Inhibition of iNOS induction and nf-κΒ activation by taste compounds from the edible mushroom tricholoma caligatum (Viv.) ricken

© 2019 ACG Publications. All rights reserved. Tricholoma caligatum (Viv.) Ricken is an edible mushroom that belongs to matsutake group. The first chemical investigation of the three different extracts of Tricholoma caligatum resulted in two new compounds, 8-demethoxylascivol (1) and 8-epi-lascivol (2) and six known compounds, lascivol (3), trametenolic acid (4), ergosterol (5), ergosterol peroxide (6), 5α, 6α-epoxyergosterol (7), and cerebroside B (8). Their structures were elucidated by spectroscopic analyses including 1D and 2D NMR data. The biological activities of all the compounds were evaluated toward multiple targets related to inflammation and metabolic disorder such as NF-κΒ, iNOS and ROS. The findings of this study reveal that the edible mushroom Tricholoma caligatum could be a potential source for anti-inflammatory bioactive metabolites

2-Anilino-3-(2-hy­droxy­prop­yl)-4-methyl-1,3-thia­zol-3-ium chloride

In the title compound, C13H17N2OS+·Cl−, the thia­zolium ring mean plane makes a dihedral angle of 55.46 (9)° with the benzene ring. In the propanol group, the N—C—C—C and N—C—C—O torsion angles are 172.58 (15) and 52.9 (2)°, respectively, and the S—C—C—C torsion angle is 178.99 (18)°. In the crystal, mol­ecules are linked by O—H⋯Cl and N—H⋯Cl hydrogen bonds, forming zigzag chains along [001]. There is also a C—H⋯Cl inter­action present

The Effects of Age at Circumcision on Premature Ejaculation 2

SUMMARY Objective: The objective of this study was to analyze the effect of age at circumcision on premature ejaculation (PE). Materials and Methods: The study included 40 healthy male controls and 40 male patients diagnosed as PE according to American Psychiatric Association criteria and the Golombok-Rust Inventory of Sexual Satisfaction (GRISS) premature ejaculation subscale. The 2 groups were compared according to age at circumcision and GRISS score. Results: The PE group and control group were sociodemographically similar, but differed in marital status. The groups differed in GRISS communication, degree of satisfaction, avoidance, sensuality, erectile dysfunction, and PE subscale scores. These differences only displayed a dysfunction in the degree of satisfaction and premature ejaculation subscales. The groups also differed in age at circumcision; accordingly, those that were circumcised at ≥7 years of age had higher GRISS scores and a higher risk of having PE than those that were circumcised at >7 years of age. Conclusion: Age at circumcision had an effect on PE; circumcision at ≥7 years of age was associated with an increase in the risk of PE, as compared to circumcision at >7 years of age. We think that families should have their boys circumcised before the age of 7 years and highly recommend that the procedure be performed within in the first 3 years of life

Identification of heavy metal ions from aqueous environment through gold, Silver and Copper Nanoparticles: An excellent colorimetric approach

Heavy metal pollution has become a severe threat to human health and the environment for many years. Their extensive release can severely damage the environment and promote the generation of many harmful diseases of public health concerns. These toxic heavy metals can cause many health problems such as brain damage, kidney failure, immune system disorder, muscle weakness, paralysis of the limbs, cardio complaint, nervous system. For many years, researchers focus on developing specific reliable analytical methods for the determination of heavy metal ions and preventing their acute toxicity to a significant extent. The modern researchers intended to utilize efficient and discerning materials, e.g. nanomaterials, especially the metal nanoparticles to detect heavy metal ions from different real sources rapidly. The metal nanoparticles have been broadly utilized as a sensing material for the colorimetric detection of toxic metal ions. The metal nanoparticles such as Gold (Au), Silver (Ag), and Copper (Cu) exhibited localized plasmon surface resonance (LPSR) properties which adds an outstanding contribution to the colorimetric sensing field. Though, the stability of metal nanoparticles was major issue to be exploited colorimetric sensing of heavy emtal ions, but from last decade different capping and stabilizing agents such as amino acids, vitmains, acids and ploymers were used to functionalize the metal surface of metal nanoparticles. These capping agents prevent the agglomeration of nanoparticles and make them more active for prolong period of time. This review covers a comprehensive work carried out for colorimetric detection of heavy metals based on metal nanoparticles from the year 2014 to onwards. © 202

