Safety and efficacy of galactogogues: substances that induce, maintain and increase breast milk production.

Abstract: Poor production of breast milk is the most frequent cause of breast lactation failure. Often, physician prescribe medications or other substances to solve this problem. The use of galactogogues should be limited to those situations in which reduced milk production from treatable causes has been excluded. One of the most frequent indication for the use of galactogogues is the diminution of milk production in mothers using indirect lactation, particularly in the case of preterm birth. The objective of this review is to analyze to the literature relating to the principal drugs used as galactogogues (metoclopramide, domperidone, chlorpromazine, sulpiride, oxytocin, growth hormone, thyrotrophin releasing hormone, medroxyprogesterone). Have been also analyzed galactogogues based on herbs and other natural substances (fenugreek, galega and milk thistle). We have evaluated their mechanism of action, transfer to maternal milk, effectiveness and potential side effects for mother and infant, suggested doses for galactogogic effect, and recommendation for breastfeeding.

Internal and External R&D: A Sample Selection Approach

Abstract: This study underlines that the decision to enter into an external R&D relationship is related to an antecedent decision to carry out R&D. This calls for an empirical approach that permits the joint analysis of the determinants of the two decisions, correcting for sample selectivity. Based on a sample of Italian manufacturing firms, the results confirm the need to adopt this approach. Another contribution made by this study is the managerial implications that can be derived from its empirical model, which provide a better understanding of the factors associated with a firm's decision to engage in R&D both independently and with external partners.

Innovation and Employment: Evidence from Italian Microdata

Abstract: The microeconomic empirical literature devoted to the link between innovation and employment tends to suggest that technological change has a positive effect on jobs, at least at the level of the firm. The main purpose of this paper is to see whether this result still holds in a situation where intermediate technologies are implemented mainly through gross innovative investments, as in Italian manufacturing. Applying GMM-SYS to an employment equation augmented for technology and using a unique longitudinal dataset of 575 Italian manufacturing firms over the period 1992-1997, this paper finds a significant - although small in size - positive relationship between innovation and employment. While the links with sales and wages have the expected signs and turn out to be significant, the job creating impact of innovation proves robust after checking for time, industry, firm's size and geographical fixed effects.

The Dual Role of Microglia in ALS: Mechanisms and Therapeutic Approaches.

Abstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by a non-cell autonomous motor neuron loss. While it is generally believed that the disease onset takes place inside motor neurons, different cell types mediating neuroinflammatory processes are considered deeply involved in the progression of the disease. On these grounds, many treatments have been tested on ALS animals with the aim of inhibiting or reducing the pro-inflammatory action of microglia and astrocytes and counteract the progression of the disease. Unfortunately, these anti-inflammatory therapies have been only modestly successful. The non-univocal role played by microglia during stress and injuries might explain this failure. Indeed, it is now well recognized that, during ALS, microglia displays different phenotypes, from surveillant in early stages, to activated states, M1 and M2, characterized by the expression of respectively harmful and protective genes in later phases of the disease. Consistently, the inhibition of microglial function seems to be a valid strategy only if the different stages of microglia polarization are taken into account, interfering with the reactivity of microglia specifically targeting only the harmful pathways and/or potentiating the trophic ones. In this review, we will analyze the features and timing of microglia activation in the light of M1/M2 phenotypes in the main mice models of ALS. Moreover, we will also revise the results obtained by different anti-inflammatory therapies aimed to unbalance the M1/M2 ratio, shifting it towards a protective outcome.

A Dietary Supplement Containing Standardized Phaseolus vulgaris Extract Influences Body Composition of Overweight Men and Women

Abstract: Background: More than one billion human adults worldwide are overweight and, therefore, are at higher risk of developing cardiovascular diseases, diabetes, and a variety of other chronic perturbations. Many believe that use of natural dietary supplements could aid in the struggle against obesity. So-called "starch blockers" are listed among natural weight loss supplements. Theoretically, they may promote weight loss by interfering with the breakdown of complex carbohydrates thereby reducing, or at least slowing, the digestive availability of carbohydrate-derived calories and/or by providing resistant starches to the lower gastrointestinal tract. Aims: The present research study examines a dietary supplement containing 445 mg of Phaseolus vulgaris extract derived from the white kidney bean, previously shown to inhibit the activity of the digestive enzyme alpha amylase, on body composition of overweight human subjects. Methods: A randomized, double-blinded, placebo-controlled study was conducted on 60 pre-selected, slightly overweight volunteers, whose weight had been essentially stable for at least six months. The volunteers were divided into two groups, homogeneous for age, gender, and body weight. The test product containing Phaseolus vulgaris extract and the placebo were taken one tablet per day for 30 consecutive days before a main meal rich in carbohydrates. Each subject's body weight, fat and non-fat mass, skin fold thickness, and waist/hip/thigh circumferences were measured. Results: After 30 days, subjects receiving Phaseolus vulgaris extract with a carbohydrate-rich, 2000- to 2200-calorie diet had significantly (p<0.001) greater reduction of body weight, BMI, fat mass, adipose tissue thickness, and waist,/hip/ thigh circumferences while maintaining lean body mass compared to subjects receiving placebo. Conclusion: The results indicate that Phaseolus vulgaris extract produces significant decrements in body weight and suggest decrements in fat mass in the face of maintained lean body mass.
