Abstract
OBJECTIVE The purpose of this investigation was to identify distinctive clinical correlates of psychotic major depression (PMD) as compared with non-psychotic major depression (NPMD) in a large cohort of Korean patients with major depressive disorder (MDD). METHODS We recruited 966 MDD patients of age over 18 years from the Clinical Research Center for Depression of South Korea (CRESCEND) study. Diagnoses of PMD (n=24) and NPMD (n=942) were made with the DSM-IV definitions and confirmed with SCID. Psychometric scales were used to assess overall psychiatric symptoms (BPRS), depression (HAMD), anxiety (HAMA), global severity (CGI-S), suicidal ideation (SSI-Beck), functioning (SOFAS), and quality of life (WHOQOL-BREF). Using independent t-tests and χ(2) tests, we compared clinical characteristics of patients with PMD and NPMD. A binary logistic regression model was constructed to identify factors independently associated with increased likelihood of PMD. RESULTS PMD subjects were characterized by a higher rate of inpatient enrollment, and higher scores on many items on BPRS (somatic concern, anxiety, emotional withdrawal, guilt feelings, tension, depression, suspiciousness, hallucination, motor retardation, blunted affect and excitement) global severity (CGI-s), and suicidal ideation (SSI-Beck). The explanatory factor model revealed that high levels of tension, excitement, and suicidal ideation were associated with increased likelihood of PMD. CONCLUSION Our findings partly support the view that PMD has its own distinctive clinical manifestation and course, and may be considered a diagnostic entity separate from NPMD.

Abstract
The aim of the current study was to identify personality traits associated with suicidal behavior in patients with depression. Of the 1183 patients screened for an observational cohort study of depression, 334 (28.2%) who completed the Temperament and Character Inventory (TCI) were included in these analyses. To minimize the effect of current mood state, the TCI was performed 12 weeks after initiation of treatment, and we adjusted for the severity of depression. Of the 344 participants, 59 had a lifetime history of at least one suicide attempt, 37 had a lifetime history of multiple suicide attempts, and 5 attempted suicide during the 12-week study period. At baseline, patients with a lifetime history of at least one suicide attempt, a lifetime history of multiple suicide attempts, and a suicide attempt during the study period expressed more serious current suicidal ideation than did those without such a history, despite the absence of differences among the groups in the severity of depressive and anxiety symptoms. Of the seven personality scales of the TCI, lower scores on the self-directedness scale of the character dimension were associated with a history of at least one suicide attempt (OR [95% CI], 0.91 [0.87-0.96]; p<0.001), a history of multiple suicide attempts (0.91 [0.86-0.97]; p=0.003), and suicide attempts during study period (0.80 [0.69-0.94]; p=0.006). These findings suggest that depressed patients with a history of suicidal behavior differ from non-attempters with regard to personality traits, especially the character dimension of self-directedness. It is noteworthy that this result emerged after controlling for the effect of current mood state.

Abstract
AIM Several systematic reviews (SRs) of acupuncture for surgical conditions have recently been published with sometimes contradicting results. The aim of this overview was to summarise recent SRs of acupuncture for surgical conditions. METHOD Thirteen electronic databases were searched for relevant reviews published since 2000. Data were extracted by two independent reviewers according to predefined criteria. RESULTS Twelve SRs met our inclusion criteria. They related to the prevention or treatment of postoperative nausea and vomiting as well as to surgical or postoperative pain. Their results were far from uniform, and several caveats need to be considered. CONCLUSION The evidence is insufficient to suggest that acupuncture is an effective intervention in surgical settings. More rigorous research seems warranted. This protocol was registered with PROSPERO database (registration number: CRD42013004817).

Abstract
This paper aims to introduce, summarize, and emphasize the importance of the 'Evidence-Based, Pharmacological Treatment Guideline for Depression in Korea, Revised Edition'. The guideline broadly covers most aspects of the pharmacological treatment of patients in Korea diagnosed with moderate to severe major depression according to the DSM-IV TR. The guideline establishment process involved determining and answering a number of key questions, searching and selecting publications, evaluating recommendations, preparing guideline drafts, undergoing external expert reviews, and obtaining approval. A guideline adaptation process was conducted for the revised edition. The guideline strongly recommends pharmacological treatment considered appropriate to the current clinical situation in Korea, and should be considered helpful when selecting the appropriate pharmacological treatment of patients diagnosed with major depressive disorder. Therefore, the wide distribution of this guideline is recommended.

