Background: Novel antipsychotics are characterized by multitarget profile of action, affecting among others, dopamine and serotonin receptors. In a series of experiments, we designed, synthesized and examined two new isoquinoline-sulfonamide analogs of the modern multitarget antipsychotics aripiprazole and brexpiprazole, compounds PZ-1262 and PZ-1264. We hypothesized that the 4-isoquinolinesulfonamide moiety, derived from the structure of 5-HT receptor antagonists, would provide compounds with enhanced activity at 5-HT receptors, along with partial agonistic activity at 5-HT and D receptors.

This study aimed to extend the body of preclinical research on two naphthyl-derived methylpiperazine-1,3,5-triazine analogues with thioether () or Se-ether () linkers, the newly described compounds having high affinity and selectivity for 5-HT receptors and drug-like parameters in vitro. Thus, crystallography-supported deeper insight into their chemical properties, the comparison of their neuroprotective and pharmacokinetic profiles, and especially their impact on memory disturbances after chronic administration to rats were investigated.

In certain scenarios, feeding at the breast is not possible, because of either maternal or neonatal reasons. In those cases, infants can still receive expressed mother's own milk (MOM) and its beneficial properties.

Much DHM research has focused on its nutritional, immunological and biochemical composition in response to various maternal variables, standard human milk banking procedures and storage protocols. The current systematic review protocol, however, aims to systematically gather and analyse existing data pertaining to the impact of these aforementioned factors on the clinical, health-related and developmental outcomes observed in infants fed with DHM.

This study aimed to examine, for the first time in male Wistar rats, pharmacodynamic (antidepressant- and anxiolytic-like) and pharmacokinetic properties of 7-(5-(4-(3-chlorophenyl)piperazin-1-yl)pentyl)-1,3-dimethyl-3,7-dihydro-1 H-purine-2,6-dione hydrochloride (GR-14).
Methods: Antidepressant- and anxiolytic-like activities have been assessed in the forced swim test (FST) and Vogel conflict drinking test, respectively.
Purpose: The study presents a cross-sectional analysis of the population of Ukrainian women who received maternity care in 11 Polish hospitals.
Methods: Multidirectional lactation counseling was implemented from March to November 2023 by the Human Milk Bank Foundation in cooperation with UNICEF Refugee Response Office in Poland. Medical data were collected using questionnaires prepared for the study.
Introduction: In recent years, Poland has faced two major emergencies: the COVID-19 pandemic, a global-scale public health emergency in 2020, and the outbreak of a full-scale war in Ukraine, which forced over 9 million Ukrainians-mostly women and children-to flee from their country through the Polish-Ukrainian border in 2022.
Methods: In 2020 and 2022, we conducted two online questionnaires with human milk bank personnel to assess the impact of these emergencies on the human milk banking sector and its preparedness to face them. All 16 human milk bank entities operating in Poland were contacted and invited to participate in the study.
Infectious and toxicological risks are the main potential hazards that operators of Human Milk Banks (HMBs) encounter and must eliminate. HMBs are trying to implement procedures that allow to manage and sanitize human milk without altering significantly its nutritional and biologically protective components, obtaining a product characterized by a valid balance between safety and biological quality. The history of human milk processing is linked to the origins of HMBs themselves.

This study explored the potential synergistic effects of combining ibuprofen with lavender essential oil (LEO) in transdermal patches. The composition of LEO was analyzed, revealing predominant compounds such as linalyl acetate and linalool, which are known for their analgesic and anti-inflammatory properties.

The material consisted of HM samples obtained from 30 exclusively breastfeeding mothers during 4-6 weeks postpartum. Additionally, to identify the factors that may potentially affect HM composition, information regarding maternal data (anthropometry, body composition, and diet) was also collected.

Background: Maternal dietary habits could affect breastmilk mineral composition, which may influence infant development. Mineral dietary intake or supplementation slightly affects its breastmilk concentration. However, the intake of selected food groups or dietary patterns that reflect diet complexity could have a greater impact.

Recently, the serotonin receptor 5-HT emerged as a promising target for AD treatment; thus, here a new series of 5-HTR ligands with a 1,3,5-triazine core and selenoether linkers was explored. Among them, the 2-naphthyl derivatives exhibited strong 5-HTR affinity and selectivity over 5-HTR (-), 5-HTR ( and ), and 5-HTR ().

According to the latest evidence, HM from vegans/vegetarians is similar in its composition to that from omnivores, however, some differences may be observed regarding vitamin B and omega-3 fatty acids concentrations. Maternal supplementation of these compounds has been proven effective in increasing their HM concentration.

Myocardial infarction with nonobstructive coronary arteries (MINOCA) remains a puzzling clinical entity. It is characterized by clinical evidence of myocardial infarction (MI) with normal or near-normal coronary arteries in angiography. Given the complex etiology including multiple possible scenarios with varied pathogenetic mechanisms, profound investigation of the plausible biomarkers of MINOCA may bring further pathophysiological insights and novel diagnostic opportunities.
