Bis-(diethyl-dithioxamidate)platinum(ii) is able to transport HCl from the donor aqueous phase to the receiving one over a mean distance of 12 cm in about 3 minutes across an organic membrane in the bulk, without stirring of the organic phase, i.e. at a rate far exceeding the unidirectional macroscopic diffusion coefficient. The way in which this surprising phenomenon can happen is linked to the behaviour of HCl which, because of dynamic interactions with [Pt(HEt2C2N2S2)2] (in which HCl is hosted as a tight ion pair [Pt(H2Et2C2N2S2)2][Cl]2) and chloroform molecules, gives rise to observable nanometric and micrometric domains, more dense than the surrounding bulk, whose formation and disaggregation processes accelerate the unidirectional macroscopic diffusion of HCl. find more Thermodynamic parameters obtained from the study of acid-base behaviour of the system Pt(ii) species/HCl/CHCl3 also agree with the proposed mechanism of HCl transport.Currently, the treatment and care of diabetic wounds, which generally possess the characteristics of a high amputation rate, high recurrence rate and high mortality, has developed into a worldwide challenge. link2 find more Wound dressings have been playing an important role in diabetic wound treatment and continuously innovated to obtain many amazing properties. Among them, hydrogel dressings have become one of the most attractive and promising wound dressings because of their considerable moisture retention, biocompatibility and therapeutic properties. In recent years, with the in depth understanding of the pathogenesis of diabetic wounds, various functionalized hydrogel dressings have been reported and shown encouraging results, which has brought great benefits to the improvement of diabetic wounds. In this work, we will systematically and comprehensively summarize the advances of hydrogel dressings in diabetic wounds, aiming to provide not only theoretical support for hydrogel dressing devising but also inspiration for diabetic wound treatment.We carried out the low-temperature Raman measurement of a sodium pump rhodopsin from Indibacter alkaliphilus (IaNaR) and examined the primary structural change for the light-driven Na+ pump. link2 We observed that photoexcitation of IaNaR produced the distorted 13-cis retinal chromophore in the presence of Na+, while the structural distortion was significantly relaxed in the absence of Na+. This structural difference of the chromophore with/without Na+ was attributed to the Na+ binding to the protein, which alters the active site. find more Using the spectral sensitivity to the ion binding, we found that IaNaR had a second Na+ binding site in addition to the one already specified on the extracellular surface. To date, the Na+ binding has not been considered as a prerequisite for Na+ transport. However, this study provides insight that the protein structural change induced by the ion binding involved the formation of an R108-D250 salt bridge, which has critical importance in the active transport of Na+.Metalloenzymes naturally achieve various reactivities by assembling limited types of cofactors with endogenous amino acid residues. Enzymes containing metal porphyrinoid cofactors such as heme, cobalamin and F430 exert precise control over the reactivities of the cofactors with protein matrices. link3 This perspective article focuses on our recent efforts to assemble metal complexes of non-natural porphyrinoids within the protein matrix of myoglobin, an oxygen storage hemoprotein. Engineered myoglobins with suitable metal complexes as artificial cofactors demonstrate unique reactivities toward C-H bond hydroxylation, olefin cyclopropanation, methyl group transfer and methane generation. In these cases, the protein matrix enhances the catalytic activities of the cofactors and allows us to monitor the active intermediates. The present findings indicate that placing artificial cofactors in protein matrices provides a useful strategy for creating artificial metalloenzymes that catalyse otherwise unfavourable reactions and providing enzyme models for elucidating the complicated reaction mechanisms of natural enzymes.This study analyzed the trend in semen quality of infertile male patients in Wenzhou, China, based on the data obtained from 38 905 patients during 2008-2016 in The First Affiliated Hospital of Wenzhou Medical University (Wenzhou, China). The results showed that only 24.9% of the patients had normal semen quality. link2 For the semen quality of infertile male patients, that of the workers and 40-year-olds was significantly worse than the other occupational and age groups. For all the infertile patients, low semen volume, asthenozoospermia, and teratozoospermia accounted for 8.4%, 50.5%, and 54.1%, respectively. During 2008-2016, the annual mean percentage of fast forward motile spermatozoa, percentage of total forward motile spermatozoa, and percentage of spermatozoa with normal morphology decreased linearly with slopes of -2.11, -2.59, and -0.70, respectively. The proportion of patients with asthenozoospermia and multi-abnormal spermatozoa increased during 2008-2016 with slopes of 4.70 and 4.87, respectively, while for low semen volume, it decreased with a slope of -0.47 in the same time period. The proportion of patients with teratozoospermia increased from 2008 to 2011 and from 2011 to 2016 with slopes of 17.10 and 2.09, respectively. In general, the deteriorating trend of semen quality of infertile male patients in Wenzhou was obvious. Future efforts should be made to reveal the adverse influences on semen quality, such as occupational exposure, environmental quality, and living habits. Furthermore, more pervasive reproduction health education is necessary.Testosterone