A note on the Banach space of preregular maps
No full textThe aim of this paper is to give simple proofs for Jeurnink's characterizations of preregular maps in terms of Θ-maps acting between Banach lattices. For Banach lattices E and F, we achieve our goal by considering the space Lβ(E, F) of all those linear maps T: E → F for which there exists a constant K such that {double pipe}Vn i=1 {pipe}Txi{pipe} ≤ K {double pipe}Vn i=1{pipe}xi for all finite sequences x1, ..., xn e{open}E. We show that, if Lβ(E; F), and the spaces L Θ (E; F) of Θ -map and Lpr(E; F) of preregular maps are respectively endowed with their canonical norms, then they are identical Banach space
Prescribing infant formula to allergic babies

However, many infants receive formula milk for a number of reasons. Various types of formula are indicated to prevent or treat allergy and food intolerance.https://safpj.co.za/index.php/safpj/article/view/3467/0Publisher's versio
Understanding lactose intolerance and the dietary management thereof

South African Family Practice, 54(6):496-498.The original publication is available at http://www.safpj.co.zaDiets that exclude dairy may decrease gastrointestinal symptoms in symptomatic individuals who have lactose malabsorption or lactose intolerance. However, most lactose-intolerant adults can consume some lactose without experiencing major symptoms, thereby reducing the need for strict elimination of dairy products from the diet.http://www.safpj.co.za/index.php/safpj/article/view/2932Publisher's versio
The basics of prescribing infant formulas
No full textCITATION: Owens, C. J. W., Labuschagne, I. L. & Lombard, M. J. 2012. The basics of prescribing infant formulas. South African Family Practice, 54(1):25-30.The original publication is available at http://www.safpj.co.zaAll infant formulas must support the normal growth and development of infants, and this needs to be scientifically demonstrated. Formulas have to contain sufficient amounts of basic nutrients, and so are nutritionally interchangeable, with no evidence indicating that one brand is superior to another.http://www.safpj.co.za/index.php/safpj/article/view/2235Publisher's versio
Infant formula for gastro-oesophageal reflux disease
No full textCITATION: Owens, C. J. W., Labuschagne, I. L. & Lombard, M. J. 2012. Infant formula for gastro-oesophageal reflux disease. South African Family Practice, 54(2):106-110.The original publication is available at http://www.safpj.co.zaThickened infant formula is widely used as a first-line treatment for gastro-oesophageal reflux (GOR) in infants. The use thereof remains controversial, and conflicting evidence exists with regards to its efficiency. The safety of anti-reflux formula has been proven, with only a few adverse effects reported, making it safe for infants with mild symptoms of reflux.http://www.safpj.co.za/index.php/safpj/article/view/2337Publisher's versio
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
An anti-inflammatory approach to the dietary management of multiple sclerosis : a condensed review
No full textCITATION: Labuschagne, I. L. & Blaauw, R. 2018. An anti-inflammatory approach to the dietary management of multiple sclerosis : a condensed review. South African Journal of Clinical Nutrition, 31(3):67-73, doi:10.1080/16070658.2018.1465652.The original publication is available at https://www.tandfonline.comPublication of this article was funded by the Stellenbosch University Open Access Fund.Multiple sclerosis (MS) is a chronic, inflammatory, neurodegenerative demyelinating disease of the central nervous system (CNS). Inflammation is increased by high-energy Western-style diets, typically high in salt, animal fat, red meat, sugar-sweetened drinks and fried food, and low in fibre, as well as lack of physical exercise. An anti-inflammatory dietary regimen, with or without administration of dietary supplements, supporting the general trend towards an amelioration of inflammatory status, should be considered.
Understanding the role of gut microbiota in health and disease can lay the foundation to treat chronic diseases by modifying the composition of gut microbiota through lifestyle choices, including dietary habits and possibly probiotic supplementation.
Evidence from experimental, epidemiologic and clinical studies supports the potential association between poor vitamin D status and the risk of developing MS, as well as an adverse disease course. Correcting vitamin D status seems plausible in patients with MShttps://www.tandfonline.com/doi/abs/10.1080/16070658.2018.1465652#.VQcjlpWJhgUPublisher's versio
THE HUNGARIAN PEAR GERMPLASM (PYRUS COMMUNIS) AS SOURCE OF GENETIC VARIABILITY FOR BREEDING PROGRAMS.
No full textThe Hungarian pear (Pyrus communis) collection consists of 423 genotypes distributed over seven gene banks in Hungary. This is one of the most extensive collections of native and cultivated pears found in eastern Europe and includes a wide range of genotypes with small size fruit (referred to as “Miniature pears”). Based on the in situ and ex situ measures taken by governmental and other institutions for fruit tree conservation in Hungary, an overview is given on some
activities regarding areas of Pyrus collection and gene banks where pears are collected and grown. Descriptions of traits of miniature pears found in Hungarian gene banks for the interest of genetic characterization and breeding are also presented
Acidified infant formula explained
No full textCITATION: Labuschagne, I., Van Niekerk, E. & Lombard, M. J. 2013. Acidified infant formula explained. South African Family Practice, 55(3):354-356.The original publication is available at http://www.safpj.co.zaThe development of effective methods to prevent acute gastroenteritis is an important goal for infant health. Exclusive breastfeeding and postponement of complementary foods until the age of six months is recommended for healthy infants. However, at times, infant formula is required. Various types are commercially available. Acidified cow’s milk formula has been found to prevent the growth of pathogenic bacteria and concurring diarrhoeal disease.http://www.safpj.co.za/index.php/safpj/article/view/3729Publisher's versio
Diet and childhood asthma : review

South African Family Practice, 58(1):S9-S11, doi:10.1080/20786190.2014.978098.The original publication is available at http://www.tandfonline.comChildhood asthma is the most common chronic inflammatory childhood disease with almost 20% children and adolescents reporting asthma symptoms in South Africa. Associations between asthma and dietary antioxidants (vitamin E, vitamin C, carotenoids, selenium, polyphenols, and fruit), polyunsaturated fatty acids (PUFA), and vitamin D have been found. Adherence to the Mediterranean diet seems protective. This condensed review briefly reports on available data of possible protective dietary patters and practices.http://www.tandfonline.com/doi/full/10.1080/20786190.2014.978098Publisher's versio
