The paper is based on the results of a CT study of 71 women with normal pelvic dimensions without pelvic bone or pelvic organ pathology who underwent the study in 2022-2023. All subjects consented to the study, which was performed according to the indications. The CT study consisted of determining the width, height, and thickness of the pubic symphysis in 3D reconstruction mode.

Carcinoid of the thin bowel is difficult to diagnose pathology. Complications diagnosticians with that doctors clash on ambulatory and hospital the stages, including at offtype clinical presentation of disease, result in late recognition of carcinoid and belated operative intervention. In taken apart case a diagnosis was set at pathomorphologic research.

Material And Methods: The study involved 316 patients with various etiologies of the CDLD, with the underwent both liver biopsy, the UEL, and evaluation of fibrosis (F) according to the Metavir classification.
Results: The maximum diagnostic accuracy of the UEL was obtained in determining of the 4-th stage of fibrosis according to the Metavir.
The capacity of a specially designed neural network for familiarity recognition and recollection has been compared. The recognition is based on calculating some quantity interpreted as the familiarity of a pattern. The familiarity is calculated using a modified Hopfield energy function in which the value of the inner sum is replaced by the sign of this value.

We consider a neural network model of age-related cognitive changes in aging brain based on Hopfield network with a sigmoid function of neuron activation. Age is included in the activation function as a parameter in the form of exponential rate denominator, which makes it possible to take into account the weakening of interneuronal links really observed in the aging brain. Analysis of properties of the Lyapunov function associated with the network shows that, with increasing parameter of age, its relief becomes smoother and the number of local minima (network attractors) decreases.

The results of neuropsychological and neurobiological studies on memory blocking have been reviewed, and basic problems whose solution could contribute to the comprehension of this phenomenon have been formulated. One of such questions is the existence of a paradoxical discrepancy between the subjective assurance that a pattern is familiar and the impossibility to recollect it fully.

Inobservance of ecologically tolerable levels degrades ecological status of the ecosystems manifested as deviation from normal saprobic indices of phytoplankton, zooplankton, and periphyton as well as biotic indices of zoobenthos. The basins were compared by the calculated ETL values for over 40 physicochemical indices.

A brief history of optimization approach in modern evolutionary ecology is given and author's own results concerning life history evolution are considered in more details. The problem of evolutionary optimization is formulated in terms of mathematical theory of optimal control as a problem of optimal sharing of organism's resources between growth, reproduction, repair, and maintenance. The Malthusian parameter is used as optimality criterion.

Network models of neural, genetic, immune and endocrine regulation are considered and a conception of organism as an integrative network system is introduced. A new approach to the problem of organism state control, called associative control, is proposed and its possible medical applications, in particular, in psychotherapy, psychoanalysis and alternative medicines are discussed.
