Physiological stress reactivity and self-harm: A meta-analysis.

Objective: Self-harm is associated with alterations in the psychobiological stress response. Specifically, the reactivity of the autonomic nervous system (ANS) and the endocrine hypothalamic-pituitary-adrenal (HPA) axis may differ in individuals who engage in self-harm. However, evidence in this regard is inconsistent.

Comparison of parental and practitioner's acceptance for dental treatment under general anaesthesia in paediatric patients.

Background: Practitioner's knowledge and parental perspectives on dental general anaesthesia (GA) have been surveyed separately in the past. But in daily routine both need to collaborate for the benefit of the child. The aim of this paper was to compare parental and practitioner's acceptance of GA with special focus on identifying factors which influence their differences in decision making.

Conspiracy beliefs and COVID-19 guideline adherence in adolescent psychiatric outpatients: the predictive role of adverse childhood experiences.

Background: Conspiracy beliefs have become widespread throughout the COVID-19 pandemic. Previous studies have shown that endorsing conspiracy beliefs leads to lower protective guideline adherence (i.e.

Coping styles mediating the relationship between perceived chronic stress and conspiracy beliefs about COVID-19.

As a global health crisis, COVID-19 has led to a rise in overall stress levels. Concurrently, conspiracy beliefs regarding the origin and spread of the disease have become widespread. Engaging in such beliefs can be explained as a form of coping in order to deal with elevated levels of stress.

Maternal attachment representation, the risk of increased depressive symptoms and the influence on children's mental health during the SARS-CoV-2-pandemic.

The social distancing measures and the related closure of education institutions have confronted young families, in particular, with various challenges. Additional risk factors such as an insecure or even unresolved maternal attachment representation may affect mental health of mothers and their children in times of increased stress such as during the ongoing pandemic. We aimed to analyze the interplay between maternal attachment representation and mother's and children's mental health before and during the SARS-CoV-2-pandemic.

'The world somehow stopped moving': impact of the COVID-19 pandemic on adolescent psychiatric outpatients and the implementation of teletherapy.

Background: The COVID-19 pandemic results in disproportional consequences for psychiatric patients. Due to restraints in physical contacts, providers switched from face-to-face contacts to teletherapy, but prior experiences were mostly limited. The study aimed at assessing symptom dynamics, potentially increased adversities and factors influencing a successful transition into teletherapy in adolescent psychiatric outpatients during the COVID-19 pandemic.

Systemic Catecholaminergic Deficiency in Depressed Patients with and without Coronary Artery Disease.

Background: Stress and depression are known to contribute to coronary artery disease (CAD) with catecholamines (CA), altering the balance to a pro- and anti-inflammatory stetting and potentially playing a key role in the underlying pathophysiology. This study aimed to elucidate the impact of social stress on the CA system and inflammation markers in patients suffering from CAD and depression.

Methods: 93 subjects were exposed to the Trier Social Stress Test (TSST).

Reduced caregiving quality measured during the strange situation procedure increases child's autonomic nervous system stress response.

Background: Dysfunctional maternal behavior has been shown to lead to disturbances in infant's regulatory capacities and alterations in vagal reactivity. We aim to investigate the autonomic nervous system (ANS) response of the child during the strange situation procedure (SSP) in relation to the quality of maternal behavior.

Methods: Twelve month after birth, 163 mother-child-dyads were investigated during the SSP.

Casein kinase 1 delta (CK1delta) interacts with the SNARE associated protein snapin.

In this study we identified snapin as an interaction partner of the CK1 isoform delta (CK1delta) in the yeast two-hybrid system and localized the interacting domains of both proteins. The interaction of CK1delta with snapin was confirmed by co-immunoprecipitation. Snapin was phosphorylated by CK1delta in vitro.

The bioactive lipid sphingosylphosphorylcholine induces differentiation of mouse embryonic stem cells and human promyelocytic leukaemia cells.

Sphingosylphosphorylcholine (SPC) is the major component of high-density lipoproteins (HDL) in blood plasma. The bioactive lipid acts mainly via G protein coupled receptors (GPCRs). Similar to ligands of other GPCRs, SPC has multiple biological roles including the regulation of proliferation, migration, angiogenesis, wound healing and heart rate.

Role of the regulatory domain of protein kinase D2 in phorbol ester binding, catalytic activity, and nucleocytoplasmic shuttling.

Protein kinase D2 (PKD2) belongs to the PKD family of serine/threonine kinases that is activated by phorbol esters and G protein-coupled receptors (GPCRs). Its C-terminal regulatory domain comprises two cysteine-rich domains (C1a/C1b) followed by a pleckstrin homology (PH) domain. Here, we examined the role of the regulatory domain in PKD2 phorbol ester binding, catalytic activity, and subcellular localization: The PH domain is a negative regulator of kinase activity.

