HIV-1 viral protein R (Vpr) and its interactions with host cell.

Vpr’s Toolkit: Key Functions in HIV-1 Infection Cell Cycle Sabotage: Arresting G2/M for Viral Gain Vpr’s most infamous role is inducing G2/M cell cycle arrest, creating an optimal environment for viral replication. By recruiting the CRL4-DCAF1 E3 ubiquitin ligase complex, Read more…


Strathclyde minor groove binders (S-MGBs) with activity against Acanthamoeba castellanii

Two Faces of Danger: Trophozoites vs. Cysts Acanthamoeba exists in two forms: Trophozoites: Active, feeding cells that invade tissues. Cysts: Dormant, armored structures resistant to disinfectants and immune attacks . Encystation, triggered by stress like drug exposure, allows the amoeba Read more…


Prevalence and management practices of malaria in a rural community of Ebonyi state, southeast Nigeria

Prevention: Bed Nets and Behavior Change Insecticide-Treated Nets (ITNs): Over 1.7 million ITNs have been distributed in Ebonyi since 2015, supported by The Carter Center and USAID . However, only 19% of households in Ezza North LGA consistently use them Read more…


The Research Progress of 1,25(OH)2D3 Effects on Cervical Cancer

The Dual Mechanisms of 1,25(OH)2D3 1,25(OH)2D3 exerts its effects through genomic and non-genomic pathways: Genomic Action: Binds to the vitamin D receptor (VDR), regulating genes involved in cell differentiation, apoptosis, and immune response . Non-Genomic Action: Rapidly activates signaling cascades Read more…


A Versatile Class of 1,4,4-Trisubstituted Piperidines Block Coronavirus Replication In Vitro

The Piperidine Scaffold: A Drug Designer’s Playground Piperidines, six-membered rings containing nitrogen, are a cornerstone of medicinal chemistry. Their versatility allows scientists to tweak substituents for optimal bioactivity. Recent advances include: Synthetic Innovations: Metal-free photocatalysis and Ugi multicomponent reactions enable Read more…


Dietary seaweed (Saccharina latissima) supplementation in pigs induces localized immunomodulatory effects and minor gut microbiota changes during intestinal helminth infection

Seaweed’s Nutritional Arsenal Brown seaweeds like Saccharina latissima contain: Polysaccharides (laminarin, fucoidan): Prebiotics that feed beneficial gut bacteria. Fatty acids: Anti-inflammatory and antimicrobial agents. Minerals: Iodine, zinc, and iron, crucial for immune function. Studies show these compounds enhance intestinal barrier Read more…


Promising use of immune cell‐derived exosomes in the treatment of SARS‐CoV‐2 infections

Neutralizing the Virus SARS-CoV-2 infects cells by binding its spike protein to ACE2 receptors. Researchers have engineered exosomes to outcompete the virus: ACE2-Decoy Exosomes: Circulating exosomes expressing ACE2 capture viral particles, preventing cellular entry . Spike-Protein Display: Lung-derived exosomes conjugated Read more…


Trend of drug clinical trials in mainland China from 2009 to 2020

Growth Trends: Accelerating Volumes and Diversification China’s clinical trial landscape expanded dramatically during this period. Evidence from national databases and peer-reviewed studies reveals: Total Trials Surge: From 2009 to 2020, the annual number of trials grew by over 300%, driven Read more…


The immune response to herpes simplex virus: Comparison of the specificity and relative titers of serum antibodies directed against viral polypeptides following primary herpes simplex virus type 1 infections

Antibodies: The First Line of Defense After primary HSV-1 infection, the immune system produces antibodies targeting viral proteins. Key findings include: Primary vs. Recurrent Infections: During primary infection, antibodies target a broader range of viral polypeptides, including envelope glycoproteins (e.g., Read more…


In-Vivo Anti-Malarial Activity of 80% Methanol Leaf Extract of Croton Dichogamus Pax and Ehretia Cymosa Thonn in Plasmodium Berghei Infected Mice

Parasitemia Suppression Ehretia cymosa: At 400 mg/kg, the extract suppressed parasite levels by 66.28%—comparable to chloroquine, the standard drug. Even lower doses (200 and 100 mg/kg) achieved 63.44% and 63.14% suppression, classified as “very good” activity . Croton dichogamus: The Read more…
