Correction of Toe-Walking Gait in Children with Spastic Cerebral Palsy by using Electrical Stimulation Therapy.

Toe-walking is a very common gait abnormality seen in children with Cerebral Palsy (CP). The present study aims to improvise the toe-walking gait by applying Electrical Stimulation (ES) therapy of the Tricep Surae (TS) muscles. The study was carried out on sixteen children with spastic CP with unilateral toe-walking gait problem, divided into the intervention group that received both ES therapy along with conventional physiotherapy treatment and the control group that received only conventional physiotherapy treatment. Both groups were treated for 60 (30 + 30) minutes per day, for 5 days a week, up to 12 weeks. The gait data were analyzed for spatiotemporal and parameters influencing the walking capacity. The results showed that those children who received the intervention had a significant increase in gait speed by 17.67 % (p = 0.019) and decrease in stride length by 10.25 % (p = 0.037), resulting in improvement of body balance. There was a significant percentage increase in initial contact (heel strike) of 85.71 % (p = 0.000) and flat foot position (loading response) of 49.2 % (p = 0.005), confirming reduction in toe-walking. There was also an increase in the swing power by 39.8 % (p = 0.028) and ground impact by 19.5 % (p = 0.003) suggesting a change in foot contact pattern. The results indicate that ES therapy on TS muscle along with conventional physiotherapy may correct the toe-walking gait in children with spastic hemiplegic CP.

Therapeutic effects of functional electrical stimulation on motor cortex in children with spastic Cerebral Palsy.

In the present study we have evaluated the electroencephalogram (EEG) signal recorded during ankle dorsal and plantar flexion in children with spastic Cerebral Palsy (CP) after Functional Electrical Stimulation (FES) of the Tibialis Anterior (TA) muscles. The intervention group had 10 children with spastic diaplegic/hemiplegic CP within the age group of 5 to 14 years of age who received both FES for 30 minutes and the conventional physiotherapy for 30 minutes a day, while the control group had 5 children who received only conventional physiotherapy for 60(30 + 30) minutes a day only. Both group were treated for 5 days a week, up to 12 weeks. The EEG data were analyzed for Peak Alpha Frequency (PAF), sensorimotor rhythm (SMR), mu wave suppression and power spectral density (PSD) of all the bands. The results showed a decrease in SMR and mu wave suppression in the intervention group as compared to the control group, indicating a positive/greater improvement in performance of motor activities. Therefore, from this study we could conclude that FES combined with conventional physiotherapy improves the motor activity in children with spastic CP.

Actividad Antimicrobianade Cuminum cyminum L / Antimicrobial Activity of Cuminum cyminum L

El comino (Cuminum cyminum) es un ingrediente habitual en la comida india. Ha sido usado desde hace mucho tiempo en la medicina tradicional para curar la diarrea, dispepsia y trastornos gástricos, así como agente antiséptico. Estudios realizados en nuestro laboratorio han mostrado que el comino tiene una potente actividad antimicrobiana sobre diversas especies de bacterias y hongos, tanto patógenas como no patógenas. Los estudios químicos realizados indican que la mayor parte de esta actividad antimicrobiana es debida al cuminaldehido [p-isopropil benzaldehido] presente en el fruto desecado de esta planta. Los estudios de concentración mínima inhibitoria (CMI) con el cuminaldehido aislado (comparado con el cuminaldehido patrón) indican que es efectivo sobre diferentes microorganismos, incluyendo cepas de bacterias, levaduras y hongos (AU)

DNA sequencing of a mouse liver protein that binds selenium: implications for selenium's mechanism of action in cancer prevention.

Complementary DNA clones for liver protein 56K (SLP-56) were isolated by screening a lambda Zap mouse liver library. The cloned cDNAs represented the complete message. The correct reading frame was verified by alignment of the deduced amino acid sequence with that of peptides sequenced from the purified protein. The primary sequence has not been reported previously since homologous DNA sequences were not found in GenBank. Most importantly, the DNA sequence did not contain an in-frame TGA codon that would code for seleno-cysteine, as occurs in the prototypic selenoprotein, glutathione peroxidase. Hydropathy analysis suggested the protein was not a membrane-spanning protein. SLP-56 was previously localized as a cytosolic-soluble protein on the basis of cell fractionation experiments. The results suggest that SLP-56 is different from proteins whose synthesis and concentration are dependent upon selenium and require TGA to encode for selenocysteine. In this respect, SLP-56 appears to be similar to liver fatty acid binding protein (SLP-14) for which selenium is a ligand. Our working hypothesis is that selenium exerts its inhibitory effects on cell growth by modulating the properties of existing growth regulatory proteins. The two proteins that are readily labeled by selenium in many rodent tissues, SLP-56 and SLP-14, would fit into this category.
