Mouse Lab Behaviour: How to Listen to Their Preference During Maintenance in House Facilities: OAJBS Publishers

Mouse Lab Behaviour: How to Listen to Their Preference During Maintenance in House Facilities by Gabriel Oliveira in Open Access Journal of Biomedical Science

Mouse phylogeny, evolution and natural behaviour enable a new methodology for testing inputs, materials and equipment that are adequate/comfortable for the animals during their maintenance in house facilities. We developed an ICS prototype, capable of comparing two types of objects/materials based on “listening” the animal. The efficiency of the ICS can be demonstrated through the evaluation of basic materials in house facilities, such as chow, water decontamination process, floor/bed type and environmental enrichment objects. Our results demonstrate that while infant and young mice prefer commercial unprocessed chow over autoclaved one, adult mice show no preferences. Regarding water consume, at any age (4, 6 and 8 weeks of life - wko), differences in the water decontamination process - filtered or autoclaved – were observed. However, in relation to the floor/bed, at all ages, wood shavings were preferred (90%) over pine flakes. Finally, the environmental enrichment categories preferred are those that offer shelter and nesting possibility. Our results showed that ICS uses adequate evaluation parameters, allowing the handler to “hear” the mouse’s preference, and through screening tests insert material/object(s) in its routine that significantly minimize distress and suffering.

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: OAJBS Publishers

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: OAJBS Publishers

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/
