Salinity Stress in Legume Crops: A Comprehensive Review of Effects, Mechanisms, and Mitigation Strategies
Authors: Chaudhary Sahil B , Gujjar Deshraj , Kumar Bijendra , Patel Smit , Simran  
Published: July 2024

Salinity stress poses a significant challenge to global crop production, particularly in regions relying heavily on irrigation. This review explores the detrimental impacts of salt stress on grain legumes, crucial plants renowned for their high protein content and nitrogen-fixing ability. The increasing use of saline groundwater and the accumulation of soil salts threaten the sustainability of legume cultivation worldwide. Salt stress disrupts fundamental physiological processes in legumes, including photosynthesis, hormone regulation, and nutrient uptake, resulting in substantial reductions in yield and quality. It exacerbates osmotic stress and ion toxicity, severely compromising plant health and productivity. Understanding the intricate mechanisms underlying salt tolerance in grain legumes is pivotal for developing effective mitigation strategies. This review synthesizes current knowledge on the tolerance mechanisms employed by legumes to cope with salt stress. It examines various management approaches aimed at enhancing their resilience under saline conditions. Key findings highlight that salt stress can lead to over 70% reductions in growth and variable decreases in yield and mineral absorption rates. Innovative strategies such as genetic engineering of transgenic varieties and advanced crop management practices offer promising avenues to enhance salt tolerance and boost legume productivity on salinity-affected soils. Furthermore, insights into mechanisms such as ion compartmentalization and ion excretion provide critical pathways for developing salt-resistant legume cultivars. Apoplastic acidification emerges as a reliable indicator of salt stress resistance in these plants. By elucidating these mechanisms and strategies, this review contributes to the ongoing efforts aimed at safeguarding legume production and global food security in the face of escalating salinity stress.
Nanocontainer‐Based Anticorrosive Coatings: Effect of the Container Size on the Self‐Healing Performance
Authors: Borisova Dimitriya , Akçakayıran Dilek , Schenderlein Matthias , Möhwald Helmuth , Shchukin Dmitry G. 
Published: March 2013

AbstractOrganic coatings based on inhibitor loaded inorganic containers for smart corrosion inhibition are presented. The overall coating performance is strongly influenced by the containers as well as their inhibitor capacity, compatibility with the coating matrix, and size. The important effect of container size is described for the first time in this work by investigating two types of mesoporous silica containers of different diameters: 80 and 700 nm. The coating physical properties (thickness and adhesion) are comparable for both container types. In contrast, the coating barrier properties are strongly influenced by the container size as assessed with electrochemical impedance spectroscopy (EIS). The incorporation of bigger containers reduces the coating resistance by a factor of two. Surprisingly, despite the similar amounts (20 wt%) of loaded inhibitor (2‐mercaptobenzothiazole), different active inhibition ability is detected with the scanning vibrating electrode technique (SVET). Therefore, it is found that coatings with smaller containers exhibit better self‐healing performance.

Bioindicator role of aquatic Ranunculus in Mediterranean freshwater habitats
Authors: Lumbreras Ana , Pardo Cristina , Molina José Antonio 
Published: March 2013

ABSTRACTMediterranean freshwater ecosystems are among the most endangered by global change. In order to design appropriate conservation policies it is essential to ascertain which are the most vulnerable freshwater habitats.Aquatic Ranunculus communities are used as target habitats to answer the following questions: (a) Does regional climate influence the distribution of aquatic plant communities? (b) Do nutrient enriched and base‐rich waters act as a filter for aquatic habitats, reducing the number of plant communities? and (c) Is the European Habitats Directive classification for freshwater habitats that support Ranunculus species fit for purpose?The floristic consistency of nine Ranunculus communities and their affinity with freshwater ecosystem types was analysed. A study was made of the relationships between environmental factors, including climate and aquatic physico‐chemical parameters, and the composition of Ranunculus communities. Significant environmental parameters were analysed separately to define the ecological niche occupied by Ranunculus species.At a regional scale, climatic variables best explain the distribution patterns of the Ranunculus communities, and separate Atlantic communities (Ranunculus tripartitus, R. omiophyllus, R. ololeucos and R. fluitans communities) at localities with a higher rainfall/temperature ratio from the rest. At a local scale, a strong relationship was found between the distribution of Ranunculus communities and physico‐chemical properties, in the following order of importance: alkalinity, flow, and nutrient status. Hard waters reduce Ranunculus community richness to a R. trichophyllus community, and waters enriched by phosphates to a R. penicillatus community.The rainfall/temperature ratio, alkalinity, and eutrophication shape the vegetation composition in Mediterranean freshwater habitats. In view of this, some gaps were identified in the European Habitats Directive with regard to Atlantic and oligotrophic base‐poor freshwater habitats. Copyright © 2013 John Wiley & Sons, Ltd.
Carbimazole embryopathy in a Chinese population: Case series and literature review
Authors: Ting Yuen Ha , Zhou Yan , Lao Terence T. 
Published: March 2013

