Plasmodium parasites, which cause malaria, continue to pose a serious threat to global health, necessitating the continuous search for novel antimalarial agents. Entada africana is a plant known for its ethnomedicinal uses in treating various ailments associated with inflammation including malaria. Due to its reported antiplasmodial potentials, we studied the effect of the methanol bark extract of the plant. HPLC chromatogram of the methanol bark extract showed the presence of eight phyto-compounds namely coumaric acid, gallic acid, catechin, ferulic acid, quercetin, apigenin, rutin, and kaemferol. Thus, the study aimed at evaluating the antiplasmodial potential of methanol bark extract of Entada africana (MBEEA) through heme polymerase inhibition via in silico approaches. The in silico studies showed favourable binding affinities and stable interactions with heme polymerase, with rutin (-9.9 kcal/mol), apigenin (-8.0 kcal/mol) and catechin (-7.8 kcal/mol) having higher binding affinities compared to the standard drug, chloroquine (-6.7 kcal/mol).

The determination of the postmortem interval (PMI) towards assisting in medicolegal investigations is a frequent requirement in any developed jurisdiction. Each of the latter has prevailing peculiarities, especially with many operating variables that include seasonal changes. There is a dearth of information about the decompositional pattern and progress of cadavers deposited on the ground in Nebraska, a jurisdiction lying within the Central Great Plains of North America. The present study, using an experimental pig was designed to consider the entomological peculiarities within a geographical area exhibiting taphonomic characteristics, and during a defined season.

The present paper contains experimental analysis of the spatiotemporal structure of atmospheric pressure dielectric barrier discharge (DBD) in a packet-pulse excitation mode widely used as an effective tool for plasma modification of various media. The motivation is the need to optimize the conditions for DBD plasma obtaining with a homogeneous diffuse structure. It is shown that for a discharge gap of the millimeter range (1–3 mm) in atmospheric air, under certain conditions, a number of new plasma phenomena are possible - the effects of an increase in the density (total number) of filamentary discharges over time, both unchanged and with a decrease in the area of the filaments, as well as the formation of complex space-time structures. An interpretation of this phenomenon is proposed. Homogeneous diffuse discharges are obtained in a standard electrode configuration with a single dielectric

The aim of controlling/regulating cellular processes by surface patterning of biomaterials is a crucial concept in emerging research fields, where the precise fabrication of micro-nano surface topographies is required at manufacturing scales to meet consumer demand. Photolithography is typically employed for surface patterning; however, the high cost, process complexity, and lack of environmentally friendly and sustainable methodologies represent steep barriers for many researchers. Soft lithographic methods have been utilised extensively as a potential alternative for traditional photolithography, yet a photolithographic step is still required for initial template fabrication. Here, we demonstrate the use of repurposed optical consumer items such as DVDs, diffraction glasses, and gratings that would otherwise be thrown away after their useful lives, being used here as a sustainable approach as templates for the formation of complex nano-patterns. By replicating these templates in polydimethylsiloxane (PDMS) and polylactic acid (PLA), we show the varied interactions of human aortic smooth muscle cells (HAoSMC) to these surfaces. Notably, it was demonstrated that, in comparison to nonpatterned substrates, HAoSMC interaction (adhesion, spreading, and viability) was higher on DVD patterned surfaces compared to diffraction glass and grating patterned surfaces according to the results from cell metabolic activity (MTT and Alamar Blue), and proliferation (total DNA) assays. We demonstrate that a simple, reusable, inexpensive, yet robust technology could be a powerful tool in improving our understanding of cell-surface interactions and for the potential development of medical devices with micro- and nanoscale low or high adhesion features

Intravascular large B-cell lymphoma (IVBCL) is a rare but aggressive form of non-Hodgkin lymphoma. It is characterized by the malignant proliferation of lymphocytic tumor cells in the lumens of capillaries, small arterioles, and post-capillary venules. There exists two clinical variants: the Asian variant and the Western variant. The former is associated with neurologic and dermatologic signs and symptoms, whereas the latter often presents with splenomegaly, jaundice, and hemophagocytes. Lymphadenopathy is uncommon, and patients typically have nonspecific symptom

Gestational diabetes mellitus (GDM) is associated with an increased maternal and fetal risk of complications. Other than lifestyle modifications and diet, little prevention can be done towards this maternal complication. Through a preclinical approach and a retrospective clinical trial, we investigated the effects of maternal supplementation with a nutraceutical composition based on resveratrol (RSV) and alpha-lipoic acid (ALA) on insulin resistance and GDM status

The main aim of this project is to formulate and evaluate Clindamycin peel-off gel face mask against Acne vulgaris. Peel off gel mask of Clindamycin phosphate was formulated using different excipients like Triethanolamine, Carbopol, Polyvinyl Alcohol, Glycerine, Xanthan gum, and Benzyl alcohol. Formulation of different composition of polymer was formulated and their pH, extrudability, homogeneity, spreadability, viscosity, washability and other parameters like drug content, permeability and drug release were evaluated. The result showed that the concentration of PVA and Carbopol which are the main polymers used in the formulations had effect on the drug content, drug release, permeability, spreadability and other parameters. The peel off mask prepared by using different concentration of these two polymers showed satisfactory result in all the evaluated parameters.

Candida albicans is an opportunistic agent that can produce systemic infections in immunosuppressed patients. By varying its cell wall antigens this fungus can evade the immunological response by varying its cell wall antigens. On the other hand, Larrea divaricata Cav. (Jarilla) is a widely spread plant in America and it is used in folk medicine to treat several pathologies. It has been shown that antibodies against Jarilla proteins of crude extract (JPCE) cross-react with proteins of other microorganisms such as Gram-negative bacteria.

Eczema herpeticum (EH) is a skin infection caused by the herpes simplex virus (HSV) that occurs in individuals with atopic dermatitis. It is characterized by the sudden appearance of vesicles and erosions with crusts over areas affected by eczema. EH can range from mild and self-limiting in healthy adults to life-threatening in children, infants, and immunocompromised patients. Early treatment with antiviral therapy is crucial in preventing complications and mortality. EH is primarily caused by a superinfection of HSV, usually HSV-1, in individuals with atopic dermatitis. Reactivation of HSV is more common than primary infection. Patients with atopic dermatitis are more susceptible to skin infections due to impaired skin barrier function and immune dysregulation. Disseminated cutaneous HSV infection can also occur in individuals with other forms of dermatitis, known as Kaposi varicelliform eruption (KVE)

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
