#1
Firozeh Saberzadeh Sarvestani, Hossein Esmaeili, Bahman Ramavandi
In this paper, a new and facile approach for molybdate loading in the brown algae of Sargassum angustifolium is introduced. The molybdate ions were entered into the algae body during a short cultivation to produce algae-Mo as a novel adsorbent for eliminating phosphate ions from synthetic and real wastewaters. Results of the surface analysis showed that molybdate loading onto the algae was successfully performed. Herein, basic variables, such as initial solution pH, adsorbent dosage, contact time, phosphate concentration, and temperature, were investigated in detail to assess the phosphate adsorption performance of algae-Mo...

Neha Kapoor, Sanjai Saxena
Xanthine oxidase is a key enzyme responsible for hyperuricemia, a pre-disposing factor for Gout and oxidative stress-related diseases. Only two clinically approved xanthine oxidase inhibitors Allopurinol and Febuxostat are currently used for treatment of hyperuricemia. However, owing to their side effects there is a need for new non-purine-based selective inhibitors of xanthine oxidase. In the process of exploring novel xanthine oxidase inhibitors and anti-oxidants, we screened the culture filtrate of 07 novel species of Muscodor, a sterile endophytic fungi isolated from Cinnamomum and Aegle marmelos...

Wood industries and agricultural crops generate an inexhaustible supply of by-products like lignin, which constitutes an environmental problem. Increasing efforts have been done to find new applications for lignin. One of them is as a food additive, but its chemical nature makes it sensitive to browning which constitutes a major drawback for this type of lignin application. In the present study we are documenting how color stabilization of a commercial kraft lignin was achieved after the treatment with Penicillium chrysogenum var...

RATIONALE: Mechanical thrombectomy (MT) with a stent retriever (SR), in association with intravenous (IV) rtPA, is now the standard of care in anterior circulation ischemic stroke caused by large vessel occlusion (LVO). Favorable outcome is strongly associated with the successful reperfusion status. New techniques for MT such as contact aspiration (CA) seem promising to increase reperfusion status and clinical outcome in retrospective studies. We aim at ascertaining whether CA is more efficient than stent retriever as a front-line endovascular procedure...

Sang Myung Woo
The term of biliary tract cancer (BTC) refers to all tumors that arise from the biliary tract or the biliary drainage system, including the intra- and extra-hepatic bile ducts as well as the gallbladder. BTCs are aggressive tumors with limited treatment options and poor overall survival. Currently, surgery remains to be the only potentially curative treatment, and most patients develop recurrence. For advanced tumors, only limited effective treatment modalities exist today. Gemcitabine plus cisplatin is considered as a standard option for advanced biliary cancer...

Sara Scheveneels, Yannick Boddez, Marc Patrick Bennett, Dirk Hermans
BACKGROUND AND OBJECTIVES: During exposure therapy, patients are encouraged to approach the feared stimulus, so they can experience that this stimulus is not followed by the anticipated aversive outcome. However, patients might treat the absence of the aversive outcome as an 'exception to the rule'. This could hamper the generalization of fear reduction when the patient is confronted with similar stimuli not used in therapy. We examined the effect of providing information about the typicality of the extinction stimulus on the generalization of extinction to a new but similar stimulus...

Systemic lupus erythematous is a multi-organ autoimmune disease in which the patient has "lost" self- tolerance and developed immune-complexes containing self-antigen that cause disease through tissue inflammation and multi-organ damage. Patients often have unpredictable flares in symptoms with poorly identified triggers. However, it has been suggested in other literature that exogenous exposures, including ingested beef, cigarette smoke, UV radiation, metal-complexing agents, and infections can contribute to exacerbations and improvements in SLE symptoms...

Oral ponesimod is a new therapy for the treatment of moderate-to-severe plaque psoriasis. Vaclavkova et al conducted a phase 2 trial that demonstrated moderate efficacy of ponesimod in the treatment of psoriasis. Here we discuss various biologic agents with alternative mechanisms of action, that have demonstrated superior efficacy in psoriasis, and call into question the risks versus benefits of ponesimod therapy.

During the last few decades, management of psoriasis has changed worldwide, owing to a better understanding of its pathophysiology and the introduction of new treatments. As experts in the field of dermatology, specialists from Latin America collaborated to develop this review and further provide an update on the current state of psoriasis management in Latin America. With the goal of summarizing the latest information on psoriasis in most countries in Latin America, we conducted a literature search to obtain relevant articles published in the medical/scientific literature in Latin American countries over the last 10 years; in addition, we completed a questionnaire comprised of 20 questions on important issues related to psoriasis...

Hyperhidrosis, or abnormally increased sweating, is a condition that may have a primary or secondary cause. Usually medication- induced secondary hyperhidrosis manifests with generalized, rather than focal sweating. We report a 32-year-old woman with a history of palmoplantar hyperhidrosis for 15 years who presented for treatment and was prescribed oral glycopyrrolate. One month later, the palmoplantar hyperhidrosis had resolved, but she developed new persistent craniofacial sweating. After an unsuccessful trial of clonidine, oxybutynin resolved the craniofacial hyperhidrosis...

Melanoma occurrence during treatment with anti-tumor necrosis factor is considered an incidental event, although very recent studies suggest a risk. Etanercept is a fusion protein that binds the tumor necrosis factor receptor and is included among TNF inhibitors, approved for the treatment of several autoimmune diseases, such as psoriasis.We described a 79-year-old man with psoriasis, being treated with etanercept, who presented with a new brown to black macule on his right shoulder; this was immediately surgically excised...

A K Gupta, M Cernea, C W Lynde
Tofacitinib is an oral immunosuppressant approved for the treatment of rheumatoid arthritis (RA) and is currently undergoing investigation (Phase III trials) for treating chronic plaque psoriasis. Tofacitinib inhibits Janus kinases (JAKs), which are essential for the signaling of multiple inflammatory pathways and have been implicated in the pathogenesis of RA and psoriasis. The efficacy and safety of tofacitinib in the treatment of RA and psoriasis have been demonstrated in Phase III trials. Across all studies, the efficacy of tofacitinib in alleviating symptoms of RA and psoriasis were superior to placebo...

Background.: Daily trimethoprim-sulfamethoxazole (TMP-SMX) and insecticide treated nets (ITNs) remain the main interventions for prevention of malaria in HIV-infected pregnant women in Africa. However, antifolate and pyrethroid resistance threaten the effectiveness of these intervention and new ones are needed. Methods.: We conducted a double-blind randomized placebo-controlled trial comparing daily TMP-SMX plus monthly dihydroartemisinin-piperaquine (DP) to daily TMP-SMX alone in HIV-infected pregnant women in an area of Uganda where indoor residual spraying of insecticide (IRS) had recently been implemented...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether surgical septal myectomy (SM) is more beneficial than alcohol septal ablation (ASA) in patients with hypertrophic obstructive cardiomyopathy. Altogether 218 articles were found using the reported search, of which 15 studies represented the best evidence to answer the clinical question. There were 14 observational studies and 1 meta-analysis study. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these articles are tabulated...

Background: Cough is the major determinant of tuberculosis transmission. Despite this, there is a paucity of information regarding characteristics of cough frequency throughout the day and in response to tuberculosis therapy. Here we evaluate the circadian cycle of cough; cough frequency risk factors; and the impact of appropriate treatment on cough and bacillary load. Methods: We prospectively evaluated HIV-negative adults (n=64) with a new diagnosis of culture-proven, drug-susceptible pul-monary tuberculosis immediately prior to treatment and repeatedly until treatment day 62...
