On the Self-Organization of Dielectric Barrier Discharges
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
Haosmc Growth on Various Sustainable Nano/Micropatterned Surface Topographies Utilising Reusable Surface Templatin
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, an Updated Review
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
The Efficiency and Safety of a Resveratrol and Alpha Lipoic Acid Combination in the Prevention of Gestational Diabetes Related Complications: A Retrospective Clinical Trial
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

Formulation and Evaluation of Clindamycin Peel-Off Gel Face Mask against Acne Vulgaris
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.

Antibodies Anti-Proteins of Larrea Divaricata Cav. Present Opsonic Capacity on Candida Albicans Atcc 36801 and Neutralize its Cytotoxic and Immunoevasive Properties
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.
Spinal Muscular Atrophy-Type1, Unraveling the tapestry from highly inbred region of North India
spinal muscular atrophy is an autosomal recessive disorder characterized by degeneration of alpha motor in anterior horn
cells of brain and spinal cord, which results in muscular atrophy, hypotonia, fasciculations, areflexia, paralysis and even
death in most severe cases. The underlying cause of this disease is biallelic loss of survival motor neuron 1 (SMN1) gene. Depending upon the clinical features & patient's age, SMA is classified into different distinctive sub types
Comparison of Physicochemical and Binding Properties of Novicel™ Microcrystalline Cellulose and Avicel® PH 101 in Direct Compression of Ascorbic Acid Tablets

as tablets. In this study, the microcrystalline cellulose (Novicel™) obtained from sugarcane bagasse (a waste material from
sugarcane factories) was compared with Avicel PH 101 (a commercially available MCC) for its physicochemical characteristics
and potential as a dry binder in direct compression of ascorbic acid tablets.
Recurrent Ophthalmic Eczema Herpeticum with Hyper Immunoglobulin E Syndrome in A 4 Years-Old Boy
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)
Radiographic Outcomes of FDBA Block Graft for Maxillary Ridge Augmentation: A Case Report
The primary donor sites for collecting bone in the oral cavity to replace missing ridges are the mandibular symphysis or ramus. Although successful, these bone transplants can nevertheless raise a number of issues, including donor site morbidity,
nerve paresthesia, the devitalization of native teeth, and postoperative sequelae . Allogeneic block grafts were developed to
address these concerns and a lack of autogenous intraoral bone available for grafting

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films
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.
