Published: January 2025

Currently, soil moisture monitoring is only done manually, which is less accurate, even though sometimes we need a soil moisture monitoring tool to determine the soil water content in plants. This research uses a Soil Moisture sensor to measure soil moisture and the NodeMCU ESP8266 microcontroller as the main controller. The system is designed to provide accurate and efficient soil moisture monitoring through the Internet of Things (IoT). The integration of Blynk as a monitoring application offers easy access to real-time soil moisture data via mobile devices. This system is designed to help users monitor soil moisture in real-time using NodeMCU as the main platform and Blynk for user interaction. Through this system, it is expected that users can avoid the risk of water shortages by knowing the soil water content in real-time. Based on testing, this soil moisture monitoring product has a success rate of 88.2% for soil moisture accuracy and an average user satisfaction rate of 60%.

, in astrophysical observations of galactic, extragalactic, and black hole systems. This is a test of fundamental importance for self-organized criticality (SOC) systems. The test decides whether (i) power laws are a natural consequence of the scale-freeness and inherent universality of SOC systems, or (ii) if they depend on more complex physical scaling laws. The former criterion allows quantitative predictions of the power-law-like size distributions, while the latter criterion requires individual physical modeling for each SOC variable and data set. Our statistical test, carried out with 61 published data sets, is consistent with the former option, which implies that observed power laws can simply be derived from the scale-freeness and do not require specific physical models to understand their statistical distributions. The observations show a mean and standard deviation of α

F
= 1.78 ± 0.29 for SOC fluxes and α

E
= 1.66 ± 0.22 for SOC fluences, and thus are consistent with the prediction of the fractal-diffusive SOC model, with α

Lessons from the agrochemical ban: sustainable solutions to the adverse effects of intensive farming and their economic impact in rebuilding the nation
Authors: Sivaramanan S. , Kotagama S. W. 
Published: January 2025

This study based on literature survey, aims to find (valid) reasons for the negative consequences of the agrochemical ban in Sri Lanka. Intensive farming is one of the major environmental problems. To surmount the negative consequences of the agrochemicals, sustainable solutions such as agrochemical ban could be implemented. Yet, sustainable solutions are relatively expensive due to their high energy requirements. Thus, even affluent nations hardly go for such decisions. In contrast, regenerative solutions are wise, adaptable, high resilient, and relatively cheaper. A study claims that if Sri Lanka could have implemented regenerative methods such as holistic farm management and agroforestry without banning agrochemicals (a sustainable solution), in May 2021, contribution to the economic crisis of 2022 could have been avoided because, as an agriculture nation, its economy considerably depends on agriculture exports such as tea and rubber. The declined yield due to shifting to organic farming resulted into an inflation, which made the country unaffordable to the importation of fuel, medicines, food items, and other essential items, which subsequently ended up in a catastrophic public unrest and political transformation. However, restorative solutions are a step ahead of sustainable solutions, where more positive changes occur in nature under human maintenance, e.g., introducing ducks (as practiced in Thailand) and fishes and crabs (as practiced in China) into the fields as biological control agents, using natural Neem-based pesticides and using seaweeds as the organic replacement for the inorganic fertilizer. Reconciliatory solutions are cultural practices that bring positive changes to the nature, the main difference between restorative and reconciliatory solution is, in reconciliatory solution human being is considered as equal component within nature (as co-participant and co-creator with nature), but, in the restorative systems humans are like managers of the system (not co-participants), who monitor and handle the system. For instance, forest restoration is a restorative system that requires frequent maintenance and monitoring such as nurturing the new saplings (e.g. fencing the saplings), and this administrative role of humans is replaced by co-participation along with nature in the reconciliatory model. To further illustrate, carbon farming, biological nitrogen fixing (e.g., Azolla sp.) and bioremediation via floating wetlands could provide restorative solutions for the agrochemical pollution while traditional practices such as introducing ducks, fishes and crabs into the field as biological pest control agents, using sea weed mulching as an alternative for chemical fertilizers and using Neem based pesticides as an alternative for chemical pesticides give reconciliatory solutions to the crisis, humans are equal participants within the system.

