Several studies have shown an imbalance between proinflammatory and anti-inflammatory cytokines in depression and anxiety disorders. However, less attention has been paid to the role of cytokines in psychological disorder in mothers who breastfeed. This study looks at whether concentration levels of TGF-β2 are altered in anxious and depressive breastfeeding mothers. This study checked the concentration level of TGF-B2 in relation with psychological symptoms on 110 breastfeeding mothers; based on random sampling method with using of Beck Depression Inventory (BDI), General Health Questionnaire (GHQ) and Spielberger Stress Scale (STAI) in 2015 also TGF-β2 was measured in breast milk using ELISA...

Migraine has been reported as a risk factor for ischemic stroke or cardiovascular events, and dysfunction of endothelial cells has been evidenced in migraine patients. Proangiogenic factors are potential endothelial stimulators, and their disturbances can link abnormalities of endothelium with increased risk of vascular disorders. The aim of this study was to evaluate the levels of circulating proangiogenic factors in sera of migraineurs during interictal period. Fifty-two patients aged 37.9 ± 9.6 years, fulfilling International Headache Society criteria for migraine, were included in this observational case-control study...

Parkinson's disease (PD) is the second most common neurodegenerative disease. It is characterized by aggregation of the protein α-synuclein (α-syn) in Lewy bodies, mitochondrial dysfunction, and increased oxidative stress in the substantia nigra. Oxidative stress leads to several modifications of biomolecules including dityrosine (DiY)-crosslinking in proteins, which has recently been detected in α-syn in Lewy bodies from PD patients. Here we report that α-syn is highly susceptible to UV-induced DiY formation...

Geleophysic dysplasia, belonging to the group of acromelic dysplasia, is a rare genetic disease. Two genes, FBN1 and ADAMTSL2, were known to be linked to this disorder. The disorder presents as extreme short stature, short limbs, small hands and feet, stubby fingers and toes, joint stiffness, toe walking, skin thickening, progressive cardiac valvular thickening and characteristic facial features, including a round face with full cheeks. Here, we report the first Chinese case with geleophysic dysplasia type 1 based on clinical and genetic features...

Early-life stress (ES) is a risk factor for metabolic disorders (e.g. obesity) with a notoriously higher prevalence in women compared to men. However, mechanisms underlying these effects remain elusive. The development of the hypothalamic feeding and metabolic regulatory circuits occurs mostly in the early sensitive postnatal phase in rodents and is tightly regulated by the metabolic hormones leptin and ghrelin. We have previously demonstrated that chronic ES reduces circulating leptin and alters adipose tissue metabolism early and later in life similarly in both sexes...

In mammals, STAT3 (Signal transducer and activator of transcription 3) plays an important role in growth, multiplication, differentiation and participates in inflammation, tumorigenesis, metabolic disorders and immune response. STAT3 is a protein that shuttles between the nucleus and cytoplasm. Compared to the STAT3 in cell nucleus, we did not know the function of STAT3 in cytoplasm for a long time. Some recent studies have shown that cytoplasmic STAT3 regulates autophagy through the interaction with the double-stranded RNA-activated protein kinase (PKR), which plays an important role in cellular antiviral response...

INTRODUCTION: Glycerol phenylbutyrate (GPB) is approved in the US for the management of patients 2months of age and older with urea cycle disorders (UCDs) that cannot be managed with protein restriction and/or amino acid supplementation alone. Limited data exist on the use of nitrogen conjugation agents in very young patients. METHODS: Seventeen patients (15 previously on other nitrogen scavengers) with all types of UCDs aged 2months to 2years were switched to, or started, GPB...

Growth hormone deficiency (GHD) is a relatively uncommon and heterogeneous endocrine disorder presenting in childhood with short stature. However, during the neonatal period, the metabolic effects of GHD may to require prompt replacement therapy to avoid possible life-threatening complications. An increasing amount of data suggests the importance of an early diagnosis and treatment of GHD because of its auxological, metabolic, and neurodevelopmental features with respect to the patients diagnosed and treated later in life...

Deciphering the links between amino acid sequence and amyloid fibril formation is key for understanding protein misfolding diseases. Here we use Monte Carlo simulations to study the aggregation of short peptides in a coarse-grained model with hydrophobic-polar (HP) amino acid sequences and correlated side chain orientations for hydrophobic contacts. A significant heterogeneity is observed in the aggregate structures and in the thermodynamics of aggregation for systems of different HP sequences and different numbers of peptides...

Adipose tissue includes multiple anatomical depots that serve as an energy reserve that can expand or contract to maintain metabolic homeostasis. During normal growth and in response to overnutrition, adipose tissue expands by increasing the volume of preexisting adipocytes (hypertrophy) and/or by generating new adipocytes (hyperplasia) via recruitment and differentiation of adipose progenitors. This so-called healthy expansion through hyperplasia is thought to be beneficial in that it protects against obesity associated metabolic disorders by allowing for the "safe" storage of excess energy...

Pulmonary artery hypertension (PAH) is a rare and fatal disorder with extensive remodeling of pulmonary arteries mediated by hyperproliferation of pulmonary artery smooth muscle cell (PASMC). Aberrant platelet-derived growth factor (PDGF) activity can lead to hyperproliferation of PASMC, however, little is known about the role of long noncoding RNA (lncRNA) in this process. Using RNA sequencing (RNA-seq), we identified 725 lncRNAs in rat PASMC (RPASMC), 95 of which were expressed differentially in response to PDGF-BB treatment...

The number and amount of man-made chemicals present in the aquatic environment has increased considerably over the past 50 years. Among these contaminants, endocrine-disrupting chemicals (EDCs) represent a significant proportion. This family of compounds interferes with normal hormonal processes through multiple molecular pathways. They represent a potential risk for human and wildlife as they are suspected to be involved in the development of diseases including, but not limited to, reprotoxicity, metabolic disorders, and cancers...

Cryptorchidism is the most common congenital disorder in boys, but the cause for most cases remains unknown. Patients with Noonan Syndrome are characterized by a typical face, growth retardation, congenital heart defects, learning disabilities and cryptorchidism. Copy number variations of Ras/MAPK pathway genes are unusual in patients with several clinical features of Noonan Syndrome; however, they have not been studied in patients with only one feature of this condition, such as cryptorchidism. Our aim was to determine whether patients with isolated cryptorchidism exhibit Ras/MAPK pathway gene copy number variations (CNVs)...

Sleep serves crucial learning and memory functions in both nervous and immune systems. Microglia are brain immune cells that actively maintain health through their crucial physiological roles exerted across the lifespan, including phagocytosis of cellular debris and orchestration of neuroinflammation. The past decade has witnessed an explosive growth of microglial research. Considering the recent developments in the field of microglia and sleep, we examine their possible impact on various pathological conditions associated with a gain, disruption, or loss of sleep in this focused mini-review...

The neuroligin (Nlg) family of neural cell adhesion molecules is thought to be required for synapse formation and development, and has been linked to the development of autism spectrum disorders in humans. In Drosophila melanogaster, mutations in the neuroligin 1-3 genes have been reported to induce synapse developmental defects at neuromuscular junctions (NMJs), but the role of neuroligin 4 (dnlg4) in synapse development has not been determined. Here, we report that the Drosophila neuroligin 4 (DNlg4) is different from DNlg1-3 that it presynaptically regulates NMJ synapse development...
