BACKGROUND: Salmonella typhimurium is the main cause of gastrointestinal illness in humans, and treatment options are decreasing because drug-resistant strains have emerged. OBJECTIVE: The objective of this study was to use computational drug repurposing to identify a novel candidate with an effective mechanism of action to circumvent the drug resistance. METHODS: We used the Mantra 2.0 database to initially screen drug candidates that share similar gene expression profiles to those of quinolones...

: The premise of parent-centred programmes for parents of anxious children is to educate and train caregivers in the sustainable implementation of cognitive behaviour therapy (CBT) in the home. The existing operationalization of parent involvement, however, does not address the systemic, parent or child factors that could influence this process. The qualitative approach of grounded theory was employed to examine patterns of action and interaction involved in the complex process of carrying out CBT with one's child in one's home...

OBJECTIVE: Curcumin, the golden spice from Indian saffron, has shown chemoprotective action against many types of cancer including breast cancer. However, poor oral bioavailability is the major hurdle in its clinical application. In the recent years, self-nanoemulsifying drug delivery system (SNEDDS) has emerged as a promising tool to improve the oral absorption and enhancing the bioavailability of poorly water-soluble drugs. In this context, complexation with lipid carriers like phospholipid has also shown the tremendous potential to improve the solubility and therapeutic efficacy of certain drugs with poor oral bioavailability...

An integrative-psychodynamic theory of criticism in self and relationships is presented (Shahar, 2015). My theoretical starting point is the tension between Authenticity (A; our inherited potential, tantamount to Winnicott's True Self) and Self-Knowledge (SK; what we [think] we know about ourselves). Self-criticism, a formidable dimension of vulnerability to a wide array of psychopathologies, is construed as a distorted form of self-knowledge, reducing internal confusion at the expense of widening the gap between A and SK...

Magnetic resonance imaging (MRI) is one of the most commonly used tomography techniques in medical diagnosis due to the non-invasive character, the high spatial resolution and the possibility of soft tissue imaging. Contrast agents, such as gadolinium complexes and superparamagnetic iron oxides, are administered to spotlight certain organs and their pathologies. Many new models have been proposed that reduce side effects and required doses of these already clinically approved contrast agents. These new candidates often possess additional functionalities, e...

Depressive disorders are heterogeneous diseases, and the complexity of symptoms has led to the formulation of several aethiopathological hypotheses. This heterogeneity may account for the following open issues about antidepressant therapy: (i) antidepressants show a time lag between pharmacological effects, within hours from acute drug administration, and therapeutic effects, within two-four weeks of subchronic treatment; (ii) this latency interval is critical for the patient because of the possible further mood worsening that may result in suicide attempts for the seemingly ineffective therapy and for the apparent adverse effects; (iii) and only 60-70 % of treated patients successfully respond to therapy...

According to embodied simulation theory, understanding other people's emotions is fostered by facial mimicry. However, studies assessing the effect of facial mimicry on the recognition of emotion are still controversial. In Parkinson's disease (PD), one of the most distinctive clinical features is facial amimia, a reduction in facial expressiveness, but patients also show emotional disturbances. The present study used the pathological model of PD to examine the role of facial mimicry on emotion recognition by investigating EMG responses in PD patients during a facial emotion recognition task (anger, joy, neutral)...

OBJECTIVE: A prominent theory of depression focusses on neural plasticity and stress as central issues in seeking to develop a pattern of identifiable biological markers for the depressive disorders. Relative neglect, however, of clinical factors in that theory limits the uncovering of markers and opens to question their methodological approach. A conflicting theory, the 'opposed neurobehavioral states', based on dimensional analysis of monoamine neurotransmitter systems and behavioural factors is presented...

Depression is a common disease influencing patients' quality of life, whose etiology involves complex interactions of environmental, genetic and immunological factors. The latter factors include proinflammatory activation of monocytes and macrophages and increased serum levels of proinflammatory cytokines, altogether formulated as the "macrophage theory of depression". Our current review summarizes the impact of the most commonly used antidepressant drugs on the immune response with special emphasis on the role of macrophages in the clinically observed effects...

The gastrointestinal (GI) tract is an electrically excitable organ system containing multiple cell types, which coordinate electrical activity propagating through this tract. Disruption in its normal electrophysiology is observed in a number of GI motility disorders. However, this is not well characterized and the field of GI electrophysiology is much less developed compared to the cardiac field. The aim of this article is to use the established knowledge of cardiac electrophysiology to shed light on the mechanisms of electrical activation and propagation along the GI tract, and how abnormalities in these processes lead to motility disorders and suggest better treatment options based on this improved understanding...