Abstract
Hot pepper (Capsicum annuum), one of the oldest domesticated crops in the Americas, is the most widely grown spice crop in the world. We report whole-genome sequencing and assembly of the hot pepper (Mexican landrace of Capsicum annuum cv. CM334) at 186.6× coverage. We also report resequencing of two cultivated peppers and de novo sequencing of the wild species Capsicum chinense. The genome size of the hot pepper was approximately fourfold larger than that of its close relative tomato, and the genome showed an accumulation of Gypsy and Caulimoviridae family elements. Integrative genomic and transcriptomic analyses suggested that change in gene expression and neofunctionalization of capsaicin synthase have shaped capsaicinoid biosynthesis. We found differential molecular patterns of ripening regulators and ethylene synthesis in hot pepper and tomato. The reference genome will serve as a platform for improving the nutritional and medicinal values of Capsicum species.

Abstract
Nutritional conditions during the intrauterine stage are an important developmental programming factor that can affect the growth and metabolic status during foetal development and permanently alter the phenotypes of newborn offspring and adults. This study was performed to examine the effects of intrauterine catch-up growth (IUCG) on food intake, post-natal body growth and the metabolic status of offspring and growing rats. Control pregnant rats were fed ad libitum during the entire gestation period. For the IUCG regimen, pregnant rats were fed 50% of the food of the controls from pregnancy days 4 through 11 (8 days), followed by ad libitum feeding from pregnancy days 12 through parturition. The birth weight of offspring was not affected by the IUCG regimen. At weaning, offspring from each treatment group were assigned to two groups and given either a normal diet or high-fat diet (HFD) for 12 weeks until 103 days of age. In the normal diet group, the IUCG offspring showed a 9.0% increase (P < 0.05) in total food intake, were 11.2% heavier (p < 0.05) at 103 days of age and had an 11.0% greater (p < 0.05) daily weight gain compared with control offspring. The IUCG regimen did not affect body glucose and lipid metabolism. After exposure to the HFD, the IUCG regimen has not exacerbated metabolic disorders. In conclusion, our findings suggest that the IUCG nutritional regimen during pregnancy can increase the food intake and post-natal body growth of offspring without inducing metabolic disorders such as obesity and insulin resistance. The IUCG nutritional regimen might be used to improve the food intake and post-natal body growth of domestic animals.

Abstract
BACKGROUND The uncertainty over the true morphological changes in brains with major depressive disorder (MDD) underlines the necessity of comprehensive studies with multimodal structural brain imaging analyses. This study aimed to evaluate the differences in cortical thickness, cortical and subcortical volume, and white matter integrity between first episode, medication-naïve MDD patients and healthy controls. METHODS Subjects with their first episode of MDD whose illness duration had not exceeded 6 months (n=20) were enrolled in this study and were compared to age-, sex-, and education level-matched healthy controls (n=22). All participants were subjected to T1-weighted structural magnetic resonance imaging (MRI). We used an automated procedure of FreeSurfer and Tract-based spatial statistics (TBSS) to analyze differences in cortical thickness, cortical and subcortical volume, and white matter integrity between two groups. RESULTS The patients with first episode MDD exhibited significantly reduced cortical volume in the caudal anterior cingulate gyrus (P<0.0015) compared to healthy controls. We also observed altered white matter integrity in the body of the corpus callosum (P<0.01), reduced cortical volume of the caudal middle frontal gyrus and medial orbitofrontal gyrus, and enlarged hippocampal volume in the first episode MDD patients. LIMITATIONS We relied on a relatively small sample size and cortical volume reduction in several brain regions was not replicated in the analysis of cortical thickness. CONCLUSIONS Using multimodal imaging analyses on medication-naïve first episode MDD patients, we demonstrated fundamental structural alteration of brain gray and white matter, such as reduced cortical volume of the caudal ACC and white matter integrity in the body of the corpus callosum.

