The formulation composition identified was subsequently used for the optimization of the manufacturing parameters viz. sonication time and amplitude, using a Central Composite Design (CCD) . The LC and EE, in vitro CLA release, cytotoxicity, osmolarity, pH, degree of crystallinity and lipid modification, elemental analysis and surface morphology of the optimized batch was investigated and mon itored to ensure that CLA - loaded NLC, of the desirable quality, had been produced. On the day of manufacture the mean PS and PDI of the optimized CLA - loaded NLC formulation adjusted to physiological osmolarity (250 – 450 mOsm/kg) was 461.9 ± 40.16 nm and 0. 523 ± 0.104, respectively. The ZP for the optimized NLC generated on the day of manufacture using HPLC grade water as the dispersion medium was - 20.5 ± 4.82 mV. The pH and osmolarity of the optimized CLA - loaded NLC formulation was 7.76 ± 0.01 and 316 ± iii 2 m Osm/Kg, respectively and the EE was 88.62 ± 0.23 %. The optimized NLC exhibited a decreased crystallinity in comparison to the bulk lipid materials. DSC, WAXS and FT - IR revealed that CLA was molecularly dispersed in the nanocarriers. The optimized CLA - load ed NLC exhibited muco - adhesive properties, when tested under stationary conditions using laser doppler anemometry (LDA). The optimized formulation also exhibited sustained release of CLA over 24 hours during in vitro release testing and CLA release was bes t described using the Baker - Lonsdale model . The cumulative % CLA released over 24 hours was 56.13 ± 0.23% and mass balance analysis revealed 41.38 ± 0.02% CLA had been retained in the NLC. In vitro cytotoxicity testing revealed that the optimized CLA - NLC w ere less cytotoxic to HeLa cells when compared to CLA alone and further confirmed that the lipids and excipients used in these studies were of GRAS status . Stability studies revealed that the EE reduced over 28 days by 14.42% and 5.14% when stored at 4 °C and 22 °C , respectively. In addition, the particle size increased from the nm to μm range for samples stored at 22 °C. The findings are a good starting point but require further optimization to ensure prolongation of stability. In addition , the technology requires additional developmental studies and a powder for reconstitution for use as a single - dose considered as single dose packaging may be a solution to the compromised formulation stability observed in these studies. The CLA - NLC produced in these stu dies exhibit sound product attributes which serve as a useful foundation for the novel delivery of antibiotics to the eye. The results suggest that the optimized NLC have the potential to enhance precorneal retention and increase ocular availability of CLA , which in turn may be useful to reduce the required dose and dosing frequency when administering CLA as a reconstituted solution to treat susceptible organisms that infect ocular tissues.]]> Tue 09 Mar 2021 16:08:52 SAST ]]> Synthesis, spectroscopic and nonlinear optical properties of asymmetric A3B type phthalocyanine complexes 3.76 × 10 − 10 ( 4a ) > 3.52 × 10 − 10 ( 4c ) > 2.29 × 10 − 10 ( 3c ) > 1.68 × 10 − 10 ( 3a ) > 1.65 × 10 − 10 ( 3b ) mW - 1 . The 휷 values trend of synthesized Pc complexes show that the asymmetrical A 3 B type metal free, cobalt and zinc Pc complexes ( 4a , 4b and 4c ) have larger 휷 values as compared to the octa - substituted symmetrical metal free, cobalt and zinc Pc complexes ( 3a , 3b and 3c ) which is attributed to the low symmetry of the Pc complexes. The five - level model rate equations were used to determine the two photon absorption, excited state absorption and ground state absorption cross sections of the synthesized complexes. The z inc A 3 B type asymmetrical Pc complexes gave the largest two photon absorption and 휎 푒 / 휎 푔 ratio values. This Pc complex could be used in future work to enhance the nonlinear response further by introducing nanomaterials and converting the Pc complex to a binuclear Pc. This work also reports on the density functional theory (DFT) calculations o f dipolar/octupolar contributions in order to study the first order hyperpolarizability of the synthesized Pc complexes.]]