Patients with craniopharyngioma show symptoms linked to the location of the tumour close to the optic pathways, hypothalamus and pituitary gland, such as increased intracranial pressure, endocrine deficiencies and visual defects

Treatment is not specific and mostly non-curative, and frequently includes surgery, which may achieve gross-total or partial resection, followed by radiotherapy. In cystic tumours, frequent drainage is often required and intracystic instillation of drugs has been used to help manage cyst refilling. More recently targeted therapies have been used, particularly in papillary craniopharyngioma, but also now in adamantinomatous craniopharyngioma and clinical trials are underway or in development. Although patient survival is high, the consequences of the tumour and its treatment can lead to severe comorbidities resulting in poor quality of life, in particular for those patients that bear tumours with hypothalamic involvement. Accordingly, in  vitamin b2 deficiency diseases  at risk for the development of a hypothalamic syndrome hypothalamus-sparing treatment strategies such as limited resection followed by irradiation are recommended. In this review, we provide an update on various aspects of craniopharyngioma, with emphasis on recent advances in the understanding of Endocrine Society.

A series of small (7-12 mer) amphipathic cationic peptides were designed and synthesized to create short helical peptides with broad-range bactericidal activity and selectivity toward the bacterial cells. The analysis identified a lead 12-mer peptide 8b with broad-spectrum activity against Gram-positive (MIC = 1-2 μg/mL) and Gram-negative (MIC = 2-5 μg/mL) bacteria and selectivity toward prokaryotic versus eukaryotic cells (HC(50) = 280 μg/mL, >75% cell viability at 150 μg/mL). The rapid membranolytic action of 8b was demonstrated by a calcein dye leakage assay and confirmed using scanning electron microscopy. According to circular dichroism and NMR spectroscopy, the peptides have an irregular spatial structure in water. A lipid bilayer induced an amphipathic helix only in 12-mer peptides, including 8b.

Molecular dynamics simulations provided detailed information about the interaction of 8b and its closest analogues with bacterial and mammalian membranes and revealed the roles of particular amino acids in the activity and selectivity of peptides.

BACKGROUND: Chlamydia trachomatis (CT) infection is the most prevalent sexually transmitted bacterial disease worldwide whose greatest impact is on the female reproductive system. The objective was to assess the prevalence of Chlamydia infection in a large population of female patients from a private health service in São Paulo (Brazil), identifying the main age groups affected by the agent and the evolution of the prevalence.

METHODS: A cross-sectional study was conducted based on the results of all molecular biology tests. The tests were carried out determined by year and age group. RESULTS: A total of 85,292 patients who performed 103,576 tests for Chlamydia were considered eligible for the statistical data. The overall prevalence of C. trachomatis infection in the study population was 2% (95% CI: 07-25). A higher prevalence of infection was observed in the ≤ 25 years and ≤ 30 years age groups, with rates of 0% (95% CI: 59-35) and 4% (95% CI: 08-50), respectively. There was a significant increase in the positivity of the exams over time, especially in the ≤ 35 years age group.

The prevalence at 26-30 years was 1% (95% CI: 82-30); 31-35 years 7% (95% CI: 50-82); 36-40 years 0% (95% CI: 86-16); 41-60 years 6% (95% CI: 50-70) and the prevalence at ≥ 61 years was 4% (95% CI: 11-75). CONCLUSION: The screening of asymptomatic young women would Rua Dr Cesário Mota Jr, 112 - Vila Buarque, São Paulo, 01221- 020, Brazil. hippocampal neuronal activity and anxiety behavior in mice. Gold nanoparticles (GNPs) have been widely used in medicine such as imaging, drug delivery and therapeutics due to their multifunctional properties. Alterations in neuronal function may contribute to various neurological diseases. Transferrin plays a primary role in iron transportation and delivery and has recently been utilized for drug delivery to the brain. We have investigated effects of transferrin-conjugated GNPs (Tf-GNPs) on anxiety and locomotor behavior in vivo and also hippocampal neuronal activity ex vivo.

Electrophysiological effects of Tf-GNP on hippocampal neurons were determined by patch clamp method. Fifteen male young adult C57BL/6 mice were randomly divided into three groups as control (200 µL PBS), GNP (bare GNP; 2 μg/g in PBS) and Tf-GNPs (2 μg/g Tf-GNP). Animals intraperitoneally received the respective treatments for seven consecutive days and were subjected to elevated plus maze (EPM) and open field tests (OFT). Ex vivo, firing frequency of the neurons significantly increased by GNP treatment (p < 001).