Abstract
BACKGROUND The appropriate length of time for patients who visit clinics with significant suicidal ideation to be closely monitored is a critical issue for clinicians. We evaluated the course of suicidal ideation and associated factors for persistent suicidality in patients who entered treatment for depression with significant suicidal ideation. METHODS A total of 565 patients who had both moderate to severe depression (Hamilton Depression Rating Scale (HAMD) score ≥14) and significant suicidal ideation (Beck Scale for Suicide Ideation (SSI-B) score ≥6) were recruited from 18 hospitals in South Korea. Participants were assessed using the SSI-B, HAMD, Hamilton Anxiety Rating Scale, and Clinical Global Impression Scale-severity during a 12-week naturalistic treatment with antidepressant intervention. Participants were classified into resolved suicidality or persistent suicidality groups according to whether their suicidal ideation improved to SSI-B scores <6 and were sustained for 12 weeks. RESULTS During the 12-week treatment, 206 (36.4%) patients were classified in the resolved suicidality group. Persistent suicidality was associated with intervention with SSRIs, higher SSI-B baseline score, and no HAMD or HAMA remission. The proportions of participants who had persistent suicidal ideation even with HAMD remission or response were 0.25 and 0.34, respectively. LIMITATIONS This study was observational, and the treatment modality was naturalistic. CONCLUSIONS A considerable number of patients had persistent suicidal ideation despite 12 weeks of antidepressant treatment. Close monitoring for suicidal ideation may be needed beyond the initial weeks of treatment and even after a response to antidepressants is observed.

Abstract
Background DNA methylation in the promoter region of the glucocorticoid receptor gene (NR3C1) is closely associated with childhood adversity and suicide. However, few studies have examined NR3C1 methylation in relation to major depressive disorder (MDD) and hippocampal subfield volumes. We investigated the possible association between NR3C1 methylation and structural brain alterations in MDD in comparison with healthy controls. Methods We compared the degree of NR3C1 promoter methylation in the peripheral blood of non-psychotic outpatients with MDD and that of healthy controls. Correlations among NR3C1 promoter methylation, structural abnormalities in hippocampal subfield volumes and whole-brain cortical thickness, and clinical variables were also analyzed. Results In total, 117 participants (45 with MDD and 72 healthy controls) were recruited. Patients with MDD had significantly lower methylation than healthy controls at 2 CpG sites. In MDD, methylations had positive correlations with the bilateral cornu ammonis (CA) 2–3 and CA4-dentate gyrus (DG) subfields. However, in healthy controls, methylations had positive correlation with the subiculum and presubiculum. There were no differences in total and subfield volumes of the hippocampus between patients with MDD and healthy controls. Compared with healthy controls, patients with MDD had a significantly thinner cortex in the left rostromiddle frontal, right lateral orbitofrontal, and right pars triangularis areas. Conclusions Lower methylation in the NR3C1 promoter, which might have compensatory effects relating to CA2-3 and CA4-DG, is a distinct epigenetic characteristic in non-psychotic outpatients with MDD. Future studies with a longitudinal design and a comprehensive neurobiological approach are warranted in order to elucidate the effects of NR3C1 methylation.

Abstract
OBJECTIVE To investigate whether the anxious depression defined as depression with clinically significant anxiety but not comorbid anxiety disorder predicts poor outcomes of depression treatment in naturalistic clinical setting. METHOD From nationwide sample of 18 hospitals, 674 patients with moderate to severe depression who completed the DSM-IV-based Structured Clinical Interview (SCID) were recruited. Anxious depression was defined as not having comorbid anxiety disorder by SCID and having a Hamilton Rating Scale for Anxiety (HAM-A) total score ≥ 20. Participants were classified into three groups: anxious depression (N=259), non-anxious depression (N=351), or comorbid anxiety disorder (N=64). Rates of and time to remission and response and changes in scale scores were compared between these groups during 12 weeks treatment with antidepressant interventions freely determined by clinicians. RESULTS No significant differences were observed in the Hamilton Rating Scale for Depression (HAM-D) remission rate and the time to achieve HAM-D remission between anxious and non-anxious depression after adjustment for variables is not equally distributed at baseline. There were also no significant differences in HAM-D and HAM-A response rate and time to responses between two groups. Patients with comorbid anxiety disorder showed less improvement on HAM-D and HAM-A score than did those with anxious depression despite similar baseline symptom severity. LIMITATION This study was observational, and the treatment modality was naturalistic. CONCLUSIONS Anxious depression did not predict worse outcome to antidepressants treatment. This finding might result from exclusion of comorbid anxiety disorder from anxious depression population and allowance of broad treatment modality.

