Smart polymers represent a class of advanced materials that undergo reversible changes in their physical or chemical form and are known as responsive polymers. These polymers show transitions when external stimuli, such as temperature and pH, come into play. Smart polymers are being increasingly applied in various fields, such as drug delivery to a targeted site and gene therapy.

Introduction: Autism is a neurodevelopmental disorder associated with mitochondrial dysfunction, apoptosis, and neuroinflammation. These factors can lead to the overactivation of c-JNK and p38MAPK.

Methods: In rats, stereotactic intracerebroventricular (ICV) injection of propionic acid (PPA) results in autistic-like characteristics such as poor social interaction, repetitive behaviours, and restricted communication.

Multicomponent reactions (MCRs) have significant relevance in the field of synthetic chemistry, and in recent times one of the MCR variants, named the Groebke-Blackburn-Bienaymé (GBB) reaction, has attracted massive attention for the synthesis of biologically important scaffolds. The present review elaborates on the chemical advancement reported for the GBB reaction with an emphasis on the role of various catalytic systems. Further, the role of the GBB reaction has been redefined as a standard protocol for the synthesis of an array of potential bioactive compounds.

Article Synopsis
  • ALS is a progressive neurodegenerative disease affecting motor neurons, leading to severe motor dysfunction and respiratory failure, with varying global incidence primarily in individuals aged 45-80.
  • The disease is driven by genetic factors (like mutations in specific genes) and environmental influences, highlighting its complex pathogenesis involving protein misfolding, mitochondrial issues, oxidative stress, and neuroinflammation.
  • Current treatments focus on symptom management, with ongoing research into gene therapy and stem cell therapy, but effective solutions are still in early development, necessitating further exploration of ALS's genetics for targeted therapies.

Article Synopsis
  • Autism is a complex condition with symptoms like repetitive behaviors and social communication difficulties, linked to genetic, environmental, and dietary factors, as well as neurobiological issues including mitochondrial dysfunction and neurotransmitter imbalances.
  • Propionic acid (PRPA), produced by gut bacteria, can worsen autism symptoms; however, Genistein (GNT), a natural compound, shows potential for improving these symptoms through its effects on cellular signaling pathways and mitochondrial function.
  • Research using a rat model of autism demonstrated that GNT significantly enhances motor and cognitive skills, reduces neuroinflammation and brain injuries, and normalizes key biological markers, indicating its promise as a treatment for autism.

  • ALS is a serious neurodegenerative disease that weakens motor neurons, leading to muscle weakness and respiratory failure, influenced by factors like high glutamate levels and environmental toxins.
  • This study investigates the effectiveness of oleanolic acid (OLA) from olive trees in treating ALS, focusing on its ability to target specific harmful signaling pathways through various experimental methods on rats.
  • Results showed OLA significantly protects nerves, reduces inflammation, improves brain health, and enhances motor functions, especially when combined with another treatment, suggesting it could be a valuable addition to current ALS therapies pending further research.

SIRT1 (Sirtuin 1) is a NAD+-dependent deacetylase that functions through nucleoplasmic transfer and is present in nearly all mammalian tissues. SIRT1 is believed to deacetylate its protein substrates, resulting in neuroprotective actions, including reduced oxidative stress and inflammation, increased autophagy, increased nerve growth factors, and preserved neuronal integrity in aging or neurological disease. Nrf2 is a transcription factor that regulates the genes responsible for oxidative stress response and substance detoxification.

Obsessive-Compulsive Disorder (OCD), a prevalent neuropsychiatric condition, affects approximately 2%-3% of the global population. This paper provides an extensive overview of OCD, detailing its clinical manifestations, neurobiological underpinnings, and therapeutic approaches. It examines OCD's classification shift in the DSM-5, the role of the cortico-striatothalamo- cortical pathway in its development, and the various factors contributing to its etiology, such as genes, environmental factors, and genetic predispositions.

Multiple sclerosis [MS] is a progressive autoimmune condition that primarily affects young people and is characterized by demyelination and neurodegeneration of the central nervous system [CNS]. This in-depth review explores the complex involvement of oligodendrocytes, the primary myelin- producing cells in the CNS, in the pathophysiology of MS. It discusses the biochemical processes and signalling pathways required for oligodendrocytes to function and remain alive, as well as how they might fail and cause demyelination to occur.

The purpose of this study was twofold: to identify the growth mechanisms of amorphous nanoparticles in solution and during the drying process at high temperatures, and to guide the process condition and stabilizer selection for amorphous nanoparticle formulations. In contrast to nanocrystals that are mostly mechanically robust, amorphous nanoparticles tend to undergo deformation under stress. As a result, development of a stable formulation and evaluation of the drying process for re-dispersible amorphous nanoparticles present considerable challenges.

Introduction: Mucormycosis mostly targets immunocompromised patients or those with uncontrolled diabetes but is now an important complication after coronavirus disease 2019 (COVID-19) infection. The stage of mucormycosis at presentation greatly impacts its treatment course and prognosis. Prior research has failed to evaluate an association of patient factors, especially glycated hemoglobin (HbA1c) levels and random blood sugar (RBS) at presentation, with the stage and outcome of mucormycosis.

Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease that causes significant neurodegeneration. Methylmercury (MeHg+) is a neurotoxin that induces axonal neurodegeneration and motor nerve degeneration by destroying oligodendrocytes, degenerating white matter, inducing apoptosis, excitotoxicity, and reducing myelin basic protein (MBP). This study examines the inhibition of SIRT-1 (silence information regulator 1), Nrf-2 (nuclear factor E2-related factor 2), HO-1 (heme oxygenase 1), and TDP-43 (TAR-DNA-binding protein 43) accumulation in the context of ALS, as well as the modulation of these proteins by icariin (15 and 30 mg/kg, orally), a glycoside flavonoid with neuroprotective properties.
