A systematic investigation of the relationship between properties of bulk foam and foam in porous media.

Bulk foam analysis (static test) is simple and fast, which makes it a cost-effective method for screening and ranking hundreds of surfactants being considered for foam applications. Coreflood tests (dynamic test) can also be used, but it is quite laborious and costly. However, previous reports show that ranking based on static tests sometimes differs from ranking based on dynamic tests.

Technological trends in nanosilica synthesis and utilization in advanced treatment of water and wastewater.

Water and wastewater treatment applications stand to benefit immensely from the design and development of new materials based on silica nanoparticles and their derivatives. Nanosilica possesses unique properties, including low toxicity, chemical inertness, and excellent biocompatibility, and can be developed from a variety of sustainable precursor materials. Herein, we provide an account of the recent advances in the synthesis and utilization of nanosilica for wastewater treatment.

Environmental risks and toxicity of surfactants: overview of analysis, assessment, and remediation techniques.

This work comprehensively reviewed the toxicity and risks of various surfactants and their degraded products in the environmental matrices, various analytical procedures, and remediation methods for these surfactants. The findings revealed that the elevated concentration of surfactants and their degraded products disrupt microbial dynamics and their important biogeochemical processes, hinder plant-surviving processes and their ecological niche, and retard the human organic and systemic functionalities. The enormous adverse effects of surfactants on health and the environment necessitate the need to develop, select, and advance the various analytical and assessment techniques to achieve effective identification and quantification of several surfactants in different environmental matrices.

Methods: a comparative cross-sectional study of adult patients aged 40 years and above who had pressure was measured with Goldman's applanation tonometer pre-operatively and 1 day, 1 week, 1 month as well as 3 month post-operative periods and recorded.

Choroidal detachment with exudative retinal detachment following Ahmed valve implantation in Sturge-Weber syndrome.

Ahmed glaucoma valve implant appears to be a relatively useful drainage device in eyes with glaucoma secondary to Sturge-Weber syndrome (SWS). However, early postoperative choroidal and exudative retinal detachment may occur from a rapid expansion of the choroidal hemangioma with effusion of fluid into the suprachoroidal and subretinal spaces. We report the case of a ten-year-old boy who had SWS with choroidal haemangioma and secondary glaucoma.

Burden of family caregivers of ophthalmic patients in a university teaching hospital in south-west Nigeria.

Background: The family provides support in the care of their ill members and suffers some burden during caregiving. This study assessed the burden of family caregivers and associated factors in an ophthalmic clinic situated in a university teaching hospital in southwest Nigeria.

Methods: This was a descriptive cross-sectional study where consenting family caregivers of ophthalmic patients completed a semi-structured questionnaire containing information on their socio-demographic characteristics and caregiving burden using the Zarit burden interview.

Molecular dynamics and combined docking studies for the identification of Zaire ebola virus inhibitors.

Ebola virus (EBOV) is a lethal human pathogen with a risk of global spread of its zoonotic infections, and specifically has the highest fatality rate amongst other species. There is a need for continuous effort towards having therapies, as a single licensed treatment to neutralize the EBOV is yet to come into reality. This present study virtually screened the MCULE database containing almost 36 million compounds against the structure of a Zaire Ebola viral protein (VP) 35 and a consensus scoring of both MCULE and CLCDDW docking programs remarked five compounds as potential hits.

Relationship between Refraction, Anthropometrics, and Educational Status in a Nigerian Young Adult Population.

Purpose: The study aimed at determining the relationship between refraction and anthropometric measurements and the relationship between the level of education and refractive status in a Nigerian young adult population.

Materials And Methods: Healthy volunteers from the students and staff of a teaching hospital in South-Western Nigeria were studied. Demographic profiles including participants' highest educational status, parental educational level, and the age at first formal school enrollment were documented.

New onset neuromyelitis optica in a young Nigerian woman with possible antiphospholipid syndrome: a case report.

Introduction: Devic's neuromyelitis optica is an inflammatory demyelinating disease that targets the optic nerves and spinal cord. It has a worldwide distribution and distinctive features that distinguish it from multiple sclerosis. There has been no previous report of neuromyelitis optica from our practice environment, and we are not aware of any case associated with antiphospholipid syndrome in an African person.