Abstract
Although pharmacological treatment constitutes the main therapeutic approach for depression, non-pharmacological treatments (self-care or psychotherapeutic approach) are usually regarded as more essential therapeutic approaches in clinical practice. However, there have been few clinical practice guidelines concerning self-care or psychotherapy in the management of depression. This study introduces the 'Evidence-Based, Non-Pharmacological Treatment Guideline for Depression in Korea.' For the first time, a guideline was developed for non-pharmacological treatments for Korean adults with mild-to-moderate depression. The guideline development process consisted of establishing several key questions related to non-pharmacologic treatments of depression, searching the literature for studies which answer these questions, assessing the evidence level of each selected study, drawing up draft recommendation, and peer review. The Scottish Intercollegiate Guidelines Network grading system was used to evaluate the quality of evidence. As a result of this process, the guideline recommends exercise therapy, bibliotherapy, cognitive behavior therapy, short-term psychodynamic supportive psychotherapy, and interpersonal psychotherapy as the non-pharmacological treatments for adult patients with mild-to-moderate depression in Korea. Hence, it is necessary to develop specific methodologies for several non-pharmacological treatment for Korean adults with depression.

Abstract
Major depressive disorder is prevalent worldwide, and only about half of those affected will experience no further episodes or symptoms. Additionally, depressive symptoms can be challenging to identify, with many patients going undiagnosed despite a wide variety of available treatment options. Antidepressants are the cornerstone of depression treatment; however, a large number of factors must be considered in selecting the treatment best suited to the individual. To help support physicians in this process, international and national treatment guidelines have been developed. This review evaluates the current use of antidepressant treatment for major depressive disorder in six Asian countries (China, Korea, Malaysia, Philippines, Taiwan, and Thailand). No remarkable differences were noted between Asian and international treatment guidelines or among those from within Asia as these are adapted from western guidelines, although there were some local variations. Importantly, a shortage of evidence-based information at a country level is the primary problem in developing guidelines appropriate for Asia, so most of the guidelines are consensus opinions derived from western research data utilized in western guidelines. Treatment guidelines need to evolve from being consensus based to evidence based when evidence is available, taking into consideration cost/effectiveness or cost/benefit with an evidence-based approach that more accurately reflects clinical experience as well as the attributes of each antidepressant. In everyday practice, physicians must tailor their treatment to the patient's clinical needs while considering associated external factors; better tools are needed to help them reach the best possible prescribing decisions which are of maximum benefit to patients.

Abstract
OBJECTIVE To investigate the prevalence, clinical manifestations, and clinical correlates of insomnia in a large cohort of Korean patients with depressive disorders. METHODS We recruited 944 patients with depressive disorders from the Clinical Research Center for Depression of South Korea (CRESCEND) study. Psychometric scales were used to assess depression (HAMD), anxiety (HAMA), psychotic symptoms (BPRS), global severity (CGI-S), and functioning (SOFAS). Insomnia levels were determined by adding the scores for all items on the HAMD insomnia subscale. The clinical characteristics of the patients with 'low insomnia' (summed score ≤3 on the HAMD subscale) and 'high insomnia' (score ≥4) were compared using statistical analyses. A logistic regression model was constructed to identify factors associated with 'high insomnia' status. RESULTS Symptoms of insomnia were present in 93% of patients, while simultaneous early, middle, and late insomnia affected 64.1%. The high insomnia patients were characterized by significantly greater age, higher symptom levels (including core, gastrointestinal somatic and anxiety symptoms, and suicidal ideation), higher global severity and incidence of physical disorders, and greater insight. Explanatory factors of 'high insomnia' status were older age, higher gastrointestinal somatic and anxiety symptom levels, higher global severity, and greater insight. CONCLUSION In clinical psychiatry, insomnia has been significantly underdiagnosed and undertreated. It affects most patients with depressive disorders, and is indicative of the global severity of depression. Active efforts to diagnose and treat insomnia in patients with depressive disorders should be strongly encouraged. Further research is needed to improve the diagnosis and treatment of insomnia in depressive patients.

