Low consumption of n-3 polyunsaturated fatty acids (PUFA) during the developmental period has been increasingly associated with an increased risk of depressive-like symptoms in both male and female sexes. Therefore, here we performed behavioral and biochemical quantifications in adolescent rats to evaluate possible sex-driven differences in the development of anxiety-like disorders related to life-long n-3 PUFA low intake. Male and female adolescent rats fed for their entire life with n-3 PUFA poor diet showed an anxiety-like profile compared to n6/n-3 PUFA balanced diet.

Autism spectrum disorders (ASD) are highly heterogeneous neurodevelopmental diseases. Epidemiological data report that males have been diagnosed with autism more frequently than females. However, recent studies hypothesize that females' low incidence might be underestimated due to standard clinical measures of ASD behavioural symptoms, mostly derived from males.

Autism Spectrum Disorders (ASD) are principally diagnosed by three core behavioural symptoms, such as stereotyped repertoire, communication impairments and social dysfunctions. This complex pathology has been linked to abnormalities of corticostriatal and limbic circuits. Despite experimental efforts in elucidating the molecular mechanisms behind these abnormalities, a clear etiopathogenic hypothesis is still lacking.

Hemp is considered one of the potential novel crops for human and animal nutrition. This study aimed to determine the complete chemical composition of 29 different varieties of whole hempseeds. Fatty acid composition, amino acid profile, mineral composition, and cannabinoids content were also evaluated.

Article Synopsis
  • The study explores the impact of preconception stress on the neurodevelopment of male offspring from socially isolated female rats compared to those from group-reared females.
  • It examines various behavioral tests (passive avoidance, novel object recognition, and open field) as well as neurochemical changes, such as levels of noradrenaline and serotonin in the offspring.
  • Results indicated that offspring from socially isolated mothers exhibited alterations in behavior and neurochemistry, including decreased latency in learning tasks and changes in neurotransmitter levels, suggesting that early social deprivation affects neurodevelopment postnatally.

Article Synopsis
  • - Sorghum grain is a nutritious, gluten-free cereal rich in antioxidants and minerals, with a study analyzing 16 varieties grown in Serbia to assess their phenolic composition and antioxidant activity.
  • - The research identified nine specific phenolic compounds in sorghum grains and evaluated their antioxidant potential using various spectroscopy methods, revealing that some samples had higher levels of these compounds and stronger antioxidative properties.
  • - The study also found that sorghum can meet daily requirements for key macro- and microelements, and utilized pattern recognition techniques to differentiate between samples based on their phenolic profiles and elemental analysis, while exploring the interaction of specific compounds with radicals using Density Functional Theory.

Periodontal disease (PD) is a chronic inflammatory disorder characterized by the destruction of connective tissue, tooth loss, and systemic infections. Clinically, treatment of PD includes control of the etiologic factors via several modalities: initial therapy including scaling and root planing (SRP), corrective phase of surgical treatment, both with and without adjunct antimicrobial/pharmacological agents, followed by a maintenance/supportive periodontal therapy phase. Each treatment phase aims to control oral biofilm by addressing risk factors and etiology.

Article Synopsis
  • - The study focuses on endometrioid adenocarcinomas (EA), common malignant tumors of the uterus, examining how microvascular density (MVD) in EA tissues relates to tumor characteristics.
  • - Researchers analyzed 30 cases of EA, finding that higher MVD correlates with tumor grade and FIGO stage, along with changes in specific proteins related to tumor behavior and metastasis.
  • - The conclusion suggests that as EA progresses, changes in tumor cell and stroma characteristics occur, indicating that these molecular behaviors can help predict disease outcomes.

Many types of differentiated cells can reenter the cell cycle upon injury or stress. The underlying mechanisms are still poorly understood. Here, we investigated how quiescent cells are reactivated using a zebrafish model, in which a population of differentiated epithelial cells are reactivated under a physiological context.

In the United States, about one million people are seen to visit the operating theater for cardiac surgery annually. However, nearly half of these visits result in complications such as renal, neurological, and cardiac injury of varying degrees. Historically, many mechanisms and approaches have been explored in attempts to reduce injuries associated with cardiac surgery and percutaneous procedures.

The heart is a rare site of cancer metastases, even from the most common malignancies, such as lung cancer. Cardiac metastases may lead to myocardial dysfunction. This report presents a case of lung cancer metastases to the left ventricular myocardium that clinically manifested as atypical symptoms of cardiac dysfunction.

The conflict in Ukraine, which started when Russia invaded and violated its sovereignty, has led to the country's worst war since the annexation of Crimea in 2014. The war has resulted in a significant number of casualties, displaced millions of people, and damaged the healthcare system, which was already struggling before the conflict. The neurosurgical field, in particular, has been severely affected, with infrastructure and healthcare systems routinely demolished or interrupted in conflict zones, making fundamental medical operations unavailable to victims of armed conflict.

In March 2020, WHO declared SARS-CoV-2 a global pandemic and lockdowns were enforced in most of the United States. Self-protective measures and travel restrictions were implemented, and schools/universities initiated online learning. Consequently, the global incidence and hospitalization rates of seasonal respiratory infections decreased significantly up to early 2021.

Glioblastoma Multiforme (GBM) is a debilitating type of brain cancer with a high mortality rate. Despite current treatment options such as surgery, radiotherapy, and the use of temozolomide and bevacizumab, it is considered incurable. Various methods, such as drug repositioning, have been used to increase the number of available treatments.
