Sanaa E Tork, Magda M Aly, Omar Elsemin
In the current study, the purified l-glutaminase from Streptomyces pratensis NRC10 (GenBank number KC857622) was characterized. Its molecular weight was estimated to be 46 kDa and isoelectric point 7.4. Its Vmax was calculated to be 2.19 U/mg/min, while Km was 0.175 mM. The optimum pH and temperature were 9 and 45 °C, respectively. It was thermostable at 45 °C but thermally inactivated at 60 °C after 50 min. Moreover, its enzymatic activity was enhanced by K+ ions and inhibited by Mg2+ , Cu2+ , Ag+ , Hg2+ , Ni2+ , Fe2+ , Cr2 , Na+ , Ca2+ , and EDTA...

Transplantation is currently the therapy of choice for endstage organ failure even though it requires long-term immunossuppresive therapy, with its numerous side effects, for acceptance of the transplanted organ. In rare cases however, patients develop operational tolerance, that is, graft survival without immunosuppression. Studies conducted on these patients reveal genetic, phenotypic, and functional signatures. They provide a better understanding of the immunological mechanisms involved in operational tolerance and define biomarkers that could be used to adapt immunosuppressive treatment to the individual, safely reduce immunosuppression doses, and ideally and safely guide immunosuppression withdrawal...

BACKGROUND AND PURPOSE: Functional selectivity describes the ability of ligands to differentially regulate multiple signalling pathways when coupled to a single receptor and the operational model is commonly used to analyse these data. Here, we assess the mathematical properties of the operational model and evaluate the impact of fixing parameters on model performance. EXPERIMENTAL APPROACH: The operational model was evaluated using both a mathematical identifiability analysis and simulation...

Adenoviruses are double-stranded DNA viruses that typically cause mild self-limiting respiratory, ocular, and gastrointestinal infections. In immunocompromised patients, especially transplant recipients, the infection can be severe, with dissemination and multiorgan failure. In intestinal transplant recipients, the incidence is as high as 57%. To our knowledge, no standardized guidelines or United States Food and Drug Administration-approved medications exist for the treatment of adenovirus disease. We describe two isolated intestinal transplant recipients who developed adenovirus disease (viremia with viral enteritis) that was managed with a new experimental drug, brincidofovir (an oral lipid conjugate prodrug of cidofovir), as salvage therapy...

Endoplasmic reticulum (ER) stress is activated in non-alcoholic fatty liver disease (NAFLD), raising the possibility that ER stress-dependent metabolic dysfunction, inflammation and cell death underlie the transition from steatosis to steatohepatitis (NASH). Bax inhibitor-1 (BI-1), a negative regulator of the ER stress sensor IRE1α, has yet to be explored in NAFLD as a hepatoprotective agent. We hypothesized that the genetic ablation of BI-1 would render the liver vulnerable to NASH due to unrestrained IRE1α signaling...

A copper-catalyzed activation of C(sp3 )-H bonds of DMF at room temperature was developed, which results in methyl transfer to aromatic amines for efficient synthesis of exceedingly valuable α-amino nitriles. This process features excellent functional group tolerance, a broad substrate scope, and high activity under ambient conditions.

Two-dimensional graphene-like materials, namely MXenes, have been proposed as potential materials for various applications. In this work, the reactivity and selectivity of four MXenes (i.e. M2 C (M = Ti, V, Nb, Mo)) and their oxygen-functionalized forms (i.e. O-MXenes or M2 CO2 ) toward gas molecules were investigated by using the plane wave-based Density Functional Theory (DFT) calculations. Small gas molecules, which are commonly found in flue gas streams, are considered herein. Our results demonstrated that MXenes are very reactive...

Citrulline, the major precursor of ethyl carbamate in soy sauce, is an intermediate catabolite of arginine produced by bacteria present in soy sauce moromi mash. Pediococcus acidilactici is responsible for the formation of citrulline during the lactic acid fermentation process of soy sauce. However, citrulline accumulation during the alcoholic fermentation process and the corresponding bacteria involved have not been identified. Salt-tolerant, arginine-utilizing bacteria were isolated from moromi mash during the alcoholic fermentation process...

