds initiate, in the presence of the nucleotide mixture, cyclic polymerization/nicking machinery that yields displaced strands of variable lengths. The electrophoretic separation of the resulting strands provides barcode patterns for the specific detection of the different analytes...

Pseudomonas aeruginosa is a bacterial pathogen that causes life-threatening infections in immunocompromised patients. It produces a large armory of saturated and mono-unsaturated 2-alkyl-4(1H)-quinolones (AQs) or AQ N-oxides (AQNOs) that serve as signaling molecules to control the production of virulence factors, are involved in membrane vesicle formation and iron chelation and also have e.g. antibiotic properties. It has been shown that the FabH-like heterodimeric enzyme PqsBC catalyzes the last step in the biosynthesis of the most abundant AQ congener 2-heptyl-4(1H)-quinolone (HHQ) by condensing octanoyl-coenzyme A (CoA) with 2-aminobenzoylacetate (2-ABA), but the basis for the large number of other AQs/AQNOs produced by P...

The molybdenum cofactor (Moco) is a redox-active prosthetic group found in the active site of Moco- dependent enzymes, which are vitally important for life. Moco biosynthesis involves several enzymes that catalyze the subsequent conversion of GTP to cyclic pyranopterin monophoshpate (cPMP), molybdopterin (MPT), adenylated MPT (MPT-AMP) and finally Moco. While the underlying principles of cPMP, MPT, and MPT-AMP formation are well-understood, the molybdenum insertase (Mo-insertase) catalyzed final Moco maturation step is not...

BACKGROUND: Accumulating evidence suggests serum levels of microRNA (miR)-371a-3p to be a novel tumour marker of testicular germ cell tumours (GCTs). Presently, there is only limited information regarding the velocity of decline of serum levels in response to treatment. PATIENTS AND METHODS: Twenty-four patients with testicular GCT (20 seminoma, 4 nonseminoma, median age 40 years) with clinical stage 1 had measurements of serum levels of miR-371a-3p preoperatively and repeatedly on the following 3 days...

BACKGROUND: Childhood solar ultraviolet radiation (UVR) exposure increases the risk of skin cancer in adulthood, which is associated with mutations caused by UVR-induced cyclobutane pyrimidine dimers (CPD). Solar UVR is also the main source of vitamin D, essential for healthy bone development in children. OBJECTIVES: The impact of a 12-day Baltic Sea (54o N) beach holiday on serum 25-dihydroxyvitamin D (25(OH)D3 ) and CPD was assessed in 32 healthy Polish children (skin types I-IV)...

BACKGROUND: Conventional photodynamic therapy (PDT) is associated with side effects, primarily related to the waiting time between pre-treatment with application of photosensitizer and illumination. Pain during illumination is a major issue for the patients and options for effective pain relief are limited. Post-treatment inflammation can often be severe and cause inconvenient down-time for the patients and their employers. METHODS: To avoid the problems of pain and patients crowding in the clinic we eliminated red light treatment of high PpIX concentration and introduced illumination in daylight which may be performed at home...

Ergothioneine is an emerging factor in cellular redox homeostasis in bacteria, fungi, plants, and animals. Reports that ergothioneine biosynthesis may be important for the pathogenicity of bacteria and fungi raise the question as to how this pathway is regulated and whether the corresponding enzymes may be therapeutic targets. The first step in ergothioneine biosynthesis is catalyzed by the methyltransferase EgtD that converts histidine into N-α-trimethylhistidine. This report examines the kinetic, thermodynamic and structural basis for substrate, product, and inhibitor binding by EgtD from Mycobacterium smegmatis...

Attentional focus research suggests an external focus leads to improved motor performance compared to an internal focus (Wulf in Int Rev Sport Exerc Psychol 6:77-104, 2013), but skilled athletes often report using an internal focus (Fairbrother et al., Front Psychol 7:1028, 2016) and sometimes shifting between different foci in the preparation and execution phases of performance (Bernier et al. in J Appl Sport Psychol 23:326-341, 2011; Bernier et al. in Sport Psychol 30:256-266, 2016). To date, focus shifts have been unexplored in experimental research, thus the purpose of this study was to determine the effect of shifting focus between the preparation and execution phases of a standing long jump...