Aglaonema ‘Maria’ is a popular indoor plant, which is vulnerable to soft rot, a bacterial disease that causes serious losses in nurseries and is a major barrier in producing export-quality planting materials. Biocontrol agents are the best eco-sustainable alternatives for agrochemicals in managing plant diseases. This study was focused on isolating the causative agent of soft–rot disease of Aglaonema ‘Maria’ and evaluating the biocontrol potency of Bacillus velezensis strain DCJ 2 (DCJ 2) in situ under different delivery methods. The causative bacterium isolated from infected Aglaonema ‘Maria’ plants, coded as KPJ 1 was subjected to morphological, and biochemical, molecular and physiological characterization. The tests were performed in duplicate, indicating that the bacterium was positive for all of the tests that should be positive, except the oxidase test, which should be negative. The bacterium was tested to be gram-negative. Molecular characterization revealed that the KPJ 1 is Dickeya fangzhongdai. A pot experiment with healthy plants of Aglaonema ‘Maria’ was carried out to evaluate the biocontrol potency of DCJ 2 on KPJ 1 using a Completely Randomized Design with eight treatments and six replications. T1 and T2 represented untreated controls whereas the plants inoculated with only the pathogen (KPJ 1) considered as the negative controls [T3 (drench) and T4 (foliar spray) ]. T5 and T6 represented the plants treated sequentially with KPJ 1 and DCJ as a soil drench. Similarly, foliar spray was performed in the T7 and T8. The data were analyzed using SAS software (version 9). Among both inoculum application protocols T5 and T6 (soil drench) showed the lowest disease severity (p=0.05). In conclusion, the antagonistic bacterium DCJ 2 demonstrated potent activity against soft-rot disease in Aglaonema caused by D. fangzhongdai which could be effectively used as an eco-friendly biological control agent in Aglaonema nurseries.
Osteopontin expression in psoriasis versus lichen planus: a comparative immunohistochemical study
Authors: Hassan Ghada F.R. , Ellebidy Esraa S.H. , Elazeem Marwa A.E.A. , Elhawary Esraa E. 
Published: January 2025

Background
Psoriasis is a complex immune-mediated chronic inflammatory disorder triggered by various risk factors in genetically susceptible individuals, while lichen planus (LP) is a chronic inflammatory, immune-mediated disease. Osteopontin (OPN) is a phosphorylated acidic glycoprotein produced by several cell types and involved in immune regulation, cellular signaling, inflammation, and vascularization, and plays a role in various physiological and pathological processes. While the literature has many studies regarding OPN expression in psoriasis and oral lichen, no studies were done on cutaneous LP. Furthermore, no comparison between psoriasis and cutaneous LP was made.

Objective
To evaluate OPN expression in psoriasis versus LP as the most common papulosquamous skin disorders in comparison with healthy patients to study its possible role in the pathogenesis of both diseases.

Patients and methods
This comparative study included 40 patients with psoriasis and 40 patients with LP, in addition with 20 healthy individuals as the control group. Skin biopsies were obtained and stained with H and E. Immunohistochemical staining of sections was performed using a human polyclonal anti-OPN IgG antibody to evaluate epidermal and dermal OPN expression in psoriasis and LP sections versus control.

Results
There was a statistically significant decrease in epidermal OPN expression in the patients of both diseases when compared with the control group, but a statistically significant increase in the dermal expression of OPN in both diseases when compared with the control group. In addition, a statistically significant increase in OPN expression was detected in the epidermis of the psoriasis group in comparison with the lichen group. Higher expression of dermal OPN expression is related to severity of the psoriasis area severity index score in psoriasis patients and to the lichen planus severity index in LP.

Conclusion
Due to its significant dermal expression in psoriasis and LP immunohistochemically stained sections, OPN might have an essential role in the pathogenesis of both diseases, and the level of its expression in tissues could indicate the severity of psoriasis and LP.
The relationship between Helicobacter pylori and pityriasis versicolor
Authors: El Samahy May H. , Abdelrahman Raafat Z. , Ibrahim Hossam O. , Mostafa Azza E. 
Published: January 2025

Background
Although the immune dysregulation caused by Helicobacter pylori has been linked to the pathogenesis of many dermatological diseases, the link between H. pylori infection and pityriasis versicolor (PVC) has not been largely verified.

Objective
To study the probable association between active H. pylori infection and PVC prevalence and clinical parameters.

