Reducing Toxic Constituents of Ginkgolic Acids Content and Improving Bioactive Flavonoids Content from Ginkgo Biloba Leaves by High Temperature Pretreatment Processing
High temperature pretreatment was developed in this article to remove the main toxic constituents of ginkgolic acids
(GAs) from Ginkgo biloba leaves (GBLs) and improve the bioactive flavonoids content by water extraction. To optimize
the effects of high temperature pretreatment process parameters on removing toxic GAs to the limited level and improving
content of bioactive flavonoids, a Box-Behnken design (BBD) combined with response surface methodology (RSM) was
also conducted. The results showed that the content of GAs could be reduced to 4.11 ppm and the highest content of flavonoids could reach 3.51 % under the optimized conditions of high temperature pretreatment process of 177 °C with water
extraction at 96 °C at a liquid-to-solid ratio of 56:1. The content of toxic GAs substantially decreased by 83.50% while the
content of bioactive flavonoids increased by 44.30% compared with the conventional water extraction method. Moreover,
the new process was more efficient, environmentally friendly and could get avoid of a subsequent multi-step process of
removing toxic GAs. The crude extracts were then purified by macroporous resin to obtain the 60% ethanol fraction. After
purification, the flavonoids content increased to 43.50% while the GAs were not detected. The main compounds of 60%
ethanol fraction were identified by UPLC-QTOF-MS/MS. Antioxidant activities including reducing powder, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, and OH· scavenging assays all showed that the 60% ethanol fraction was
better than the butylated hydroxytoluene (BHT) standard.

Assessment of Cyanide Concentrations in Cassava Peels obtained at different levels of Processing for Resource Reuse
Cassava processing is a year-round activity in Nigeria, especially in southern part and Ibadan city. The wastes generated by the various processing industries are enormous. Cassava peels are a major residue of processing to prepare various food products. The cassava peels have high concentration of cyanide which has toxic and polluting effects. It is therefore important that the peels are properly processed or pre-treated to reduce the cyanide content before using them as livestock feed which is a common practice among livestock rearers.
HIV Screening Scenarios and Targets to Achieve 90% Sero-Status Knowledge Over 2021-2025 in Morocco – Pioneer Use Case of the Goals HIV Testing Strategies Model in a Concentrated Epidemic
Morocco applied the Goals testing model, projecting alternative testing scale-up scenarios, varying coverage targets for 13 adult populations. The model was calibrated using program service delivery, spending and surveillance data (2015-2019), integrated bio-behavioural surveys, and national HIV estimates. It projects annual diagnoses by target group from undiagnosed prevalence and testing coverage, allowing for HIV-infected people self-selecting for testing, retesting and transitions between groups. Scenarios were
evaluated for knowledge status improvement and cost, focusing on 2023-2025.
Nightmare Case of Complex Neonatal Truncus Arteriosus
Neonatal management of severe quadricuspid truncal valve insufficiency is very challenging with high risk of postoperative mortality. Aortic valve reconstruction is the unique rescue and should be consider and previously planned in case of truncal valvuloplasty failure. Many extracardiac malformations can be associated with truncus arteriosus, therefore a cardiac and chest computed tomography scan must be performed before the elective surgical repair.
Effect of the Seasons on the Change of Morphological, Histo-Cytological and Hormonal Parameters of the Thyroid Gland in Cattle in Algeria
This study was carried out to study the peculiarities of the topography, the macrostructure and the analysis of the structural and functional organization patterns of the parenchyma of the thyroid gland of dairy cows (local breed from the Souk Ahras region, Algeria). A complex of macroscopic and histological techniques was used, as well as immunohistochemical staining of thyroid gland sections to identify localization characteristics of thyrocyte populations in the parenchyma.
Utilization of Red mud-Water/Soil Pollutant for Alternative Engineering Applications: A Critical Perspective Review
Environmental pollution and climate change continue to be a major cause for concern in the 21st century. Aluminum is the most abundant metal on the surface used in every walk of life. Red mud, a by-product produced during the extraction of Aluminium from Bauxite by Bayer’s Process, causes serious hazards for the human and ecological systems.
Formulation and Evaluation of Sustained Occular Delivery of Ciprofloxacin Hydrochloride
The aim of the present work was formulation and evaluation of in-situ gelling system of Ciprofloxacin Hydrochloride. The poor
bioavailability and therapeutic response exhibited by conventional ophthalmic solution due to rapid precorneal elimination of the drug
may be overcomed by the use of in-situ gel forming system that are installed as drop into the eye and undergo sol to gel transition in the
cul-de-sac.

Greater Trochanter Avulsion Associated with Posterior Hip Dislocation
Hip dislocation occurs when axial loading force is transmitted through intact femoral shaft to the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. However dislocation of the hip with associated fracture of the trochanter, neck or shaft of femur is uncommon in literature. We present the case of a 56 year old patient who fell from a height. Clinical and imaging [radiography, CT] examination revealed a comminuted greater trochanteric fracture associated with ipsilateral posterior hip dislocation.

The Relationship of Visuo-Motor Processing and Upright Balance in Acutely Concussed Athletes
Following a concussion, athletes display impairments in upright balance, as well as changes in visual acuity. Balance deficits arise as a result of sensory information integration impartments when sensory information processing is delayed or altered. Investigating the relationship between visual processing and balance following a concussion will help to better understand the underlying pathophysiologic mechanisms for balance deficits and why altered visuo-motor processing may be related to postural instability.
Ordered Growth of Anodic Aluminum Oxide in Galvanostatic and Galvanostatic-Potentiostatic Modes
The results are presented of obtaining anodic aluminum oxide with an ordered pore arrangement by employing two anodizing modes - galvanostatic mode and combined (galvanostatic + potentiostatic) mode, at high values of the current density and voltage. Use has been made of an oxalate electrolyte and a complex electrolyte comprising oxalic acid and phosphoric acid. Scanning electron microscopy has been used to investigate the surface morphology of the barrier and porous layers and to determine pore sizes and inter-pore distance.
