Objective.:  Post-traumatic stress disorder (PTSD) and somatic symptoms, such as pain, are frequently seen in refugees. Their relationship is poorly understood, and the treatment of these comorbid conditions can be very challenging. The current cross-sectional study examined pain and other somatic symptoms and their relationship with trauma history, PTSD symptom clusters, and current living difficulties among treatment-seeking refugees. Methods.:  One hundred thirty-four treatment-seeking traumatized refugees (78% male, mean age = 42 years) were assessed regarding lifetime traumatic experiences, symptoms of post-traumatic stress, overall pain and somatic symptoms, and postmigration living difficulties...

Schizophrenia spectrum disorder (SCZD), autism spectrum disorder (ASD), and obsessive-compulsive spectrum disorder (OCSD) are considered as three separate psychiatric conditions with, supposedly, different brain alterations patterns. From a neuroimaging perspective, this meta-analytic study aimed to address whether this nosographical differentiation is actually supported by different brain patterns of gray matter (GM) or white matter (WM) morphological alterations. We explored two possibilities: (a) to find out whether GM alterations are specific for SCZD, ASD, and OCSD; and (b) to associate the identified brain alteration patterns with cognitive dysfunctions by means of an analysis of lesion decoding...

Drosophila represents an excellent model to dissect the roles played by the evolutionary conserved family of eukaryotic dyskerins. These multifunctional proteins are involved in the formation of H/ACA snoRNP and telomerase complexes, both involved in essential cellular tasks. Since fly telomere integrity is guaranteed by a different mechanism, we used this organism to investigate the specific role played by dyskerin in somatic stem cell maintenance. To this aim, we focussed on Drosophila midgut, a hierarchically organized and well characterized model for stemness analysis...

The human body develops from a single cell, the zygote, the product of the maternal oocyte and the paternal spermatozoon. That 1-cell zygote embryo will divide and eventually grow into an adult human which is comprised of ~3.7 × 10(13) cells. The tens of trillions of cells in the adult human can be classified into approximately 200 different highly specialized cell types that make up all of the different tissues and organs of the human body. Regenerative medicine aims to replace or restore dysfunctional cells, tissues and organs with fully functional ones...

The members of the Src family of nonreceptor tyrosine kinases (SFKs) are implicated in multiple signaling processes that regulate key cellular functions, including proliferation, migration, differentiation, and survival. SFKs are activated by a large number of receptors for growth factors, cytokines, steroid hormones, G protein-coupled receptors, and also by adhesion proteins and other signaling partners. Through their common modular kinase an adapter protein domains, SFKs critically contribute to diversify different signal inputs, weaving a complex and dynamic network of cellular responses...

OBJECTIVE: A major terror attack occurred in the Paris region on 13th November 2015. This event was widely showed, described, and commented in the media. Media consumption may lead to a widespread diffusion of trauma-related symptoms following a collective trauma. These effects may depend on the type of media and emotion regulation strategies used by the media consumer. METHOD: Trauma history, traumatic symptoms, media consumption, psychological distress, and emotion regulation strategies of 451 young adults were assessed by an online survey...

Telomerase expression and activity appear elevated in >80% of human cancers. The activity of the telomerase may serve as a diagnostic marker for malignancy, and an indicator of the proliferative potential of somatic and stem cells. The telomeric repeat amplification protocol (TRAP) is a sensitive and accurate PCR-based assay for telomerase detection and measurement. Here, we describe a quantitative PCR-based TRAP assay (qTRAP) that is more convenient and amenable to high-throughput applications compared to traditional gel-based TRAP assays...

Context: Gastrointestinal Stromal Tumors (GISTs) are mesenchymal tumors of the gastrointestinal tract arising from the interstitial cells of Cajal. Succinate dehydrogenase (SDH) deficient GISTs are a unique class of GIST defined by: loss of immunohistochemical expression of SDHB indicating dysfunction of the mitochondrial complex 2, lack of driver mutations in KIT and PDGFRA, and a distinctive morphology and natural history. To date, all reported SDH-deficient GISTs have arisen in the stomach...

