Non-Drug and Non-Invasive Therapeutic Options in Alzheimer's Disease.

Despite the massive efforts of modern medicine to stop the evolution of Alzheimer's disease (AD), it affects an increasing number of people, changing individual lives and imposing itself as a burden on families and the health systems. Considering that the vast majority of conventional drug therapies did not lead to the expected results, this review will discuss the newly developing therapies as an alternative in the effort to stop or slow AD. Focused Ultrasound (FUS) and its derived Transcranial Pulse Stimulation (TPS) are non-invasive therapeutic approaches.

Glioblastoma Microenvironment and Cellular Interactions.

The central nervous system (CNS) represents a complex network of different cells, such as neurons, glial cells, and blood vessels. In tumor pathology, glial cells result in the highest number of cancers, and glioblastoma (GB) is considered the most lethal tumor in this region. The development of GB leads to the infiltration of healthy tissue through the interaction between all the elements of the brain network.

Partnering bevacizumab with irinotecan as first line-therapy of metastatic colorectal cancer improves progression free survival-A retrospective analysis.

Colorectal cancer remains one of the most frequent malignancies (third place at both genders) worldwide in the last decade, owing to significant changes in modern dietary habits. Approximately half of the patients develop metastases during the course of their disease. The available therapeutic armamentarium is constantly evolving, raising questions regarding the best approach for improving survival.

Interplay between metabolic and thyroid parameters in obese pubertal children. Does visceral adipose tissue make the first move?

: The mechanisms of obesity-associated thyroid dysfunction in children are incompletely deciphered. We aimed to evaluate whether visceral adipose tissue (VAT), insulin resistance (IR), inflammation, oxidative stress (OS) are involved in thyroid morpho-functional changes in pubertal obese children. : We recruited 43 obese pubertal children without history of thyroid pathology.

State of the art in human adipose stem cells and their role in therapy.

Nowadays, adipose tissue appears to be the most valuable source in regenerative cell therapy, due to the following characteristics: high accessibility, high expression in a large number of individuals, high self-renewal and ability to differentiate, and hematopoietic support to the implant area. Its therapeutic potential has been experimentally observed in a broad spectrum of diseases with high population impact: diabetes, myocardial infarction, Parkinson disease, bone fractures, facial reconstruction or loss of subcutaneous tissue due to congenital abnormalities (e.g.

Vitamin D deficiency, insulin resistance and thyroid dysfunction in obese patients: is inflammation the common link?

The aim of this article is to study the possible relation of serum vitamin D concentrations to body mass index (BMI), visceral fat thickness (VFT), insulin resistance (IR), inflammation (serum monocyte chemoattractant protein-1 - MCP-1) and thyroid parameters in obese patients. A total of 158 non-diabetic, obese patients aged 19-68 without a history of thyroid pathology were recruited. Biochemical markers, insulin, 25-OH vitamin D, thyroid parameters (TSH, FT3, FT4, TPO antibodies, TG antibodies) and VFT were measured.

Genotype-phenotype Analysis of Paraoxonase 1 in Schizophrenic Patients Treated with Atypical Antipsychotics.

Objective: Recent studies suggest a possible involvement of low paraoxonase 1 (PON1) enzyme activities in the association between schizophrenia, treatment with atypical antipsychotics and increased cardiovascular (CVD) risk. In the present study, we aimed at investigating the PON1 status in a group of schizophrenic patients treated with either olanzapine or other antipsychotic, as compared to a group of healthy control participants.

Methods: We assessed the arylesterase (AREase) and paraoxonase (POase) activities of PON1, as well as three common polymorphisms of gene (Q192R, L55M, -108C＞T).

Low Retinal Dehydrogenase 1 (RALDH1) Level in Prepubertal Boys with Autism Spectrum Disorder: A Possible Link to Dopamine Dysfunction?

Objective: Retinal dehydrogenase 1 (RALDH1) is a cytosolic enzyme which acts both as a source of retinoic acid (RA) and as a detoxification enzyme. RALDH1 has key functions in the midbrain dopaminergic system, which influences motivation, cognition, and social behavior. Since dopamine has been increasingly linked to autism spectrum disorder (ASD), we asked whether RALDH1 could contribute to the autistic phenotype.

Chondroprotective effects of pulsed shortwave therapy in rabbits with experimental osteoarthritis.

