Background: Prurigo nodularis (PN) is an intensely pruritic,
inflammatory skin disease with a poorly understood pathogenesis.
Methods: We performed single-cell transcriptomic profiling of
28,695 lesional and non-lesional PN cells. Results: Lesional PN
has increased dysregulated fibroblasts (FBs) and myofibroblasts. FBs in
lesional PN were shifted towards a cancer-associated fibroblast
(CAF)-like phenotype, with POSTN+WNT5A+ CAFs increased in PN, and
similarly so in squamous cell carcinoma. A multi-center cohort study
revealed an increased risk of SCC and CAF-associated malignancies
(breast and colorectal) in PN patients. Systemic fibroproliferative
diseases (renal sclerosis and idiopathic pulmonary fibrosis) were
upregulated in PN patients. Ligand receptor analyses demonstrated a
fibroblast neuronal axis with FB-derived WNT5A and periostin
interactions with neuronal receptors MCAM and ITGAV. Compared to atopic
dermatitis and psoriasis, mesenchymal dysregulation is unique to PN with
an intermediate Th2/Th17 phenotype. Conclusion: These findings
identify a pathogenic and targetable POSTN+WNT5A+ fibroblast
subpopulation that may predispose CAF-associated malignancies in PN
patients.
Pre-transplant glomerular hyperfiltration is not a risk factor for increased renal morbidity and mortality in pediatric stem cell transplant patients

Published: August 2023

Low glomerular filtration rate (GFR) prior to stem cell transplant (SCT)
is associated with increased morbidity and mortality. The implications
of abnormally high GFRs, or glomerular hyperfiltration, prior to SCT are
unknown. Twenty two of 74 consecutive pediatric SCT patients over 2
years old at a single center were hyperfiltrating prior to SCT, median
nuclear medicine GFR 154 mL/min/1.73 m (IQR 146,
170). There was no association between any demographic and
hyperfiltration, nor between hyperfiltration and acute kidney injury (
P = 0.8), renal replacement therapy ( P = 0.63),
event-free survival ( P = 1), or chronic kidney disease (
P = 0.73).
Chest Pain Units: A Unique Healthcare Model in the World
Authors: Kumari Usha , Zahid Shanzay
Published: August 2023

Cardiovascular diseases (CVDs) are a leading cause of global mortality.
Pakistan faces a high prevalence of CVD risk factors, including
high-cholesterol diets, physical inactivity, hypertension, obesity,
diabetes, and smoking. Timely management of cardiac emergencies is
critical to saving lives. The National Institute of Cardiovascular
Diseases (NICVD) introduced an innovative cardiac care model called the
Chest Pain Unit (CPU) in May 2017. These units are strategically placed
in Karachi and other cities in Sindh to tackle traffic congestion amid
the emergency and serve densely populated areas. Since its inception,
CPUs have treated approximately 990,640 individuals and saved over
22,443 lives. CPUs specialize in pre-hospital diagnosis and management
of acute heart issues, are equipped with electrocardiogram (EKG),
cardiopulmonary resuscitation (CPR) kits, and defibrillators, and are
staffed by specialized teams. A “Healthy Heart Clinic” program screens
patients for cardiac risk factors. The future plan includes expanding
the CPU network nationwide, potentially serving as a model for other
countries grappling with CVDs. This approach could also apply to other
acute diseases requiring timely treatment for improved outcomes.