Apoptosis, mastocytosis, and diminished adipocytokine gene expression accompany reduced epididymal fat mass in long-standing diet-induced obese mice

<p>Abstract</p> <p>Background</p> <p>Obesity is characterized by increased cell death and inflammatory reactions in the adipose tissue. Here, we explored pathophysiological alterations taking place in the adipose tissue in long-standing obesity. In the epididymal fat of C57BL/6 mice fed a high-fat diet for 20 weeks, the prevalence and distribution of dead adipocytes (crown-like structures), mast cells (toluidine blue, mMCP6), macrophages (F4/80), and apoptotic cells (cleaved caspase-3) were measured. Moreover, gene and/or protein expression of several adipocytokines (leptin, adiponectin, TNF-α, IL-10, IL-6, MCP-1), F4/80, mMCP6, cleaved caspase-3 were determined.</p> <p>Results</p> <p>We observed that the epididymal fat mass was lower in obese than in lean mice. In obese mice, the epididymal fat mass correlated inversely with body weight and liver mass. Dead adipocytes, mast cells, macrophages, and apoptotic cells were abundant in the epididymal fat of obese mice, especially in the rostral vs. caudal zone. Accordingly, mMCP6, F4/80, and cleaved caspase-3 gene and/or protein expression was increased. Conversely, adiponectin, leptin, IL-6, and MCP-1 gene expression levels were lower in the epididymal fat of obese than lean mice. Although TNF-α and IL-10 gene expression was higher in the epididymal fat of obese mice, their expression relative to F4/80 and mMCP6 expression were lower in the heavily infiltrated rostral than caudal zone.</p> <p>Conclusions</p> <p>This study demonstrates that in mice with long-standing obesity diminished gene expression of several adipocytokines accompany apoptosis and reduced mass of the epididymal fat. Our findings suggest that this is due to both increased prevalence of dead adipocytes and altered immune cell activity. Differential distribution of metabolically challenged adipocytes is indicative of the presence of biologically diverse zones within the epididymal fat.</p

Nodular melanoma presenting with rapid progression and widespread metastases: a case report

<p>Abstract</p> <p>Introduction</p> <p>Melanoma is responsible for 1% to 2% of all cancer deaths around the world. Nodular melanoma often carries a poor prognosis because of no prodromal radial growth phase, early distant metastasis and significant tumor volume.</p> <p>Case presentation</p> <p>We present a case of progressive melanoma. A 51-year-old man was admitted to our hospital with dyspnea and skin lesions. These were multiple, dark colored, firm, and nodular and varied in size. He was diagnosed with melanoma. Temozolomide was administered, but he died of respiratory failure within a week after diagnosis.</p> <p>Conclusion</p> <p>Nodular melanoma tends to spread rapidly and eventually metastasize to vital organs. It may be fatal within months of recognition.</p

Management of Patients with Refractory Cardiogenic Shock and Cardiointestinal Syndrome with Impella 5.5 as Bridge to Decision: Case Series

Patients with advanced heart failure require multi-system management as a majority succumb to end-organ dysfunction, including gastrointestinal sequelae. Temporizing measures, such as early mechanical circulatory support, can assist in the recovery of patients with acute cardiogenic shock. The temporary support can improve patient characteristics to enable future definitive heart failure therapies such as durable left ventricular assist devices and orthotopic heart transplantation. We present two cases of cardiogenic shock that were successfully bridged with an Impella 5.5 (Abiomed). The management enabled the patients to recover from reversible cardiointestinal syndrome and undergo successful definitive therapies
