The bacteria profiles of wounds in diabetic patients hospitalized in northern Kwazulu-Natal, South Africa
Diabetic wound infections still remain a health concern such that correct identification of bacteria is essential in monitoring the spread of the infections as well as in the administration of the correct treatment. This study therefore focuses on isolating and identifying bacteria present in diabetic wounds of hospitalized patients in northern KwaZulu-Natal and assessing their distribution.The wound specimen were collected and swabbed onto selective and differential media. The bacteria identities were presumptively ascertained through biochemical characterization (Gram-stain, catalase test, oxidase test and API) and then confirmed through 16S rDNA sequencing.A total of 42 isolates were recovered from 83% of the patients sampled from the three participating hospitals (X, Y, and Z). Gram-negative bacilli from Enterobacteriaceaewere predominant followed by Staphylococci spp and Enterococcus faecaliswith 43% polymicrobial cases from hospital Z and 29% from hospital X. Distribution of some opportunistic pathogens and nosocomially-acquired pathogens were also observed across the patients with five bacterial identities distributed among hospital X and Z. The adverse effects associated with the recovered bacteria in diabetic wounds pose a serious health concern and preventive measure should be taken.Keywords: Diabetes mellitus, wounds, bacteria, infectio
Anti-oxidant, anti-inflammatory and antiacetylcholinesterase activity of betulinic acid and 3β- acetoxybetulinic acid from Melaleuca bracteata ‘Revolution Gold’
Purpose: To evaluate the anti-oxidant, anti-inflammatory and anti-acetylcholine esterase activities of betulinic acid (BA) and 3β- acetoxybetulinic acid (BAA) from Melaleuca bracteata. ‘Revolution Gold’.Methods: Betulinic acid was isolated from the ethyl acetate extract of M. braceteata while BAA was synthesized by acetylation of BA. Structural elucidation of the compounds was achieved by spectroscopic methods. Antioxidant potential was determined using superoxide dismustase (SOD) and catalase assay kits while iron chelation activity assessed with ferrozin. Anti-inflammatory activity was determined using cotton pellet-induced granuloma rat model. Cyclooxygenase (COX) activity evaluated by COX kits; acetylcholine kit was used for anti-acetylcholinesterase (ACHE) study.Results: The compounds significantly (p < 0.05) dose-dependently inhibited ACHE and inflammatory activity. They also significantly decreased the inhibition of SOD, catalase activity but increased iron chelation activities in a dose-dependent manner. However, BAA showed higher activity than BA for all the parameters. BAA also had a greater inhibitory effect on COX-2 than on COX-1. BAA (IC50, 0.88 mg/mL) showed better iron chelation than citric acid (0.96 ± 0.04) and EDTA (1.04 ± 0.03), the positive control.Conclusion: BA and BAA possess anti-ACHE, anti-inflammatory, antioxidant and anti-COX activities. Structural modification of BAA influences its biological activities. Therefore, BAA can potentially serve as a scaffold in synthesizing potent neurodegeneration drugs.Keywords: Betulinic acid, 3β-Acetoxybetulinic acid, Antioxidant, Anti-inflammatory, Antiacetylcholinesterase, Melaleuca bracteata. ‘Revolution Gold
False Beliefs About Diabetes Mellitus in the Kurdistan Region of Iraq: A Population-Based Study
Background. Diabetes mellitus (DM) is a chronic, non-transmissible health condition distinguished by high blood glucose levels caused by faulty insulin secretion and impaired insulin activity. People play an essential role in preventing and managing their illnesses. Thus, the misconceptions may negatively influence the prevention and management of DM.
The aim of this study was to gauge the extent of knowledge among the general population concerning DM, to determine the prevalence of misconceptions about DM in the community, and to find the factors influencing them.
Methods. A population-based study was conducted in Duhok Province, the Kurdistan Region of Iraq. A total of 2,305 adults were enrolled in the study. The study data were collected by face-to-face interview. The survey questionnaire comprised two sections: the first section included basic demographic characteristics of participants, while the second section consisted of ten questions to identify common misconceptions about DM among participants.