Polycystic ovary syndrome (PCOS) is a common condition affecting women of reproductive age. This disorder is characterized by hyperandrogenism and anovulation and is frequently associated with comorbidities such as infertility, metabolic syndrome, type 2 diabetes, and cardiovascular risk factors. Although the causes of PCOS are unknown, this review focuses on the most accepted theory involving insulin action but will also elaborate on a novel concept: the role of lipotoxicity in the development of androgen overproduction, in addition to its known role in insulin resistance...

Hepatic cytochrome P450 levels are down-regulated during inflammatory disease states, which can cause changes in downstream drug metabolism and hepatotoxicity. Long-term, we seek sufficient new insight into P450-regulating mechanisms to correctly anticipate how an individual's P450 expressions will respond when health and/or therapeutic interventions change. To date, improving explanatory mechanistic insight relies on knowledge gleaned from in vitro, in vivo, and clinical experiments augmented by case reports...

In recent years, computerized and non-computerized cognitive remediation programs have been designed for both individual and group settings. We believe, however, that a common misconception lies in considering the efficiency of a cognitive remediation therapy as resulting from the sole use of a computer. This omits that metacognitive skills need also to be trained throughout the remediation phase. RECOS is a theory-based therapeutic approach designed to promote the transfer of cognitive skills to functional improvements...

RATIONALE: The neurotrophin hypothesis of major depressive disorder (MDD) postulates that this illness results from aberrant neurogenesis in brain regions that regulates emotion and memory. Notwithstanding this theory has primarily implicated BDNF in the neurobiology of MDD. Recent evidence suggests that other trophic factors namely GDNF, VEGF and IGF-1 may also be involved. PURPOSE: The present review aimed to critically summarize evidence regarding changes in GDNF, IGF-1 and VEGF in individuals with MDD compared to healthy controls...

Treatment options for disease recurrence of women treated for locally advanced and advanced cervical cancer are very limited-largely palliative chemotherapy. The low efficacy of the currently available drugs raises the need for new targeted agents. Poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitors (PARPi) have emerged as a promising class of chemotherapeutic agents in cancers associated with defects in DNA repair. Their therapeutic potential in cervical cancer is currently being evaluated in 3 ongoing clinical trials...

INTRODUCTION: Licenced oral pharmacotherapies for overactive bladder (OAB) act on muscarinic receptors or β3-adrenoceptors. The search for new drugs to treat OAB that have novel mechanisms of action is very active, with the aim of discovering more effective and/or better tolerated agents. METHODS: A literature review of the most frequently used pharmacological methods for the preclinical assessment of new agents aimed at treating OAB, such as isolated organ technique, electrophysiological techniques, radioligand binding assay, and animal models, was carried out...

OBJECTIVE: To find and analyze descriptions in ancient Greek and Roman literature that reveal what was known at the time about seasickness. METHODS: A systematic search was made in the original literature beginning in the Greek period with Homer in ca 800 bc and extending up to Aetios Amidenos in the late Roman period in ca 600 ad. RESULTS: Rough seas and unpleasant odors were recognized as the major triggers; susceptibility was greater in persons not adapted to sea travel, of a labile mental state, or with anxiety; nausea, emesis, vertigo, anorexia, faintness, apathy, headache, and impending doom were frequently reported symptoms...

In the light of historical and modern criticism of the discipline of psychiatry and psychotherapy as a medical subspecialty, this paper deals with aspects of the theory of medicine as postulated by the physician and philosopher Wolfgang Wieland. According to his contributions medicine is a practical science aiming at establishing rational action. Central to this model is a diagnosis, which helps to subsume individual cases under general principles from which essential therapeutic options can be derived. Hence, psychiatry and psychotherapy become a medical subspecialty by adopting the basic model of medical reasoning and action as described by Wieland...

Inflammatory bowel diseases (IBD), including ulcerative colitis and Crohn's disease are chronic, life-long, and relapsing diseases of the gastrointestinal tract. Currently, there are no complete cure possibilities, but combined pharmacological and nutritional therapy may induce remission of the disease. Malnutrition and specific nutritional deficiencies are frequent among IBD patients, so the majority of them need nutritional treatment, which not only improves the state of nutrition of the patients but has strong anti-inflammatory activity as well...
