Objectives: To describe a fuzzy logic controller that adjust alfentanil infusion during surgery based on changes in mean arterial pressure (MAP) and heart rate (HR).
Material And Methods: We designed a fuzzy logic controller using if ... then ... conditions written in C language, to be executed by a 486 PC with a 66 Mhz CPU. The controller was used with eight ASA I-II patients undergoing gynecological surgery under anesthesia with propofol, alfentanil and ventilated with oxygen/air. MAP and HR were input every three minutes, after which the controller generated an infusion based on those figures. We performed a statistical study of alfentanil consumption time until extubation and time of hemodynamic stability. Relative error of MAP was calculated.
Results: The controller was used for a total of 373 min with the eight patients. MAP was 15% below the desired level for 2.14% (18 min) of that time and was 15% over the desired level for 5.6% (21 min) of the time. MAP held steady within the range of stability for the remaining 92.26% (334 min) of the time the controller was used. The relative error of MAP was 7.8 +/- 1.5%. Mean time until extubation was 7 min and 2 s.
Conclusions: We believe the controller can be used to automate taks executed by experts. The controller was useful for stabilizing HR and MAP.

Background: Myelomeningocele (MMC) is the most common type of congenital spinal malformation, typically requiring surgical intervention. While prenatal repair is increasingly favored, postnatal repair remains the standard in many settings. This study aims to evaluate the antibiotics prescribed to neonates with MMC and their correlation with central nervous system (CNS) infection rates following postnatal surgical repair.

Atopic dermatitis (AD) is a chronic inflammatory skin condition characterized by dry skin, severe itching, redness, and inflammation. Its complex etiology, involving genetic, immunological, and environmental factors, necessitates innovative therapeutic approaches. This study investigates nanostructured lipid carriers (NLCs) formulated with traditional fermented coconut (Cocos nucifera L.

Aminopolyphosphonates (APPs) are widely used as chelating agents, and their increasing release into the environment has raised concerns due to their transformation into aminomethylphosphonic acid (AMPA) and glyphosate, compounds of controversial environmental impact. This transformation highlights the urgent need for detailed studies under controlled conditions. Despite the availability of various methods for quantifying individual aminopolyphosphonates and aminomonophosphonates, a green, low-cost approach for the simultaneous quantification of APPs and their transformation products in laboratory experiments has been lacking.

This study aimed to investigate the digestion and absorption properties of caprine milk serum proteins in comparison to human and bovine species by using rat pups to mimic preterm infants. The results indicate that caprine lactoferrin (LTF) had a shorter retention time in the intestine and released a greater number of fragments, resembling human milk LTF more closely. In contrast, caprine immunoglobulins (Igs) were similar to bovine Igs and both exhibited a longer retention time in the intestine.

Introduction: To report the progress of the human living uterus transplant research project in Singapore.
Material And Methods: The uterus transplant research project began in 2012 with a collaboration between the Swedish and Singapore teams. Ethics approval was obtained from the SingHealth Centralised Institutional Review Board, the SingHealth Transplant and the Singapore General Hospital Biomedical Ethics Committee to perform 5 uterus transplant procedures in a collaborative multi-site research study at the Singapore General Hospital.