Patients and methods
The present case control study included 65 male patients with PVC (group A) and 65 dermatologically free patients (group B). Active H. pylori infection was detected in both groups using H. pylori stool antigen test (SAT). In group A, patients who tested SAT positive were subjected to measurement of anti-H. pylori immunoglobulin (Ig)G and IgA and interleukin (IL)-10 serum levels.

Results
The frequency of H. pylori was equal (61.5%) in both study groups. The various clinical parameters of PVC did not significantly differ between SAT-positive and SAT-negative patients. In group A, H. pylori-infected patients had elevated IgG and IgA serum titer, while IL-10 level was in most cases (65%) low. No significant relation was detected between the H. pylori serological markers and the PVC clinical parameters.

Conclusion
Active H. pylori infection did not impact the prevalence or clinical features of PVC. Elevated H. pylori IgG and IgA levels did not vary differentially in relation to PVC clinical features. Moreover, serum IL-10 level in active H. pylori-infected patients with PVC was not elevated. Accordingly, its role as a systemic immunosuppressive cytokine predisposing for PVC was unverified in this study.
Patient-derived VIDA and dermoscopy versus sequential planimetry for assessing activity in vitiligo patients receiving narrowband ultraviolet B: a comparative longitudinal study
Authors: El Eriny Ali F. , Elmorsy Eman H. , Farid Carmen I. , Elrashidy Maha E. 
Published: January 2025

Background
Judging the stability/activity of vitiligo is of therapeutic and prognostic significance. Clinical and biochemical activity indicators are available, but none is currently universally accepted.

Objective
To compare the accuracy of patient-derived vitiligo disease activity score (VIDA) and dermoscopy, versus sequential planimetry in determining vitiligo stability/activity.

Patients and methods
A total of 120 nonsegmental otherwise healthy vitiligo patients were included, who reported disease stability for the last 6 months. Global assessment and photography were followed by choosing a stable non-repigmenting lesion for longitudinal evaluation of planimetric changes, and dermoscopy. Patients received the standard protocol of narrow band ultraviolet B for 3 months, and patient recall for global and lesional progression was recorded. Accuracy of patient-derived VIDA and dermoscopic signs, versus planimetric changes as the reference were compared for judging vitiligo stability/activity.

Results
Patient-derived VIDA showed 58.33% accuracy in determining disease stability while Dermoscopy showed 97.50% overall accuracy. The absence of a pigment network and the absence of signs of activity (collective absence of ill-defined border, satellite lesions, and microkoebnerization) showed 100% accuracy in establishing disease stability. On the other hand, the presence of any microkoebnerization, starburst sign, or satellite/tapioca sago sign was 100% indicative of activity. Border definition gave a 91.67% overall accuracy for judging stability, while Perifollicular pigmentation showed an accuracy of 49.17%.

Conclusion
Patient-derived VIDA is generally unreliable, whereas longitudinal follow-up for planimetric changes, and dermoscopic assessment are of better reliability. The absence of pigment network, and collective absence of ill-defined border, microkoebnerization, and satellite lesions are 100% accurate in predicting stable vitiligo.

Published: January 2025

Background
Treating depressed atrophic scars, which can result from various causes like post-trauma, acne vulgaris, and varicella, can be challenging. Still, there are several therapeutic modalities available that can help improve their appearance. Developing a method that is easy, safe, and effective in treating depressed scars is a significant goal in dermatology and aesthetics.

Objective
To assess the efficacy of autologous dermal tissue transplantation in correcting atrophic scars due to trauma, acne vulgaris, varicella infection, and other inflammatory diseases and to evaluate any side effects associated with the procedure.

Patients and methods
Eleven patients with depressed atrophic scars willing to undergo the procedure were selected. Dermal tissue harvested after removing the epidermis by dermabrasion, was cut into small pieces, and inserted in the dermis of the recipient site with the help of 18 G needle. 2 experienced dermatologists did assessment of results by using clinical assessment scores.

Results
Out of 11 patients, one patient showed a 25–50% improvement, six patients showed improvement between 51 and 75%, and four patients showed more than 75% improvement. Improvement was good in small linear scars. Milia-like lesion developed in one patient.

Conclusion
Autologous dermal tissue transplantation is effective in depressed scars. The technique is safe, cheap, and can be mastered easily. It is important to continue conducting research and clinical trials to establish the benefits and limitations of autologous dermal tissue transplantation for depressed scars. Additionally, long-term follow-up studies can provide insights into the durability of the treatment results.