Abstract
OBJECTIVE The impact of childhood adversity persists across the life course. This study aimed to investigate the associations of childhood adversity with the course, suicidality, and treatment outcomes of depressive disorders. METHOD A total of 919 people with depressive disorders were recruited. Childhood adversities (≤12 years old) were ascertained using a checklist, in sexual abuse, physical abuse by parents, and separation of parents. Various assessment scales were administered at baseline and over 12 weeks of antidepressants treatment. RESULTS All three forms of childhood adversity were associated with an increased likelihood of experiencing more current stressful events. Scores on the Beck Depression Inventory and Hamilton Anxiety Rating Scale were significantly higher in participants with a history of sexual abuse. Scores on the Beck Depression Inventory, Hamilton Depression Rating Scale, and Perceived Stress Scale were significantly higher, and scores on the WHO Quality of life instrument were significantly lower in participants with a history of physical abuse by parents. They were more likely to receive augmentation and combination treatment after the initial antidepressant treatment, whereas overall response rates to treatment did not differ. Scores on the Beck Scale for suicide ideation were significantly higher after treatment and/or at baseline in patients with sexual or physical abuse. Physical illness was more prevalent in individuals with physical abuse by parents or separation of parents. CONCLUSIONS Depressive patients with a history of childhood adversities had more severe and chronic forms of depression with high suicidality. More intensive treatment with particular clinical attention is indicated for this special population.

Abstract
OBJECTIVE Cytochrome P450 (CYP) enzymatic activity, which is influenced by CYP genetic polymorphism, is known to affect the inter-individual variation in the efficacy and tolerability of antidepressants in major depressive disorder (MDD). Escitalopram is metabolized by CYP2D6, and recent studies have reported a correlation between clinical outcomes and CYP2D6 genetic polymorphism. The purpose of this study was to determine the relationship between the CYP2D6 P34S polymorphism (C188T, rs1065852) and the efficacy of escitalopram treatment in Korean patients with MDD. METHODS A total of 94 patients diagnosed with MDD were recruited for the study and their symptoms were evaluated using the 21-item Hamilton Depression Rating scale (HAMD-21). The association between the CYP2D6 P34S polymorphism and the clinical outcomes (remission and response) was investigated after 1, 2, 4, 8, and 12 weeks of escitalopram treatment using multiple logistic regression analysis and χ(2) test. RESULTS The proportion of P allele carriers (PP, PS) in remission status was greater than that of S allele homozygotes (SS) after 8 and 12 weeks of escitalopram treatment. Similarly, P allele carriers exhibited a greater treatment response after 8 and 12 weeks of escitalopram treatment than S allele homozygotes. CONCLUSION Our results suggest that the P allele of the CYP2D6 P34S polymorphism is a favorable factor in escitalopram treatment for MDD, and that the CYP2D6 P34S polymorphism may be a good genetic marker for predicting escitalopram treatment outcomes.

Abstract
BACKGROUND Patients with panic disorder with agoraphobia (PDA) have clinical symptoms such as the fear of being outside or of open spaces from which escape would be difficult. Although recent neurobiological studies have suggested that fear conditioning and extinction are associated with PDA, no study has examined the possible structural abnormalities in patients with PDA. METHODS This preliminary study compares the gray matter volume among patients with PDA, those with panic disorder without agoraphobia (PDW), and healthy controls (HC) using high-resolution 3.0 T magnetic resonance imaging (MRI) with voxel-based morphometry (VBM). RESULTS Compared with HC, patients with PDA showed decreased gray matter volume in their left medial orbitofrontal gyrus. However, differences were not found in the gray matter volumes of patients with PDW and whole panic disorder compared with HC. CONCLUSIONS These findings suggest that the phobic avoidance found in patients with PDA arise from abnormalities in the medial orbitofrontal cortex, which plays an important role in fear extinction. Future studies should investigate the neuroanatomical substrates of PDA and distinguish them from those of PDW.