Exposure of parenteral nutrition (PN) to light induces hydroperoxides
(HPO) formation whose toxicity, especially in pediatrics, is documented.
In this context, we evaluated the efficacy of photoprotection medical
devices used in our institution to protect PN from degradation after two
different exposures to light. A mixed oil lipid emulsion (Smoflipid®) in
standard or opaque syringes and a ternary PN mixture bags (Numetah®)
with or without opaque overwrap were exposed for at least 420min to a
xenon lamp. Samples of Smoflipid® in standard or opaque syringes were
also exposed for 24h to conditions reproducing those of a neonatal
intensive care unit. The use of opaque syringes for Smoflipid®
administration or opaque overwraps for Numetah® administration reduced
HPO formation by an average of 14% and 40%, respectively, compared to
standard conditions after at least 420min to a xenon lamp. When
Smoflipid® samples were administered with standard or opaque syringes
and exposed to a phototherapy lamp, the fold-change in the HPO
concentration increased, respectively, by 6.3 or 5.4 at 24h compared
with syringes unexposed to phototherapy lamp. Although the observed
differences were non-significant, it nonetheless appears prudent to use
photoprotection of PN during administration, particularly in patients
with immature or compromised antioxidant capacity.
Enhancing Outlier Detection in Air Quality Index Data Using a Stacked Machine Learning Model
Authors: Diallo Abdoul Aziz , Nderu Lawrence , Malenje Bonface , Kikuvi Gideon
Published: August 2023

Air quality is an important part of environmental health, having serious
consequences for human health and well-being. The Air Quality Index
(AQI) is a frequently used metric for assessing air quality in various
areas and at different times. However, AQI data, like many other types
of environmental data, can contain outliers - data points that deviate
significantly from other observations, indicating exceptionally good or
poor air quality, a critical step in identifying and understanding
extreme pollution episodes that can have serious environmental and
public health consequences. These outliers can be caused by a variety of
variables, including measurement mistakes, odd meteorological
circumstances, and pollution occurrences. While outliers can
occasionally give useful information about these unusual conditions,
they can also skew studies and models if they are not adequately
accounted for. This paper describes a hybrid method for detecting
outliers in data, AQI data are used in this study. The model uses a
stacked machine learning model that incorporates K-means clustering,
Random Forest (RF), and Gradient Boosting Classifier (GBC). K-means is
used for initial categorization, followed by RF model training, and
ultimately, the RF output is used as input for the GBC to generate the
final classification. The performance of this stacked machine learning
model is examined and compared to single models using the Accuracy
measure. The findings show that the suggested technique is efficient,
with an accuracy of 0.99, showing its potential for effective outlier
detection in data.
Output Consensus Robustness and Performance of First-Order Agents
Authors: Qi Tian , Peng Hui , Ding Yanling , Chen Jie
Published: August 2023

In this paper, we study consensus robustness and performance problems
for continuous-time multi-agent systems. We consider first-order
unstable agents interconnected by an undirected graph, coordinated by a
delayed output feedback protocol. Our objectives are twofold. First, we
seek to determine the largest range of delay permissible so that the
agents may achieve robustly consensus despite variation of the delay
length, herein referred to as the delay consensus margin. Second, we
attempt to determine consensus error performance quantified under an H 2
norm criterion, which measures the disruptive effect of random nodal
noises on consensus. For both problems, we obtain analytical solutions.
The explicit expressions provide conceptual insights and exhibit how the
agents’ unstable pole, nonminimum phase zero, as well as the network
topology may limit fundamentally the consensus robustness and
performance.
Unveiling the mechanism of attaining high fill factor in silicon solar cells
Authors: Gao Pingqi , Lin Hao , Wang Genshun , Su Qiao , Han Can , Xue Chaowei , Yin Shi , Fang Liang , Xu Xixiang
Published: August 2023

A world record conversion efficiency of 26.81% has been achieved
recently by LONGi team on industry-grade silicon wafer (274 cm
, M6 size). An unparalleled high fill factor (
FF) of up to 86.59% boosted the cell performance. The
theoretical FF limit has been predicted to be 89.26%, while the
practical FF is far below this limit for a prolonged interval due
to the constraints of recombination ( i.e., SRH recombination)
and series resistance. The ideality factor ( m) in the equivalent
circuit of silicon solar cells is consistently ranging from 1 to 2 and
rarely falls below 1, resulting in a relatively lower FF than
85%. Here, this work complements a systematic simulation study to
demonstrate how to approach the FF limit in silicon solar cell
fabrication. Firstly, a diode component with an ideality factor equal to
2/3 corresponding to Auger recombination is incorporated in the
equivalent circuit for LONGi’ ultra-high FF solar cell; Secondly,
an advanced equivalent circuit is put forward for comprehensive analysis
of bulk recombination and surface recombination on the performance, in
which specific ideality factors are directly correlated with various
recombination mechanisms exhibiting explicit reverse saturation current
density ( J); Finally, we evaluate precisely
the route for approaching theoretical FF in practical solar cell
fabrication based on electrical design parameters using the developed
model.
A case report of organizing pneumonia in a children with M ycoplasma pneumoniae infection and gastroesophageal reflux

