Article Abstract
Unlabelled: The prolactinomas are the most common functioning pituitary tumors. The hyperprolactinemia is associated with anovulation and infertility.
Objectives: a) describe the relationship between hyperprolactinemia and fertility, b) review the results of the use of dopamine agonists during pregnancy and embryo-fetal development and c) review the therapeutic management in micro and macroprolactinomas during pregnancy.
Content: Medical therapy with dopamine agonists is the best treatment for prolactinomas of any size or invasiveness and restores ovulatory cycles in 80-90 % of patients. Cabergoline currently suggested rather than bromocriptine due to their excellent tolerability and long half-life. In general, it is recommended that fetal exposure to all drugs be limited to as short a period as possible. In the absence of menstrual period, the drug should be discontinued and confirm pregnancy.
Conclusion: Both, bromocriptine and cabergoline, showed no evidence of obstetric and neonatal complications; however, experience with bromocriptine is higher. The patients with macroprolactinomas should be monitored clinically and evaluate the symptoms related to increased tumor size. If growth in the adenoma is suspected, nuclear magnetic resonance and neuro-ophthalmologic examination should be performed. In microprolactinomas the ophthalmologic examination is no formal indication. There is evidence that breastfeeding no increased risk for tumor growth.

Parkinson's disease (PD) is a chronic, progressive neurological disorder primarily affecting motor control, clinically characterized by resting tremor, bradykinesia, rigidity, and other symptoms that significantly diminish the quality of life. Currently, available treatments only alleviate symptoms without halting or delaying disease progression. There is a significant association between PD and type 2 diabetes mellitus (T2DM), possibly due to shared pathological mechanisms such as insulin resistance, chronic inflammation, and mitochondrial dysfunction.

Introduction: Breast cancer, a formidable global health challenge for women, necessitates innovative therapeutic strategies with enhanced efficacy and minimal side effects. Aripiprazole (ARI), a widely used schizophrenia medication, exhibits promising potential in the treatment of breast cancer. As cancer therapy evolves towards a combination approach, multimodal nano-based delivery systems, such as ARI-loaded niosomes (NIOs) combined with Chitosan-Au nanoparticles for chemo-photothermal therapy, show promise over traditional chemotherapy alone by enhancing targeted efficacy and minimizing side effects.

The ability to choose between options that differ in their risks and rewards depends on brain regions within the mesocorticolimbic circuit and regulation of their activity by neurotransmitter systems. Dopamine neurotransmission in particular plays a critical role in modulating such risk-taking behavior; however, the contribution of other major modulatory neurotransmitters, such as acetylcholine, is not as well-defined, especially for decision making in which the risk associated with more rewarding outcomes involves adverse consequences. Consequently, the goal of the current experiments was to examine how cholinergic signaling influences decision making involving risk of explicit punishment.

Background: Giant prolactinoma (size > 4 cm) is a rare condition and accounts for less than 1% of pituitary adenomas. In even rarer cases, these lesions may involve craniocervical structures requiring surgical intervention. The present case is the largest reported giant prolactinoma (99 × 72 × 57 mm).

The thalamic reticular nucleus (TRN) is a thin shell of gap junction coupled GABAergic inhibitory neurons that regulate afferent sensory relay of the thalamus. The TRN receives dopaminergic innervation from the midbrain, and it is known to express high concentrations of D1 and D4 receptors. Although dopaminergic modulation of presynaptic inputs to TRN has been described, the direct effect of dopamine on TRN neurons and its electrical synapses is largely unknown.
