Calculation of the ovule number in the genus : A method for taxa differentiation.

Premise: Recent investigations have demonstrated that the number of ovules present in the ovaries of the willow flower ( spp., Salicaceae) can be used to confirm the identification of species and hybrids. We present the method to calculate the ovule number, along with examples demonstrating its use for both species and hybrid verification.

Comparative structural and functional studies of low molecular weight tropomyosin isoforms, the TPM3 gene products.

Tropomyosin (Tpm) is an actin-associated protein and key regulator of actin filament structure and dynamics in muscle and non-muscle cells where it participates in many vital processes. Human non-muscle cells produce many Tpm isoforms; however, little is known yet about their structural and functional properties. In the present work, we have applied various methods to investigate the properties of five low molecular weight Tpm isoforms (Tpm3.

Structural and Functional Peculiarities of Cytoplasmic Tropomyosin Isoforms, the Products of and Genes.

Tropomyosin (Tpm) is one of the major protein partners of actin. Tpm molecules are -helical coiled-coil protein dimers forming a continuous head-to-tail polymer along the actin filament. Human cells produce a large number of Tpm isoforms that are thought to play a significant role in determining actin cytoskeletal functions.

Impact of A134 and E218 Amino Acid Residues of Tropomyosin on Its Flexibility and Function.

Tropomyosin (Tpm) is one of the major actin-binding proteins that play a crucial role in the regulation of muscle contraction. The flexibility of the Tpm molecule is believed to be vital for its functioning, although its role and significance are under discussion. We choose two sites of the Tpm molecule that presumably have high flexibility and stabilized them with the A134L or E218L substitutions.

[Electromyography characteristics of the motor unit action potential of the lateral pterygoid muscle and bioelectrical activity of masticatory muscles during splint therapy for pain temporomandibular joint dysfunction].

The aim of the study was to investigate the motor unit action potential (MUAP) of the lateral pterygoid muscle and bioelectrical activity of masticatory muscles in temporomandibular joint (TMJ) dysfunction patients undergoing splint therapy. The study included patients aged 18-30 with TMJ pain dysfunction (clinical group). Control group enrolled 25 healthy volunteers.
