PURPOSE The aim of the study was to create a predictive model of blastocyst development based on morphokinetic parameters of time-lapse embryoscope monitoring. METHODS Time-lapse recordings of 432 embryos (obtained from 77 patients), monitored in Embryoscope, were involved in the study. Patients underwent in vitro fertilization according to standard(More)
[21] provide the notation and terminology for this paper. 1. PRELIMINARIES The following four propositions are true: (1) Let L be an add-associative right zeroed right complementable non empty loop structure and p be a finite sequence of elements of the carrier of L. If for every natural number i such that i ∈ dom p holds p(i) = 0 L , then ∑ p = 0 L. (2)(More)
the terminology and notation for this paper. The following propositions are true: (1) For all natural numbers n, m such that n = 0 and m = 0 holds (n · m − n − m) + 1 0. (2) For all real numbers x, y such that y > 0 holds min(x,y) max(x,y) 1. (3) For all real numbers x, y such that for every real number c such that c > 0 and c < 1 holds c · x y holds y 0.(More)
The following propositions are true: (1) For every natural number n holds 0 − n = 0. (3) 1 Let D be a non empty set, p be a finite sequence of elements of D, and n be a natural number. If 1 ≤ n and n ≤ len p, then p = (p(n − 1)) p(n) (p n). Let us observe that every left zeroed add-right-cancelable right distributive left unital commuta-tive associative non(More)
OBJECTIVE Lymph node metastasis is a characteristic of malignant cancers and is observed more frequently in oesophageal cancer than in other digestive tract cancers, making it one of the most important prognostic factors. Vascular endothelial growth factors C (VEGF-C) and D (VEGF-D) are important lymphangiogenic factors in human cancers and(More)
OBJECTIVE The rs10757278, rs1333049 and rs4977574 are single nucleotide polymorphisms (SNPs) of chromosome 9p21 locus associated with a prevalence of acute coronary syndromes (ACS). Reports concerning their association with long-term outcome after an ACS are equivocal. The aim of our study was to investigate the association of the 9p21.3 locus with 5-year(More)
Thrombocytopenia in small for gestational age (SGA) newborns may be due to placental vascular pathology, fetal consumptive coagulopathy and platelet destruction, local imbalance of thromboxane A2 causing placental vasoconstriction and platelet aggregation. Thrombopoiesis in SGA newborns is poorly recognized. In 61 SGA newborns we evaluated(More)
In the paper some notions useful in formalization of [11] are introduced, e.g. the definition of the poset of subsets of a set with inclusion as an ordering relation. Using the theory of many sorted sets authors formulate the definition of product of relational structures. The terminology and notation used in this paper are introduced in the following In(More)
The epigenetic inactivation of tumor suppressor genes may play an important role in the development and progression of many cancer types, including lung cancer. Therefore, we investigated the association between the aberrant promoter methylation of 2 genes: the Death-Associated Protein Kinase (DAPK) and the Ras Association Domain Family 1A (RASSF1A) by(More)
