We aimed toassess the efficacy of lactulose as prophylaxis against hepatic encephalopathy (HE) in cirrhotic patients with acute upper gastrointestinal bleeding (AUGIB).<br /><br /> We conducted a randomized, double-blinded, placebo-controlled, multicenter study from October 2012 to February 2014. Cirrhotic patients presenting with AUGIB (aged 18-80years, without HE at the time of admission) were enrolled and randomized to receive blinded medications (both physically indistinguishable), labeled "Lactulose A" and "Lactulose B" for 5days along with standard treatment depending on the type of bleeding (variceal and nonvariceal). The primary endpoint was the development of overt HE according to the West-Haven criteria. Modified intention-to-treat analysis was performed.<br /><br /> Forty-six patients completed the protocol Lactulose A (placebo, n= 22) and Lactulose B (lactulose, n= 24). There was no significant difference in baseline characteristics and clinical outcomes between the two groups. Nine (19.6%) patients developed HE five (22.7%) in the placebo group and four (16.7%) in the lactulose group (p= 0.718). One patient (2.2%) died inlactulose group. All patients tolerated the medication and no significant difference in adverse effects was detected (59.1% inplacebo vs. 50.0% inlactulosegroup, p= 0.536). On multivariate analysis, increased baselineChild-Turcotte-Pugh (CTP) score (odds ratio [OR] 2.176; 95% confidence interval [CI] 1.012-4.681, p= 0.047) and presence of diarrhea (OR 16.261; 95% CI 1.395-189.608, p= 0.026) were independent risk factors for the development of HE.<br /><br /> Five-day lactulose is ineffective as prophylaxis against HE in cirrhotic patients with AUGIB. Unnecessarytreatment with laxatives should be avoided in these patients.<br /><br /> Clinical trial registry number TCTR20200526003 (retrospectively registered).<br /><br />Clinical trial registry number TCTR20200526003 (retrospectively registered).<br /><br /> Sexual functional deficiency occurs at some point in life and becomes a problematic issue in middle-aged adulthood. Regenerative medicine, especially mesenchymal stem cell (MSC) transplantation, has developed extensively, with preclinical and clinical trials emphasizing the benefits of stem cell therapy for restoration of sexual deficiency. This study was designed to develop a new therapeutic stem cell treatment for people with sexual functional deficiency.<br /><br /> Thirty-one patients, including 15 males and 16 females with a medical history of reduced sexual activity, met the inclusion criteria and were enrolled in the study, phase I/IIa clinical trial with a 12-month follow-up. Adipose tissue-derived mesenchymal stem/stromal cells (ADSC) were isolated by type I collagenase digestion and cultured at the Stem Cell Core Facility under ISO 14644-1. Each participant received 1 million cells/kg of body weight via the intravenous route. Safety was evaluated by assessing the occurrence of adverse events or severe adveristered November 20, 2017.<br /><br />ClinicalTrials.gov. NCT03346967, Registered November 20, 2017.<br /><br /> Aberrant T cell antigen expression has been well documented in diffuse large B cell lymphomas. However, co-expression of multiple T cell antigens including CD3, which has been considered a specific marker for T cells is extremely rare. Awareness about such aberrant expression is important so as not to misdiagnose or wrongly classify a lymphoma. The aim of this article is to report such a case.<br /><br /> A 68-year-old postmenopausal lady, diabetic and hypertensive, presented with an axillary lump of one week's duration. There was no other relevant medical history. Ultrasonography revealed multiple hypoechoic cystic lesions varying in size from 3.9 to 4.2 cm<br /><br /> . Aspiration was suggestive of an infective pathology. Excision biopsy of the mass was diagnosed as diffuse large B cell lymphoma with aberrant T cell antigen expression.

The predicament lies in classifying it as a B cell lymphoma with an aberrant expression of T cell markers versus a T cell lymphoma with an aberrant B cell marker expression which has a significant implication on the treatment offered. This can be solved by looking at the expression of the B cell specific transcription factors. The key to diagnosis lies in the knowledge of their existence and the application of a panel of markers.<br /><br />The case presented as a diagnostic dilemma for the pathologist.

Pancreatic β cells which synthesize and secrete insulin are prone to oxidative stress induced damage because of low cellular antioxidant enzymes. To delineate the effects of quercetin on pancreatic β cells we evaluated the protective effect of quercetin on TC6 insulinoma cells subjected to oxidative stress induced by tert-butyl-hydrogen-peroxide (TBHP). Quercetin was found to reduce TBHP induced apoptosis and trigger insulin secretion in response to glucose, in a dose-dependent manner. Quercetin treatment increased mitochondrial biogenesis, caused hypertrophy in pancreatic β cells and activated mTOR signaling with a transient change in mitochondrial membrane potential and AMP/ATP. Activation of mTOR signaling resulted in enhanced insulin secretion in TC6 cells.Brefeldin A (BFA) disrupts the structure of the Golgi apparatus to trigger ER stress signaling pathways. On the other hand, treatment with BFA induces the activation of CREB3, the protein structure of which is similar to that of ATF6. In this study, we established Neuro2a cells in which three different transcription factors, namely, ATF4, ATF3 and CREB3, were deficient using the CRISPR/Cas9 approach, and we investigated the BFA-induced ER and Golgi stress response in these cells. BFA treatment rapidly induced ATF4, ATF3, Herp and GADD153 protein expression in Neuro2a cells. ATF4-deficient Neuro2a cells exhibited significantly decreased mRNA and protein expression of ATF3 and Herp but not GADD153; however, cells deficient in ATF3 exhibited minimal effects on GADD34, GADD153 and Herp expression. The cleavage of CREB3 in Neuro2a cells was triggered by BFA; however, the expression of several ER and Golgi stress-related factors was hardly influenced by the CREB3 deficiency in these Neuro2a cells. This study shows that CREB3 minimally associates with typical ER stress-inducible responses in Neuro2a cells.
