Wall and Shortland (1991) have shown that afferent fibers entering the cord in thoracic and lumbar roots of adult rats have branches that may penetrate up to 11 segments caudally from the root entry zone. We have investigated the extent of branching and conduction velocities of ascending and descending branches of lumbar and thoracic primary afferents in isolated spinal cords of adult hamsters ...

The process of ecotoxicant transfer through membrane was studied on the example of the pesticide lontrel (3,6-DCPA). 3,6-DCPA is able to penetrate through the model liposomal membrane. The mathematical model of mass-transfer process was established. It was found that the transfer rate of 3,6DCPA through lipid membrane equals (5-8)⋅10 M/s for all 3,6-DCPA concentrations.

Activations of mitochondrial calpains cause apoptosis-inducing factor-dependent apoptosis of retinal photoreceptor cells in the Royal College of Surgeons (RCS) rat, an animal model of retinitis pigmentosa. In the present study, we attempted to develop specific inhibitors of mitochondrial calpains that would prevent the retinal degeneration. We examined the inhibitory potency of 20-mer peptides ...

When virus and microfilariae are ingested concurrently by a mosquito, microfilariae (mf) may penetrate the mosquito midgut and introduce virus directly into the mosquito hemocoel, allowing mosquitoes to become infectious much sooner than normal and enhancing transmission of viruses by mosquitoes. Mansonella ozzardi (Manson) is a benign filarial nematode parasite of humans in Latin America and i...

Objective. Some viral infections can have a harmful effect on the functioning of nervous system and even cause serious neurological damage. This work aims to review results studies published so far concerning complications in people infected with coronaviruses, especially SARS-CoV-2, possible mechanisms responsible for Literature review. Recently, there been reports that including SARS-CoV-2 (s...

We present accurate physical parameters of the eccentric binary system V990 Her which has an orbital period P=8.193315±0.000003 days using its photometric and spectroscopic data. The components were derived as Teff1=8000±200 K, Teff2=7570±200 M1=2.01±0.07 Mʘ, M2=1.83±0.03 R1=2.22±0.02 Rʘ, R2=2.12±0.01 log(L1/Lʘ)=1.25±0.04, log(L2/Lʘ)=1.12±0.05. Our findings revealed that both are slightly evolv...
