Rice-husks synthesized-silica nanoparticles modulate silicon content, ionic homeostasis, and antioxidants defense under limited irrigation regime in eggplants

Research Abstract

The utilization of nanoparticles in agricultural land is widely increasing worldwide. The present study takes the
advent from converting the rice husk waste to silica nanoparticles (SiNPs) to be used in two years of field experiments,
as fertigation treatment, against reducing irrigation by drip system. In this respect, the experiments
comprised of three drip irrigation regimes (i.e., 60, 80, and 100 % of crop evapotranspiration, ETc) and four
levels of SiNPs (0, 100, 200, and 300 mg L? 1). The results indicated that limited irrigation reduced the plant fresh
weight, plant height, and yield of eggplants by 15, 25, and 30 %, an average of two years, at the level of 60 % ETc
compared to 100 % ETc. However, these negative impacts were alleviated by SiNPs via improving the photosynthetic
pigments and relative water content where the plants supplemented with 300 mg L? 1 SiNPs had the
highest improving effects to be 3.8 mg g? 1 FW and 76 % compared to 2.2 mg g? 1 FW and 63 % (average of two
years), respectively at the drought level of 60 % ETc. Furthermore, SiNPs ameliorated the oxidative damage
induced by different water regimes by lessening lipid peroxidation and hydrogen peroxide (10.9 and 85.4 μM g? 1
FW) compared to their drought level 60 % ETc (14 and 113 μM g? 1 FW). This was associated with stimulating the
antioxidant enzyme system by promoting the activities of peroxidases (ascorbate- and guaiacol-dependent types),
catalase, and superoxide dismutase as the concentration of silica NPs increased to be (173.84, 12.2, 49.5, and 41
unit/mg/min, respectively) at 60 % ETc and 300 mg L? 1 SiNPs compared to only 60 % ETc (100.5, 7.9, 32, and
30.5 unit/mg/min, respectively). Also, efficiently increasing SiNPs levels highly significantly restrained the ionic
homeostasis in the leaves of eggplant via retaining the reduction of silicon, potassium, calcium, and magnesium
contents at 300 mg L? 1 silica NPs especially at 60 % ETc (33, 19, 4.5, and 6 mg g? 1 DW, respectively) compared
to the corresponding drought level (17.33, 7, 2.1, and 3.7 mg g? 1 DW, respectively) which reflected on the upregulation
of water status. Such amelioration effects of SiNPs were recommended during the two studied seasons.
Altogether, the synthesized SiNPs efficiently mitigated the negative impacts of limited drip irrigation levels on
ionic homeostasis, pigments, oxidative stress, and antioxidant system especially at the level of 300 mg L? 1

Expression profile of serum LncRNAs MALAT-1 and CCAT-1 and their correlation with Mayo severity score in ulcerative colitis patients can diagnose and predict the prognosis of the disease

Research Abstract

identified as a precancerous lesion for colorectal cancer. Up-to-date genomic research revealed the value of many
noncoding RNAs (ncRNAs) in UC pathogenesis, diagnosis, and prognosis.
Aim: The present study was aimed at measuring both MALAT-1 and CCAT-1 in the sera of UC patients as
diagnostic and prognostic biomarkers and correlating them with the Mayo score which is a novel predictive
indicator of malignant transformation as well as with clinicopathological characteristics of the disease.
Patients and methods: Sixty-six UC patients and 80 healthy individuals participated in this study, the serum fold
changes of MALAT-1 and CCAT-1 were measured by using quantitative real-time PCR (qRT-PCR).
Results: The current study findings include overexpressed lncRNAs MALAT-1 and CCAT-1 in the sera of ulcerative
colitis patients [(median (IQR) = 2.290 (0.16–9.36), mean ± SD = 3.37 ± 3.904 for MALAT-1, and median
(IQR) = 7.305 (0.57–16.96), mean ± SD = 6.81 ± 4.002 for CCAT-1 than controls, ROC curve analysis reported
that these genes could predict UC. Both genes were positively correlated with each other which enforces their
synergistic effects. Both genes are diagnostic for UC patients.
We related studied genes to the severity of the disease. In addition to a significant positive correlation between
each gene with ESR and Mayo score, we further classified the patients according to severity (according to Mayo
score to remission, mild, moderate, and severe groups) with the following results; lower levels of MALAT-1 and
CCAT-1 were significantly associated with mild disease and increased gradually with more severe forms of the
disease (p < 0.05). Linear regression analysis with Mayo Score as a dependent variable revealed that only the
predictive power of CCAT-1 and ESR are significant. Moreover, ROC curve analysis when compared to that of the
Mayo score revealed that CCAT-1 reached 99 % accuracy. In summary, both genes are prognostic factors for UC
patients.
Conclusion: MALAT-1 and CCAT-1 are diagnostic and prognostic serum biomarkers of ulcerative colitis.

METABOLIC MYOPATHIES (MMS)

Research Abstract

Abstract: Metabolic myopathies are a group of inherited illnesses affecting skeletal muscle metabolism due to enzymatic deficiencies in glycogen breakdown, fatty acid oxidation, or mitochondrial energy production. These disorders result in exercise intolerance, muscle weakness, & rhabdomyolysis (muscle breakdown resulting in the release of toxic cellular components into the bloodstream), which may progress to chronic muscle degeneration and functional impairment. Diagnosis relies on clinical symptoms, biochemical markers, genetic testing, and muscle biopsy. Common disorders include glycogen storage diseases like McArdle illness, which impairs glycogen breakdown, fatty a` oxidation disorders like carnitine palmitoyl transferase II deficiency that disrupts lipid metabolism, and mitochondrial myopathies, which affect cellular energy production. Management strategies focus on dietary modifications, including tailored carbohydrate or fat intake, controlled exercise programs to prevent muscle damage, and novel therapies like enzyme replacement treatment and gene therapy. Supportive treatments, including symptom management and physical therapy, also play a crucial role in improving mobility & overall well-being. Early diagnosis and individualized interventions are essential for optimizing patient outcomes, minimizing complications, and enhancing quality of life. Continued research into the molecular mechanisms of these disorders is vital for developing more effective therapies and improving longterm prognosisAbstract: Metabolic myopathies are a group of inherited illnesses affecting skeletal muscle metabolism due to enzymatic deficiencies in glycogen breakdown, fatty acid oxidation, or mitochondrial energy production.
