INTRODUCTION: Cavity preparations of posterior teeth have been frequently associated with decreased fracture strength of the teeth. Choosing the correct indirect restoration and the cavity design when restoring the posterior teeth i.e., premolars was difficult as it involves aesthetic, biomechanical and anatomical considerations. AIM: To evaluate the fracture resistance and failure pattern of three different cavity designs restored with monolithic zirconia. MATERIALS AND METHODS: Human maxillary premolars atraumatically extracted for orthodontic reasons were chosen...

The histidine-phosphorylatable phosphocarrier protein HPr, is an essential component of the sugar-transporting phosphotransferase system (PTS) in many bacteria. Recent interactome findings suggested that HPr interacts with several carbohydrate-metabolizing enzymes, but whether HPr plays a regulatory role was unclear. Here, we provide evidence that HPr interacts with a large number of proteins in Escherichia coli. We demonstrate HPr-dependent allosteric regulation of the activities of pyruvate kinase (PykF, but not PykA), phosphofructokinase (PfkB, but not PfkA), glucosamine 6-phosphate deaminase (NagB) and adenylate kinase (Adk)...

Some astronauts are returning from long duration spaceflight with structural ocular and visual changes. We investigated both the transient and sustained effects of changes in the direction of the gravity vector acting on the eye using changes in body posture. Intraocular pressure (IOP-Perkins tonometer), ocular geometry (axial length, corneal thickness, and aqueous depth-noncontact biometer), and the choroidal (volume and subfoveal thickness optical coherence tomography) was measured in 10 subjects (5M, 5F)...

The management of displaced, intra-articular calcaneal fracture represents a surgical challenge to even an experienced orthopedic surgeon. Plate osteosynthesis using an extended lateral approach is complicated by soft tissue problems, while those treated by closed reduction and percutaneous pinning cannot address all the intra-articular fragments sufficiently. The objective of our study is to evaluate restoration of subtalar joint and long-term functional outcomes in intra-articular displaced calcaneal fractures treated with transverse subcondral screws through a small incision on lateral aspect of calcaneus and percutaneously placed axial screws through the calcaneal tuberosity...

Multiple myeloma (MM) is a plasma cell neoplasm and constitutes 10% of hematologic malignancies. Malignant myelomatous pleural effusions are very rare and occur in <1% of cases of MM. In this article, we report a rare case of a patient who initially presented with pleural effusion and was subsequently found to be secondary to MM with an underlying raised IgG paraprotein. The patient symptomatically improved and was in partial remission with palliative radiotherapy, VTD chemotherapy, and bisphosphonates.

Leishmaniasis is a group of tropical diseases caused by protozoan parasites of the genus Leishmania. Leishmania donovani is a protozoan parasite that causes visceral leishmaniasis, a fatal disease if left untreated. Chemotherapy for leishmaniasis is problematic as the available drugs are toxic, costly and shows drug resistance, hence, there is a necessity to look out for the novel drug targets, chemical entities and vaccine. Glutamine synthetase (GS) catalyzes the synthesis of glutamine from glutamate and ammonia...

Acetylcholinesterase (AChE) enzyme has been predominantly used for the detection of pesticides and metal ions. But, these sensors respond to pesticides as well as metal ions at certain concentration, which results in poor selectivity. Hence in this work, the amount of thiocholine produced during AChE inhibition has been estimated to detect the residual activity of AChE enzyme in-turn to enhance the efficiency of the biosensor. In this context, Pt/ZnO-CeO2/AChE/Chitosan based biosensor has been developed for sensitive voltammetric quantification of thiocholine in AChE...

Carbon monoxide (CO)-releasing molecules (CO-RMs) are intensively studied to provide cytoprotective and anti-inflammatory effects of CO in inflammatory conditions including intestinal inflammation. The water-soluble CORM-A1 reduced apoptosis and NADPH oxidase (NOX)-derived reactive oxygen species (ROS) induced by tumor necrosis factor (TNF)-α/cycloheximide (CHX) in mouse MODE-K intestinal epithelial cells (IECs), without influencing TNF-α/CHX-induced mitochondrial superoxide anion ([Formula: see text]). The aim of the present study in the same model was to comparatively investigate the influence of lipid-soluble CORM-2 and water-soluble CORM-401, shown in vitro to release more CO under oxidative conditions...

BACKGROUND: Soybean (Glycine max) production is significantly hampered by frequent droughts in many regions of the world including the United States. Identifying microRNA (miRNA)-controlled posttranscriptional gene regulation under drought will enhance our understanding of molecular basis of drought tolerance in this important cash crop. Indeed, miRNA profiles in soybean exposed to drought were studied but not from the primary root tips, which is not only a main zone of water uptake but also critical for water stress sensing and signaling...

Endothelial dysfunction occurs when there are imbalances between factors that regulate the synthesis and degradation of nitric oxide (NO(•)), and has been reported in patients with hyperglycemia and insulin resistance. We reported that supplementation with γ-tocopherol (γ-T) in humans limits impairments in endothelial function otherwise induced by postprandial hyperglycemia. Given the rapid metabolism of γ-T into γ-carboxyethyl hydroxychroman (γ-CEHC), we hypothesized that the vasoprotective activities of γ-T could be attributed to its metabolite γ-CEHC...

Excessive demineralization in osteoporotic bones impairs its self-regeneration potential following a defect/fracture and is of great concern among the aged population. In this context, implants with inherent osteogenic ability loaded with therapeutic ions like Strontium (Sr(2+)) may bring forth promising outcomes. Micro-granular Strontium incorporated Hydroxyapatite scaffolds have been synthesized and in vivo osteogenic efficacy was evaluated in a long-term osteoporosis-induced aged (LOA) rat model. Micro-granules with improved surface area are anticipated to resorb faster and together with the inherent bioactive properties of Hydroxyapatite with the leaching of Strontium ions from the scaffold, osteoporotic bone healing may be promoted...
