Norovirus is commonly associated with food and waterborne outbreaks. Genetic susceptibility to norovirus is largely dependent on presence of histo-blood group antigens HBGA , specifically ABO, secretor, and Lewis phenotypes. The aim of the study was to determine the association between HBGAs to norovirus susceptibility during a large norovirus foodborne outbreak linked to genotype GII.

Non-secretor status; a predisposing factor for vaginal candidiasis.

Secretor status refers to the presence or absence of water-soluble ABO blood group antigens in a person's bodily fluids , such as saliva , tears , breast milk , urine , and semen. People who secrete these antigens in their bodily fluids are referred to as secretors , while people who do not are termed non-secretors. Secretor status is controlled by the FUT2 gene also called the Se gene , and the secretor phenotype is always inherited in an autosomal dominant manner, being expressed by individuals who have at least one functioning copy of the gene. The non-secretor phenotype se is a recessive trait. Non-secretors have reduced susceptibility to the most common strains of norovirus. All of these genes encode glycosyltransferases , which are enzymes that add sugars to precursor substances to create new substances. The H antigen is required for ABO blood group antigens to be formed.

Pemphigus is a chronic inflammatory and autoimmune disease which can cause blisters and mucocutaneous erosions. ABO secretor refers to those who secrete ABO blood group antigens based on their blood type in body fluids such as saliva, sweat, tears, semen, and serum. Previous studies showed that nonsecretor people are more prone to certain autoimmune diseases. The aim of this study was to determine the ABO secretor status in the saliva of patients with pemphigus vulgaris. Materials and Methods. This case-control study was conducted on 35 patients with pemphigus vulgaris and 35 healthy controls. The two groups were matched for age and gender.

Secretor status

With respect to the ABO blood types, it is very difficult to state that one type is more advantageous than another. Each blood type has its own strengths and characteristic weaknesses. However, this does not appear to be the case with the Secretor gene. As a generality, being a Non-secretor based on all of the available information does actually appear to be a potential health disadvantage. At a very basic level, being able to secrete blood type into your saliva, mucus, etc. An additional advantage of being a Secretor might be a generalized tendency to promote a stabilized, blood-type friendly intestinal bacterial ecosystem. Many of the friendly probiotic bacteria in your digestive system actually use your blood type as one of their preferential foods.

The fucosylated ABH antigens, which constitute the molecular basis for the ABO blood group system, are also expressed in salivary secretions and gastrointestinal epithelia in individuals of positive secretor status; however, the biological function of the ABO blood group system is unknown. Gastric mucosa biopsies of 41 Rhesus monkeys originating from Southern Asia were analyzed by immunohistochemistry. A majority of these animals were found to be of blood group B and weak-secretor phenotype i. A selected group of ten monkeys was inoculated with Helicobacter pylori and studied for changes in gastric mucosal glycosylation during a month period. We observed a loss in mucosal fucosylation and concurrent induction and time-dependent dynamics in gastric mucosal sialylation carbohydrate marker of inflammation , which affect H.

Venkatesh Published Biology, Medicine Indian journal of physiology and pharmacology. A secretor is an individual who secretes blood group antigens into body fluids such as saliva, sweat, tears, semen and serum. An attempt has been made to establish the correlation between the secretor status and susceptibility to vaginal candidiasis.

SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field.


Соши показала на экран. Все сгрудились вокруг нее и прочитали текст: …распространено заблуждение, будто на Нагасаки была сброшена плутониевая бомба. На самом деле в ней использовался уран, как и в ее сестрице, сброшенной на Хиросиму. - Но… - Сьюзан еле обрела дар речи.  - Если оба элемента - уран, то как мы найдем различие между. - А вдруг Танкадо ошибся? - вмешался Фонтейн.

 - Это ведь хорошо, правда. - Нет! - взорвался Джабба.  - Это плохо. Это очень и очень плохо. - Спокойствие, - потребовал Фонтейн.  - На какие же параметры нацелен этот червь.

Пришла пора действовать. Нужно выключить ТРАНСТЕКСТ и бежать. Она посмотрела на светящиеся мониторы Стратмора, бросилась к его письменному столу и начала нажимать на клавиши. Отключить ТРАНСТЕКСТТеперь это нетрудная задача, поскольку она находится возле командного терминала. Она вызвала нужное командное окно и напечатала: ВЫКЛЮЧИТЬ КОМПЬЮТЕР Палец привычно потянулся к клавише Ввод. - Сьюзан! - рявкнул голос у нее за спиной.

Мозговой штурм был своего рода разведывательным экспериментом, который его создатели называли Симулятором причин и следствий. Сначала он предназначался для использования в ходе избирательных кампаний как способ создания в режиме реального времени моделей данной политической среды. Загруженная громадным количеством информации программа создавала паутину относительных величин - гипотетическую модель взаимодействия политических переменных, включая известных политиков, их штабы, личные взаимоотношения, острые проблемы, мотивации, отягощенные такими факторами, как секс, этническая принадлежность, деньги и власть.

Отпусти меня! - Он попробовал приподняться, но не смог даже повернуться. В перерывах между сигналами Сьюзан выкрикнула: - Ты - Северная Дакота, Энсей Танкадо передал тебе копию ключа. Он нужен мне немедленно.
