Vaccination prior to SARS-CoV-2 infection does not affect the neurologic manifestations of long COVID.

Persistent symptoms after COVID-19 constitute the long COVID syndrome, also called post-acute sequelae of SARS-CoV-2 infection (PASC). COVID-19 vaccines reduce the gravity of ensuing SARS-CoV-2 infections. However, whether vaccines also have an impact on PASC remain unknown.

The 'Oma's of the Gammas-Cancerogenesis by γ-Herpesviruses.

Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV), which are the only members of the gamma(γ) herpesviruses, are oncogenic viruses that significantly contribute to the development of various human cancers, such as Burkitt's lymphoma, nasopharyngeal carcinoma, Hodgkin's lymphoma, Kaposi's sarcoma, and primary effusion lymphoma. Oncogenesis triggered by γ-herpesviruses involves complex interactions between viral genetics, host cellular mechanisms, and immune evasion strategies. At the genetic level, crucial viral oncogenes participate in the disruption of cell signaling, leading to uncontrolled proliferation and inhibition of apoptosis.

An In-Vitro Study of the Root Canal Configuration of Mandibular First Premolars in a Bengali Subpopulation Using Cone-Beam Computed Tomography.

Aim: This study aims to analyze the root canal configuration system of mandibular first premolars in the Bengali subpopulation using cone-beam computed tomography (CBCT).

Materials And Methods: Based on Vertucci's classification, the root canal morphology of 100 randomly selected mandibular first premolars in 56 males and 44 females from the Bengali subpopulation of West Bengal was assessed in vitro. The location of the apical foramen, lateral canal, C-shaped canal, types of canal orifice cross-sections, minor constriction diameter, tooth length, and root length were noted.

Modulating the Optical Properties of Cationic Surfactant Cetylpyridinium Chloride and Hydrazine Mediated Copper Nanoclusters.

This study investigates the modulations in the optical properties of cationic surfactant cetylpyridinium chloride (CPC) and hydrazine-mediated copper nanoclusters (CuNCs). By employing a bottom-up approach, we demonstrate the formation of blue-emitting CuNCs facilitated by CPC and hydrazine, where hydrazine acts both as a reducing and stabilizing agent. The optical properties of the CuNCs were systematically tuned by varying the chain length of the diamine, resulting in emissions ranging from blue to yellow.

Production, Delivery, and Regulatory Aspects for Application of Plant-Based Anti-microbial Peptides: a Comprehensive Review.

Antimicrobial peptides (AMPs) are small, positively charged biomolecules produced by various organisms such as animals, microbes, and plants. These AMPs play a significant role in defense mechanisms and protect from adverse conditions. The emerging problem of drug resistance in microbes poses a global health challenge in treating diseases.