Approximately 1-5% of breast cancers are attributed to inherited mutations in BRCA1 or BRCA2 and are selectively sensitive to poly(ADP-ribose) polymerase (PARP) inhibitors. In other cancer types, germline and/or somatic mutations in BRCA1 and/or BRCA2 (BRCA1/BRCA2) also confer selective sensitivity to PARP inhibitors. Thus, assays to detect BRCA1/BRCA2-deficient tumors have been sought. Recently, somatic substitution, insertion/deletion and rearrangement patterns, or 'mutational signatures', were associated with BRCA1/BRCA2 dysfunction...

OBJECTIVES: Extensive effort has been made to identify early markers of neurodegeneration as late stages have no chance of treatment. Recently, many experimental models have been used to study hallmarks of neuronal injury. One of them is the model of trimethyltin (TMT)-induced damage associated with cognitive decline, thus called a model of Alzheimer-like disease. OBJECTIVE AND METHODS: Our aim was to study neuronal transmission in hippocampal slices of male Wistar rats affected with a single dose of TMT (7...

BACKGROUND: Premenstrual syndrome (PMS) is a psychological and somatic disorder of unknown aetiology, with symptoms typically including irritability, depression, mood swings, bloating, breast tenderness and sleep disturbances. About 3% to 10% of women who experience these symptoms may also meet criteria for premenstrual dysphoric disorder (PMDD). PMS symptoms recur during the luteal phase of the menstrual cycle and reduce by the end of menstruation. PMS results from ovulation and may be due to ovarian steroid interactions relating to neurotransmitter dysfunction...

Aging is a normal process of living being. It has been reported that multiple cellular changes, including oxidative damage/mitochondrial dysfunction, telomere shortening, inflammation, may accelerate the aging process, leading to cellular senescence. These cellular changes induce age-related human diseases, including Alzheimer's, Parkinson's, multiple sclerosis, amyotrophic lateral sclerosis, cardiovascular, cancer, and skin diseases. Changes in somatic and germ-line DNA and epigenetics are reported to play large roles in accelerating the onset of human diseases...

In 1979, it was observed that parkinsonism could be induced by a toxin inhibiting mitochondrial respiratory complex I. This initiated the long-standing hypothesis that mitochondrial dysfunction may play a key role in the pathogenesis of Parkinson's disease (PD). This hypothesis evolved, with accumulating evidence pointing to complex I dysfunction, which could be caused by environmental or genetic factors. Attention was focused on the mitochondrial DNA, considering the occurrence of mutations, polymorphic haplogroup-specific variants, and defective mitochondrial DNA maintenance with the accumulation of multiple deletions and a reduction of copy number...

Paclitaxel, one of the most commonly used cancer chemotherapeutic drugs, effectively extends the progression-free survival of breast, lung, and ovarian cancer patients. However, paclitaxel and other chemotherapy drugs elicit peripheral nerve fiber dysfunction or degeneration that leads to peripheral neuropathy in a large proportion of cancer patients. Patients receiving chemotherapy also often experience changes in mood, including anxiety and depression. These somatic and affective disorders represent major dose-limiting side effects of chemotherapy...

BACKGROUND: Oral cenesthopathy is the complaint of abnormal oral sensation where no underlying organic cause can be identified. It is also called oral dysesthesia or oral somatic delusion and classified as delusional disorder, somatic type. The patients with oral cenesthopathy show right > left asymmetric regional cerebral blood flow (rCBF) in the broad brain region. However, the studies scrutinizing the rCBF change before and after the successful treatment are still a few so far. CASE: We present 2 cases of oral cenesthopathy, who responded well to aripiprazole...

In the functional medicine model, the word function is aligned with the evolving understanding that disease is an endpoint and function is a process. Function can move both forward and backward. The vector of change in function through time is, in part, determined by the unique interaction of an individual's genome with their environment, diet, and lifestyle. The functional medicine model for health care is concerned less with what we call the dysfunction or disease, and more about the dynamic processes that resulted in the person's dysfunction...
