Analogs of anorexigenic neuropeptides, such as prolactin-releasing peptide (PrRP), have a potential as new anti-obesity drugs. In our previous study, palmitic acid attached to the N-terminus of PrRP enabled its central anorexigenic effects after peripheral administration. In this study, two linkers, γ-glutamic acid at Lys11 and a short, modified polyethylene glycol at the N-terminal Ser and/or Lys11, were applied for the palmitoylation of PrRP31 to improve its bioavailability. These analogs had a high affinity and activation ability to the PrRP receptor GPR10 and the neuropeptide FF2 receptor, as well as short-term anorexigenic effect similar to PrRP palmitoylated at the N-terminus...

Congenital disorders of glycosylation (CDGs) are a group of genetic diseases caused by mutations in genes that are necessary for the addition of oligosaccharides to acceptor proteins or lipids. An early step in this process requires dolichol kinase (DK) to catalyze the formation of dolichyl phosphate, which acts as a membrane anchor for initial attachment of sugar residues that are subsequently built up to oligosaccharides and transferred to acceptor proteins and lipids for further processing. Biallelic mutations in DOLK, the gene for DK, result in human in a CDG with variable symptoms, ranging from nonsyndromic dilated cardiomypopathy to severe multiorgan involvement...

In this chapter, we introduce a new area of social pharmacology that encompasses the study of the role of neuromodulators in modulating a wide range of social behaviors and brain function, with the interplay of genetic and epigenetic factors. There are increasing evidences for the role of the neuropeptide oxytocin in modulating a wide range of social behaviors, in reducing anxiety, and in impacting the social brain network. Oxytocin also promotes social functions in patients with neuropsychiatric disorders, such as autism and reduces anxiety and fear in anxiety disorders...

This article will review the evidence of various proposed factors that contribute to the onset and maintenance of hoarding disorder (HD). Data suggests that hoarding is a chronic condition that starts early in life and does not remit if left untreated. There is emerging evidence that a number of factors contribute to the expression of HD symptoms, including genetics, neurocognitive functioning, attachments to possessions, beliefs, avoidance, personality factors, and life events. The extent to which each etiological factor uniquely contributes to hoarding is still unknown...

Inhibited attachment disordered behavior (IADB) is characterized by difficulty in establishing an attachment relationship with a primary caregiver; is associated with persistent social and emotional problems; and is observed most frequently in contexts of pathological care such as institutional rearing. Here, we seek to enhance understanding of the conditions that give rise to IADB among institutionalized children by examining prior family experiences of neglect and deprivation and concurrent relational experiences at the institution...

A 41-year-old woman (G3P2L2Ab1) was referred to gynecology clinic with chief complaints of abdominal distension and localized abdominal wall pruritus for three months. She was misdiagnosed with gastrointestinal disorder and ultimately had undergone imaging. Ultrasonography and computed tomography (CT) scan disclosed a huge solid-cystic mass originating from the ovary. On clinical examination the patient had no pain or tenderness and no gynecologic complaints. Laboratory tests showed normal tumor markers and hemoglobin at 8 g/dl...

BACKGROUND: Previous research has documented increased incidence of insecure attachment and theory of mind (ToM) deficits in individuals experiencing psychotic disorders. ToM has been theorized as a possible mediator of the relation between attachment and psychosis (Korver-Nieberg et al., 2014). The current study sought to extend this area of research to adolescents for the first time by examining adolescent-parent attachment and ToM in inpatient adolescents. METHODS: Participants were 362 inpatient adolescents and their parents; participants completed the Child Attachment Interview, Movie for the Assessment of Social Cognition, Youth Self Report, and Child Behavior Checklist...

BACKGROUND: Polypropylene implants are used for the reconstructive surgery of urogynaecological disorders like pelvic organ prolapse, but severe complications associated with their use have been reported. There is evidence that surface properties and a difference in mechanical stiffness between the implant and the host tissue contribute to these adverse events. Electrospinning is an innovative engineering alternative that provides a biomimetic microstructure for implants, resulting in a different mechano-biological performance...

It has been proposed that cholesterol in host cell membranes plays a pivotal role for cell entry of HIV. However, it remains largely unknown why virions prefer cholesterol-rich heterogeneous membranes to uniformly fluid membranes for membrane fusion. Using giant plasma membrane vesicles containing cholesterol-rich ordered and cholesterol-poor fluid lipid domains, we demonstrate that the HIV receptor CD4 is substantially sequestered into ordered domains, whereas the co-receptor CCR5 localizes preferentially at ordered/disordered domain boundaries...

BACKGROUND: Significant mental health disparities exist for Hispanic populations, especially with regard to depression treatment. Stigma and poor communication between patients and their providers result in low use of antidepressant medications and early treatment withdrawal. Cultural factors which influence treatment decisions among Hispanics include fears about the addictive and harmful properties of antidepressants, worries about taking too many pills, and the stigma attached to taking medications...

OBJECTIVES: The US ranks ninth in obesity in the world, and approximately 7% of US adults experience major depressive disorder. Social isolation due to the stigma attached to obesity might trigger depression. METHODS: This paper examined the impact of obesity on depression. To overcome the endogeneity problem, we constructed pseudopanel data using the Behavioral Risk Factor Surveillance System from 1997 to 2008. RESULTS: The results were robust, and body mass index (BMI) was found to have a positive effect on depression days and the percentage of depressed individuals in the population...

X-linked hypophosphatemia (XLH) is a dento-osseous disorder caused by inactivating mutations in the PHEX gene, leading to renal phosphate wasting and hypophosphatemia, and impaired mineralization of bones and teeth. In the oral cavity, recent reports suggest a higher susceptibility of XLH patients to periodontitis, where patients present with impaired tooth cementum - a bone-like tissue involved in tooth attachment to the jaw bones and post-eruption tooth positioning - and a higher frequency of intrabony defects...

OBJECTIVE: The overvaluation of body shape and weight of persons with eating disorders (EDs) is putatively explained by a disturbance in the way they experience their own body (embodiment). Moreover, attachment disorders seem to promote the use of body as source for self-definition. Therefore, we assessed the role of embodiment in the connection between attachment styles and ED psychopathology. METHOD: One-hundred and thirteen ED patients and 117 healthy subjects completed the Identity and Eating Disorders (IDEA) Questionnaire, the Eating Disorder Inventory-2 (EDI-2) and the Experiences in Close Relationships Scale...

The nucleus of the tractus solitarius (NTS) is a brain stem region critical to many physiologic processes and has been implicated in addiction to multiple classes of abused drugs, including alcohol (EtOH). That said, the mechanism by which EtOH modulates NTS neurocircuit activity is not well characterized and has yet to be examined utilizing electrophysiologic methods in mouse models of alcohol use disorders. To begin to address this gap in knowledge, we sought to use whole-cell and cell-attached recordings to determine the mechanism of acute EtOH action on GABAergic and glutamatergic neurotransmission, as well as on action potential firing in the NTS of adult male, EtOH naïve mice...
