Inflammation and oxidative stress processes in induced precocious puberty in rats.

This study aimed to assess the influence of different types of blue light sources on male and female rats' puberty onset, the morphologic-induced alterations in reproductive organs tissues, the impact on inflammation and oxidative stress markers, anxiety levels, and mathematical modeling for tissue data interpretation. Four groups of sixteen rats each (8 females and 8 males/group) were investigated: three groups were exposed to blue light from mobile phones (MP), computer screens (PC), or LED lamps (LED) versus the control group (CTRL). The rats in the CTRL group had no exposure while the other groups were exposed for 30 days to the blue light of MP, PC, and LED for 16 h per day.

Short histological kaleidoscope - recent findings in histology. Part IV.

The paper provides an overview of the current understanding of different cells and structures' biology [e.g., blood-retinal barrier, Bruch membrane, Clara (club) cells, brush cells and tuft cells, Merkel cells, Hofbauer cells, cytokeratins], including their origin, structure, function, and role in disease pathogenesis, and of the latest findings in the medical literature concerning the paracortex of the lymph nodes.

The effects of radiofrequency electromagnetic radiation emitted by mobile phones on rat parotid gland histology - an experimental study.

Objective: The advancement of telecommunication technology and devices promptly transformed mobile phones into indispensable objects in our day-to-day lives, but their biological effects remain unclear. Therefore, this study aimed to investigate the potential histopathological changes induced by mobile phone radiation in the parotid gland and the nearby tissues.

Materials And Methods: Thirty female Rattus Norvegicus rats were divided into three groups: group 1 (exposed for 30 days), group 2 (exposed for 60 days), and control group (non-exposed).

Electrospun Membranes Based on Quaternized Polysulfones: Rheological Properties-Electrospinning Mechanisms Relationship.

Composite membranes based on a polymer mixture solution of quaternized polysulfone (PSFQ), cellulose acetate phthalate (CAP), and polyvinylidene fluoride (PVDF) for biomedical applications were successfully obtained through the electrospinning technique. To ensure the polysulfone membranes' functionality in targeted applications, the selection of electrospinning conditions was essential. Moreover, understanding the geometric characteristics and morphology of fibrous membranes is crucial in designing them to meet the performance standards necessary for future biomedical applications.

The Effect of Polyphenols Extract in Induced Endometriosis in Rats.

Endometriosis is a common gynecological condition with a complex physio-pathological background. This study aimed to assess the role of leaf extract (RiDE) as a potential therapeutic agent in reducing the size of the endometriotic lesions and modulate the plasma expression of MMP-2, MMP-9, and TGF-β1. The endometriotic lesions were induced in a rat model by the autologous transplant of endometrium.
