Mast seeding in conifers is characterized by the spatially synchronous and temporally variable production of seed cone crops. Large mast events (known as “mast years”) can be a visually stunning ecologically important phenomenon, supporting trophic interactions survival predators well forest regeneration. Documenting patterns generally labor-intensive, requiring repeated visual counts at consis...

statement of the problem: soft tissue reactive lesions are the most common lesions of the oral cavity. although many studies have shown the interaction of mast cells with fibroblasts and their participation in fibrosis, the role of mast cells in these lesions is not well understood. purpose: the aim of this study was to evaluate the mast cells (mcs) count in oral soft-tissue reactive lesions in...

The choice of adequate methods for epidemiological purposes remains a challenging problem in Neisseria gonorrhoeae molecular monitoring. In this study, the collection of geographically unrelated gonococci (n = 103) isolated in Russian clinics was comparably tested by (i) a traditional serotyping scheme, (ii) por typing, (iii) Neisseria gonorrhoeae multiantigen sequence typing (NG-MAST), and (iv...

BACKGROUND Type I hypersensitivity is an allergic reaction characterized by the overactivity of the immune system provoked by normally harmless substances. Glucocorticoids, anti-histamines, or mast cell stabilizers are the choices of treatment for type I hypersensitivity. Even though these drugs have the anti-allergic effect, they can have several side effects in prolong use. Cedrol is the main...

BACKGROUND The D-mannose binding lectin ArtinM is known to recruit neutrophils, to degranulate mast cells and may have potential therapeutic applications. However, the effect of ArtinM on mast cell recruitment has not been investigated. METHODOLOGY Male Wistar rats were injected i.p. with ArtinM or ConA (control). The ability of the lectin to degranulate peritoneal and mesenteric mast cells w...

Bezaisen, a Japanese typical wooden vessel of Edo era, is characterized by its single large sail supported one set huge mast. On the installation procedure mast, some references are available such as record prepared Armand Paris who was lieutenant French navy visiting Japan in early Meiji era. But those did not cover detail to get overall picture. In this paper, studied based on calculations co...

BALB/c mice received saline (SAL groups) or ovalbumin (OVA groups) intraperitoneally (days 1, 3, 5, 7, 9, 11 and 13). After 27 days, a burst of intratracheal OVA or SAL (days 40, 43 and 46) was performed. Animals were then divided into four groups (N=8, each) and intranasally instilled with saline (SAL-SAL and OVA-SAL) or residual oil fly ash (SAL-ROFA and OVA-ROFA). 24h later, total, initial a...

Introduction: The cornerstone for the prognosis of canine cutaneous mast cell tumor has been the histological grade. A critical appraisal of the available literature can help pathologists and clinicians better understand the values and limitations of histological grading. The first consensus document of the OPWG on the histological grading of cutaneous mast cell tumors was divulgated in 2013. S...

This report describes an ocular mast cell tumor in a 13-year-old female sport horse. Clinical examination revealed a solitary firm mass located in the ocular mucosa, protruding from behind the left lower eyelid. The lesion was surgically removed and submitted to histopathology. Microscopically, the mass was composed of sheets of well-differentiated neoplastic round cells circumscribed by delica...

Mast cells are bone marrow derived hemopoietic (Kitamura, et al. [1-3]). The mast cell is one of the important in immune system. It from multipotent hematopoietic progenitor cells. produces a number cytokines to augment responses, growth, and differentiation other