No Association between Serotonin Receptor 2C-759C/T Polymorphism and Weight Change or Treatment Response to Mirtazapine in Korean Depressive Patients. Psychiatry Investig 2013; 10:190-5. [PMID: 23798968 PMCID: PMC3687054 DOI: 10.4306/pi.2013.10.2.190] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2010] [Revised: 04/28/2011] [Accepted: 01/28/2013] [Indexed: 01/21/2023] Open
Abstract
OBJECTIVE Activation of one or more serotonin (5-HT) receptors may play a role in mediating the antidepressant effects of serotonergic antidepressants. The serotonin 2C (5HT 2C) receptor is known to be associated with antidepressant action and weight gain. We sought to determine whether the 5-HTR 2C receptor -759C/T polymorphism was associated with weight gain and treatment response to mirtazapine in major depressive disorder (MDD) patients. METHODS The 5-HT 2C receptor -759C/T polymorphism was analyzed in 323 MDD patients. All patients were evaluated using the 21-item Hamilton Depression Rating Scale at the beginning of the study and at 1, 2, 4, and 8 weeks of mirtazapine treatment. RESULTS There was no significant difference in the 5-HT 2C receptor -759C/T genotype distribution between responder and non-responder groups. The 5-HT 2C receptor -759C/T polymorphism was not associated with weight change over time after mirtazapine administration. CONCLUSION The 5-HT 2C receptor -759C/T polymorphism does not appear to be a predictor of treatment response to mirtazapine. This polymorphism was not associated with weight change after 8 weeks of mirtazapine treatment. Further investigation on other polymorphisms of the 5-HT 2C gene is required to determine whether the 5-HT 2C gene influences treatment response and weight change after mirtazapine administration in patients with major depressive disorder.

Abstract
AIM To compare the reliability of the conventional ultrasonography grading system for hydronephrosis as suggested by the Society for Fetal Urology (SFU) in 1993 and that developed by Onen in 2007. MATERIALS AND METHODS One hundred and eighty kidneys in 90 paediatric patients were assessed by four radiologists using each of the two grading systems twice. The SFU system was graded 0-4 (0 = no hydronephrosis; 1 = visualized only renal pelvis; 2 = plus a few caliceal dilatation; 3 = all calyceal dilatation; 4 = plus parenchymal thinning). The Onen system was graded 0-4 (0 = no hydronephrosis; 1 = only renal pelvic dilatation; 2 = plus caliceal dilatation; 3 = plus <50% renal parenchymal loss; 4 = plus >50% renal parenchymal loss). Cohen's kappa statistic was used to estimate intra- and interobserver agreement. The weighted least-squares approach was used to compare the intra-observer agreement, and bootstrapping was used to compare the interobserver agreement between the two systems. RESULTS Intra-observer agreement was substantial to almost perfect in both the SFU (κ 0.79-0.95) and the Onen (κ 0.66-0.97) grading system without difference. The overall interobserver agreement was substantial in both the SFU (κ 0.61-0.68) and the Onen (κ 0.66-0.76) grading system. However, interobserver agreement was fair to moderate for SFU grades 1 and 2 and Onen grades 2 and 3. CONCLUSION Both the SFU and Onen grading system are reliable with good intra- and interobserver agreement. However, decreased interobserver agreement was demonstrated for SFU grades 1 and 2 and Onen grades 2 and 3.

Association between serotonin transporter-linked polymorphic region and escitalopram antidepressant treatment response in Korean patients with major depressive disorder.