Published: August 2023

Organizing pneumonia is a rare entity in childhood, particularly in
previously healthy children[1].Our case was a female child with
cough and shortness of breath as the first symptoms. Etiological tests
indicated Mycoplasma pneumoniae infection; however, standard
anti- Mycoplasma pneumoniae treatment was not effective.
Follow-up medical history showed that the child had abdominal pain and
vomiting in the past.Monitoring of esophageal pH for 24 hours revealed
pathologic acid reflux.A lung biopsy suggested mechanized pneumonia.
After standard treatment for Mycoplasma pneumoniae infection and
gastroesophageal reflux, atomized budesonide suspension, and oral
prednisone for nearly half a year, the chest CT lesions of the child
gradually recovered and the lung function improved.

Published: August 2023

This letter presents a simulation-based design of an in-line
coaxial-to-circular waveguide transition for converting the coaxial
transverse electromagnetic mode (TEM) to the circular waveguide TE11¬
mode over an octave bandwidth. The proposed transition consists of a
coaxial-to-rectangular waveguide converter and a rectangular-to-circular
waveguide transformer. The dimensions of the transition have been
optimized using a commercial simulation tool. The proposed transition
operates from 10.02 GHz to 21.90 GHz with reflection coefficient of less
than −20 dB and higher-order mode level of less than −27.8 dB.
Correcting for artificial heat in coupled sea ice perturbation experiments
Authors: Fraser-Leach Luke , Audette Alexandre , Kushner Paul J.
Published: August 2023

A common approach to assessing how polar amplification affects lower
latitude climate is to perform coupled ocean-atmosphere experiments in
which sea ice is perturbed to a future state. A recent critique by M.
England and others uses a simple 1-dimensional energy balance model
(EBM) to show that sea ice perturbation experiments add artificial heat
to the climate system. We explore this effect in a broader range of
models and suggest a technique to correct for the artificial heat
post-hoc. Our technique successfully corrects for artificial heat in the
EBM and a possible generalization of this approach is developed to
correct for artificial heat in an albedo modification experiment in a
comprehensive earth system model. However, this technique can not be
directly generalized to sea ice perturbation methodologies that employ a
“ghost flux” seen only by the sea ice model. Applying the correction
to the comprehensive albedo modification experiment, we find stronger
artificial warming than in the EBM. Failing to account for the
artificial heat also leads to overestimation of the climate response to
sea ice loss, and can suggest false or artificially strong
“tugs-of-war” between 19 low latitude warming and sea ice loss over
some fields, for example Arctic surface temperature and 20 zonal wind.
Enhancing climate predictions with combination of dynamical model and artificial neural network
Authors: He Zikang , Brajard Julien , Wang Yiguo , Wang Xidong , Shen Zheqi
Published: August 2023

Dynamical models used in climate prediction often suffer from systematic
errors that can deteriorate their predictions. We propose a hybrid model
that combines both dynamical model and artificial neural network (ANN)
correcting model errors to improve climate predictions. We conducted a
series of experiments using the Modular Arbitrary-Order Ocean-Atmosphere
Model (MAOOAM) and trained the ANN with input from both atmospheric and
oceanic variables and output from analysis increments. Our results
demonstrate that the hybrid model outperforms the dynamical model in
terms of prediction skill for both atmospheric and oceanic variables
across different lead times. Furthermore, we conducted additional
experiments to identify the key factors influencing the prediction skill
of the hybrid model. We found that correcting both atmospheric and
oceanic errors yields the highest prediction skill while correcting only
atmospheric or oceanic errors has limited improvement.
Heterogeneous Land-Surface Effects on TKE and Cloud Formation: Statistical Insights from LES Cases
Authors: Simon Jason Scot , Bragg Andrew D. , Chaney Nathaniel W.
Published: August 2023

