the aim of this study was to evaluate the effects of the addition of antioxidants (vitamin e, β- mercaptoethanol and their combination) to semen extender.  progressive motility, viability and ph of fresh ram semen were examined. ejaculate samples were collected with artificial vagina from three ghezel-merinose rams (3 years old) during non- breeding reproduction season. semen was diluted with a...

OBJECTIVE To compare the effects of general anesthesia combined with epidural preemptive analgesia with general anesthesia on stress reaction in the retroperitoneal laparoscopic surgery. METHODS Forty patients with adrenal tumors undergoing retroperitoneal laparoscopic surgeries were randomly assigned into general anesthesia combined with epidural preemptive analgesia group (GE) and general a...

The objective of this study was to examine the post-thaw effects of three cryoprotective extenders (Tris-fructose-citric acid extender, Tris-glucose-citric acid extender, and lactose extender), three linear freezing rates (-1, -6, and -20 degrees C/min), and three thawing rates (37 degrees C water bath for 120s, 60 degrees C water bath for 30s, and 70 degrees C water bath for 8s) on coyote sper...

I prove that there is a recursive function T that does the following: Let X be transitive and rud closed, and let X ′ be the closure of X ∪{X} under rud functions. Given a Σ0 formula φ(x) and a code c for a rud function f , T (φ, c, ~x) is a Σω formula such that for any ~a ∈ X, X ′ |= φ[f(~a)] iff X |= T (φ, c, ~x)[~a]. I make this precise and show relativized versions of this. As an applicatio...

Ejaculates from 7 stallions were split and simultaneously frozen in three different extenders, INRA 96 egg yolk glycerol, Ghent and the newly developed extender Caceres. After thawing, samples were evaluated for motility (CASA system) sperm membrane integrity and early membrane changes (YoPro-1/Eth staining), acrosome integrity (FICT-PNA), and mitochondrial membrane potential (JC-1) (flow cytom...

The aims were to evaluate the suitability of a non-commercial TRIS-lecithin (LC) extender and the effect of different concentrations of catalase (CAT) on motility, capacitation status (Chlortetracycline-assay) and zona pellucida (ZP) binding capacity of canine spermatozoa stored at +5 degrees C for 4 days. The sperm-rich fractions of the ejaculates of four stud dogs were divided into four aliqu...

this study was carried out to investigate effects of copper sulphate (cuso4) additive to semen extenders on sperm parameters: progressive motility, viability, membrane integrity and dna damage, after semen dilution and cryopreservation. semen samples of 5 buffalo bulls of 3-5 years old were collected at 5 different occasions during the autumn 2011. a total number of 25 samples were used in each...

We define "extenders" as a class of robot manipulators worn by humans to augment human mechanical strength, while the wearer's intellect remains the central control system for manipulating the extender. Our research objective is to determine the ground rules for the design and control of robotic systems worn by humans through the design, construction, and control of several prototype experiment...

This study was conducted to assess the physical and morphological characteristics of fresh, pre-freeze and post-thaw black Bengal buck (Capra hircus) semen processed in Tris-egg yolk-citrate-fructose-glycerol (TEYCFG) extender containing 4 different concentrations (2.5, 5, 7.5 and 10%) of egg-yolk. Ejaculates were collected once a week for eight weeks from six mature bucks (48 ejaculates) using...
