Effects of norethisterone acetate on the performance of female racing Greyhounds.

A comparison between the performance of spayed female racing Greyhounds and those suppressed with norethisterone acetate (NTA) was made. Previous work by the author has shown that the racing performance of spayed bitches is the same as that of entire bitches in anoestrus, i.e.

Risk of iatrogenic damage to the sciatic nerve in dairy cattle.

Sciatic nerve damage in cattle could lead to pain, paralysis and lameness, creating welfare and productivity issues. Damage following intramuscular injection is highlighted in some clinical texts although there is no indication of prevalence. This cross-sectional study investigated the anatomical size and position of the sciatic nerve in four dairy cattle type cadavers.

An NPF transporter exports a central monoterpene indole alkaloid intermediate from the vacuole.

Plants sequester intermediates of metabolic pathways into different cellular compartments, but the mechanisms by which these molecules are transported remain poorly understood. Monoterpene indole alkaloids, a class of specialized metabolites that includes the anticancer agent vincristine, antimalarial quinine and neurotoxin strychnine, are synthesized in several different cellular locations. However, the transporters that control the movement of these biosynthetic intermediates within cellular compartments have not been discovered.

The effect of spaying on the racing performance of female greyhounds.

The effect of spaying (ovariohysterectomy) on racing greyhound performance was analysed. Using data from a longitudinal observational study design, random effects models were used to compare the racing performance before and after spaying. Greyhounds were matched by distance and date of racing, and then both spayed and entire bitches were compared for each stadium which had spayed greyhounds on the racing strength.

The effect of dioestrus on the racing performance of Greyhounds.

The degree of performance change during the dioestrus of racing Greyhounds has long been the subject of debate. Assessments have previously been on a qualitative basis. The analyses in this paper are unique and produce a quantitative assessment of the change in performance during dioestrus.