BACKGROUNDThe data in the literature suggests that Methimazole (MMI)/Carbimazole (CMZ) embryopathy is rare. This study examined the incidence of CMZ embryopathy in the Hong Kong Chinese population and the factors associated with its development.METHODSOf the 145 pregnant women with hyperthyroidism managed from 2008 to 2010, 29 (20%) had taken CMZ during pregnancy. The presence and details of birth defects, the dosage of CMZ, and the period of exposure during pregnancy were examined in these 29 pregnancies. All cases of CMZ embryopathy in the English literature were reviewed in the same way.RESULTSOf the 27 babies (93.1%) with known outcome, 3 had aplasia cutis and 1 had an omphalocele in addition, and 1 affected baby had a sibling with aplasia cutis and patent vitellointestinal duct. The incidence of CMZ embryopathy in our study group is 11.1%. Amongst the 21 cases of CMZ embryopathy in the literature, 85% were exposed to a CMZ dosage of ≥20 mg/day, and the minimum duration of exposure being 7 weeks from last menstrual period. The most common abnormality is ectodermal anomaly (62%), followed by oro‐nasal anomaly (48%), facial dysmorphism (38%), gastrointestinal anomaly (33%) and abdominal wall defect (19%). There was no relationship between the type of abnormality and the dosage or duration of exposure to CMZ.CONCLUSIONSThe incidence of CMZ embryopathy in our study group is 11.1%. Critical factors for its development are exposure to a CMZ dosage of ≥20 mg/day before 7 weeks of gestation. Genetic susceptibility may also play a role.

Vom Nutzen der Historie für die Wissenschaftsphilosophie
Authors: Schickore Jutta 
Published: March 2013

AbstractOf the Merits of History for Philosophy of Science. This essay is inspired by some of the contributions to the two special issues “History of Science and Philosophy of Science” of the journal Berichte zur Wissenschaftsgeschichte. I consider possible roles of historical study for philosophy of science. The first part of the essay discusses contributions to the Anglo‐American debate about history and philosophy of science in the 1960s and 1970s. I present two approaches. According to Larry Laudan and others, philosophy of science should be regarded as an empirical theory of science, which has to be tested against historical episodes. I show why this conception of philosophy of science is problematic. According to Dudley Shapere and others, by contrast, philosophical analysis of science requires hermeneutic understanding and should include the study of the development of scientific knowledge. I agree that the method of philosophy of science is best described as hermeneutic. To defend a genuine historical‐hermeneutic philosophy of science, however, one would have to demonstrate the privilege of historical analysis over other forms of science studies, such as sociology of science or studies of science communication. I do not think that such a demonstration can be made.

Abstract

Background
Data on outcomes of left hepatic trisectionectomy (LT) for perihilar cholangiocarcinoma are limited. The aim of this study was to clarify short- and long-term outcomes of LT for perihilar cholangiocarcinoma.

Methods
Patients with perihilar cholangiocarcinoma who underwent LT between January 2000 and October 2011 were analysed. Surgical variables, mortality, morbidity (Clavien grade I–V), recurrence sites and survival were compared between subjects who underwent LT, right hemihepatectomy or left hemihepatectomy.

Results
A total 214 patients underwent resection for perihilar cholangiocarcinoma, 25 (11·7 per cent) of whom underwent LT, 88 (41·1 per cent) right hemihepatectomy and 94 (43·9 per cent) left hepatectomy. There were no deaths among those who had LT, but 20 patients developed complications. The incidence of grade IIIa complications was significantly higher among patients who underwent LT than in patients who had right or left hemihepatectomy (P = 0·001 and P &lt; 0·001 respectively). Only one patient developed a grade IIIb or IV complication (liver failure) after LT. The overall 5-year survival rate after LT was 39 per cent and median survival was 45 months. There were no significant differences in survival between patients who underwent LT and those who had a right or left hemihepatectomy.