> Tue 09 Mar 2021 15:33:53 SAST ]]> A combined modelling approach for simulating channel–wetland exchanges in large African river basins Tue 09 Jun 2020 12:03:57 SAST ]]> Chave Chemutengure Vhiri Rengoro : Husarungano Nerwendo Rwengano Dzevashona Tue 06 Apr 2021 16:23:28 SAST ]]> A critical analysis of selected clauses in selected Double Tax Agreements (DTAs) with South Africa Tue 02 Mar 2021 10:31:40 SAST ]]> "Knowing With": New Rhodes Board Navigates Collaboration, Intimacy, and Solidarity Tue 02 Jun 2020 13:10:25 SAST ]]> A comparative analysis of social media brand image of insurance companies in South Africa: a longitudinal study Thu 30 Apr 2020 16:01:43 SAST ]]> A critical analysis of social enterprise in Slovenia Thu 26 Nov 2020 11:13:04 SAST ]]> A comparison of three models used to determine water fluxes over the Albany Thicket, Eastern Cape, South Africa: Thu 25 Jun 2020 11:52:58 SAST ]]> A critical analysis of NGOs in addressing HIV and AIDS in the context of gendered inequality: The case of Makhanda, Eastern Cape, South Africa Thu 23 Apr 2020 14:59:38 SAST ]]> A comparative analysis with selected jurisdictions of structural challenges facing the South African office of the tax ombud Thu 19 Nov 2020 15:29:47 SAST ]]> A Bayesian approach to tilted-ring modelling of galaxies Thu 19 Nov 2020 15:29:24 SAST ]]> Anticholinesterase and Antioxidant Activities of Spilanthes filicaulis Whole Plant Extracts for the Management of Alzheimer’s Disease Thu 19 Mar 2020 09:21:24 SAST ]]> Exploring domestic workers’ subjectivities through stories of their personal childcare arrangements Thu 11 Mar 2021 16:37:11 SAST ]]> An exploratory case study on the barriers, challenges and benefits of sustainability reporting by small and medium enterprises (SMEs) in South Africa Thu 11 Mar 2021 16:02:11 SAST ]]> How the leaders of an Eastern Cape development agency experienced a transition from specialist roles to the leadership roles and how this shaped their leadership identity Thu 11 Mar 2021 15:27:11 SAST ]]> Constraining the role of carbonate assimilation on spinel stability in oxide ores of the Flatreef, Bushveld Complex, South Africa Thu 08 Apr 2021 16:16:30 SAST ]]> Defended subjectivity in service-learning:a psychosocial analysis of students’ talk about service-learning in psychology Thu 04 Mar 2021 17:54:13 SAST ]]> Evaluating the cyber security skills gap relating to penetration testing Thu 04 Mar 2021 17:19:13 SAST ]]> Infant health: a community-based assessment and educational intervention in two rural communities in the Eastern Cape.

Saving Babies further reported that 22.9% of all live births in South Africa was premature and 22.8% of birthswere unexplained intra-uterine deaths. Prematurity is one major complication of chorioamnionitis. When susceptibility for chorioamnionitis is considered during early pregnancy, it is possible to intervene and prevent or even reduce the incidences and complications of chorioamnionitis.A qualitative research study was conducted in three phases. In Phase One(Part One), a theoretically constructed patient scenario of chorioamnionitis was presented to ten midwives,and semi-structured individual interviews were done to elicit information regarding how they screen for and manage chorioamnionitis. In Phase One(Part Two), experienced medical practitioners in the field of obstetrics and gynaecology were individually interviewed, also using semi-structured individual interviewsto gain their views regarding chorioamnionitis as a contributing factor to maternal morbidity and mortality. Qualitative findings in Phase Oneindicated that there is a general lack of knowledge regarding chorioamnionitis among midwives, resulting ininadequate screening, misdiagnosis and mismanagement of the condition. Experienced medical practitioners confirmed that chorioamnionitis is underdiagnosed, misdiagnosed or undiagnosed and underreported,and they hold views that it is difficult to treat and control pregnancy-related infections according to current practice.An integrative literature review was conductedin Phase Twoand literature regarding diagnostic biomarkers, screening options to diagnose chorioamnionitis and management of chorioamnionitis were extracted. After evidence synthesisofPhase Oneand Phase Twodata, a best practice guidelinefor screening and managing viiwomen withchorioamnionitiswas developed usingthe National Institute for Health and Clinical Excellence guideline development approach in Phase Three. The purpose of the best practice guideline for screening and managing women with chorioamnionitis was to provide a guideline onhow to manage women who are at risk and those who present with signs and symptoms of chorioamnionitis at any stage during their pregnancy. Five recommendations were made that involve screening for chorioamnionitisand causative factors, biomarkers to diagnose chorioamnionitis, management of chorioamnionitis that includes pharmacological and non-pharmacological management, and health education to women.Ethics for this research study were guided by the ethical principles and guidelines of the Belmont Report. The trustworthiness of this research study was adopted from Ravitch and Carl,and was based on criticality, reflexivity, collaboration, and rigour. An independent coder and reviewer wereto verify the data that were included in the best practice guideline.
