Oleogels (organogels) are systems resembling a solid substance based on the gelation of organic solvents (oil or non-polar liquid) through components of low molecular weight or oil-soluble polymers. Such compounds are organogelators that produce a thermoreversible three-dimensional gel network that captures liquid organic solvents. Oleogels based on natural oils are attracting more attention due to their numerous advantages, such as their unsaturated fatty acid contents, ease of preparation, and safety of use.

There is currently a growing interest in health-promoting foods. The beneficial effects of food on human health are actively promoted by health professionals and nutritionists. This growing awareness is influencing the increasing range of functional foods and the pursuit of more innovative solutions.

Hydrogels based on sodium alginate (SA) and partially neutralised poly(acrylic acid) were obtained by radical polymerisation. The hydrogels were cross-linked with N,N'-methylenebisacrylamide (MBA), simultaneously grafting the resulting polymer onto SA. The findings of the FTIR spectroscopy showed that all of the hydrogels were effectively synthesized and sodium alginate was chemically bonded with the poly(sodium acrylate) matrix.

Underactive bladder (UAB) is essentially an inability of the bladder to properly empty. UAB symptoms, when they co-occur with posterior fornix syndrome (PFS) symptoms (urge, frequency, nocturia, chronic pelvic pain), can be cured/improved, surgically by uterosacral ligament (USL) repair, non-surgically, by devices which give mechanical support of the USLs or strengthening pelvic muscle and ligaments with squatting-based exercises. The pathogenic pathway from weak USLs to UAB (and PFS) is that, when the muscles which externally open the posterior wall of the urethra contract against lax USLs, their contractile force weakens, and they cannot open the urethra adequately.

This paper explores a practical approach to pelvic floor health called the Skilling technique. Unlike the commonly recommended "squeezing upwards" method which teaches a woman to voluntarily squeeze upwards (a learnt technique), the Skilling method is entirely reflex: the squatting-based exercises on which it is based, strengthen the three reflex pelvic muscle forces which pull against the suspensory ligaments pubourethral ligament (PUL) and uterosacral ligament (USL) to: close the urethra during effort (control of stress incontinence), open the urethra during micturition, and stretch the vagina in opposite directions to control inappropriate activation of the micturition reflex [overactive bladder (OAB)]. The strengthened ligaments better support the pelvic visceral plexuses (VPs), which unsupported, can fire off impulses which the brain interprets as "chronic pelvic pain".