exerts an important regulation of cardiovascular function through genomic and nongenomic pathways. It produces several changes in cardiomyocytes, the main actor of cardiomyopathies, which are characterized by pathological remodeling, eventually leading to heart failure. Testosterone is involved in contractility, in the energy metabolism of myocardial cells, apoptosis, and the remodeling process. In myocarditis, testosterone directly promotes the type of inflammation that leads to fibrosis, and influences viremia with virus localization. At the same time, testosterone exerts cardioprotective effects that have been observed in different studies. There is increasing evidence that low endogenous levels of testosterone have a negative impact in some cardiomyopathies and a protective impact in others. This review focuses on the interrelationships between testosterone and cardiomyopathies and heart failure.One of the crucial challenges that any present-day general dentist confronts is the treatment determination between extracting a tooth and placement of a dental implant or by conserving the natural tooth with an interdisciplinary approach. The rising concern amongst the patients towards preserving their dentition has driven the clinicians towards providing treatment options that are more appropriate and conservative and at the same time does not hamper its functional needs. This report highlights one such way of preserving the periodontally compromised natural tooth with just resecting the diseased part of it and also conserving the proprioceptive capacity of the tooth. One-year of regular follow up and maintenance paving way to a healthy periodontium and complete resolution of mobility concerning the affected tooth is described. This report also provides information on root resection in a mandibular molar as a viable and a definitive treatment modality, providing better access to the remaining tooth structure and thereby enabling successive prosthetic rehabilitation.Medication-related osteonecrosis of the jaw (MRONJ) is a recurring complication resulting from the long-term therapy with bisphosphonates or antiresorptive drugs such as denosumab or antiangiogenic drugs. This paper describes a 5-years follow-up case of Stage 3 of MRONJ (AAOMS) in a 69-year-old patient treated with piezosurgery and topical application of platelet-rich fibrin (PRF). Medical treatment included antibiotic therapy and a topical treatment with PRF in solid and liquid form. This treatment showed initially the reduction of pain and leakage exudate and a complete wound healing in 25 days. The Injectable-Platelet Rich Fibrin (i-PRF) injections led to a complete resolution of oro-cutaneous fistulas in 50 days showing its ability of releasing growth factors and chemotaxis agents involved in tissue repair mechanisms. link3 Preparation simplicity and the low cost of PRF allow to consider this method as an excellent alternative treatment for the healing of tissues in MRONJ patients.Dentin dysplasia (DD) is a rare autosomal dominant disorder of dentin development, which is generally divided into two types based on the clinical and radiographic appearance of the affected dentinal tissues Type-I (Radicular DD) and Type-II (Coronal DD). This paper reports the case of a 17-year-old female patient with both classical and atypical features of radicular DD in the permanent dentition. The present case shows clinically normal appearing crowns, localised mobility in the maxillary teeth, completely obliterated pulp chambers, widened root canals without any obliterations and the presence of multiple periapical radiolucencies. The clinical and radiographic findings observed in this present case report are different from those reported in the past literature, which suggests that the present case could be a variation of radicular DD.Ameloblastoma is a true benign neoplasm of odontogenic epithelial origin mostly seen in the mandible. After odontoma, it is the second most commonly seen odontogenic neoplasm. Ameloblastoma comprises of several clinical, radiological and histological varieties, making it the most significant odontogenic neoplasm. Among these, the unicystic type is the least explored due to the fewer numbers of reported cases. Clinically and radiographically, it represents a cyst, but displays classic ameloblastomatous epithelial lining part of the cyst cavity, with or without intraluminal and/or mural tumor growth. We present an unusual case of unicystic ameloblastoma showing mural proliferation with mixed histological pattern [Plexiform, Follicular and Acanthomatous] of the mandible in a 32-year-old male.The majority of maxillary defects can be rehabilitated with pedicled flaps. However, when there are very large resections of the maxilla and flap success is questionable, then the defect may be obturated with a conventional hollow bulb clasp retained obturator or implant retained obturator prosthesis. However, inadequate retention, stability and support may be associated with the use of a conventional obturator and in case of recurrence the success of implant is questionable. A precision attachment becomes the silver lining. They have been used to retain obturator for some time. The use of precision attachments in a dentate maxillectomy patient can yield significant functional improvement while maintaining the obturator's aesthetic advantages. This clinical report describes the successful prosthetic rehabilitation of maxillary defects with an obturator retained using two different extracoronal resilient precision attachments. link3 Attachment retained prosthesis provides a successful closure for the defect but also better esthetics, retention, better tolerability and better mastication and speech.
