Microwave-assisted Green Synthesis: An Approach for the Development of Anti-tubercular Agents
Tuberculosis (TB) is a serious infectious disease that primarily affects the lungs but can also spread to the brain and spine. The highly pathogenic bacteria that causes TB is called Mycobacterium tuberculosis (Mtb). Usually, when an infected person coughs, sneezes, or speaks, the disease spreads through the air. TB is treatable with antibiotics, but it requires a long course of treatment, usually 6 to 9 months to eliminate the bacteria and prevent drug resistance. Thus, developing novel anti-tubercular therapeutics with various structural classes is necessary to solve the problems brought on by strains that are resistant to several currently available therapies. Resistance to widely used anti-tubercular drugs is increasing daily. As a result, continuing medication therapy is necessary to stop more microbial infections. However, it leads to treatment resistance, which increases the likelihood that the disease may resurface in immune-compromised patients. Several anti-tubercular medications with various molecular structures show appropriate anti-tubercular action against Mycobacterium TB strains that are drug-sensitive and drug-resistant. Compared to conventional synthetic methods, synthetic reactions can be carried out more effectively and selectively under simple reaction conditions by employing microwave radiation. Microwave-assisted organic synthesis (MAOS) is a useful method for increasing product yield and selectivity while accelerating the reaction rate for different types of organic synthesis. Several lead compounds with anti-tubercular properties that were synthesized using the microwave irradiation (MWI) approach are discussed in the current work.

Therapeutic Aspects of Melatonin-sirtuin Crosstalk: An Updated Review of Current Data Based on Cellular Mechanisms
Melatonin, a master regulator of circadian rhythms and diverse physiological processes, exhibits complex interactions with various molecules. Sirtuins, a family of histone deacetylases, are key players in aging, stress responses, and metabolism and represent a critical target for melatonin. This review explores the multifaceted functions of melatonin and sirtuins, delving into the molecular mechanisms of their interaction. We further examine the impact of this synergy on various pathologies across different organs. Studies suggest that melatonin modulates SIRT1 and SIRT3 signaling pathways, offering protection in neurodegenerative, cardiovascular, skeletal, and pulmonary diseases, as well as renal and hepatic dysfunction. Additionally, melatonin-sirtuin interactions have been implicated in mitigating cancer development and promoting health in the female and male reproductive systems. Notably, the majority of studies across these systems demonstrate melatonin's ability to regulate SIRT1 and SIRT3 signaling, thereby alleviating associated pathologies. In conclusion, the intricate interplay between melatonin and, particularly, SIRT1 and SIRT3 emerges as a crucial modulator of diverse signaling pathways, with promising therapeutic implications for a wide range of diseases.

Neurostimulation for the Management of Epilepsy: Advances in Targeted Therapy
BackgroundEpilepsy is a multifaceted neurological disorder marked by seizures that can present with a wide range of symptoms. Despite the prevalent use of anti-epileptic drugs, drug resistance and adverse effects present considerable obstacles. Despite advancements in anti-epileptic drugs (AEDs), approximately 20-30% of patients remain drug-resistant, highlighting the need for innovative therapeutic strategies.
AimThis study aimed to explore advancements in epilepsy diagnosis and treatment utilizing modern technology and medicines.
MethodsThe literature survey was carried out using Scopus, ScienceDirect, and Google Scholar. Data from the last 10 years were preferred to include in the study.
ResultsEmerging technologies, such as artificial intelligence, gene therapy, and wearable gadgets, have transformed epilepsy care. EEG and MRI play essential roles in diagnosis, while AI aids in evaluating big datasets for more accurate seizure identification. Machine learning and artificial intelligence are increasingly integrated into diagnostic processes to enhance seizure detection and classification. Wearable technology improves patient self-monitoring and helps clinical research. Furthermore, gene treatments offer promise by treating the fundamental causes of seizure activity, while stem cell therapies give neuroprotective and regenerative advantages. Dietary interventions, including ketogenic diets, are being examined for their ability to modify neurochemical pathways implicated in epilepsy.
ConclusionRecent technological and therapeutic developments provide major benefits in epilepsy assessment and treatment, with AI and wearable devices enhancing seizure detection and patient monitoring. Nonetheless, additional study is essential to ensure greater clinical application and efficacy. Future perspectives include the potential of optogenetics and advanced signal processing techniques to revolutionize treatment paradigms, emphasizing the importance of personalized medicine in epilepsy care. Overall, a comprehensive understanding of the multifaceted nature of epilepsy is essential for developing effective interventions and improving patient outcomes.

RAAS Overactivation and Mitochondrial Damage Signaling as Key Players in Lethal COVID-19
Authors: Sabrina Fulkerson, Grace Hohman, Tyler Stark, Selman Aydogdu and Mohamed EldeebCoronavirus disease 2019 (COVID-19), which led to a global pandemic causing millions of deaths, is caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). While previous research on COVID-19 has primarily utilized nasal swabs and blood samples, these do not provide comprehensive insights into all the organ systems affected by the infection. A recent study by Topper et al. addressed this gap by analyzing both nasal samples and autopsy tissues from SARS-CoV-2-infected individuals. Their findings highlight a significant role of mitochondrial damage pathways and RAAS overactivation in contributing to the severity of SARS-CoV-2 infections. Importantly, targeting mitochondrial dysfunction and RAAS overactivation pathways may offer promising and specific druggable targets for treating COVID-19 patients.

GSTP1, PRDX2 and NFE2L2: Potential Markers for Primary Stage Breast Cancer
IntroductionBreast cancer incidence and mortality have continued to rise over the past few decades. Despite advancements made in clinical research, the most imperative feature of breast cancer management is the diagnosis at the earliest stages. The current focus of the study is to identify and quantify differentially expressed oxidative stress-related proteins as putative early-stage markers for breast cancer.
MethodsNormal and cancerous breast tissue samples (n = 40) were collected after approval from the institutional bioethics committee (IBC) and with patient's consent. A label-free proteomic approach was used to quantify oxidative stress-related proteins. Gene expression of GSTP1, PRDX2, HSP90, NFE2L2, and miR-365a was quantified using RT-qPCR in all samples. Protein expression of PRDX2 and GSTP1 was further analyzed using immunohistochemistry.
ResultsThe protein and gene expression of PRDX2, GSTP1, and HSP90 were significantly upregulated (p < 0.05) in cancerous samples as compared to normal. However, gene and protein expression of the transcription factor NFE2L2 was significantly downregulated (p < 0.05) in diseased samples. OncomiR-365a was also significantly upregulated (p < 0.05) in cancerous samples. Immunohistochemical analysis also confirmed the upregulated expression of GSTP1 and PRDX2 in cancer tissues.
DiscussionOur study provides insight into the significant role of GSTP1, PRDX2, and NFE2L2 in the pathophysiology of the disease as early-stage breast cancer markers. It is suggested that altered expression of these key proteins could play a protective role in reducing the damage.
ConclusionIt can be concluded that GSTP1, PRDX2, and NFE2L2 may serve as predictive early-stage markers for diagnosis and potential therapeutic targets for breast cancer.