Results. Among the participants, there were 1,406 (61.0%) females. Participants’ age ranged from 18 to 90 years (the mean age: 54 ± 13.69 years). The most common misconceptions positively responded to were “Will I become addicted to insulin if I start taking it?”, followed by“ Does DM occur because of increased sugar intake?”. Male gender was associated with higher level of misconceptions. In addition, the misconceptions were more prevalent among diabetics as they might seek treatment from non-professionals. There was a significant association between education status and the prevalence of misconceptions. Healthcare workers were found to have a better knowledge about DM compared to the general population. Surprisingly, certain myths were prevalent even among healthcare workers.
Conclusions. Certain myths and misconceptions have been pervasive in our society. Actions must be taken to dispel these misconceptions as they lead to an avoidable burden of disease. Therefore, people’s knowledge of DM needs to be enhanced through educational programs, social media, television, newspapers and campaigns
Antithrombotic, anticoagulant and antiplatelet activity of betulinic acid and 3β-acetoxybetulinic acid from Melaleuca bracteata ‘Revolution Gold’ (Myrtaceae) Muell leaf
Purpose: To investigate the antithrombotic, anticoagulant and antiplatelet activity of betulinic acid (BA) and 3β-acetoxybetulinic acid (BAA) from Melaleuca bracteata ‘Revolution Gold’.Methods: Betulinic acid was isolated from the ethyl acetate extract of M. bracteata leaves by column chromatography, from which BAA was subsequently synthesized by acetylation. Structural elucidation of the compounds was conducted using mass spectrometry (MS), infra-red (IR) spectroscopy and nuclear magnetic resonance (NMR). The antithrombotic potential of the compounds was assessed using chromogenic substrate. Anticoagulation studies were carried using bleeding tail time assay in a rat model. Plasma-rich platelets from rats were employed for platelet aggregation studies using light microscope.Results: The compounds significantly (p < 0.05) showed antithrombotic activities in a dose-dependent manner. BAA showed significantly (p < 0.05) higher half-maximal concentration (IC50) value of 1.10 ± 0.03 mg/mL than BA (2.36 ± 0.09 mg/mL) and aspirin (2.65 ± 0.01 mg/mL) which served as positive control. The compounds exhibited anticoagulation activity with poor bleeding time, compared to aspirin. Likewise, the compounds attenuated platelets aggregation induced by thrombin.Conclusion: BAA displays better antithrombotic, antiplatelet, and anticoagulant activities than BA. Therefore, it may be a promising remedy for the management of cardiovascular events.Keywords: Betulinic acid, Thrombin, Anticoagulation, Antiplatelet, Aspirin, Platelet
Comparative Analyses And Structural Insights Of The Novel Cytochrome P450 Fusion Protein Family CYP5619 In Oomycetes
Published ArticlePhylogenetic and structural analysis of P450 proteins fused to peroxidase/dioxygenase has not
been reported yet. We present phylogenetic and in silico structural analysis of the novel P450 fusion
family CYP5619 from the deadliest fish pathogenic oomycete, Saprolegnia diclina. Data-mining and
annotation of CYP5619 members revealed their unique presence in oomycetes. CYP5619 members
have the highest number of conserved amino acids among eukaryotic P450s. The highest number
of conserved amino acids (78%) occurred in the peroxidase/dioxygenase domain compared to the
P450 domain (22%). In silico structural analysis using a high-quality CYP5619A1 model revealed
that CYP5619A1 has characteristic P450 structural motifs including EXXR and CXG. However, the
heme-binding domain (CXG) in CYP5619 members was found to be highly degenerated. The in silico
substrate binding pattern revealed that CYP5619A1 have a high affinity to medium chain fatty acids.
Interestingly, the controlling agent of S. diclina malachite green was predicted to have the highest
binding affinity, along with linoleic acid. However, unlike fatty acids, none of the active site amino
acids formed hydrogen bonds with malachite green. The study’s results will pave the way for assessing
CYP5619A1’s role in S. diclina physiology, including the nature of malachite green binding
Patients with Chronic Kidney Disease and Their Quality of Life
This study aimed at exploring the assessment of Quality of Life (QOL) in patients with Chronic Kidney Disease (CKD), and aiming at assessing the QOL of patients with stages 1–5 Chronic Kidney Disease CKD on conservative treatment in order to identify a possible association between Quality Of Life QOL and progression of kidney insufficiency. The results were compared with those obtained for patients on hemodialysis. Sociodemographic, clinical and laboratory data were also evaluated. And the study concluded that research efforts have expanded significantly to determine the state of pediatric CKD patient HRQOL and the factors that impact HRQOL across all stages of CKD and all modalities of renal replacement therapy. Data from all studies suggest that children with a renal transplant fare better with respect to HRQOL than those receiving dialysis.
