Mechanism of Small Molecule Inhibitors of Phagocytosis

Published on: 3rd July, 2023

Immune cytopenias occur when the body produces antibodies that target specific hematopoietic cells, inducing extravascular antibody-mediated phagocytosis by monocyte-macrophages in the spleen and/or liver through activation of Fcγ Receptors (FcγRs). Immune cytopenias include Immune Thrombocytopenia (ITP), Autoimmune Hemolytic Anemia (AIHA), Hemolytic Transfusion Reactions (HTR), Hemolytic Disease of the Fetus and Newborn (HDFN), and Autoimmune Neutropenia (AIN). Thus, novel therapeutics that inhibit phagocytosis would be useful, especially for short-term use while other therapies are being evaluated. In our earlier studies, we successfully identified two small-molecule drugs able to inhibit in vitro phagocytosis with a low IC50 concentration and negligible toxicity. These drugs, known as KB-151 and KB-208, have the potential to be utilized as lead compounds for further studies, once their mechanism of action is more clearly understood. In this regard, we have developed preliminary results that suggest that these small molecules may bind to the Fc receptors on monocyte macrophages and block the subsequent attachment of antibody-opsonized red blood cells to prevent phagocytosis.

The Combinatory Effects of Zinc Oxide Nanoparticles (ZnO NPs) and Thiamine on Skin of Alloxan-Induced Diabetic Mice; a Stereological and Biochemical Study

Published on: 3rd July, 2023

This study aimed to investigate the treatment effects of ZnO NPs plus thiamine on histo-stereological and biochemical parameters in diabetic mouse skin. In total 54 BALB/C mice were used and divided into nine groups. Twenty-four mice were coordinately assigned as control groups (I), thiamine (II), and zinc oxide nanoparticles (III and IV; 1.0 and 5.0 mg/kg). Diabetes was induced in the remaining rats with a dose of 180 mg/kg of alloxan; diabetes group (group V). Other diabetic mice were treated with ZnO NPs (0.1 and 0.5 mg/kg) alone (groups VI and VII, respectively) and along with thiamine (groups VIII and IX, respectively). An increase in weight was observed in the diabetic group compared to the control group. Diabetic skin showed decreasing in volume density of collagen bundles and decreasing in the epidermis and dermis thickness, as well as an increase in the hypodermis's thickness. Administration of ZnO NPs (0.1 and 0.5 mg/kg) alone and along with thiamine in the diabetic animals resulted in anti-hyperglycemic activity, reducing GGT, BUN, Cr, MDA, and NO levels in treated diabetic mice. In conclusion, the concomitant use of ZnO NPs along with thiamine presents the potential as a combination therapy for the treatment of alloxan-induced diabetic mice skin changes.

Management of Fungal Diseases of Temperate Rice in the Kashmir Valley, India

Published on: 4th July, 2023

Over half of the world's population is fed by rice. It is consumed as a staple food by many countries worldwide. It is affected by a number of diseases among which fungal diseases contribute to its significant loss. Kashmir Valley located in the North Western Himalayan region of India is known for various coarse varieties of rice for their taste and elite class. However, the diseases cause a serious problem for the local farmers as well as the people who also consume rice as their staple food. One of the best remedies for disease management is the adoption of integrated disease management strategies, which include the use of resistant varieties, cultural practices, and judicious use of fungicides. In this review, we present the major fungal diseases affecting rice in Kashmir Valley and their management using Integrated Plant Disease Management (IDM).

Evaluation of Biostimulants Based on Recovered Protein Hydrolysates from Animal By-products as Plant Growth Enhancers

Published on: 3rd July, 2023

Free amino acids-based biostimulants are gaining momentum in Europe for sustainable agriculture. They stimulate plant growth, improve crop productivity, and reduce reliance on harmful fertilizers. Enzymatic hydrolysis is used to develop biostimulants from animal by-products, such as greaves and protein-rich wastewater from processed animal proteins. The effectiveness of enzymatic hydrolysis depends on selecting the appropriate conditioning stage for the by-products, yielding protein in the range of 86% to 97%. These protein hydrolysates, with optimal amino acid compositions, are evaluated as biostimulants. Promising results show growth improvements of 17% to 31% in Chinese cabbage and lettuce seeds. The optimal dilution concentration ranges from 0.05% to 0.3%, depending on the protein hydrolysate used. The findings highlight the potential of these biostimulants to enhance plant growth and productivity while reducing environmental impact by replacing chemical fertilizers. They offer sustainable alternatives for promoting environmentally friendly practices in agriculture.

Digital Health Opportunities and Risks: The Psychological Field

Published on: 30th June, 2023

The digital transformation in the health sector represents an extraordinary challenge not only concerning patient care and assistance processes but also for the purpose of promoting new models capable of responding to the growing complexity of the environment and its impact on health. Psychological services are among the non-medical healthcare services heavily invested by this radical transformation. The constant increase in online psychology demand by users follows the need to carefully regulate its practice since this digital space, virtually a non-place, is the focus of large commercial interests. Being a part of the application of digital technologies to psychological performance, the aim of the paper was to emphasize clinical work, especially focused on childhood and adolescence with the need of identifying the limits and problems of digital health psychology in this group of subjects. Considering also that the massive use of digitization in healthcare also raises considerations of a bioethical nature regarding the priority of the principle of patient autonomy in the complex and articulated process of healthcare and protection. In conclusion, although TM is spread in our area in an uneven way, the representations of TM are mostly positive. However, it seems to emerge a picture in which part of some professionals still look to be too cautious and resist this new way.