Introduction: Osteoarthritis (OA) represents a public health challenge since the pathogenic treatment, able to induce cartilage regeneration, still remains unknown. Ageing of the population and increasing OA prevalence have led to a lot of research, aiming to identify treatments acting on chondrocytes that play a determinant role in cartilage degeneration÷regeneration balance. Pulsed shortwave therapy (with the classical application form - Diapulse) is a physiotherapy method with anabolic effects demonstrated on nervous, conjunctive and vascular tissues, but its effects on OA cartilage are not known.

Solitary Langerhans histiocytosis of the orbit: case report and review of the literature.

Langerhans cell histiocytosis (LCH), previously known as "histiocytosis X", is a clinical entity characterized by abnormal proliferation of Langerhans cells, which exert a mass effect. Orbital involvement due to LCH is rare as a unifocal disease, seldom occurring outside the pediatric population. We report a case of a 21-year-old man with solitary LCH of the orbit depicted by magnetic resonance imaging (MRI) and diagnosed by histopathological examination.

Paraoxonase-1 activities in children and adolescents with type 1 diabetes mellitus.

Background: Paraoxonase-1 is an HDL-associated esterase that acts as an anti-atherogenic agent by protecting LDL from oxidation. This study investigates paraoxonase-1 activities in children and adolescents with type 1 diabetes mellitus and possible associations with other biochemical markers.

Patients And Methods: The study enrolled 82 children and adolescents with type 1 diabetes mellitus and 41 controls with similar age and gender distribution.

Evaluation of whole blood zinc and copper levels in children with autism spectrum disorder.

Zinc (Zn) and copper (Cu) are important trace elements for cognitive development and normal neurological functioning. Autism spectrum disorder (ASD) is a common neurological disorder, which has previously been associated with the levels of some trace elements in the blood. However, clinical data regarding the potential implication of Zn and Cu in patients with ASD are still insufficient.

Paraoxonase 1 genotype-phenotype correlation in patients with metabolic syndrome.

The aim of the study was to investigate the influence of three single nucleotide polymorphisms (SNPs) (-108C>T, -162A>G and -909G>C) from the promoter region of paraoxonase 1 (PON1) gene on the enzyme activity, in patients with metabolic syndrome (MS). The study group consisted of 61 individuals with MS and the control group of 73 individuals without MS, matched for age and gender. For each individual, clinical and genetic parameters with possible influence on PON1 activities (paraoxonase, arylesterase and lactonase) were measured.

Serum homocysteine levels, oxidative stress and cardiovascular risk in non-alcoholic steatohepatitis.

Introduction: Hyperhomocysteinemia is considered an independent risk factor for cardiovascular disease. Oxidative stress is one of the major pathogenic mechanisms in non-alcoholic fatty liver disease and atherosclerosis.

Aim: Our study aimed to evaluate serum homocysteine levels and oxidative stress in patients with biopsy-proven non-alcoholic steatohepatitis and possible association with cardiovascular risk measured by carotid artery intima-media thickness (c-IMT).

Diagnostic correlation between RET proto-oncogene mutation, imaging techniques, biochemical markers and morphological examination in MEN2A syndrome: case report and literature review.

Multiple endocrine neoplasia type 2 (MEN2) is a rare autosomal dominant monogenic disorder caused mostly by missense mutations in the RET (REarranged during Transfection) proto-oncogene on chromosome 10q11.2. MEN2A represents more than 50% of all MEN2 cases, having a regular pattern with medullary thyroid carcinoma (MTC) incidence of 90-100%, bilateral pheochromocytoma (PCC) incidence of 40-50% and primary hyperparathyroidism (HPT) incidence of 10-25%.

One carbon metabolism disturbances and the C677T MTHFR gene polymorphism in children with autism spectrum disorders.

Autism spectrum disorders (ASDs), which include the prototypic autistic disorder (AD), Asperger's syndrome (AS) and pervasive developmental disorders not otherwise specified (PDD-NOS), are complex neurodevelopmental conditions of unknown aetiology. The current study investigated the metabolites in the methionine cycle, the transsulphuration pathway, folate, vitamin B(12) and the C677T polymorphism of the MTHFR gene in three groups of children diagnosed with AD (n= 15), AS (n= 5) and PDD-NOS (n= 19) and their age- and sex-matched controls (n= 25). No metabolic disturbances were seen in the AS patients, while in the AD and PDD-NOS groups, lower plasma levels of methionine (P= 0.