In vitro and in vivo antioxidant potentials of the methanolic crude extract from Inula glomerata Oliv. & Hiern (Asteraceae) and Salacia kraussii (Harv.) Harv (Celastraceae)
Reactive oxygen species are implicated in multiple pathological conditions including erectile
dysfunction. This study evaluated the in vitro and in vivo antioxidant potential of the methanolic extracts
of Inula glomerata and Salacia kraussii. The plant materials were pulverized and extracted with
methanol. The phytochemical analysis, ability of the crude extracts to scavenge free radicals (ABTS,
DPPH, NO.) in vitro as well as the total phenolic and flavonoid contents was investigated. In vivo,
antioxidant potentials of the crude extracts (50/250 mg/kg body weight) were determined in an erectile
dysfunction rat model. The phytochemical analysis revealed that both plants contain flavonoids, tannins,
terpenoids, and alkaloids. The crude extracts at varying degree of efficiency, scavenged ABTS and DPPH
radicals. The crude extracts at low concentrations (50 mg/kg b.w) significantly (p<0.05) diminished the
level of malondialdehyde, augmented catalase activities and elevated glutathione levels. However, SOD
activities were significantly boosted in a dose-dependent manner by the crude extracts. Therefore, I.
glomerata and S. kraussii possess antioxidant properties, hence, can serve as a therapeutic modality in the
treatment of oxidative stress-induced erectile dysfunction.https://blacpma.ms-editions.cl/index.php/blacpmapm2021BiochemistryGeneticsMicrobiology and Plant Patholog
The triterpene, methyl-3β-hydroxylanosta-9,24-dien-21-oate (RA3), attenuates high glucose-induced oxidative damage and apoptosis by improving energy metabolism
BACKGROUND: Hyperglycemia-induced cardiovascular dysfunction has been linked to oxidative stress and accelerated apoptosis in the diabetic myocardium. While there is currently no treatment for diabetic cardiomyopathy
(DCM), studies suggest that the combinational use of anti-hyperglycemic agents and triterpenes could be
effective in alleviating DCM.
HYPOTHESIS: To investigate the therapeutic effect of methyl-3β-hydroxylanosta-9,24-dien-21-oate (RA3), in the
absence or presence of the anti-diabetic drug, metformin (MET), against hyperglycemia-induced cardiac injury
using an in vitro H9c2 cell model.
METHODS: To mimic a hyperglycemic state, H9c2 cells were exposed to high glucose (HG, 33 mM) for 24 h.
Thereafter, the cells were treated with RA3 (1 μM), MET (1 μM) and the combination of MET (1 μM) plus RA3 (1
μM) for 24 h, to assess the treatments therapeutic effect.
RESULTS: Biochemical analysis revealed that RA3, with or without MET, improves glucose uptake via insulindependent (IRS-1/PI3K/Akt signaling) and independent (AMPK) pathways whilst ameliorating the activity of
antioxidant enzymes in the H9c2 cells. Mechanistically, RA3 was able to alleviate HG-stimulated oxidative stress
through the inhibition of reactive oxygen species (ROS) and lipid peroxidation as well as the reduced expression
of the PKC/NF-кB cascade through decreased intracellular lipid content. Subsequently, RA3 was able to mitigate
HG-induced apoptosis by decreasing the activity of caspase 3/7 and DNA fragmentation in the cardiomyoblasts.
CONCLUSION: RA3, in the absence or presence of MET, demonstrated potent therapeutic properties against
hyperglycemia-mediated cardiac damage and could be a suitable candidate in the prevention of DCM.South African National Treasury and National Research Foundation.https://www.elsevier.com/locate/phymedpm2022BiochemistryGeneticsMicrobiology and Plant Patholog