Conclusion
LT may provide a good outcome for advanced perihilar cholangiocarcinoma.

ABSTRACTA rapid, simple, sensitive and selective ultraperformance liquid chromatography–tandem spectrometry (UPLC‐MS/MS) method for the determination of nalbuphine and its prodrug sebacoly dinalbuphine ester (SDE) was developed and validated in human plasma. The sample pretreatment involves basification and iterative liquid–liquid extraction with ethyl‐ether–dichloromethane (7:3, v/v) solution, followed by LC separation and positive electrospray ionization (ESI) API‐3000 mass spectrometry detection. The chromatography was on a Waters Acquity UPLC BEH HILIC column (2.1 × 100 mm, 1.7 µm). The mobile phase was composed of acetonitrile and water (83:17, v/v) that contained 0.2% formic acid and 4 mm ammonium formate at a flow rate of 0.25 mL/min. Ethylmorphine and naloxine were selected as the SDE and nalbuphine internal standard (IS), respectively. The calibration curve for both was linear over the range from 0.05 to 20 ng/mL, with correlation coefficients ≥0.995. The lower limit of quantification was set at 0.05 ng/mL. The intra‐ and inter‐day precision values for nalbuphine and SDE were acceptable as per FDA guidelines. The method was applied successfully to determine nalbuphine concentration in human plasma samples obtained from four Taiwanese volunteers receiving intramuscularly administration of sebacoyl dinalbuphine ester. The method is sensitive, selective and directly applicable to human pharmacokinetic studies involving nalbuphine. Copyright © 2013 John Wiley & Sons, Ltd.
Preparation of Gradient Surfaces by Using a Simple Chemical Reaction and Investigation of Cell Adhesion on a Two‐Component Gradient
Authors: Lee Jeongwook , Choi Inseong , Yeo Woon‐Seok 
Published: March 2013

AbstractThis article describes a simple method for the generation of multicomponent gradient surfaces on self‐assembled monolayers (SAMs) on gold in a precise and predictable manner, by harnessing a chemical reaction on the monolayer, and their applications. A quinone derivative on a monolayer was converted to an amine through spontaneous intramolecular cyclization following first‐order reaction kinetics. An amine gradient on the surface on a scale of centimeters was realized by modulating the exposure time of the quinone‐presenting monolayer to the chemical reagent. The resulting amine was used as a chemical handle to attach various molecules to the monolayer with formation of multicomponent gradient surfaces. The effectiveness of this strategy was verified by cyclic voltammetry (CV), matrix assisted laser desorption/ionization time‐of‐flight (MALDI‐TOF) mass spectrometry (MS), MS imaging, and contact‐angle measurements. As a practical application, cell adhesion was investigated on RGD/PHSRN peptide/peptide gradient surfaces. Peptide PHSRN was found to synergistically enhance cell adhesion at the position where these two ligands are presented in equal amounts, while these peptide ligands were competitively involved in cell adhesion at other positions. This strategy of generating a gradient may be further expandable to the development of functional gradient surfaces of various molecules and materials, such as DNA, proteins, growth factors, and nanoparticles, and could therefore be useful in many fields of research and practical applications.
Artificial Allosteric Receptors
Authors: Kremer Christopher , Lützen Arne 
Published: March 2013

AbstractCooperative effects in the binding of two or more substrates to different binding sites of a receptor that are a result of a conformational change caused by the binding of the first substrate—also referred to as the effector—are called allosteric effects. In biological systems, allosteric regulation is a widely used mechanism to control the function of proteins and enzymes in cellular metabolism. Inspired by this a lot of efforts have been made in supramolecular chemistry to implement this concept into artificial systems to control functions as molecular recognition, signal amplification, or even reactivity and catalysis. This review gives an up‐to‐date overview over the different approaches that have been reported ever since the first examples from the late 1970s/early 1980s. It covers both homo‐ and heterotropic examples and is divided according to the nature of the effector—cationic, anionic, or neutral—effectors and systems that use combinations of those.
