Reforming the Approach to Alternative Dispute Resolution in Kenyan Industrial Disputes: A Comparative Analysis

Dispute resolution plays an important role in industrial relations. This is because conflicts are an inherent part in any relationship and industrial relationships are not exempt from this. To this end it is important to have a dispute resolution system that ensures efficient and effective resolution of disputes that arise in the course of industrial relationships. Efficient and effective dispute resolution is particularly important in the industrial relations arena as industrial relations attract various stakeholders, some who may not necessarily be a part of the dispute that arises, but who might inadvertently be affected in the situation of an unresolved dispute. Traditionally litigation has been the most commonly utilized medium of resolution of industrial disputes, with disputants rather choosing to take the dispute to the courts of law for adjudication and determination. However with the advent of alternative means of dispute resolution such as negotiation, mediation and arbitration, it has become paramount that these alternative dispute resolution methods be promoted for the reasons of expediency and efficiency. Regardless of the advent of such methods of dispute resolution, courts have still exercised some form of control and oversight of the dispute processes, and such oversight can be easily misused to defeat the main intention of having the alternative dispute resolution processes in the first place. This thesis discusses reforming the approach to alternative dispute resolution in Kenyan industrial disputes, so as to achieve maximum efficiency of the system. In doing this, the thesis does a comparative analysis of the systems of South Africa and Australia respectively

Vaginal Histological Changes Of The Baboon During The Normal Menstrual Cycle And Pregnancy

Background: A baboon, a non-human primate, is phylogenetically close to human and has been used to study in detail aspects of reproductive physiology that cannot be studied in humans for ethical reasons.Objective: To determine the histological changes in baboon vagina associated with cyclic variations during normal menstrual cycle.Setting: The experiments were carried out at Institute of Primate Research (IPR), Karen, Nairobi, Kenya.Subjects: Nine adult healthy female olive baboons were used in this study. These baboons were monitored over a period of one year and found to have regular menstrual cycles. The vaginal biopsies were taken at different menstrual stages, fixed in 10% formalin and processed to evaluate histological changes.Results: Observation of the histological sections of the biopsies by light microscopy showed that there were histological changes associated with cyclic variations in female olive baboon. During the luteal phase, menstrual phase and pregnancy the squamous epithelium was very thin. The layer gradually thickens throughout the proliferative phase and was thickest during the ovulation period.Conclusion: The changes in squamous epithelium suggest that the baboon vagina undergoes histological changes throughout the menstrual cycle which may be associated with hormonal variations. The data from this study also suggest that olive baboon is a good model for investigating possible effects of hormonal contraceptives on vaginal epithelium and the mechanism of female heterosexual transmission of HIV

Bioprospecting Staphylococcus Phages with Therapeutic and Bio-Control Potential

Emergence of antibiotic-resistant bacteria is a serious threat to the public health. This is also true for Staphylococcus aureus and other staphylococci. Staphylococcus phages Stab20, Stab21, Stab22, and Stab23, were isolated in Albania. Based on genomic and phylogenetic analysis, they were classified to genus Kayvirus of the subfamily Twortvirinae. In this work, we describe the in-depth characterization of the phages that electron microscopy confirmed to be myoviruses. These phages showed tolerance to pH range of 5.4 to 9.4, to maximum UV radiation energy of 25 µJ/cm2, to temperatures up to 45 °C, and to ethanol concentrations up to 25%, and complete resistance to chloroform. The adsorption rate constants of the phages ranged between 1.0 × 10−9 mL/min and 4.7 × 10−9 mL/min, and the burst size was from 42 to 130 plaque-forming units. The phages Stab20, 21, 22, and 23, originally isolated using Staphylococcus xylosus as a host, demonstrated varied host ranges among different Staphylococcus strains suggesting that they could be included in cocktail formulations for therapeutic or bio-control purpose. Phage particle proteomes, consisting on average of ca 60–70 gene products, revealed, in addition to straight-forward structural proteins, also the presence of enzymes such DNA polymerase, helicases, recombinases, exonucleases, and RNA ligase polymer. They are likely to be injected into the bacteria along with the genomic DNA to take over the host metabolism as soon as possible after infection

Genomic characterization of four novel Staphylococcus myoviruses

We report here the annotation of the complete genomes of four novel lytic Staphylococcus phages; Stab20, Stab21, Stab22 and Stab23. These phages have double-stranded DNA genomes ranging between 153,338 and 155,962 bp in size with terminal repeats of 10,814–12,304 bp. The genome analysis suggests that they represent new phage species within the genus Kayvirus in the subfamily Twortvirinae of the family Herelleviridae.Peer reviewe

Prevalence and geographical distribution of Papio hamadryas papillomavirus 1 (PhPV1) in Kenyan baboons

