We recorded from lobster and leech neurons with two sharp electrodes filled with solutions often used with these preparations (lobster: 0.6 M K2SO4 or 2.5 M KAc; leech: 4 M KAc), with solutions approximately matching neuron cytoplasm ion concentrations, and with 6.5 M KAc (lobster, leech) and 0.6 M KAc (lobster). We measured membrane potential, input resistance, and transient and sustained depo...

The study of several Lake Baikal leech collections offered us the possibility to determine species diversity in the Chivyrkuy Gulf, the biggest one in the lake. As a result, the first information on the Chivyrkuy Hirudinea fauna (Annelida, Clitellata) has been revealed. There are two orders and four families of leeches in the Chivyrkuy Gulf: order Rhynchobdellida (families Glossiphoniidae and P...

A highly conserved ortholog of the human complex p43/endothelial monocyte-activating polypeptide II (EMAPII) was characterized in the CNS of the leech Hirudo medicinalis. As observed in mammals, the leech complex is processed to release the cytokine HmEMAPII. Taking advantages of these similarities, we have attempted to elucidate the role of EMAPII in the CNS using the leech model. Although EMA...

A bstmct-A new efficient algorithm for bounded-distance decoding of the Leech la t t ice is presented. The algori thm decodes correctly at least ulp to the guaranteed error-correction radius of the Leech lattice. The proposed decoder is based on projecting the points of the Leech lattice onto the codewords of the (6,3,4) quar te rnary code, the hezacode Ne. Project ion on the hexacode induces p...

The medicinal leech has established a long-term mutualistic association with Aeromonas veronii, a versatile bacterium which can also display free-living waterborne and fish- or human-pathogenic lifestyles. Here, we investigated the role of antibiotics in the dynamics of interaction between the leech and its gut symbiont Aeromonas. By combining biochemical and molecular approaches, we isolated a...

An increase in intracellular cyclic AMP concentration stimulates transepithelial Na(+) transport across the skin of the leech Hirudo medicinalis, but it is unclear how cytosolic cyclic AMP levels are elevated in vivo. In search of this external stimulus, we performed Ussing chamber experiments to test several peptide hormones and neurotransmitters for their effect on Na(+) transport across leec...

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...

Sir, The ingenious article by Rastogi and Chaudhari was indeed interesting. [1] Hirudo medicinalis (medical leech) has been used in ancient medicine for various ailments. In recent years, leeches have been making a remarkable re‑emergence in medical practice, especially in reconstructive microsurgery to relieve venous congestion and to improve the microrevascularization of flaps, grafts, or rep...
