Effect of Cognitive Load on Postural Stability by Kristyna Rusnakova in Open Access Journal of Biomedical Science 

Postural stability is the dynamics of the postural control system associated with maintaining balance during quiet standing. Postural control during normal upright stance in humans is a well-learned task. The control of posture is affected by physiological factors such as the muscular and the skeletal system, fatigue, or psychological factors such as the anxiety arousal, state of mind, attention and cognitive load. This study investigates the effects of cognitive load on postural stability in airborne units of czech army. Postural sway using static posturography was assessed in 18 pilots before and after cognitive load. Postural stability was quantified using force plate measures of center of pressure (COP) and center of gravity (COG), cognitive load was assessed by selected tests for spatial abilities while obstructing listening loud sound (crying baby). Each standing trial was performed with eyes open and eyes close for 60 s. Results showed that cognitive load led to less body sway, while individuals had a smaller ellipse area of center of gravity after cognitive load compared with a default situation. In conclusion, control of body sway and cognitive functioning are to some extent related, cognitive load can arouse concentration and can affect postural stability

Facile Synthesis of Chitosan Nanoparticle with Different Features and Histopathological Ultrastructural Study on The Effect of Its Bio-complex with Bovine Serum Albumin in Mice Liver by Maged El-Kemary* in Open Access Journal of Biomedical Science (OAJBS)   We have synthesized chitosan nanoparticles (CS-NPs) with different characteristics using ionic gelation method. Results showed that the synthesized CS-NPs with different concentrations of trisodium polyphosphate (TPP) are irregular – spherical shaped with narrow size distribution and high stability. The microporous chitosan was also synthesized with new features characterized with different techniques as SEM, EDX, FTIR and BET. The synthesized microporous chitosan has a surface area and pore volume of 245.571m 2 /g and 0.155cm 3 /g respectively. Its microporous surface is functionalized with carboxyl and amine groups. Histopathological and ultrastructural studies of mice liver were performed using optical and scanning electron m...

Review on Analysis of Breast Tumor with Methods of Treatment by Nagham Mahmood Aljamali* in Open Access Journal of Biomedical Science (OAJBS) Breast malignance is the greatest public in ladies, with a high incidence in North America and Eastern Europe, medium in Southern Europe and the Middle East and low in the Far East. Breast malignance is the second most common malignance in the world after lung malignance, and since it happens a lot, the doctors asked the women to examine themselves by themselves, in order to discover the signs of the disease early before it spreads. It is possible that this disease can be treated after being diagnosed by a specialized doctor and determining the type of tumor in the breast, and the surgeon removes the breast completely and starts chemotherapy about 6 doses, then radiotherapy, how many sessions will be determined by the doctor, and then hormonal therapy, a medicine called Tamoxafin or any medicine determined by the doctor, and it is possible. This ...

Assessment of Medication Errors in Emergency Ward at Nekemte Referral Hospital, West Ethiopia by Balisa Mosisa* in Open Access Journal of Biomedical Science (OAJBS) Medication error is defined as failure in the treatment process that leads to or has the potential to lead to harm to the patient. It may occur at each five stages of drug ordering and delivery including prescription, transcription, dispensing, and administration or monitoring. Prevalence of medication error in healthcare settings have been found that they were common in hospitals. A significant proportion of medication errors are associated with actual or potentially harmful effects. https://biomedscis.com/fulltext/assessment-of-medication-errors-in-emergency-ward-at-nekemte-referral-hospital-west-ethiopia.ID.000398.php To Know More About Open Access Journal of Biomedical Science Please Visit: Biomedscis Are Click on:   https://Biomedscis.Com/