To aid development of sub-grid scale (SGS) parameterizations for Earth
system models which consider heterogeneity in land-surface fields and
land-atmosphere coupling, results from large-eddy simulations of 92
shallow convection cases over the Southern Great Plains are presented
and analyzed. Each case is simulated with heterogeneous surface fields
obtained from an offline field-scale land-surface model, and with
spatially homogeneous surface fields with the same domain-wide mean
value. By comparing corresponding heterogeneous and homogeneous cases,
it is found that turbulent kinetic energy and liquid water path has a
high correlation with the spatial variance of the surface heat flux
fields. By further comparing the source of this correlation over the
range of wavelengths in the surface fields, it is found that the
majority of the heterogeneous land-atmosphere coupling is contained in
wavelengths of order 10 km and larger, suggesting an encouraging degree
of feasibility of including land-surface heterogeneity in global-scale
SGS parameterizations.

Crisaborole, a phosphodiesterase 4 (PDE4) inhibitor, has been approved for the treatment of mild to moderate atopic dermatitis. Atopic dermatitis is often associated with increased pain. Using a mouse model, this study investigated whether crisaborole suppresses pain associated with atopic dermatitis and the potential mechanisms underlying it. The mouse model for atopic dermatitis was developed by repeatedly applying MC903. MC903-treated mice had increased spontaneous scratching (itch-related behaviour) and wiping behaviour (pain-related behaviour). Crisaborole was topically applied to the cheek skin of MC903-treated mice, and it reduced both itch- and pain-related behaviours in these mice. Immunofluorescence staining revealed that crisaborole reduced neutrophil infiltration and interaction of neutrophils with sensory neurones. Intradermal injection of S100A8/A9, proinflammatory neutrophil mediator, enhanced not only itch-related behaviours evoked by histamine or chloroquine, but also pain-related behaviours evoked by capsaicin. Calcium imaging of mouse dorsal root ganglion neurones revealed that pretreatment with S100A8/A9 significantly increased calcium responses to histamine and capsaicin, and the proportion of chloroquine-sensitive neurones. These findings suggest that the PDE4 inhibitor reduces itch and pain, in part by inhibiting infiltration of S100A8/A9-containing neutrophils in a mouse model of MC903-induced atopic dermatitis.

Study of Presence of Selected Heavy Metals in the Fish of Lake Victoria as a Predisposing Factor to Lifestyle Diseases in the 21st Century
Authors: OO Fredrick
Published: August 2023

Journal of contemporary issues facing the 21st century is heavy metals poisoning, especially in foods consumed, and resulting into lifestyle diseases such as cancers. “What we eat, in what quantity, and how that food is produced, can be the difference between life and death.” Fish in Lake Victoria form the major source of protein among the majority of dwellers around this Lake. “In many places fish become so contaminated by the filth on which they feed as to be a cause of disease. This is especially the case where the fish come in contact with the sewage of large cities. When used as food they bring disease and death on those who do not suspect the danger. There are a majority of agricultural and industrial activities taking place at the lake side, and along the river banks leading into the lake resulting in contamination of aquatic animals, fish inclusive. These toxins can be transferred into the human body through consumption of the affected fish or aquatic animals in these water bodies. This research uses Atomic Absorption Spectroscopy to determine the presence and the levels of the Pb, and Cd in fish of Lake Victoria. ANOVA F-test was conducted to determine whether the distribution of selected heavy metals in separate fish tissues was dependent on the species of fish. The analysis was also used determine whether the concentrations of the heavy metals were dependent on fishing grounds. The F-test was conducted at (α=0.05) 95% confidence interval. Using the mean concentrations of the selected heavy metals in vivo, graphical analysis of the data was obtained using Microsoft Excel sheet (Version 2013) and comparatively determined using bar graphs. This research is important as it will help various locals on the choice of healthy meals by informing them whether the most commonly preferred fish dish is still healthy. It will also help various researchers in finding the solution to various lifestyle diseases and infections associated with various meals taken in a lifetime.
Determination of Aflatoxins in Dried Fruits of Afghanistan
Authors: P Abubaker
Published: August 2023