Snapshot of the Involvement of Glutathione in Plant-Pathogen Interactions

Published on: 27th June, 2023

Glutathione (GSH), a dynamic biomolecule, is popularly called the “master antioxidant”. This tripeptide thiol is almost ubiquitously found in prokaryotes, and eukaryotes, with some organism exceptions, and is known for its several significant roles including in plants. GSH in plant systems restricts itself not only to plant growth and development but its role is crucial in providing resistance to plants against several environmental hazards also.

Neonatal Mortality Rate among Twin and Singleton Births with the Gestational Age of 34-37 Weeks: A Population-Based Study

Published on: 28th June, 2023

Introduction: Twin pregnancy, compared to a singleton pregnancy, is associated with a higher risk of preterm birth and other neonatal complications. This study aimed to compare neonatal mortality rates and risk factors among births with the gestational age of 34 weeks - 37 weeks in twin and singleton pregnancies.Methods: The study design was cross-sectional and population-based. We extracted the data from the birth information registry in Iran. Mothers' and neonates' information was removed from the registry systems between 2018 and 2020. We used Statistical R software to compare neonatal mortality rate, demographic variables, and risk factors between two groups of twin and singleton neonates.Results: Out of 579,873 live births with a gestational age of 34 weeks - 37 weeks, 729 (1.4/1000) singleton and 54(0.77/1000) twins (one out of two) neonates died in the delivery room in the first hour of life. Of the neonates who left the delivery room alive, 3129 (4.9 per 1000) neonates had died (5.7/1000 singleton and 3.04/1000 twin). The neonatal mortality rate in hospitalized singleton neonates (1.85%) was higher than twin group (1.06%). After adjustment of other variables, the mortality rate in twin pregnancy was significantly lower than in singletons (p value < 1/1000), with an odds ratio of 0.47 (CI: 0.39 - 0.55). Antenatal corticosteroid treatment in the twin group was significantly higher than in singletons.Conclusion: Twin neonatal mortality rate was lower than singletons in the neonates with gestational age 34 weeks - 37 weeks. Clinicians could consider these results for delivery timing in uncomplicated twin pregnancies. Antenatal corticosteroid therapy can be considered to reduce the mortality rate of late preterm neonates in resource-limited countries.

A Study of Complete and Incomplete Reactions of 12C + 169Tm System at Energy Range ≈ 4.16 –7.5 MeV/Nucleon

Published on: 26th June, 2023

An attempt was made in this study to measure the excitation functions of 169Tm(12C, 4n)177Re, 169Tm(12C, 5n)176Re, 169Tm(12C, αn)176Ta, 169Tm(12C, α2n)175Ta, 169Tm(12C, α3n) 174Ta, 169Tm(12C, α4n)173Ta and 169Tm(12C, 2α2n)171Lu reaction channels populated in the interaction of 12C projectile with 169Tm target were considered in order to investigate the mechanisms of complete and incomplete fusion reactions. The theoretically predicted excitation functions using the PACE4 code were compared with the previously measured excitation functions. For non α emitting channels cross-section values predicted by PACE4 in general were found to be in good agreement with the experimentally measured values. However, for α-emitting channels, the measured cross-section values were found to be higher than the values predicted by PACE4. The observed disagreement may be credited to projectile break-up in the vicinity of n-n interaction.

Harnessing Artificial Intelligence for Early and Evolution of Alzheimer’s Disease Detections and Enhancing Senior Mental Health through Innovative Art-Singing Therapies: A Multidisciplinary Approach

Published on: 28th June, 2023

The well-documented therapeutic potential of group singing for patients living with Alzheimer’s disease (PLAD) has been hindered by COVID-19 restrictions, exacerbating loneliness and cognitive decline among seniors in residential and long-term care centers (CHSLDs). Addressing this challenge, the multidisciplinary study aims to develop a patient-oriented virtual reality (XR) interaction system facilitating group singing for mental health support during confinement and enhancing the understanding of the links between Alzheimer’s disease, social interaction, and singing. The researchers also propose to establish an early AD detection system using voice, facial, and non-invasive biometric measurements and validate the efficacy of selected intervention practices. The methodology involves co-designing an intelligent environment with caregivers to support PLAD mental health through online group singing, addressing existing constraints in CHSLDs. The researchers will engage volunteers in remote singing interactions and validate the impact of voice stimulation for PLADs using a control group. The primary expected outcome is the development of an “Intelligent Learning Health Environment,” fostering interactions while adapting to individual PLAD situations and incrementally accumulating knowledge on AD signs. This environment will facilitate the transfer of knowledge and technologies to promote non-verbal interactions via singing, enabling intervention at the first symptoms. Additionally, the research will contribute to transforming CHSLDs’ living environments, informed by neuroscience insights, and potentially extend the “collaborative self-care” approach to support seniors in aging safely and healthily at home.

An Urticaria Closet Simulating Leprosy in A 36-Year-Old Woman

Published on: 24th June, 2023

Urticaria corresponds to a papular edematous pruriginous fleeting rash on the skin whose cause is most often allergic (food, medicines, insect bites, etc.).Its management is often difficult because of its significant impact on quality of life. Its prevalence is estimated at 0.6% - 1.3% of the general population. Leprosy is a chronic infectious disease caused by Mycobacterium leprae (M. leprae) or Hansen’s bacillus (BH). Considered as the great simulator leprosy can pose a diagnostic problem with many other dermatological pathologies. This is a 36-year-old patient with a history of chronic urticaria treated with Loratadine 10 mg who consulted the Bamako Dermatology Hospital for a large erythematous cupboard, oedematous fixed on the buttocks evolving for more than 3 days. The interrogation found the notion of pruritus, hives, and physical examination, showed large erythematous plaques, edematous very limited, dark red color, and slightly copper resembling the closet infiltrated by leprosy. The pruriginous nature of the lesions and the absence of other cardinal signs of leprosy allowed us to make the diagnosis of chronic urticaria.