Papio hamadryas papillomavirus (PhPV) 1, 2, and 3, are Alphapapillomaviruses that have been detected in Kenyan Olive baboons but the distribution is unknown. Therefore, cervical screening for PhPV1 was performed in baboons from various areas in Kenya using a nested polymerase chain reaction. The prevalence rate was 33%.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135993/1/jmp12247.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/135993/2/jmp12247_am.pd

DETERMINATION OF ANTIGEN LEVELS: T-PLASTIN, TRANSGELIN AND CA-125 IN BABOONS WITH INDUCED ENDOMETRIOSIS

Endometriosis is defined as the presence of endometrial-like tissue outside the uterine cavity and is associated with chronic intra-pelvic inflammation. Its symptoms, which are often severe, have a negative impact on a woman’s quality of life. They include chronic pelvic pain and infertility. It is estimated that about 10% women in their reproductive ages are affected by the disease globally. Currently, diagnostic methods are laparoscopy with histological confirmation and non-invasive such as ultrasound and the quantification of CA-125 biomarker in serum. CA-125 is known to be elevated in endometriosis, however it does not have sufficient diagnostic power as a single biomarker of endometriosis. Due to this, there is a need to determine other antigens that would act as potential biomarkers for endometriosis. It has been observed that Transgelin and T-Plastin are upregulated in endometriosis lesions and in secretory phase of endometrium respectively. There is insufficient data available showing the concentration of T-plastin in serum or plasma in the development of endometriosis. The main objective of this study was to identify whether T-plastin, Transgelin and CA-125 are potential biomarkers in early diagnosis of endometriosis using animal model for endometriosis. The baboon model represents clinically relevant research models for endometriosis. This study compared the levels of T-plastin, Transgelin and CA-125 in the peripheral blood and peritoneal fluid of baboons before and after induction of endometriosis. In this prospective, case-control study, ten female baboons (Papio anubis, 9-15 kg each) of proven fertility that have had at least one menstruation during captivity, were induced by intra-pelvic injection of menstrual endometrium on day 1 or 2 of menstruation followed by staging laparoscopy. Serum and peritoneal fluid samples were collected prior to induction to serve as controls.T-Plastin, Transgelin and CA-125 were measured using commercially available ELISA Kits. Data was analyzed using non-parametric test and level of significance at p<0.005. T-Plastin and Transgelin had insignificant p values in both peripheral blood and peritoneal fluid while CA-125 showed p=0.0003 in peripheral blood and p=0.0279 in peritoneal fluid. Diagnostic performance of individual biomarkers was determined by Receiver Operating Characteristic (ROC) with the Area under the curve (AUC) equal to 0.5 showing T-Plastin and Transgelin in both serum and peritoneal fluid unreliable for use as biomarkers in endometriosis. CA-125 levels in peritoneal fluid had an AUC of 0.7900 indicating it can be used as potential biomarkers for endometriosis.

Experimental phage therapy against haematogenous multi-drug resistant <i>Staphylococcus aureus</i> pneumonia in mice

Background: Community-acquired haematogenous Staphylococcus aureus pneumonia is a rare infection, though it can be acquired nosocomially. Currently, antibiotics used against S. aureus pneumonia have shown reduced efficacy. Thus, there is need for an alternative therapy against multidrug-resistant S. aureus (MDRSA) strains in the community. Objective: We sought to determine the efficacy of environmentally-obtained S. aureus lytic phage against haematogenous MDRSA pneumonia in mice. Methods: Phages and MDRSA were isolated from sewage samples collected within Nairobi County, Kenya. Isolated S. aureus bacteria were screened for resistance against ceftazidime, oxacillin, vancomycin, netilmicin, gentamicin, erythromycin, trimethroprim-sulfamethoxazole and cefuroxime. Thirty BALB/c mice aged six to eight weeks were randomly assigned into three groups: the MDRSA-infection group (n = 20), the phage-infection group (n = 5) and the non-infection group (n = 5). Mice were infected with either MDRSA or phage (108 CFU/mL) and treated after 72 hours with a single dose of clindamycin (8 mg/kg/bwt) or 108 PFU/mL of phage or a combination therapy (clindamycin and phage). The efficacy of phage, clindamycin or clindamycin with phage combination was determined using resolution of lung pathology and bacterial load in lung homogenates. Results: The viable MDRSA count was 0.5 ± 0.2 log10 CFU/gm in the phage-treated group,   4.4 ± 0.2 log10 CFU/gm in the clindamycin-treated group and 4.0 ± 0.2 log10 CFU/gm in the combination-treated group. The efficacy of phage therapy was significantly different from other therapeutic modes (p = 0 < 0.0001). Histology showed that the mice treated with phage did not develop pneumonia. Conclusion: Phage therapy is effective against haematogenous MDRSA infection. Thus, it can be explored as an alternative treatment method
