The effects of a hepaticoactivator, diisopropyl 1, 3-dithiol-2-ylidene malonate (NKK-105), on motoricity and EEG were observed int he rat, mouse, cat and man. NKK-105 suppressed the effects of ethanol (1,000-3,000 mg/kg, p.o., in mice and rats), e.g. the blood alcohol concentration of NKK-105 treated subjects was significantly lower than that of untreated controls. NKK-105, in 100-300 mg/kg p.o...

This study tested different concentrations of egg yolk in canine freezing extender void of glycerol, a commonly used cryoprotectant, by examining the motility and morphology throughout the freezing process: initial (baseline after extender added), post-cool (after three hours at 5°C) and post-thaw (after freezing.) Initial values of pH, osmolarity, motility and morphology were obtained for comp...

The purpose of this study was to evaluate the probable effects of leptin addition in different levels to the semen extender on sperm quality (motility and motility parameters, viability, sperm membrane integrity, and DNA damage). Semen specimens were evaluated immediately after leptin addition, equilibration time and after thawing the frozen semen. Five healthy buffalo bulls (5 ejaculates from ...

The paper is a continuation of [Gi]. Extending the methods of [Gi] we show the following: Let κ = ⋃ n<ω κn, κ0 < κ1 < · · · < κn < · · · (1) if each κn carries an extender of the length of the first Mahlo above κn, then for every λ > κ there is a generic extension satisfying 2 ≥ λ; (2) if each κn carries an extender of the length of the first fixed point of the א-function above κn of order n, t...

Cryopreservation of semen from the Caspian brown trout (Salmo trutta caspius) and effects of extender type, freezing and thawing rates on fertilization ability were studied. After assessment of semen quality, one part of semen was diluted with three parts of different extender and decanted into 0.5ml straws. Freezing was carried out at two freezing levels, 1.5cm and 2cm above surface of liquid ...

Two experiments were designed to evaluate the effects of the amino acids glycine and cysteine on cryopreservation of ram spermatozoa. After primary evaluation of collected ejaculates, the semen samples were pooled and diluted 1:4 before cooling (experiment 1) and freezing (experiment 2) with Tris-Citrate-Fructose-Yolk (TCFY) extender supplemented with different concentrations of glycine and cys...

Fertility of frozen-thawed bull sperm is reduced by cryopreservation. Freezing-thawing procedures can result in as much as a sevenfold fertility decrease. Sperm mortality and loss of motility do not fully explain the reduced fertility of cryopreserved semen; they may be partially explained by the loss of sperm surface proteins, which are necessary for fertilization. We have previously identifie...

Extender based forcings are studied with respect of adding branches to Aronszajn trees. We construct a model with no Aronszajn tree over אω+2 from the optimal assumptions. This answers a question of Friedman and Halilović [1]. The reader interested only in Friedman and Halilović question may skip the first section and go directly to the second. 1 No branches to κAronszajn trees. We deal here wi...
