#1
Bo-Lin Jian, Chieh-Li Chen, Wen-Lin Chu, Min-Wei Huang
BACKGROUND: Schizophrenia is a neurological disease characterized by alterations to patients' cognitive functions and emotional expressions. Relevant studies often use magnetic resonance imaging (MRI) of the brain to explore structural differences and responsiveness within brain regions. However, as this technique is expensive and commonly induces claustrophobia, it is frequently refused by patients. Thus, this study used non-contact infrared thermal facial images (ITFIs) to analyze facial temperature changes evoked by different emotions in moderately and markedly ill schizophrenia patients...

#3
Lindsey T Davis, Nicole H Weiss, Matthew T Tull, Kim L Gratz
BACKGROUND: Few studies have examined correlates of deliberate self-harm (DSH) among African-Americans. Moreover, most research on the correlates of DSH in general has focused on risk factors rather than protective factors. AIMS: This study examined differences in perceived social support, religiosity (both spirituality and church attendance) and overall life satisfaction between African-Americans with and without a history of DSH, as well as the moderating roles of gender and sexual orientation in these relations...

A significant portion of patients diagnosed with vitelliform macular dystrophy (VMD) do not carry causative mutations in the classic VMD genes BEST1 or PRPH2. We therefore performed a mutational screen in a cohort of 106 BEST1/PRPH2-negative VMD patients in two genes encoding secreted interphotoreceptor matrix proteoglycans-1 and -2 (IMPG1 and IMPG2). We identified two novel mutations in IMPG1 in two simplex VMD cases with disease onset in their early childhood, a heterozygous p.(Leu238Pro) missense mutation and a homozygous c...

INTRODUCTION: Although it is not rare for magnetic resonance imaging findings in Creutzfeldt-Jakob disease to be asymmetric, unilateral clinical syndromes are uncommonly reported and may confound diagnosis. In addition, neurological paraneoplastic syndromes are not common in renal cell carcinoma, though there are cases reported, often without an offending antibody isolated. CASE REPORT: A 66-year-old man was admitted with 1 month of left-sided numbness and "loss of control" of the left arm...

PURPOSE: This is a case presentation of paracentral acute middle maculopathy in a 33-year-old white man with borderline hyperlipidemia. Paracentral acute middle maculopathy was originally thought to be a variant of acute macular neuroretinopathy; however, it is now generally accepted that these two conditions are separate disease entities. The etiology, evolution, and pathophysiology of acute macular neuroretinopathy and paracentral acute middle maculopathy are discussed, as well as current diagnostic techniques...

The exosome complex plays a central and essential role in RNA metabolism. However, current research on functions of exosome subunit in plants is limited. Here, we used an egg cell-specific promoter-controlled CRISPR/Cas9 system to knock out RRP42 which encodes a core subunit of the Arabidopsis exosome and presented evidence that RRP42 is essential for the development of female gametophytes. Next, we designed three different amiRNAs targeting RRP42. The rrp42 knock-down mutants mainly displayed variegated and serrated leaves, especially in cauline leaves...

Maria A Sortino, Salvatore Salomone, Michele O Carruba, Filippo Drago
Polycystic ovary syndrome (PCOS) is characterized by hormonal abnormalities that cause menstrual irregularity and reduce ovulation rate and fertility, associated to insulin resistance. Myo-inositol (cis-1,2,3,5-trans-4,6-cyclohexanehexol, MI) and D-chiro-inositol (cis-1,2,4-trans-3,5,6-cyclohexanehexol, DCI) represent promising treatments for PCOS, having shown some therapeutic benefits without substantial side effects. Because the use of inositols for treating PCOS is widespread, a deep understanding of this treatment option is needed, both in terms of potential mechanisms and efficacy...

Bier spots are asymptomatic white anemic macules with irregular shape located on the upper limbs and less often on the lower limbs and trunkus. They are observed predominantly in youg males and may be idiopathic or associated with other conditions. We report two cases with Bier spots in which videodermatoscopy and nailfold capillaroscopy were performed. Patient 1 was a 34-year-old otherwise healthy male who presented with white spots on his upper limbs for 10 years. Dermoscopy revealed marked narrowing of skin capillaries within the borders of white macules whereas capillaroscopy pattern was normal...

OBJECTIVES: Post-infarction myocardial scar causes adverse left ventricular remodelling and negatively affects the prognosis. We sought to investigate whether scar extent and location obtained by cardiac magnetic resonance may affect the reverse remodelling and survival of heart failure patients undergoing surgical ventricular reconstruction. METHODS: From January 2011 to December 2015, 151 consecutive patients with previous myocardial infarction and left ventricular remodelling underwent surgical ventricular reconstruction at our Institution, of which 88 (58%) patients had a preoperative protocol-standardized late gadolinium enhancement (LGE)-cardiac magnetic resonance examination during the week before surgery...

PHLDA1 (pleckstrin homology-like domain, family A, member 1) is a multifunctional protein that plays distinct roles in several biological processes including cell death and therefore its altered expression has been identified in different types of cancer. Progressively loss of PHLDA1 was found in primary and metastatic melanoma while its overexpression was reported in intestinal and pancreatic tumors. Previous work from our group showed that negative expression of PHLDA1 protein was a strong predictor of poor prognosis for breast cancer disease...

This study aimed to explore the relations between adverse oral outcomes and socioeconomic, demographic, and self-rated oral health variables and to describe their distribution. Principal component analysis was conducted on data from adolescents in the Brazilian National Oral Health Survey (N = 5,445). Higher loadings were found for crowding (0.6), maxillary and mandibular irregularities (0.5), and count of communitary periodontal index (CPI) sextants with bleeding and dental calculus (0.5). The mean rates for periodontal and occlusal disorders were at least two times higher in adolescents from lower income families and those reporting the need for dental prostheses, as well as those dissatisfied with their dental and overall oral health...

RATIONALE: Portal vein thrombosis is a complication after liver transplantation and cavernous transformation of the portal vein (CTPV) is a result of portal vein thrombosis, with symptoms of portal hypertension revealed by an enhanced CT scan. Meso-Rex bypass is an artificial shunt connecting the left portal vein to the superior mesenteric vein and is mainly used for idiopathic cavernomas. This technique is also used for post-transplant portal vein thrombosis in pediatric patients thereby bypassing obstructed sites of the extrahepatic portal vein...
