A comparative study on the clinical profile of COVID-related and non-COVID-related acute invasive fungal rhino sinusitis.

Purpose: To compare the clinical profile of COVID-related and non-COVID-related rhino-orbito-cerebral invasive fungal disease.

Methods: We have compared the comorbidities, clinical features, course of the disease and outcome between COVID-related and non-COVID-related acute invasive fungal rhinosinusitis (AIFRS) of the rhino-orbito-cerebral form.

Results: HbA1c and blood sugar at the time of admission were significantly higher in the non-COVID group (P < 0.

Potential targetability of multi-walled carbon nanotube loaded with silver nanoparticles photosynthesized from Ocimum tenuiflorum (tulsi extract) in fertility diagnosis.

Nanocarrier mediated targeted delivery and biosensing in reproductive health care is a major exploratory domain. This work demonstrates the loading of silver nanoparticle (AgNP) inside the multiwalled carbon nanotube (MWCNT) and their targetability to the intracellular part of the sperm cell for its further application in biosensing based infertility diagnosis. Ocimum tenuiflorum (tulsi extract) mediated photosynthesized AgNP exhibited spherical shape, 5-40 nm size and surface plasmonic resonance at 430 nm.

An emerging interface between life science and nanotechnology: present status and prospects of reproductive healthcare aided by nano-biotechnology.

Among the various applications of nano-biotechnology, healthcare is considered one of the most significant domains. For that possibility to synthesize various kind of nanoparticles (NPs) and the ever-increasing ability to control their size as well as structure, to improve surface characteristics and binding NPs with other desired curing agents has played an important role. In this paper, a brief sketch of various kinds of nanomaterials and their biomedical applications is given.

Smart RISUG: a potential new contraceptive and its magnetic field-mediated sperm interaction.

The rationale and technique underlying a novel concept of noninvasive fertility control by a new Cuproferrogel contraceptive drug, iron oxide-copper-styrene maleic anhydride-dimethyl sulphoxide (Fe3O4-Cu-SMA-DMSO) composite named 'Smart RISUG' (smart reversible inhibition of sperm under guidance) in presence of pulsed magnetic field (PMF; 1 mT to 800 mT) is explained. It was synthesized by dispersing iron oxide particles and copper particles into SMA-DMSO (male contraceptive RISUG) and characterized for particle distribution, particle size measurement and transmittance peaks, etc. Interaction of the RISUG particles as well as Smart RISUG particles with Albino rat sperm cell was studied in presence as well as absence of PMF.