The ability to survive conditions of low water activity is critical for the survival of many bacteria in the environment and facilitates disease transmission through food and contaminated surfaces. However, the molecular mechanisms that enable bacteria to withstand this condition remain poorly understood. Here we describe a network of regulators in Escherichia coli that are important for this bacterium to survive dehydration. We found that the transcriptional regulator DksA and the general stress response regulator RpoS play a critical role...

BACKGROUND: Superficial basal cell carcinoma (sBCC) and squamous cell carcinoma in situ (SCCis) are 2 types of nonmelanoma skin cancers (NMSCs) that are amenable to treatment with topical 5-fluorouracil, cryosurgery, or topical imiquimod, among other destructive and surgical modalities. There are few studies examining the effectiveness of combination therapy with 5% 5-fluorouracil and cryosurgery for the treatment of sBCC and SCCis. OBJECTIVES: Our objective was to study the clinical cure rate achieved with the regimen of cryosurgery and a 3-week course of 5% 5-fluorouracil in the treatment of biopsy-proven sBCC and SCCis...

Cutaneous immunity represents a crucial component of the mammalian immune response. The presence of a large array of commensal microorganisms along with a myriad of environmental stresses necessitates constant immuno-surveillance of the tissue. To achieve a perfect balance between immune-tolerance and immune-activation, the skin harbours strategically localised immune cell populations that modulate these responses. To maintain homeostasis, innate and adaptive immune cells assimilate microenvironmental cues and coordinate cellular and molecular functions in a spatiotemporal manner...

Neurosurgical pathologies presenting during pregnancy are uncommon. If present, the situation creates a unique diagnostic, observational, and therapeutic challenge as both lives are placed at potential risk. Surgical procedures during pregnancy are approached carefully as physiological stressors associated with surgery and anesthesia may cause fetal or maternal compromise. We present the only known case of a pseudoaneurysm treated with an awake craniotomy, allowing us to abate the risks associated with general anesthesia in pregnancy...

L-Carnitine (LC) plays an important role in the metabolism of fatty acids, and LC deficiency is associated with a feeling of weakness or general fatigue. Cancer patients receiving chemotherapy often develop LC deficiency, which is considered to be a factor contributing to general fatigue. The aim of the present study was to evaluate the efficacy of LC supplementation as a treatment for general fatigue in cancer patients during chemotherapy. A total of 11 cancer patients who were suffering from general fatigue during chemotherapy in our hospital between September 2014 and December 2015 were examined (6 cases involved adjuvant chemotherapy and 5 cases involved chemotherapy for unresectable or recurrent disease)...

Systemic lupus erythematosus (SLE) is a multi-organ autoimmune disease in which tissue damage is caused by autoantibodies. The induction of specific immune tolerance, including the utilization of immune regulatory cells, may enhance the therapeutic effects of organ transplantation in patients with SLE. Furthermore, inhibiting immune responses has been reported to be an effective treatment for SLE. However, few studies have explored the association between an increased immune tolerance and a decreased immune response in SLE treatment...

European freshwater habitats have experienced a severe loss of plant diversity, regionally and locally, over the last century or more. One important and well-established driver of change is eutrophication, which has increased with rising population density and agricultural intensification. However, reduced disturbance of lake margins may have played an additional key role. The geographical variation in water chemistry, which has set the scene for - and interacted with - anthropogenic impact, is much less well understood...

Under physiological conditions, CD4+ regulatory T (Treg) cells expressing the transcription factor Foxp3 are generated in the thymus [thymus-derived Foxp3+ Treg (tTregs) cells] and extrathymically at peripheral sites [peripherally induced Foxp3+ Treg (pTreg) cell], and both developmental subsets play non-redundant roles in maintaining self-tolerance throughout life. In addition, a variety of experimental in vitro and in vivo modalities can extrathymically elicit a Foxp3+ Treg cell phenotype in peripheral CD4+ Foxp3- T cells, which has attracted much interest as an approach toward cell-based therapy in clinical settings of undesired immune responses...