Aflatoxins are carcinogenic and toxic to human beings. In this research work, the amount of aflatoxins contamination in seventy-two samples of dried fruits; Such as; Almonds and Raisins from processed raisins and almonds in Kabul city and Kabul customs, including twenty-one sample of almonds with shells, seven samples of pistachios with shells, six samples of almonds without shells, ten samples of pistachios without shells and twenty-eight samples of red raisins by using fluorometer is determined. Quantitative results show that 15 samples have 4 or less than 4 ppb aflatoxin, 21 samples have 5-10 ppb aflatoxin and the rest 35 samples have 10-25 ppb of aflatoxin. Similarly, in 27 samples of the almond amount of aflatoxins has been investigated, in all almond samples under investigation, none of the samples contained more than 22 ppb aflatoxin, which could be used as food. Ten samples are containing 4 ppb and less aflatoxin. Factors that play a role in the production of aflatoxins in almonds include Moisture, heat, microscopic effects of insects and organisms, storage time of almonds, infection shield and some other conditions. From the study, it was concluded that a continuous and strict national monitoring plan is needed to improve quality and safety of dried fruits supply in Afghanistan.
The Role of Evaporate Cooling Storage Technology to Reduce PostHarvest Losses of Fruits and Vegetables: A Review
Authors: TT Alemu
Published: August 2023

Fruits and vegetables are perishable crops, which have high moisture content and short shelf life. Most Postharvest losses of fruits and vegetables occur due to lack of proper cold storage. According to most of research and review show, approximates 40-50% fruits and vegetables loss in the supply chain at globally level. In many Africa countries, postharvest losses are not properly documented but experts have projected the losses to be up to 80%. In Ethiopia, postharvest loss of fruits and vegetables is 50% due to lack of appropriate postharvest handling practice and storage technologies. The loss up to 50% could be caused due to biological and environmental factors. In order to reduce postharvest loss of fruits and vegetables the roles of low cost evaporative cooling storage technology is great. Evaporate cooling is the process by which temperature of substance reduced due to cooling effect from evaporation of water. It work best at dry and hot climate area when results in reduction of temperature and increase in relative humidity. This storage technology reduces postharvest losses of fruits and vegetables by controlling temperature, concentration of gases and relative humidity of the storage area. Therefore, the aim of this review paper is to review studies made by several researchers and reviewers on the roles of evaporate storage technologies in postharvest loss reduction of fruits and vegetables. This storage technology of fruits and vegetables produce available for sale increased 42% to 62% and enhances 10-15 % food security. So to mitigate or alleviate high postharvest loss of perishable crops using evaporative storage technology is very important and determinant
General Features of Food Import in Burkina Faso
Authors: I Diéni
Published: August 2023

The flow of food goods from producers and importers to consumers is ensured by a large number of traders, including wholesale and retail. Food imports are a socio-economic fact in Burkina Faso. Due to the structural but also cyclical inadequacy of national production to meet the population’s needs for food, it has seen a significant rise in recent years. The purpose of this study was to investigate the traits of imports and the actor typology. From February to April 2020, 245 freight forwarders, 60 importers of placali and attiéké, and 57 phytosanitary inspectors were interviewed at 19 border crossings in Burkina Faso. The results showed that the import is formal (97.14%) and that the freight forwarders were mostly men (88.67%) who were mostly without proper training (57.33%) and who had an average age of 33 years with 59.18% who had secondary level. However, 90% of importers of attiéké and placali were women working in the informal sector (100%). In addition, 39.67% of the profits of these actors were intended for the maintenance of families and 37.38% for savings. Given the sector’s social and economic significance, greater supervision is necessary to ensure a healthy diet.
