Сенсибилизация к ингаляционным аллергенам является одним из ключевых факторов формирования респираторных аллергозов. Среди аэроаллергенов важное значение играют аллергенные компоненты домашней пыли – клещи Dermatophagoides pteronyssinus и Dermatophagoides farinae, составляющие до 90% акарофауны жилых помещений. В формировании сенсибилизации к клещам домашней пыли также предполагается роль индивидуальных источников аллергенов. Сенсибилизация к мажорным компонентам аллергена клещей домашней пыли ассоциируется с риском развития бронхиальной астмы, к минорным (Der p 10) – риском развития перекрестных реакций с тропомиозином других беспозвоночных, тропомиозином человека. Аллергены клещей домашней пыли (Der p 2 и Der f 2) могут быть ответственны за симптомы оральной клещевой анафилаксии, а также способствовать развитию сенсибилизации к бактериальным антигенам Staphylococcus aureus и Escherichia coli. В 1 части статьи изложены биология и источники клеща домашней пыли. Представлена классификация аллергенов, пути сенсибилизации и распространенность сенсибилизации к клещу домашней пыли у детей.Allergic diseases are a serious problem in modern medicine. Sensitization to inhalation allergens is one of the key factors in the formation of respiratory allergoses. Among aeroallergens, allergenic components of domestic dust play an important role – mites Dermatophagoides pteronyssinus and Dermatophagoides farinae, that make up to 90% of the acarofauna of residential premises. In the formation of sensitization to domestic dust mites, the role of individual sources of allergens is also considered. Sensitization to the major components of the domestic dust mite allergens is associated with the risk of developing bronchial asthma, to minor ones (Der p 10) – the risk of cross-reactions with tropomyosin of other invertebrates, human tropomyosin. Domestic dust mite allergens (Der p 2 and Der f 2) may be responsible for the symptoms of oral tick-born anaphylaxis as well as for the development of sensitization to bacterial antigens of Staphylococcus aureus and Escherichia coli. Part 1 of this article outlines biology and sources of the domestic dust mite. The classification of allergens, sensitization pathways and the prevalence of sensitization to domestic dust mite in children are presented

The Negative Impacts of COVID-19 Containment Measures on South African Families - Overview and Recommendations

The World Health Organization (WHO) reported various pneumonia cases (‘Coronavirus Disease 2019’ [COVID-19]) on 31 December 2019 in Wuhan City, China, which has spread to many countries, including South Africa. In response to this, the President of South Africa declared a state of national disaster on 15th March 2020, followed by introducing various COVID-19 containment measures to minimize the spread of the virus. This paper examines the negative impacts that COVID-19 containment measures may have had on the family as a unit of society and furthermore provides recommendations to mitigate the impacts of these measures. It can be concluded that COVID-19 containment measures, specifically the lockdown restrictions, would yield both short-term and long-term impacts on proper family functioning. Several families in South Africa have been impacted financially due to the closure of business which led to the temporary/ permanent unemployment of some breadwinners in the families. This also has had a cascading impact on the food security of families and their ability to afford other basic necessities. Distress as a result of financial challenges or failure to provide for the family alongside spending much time locked down together as a family has also led to violence in the family. This was further exacerbated by the fact that the victims were stuck with the abusers and some could not report or find help due to the restricted movements. Furthermore, since most institutions predominantly moved learning online, results indicated that the lockdown restrictions affected the ability of some individuals especially those from poor families to access formal education during the period due to the lack of digital devices and internet facilities. In order to mitigate the impacts of the COVID-19 containment measures on the family, there is a need for collaborative efforts at intrapersonal, interpersonal, institutional, community and policy levels using the ecological framework

BioImageXD: an open, general-purpose and high-throughput image-processing platform.

BioImageXD puts open-source computer science tools for three-dimensional visualization and analysis into the hands of all researchers, through a user-friendly graphical interface tuned to the needs of biologists. BioImageXD has no restrictive licenses or undisclosed algorithms and enables publication of precise, reproducible and modifiable workflows. It allows simple construction of processing pipelines and should enable biologists to perform challenging analyses of complex processes. We demonstrate its performance in a study of integrin clustering in response to selected inhibitors
