Proteins are biological macromolecules involved in a wide range of biological functions, which makes them very appealing as therapeutics agents. Indeed, compared to small molecule drugs, their endogenous nature ensures their biocompatibility and biodegradability, they can be used in a large range of applications and present a higher specificity and activity. However, they suffer from unfolding, enzymatic degradation, short half-life and poor membrane permeability. To overcome such drawbacks, the development of protein delivery systems to protect, carry and deliver them in a controlled way have emerged importantly these last years. In this review, the formulation of a wide panel of protein delivery systems either in the form of polymer or inorganic nanoengineered colloids and scaffolds are presented and the protein loading and release mechanisms are addressed. A section is also dedicated to the detection of proteins and the characterization methods of their release. Then, the main protein delivery systems developed these last three years for anticancer, tissue engineering or diabetes applications are presented, as well as the major in vivo models used to test them. The last part of this review aims at presenting the perspectives of the field such as the use of protein-rich material or the sequestration of proteins. This part will also deal with less common applications and gene therapy as an indirect method to deliver protein.
This study aimed to determine the role of brain MRI post-processing method MAP07 (Morphometric Analysis Program) in detecting epileptogenic brain lesions in patients with pharmacoresistant epilepsy (PE). MAP07 is a sophisticated diagnostic program that offers several morphometric maps and facilitates the detection and localization of hippocampal sclerosis (HS), focal cortical dysplasias (FCD), and other types of cortical malformations, which could be undetected by conventional visual MRI analysis (CVA).

120 patients aged > 16 years with PE have been recruited. 3 T MRI was performed according to epilepsy imaging protocol followed by image postprocessing with a fully automated MATLAB script, MAP07, by applying SPM5 algorithms. Statistical analysis was performed in IBM SPSS Statistics, version 25.0.

Analysis in our patients showed a high sensitivity of MAP07 with low specificity and with a high proportion of false-positive patients. After MRI analysis, out of 120 patients, 32 were found to have no structural abnormalities by conventional visual analysis in whom after MAP07 in 5 patients structural lesions were found (in one HS, in one FCD, in two perinatal vascular lesions, and in one hippocampal hyperintensity). There was a quite high overall coincidence of the findings of MAP07 and MRI for the detection of FCD, HS, perinatal ischemia/chronic vascular lesions, heterotopias, and polymicrogyria (kappa coefficient above 0.700).

MAP07 analysis is a useful, additional, and automated method that may guide re-evaluation of MRI by highlighting suspicious cortical regions, as a complementary method to CVA, by enhancing the visualization of cortical malformations and lesions.

Endoscopic third ventriculostomy (ETV) has now become an accepted mode of hydrocephalus treatment. However, the long-term effects of ETV for myelomeningocele-related hydrocephalus (MMC-rH) after shunt malfunction remains unclear. We aimed to assess the long-term outcome and the factors associated with the success of ETV for MMC-rH after shunt malfunction.

We performed a retrospective analysis of data collected between 2001 and 2018 from 8 patients with MMC-rH after shunt malfunction, who underwent ETV at the Kurume University Hospital and were followed up for at least 5 years. We extracted data regarding age, sex, clinical symptoms, radiological imaging, intraoperative findings, and outcomes.

The overall success rate was 62.5% and their ETV success score is 67.5. The most frequent clinical symptom was intracranial hypertension symptoms (100 %), followed by Chiari type II symptoms (87.5 %). In preoperative MRI scans, we observed aqueduct stenosis in 6 cases, Chiari type II malformations in 7 cases, four patients had a narrow prepontine cistern, five patients had an absent septum pellucidum, and three presented with stenosis of the foramen of Monro. All cases in the failure group had the above 5 symptoms. Based on intraoperative findings, a thick third ventricle floor was found in 5 patients. Two patients had a thin hypothalamic adhesion in the third ventricle floor. They had no major complications.

ETV for MMC-rH after shunt malfunction is an effective treatment option. However, we recommend that a neurosurgeon with extensive experience in neuroendoscopy perform ETV because MMC patients more often had intraventricular malformations than those with other hydrocephalus diseases.

However, little is known about the changes of BDNF and its precursor proBDNF in lymphocytes. In addition, earlier studies using commercial ELISA kits cannot distinguish mature BDNF from proBDNF. We aimed to investigate the change of mBDNF and proBDNF levels in the peripheral blood and their diagnostic value in the mood disorders using a specific Enzyme-Linked Immunosorbent Assay (ELISA). Serum mBDNF levels were significantly decreased in major depressive disorder (MDD) (n = 90) and bipolar disorder (BD) (n = 15) groups (P less then 0.0001), whereas there was no significant change in suicidal group (n = 14) compared to the control group (n = 96). In the subgroups of MDD, the serum mBDNF level in MDD patients with severe symptoms was significantly lower than that with moderate symptoms (P less then 0.05).