Interaction of casein kinase 1 delta (CK1 delta) with the light chain LC2 of microtubule associated protein 1A (MAP1A).

CK1delta, a member of the casein kinase 1 family of serine/threonine specific kinases, has been shown to be involved in the regulation of microtubule dynamics. We have now identified a 176 aa fragment of the light chain LC2 of MAP1A (termed LC2-P16) specifically interacting with CK1delta. Two CK1delta interacting domains of LC2 were identified, located between aa 2629 and 2753 close to aa 2683 and between aa 2712 and 2805 of LC2.

Gastrointestinal cancer: towards a tailored tumour therapy.

Major progress has been made in the treatment of metastatic colorectal cancer, but conventional chemotherapy is unlikely to lead to a major breakthrough in the treatment of gastrointestinal tumours. Prognosticators, novel means of early diagnosis of cancer which at the same time indicate prognosis, as well as novel, tumour-specific therapeutic strategies, are urgently needed. There is an increasing amount of promising data from array technology and functional proteomics suggesting that this goal could be achieved in the near future.

Novel protein kinases in pancreatic cell growth and cancer.

The network of enzymes that contribute to the signal transduction of extracellular factors in pancreatic cancer is ever increasing. The classical Raf-MEK-ERK signaling cascade plays a crucial role in the regulation of apoptosis, proliferation, and metastasis of pancreatic cancer. Phosphatidylinositide-3-kinase also contributes to growth and prevents apoptosis in pancreatic cancer cells, acting in part via its downstream targets, PKB/AKT and the FRAP/p70s6k signaling complex.

Mechanism of activation of protein kinase D2(PKD2) by the CCK(B)/gastrin receptor.

Recently, we cloned a novel serine/threonine kinase termed protein kinase D2 (PKD2). PKD2 can be activated by phorbol esters both in vivo and in vitro but also by gastrin via the cholecystokinin/CCK(B) receptor in human gastric cancer cells stably transfected with the CCK(B)/gastrin receptor (AGS-B cells). Here we identify the mechanisms of gastrin-induced PKD2 activation in AGS-B cells.

The aim of this study was to determine the zinc status in relation to immunological parameters and disease stage in 79 HIV-1 seropositive patients. The median serum level of zinc was within normal limits (12.

Antitumor activity of new organometallic compounds in human ovarian cancer cell lines and comparison to platin derivatives.

Cisplatin, Carboplatin and new compounds such as Paclitaxel and Docetaxel are effective drugs in the treatment of ovarian cancer. Multidrug resistance however remains an issue in ovarian cancer. The search for new effective drugs will remain of the highest priority in the field of cancer research.

Morphology and blood supply of the iliac crest applied to jaw reconstruction.

The aim of this study was to improve vessel and nerve security and the harvesting procedure of the iliac crest in the microvascular reconstruction of the upper and lower jaw by iliac crest flap in cases of tumour invasion or trauma. The critical points for the surgeon in harvesting the iliac crest are the course of the deep circumflex iliac artery and lateral cutaneous nerve of the thigh in relation to the iliac crest and the position of their subsequent ramifications. Bilateral anatomical preparations of the iliac bone (total 90 dissections) were examined in 45 formalin preserved cadavers (21 male, 24 female) with the course of the vessel and nerve supply being mapped.

Deoxycholate and cholate modulate the source of cholesterol substrate for bile acid synthesis in the rat.

In the current study, the role of the supply of preformed and newly synthesized cholesterol for the feedback control of the synthesis of different bile acids and the secretion of biliary cholesterol was investigated. To define these cholesterol fluxes and the possibility of a different modulation by bile acids with different suppressive capacities, a continuous labeling with tritiated water was used in rats with an extracorporeal bile duct receiving intraduodenal infusions of taurocholate or taurocholate plus deoxycholate. After bile acid pool depletion (6 to 9 hours) total muricholate, cholate, and chenodeoxycholate synthesis was variably increased (24% to 93%) during an infusion of 304 mumol taurocholate/kg per hour.

Biliary cholesterol secretion and bile acid formation in the hamster: the role of newly synthesized cholesterol.

In order to define the source of cholesterol for bile acid synthesis and biliary cholesterol, hamsters with an extracorporeal bile duct received an intraperitoneal bolus of [3H]water labeling newly synthesized cholesterol. Thereafter the enterohepatic circulation was interrupted and a nutrient solution was infused during the experimental period of 78 h. In a separate group, pravastatin was administered (54-78 h) to allow discrimination of 3H-labeled cholesterol recycling from plasma and newly synthesized hepatic cholesterol late during the experiment.
