Dairy cattle metabolic disorders, which are diseases related to disturbance of one or more metabolic processes in the organism are discussed in this overview. The transition period which includes three weeks before and three weeks after parturition is very critical for dairy cows. This period of time is associated with multiple changes including hormonal changes, moving from non-lactating to la...

The effect of bovine pineal extract and light duration on lactation in mice was examined in two experiments. In Exp. I, groups of lactating mice were injected intraperitoneally with 0, .5, 1.0, 2.0 and 4.0 mg extractable protein from a bovine pineal crude extract. The highest dose level was equal to .14 g of pineal tissue. Neither lit ter (eight pups per litter) weight gains, which were used as...

Previous investigations have shown that the lipid composition of cerebral membranes and dopaminergic neurotransmission are changed under chronic α-linolenic acid-diet deficiency in the rat. This study investigated whether these changes could be reversed and if the stage of brain maturation might play a role in the recovery process. The effects of reversion on the fatty acid composition and dopa...

OBJECTIVES To determine the microbiological profile of breast abscess and assess the antibiotic susceptibility of the causative agents. MATERIALS AND METHODS Data obtained from cases of breast abscess over a period of 3.5 years, June 2006 to December 2009, were retrospectively analyzed. Specimens were cultured using optimal aerobic and anaerobic microbiological techniques. The antibiotic susc...

This investigation summarizes the effect of epinephrine administration on milk production and plasma hormones. The epinephrine and nor-epinephrine hormone are released during stress and may have adverse effect on milk yield of lactating animals. Lactating cows were administered epinephrine intravenously (@0.5 ug/kg body wt./ day) for a period of five days. Blood samples were collected before an...

The cyanobacterial neurotoxin β-N-methylamino-L-alanine (BMAA) has been implicated in the etiology of neurodegenerative disease and proposed to be biomagnified in terrestrial and aquatic food chains. We have previously shown that the neonatal period in rats, which in humans corresponds to the last trimester of pregnancy and the first few years of age, is a particularly sensitive period for expo...

Previous investigations have shown that the lipid composition of cerebral membranes and dopaminergic neurotransmission are changed under chronic alpha-linolenic acid diet deficiency in the rat. This study investigated whether these changes could be reversed and if the stage of brain maturation might play a role in the recovery process.

Toxic milk (tx) is a copper disorder of mice that causes a hepatic accumulation of copper similar to that seen in patients with Wilson disease. Both disorders are caused by a defect in the ATP7B copper-transporting ATPase. A feature of the tx phenotype is the production of copper-deficient milk by lactating dams homozygous for the tx mutation; the milk is lethal to the pups. It has not been det...

Background: To contribute to the fight against malnutrition among women of reproductive age, this study aimed to evaluate the quality of food and the nutritional status of pregnant and lactating women. Methods: This cross-sectional study was conducted from June 2018 to September 2018 to explore the frequency and distribution of the dietary, socioeconomic, and health characteristics of pregnant ...

Abstract. Given a doubling measure μ on R, it is a classical result of harmonic analysis that Calderón-Zygmund operators which are bounded in L(μ) are also of weak type (1, 1). Recently it has been shown that the same result holds if one substitutes the doubling condition on μ by a mild growth condition on μ. In this paper another proof of this result is given. The proof is very close in spirit...
