Ovicidal Activity of Maternally Applied Ecdysteroids in the Large Milkweed Bug (Heteroptera: Lygaeidae)

1982

Exogenous ecdysteroids (ecdysone, 20-hydroxyecdysone and makisterone A) administered to reproducing females of Oncopelus fasciatus (Dallas) reduced egg hatch drastically. The ovicidal activity apparently stemmed from ecdysteroids—unchanged hormone or metabolites—transferred from mother into oocyte. Different stages of embryogenesis were affected. Makisterone A, the predominant ecdysteroid in normal embryos, is by far the most effective ecdysteroid.

Drainage großer Brustdrüsenabszesse unter ästhetischen und funktionellen Aspekten

1991

In 11 puerperal women, a breast abscess was treated by drainage from the inframammary fold. Eight patients wished to continue breast feeding. During the healing period, the babies were not breast fed on the operated side. In 3 patients, the skin over the abscess necrotised, resulting in a defect of 1 to 2 cm. In 2 patients, a small seroma had to be punctured after removing the drainage tube. Aesthetic results were judged by the patients as good. Resumation of suckling on the operated side revealed only 15 to 20% milk yield compared to that of the other breast. This treatment meets aesthetic and function-preserving criteria.

Effect of seasonality on physico-chemical and microbiological properties of nicastrese milk and artisanal cheese

2021

ABSTRACT Nicastrese is an indigenous Italian goat breed reared in the Calabria region under semi-extensive practices. From January to June, the milk yield of 400 multiparous Nicastrese goats was evaluated. In addition, tank milk and ripened cheese samples were subjected to physico-chemical and microbiological analyses with the aim to assess the effect of the seasonality on quality parameters. The volatile organic compounds profile of the ripened Nicastrese cheese samples was evaluated. Results showed that the seasonality had a significant effect on milk fat, lactose, urea, citric acid contents and acidity. Microbiological analysis of tank milk samples revealed variability among the differen…

Breast-Feeding from an Evolutionary Perspective.

2021

Lactation is the most critical period of mammal feeding given the compulsory dependence on milk of the offspring during a more or less extensive period following birth. This has also been the case for the human species until relatively recent times when heterologous milk processing has allowed the alternative of artificial lactation. The advantages and disadvantages of natural and artificial lactation (formula) have been widely discussed from the biological, psychological and cultural perspectives, without reaching a general agreement among the breastfeeding women themselves or among the health professionals concerned. On the subject of breastfeeding, the information available is enormous b…

How amniotic fluid shapes early odor-guided responses to colostrum and milk (and more)

2016

Revue; Among the multiple transitions that characterize mammalian development, birth certainly is the most abrupt and spectacular. It is also the most challenging for newborns when one considers their high mortality rates in any mammalian species. Although evolution has selected newborn organisms that possess the physiological and behavioral keys leading to adapt to this harsh psychobiological challenge, their capabilities cannot be considered separately from the maternal organism and the environment she creates. Mammalian females provide indeed passive (physiological) and/or active (behavioral) assistance to complement and boost their offspring’s capacities. One notable strategy of mammali…

Differentiation among dairy products by combination of fast field cycling NMR relaxometry data and chemometrics

2021

A set of commercial milk and Sicilian cheeses was analysed by a combination of fast field cycling (FFC) nuclear magnetic resonance (NMR) relaxometry and chemometrics. The NMR dispersion (NMRD) curves were successfully analysed with a mathematical model applied on Parmigiano-Reggiano (PR) cheese. Regression parameters were led back to the molecular components of cheeses (water trapped in casein micelles, proteins and fats) and milk samples (water belonging to hydration shells around dispersed colloidal particles of different sizes and bulk water). The application of chemometric analysis on relaxometric data enabled differentiating milk from cheeses and revealing differences within the two sa…

Le varianti A1 e A2 della ?-caseina non hanno un effetto significativo sul microbiota del latteThe A1 and A2 ?-casein variants have not impact on mil…

2020

Objective: Milk is composed by a complex microbiota which can be influenced by numerous factors such as the season, the diet, the type of litter, the facility. As well, the animal's genotype can affect the composition of the milk microbiota. In milk, ?-casein is characterized by a high-level of polymorphism. The aim of this study was to verify if A1 and A2 ?-casein variants could in- fluence the milk microbioma. Materials and methods: Thirty Holstein cows were genotyped for ?-casein locus and divided into three groups. In two different sea- sons, milk samples (individual and bulk tank for each experi- mental group) and mozzarella cheese were collected separately from each group. Bacterial D…

Detection of Mycobacterium tuberculosis complex in cattle by PCR on milk, lymphnode and nasal swabs.

1998

The PCR technique was applied to the diagnosis of tuberculosis in live cattle, and both skin-test-negative and skin-test-positive animals were studied. DNA was taken from various sources including specimens of lymph node aspirates, milk, and nasal swabs. After slaughter and visual inspection, tissues such as lymph nodes, lungs, and udders from tuberculin reactors were tested by the same technique. Specific oligonucleotide primers internal to the IS6110 insertion element were used to amplify a 580-bp fragment. A 182-bp fragment was obtained by designating a nested PCR from the first amplification product. This fragment was cloned and sequenced, and after being labeled it was employed in dot …

Development of an ad hoc natural whey starter culture for the production of Vastedda della valle del Belìce cheese

2013

This work was aimed to characterize the autochthonous lactic acid bacteria (LAB) of PDO Vastedda della valle del Belìce cheeses, produced in several dairy factories, for the development of an ad hoc starter culture preparation for the production of this cheese. To this purpose, winter and spring productions were analysed, in order to isolate LAB adapted to perform the fermentation at low temperatures. Plate counts showed the total microbial counts (TMC) till levels of 9 -1almost 10 CFU g and all cheese samples were dominated by coccus LAB. Not all samples were positive for the presence of enterobacteria, but when they were found their concentrations were at similar levels in both seasons. A…
