OBJECTIVES This study aimed towards the biosynthesis, characterisation,

METHODS Culture conditions (AgNO3 concentration, pH, and incubation

The characterisation of AgNPs and their stability were evaluated by
UV-visible spectrophotometry and scanning electron microscopy.
FINDINGS The characteristic UV-visible absorbance peak was observed in
the 420-430 nm range. Most of the particles were spherical in shape
within a size range of 33-300 nm. The biosynthesized AgNPs exhibited
higher stability than that exhibited by chemically synthesized AgNPs in
the presence of electrolytes. The biosynthesized AgNPs exhibited
antimicrobial activity against Escherichia coli, P. aeruginosa,

Methods: Seven focus-group discussions were held. Men at the end of
their university studies were purposefully selected. A topic guide was

Results: Four categories were developed through the analytic process:
fixed gender roles patriarchal values are accepted in society, female
mobility control, and slowly changing attitudes; violence not accepted

abstract = {Introduction
Disc herniation is a complex spinal disorder associated with disability
and high healthcare cost. Lumbar disc herniation is strongly associated
with disc degeneration. Candidate genes of the aggrecan metabolic
pathway may associate with the severity of lumbar disc herniation.
Objectives
This study evaluated the association of single nucleotide variants
(SNVs) of the candidate genes of the aggrecan metabolic pathway with the
severity of lumbar disc herniation in patients with chronic mechanical
low back pain. In addition, we assessed the in-silico functional
analysis of the significant SNVs and association of their haplotypes
with the severity of lumbar disc herniation.
Methods
A descriptive cross sectional study was carried out on 106 patients.
Severity of disc herniation and disc degeneration were assessed on
T2-weighted mid sagittal lumbar MRI scan. Sixty two exonic SNVs of ten
candidate genes of aggrecan metabolic pathway (ACAN, IL1A, IL1B, IL6,
MMP3, ADAMTS4, ADAMTS5, TIMP1, TIMP2 and TIMP3) were genotyped on a
Sequenom MassARRAY iPLEX platform. Multivariable linear regression
analysis was carried out using PLINK 1.9 software adjusting for age,
gender, body mass index and severity of disc degeneration. Four online
bioinformatics tools (Provean, SIFT, PolyPhen and Mutation Taster) were
used for in-silico functional analysis.

Disc herniation is a complex spinal disorder associated with disability
and high healthcare cost. Lumbar disc herniation is strongly associated
with disc degeneration. Candidate genes of the aggrecan metabolic
pathway may associate with the severity of lumbar disc herniation.
Objectives
This study evaluated the association of single nucleotide variants
(SNVs) of the candidate genes of the aggrecan metabolic pathway with the
severity of lumbar disc herniation in patients with chronic mechanical
low back pain. In addition, we assessed the in-silico functional
analysis of the significant SNVs and association of their haplotypes
with the severity of lumbar disc herniation.
Methods
A descriptive cross sectional study was carried out on 106 patients.
Severity of disc herniation and disc degeneration were assessed on
T2-weighted mid sagittal lumbar MRI scan. Sixty two exonic SNVs of ten
candidate genes of aggrecan metabolic pathway (ACAN, IL1A, IL1B, IL6,
MMP3, ADAMTS4, ADAMTS5, TIMP1, TIMP2 and TIMP3) were genotyped on a
Sequenom MassARRAY iPLEX platform. Multivariable linear regression
analysis was carried out using PLINK 1.9 software adjusting for age,
gender, body mass index and severity of disc degeneration. Four online
bioinformatics tools (Provean, SIFT, PolyPhen and Mutation Taster) were
used for in-silico functional analysis.
Results
Mean age was 52.42 +/- 9.42 years and 69.8% were females. The mean
severity of disc herniation was 2.81 +/- 1.98. The rs2272023,
rs35430524, rs2882676, rs2351491, rs938609, rs3825994, rs1042630,

severe dengue. Vascular leak typically becomes clinically evident 3-6
days after the onset of illness, which is known as the critical phase.
This critical phase follows the period of peak viraemia, and lasts for
24-48 hr and usually shows rapid and complete reversal, suggesting that
it is likely to occur as a result of inflammatory mediators, rather than
infection of the endothelium. Cytokines such as tumour necrosis factor-,
which are known to be elevated in the critical phase of dengue, are
likely to be contributing factors. Dengue NS1, a soluble viral protein,
has also been shown to disrupt the endothelial glycocalyx and thus
contribute to vascular leak, although there appears to be a discordance
between the timing of NS1 antigenaemia and occurrence of vascular leak.
In addition, many inflammatory lipid mediators are elevated in acute
dengue viral infection such as platelet activating factor (PAF) and
leukotrienes. Furthermore, many other inflammatory mediators such as
vascular endothelial growth factor and angiopoietin-2 have been shown to
be elevated in patients with dengue haemorrhagic fever, exerting their
action in part by inducing the activity of phospholipases, which have
diverse inflammatory effects including generation of PAF. Platelets have
also been shown to significantly contribute to endothelial dysfunction
by production of interleukin-1 through activation of the NLRP3
inflammasome and also by inducing production of inflammatory cytokines