Abstract
OBJECTIVE Various studies have shown that short (s)/long (l) polymorphisms of the serotonin transporter-linked polymorphic region (5-HTTLPR) might predict treatment outcome to selective serotonin reuptake inhibitors. The purpose of this study was to evaluate the association between 5-HTTLPR and clinical response to escitalopram treatment in Korean subjects with major depressive disorder. METHODS One hundred and fifteen Korean patients diagnosed with major depressive disorder were evaluated during 8 weeks of escitalopram treatment at a dose of 5-20 mg/day. Patients were genotyped for 5-HTTLPR using polymerase chain reaction. Clinical symptoms were evaluated by the 21-item Hamilton Depression Rating (HAMD-21) scale during the 8 weeks of treatment. RESULTS Therapeutic response to antidepressant escitalopram was better in s allele carriers (ss, sl) than in l allele homozygotes (ll) at 8 weeks of treatment (OR = 6.24, p = 0.026). The proportion of s allele carriers in responders was higher than that in non-responders (96.6 vs. 85.7%). The percentile decline in HAMD-21 in s allele carriers (59.86 ± 3.23%) was larger than that in HAMD-21 in l allele homozygotes (43.13 ± 11.49%; p = 0.029). However, 5-HTTLPR genotypes were not significantly associated with remission (p > 0.05). CONCLUSIONS Our results show that treatment response to escitalopram at 8 weeks was moderated by 5-HTTLPR, with better response rates for s allele carriers than for l allele homozygotes. Although the role of 5-HTTLPR as a definite predictor of selective serotonin reuptake inhibitor treatment response cannot be confirmed from current results, they do suggest a trend for better response in s allele carriers.

Abstract
BACKGROUND Alopecia areata (AA) is characterized by rapid and complete hair loss in one or multiple areas of the scalp. Stress is an important triggering factor in AA. AIM To identify the inhibitory effect of tianeptine on catagen induction in C57BL/6 mice with AA-like lesions induced by ultrasonic wave stress (UWS). METHODS The mice were divided into four groups. Group 1 received oral tianeptine before and after UWS; group 2 received oral tianeptine only after UWS; group 3 was given UWS treatment only; and group 4 (negative control group) was not given any treatment. Phototrichigraphy and dermatoscopy were used for assessment. Histological analysis was performed using haematoxylin and eosin, toluidine blue, Masson trichrome and Verhoeff-van Gieson stains. Immunohistochemical analysis was also performed. The level of apoptosis and expression of neuropeptides in the skin were assessed by terminal deoxynucleotidyl transferase dUTP nick end labelling and immunofluorescence assays. RESULTS Mice in group 1 had an increased rate of hair growth and greater hair-shaft thickness compared with mice in groups 2 and 3. In addition, mice in group 1 had a higher number of anagen hair follicles, increased synthesis of collagen and elastic fibres, decreased mast-cell degranulation, reduction in cell apoptosis in hair follicles, and recovery of vitamin D receptor expression. Expression of neuropeptides (substance P, calcitonin gene-related peptide) was not altered. CONCLUSIONS Tianeptine might play a role in suppressing catagen induction in a stress-induced AA mouse model.

Abstract
Dietary lysine restriction may differentially affect body growth and lipid and nitrogen metabolism, depending on the degree of lysine restriction. This study was conducted to examine the effect of dietary lysine restriction on growth and lipid and nitrogen metabolism with two different degree of lysine restriction. Isocaloric amino acid-defined diets containing 1.4% lysine (adequate), 0.70% lysine (50% moderate lysine restriction) and 0.35% lysine (75% severe lysine restriction) were fed from the age of 52 to 77 days for 25 days in male Sprague-Dawley rats. The 75% severe lysine restriction increased (p < 0.05) food intake, but retarded (p < 0.05) growth, increased (p < 0.05) liver and muscle lipid contents and abdominal fat accumulation, increased (p < 0.05) blood urea nitrogen levels and mRNA levels of the serine-synthesizing 3-phosphoglycerate dehydrogenase gene, but decreased (p < 0.05) urea cycle arginase gene mRNA levels. In contrast, the 50% lysine restriction did not significantly (p > 0.05) affect body growth and lipid and nitrogen metabolism. Our results demonstrate that severe 75% lysine restriction has detrimental effects on body growth and deregulate lipid and nitrogen metabolism.
