The results showed that the electromembrane extraction method was only able to extract the unbound fraction of phenytoin from plasma samples. The method was validated over a concentration range of 0.03-4μg/mL. The inter and intra-assay precisions were less than 6.7%. The phenytoin protein binding was also determined to be in agreement with the literature data and confirms the validity of this method.
This sensitive and quick EME approach for determining the free concentration of a phenytoin, can be a good alternative to classic methods for therapeutic drug monitoring and pharmacokinetic studies.

Systemic complications alongside coagulopathy, and ARDS account for the majority of COVID-19 mortalities. The pathogenesis of the disease can be explained by two theories of direct viral cytopathy and systemic inflammatory cascade of events. ACE-2 is shown to be the cellular host receptor for SARS-CoV-2. It might be the key to explain the pathogenesis of systemic complications with a focus on the direct viral cytopathic hypothesis. Different medications tend to show up in many in vitro drug screens. However, more trials are needed to translate their application into in vivo efficacy.
The amphibian, non-vascular, gametophyte-dominant, bio-indicator class, bryophytes; with their wide ranges of habitat have attained importance due to their promising medicinal attributions and therapeutic role; mostly aided by presence of aromatic bibenzyl and bisbybenzyl class of compounds. Bibenzyls are steroidal ethane derivatives, resembling the structural moiety of bioactive dihydro-stilbenoids or iso-quinoline alkaloids. These stress triggered secondary metabolites are the by-products of the flavonoid biosynthetic pathway. Different classes of bryophytes (Bryophyta, Marchantiophyta and Anthocerotophyta) possess different subtypes of bibenzyls and dimeric bisbibenzyls. Among the liverwort, hornwort and mosses, former one is mostly enriched with bibenzyl type constituents as per the extensive study conducted for phytochemical deposit. Considering macrocyclic and acyclic group of bibenzyls and bisbybenzyls, generally marchantin type compounds are reported vividly for significant biological activity that t.
This review encompasses prospective biological application of botanical reservoir of this primarily ignored, primeval land plant group where recent technical advances has paved the way for qualitative and quantitative isolation and estimation of novel compounds as well as marker components to study their impact on environment, as bio-control agents and as key leads in future drug designing.

Many types of oncolytic viruses (OVs) were enrolled in clinical trials. Recently, an OV named Talimogene laherparepvec approved for the treatment of melanoma. This achievement highlighted the clinical application of OVs. Scientists focus on using these anticancer agents in combination with the current or/and new anticancer chemotherapeutics. They aim to increase the oncolytic effect of a new approach for the treatment of cancer cells.
The present study aimed to assess the anticancer impacts of ReoT3D, irinotecan (CPT-11), and napabucasin (BBI608) against murine colorectal cancer cells (CT26). They are assessed alone and in combination with each other.
Here, oncolytic reovirus was propagated and titrated. Then MTT assay was carried out to assess the toxicity of this OV and chemotherapeutics effect on CT26 cells. The anticancer effects of ReoT3D, CPT-11, and BBI608, alone and simultaneously, on CT26 cell line, were assessed by the induction of apoptosis, cell cycle arrest, colony-forming, migration, and real-time PCR experiments.
Alone treatment with ReoT3D, CPT-11, and BBI608 led to effectively inducing of apoptosis, cell cycle arrest, and apoptotic genes expression level and significantly reduce of colony-forming, migration, and anti-apoptotic genes expression rate. Importantly, the maximum anticancer effect against CT26 cell line was seen upon combination ReoT3D, CPT-11, and BBI608 treatment.
The present study highlights that combination of ReoT3D, CPT-11, and BBI560 showed synergistic anticancer activity against CT26 cell line. This modality might be considered as a new approach against colorectal cancer (CRC) in the in vivo and clinical trial investigations.

Recently, photothermal therapy has been extensively applied to cancer treatment due to heat-induced tumor ablation. Herein, we fabricated albumin nanoparticles (HSA-NPs) loaded with paclitaxel (PTX), indocyanine green (ICG; a hyperthermal agent) and hyaluronidase (HAase) that breaks down hyaluronan, a major component of the extracellular matrix (ECM) in tumors. Synthesis was based on a slightly modified nanoparticle albumin-bound (Nab™) technique. The prepared nanoparticles (PTX/ICG/HAase-HSA-NPs) had a spherical shape with an average size of ~ 110 nm and a zeta potential of ~ -30.4 mV. They displayed good colloidal stability and typical patterns of ICG, HSA and HAase in UV-VIS-NIR and circular dichroism spectroscopic analysis. this website PTX/ICG/HAase-HSA-NPs were found to have excellent hyperthermal effects in response to near-infrared laser irradiation (808 nm) (up to > 50 °C over 4 min). The hyperthermia conducted by PTX/ICG/HAase-HSA-NPs resulted in significant cytotoxicity to pancreatic AsPC-1 cells at both severe (> 50 °C) and mild (41-42 °C) hyperthermal states in conjunction with the inherent cytotoxic activity of paclitaxel. Furthermore, the confocal images of AsPC-1 cell spheroids proved PTX/ICG/HAase-HSA-NPs were able to permeate deeply into the three-dimensional tumor tissue mimicry structure. Most of all, PTX/ICG/HAase-HSA-NPs maintained all these physicochemical and anti-cancer properties irrespective of the amount of embedded HAase (1-5 mg). Our results demonstrated that PTX/ICG/HAase-HSA-NPs are a promising hyperthermal/chemotherapeutic anticancer agent.
