DEAR EDITOR, We visited a 75‐year‐old G7L7 rural woman with a painful vulvar lesion highly suspicious for malignancy near the introitus measuring 5 cm × 3 cm × 2 cm. The lesion was oval shaped, erythematous, and purple colored with a soft consistency and started bleeding during examination. Inguinal lymphadenopathy was absent. The patient’s past medical history was unremarkable. Biopsy was plan...

Leech infestation of the oral cavity is uncommon parasitic infestation of dogs that can cause life threatening haemorrhage and anaemia. The aim of the case report is to present unusual sublingual attachment of leech in a hunting dog that was successfully managed by using table salt.

For $g=8,12,16$ and $24$, there is a nonzero alternating $g$-multilinear form on the ${\\rm Leech}$ lattice, unique up to scalar, which invariant by orthogonal group of Leech}$. The harmonic Siegel theta series built from these forms are modular cuspforms weight $13$ for Sp}{2g}(\\mathbb{Z})$. We prove that they eigenforms, determine one their Fourier coefficients, give informations about stand...

There are trillions of microbes found throughout the human body and they exceed the number of eukaryotic cells by 10-fold. Metagenomic studies have revealed that the majority of these microbes are found within the gut, playing an important role in the host's digestion and nutrition. The complexity of the animal digestive tract, unculturable microbes, and the lack of genetic tools for most cultu...

There is growing concern that recreational shoreline angling activity may negatively impact littoral and riparian habitats independent of any direct or indirect influences of fish harvest or fishing mortality through mechanisms such as disturbance (e.g., trampling, erosion) and pollution (e.g., littering). We sampled a suite of aquatic and terrestrial variables (i.e., water quality, aquatic and...

In the present study we analyzed the behavior and interactions among leeches in the same observation tank. Colored beads were glued onto their skin so that their behavior could be followed and quantified. When two or three leeches were present in the observation tank, they searched around for a maximum of 2 h and their motion and behavior were independent from those of their conspecifics. When ...

In an attempt to classify all of the overlap-free morphisms constructively using the Latin-square morphism, we came across an interesting counterexample, the Leech square-free morphism. We generalize the combinatorial properties of the Leech square-free morphism to gain insights on a larger class of both overlap-free morphisms and square-free morphisms.
